Abstract

The invention relates to a method for generating ACK / NACK information, which comprises the following steps that: the number of downlink resources for sending data to user equipment by a base station is N', N' pieces of ACK / NACK information exist aiming at the N' downlink resources, the number of ACK / NACK bits sent in an uplink subframe is M, and when N' is more than or equal to M, the N' downlinkresources after sending the data are divided into M groups, and each group of the downlink resources outputs one piece of ACK / NACK or DTX information in a binding mode; and the user equipment sends the ACK / NACK or DTX information in the uplink subframe. The method fully uses the capability of sending multi-bit ACK / NACK in the uplink direction, and can improve the downlink throughput.

Description

technical field

[0001] The present invention relates to a wireless communication system, more specifically to a method for generating ACK / NACK information in the wireless communication system. Background technique

[0002] The 3GPP standardization organization is conducting long-term evolution (LTE) of its existing system specifications. figure 1 It is the frame structure of the LTE TDD system. Each length is 307200×T s = The wireless frame of 10ms is equally divided into two lengths of 153600×T s = half frame of 5 ms. Each half frame contains 8 lengths of 15360T s = 0.5ms time slot and 3 special domains, namely downlink pilot time slot (DwPTS), guard interval (GP) and uplink pilot time slot (UpPTS), the sum of the length of these 3 special domains is 30720T s = 1 ms. Each subframe consists of two consecutive time slots, that is, the kth subframe includes time slot 2k and time slot 2k+1. Subframe 1 and subframe 6 include the above three special fields. For example, T...
