Problems solved by technology

Since the UE's PUCCH transmission requirements change dynamically, different multiplexing situations need to be flexibly changed, but the existing technology is difficult to support this kind of scheduling, resulting in the UE's HARQ-ACK message transmission in different scenarios is not flexible enough

Embodiment 1

[0117] The base station notifies the UE of three candidate parameter configuration groups for HARQ-ACK transmission through high-level signaling, and each candidate parameter configuration includes the PUCCH resource starting position indication used for PUCCH Format1a / 1b transmission and the sequence ID X used to generate the HARQ-ACK transmission sequence; wherein, the corresponding relationship between the candidate parameter configuration group and the resource configuration signaling indication is shown in Table 2 below:

Embodiment 2

[0125] The base station notifies the UE of a HARQ-ACK transmission parameter configuration group (configuration group 1) through high-level signaling, including the PUCCH resource start position indicator used for PUCCH Format1a / 1b transmission and the sequence ID X used to generate the HARQ-ACK sequence; based on this parameter configuration group, the UE obtains other candidate parameter configuration groups (configuration groups 2 and 3) except the corresponding parameter configuration group (configuration group 4) of the serving cell configuration parameters, The method of obtaining is:

[0126] The HARQ-ACK resource configuration in configuration group 2 is obtained by the HARQ-ACK resource configuration in configuration group 1+1, and the sequence ID in configuration group 2 is the same as the ID in configuration group 1;

Embodiment 3

[0135]The base station notifies the UE of four candidate parameter configuration groups for HARQ-ACK transmission through high-level signaling, and each candidate parameter configuration includes the PUCCH resource indication used for PUCCH Format 3 transmission and the sequence ID X used to generate the HARQ-ACK transmission sequence; and the base station configures PUCCH resources for the HARQ-ACK transmission corresponding to the two antenna ports, but they use the same sequence ID. Among them, the corresponding relationship between candidate parameter configuration groups and resource configuration signaling indications is shown in Table 4 below:

Abstract

The invention discloses a transmission method for a HARQ-ACK message and a control method and device thereof, so transmission of the HARQ-ACK message through UE under different scenes is more flexibly achieved. The transmission method for the HARQ-ACK message includes the steps that the UE obtains indicating information sent by a base station and used for HARQ-ACK message transmission of a parameter configuration group, and the parameter configuration group comprises HARQ-ACK resource allocation used for HARQ-ACK message transmission and / or sequence ID configuration generating HARQ-ACK transmission sequences; the parameter configuration group used for the HARQ-ACK message transmission is determined through the UE according to the indicating information, and HARQ-ACK parameter configuration in the parameter configuration group is determined; the UE carries out HARQ-ACK message transmission according to the HARQ-ACK parameter configuration.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a transmission of HARQ-ACK message and its control method and device. Background technique [0002] In the existing Long Term Evolution-Advanced (LTE-A) system, in order to support more flexible transmission of Hybrid Automatic Repeat Request (Hybrid-ARQ, HARQ) acknowledgment (ACK) messages (referred to as HARQ-ACK messages), some enhancements can be considered To support inter-cell orthogonal HARQ-ACK transmission, or HARQ-ACK transmission with intra-cell interference randomization. At present, it is difficult for the existing technology to support flexible switching of UEs from different resources and different sequences in different multiplexing scenarios. [0003] The introduction of HARQ-ACK transmission is as follows: [0004] In the current standard, HARQ-ACK can be transmitted through several physical uplink control channel (PUCCH) formats (Format): PUCCH...
