摘要： A method and apparatus for uplink transmission over a non-contentious shared feedback channel are disclosed, wherein the parameters of the uplink transmission are determined by the parameters of a downlink transmission. A new uplink channel, called a physical shared uplink feedback channel (PSUFCH) is used for uplink transmission such as feedback information in response to a downlink transmission on a fast shared data channel. The content of the feedback information may be general, e.g. an ACK/NACK or a channel quality indicator (CQI). The PSUFCH is transmitted using power ramping that terminates upon reception of a downlink ACK (DLACK) from a Node-B. No ambiguity resolution is required due to the non-contentious and deterministic mapping of the uplink channel resources.

摘要： When a wireless transmit receive unit (WTRU) is using a reduced dedicated physical control channel (DPCCH) frame, the WTRU may periodically send a normal DPCCH frame. The WTRU may periodically increase the transmit power or send a normal DPCCH frame if there is a transmit power control (TPC) error or a downlink quality is below a threshold. When the WTRU implements DPCCH transmission gating, the WTRU may set a gating period based on the number of received TPC commands. The WTRU or Node-B may restore to a normal mode, if the link quality is below a threshold. The WTRU may periodically increase a transmit power. When a reduced signal-to-interference ratio (SIR) target is used for TPC, the WTRU may increase a transmit power, if the downlink power is not responsive. The WTRU or the Node-B may restore a normal SIR target if the link quality is below a threshold.
摘要翻译：当无线发射接收单元（WTRU）正在使用精简专用物理控制信道（DPCCH）帧时，WTRU可以周期性地发送正常的DPCCH帧。如果存在发射功率控制（TPC）错误或下行链路质量低于阈值，则WTRU可以周期性地增加发射功率或发送正常DPCCH帧。当WTRU实现DPCCH传输门控时，WTRU可以基于接收的TPC命令的数量来设置门控周期。如果链路质量低于阈值，则WTRU或节点B可以恢复到正常模式。 WTRU可以周期性地增加发射功率。当降低的信号干扰比（SIR）目标用于TPC时，如果下行链路功率不响应，则WTRU可以增加发射功率。如果链路质量低于阈值，则WTRU或节点B可恢复正常的SIR目标。

摘要： Received signal characteristics of multiple concurrently received channels are determined using an analytical approach for computation. A receiving wireless transmit receive unit and method are provided for processing concurrent communication signals from a plurality of transmitting WTRUs (50k) that concurrently transmit successive data blocks in a plurality of K forward channels. The receiving WTRU (70') preferably has a receiver (86) configured to receive successive data blocks of K concurrent transmissions transmitted from the transmitting WTRUs (50k) on the respective K forward channels. The processor (55k) is configured to successively compute instantaneous signal to interference ratio values for each forward channel j, for integers j=1 to K, based on a cross correlation matrix of channel response characteristics of K concurrently received data blocks and to selectively compute an average value that is used for the computing the individual channel characteristics for the forward channel K. The individual channel characteristics are advantageously used for power control or for the processing of the data blocks received on the respective forward channels.

摘要： 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.

摘要： A system and method for providing variable security levels in a wireless communication network. The present invention optimizes the often conflicting demands of highly secure wireless communications and high speed wireless communications. According to a preferred embodiment of the present invention, various security sensors are scanned to determine the likely presence of an intruder within a predetermined trust zone. If an intruder is likely present, the security level is changed to the highest setting, and consequently a lower data rate, while the intruder is identified. If the identified intruder is in fact a trusted node, the security level is returned to a lower setting. If the identified intruder is not a trusted node, the security level is maintained at an elevated state while the intruder is within the trust zone.
