Abstract: A method and apparatus for handoff to a rescue channel is introduced without the need to send and receive handoff control messages. In the preferred embodiment of the present invention, coordination of the rescue procedure at the infrastructure and mobile station is provided first by disabling the mobile transmitter followed by subsequent detection of signal loss and frame erasures at the serving cells, then by enabling the mobile transmitter followed by subsequent detection of signal by a rescue cell, and finally by enabling the rescue cell channel transmitter followed by subsequent detection and reception of signal and frames by the mobile.

Abstract: Power control in a spread spectrum communication system takes place by determining a speed of a remote unit (405) and assigning as a power-control threshold a target threshold based on the determined speed (410). An instantaneous threshold value is created (415) based on frame-quality information and the target threshold. An energy of a power-control group transmitted (430) from a remote unit is compared to the instantaneous threshold value and a power-adjustment command is determined. The power-adjustment command is transmitted to the remote unit instructing the remote unit to adjust its power accordingly.

Abstract: Forward link communication capacity of a communication system, which is providing from a base station to a number of mobile stations a number of forward communication links corresponding to the plurality of mobile stations, is controlled by receiving gain setting associated with at least one of the forward communication links, comparing the gain setting with a gain threshold, and adjusting a first encoding rate of at least one of the forward communication links to a second encoding rate based on the comparing. A gain offset attunes the gain threshold to update the gain threshold according to a latest condition of the communication system. The gain offset further is used to determine blocking of an incoming call to the communication system.

Abstract: A method of adjusting a power control setpoint threshold (216) in a wireless communication system is provided. The method includes the steps of receiving at a receiver, a communication signal from a mobile communication unit to form a received communication signal, generating a first signal quality indicator (193) based on the received communication signal, generating a second signal quality indicator (194) based on the received communication signal, and generating an estimated signal-to-noise ratio (98). The method further includes setting a predetermined reference region (605) centered around a second signal quality indicator reference (206) where the second signal quality indicator reference (206) is related to the first signal quality indicator (193), and adjusting the power control setpoint threshold (216) based on a comparison between the second quality indicator (194) and the predetermined reference region (605).

Abstract: A communications system provides a method and apparatus for assigning to a mobile station at least a forward communication channel (410) from each sector of a cell in the communication system, assigning orthogonal spreading codes to the least assigned channels, adjusting a transmit gain of at least one of the channels assigned to zero or very low transmit gain, and placing each sector of the cell that has at least one assigned channel in an active channel set at the mobile station.

Abstract: A method and system for retransmitting data packets in a communication system having variable data rates is disclosed. In a preferred embodiment, data packets are packetized to an atomic packet size equal to that of a lowest rate packet. If a data packet requires retransmission at a rate different than that at which the data packet was initially transmitted, the rate is dynamically changed based upon a multiple of the atomic packet size.

Abstract: A code division multiple access (CDMA) communication system (100) has improved control by accurately characterizing coverage and loading parameters related to the CDMA communication system (100). To accurately characterize coverage and loading parameters related to the CDMA communication system, parameter meshes corresponding to parameters of the CDMA communication system are generated. The parameter meshes are evaluated, either individually or in combination, to provide comprehensive information regarding the performance of the CDMA communication system. Based on the results of the evaluation, a controller (113) within the CDMA communication system (100) controls the parameters to improve call quality, loading, etc. of the CDMA communication system (100).
