Claims (12)

1 . An apparatus for wireless communication, comprising: at least one transceiver; one or more memories comprising processor-executable instructions; and one or more processors configured to execute the processor-executable instructions to cause the apparatus to: receive, via the at least one transceiver, a mobile terminated (MT) paging message; and perform one or more actions to prioritize processing the MT paging message when one or more reselection criteria for performing a reselection procedure from a first cell to a second cell are met, wherein, to perform the one or more actions, the one or more processors are configured to cause the apparatus to at least one of: buffer the MT paging message, initiate a timer in conjunction with buffering the MT paging message, and process the buffered MT paging message after failure of the reselection procedure based on the timer; or prioritize processing the MT paging message over performing the reselection procedure, wherein to prioritize processing the MT paging message over performing the reselection procedure, the one or more processors are further configured to cause the apparatus to: evaluate RF conditions in both the first cell and the second cell, wherein to evaluate the RF conditions in both the first cell and the second cell, the one or more processors are configured to cause the apparatus to compare a first RF metric for the first cell with a second RF metric for the second cell; and process the MT paging message and terminate the reselection procedure, when the first RF metric for the first cell is within a first threshold value of the RF second metric for the second cell.
2 . The apparatus of claim 1 , wherein: the first cell is associated with a first radio access technology (RAT); and the second cell is associated with a second RAT.

6 . The apparatus of claim 1 , wherein the first RF metric and the second RF metric are at or below a third threshold value.
7 . The apparatus of claim 1 , wherein the one or more processors are further configured to cause the apparatus to: maintain a counter to track a quantity of times a reselection procedure failure has coincided with reception of an MT paging message.
8 . The apparatus of claim 7 , wherein the one or more processors are configured to cause the apparatus to prioritize processing the MT paging message over performing the reselection procedure when the counter is at or above a target value.
9 . The apparatus of claim 1 , wherein the one or more processors are configured to cause the apparatus to: process the buffered MT paging message after failure of the reselection procedure while the timer is not expired; or discard the buffered MT paging message when the reselection procedure is successful or when the timer has expired.
10 . The apparatus of claim 1 , wherein the timer is initiated to a configurable value.
11 . A method for wireless communications by a user equipment (UE), comprising: receiving a mobile terminated (MT) paging message; and performing one or more actions to prioritize processing the MT paging message when one or more reselection criteria for performing a reselection procedure from a first cell to a second cell are met, wherein performing the one or more actions comprises at least one of: buffering the MT paging message, initiating a timer in conjunction with buffering the MT paging message, and processing the buffered MT paging message after failure of the reselection procedure based on the timer; or prioritizing processing the MT paging message over performing the reselection procedure, wherein to prioritizing processing the MT paging message over performing the reselection procedure, comprises: evaluating RF conditions in both the first cell and the second cell, wherein evaluating the RF conditions in both the first cell and the second cell comprises comparing a first RF metric for the first cell with a second RF metric for the second cell; and processing the MT paging message and terminating the reselection procedure, when the first RF metric for the first cell is within a first threshold value of the RF second metric for the second cell.
12 . The method of claim 11 , wherein at least one of: the first cell is associated with a first radio access technology (RAT) and the second cell is associated with a second RAT; one of the first cell and the second cell uses time division duplexing (TDD) and the other of the first cell and the second cell uses frequency division duplexing (FDD); or one of the first cell and the second cell operates within a first frequency range (FR) and the other of the first cell and the second cell operates within a second FR.

Description

BACKGROUND Field of the Disclosure Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for processing paging messages. Description of Related Art Wireless communications systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, broadcasts, or other similar types of services. These wireless communications systems may employ multiple-access technologies capable of supporting communications with multiple users by sharing available wireless communications system resources with those users. Although wireless communications systems have made great technological advancements over many years, challenges still exist. For example, complex and dynamic environments can still attenuate or block signals between wireless transmitters and wireless receivers. Accordingly, there is a continuous desire to improve the technical performance of wireless communications systems, including, for example: improving speed and data carrying capacity of communications, improving efficiency of the use of shared communications mediums, reducing power used by transmitters and receivers while performing communications, improving reliability of wireless communications, avoiding redundant transmissions and/or receptions and related processing, improving the coverage area of wireless communications, increasing the number and types of devices that can access wireless communications systems, increasing the ability for different types of devices to intercommunicate, increasing the number and type of wireless communications mediums available for use, and the like. Consequently, there exists a need for further improvements in wireless communications systems to overcome the aforementioned technical challenges and others. SUMMARY One aspect provides a method for wireless communications at a user equipment (UE). The method includes obtaining a mobile terminated (MT) paging message; and performing one or more actions to prioritize processing the MT paging message when one or more reselection criteria for performing a reselection procedure from a first cell to a second cell are met.

DETAILED DESCRIPTION Aspects of the present disclosure provide apparatuses, methods, processing systems, and computer-readable mediums for processing paging messages. Paging generally refers to a mechanism in which a network informs a user equipment (UE) of available information for the UE (e.g., emergency information or a phone call). In certain scenarios, paging messages may be successfully received by a UE, but not processed. One such scenario is if a paging message is received during a cell reselection procedure. Typically, in such cases, the cell reselection procedure may be prioritized and the paging message discarded. Unfortunately, in the event the reselection procedure is processed,
