Description

Measurement method, device, node and storage medium Technical Field The present application relates to the field of communications technologies, and in particular, to a measurement method, a device, a node, and a storage medium. Background The unlicensed spectrum belongs to the shared spectrum, the node needs to obtain the channel access right in a competitive mode to use the spectrum, and when the number of the nodes is large, the node may not preempt the channel, so that uncertainty exists in transmitting data on the unlicensed spectrum, or the node may delay preempting the channel, and delay in data transmission is caused. In addition, in the unlicensed spectrum, there is a problem that the hidden nodes are hidden nodes, as shown in fig. 1, the nodes 1 and 2 are interfered by the node 4, but the node 3 with a longer distance is not interfered by the node 4, and the node 3 cannot sense the existence of the node 4, so that the node 4 is the hidden node of the node 1 and the node 2. In order to guarantee the requirement of some services on time delay, the existence of interference needs to be found in time, and the interference condition of a channel is usually measured in the following two ways, one is to measure the intensity of the interference. The signal is measured at each measurement time to obtain the received signal strength, then the received signal strength at all measurement times in a certain period of time (determined by the reporting period) is averaged to obtain the average received channel strength (such as the received signal strength indication), and the other is to measure the frequency of interference and the strength of interference. The received signal strength is measured at each measurement time, and when the received signal strength at some measurement time during the period is higher than a certain threshold value, the measurement time accounts for a percentage of all measurement times (such as channel occupancy), wherein the measurement time can be configured as a periodic time (such as orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol, and subframe). However, both the two methods measure the interference magnitude and frequency from probability, if the configured reporting period is longer, when some times of stronger interference exist in the measurement time, the signals with stronger interference will be averaged due to more counted measurement times, so that the interference cannot be seen from the measurement result, if the configured reporting period is shorter, the measurement report is reported more frequently, and both the measurement results are sent to the node through the radio resource control (Radio Resource Control, RRC) message of the measurement report, and the node cannot find the existence of the interference in time.
