A rake receiver comprises a plurality of receive antennas and a processing system. Each receive antenna has a plurality of demodulation elements. The processing system is configured to assign a plurality of demodulation elements from a plurality of receive antennas to a multipath group, assign the multipath group to a multipath signal, and independently adjust a time delay value of each demodulation element in the multipath group to correspond to a local time delay of the multipath signal at the corresponding receive antenna.

Time-tracking management of demodulation elements in a receive diversity enabled rake receiver

One aspect of the present invention includes a method of handing off a network session between two different access technologies, in response to a quality of service metric, while maintaining the session. Additional aspects of the present invention are described in the claims, specification and drawings.

Method and apparatus for seamless mobility with layer two assistance

A rate and power control algorithm for a communication system, the algorithm including the steps of: assigning a target channel condition metric to be met at a first terminal for signaling received from each of one or more remote terminals of the system, each terminal supporting a plurality of rates and a plurality of transmit power levels, each target channel condition metric based upon the type of service supported by each remote terminal; receiving a signal at the first terminal from each remote terminal; and adjusting a respective target channel condition metric assigned for a respective remote terminal in response to signal information generated from the received signal. In variations, the algorithm is performed in a distributed manner by different cells of a communication system and at least two of the remote terminals support traffic of different types of service.

Method and apparatus for adaptive QoS-based joint rate and power control algorithm in multi-rate wireless systems

The present invention includes a method and device to support hand off of a session between a mobile terminal and a server, while continuing the session. One aspect of the invention is a method involving a first entity having an IP stack and a second entity having an IP stack. These entities support a hand off from one access technology to another, wherein the different access technologies are differentiated by a characteristic such as their physical layer. Particular aspects of the present invention are described in the claims, specification and drawings.
