Abstract: Aspects of the present disclosure relate to apparatuses and methods for performing adaptive receive-diversity (RxD) to improve power consumption using multiple antennas/receivers. In one aspect, a first receive-diversity (RxD) state is enabled at an access terminal utilizing two receive chains for a communication link. Link quality metrics corresponding to the communication link are determined. The access terminal selectively switches from the first RxD state to a second RxD state utilizing three or more receive chains dependent upon the link quality metrics, such that the energy per bit of the second RxD state is more energy efficient than the energy per bit of the first RxD state.

Abstract: Access terminals are adapted to facilitate discontinuous transmission (DTX). According to one example, an access terminal can employ a short timescale DTX mode and a long timescale DTX mode independent of one another. The access terminal can determine whether a first set of predetermined factors are present. When the first set of factors are determined to be present, the access terminal may enable a short timescale DTX mode, independent of whether a long timescale DTX mode is enabled or not. A determination may also be made whether a second set of predetermined factors are present. When the second set of predetermined factors are determined to be present, the access terminal may enable a long timescale DTX mode, independent of whether the short timescale DTX mode is enabled or not. Other aspects, embodiments, and features are also included.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a user equipment (UE) identifying a priority scheme for a set of signals including a first set of synchronization signal block (SSB) signals associated with a first frequency range, a second set of SSB signals associated with a second frequency range, and a paging signal associated with the first frequency range. The UE may then monitor, via a narrowband processor of the UE and based on the priority scheme, a set of time resources for one or more of the first set of SSB signals, the second set of SSB signals, or the paging signal. The narrowband processor may be configured to process signals received via the first frequency range and the second frequency range.

Abstract: Aspects of the present disclosure provide wireless communication devices and methods configured to operate with multiple active connections. A user equipment establishes a first active connection associated with a first subscription. The user equipment also establishes a second active connection, simultaneous to the first active connection, associated with a second subscription. The user equipment provides modem information corresponding to connection qualities of the first active connection and second active connection, to an operating system of the user equipment. Furthermore, the user equipment mitigates contention between the first active connection and second active connection by degrading at least one of the first active connection or second active connection in accordance with a decision given by the operating system based on the modem information.

Abstract: Aspects of the present disclosure relate to a multimode user equipment (UE) that when suffering a power crunch, can intelligently reselect to another RAT to extend the battery life of the UE. The reselected RAT has a lower specified maximum transmit power relative to the currently attached RAT. Therefore, the UE may reduce its battery drain to extend its service time per charge when a call is made utilizing the reselected RAT. The UE intelligently selects the RAT that will likely consume less uplink transmit power to communicate with a base station in order to conserve battery power in a poor coverage area, when the UE is experiencing a power crunch condition.

Abstract translation: 本公开的方面涉及多模式用户设备（UE），当遭受电力紧张时，可以智能地重新选择另一个RAT以延长UE的电池寿命。 重新选择的RAT相对于当前连接的RAT具有较低的指定的最大发射功率。 因此，当利用重新选择的RAT进行呼叫时，UE可以减少其电池消耗以延长其每次充电的服务时间。 当UE正在经历电力紧急状态时，UE智能地选择可能消耗较少上行链路发射功率以与基站进行通信的RAT，以便节省较差覆盖区域中的电池功率。

Abstract: Apparatus and methods are provided to enable a ratcheting of uplink transmit power at an access terminal in a wireless communication network, such that the transmit power is maintained between an upper threshold and a lower threshold. Here, the decision whether to ratchet the power may be based on one or both of the open-loop transmit power and/or the closed-loop transmit power. Moreover, the decision whether to ratchet the transmit power may be based on the power per carrier in a multi-carrier wireless communication network. Other aspects, embodiments, and features are also claimed and described.

Abstract: Aspects of the present disclosure relate to wireless communication devices and methods configured to operate with multiple communication protocols in tune-away operations. Some aspects of the present disclosure may improve the legacy tune-away operations at an access terminal. An access terminal establishes a call utilizing a first communication protocol, tunes away from the call to receive cell signaling utilizing a second communication protocol, and tunes back to the call utilizing the first communication protocol. Following the tuning back, during a first predetermined number of subframes and if the size of a reverse link (RL) packet is smaller than a first packet size and larger than a second packet size, the access terminal forces the RL packet to be a low latency (LoLat) packet.
