Wireless communication method and apparatus for reporting traffic volume measurement information to support enhanced uplink data transmissions

[0001] The present invention relates to a wireless system comprising a wireless transmit / receive (WTRU) and a particular type node, the present invention relates to uplink (EU) traffic flow measurement information (TVM) to support EU data transmission between the WTRU and the node Node-B type via signaling channel with limited capacity.

BACKGROUND [0002] Methods for extending uplink (UL) coverage area, bandwidth and transmission delay in a wireless communication system such as a duplex frequency division system (FDD) are currently being investigated in version 6 (R6) of the Third Generation Partner Project ( 3GPP). Instead of scheduling and assigning uplink physical channels in the radio network controller (RNC), a Node-B node controller (i.e. base station) in such a way that more efficient decisions can be made, and uplink radio resources can be managed on a short-term basis better than an RNC controller, even if the RNC controller maintains total control over the system. A similar solution has already been adopted in the downlink for version 5 (R5) access with fast data packet transmission (HSDPA) in the universal mobile telecommunications system (UMTS) for both FDD mode and time division duplex (TDD) mode.

[0003] In order for a Node-B node to make effective decisions regarding the allocation and prioritization between flows of different priorities, the Node-B node must track the TVM measurement along with the associated priority. However,

Conventional UL signaling methods have limited capabilities and thus may not be able to cover TVM measurement reporting with associated priorities.

WTRU unit buffer. The WTRU sends the initial TVM measurement information request message to the Node-B node indicating that the WTRU has EU data to send to the Node-B. In response to receiving the initial TVM measurement request information message, the Node-B node schedules one or more allowed UE data transmissions between the WTRU and the Node-B node by sending the EU data link scheduling message to the WTRU.

[0006] The WTRU sends all EU data stored in the buffer to the Node-B if the allowed EU data transmissions are sufficient to support the transmission of all EU data stored in the Node-B

Buffer. Otherwise, the WTRU may send detailed TVM measurement information multiplexed with at least part of the EU data to the Node-B type node.

[0007] TVM measurement information may indicate the amount of EU data stored. Detailed TVM measurement information may indicate the amount of buffered EU data associated with each of the many traffic priority classes. Detailed information about the TVM measurement can be multiplexed in layer 2 of the media access control unit (MAC) or in layer 3 of radio resource control (RRC) or other equivalent layer 3 of the signaling unit.

[0008] The procedure used to transfer EU link data stored in the WTRU entity buffer may depend on whether or not the amount of EU link data exceeds a predetermined threshold. The initial TVM measurement request information message may be sent to a Node-B node only after the amount of EU data stored exceeds the established threshold. When the threshold set is not exceeded, the WTRU may send all EU data from the WTRU buffer to the Node-B node without having to schedule information from the Node-B node. If the threshold set is set to zero, the WTRU may send stored EU data from the WTRU entity buffer to the Node-B node only after receiving the scheduling information from the Node-B node.

[0010] Figure 1 shows a wireless communication system operating in accordance with the present invention;

[0011] Figure 2 is a signal flow diagram for the system of Figure 1 when more than one UE link transmission is necessary to transmit all UE data buffered in the WTRU;

[0012] Figure 3 is a signal flow diagram for the system of Figure 1 when only one UE link transmission is necessary to transmit all UE data buffered in the WTRU; and [0013] Figure 4 is a flowchart of a process comprising method steps for implementing TVM measurement reporting in accordance with the present invention.

DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT (EXAMPLES) [0014] In the following, the term "WTRU unit" includes user equipment (UE), a mobile station, a stationary or mobile subscriber unit, a pager or any other type of device capable of operating in a wireless environment, but not is limited to those listed.

[0015] When reference is made to the term "Node-B node" in the description below, it includes a base station, site controller, access point or any other type of device providing connection in a wireless environment, but is not limited to those listed.

[0016] The present invention may further be used in TDD, FDD mode, as well as in time-synchronous code-sharing multi-access method (TD-SCDMA), in use for UMTS, CDMA 2000 and CDMA in general, but it is envisaged also use in other wireless systems.

[0017] The features of the present invention may be included in an IC or be configured in a system comprising a plurality of interconnected components.

[0018] Figure 1 shows a wireless communication system 100 operating in accordance with the present invention. System 100 includes a WTRU 105 unit and a Node-B 110 node that communicate with each other via wireless signals 115. The WTRU 105 unit includes at least one buffer 120.

[0019] Figure 2 is a signal flow diagram of a wireless communication system 100 when EU data transmissions allowed by the first EU data scheduling message are not sufficient to transmit all EU data stored in buffer 120 of WTRU 105. EU data 205 is generated in the WTRU 105 unit and stored in the buffer 120 of the WTRU 105 unit. When the amount of EU data in the buffer 120 exceeds the established threshold value of the EU data buffer, then the WTRU 105 sends the initial TVM initial information request message 210 to the Node-B 110 through the EU link signaling channel. Due to the limited content transfer capacity on the EU signaling channel, detailed TVM measurement information cannot be included in the initial message 210 request initial information about the Initial TVM measurement message may after the TVM measurement information about

210 initial requests simply indicate that the WTRU 105 has EU link data ready to be sent,

<td> [0020]</td><td>They refer c</td><td>himself</td>

still to figure 2, after receiving the initial TVM measurement information request message 210, the Node-B 110 schedules one or more EU link transmissions between the WTRU 105 and the Node-B 110 via the first scheduling message 215 EU link data. In response to receiving the first EU 215 data scheduling message,

