    摘要: A wireless communication method and system for optimizing channel selection for an AP. The channel selection optimization process includes four sub-processes: 1) a measurement process; 2) a candidate channel determining process; 3) a channel selection process; and 4) a channel update process. Candidate channels used for supporting communication performed by the AP are determined. The candidate channels are chosen from an allowable channel set (ACS) if a detected interference of each candidate channel is less than an established maximum allowed interference.

    摘要: A method and system is disclosed wherein timeslots designated in a wireless communication system as Common Physical Channel (CPCH) timeslots may be reused for user traffic. A CPCH timeslot used in a first cell may be reused by a second cell, assuming the first and second cells transmit control information in different CPCH timeslots, for user traffic. The second cell is permitted to reuse the timeslot in which the first cell is transmitting control information so long as the second cell's reuse of that timeslot does not degrade reception of control information in the first cell.

    摘要: A method for accelerating discovery of access points (APs) in a wireless local area network begins by transmitting an advertisement packet by an AP via at least one channel other than a channel on which the AP transmits beacon signals. The advertisement packet is received by a station (STA), which then determines whether to associate to the transmitting AP. The advertisement packet can include reassociation information, such that the STA can associate to the AP based on the information in the advertisement packet, or timing information, such that the STA can tune to the AP and receive the AP's beacon without dwelling on the AP for an extended period of time.

    摘要: Methods and apparatus are disclosed to facilitate wireless communications between a wireless transmit receive unit (WTRU), legacy base stations and base stations using different operating parameters, such as evolved high speed packet access (HSPA) systems Third Generation Partnership Project ((3GPP) Release 7, Release 8 and beyond). Preferred WTRUs are configured with a medium access control (MAC) sub-layer component having a subcomponent with HARQ buffers, such as a subcomponent configured to provide MAC-es and MAC-e functionality and/or MAC-is and MACi functionality that include hybrid automatic repeat request (HARQ) processes, some of which are preferably operable with enhanced dedicated transport channels (E-DCH). The WTRUs are preferably configured such that they reconfigure their MAC subcomponents during soft handover while minimizing induced latency and data losses associated with HARQ processes. In some embodiments, the WTRUs are configured to prevent flushing of HARQ process buffers in soft handover scenarios with a Node B that does not support UL enhancements, e.g. higher order modulation (HOM). In other embodiments, flushing of HARQ processes is used but amelioration of adverse effects is addressed.

    摘要: A method and apparatus which determine the minimum transmission power level of an access point (AP) for reliably communicating with at least one wireless transmit/receive unit (WTRU) in a wireless communication system. The apparatus obtains the range of the AP and estimates the interference to the AP by executing a slow interference estimation process and a fast interference estimation process. A required received power (RRP) of the WTRU is obtained from the interference estimate. The minimum transmission power level of the AP is determined by summing the range of the AP and the RRP.

    摘要: A method for seamless channel change in a wireless local area network having a station (STA) and an access point (AP) begins by sending a channel change intention message from the AP to the STA. A channel change response message is sent from the STA to the AP, informing the AP whether the STA will follow the channel change. The AP determines whether to proceed with the channel change, and performs the channel change if the determination is positive.
