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 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 o 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: A method for neighbor scanning in a wireless local area network having a station, a first access point, AP, to which the station is associated, and a second AP, comprising the steps of generating timing information regarding a beacon signal sent by the second AP, reporting the timing information from the first AP to the station and scheduling at the station a time, based on the timing information, to listen for the beacon signal transmitted by the second AP. The timing information includes an indication of a time difference between a second beacon signal sent by the access point and the first beacon signal sent by the second AP and the time difference is an offset in timing units.

Abstract: En un sistema de comunicacion inalambrico que tiene antenas inteligentes y que comprende una pluralidad de unidades transmisoras/receptoras inalambricas (WTRU) se describe un metodo y aparato para transmitir y recibir datos que comprende una primera WTRU que transmite una solicitud para un marco de antena (RFA) a una segunda WTRU. La segunda WTRU recibe el marco RFA y determina una antena preferida para recibir una transmision de marco de datos. La primera WTRU transmite el marco de datos sobre la antena preferida.

Abstract: The method involves sending a deferral management capabilities request message to a wireless transmit/receive unit (WTRU) to report deferral management capabilities of an access point (AP). A deferral management capabilities indicator message is sent to the AP in response to the deferral management capabilities request. A deferral management parameter set message is sent to the WTRU to indicate values for setting deferral management parameters. A deferral management parameter set execution confirmation message is sent to the AP in response to the set message. An independent claim is also included for a wireless local area network (WLAN) comprising an access point (AP).

Abstract: A method and apparatus for routing a packet implemented in a mesh point (MP) of a wireless network are described. According to the method, a plurality of intra-mesh and extra-mesh routes are compared. One of the plurality of intra-mesh and extra-mesh routes is selected for transmission of the packet based on at least one criterion. The packet is transmitted over the selected one of the plurality of intra-mesh and extra-mesh routes.

Abstract: Se divulgan un método y sistema para levar a cabo una comunicacion inalámbrica entre iguales entre estaciones (STAs) dentro de un conjunto de servicios básicos (BSS), conservando al mismo tiempo una conectividad con un punto de acceso (AP) en el BSS. Una STA fuente, un AP y una STA de destino negocian un canal de estructuracion de enlace directo (DLS) para llevar a cabo una comunicacion entre iguales entre la STA fuente y la STA de destino. El canal de DLS puede diferenciarse de un canal de BSS utilizado para una comunicacion entre el AP y cada una de las STAs. La STA fuente y la STA de destino luego llevan a cabo una comunicacion entre iguales sobre el canal de DLS negociado.