The WTRU 105 performs one or more EU data transmissions 220 to a Node-B 110 allowed by the first EU data scheduling message 215. If the EU data transmissions arranged by the Node-B 110 node are not sufficient to transmit all EU data buffered in the WTRU 105, then the WTRU 105 performs EU data transmissions 220 containing detailed TVM measurement information that indicates approximate amount of data buffered in the WTRU 105 unit. Optionally, detailed TVM measurement information may indicate the amount of buffered data associated with each assigned traffic priority class or logical channel mapped to a dedicated EU link channel (EU-DCH). Detailed information about the TVM measurement can be multiplexed in layer 2 or layer 3 with EU link data. In Layer 2, detailed TVM measurement information can be identified in the EU-DCH MAC header, and in Layer 3, detailed TVM measurement information can be signaled as part of Radio Resource Control (RRC) or another equivalent Layer 3 signaling unit. Link data 220 transmissions The EU may contain several independent physical transmissions.

[0021] The Node-B 110 may use full knowledge of TVM measurement information and potentially assigned priorities and / or logical channels reported via EU data transmission 220 in subsequent uplink scheduling. When the WTRU 105 obtains additional EU data at a later time, then the WTRU 105 may choose to report updated TVM measurement information to the NodeB 110 node. The Node-B 110 node then schedules subsequent EU link data transmissions from the WTRU 105 to the Node-B 110 node by consecutive EU link data scheduling messages 225a to 225n.

[0022] Figure 3 is a signal flow diagram of a wireless communication system 100 when one or more EU data transmissions allowed by an EU data scheduling message are sufficient to send all EU data stored in buffer 120 in the WTRU 105 EU link data 305 is generated in the WTRU 105 and is stored in buffer 120 of the WTRU 105. When the amount of EU data in buffer 120 exceeds the established EU data buffer threshold, then the WTRU 105 sends the initial TVM measurement information request message 310 to the Node-B 110 via the EU link signaling channel.

[0023] EU data transmissions sent by WTRU 105 need not be serialized by a Node-B 110 when the established EU data buffer threshold is not exceeded.

[0024] Referring still to Figure 3, after receiving the initial TVM measurement request information message 310, the Node-B node schedules one or more EU data transmissions between the WTRU 105 and the Node-B node using the message 315 scheduling of EU link data. In response to receiving the EU data scheduling message 315, the WTRU 105 performs one or more EU 320 data transmissions allowed by the EU data scheduling message 315. If the EU link transmissions allowed by the EU link data scheduler 315 are sufficient to send all EU data buffered in the WTRU 105, then all EU data stored in the buffer 120 of the WTRU 105 is sent to a Node-B. There is no need for additional TVM measurement reporting because the WTRU 105 is aware that there is no additional EU link data to be sent to the Node-B 110.

53 / 59P32763EN00 [0025]

Priority class-related data or logical channels / MAC-d flows associated with TVM measurements can be stored for precise use at the Node-B 110 allocation node for more channel and more efficient radio resources. The Node-B 110 uses TVM measurements and associated priorities to establish subsequent scheduling of EU data with greater accuracy due to the additional TVM measurement details provided by the WTRU 105.

[0026] Figure 4 is a flowchart of a process 400 comprising the steps of a method for transmitting user data from the WTRU 105 to a Node-B 110 in accordance with the present invention. In step 405, EU data is generated and stored in buffer 120 of WTRU 105 unit. In optional step 410, it is determined whether or not the amount of EU data stored in buffer 120 of WTRU 105 exceeds the established EU data buffer threshold. When the amount of EU data stored in buffer 120 of WTRU 105 does not exceed the set threshold, EU transmissions are allowed without scheduling the Node-B node, and all stored EU data is transmitted to the Node-B 110 (step 430). If the amount of EU data stored exceeds the set threshold, then the WTRU 105 sends the initial TVM measurement information request message to the Node-B 110 indicating that the WTRU 105 has EU data to be sent to the Node-B 110 ( step 415).

[0027] It should be noted that the established EU data buffer threshold may be set to zero. In this case, storing any amount of EU data in buffer 120 of WTRU 105 will always result in sending the initial TVM information request message 210.

[0028] Referring still to figure 4, in step

420, the Node-B 110 sends an EU data scheduling message containing information about one or more allowed EU data transmissions to the WTRU 105 to schedule EU data buffered in the WTRU 105 to a Node-B node 110. In step 425, the WTRU unit 105 determines whether the allowed EU data transmissions are sufficient to send all buffered EU data. If the EU data transmissions allowed by the scheduling are sufficient for all EU data stored in buffer 120, then all EU data buffered in the WTRU 105 are sent to the Node-B 110 in the allowed EU data transmissions (step 430).

[0029] If the EU data transmissions allowed by the current scheduling information are not sufficient to send all EU data buffered in the WTRU 105, then the WTRU 105 performs one or more transmissions containing detailed information multiplexed with part of the stored EU data, to a Node-B 110 node (step 435). At step 440, the Node-B 110 schedules and performs one or more additional EU data transmissions until more EU buffered EU data remains in the WTRU 105.

[0030] Although the present invention has been illustrated and described particularly with reference to preferred embodiments, it will be understood by the art that form and detail can be made without departing from the above described invention.
