Abstract: A sector switch detection method incorporates two independent, concurrent switch detection processes within a sector switch detection block. A frame-based switch detection process operates over a given single period, while a sliding window-based detection system operates over a selected multiple of periods.

Abstract: A method for transmitting control information from multiple base stations in an active set to a mobile device in a wireless communication system reduces resource consumption by routing information originating from a plurality of active base stations through a single serving base station. The serving base station pools and resolves the information from the active base stations and sends the resolution of the pooled information over a downlink control channel for evaluation and response by the mobile device.

Abstract: A system and method for transmitting and receiving control information over a control channel of a wireless communication system where the conveyed information is coded and then transformed by a set of transform function selected from a plurality of sets of transform functions. The control information is transmitted as replicated sub-frames containing replicated code words and such a string of transformed replicated code words is referred to as a control message. At a receive end inverse transform functions from different sets of functions are applied to a sub-frame of a control message so that if the sub-frame is successfully decoded the inverse transform function applied to such frame allows the timing of the control message to be determined.

Abstract: A method for switching cells by a mobile equipment of a communication system. The mobile transmits a signal coded with a spreading code indicating the mobile's intent to switch cells and the coded information also identifies to which cell the mobile wants to switch. The coded information contains channel measurement adjustment information that is continuously transmitted to the cell which is currently serving the mobile. The flow of channel measurement adjustment information is therefore not disturbed by the application of the method of the present invention. Because the coded information identifies the target cell and indicates the mobile's intent to perform a cell switching procedure, the amount of processing done by the cells is significantly reduced thus increasing the likelihood of a successful switching procedure.

Abstract: A system and method for preventing a call from being dropped changes from a first set of serving base station(s) for the call to a second set of serving base station(s) which can be determined independently by both the wireless unit and the wireless communications system. As such, the wireless unit can attempt to recover the call using the second set of serving base station(s) even without the availability of a communication link between the wireless unit and the current set of serving base station(s). The wireless communications system can independently determine a second set of serving base station(s) for the call using information known at both the wireless communication system and at the wireless unit before the communication link was severed. For example, the wireless unit and the communications system can determine the second set of serving base station(s) using the candidate list identified with a previous pilot strength measurement message (PSMM) known to have been successfully reported to the wireless communications system. After the wireless communications system and the wireless unit determine that a call is in danger of being dropped, the wireless unit and the wireless communications system can automatically add base station(s) in the candidate set to the active set in attempting to recover the call.

Abstract: A method is provided for controlling a traffic-to-pilot ratio (TPR) in a wireless telecommunications channel. The methodology takes advantage of a preexisting feedback process used in hybrid ARQ transmission systems. Generally, information is transmitted over the communications channel, and then the acknowledgement (ACK) signal, or negative acknowledgements (NACK) signal, is used to adjust the TPR. The TPR is adjusted up substantially in response to receiving a NACK signal, and adjusted slightly down in response to receiving an ACK signal. In this manner, the TPR is rapidly adjusted up when a transmission fails, and is allowed to drift slowly down when a transmission succeeds.
