Abstract

The invention discloses an SPS PDSCH type indication method and device, a terminal and network side equipment, and belongs to the technical field of wireless communication. The method for indicating the type of the SPS PDSCH comprises the following steps: network side equipment indicates the type of the SPS PDSCH to a terminal, and the type comprises a multicast SPS PDSCH used for multicast transmission or a unicast SPS PDSCH used for unicast transmission.

Description

technical field [0001] The present application belongs to the technical field of wireless communication, and in particular relates to an SPS PDSCH type indication method, device, terminal and network side equipment. Background technique [0002] For semi-persistent scheduling (Semi-Persistent Scheduling, SPS) physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) transmission, the high layer configures some parameters of the downlink (Down Link, DL) SPS, and uses the downlink control information (Downlink Control Information , DCI) is activated, after the downlink SPS transmission is activated, the PDSCH transmission is initiated periodically, and there is no corresponding DCI indication for these PDSCH transmissions. [0003] The terminal can configure one or more DL SPSs on one or more serving cells, each DL SPS corresponds to a configuration index, and the period of each SPS PDSCH can be as small as 1 time slot. Multiple simultaneously active DLSPS co...
