    Abstract: An evolved Node-B (eNB), user equipment (UE) and method for handling overlapping resource pools for device-to-device (D2D) transmission are generally described. Resources for D2D communication with at least one other UE may be requested by the UE. The allocated pools may overlap. The overlapping pools may comprise pools of the same type or different types. The types of pools may include a discovery pool, a Scheduling Assignment (SA) pool and a Mode-2 data pool. The eNB may resolve conflict among the pools by transmitting an indication of allocation of only one of the pools or may permit the UE to determine which pool to use for transmission. The pool may be selected based on at least one of usage index, configuration identity, and usage priority. The usage index may include traffic types, mode switching, L2 control, UE classification, data rate, real-time/non-real time, latency, and Quality of Service (QoS).

    Abstract: The position of User Equipment (UE) may be determined based on information communicated through direct UE-to-UE communications to obtain additional measurements of position metrics that can be used to determine relative or absolute positions of the UE. In one implementation, a UE may receive, via a direct connection with a second UE, a positioning reference signal from which timing information, relating to distance between the UE and second UE, is derivable; determine, based on the positioning reference signal, a first position metric that relates to a position of the UE with respect to the second UE; and determine, based at least on position metric, a location of the UE.
