1. A method of transmitting uplink information, being applicable to user equipment of a new radio (NR) system, comprising:
obtaining uplink transmission configuration information sent by a base station, wherein the uplink transmission configuration information comprises at least: a time-frequency range of a target uplink resource which is an uplink transmission resource allocated by the base station for the user equipment in a target bandwidth part of an unlicensed spectrum;
determining channel detection information corresponding to the target uplink resource, wherein the channel detection information comprises: information corresponding to a valid resource and information corresponding to an invalid resource, the invalid resource is a resource in the target uplink resource which fails in channel detection; and the valid resource is a resource in the target uplink resource which succeeds in channel detection; and
in response to that the invalid resource exists in the target uplink resource, determining a mode for transmitting the uplink information on an available transmission resource according to the channel detection information;
wherein the uplink transmission configuration information further comprises: original transmission configuration information configured to inform the user equipment of the mode for uplink transmission;
wherein said determining the mode for transmitting the uplink information on the available transmission resource according to the channel detection information comprises:
adjusting uplink transmission parameters according to the channel detection information and the original transmission configuration information; and
transmitting the uplink information using the valid resource based on the adjusted uplink transmission parameters;
wherein the original transmission configuration information comprises: an original modulation-coding scheme corresponding to the target uplink resource;
wherein adjusting the uplink transmission parameters according to the channel detection information and the original transmission configuration information comprises:
determining a resource ratio of the invalid resource or the valid resource to the target uplink resource according to the channel detection information;
querying preset coding configuration information according to the resource ratio to determine a target variation corresponding to the resource ratio, wherein the preset coding configuration information comprises: a correspondence relationship between resource ratio and variation in the modulation-coding scheme; and
determining an adjusted modulation-coding scheme according to the original modulation-coding scheme and the target variation; and
wherein prior to querying the preset coding configuration information according to the resource ratio to determine the target variation corresponding to the resource ratio, the method further comprises:
obtaining the preset coding configuration information sent by the base station.
