Abstract

The present invention provides a transmission mode determination and information configuration method and equipment, the transmission mode determination method includes: determining the transmission mode of the physical downlink shared channel PDSCH scheduled by single downlink control information DCI according to the first preset information; wherein, the The first preset information is carried in at least one of the radio resource control RRC, the medium access control layer control element MAC CE and the DCI. The method disclosed in the invention can determine the PDSCH transmission mode, so that the PDSCH can be received correctly, thereby improving communication reliability.

Description

technical field [0001] The present invention relates to the technical field of communication, and more particularly relates to a method and device for determining a transmission mode and configuring information. Background technique [0002] High-frequency transmission is one of the characteristics of the fifth generation (5th generation, 5G) mobile communication system. However, the higher the transmission frequency used by network equipment, the more limited its coverage. Therefore, the concept of multiple transmission and reception points (Transmission Reception Point, TRP) is introduced in 5G, and a cell can contain multiple TRPs. Multiple TRPs can jointly send data to a terminal device (User Equipment, UE) to improve throughput or reliability. [0003] At present, it has been determined that the multi-TRP transmission scenario supports multiple transmission modes. For example, from the perspective of frequency domain resources used by multi-TRP transmission, multi-TR...
