Abstract: A random access method and apparatus are provided. The method includes: a terminal device obtains a position of the terminal device and a position of a network device, the terminal device determines a time adjustment value based on the position of the terminal device and the position of the network device, and the terminal device sends a random access preamble based on the time adjustment value and a random access channel (RACH) resource configured by the network device. Based on this solution, the terminal device may determine the time adjustment value based on the position of the terminal device and the position of the network device, and adjust a time for sending the random access preamble on the RACH resource. This helps avoid a problem that random access preamble receiving time windows overlap, thereby increasing a success rate of accessing the network device by the terminal device.

Abstract: This application provides an uplink signal sending method and a terminal. The terminal may determine a symbol that needs to be punctured, and send the uplink signal based on the symbol that needs to be punctured, so that conflicting use of the overlapping symbol is avoided. Further, the terminal may notify the source cell and/or the target cell of the symbol that needs to be punctured, so that the source cell or the target cell improves, according to a notification indication, decoding on the uplink signal sent by the terminal.

Abstract: Methods, systems, and apparatus for communications are provided. In one aspect, a communication method including: determining, by a first communications apparatus, buffer latency information, and sending, by the first communications apparatus, the buffer latency information. The buffer latency information is determined based on a buffer latency of one or more data packets. The buffer latency indicates one of a time interval between a time point at which a data packet arrives at an access stratum (AS) and a time point at which a corresponding buffer status report (BSR) is sent, or a time interval between a time point at which a data packet arrives at an AS and a time point at which a corresponding uplink grant is received.

Abstract: Embodiments of this application disclose example data transmission methods and example devices. One example method includes receiving, by a first network device, resource configuration assistance information, where the resource configuration assistance information is used to indicate a communication pattern of user equipment. The first network device can then send dedicated resource configuration information to the user equipment based on the resource configuration assistance information, where the dedicated resource configuration information is used by the user equipment in a radio resource control (RRC) non-connected state to access the first network device, and where the RRC non-connected state is an RRC idle state or an RRC inactive state. The first network device can then perform data transmission with the user equipment by using the dedicated resource configuration information.
