  • Patent number: 6307846
    Abstract: The method operates in a wireless communication system (100) that includes a paging channel (202) and a plurality of quick paging channels (204). A plurality of paging channel time slots (206) are defined within the paging channel, and a plurality of quick paging channel time slots (208) are defined within the quick paging channels. The method includes determining paging indicators (210) in a quick paging channel time slot; determining if there is a time collision (304) between paging indicators that would be set on different quick paging channels; selecting a message associated with one of the paging indicators involved in the time collision; and canceling the selected message, or rescheduling the selected message such that the message is sent in a subsequent paging channel time slot.

  • Patent number: 6275488
    Abstract: A method in a communication system (100) includes transmitting from a source user (101) a first data packet (111) over a first time frame (121) having a finite time period (131), transmitting from source user (101) a second data packet (112) over a second time frame (122) immediately subsequent to first time frame (121), detecting an acknowledgment of acceptable reception of data packet associated with either first or said second data packets (111 and 112), repeating transmission of first and second data packets (111 and 112) in a sequence of first and second time frames (121 and 122) in a time frame sequence (190) until the detection.

  • Patent number: 6192040
    Abstract: A method and apparatus in WCDMA communication system includes extracting pilot symbols (462-5) of (2-M) plurality of communication channels of (1-M) plurality of communication channels based on corresponding 2-M assigned codes (405-436) to produce a plurality (2-M) of extracted pilot symbols (482-96), and combining a first (1) extracted pilot symbol (420) of a first (1) communication channel of (1-M) plurality of communication channels and the plurality (2-M) of extracted pilot symbols (482-96), to produce a combined extracted pilot symbol (498) which is used to produce a combined channel estimate (417) for decoding a first (1) extracted data symbol (414) of first (1) communication channel of (1-M) plurality of communication channels.
