In one implementation, performance testing of multi-link aggregation is performed on a wireless device under test, that is, link aggregation is used between a target wireless simulator and a device under test at a MAC (Medium Access Control ) layer, so that links are mapped to multiple channels and frequency bands, and performance such as throughput, time delay and the like under the condition of competition of multiple wireless simulators is tested. For example, according to the simulation scenario, a target multipath simulator, an interference multipath simulator, a competing multipath simulator, a target wireless simulator, an interference wireless simulator, and a competing wireless simulator are preset; further, after the competition wireless simulator receives the instruction of the control device, a competition signal is sent to the wireless device to be tested, the competition signal is lost in the transmission process, and the signal loss effect is realized through the competition multipath simulator; the attenuated competition signals are transmitted to the tested wireless equipment in the full-wave darkroom through the antenna probe array; similarly, after receiving an instruction of the control device, the interference multipath simulator sends a signal to the wireless device to be tested, the signal is lost in the transmission process, and the loss effect of the signal is realized through the interference multipath simulator; the attenuated signals are transmitted to the tested wireless equipment in the full-wave darkroom through the antenna probe array; in the process that the interference multipath simulator and the competition multipath simulator send signals to the tested wireless device, the target multipath simulator completes the target signal transmission process with the tested wireless device. And finally, the control equipment determines parameters such as time delay and throughput according to the target signal sent by the target wireless simulator and the received signal of the corresponding target signal received by the wireless equipment to be tested, and determines the performance of the wireless equipment to be tested according to the parameters such as time delay and throughput.

The first circulator and the second circulator are added in the link, so that the uplink and the downlink can be separated, and meanwhile, the independent control of the uplink channel and the downlink channel can be realized, so that the channel control of the link is more accurate.

For example, if only the transmission of the signal from the interfering wireless simulator to the wireless device under test is implemented, the transmission of the signal from the wireless device under test to the interfering wireless simulator is prohibited, then the setting is reduced when the signal is transmitted from the interfering wireless simulator to the wireless device under test; if the signal is transmitted from the tested wireless equipment to the interference wireless simulator, the receiving direction interference multipath simulator in the interference link is set to increase attenuation, so that the interference multipath simulator has an isolation effect of 10dB to 90 dB.

It should be noted that, in the embodiment of the present application, the performance of the wireless device to be tested is determined mainly according to the signal transmission situation between the target wireless simulator and the wireless device to be tested, so that only the interference link and the competing link are considered to affect the tested link. Optionally, in order to ensure the accuracy of the transmission condition of the tested link and prevent the target signal in the full-wave darkroom from affecting the interference link and the competition link, the interference multipath simulators for the downlink and the downlink can be respectively set, so that the transmission link and the receiving link are isolated.

Finally, by setting the data of the interference wireless simulator in the interference link, the wireless signals under different RU (Resource Unit) resources are used as interference signals, and the throughput and time delay performance of the tested wireless device under the MRU self-adaptive punching mechanism are accurately determined.

In another implementation, performance testing of the multi-AP cooperative mechanism is performed on the wireless device under test, and only the target link and the interfering link may be used. Specifically, an interference multipath simulator in an interference link is configured, so that no isolation effect exists when signals are transmitted from any direction; and configuring the interfering wireless simulator and the interfering multipath simulator in the interfering link (the interfering wireless simulator and the target wireless simulator are in a coexistence relationship because the signals are not isolated in the interfering link). For example, the configured target multipath simulator applies 10dB of additional link attenuation and the configured interfering multipath simulators each apply 20dB of additional attenuation; further, the control device configures the output power of the target wireless simulator to be 20dbm,802.11be,36 channels, 160MHz bandwidth and 2×2 MIMO connection by configuring the signal analysis parameters of the target wireless simulator and the signal analysis parameters of the interference wireless simulator (two) respectively, and the streaming parameters are set to be TCP and 10 streaming parallel streaming 120s; two interference wireless simulators (AP and STA respectively) are configured, wherein the output power of the two interference wireless simulators is 20dBm, the output power of the two interference wireless simulators are 802.11be and the output power of the two interference wireless simulators are 44 channels, the bandwidth of 160MHz is 160MHz, the connection is 2X 2 MIMO, the streaming parameters are set to TCP, 2 parallel streaming is carried out for 120s, and the single streaming speed is limited to 300Mbps. Firstly, respectively performing streaming test on a tested link and an interference link, and respectively recording the throughput and the time delay of the tested link in the uplink and the downlink as well as the throughput and the time delay of the interference link in the uplink and the downlink.

For example, the throughput and delay of the measured link in the uplink and the throughput and delay of the interfering link in the uplink; throughput and time delay of the tested link in uplink and throughput and time delay of the interference link in downlink; throughput and time delay of the tested link in the downlink and throughput and time delay of the interference link in the uplink; the throughput and time delay of the tested link in the downlink and the throughput and time delay of the interference link in the downlink.
