    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: 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.

    Abstract: 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.

    Abstract translation: 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。

    Abstract: A method and apparatus for protecting high throughput (HT) stations (STAs) are disclosed. In one embodiment, a physical layer (PHY) legacy preamble transmitted by one STA is decoded by another STA that does not use a legacy preamble. In another embodiment, one STA is identified by another STA by using bits in the preamble of a packet to indicate which PHY type will be used in the remaining portion of the packet. In yet another embodiment, one STA sends ready-to-send (RTS)/clear-to-send (CTS) or CTS-to-self messages for reserving a medium in the presence of another STA of a different type than the one STA. In yet another embodiment, an access point (AP) transmits a beacon or an association message including a capability information element (IE) that indicates operation or support for a legacy preamble, HT STA preambles and a medium access control (MAC) packet transmission with HT protection mechanisms.

    Abstract: A method and an apparatus are provided for efficient transmission of low-data-rate packet services in a multiple-input multiple-output (MIMO) mode of operations in the presence of high-data-rate packet services. Precoding weight information (PWI) is signaled implicitly to a wireless transmit receive unit (WTRU). A precoding weight vector is signaled in a high speed shared control channel less (HS-SCCH-less) transmission using a new HS-SCCH type P. This explicit PWI signaling approach transmits the PWI with minimum power overhead. The data carried in the HS-SCCH type P is encoded to minimize the required transmitted power. A channel type HS-SCCH type 2M is also described.
