Abstract: Various embodiments are provided for determining a set of acceptable transport format combinations for transmission on a current time frame. A set of acceptable modified rate power adjustment values is determined based on a maximum power level, an accumulated power commands and an initial power control command. A set of acceptable channel gain factors is determined based on the set of acceptable modified rate power adjustments values, and the set of acceptable transport format combinations is determined based on the set of acceptable channel gain factors. A possible set of modified rate power adjustment values is associated to a set of channel gain factors for determining the set of accepted channel gain factors based on various design of a transmitter chain used for transmission of data from the mobile station.

Abstract: A method and system that enables multiplexing a plurality of data streams onto one data stream based on data stream priorities and available transport frame combinations (TFCs) is disclosed. A mobile station 12 has applications that produce separate data streams. Example applications include voice 32, signaling 34, E-mail 36 and web applications 38. The data streams are combined by a multiplexer module 48 into one data stream called the transport stream 50. The transport stream 50 is sent over the reverse link to base station transceivers (BTS) 14. The multiplexer module 48 multiplexes the data streams onto the transport stream according to their priorities and the available TFCs.

Abstract: Transmission techniques are provided that improve service continuity and reduce interruptions in delivery of content that can be caused by transitions that occur when the User Equipment (UE) moves from one cell to the other, or when the delivery of content changes from a Point-to-Point (PTP) connection to a Point-to-Multipoint (PTM) connection in the same serving cell, and vice-versa. Such transmission techniques enable seamless delivery of content across cell borders and/or between different transmission schemes such as Point-to-Multipoint (PTM) and Point-to-Point (PTP). Mechanisms for adjusting different streams and for recovering content from each data block during such transitions are also provided so that data is not lost during a transition. In addition, mechanisms for realigning data during decoding at a receiving terminal are also provided.

Abstract: Techniques to implement MBMS services in a wireless communication system. In one aspect, a method is provided for processing data for transmission to a plurality of terminals. Frames of information bits (which may have variable rates) are provided to a buffer implementing a matrix. The matrix is padded with padding bits based on a particular padding scheme to support variable frame rates. The frames are then coded based on a particular block code to provide parity bits. The frame of information bits and the parity bits are then transmitted to the terminals. In another aspect, a method is provided for controlling the transmit power of a data transmission to a plurality of terminals. In accordance with the method, TPC streams are received from the terminals and processed to obtain a stream of joint power control commands used to adjust the transmit power of the data transmission.

Abstract: Se proporcionan tecnicas de transmision que mejoran la continuidad de servicio y reducen interrupciones en la distribucion de contenido que pueden provocarse por transiciones que ocurren cuando el Equipo de Usuario (UE) se mueve de una celda a otra, o cuando la distribucion de contenido cambia de una conexion de Punto a Punto (PTP) a una conexion de Punto a Multipunto (PTM) en la misma celda de servicio, y viceversa. Tales tecnicas de transmision permiten distribucion sin uniones de contenido a traves de bordes de celdas y/o entre diferentes esquemas de transmision tal como Punto a Multipunto (PTM) y Punto a Punto (PTP). Mecanismos para ajustar diferentes corrientes y para recuperar contenido de cada bloque de datos durante tales transiciones tambien se proporcionan de manera que los datos no se pierden durante una transicion. Ademas, tambien se proporcionan mecanismos para realinear datos durante la descodificacion en una terminal de recepcion.

Abstract: To transmit notification indicators for broadcast and multicast services, a base station maps the services to random sequences based on their identifier s. The base station generates the random sequence for each service based on a hash function or a PN generator and the service identifier. Each random sequence is associated with a specific location for sending a notification indicator in each frame. The locations for the notification indicators for each random sequence are randomized with respect to the locations for the notification indicators for each remaining random sequence. This randomness characteristic reduces the likelihood of false alarm. For each service, the base station sets the notification indicators to the same notification value in each modification period. The base station transmits the notification indicators for each service at the random locations determined by the random sequence for the service.

Abstract: Techniques for transmitting signaling information for broadcast and multicas t services are described. A base station transmits signaling information for each service in accordance with a schedule that includes a repetition period and a modification period. The signaling information is sent in each repetition period to allow wireless devices to quickly obtain this information. Changes to the critical signaling information are permitted at the start of each modification period, which is an integer multiple of the repetition period. Whenever the critical signaling information for a given service is changed in a given modification period, a notification indicator for the service is set in an entire preceding modification period to inform the wireless devices of the impending change. The wireless devices can detec t the notification indicator being set in the preceding modification period an d can retrieve the updated critical signaling information in the following modification period.

Abstract: Techniques for determining valid (i.e., supported) TFCs from among all configured TFCs for normal and compressed modes. These techniques maintain sufficient historical information such that 'TFC qualification' may be accurately performed. In a first scheme, Tx_power-requirement states are maintained for different combinations of each TFC. One combination is applicable for each TFC at each TFC interval, and valid TFCs are determined from applicable combinations in the proper state(s). In a second scheme, two Tx_power_requirement states are maintained for each TFC for the normal and compressed modes. In a third scheme, a single Tx_power_requirement state is maintained for each TFC for both modes based on a particular relative power requirement. In a fourth scheme, Tx_power_requirement states are maintained for a set of relative 'bins' that cover the total range of required transmit power for all TFCs. And in a fifth scheme, a set of relative power requirement thresholds are maintained.
