Abstract

The invention discloses a hybrid automatic repeat request feedback method, which comprises the following steps that: in an HARQ-ACK codebook, HARQ-ACK information of M PDSCHs (Physical Downlink SharedChannel) is contained, the M PDSCHs are scheduled by a first type of PDCCHs, and the first type of PDCCHs are used for activating SPS configuration; the sequence of the HARQ-ACK information of the MPDSCHs in the HARQ-ACK codebook is arranged according to at least one parameter value in a cell index, a BWP index, an SPS configuration index and a PDSCH transmission moment where the M PDSCHs are located respectively. The embodiment of the invention also comprises a hybrid automatic repeat request feedback method under the participation of the second type of PDCCH for releasing the SPS and the dynamically configured third type of PDCCH. The invention further comprises terminal equipment and network equipment which apply the method. According to the method and the device, the problem of how to generate the HARQ-ACK codebook when multiple PDSCHs are configured under the SPS configuration condition is solved.

Description

technical field [0001] The present application relates to the technical field of mobile communication, and in particular to a codebook generation method and device for multiple semi-persistently scheduled hybrid automatic repeat request responses. Background technique [0002] During dynamic scheduling, a network device (such as a base station) sends a physical downlink control channel (PDCCH) to a terminal device (UE) every time it schedules a PDSCH or PUSCH; semi-persistent scheduling (SPS, Semi-Persistent Scheduling) transmits a physical downlink control channel (PDCCH) by sending a physical downlink control channel , the network device periodically allocates PDSCH or PUSCH resources to the terminal device. Every time a cycle (for example, 10 ms) passes, the terminal device uses the SPS resource to receive or send data. [0003] The SPS configuration information is configured by the network device to the terminal device through RRC signaling. After the terminal device r...
