Embodiment Construction

[0037] In the V2X of LTE, the semi-static resource selection method of long-term perception is mainly used to obtain transmission resources. In NR V2X, due to the increase of business types, the existing long-term sensing method cannot well meet the business needs. Therefore, a semi-static resource selection method combining short-term sensing and long-term sensing is proposed to determine The side link is used to send control information and data time-frequency resources.

[0038] However, after the time-frequency resource is determined by combining short-term sensing and long-term sensing, how to set the time-domain transmission position of side link control information and data on the determined time-frequency resource has not yet been resolved.

[0039]In view of the above problems, an embodiment of the present invention provides a side link transmission method, by using the preset position of the time-frequency resource used for transmission on the side link as the time d...

Abstract

The invention discloses a side link transmission method, a terminal and a computer readable storage medium. The method comprises the following steps: acquiring a time-frequency resource for transmission on a side link; and taking a preset position on the time-frequency resource as a time domain sending position of side link control information, and sending the side link control information on theside link. By applying the scheme, the receiving terminal can determine the specific sending position of the side link control information on the time-frequency resource, the blind detection complexity of the receiving terminal can be reduced, the receiving efficiency can be improved, and the power consumption of the receiving terminal can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a side link transmission method, a terminal and a computer-readable storage medium. Background technique [0002] V2X (Vehicle to X), that is, information exchange between vehicles and the outside world, is a key technology for future intelligent transportation systems. The application of V2X technology enables communication between vehicles, vehicles and pedestrians, and vehicles and base stations, and a series of traffic information such as real-time road conditions, road information, and pedestrian information can be obtained, effectively improving driving safety, reducing congestion, and improving traffic efficiency . [0003] In the long term evolution (Long Term Evolution, LTE), a user terminal (User Equipment, UE) applying the V2X technology only supports periodic services with the same data packet size. Compared with the V2X of LTE, the V2X of the new rad...
