Aspects of the present disclosure relate to a user equipment (UE) that can maintain active connections on multiple wireless communication networks. The UE shares a transmission resource when transmitting (TX) on a first radio access technology (RAT) and a second RAT in a time-division manual. During TX sharing, the UE provide uplink recovery and protection to one of the RATs.

Disclosed are systems, methods, and computer program products for decoding of transport format combination indicator (TFCI) in a universal mobile telecommunications system (UMTS). In one aspect, a method includes receiving by a UE coded TFCI bit sequence on a physical channel, determining a range of TFCI bits that contain information, performing early decoding of the received TFCI bit sequence; and limiting the search set of decoded TFCI bits to the determined range of TFCI bits. The range of TFCI bits that contain information may be determined from a code book.

The present disclosure presents a method and apparatus for expedited mobile device handover that include performing one or more handover tasks in parallel that have previously been performed exclusively in serial. For example, the disclosure presents a method for wireless device handover, which may include acquiring a target cell, ascertaining a system frame number (SFN) of the target cell, calculating a connection frame number (CFN) for a dedicated channel (DCH) transmission, and reconfiguring a dedicated physical channel (DPCH) based on the calculated CFN. In addition, such an example method may include, while performing at least one of the ascertaining of the SFN, the calculating of the CFN, and the reconfiguring of the DPCH, contemporaneously performing at least one of establishing a downlink dedicated physical channel (DL-DPCH), establishing a synchronization with the target cell, and establishing an uplink dedicated physical channel (UL-DPCH) subsequent to the downlink synchronization.

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.
