Foward link power control of multiple data streams transmitted to a mobile station using a common power control channel

The present invention relates to the field of communication systems, particularly a method of controlling the transmission power level of a multiplex data stream transmitted from one or more base stations to a mobile station in a mobile wireless communication system.

In a mobile telephone communication system, one or several base stations transmit voice information and / or data to the mobile station. Each base station supports one or several sectors. For example, EIA / TIA-95-A In a CDMA system, each base station supports three individual sectors, and each sector has in common that it transmits different information. Voice and data transmission from a base station to one or more mobile stations is typically done on a forward link traffic channel. The mobile station receives information from the forward link traffic channel, decodes the information, and determines the frame error rate associated with the decoded information. The frame error rate of the decoded information is adversely affected, for example, by the fading state of the forward link channel. In addition, traffic channels can be transmitted from several base stations or from several sectors of the same base station. Mobile stations then combine signals from different sectors for improved decoding, often in a process commonly referred to in the prior art as soft handoff. A set of base station sectors that transmit the same data signal is usually named "active set". It will be understood by those skilled in the art that the term soft handoff means soft handoff between different base stations and soft handoff between different sectors of the same base station.

In some mobile radio communication systems, such as mobile radio systems that use code division multiple access (CDMA) modulation, the frame error rate of the mobile station is transmitted to the mobile station for forward link traffic signals. Used to control the power level. For example, in such a system, the desired signal-to-noise power ratio is obtained from the desired frame error rate. The evaluation of the actual signal-to-noise ratio received by the mobile station is then used to generate a power control command stream that is sent back from the mobile station to the active set base station. Each power control command in the power control command stream causes the base station to increase (eg, by 1 dB) the transmit power transmitted to the mobile station of the forward link traffic channel, decrease (eg, by 1 dB), or keep it constant.

The use of such a power control system allows the mobile station to increase transmission power to compensate the base station for fade-like conditions. Similarly, when channel conditions are more favorable, the power control system allows the base station to save power and the predetermined error rate is maintained using low transmit power.

In modern mobile communication systems, several data streams (eg fax transmission, internet transmission, voice call, etc.) can be transmitted to the mobile station at the same time. In systems such as CDMA systems, the transmission of such data streams can occur on the same forward link traffic channel (ie, frequency channel). In such cases, each data stream (eg voice, fax, internet, etc.) transmitted from a particular base station to a mobile station over a given forward link is often referred to as a Walsh code, and each data stream is a separate mobile station. Modulated using a different spreading code that allows it to be demodulated in. Different base stations can transmit on forward links with the same spreading code when they use different scrambling codes (often called PN codes).

If a large number of data streams are transmitted from one or more base stations to a mobile station over one or more forward links, the transmit power level of each data stream should be controlled as described above. However, returning a separate power control command stream from the mobile station to each base station over a reverse link, thereby controlling the transmit power of each data stream, results in a substantial increase in system overhead.

Therefore, when a base station transmits a large number of data streams to a mobile station, it is necessary to provide a system for forward link power control that minimizes the overhead required for returning a power control command from the mobile station to the base station. Is desirable.

The present invention is a mobile wireless communication system that controls the transmission power level of a first data stream transmitted from each base station of the first active set of a base station to a mobile station, and controls the transmission power level of the second active of the base station.

Is formed by. The power control signal is formed by the mobile station by interleaving the power control command stream, and the interleaved power control command stream is then transmitted to the base stations of the first and second active sets. The received power control command flow is formed by deinterleaving the received power control signal at a predetermined base station of the first and second active sets, and the first and second base stations from the predetermined base station. Both transmission power levels of the data stream are controlled according to the received power control command stream. Therefore, in this embodiment, one power control command stream controls the transmit power level of many different data streams (eg, voice data stream and fax data stream) transmitted from a common base station to a mobile station. used.

According to yet another property of the aforementioned embodiment, the second active set of the base station may be a subset of the first active set of the base station. In this case, the power control flow of each base station that is in the first active set but not in the second active set is formed according to only the first data flow from such a base station.

