[0005] In the existing mechanism, on the one hand, the terminal device obtains the PPPP threshold value on the sidelink, and then combines the PPPP value with the highest priority in the media access control layer protocol data unit of the sidelink of the terminal device with a Threshold value comparison, if the priority corresponding to the PPPP value with the highest priority is higher than the priority corresponding to the threshold value, the sidelink MAC layer protocol data unit is transmitted preferentially, if the PPPP value corresponds to If the priority is lower than the priority corresponding to the threshold, the uplink media access control layer protocol data unit will be transmitted preferentially. This method only considers the comparison between the transmission requirements of the side link and the threshold to determine the UL and SL transmission priority order, the existing problems include: when the priority corresponding to the threshold value obtained by the terminal device is too low, the data transmission requirements on the SL link will be sacrificed; when the threshold value obtained by the terminal device corresponds to When the priority is too high, the data on the SL will be sent frequently, thus sacrificing the data transmission requirements on the UL link

Embodiment Construction
[0113] The technical solution in this application will be described below with reference to the accompanying drawings.
[0114] In addition, it should be understood that in the description of this application, terms such as "first" or "second" are only used for the purpose of distinguishing descriptions, and cannot be understood as indicating or implying relative importance, nor can they be understood as Indicate or imply an order. The "first information", "second information" and other information in this application have different numbers. The numbers are only used for contextual convenience, and the different sequence numbers themselves have no specific technical meaning. For example, the first parameter value, The second parameter value and the like can be understood as one or any one of a series of related parameter values. The function or function of the numbered information, for example, can be determined by the context content of the numbered information and / or by the...

The present application provides a communication method and related equipment related to data transmission in the Internet of Vehicles. The method includes: the terminal device acquires a first parameter value having a mapping relationship with the priority of the uplink logical channel and a second parameter value of the sidelink, and the terminal device obtains the first parameter value and the second parameter value based on the first parameter value and the second parameter value The comparison of the values determines whether to transmit the data to be transmitted on the uplink or to transmit the data to be transmitted on the sidelink. By implementing the method, the vehicle-mounted terminal equipment in the Internet of Vehicles can better take into account the transmission requirements of the uplink and the sidelink.
Description
technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and related equipment related to data transmission priority in the Internet of Vehicles. Background technique [0002] The Internet of Vehicles V2X (vehicle to X) is the key technology of the intelligent transportation system.
