the whole mobile communication framework is composed of three layers, as the radio frequency index is not related to the RRC layer, the interface between the MAC layer and the RRC layer and the interface between the MAC layer and the PHY layer are called to form a non-signaling test sequence, the action of the radio frequency signal of each time point can be determined by removing signaling interaction of the formed non-signaling test sequence, a meter can be used for scanning the signal of each time point, and downlink signals of different forms can be injected; the integrity of the MAC and the PHY is ensured, and the consistency of the radio frequency index test can be ensured.

The structure is implemented according to a layered logic, and the specific layers are determined depending on the software and hardware implementation architecture of the whole communication protocol stack and the point to be observed, wherein the implementation can be considered to be performed in three layers.
The first level is: configuring related parameters of a PHY layer process/MAC layer process defined by a protocol specification to form a non-signaling test sequence for checking the correctness of the PHY/MAC process implementation defined by the protocol specification and specific radio frequency performance indexes shown by the process execution. For example, configure the data sources for ALL0/ALL1/PN 9; configuring different coding modes and filter coefficients; configuring RB, debugging mode, subframe ratio, antenna and the like, and configuring the sequence parameters into a PHY layer/an MAC layer, so that the test result of the to-be-tested index related to the hardware running the code is more accurate when the to-be-tested index is tested.
The second level is: configuring relevant parameters of a logic channel/a transmission channel to form a non-signaling test sequence; the method is used for checking the realization correctness of the channel and the specific radio frequency performance index shown by the fact that the channel related parameter finally falls on the radio frequency signal; for example, a PUSCH channel is knocked down, only the PUCCH channel is reserved, and the signal index of the PUCCH channel is observed; independently observing indexes of the PCFICH channel; specific UCI parameters are configured for the PUSCH or the PUCCH, radio frequency signal indexes are observed, and the like, so that the accuracy of indexes to be measured for the PUCCH is guaranteed;

The three layers have emphasis, the non-signaling test sequence of the first layer/the second layer is biased to be heavier than the whole complete PHY layer/MAC layer downward behavior specified by the investigation protocol specification; the non-signaling test sequence of the third layer is more focused on the inspection of different scenarios of the hardware.

Therefore, the test of the indexes to be tested is completed, and the control equipment obtains the test result of each index to be tested.
In order to meet the testing requirements of each index to be tested, the signal testing method provided by the embodiment of the invention uses the control equipment to issue the sequence parameters of each index to be tested, so that the signal testing device can respectively generate an uplink signal corresponding to the form parameters and a downlink testing sequence corresponding to the testing parameters according to the form parameters and the testing parameters in the sequence parameters, thus, in the signal testing device and the testing equipment, an uplink signal and an uplink testing sequence which are matched with each other exist respectively, and the downlink testing sequence and the downlink signal which are matched with each other exist respectively, so that only when the uplink signal issued by the signal testing device is matched with the uplink testing sequence in the testing equipment, the signal testing device and the testing equipment can test each index to be tested, therefore, when the signal testing device issues the uplink signal to the testing equipment, the signal testing device and the testing equipment are enabled to realize sequence synchronization, and the downlink testing sequence and the uplink testing sequence are respectively executed, so that the signal testing device can test the downlink signal according to the downlink testing sequence matched with the downlink signal, and can also synchronously trigger the testing equipment to test the uplink signal according to the uplink testing sequence matched with the uplink signal, so that the testing result of each index to be tested is obtained, and thus, the testing requirement of each index to be tested is met, the testing blind spot existing in the testing of the radio frequency index of the mobile terminal is eliminated, and the testing requirement is further met.
