Abstract: A communication method includes deriving a first key. The first key is determined based on a second key by using a first parameter value. The second key is a master key. The first parameter value is a 1st parameter value in a first set. The first set includes a plurality of parameter values associated with a secondary node to which a first cell belongs. The parameter value is a secondary node counter value. The communication method also includes deriving a third key based on the first key. The third key is one or more of a user plane key or a control plane key. The third key is used to perform encryption or data integrity protection on one or more of data or signaling between a terminal device and the first cell.

Abstract: A communication method and a communication apparatus are provided. The method includes: receiving, by a terminal device, measurement configuration information from a network device, where the measurement configuration information indicates at least one measurement area, and each measurement area is associated with at least one to-be-measured target; and measuring, by the terminal device in an idle state or a third state, the to-be-measured target based on a camped cell and the measurement configuration information. The terminal device measures, in the idle state or the third state, the to-be-measured target that needs to be measured, to avoid a resource waste caused by measuring all to-be-measured targets.

Abstract: A measurement reporting entry processing method and a device are provided. The method includes receiving indication information from a network device, where the indication information indicates a processing manner of a measurement reporting entry; and processing the measurement reporting entry based on the indication information.

Abstract: The present invention concerns a method for optimizing ROHC RTP (Robust Header Compression Real Time Protocol) compression applied to IP header of data packets stream so as to use more compact formats enable to remain in a steady state, to never discard received packet, and to serve radio resources without requiring to modify ROHC specification. In the method, when handover or mobility procedure is started, new reference values are normally added to a sliding compression window, but no reference value is removed from the window as long as the handover or mobility procedure is on going. After the handover or mobility procedure is complete, when the number of values transmitted on the new radio link are appropriate to cope against the error properties on the new link, all older values can be removed at once from the compression window, thereby reverting to normal window operation.

Abstract: An embodiment method for measurement gap scheduling includes generating, by a serving cell to which a UE is connected, a bitmap that indicates timing of measurement gaps for reference signals transmitted by the serving cell and at least one neighbor cell of the serving cell in beamformed and beam swept beams, and transmitting the bitmap to the UE in a configuration message.
