Abstract: This application relates to a communication method and device. A terminal device sends first data to an access network device on a first resource, and starts a first timer, where the first resource is a preconfigured resource, the first data is small data, and the terminal device is in an RRC non-connected state. If first information is received before the first timer expires, the first timer is stopped, where the first information is information indicating that the first data is successfully transmitted, and the first information is MAC layer information, or the first information is information for scheduling a resource. If the first information is, for example, the MAC layer information, feedback information at a physical layer does not need to be introduced.

Abstract: Described is a network device (203) configured to operate as a first node in a communications network (200) for a user device (201) initiating a small data transmission communication session through a target node (202) in the communications network (200), the network device (203) being configured to, upon receiving a request from the target node (202), send a message to the target node (202), the message comprising an indication of small data transmission configuration information (401, 506) for the user device (201). A corresponding network device (202) configured to operate as a target node is also described.

Abstract: This application relates to a communication method and system. A first network element receives information about downlink data from a second network element, where the downlink data is from a core network device. The first network element is a first DU, and the second network element is a first CU; or the first network element is a first CU-CP, and the second network element is a first CU-UP. If the downlink data meets a downlink small data transmission condition, the first network element sends a paging message that indicates a terminal device to initiate a downlink small data transmission procedure. For example, the first network element is a DU, and the downlink data from the core network device may reach a CU.

Abstract: A user device is configured to transmit and receive signals to and from a network device over a first range of frequencies and implement one or more diverse radio techniques across at least part of the first range, and configured to: receive a request to indicate whether any frequency ranges in the first range are affected by interference between signals of the techniques; and send an indication of one or more frequency ranges in the first range affected by interference between signals of one or more of the diverse radio techniques, the one or more frequency ranges being sub-sets of the first range having a frequency range less than a range of a carrier frequency.
