PROBLEM TO BE SOLVED: To provide systems and methods for an enhanced Multimedia Broadcast Multicast Service (MBMS) in a wireless communications network.SOLUTION: A number of base stations in an MBMS zone, or broadcast region, accommodate both multiple Spatial Multiplexing (SM) enabled user elements and multiple non-SM enabled user elements. In another embodiment, a number of base stations form a MBMS zone, or broadcast region, where the MBMS zone is sub-divided into an SM zone and a non-SM zone. In another embodiment, the wireless communications network includes multiple MBMS zones. For each MBMS zone, multiple base stations serving the MBMS zone transmit an MBMS zone identifier (ID) for the MBMS zone. The MBMS zone ID may be used by a user element for decoding and/or for determining when to perform a handoff from one MBMS zone to another MBMS zone.SELECTED DRAWING: Figure 1 |
