DESCRIPTION OF EXEMPLARY MODALITIES

While this technology is capable of being performed in many different ways, various specific modalities are shown in the figures and will be described here in detail with the understanding that the present disclosure should be considered as an exemplification of the principles of technology and is not intended to limit technology to the illustrated modalities.

It will be understood that similar or analogous elements and / or components, referred to herein, can be identified throughout the drawings with similar reference characters. It will further be understood that several of the figures are merely schematic representations of the present technology. C As such, some of the components may have been deformed from their actual scale for graphic clarity.

Generally, the present technology can provide high capacity wireless communications between one or more baseband units ("BBUs") and one or more radio frequency units ("RFUs") within a wireless network assembly, such as a base station (“BS”). The BBU and RFU communicate digitally with each other through a two-way transport interface. Signals representing bearer data that can be transmitted and received by the antenna (s) associated with the base station (BS) can be sent in a format known as "I / Q" which means "in phase / quadrature ”. Other information that does not represent carrier data may also be communicated between the BBU and the BFU. These two types of information are typically multiplexed into digital fronthaul data. While in some cases, an implemented system of According to the method described here you can generate the I / Q encoded carrier data directly as RF carriers (i.e. in an analog format), one of ordinary skill in the art would recognize that such a system would implement an internal interface where this data is digitally encoded. as quantized I / Q data before generating this signal as analog data.

More specifically, the BBU and RFU may be communicatively coupled using a standardized / approved open protocol (eg, interface, a proprietary protocol, or a combination thereof). In some embodiments, the protocols used between the BBU and the RFU facilitate two-way transmission of the digital fronthaul data between the BBU and the RFU either by fiber optics or other types of wired coupling. In one embodiment, time division multiplexing can be used to carry various types of information such as general information, l which may include, but is not limited to control, command, timing, and other data, other than "I / Q" information. Radio signals comprising carrier data, also referred to as "traffic data" or "I / Q data", can be transmitted and received by various antennas associated with the Base Station.

These protocols can be entirely digital in nature and their performance can range from approximately 600 megabits / s to 10 gigabits / s, inclusive. The structure of these protocols typically includes a set number of words representing general information and a set number of words representing data.

I / Q. In some cases the set number of words representing the general information may be relatively less than the set number of words representing the I / Q data.

Normally, in order to carry both I / Q data and general information, I / Q data (eg radio signal information) is transmitted as a whole in digital form. Digital and / or multiplexed currents can be handled by the system at gradually increasing throughput rates. For example, digital currents in the order of approximately tens of gigabits / s can be transmitted corresponding to I / Q data from radio access technologies such as

3G / 4G, "Long Term Evolution" LTE, Advanced LTE, and so on.

Due to its almost limitless capacity, fiber optic media can be used to transmit I / Q data. Other solutions

Ί contemplate transmitting digital and / or general I / Q data using wireless networks. One solution involves the use of radio waves. This solution requires a substantial throughput rate in order to transport the entire structure (for example, both I / Q and general data), and thus, use of width d may be required e substantial band or sophisticated modulation. These exemplary methods are described in greater detail in European Patent 1534027. Another solution contemplates the use of optical waves, as indicated in the publication document of the US Patent Application number 2003-027597. While both of these wireless systems propose a digital solution to connect the BBU module to the RFU radio, these systems suffer from drawbacks including, but not limited to the fact that the performance (eg fronthaul) of these systems it is very substantial.

Advantageously, the present technology allows the transmission of information using wireless systems in such a way that a substantial reduction in the performance measure between the BBU and the RFU is achieved while ensuring a complete transmission of I / Q data, which is constantly evolving and growing over time. These and other advantages of the present technology will be of written in greater detail below with reference to the drawings.

Now referring to Fig. 1, which illustrates an exemplary architecture for practicality aspects of the present technology. A base station (BS) 1 is shown comprising a baseband unit (BBU) 2, which is communicatively coupled with the core network (CN).

The CN manages the communicative coupling with a public telephony (PSTN) or data network. The BBU 2 can be communicatively coupled with a BBU 5 Connection Unit via any suitable route or channel that allows the transmission of digital data.

