    Abstract: PROBLEM TO BE SOLVED: To surely converge an initial target SIR of NRT data into a desired target SIR, by utilizing a Temp-DCH allocation duration as an additional parameter for strengthening power control. SOLUTION: A method, system, and components for outer loop power control 500, particularly useful for non-real time data services, uses data transmitted in many short bursts of short duration, called Temp-DCH allocations (509). A target metric, preferably target SIR (502), is adjusted with differing step-up and step-down target metric adjustments. The initial target SIR (502) and the transient step size for target SIR adjustment (505-507) are determined in a dynamical way, in the outer loop power control for each Temp-DCH allocation (509) of non-realtime data.

    Abstract: A method and apparatus are provided for signaling collision avoidance behavior, and in particular deferral and/or backoff behavior, within a communication frame. Preferably, collision avoidance data is explicitly communicated and wireless transmit/receive units (WTRUs) are configured to use such data to generate instructions to control the WTRUs' deferral, backoff and/or other collision avoidance behavior. Instructions generated by the WTRU in this regard may take the form of simply adjusting one or more timing control values used to dictate deferral, backoff and/or other collision avoidance behavior.

    Abstract: A method and apparatus for distributing beacon information includes a first WTRU modifying a physical layer convergence protocol (PLCP) header in a physical protocol data unit (PHY PDU) frame to include beacon information. The first WTRU transmits the modified PLCP header to a second WTRU. The second WTRU receives the modified PLCP header and extracts beacon information from the modified PLCP header. The second WTRU associates with the first WTRU.

    Abstract: The present invention is related to a method and system for sending and reducing uplink feedback signaling by a wireless transmit/receive unit (WTRU) related to transmission of multimedia broadcast multi cast service (MBMS) data over a high speed down link packet access (HSDPA) channel. A Node B may pre-allocate a time frequency region or a common channelization code for the feedback. A triggering criterion for reporting a channel quality indicator (CQI) is set and WTRUs send a CQI to a Node B only if the triggering criterion is satisfied. The triggering criterion may be a current operating CQI value at the Node B, or based on erroneous transport block reception statistics, or a predetermined time period. A feedback reduction method related to ACK/NACK includes the WTRU sending an indication of an average number of transmissions needed to successfully decode the data instead of sending an ACK/NACK for every transmission interval.

    Abstract: 【課題】無線ローカルエリアネットワークにおける管理フレームおよび制御フレーム交換の応答性を改善する方法およびシステムを開示する。【解決手段】イニシエータは、フレーム(アクションフレーム、管理フレーム、制御フレーム、またはデータフレーム)をレスポンダに送信する。フレームが正しく受信されると、レスポンダは、イニシエータに肯定応答(ACK)パケットを直ちに送信する代わりに、応答フレームを送信する。レスポンダは、無線媒体にアクセスしてショートフレーム間隔(SIFS)内に応答フレームを送信することが好ましい。この手法を用いると、応答フレームを送信する上で必要となる無線媒体の競合に関連する長い遅延が回避され、したがってフィードバックメカニズムの応答性および適時性が大幅に改善される。応答フレームは、別のパケットにピギーバックすることも、集約することもできる。【選択図】図2
