LTE (Long Term Evolution ) is a long term evolution of the 3GPP (3 rd GenerationPartnership Project, third generation partnership project) dominant universal mobile telecommunications system technology, which is currently a widely accepted wireless communication technology.
Since the transmission channel of wireless communication is a multipath fading and time-varying channel, CSI (ChannelState Information ) may change continuously. In order to obtain the maximum system capacity of the LTE system in the wireless channel environment, the base station needs to select a proper modulation and coding scheme and subband resources according to the wireless channel environment of each terminal. The terminal needs to detect CSI of the wireless channel in real time and feed back the CSI to the base station. And the base station dynamically adjusts the optimal time-frequency resource allocated to the user according to the fed back CSI.
In an LTE system, CSI includes: CQI (Channel Quality Indicator, channel quality Indication), RI (Rank Indication), PMI (Precoding Matrix Indication, precoding matrix index), and the like. The CQI is a group of indexes, each index corresponds to a modulation mode and code rate, the PMI is a precoding matrix index, and the RI is the rank of a current channel transmission matrix.
The CQI is obtained by mapping according to SINR (Signal to Interferenceplus Noise Ratio, signal-to-interference-and-noise ratio) obtained by the terminal measurement through a mapping table, however, under a fading channel, due to complexity of a wireless channel, the generally obtained SINR has a larger error, so that the base station cannot maximally utilize transmission capability of the wireless channel, and therefore, loss of throughput of the system is caused.

The RI information may also indicate the correlation between multiple transmission channels between the transmitting end and the receiving end, if RI is 1, it indicates that the multiple transmission channels are completely correlated, and the transmitted signals are likely to interfere with each other, so that the receiving end is difficult to accurately receive, if RI is greater than 1, it indicates that there are multiple independent uncorrelated channels, and the UE may receive signals on different channels.
PDSCH: physical Downlink Shared Channel, a physical downlink shared channel, which is used to carry data sent by the base station to the terminal.
RB: resource Block, 12 subcarriers in frequency and one slot in time domain are called 1 RB.
RE: resource Element, one subcarrier in frequency and one symbol in time domain, is called one RE. symbol is the smallest range in the time domain, one symbol is 0.5/0.7ms.
MCS: modulation and Coding Scheme, the base station can perform MCS scheduling according to CSI information reported by the terminal.
Referring to fig. 1, fig. 1 is a flowchart of an information reporting method according to an embodiment of the present application, where the method includes the following steps:
step S110: and acquiring the current downlink channel state information which is currently measured.
The current downlink channel state information comprises combined information formed by a current RI and a current SINR, and the current SINR is determined according to a first SINR obtained by measuring a reference signal sent by the network equipment and a second SINR obtained by measuring a PDSCH.
The network device in the present application may refer to a device capable of communicating with a terminal, and has a wireless transceiver function, including but not limited to: for convenience of description, the following embodiments will take a base station as an example. The terminal also has wireless receiving and transmitting functions, and can be a mobile phone, a tablet, a computer with wireless functions and other devices.
In order to facilitate the base station to implement better MCS scheduling for the terminal, the base station needs to acquire channel state information, and the base station may configure the resources of channel measurement for the terminal in advance, for example, including CSI. In order to better adapt to the change of a wireless channel, the terminal can report downlink channel quality information to the base station through the CSI, wherein the downlink channel quality information is downlink channel state information, and comprises CQI, PMI and RI, so that the base station can select more reliable MCS and better time-frequency resources for the terminal.
In order to facilitate the measurement by the terminal, the terminal may acquire CSI information by measuring a received downlink Reference Signal, such as CRS (Cell Reference Signal, cell-specific Reference Signal) or CSI-RS (Channel State Information-Reference Signal), and report the CSI information to the base station. After the base station configures the terminal, the terminal receives the configuration information, calculates the time-frequency resource where the reference signal is located and related configurations, and after the configurations are determined, the terminal can correctly receive the reference signal and carry out subsequent measurement.
