Abstract:
PROBLEM TO BE SOLVED: To improve transmission capacity by utilizing multiple carriers.SOLUTION: For multi-carrier operation, a terminal receives an assignment of multiple forward link (FL) carriers and at least one reverse link (RL) carrier. The carriers may be arranged in at least one group, with each group including at least one FL carrier and one RL carrier. The terminal receives packets on the FL carrier(s) in each group and sends acknowledgements for the received packets via the RL carrier in that group. The terminal sends channel quality indication (CQI) reports for the FL carrier(s) in each group via the RL carrier in that group. The terminal also transmits data on the RL carrier(s). The terminal sends designated RL signaling (e.g., to originate a call) on a primary RL carrier and receives designated FL signaling (e.g., for call setup) on a primary FL carrier.

Abstract:
Techniques for monitoring grant channels in a wireless communication netw ork are described. In one design, a user equipment (UE) determines whether a monitoring condition is satisfied, monitors at least one grant channel for grants of radio resources if the monitoring condition is satisfied, and stop s monitoring the at least one grant channel if the monitoring condition is n ot satisfied. The UE may determine that the monitoring condition is satisfie d after sending scheduling information indicating that there is data to send , if there is an outstanding grant of radio resources, if a grant of radio r esources is expected, if there is at least one scheduled flow and a data buf fer for the scheduled flow(s) is not empty, if there is an outstanding grant of radio resources and data transmission has been sent using this grant of radio resources, if there is at least one other control channel to monitor, etc.
Abstract:
Un procedimiento para comunicación inalámbrica, que comprende: recibir (912) comandos de control de potencia de transmisión múltiple (TPC) durante una 5 primera ráfaga de transmisión; ajustar (914) la potencia de transmisión de la transmisión enviada durante la primera ráfaga de transmisión basándose en al menos uno de los múltiples comandos de TPC; y ajustar (916) la potencia de transmisión de la transmisión enviada durante una segunda ráfaga de transmisión basándose en al menos dos últimos comandos de TPC entre los múltiples comandos de TPC, separándose la segunda ráfaga de transmisión de la primera ráfaga de transmisión mediante un período de transmisión discontinua (DTX).
Abstract:
Un aparato que comprende: al menos un procesador (1010) para determinar la actividad de datos en un receptor, en base a llegadas esperadas de paquetes o en base a una señal recibida, y para ajustar los informes de indicadores de calidad de canal por parte del receptor, en base a la actividad de datos determinada, en donde dicho al menos un procesador (1010) funciona en una modalidad de conectividad continua de paquetes, que da soporte a la transmisión discontinua, y envía indicadores de calidad de canal con una primera frecuencia solamente durante periodos de transmisión discontinua ACTIVADA, cuando no se detecta actividad de datos, y envía indicadores de calidad de canal con una segunda frecuencia, mayor que la primera frecuencia, durante periodos de transmisión discontinua ACTIVADA y DESACTIVADA, cuando se detecta actividad de datos; y una memoria (1032) acoplada con dicho al menos un procesador (1010).
Abstract:
Techniques for monitoring grant channels in a wireless communication network are described. In one design, a user equipment (UE) determines whether a monitoring condition is satisfied, monitors at least one grant channel for grants of radio resources if the monitoring condition is satisfied, and stops monitoring the at least one grant channel if the monitoring condition is not satisfied. The UE may determine that the monitoring condition is satisfied after sending scheduling information indicating that there is data to send, if there is an outstanding grant of radio resources, if a grant of radio resources is expected, if there is at least one scheduled flow and a data buffer for the scheduled flow(s) is not empty, if there is an outstanding grant of radio resources and data transmission has been sent using this grant of radio resources, if there is at least one other control channel to monitor, etc.
Abstract:
Techniques for reporting channel quality indicators (CQIs) are described. Data activity at a receiver may be determined, and CQI reporting by the receiver may be adjusted based on the determined data activity. In one design, CQI reporting may be enabled for a time window around each expected packet arrival for a periodic or quasi-periodic transmission and may be suspended outside of the time window. In another design, CQI reporting may be varied based on ACK/NACK feedback. In yet another design, CQIs may be sent at a first rate when data activity is not detected and at a second rate faster than the first rate when data activity is detected. In yet another design, CQIs may be sent only during discontinuous transmission (DTX) ON periods when data activity is not detected and may be sent during both DTX ON and OFF periods when data activity is detected.
Abstract:
Methods and apparatus are described for transmitting information units over a plurality of constant bit rate communication channel. The techniques include encoding the information units, thereby creating a plurality of data packets. The encoding is constrained such that the data packet sizes match physical layer packet sizes of the communication channel. The information units may include a variable bit rate data stream, multimedia data, video data, and audio data. The communication channels include CMDA channels, WCDMA, GSM channels, GPRS channels, and EDGE channels.
