Abstract

The present application discloses a method and device for sending hybrid automatic repeat response information. The method includes the following steps: activating N sets of SPS configurations, N≥1; the HARQ-ACK information corresponding to the SPS configuration only includes targets within a set period of time HARQ-ACK information of PDSCH, the set period satisfies: each set of the N sets of SPS configurations includes at least one PDSCH within the set period; the PDSCH within the set period, the corresponding HARQ The ACK feedback time is within a set target time unit; the target PDSCH is the PDSCH of the P sets of SPS configurations that are signaled within the set period, P<N. The present application also includes terminal equipment, network equipment and systems applying the method. The method and system of the present application solve the problems of low transmit power efficiency of the prior art terminal device and low overall system efficiency when the terminal device configures and activates multiple sets of SPS.

Description

technical field [0001] The present application relates to the field of mobile communication technologies, and in particular, to a method and device for transmitting hybrid automatic repeat response information. Background technique [0002] Semi-persistent scheduling (SPS) or semi-persistent scheduling, through one downlink control signaling (PDCCH), periodically allocates multiple PDSCH resources to specific terminal equipment. The specific process is that the base station configures SPS resources for the terminal device through RRC signaling; after the terminal device receives the SPS configuration information, it also needs to receive the PDCCH that activates the SPS configuration; after the SPS configuration is activated, the terminal device will be instructed by the PDCCH every time a cycle elapses. The base station does not need to issue the PDCCH to designate the allocated resources. Since the SPS scheduling has the characteristic of "once allocation, multiple use", ...
