    Abstract: PROBLEM TO BE SOLVED: To provide a method for tracking signals in a wireless communication system.SOLUTION: A base station includes a rake antenna having multiple fingers. When any of the fingers goes out of lock, the base station waits for a predetermined time period and then adjusts a lock detect filter. The adjustment is based on comparison of received signal energy with an adjusted energy threshold. The comparison may result in an increased energy level of the filter. In one embodiment, if a mobile station is in soft hand-off, the base station ignores the lock state of the fingers and transmits power control information based on the received signal energy. If the mobile station is not in soft hand-off, a predetermined power control pattern is applied for gradual power adjustment.

    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).

    Abstract: 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.

    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 techniques for sending messages for system access.SOLUTION: User equipment (UE) sends a first message with power headroom and/or buffer size information for system access. A Node B determines at least one parameter (e.g., a resource grant, power control information, etc.) based on the power headroom and/or buffer size information. The Node B sends a second message with the parameter(s). The UE sends a third message based on the parameter(s), e.g., with uplink resources indicated by the resource grant, with transmit power determined based on the power control information, etc. In another aspect, the UE sends a radio environment report in the third message. The report may be used to select a frequency and/or a cell for the UE. In yet another aspect, the second message includes power control information, and the UE sends the third message based on the power control information.
