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: A transceiver compatible with both wide channel constant envelope 4 level FSK FM modulation and narrow channel pi /4 differential QPSK linear modulation allows compatible interaction between modified constant envelope and non-constant envelope transmitters. All Nyquist filtering occurs in the transmitters, and none in the receiver.

Abstract: A base station (101) will request the transmission of quality information from a particular remote stations (102, 103) only when data is queued to be transmitted to the remote stations. Once a remote station begins the transmission of channel quality information, the transmission of such information continues until the data transmission is successfully delivered to the remote station. The base station receives the channel quality information and adjusts the modulation and coding of the remote stations accordingly. Where data is transmitted simultaneously to a plurality of remote stations, a set of queues (303) for the multiple remote stations is maintained, and based on queue status, a channel quality request messages is sent to a sub-set of remote stations with data queued.

Abstract: Remote units (113) having large amounts of data to transmit will be dynamically assigned Orthogonal Variable Spreading Factor (OVSF) codes corresponding to higher data rates and remote units (113) with lower amounts of data to be transmitted will be assigned OVSF codes corresponding to lower data rates. The reduction of the data rate between the base station (100) and remote units (113) occurs by changing the current OVSF codes utilized by both the remote units (113) and the base station (100). In order to eliminate collisions among remote units transmitting data, a remote units transmission is advanced and retarded in time based on an amount of offset from a frame boundary.

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 acknowledgement 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.

Abstract: A generic structure of Hybrid ARQ using Turbo Codes is provided which requires the function of channel coding, redundancy selection, buffering and maximum-ratio diversity combining, channel decoding, error detection, and sending back an acknowledgement to the transmitter (Fig.3). The functions of channel coding and redundancy selection (Fig.1) are performed at the transmitter while the remaining functions are performed at the receiver. The initial code rate can be explicitly communicated to the receiver or blindly detected.

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.
