Problems solved by technology

[0005] In the multi-site cooperative transmission scenario, even if the PI field is introduced, in many specific scenarios, the UE still cannot determine the transmission behavior of the network side, so it often misjudges whether the time-frequency resources for multiple TRPs to send downlink data are preempted
Therefore, the data demodulation performance of the UE is still low

Abstract

The present application provides a method and device for receiving data, which can improve the data demodulation performance of terminal equipment. The method includes: the terminal device receives first resource indication information, and the first resource indication information is used to indicate information that the time-frequency resource occupied by each codeword in at least one codeword is preempted; the terminal device processes according to the first resource indication information Each of the at least one codeword.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and more specifically, to a method and device for receiving data. Background technique [0002] In new radio (NR), ultra-reliable low-latency communications (URLLC) have high requirements for low latency. From the network side, the network device dynamically allocates time-frequency resources of the network to URLLC users and enhanced mobile broadband (eMBB) users in real time according to its own scheduling situation and the needs of users it serves. That is, for a certain time-frequency resource of the network, it can be allocated to either URLLC users or eMBB users, mainly depending on user requirements and base station scheduling. [0003] However, after the base station allocates a certain time-frequency resource to an eMBB user, it may receive a scheduling request from the URLLC user. Due to the URLLC user's requirement for low latency, the base station may tempora...
