Embodiment Construction

[0062] Embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0063] figure 2 A schematic diagram of a communication system involved in this application is given. The communication system may include at least one network device 100 (only one is shown), and a sending terminal 201 and a receiving terminal 202 that perform uplink / downlink communication with the network device 100 . Sidelink communication is performed between the transmitting terminal 201 and the receiving terminal 202 .

[0064] Wherein, the side link communication may include unicast communication, multicast communication and broadcast communication. This application is applicable to both unicast communication and multicast communication. Wherein, unicast communication means that one sending terminal sends data to one receiving terminal. Multicast communication means that one sending terminal sends data to multiple receiving...

Abstract

A side link communication method and device. The method includes: when the first terminal and the second terminal perform data transmission through the sidelink, when the network equipment receives an error in the sidelink response information sent by the second terminal, and the first terminal and the network equipment When the uplink signal quality between is greater than or equal to the first signal quality threshold, the first terminal receives first information from the network device, and the first information is used to instruct the first terminal to send sidelink response information to the network device ; The first terminal sends sidelink response information to the network device. When the network equipment receives an error in the response information of a terminal on the sidelink, and the uplink signal quality between another terminal on the sidelink and the network equipment is good, the other terminal sends The response information of the side link, so that the terminal that sends the response information of the side link to the network device can be flexibly configured to ensure normal communication of the side link.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a sidelink communication method and device. Background technique [0002] In the new generation of wireless (new radio) vehicle wireless communication technology (vehicle to everything, V2X), the sending and receiving parties adopt the hybrid automatic repeat request (HARQ) technology to ensure the correctness of data transmission. That is, if the receiver successfully receives the data, it will give a correct acknowledgment (acknowledgment, ACK) to the sender, and if the receiver fails to receive the data successfully, it will give a negative acknowledgment (non-acknowledgment, NACK) to the sender. Among them, V2X can also be called sidelink communication. [0003] There are two modes of resource allocation for sidelink communication (sidelink communication), mode 1 and mode 2, wherein, in mode 1, the base station allocates resources for terminal equipmen...
