Abstract: Aspects of the present disclosure provide techniques for the user equipment (UE) to select a power management mode from a plurality of power management modes supported by the UE based on decoding of a portion of the downlink subframe. For example, when the UE receives a subframe from a base station, the UE may decode a control channel region of the subframe to determine whether the subframe includes a channel grant allocated to the UE. If no channel grant is included in the subframe, the UE may select a power management mode for the UE from the plurality of power management modes supported by the UE that maximizes the UE's sleep opportunities while balancing the deficient performance costs.

Abstract: A process of wireless communication for obtaining channel quality information alignment includes predicting a channel state of a future downlink subframe of a signal. The process also includes providing a base station with a set of parameters based on the predicted channel state. For example, a user equipment (UE) can obtain a recommended transport block size (RTBS) from the predictor process, and return the RTBS to the base station as one of the set of parameters.

Abstract: A method and apparatus for controlling uplink transmit power with optimum delay is described. A transmit power control command may be received. A time slot of the transmit power control command may be determined. Based on the time slot, it may be determined to decode the transmit power control command, with a delay. The transmit power control command may be decoded, after the delay, using a transmit power control command decoding graph by determining a strength of the transmit power control command and plotting the strength on the transmit power control command decoding graph. The transmit power control command decoding graph may include regions. Decoding the transmit power control command, after the delay, may be based on a region associated with plotting the strength of the transmit power control command.

Abstract: Apparatus, methods, and computer program product for data-aided frequency estimation in time division synchronous code division multiple access (TD-SCDMA) include receiving, in a downlink time slot of a TD-SCDMA network, a first data burst before a midamble, the midamble, and a second data burst after the midamble; determining at least one data segment that includes symbols in one or both of the first data burst and the second data burst, where the at least one data segment includes a data segment with fewer symbols than a union of the first data burst and the second data burst; and determining a frequency estimate based on the data segment.

Abstract: When reporting a channel quality metric, such as a channel quality index (CQI) to a base station, a user equipment (UE) may base its report on a calculated spectral efficiency for allocated data channels. The UE may calculate a spectral efficiency metric over a number of subframes to arrive at an average spectral efficiency measurement which may be converted to CQI and reported to a base station.

Abstract: An outer loop for channel quality metric estimation may analyze channel realization and perform adaptive averaging to correct for an inner loop bias. The outer loop may take into account varying channel conditions and may adjust a reported channel quality metric up or down depending on throughput.

Abstract: A user equipment (UE) may employ Timing Advance (TA) reporting to detect possible error conditions during communication between a base station and the UE. In some instances, the UE receives commands to change a timing advance value. The UE declares an error condition when a timing advance value compared with a reference timing advance value changes more than a threshold amount during a specified time period.

Abstract: A user equipment (UE) may improve scheduling of inter radio access technology (IRAT) measurement during continuous data transmission, for example in a High Speed-Physical Downlink Shared Channel (HS-PDSCH). The UE may determine whether an IRAT measurement is desired. The UE may also perform the IRAT measurement during a scheduled downlink data subframe when it is determined the IRAT measurement is desired, without losing the scheduled downlink data.

Abstract: A method and apparatus for controlling transmission power of multiple uplink channels in the same frequency band is described. A first uplink channel may be established with a base station. A second uplink channel may be established with the base station. The first uplink channel and the second uplink channel may be in one timeslot and in the same frequency band. A difference between a transmission power of the first uplink channel and a transmission power of the second uplink channel may be calculated. The transmission power of the first uplink channel and transmission power of the second uplink channel may be individually adjusted based on the calculated difference.

Abstract: Disclosed are apparatus and methods for dynamic data-based scaling of data. The disclosed methods and apparatus involve storing one or more input data samples, which are to be scaled and input to a processing function such as a Fast Fourier Transform. A scaling value operable for scaling the one or more data samples is determined based on the one or more input data samples, and then the stored data samples are scaled based on the computed scaling value when read out of storage prior to the processing function. The scaling of data based on the input data allows the data to be scaled dynamically, not statically, and ensures that the data fits within a desired bit width constraint of the processing function thereby economizing processing resources.

Abstract: Device, system, and method of flicker noise mitigation. For example, an apparatus includes a digital adaptive filter to mitigate flicker noise from a received Orthogonal Frequency-Division Multiplexing (OFDM) signal, wherein the digital adaptive filter includes: a prediction filter to estimate a value of the flicker noise based on linear combination of past low-pass filtered signal samples; a trainer sub-circuit to modify a coefficient of the prediction filter based on a difference between: a known incoming signal filtered by the prediction filter in a training stage, and a locally-generated reference copy of the known signal; a first path including a first pair of analysis-synthesis filters; and a second, parallel, path including a second pair of analysis-synthesis filters and further including the prediction filter.
