A method and apparatus for spatial Quality of Service (QoS) in a wireless network include determining a relative or absolute location of target devices receiving or requesting a same media stream; determining a group of the target devices within a given proximity of one another utilizing resources from the same wireless access network; for each target device in the group while the resources remain in the wireless network: determining a target device based on relative spatial distance to other target devices in the group with prioritized reception of the media stream; and granting the determined target device prioritized reception of the media stream.

A method and system for direct mode operation (DMO) of a talkgroup enables device to device (D2D) DMO operation leveraged from a Land Mobile Radio (LMR) system. The method includes scanning at a radio receiver a defined radio frequency spectrum; receiving at the radio receiver in the defined radio frequency spectrum a wake-up signal; identifying a talkgroup identifier in the wake-up signal, wherein the talkgroup identifier corresponds to a talkgroup being monitored by the radio receiver; in response to identifying the talkgroup identifier, decoding code sequences included in the wake-up signal; identifying in at least one of the code sequences both a center frequency and a transmission bandwidth of the DMO transmission; and tuning the radio receiver to receive the DMO transmission at the center frequency and transmission bandwidth.

A method and apparatus for multicasting data streams in a wireless radio communication system are provided. A server assigns a plurality of data streams amongst RF resources. One or more points-of-access of the wireless radio communication system are operable to transmit each RF resource to mobile communication devices. Responsive to a request from a mobile communication device for a selected one of the plurality of data streams, the server identifies the points-of-access that have not been assigned, and hence cannot transmit, the RF resource to which the selected data stream is assigned. An access controller instructs those points-of-access to deny association to the mobile communication device. The server then multicasts the selected data stream to the mobile communication device through one of the remaining points-of-access that can transmit the selected RF resource.

Multicast wireless communication system

A method () for supporting telecommunications over a wide area network. The method can include receiving a first message from a first communications site (), the first message communicated through a logical port () at the communications site and maintaining the logical port open for at least a minimum period. A second message can be received from a second communications site (), the second message requesting an identifier associated with the first communications site. Further, a third message can be communicated to the first communications site through the logical port. The third message can identify the second communications site as a candidate for establishing a peer-to-peer communications link over which telecommunications content may be communicated to a first remote unit ().

Peer-to-peer wide area communications system

A method for the selection of forward error correction (FEC)/constellation pairings () for digital transmitted segments based on learning radio link adaptation (RLA) including formatting a packet transmission having a predetermined number of information bits (). The packet is then split into a plurality of segments () where an RLA is used () to determine the optimum format of the packet. The plurality of segments is then sent to a channel encoder for FEC encoding and symbol mapping () at a rate selected by the RLA. The segments are then formatted into packet blocks () and transmitted in blocks that form a time slot at a constant symbol rate.
