Title:
PHYSICAL UPLINK SHARED CHANNEL TRANSMISSION METHOD AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/157733
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a physical uplink shared channel transmission method and a terminal device. With said method, when a terminal does not carry out uplink beam management before being scheduled to transmit a PUSCH and is thus unable to determine an uplink beam, a transmission beam for transmitting the PUSCH may be determined, and the PUSCH may thus be transmitted according to the determined beam, thereby improving the PUSCH transmission performance. The method comprises: a terminal device determines a transmission beam for transmitting a first PUSCH according to a beam used to receive a PDCCH, a beam used to transmit a PUSCH previously or a beam used to transmit a PUCCH; and the terminal device transmits the first PUSCH according to the determined beam.
