Abstract: PROBLEM TO BE SOLVED: To enhance a connection method for mobile unit that efficiently utilizes radio resources. SOLUTION: In the UMTS(Universal Mobile Telephone System), semi-static uplink and downlink connection parameters relating to the frequently-used services of voice, fax, and web browsing are intermittently broadcast to mobile user equipment (20) which stores the parameters. When a mobile station requests (30) one of those services, the relevant dynamic parameters are sent over the radio interface and the mobile station is asked whether it has in its store the relevant parameters for the requested service, if so, the call is set up; if not, the semi-static parameters relevant to the requested service are sent to the user equipment.

Abstract: A method is provided for maintaining synchronization between an AT and a base station during an idle period. During the idle period, a reduced number of uplink reference signals for uplink channel quality estimation are sent to the base station by the AT. The uplink reference signals are sent to assist coherent demodulation and uplink channel quality estimation for scheduling. During the uplink idle period, the numbers of uplink reference signals are designed to be reduced in selective coherent bandwidths. The selection of the coherent bandwidth alternates in time and covers the entire spectrum to allow the channel quality estimation through the entire spectrum.

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: In the method of erasure decoding of acknowledgement (ACK)/negative acknowledgement (NACK) feedback information, a state of received ACK/NACK feedback information for associated sent data is detected based on at least one threshold derived using an objective function. The objective function includes at least a first term representing an affect on data throughput for at least one possible type of error in detecting a state of the received ACK/NACK feedback information.

Abstract: A communication system includes a decentralized, flat architecture where a plurality of base nodes each include controller capabilities so that a centralized base node such as a radio network controller is not required. At least one of the base nodes acts as an anchor node. The anchor node associates a time stamp with at least one packet and provides that to the plurality of base nodes. In one example, a multicast approach is used by a router device for distributing the packet and the associated time stamp to the plurality of base nodes. Each base node controls a timing of a transmission of the at least one packet over a wireless interface responsive to the associated time stamp.
