    摘要: An apparatus and a method for improving packet transmission and reducing latency in VoIP over WLAN using switched beam antennas having multiple directional antenna beams are disclosed. In an access point having a switched beam antenna, or other smart antenna system, the present invention extends the coverage area of an access point for authentication and association of a new WTRU, extends the access points coverage area during in session transmissions with a WTRU, and adjusts data rates. The method also controls Contention Period (CP)/Contention Free Period (CFP) timing amongst beams emanating from an access point having a switched beam antenna, or other smart antenna system. Fast diversity switching, frame level switching, lowered data rates, and scanning multiple directional antenna beams for the optimum transmission beam are disclosed to improve beam selection and packet transmission.

    摘要: A method and apparatus for selecting a beam combination of beam switched antennas in a multiple-input multiple-output (MIMO) wireless communication system including a first node and a second node. The first node sends a plurality of modulation and coding scheme (MCS) requests to the second node. Each of the plurality of MCS requests is sent using a particular beam combination. The second node receives the MCS requests and generates MCS feedback signals for each of the MCS requests. Each MCS feedback signal includes an MCS recommendation for the particular beam. The first node selects a beam combination for communicating with the second node based on the MCS recommendations.

    摘要: The present invention is a method and apparatus for dynamically adjusting deferred transmission level and a transmission power level in a wireless communication system implementing carrier sense multiple access/collision avoidance (CSMA/CA) mechanism. A plurality of transmission power levels and associated metrics are defined for an access point (AP) and a wireless transmit/receive unit (WTRU). If a packet originated from a neighboring basic service set (BSS) is received, the metric is updated for each of the transmission power levels. The metric is increased if it is determined that transmission at a particular transmission power level associated to the metric would cause a partial defer to a sender and a receiver of the packet. The AP and the WTRU selects a transmission power level having a smallest metric. The AP and WTRU may also adjust the deferred transmission level in accordance with measurement results.

    摘要: 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 multicast service (MBMS) data over a high speed downlink 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.

    摘要: A method and apparatus may be used for peer-to-peer communications. A first non-access point (non-AP) station (STA) may receive a message for establishing a direct communication link from a second non-AP STA. The message may include a service priority. The first non-AP STA may transmit another message in response to receiving the message from the second non-AP STA, and communicate directly with the second non-AP STA. The system may be an Ad hoc network comprising a plurality of STAs without an access point (AP) where each STA maintains a database of one-hop and two-hop STAs, and establishes a direct link to other STAs after informing neighboring STAs of an intention to establish a direct communication link.
