Abstract: A method performed by a first network node in a communication system for supporting ultra-reliable and low latency communication (URLLC) in open radio access network (O-RAN) is provided. The method includes receiving a control plane message of a first communication from a second network node, wherein the control plane message comprises preemption type information and information related to the first communication preempting resource layers of a second communication, and determining resources for the first communication based on the control plane message.

Abstract: The disclosure relates to a method performed by a network node, comprising acquiring cell capacity information of a plurality of cells corresponding to a Distributed Unit (DU) of a base station. The method comprises determining cell capacity summations corresponding to the DU based on each cell corresponding to different cell capacities, based on the cell capacity information. The method comprises determining a predicted cell capacity of the plurality of cells based on the cell capacity summations, for the base station allocating a cell capacity with respect to each of the plurality of cells according to the predicted cell capacity.

Abstract: Embodiments of the disclosure provide a communication method and apparatus for an open radio access network (O-RAN), an electronic device, and a computer-readable storage medium, relating to communication. The method comprises: determining, by an O-RAN distributed unit (O-DU), for a periodic or semi-persistent channel or signal, that that a trigger condition for a first control-plane message is satisfied; and transmitting, by the O-DU, a first control-plane message to an O-RAN radio unit (O-RU), the first control-plane message indicating a first endpoint in the O-RU to perform an operation related to first information, the O-RU configured to periodically control receiving uplink air interface data or processing downlink user-plane messages based on the first information. In various embodiments of the disclosure, periodically transmitting control-plane messages is avoided and the message load of the fronthaul interface is thus effectively reduced. Therefore, for channels or signals with periodic or semi-persistent characteristics, a defect that loads of the fronthaul interface could not be reduced by the existing solutions can be addressed.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Disclosed are a method and an apparatus for a congestion control in wireless communication, the method includes: a network side node receives a congestion related information reported by a UE or UEs, determines a congestion control range or congestion control ranges based on the congestion related information reported by the UE or UEs and transmits determined congestion control range information to a UE or UEs; the UE or UEs receives the congestion control range information transmitted by the network side node, determines whether the UE or UEs is/are within the congestion control range according to the received congestion control range information, and performs the congestion control when the UE or UEs is/are within the congestion control range. The congestion related information is reported to the network side through the UE or UEs such that the network side can more accurately grasp the global congestion situation, thus facilitating the formulation of more optimized congestion control strategy and meanwhile reducing information exchange between the UEs, reducing the resource consumption of the PC5 interface, and reducing the possibility of the occurrence of the congestion.
