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.
