System and method for providing multicast and broadcast services

A communication system for providing a multicast and broadcast service (MBS) by transmitting a plurality of data frames in a wireless network, the system being configured to:

• generate a first MBS data information element (MBS-DATA-IE) in a first one of the data frames, the first MBS-DATA-IE including information relating to a logical channel of the MBS, and indicating a location of an MBS map (MBS-MAP) in a second one of the data frames;
• determine ones of the data frames between the first and second ones of the data frames to add a plurality of extra MBS-DATA-IEs;
• and
• generate the extra MBS-DATA-IEs, each of the extra MBS-DATA-IEs being generated in one of the determined ones of the data frames and including information relating to the logical channel.

A computer-readable storage medium including instructions, executable by a processor in a communication system, for performing a method for providing a multicast and broadcast service (MBS) by transmitting a plurality of data frames in a wireless network, the method comprising:

• generating a first MBS data information element (MBS-DATA-IE) in a first one of the data frames, the first MBS-DATA-IE including information relating to a logical channel of the MBS, and indicating a location of an MBS map (MBS-MAP) in a second one of the data frames;
• determining ones of the data frames between the first and second ones of the data frames in which to add a plurality of extra MBS-DATA-IEs;
• and
• generating the extra MBS-DATA-IEs, the extra MBS-DATA-IEs being generated in the determined ones of the data frames and including information relating to the logical channel.
