    • Multiple antenna elements of a WTRU are used to form an adaptive antenna beam pattern for receiving signals in the downlink direction. The WTRU utilizes the formed antenna beam to form a transmission antenna beam for transmitting signals in the uplink direction. In an alternate embodiment, the multiple antenna elements are used to form a plurality of fixed, predetermined antenna beams. The WTRU then selects and switches to the one of the predetermined beams that yields the best downlink reception signals. The WTRU utilizes the selected beam pattern to transmit signals in the uplink direction. In an alternate embodiment, the WTRU receives spectral arrangement information and utilizing this information to avoid transmitting in the direction of spectrally adjacent WTRUs.
    • WTRU的多个天线元件用于形成用于在下行链路方向上接收信号的自适应天线波束模式。 WTRU利用形成的天线波束形成用于在上行链路方向上传输信号的发射天线波束。 在替代实施例中,多个天线元件用于形成多个固定的预定天线波束。 然后,WTRU选择并切换到产生最佳下行链路接收信号的预定波束中的一个。 WTRU利用所选择的波束模式在上行链路方向上发送信号。 在替代实施例中,WTRU接收频谱排列信息并利用该信息来避免沿频谱相邻的WTRU的方向发射。

    • The invention includes several embodiments for slot assignment in code division multiple access communication systems. One embodiment for fixed beams assigns slots by first detecting a beam having the best received quality and selected the best slot from that beam. Another fixed beam embodiment determines the best slot or slots in a number of beams and determines the overall best beam/slot combination. Another fixed beam embodiment uses a modified interference factor. One embodiment for the uplink using adaptive arrays using a spatial analysis stage followed by a transmission power level estimation stage. An overall interference level associated with each slot is determined and a slot having the best overall quality is determined. Another embodiment for the downlink uses the spatial analysis and slot assignment of the uplink for the downlink. Another embodiment for the downlink uses a spatial and transmission power level estimation stages.
    • 本发明包括用于码分多址通信系统中的时隙分配的几个实施例。 固定波束的一个实施例通过首先检测具有最佳接收质量的波束并从该波束中选择最佳时隙来分配时隙。 另一个固定波束实施例确定多个波束中的最佳时隙或时隙,并确定整体最佳波束/时隙组合。 另一固定波束实施例使用修改的干扰因子。 使用自适应阵列的上行链路的一个实施例使用空间分析阶段,接着是传输功率电平估计级。 确定与每个时隙相关联的整体干扰电平,并且确定具有最佳整体质量的时隙。 下行链路的另一实施例使用用于下行链路的上行链路的空间分析和时隙分配。 下行链路的另一实施例使用空间和发射功率电平估计级。

    • 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.

    • A peer-to-peer communication system using a direct link setup (DLS) is disclosed. A mobile station (STA) establishes a direct communication link with another STA by sending a message requesting a DLS to an access point (AP), (i.e., a centralized controller). The AP may accept or reject the DLS request based on channel measurements. If the DLS request is accepted, the DLS is established such that the STAs may directly communicate with each other. An established DLS connection may be torn down by the AP sending a message including a DLS teardown request to one of the STAs, or based on channel measurements. The system may be an Ad hoc network comprising a plurality of STAs without an 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.