According to yet another embodiment, the present invention uses a single interleaved power control signal to transmit multiple power control command streams to each base station in both the first and second active sets. Each power control command stream is used to control the transmit power of different data streams transmitted from each base station to the mobile station. In this embodiment, the first and second data streams are transmitted from each base station in the first and second active sets and received by the mobile station. The power control command stream is composed of mobile stations according to the first received data stream from each base station in the first active set, and the power control command stream is the second from each base station in the second active set. It is composed of mobile stations according to the received data flow of. The power control signal is then formed at the mobile station by interleaving the power control command stream, and the interleaved power control signal is transmitted from the mobile station to each base station in the first and second active sets. The first and second received power control command streams are formed at a given base station, and by deinterleaving the received power control signal at a given base station in the first and second active sets. The transmit power level of the first data stream is then controlled from a predetermined base station according to the first received power control command stream, and the transmit power level of the second data stream is the second received power. It is controlled from a predetermined base station according to the control command flow.

According to yet another feature of the aforementioned embodiment, the second active set of the base station may be a subset of the first active set of the base station. In this case, the power control flow of each base station that is in the first active set but not in the second active set is formed according to only the first data flow from such a base station.

According to yet another feature, the measurement of the signal strength of the two corresponding data streams transmitted from the first and second base stations to the mobile station is a measurement of the signal strength of the two corresponding data streams transmitted from the two base stations. Tested to determine the power control command used to control the transmit power of one (or both). A feature of the invention is therefore that the first base station is used to generate power control commands that are used to control the transmission power of the corresponding data stream transmitted from the second (different) base station to the mobile station. Use information about the signal strength of the data stream transmitted from the station to the mobile station. The first data stream is transmitted from the first and second base stations to the mobile station, and the second data stream is transmitted from the first base station to the mobile station. In this embodiment, the first is by monitoring the signal quality of the first data stream received from the first base station and the signal quality of the first data stream received from the second base station.

Similarly, the second base station by monitoring the signal quality of the first data stream received from the second base station and the signal quality of the first data stream received from the first base station. The transmission power level of the first data stream from is controlled in the mobile station.

According to yet another feature, the measurement of the signal strength of the two corresponding data streams transmitted from the first and second base stations to the mobile station is a measurement of the signal strength of the two corresponding data streams transmitted from the two base stations. Tested to determine the power control command used to control the transmit power of one (or both). Therefore, this feature of the invention is also to generate a power control command used to control the transmit power of the corresponding data stream transmitted from the second (different) base station to the mobile station. Use information about the signal strength of the data stream transmitted from one base station to the mobile station. The first data stream is transmitted from the first and second base stations to the mobile station, and the second data stream is transmitted from the first base station to the mobile station. In this embodiment, the second is by monitoring the signal quality of the first data stream received from the first base station and the signal quality of the first data stream received from the second base station. The transmission power level of the first data stream from the base station is controlled in the mobile station. By monitoring the signal quality of the second data stream received from the first base station, the transmission power levels of the first and second data streams from the first base station are controlled in the mobile station.

The features of the invention described in the previous two paragraphs are generalized so that the system controls the transmission power of the corresponding data stream transmitted from each base station in the first active set to the mobile station. Different signal strengths from the corresponding data streams transmitted from the base station of the first active set to the mobile station are used to generate the power control commands used. In a more general embodiment, the first data stream is transmitted from the base station of the first active set to the mobile station, and the second data stream is from the base station of the second active set of one or more base stations. It is sent to the mobile station. The power control command stream of the first set is formed in the mobile station and transmitted to the base stations of the first active set, and each power control command stream of the set is all the base stations of the first active set of the base station. Determined according to the first data stream received from. The first and second base stations described in the previous two paragraphs are included in the base station's first active set, the second base station is included in the base station's second active set, and the base station's. The second active set may or may not be a subset of the first active set of the base station.

In yet another embodiment, the first power control command stream is formed at the mobile station according to the first and second data streams received at the mobile station from only the base stations of the second active set. The second power control command stream is the first or second data stream received by the mobile station from the base station that is in the first active set but not in the second active set, or It is formed in the mobile station according to both data flows. The mobile station then forms an interleaved power control command by interleaving the first and second power control command streams, the interleaved power control signal being transmitted from the mobile station over a reverse link. The interleaved power control signal is received by both the first and second active set base stations. The base station forms a first received power control command stream by deinterleaving the received and interleaved power control signal, and a second by deinterleaving the received and interleaved power control signal. Form the received power control command flow of. The transmit power levels of the first and second data streams transmitted by the base station of the second active set are then controlled according to the first received power control command stream and are in the first active set. The transmission power level of the first data stream transmitted by the base station not in the second active set is controlled according to the second received power control command stream.

