Abstract: The disclosed techniques enable communication nodes to perform rate adjustments. As an example, a communication node may receive a control information from a network node. Based on the received control information, the control node may determine that the network node supports codec adaptation or that the communication node is allowed to enable the codec adaptation.

Abstract: Provided is a data packet transmission method and device. The method includes: generating, by a first network element, first indication information according to a delivery status fed back by a second network element to the first network element, where the first indication information is used for instructing the second network element which has not successfully sent a data packet to a terminal to discard the data packet indicated by the first indication information. The present disclosure may solve the problem in the related art of unsynchronized data transmission in sending of a data packet to a terminal by a plurality of second network elements.

Abstract: A method for carrying out data integrity protection on a communication network. According to an implementation, a wireless communication device indicates, to a wireless network, the maximum data rate up to which integrity protection is supported for user plane data. A network node (e.g., a node of the core network, such as an SMF) receives this information and determines whether or not to enable integrity protection for user plane data based on the information (possibly in conjunction with other information such as the minimum data rate to be supported, etc.). The network node then communicates the decision to enable or disable integrity protection to a RAN node (e.g., a wireless base station).