The BS 1 may also comprise a series of radio frequency units, such as a radio frequency unit (RFU) 3a and 3b. In this example, two RFUs are present. In one case, RFU 3a may be communicatively coupled with a coupling module of

RFU 6a through a communication channel 9 which can allow mixed analog or analog and digital transmission. In the other case, the RFU 3b can be communicatively coupled with the RFU 6b coupling module via a digital communication channel 22. In one embodiment, RFU 3a may be communicatively coupled to an antenna 4a via a second communication path 10a and RFU 3b may be communicatively coupled to an antenna 4b via a second communication path 10b. The BBU 5 coupling module additionally communicates with all RFU coupling modules 6a and 6b via a wireless communication channel 7a or 7b, also referred to as a "wireless network segment".

Figs. 1, 2, 4 and 5 together illustrate an exemplary system and method for transmitting information using the system of Fig. 1. According to some embodiments, the BBU 2 can be communicatively coupled to the CN core network according to methods that would be known to one with skills s ordinary in the art with the present disclosure in front of them.

The BBU 2 communicates with at least one of the RFUs 3a or 3b using the BBU 5 coupling unit, to which the BBU 2 is communicatively coupled via a digital communications channel 8. While the BBU 5 coupling unit and BBU 2 have been shown as being separate devices, in some cases the coupling unit of BBU 5 and BBU 2 may be integrated in the same device. In some embodiments, digital protocol frames 80 may be transmitted between BBU 2 and RFU 3 via a BBU 5 coupling unit using digital communication channel 8. It should be noted that a digital protocol frame 80 can comprise a series of words related to information of two types: (a) words that correspond to general information; and (b) words that correspond to "I / Q" radio signal information. While the method contemplates Using "words" to differentiate between the two basic types of information included in the digital fronthaul data, the system may be configured to differentiate types of information using any other differentiators that may also be used in accordance with the present technology.

Generally, a method of transmitting information may comprise separating digital fronthaul data into the two basic data types, comprising I / Q data and general data. In some cases, separating digital fronthaul data may include demultiplexing from digital fronthaul data when evaluating digital protocol frameworks 80.

In another method, the method for transmitting information may comprise separating analog RF signals and general data, and transmitting them on two different channels.

Digital protocol frameworks can be evaluated to differentiate words related to general information from words ras related to radio I / Q signal information in each of the digital protocol frameworks 80.

Once again, data included in the digital protocol frameworks 80 can be demultiplexed in a demultiplexing module 51 in the BBU 5 coupling module. The BBU 5 coupling module can then transmit the demultiplexed types of information via the wireless communications 7 using an antenna 50. More specifically, the digital protocol frames 80 can be separated into general information and radio frequency information. General information can be extracted from protocol frameworks 80 by demultiplexing module 51 and passed as digitally modulated data by digital modulator module 52. Radio frequency information can be further separated into information constituting frequency carrier signals 71-74 radio, also referred to as carrier images and mo consequently dulated in radio frequency carriers 71-74 by means of a module 53.

Words related to general information can be transmitted through a digital communication channel of wireless communication channel 7 using digital modulation. With respect to I / Q radio signals, it should be noted that I / Q radio signals ultimately have bearers intended for transmission or reception by antenna (s) 4 associated with base station 1 . Base station 1 can process radio I / Q signals with the appropriate technologies required by radio access interfaces (

Radio Access ("RAT"), which allows communication between mobile phones and antennas 4 of BS 1.

Next, the BBU 5 coupling module can be configured to separate the words related to radio I / Q signals into a series of radio frequency carriers. The info Information pertaining to I / Q radio signals contained within the digital protocol framework 80 is transmitted as radio frequency carriers 71, 72, 73, via the BBU 5 coupling module via wireless communication channel 7.

It will be understood that the transmission of I / Q radio signals 20 used by wireless communication channel 7 may be based on similar radio access technologies implemented by the one or more RFU 3 for the carriers and RAT in question, transmitted and received by antennas 4 and associated with RFU 3. For example, the radio technology used to transmit the I / Q radio signals can improve the efficiency of data transmission over the wireless communication channel 7 in relation to various performance characteristics of the wireless medium.

