Embodiment 1

[0052] A HARQ feedback region is divided into multiple HARQ feedback channel transmission resource blocks, this embodiment uses figure 2 The shown HARQ feedback area composed of one LRU is taken as an example for illustration. specifically, Figure 4 will be figure 2 The shown PRU is divided into a schematic diagram of multiple HARQ feedback channel transmission resource blocks, as shown in Figure 4 As shown, each Tile included in the physical resource block is divided into two parts on average, each part is a SubTile, and each SubTile occupies 3 consecutive symbols in the time domain and 9 consecutive subcarriers in the frequency domain, Then divide the 4 SubTiles contained in an LRU into two equally, and pass SubTile1 and SubTile4 as the first part to form a HARQ feedback channel transmission resource block 1, while transmission resource block 2 and transmission resource block 3 constitute another HARQ feedback channel Transmission resource block 2.

Abstract

The invention discloses a realizing method, a dividing method and a multiplexing method of a feedback channel. The realizing method of the feedback channel comprises the following steps: dividing an uplink HARQ feedback area into HARQ feedback channel transmission resource blocks with the number of N according to a predetermined rule, wherein the uplink HARQ feedback area consists of M logic resource blocks, wherein both N and M are natural number; and each HARQ feedback transmission resource block multiplexes HARQ feedback channels with the number of R in the form of orthogonal code, wherein R is a natural number. By adopting the technical scheme, the uplink chain channel resource can be efficiently utilized, and the transmission performance of feedback information is ensured.

Description

technical field [0001] The invention relates to the communication field, in particular to a feedback channel realization method, division method and multiplexing method. Background technique [0002] Hybrid Automatic Repeat Request (HARQ for short) combines automatic repeat request technology (Automatic Repeat Request, short for ARQ) and forward error correction coding (Forward Error Correction, short for FEC) technology to detect errors and correct. For each HARQ data packet sent by the sending end, the receiving end performs verification after data demodulation and decoding. If the verification is correct, the receiving end will feed back a successful message (ACK) to the sending end, and the sending end will send a message to the receiving end. A new data packet; if the verification fails, the receiving end will feed back a message of failure to receive (NACK) to the sending end, and the sending end will retransmit the failed data packet according to the selected HARQ re...
