Abstract: This disclosure provides a capability reporting method, a capability report processing method, a device, an apparatus and a medium. The capability reporting method includes: reporting, by a terminal, proactively or in response to a request of a positioning server, a positioning signal processing capability for a period of discontinuous reception to a base station serving the terminal and/or to the positioning server. After allocating resources to the terminal according to the positioning signal processing capability for the period of discontinuous reception, the base station configures and sends to the terminal an indication indicating whether processing of a positioning reference signal is allowed during the period of discontinuous reception. A positioning server selects a positioning method for the terminal according to positioning service quality of service requirements and the positioning signal processing capability for the period of discontinuous reception.
