摘要： Systems and methods are disclosed herein for an enhanced Multimedia Broadcast Multicast Service (MBMS) in a wireless communications network. In one embodiment, a number of base stations in a MBMS zone, or broadcast region, accommodate both Spatial Multiplexing (SM) enabled user elements and 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, 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 to determine when to perform a handoff from one MBMS zone to another.

摘要： A system is provided for optimizing throughput in a communication system. During operation, the system receives, at a first antenna, estimated channel state information (CSI) at least one channel between the first antenna and at least one second antenna. The system obtains antenna correlation information associated with the first antenna and the second antenna, respectively. The system further calculates a set of noise terms associated with random noise for the at least one channel, and optimizes a configuration of beamformers for the first antenna and the at least one second antenna that maximizes a throughput of all antennas, in accordance with the estimated CSI, the obtained antenna correlation information, and the noise terms.
