Problems solved by technology

Although there is only one piece of coordination information for triggering based on predefined conditions, since the coordinating terminal does not know when the sending terminal needs data transmission and the required resource size, it needs to periodically send coordination information, or need to send more auxiliary information to help send terminal resource selection

Embodiment Construction

[0023] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] refer to figure 1 , figure 1 It is a flow chart of a coordination communication method in the embodiment of the present invention. The coordinated communication method may include steps S11 to S14:

[0025] Step S11: when the data packet arrives, send a request message and start a timer;

[0026] Step S12: Send the request message to the corresponding coordinating terminal, one or more coordinating terminals;

[0027] Step S13: receiving the response message sent by each coordinating terminal;

[0028] Step S14: before the timer expires, perform resource selection according to the received response message;

[0029] Step S15: transmit the data packet on the selected resource.

[0030] In the specific implementation of step S11, the request information may be used to request the coordinating terminal to perform inter-UE coordinatio...

Abstract

The invention belongs to the technical field of 5G Internet of Vehicles, and discloses a coordinated communication method, which comprises the following steps: when a data packet arrives, sending a request message, and starting a timer; respectively sending the request messages to corresponding coordination terminals, wherein the number of the coordination terminals is one or more; receiving a response message sent by each coordination terminal; before the timer is overtime, selecting resources according to the received response message; and transmitting the data packet on the selected resources. By applying the scheme, coordinated communication between UEs can be realized in a side link communication scene, and time delay and resources collision probability are reduced.

Description

technical field [0001] The invention belongs to the technical field of 5G Internet of Vehicles, and specifically relates to a coordinated communication method, a user terminal, and a computer-readable storage medium. Background technique [0002] In the sidelink (SL) communication based on 5G new air interface (New Radio, NR), the user equipment (UserEquipment, UE) has two resource allocation modes, one is resource scheduling by the base station, called resource allocation mode 1. The other is resource allocation mode 2 where the UE performs autonomous resource selection. Among them, resource allocation mode 2 does not depend on base station scheduling, so it can operate when there is no cell coverage. In the case of resource allocation mode 2, in order to realize autonomous resource selection, the UE needs to continuously perform resource sensing, obtain the reserved resource information of other UEs, form a candidate resource set according to the result of resource sensin...
