Abstract: Apparatus and methods are described for selecting or identifying a first band number from one or more additional band numbers mapped to a frequency division duplexing (FDD) band used in universal mobile telecommunications (UMTS). The one or more additional band numbers may be different from a second band number assigned to the FDD band. Each of the one or more additional band numbers may correspond to a different factor N (e.g., N = 2, N = 4) for use in UMTS scaling. A signal indicative of the first band number may be transmitted to, for example, a network entity, where the signal indicates support of UMTS scaling operations in the FDD band using the factor N corresponding to the first band number.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with improving antenna selection for a UE as part of an access procedure. In an example, a UE with two or more antennas is equipped to obtain receive chain measurements for the two or more antennas associated with the UE when an access procedure is initiated, select an antenna, of the two or more antennas, for transmission based on receive chain measurements for use during at least a portion of the access procedure, and perform the access procedure using the selected antenna. In another example, the UE is equipped to determine that an Access procedure is to be initiated, select an antenna from the two or more antennas based on a selection algorithm, and perform the Access procedure based using the selected antenna. Other aspects, embodiments, and features are also claimed and described.

Abstract: 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.

Abstract: 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.
