Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] The present invention proposes a method for transmitting ACK / NACK information on PUSCH, including:

[0036] The base station allocates PUSCH resources for the UE, and sends the scheduling information of the PUSCH resources through the PDCCH;

[0037] The UE determines the number of bits of ACK / NACK information according to the UL DAI in the PDCCH and selects an encoding method, and uses the encoding method to encode the ACK / NACK information; selects according to the ACK / NACK transmission mode configured by the UE in single Cell mode Scrambling and scrambling the ACK / NACK information after the encoding operation;

[0038] The UE transmits the ACK / NACK information after the scrambling operation on the PUSCH.

[0039]In the above method, whe...

Abstract

The invention provides a method for transmission of ACK (acknowledgement) / NACK (negative acknowledgement) information on a PUSCH (physical uplink shared channel). The method includes: a base station distributes PUSCH resources for UE (user equipment) and sends scheduling information of PUSCH resources through a PDCCH (physical downlink control channel); the UE determines the bit number of the ACK / NACK information and selects a coding method according to UL (uplink) DAI (downlink allocation indication) in the PDCCH and subjects the ACK / NACK information to coding operation by the coding method; scrambling codes are selected according to an ACK / NACK transmission mode configured by the UE in a Cell mode, and the ACK / NACK information subjected to coding operation is subjected to scrambling operation; and the UE transmits the ACK / NACK information subjected to scrambling operation on the PUSCH. Using the method enables effective ACK / NACK information as much as possible to be sent on the PUSCH by means of 4-bit feedback capacity, and mixing of the ACK / NACK information by the base station can be eliminated during CA (carrier aggregation) and reconfiguration.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method for transmitting acknowledgment (ACK) / denial (NACK) information on a physical uplink shared channel (PUSCH). Background technique [0002] The Long Term Evolution (LTE) system performs data transmission based on Hybrid Automatic Repeat Request (HARQ), that is, according to the reception status of the data, the data receiver will correspondingly send ACK or NACK reception status feedback information. The scheduling information of dynamic downlink data transmission is transmitted through the physical downlink control channel (PDCCH). For semi-persistent scheduling (SPS) services, the initial transmission scheduling information of downlink data does not need to be sent on the PDCCH, and it is only passed when the downlink data is retransmitted. The PDCCH transmits scheduling information. [0003] For the LTE TDD system, in order to enable the user eq...
