Abstract: A method is provided for operating a multi-bandwidth OFDMA system that can achieve an enhanced bandwidth efficiency due to windowing without significantly impacting the underlying physical design of the receive filters. The method comprises establishing a bandwidth over which the radio resources transmit signals, the bandwidth being comprised of an edge-band and a center-band. Narrow band radio resources are assigned to a portion of the bandwidth that is at least partially within the edge-band.

Abstract: The present invention provides a method of operating an idle mobile unit that is capable of communicating with first and second wireless communication systems. One embodiment of the method includes providing a location update message in response to the idle mobile unit transitioning from a first tracking area associated with the second wireless communication system to a second tracking area associated with the second wireless communication system. The first and second wireless communication systems are capable of paging the idle mobile unit following the location update message.

Abstract: The present invention provides methods involving at least one mobile unit configured to receive wireless connectivity using first and second wireless communication systems that operate according to first and second radio interface technologies, respectively. The first and second radio interface technologies are different. The method may include determining, in response to the mobile unit handing off from the first to the second wireless communication system, session establishment information for the second wireless communication system based on session establishment information associated with the first wireless communication system.

Abstract: In a 3GPP standards Release 6 UMTS system, in order to avoid searching at NodeB for a maximum E-DPCCH-associated metric at discrete possible valid index values, or over disjoint possible valid index regions, at the UE the three different sources of information, the fixed number bits that comprise the RSN, TFI and the H-bit components of the E-DPCCH bit field, are mapped so that the decimal equivalents of the possible E-DPCCH indices lie within a continuous range of values.