The CQI information obtained by the terminal is obtained through a mapping table of SINR and CQI obtained by pre-simulation, but because the real environment is changeable and often cannot be matched with the simulation channel, the CQI obtained by using the mapping table of SINR and CQI obtained by simulation in the real environment cannot fully represent the real situation of the channel, which causes the BLER (Block Error Rate) to deviate from the ideal BLER when the base station performs scheduling. Therefore, in order to compensate the CQI information, in the embodiment of the present application, the PDSCH needs to be measured to obtain the second SINR, and then the current SINR is determined together according to the first SINR and the second SINR.
In some embodiments, the current SINR may be a sum of the first SINR and the second SINR, or may be a weighted sum of the first SINR and the second SINR, for example, the current sinr=a is equal to the first sinr+b is equal to the second SINR, where the values of a and b may be flexibly set according to the actual requirement, and a+b=1, so that the second SINR is used to compensate the first SINR, and the obtained current SINR is the final SINR, which may make up the difference between the simulated channel and the actual channel, so that the CQI output at last is more accurate.
In addition, when the terminal performs RI measurement, the terminal can perform measurement by adopting a related measurement method, such as SVD decomposition method, max-CP of maximum channel capacity method, max-MMSE-PostCP of maximum post-processing channel capacity method, max-MI of maximum mutual information method and the like. The RI measurement is performed by using the SVD decomposition method, and the process is as follows: the terminal carries out singular value decomposition on the autocorrelation matrix of each subcarrier channel matrix, the obtained singular values are arranged from large to small, the singular values are compared with the signal to noise ratio according to a convention method to obtain the optimal RI value of each subcarrier, the RI values corresponding to L subcarriers are finally selected according to a majority principle, and the current RI value can be obtained by measurement according to the method.
Step S120: and acquiring historical downlink channel state information.
The historical downlink channel state information comprises N pieces of combined information formed by historical RI and historical SINR, and N is an integer greater than or equal to 1.
It will be appreciated that each combination of the historical downlink channel state information is obtained by the terminal during each measurement in the historical period, where the manner of obtaining the historical RI and the historical SINR is identical to the manner of obtaining the current RI and the current SINR described above, and will not be described herein. The terminal may store the RI and SINR measured each time in a storage medium in the form of combined information. Thus, when the historical downlink channel state information is acquired, the corresponding information can be directly read from the storage medium.
Step S130: and calculating the size of a transmission block corresponding to each piece of combination information according to the N+1 pieces of combination information in the current downlink channel state information and the historical downlink channel state information and the set bandwidth of the network equipment during scheduling.
The transport block refers to TBsize, which represents PRB (Physical Resource Block ) resources required for transmission, that is, a data block size on one subframe or one code stream. In order to realize the scheduling of maximum flow for the terminal by the base station under the set bandwidth so as to improve the throughput of the system, the size of the transmission block corresponding to each combination information needs to be calculated.
In some embodiments, when calculating the size of the transport block, the corresponding modulation order and the target code rate may be obtained according to the SINR in each combination information, and then the size of the transport block corresponding to each combination information may be calculated according to the corresponding modulation order and the target code rate of each combination information, the RI, the set bandwidth of the network device during scheduling, and the number of subcarriers RE.
The specific calculation formula can be as follows:
TBsize＝RI*RBNum*Q*TC*12*symbol；
wherein RI is RI in each combination information, RBNum refers to a set bandwidth of the network device, that is, BWP,12 refers to the number of REs, Q refers to a modulation order corresponding to MCS scheduling, TC refers to a target code rate corresponding to MCS scheduling, Q and TC may be obtained through a mapping table (that is, a mapping table of SINR and Q and TC of MCS) according to SINR in each combination information, and the mapping table may be obtained through simulation.
Therefore, the transport block size corresponding to each combination information can be obtained according to the above calculation formula, i.e. n+1 transport block sizes are obtained.