These performance characteristics include, but are not limited to 5 line of sight propagation, point-to-point topology, in minor interference, and so on.

Words related to radio I / Q signals are converted to radio frequency carriers 71, 72, 73, 74 using technologies that would be known to one with ordinary skill in the art such as filtering, digital up-conversion "DUC", mixed I / Q, mixed, digital / analog conversion, and so on.

Advantageously, the transmission of radio I / Q signals in the form of radio frequency carriers can be transparent at the rates of return proposed by RATs of BS 1 operators, such as the integrity of radio I / Q signals. Q, carrier "images", and RATs, transmitted and received by antennas 4 is sufficiently maintained with respect to the overall performance of wireless communication channel 7. In some cases, transmission of I / Q radio signals in the form of radio frequency carriers can be accomplished in a non-transparent manner. tea.

Furthermore, the necessary bandwidth for the wireless communication channel 7 can be as defined by the associated RAT (s), which are transmitted and received by the antennas 4 associated with the RFU 3.

As a final result, a series of radio frequency carriers 71, 72, 73, 74 for each digital protocol frame 80 can be transmitted through wireless communication channel 7, and one or more digital modulations can be used to transmit the general information protocol elements. The series of radio frequency carriers 71, 72, 73, 74 and the digitally modulated transmissions 75 are then received by the coupling module of

RFU 6 using an antenna 60.

Next, the RFU coupling unit 6b can perform a method of reassembling the fronthaul signals and data from the previously separated data (eg, radio signals I / Q and general information). An exemplary method of transmitting information may further comprise converting the series of radio frequency carriers 71, 72, 73, 74 into a series of words representing the I / Q radio signal information. Again, techniques that would be known to one of ordinary skill in the art can be used, such as filtering, "DDC" digital downconversion, I / Q mixing, mixing, digital / analog conversion, and so on. Digitally modulated transmissions 75 can be used by RFU 3b according to a pre-established protocol.

More specifically, the method may include conversion by a conversion unit 63 of the radio frequency carrier series 71, 72, 73, 74 to a series of words representing the content of the radio I / Q signals, and demodulation of digitally modulated data in words representing general information 61. The word series s can be multiplexed by re-assembling the words to recreate digital protocol frames 220, which correspond to digital protocol frames 80 which were previously demultiplexed. Digital protocol frameworks 220 are then transmitted to RFU 3b through a second communication channel 22. The second communication channel 22 may allow transmission of digital and / or analog data.

In order to ensure proper reconstruction of the digital protocol frameworks 220, synchronization information is transmitted between the BBU 5 coupling module and the RFU 6b coupling module to allow general information and radio signal information I / Q of digital protocol frameworks 220 are returned to a consistent form.

The digital protocol generally used to transport frames 80 (after demultiplexing), 220 (after demultiplexing) allows distances substantial between the BBU and the RFU. Therefore, those protocols can tolerate significant proportional delay on either a wired or wireless link. For example, for every 10 kilometers of optical fiber used, a delay of 55 microseconds can be observed.

Additionally, it is possible to temporarily store the general information or the I / Q information in a buffer zone within the RFU coupling module 6b. This allows for more consistent processing of all (or a substantial portion of) the information received based on synchronization information, using the RFU coupling module 6b.

In another exemplary embodiment where information not useful for the digital protocol framework 80 is removed in order to remove useless information. For example, words that are not completed or used may be removed. In this way, only necessary information can be transmitted, reducing provides Only the volume of information transmitted.

Fig. 3 illustrates another exemplary embodiment where the RFU 6a coupling module and RFU 3a form a wireless remote radio head (RRH). In accordance with some embodiments, the RFU coupling module 6a retransmits the radio frequency carriers 71, 72, 73, 74 to the RFU via a first communication channel 9, for retransmission via antenna 4a associated with RFU 3a. In accordance with some embodiments, the RFU coupling module 6a may not multiplex the general information words and in some cases it may not convert the radio frequency carriers 71, 72, 73, 74 into words related to the signal information I / Q radio. Consequently, the aforementioned digital protocol frameworks 220 may be unreconstructed by the RFU coupling module 6b.

