Abstract: An outer encoder (612) and an inner encoder (622, 632) encode subsets of information to be transmitted, to improve protection by adding redundancy. The redundancy permits decoding of the information from less than a complete encoded block of information. The use of a combiner 644 at an outer decoder (648) enables better outer decoding of symbols.

Abstract: Techniques for power control of serving and non-serving base stations are disclosed 104. In one aspect, power control commands for a plurality of base stations 104 are combined to form a single command to control the plurality of base stations 740. In another aspect, an "Or-of-up" rule is used to combine the power control commands. In yet another aspect, a channel quality indicator is used to power control a serving base station 730. Various other aspects are also presented. These aspects have the benefit of providing efficient power control between a mobile station and both serving and non-serving base stations, thus avoiding excessive interference and increasing capacity.

Abstract: A method and accompanying apparatus provides for efficient use of communication resources in a CDMA communication system by controlling a transmitting source (300) for transmitting a packet of data over a data frame at a first data rate and at a power level and re-transmitting the packet of data at a second data rate over at least two frames of data at the power level when a receiving destination fails to decode the packet of data. A data rate and power level selector (303) selects the second data rate lower than the first data rate. The data rate and power level selector (303) determines energy per bit of the packet of data at a ratio of the first and second data rates, and selects the second data rate from the ratio such that the determined energy per bit is at a minimum level.

Abstract: A method and apparatus for coordinating the time at which a mobile station (5) performs searches for alternative systems to which a hard handoff will occur. In one system which includes the present invention, the mobile station (5) receives a command which instructs the mobile station (5) as to when to tune to alternative frequencies in order to search for indications of the presence of an alternative system. In another system which includes the present invention, predetermined times are defined with respect to a reference point in time that is common to both an origination base station (10) and a mobile station (5). The mobile station (5) tunes to alternative frequencies to perform searches only during these predetermined times. In addition, the mobile station (5) coordinates the transmission of reports which indicate the results of searches for alternative systems such that these reports are only transmitted from the mobile station (5) when the mobile station (5) is tuned to the origination frequency.

Abstract: The present invention provides a method and apparatus for providing improved quality or power control by recognizing the delays inherent in a closed-loop communication system. The mobile station (12) or receiver properly adjusts its forward link quality or power level thresholds or measurements with which it compares incoming frames or portions thereof to reflect the level it anticipates receiving (after the delay). For example, the mobile station (12) can recognize that at a given measurement time, two outstanding messages have not been executed by the transmitter (where each message indicates a corresponding increase of 1 dB). As a result, the mobile station (12) can adjust its measurement threshold down by 2 dB to more closely correspond to future power adjustments. If the currently received frame or portion thereof is still below the readjusted threshold, then the mobile station (12) sends out a new message to request a further increase in the forward link channel.

Abstract: Techniques for efficient signaling to and from a plurality of mobile stations are disclosed. In one embodiment, a subset of mobile stations may be allocated a portion (350) of the shared resource with one or more individual access grants (370), another subset may be allocated a portion of the shared resource with a single common grant (370), and yet another subset may be allowed to use a portion of the shared resource without any grant. In another embodiment, an acknowledge and continue command is used to extend all or a subset of the previous grants without the need for additional requests and grants, and their associated overhead. In one embodiment, a traffic to pilot ratio (T/P) is used to allocate a portion of the shared resource, allowing a mobile station flexibility in selecting its transmission format based on T/P.

Abstract: A wireless communications network (100) includes roving subscriber-stations (114) and base stations (110) receiving broadcast programs from a content server. A subscriber-station evaluates (618, 620) whether a desired program is available from a subject base station. According to this evaluation, the subscriber-station takes steps to (1) receive the desired program on a shared channel for reception by multiple subscriber-stations (816), or (2) initiate (804, 720) base station delivery (724) of the desired program to the subscriber-station on an individual channel. Responsive to a message from a subject subscriber-station identifying a desired program, a base station either (1) continues (819) transmitting the desired program upon a shared channel, (2) starts (816) transmitting the desired program on a shared channel, or (3) sends the subject subscriber-station a channel assignment message and commences transmission (722) of the desired program on the assigned individual channel.

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.
