摘要： 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.

摘要： A method and apparatus for performing partially coherent Multiple Input Multiple Output (MIMO) transmissions within a multi-carrier communication system is provided herein. During operation similar information bits enter each base station (401, 402). The information bits are encoded by each base station to produce a plurality of systematic bits and parity check bits. Each base station produces a set of similar systematic/parity bits and dissimilar systematic/parity bits. The similar bits are modulated and transmitted using the same resource elements. The remaining symbols are transmitted on any resource elements. Thus the transmissions from multiple base stations are received by the UE partially coherently. Since the same fraction of systematic bits are transmitted from each base station, the transmissions are homogeneous and hence can be received and decoded equally well in any cell are outside the handover region (i.e. closer to base station).

摘要： Separate Radio Network Controllers (11 and 13) exchange (31) neighboring cell information between one another. This information is used (32), 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 uses differing synchronization techniques (43 and 44) depending upon whether or not the multicast content is sourced by base stations that share a common Radio Network Controller. Pursuant to one technique having particular use when the base stations do not share a common Radio Network Controller, the receiver node compares the bearer content of at least one selected data block from one received multicast stream with the bearer content of a selected data block from another multicast stream.
