Abstract: Certain aspects of the present disclosure propose methods for determining power level of one or more transmitters based on a power level of a primary transmitter when the transmitters are located in close proximity of each other. The power levels may be determined such that a combined power of all the transmitters is compliant with regulatory radio frequency (RF) safety requirements. For certain aspects, power level of the lower priority transmitters may be determined utilizing one or more look-up tables. For another aspect, power level of the lower priority transmitters may be calculated using an algorithm based on the power level of the priority transmitter. In aspects, the power level of lower priority transmitters and the time duration for which the transmitters are active may be selected dynamically so that the time averaged power of the transmitters for a defined period of time falls below the RF exposure limit.

Abstract: Device-to-device operations are scheduled based on receive and transmit pools that may have a conflict in time domain. In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus for resolving time domain conflict in device-to-device communication are provided. The apparatus may compute a first block rate metric for a first device-to-device communication on a first frequency and a second block rate metric for a second device-to-device communication on a second frequency. The apparatus may detect a time-domain conflict between the first device-to-device communication on the first frequency and the second device-to-device communication on the second frequency. The apparatus may prioritize the first device-to-device communication on the first frequency and the second device-to-device communication on the second frequency based on the first block rate metric and the second block rate metric.

Abstract: User equipment (UE) based pseudo-reselection occurs from a first wireless cell to a second wireless cell. A UE autonomously discovers candidate reselection frequencies and autonomously sets reselection thresholds. The UE perform cell reselection based on the discovered candidate cell reselection frequencies and the autonomously set thresholds.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for sending fast negative acknowledgements (NACKs) after a user equipment (UE) tunes back to a first network after tuning away from the first network. The UE may determine that a trigger event has occurred, and in response to the determination, modify a NACK timing configuration from a default configuration. Modifying the NACK timing configuration may include using an aggressive NACK timing configuration for a configurable period of time, in response to detecting a trigger event. The trigger event may include detecting missed packets after a tune back, unavailability of sufficient memory to hold packets until a gap created by missed packets may be filled, or tuning back to a network.

Abstract translation: 本公开的某些方面涉及用于在从第一网络调谐之后用户设备（UE）回调到第一网络之后发送快速否定确认（NACK）的方法和装置。 UE可以确定已经发生触发事件，并且响应于该确定，从默认配置修改NACK定时配置。 修改NACK定时配置可以包括响应于检测到触发事件而在可配置的时间段内使用积极的NACK定时配置。 触发事件可以包括在回调之后检测错过的分组，不可用的足够的存储器来保存分组，直到由丢失的分组创建的间隙可能被填充或者回调到网络。

Abstract: Methods, devices, and systems embodiments enable management of service preemption of at least one of a plurality of subscriptions that utilize a plurality of radio-frequency (RF) chains on a multi-Subscriber-Identity-Module, multi-active communication device in a manner that can accommodate a variety of different RF hardware components and configurations. Various embodiments provide methods implemented by a processor to manage service preemption. In response to detecting that a service of a second subscription initiated on a first RF chain is or will preempt a service of a first subscription that is also serviced by the first RF chain, the processor may determine whether there is a similar service on a second RF chain that may be used as a substitute for the first subscription's preempted service and, when available, the processor may configure the first subscription to begin utilizing the substitute service until the first RF chain is available.
