Problems solved by technology

However, when the network device transmits PUSCH through the third piece of information (Message 3, MSG.3) in the contention-based random access process scheduled by DCI format 0_0 or the uplink single-antenna port transmits PUSCH, the terminal device sends the DCI-scheduled PUSCH The Sounding Reference Signal (SRS) may not be sent before, and the uplink beam management (used to determine the uplink transmission beam) may not be performed. At this time, the terminal device cannot determine the transmission beam of the PUSCH transmission

Abstract

The embodiment of the invention provides a physical uplink shared channel transmission method and terminal equipment. Therefore, when a terminal does not perform uplink beam management before being scheduled to transmit a PUSCH and cannot determine the uplink beam, a sending beam for transmitting the PUSCH can be determined, so that the PUSCH can be transmitted according to the determined beam, and the performance of PUSCH transmission is improved. The method comprises the following steps that: the terminal equipment determines the sending beam for transmitting a first PUSCH according to a beam for receiving a PDCCH, or according to a previously sent beam adopted by the PUSCH, or according to a beam adopted by the PUCCH; and the terminal equipment transmits the first PUSCH according to thedetermined beam.

Description

[0001] This application is a divisional application of an application with an application date of February 14, 2018, an application number of 201880042527.7 (international application number of PCT / CN2018 / 076874), and an invention title of "Physical Uplink Shared Channel Transmission Method and Terminal Equipment". technical field [0002] The present application relates to the communication field, and more specifically, to a physical uplink shared channel transmission method and terminal equipment. Background technique [0003] In the fifth-generation mobile communication technology new air interface (5-Generation New Radio, 5G NR), network equipment can pass two downlink control information (Downlink Control Information, DCI) formats (format) (for example, DCI format 0_0 and DCI format 0_1 ) to schedule physical uplink shared channel (Physical Uplink Shared Channel, PUSCH) transmission. However, when the network device transmits PUSCH through the third piece of information...
