摘要： The system executes a method for transporting a content flow to a wireless access network (104) for broadcast to devices (114,116,112) coupled to the wireless access network (104). The method exists on transmitting a request message to add the content flow to the wireless access network (104), wherein the request message includes a scheduled delivery time, receiving a response message indicating that the content flow will be added to the wireless access network (104), waiting until the scheduled delivery time, and delivering the content flow to the wireless access network (104). The system allows to broadcast multimedia over common networks at higher speeds without entailing costs as known from specialist network.

摘要： Embodiments describe scheduling communication in an ad hoc multihop network. Included is a reservation based Medium Access Control (MAC) protocol that has resources scheduled along the path from source to destination. Admission control is performed on a per-hop basis and a decision is made, in a distributed manner, if enough resources exist along the multihop path to admit a new communication.

摘要： Techniques to more efficiently transmit pilot and signaling on the uplink in an OFDM system. With subband multiplexing, M usable subbands in the system are partitioned into Q disjoint groups of subbands. Each subband group may be assigned to a different terminal for uplink pilot transmission. Multiple terminals may transmit simultaneously on their assigned subbands. The transmit power for the pilot may be scaled higher to attain the same total pilot energy even though S instead of M subbands are used for pilot transmission by each terminal. Pilot transmissions from the terminals are received, and a channel estimate is derived for each terminal based on the pilot received on the assigned subbands. The channel estimate comprises a response for additional subbands not included in the assigned group. Subband multiplexing may also be used for uplink signaling transmission.
