Problems solved by technology

[0007] When a single physical downlink control channel and multiple TRPs are used to perform URLLC services, the FDM solution needs to use one PDCCH to schedule the PDSCHs sent by multiple TRPs, that is, one DCI carries the PDSCH resource allocation of two TRPs, which cannot be realized by existing technologies. additional design is required

Abstract

The embodiment of the invention provides a resource allocation method, a resource determination method, network equipment and a terminal. The resource allocation method comprises the following steps: downlink control information (DCI) is sent to a terminal, the DCI carries first indication information and second indication information, the first indication information is used for indicating M modulation and coding strategies (MCS), the second indication information is used for indicating all frequency domain resources used by one or M physical downlink shared channels (PDSCH), m is an integer greater than or equal to 1. According to the scheme of the invention, the DCI overhead is effectively reduced; and the spectrum efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of communication, and in particular to a resource allocation method, a resource determination method, network equipment and a terminal. Background technique [0002] In order to improve the reliability of URLLC (high reliability and low delay service) transmission, it supports multi-TRP (multi-transmission receiving point) transmission, that is, multiple TRPs transmit the same data packet to obtain additional power gain. When using multiple TRPs to transmit URLLC services, there are three schemes: SDM (Space Division Multiplexing), FDM (Frequency Division Multiplexing), and TDM (Time Division Multiplexing). backhaul (creative-backhaul); only one TRP sends PDCCH (Physical Downlink Control Channel); multiple TRPs send PDSCH (Physical Downlink Shared Channel), and the PDSCHs of multiple TRPs use the same DMRS (modulation and demodulation reference signal ) ports, the same time-domain resources, but occ...