According to yet another embodiment in which the communication system includes the first and second active sets, the first data stream is transmitted from the base station of the first active set to the mobile station, and the second data stream is It is transmitted from the base station of the second active set to the mobile station. In this embodiment, the second active set is a subset of the first active set. The first power control command stream is formed in the mobile station according to the first data stream received by the mobile station from the base station of the first active set. The second power control command stream is formed in the mobile station according to the first data stream, the second data stream, or both data streams received by the mobile station from the base station of the second active set. .. The mobile station then forms an interleaved power control signal by interleaving the first and second power control command streams, which interleaved power control signal from the mobile station to all base stations in both active sets. Will be sent. The interleaved power control signal is received at the base stations of both the first and second active sets. The base station forms a first received power control command stream by deinterleaving the received and interleaved power control signal, and a second by deinterleaving the received and interleaved power control signal. Form the received power control command flow of. The transmission power level of the first and second data streams transmitted by the base station in the second active set is controlled using the first command stream or a combination of both power control command streams. The transmission power level of the first data stream transmitted by the base station that is in the first active set but not in the second active set is the first received power control command stream or the first and It is controlled according to the combination of the second received power control command streams.

The previous embodiment is particularly useful when the second data stream is intermittent and is transmitted only from a subset of the base stations of the first active set.

In yet another embodiment where the radiotelephone communication system contains different first and second active sets, the first data stream is transmitted from the base station of the first active set to the mobile station and the second. Data flow is transmitted from the base station of the second active set to the mobile station. A single power control command stream is formed at the mobile station according to the first data stream received from the base station of the first active set. The mobile station then forms a power control signal with power control commands. Power control signals are transmitted from the mobile station to all base stations in both active sets. The power control signal is received at the base stations of both the first and second active sets. The base station of the first active set and the base station of the second active set form the received power control command flow by decoding the received power control signal. The transmit power level of the first data stream transmitted by the base station of the first active set and the transmit power level of the second data stream transmitted by the base station of the second active set are then received. It is controlled according to the power control command flow. The difference in transmitted power between the first and second data streams is regulated by separate mechanisms. For example, the message transmission time and the time from the mobile station to the base station or external loop are based on the currently measured QoS and the desired QoS of the second data stream after it has been decoded by the mobile station. This QoS is frame error rate or other.

In another embodiment of the previous embodiment, the power control command is based on both the first and second data streams received by the mobile station.

In the aforementioned embodiments, the mobile station preferably forms each power control command stream by monitoring the frame error rate or signal-to-noise ratio associated with a given received data stream. Further, the first and second power control command streams are preferably generated according to the interleave pattern, and commands from each power control command stream are only generated and inserted when requested by the interleave pattern. This ensures that there are no extra commands for sending delaying new commands. This also ensures that the interleaving process does not unnecessarily delay power control commands from one to the other.

Detailed explanation

The features, objects and advantages of the present invention will become even more apparent from the detailed description described below with reference to the drawings. The same code is the same for the corresponding elements throughout. Figure 1A shows an interleaved power control bit stream 110 for controlling the transmit power levels of multiple different data streams 120, 120A, 122, 122A, 124, 124A transmitted from one or more base stations to a mobile radio station. Indicates a mobile radio station 100A that generates. The data streams 120, 122, ... 124 propagate the same information (eg, the same audio transmission) and are transmitted from the base stations of the first active set (ie BS1, BS2, ... BSn). Data streams 120A, 122A, ... 124A propagate the same information (eg the same internet or fax transmission) and are transmitted simultaneously from a second active set base station (ie BS1, BS2, ... BSn). .. The base station of the second active set may or may not be a subset of the first active set, as will be further fully described below in connection with various other embodiments. Data flow 120, 120A, 122, 122A, 124 , 124A are transmitted to mobile radio stations in a common frequency band using, for example, code division multiple access (CDMA) or time division multiple access (TDMA) modulation. A large number of data streams from different base stations, for example, when a mobile radio station is soft handed off between two or more base stations, or when diversity signals are used to achieve good reception at the mobile station. Used to transmit multiple displays of the same information to mobile radio stations. Many versions of transmitting the same data signal from different base stations to a given mobile station for soft handoff or transmission diversity are well known in the art.

