Abstract:
PROBLEM TO BE SOLVED: To provide methods, apparatuses, and computer program products for facilitating a radio link failure determination.SOLUTION: A wireless terminal is configured to monitor a control channel quality of a control signal over at least one control carrier. A radio link failure determination is then made on the basis of the control channel quality of the at least one control carrier. In other embodiments, rather than basing the radio link failure determination solely on the set of control carriers, the wireless terminal is configured to monitor a control channel quality over at least one additional carrier, not included in the set of control carriers, in response to a link loss detected over each of the set of control carriers. For such embodiments, the radio link failure determination is then made on the basis of the control channel quality of the additional carrier(s).

PROBLEM TO BE SOLVED: To provide a method for facilitating accurate decoding of PDCCH.SOLUTION: Downlink PDCCH is communicated in a manner that mitigates UE from decoding the PDCCH on multiple aggregation levels. Ambiguous payload sizes are identified, and modified through zero padding with one or more bits based on the payload sizes. Aggregation level scrambling sequences can be generated such that the receiving UE can accurately identify the aggregation level on which to decode the PDCCH. Indicator bits that signal the aggregation level to the UE can also be included in the PDCCH.

PROBLEM TO BE SOLVED: To provide a method which makes it possible to communicate retransmission feedback related to multicarrier resource assignments.SOLUTION: The method makes it possible to indicate feedback parameters for a plurality of single carrier assignments, multicarrier assignments and the like according to single carrier-frequency division multiple access (SC-FDMA), relaxed SC-FDMA, etc. Feedback in relaxed SC-FDMA can be bundled by a mobile device to conserve power. In addition, a downlink assignment indicator (DAI) can be utilized to detect and indicate lost grants.
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 techniques to facilitate inter-cell interference cancellation in a wireless network.SOLUTION: An RNTI component manages a set of radio network temporary identifiers (RNTIs) for plural pieces of user equipment (UE). The RNTI component determines whether the UE will likely cause interference with a neighboring cell or experience interference from a neighboring cell, based on each attribute of the UE. The RNTI component includes a space splitting component that allocates a first group of the UE subjected to the determination to a first subset of the divided RNTIs. Based on the determination, the set of RNTIs is divided into at least two subsets. An implicit broadcast component can implicitly broadcast the first subset of the RNTIs to facilitate cancellation of interference possibly caused by the first group of the UE.
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.
