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: 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: 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.

Abstract: Embodiments of this application provide a random access processing method. A random access preamble and uplink data are sent in an initiation phase of a random access procedure, and the random access procedure is ended in time after feedback information for the uplink data is received. According to technical solutions provided in the embodiments of this application, a terminal side device may send the uplink data when sending the random access preamble in the random access procedure. In addition, the random access procedure can be ended in advance after the feedback information for the uplink data is received.

Abstract: A multimedia broadcast multicast communication method, an apparatus, and a system are provided. The method includes: receiving, by a base station, first indication information at a first time, where the first indication information is used to indicate that transmitting service data in a multimedia broadcast multicast service MBSFN manner is to be suspended; and sending, by the base station, second indication information to user equipment UE according to the first indication information, so that the UE suspends, at a second time according to the second indication information, receiving the service data in the MBSFN manner. The first time is earlier than the second time, and duration between the first time and the second time is less than a multicast control channel MCCH modification period. The user equipment is notified in a more timely manner to suspend transmitting the service data in the MBSFN manner.
