Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a method and an apparatus for an uplink sounding reference signal (SRS) configuration and transmission.

SOLUTION: A method includes the steps of: receiving a configuration of wireless transmit/receive unit (WTRU)-specific SRS subframes for transmitting SRSs and; upon receipt of a trigger, transmitting the SRSs about a plurality of antennas. SRS transmission may be generated in each of duration of WTRU-specific SRS subframes that start by a plurality of WTRU-specific SRS subframes after a triggering subframe. For a plurality of SRS transmission from the plurality of antennas, cyclic shift multiplexing and different transmission combs are used. A cyclic shift for an antenna is determined from a cyclic shift reference value. The WTRU determines the maximum distance between cyclic shifts for the antennas transmitting the SRSs in the same WTRU-specific subframe and allocates a cyclic shift to be determined to each antenna.

【課題】アップリンクサウンディング基準信号(SRS)構成および送信の方法および装置を提供する。
【解決手段】方法は、SRSを送信するために無線送信受信ユニット(WTRU)固有SRSサブフレームの構成を受信するステップと、トリガの受信時に複数のアンテナに関するSRSを送信するステップとを含む。SRS送信は、トリガするサブフレームから複数のWTRU固有SRSサブフレームだけ後に始まるWTRU固有SRSサブフレームの持続時間のそれぞれに発生させることができる。複数のアンテナからの複数のSRS送信について、循環シフト多重化および異なる送信コムを使用する。アンテナの循環シフトを、循環シフト基準値から判定する。同一のWTRU固有サブフレーム内でSRSを送信するアンテナの循環シフトの間の最大距離を判定しアンテナごとに判定される循環シフトを割り当てる。
