Abstract

Various aspects of the present disclosure relate to transmitting a first request message comprising a first set of parameters. Aspects of the present disclosure may relate to receiving a first response message comprising an indication that a device is unreachable. Aspects of the present disclosure may relate to resetting a sequence number (SQN) and a device profile for the device in response to the first response message. Aspects of the present disclosure may relate to transmitting a second request message comprising a second set of parameters, wherein the second set of parameters comprises a default identifier (ID) of the device, a nonce, and the SQN. Aspects of the present disclosure may relate to receiving a second response message from the device comprising a result based on the default ID.

Description

TECHNICAL FIELD The present disclosure relates to wireless communications, and more specifically to techniques for synchronizing devices in case of a temporary identifier (ID) mismatch. BACKGROUND A wireless communications system may include one or multiple network communication devices, such as base stations, which may support wireless communications for one or multiple user communication devices, which may be otherwise known as user equipment (UE), or other suitable terminology. The wireless communications system may support wireless communications with one or multiple user communication devices by utilizing resources of the wireless communication system (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers, or the like). Additionally, the wireless communications system may support wireless communications across various radio access technologies (RATs) including third generation (3G) radio access technology, fourth generation (4G) radio access technology, fifth generation (5G) radio access technology, among other suitable radio access technologies beyond 5G (e.g., sixth generation (6G)). SUMMARY An article “a” before an element is unrestricted and understood to refer to “at least one” of those elements or “one or more” of those elements. The terms “a,” “at least one,” “one or more,” and “at least one of one or more” may be interchangeable. As used herein, including in the claims, “or” as used in a list of items (e.g., a list of items prefaced by a phrase such as “at least one of” or “one or more of” or “one or both of) indicates an inclusive list such that, for example, a list of at least one of A, B, or C means A or B or C or AB or AC or BC or ABC (i.e., A and B and C). Also, as used herein, the phrase “based on” shall not be construed as a reference to a closed set of conditions. For example, an example step that is described as “based on condition A” may be based on both a condition A and a condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase “based on” shall be construed in the same manner as the phrase “based at least in part on.” Further, as used herein, including in the claims, a “set” may include one or more elements. Some implementations of the method and apparatuses described herein may include means for transmitting a first request message comprising a first set of parameters. The method and apparatuses described herein may include means for receiving a first response message comprising an indication that a device is unreachable. The method and apparatuses described herein may include means for resetting a sequence number (SQN) and a device profile for the device in response to the first response message. The method and apparatuses described herein may include means for transmitting a second request message comprising a second set of parameters, wherein the second set of parameters comprises a default identifier (ID) of the device, a nonce, and the SQN. The method and apparatuses described herein may include means for receiving a second response message from the device comprising a result based on the default ID. In some implementations of the method and apparatuses described herein may include means for receiving a first request message including a first set of parameters. The method and apparatuses described herein may include means for determining that the first set of parameters includes a default ID of the UE and a reset SQN. The method and apparatuses described herein may include means for generating a temporary ID based at least in part on the first set of parameters. The method and apparatuses described herein may include means for transmitting a response message including at least an expected result based on the default ID. The method and apparatuses described herein may include means for receiving a second request message including a second set of parameters, where the second set of parameters includes the temporary ID and a set of command parameters.
