Problems solved by technology

[0004] However, no matter in synchronous uplink HARQ or asynchronous uplink HARQ, the base station does not distinguish between uE identification information and data when performing uplink transmission information feedback, and in the current uplink transmission information feedback method, the base station sends Feedback, which leads to low efficiency of uplink transmission information feedback, and cannot support uplink transmission without authorization (Grant-free)

Abstract

Embodiments of the present invention provide a transmission method, a base station and a mobile station used in uplink hybrid automatic repeat (HARQ). The transmission method used in uplink hybrid automatic repeat (HARQ) applied to the base station includes: receiving uplink transmission information sent from one or more terminal equipments (UEs), wherein the uplink transmission information sent by each UE includes the UE's uplink transmission information. identification information and data information; detect the identification information of the one or more UEs according to the uplink transmission information; when there is identification information that cannot be correctly detected according to the uplink transmission information, send a The UE sends a common failure acknowledgement signal.

Description

technical field [0001] The present invention relates to the field of wireless communication, and in particular to a transmission method, a base station and a mobile station used in Uplink Hybrid Automatic Repeat (HARQ) that can be used in a wireless communication system. Background technique [0002] In the traditional uplink hybrid automatic repeat (HARQ), when the base station does not correctly receive the uplink transmission information sent by the terminal equipment (UE), the UE retransmits the uplink transmission information at fixed time intervals, that is, the uE retransmits the uplink transmission information in a synchronized manner. Retransmission of uplink transmission information is carried out in a way. However, when there are multiple uEs at the same time, if uplink HARQ is performed in a synchronous manner, since the transmission interval is the same, it is easy to cause collisions between uplink transmission information of each uE. [0003] Asynchronous upl...
