Abstract: The present disclosure provides an uplink data packet transmission method. The method includes: determining, by a terminal device, a CP length of a first uplink data frame; if the terminal device is in a state of out of uplink synchronization with a base station and in an RRC connected state, or is in an RRC idle state, generating the first uplink data frame for an uplink data packet according to the CP length and sending the first uplink data frame to the base station. The CP length is greater than a CP length of an uplink data frame sent by a terminal device that is in a state of uplink synchronization and in an RRC connected state. Therefore, signaling procedures such as random access and uplink synchronization can be omitted, so that the terminal device can directly send the uplink data packet by performing signaling exchange once.

Abstract: According to a method and an apparatus in embodiments, in a redirection scenario, a target network device receives, from a terminal device, a first measurement result obtained in a source cell, and configures carrier aggregation CA and/or dual connectivity DC for the terminal device based on the first measurement result. In this way, a network side obtains a measurement result in advance, which reduces a latency between configuring, by a network side device, a measurement configuration for a terminal device after redirection and receiving a measurement result from the terminal device, so that the network side can configure proper CA and/or MR-DC for the terminal device earlier.

Abstract: Embodiments of this application provide a communication method and a communication apparatus. In the method, a terminal device obtains a first RA report that includes information about a random access procedure initiated by the terminal device to a source secondary access network device. After the master access network device of the terminal device changes from a source master access network device to a target access network device, the terminal device sends a first message to the target access network device. The first message includes the first RA report and first identification information, and the first identification information indicates the source master access network device.

Abstract: A method is provided, including: configuring a conditional candidate primary secondary cell group cell PSCell addition or change for a terminal device; and performing, by a master network device, early data transmission oriented to a network device to which a candidate PSCell belongs, and for example, before the terminal device accesses the candidate PSCell, sending a data packet to the network device to which the candidate PSCell belongs, where a form of the data packet is a packet data convergence protocol protocol data unit, and the data packet includes a data packet on an MN terminated secondary cell group bearer and/or a data packet on an MN terminated split bearer. In this way, after the terminal device accesses a candidate network device, the candidate network device may send forwarded data to the terminal device, to reduce a data transmission delay.

Abstract: This application provides a method and an apparatus for configuring minimization of drive-tests MDT. The method for configuring MDT includes: A terminal device receives first MDT measurement configuration information and first indication information from a first network device. The terminal device learns, based on the first indication information, whether a type of first MDT configured by the first network device for the terminal device is signaling based MDT or management based MDT. Further, after establishing a connection to a second network device, the terminal device sends second indication information to the second network device, and reports the type of the first MDT that has been configured for the terminal device. The management based MDT overwrites signaling based MDT previously configured by the first network device for the terminal device can be avoided, thereby increasing a possibility that the management based MDT does not overwrite the configured signaling based MDT.

Abstract: This application provides a communication method and apparatus, and a system, to protect security and user privacy in a data transmission process. After determining to establish a radio resource control (RRC) connection in anonymous mode, a terminal device sends a request to an access network device, to request to establish the RRC connection in anonymous mode, so that the access network device establishes the RRC connection in anonymous mode to the terminal device. The solutions in this application may be applied to a communications system, for example, may be applied to a 5th generation 5G network.

Abstract: The present disclosure relates to delay measurement methods and apparatus. In one example method, a first communications device receives a data unit from a second communications device, where the data unit includes time information, the time information is used to indicate a first moment at which the second communications device sends the data unit, and the time information indicates the first moment based on a part of bits of a frame number. The first communications device determines a delay from the second communications device to the first communications device based on the first moment and a second moment, where the second moment is a moment at which the first communications device receives the data unit.
