Embodiment 1

[0039] The timing method provided in this embodiment is applicable to various communication systems, including but not limited to the 4th Generation Mobile Communication (referred to as: 4G) system, NR (New Radio) system (or 5G system) , a new generation of wireless communication systems after the 5G system, etc.

[0040] The 5G system or the new generation of wireless communication systems after the 5G system will use carrier frequencies higher than those used by the 4G system for communication, such as 28GHz, 45GHz, 70GHz, etc. The frequency has a shorter wavelength, so it can ensure that more antenna elements can be accommodated per unit area, and more antenna elements mean that the beamforming method can be used to improve the antenna gain, thereby ensuring the coverage performance of high-frequency communication. At the same time, for the challenge of coverage, wireless backhaul transmission can also solve this problem. However, there is self-receiving interference betwe...

Embodiment 2

[0074] This embodiment also provides a timing device, which can be set on a device specially used for timing setting in the communication system, or on a communication node device on a communication path, see Figure 4 As shown, the timing device includes:

[0075] The processing module 42 is configured to determine the time adjustment amount of the current link based on the signal transmission time PT at the sending and receiving ends of the current link, and the time adjustment amount of the previous hop link of the current link on the communication path.

[0076] The setting module 43 is configured to set the signal transmission time of the current link according to the time adjustment amount of the current link.

[0077] In this embodiment, each link on the communication path can pass Figure 4 The timing device shown completes the setting of the signal transmission time, so as to ensure that the data sent by the terminals on each communication path arrive at the base sta...

Embodiment 3

[0096] This embodiment also provides a communication node device, which may be a base station or various relay point devices, etc., see Figure 5 As shown, the communication node device includes a processor 51, a memory 52 and a communication bus 53;

[0097] The communication bus 53 is used to realize connection and communication between the processor 51 and the memory 52;

[0098] The processor 51 is used to execute one or more programs stored in the memory, so as to realize the steps of the timing method shown in the above-mentioned embodiments.

[0099] This embodiment also provides a computer-readable storage medium, which can be applied to various communication devices. The computer-readable storage medium stores one or more programs, and the one or more programs are processed by one or more implemented by the controller, so as to realize the steps of the timing method shown in the above-mentioned embodiments.

[0100] In order to facilitate the understanding of the pr...

Abstract

Embodiments of the invention provide a timing method and device, a communication node device and a computer storage medium, which are suitable for a communication path comprising at least two communication node devices; various links on a communication path of at least one relay node device are introduced, the time adjustment amount of each link on the communication path can be determined based onsignal propagation time (PT) of a transmitting end and a receiving end of each link and the time adjustment amount of the previous-hop link of each link, so that the signal emission time of each linkis set according to the time adjustment amount of each link, and thus the data can reach the upper-layer node simultaneously, and finally, the data sent by terminals on various communication paths reach a base station side simultaneously.

Description

technical field [0001] The present invention relates to the communication field, in particular to a timing method, device, communication node equipment and computer storage medium. Background technique [0002] In a wireless communication system, since the distance between each terminal and the base station is different, it is necessary to ensure that the data transmitted by each terminal reaches the base station side at the same time. In order to achieve the above purpose, the current timing mechanism is as follows: the base station informs the terminal how much time to advance the transmission needs to be made through TAC (TimingAdvance Command, time advance command), and the terminal performs corresponding timing after receiving the TAC, so as to transmit in advance at the corresponding time point , but this situation is only for the case where the terminal is directly connected to the base station. At this time, there are only the base station and the terminal on the com...
