Abstract: Techniques, systems and apparatus are described for reducing battery power consumption during a discontinuous reception and transmission mode of operation of a communication device. When operating in the discontinuous reception and transmission mode, a communication device can process radio frequency signals received from base stations to identify a set of active base stations based on a quality of the received radio frequency signals. This can reduce the total number of base stations to decode the corresponding system frame number (SFN). Based on the decoded SFN, the communication device can select a base station to perform hand-off.

Abstract: A scheduling technique is described for discontinuous transmission and reception. The scheduling technique may be implemented in a mobile communication device with multiple SIMs. The scheduling technique facilitates enhanced communication capability for the mobile communication device. In one implementation, the scheduling technique helps avoid substantial overlap between discontinuous receive cycles of the SIMs, for example by renegotiating a discontinuous transmit/receive offset if too much overlap exists. The renegotiation process may be incorporated into a future industry standard communication protocol (e.g., 3GPP release 11 or later), or may be implemented as an extension to an existing communication protocol.

Abstract: A communication controller and a method is provided for synchronizing a wireless communication device and a wireless communication network having two or more transmit antennas, which support transmit diversity. A reference signal is received from the wireless communication network via each one of a pair of the two or more transmit antennas. A preferred phase offset is then determined for the pair of transmit antennas, and then transmitted to the wireless communication network. Further adjustments of the requested phase and amplitude of the communications transmitted using the pair of transmit antennas are suspended, until further transmissions are received from the wireless communication network via the corresponding transmit antennas, which can be decoded in accordance with the preferred phase offset or a timer has elapsed corresponding to the maximum time needed for the wireless communication network to receive the preferred phase offset and synchronize to the same.

Abstract: A communication controller and a method is provided for synchronizing a wireless communication device and a wireless communication network having two or more transmit antennas, which support transmit diversity. The communication controller and method generally provide for receiving a reference signal from the wireless communication network via each one of at least a pair of the two or more transmit antennas. A preferred phase offset is then determined for the at least pair of transmit antennas, and then transmitted to the wireless communication network.
