Abstract

The invention discloses an uplink signal transmission method, terminal equipment and network equipment, which can realize correct transmission of UCI for demodulating uplink data on an unlicensed spectrum. The method comprises: the terminal equipment determines a first time-frequency resource and a second time-frequency resource, wherein the first time-frequency resource is used for transmitting uplink data obtained by rate matching of a first transmission block, the second time-frequency resource is used for transmitting uplink control information UCI, the UCI is used for demodulating the uplink data, the first time-frequency resource occupies N sub-bands on a frequency domain, the second time-frequency resource is a resource in the first time-frequency resource, the second time-frequency resource occupies M sub-bands in the N sub-bands on the frequency domain, N is greater than or equal to 2, M is greater than or equal to 1, and both N and M are positive integers; and the terminal equipment performs channel detection on at least one sub-band in the N sub-bands, and determines the sending of the uplink data and the UCI according to a detection result.

Description

[0001] This application is a divisional application of an application with an application date of June 26, 2019, an application number of 2019800428000, and the title of the invention is "An Uplink Signal Transmission Method, Terminal Equipment, and Network Equipment". technical field [0002] The embodiments of the present application relate to the field of communications technologies, and in particular, to a method for transmitting an uplink signal, a terminal device, and a network device. Background technique [0003] In a New Radio (New Radio, NR) system such as a 5G application, an unlicensed (unlicensed) spectrum may be used, that is, the NR technology is used for communication on a channel of the unlicensed spectrum. In order to allow various wireless communication systems that use unlicensed spectrum for wireless communication to coexist amicably on this spectrum, some countries or regions stipulate the regulatory requirements that must be met when using unlicensed sp...
