Title:
UPLINK DATA SCHEDULING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/157754
Kind Code:
A1
Abstract:
Disclosed are an uplink data scheduling method and device, the method comprising: a terminal device receiving a first signalling sent by a network device, wherein the first signalling comprises beam information of M beams, and M is a positive integer; the terminal device carrying out carrier sensing on the M beams in sequence according to the first signalling; and the terminal device selecting, according to the sensing result, one beam of the M beams to transmit an uplink channel to the network device. Therefore, the network device configures a plurality of candidate beams for the terminal device for transmission of the uplink channel, so that the terminal device carries out carrier sensing on the plurality of candidate beams in sequence based on a certain rule, and selects, based on the sensing result, a suitable beam to transmit the uplink channel, thereby greatly reducing transmission time delay of the uplink channel on an unlicensed frequency band.