Alternatively, the RFU coupling module 6b can adapt the frequency carriers d e radio 71, 72, 73, 74 based on the associated RATs for transmission via delay antenna 4b associated with the

RFU 3b.

In some cases the general information can be processed by the RFU 6 coupling module (for example, instead of being transmitted to 3 which then uses it to perform control or management tasks). In some cases, in addition to the first communication channel 9, which may comprise an analog communication link, there may be a separate control interface (such as an API) over which a control and management process can take place.

The term "process" can be understood as including the modification of RF signals based on the content control information included in the general information.

According to some modalities, a BBU 6a docking module can be used to interpret and use the general information in order to perform var Actions, such as actions taken by RFU 3a with respect to the same type of information. Thus, it may no longer be necessary to transmit complete general information to RFU 3a, which may result in a reduction in the amount of information in the digital protocol framework, leading to more efficient data transmission.

It should be noted that in an exemplary operation, data may be transmitted between BBU 2, serving as a transmitter, to one of RFUs 3, serving as a receiver. However, data can likewise be transmitted between one of the RFUs 3, in this case serving as a transmitter, to the BBU 2, which in this case would serve as a receiver.

Advantageously, the present technology can allow the processing of radio frequency carriers in terms of bandwidth (MHz / bandwidth) rather than in terms of throughput (Mbit / s) via wireless communication channel 7. Once Furthermore, the wireless communication channel 7 can communicatively couple the BBU 2 and the series of RFUs 3 of the BS 1. This configuration allows a digital solution that benefits from the modulation efficiency of the technologies implemented in this wireless communication channel 7.

Additionally, spectrum efficiency can be maintained transparently with respect to the Radio Access Technology used in the wireless communication channel 7. The present technology can also benefit from the inherent advantages of line-of-sight / non-line-of-sight technologies. "LoS / NLoS" vision between fixed stations and individual users. Additionally, this method allows the use of different frequency bands to transmit different signals according to the methods described in European Patent number 1895681.

In some cases the present technology advantageously houses complementary diversity technologies for increase efficiency such as multi-polarization, line-of-sight multiple-input-multiple-output "LoS MIMO", and so on.

While the methods and systems for transmitting information described above are related to the field of mobile telephony, the present technology may be applicable to many types of radio networks such as "PMR" public mobile radio networks used by law enforcement and first transponders, as well as any radio system that includes radio stations and antennas or active and / or radar antennas - to name a few.

Fig. 8A illustrates an exemplary functional implementation of a fronthaul module 270 in accordance with the present technology. The fronthaul module 270 features a digital interface 263 using for example a fiber optic medium. Traffic on fronthaul interface 263 comprises a multiplexed signal that includes several fronthaul signals which are transmitted between a baseband unit and a plurality of mobile wireless transceivers, which are communicatively coupled together via the wide area radio access network. An exemplary mobile wireless transceiver is represented as

269. An interface processing module 271 demultiplexes and multiplexes two or more of the fronthaul signals (eg, fronthaul signals 266a, 266b, 267, and 268) according to a predefined multiplexing algorithm. Fronthaul signals may contain the fronthaul information for the subset of mobile wireless transceivers for which they are intended. A fronthaul signal 266a is fed into a processing unit 272a which breaks down the fronthaul signal 266a into an RF bearer signal constructed from the I / Q data contained within the fronthaul signal 266a, general control data. digitally modulated and digitally modulated user information, both s contained in the fronthaul signal 266a, and multiplexed together into a signal 265. A similar process applies for 266b through 272b and producing a signal 264. The fronthaul signal 267 is transmitted on a mobile wireless transceiver 269 which may be integrated within the fronthaul module 270 or communicatively coupled with the fronthaul module via a Interface.

