The present application discloses a method for multiplexing multi-service UCI on an uplink data channel to solve the problem of different numbers of coded bits of UCI of different services. The method includes: regulating a value of a code rate offset of UCI relative to a UL-SCH, and calculating the number of modulation symbols for transmitting coded information according to the code rate offset. With the consideration that URLLC data requires higher reliability when UCI of the eMBB service is multiplexed on a UL-SCH of the URLLC service, a corresponding numerical value is required to be smaller than 1. When UCI of a URLLC is multiplexed on a PUSCH of the eMBB, the code rate offset is increased. furthermore, high-layer signaling may include a scaling parameter. It is suitable to apply the method disclosed by the present application to different service multiplexing scenarios simultaneously.

Methods and system for a centralized unit and a distributed unit of a base station to operatively cooperate with each other are disclosed. In one embodiment, a method performed by a first communication node includes: in response to receiving a request, transmitting a first message to a second wireless communication node requesting to either establish or modify a context of a data radio bearer (DRB); and receiving a second message from the second wireless communication node indicating that the context of the DRB has been established or modified at the second wireless communication node, wherein the first message comprises first user plane address information of the DRB, and the second message comprises second user plane address information of the DRB.

Embodiments of a multi-link device (MLD) are generally described herein. The MLD may be configured for multi-link communication on a plurality of links. The MLD may be configured with a plurality of stations (STAs). Each STA may be a logical entity that includes a singly addressable instance of a medium access control (MAC) layer and a physical (PHY) layer of a link of the plurality of links. The MLD may configure traffic identifier (TID) assignment for the MLD for multi-link communication with another MLD. The multi-link communication may be configurable to support one or more data streams, wherein each of the data streams corresponds to a TID. The MLD may determine an assignment of the TIDs to the STAs of the MLD.

A base station central unit receives, from a base station distributed unit, assistance information indicating whether subsequent data is expected for a small data transmission (SDT) procedure of a wireless device. The base station central unit transmits a radio resource control (RRC) release message to the wireless device based on the assistance information.

A data transmission method and apparatus, and a communication device are provided. The data transmission method is performed by a first communication device, including: generating a desired guard symbol medium access control layer control element (MAC CE) when a preset trigger condition is met; and sending the desired guard symbol MAC CE to a second communication device.

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a UE. The UE receives a first trigger. The UE determines, based on the first trigger, whether it is possible that a first transmission and reception point (TRP) and a second TRP are to transmit a first down link control channel and a second down link control channel to the UE concurrently on a carrier. The UE monitors the first down link control channel and the second down link control channel in a particular slot when it is possible that the first TRP and the second TRP are to transmit the first down link control channel and the second down link control channel to the UE concurrently on the carrier.
