12/253184

Inventors:

Jerry CHOW - San Diego CA, US
Tricci SO - San Diego CA, US

International Classification:

H04H 20/71

US Classification:

370312

Abstract:

A method for providing a multicast and broadcast service (MBS) in a wireless network, the method comprising: establishing an MBS MAC connection between a mobile station (MS) and a first base station (BS) in an MBS zone; sending a first MBS_MAP message in a first frame, wherein the first MBS_MAP message includes information for locating a second MBS_MAP message in a second frame, but does not specify the location of the second MBS MAP message within the second frame; and sending the second MBS_MAP message in the second frame.

Inventors:

Jerry Chow - San Diego CA, US
Tricci So - San Diego CA, US

International Classification:

H04H 20/71

US Classification:

370312

Abstract:

A system and method for supporting multicast and broadcast service (MBS) on one or more separate carrier frequencies are provided. The system includes carrier frequency information to indicate that data in an MBS zone resides on a separate carrier, and to direct the subscriber stations to receive MBS data on the separate carrier. The method comprises establishing an MBS MAC connection between a subscriber station and a base station in a MBS zone, processing carrier frequency information to determine whether data associated with the MBS zone resides on a separate carrier, and if so, transmitting the MBS data on the separate carrier.

International Classification:

H04H 20/71
H04W 36/00
G08C 17/00

US Classification:

370311, 370312, 370331

Abstract:

A broadcast management message includes MBS Zone Neighbor information to associate different MBS Zones which transmit the same MBS contents over a single frequency or a different frequency. An MBS Zone Service Group contains a group of MBS Zones that transmit the same MBS content over the same frequency or at different frequencies. All the MBS Zones that belong to the same MBS Zone Service Group may have the same MBS Zone Service Group Identifier (ID).

Assignee:

ZTE (USA) Inc. - Iselin NJ

International Classification:

H04W 4/06

US Classification:

370312

Abstract:

A system is disclosed for performing a mobile station handover while continuing a multicast and broadcast service (MCBCS). The system includes a transceiver module transmitting from the mobile station multicast and broadcast service (MBS) zone criteria, including a list of one or more potential target base stations, to a serving base station, if a target base station is not in the same MBS zone as the serving base station. A handover request is made to one or more of the potential target base stations from the serving base station, determined based on the MBS zone criteria, where the MBS zone criteria includes an MCBCS continuity policy of the mobile station. A target base station is then selected, from the list of one or more potential target base stations, that satisfies the MBS zone criteria, and a handover process is performed to the target base station.

US Classification:

Abstract:

Methods and apparatus are provided for managing interference in a wireless backhaul network comprising a plurality of hubs, each hub serving a plurality of remote backhaul modules (RBM), using power control with a one-power-zone (OPZ) constraint. Each hub uses a transmit frame structure comprising a plurality of zones, each RBM is scheduled on a different zone, and the same power level is maintained across all zones within a transmit frame. Under the OPZ constraint, and for scheduling policies under which the number of zones assigned to each RBM is fixed, the power and scheduling sub-problems are decoupled. This enables power control independent of scheduling, using methods having lower computational complexity. Methods are disclosed comprising iterative function evaluation or Newton's method approaches based on a weighted sum-rate maximization across the network, which can be implemented in a distributed fashion. Some of the methods can be implemented asynchronously at each hub.
