And if the terminal chip is a high-pass chip, the terminal sends the second terminal capability information to the network equipment. And if the terminal chip is the samsung chip, the terminal sends the third terminal capacity information to the network equipment. For the description of the first terminal capability information, the second terminal capability information, and the third terminal capability information, reference is made to the description in step 202, and details are not repeated here.
204. And the network equipment determines the terminal type of the terminal according to the terminal capability information, wherein the terminal type is divided based on different chip capabilities.
And if the network equipment receives the first terminal capability information, the network equipment determines that the terminal is the terminal type based on the Haesi chip. And if the network equipment receives the second terminal capability information, the network equipment determines that the terminal is the terminal type based on the high-pass chip. And if the network equipment receives the third terminal capability information, the network equipment determines that the terminal is the terminal type based on the samsung chip.
Optionally, 205, the network device performs power differentiated scheduling and multi-user paired differentiated scheduling according to different terminal types.
On one hand, the network device performing power differentiated scheduling according to different terminal types includes: if the terminal is of a terminal type based on the Haesi chip, the network equipment executes power backoff scheduling on the terminal according to the first path loss threshold value; if the terminal is of a high-pass chip-based terminal type, the network equipment executes power back-off scheduling on the terminal according to the second path loss threshold value; if the terminal is of a terminal type based on the three-star chip, the network equipment executes power back-off scheduling on the terminal according to the third path loss threshold value; the first path loss threshold value, the second path loss threshold value and the third path loss threshold value are not equal to each other.
Further, the network device performs power differentiated scheduling according to different terminal types, and specifically may sequentially perform the following steps one to four.
The method comprises the following steps: the network equipment calculates the equivalent path loss, which is marked as PL。
When there is a Power Headroom Report (PHR) update and a physical uplink shared channel reference signal received power (PUSCH RSRP) update, the network device may calculate an equivalent path loss according to a first formula, where the first formula is: pL＝PSDRE-RSRPRE＝PCMAX，f，c-max(PH，0)-10*log10(PUSCH RE NUM)-PUSCH RSRP。
Wherein, PSDREPower Spectral Density (PSD), PSD for each time-frequency resource REREObtained by PUSCH signal measurements. RSRPREReference signal received power, RSRP, for each time-frequency resourceREAlso obtained from PUSCH signal measurements. PCMAX，f，cAnd a field carried in the PHR reported by the terminal represents the maximum power of the carrier wave corresponding to the power margin calculated by the terminal, and the unit is dbm. The PH is a field carried in the PHR reported by the terminal, and indicates the power headroom of the corresponding terminal on the corresponding subcarrier, and the unit is dbm. And the PUSCH RE NUM is the time-frequency resource number scheduled by the PUSCH and is obtained by uplink scheduling. And the PUSCH RSRP is the reference signal received power of the antenna domain which finally participates in calculation.
Step two: the network device estimates the received signal strength according to the equivalent path loss, and records the signal strength as RSSI.
The network device estimates the downlink RSSI according to a second formula, wherein the second formula is: the downlink RSSI ═ Ptotal + PDSCH channel beam gain-PL actual ═ Ptotal-PL + (PDSCH channel beam gain-PUSCH beam gain) ≈ Ptotal-PL.
Wherein, Ptotal: the channel number can be calculated by reference power ReferencePwr, number TotalRBNum of user scheduling RBs and number TxNum of cell channels. Ptotal ═ ReferencePwr +10log10 (totaalbnum × 12) +10log10 (TxNum). PL true: representing the true path loss.
Step three: and the network equipment performs power back-off scheduling on the terminals of different terminal types through different path loss threshold values.
Based on the Haesi chip type terminal, the first path loss threshold value is configured by a first parameter, and the power backoff validation judgment takes effect according to the configuration of the first parameter; based on the high-pass chip type terminal, the second path loss threshold value is configured by a second parameter, and the power back-off effective judgment takes effect according to the configuration of the second parameter; and based on the terminal of the three-star chip type, the third path loss threshold value is configured by a third parameter, and the power back-off validation judgment takes effect according to the configuration of the third parameter.
Due to the difference of the processing capacities of the terminal chips, the processing capacities for receiving downlink signals are different, and if the same threshold configuration is used for effective power backoff, each type of terminal cannot achieve the optimal processing gain. Therefore, after different terminal types are identified, different effective power backoff schedules are configured for different terminals, so that the same power backoff scheduling process can be achieved, and each type of terminal can obtain the maximum gain.
Step four: the network device performs a power back-off validation decision and calculates a power back-off amount.
The power back-off means that the base station side reduces the power (i.e. power back-off) of the PDSCH channel of the base station and improves the performance of the terminal under the condition that the terminal has poor performance under high power. Due to the differences in downlink processing capabilities of different terminals, power backoff needs to be performed under different path loss thresholds.
On the other hand, under the condition of satisfying isolation and correlation discrimination, the network device performs multi-user pairing differentiated scheduling according to different terminal types, including: if the number of terminals of the same terminal type in a cell is less than the preset maximum pairing layer number, the network equipment performs multi-user pairing on the terminals of different terminal types; if the number of terminals of the same terminal type in the cell is greater than or equal to the preset maximum pairing layer number, the network equipment preferentially performs multi-user pairing on the terminals of the same terminal type, and performs frequency division scheduling on the terminals of other terminal types. In brief, the isolation refers to the distance between spatial positions of users, the correlation refers to the correlation of user channel information, the correlation is high, the correlation is considered to be high, the pairing performance is poor, the correlation is low, the correlation is considered to be low, the pairing performance is good, and other relevant descriptions about the isolation and the correlation decision in multi-user pairing can refer to other relevant data, which are not described in detail in this application.
The multi-user pairing means that a plurality of users perform services simultaneously in the same cell, and in order to maximize multiplexing of the same time-frequency resource, the cell throughput and the experience of each user are improved. Zero forcing operation can be carried out on PDSCH weighting when multiple users are paired and simultaneously carry out service, so that the weights of all users are orthogonal to each other to reduce interference, and all paired users can use the same time-frequency resource; when multiple users do not match, the same time-frequency resource is equally divided in the time domain or the frequency domain, and the optimal effect of improving the cell throughput cannot be achieved. In the embodiment of the application, multi-user pairing differentiated scheduling is performed based on different terminal types, so that the average throughput of a cell and the experience of each user cannot achieve the optimal effect.
It should be noted that, in the embodiment of the present application, the conditions for determining the isolation and the correlation, and the scheduling process and configuration related to the multi-user pairing may refer to other related data, which is not described in detail herein. Optionally, the method for determining the terminal type in the embodiment of the present application may further include: the network equipment requests an Identity Request through the IMEI of a coded plaintext, and the Identity Type is 2 information and is issued to the terminal, and the terminal reports the IMEI. The network equipment judges whether the received Identity Response is received or not and decodes and acquires the IMEI. And the network equipment further confirms the type of the terminal through the IMEI.
In the embodiment of the application, the network equipment queries and acquires the chip capability of the chip in the terminal through the capability query request, and the network equipment determines the terminal type of the terminal based on the terminal capability information, wherein the terminal type is divided based on different chip capabilities. Therefore, according to the technical scheme in the first aspect, the network device can not only acquire the support degree of the terminal capability to solve the technical defect that the support degree of the terminal capability cannot be achieved, but also determine the terminal type based on the terminal capability information, wherein the terminal type is divided based on different chip capabilities to accurately identify the terminal designed based on different chips. Further, the network device executes power differentiated scheduling and multi-user pairing differentiated scheduling based on different terminal types, so that the network performance of the terminal can be effectively improved, and the user experience is improved.