In mobile station 100A, the data stream 120 received from BS1 and 120A are given to the power control command generator 130, and this power control command generator 130 transfers a single command stream of power control commands from the received data stream. Occur. In the embodiment of FIG. 1A, the power control command generator 130 optionally selects data stream 120 or data stream 120A (or a combination thereof) for monitoring. The power control command generator 130 then receives a signal-to-noise ratio or frame error ratio (or reception associated with both data streams 120, 120A if the combination is monitored) associated with the selected data stream. It monitors the signal-to-noise ratio or frame error rate) and issues a series of forward link power control commands 140 based on this information. Each power control command in the command stream 140 is, for example, the data stream 120. , Represents a BS1 command indicating that BS1 should increase or decrease the transmit power level used to transmit the next frame of 120A to mobile radio station 100A. It is well known in the art to derive such a power control command stream using the received signal-to-noise ratio or the frame error ratio of one received signal. When a combination of data streams 120, 120A is monitored, the sum of the received signal-to-noise ratios associated with each data stream is from the combination of data streams 120, 120A to generate the power control command stream. It is preferably compared to a threshold that represents the sum of the expected desired signal-to-noise ratios. In the embodiment of FIG. 1A, one common power control command stream 140 therefore uses one or both of the two data streams to use both data streams 120. , Occurs for 120A. This feature of the present invention is that when a large number of data streams are transmitted from a base station to a given mobile station on a forward link traffic channel, the fading state of the traffic channel is similar from base station to mobile station. It can affect all transmitted data streams, so a single (or common) power control command stream controls the transmit power of all data streams transmitted from a base station to a given mobile station. Recognize that it can be used.

Referring to FIG. 1A, the data stream 122 and 122A received from BS2 are given to the power control command generator 132, and this power control command generator 132 transfers one command stream of the power control command from the received data stream. Occur. In the embodiment of FIG. 1A, the power control command generator 132 optionally selects data stream 122 or data stream 122A (or a combination thereof) for monitoring. The power control command generator 132 then receives the signal-to-noise ratio or frame error ratio (or reception associated with both data streams 122, 122A, if the combination is monitored) associated with the selected data stream. It monitors the signal-to-noise ratio or frame error rate) and issues a series of forward link power control commands 142 based on this information. Each power control command of the command flow 142 moves, for example, the next frame of the data flow 122, 122A. Radio station 100 Represents a BS2 command indicating that BS2 should increase or decrease the transmit power level used to transmit to. It is well known in the art to derive such a power control command stream using the received signal-to-noise ratio or the frame error ratio of one received signal. When a combination of data streams 122, 122A is monitored, the sum of the received signal-to-noise ratios associated with each data stream is from the combination of data streams 122, 122A to generate the power control command stream. It is preferably compared to a threshold that represents the sum of the expected desired signal-to-noise ratios. In the embodiment of FIG. 1A, one common power control command stream 142 is generated for both data streams 122, 122A using one or both of the two data streams.

The data streams 124 and 124A received from BSn are given to the power control command generator 134, and this power control command generator 134 generates one command stream of power control commands from the received data stream. In the embodiment of FIG. 1A, the power control command generator 134 optionally selects data stream 124 or data stream 124A (or a combination thereof) for monitoring. The power control command generator 134 then receives the signal-to-noise ratio or frame error ratio (or reception associated with both data streams 124, 124A, if the combination is monitored) associated with the selected data stream. It monitors the signal-to-noise ratio or frame error rate) and issues a series of forward link power control commands 144 based on this information. Each power control command in the command stream 144 moves, for example, the next frame of the data stream 124, 124A. Radio station 100 Represents a command to BSn indicating that BSn should increase or decrease the transmit power level used to transmit to. It is well known in the art to derive such a power control command stream using the received signal-to-noise ratio or the frame error ratio of one received signal. When a combination of data streams 124, 124A is monitored, the sum of the received signal-to-noise ratios associated with each data stream is from the combination of data streams 124, 124A to generate the power control command stream. It is preferably compared to a threshold that represents the sum of the expected desired signal-to-noise ratios. In the embodiment of FIG. 1A, one common power control command stream 144 is generated for both data streams 124, 124A using one or both of the two data streams.

Data flows from three base stations are shown to be received by mobile station 100A, but mobile station 100 is configured to receive data signals from more (or fewer) different base stations than three. May be done.

