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： This disclosure relates to techniques for opportunistically depowering receiver chains of a wireless device. Based on control information, a device may determine whether the current number of active receiver chains can be reduced while maintaining a target achievable code rate for a period of data reception associated with the control information. Additionally, the device may generate and use a lookup table to determine whether to depower receiver chains, and which receiver chains to depower.

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.
摘要翻译： 在连接到第二RAT时执行第一RAT的测量。 UE可以初始地与第二RAT的基站进行通信。 在保持与第一RAT的基站的连接的同时，UE可以执行第一RAT的基站测量（例如，使用UE的单个无线电）。 然而，第一RAT的测量可能受各种因素的影响，例如第二RAT的信号质量度量。 例如，如果第二RAT的信号质量度量高，则可能不期望第一RAT的测量，例如，由于电池寿命的原因。

摘要： This disclosure relates to techniques for estimating baseband power consumption and using the baseband power consumption estimation to select baseband operation features. According to some embodiments, one or more baseband power consumption modifiers occurring during an estimation window may be identified. Baseband power consumption of the wireless device during the estimation window may be estimated based on the identified baseband power consumption modifiers occurring during the estimation window. Baseband data throughput of the wireless device during the estimation window may also be estimated. One or more baseband operation characteristics may be selected based at least in part on the estimated baseband power consumption during the estimation window, possibly in conjunction with the estimated baseband data throughput during the estimation window, current wireless medium conditions, and/or other considerations.

摘要： This disclosure relates to techniques for enabling a cellular network to more efficiently announce special network capabilities to UE's in its coverage area. The special network capabilities may be specific to a first class of UE devices and/or may be outside of the relevant telecommunication standard used by the cellular network. The base station may transmit a dummy System Information Block-1 (SIB-1), wherein the dummy system information block is broadcast separately from regular system information block 1's (SIB-1's).

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.
