RESOURCE ALLOCATION METHOD FOR D2D COMMUNICATIONS, BASE STATION USING THE SAME, AND USER EQUIPMENT USING THE SAME

摘要

A resource allocation method for device to device (D2D) communications and a base station using the same are provided. In the method, resource patterns are assigned, wherein each of the resource patterns comprises resource groups comprising the resource block(s). Frequency index and time index of each resource group in a time-frequency domain of resource pattern are determined, and there exists at least one of the resource patterns such that the time index of a first resource group and the time index of a second group are different. The resource groups of each resource pattern to the UEs are respectively assigned according to the frequency index and the time index of each of the resource groups in the time-frequency domain of each resource pattern.

1. A resource allocation method, used for a base station to assign resource blocks for device to device (D2D) communications of a plurality of user equipments (UEs), the method comprises:
assigning a plurality of resource patterns, wherein each of the plurality of resource patterns comprises resource groups, and each of the resource groups comprises the resource blocks; determining frequency index and time index of each of the resource groups in a time-frequency domain for each of the plurality of resource patterns, and there exists at least one of the plurality of resource patterns such that the time index of a first resource group and the time index of a second group are different; and assigning the resource groups of each of the plurality of resource patterns to the plurality of UEs respectively according to the frequency index and the time index of each of the resource groups in the time-frequency domain of each of the plurality of resource patterns.