Power control command streams 140, 142, 144 are given to the multiplexer 146 controlled by interleaver controller 148. The multiplexer 146 combines separate power control command streams 140, 142, 144 into a single interleaved power control bit stream 110. The transmitter 150 returns the interleaved power control bit stream 110 to the base station (BS1, BS2 ... BSn) on the power control channel or subchannel.

In a preferred embodiment of the invention, each base station of the first set of active base stations simultaneously transmits a version of the first data stream (eg, signals 120, 122, 124 of FIG. 1A) to mobile station 100. Each base station in the second set of active base stations simultaneously transmits a version of the second data stream (eg, signals 120A, 122A, 124A) to mobile station 100. The base station of each active set preferably monitors the pilot signal from the base station near the mobile station 100, and bases on the active set when the pilot signal from the base station falls above or below the threshold. It is maintained by adding or erasing stations from it. It is well known in technology to use pilot signals from base stations to maintain the active set of base stations. In a preferred embodiment, the set of active base stations does not have to be the same, but one set of active base stations (eg, a second set) is typically the other set of active base stations (first set). A subset of). As described below, in some embodiments of the invention, the second active set of the base station is not a subset of the first active set.

In Figure 1A, the first set of active base stations that simultaneously transmit the first data stream version (eg, the signals 120, 122, 124 in Figure 1A) to the mobile station is the second data stream version (eg Figure 1A). It was identical to the second set of active base stations that simultaneously transmitted 1A signals 120A, 122A, 124A) to mobile stations. FIG. 1B shows another preferred embodiment of the mobile radio station of FIG. 1A in which different sets of active base stations transmit different data streams to the mobile radio station. In Figure 1B, mobile radio station 100B receives different data streams 120 and 120A from BS1, only one data stream 122 from BS2, and only one data stream 124 from BSn. Therefore, in FIG. 1B, the first active set of base stations (ie BS1, BS2, BSn) simultaneously transmits a version of the first data stream (ie signals 120, 122, 124 in FIG. 1B) to mobile station 100B. , The second set of active base stations formed solely from BS1 is the second data stream (ie signal 120) ) Is transmitted to mobile station 100A. The base station active set used to transmit the data stream to the mobile station is not the same, for example, when the mobile station is soft handed off between base stations with different active sets, as shown in Figure 1B. You may. In the embodiment shown in FIG. 1B, the power control command generators 132A and 134A monitor the data streams 122 and 124 to generate the power control command streams 142 and 144, respectively, as described above.

FIG. 1C generates an interleaved power control signal 110 for controlling transmission power levels of a plurality of different data streams transmitted from one or more base stations to a mobile station according to another preferred embodiment of the present invention. Shows mobile radio station 100C. In contrast to the embodiments of FIGS. 1A and 1B, in the embodiment of FIG. 1C, the transmission power levels of different data streams transmitted from the same base station to the mobile station are the power control commands contained in the interleaved power control signals. Controlled using different command streams.

Therefore, in the mobile station 100C, the data streams 120 and 120A received from BS1 are given to the power control command generator 131, and this power control command generator 131 has different command streams of power control commands from each received data stream. Occurs. The power control command generator 131 monitors the received signal-to-noise ratio or frame error rate associated with the data flow 120 and generates a series of forward link power control commands 140A based on this information. Each power control command generator 131 separately monitors the received signal-to-noise ratio or frame error rate associated with the data flow 120A and uses this information to issue a separate set of forward link power control commands 140B. Occur. Each power control command of command flow 140A and 140B moves, for example, the next frame of data flow 120 and 120A. Radio station 100 Represents a command to BS1 indicating that BS1 should increase or decrease the transmit power level used to transmit to. It is well known in the art to obtain such a power control command stream using the received signal-to-noise ratio or the frame error ratio of the received signal.

Referring to FIG. 1C, the data streams 122 and 122A received from BS2 are given to the power control command generator 133, and this power control command generator 133 sends different command streams of power control commands from each received data stream. Occur. The power control command generator 133 monitors the received signal-to-noise ratio or frame error rate associated with the data flow 122 and generates a series of forward link power control commands 142A based on this information. Each power control command generator 133 separately monitors the received signal-to-noise ratio or frame error rate associated with the data flow 122A and uses this information to issue a separate set of forward link power control commands 142B. Occur. The command stream 142A, 142B power control commands, for example, indicate that BS2 should increase or decrease the transmit power level used to transmit the next frame of data stream 122, 122A to mobile radio station 100. Represents the command to BS2 shown.
