Abstract: Aspects of the present disclosure provide a system, method, and apparatus for implementing an intelligent Dynamic Frequency Selection (DFS) procedure that avoids unnecessary scanning of an unlicensed or shared spectrum, and hence offers efficient power utilization for user equipments (UEs). In one aspect, one or more UEs may periodically identify at least one of a current operating frequency, a mode of operation, and the public land mobile network (PLMN) associated with the UE to determine whether the UE is operating in a DFS channel. Based on the above-identified factors, the UE may determine whether the UE is actively scheduling uplink data transmission on the DFS channel, and thus dynamically enable or disable the DFS scanning procedures on the unlicensed or shared spectrum.

Abstract: A method for improving device-to-device (D2D) communication in an LTE-Direct communication system includes exchanging communication information between a first user equipment (UE) and a second UE over an LTE-Direct connection with a first network resource of a first set of network resources allocated to the first and second UEs by a base station for the LTE-Direct connection. The method also includes determining, by the first UE, whether a first link quality of the LTE-Direct connection with the first network resource is below a link quality threshold. If so, the LTE-Direct connection is shifted to another network resource of the first set of network resources until an LTE-Direct connection is established that has a link quality that is equal to or greater than the link quality threshold.
