Description

SYSTEMS AND METHODS FOR DETERMINING AN ACCESS TECHNICAL FIELD The disclosure relates generally to wireless communications, including but not limited to systems and methods for determining an access. BACKGROUND The standardization organization Third Generation Partnership Project (3GPP) is currently in the process of specifying a new Radio Interface called 5G New Radio (5G NR) as well as a Next Generation Packet Core Network (NG-CN or NGC) . The 5G NR will have three main components: a 5G Access Network (5G-AN) , a 5G Core Network (5GC) , and a User Equipment (UE) . In order to facilitate the enablement of different data services and requirements, the elements of the 5GC, also called Network Functions, have been simplified with some of them being software based, and some being hardware based, so that they could be adapted according to need. SUMMARY The example embodiments disclosed herein are directed to solving the issues relating to one or more of the problems presented in the prior art, as well as providing additional features that will become readily apparent by reference to the following detailed description when taken in conjunction with the accompany drawings. In accordance with various embodiments, example systems, methods, devices and computer program products are disclosed herein.

At least one aspect is directed to a system, method, apparatus, or a computer-readable medium of the following. A second wireless communication node (e.g., a smart rely (SR) ) determine information related to access according to a received first message from a first wireless communication node (e.g., a base station (BS) ) or according to a rule. The second wireless communication node may determine a third wireless communication node to access according to the information related to access. The second wireless communication node may access to the third wireless communication node, if any.
