[0023] An embodiment of the present application provides a method for processing PRB utilization of a base station. Figure 1 The figure is a flow chart of the communication encryption control method applied to the source device side, including the following steps:

[0033] Specifically, this embodiment is based on the formula: , determine the PRB utilization of the target base station, where, Indicates the PRB utilization rate of the target base station; Represents the signal to interference plus noise ratio of the target base station.
[0034] It should be understood that the PRB utilization rate determined in this embodiment can be used to optimize the network of the target base station. For example, adjusting the uplink and downlink gains of the target base station. It should be noted that in the scenario where the base station is used for signal relay, its uplink and downlink gains need to be reasonably set so as not to cause the base station noise floor to rise. Adjusting the uplink and downlink gains of the base station by PRB utilization is currently an effective means to avoid raising the base station noise floor. That is, in this embodiment, the uplink and downlink gains of the target base station can be adjusted to a target value that matches the PRB utilization rate; wherein, when the uplink and downlink gains of the target base station are adjusted to the target values, the corresponding base station noise floor is less than or equal to the preset base station noise floor allowable value.
[0035] In summary, the method of this embodiment proposes the concept of a reference value and a correction value of PRB utilization, and uses the reference value and the correction value of PRB utilization to achieve accurate calculation of PRB utilization. Among them, the reference value of PRB utilization is mainly estimated by some important parameters of the target base station, such as the total signal power in the downlink time slot bandwidth, the cell bandwidth and the first subcarrier power decision threshold, and the first subcarrier power decision threshold is determined based on the received signal strength and the number of subcarriers of the target base station. The correction value of PRB utilization is used to correct the reference value of PRB utilization, which can be estimated by some measurement parameters and measurement environment parameters of the target base station, such as the full-band subcarrier power and the second subcarrier power decision threshold of the target base station, wherein the second subcarrier power decision threshold is determined based on the first subcarrier power decision threshold, the corresponding measurement equipment thermal noise coefficient when measuring the full-band subcarrier power, and the corresponding environmental thermal noise coefficient when measuring the full-band subcarrier power. Under the interaction of the two estimated reference values and the correction value, a more accurate PRB utilization can be approached, and the PRB utilization finally determined can be used for network optimization of the base station.
[0036] The method of this embodiment is introduced below in combination with actual application scenarios.
[0037] refer to Figure 2 As shown, the process of this application scenario includes the following steps:
[0038] S1: Determine the received signal strength (RSSI) of the target base station based on the co-directional orthogonal signals of the target base station.
[0039] IQ signals are orthogonal signals, where I stands for in-phase and Q stands for quadrature, which is 90° out of phase with I. IQ signals are the mapping of continuous signals in a two-dimensional rectangular coordinate system and are usually used for baseband signal conversion and reconstruction.
[0040] In this step, the IQ signal of the target base station is sampled by the switch. The sampled IQ signal can be filtered by the primary synchronization signal (PSS) to remove the SSB out-of-band signal noise.
[0041] After that, the IQ signal is subjected to time domain correlation processing according to the 3GPP protocol, and a correlation peak (preferably the largest correlation peak) greater than the base station noise floor is selected from the IQ signal after time domain correlation processing, so as to intercept the time domain data of 4 OFDM symbols according to the position of the correlation peak and the frame structure for fast Fourier transform (FFT) to determine the RSSI of the target base station. At the same time, the SSB signal sequence and the Nid(2) signal sequence are intercepted from the selected correlation peak.
[0042] It should be noted that determining RSSI based on FFT belongs to the prior art and will not be described in detail in this article.
[0043] S2: Determine a first subcarrier decision threshold Tsc according to the received signal strength RSSI of the target base station and the number of subcarriers.
[0044] Specifically, taking the target base station including 20RBs as an example, usually, each RB is set with 12 subcarriers, then based on the above, the first subcarrier decision threshold is .
[0045] S3: Generate a signal sequence related to the secondary synchronization signal (SSS) according to the Nid(2) signal sequence of the target base station, correlate the signal sequence with the frequency domain, and extract the Nid(1) signal sequence from the largest correlation peak that is greater than the base station background noise.
[0046] It should be noted that Nid(2) and Nid(1) are standard signals in the 3GPP protocol.
[0047] S4: Calculate the cell ID from the obtained Nid(2) and Nid(1).
[0048] Wherein, the cell ID is represented by the cell CELLID, then CELLID=3*Nid(1)+Nid(2). Cinit is also a standard signal in the 3GPP protocol.
[0049] S5: Determine the Cinit signal sequence of the target base station by using CELLID, and select the signal corresponding to the largest correlation peak from the Cinit signal sequence to determine it as the RS signal sequence.
[0050] It should be noted that the Cinit signal and the RS signal are standard signals in the 3GPP protocol. This step belongs to the prior art and will not be described in detail here.
[0051] S6: Use the RS sequence to perform channel equalization and polar decoding on the signal of the target base station to obtain a Master Information Block (MIB) message.
[0052] The MIB message contains parameter information such as subcarrier offset (kSSB), configuration parameters of the physical downlink control channel (PDCCH) (pdcch-ConfigSIB) and subcarrier spacing (SCS).
[0053] S7: According to the kSSB and pdcch-ConfigSIB in the MIB message, the location of CORESET and Type0-PDCCH CSS information are determined. Based on this information, CORESET0 can be demodulated, and DCI1-0 information can be obtained by blindly detecting PDCCH.
[0054] S8: The DM-RS signal of the PDSCH is demodulated by CORESET0, DCI1-0, MIB message, etc., and the DM-RS signal is LDPC decoded to obtain the SIB1 message, and the cell bandwidth cellBW is determined by the SIB1 message.
[0055] Among them, the SIB1 message includes the cell's bandwidth information, frequency offset information, subcarrier spacing information, etc.
[0056] S9: Based on cell bandwidth cellBW and cell center frequency , measure the total signal power within the downlink timeslot bandwidth of the target base station .
[0057] This step can be performed by the transceiver according to the cell bandwidth cellBW, the cell center frequency The configuration is used to measure the target base station ,Should Measurement is an existing function of the transceiver. In addition, the cell center frequency This is clearly defined in the 3GPP protocol and will not be elaborated here.
[0058] S10: According to , cell bandwidth cellBW, first subcarrier power decision threshold , determine the benchmark value of the PRB utilization rate of the target base station .
[0059] S11: judging the threshold based on the full-band subcarrier power and the second subcarrier power of the target base station , determine the correction value of the PRB utilization of the target base station .
[0060] In this step, the cell center frequency , cell bandwidth cellBW and subcarrier spacing information, measure the power of all subcarriers in the full frequency band, and record the results as [SCRP(1), SCRP(2), *…SCRP(n)];
[0061] In addition, when measuring power, the thermal noise factor NF (dB) of the measuring equipment and the current environmental thermal noise are determined to be No (dBm) = -173.87dBm + 10lgB.
[0062] Afterwards, at the first subcarrier power decision threshold Based on this, the second subcarrier power decision threshold is calculated Based on the above, we can know that: .
[0063] Finally, according to the formula: , determine the correction value of the PRB utilization of the target base station .
[0064] S12: Based on benchmark value and correction value , determine the PRB utilization of the target base station .
[0065] As mentioned earlier, .
