Description

PRE-PAGING FOR DEEP COVERAGE SCENARIOS CROSS-REFERENCE TO RELATED APPLICATION [0001] This application claims priority to U.S. Patent Application No. 18/459,403, filed August 31, 2023, which is assigned to the assignee hereof and hereby expressly incorporated by reference in its entirety as if fully set forth below and for all applicable purposes. BACKGROUND Field of the Disclosure [0002] Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for reaching a user device located in a limited coverage zone of a wireless communications network. Description of Related Art [0003] 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. [0004] 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 [0005] One aspect provides a method for wireless communications at a user equipment (UE). The method includes receiving signaling configuring the UE with a first set of resources for monitoring for paging message and a second set of resources for monitoring for pre-paging messages; monitoring the second set of resources for a prepaging message if one or more conditions are met; and performing one or more actions in response to detecting a pre-paging message. [0006] Another aspect provides a method for wireless communications at a network entity. The method includes transmitting a pre-paging message to a user equipment (UE) on a second set of resources if one or more conditions are met, wherein the second set of resources is different than a first set of resources for transmitting a paging message to the UE; and performing one or more actions after transmitting the pre-paging message. [0007] Other aspects provide: an apparatus operable, configured, or otherwise adapted to perform any one or more of the aforementioned methods and/or those described elsewhere herein; a non-transitory, computer-readable media comprising instructions that, when executed by a processor of an apparatus, cause the apparatus to perform the aforementioned methods as well as those described elsewhere herein; a computer program product embodied on a computer-readable storage medium comprising code for performing the aforementioned methods as well as those described elsewhere herein; and/or an apparatus comprising means for performing the aforementioned methods as well as those described elsewhere herein.
