[0004] However, during the two-way transmission process, the UE may move. During the UE's moving process, the path loss of the direct link may be greater than the path loss of the serving cell where the UE is located. At this time, according to the above calculation method, the The path loss of the serving cell where the UE is located is used as the transmission power of the UE, which will cause the current two-way direct link to be unable to maintain, resulting in the sudden loss of connection between the two UEs performing V2X transmission, which is very detrimental to user experience

The present disclosure relates to a maintenance and maintenance triggering method and device for a data transmission link. The maintenance method includes: establishing a direct link for V2X service data transmission, and performing communication between a first user equipment and a second user equipment according to the direct link ; Obtain the first path loss; obtain the second path loss; when the relationship between the first path loss and the second path loss reaches the trigger condition, maintain the V2X transmission link; the trigger method includes: establishing a direct link; The first path loss; acquiring the second path loss; triggering the maintenance of the V2X transmission link when the relationship between the first path loss and the second path loss meets the trigger condition. By maintaining the V2X transmission link when the relationship between the first path loss and the second path loss reaches the trigger condition, the maintenance and maintenance trigger method and device for the data transmission link according to the embodiments of the present disclosure can improve communication performance , to improve user experience.
Description
technical field [0001] The present disclosure relates to the field of wireless communication, and in particular to a maintenance and maintenance triggering method and device for a data transmission link. Background technique [0002] In Long Term Evolution (LTE, Long Term Evolution), if the user equipment (UE, User Equipment) performing V2X (Vehicle to Everything) transmission uses the transmission resources configured by the serving cell to perform V2X transmission, power control needs to be performed, and power control cannot be performed according to The maximum transmission power that the UE can transmit, but the impact on the serving cell needs to be considered. Therefore, the V2X transmission power is the maximum transmission power of the UE on the current frequency, and the transmission power required by the UE according to the path loss calculation of the serving cell. The smaller value in between. [0003] Because feedback is not considered in LTE V2X, only one-way...
