Abstract

Provided are a resource allocation method and device, the resource allocation method comprising: receiving a switching command message sent by a source base station, the switching command message being used for indicating a terminal device that is performing direct communication to perform DAPS switching; before the terminal equipment successfully accesses the target base station, first schedulinginformation sent by the source base station is received, and the first scheduling information is used for indicating transmission resources configured by the source base station for the terminal equipment and used for direct communication; and after the terminal equipment successfully accesses the target base station, receiving second scheduling information sent by the target base station, the second scheduling information being used for indicating transmission resources configured by the target base station for the terminal equipment and used for direct communication. According to the invention, the terminal device obtains the transmission resources for direct communication by adopting the scheduling resource allocation mode in the DAPS switching process.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a resource configuration method and device. Background technique [0002] With the development of communication technology, direct communication technology has been proposed in recent years. Direct communication adopts terminal-to-terminal direct communication, which has high spectral efficiency and low transmission delay. For example, in a Long Term Evolution (Long Term Evolution, LTE) system and a 5G (New Radio, NR) system, multiple terminal devices can communicate directly through a PC5 interface. [0003] Direct communication includes two resource allocation methods, one is a scheduling resource allocation method, and the other is an automatic resource selection method. The scheduling resource allocation mode refers to that the base station schedules resources for the direct communication for the terminal equipment of the direct com...
