A base station management device is provided in the invention. The base station management device includes a Non-Real Time (Non-RT) Radio-Access-Network Intelligent Controller (RIC) and a management device. The Non-RT RIC communicates with applications through a first communication interface. The management device manages a plurality of base stations, communicates with the Non-RT RIC through a second communication interface, and registers a first application and a second application through the Non-RT RIC. The management device detects the plurality of base stations through the first application to determine whether to update the parameter information of the plurality of base stations through the second application.

Techniques that provide link auto-negotiation between a radio equipment controller (REC) and a radio equipment (RE) are described herein. In one embodiment, a method includes performing, by a proxy master, a Common Public Radio Interface (CPRI) Layer 1 (L1) link auto-negotiation with a RE to achieve a L1 synchronization between the proxy master and the RE at a link bit rate; communicating the link bit rate from the proxy master to a proxy slave; performing, by the proxy slave, a CPRI L1 link auto-negotiation with a REC to determine whether a L1 synchronization between the proxy slave and the REC is achieved, wherein if the L1 synchronization is achieved, the link bit rate is a common matching link bit rate achieved; and upon the common matching link bit rate being achieved, establishing a CPRI link between the REC and the RE using the common matching link bit rate.

One object is to provide a radio base station and a communication control method that can realize appropriate control on a user device even when a function of an upper layer such as MAC scheduler and a function of a radio physical layer are mounted separately. A communication control method according to the present invention is implemented in a radio base station (200) including a remote device (260) and a central aggregation device (210) and that performs radio communication with a user device (300). The communication control method includes transmitting including the central aggregation device (210) transmitting to the remote device (260) paging information that is information used for performing paging on the user device (300), and performing including the remote device (260) setting a downlink physical channel based on the paging information received from the central aggregation device (210) and performing the paging.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first node may transmit, to a second node, a first message providing a first indication of integrated access and backhaul (IAB) capability. The first node may receive, from the second node and in response to the first message, a second message providing a second indication of IAB capability. The first node may establish an IAB capable connection with the second node based at least in part on the first message and the second message. Numerous other aspects are provided.

An O-RAN distributed unit (O-DU) receives, from an intermediate device provided on a fronthaul, processing time information indicating a processing time in the intermediate device. The O-DU decides capability information set for the intermediate device based on at least the processing time information and transmits the decided capability information to the intermediate device.
