    摘要： Network Allocation Vector (NAV) and “beam access control” (BAC) techniques are provided to address data collision problems in WLANs wherein APs provide wireless network access in a service area defined by multiple sectors via use of a switchable antenna system or the like. Preferably, every time the AP visits a sector and before the AP moves on to the next sector, the AP can set the NAV equal to the time it will take until its next visit. Alternatively, or in addition, a BAC bit is transmitted by an AP to control access to the AP by WTRUs disposed in a service sector in which the BAC is transmitted.

    摘要翻译： 提供网络分配向量（NAV）和“波束访问控制”（BAC）技术来解决WLAN中的数据冲突问题，其中AP通过使用可切换天线系统等在由多个扇区定义的服务区域中提供无线网络接入。 优选地，每当AP访问扇区并且在AP移动到下一个扇区之前，AP可以将NAV设置为等于其下一次访问所花费的时间。 或者，或者另外，由AP发送BAC比特，以通过设置在发送BAC的服务扇区中的WTRU来控制对AP的接入。

    摘要： A method and apparatus are described for distributing beacon information. A first WTRU modifies a physical layer protocol data unit (PHY PDU) frame to include beacon information. The first WTRU transmits the modified PHY PDU frame to a second WTRU. The second WTRU receives the modified PHY PDU frame and extracts beacon information from the modified PHY PDU frame. The second WTRU associates with the first WTRU.

    摘要： A method and apparatus for transmitting a packet from a transmitter entity to a receiver entity in a wireless communication system are disclosed. A transmitting entity includes a radio link control (RLC) sublayer and lower layers including a medium access control (MAC) sublayer and a physical layer, where the RLC sublayer provides a protocol data unit (PDU) to the lower layers for transmission. The lower layers using a HARQ entity transmit the PDU to the receiving entity. The RLC sublayer in the transmitting entity, without an indication from an RLC sublayer of the receiving entity, provides the PDU in response to an indication from the lower layers for retransmission.

    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 access point (AP) during wireless communication with at least one wireless transmit/receive unit (WTRU), transmits a beacon signal periodically among a plurality of sectors, each sector having its own sector identity, the beacon signal being periodically received at least once in a beacon period and the beacon period comprising a plurality of beacon service periods for all sectors. The AP determines a scheduling value to indicate a number of inactive beacon periods for a first sector to at least one WTRU located in the first sector. The scheduling value is transmitted with the sector identity for the first sector, such that a variable beacon period is established for the first sector, enabling the at least one WTRU located in the first sector to enter a sleep mode for an adjustable period of time.