Step S140: and determining a target SINR in the combined information with the maximum transmission block size, and acquiring and reporting CQI corresponding to the target SINR.
In order to enable the base station to schedule the maximum traffic for the terminal under the set bandwidth, the combination information with the largest transport block size may be selected from the combination information, for example, the combination information corresponding to the largest transport block size is determined from the n+1 transport block sizes, the combination information may be referred to as target combination information, and RI and SINR in the target combination information may be referred to as target RI and target SINR, so that the target SINR may be obtained. Then, when the CQI is acquired, the CQI corresponding to the target SINR may be found according to a mapping table of SINR and CQI obtained in advance through simulation, and then the CQI may be reported to the base station. Of course, when the base station performs MCS scheduling, the base station may also perform scheduling based on RI and/or PMI, so the terminal may also report the target RI, CQI and PMI to the base station together, so that the subsequent base station may schedule the terminal according to the information reported by the terminal, for example, the base station performs channel mapping according to the number of transmission channels indicated by RI, selects a precoding matrix from a fixed codebook according to the PMI indication, performs precoding, and determines the modulation coding mode and transmission efficiency adopted by each codeword according to the CQI index.
After reporting the information, the terminal may store the current RI and the current SINR that are currently measured as combined information in the historical downlink channel state information, that is, the current RI and the current SINR become historical information, so that when the terminal reports the information next time, the terminal also continues to acquire the corresponding CQI according to the above manner for reporting.
In the implementation process, by acquiring the current downlink channel state information and the n+1 combination information consisting of RI and SINR in the historical downlink channel state information, then calculating the corresponding transport block size of each combination information under the set bandwidth of the network equipment, then selecting the target SINR in the combination information with the largest transport block size, and acquiring the CQI corresponding to the target SINR for reporting, the base station can schedule the maximum flow rate by the largest transport block when scheduling the terminal, so that the base station can furthest utilize the transmission capacity of the wireless channel and improve the throughput of the system.
On the basis of the above embodiment, since the historical downlink channel state information is information including all downlink channel state information before the current time, it may contain more information and have longer time, and if the finally obtained target SINR is SINR in one combination information in which the time is longer, the CQI obtained based on this SINR may be time-ineffective and inaccurate. To avoid this problem, the acquired history downlink channel state information may be history downlink channel state information in a set period of time before the current time (because the wireless environment is slowly changing in a short time, history downlink channel state information in a short time may be acquired). For example, each piece of combined information in all pieces of historical downlink channel state information is provided with a corresponding timestamp, wherein the timestamp refers to the time when the combined information is obtained by measurement, so that the combined information can be screened according to the timestamp to screen out the combined information in a set time period before the current time, and the combined information can be used as the obtained historical downlink channel state information. For example, all the historical downlink channel state information includes M pieces of combination information, M is greater than or equal to N, then screening is performed according to the timestamp, N pieces of combination information satisfying the condition after screening are selected, and then the N pieces of combination information and the currently obtained combination information are subjected to transport block size calculation.
In other embodiments, to avoid that the acquired CQI is time-efficient, a timer may be maintained for each combination information obtained in the history, i.e. a timer may be started after each measurement of the obtained combination information, and then, when the historical downlink channel state information is acquired, the combination information without time-out of the timer may be screened out as the historical downlink channel state information. The implementation process comprises the following steps: the method comprises the steps of obtaining initial historical downlink channel state information, wherein the initial historical downlink channel state information can refer to all historical downlink channel state information, or can refer to historical downlink channel state information in a last period of time, the initial historical downlink channel state information comprises M pieces of combined information formed by historical RI and historical SINR, M is greater than or equal to N, each piece of combined information is configured with a timer, then N pieces of combined information in which the timer is not overtime can be obtained through screening, the N pieces of combined information can be used as the historical downlink channel state information, and the N pieces of combined information obtained in the way are all effective combined information.
