Title:
UPLINK SIGNAL TRANSMISSION METHOD, TERMINAL DEVICE, AND NETWORK DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/001484
Kind Code:
A1
Abstract:
An uplink signal transmission method, a terminal device, and a network device for achieving correct transmission of uplink control information (UCI) used to demodulate uplink data on an unlicensed spectrum. The method comprises: a terminal device determining a first time frequency resource and a second time frequency resource, the first time frequency resource being used to transmit uplink data acquired by a first transmission block performing rate matching, the second time frequency resource being used to transmit UCI, the UCI being used to demodulate the uplink data, the first time frequency resource occupying N sub-bands in a frequency domain, the second time frequency resource being a resource in the first time frequency resource, and the second time frequency resource occupying M sub-bands of the N sub-bands in the frequency domain, where N ≥ 2, M ≥ 1, and N and M are positive integers; and the terminal device performing channel detection on at least one of the N sub-bands, and determining the transmission of the uplink data and the UCI according to a detection result.
