Abstract: A method and communication system (e.g., a time-division duplex (TDD) system) that uses adaptive antennas at the base stations to monitor metrics associated with the quality of one or more common physical channel (CPCH) timeslots, so as to determine whether to reuse some or all of the CPCH timeslots to transmit a dedicated physical channel (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: 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 di sclosed. A WTRU performs a measurement of at least one parameter and generat es a CQI based on the measurement. The WTRU then transmits the CQI via a ran dom access channel (RACH). The CQI may be transmitted using an RACH preamble . A plurality of signature sequences may be divided into a plurality of grou ps. The WTRU may select one group based on the CQI and randomly select a sig nature sequence among signature sequences in the selected group for transmit ting the RACH preamble. The CQI may be appended to the RACH preamble. The CQ I may be transmitted via a control part or a data part of the RACH message.

Abstract: A method and system for allocating a time slot to each of the base stations for a communication channel to each of a plurality of base stations in a wireless communication system is disclosed. In a wireless communication system, a coverage area of the system is divided into a plurality of cells and each cell is served by a base station. The system receives a list of base stations which need to be configured along with a list of time slots available to transmit the communication channel. A time slot for the communication channel is allocated to each of the base stations in the list based on interference measured at each of the base stations in the list.

Abstract: Un método en un sistema de comunicaciones radioeléctricas de los intervalos de tiempo del reutilización del canal físico común (CPCH), para transmitir señales de canal físico dedicado DPCH a un nivel de potencia que no exceda de un nivel de potencia máxima, incluyendo el sistema (i) una pluralidad de células, en donde cada célula tiene una pluralidad de secciones angulares; (ii) una pluralidad de unidades radioeléctricas de transmisión/recepción (WTRU); (iii) una red de acceso por radio (RAN) para recoger las métricas asociadas con la calidad de los intervalos de tiempo CPCH, y la potencia recibida medida por las mencionadas unidades WTRU; (iv) una pluralidad de estaciones base, las cuales transmiten las señales CPCH a través de una pluralidad de intervalos de tiempo, teniendo las mencionadas estaciones base unas antenas adaptativas operando en las respectivas células mencionadas, en donde cada estación base está en comunicación con las respectivas unidades de la mencionadas WTRU; y (v) unabase de datos que asocie las células con las antenas adaptativas de las estaciones base, caracterizado el método porque: (a) la RAN determina que el sistema de comunicaciones tiene una distribución estable de las métricas CPCH para cada sección angular de cada célula; (b) etiqueta (430, 432) en la base de datos, cada uno de los intervalos de tiempo CPCH como agresivos o no agresivos; (c) incrementa (430) en una magnitud predeterminada la potencia de la señal DPCH transmitida por la estación base en cada intervalo de tiempo CPCH, que esté etiquetada como no agresiva, y en donde la potencia está por debajo de un nivel de potencia máxima predeterminada; (d) se realiza la monitorización (445) de las métricas asociadas con la calidad del intervalo de tiempo CPCH; y (e) cada sección angular de cada célula está asociada con una degradación de la calidad CPCH, determinando las células vecinas respectivas, reduciendo (455) el nivel de potencia máximo para los intervalos de tiempo CPCH en las células vecinas asociadas con la degradación de la calidad CPCH, y etiquetando (460) en la base de datos, las células vecinas como agresivas para los intervalos de tiempo CPCH asociados con la degradación de la calidad CPCH.

Abstract: A method and apparatus for use by a first transceiver, (e.g., wireless transmit/receive unit (WTRU), access point (AP), node) for adjusting the transmission rate of packets transmitted to a second transceiver based on signals the first transceiver receives from the second transceiver. In one embodiment, a transmission packet error rate (Tx PER) process is used to adjust the packet transmission rate. In another embodiment, a relative signal strength indicator (RSSI)-based process is used to determine the RSSI of packets received at the first transceiver from the second transceiver for adjusting the packet transmission rate. In another embodiment, transmission quality indicators are measured at the second transceiver and are sent to the first transceiver, which derives a new packet transmission rate therefrom. The Tx PER and RSSI-based processes may be used individually, in combination, or in conjunction with other processes.
