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.

Abstract: Separate forward dedicated and shared control channels (17, 18) are provided in a spread-spectrum communication. The forward dedicated control channel (1 8) is used to communicate persistent control information and point to the share d control channel (17) when further intermittent control information concernin g transmission of data to a mobile station (14) needs to be communicated. The use of a dedicated control channel for only necessary persistent control information, while only pointing to a shared control channel when it is needed, affords more efficient utilization of system resources.

Abstract: Separate forward dedicated and shared control channels (17, 18) are provided in a spread-spectrum communication. The forward dedicated control channel (18) is used to communicate persistent control information and point to the shared control channel (17) when further intermittent control information concerning transmission of data to a mobile station (14) needs to be communicated. The use of a dedicated control channel for only necessary persistent control information, while only pointing to a shared control channel when it is needed, affords more efficient utilization of system resources.

Abstract: A mobile station (110) selects an initial data rate for communication between base station (107) and mobile station (110). Mobile station (110) communicates the selected initial data rate to base station (107) through uplink (112). Base station (107) determines a difference level of interference condition experienced by mobile station (107) between a time when the initial data rate was selected by mobile station (110) and a time when base station (107) prepares to communicate to mobile station (110). Base station (107) selects a final data rate for transmission from base station (107) to mobile station (110) based on the determined difference level of interference condition. As such, the initial data rate may be modified to the final data rate while maximizing the down link capacity.

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.
