Description

Resource indication method, related equipment and computer readable storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to a resource indication method, a related device, and a computer-readable storage medium.

Background

In a New Radio (NR), a network device indicates information such as a corresponding frequency domain resource to a User Equipment (UE) through a Physical Downlink Control Channel (PDCCH), and the UE completes data reception on the corresponding frequency domain resource according to a frequency domain indication in the received PDCCH information. There are two types of allocation of frequency domain resources, which are resource allocation type 0 and resource allocation type 1, respectively. In the prior art, for a Resource allocation type 0, a frequency domain Resource Indication field in Downlink Control Information (DCI) can only indicate one bitmap, and for a frequency domain Resource allocation type 1, a frequency domain Resource Indication field in DCI can only indicate one Resource Indication Value (RIV). If a coordinated multi-Transmission/reception point (TRP)/antenna array (panel) can use non-overlapping frequency domain resources to perform repeated Transmission for multiple times within a slot (slot) (the number of times is the number of coordinated TRPs/panels), in this case, the ue cannot determine the frequency domain resources used when each TRP in multiple TRPs performs Physical Downlink Shared Channel (PDSCH) Transmission according to a bitmap or an RIV.
