    Abstract: Un método para detectar y corregir errores de transmisión en un sistema de comunicaciones inalámbricas (600), en que el método comprende: (a) recibir una pluralidad de bloques de datos por medio de una primera transmisión (620), incluyendo cada bloque de datos un único número de secuencia de transmisión (TSN); (b) determinar que un bloque de datos que tenga una TSN esperada no ha sido recibido por medio de una primera transmisión (620); caracterizado por (c) generar un mensaje de informe de estado de TSN (625) que identifica una TSN que falte, correspondiente al bloque de datos que no fue recibido por medio de la primera transmisión (620), incluyendo el mensaje de informe de estado de TSN (625) un primer conjunto de bits usado para identificar la TSN que falta, y un segundo conjunto de bits usado para identificar una cola de reordenación particular (610), ala cual esté destinada la TSN que falta: (d) retransmitir un bloque de datos que incluye la TSN que falta, por medio de una segunda transmisión (630) en respuesta al mensaje de informe de estado de TSN (625); y (e) colocar el bloque de datos retransmitido en un lugar específico en la cola de reordenación particular (610), designado por el segundo conjunto de bits del mensaje de informe de estado de TSN (625),

    Abstract: A wireless hybrid (TDMA/CDMA) user equipment is disclosed. The user equipment receives and recovers signaled information of code and timeslot assignments of the user equipment to support a radio frequency communication. From the signaling information, an identifier of a plurality of assigned timeslots and an indication of a first and last code of a set of consecutive codes are recovered. The last code is identified by an identifier associated with the last code, and the same set of consecutive codes is assigned to each of the plurality of assigned timeslots.

    Abstract: Method of receiving and transmitting downlink data, a user equipment mobile terminal, UE, a base station, BS, and a wireless communication system are disclosed. A base station is configured to transmit a request to provide a channel quality report. A wireless transmit/receive unit, WTRU, configured to provide a channel quality report in response to the request to provide a channel quality report. The base station is further configured to transmit downlink data to the WTRU using an allocation of resources that is based on the channel quality report, and the WTRU is configured to receive the downlink data using the allocated resources.

    Abstract: A wireless digital communication method for communicating between a base station and a plurality of user equipment mobile terminals (UEs) and employs adaptive modulation and coding (AM&C) to achieve improved radio resource utilization and provide optimum data rates for user services. Blocks of downlink (DL) data are received by the base station which requests downlink DL channel quality measurements only from those mobile terminals (UEs) with pending downlink transmissions. The UEs respond to the request by measuring and reporting DL channel quality to the base station, which then allocates resources such that the UEs will make best use of radio resources. The base station notifies the UEs of the physical channel allocation indicating fee modulation/coding rate and allocated slots followed by transmission of blocks of downlink data which are transmitted to the UEs.
