Example Embodiment

[0047] In the existing solution, the base station only allocates transmission resources to the transmitting UE once in one SC period, or only allows the transmitting UE to automatically select transmission resources once. The transmitting UE can only send direct services to one target group in one SC period (the times of sending direct data may be multiple times, but the data transmitted in one SC period are the same). When the transmitting UE acts as a relay, in one SC period, it can only send direct services to one target group to serve one target group. That is, in the process of transmitting direct services to one target group, the transmitting UE cannot transmit direct services to other target groups. When there are many target groups for transmitting services required by the UE, direct services can only be sent to different target groups in different SC cycles in a certain order, and the delay of the direct services of the target group in the lower order is longer.

Abstract

The invention provides a direct service handling method and device of a user terminal. The method comprises the steps that when the number of target groups to be served simultaneously is N, a resource allocation request is sent to a base station; M resource pools issued by the base station and used for scheduling a resource distribution method and temporary identifiers allocated for the user terminal by the base station are received, wherein the temporary identifiers correspond to the M resource pools; when downlink control signals are received, time-frequency resource position information in the downlink control signals is obtained; according to the time-frequency resource position information, M time-frequency resources for transmitting direct services are determined respectively in the M resource pools; the obtained M resource pools are respectively allocated to the direct services corresponding to M target groups. By adopting the method and device, the user terminal can transmit direct services to other target groups in the process of transmitting the 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...