A multiplexed signal 265 is fed into an interface module 275, which can use a cable medium 276 comprising any of fiber optics, coaxial cable or copper wire. A multiplexed signal 264 can be fed into an interface module 274, which can use a wireless medium 277. The interface module 274 can be implemented as a radio and antenna transceiver with the appropriate performance to transmit the multiplexed signal 264 over a certain distance. A fronthaul signal 268 is fed into a digital interface module 273 that p You can use a high capacity wired medium

278. The signal transiting on this interface consists of the relevant fronthaul information to provide fronthaul signals to mobile wireless transceivers for which they are intended.

While the above represents one direction of signal flows, all interfaces and modules are designed to process bidirectional signals, so that each operation has its symmetrical function to handle traffic in the other direction.

Fig. 8B illustrates another exemplary fronthaul module constructed in accordance with the present technology. In this case a fronthaul module 290 uses a wireless interface 288 to receive data received from the baseband unit located within the Wide Area Radio Access Network (eg wireless network) and to transmit data received from one or more mobile wireless transceivers, to the baseband unit and. The signals at this wireless interface may comprise multiplexing of modulated RF carriers, digitally modulated general control signals, and digitally modulated user information.

An interface module 291 includes a wireless transceiver for processing the wireless signals and for demultiplexing the aggregated fronthaul signals into individual fronthaul signals which are transmitted fronthaul processing modules 292a, 292b, 292c and

292d, as well as in a 293 interface module. It should be noted that two types of multiplexing can occur: (1) multiplexing of several fronthaul signals destined for multiple RRUs (mobile wireless transceivers); and (2) multiplexing the RF carriers with the control information and with the user information for each individual fronthaul signal, as well as multiplexing the fronthaul signals of the mobile wireless transceivers which are intended for the baseband unit (reverse operation). The purpose of 292a, 292b, 292c and 292d is to transform the digital fronthaul signal into a multiplexing of radio bearers, digitally modulated and digitally modulated user control information, resulting in 283, 284, 285 and 286 digital fronthaul signals, respectively.

In the present example, a digital fronthaul signal 283 is transmitted to a mobile wireless transceiver 289, which is equipped with a digital wireless fronthaul interface. An example of such an interface is given by the Common Public Radio Interface or CPRI standard and the corresponding systems are sometimes referred to as Remote Radio Heads (RRH) or Remote Radio Units (RRU). Instead, a digital fronthaul signal 283 is also used to carry uplink signals from the mobile wireless transceiver 289 and intended for the baseband unit. In this case, the digital fronthaul signal pu It can contain only the relevant fronthaul signal for the 289 mobile wireless transceiver.

In the present example, a digital fronthaul signal 284 is provided to a digital fronthaul interface unit 296 which provides an external digital fronthaul interface 282 used to transmit and receive relevant fronthaul information for the mobile wireless transceivers located in the part corresponding network (ie, "behind" this port). In this case, the digital fronthaul signal 282 may contain the relevant fronthaul signal for those mobile wireless transceivers. As an example, the 282 digital fronthaul interface can use high capacity fiber media.

In another example, a digital fronthaul signal 285 is transmitted to a fronthaul interface unit 295 which provides an external interface 299 used to transmit and receive relevant fronthaul information to the l Mobile wireless transceivers located in the corresponding part of the network (that is, "behind" this port). In this case, the fronthaul signal 299 comprises RF bearer multiplexing, digitally modulated control information, and digitally modulated user information carried on a wired medium. In this case, the fronthaul signal 299 can contain only the relevant fronthaul signal for those mobile wireless transceivers. As an example, the fronthaul 299 interface can use a fiber medium (or a wavelength of a fiber) or a coaxial cable medium. (In the present example, the digital fronthaul signal 286 is used to power the wireless fronthaul interface unit 294 which provides an external wireless interface 298 used to transmit and receive relevant fronthaul information for the mobile wireless transceivers located in the corresponding network (ie, “of behind ”this port)). In this case, the fronthaul signal 298 comprises RF bearer multiplexing, digitally modulated control information, and digitally modulated user information carried on a wired medium. In this case, the wireless fronthaul signal 298 may contain the relevant fronthaul signal for those mobile wireless transceivers. As an example, the wireless fronthaul interface 299 may comprise a properly designed RF transceiver and antenna.

