摘要： An access point operates in an 802.11 wireless communication network communicating with a client station, and includes a smart antenna for generating directional antenna beams and an omni-directional antenna beam. An antenna steering algorithm scans the directional antenna beams and the omni-directional antenna beam for receiving signals from the client station. The signals received via each scanned antenna beam are measured, and one of the antenna beams is selected based upon the measuring for communicating with the client station. The selected antenna beam is preferably a directional antenna beam. Once the directional antenna beam has been selected, there are several usage rules for exchanging data with the client station. The usage rules are directed to an active state of the access point, which includes a data transmission mode and a data reception mode.

摘要： A method for taking measurements with a smart antenna in a wireless communication system having a plurality of STAs begins by sending a measurement request from a first STA to a second STA. At least two measurement packets are transmitted from the second STA to the first STA. Each measurement packet is received at the first STA using a different antenna beam. The first STA performs measurements on each measurement packet and selects an antenna beam direction based on the measurement results.

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： A method and apparatus for establishing a set of cells used to support a soft handoff. The apparatus is used in a wireless communication system including a plurality of cells and at least one wireless transmit/receive unit (WTRU) having at least one beam antenna which is configured to transition between a switch beam mode and an omni-directional beam mode. The WTRU communicates with a serving cell while the beam antenna is in the switch beam mode. The WTRU performs measurements on cells neighboring the serving cell to determine measurement results associated with the cells. The WTRU then determines whether each of the measurement results exceeds a predetermined threshold. A set of cells associated with the measurement results that exceed the predetermined threshold is established. If the number of cells in the set reaches a predetermined number, the beam antenna transitions from the switch beam mode to the omni-directional beam mode.

摘要： The present invention is a method for adjusting the uplink transmission power of a WTRU utilizing a switched beam antenna. The method measures the received power of a pilot channel beacon in order to estimate the path loss associated with each directional antenna beam. A beam correction function is calculated based on an estimated gain difference between the beam which is currently used for transmission and the beam to which the WTRU will switch. The transmission power of the WTRU is adjusted according to the beam correction function at the time of beam switching. The beam correction function is equivalent to the response of the WTRU's averaging function to the estimated gain differenceto a step function representing the difference in gain between said first and said second beams, after a beam switch, offset by the same estimated gain difference.the averaged power of a pilot channel beacon received by the WTRU after a beam switch offset by the estimated gain difference between the old beam and the new beam.
摘要翻译：本发明是一种利用切换波束天线调整WTRU的上行传输功率的方法。该方法测量导频信道信标的接收功率，以便估计与每个定向天线波束相关联的路径损耗。基于当前用于传输的波束与WTRU将切换到的波束之间的估计增益差来计算波束校正功能。根据波束切换时的波束校正功能来调整WTRU的发射功率。光束校正功能等效于WTRU的平均功能对估计的增益差的响应，表示在光束切换之后，所述第一和第二光束之间的增益差异的步长函数偏移相同的估计增益差。平均值在波束切换偏移旧光束和新光束之间的估计增益差之后由WTRU接收的导频信道信标的功率。

摘要： Measurements for identifying pre-candidate cells are made by a wireless transmit/receive unit (WTRU) operating with a switched beam antenna in a wireless communication system. The switched beam antenna is a smart antenna generating a plurality of directional beams and an omni-directional beam. The WTRU measures signals from cells not in an active set of cells to define a pre-candidate set of cells. Measured signals from cells in the pre-candidate set of cells are compared to a threshold, and the corresponding cells are moved from the pre-candidate set of cells to a candidate set of cells based upon the comparison to the threshold. A measurement report is then sent to the network.

摘要： Measurement opportunities are provided to a wireless transmit/receive unit (WTRU) operating with a switched beam antenna in a CDMA wireless communication system. The switched beam antenna is a smart antenna generating a plurality of directional beams and an omni-directional beam. The bursty nature of packet data transmission generates periods of inactivity or low traffic during a call. The WTRU switches to antenna beams other than the selected antenna beam for receiving and measuring signals during these periods of inactivity or low traffic. Moreover, if the network has knowledge of the fact the WTRU is operating using a switched beam antenna, the network can use this information when making decisions on channel allocations, thus providing frequent measurement opportunities to the WTRU in order to support the switched beam antenna operation.
