Embodiment 1

[0058] This embodiment considers the frame structure of the FDD system. For the FDD system, any uplink subframe in the frame structure can feed back channel information. Such as Figure 7 As shown, the network side configures the feedback cycle of the UE to be 10 milliseconds through high-level signaling, and the PHY layer (Physical layer, physical layer) of the UE performs channel information measurement in subframe n and reports the measurement result to the MAC layer of the UE. In the uplink subframe n-k of each frame, BSR is sent. In this embodiment, n selects 8, k selects 4, that is, the PHY layer of the UE performs channel information measurement in subframe 8 and reports the measurement result to the MAC layer of the UE, and the UE The BSR is sent in the uplink subframe 4 of each frame. The type of the BSR is determined according to the state of the buffer area. If the buffer area at subframe 4 has only one logical channel group data and channel state information data t...

Embodiment 2

[0062] This embodiment considers the frame structure of the TDD system. For the TDD system, it supports uplink and downlink subframe switching periods of 5 milliseconds and 10 milliseconds. The TDD system includes 7 subframe configuration modes, and the subframe configuration mode 1 is now used, such as Figure 8 As shown, to illustrate the specific implementation process of the present invention, other subframe configuration modes have similar processes. The network side configures the UE's feedback cycle to be 10 milliseconds through high-level signaling, and the PHY layer of the UE performs channel information measurement and reports the measurement structure to the MAC layer of the UE. The UE determines according to the feedback mode and the number of cells that need to feedback the channel state The size of the feedback amount, in the uplink subframe 3, decides which type of BSR to send according to the state of the buffer area. If there is only one logical channel group d...

Abstract

Provided is a method for feeding back a buffer status report BSR, comprising: configuring, by a network side, a UE in an explicit feedback mode, completing measurement of channel information on a physical layer of the UE, and sending a measurement result to a MAC layer; and reporting, by the UE, a BSR to the network side according to logic channel data volume. A device for feeding back a buffer status report BSR is further provided. According to the technical solutions of the present invention, the problem of feedback data buffer report in the process of explicit feedback of UE BSR can be solved, so as to ensure the uplink resource authorization in feedback of UE.

Description

technical field [0001] The present invention relates to a wireless communication system, in particular to a UE (User equipment) buffer state report BSR feedback method and device in an LTE-A (Long Term Evolution-Advance, Advanced Long Term Evolution) system. Background technique [0002] CoMP (Coordinated multipoint transmission, Coordinated Multipoint Transmission) technology is to use the transmit antennas of multiple cells to coordinate transmission to achieve higher capacity and reliable transmission of wireless links at the edge of the cell, which can effectively solve the problem of interference at the edge of the cell. [0003] CoMP technology can be divided into two categories: JP (Joint Process, joint processing) and CS / CB (Coordinated scheduling / Coordinated Beamforming, joint scheduling or joint beamforming), and both types of coordinated multi-point technologies require UE feedback channels status information to support. [0004] In the current 3GPP meeting, the ...
