Description

Millimeter wave communication system and related test method

Technical Field

The present application relates to the field of communications technologies, and in particular, to millimeter wave communication systems and related testing methods.

Background

Electromagnetic waves in the frequency domain of 30-300GHz (wavelength of 1-10 mm) are generally called millimeter waves, and the millimeter waves are located in the overlapping wavelength range of microwave and far-infrared waves, so that the millimeter waves have two spectrum characteristics. In which, compared with light waves, the attenuation of millimeter waves when they are propagated using an atmospheric window (frequency at which some attenuation due to resonance absorption of gas molecules is minimal when millimeter waves and submillimeter waves are propagated in the atmosphere) is small, and the influence of natural light and thermal radiation sources is small.

Millimeter waves have numerous applications in the fields of communications, radar, remote sensing, and radio astronomy. In order to improve the communication reliability of the millimeter wave system, the millimeter wave relay station is introduced into the millimeter wave system, but how to better play the role of the millimeter wave relay station is still the subject of long-term research in the industry.

Referring to fig. 2, fig. 2 is a schematic flowchart of a testing method of a millimeter wave communication system provided by way of example in the embodiment of the present application.

201. A first millimeter wave base station in the millimeter wave communication system monitors satisfaction of a first condition.

The millimeter wave communication system may include: the system comprises a first millimeter wave relay station cluster, a second millimeter wave relay station cluster, a third millimeter wave relay station cluster, a first millimeter wave base station and a second millimeter wave base station; the third millimeter wave relay station cluster comprises at least 2 millimeter wave relay stations; the first millimeter wave base station is a main service base station of the first millimeter wave relay station cluster, and the second millimeter wave base station is a main service base station of the second millimeter wave relay station cluster; the first millimeter wave base station is a main service base station of the third millimeter wave relay station cluster, and the second millimeter wave base station is an auxiliary service base station of the third millimeter wave relay station cluster.

It may be understood that, in this embodiment, description is given by taking the first millimeter wave base station as a main serving base station of the third millimeter wave relay station cluster and the second millimeter wave base station as an auxiliary serving base station of the third millimeter wave relay station cluster as an example, of course, another scenario may also be that the second millimeter wave base station is the main serving base station of the third millimeter wave relay station cluster and the first millimeter wave base station is the auxiliary serving base station of the third millimeter wave relay station cluster, and the implementation manner of this scenario may be similar to that in the above.

202. When monitoring that a first condition is met, a first millimeter wave base station sends a cooperation test request to a second millimeter wave base station, wherein the cooperation test request carries a cooperation test time interval identifier, and the cooperation test time interval identifier is used for representing a first test time interval. The cooperative test request is used for instructing the second millimeter wave base station to send a first test sequence to the third millimeter wave relay station cluster in the first test time period.

203. And the first millimeter wave base station sends a first test sequence to the third millimeter wave relay station cluster in the first test period.

Specifically, the first millimeter wave base station may send the first test sequence to some or all of the millimeter wave relay stations in the third millimeter wave relay station cluster in the first test period.

204. The first millimeter wave base station receives a first set of response sequences (comprising one or more response sequences) corresponding to the first test sequence from the third cluster of millimeter wave relay stations.

Specifically, the first millimeter wave base station may respectively receive response sequences corresponding to the first test sequences from some or all of the millimeter wave relay stations in the third millimeter wave relay station cluster, and respectively receive corresponding response sequences from corresponding millimeter wave relay stations, thereby forming a first response sequence set.

205. And the first millimeter wave base station evaluates the link communication quality level Lq1 between the first millimeter wave base station and the third millimeter wave relay station cluster based on the first response sequence set.

206. And after receiving the cooperative test request from the first millimeter wave base station, the second millimeter wave base station sends a second test sequence to the third millimeter wave relay station cluster in the first test period.

Specifically, the second millimeter wave base station may send the second test sequence to part or all of the millimeter wave relay stations in the third millimeter wave relay station cluster in the first test period.

207. The second millimeter wave base station receives a second set of response sequences (comprising one or more response sequences) corresponding to the second test sequence from the third cluster of millimeter wave relay stations.

Specifically, the second millimeter wave base station may respectively receive response sequences corresponding to the second test sequences from some or all of the millimeter wave relay stations in the third millimeter wave relay station cluster, and the received corresponding response sequences from each millimeter wave relay station form a second response sequence set.

210. And under the condition that the link communication quality level Lq1 meets a second condition, the first millimeter wave base station sends an identity switching instruction for indicating switching of identities of main and auxiliary base stations to a third millimeter wave relay station cluster, wherein the identity switching instruction is used for switching the first millimeter wave base station from the auxiliary service base station of the third millimeter wave relay station cluster to the main service base station of the third millimeter wave relay station cluster, and switching the second millimeter wave base station from the main service base station of the third millimeter wave relay station cluster to the auxiliary service base station of the third millimeter wave relay station cluster.

Referring to fig. 3, fig. 3 is a schematic flowchart of another testing method for a millimeter wave communication system provided by way of example in the embodiment of the present application.

301. A first millimeter wave base station in the millimeter wave communication system monitors satisfaction of a first condition.

302. When monitoring that a first condition is met, a first millimeter wave base station sends a cooperation test request to a second millimeter wave base station, wherein the cooperation test request carries a cooperation test time interval identifier, and the cooperation test time interval identifier is used for representing a first test time interval. The cooperative test request is used for instructing the second millimeter wave base station to send a first test sequence to the third millimeter wave relay station cluster in the first test time period.

303. The first millimeter wave base station sends a first test sequence to the millimeter wave relay station rp1 in the third millimeter wave relay station cluster in the first test period.

A link exists between the millimeter wave relay station rp1 and the first millimeter wave base station, and the link is in an active state. It is to be understood that, before the first test sequence is transmitted, the first millimeter wave base station may activate the link between it and the millimeter wave relay station rp1. It can be understood that the link between the first millimeter wave base station and each millimeter wave relay station in the third millimeter wave relay station cluster is in a deactivated state before the first millimeter wave base station activates the link between the first millimeter wave base station and the millimeter wave relay station rp1.

For example, links exist between other millimeter wave relay stations in the third millimeter wave relay station cluster except the millimeter wave relay station rp1 and the first millimeter wave base station, but these links are in a deactivated state, that is, the millimeter wave relay station rp1 is the only millimeter wave relay station in the third millimeter wave relay station cluster, which has an activated state link with the first millimeter wave base station.
