Abstract:
PROBLEM TO BE SOLVED: To improve transmission capacity by utilizing multiple carriers.SOLUTION: For multi-carrier operation, a terminal receives an assignment of multiple forward link (FL) carriers and at least one reverse link (RL) carrier. The carriers may be arranged in at least one group, with each group including at least one FL carrier and one RL carrier. The terminal receives packets on the FL carrier(s) in each group and sends acknowledgements for the received packets via the RL carrier in that group. The terminal sends channel quality indication (CQI) reports for the FL carrier(s) in each group via the RL carrier in that group. The terminal also transmits data on the RL carrier(s). The terminal sends designated RL signaling (e.g., to originate a call) on a primary RL carrier and receives designated FL signaling (e.g., for call setup) on a primary FL carrier.

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 controlling power within a wireless communication system.SOLUTION: Downlink power control commands are mapped to resources used for uplink communications within a wireless communication system. An eNode B receives communications from UEs and determines the resources used by the UEs for those transmissions on the uplink which are transmitted at non-optimum power levels. The location of the power control commands is described. (The location of the power control commands is mapped to particular resources used by the UEs for their uplink transmissions.) This facilitates the eNode B to dynamically assign resources for the power control commands while permitting the UEs to decode the power control messages to adjust their power accordingly.
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.
Abstract:
PROBLEM TO BE SOLVED: To reduce power consumption by a communication device in a wireless communication system.SOLUTION: A mobile device utilizes a sleep mode controller that facilitates selecting and/or switching to a desired sleep mode based on predefined sleep mode criteria. The sleep modes include a non-sleep mode, light sleep mode, and/or deep sleep mode. The mobile device employs an analyzer to evaluate information related to explicit signals, implicit signals, and/or the current sleep mode to determine whether a condition is met based on the predefined sleep mode criteria such that a transition to a different sleep mode is to be performed. If such a condition is met, the sleep mode controller urges transitioning from the current sleep mode to a different sleep mode to facilitate reducing power consumption by the mobile device.
Abstract:
PROBLEM TO BE SOLVED: To perform channel estimation for wireless communication.SOLUTION: Techniques for deriving channel estimates with different channel estimation filters are described. In one scheme, a filter selection metric is determined for a signal to be recovered, a channel estimation filter is selected based on the filter selection metric, and a channel estimate is derived with the selected channel estimation filter. In another scheme, a first channel estimate is derived with a first channel estimation filter having a first filter response, a first signal is recovered with the first channel estimate, and interference due to the first signal is estimated and removed. A second channel estimate is derived with a second channel estimation filter having a second filter response that is different from the first filter response.

PROBLEM TO BE SOLVED: To timely provide a response of a (H-ARQ) and link quality feedback for end-to-end VoIP calls traversing GERAN air interfaces. SOLUTION: A control scheme using packet headers, which allows GSM (R) EDGE radio access network (GERAN) systems to increase spectral efficiency, in addition to multiplexing techniques such as superposition encoding, multi-user packet transmission, joint detection, and/or joint decoding fastens feedback to reduce voice over Internet protocol (VoIP) frame transmission latencies, thereby providing the hybrid automatic repeat request (H-ARQ) timely and decreasing incremental redundancy H-ARQ and link quality feedback latencies.
