Method and apparatus that provide for broadcast multicast services in an ultra mobile broadband network are disclosed. A broadcast transmission structure provides for efficient indexing of subbands reserved for BCMCS. Transmissions on the logical channels are segmented into error control blocks beginning with zero or one MAC packet received by a MAC layer. A transmitting entity appends parameters relating to content change within a next ultraframe at end of every broadcast packet that is not a stuffing packet. A mapping message of multiple Physical Layer groups addresses a single logical channel when SFN (Single Frequency Network) coverage of an associated subband group is different from SFN coverage of the logical channel.

A method and apparatus configure Femto Devices in an Ultra Mobile Broadband network system. A Femto Device transmits a Femto pilot signal to an Access Terminal, which is served by a plurality of base stations in the Ultra Mobile Broadband network system. The Access Terminal then transmits to the Femto Device an identifier of a base station that controls a macro cell where the Femto Device is located. Next, a Neighbor Discovery Request message is transmitted from the Femto Device to the base station in dependence upon the received identifier of the base station. In response to the Neighbor Discovery Request message received, a Neighbor Discovery Report message is transmitted from the base station to the Femto device. The Neighbor Discovery Report message includes a field indicating network addresses of a Session Reference Network Controller and an Access Gateway that connect to the base station. Finally, the Femto Device connects to the Session Reference Network Controller and the Access Gateway via the Femto device in dependence upon the network addresses of the Session Reference Network Controller and the Access Gateway.
