Abstract: Embodiments are provided to implement a time/power/frequency hopping scheme for device-to-device (D2D) discovery. The embodiments improve the UE detection of D2D discovery signals from neighboring UEs and account for large number of UEs' discovery signals. This is achieved by having neighboring UEs transmitting at different time instances and at different power levels. Further, neighboring UEs can be configured to transmit on different frequencies. This is achieved by assigning different time/power/frequency sequences to different UEs. An embodiment method includes transmitting, to a UE, parameters a hopping pattern of a first sequence of resources for transmitting a discovery signal by the UE and of a second sequence of resources for receiving a second discovery signal by the UE. The first sequence of resources comprises at least one of a sequence of time instances and a sequence of power levels. The second sequence of resources comprises time instances.

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: An eNB is configured to perform different methods for assigning discovery resources. One method includes receiving a request for discovery resources from an announcing user equipment (UE); allocating a plurality of discovery resources in response to the request; and transmitting a message indicating the plurality of discovery resources, the transmitted message configured to be used by a monitoring UE to determine which discovery resources to monitor. In some embodiments, this may include updating a message to indicate which discovery resources have been allocated, and broadcasting the updated message to a plurality of UEs including the monitoring UE.

Abstract: A device is configured to perform a method of wireless communication in a wireless communication network. The method includes receiving, from a communications controller, a device-to-device (D2D) subframe configuration to communicate with one or more second wireless devices, the subframe configuration indicating one or more subframes in which to transmit a D2D signal or receive one or more D2D signals. The method also includes receiving, from the communications controller, scheduling information to transmit a first signal to the communications controller on a subframe indicated by the D2D subframe configuration. The method further includes prioritizing the transmission of the first signal over a transmission of the D2D signal or a reception of the one or more D2D signals, and transmitting the first signal.

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: A method for cell adaptation includes receiving, by a user equipment (UE), one or more transmission parameters for a transition reference signal (TRS). One or more cells is transitioned between a reduced activity mode and an active transmission and reception mode in accordance with the TRS. The method further includes the UE determining whether or not to transmit the TRS in accordance with one or more TRS transmission criteria, and the UE transmitting the TRS in accordance with the one or more transmission parameters.
