Abstract: PROBLEM TO BE SOLVED: To provide methods that facilitate employing flexible signaling of resource block assignments on a control channel.SOLUTION: Resource blocks associated with an uplink or downlink channel can be split into a plurality of groups, and group-specific signaling constraints can be utilized with each of these groups. For example, the group-specific signaling constraints can relate to minimum resource block allocation units and signaling structures utilized for sending assignment indications that allocate resource blocks within the respective groups. Further, an access terminal can have a common understanding of the group-specific signaling constraints; thus, a received assignment indication can be deciphered by the access terminal by utilizing the group-specific signaling constraints.

Abstract: PROBLEM TO BE SOLVED: To provide a system and method for facilitating resource management in OFDM systems.SOLUTION: The system permits different and flexible resource cell metric operations levels (e.g. uplink load management, admission control, congestion control, or signal handoff control) for different sub-bands. For the uplink load management, there are multiple distinct load operation points (e.g. IoT or RoT) per sub-band group instead of the same operation level across the entire available band. The sub-band groups encompass the entire band. The system comprises a variety of transmitting protocols, command increment variable stepsize methods, and robust command response methods. The system thus provides more flexible reverse link resource management and more efficient utilization of the bandwidth.

Abstract: PROBLEM TO BE SOLVED: To provide techniques for efficiently deriving uplink channel estimates without consuming too much special uplink resources.SOLUTION: UE 120 sends a request for uplink resources on a request channel (REQCH) whenever the UE transmits data on the uplink. The UE sends, from multiple antennas, REQCH data on data subcarriers and a pilot on pilot subcarriers. A Node B 110 receives the request, estimates the complex channel gains for the pilot subcarriers on the basis of received pilot symbols, and coherently demodulates received data symbols on the basis of the channel gain estimates. The Node B estimates the complex channel gains for the data subcarriers on the basis of demodulated data symbols, and derives a channel estimate for each antenna on the basis of the channel gain estimates for the pilot and data subcarriers.

Abstract: PROBLEM TO BE SOLVED: To provide a method for supporting cell search in a wireless communication system.SOLUTION: Multiple synchronization transmissions are sent in a frame with non-uniform spacing. Information is conveyed via the non-equal distances between consecutive synchronization transmissions. The multiple synchronization transmissions are sent in different subframes of a frame, and each synchronization transmission is sent in one of multiple symbol periods in a respective subframe. The synchronization transmissions may be sent in non-evenly spaced subframes to convey frame boundary. One synchronization transmission may be sent in one of multiple possible symbol periods depending on the information, e.g., a particular group of cell IDs, being conveyed. The distances between synchronization transmissions may also be used to convey cyclic prefix length. A secondary synchronization transmission carrying a cell ID may be sent at a predetermined offset from one of the multiple synchronization transmissions.

Abstract: PROBLEM TO BE SOLVED: To provide frequency hopping for single-carrier frequency-division multiple access transmission.SOLUTION: User data transmitted within a transmission allocation unit is frequency-shifted with respect to time based slots of the allocation unit. As a result, frequency hopping can be accomplished while preserving single carrier constraints and a low peak to average power ratio (PAPR). Furthermore, various frequency shifted mechanisms are disclosed to accomplish preservation of single carrier restraints. For example, a scheduler selects among cyclic frequency shifting, transposed frequency shifting, and multiplexing of frequency-selectively scheduled and frequency-hopped data based on an audit of scheduled data for the transmission allocation unit. As a result, the reduction in interference achieved through frequency hopping can be combined with the low PAPR for various data allocation configurations.