For example, after each time one piece of combined information is obtained, a timer is configured for the combined information, and the timer is started, and the corresponding time of each piece of combined information can be the same or different, and can be flexibly set according to actual requirements, so that when N pieces of combined information are obtained, whether the timer is overtime or not can be checked, and if the timer is not overtime, the combined information without overtime is taken as one of the N pieces of combined information.
In the implementation process, the N pieces of combined information obtained in the above manner are combined information in a short time, and the variation of the combined information is not very different from the currently obtained combined information, so that the CQI and RI obtained in the manner are combined information enabling the base station to schedule at the maximum flow, and thus the terminal reports the information, and the variation of the maximum flow can be more gentle.
The process of the first SINR and the second SINR acquisition is described in detail below.
On the basis of the above embodiment, the first SINR may be obtained by, as shown in fig. 2, including the following steps:
step S210: and receiving a reference signal sent by the network equipment.
The reference signal, such as CRS or CSI-RS described above, is generated by the base station to the terminal, e.g., the base station transmits to the terminal on a specific time-frequency resource at a specified period.
Step S220: and carrying out channel measurement according to the reference signal to acquire the current RI and the initial SINR.
The current RI and the initial SINR are obtained by measuring the reference signal, and the RI is measured in the manner described in the above embodiment, which is not repeated here. The SINR measurement may be that the terminal measures the power of the obtained reference signal and the power of the measured interference signal, and then the ratio of the two powers is the SINR.
Step S230: and judging whether the timer corresponding to the current RI is overtime, if not, executing the step S240, and if so, executing the step S250.
Due to the instantaneity of channel measurement, the situation that the deviation of CQI obtained by a certain measurement is larger may occur, and according to the specific situation of the terminal, it may be assumed that the channel does not change drastically in a short time, and in actual situation, the error of one measurement is larger due to the instant interference of the channel, and the situation that the error of the obtained CQI is larger may occur at this time. Therefore, in order to eliminate the transient error of the single measurement, the output curve of the SINR is smoothed to be more practical. In the embodiment of the present application, a timer is maintained for each RI (after each new RI is measured, a timer is started for the new RI), that is, after each measurement of the terminal obtains the RI and the SINR (which may be referred to as initial SINR at this time), then it is determined whether the timer maintained by the RI is overtime, if the timer is overtime, it indicates that the historical value has failed, the initial SINR is directly used as the first SINR under the RI, and if the historical value is not overtime, filtering is performed in combination with the historical value.
For example, if the current RI currently measured by the terminal is 2, the terminal starts a timer when the RI historically measured by the terminal is 2, and after the terminal measures the current RI, the terminal determines whether the timer corresponding to the historical RI 2 is overtime. If the RI currently measured by the terminal does not have a corresponding timer, the current RI is reported for the first time, then a timer of the RI is started, and then the initial SINR currently measured is directly used as the first SINR.
Step S240: and filtering the initial SINR and the SINR obtained by measuring the reference signal last time to obtain a processed first SINR.
If the timer corresponding to the current RI does not timeout, the historical SINR corresponding to the historical RI, that is, the historical SINR corresponding to the RI obtained by the last measurement, for example, SINR1, may be obtained, and then the SINR1 and the initial SINR may be smoothed, or other filtering methods may be adopted to perform processing, and finally, the SINR after the filtering process may be obtained as the first SINR.
Step S250: the initial SINR is taken as the first SINR.
If the timer times out, the historical value is invalid, and the current measured initial SINR is directly taken as the first SINR.
After the first SINR is obtained, the timer corresponding to the RI is restarted, and then the historical SINR corresponding to the historical RI is replaced with the first SINR, for example, the SINR1 is replaced with the first SINR, and at this time, the SINR corresponding to ri=2 is the first SINR, so that when the measurement is performed next time, the processing is continued according to the above steps.
