Abstract: This application discloses a node and a communication method, to resolve a problem of relatively high implementation complexity and costs of an RN. The communication method includes: sending, by a first node at a first protocol layer, a first message to a peer first protocol layer on an interface between the first node and a second node; and receiving, by the second node at the first protocol layer, the first message from the peer first protocol layer on the interface between the second node and the first node. This application relates to the field of communications technologies.

Abstract: A measurement method includes sending, by a first device to a second device, a message including a first configuration, wherein the first configuration indicates that a first event triggers the second device to send a first measurement message. The first event includes at least a channel quality of a measurement object is less than a first threshold, the channel quality of the measurement object is lower than a channel quality of a serving cell of the second device, the channel quality of the measurement object is less than the first threshold, and the channel quality of the serving cell of the second device is greater than a second threshold, or the channel quality of the measurement object is lower than the channel quality of the serving cell of the second device and the channel quality of the serving cell of the second device is greater than the second threshold.

Abstract: A data processing method and a terminal device and a base station. The method includes: the terminal device determines to change the type of at least one wireless carrier of the terminal device from a first type to a second type and discards a radio link control protocol RLC and/or an RLC service data unit buffered by a transmit side of an RLC entity of at least one radio bearer. The terminal device assembles an RLC protocol data unit received by a receive side of the RLC layer entity of at least one radio bearer into an RLC service data unit, and delivers the RLC service data unit to an upper layer entity of the RLC layer entity, where the upper layer entity is an upper layer entity of the RLC layer entity before the type of the at least on radio bearer is changed.

Abstract: A control signaling processing method, a device, and a system relate to the field of communications technologies, to perform integrity protection on control signaling exchanged between a DU and UE in a CU-DU separated access network architecture. The method includes: determining, by a DU, integrity protection parameters and an integrity protection algorithm, where the integrity protection parameters and the integrity protection algorithm are used to perform integrity protection on a signaling radio bearer between the DU and UE; determining, by the DU, a message authentication code MAC-I based on the integrity protection parameters and the integrity protection algorithm; and receiving, by the DU, control signaling sent by an RRC layer of the DU, and sending, to the UE, the control signaling carrying the MAC-I.
