Abstract: This application may be applied to an internet of vehicles, for example, V2X and LTE-V. A first terminal apparatus determines, a first resource pool. The first terminal apparatus detects control information of a second terminal apparatus, where the control information indicates second service data of the second terminal apparatus, and the control information includes location information of the second terminal apparatus, a first frequency domain resource, and a periodicity of the second service data. The first terminal apparatus determines an unavailable time-frequency resource in the first resource pool based on location information of the first terminal apparatus, the location information of the second terminal apparatus, a first threshold, the first frequency domain resource, and the periodicity of the second service data. The first terminal apparatus selects a first time-frequency resource from available time-frequency resources in the first resource pool to transmit first service data.

Abstract: A beam training method and a related device are disclosed. The method includes: sending, by a first communications device, sidelink control information (SCI) to a second communications device, where the SCI is used to instruct the first communications device to send at least one channel state information-reference signal (CSI-RS) to the second communications device; and sending, by the first communications device, the at least one CSI-RS to the second communications device based on the SCI, where the at least one CSI-RS is used by the second communications device to determine that a beam corresponding to a CSI-RS with highest signal strength in the at least one CSI-RS is a beam for communication between the second communications device and the first communications device. The CSI-RS used for beam training is dynamically sent based on the instruction of the SCI.

Abstract: N time-frequency resources are determined by a first communications device. Any two of the N time-frequency resources are nonconsecutive in at least one of a time domain and a frequency domain; each of the N time-frequency resources is smaller than a time-frequency resource required for transmitting to-be-transmitted data, a sum of the N time-frequency resources is greater than or equal to the time-frequency resource required for transmitting the to-be-transmitted data and N is a positive integer greater than or equal to 2. First indication information is sent on M of the N time-frequency resources. The first indication information is used to indicate that the N time-frequency resources are used to send the to-be-transmitted data, M is a positive integer less than or equal to N. The to-be-transmitted data are sent on the N time-frequency resources so that time-frequency resource utilization is improved.

Abstract: A random access method, user equipment (UE), a base station, and a random access system, are provided to address relatively long service delay. In various embodiments, after downlink synchronization with a cell is obtained, UE can determine a preamble sequence of the UE in the cell, where the UE has not obtained uplink synchronization with the cell. The UE can then obtain service data and generate a scrambling code, and scramble the service data based on the scrambling code to obtain scrambled service data. The UE can then configure, based on a predetermined resource mapping relationship, time-frequency resources respectively occupied by the preamble sequence and the scrambled service data. The UE then sends on the configured time-frequency resources, the preamble sequence and the scrambled service data to a base station the cell belongs to and receives random access response sent by the base station based on the preamble sequence.
