Embodiment Construction

[0047] In the existing solution, the base station only allocates a transmission resource for the transmitting UE once in one SC period, or only allows the transmitting UE to automatically select the transmission resource once. The transmitting UE can only send direct services to one target group in one SC period (the number of direct data transmissions can be multiple times, but the data transmitted in one SC period is the same). When the transmitting UE acts as a relay, within one SC period, it can only send direct services to one target group and serve one target group. That is, when the transmitting UE transmits the direct service to one target group, it cannot transmit the direct service to other target groups. When there are many target groups that the UE needs to serve, it can only send direct services to different target groups in different SC cycles in a certain order, and the delay of the direct services of the lower-ranked target groups is longer.

Abstract

A method and device for direct service processing of a user terminal, the method comprising: when the number of target groups to be served at the same time is N, sending a resource allocation request to a base station; M resource pools and temporary identities assigned by the base station to the user terminal, the temporary identities corresponding to the M resource pools; when receiving downlink control signaling, acquiring time-frequency resources in the downlink control signaling Location information; according to the time-frequency resource location information, respectively determine M time-frequency resources used to transmit direct services in the M resource pools; allocate the obtained M time-frequency resources to M target groups respectively Corresponding direct business. By adopting the method and device, the user terminal can transmit direct services to other target groups during the process of transmitting direct services to one target group.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a method and device for direct service processing of a user terminal. Background technique [0002] Device to Device (D2D) communication, also known as direct communication, can directly perform short-distance transmission between two peer devices under the control of the network without passing through the base station, allowing terminals to pass through The technology of multiplexing cell radio resources for direct communication; it can also be a technology for direct communication between two peer-to-peer devices using pre-configured radio resources without being under the control of the network. [0003] When user terminal A is within the coverage of the cell and user terminal B is at the edge of the cell or outside the coverage, user terminal A can communicate with the base station through the Uu interface, and can communicate with user terminal B through the PC...
