  • Methods and systems for downlink transmit power control command transmission
    Patent number: 9918284
    Abstract: Backwards compatibility may be achieved by transmitting an alternating pattern of uplink TPC commands in uplink timeslots. In one example, a served user equipment (UE) receives a downlink TPC command from a serving base station during a downlink timeslot in a sequence of downlink timeslots, and generates an uplink TPC command based on a received power level of the downlink TPC command. The served UE may then transmit the uplink TPC command in an uplink timeslot mapped to the downlink timeslot in which the downlink TPC command was received, as well as transmit an alternating pattern of uplink TPC commands in other uplink timeslots. The alternating pattern of uplink TPC commands may cause a neighboring base station to effectively maintain its transmit power level.
