    • Determination of transmission power control commands in a UE by combining TPC commands received during DTX/DRX modes. The combining is done on those TPC commands which are received on different radio links after ignoring TPC commands which might be received in a DL slot overlapping with no UL transmission. The UE thus uses the combined TPC commands as derived at the time of entry into DTX for the second UL DPCCH preamble transmission which leads to increase in link reliability and subsequent conservation of power by the UE. The UE uses the same power as derived in the previous slot for resumption of transmission when all the TPC commands, received in the DL slot overlapping with no UL transmission, are UP. TPC commands for the transmission of the 2nd DPCCH preamble at transmission resumption is determined by combining stored TPC commands from each of the radio links that were received by the UE while entering into DTX gap and said TPC commands could not be applied with the newly received TPC commands.
    • 通过组合在DTX / DRX模式期间接收的TPC命令来确定UE中的传输功率控制命令。 在忽略可能在没有UL传输重叠的DL时隙中接收到的TPC命令之后,在不同无线电链路上接收的那些TPC命令上进行组合。 因此,UE使用在进入DTX时用于第二UL DPCCH前导码传输时所导出的组合TPC命令,这导致链路可靠性的增加以及UE的随后的功率节省。 当在没有UL传输重叠的DL时隙中接收的所有TPC命令都为UP时,UE使用与先前时隙中导出的相同的功率来恢复传输。 用于在传输恢复时传输第二DPCCH前导码的TPC命令通过组合来自UE在接收到的DTX间隙期间接收到的每个无线电链路的存储的TPC命令来确定,并且所述TPC命令不能与新接收到的TPC 命令。
