Abstract: A mobility management method, a terminal, and a network-side device are provided. The mobility management method in embodiments of this application includes: obtaining, by a terminal, target configuration information, where the target configuration information includes duration information of a plurality of candidate cells; and performing, by the terminal, at least one of a cell selection procedure or a connection reestablishment procedure based on the target configuration information.

Abstract: A method for starting neighbor cell measurement, a terminal, and a network side device are provided. The method for starting neighbor cell measurement includes: obtaining, by a terminal, target configuration information, where the target configuration information includes time information used to indicate the terminal to start neighbor cell measurement; and starting neighbor cell measurement based on the target configuration information.

Abstract: A cell reselection method includes obtaining target information of a first cell, where the target information is configured for indicating access information of the first cell; and determining, based on the target information and terminal capability information, the first cell as a candidate cell or a barred cell when cell reselection is performed.

Abstract: This application discloses a time information sending method, a terminal, and a network-side device, and pertains to the communication field. The method includes: in a case that a first condition is satisfied, sending first time information to a network side, where the first time information is used for obtaining a timing advance value of the terminal.

Abstract: Embodiments of this application disclose a resource allocation method and apparatus and a terminal, where the method includes: obtaining a first uplink grant for new transmission by a terminal; and performing resource allocation for a resource designated by the first uplink grant, according to at least one of the following: HARQ uplink retransmission indication, configuration of enabling or disabling of HARQ uplink retransmission for a HARQ process, configuration of enabling or disabling of HARQ uplink retransmission for a logical channel, and association between logical channels and HARQ processes.
