Abstract

The invention provides an upstream scheduling method and an upstream scheduling device. The method comprises the steps as follows: user equipment (UE) receives downstream control information (DCI) sent by a base station, and the UE transmits an upstream channel or/and a signal according to configuration information of the base station and the DCI channel and determines the transmission power of the channel and/or the signal. According to the technical scheme of the method and the device provided by the invention, the problems of license information confirmation and transmission power distribution and indication are solved, and a technical scheme of licensed carrier assisted access is completed.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for uplink scheduling. Background technique [0002] In related technologies, the 3rd Generation Partnership Project (the 3rd Generation Partnership Project, referred to as 3GPP) has completed the downlink communication (base station transmission; user equipment (User Equipment) Equipment, referred to as the standardization work of the UE (receiving) part. In the next period of time, 3GPP will carry out the standardization work of the uplink communication (UE transmission; base station reception) part of LAA. [0003] In LAA uplink communication, before the UE transmits data (including channels and signals here), it needs to obtain authorization (or configuration) from the base station. However, the content of the authorization information has not been determined in the related art. [0004] When the UE transmits data, there may be licensed carriers or un...
