    Abstract: A reference time determining method and apparatus are provided, to prevent aberrations in a control instruction execution time caused by inconsistency between a reference time of a terminal and a reference time of a control device in the conventional technology. In this application, the terminal may receive a plurality of pieces of time reference information sent by the network device. When the terminal receives indication information from the network device, the terminal may select, based on the indication information, one piece of time reference information from the plurality of pieces of time reference information as first time reference information. The indication information indicates the first time reference information. After determining the first time reference information, the terminal may determine the reference time of the terminal based on the first time reference information.

    Abstract: This application provides a communication method, a communications apparatus, and a system, to reduce a transmission delay of an emergency service. The method may include receiving an uplink grant. The method may also include determining, based on a time-domain position of an uplink grant resource indicated by the uplink grant, a first uplink grant resource used to transmit first service data. Furthermore, the method may include transmitting the first service data on the first uplink grant resource.

    Abstract: A terminal device flexibly configures a time length of a first timer (a downlink hybrid automatic repeat request (HARQ) round trip time timer or an uplink HARQ round trip time timer) based on different application scenarios. A wireless communication method includes: obtaining feature information of a first air interface format and/or feature information of first transmission data; and determining a time length of a first timer based on the feature information of the first air interface format and/or the feature information of the first transmission data, where the first timer is used to indicate that monitoring a physical downlink control channel (PDCCH) is not required within the time length of the first timer.

    Abstract: A communication method and apparatus is provided, to properly schedule retransmission of an uplink resource in a scenario in which uplink resources overlap in time domain. The method includes: determining, by a terminal, that a priority of a first uplink resource is higher than a priority of a second uplink resource in the first uplink resource and the second uplink resource that have an overlapping part in time domain; and when determining to send a signal by using the first uplink resource on the overlapping part, indicating, by the terminal to a network device, whether a MAC PDU is formed for the second uplink resource or whether data is stored in a corresponding buffer for the second uplink resource.

    Abstract: A data integrity protection method and apparatus in a network environment are described. A terminal device obtains an integrity protection algorithm and a key corresponding to a session or a flow, and a DRB corresponding to the session. The terminal device performs, by using the integrity protection algorithm and the key corresponding to the session, integrity protection on data of the DRB corresponding to the session or the flow, where one session includes a plurality of flows. Different integrity protection algorithms and keys can be used for different sessions, and different integrity protection algorithms and keys can also be used for different flows. In this way, integrity protection is more flexible and meets security requirements of a same user for different services.
