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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a plurality of beams, from a base station, wherein the plurality of beams are associated with a corresponding plurality of monitoring occasions for a first subscription of the UE. The UE may determine whether a monitoring occasion for a second subscription of the UE collides with one or more of the plurality of monitoring occasions, for the first subscription of the UE, corresponding with the plurality of beams. The UE may transmit, to the base station, an indication of a selected beam, from the plurality of beams, based at least in part on the measuring and the determining.

Abstract: A user equipment may, based on a tuneaway, start suspend a first timer and/or deactivate a first counter and may, based on a tuneback, resume the first timer and/or activate the first counter. The first timer and first counter may be configured to be used to determine that a sufficiently large number of sufficiently closely timed beam failure indications have been received and, in response to that determination, initiate an access procedure. A user equipment may also identify an overlap of a timing of at least one radio access technology event and a timing of a tuneaway gap and may, based on the identified overlap of the timing of at least one radio access technology event and the timing of the tuneaway gap, modify the timing of the at least one radio access technology event or the timing of the tuneaway gap.

Abstract: Access terminals are adapted to facilitate discontinuous transmission (DTX). According to one example, an access terminal determines to disable DTX, such that a continuous reverse link transmission may occur, in a fashion such as not to interfere with the operation of a Frame Early Termination operation utilized in CDMA 1× technology. As one example, the access terminal may cease the utilization of DTX in accordance with a performance metric of a wireless communication network. The performance metric may be a forward link power control setpoint of a base station, a number of quasi-orthogonal function sets being utilized at the base station, a number of frame erasures corresponding to a forward link transmission from the base station, or any other suitable measurable parameter of the network performance. Other aspects, embodiments, and features are also claimed and described.
