  • Patent number: 8948094
    Abstract: A method and apparatus for optimizing downlink transmission in a wireless communication network (100) includes determining (502) a distance of each of a plurality of remote devices (102-114) from a network node (120) and allocating (506) downlink symbols of a frame (300) for the downlink transmission based on the determined distance of each of the plurality of remote devices. Earlier downlink symbols of the frame are allocated to at least one remote device of the plurality of remote devices positioned more distant from the network node in comparison to at least other remote device positioned less distant from the network node.

  • Patent number: 7853220
    Abstract: A wireless communication terminal configured to receive broadcast information on a broadcast channel, to start a timer when a reception quality of the received broadcast information degrades below a specified level on the broadcast channel, and to transmit feedback information only after starting the timer.

  • Patent number: 7729696
    Abstract: A communication system is provided that minimizes access message collisions when multiple mobile stations attempt to access a network after updating configuration information and/or access parameters information via a same overhead message by providing for each such mobile station to determine whether, or when, to convey an access message based on a time period corresponding to a wait for the overhead message by the mobile station.

  • Patent number: 7688760
    Abstract: A communication system is provided that allows a Hybrid Access Terminal (HAT) that is monitoring, or is engaged in a circuit voice call in, a circuit switched network and has a dormant packet data session anchored on a packet switched network, to send packet data to, and to receive packet data from, a packet data network connected to the packet switched network without having to switch to the packet switched network and even though a packet data session is not established in the circuit switched network.

  • Patent number: 7673063
    Abstract: In the present technique of streaming a main media stream that has been requested, an anti-shadow stream (36) that represents a backup copy of the main media stream (24) is sent along with an output media stream (34) that represents an output copy of the main media stream. The content of the anti-shadow stream (36) is preferably forward-shifted in time from the output media stream (34) so as to provide replacement of loss data of the output stream. Put differently, sequenced data frames of the output stream (34) are delayed by order compared to that of the anti-shadow stream (36).

  • Publication number: 20090168686
    Abstract: A method in a wireless communication network infrastructure entity including broadcasting information on a broadcast channel for receipt by broadcast wireless communication terminals in the wireless communication network, transmitting (210) a report triggering command to the wireless communication terminals, wherein the report triggering command triggers reporting of feedback information for the channel by the wireless communication terminals upon satisfaction of a condition.

  • Patent number: 7492752
    Abstract: Various embodiments are described to address the need for channel maintenance/channel quality signaling that can better utilize reverse link capacity and conserve battery life. Generally expressed, a remote unit (101) enters (403) a high-rate-channel-maintenance mode in which it transmits channel maintenance signaling. When a low-rate condition is met (405), the remote unit enters (407) a low-rate-channel-maintenance mode in which it transmits channel maintenance signaling at either a lower rate or a lower transmit power than when in the high-rate-channel-maintenance mode. Then when a high-rate condition is met (409), the remote unit reenters the high-rate-channel-maintenance mode.
