SYSTEM AND METHOD FOR POWER CONTROL COMMAND FOR DEVICE-TO-DEVICE TRANSMISSIONS

摘要

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) (900, 1000). When uplink transmissions are not scheduled to be received by the eNB (900, 1000), the eNB (900, 1000) 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 by the eNB (900, 1000), the eNB (900, 1000) 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.
