    Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for implementing confidence metric which is based on a closed loop type transmission diversity. SOLUTION: A method for adapting an antenna array for closed loop type transmission diversity comprises the steps of: receiving an adapting signal, corresponding to an antenna array weighting pattern for a time period; demodulating the adapting signal so as to provide a plurality of codes; determining the confidence metrics for the plurality of codes (S607); forming a set of ordered codes for comparing the plurality of codes, having preferred confidence metric with a code used at the end of the plurality of codes, having non-preferred confidence metric; and selecting an antenna array weighting pattern, corresponding to the set of ordered codes (S627).

    Abstract: In a transceiver in a wireless communications system, data is transmitted fr om the transceiver to subscriber units, wherein each subscriber unit has a requested transmit power and an allocated transmit power, and wherein the allocated transmit power is based upon the requested transmit power. A reque st for an additional power allocation (200) is detected, wherein such additiona l allocation causes a total requested power to exceed a maximum transceiver power (220). In response, allocated transmit power is limited for a minimum number of selected subscriber units (222) needed to reduce a total transceiv er transmit power below the maximum transceiver power (220).

    Abstract: A method and apparatus for providing adaptive bearer configuration for MBMS delivery is disclosed. A first aspect of the present disclosure is a method of operating a wireless infrastructure entity (103) wherein a common radio resource (303) is allocated for receiving a response from at least one mobile station (109). A request message, similar to a request for counting, is broadcast to all mobile stations (109) within a coverage area (105. If at least one mobile station (109) responds to the request, PTM transmission mode will be used for MBMS delivery within the given coverage area (105). If more than one mobile station (109) within the coverage area (105) responds to the request, then all the responses will be over the common radio resource (303). The total number of responses to the request message may be limited by providing a probability factor within the request message.

    Abstract: A method 600 of selecting an ARQ method for retransmitting a data frame based on an accumulated signal to noise ratio (SNR) of systematic bits in the data frame at a receiving unit 508. The sending unit 500 tracks the accumulated SNR of systematic bits by using channel SNR measurement reports sent by the receiving unit 508. The method utilizes Chase combining of re-transmitted systematic bits (via Partial incremental redundancy transmissions) until the accumulated SNR of the systematic bits has reached a suitable value, and then switches to sending only parity bits (via Full incremental redundancy) in retransmissions. In addition, the method alters the allocation of resources, such as code power, to provide only that necessary for successful decoding of the transmitted frame. The sending unit 500 informs the receiving unit 508 of the type of transmission, number of the transmission and/or resource allocation associated with the data frame.

    Abstract: Separate Radio Network Controllers (11 and 13) exchange neighboring cell information between one another. This information is used, in turn, to facilitate macrodiversity reception of multicast content. By one approach, a receiver node (16) receives this neighboring cell information which facilitates compatible reception of corresponding multicast content. The receiver node (16) uses differing synchronization techniques, depending upon whether or not the multicast content is sourced by base stations that share a common Radio Network Controller.

    Abstract: In a wireless communication system using a power control command to control power of a transmitted traffic channel (58), a signal from a transmitter (64) is received (104) via a channel. A channel quality is measured (70, 108) using the signal from the transmitter. In response to the measured channel quality (70) exceeding (80, 110) a channel quality threshold (82), a decrease traffic channel power command is sent (112) to the transmitter, and a channel quality threshold is increased (114). In response to the channel quality threshold (82) exceeding (80, 110) the measured channel quality (70), an increase traffic channel power command is sent (116) to the transmitter, and the channel quality threshold is decreased (118). A traffic signal quality may be measured (72) and compared (88) to a traffic signal quality threshold (86). The result of the comparison (132) may be used to adjust (134) the channel quality threshold (82). The traffic signal quality threshold may be adjusted (90, 126, 128) in response to whether or not a frame error is detected (74, 124).
