System and Method for Communicating Resource Allocation for D2D

摘要

When the frequency resource allocation is conveyed on a bandwidth that is different from a bandwidth on which the frequency resource allocation is sent, a receiving D2D UE needs to understand the resource allocations. A resource allocation method for device-to-device resource allocation is provided according to an example. The resource allocation method includes a first D2D user equipment (UE) receiving a downlink control information (DCI) from an access point, wherein the DCI comprises a first D2D frequency allocation and the first D2D frequency allocation comprises a first resource allocation field for transmission of data; setting a second resource allocation field of a second D2D frequency allocation of a sidelink control information (SCI) format according to the first resource allocation field; transmitting the SCI format to one or more additional D2D UEs; and transmitting the data on the resource according to the second D2D resource allocation.

1. A method for device-to-device (D2D) resource allocation, comprising:
receiving, by a first D2D user equipment (UE), a downlink control information (DCI) from an access point (AP), wherein the DCI comprises a first D2D frequency allocation and the first D2D frequency allocation comprises a first resource allocation field for transmission of data; setting, by the first D2D UE, a second resource allocation field of a second D2D frequency allocation of a sidelink control information (SCI) format according to the first resource allocation field; transmitting, by the first D2D UE, the SCI format to one or more additional D2D UEs; and transmitting, by the first D2D UE, the data according to the second D2D resource allocation.
