Embodiment Construction

[0079] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0080] The present invention aims at the problem that in the existing V2X system, when the UE at the sending end broadcasts service information through the side link subframe, various receiving terminals with different moving speeds cannot correctly receive the service information, and provides a method that satisfies different speeds as much as possible. The transmission reliability requirements of the receiving terminal, the sending method, receiving method and terminal of business information that improve the packet arrival rate of the system.

[0081] like Figure 1-Figure 5 As shown, the structures of several optional pilot patterns are as follows:

[0082] like figure 1 As shown, the pilot pattern used for low-speed mobile or low-frequency offset...

Abstract

The present invention provides a service information sending method, receiving method and terminal, wherein the sending method includes: determining the pilot pattern used when transmitting service information N times from M different pilot patterns; according to the N times When transmitting service information, encode the service information using the pilot pattern used each time the service information is transmitted, obtain the encoded service information, and send the encoded service information N times to the receiving terminal; Wherein, both M and N are integers greater than or equal to 2, and the receiving terminal is a terminal that directly communicates with the sending terminal that sends service information. The solution of the present invention ensures as much as possible that the service information sent by the sending terminal sending the signal in the V2X direct communication can be correctly received by as many receiving terminals with different moving speeds as possible, so as to improve the packet arrival rate of the system.

Description

technical field [0001] The present invention relates to the technical field of Internet of Vehicles transmission, in particular to a method for sending service information, a method for receiving it, and a terminal. Background technique [0002] In the Long Term Evolution (LTE, Long Term Evolution) system, the side link is defined to support direct communication and direct discovery between terminal equipment (User Equipment, UE), where the side link physical channel includes: physical side chain Physical Sidelink Shared CHannel (PSSCH), Physical Sidelink Control Channel (PSCCH), Physical Sidelink Discovery CHannel (PSDCH) and Physical Sidelink Broadcast Channel (Physical Sidelink Broadcast CHannel, PSBCH). [0003] In the direct communication service of the Internet of Vehicles (V2X) in the high-speed mobile scene, the UE sending the signal sends the signal in the form of broadcast, and multiple UEs at the receiving end can simultaneously receive the signal sent by the UE ...