In the present example, a fronthaul signal 287 is a multiplexing of RF carriers, digitally modulated control information, and digitally modulated user information carried between an interface module 291 and a wireless interface module 293. The wireless interface module 293 it may comprise a properly designed RF transceiver and antenna. In this case, the wireless fronthaul signal 287 and the wireless fronthaul signal 297 pu They can understand the relevant fronthaul signal for those mobile wireless transceivers located in the corresponding part of the network. In this case, no conversion to digital fronthaul format is required.

FIG. 6A is a flow diagram of an exemplary method 600 for transmitting information via a wireless communication channel.

According to some embodiments, method 600 may comprise a step 605 of separating, via a transmitter unit, a stream of digital fronthaul data into general information and radio signal information using a digital protocol framework. According to some embodiments, step 605 of separating can include demultiplexing of general information and radio signal information from digital fronthaul data.

In some cases, at step 605 of separating, information that does not belong to the digital protocol framework can be removed to reduce the amount of unnecessary data that is transmitted over the wireless network segment. This feature can reduce the latency of the wireless network segment, while also reserving network bandwidth for increased consumption and transmission of radio signal information and / or general information.

Additionally, method 600 may comprise a step 610 of dividing the radio signal information into radio frequency carriers as well as a step 615 of transmitting the radio frequency carriers between the transmitter and receiver. The transmission of the radio signal information and / or bearer is carried out using appropriate radio access interface technologies. Once again, the radio access technologies used can be optimized or improved with respect to the selected transmission method or medium. Furthermore, a step 620 may include a step of transmitting the general information via the transmitter unit to a receiver on a second communication channel. In some cases, the transmitter and receiver may be communicatively coupled to each other using a digital communications channel.

In some cases, general information can be transmitted over the wireless network segment by digital modulation of the general information.

Fig. 6B is a flow chart of an exemplary method 625 for transmitting information. It should be noted that the method described with respect to Fig. 6A specifies the separation of digital fronthaul data into constituent parts to improve the transmission of the constituent parts over a wireless network segment. Method 625 in Fig. 6B contemplates the reassembly of the separate parts transmitted over the wireless network segment in such a way that the digital fronthaul data is recreated.

Method 625 may include a step 630 of digitally demodulating general information as it is received by the receiver (or earlier to receive the general information). Similarly, method 625 may include a step 635 of re-converting the bearer array into radio signal information such as digital I / Q data. Again, the radio signal information is a digital (or in some cases analog) signal. By extension, step 635 allows a step 640 to reconstruct the digital protocol frameworks used by the receiver. After rebuilding the digital protocol frameworks, the method may include one step

645 of multiplexing digital protocol frameworks to retrieve digital fronthaul data. Importantly, the retrieved digital fronthaul data may include less data than the original digital fronthaul data if unnecessary data was removed during a subsequent step of evaluating digital protocol frameworks.

Although not shown, exemplary methods may also include steps such as conveying information without chronify general information and radio signal information as well as store both general information and radio frequency information before synchronizing general information and radio signal information. This synchronization may depend, in part, on the synchronization information used. It should be noted that the transmission steps can be carried out in different frequency bands. Additionally, in some embodiments the transmitter may include a baseband unit and the receiver may include at least one radio frequency unit, or vice versa.

Other exemplary methods may include the step of processing general information in the BBU 5 docking module before transmitting it. The term "process" can be understood to include the modification of RF signals based on the content control information included in the general information.

As previously mentioned, while the m Methods described above for transmitting information have been described in relation to a base station (BS) of a mobile telephone communication system, the methods for transmitting information are applicable in any suitable field that would be known to one with ordinary skill in the art with the present disclosure against it.

Fig. 7 illustrates an exemplary computing system 700 that can be used to implement an embodiment of the present technology. The computer system 700 of FIG. 7 includes one or more processors 710 and a memory 720. A main memory 720 stores, in part, instructions and data for execution by the processor 710. The main memory 720 can store the executable code when system 700 is in operation. System 700 of Fig. 7 may also include a 730 mass storage device, 740 portable storage media reader (s), 750 output devices, devices user input 760, a graphics display 770, and other peripheral devices 780.
