Disclosed is a method of managing PDU session inter-working in a User Equipment, UE, wherein if the UE changes from WB-N1 mode to NB-S1 mode, then the UE sets the state of any dedicated EPS bearer context to be inactive.

Methods and apparatuses are provided for activating or deactivating packet duplication in a wireless communication system. A central unit (CU) of a first base station transmits, to a distributed unit (DU) of the first base station, via an F1 interface, information to activate or deactivate a dual connectivity (DC) based packet duplication for a data radio bearer (DRB). The information is transmitted to a second base station. A medium access control (MAC) control element (CE) indicating whether to activate or deactivate packet duplication for the DRB, based on the information, is transmitted to a user equipment (UE).

A data scheduling method includes: transmitting to a terminal a determination rule for determining target location information corresponding to each of a plurality of target time domain units, the plurality of target time domain units being a plurality of time domain units for performing data bearing according to scheduling signaling. As such, in the dynamic scheduling of a terminal by a base station, an objective of simultaneously scheduling a plurality of target time domain units through one scheduling signaling to perform data bearing can be realized.

A method by which a first device (100) performs sidelink transmission is provided. The method can comprise the steps of: determining a priority of a first carrier including a plurality of BWPs; allocating transmission power for the first carrier on the basis of the priority; and performing sidelink transmission through the plurality of BWPs on the basis of the transmission power.

A communication method and apparatus, and relate to the communication field. A network side may control establishment of a connection, between a terminal device and a UPF network element, allowed to be shared by a plurality of traffic flows, thereby reducing a connection establishment process. The method includes: an SMF network element receives, from a terminal device, a first message used to request to establish or update a PDU session; and the SMF network element sends a second message to the terminal device, where the second message is used to indicate that the PDU session is successfully established or updated, the second message includes a multi-flow connection parameter, and the multi-flow connection parameter is used to indicate that a plurality of traffic flows in the PDU session are transmitted by using a same connection.

A method and apparatus for selecting a destination based on hybrid automatic repeat request (HARQ) feedback in a wireless communication system is provided. A first wireless device selects a destination, from multiple destinations, having a first logical channel with a highest priority among multiple logical channels having data available for transmission. The HARQ feedback is disabled for the first logical channel. The first wireless device selects one or more second logical channels not configured with the HARQ feedback among the multiple logical channels.

Provided are a transmission control method and device. The method includes that: a Control Plane (CP) network element receives a data transmission feedback message and/or a bearer management message sent by a User Plane (UP) network element, where the bearer management message is determined by the UP network element according to data transmission quality between the UP network element and a Distributed Unit (DU), and the data transmission feedback message is configured to indicate data transmission states of the UP network element and the DU; and a bearer of the UP network element is managed according to the data transmission feedback message and/or the bearer management message.
