Abstract: A data transmission method, a device, and a system are disclosed and relate to the communications field, to resolve a problem that modulation and coding cannot be performed on data because no corresponding transport block size TBS exists when a quantity of physical resource blocks PRBs of a wireless communications system is greater than 110. A specific solution is: obtaining, by a first device, grouping information, where the grouping information is used to indicate information of grouping N PRBs into M PRB groups; performing modulation and coding by using a TBS that corresponds to each of the M PRB groups, to generate modulation symbols; and transmitting data to a second device by using a physical resource that corresponds to the N PRBs. The foregoing solution is used for data transmission in a wireless network.

Abstract: A data transmission method and a device are disclosed and relate to the field of communications technologies, so that a channel resource preemption probability of a device can be effectively increased by reducing a CCA interval at which a CCA is performed on a channel resource. The method includes: determining, by a first device, a CCA start moment at which a clear channel assessment CCA is performed; determining, by the first device, a CCA interval, where the CCA interval is a time interval between two adjacent CCAs, and a time interval between any two adjacent CCAs is less than a preconfigured data frame period; performing, by the first device, a CCA process according to the CCA start moment and the CCA interval; and sending, by the first device, data at an end moment of the CCA process. The method and the device are used for data transmission.

Abstract: This application relates to the field of communications technologies, and discloses a slot format indication method, a device, and a system. The method includes: generating, by a network device, first indication information, and sending the first indication information to a terminal device; and after receiving the first indication information, determining, by the terminal device, slot formats of M CCs based on the first indication information. The first indication information indicates K slot formats. The K slot formats are the slot formats of the M CCs configured for the terminal device. At least one slot format in the K slot formats is corresponding to at least two CCs in the M CCs. Configuration parameters of the at least two CCs have at least one type of same parameter. The configuration parameter includes at least one of the following parameters: a subcarrier spacing, a cyclic prefix, a bandwidth, or a frequency band.

Abstract: A resource indication method and a related device, where the method includes the obtaining system resource information of a second system, and sending indication information using a resource of a first system, where the indication information indicates the system resource information such that a device receiving the indication information determines the system resource information based on the indication information. Hence, an indication message indicating a system resource of the second system is sent using the resource of the first system. Therefore, a user equipment directly determine the system resource information of the second system based on the indication information, and efficiency of accessing the second system by the user equipment is improved.
