Abstract

Provided in an embodiment of the present invention are a HARQ-ACK feedback mode determination method, configuration method and device, the method comprising the steps of: determining a HARQ-ACK feedback mode corresponding to a PDSCH according to a service type corresponding to the PDSCH; or, according to a radio network temporary identifier (RNTI) of the PDSCH, determining an HARQ-ACK feedback mode corresponding to the PDSCH; or, according to downlink control information (DCI) for scheduling the PDSCH, determining an HARQ-ACK feedback mode corresponding to the PDSCH. In the embodiment of the invention, the network side equipment configures the corresponding HARQ-ACK feedback mode for the PDSCH scrambled by each service type or each RNTI, or the network side equipment indicates the HARQ-ACK feedback mode through DCI, so that different services with different requirements can be configured with different HARQ-ACK feedback modes, and uplink feedback resources are saved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a HARQ-ACK feedback mode determination method, configuration method and equipment. Background technique [0002] In long term evolution (Long Term Evolution, LTE) broadcast multicast transmission, multicast / multicast single frequency network (Multicast Broadcast Single Frequency Network, MBSFN) mode Multimedia Broadcast / Multicast Service (Multimedia Broadcast / Multicast Service, MBMS) transmission and single cell point to multipoint transmission (Single Cell-Point To Multipoint, SC-PTM) mode of multicast service transmission. In the MBSFN mode, the cells in the same MBSFN area will send the same broadcast service synchronously, which is convenient for the terminal to receive. MBMS service control information (control channel parameters, traffic channel parameters, scheduling information, etc.) and data information are sent in broadcast mode, so that both idle state...
