Embodiment Construction

[0135] In the description of the present application, unless otherwise specified, " / " means "or", for example, A / B may mean A or B. The "and / or" in this article is just an association relationship describing associated objects, which means that there can be three relationships, for example, A and / or B, which can mean: A exists alone, A and B exist at the same time, and B exists alone These three situations. In addition, "at least one" means one or more, and "plurality" means two or more. Words such as "first" and "second" do not limit the number and order of execution, and words such as "first" and "second" do not necessarily limit the difference.

[0136] It should be noted that, in this application, words such as "exemplary" or "for example" are used as examples, illustrations or illustrations. Any embodiment or design described herein as "exemplary" or "for example" is not to be construed as preferred or advantageous over other embodiments or designs. Rather, the use of ...

Abstract

The present application provides a communication method and device. In this method, a first terminal receives a data packet and determines whether it is the destination terminal of the data packet. If so, the access between the source terminal and the destination terminal of the data packet is not established. In the case of a layer connection and / or a logical channel, the first terminal establishes an access layer connection and / or a logical channel with the source terminal, thereby solving the problem of establishing an access layer connection and / or a logical channel in a multi-hop terminal scenario problem, to ensure the correct transmission of data packets in multi-hop terminal scenarios.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] In the long term evolution (LTE), the design goal of the vehicle to everything (V2X) is to meet the broadcast business with low quality of service (QoS), while the new radio (NR) Medium V2X needs to meet high-QoS services such as vehicles platooning, extended sensors, advanced driving, and remote driving. These high-QoS services have end-to-end latency (E2E latency) ) is less than or equal to 3 milliseconds (ms), reliability (reliability) reaches 99.999%, data rate (data rate) reaches 1000 megabits (ie 1Gbps), communication distance is less than or equal to 1 kilometer (km) and other high QoS requirements. [0003] At present, in LTE V2X, the maximum transmission distance between two terminals is 300 meters (m), which is far from meeting the service requirements of NRV2X. In order to improve th...
