Abstract

The method and device for sending a physical uplink shared channel disclosed in the present application relate to the field of communications, and solve the problem of how to use different precoding matrices to transmit uplink data to different TRPs. The network device sends indication information to the terminal device, where the indication information is used to indicate the first information and the second information. The first information is used to indicate the first precoding information corresponding to the first nominal PUSCH replica. The second information is used to indicate second precoding information corresponding to the second nominal PUSCH replica. The terminal device sends N PUSCHs according to the precoding information indicated by the indication information. The precoding information corresponding to the N PUSCHs includes at least one of first precoding information and second precoding information.

Description

technical field [0001] The embodiments of the present application relate to the field of communications, and in particular, to a method and an apparatus for sending a physical uplink shared channel. Background technique [0002] The International Telecommunication Union (ITU) defines three types of service application scenarios for the fifth generation (5G) mobile communication system and future mobile communication systems: enhanced mobile broadband (eMBB), Highly reliable and low latency communications (ultrareliable and low latency communications, URLLC), massive machine type communications (massive machine type communications, mMTC). [0003] Generally, before sending a physical uplink shared channel (PUSCH) to a network device, a terminal device precodes user bits according to a precoding matrix indicated by the network device to obtain uplink data, and then sends a PUSCH carrying the uplink data. Generally, the network device indicates a precoding matrix through downl...
