Abstract: An entity establishment processing method and an apparatus are provided. The processing method includes: A terminal side device receives first indication information from a first network side device, where the first indication information is used to trigger reestablishment of a first PDCP entity of the terminal side device. When a first bearer corresponding to the first PDCP entity is not a radio bearer used to perform duplication transmission between the terminal side device and a core network side device, in a process in which the terminal side device reestablishes the first PDCP entity based on the first indication information, the terminal side device sets a parameter of the first PDCP entity to an initial value.

Abstract: Embodiments of the present disclosure provide a method and an apparatus for semi-persistent scheduling (SPS). The method for semi-persistent scheduling includes: interacting, by a first user equipment, with a base station to obtain an SPS resource allocated by the base station; performing, by the first user equipment, device-to-device (D2D) communication with second user equipment by using the SPS resource; and after the D2D communication ends, sending, by the first user equipment, release indication information to the base station, so that the base station releases the SPS resource. In embodiments of the present disclosure, after D2D communication ends, the first user equipment sends a release indication message to a base station, so that the base station can release an SPS resource, preventing waste of resources.
