Abstract: A method an apparatus is described for providing feedback for closed-loop transmitting with multiple transmit and receive antennas. The method includes a first step 900 of providing a codebook containing sets of weightings for each data stream of the multiple transmit antennas with each set identified by an index known to a transmitter and a receiver. The same codebook is utilized for any number of data streams up to the number of transmit antennas. A next step 902 includes measuring a composite channel between the transmitter and receiver. A next step 904 includes determining at least one performance metric for each set of weightings in the codebook. A next step 906 includes selecting preferred weightings for each data stream in response to the performance metrics. A next step 908 includes feeding back an index of the preferred weightings to the transmitter for use in subsequent transmissions.

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: In a telecommunication system (10) for providing multimedia broadcast services to many user equipments (40–45), a physical random access channel (39) is provided for uplink transmission of power control information from the user equipments to a radio site (30, 35). Based upon a comparison of signal-to-noise ratios (53) each particular user equipment sends (55) or inhibits from sending a power control signal to the radio site to which it is coupled. When the radio site of the telecommunication system detects a power control signal (73), the radio site adjusts the transmission power of a broadcast channel intended for reception by multiple user equipments (75) to be incrementally greater than the previous power (81). For lack of detection of a power control signal, adjusts the transmission power of a broadcast channel to be incrementally lower than the previous power.

Abstract: A transmitter uses adaptive array weights to modify a gain and a phase of a communication signal to produce a plurality of element communication signals coupled to antenna elements in an adaptive array antenna. The communication signal is transmitted along with an element pilot signal that is coupled to one of the elements in the adaptive array antenna. In a receiver, the communication signal is received, and the element pilot signal is received. Thereafter, the adaptive array weights used at the transmitter are estimated in response to comparing characteristics of the received element pilot signal to characteristics of the received communication signal.

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 plurality of common radio resources (303) are allocated for receiving combined responses from a plurality of mobile stations (109). A request message, similar to a request for counting, is broadcast to all mobile stations (109) within a coverage area (105) and may indicate a range, for example a signal-to-noise-and-interference ratio range. Mobile stations (109) responding to the request, use specific resources (303) corresponding to respective range values. The infrastructure (103) may use the received information to determine a modulation and coding scheme for PTM broadcast. The total number of responses to the request message may be limited by providing a probability factor within the request message.
