Abstract

Presented are systems, methods, apparatuses, or computer-readable media for information transfer in integrated access and backhaul (IAB) system and apparatus. A first network node may receive a first message including F1 control plane (F1-C) related traffic from a network function. The first network node can send a second message comprising the F1-C related traffic to a second network node.

  12. 12 . A non-transitory computer readable storage medium storing instructions, which when executed by one or more processors can cause the one or more processors to perform the method of claim 1 .
  13. 13 . A device comprising at least one processor configured to implement the method of claim 1 .
  14. 14 . The method of claim 11 , wherein the network function receives a message including the F1-C related traffic from a third network node.
  15. 15 . The method of claim 14 , wherein at least one of: the message is a new generation application protocol (NGAP) message, the message includes destination information, or the third network node receives the destination information from the first network node or the network function.
  16. 16 . The method of claim 14 , wherein at least one of: the message is a user equipment (UE) associated message that is associated with the second network node, or the message includes at least one of: an access and mobility management function (AMF) user equipment (UE) new generation application protocol (NGAP) identifier (ID) or a radio access network (RAN) UE NGAP ID.
  17. 17 . The method of claim 11 , wherein at least one of: the first message is a new generation application protocol (NGAP) message, or the first message includes destination information.
  18. 18 . The method of claim 11 , wherein at least one of: the second message is a radio resource control (RRC) message, or the second message includes destination information.
  19. 19 . A non-transitory computer readable storage medium storing instructions, which when executed by one or more processors can cause the one or more processors to perform the method of claim 11 .

Description

TECHNICAL FIELD The disclosure relates generally to wireless communications, including but not limited to systems and methods for information transfer in integrated access and backhaul (IAB) system and apparatus. 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 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. It is understood, however, that these embodiments are presented by way of example and are not limiting, and it will be apparent to those of ordinary skill in the art who read the present disclosure that various modifications to the disclosed embodiments can be made while remaining within the scope of this disclosure. At least one aspect is directed to a system, a method, an apparatus, or a computer-readable medium for transferring information in an IAB system. A first network node (e.g., target donor) can receive/obtain/collect/acquire a first message/information/signal from a network function (e.g., access and mobility management function (AMF)). The first message can include F1 control plane (F1-C) related traffic. The first network node can send/transmit/provide/signal/communicate a second message to a second network node (e.g., mobile-IAB node). The second message can comprises the F1-C related traffic. In various arrangements, the network function can receive a message including the F1-C related traffic from a third network node (e.g., source donor). In some implementations, at least one of: the message can be a new generation application protocol (NGAP) message, the message can include destination information, and/or the third network node can receive the destination information from the first network node or the network function. In some arrangements, at least one of: the message can be a user equipment (UE) associated message that is associated with the second network node, and/or the message can include at least one of: AMF UE new generation application protocol (NGAP) identifier (ID) and/or a radio access network (RAN) UE NGAP ID. In certain implementations, at least one of: the first message can be a NGAP message, and/or the first message can include destination information. In some aspects, at least one of: the second message can be a radio resource control (RRC) message, and/or the second message includes destination information. In some cases, a mobile termination (MT) of the second network node may send the F1-C related traffic, from the second message, to a distributed unit (DU) of the second network node. In some arrangements, at least one of: the second message can be an F1AP message, and/or the second message can include destination information. In some implementations, a first DU of the second network node can send the F1-C related traffic, from the second message, to another DU of the second network node. In some arrangements, the destination information can comprise at least one of: a DU identity, a backhaul adaptation protocol (BAP) address, a centralized unit (CU) identity, a next generation NodeB (gNB) identity (e.g., base station (BS) or wireless communication node), a source logical DU indication, a logical DU identity, and/or an internet protocol (IP) address. At least one aspect is directed to a system, a method, an apparatus, or a computer-readable medium for transferring information in an IAB system. A network function (e.g., AMF) can send a first message to a first network node (e.g., target donor). The first message can include F1 control plane (F1-C) related traffic. The first network node can send a second message to a second network node (e.g., mobile-IAB node). The second message can comprise the F1-C related traffic.
