Abstract: Embodiments are provided herein for determining a synchronizing master for device-to-device (D2D) communication in a cellular network environment. In an embodiment, a user equipment (UE) receives a discovery signal comprising a timing reference, and determines a transmitter of the discovery signal. In accordance with the determination of the transmitter of the discovery signal, the UE performs one of synchronizing to the timing reference in the discovery signal and transmitting a second discovery signal. The UE performs the synchronizing to the timing reference if the transmitter of the discovery is a cellular network. Alternatively, the UE transmits the second discovery signal upon determining that the transmitter of the discovery signal is a second UE that is out of coverage of a cellular network.

Abstract: A method for device-to-device (D2D) communication includes determining that a first user equipment (UE) is out-of-coverage, the first UE having been previously in-coverage on a first cell. The method also includes starting a timer upon determining that the first UE is out-of-coverage and determining whether the first UE has returned to be in-coverage after starting the timer. Additionally, the method includes determining whether the timer has expired and communicating, by the first UE directly with a second UE, using out-of-coverage resources from the first cell when the timer has not expired and the first UE has not returned to be in-coverage.

Abstract: An embodiment of a system for operating a communications controller for a group of user equipments engaged in a DMC link in a wireless communications system is provided. The communications controller is configured to allocate a set of subframes in one periodic group of subframes to the group of UEs for the DMC link, signal the set of allocated subframes to the group of UEs, and transmit parameters related to a group of HARQ processes of the DMC link. In an embodiment, the communication controller uses HARQ processes for cellular UE transmission that are determined independently from HARQ processes of the group of HARQ processes for the DMC link, and the parameters are configured to enable the group of UEs to manage the group of HARQ processes for the DMC link.

Abstract: A transmit power control rule for device-to-device (D2D) transmissions may not be necessary during periods in which no uplink transmissions are scheduled to be received by an enhanced Node B base station (eNB). When uplink transmissions are not scheduled to be received by the eNB, the eNB may send a transmit power control (TPC) command to a D2D capable user equipment (D2D UE) that instructs the D2D UE to perform a D2D transmission at a pre-defined transmit power level (e.g., maximum transmit power level). When uplink transmissions are scheduled to be received the eNB, the eNB may send a TPC command to the D2D UE that instructs the D2D UE to perform a D2D transmission at a transmit power level defined by a power control rule.

Abstract: 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.

Abstract: A method for operating a communications controller includes defining a positive integer quantity of resource element groups from a resource block with a positive integer number N resource elements in each resource element group, the resource block having a total number of resource elements, the total number of resource elements consisting of available resource elements and reserved resource elements. The method also includes assigning a plurality of available resource elements to fill in each of the positive integer quantity of resource element groups with N available resource elements in each resource element group, and blocking any unassigned available resource elements from being used in a resource element group. The method further includes interleaving a plurality of control messages onto the positive integer quantity of resource element groups, and transmitting the positive integer quantity of resource element groups.
