Method and apparatus for service identification in a wireless communication system
First Claim
1. A method of broadcasting content data to a plurality of client stations, the method comprising:
- receiving information regarding a macro-diversity region in which at least one packet comprising content data is allocated;
generating a management message identifying the content data included into the macro-diversity region; and
transmitting a data frame comprising the macro-diversity region and a data region, the data frame being an orthogonal frequency division multiple access (OFDMA) data frame, the management message identifying the content data included into the macro-diversity region being included in the data region of the data frame, the management message including a broadcast channel identifier (CID) that identifies a broadcast service to which the content data belongs.

Abstract
Methods, apparatuses, and systems for announcing services available in a macro-diversity region of a data frame broadcast by a plurality of base stations in a single frequency network to a plurality of subscriber stations, includes a data frame with at least a data region and a macro-diversity region. A media access control (MAC) management message is generated which identifies content and characteristics of the content in the macro-diversity region. Then the MAC management message is transmitted in the data region of the data frame, wherein the MAC management message is decoded by a client station to determine if there is content of interest to the client station in the macro-diversity region of the data frame.

8. A method for identifying content data in a macro-diversity region of data frame, the data frame comprising at least a data region and a macro-diversity region, the method comprising:
-
receiving the data frame, the data frame being an orthogonal frequency division multiple access (OFDMA) data frame; decoding a management message in the data region, the management message including information identifying content data available in the macro-diversity region of the data frame, the management message including a broadcast channel identifier (CID) that identifies a broadcast service to which the content data belongs; determining whether to decode at least a portion of the macro-diversity region of the data frame based on the information identifying the content data in the management message that identifies content data available in the macro-diversity region of the data frame; decoding at least a portion of the macro-diversity region to obtain content data if it is determined to decode the at least a portion of the macro-diversity region; and providing the decoded content data for presentation to a user. - View Dependent Claims (9, 10, 11, 12, 13)

14. A broadcast system for use in broadcasting content data to a plurality of client stations using a data frame, the data frame comprising at least a data region and a macro-diversity region, the system comprising:
-
a first interface configured to receive information regarding a macro-diversity region comprising at least one packet comprising content data; a controller configured to generate a management message that includes information identifying the content data included into the macro-diversity region, the management message for transmission in the data region of the data frame, the management message including a broadcast channel identifier (CID) that identifies a broadcast service to which the content data belongs; and a transmitter configured to transmit the management message and the content data, the management message that includes information identifying the content data included into the macro-diversity region is transmitted in the data region of the data frame and the content data is transmitted in the macro-diversity region of the data frame, the data frame being an orthogonal frequency division multiple access (OFDMA) data frame. - View Dependent Claims (15, 16, 17, 18)

19. A client station that receives services broadcast in a data frame, the data frame comprising at least a data region and a macro-diversity region, the client station comprising:
-
a receiver configured to receive the data frame, the data frame being an orthogonal frequency division multiple access (OFDMA) data frame; a decoder configured to decode a management message in the data region of the data frame, the management message identifying content data included in the macro-diversity region of the data frame, the management message including a broadcast channel identifier (CID) that identifies a broadcast service to which the content data belongs; and a processor configured to determine whether to decode at least a portion of the macro-diversity region based on the information identifying the content data management message that identifies content data included in the macro-diversity region of the data frame and to provide an instruction to the decoder regarding whether to decode the macro-diversity region based on the determination; the decoder being further configured to decode the at least a portion of the macro-diversity region based on receipt of the instruction from the processor. - View Dependent Claims (20, 21, 22)
