Abstract: A method and apparatus for transmitting and receiving a packet via high speed downlink packet access (HSDPA) are disclosed. At least one HSDPA medium access control (MAC-hs) service data unit (SDU) is segmented into a plurality of segments. MAC-hs protocol data units (PDUs) are generated from the segments wherein each MAC-hs PDU includes at least one segment. Each MAC-hs PDU may include one segment from a single MAC-hs SDU. The size of the segments may match to the size of the MAC-hs PDUs minus the size of the header of the MAC-hs PDU. The sizes of the segments may be determined based on the number of segments to which the MAC-hs SDU is segmented. Alternatively, each MAC-hs PDU may include a combination of segments from a plurality of MAC-hs SDUs or a combination of at least one segment from one MAC-hs SDU and at least one entire MAC-hs SDU.

Abstract: A method and apparatus for sending a channel quality indication (CQI) via a shared channel while a wireless transmit/receive unit (WTRU) is in a Cell_FACH state without having a dedicated channel allocated for the WTRU are disclosed. A WTRU performs a measurement of at least one parameter and generates a CQI based on the measurement. The WTRU then transmits the CQI via a random access channel (RACH). The CQI may be transmitted using an RACH preamble. A plurality of signature sequences may be divided into a plurality of groups. The WTRU may select one group based on the CQI and randomly select a signature sequence among signature sequences in the selected group for transmitting the RACH preamble. The CQI may be appended to the RACH preamble. The CQI may be transmitted via a control part or a data part of the RACH message.

Abstract translation: 公开了一种用于在无线发射/接收单元（WTRU）处于Cell_FACH状态的同时经由共享信道发送信道质量指示（CQI）而不具有为WTRU分配的专用信道的方法和装置。 WTRU执行至少一个参数的测量并基于该测量生成CQI。 WTRU随后经由随机接入信道（RACH）发送CQI。 CQI可以使用RACH前导码来发送。 多个签名序列可以被分成多个组。 WTRU可以基于CQI选择一个组，并且在所选组中的签名序列中随机选择用于发送RACH前导码的签名序列。 CQI可以被附加到RACH前导码。 CQI可以经由RACH消息的控制部分或数据部分来传送。

Abstract: This invention relates to wireless local area networks, and particularly to the IEEE 802.11 family of standards. It consists of a method and apparatus that can be implemented in access points (APs) and subscriber wireless transmit/receive units (WTRUs), in order to allow an AP to initiate re-association of a WTRU to itself or a different AP. The invention improves the robustness of the network by enabling more efficient load balancing, congestion control, and roaming, without compromising the user experience.

Abstract: A method for communicating a list of handover candidates in a wireless local area network from a station to a serving access point (AP) begins by determining a list of handover candidate APs at the station. The candidate list is sorted at the station and is sent to the serving AP. The sending step can include sending the candidate list to the serving AP upon the expiration of a predetermined period of time or upon receipt at the station of an event trigger. The method can also include the step of requesting a candidate list from the station by the serving AP.

Abstract: 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.

Abstract: A method and communication system (e.g., TDD system) that uses adaptive antennas at the base stations to monitor metrics associated with the quality of one or more CPCH timeslots, so as to determine whether to reuse some or all of the CPCH timeslots to transmit the DPCH. If it is determined to reuse some or all of the CPCH timeslots, an additional determination is made as to what limit to apply on the DPCH transmission powers. Adaptive antennas may be used at the base stations to allow the system to reuse some or all of the CPCH timeslots to transmit DPCH, thus improving the overall capacity of the system while maintaining the CPCH coverage and quality at a desired level throughout the system.

Abstract translation: 在基站使用自适应天线的方法和通信系统（例如，TDD系统）来监视与一个或多个CPCH时隙的质量相关联的度量，以便确定是否重新使用一些或全部CPCH时隙来发送 DPCH。 如果确定重新使用部分或全部CPCH时隙，则对DPCH发送功率应用什么限制做出额外的确定。 可以在基站处使用自适应天线来允许系统重新使用部分或全部CPCH时隙来发送DPCH，从而在整个系统中将CPCH覆盖和质量保持在期望的水平的同时提高系统的整体容量。

Abstract: A mesh network includes a plurality of mesh points (MPs), a central database (DB) and a central controller (CC). The MPs are configured to broadcast quality of service (QoS) information over a wireless medium. Each MP may request QoS information directly from at least one other one of the MPs. The MPs store QoS information in the central DB and are configured to query the central DB QoS information associated with any of the MPs. Thus, QoS information is shared throughout the mesh network, and QoS policies are defined and updated where an MP may co-exist with another MP, an MP may co-exist with systems external to the mesh network, and an MP may co-exist with mesh access points (MAPs).

Abstract: A deferral management method is implemented in a wireless local area network (WLAN) including an access point (AP) and a plurality of wireless transmit/receive units (WTRUs). The AP sends a deferral management capabilities request message to the WTRUs to determine the deferral management capabilities of the WTRUs. In response, each of the WTRUs sends a deferral management capabilities indicator message to the AP. The AP may also send a deferral management parameter set message to the WTRUs to indicate values for setting deferral management parameters. In response, each of the WTRUs may optionally send a deferral management parameter set execution confirmation message to the AP. The WTRUs may also set the values of various deferral management parameters in accordance with a certain rule specified in a deferral management rule message sent by the AP. Optionally, the WTRUs may respond to the AP with a deferral management rule execution confirmation message.
