    Abstract: A method for synchronizing media reproduction across heterogeneous networks is presented. The networks in-clude end-to-end IP broadband and narrowband simulcast networks that contain broadband and narrowband devices associated with a common communications group. A controller in the networks determines delay times for reproduction of a media stream across devices in the networks and establishes the longest delay time. The longest delay time is used to calculate appropriate transmission and reproduction timestamps to permit the devices to reproduce the provided media stream in synchronization. Narrow-band base stations repeat the media stream at the time specified by a transmission timestamp, and broadband end devices repro-duce the media stream at the time specified by a reproduction timestamp. By synchronizing the presentation time, the devices present the media at substantially the same time and are granted fair rights to communicate with one another.

    Abstract: Methods for performing client to client communication in a wireless local area network are disclosed. At an 'n' tier client in the wireless local area network, a signaling message from an 'n-1' tier client is received wherein the signaling message comprises a first period, a second period, and a third period. Communicating with the 'n-1' tier client during the first period and communicating with the 'n+1' tier client during the third period. At an access point in the wireless local area network, an association table identifying clients in the wireless local area network is created and a first period for client to client communication based upon the association table and traffic in the wireless local area network is determined where the access point does not communicate with the clients during the first period.

    Abstract: An outbound message (200) identifies a slot type associated with each timeslot in a scheduling period. In one embodiment, the outbound message further identifies at least an address of a first subscriber group assigned to transmit in a first timeslot (206) if the slot type of the first timeslot is of a first type and an address of a second subscriber group assigned to transmit in a second timeslot (208) if the slot type of the second timeslot is of a second type, wherein the first type and the second type could be the same or different. In a second embodiment, the outbound message further identifies at least a group address associated with a plurality of subscriber units assigned to transmit in a first timeslot if the slot type of the first timeslot is of a first type. In yet a third embodiment, the outbound message further identifies an address of a first subscriber group assigned to transmit in a first timeslot if the slot type of the first timeslot is of the first type, and a second timeslot (210) of a second type.

    Abstract: An inbound message is received over a scalable adaptive modulation ("SAM") interface (104). The inbound message comprises a SAM layer 2 ("L2") header and data in which the SAM L2 header encapsulates. A hardware L2 address is identified for the first device from the encapsulated data and a SAM L2 address is identified for the second device from the SAM L2 header. Once both addresses are identified, an association between the hardware L2 address of the first device and the SAM L2 address of the second device is stored. Similarly, the association may be made between the hardware L2 address of the first device and the SAM L2 address of the first device, or between an Internet protocol ("IP") address of the first device and a SAM L2 address of a second device or the first device.

    Abstract: A slot format and acknowledgment method for use in a communication network that contains one or more wireless links. The slot format provides for the segmenting and reassembly of packets for transport over a wireless link. It also provides support for multiple types of service for the data being carried over the wireless link as well as allocating of access to the wireless link among a plurality of communication units. The acknowledgment method provides for detection of errors over the wireless link, the selective acknowledgment of error-free transmissions and the selective resending of transmissions received in error.
