    Abstract: The invention includes various embodiments for use in physical layer processing. One embodiment determines the address mapping of bits in the physical channel buffer from the address of bits in the first interleaver buffer. The physical channel buffer addresses are determined corresponding to addresses of the bits after rate matching, bit scrambling, second interleaving and physical channel mapping. The bits are directly read from the first interleaver buffer and written to the physical channel buffer using the determined physical channel buffer addresses. Another embodiment determines the address mapping of bits in the first interleaver buffer from the address of bits in the physical channel buffer. The first interleaver buffer addresses are determined corresponding to addresses of the bits after reverse rate matching, reverse bit scrambling, reverse second interleaving and reverse physical channel mapping. The bits are directly read from the determined first interleaver buffer addresses and written to the physical channel buffer addresses.

    Abstract: The invention includes various embodiments for use in physical layer processing. One embodiment determines the address mapping of bits in the physical channel buffer from the address of bits in the first interleaver buffer (82). The physical channel buffer addresses (84) are determined corresponding to addresses of the bits after rate matching (88), bit scrambling (90), second interleaving (92) and physical channel mapping (94). The bits are directly read (78) from the first interleaver buffer (82) and written to the physical channel buffer (84) using the determined physical channel buffer addresses. Another embodiment determines the address mapping of bits in the first interleaver buffer (82) from the address of bits in the physical channel buffer (84). The first interleaver buffer addresses are determined corresponding to addresses of the bits after reverse rate matchin g (88), reverse bit scrambling (90), reverse second interleaving (92) and reverse physical channel mapping (94). The bits are directly read from the determined first interleaver buffer addresses (82) and written to the physic al channel buffer addresses (84).

    Abstract: A method and apparatus for adjusting a channel quality indicator (CQI) feedback period to increase uplink capacity in a wireless communication system are disclosed. The uplink capacity is increased by reducing the uplink interference caused by CQI transmissions. A wireless transmit/receive unit (WTRU) monitors a status of downlink transmissions to the WTRU and sets the CQI feedback period based on the status of the downlink transmissions to the WTRU. A base station monitors uplink and downlink transmission needs. The base station determines the CQI feedback period of at least one WTRU based on the uplink and downlink transmission needs and sends a command to the WTRU to change the CQI feedback period of the WTRU.

    Abstract: La presente invencion se refiere a un metodo y aparato para ajustar un periodo de retroalimentacion indicador de calidad de canal (CQI) para incrementar la capacidad de enlace ascendente en un sistema de comunicacion inalambrico. La capacidad de enlace ascendente es incrementada reduciendo la interferencia de enlace causada por las transmisiones del CQI. Una unidad transmisora/receptora inalambrica (WTRU), monitorea un estado de transmisiones de enlace descendente a la WTRU y establece el periodo de retroalimentacion del CQI basado en el estado de transmisiones de enlace descendente a la WTRU. Una estacion base monitorea las transmisiones de el enlace ascendente y enlace descendente necesarias. La estacion base determina el periodo de retroalimentacion del CQI de al menos, una WTRU basado en las transmisiones de enlace ascendente y enlace descendente necesarias y envia una instruccion a la WTRU para cambiar el periodo de retroalimentacion del CQI de la WTRU.
