Abstract: A wireless terminal and a first node communicate according to a first radio configuration of a first set of radio configurations supported by the first node. A second radio configuration that is available for a second node that supports a second set of radio configurations that is different from the first set of radio configurations is then identified. The wireless terminal and respective ones of the first and second nodes then simultaneously communicate according to the identified second radio configuration. In other embodiments, a wireless terminal is handed off from a first base station to a second base station based on a determination of whether a common radio configuration is available for the first and second base stations. Related wireless communications systems and wireless terminal apparatus are also described.

Abstract: According to some embodiments of the present invention, a reverse link traffic channel code used by a terminal accessing a CDMA wireless communications system is controlled responsive to determining whether the terminal has a duplicate Electronic Serial Number (ESN). In some embodiments, for example, an alternative ESN may be sent to the terminal having the duplicate ESN for use in generating the reverse link traffic channel code. In other embodiments, a time shift may be applied in generating the reverse traffic channel code, such as by time-shifting the reverse link traffic channel code or a long code used to generate the reverse link traffic channel code. In still other embodiments, an alternative long code mask, such as a private long code mask used for a voice privacy feature, may be used responsive to detection of a duplicate ESN.

Abstract: Methods for acquiring service for a wireless terminal can include the steps of camping on a control channel and receiving a request for an operation to be performed by the wireless terminal that is performed by the wireless terminal mutually exclusive of camping on the control channel. Control channel information associated with the control channel on which the wireless terminal was camped is stored and the requested operation is performed. The stored control channel information is used to acquire service for the wireless terminal. Related wireless terminals and systems are disclosed.

Abstract: Methods, receivers, transmitters, and systems are provided for performing a soft hand-over of a mobile terminal between base station transceivers that communicate using different communication channels. A mobile terminal may be configured to receive and demodulate signals on a plurality of different communication channels concurrently and to modulate and transmit signals on a plurality of different communication channels concurrently. This allows, for example, multiple communication connections to be concurrently established between the mobile terminal and a plurality of different base station transceivers that use the different communication channels to communicate.

Abstract: A baseband signal phase-compensation technique offsets undesirable phase shifts, or changes in phase shift, introduced in a transmit signal when changing transmit amplifier operating modes. Such mode changes may, for example, entail switching amplifier stages in and out of an amplification signal path. A phase compensator selectively operates on the baseband signal or signals to subtract out an amount of phase shift equal to the amount of phase shift added by switching one or more additional amplifier stages into the amplification signal path. Compensating baseband signals is this manner may be particularly valuable for the reverse link signal of a mobile terminal operating in a wireless communication environment such as CDMA2000. In such environments, abrupt phase shift changes in the transmit signal associated with transmit signal power control are undesirable.

Abstract: A method for rapidly processing a directed retry (“DR”) message on a mobile station while the mobile station is void of an up-to-date neighbor list or in the process of completing neighbor list measurements. In one aspect of the invention, the method comprises the steps of receiving a directed retry message on a mobile station; setting SCANINTERVAL to zero and HL_FREQ to high if an up-to-date neighbor list does not exist on the mobile station; completing at least one neighbor list measurement within a wait time period; and invoking RTC-4. The step of completing the least one neighbor list measurement is accomplished within a wait time of about four seconds. The step of completing the least one neighbor list measurement preferably comprises completing 2 neighbor list measurements. If the wait time exceeds about four seconds the mobile station reverts to camping or idle condition.
