The present specification provides a method for performing an integrated access and backhaul (IAB) operation performed by a node in a wireless communication system, and an apparatus therefor, the method comprising: performing an initial access operation with another node; receiving, from the other node, at least one piece of timing advance (TA) information or T delta information, wherein downlink transmission timing of the node and uplink transmission timing of the node are aligned or determined on the basis of the at least one piece of TA information or T_delta information; and performing the IAB operation on the basis of the downlink transmission timing and the uplink transmission timing.

A Shared Cell (SC) Controller uses deployment information, radio resource utilization measurements, cell load measurements, signal quality measurement, operator's policies and radio capabilities to make decisions on system configuration, re-configuration, and channel allocation related to the Shared Cell groups. The SC Controller may also use artificial intelligence/machine learning to predict future system state when making decisions on system configuration and channel allocation. The SC Controller can be implemented in the context of using a CBRS system, the ORAN architecture, and the Shared Cell group of Radio Units (RUs). SC Controller can be implemented as part of the Non-Real Time Radio Intelligent Controller (Non-RT RIC). The SC Controller interfaces with the Citizens Broadband Radio Service Device (CBSD) Controller, and the SC Controller sends the Shared Cell group information to the O-RU Controller so that the O-RU Controller can configure the radio components.

A base station transmits a layered data signal to multiple devices that are in close proximity to each other where the layered data signal includes at least first data on a first data layer directed to a first device and second data on a second data layer directed to a second device. The base station also transmits a single control message to both devices where the control message comprises location dependent control information directed to both devices. The control message also comprises data layer control information arranged in multiple fields where data layer control information in a field is associated with a device and allows the associated device to recover the data from a data layer assigned to the device.

A donor communication station transmits a unicast transmission comprising a plurality of device data sets where each device data set directed to each of a plurality of user equipment (UE) devices. A relay node receives the unicast transmission and retransmits the data sets in a broadcast transmission over a broadcast communication channel to the plurality of UE devices. In one example, the donor communication station encodes data for multiple user equipment (UE) devices by applying broadcast encoding to the data for each device before applying outer encoding to the data. The dual encoded data is transmitted to the relay node over a dedicated channel. The relay node applies outer decoding to the dual encoded data to retrieve the broadcast encoded data. The relay node then transmits the broadcast encoded device data in a broadcast transmission without outer encoding.

Systems and methods for redirecting Radio Resource Control (RRC) messages in a wireless system that uses Central Unit (CU)/Distributed Unit (DU) splitting and either network sharing or network slicing are disclosed. In some embodiments, a method performed by a shared Distributed Unit (DU) comprises receiving a RRC message from a User Equipment (UE) and sending a first DU-to-Central Unit (CU) message to a first CU, where the first DU-to-CU message comprises the RRC message. The method further comprises either obtaining an indication that the first CU is a wrong CU for the RRC message or determining that the first CU is a wrong CU for the RRC message. The method further comprises sending another DU-to-CU message to a second CU, where the other DU-to-CU message comprises the RRC message or a RRC message related to the RRC message.

A network access method includes transmitting a request for acquiring shared network information to a shared server if a mobile communication terminal detects that a network identification of a PLMN of a visited place does not exist in a local memory of the mobile communication terminal; receiving the shared network information which the shared server transmits in response to the request, and acquiring the network identification of the PLMN of the visited place from the shared network information; adding the network identification of the PLMN of the visited place to an EPLMN list by the mobile communication terminal; and accessing a network according to the EPLMN list.

A method and apparatus for transmitting a local home network identity (LHN ID) in a wireless communication system is provided. A first evolved NodeB (eNB) transmits an X2 Setup Request message including a LHN ID of the first eNB to a second eNB, and receives an X2 Setup Response message including a LHN ID of the second eNB from the second eNB. The first eNB may determine whether or not to trigger a secondary eNB (SeNB) addition procedure according to the LHN ID of the second eNB. When it is determined that the LHN ID of the second eNB is the same as the LHN ID of the first eNB, the first eNB may trigger the SeNB addition procedure.

A communication device for handling channel access in an unlicensed band comprises a storage device for storing instructions and a processing circuit coupled to the storage device. The processing circuit is configured to execute the instructions stored in the storage device. The instructions comprise receiving an uplink (UL) grant from a network, wherein the UL grant indicates the communication device to perform an UL transmission in a transmission time interval (TTI); performing a listen-before-talk (LBT) procedure on a first carrier in response to the UL grant; and aborting the LBT procedure, when the communication device senses the first carrier to be busy before the TTI according to the LBT procedure.

A first network node of a first frequency layer, acquires (201) information on services that are offered by a second network node at a second, different frequency layer. The second network node is within the coverage area of the first network node. The first network node broadcasts (202) a service advertisement message to at least one terminal device (UE) for advertising the services offered by the second network node at the second frequency layer.

The present invention claims a TR069 protocol management method oriented to a WIA-PA network, where a traditional TR069 network management system architecture is improved to extend a TR069 protocol only oriented to Internet terminal device management in an initial design from the Internet to a WIA-PA wireless sensor network; a session connection interaction process between an ACS and a CPE is expanded to establish a session connection between the ACS and a WIA-PA network node; a virtual device mechanism is designed by taking a WIA-PA network gateway as the CPE to store a TR069 data model and proxy device information corresponding to a WIA-PA data model and implement the TR069 protocol to manage the WIA-PA network node in a manner as simple and transparent as that for an interaction between the ACS and the common CPE; a management data model mapping mechanism is designed to establish a correlation from the WIA-PA data model described in TR069 to a standard WIA-PA data model; and a protocol conversion interlace is designed to implement the conversion between a TR069 RPC method and a WIA-PA network management command frame. The TR069 protocol management method has a good reference value for the implementation of the M2M management of the whole network as well as the application and development of the TR069 protocol oriented to the wireless sensor network.
