Embodiment 1

[0045] When the DL / UL subframe configuration of the cell is 4, as shown in Table 1, subframes #2 and #3 are uplink subframes, subframe #1 is a special subframe, #0, #4, #5, #6 , #7, #8, and #9 are downlink subframes. It can be seen from Table 3 that the PUCCHs of uplink subframes #2 and #3 need to send 4 downlink subframes PDSCH to receive related ACK / NACK respectively, that is, they need to pre-set Reserve 4 ACK / NACK resources. When the load of the cell is not high, or there are not many CCE groups of the PDCCH related to the PDSCH, most of the reserved resources will be wasted, and the uplink resources in this configuration are limited. At this time, it is necessary to reduce the PUCCH overhead through PUCCH compression , which can increase the capacity of the physical uplink shared channel.

[0046] Such as figure 2 As shown, the base station can control the PUCCH resources through the following steps:

[0047] Step 201, the base station notifies the UE in the cell of t...

Abstract

The invention discloses a method for notifying physical uplink control channel resource compression. Physical uplink control channel compression indication parameters are broadcast through system broadcasting messages. The physical uplink control channel compression indication is used for a base station to notify whether a terminal compresses affirmative or negative response resources used for reflecting a physical downlink shared channel receiving state on the physical uplink control channel or not. By the method, the base station can be only configured with a maximum physical uplink controlchannel resource, then controls whether to compress the physical uplink control channel or not and the compression level according to the specific condition of a cell and effectively notifies the information to the terminal, so the base station has the capacity of coordinating the expense of the physical uplink control channel resource and the flexibility of a dispatcher to improve the operation efficiency of the system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for notifying PUCCH (Physical Uplink Control Channel, Physical Uplink Control Channel) resource compression. Background technique [0002] In the HARQ (Hybrid Automatic Repeat Request, Hybrid Automatic Repeat Request) mode, the code sent by the originating end can not only detect errors, but also have certain error correction capabilities. After receiving the code word, the decoder at the receiving end first checks the error situation. If it is within the error correction capability of the code, it will automatically correct the error. If there are many errors that exceed the error correction capability of the code, but it can detect errors, then The receiving end sends a decision signal to the sending end through the feedback channel, requesting the sending end to resend the information. [0003] In the OFDM (Orthogonal Frequency Division Multiplex, Orthogonal Frequen...
