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: A wireless transmit/receive units (WTRUs) receives a downlink transmission from a Node-B and decodes the downlink transmission. If the decoding is not successful, the WTRU sends a pre-defined burst signifying a negative acknowledgement (NACK) to the Node-B via a contention-based shared feedback channel. The pre-defined burst may be sent only once without requiring an acknowledgement. The Node-B calibrates a downlink transmit power so that the downlink transmission is transmitted to the WTRUs with a high likelihood. The Node-B may send a downlink transmission including multiple data streams processed using different modulation and coding schemes so that a WTRU having a high signal quality decodes all data streams while a WTRU having a low signal quality decodes less than all data streams. The Node-B sends a channel quality indicator (CQI) threshold so that each WTRU determines a data stream to report feedback based on the CQI threshold and a measured CQI.

Abstract translation: 无线发射/接收单元（WTRU）从节点B接收下行链路传输并解码下行链路传输。 如果解码不成功，则WTRU经由基于争用的共享反馈信道向节点B发送表示否定确认（NACK）的预定义突发。 预定义的突发可以只发送一次而不需要确认。 节点B校准下行链路发射功率，使得下行链路传输以高可能性被发射到WTRU。 节点B可以发送包括使用不同调制和编码方案处理的多个数据流的下行链路传输，使得具有高信号质量的WTRU解码所有数据流，而具有低信号质量的WTRU解码少于所有数据流。 节点B发送信道质量指示符（CQI）阈值，使得每个WTRU基于CQI阈值和测量的CQI来确定数据流以报告反馈。

Abstract: In a wireless communication system, (e.g., a wireless local area network (WLAN)), including a plurality of wireless transmit/receive units (WTRUs) and a coordinating node, (e.g., an access point (AP)), path loss is estimated by transmitting a loud packet from a first one of the WTRUs to a second one of the WTRUs. The coordinating node transmits a loud packet generation request message. A first one of the WTRUs receives the loud packet generation request message and transmits at least one loud packet at a transmission power specified by the loud packet generation request message. Optionally, the first WTRU transmits a loud packet generation response message. A second one of the WTRUs receives the loud packet and determines a path loss between the first WTRU and the second WTRU by subtracting the signal strength of the loud packet from the determined transmission power of the loud packet.

Abstract: A method for radio resource management (RRM) in a wireless local area network (WLAN) having an access point and a station begins by obtaining a first group of parameters from a current traffic channel. Measurements from all available channels are taken for a second group of parameters. The radio resources of the WLAN are autonomously managed by selectively invoking at least one RRM algorithm that uses at least one parameter. A RRM algorithm may be invoked based upon results produced by a previously executed RRM algorithm, whereby RRM algorithms may be continuously invoked such that the radio resources are autonomously managed.
