The present application provides a method and a device in nodes used for wireless communications. A first node receives first configuration information, the first configuration information being non-unicast, and the first configuration information indicating K sub-bearers; herein, K is a positive integer greater than 1; for any higher-layer packet transmitted respectively through the K sub-bearers, sequence numbers of the higher-layer packet in the K sub-bearers are the same; a first sub-bearer is one of the K sub-bearers, and a higher-layer packet transmitted in any of the K sub-bearers is transmitted through the first sub-bearer. The present application enables the users to acquire by broadcast configuration information of sub-bearers transmitting the same MBMS on different nodes or CGs, so that the same MBMS can be acquired from multiple nodes simultaneously with decreased traffic interruptions caused by inter-node mobility.

An apparatus for performing a vehicle OTA update is provided. The apparatus includes a load factor measurement device that measures a load factor of a first communication channel for transmitting data for an OTA update of a controller included in a vehicle; a communication speed adjustment device that generates information for adjusting a transmission speed of the data over the first communication channel, based on the measured load factor; and a communication channel change device that generates information about whether to change a communication channel for the OTA update of the controller, based on the generated information for adjusting the transmission speed.

A method for link aggregation of a plurality of communication links, performed in a communication arrangement, the method comprising; obtaining a data segment to be transmitted, identifying a preferred communication link out of the plurality of communication links for transmission of the data segment, and, if the preferred communication link is not available for transmission of the data segment within a current time period, identifying an alternative communication link out of the plurality of communication links different from the preferred communication link, fragmenting the data segment into at least a first fragment and a second fragment, attaching a fragment header to each of the first and second fragments, each fragment header being configured to identify the respective fragment as a fragment belonging to a data segment, and transmitting the first fragment over the alternative communication link.

A multi-band communication method, including: before sending data frames in a plurality of frequency bands, respectively determining request to send (RTS) frames that are in a preset format and correspond to each frequency band; and sending the RTS frames corresponding to each frequency band to a station.

A next generation NodeB (gNB) implements a radio access network (RAN) convergence functionality for new radio (NR) and wireless local area network (WLAN) access, the gNB further implementing a split architecture comprising a central unit (CU) and a distributed unit (DU) for each of the NR access and WLAN access. The gNB receives a data packet for transmission to a user equipment (UE) implementing the RAN convergence functionality, the data packet comprising one of a control plane (CP) packet or a user plane (UP) packet. The gNB splits the data packet via a convergence layer residing on the NR CU or a convergence layer residing on the WLAN CU and transmits the split data packet over the NR access and the WLAN access.

A wireless communication network serves user communication devices using Internet Protocol (IP) and Integrated Access and Backhaul (IAB). An IAB Mobile Termination (MT) and an IAB donor establish a wireless IAB link. The IAB MT and a Centralized Unit (CU) establish IP links over the wireless IAB link. The IP links have different QoS levels. The IAB MT exchanges data streams with the user communication devices. The data streams have different QoS requirements. The IAB MT and the CU correlate the QoS requirements of the data streams with the QoS levels of the IP links. The IAB MT and the CU exchange individual ones of the data streams over individual ones of the IP links based on the QoS correlations. The CU exchanges the data streams with a data communication network based on the QoS requirements.

An ultra-reliable and low latency communications local breakout (URLLC-LBO) method and a URLLC-LBO method for a next generation radio access network (NG-RAN) are provided. The method includes: configuring a core network to establish a packet data unit (PDU) session between first user equipment (UE) and the core network; configuring the first UE to establish a URLLC service; configuring a near real-time RAN intelligent controller (near-RT RIC) to establish an F1-LBO routing process to set an LBO dedicated radio bearer (DRB) for the local URLLC service; configuring an F1-LBO virtual network function (VNF) module according to a traffic rule by the F1-LBO routing process, to establish a routing table through the F1-LBO VNF module, in which the routing table defines a relationship between a first location and a second location of the LBO DRB.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may detect a trigger for transmitting a buffer status report (BSR). The UE may transmit, to a base station, a long BSR for a single logical channel group (LCG) with data to be transmitted based at least in part on at least one of a determination that a current buffer size for the single LCG is greater than a maximum buffer size indication in a short BSR or a determination that a current achievable uplink throughput using the short BSR is less than a configured uplink throughput. Numerous other aspects are described.

A data flow transmission method, a terminal, and a network-side device are provided. The data flow transmission method includes: mapping QoS flows of an MBS to an MRB and a DRB; transmitting the QoS flows through at least one of the MRB or the DRB.
