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 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:
A method for operating a device-to-device (D2D) device includes determining, by the D2D device, availability of a D2D buffer status report (BSR) resource. The method also includes in response to determining that the D2D BSR is not available, generating, by the D2D device, a D2D scheduling request (D2D-SR) message in accordance with D2D-SR configuration information and transmitting, by the D2D device, the D2D-SR message in a D2D-SR resource when the D2D-SR resource is available.

Abstract:
A device is configured to perform a method of device-to-device (D2D) communication in a wireless communication network in accordance with a Long Term Evolution (LTE) standard. The method includes entering an RRC-Idle state or an RRC-Connected state. The method also includes transmitting, in the RRC-Idle state or RRC-Connected state, a D2D discovery signal for receipt by at least one second device in the network. The method further includes receiving, in the RRC-Idle state or RRC-Connected state, at least one D2D discovery signal from the at least one second device in the network.
Abstract:
Embodiments are provided for configuring channel measurements and reporting by a user equipment (UE). The embodiments avoid unnecessary cell measurements and resulting reporting transmissions by the UE in network scenarios with restricted downlink transmissions from serving cells. A method by a network component includes sending, to the UE, a data transmission pattern for transmissions on downlinks from multiple cells serving the UE. The data transmission pattern indicates a plurality of subframes including one or more restricted subframes where transmissions from one of the cells are restricted. The method further includes sending, to the UE, a measurement pattern allocating measurements and reports for a cell from the UE to the cells at corresponding designated subframes of the subframes in the data transmission pattern. The UE transmits measurement reports to an assisting serving cell during the one or more restricted subframes.
