摘要： A method and an apparatus for session reestablishment, an Access and Mobility Management Function entity AMF, a Session Management Function entity SMF and a terminal are provided. The method includes: AMF obtaining a Non-Access Stratum NAS message transmitted by a terminal, where the NAS message is to request to establish a new packet data unit PDU session connected to a same data network as an initial PDU session, and the NAS message carries first identification information of the initial PDU session and second identification information of the new PDU session assigned by the terminal; and transmitting a session management request to SMF corresponding to the first identification information. The session management request carries the first identification information and the second identification information, and the session management request is to cause the SMF to establish the new PDU session based on the first identification information and the second identification information.

摘要： The embodiments of the present disclosure provide a method and a device for constraining a codebook subset. The method includes steps of: determining codebook subset constraint parameters for all or parts of matrix sets for constructing a codebook respectively, each codebook subset constraint parameter indicating an available matrix in a corresponding matrix set; and transmitting the determined codebook subset constraint parameters to a UE. The number of the matrices in each matrix set for constructing the codebook is far less than the number of precoding matrices in the codebook.
