摘要： A device and method for power saving between a scheduling request and a grant. A user equipment (UE) establishes a connection to a network, the UE and the network may be configured with a Connected Discontinuous Reception (C-DRX) functionality, the C-DRX functionality including a cycle with at least one onDuration. The UE transmits, during a first subframe a scheduling request (SR) to the network, the SR corresponds to data that is to be transmitted by the UE. The UE determines a second subframe for the UE to enter an active mode of processing for a reception of a grant, the second subframe is subsequent to the first subframe and prior to a next onDuration. The UE initiates an active mode of processing for the reception of the grant during the second subframe.

摘要： Methods and apparatuses to determine a frequency adjustment in a mobile wireless device are disclosed. A method includes determining a coarse frequency error estimate and multiple fine frequency error estimates; selecting at least one candidate fine frequency error estimate having a frequency value closest to a corresponding frequency value for the coarse frequency error estimate; and determining a frequency adjustment based on a combination of the coarse frequency error estimate and the selected at least one candidate fine frequency error estimate. In an embodiment, the method further includes calculating a confidence metric for the coarse frequency error estimate; when the confidence metric exceeds a threshold value, determining the frequency adjustment based on the candidate fine frequency error estimate; otherwise, determining the frequency adjustment based on a fine frequency error estimate in the plurality of fine frequency error estimates closest to a most recent previous fine frequency error estimate.

摘要： Adaptive neighboring cell measurement scaling by a wireless user equipment (UE) device. The UE may operate alternately in active and inactive states in a periodic manner according to DRX cycle timing for each of a plurality of DRX cycles. Paging messages may be checked for while in the active state during each DRX cycle. If a paging message is received, it may be decoded using a joint detection technique. The UE may adaptively determine whether or not to perform neighboring cell measurements during at least a subset of the DRX cycles, and perform neighboring cell measurements according to the adaptive determination. The adaptive determination may be based on one or more of joint detection of paging messages, one or more previous cell measurements, or an amount of motion of the UE.

摘要： Performing measurement of a first RAT while connected to a second RAT. The UE may initially communicate with a base station of the second RAT. While maintaining a connection to the base station of the first RAT, the UE may perform base station measurement of the first RAT (e.g., using a single radio of the UE). However, the measurement of the first RAT may be influenced by various factors, such as signal quality metrics of the second RAT. For example, if signal quality metrics are high for the second RAT, measurement of the first RAT may not be desirable, e.g., for battery life reasons.

摘要： Methods and apparatus for correcting quantization errors in signal reception based on estimated network loading including solutions for preserving cellular network performance in low noise, high interference environments. In one embodiment, a data channel is amplified with respect to other signals based on network load during periods of relatively low network utilization. Dynamic modification of the data channel's power level is configured to overcome quantization errors, rather than the true noise floor (which is insignificant in low noise environments). Such solutions provide both the fidelity necessary to enable high degrees of unwanted signaling rejection, while still preserving data channel quality.
