摘要： Techniques for selectively combining multiple transmissions to recover a message comprised of multiple frames. Initially, each transmission is separately processed to recover the message. If the message cannot be recovered error-free from any single transmission, then portions of multiple transmissions are selectively combined to recover the message. Erased frames in a message recovered from a primary transmission (e.g., the one with the best pilot Ec/I0) and good frames from other transmissions are determined (e.g., based on the frame-level CRC). One or more combined messages are then formed, each including a different set of good frames substituting for the erased frames. If a good frame cannot be derived from any single transmission for a given erased frame, then symbols from multiple transmissions may be combined to derive the good frame. Each combined message is checked (e.g., based on the message-level CRC) to determine whether it is good or erased.

摘要： 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.

摘要： A method and apparatus for transmitter re-initialization in a wireless communication system (10). When the communication link between a mobile station (38) and a base station (32) is in trouble, the mobile station and the infrastructure prearrange potential rescue base stations (34). The mobile station (38) disables the transmitter during the rescue process. On recovery the transmit power level of the transmitter is incremented for transmission of the pilot strength measurement message until a hand-off direction message is received. The transmit power level is incremented to a maximum value.

摘要： A method for managing a point-to-point call initiated (702) between a wireless mobile station (114, 400) and a remote party while the mobile is receiving broadcast content via one or more multi-user forward-link broadcast channels (508). The mobile station notifies (704) the network (110) of preferences as to prescribed categories of operating conditions, such as whether to continue receiving the broadcast content, and election between the point-to-point call and the broadcast content should network resources be able to conduct the point-to-point call and broadcast content concurrently. In accordance with the preferences, communications are conducted (706) in one of the following operating modes: (1) conducting the point-to-point call and discontinuing reception of the broadcast, (2) conducting the point-to-point call and continuing reception of the broadcast, (3) aborting completion of the point-to-point call and continuing reception of the broadcast.

摘要： Techniques for transmitting and receiving multiple channels with block coding in a communication system are disclosed. In one aspect, a secondary broadcast channel is transmitted concurrently with parity information, encoded from a primary broadcast channel. In another aspect, a mobile station repurposes its receiving circuitry to receive one or more portions of the secondary broadcast channel after a sufficient portion of the primary broadcast channel is received without identified error. In another aspect, secondary broadcast channels associated with a plurality of primary broadcast channels are multiplexed onto a single secondary channel. Various other aspects are also presented. These aspects have the benefit of minimizing mobile station resources required to receive multiple broadcast channels, as well as reducing the complexity and channel resources required to transmit multiple broadcast channels.
