In order to start transmission of downlink data to an RLC layer with an appropriate data amount from a base station that performs Packet Data Convergence Protocol (PDCP) layer processing to another base station that performs Radio Link Control (RLC) layer processing, a base station 100 (MN) includes: an information obtaining unit configured to obtain information for controlling a downlink data flow in a Radio Link Control (RLC) layer for a terminal apparatus 300; and a communication processing unit 143 configured to transmit, to a base station 200 (SN) performing processing for a PDCP layer for the terminal apparatus 300, the information for controlling the downlink data flow, before the base station 100 (MN) detects a correct random access channel access.

A primary access node adds a secondary access node to deliver wireless communication service to a User Equipment (UE). The primary access node comprises baseband circuitry and a radio. The radio wirelessly receives a measurement report from the UE that characterizes a radio metric for the secondary access node. The baseband circuitry determines insertion loss for the secondary access node and an add threshold for the secondary access node based on the insertion loss. The baseband circuitry determines an add value for the secondary access node based on the radio metric. When the add value exceeds the add threshold, the baseband circuitry transfers network signaling to the secondary access node to serve the UE and transfers user signaling to the UE over the radio. The UE attaches to the secondary access node and the secondary access node delivers the wireless communication service to the UE.

This disclosure describes systems, devices, and computer-implemented methods that facilitate the simultaneous transmission of subsets of user plane data to a telecommunications network via two or more uplink transmission paths. More specifically, a mobile device may detect user plane data within a buffer pool and in doing so, transmit a resource allocation request for the uplink transmission of the user plane data. In response, the mobile device may receive a set of control plane data associated with the uplink transmission via two or more uplink transmission paths. The mobile device may simultaneously transmit subsets of user plane data to the telecommunications network via multiple base station nodes, based at least in part on the control plane data.

A method and apparatus for load balancing. The method executed by a master base station for load balancing comprising: determining a load balancing group, wherein the load balancing group includes a plurality of secondary base stations; and sending a grouping information about the load balancing group to each secondary base station of the load balancing group. The method executed by a secondary base station of a load balancing group for load balancing comprising: receiving a grouping information about the load balancing group from a master base station; exchanging the load information with other secondary base stations of the load balancing group; selecting a target secondary base station from the other secondary base stations according to the load information of other secondary base stations; and forwarding at least a portion of load of the secondary base station to the target secondary base station.

Provided are a configuration method, apparatus, system and device for a data flow, and a computer medium. The configuration method for a data flow includes: when the first network element needs to offload part of QFs in a PDU Session to a second network element for transmission, a request message is sent to the second network element, where the request message carries an uplink interface address on a core network side; the second network element receives the request message sent by the first network element, and obtains, according to the request message, the uplink interface address on the core network side required for a QF offloaded to the second network element.

Methods and apparatuses are provided in a wireless communication system. A first message is transmitted, from a master base station, to a secondary base station, for requesting the secondary base station to allocate resources for a dual connectivity (DC) operation. A second message is received from the secondary base station, after transmitting the first message. A third message is transmitted to the secondary base station, after receiving the second message. The first message includes a quality of service (QoS) flow identifier (ID) and available data radio bearer (DRB) IDs. The second message includes the QoS flow ID and a DRB ID corresponding to the QoS flow ID. The third message includes tunnel information for the DRB ID including an Internet protocol (IP) address and a tunnel endpoint identifier (TEID).

Methods, systems, and devices for wireless communications are described. An integrated access and backhaul (IAB) node may include a first component for communications with a parent node and a second component for communications with a child node. The IAB node may perform a first channel access procedure for a first fixed frame period associated with the first component. The IAB node may perform a second channel access procedure for a second fixed frame period associated with the second component, the second fixed frame period staggered in time with respect to the first fixed frame period in accordance with an offset. The IAB node may communicate with one or more wireless devices during a first channel occupancy time associated with the first fixed frame period, during a second channel occupancy time associated with the second fixed frame period, or a combination thereof based on performing the channel access procedures.

A reinforcement learning (RL) process is used to allocate UL/DL resources and is also used to offload traffic from a first access point (e.g., macro access point) to a second access point (e.g., a micro access point) when the load on the first access point is too high. The RL process is able to handle the dynamic nature of UL/ DL imbalances and is therefore able to maximize usage of resources without compromising quality of service.

A data packet, that is to be transmitted in a dual connectivity (DC) or carrier aggregation (CA) based communications system, may include an indication to indicate whether the data packet is configured to be transmitted in a first frequency of a first carrier or a second frequency of a second carrier, and be transmitted, by a communication device, in the first frequency or the second frequency based on the indication. A data packet in the communications system may also be transmitted first in a first frequency higher than a second frequency, and then be retransmitted in the second frequency upon transmission failure of the data packet in the first frequency.
