Abstract: A communication method includes that, when a terminal device receives indication information used by a network device to indicate the terminal device to work on a non-dormant bandwidth part (BWP) in a secondary cell, the terminal device can determine a specific BWP on which the terminal device is to work, and perform a corresponding operation. A network device generates indication information, and sends the indication information to a terminal device, where the indication information is used to indicate the terminal device to work on a non-dormant BWP in a first secondary cell. Then, the terminal device enables, according to the indication information, the terminal device to work on a first BWP, where the first BWP is the non-dormant BWP in the first secondary cell.

Abstract: The present disclosure relates to a QoS guarantee method. In one example method, a control plane gateway obtains a QoS parameter. The QoS parameter comprises an allocation/retention priority (ARP) and a QoS class identifier (QCI). The control plane gateway maps the QoS parameter to QoS guarantee information. The QoS guarantee information comprises a differentiated services code point (DSCP) parameter. The control plane gateway sends the QoS guarantee information to a user plane gateway. The QoS guarantee information is to be used by the user plane gateway for QoS marking.