In the implementation process, whether the historical SINR is utilized for filtering is determined through whether the timer maintained by the RI is overtime, so that the transient error of single measurement can be eliminated, the obtained SINR is more accurate, and the actual situation is more met.
On the basis of the above embodiment, in order to ensure the accuracy of measurement, after the initial SINR is obtained, it may be further determined whether the initial SINR exceeds a first preset threshold, if so, whether the timer corresponding to the current RI is overtime is further determined.
That is, whether the initial SINR exceeds the first preset threshold may determine whether the received reference signal is the reference signal to be measured currently, if not, the received reference signal may be discarded directly, if so, the reference signal may be discarded directly, and subsequent processing may be continued, so that it may be ensured that the subsequently measured SINR is more accurate.
On the basis of the above embodiment, the second SINR may be obtained by: and the receiving network equipment checks the data transmitted by the PDSCH to obtain a check result, and adjusts the preset SINR according to the check result to obtain an adjusted second SINR.
The data may be checked by calculating a block error rate of the data and then checking a calculation result. The block error rate is a way of characterizing the data transmission accuracy, in practical application, the block error rate can be obtained by periodically counting the CRC check code of the received data, and the ratio of the number of CRC check errors to the total counted number of frames is the block error rate in the counted period. If the block error rate is smaller than the preset block error rate, the check result is indicated to be check passing, at this time, a first value can be added on the basis of the preset SINR, the obtained sum value is a second SINR, if the block error rate is larger than or equal to the preset block error rate, the check result is indicated to be check failing, at this time, the second value can be subtracted on the basis of the preset SINR, and the obtained difference value is the second SINR.
Since the transmission power in the LTE downlink is constant, in order to adapt to rapid changes of the radio channel, the LTE adopts different link adaptation calculations, including a method of combining inner loop link adaptation and outer loop link adaptation. The inner loop link adaptation is to select an appropriate MCS for the terminal based on the obtained SINR, the outer loop link adaptation is to achieve the target BLER by adjusting the MCS, for example, the target bler=0.1 in LTE, and the base station may determine the current BLER by counting HARQ-ACKs (Hybrid Automatic Repeat Request, hybrid automatic repeat) fed back by the terminal, which is based on HARQ-ACK feedback information of the first transmission of the hybrid automatic repeat HARQ.
In HARQ technology, a base station needs to retransmit a packet with a retransmission error, so that the influence of time variation of a wireless mobile channel and multipath fading on signal transmission can be well compensated. Therefore, after receiving the data, the terminal firstly judges whether the data is first transmission data or retransmission data, if the data is first transmission data, the data is decoded, if the data is decoded correctly, the terminal generates ACK if the verification passes, and if the data is decoded incorrectly, the terminal generates NACK if the verification does not pass. The generated ACK or NACK is called HARQ-ACK acknowledgement information, the terminal feeds back the acknowledgement information to the base station, and the base station can judge whether the data needs to be retransmitted or not according to the acknowledgement information.
As will be appreciated in connection with fig. 3, the obtaining of the second SINR includes the following steps:
step S310: judging the confidence coefficient;
step S320: acquiring corresponding MCS scheduling information;
step S330: judging whether the data is transmitted for the first time, namely whether the data is newly transmitted;
step S340: the terminal judges whether the data passes the verification;
step S350: if the data check is passed, it is determined whether the obtained scheduling MCS is less than the maintenance MCS, and if so, step S360 is executed: taking the preset SINR as the second SINR, if the preset SINR is greater than or equal to the second SINR, executing step S370: adding the first value to the preset SINR to obtain a second SINR;
step S380: if the data check is not passed, it is determined whether the obtained scheduling MCS is less than the maintenance MCS, and if so, step S390 is executed: subtracting the second value from the preset SINR to obtain a second SINR, and if the second SINR is greater than or equal to the second SINR, executing step S400: subtracting a third value from the preset SINR to obtain a second SINR;
step S410: if the received data is not the first transmission data, checking the data, and judging whether the data passes the check;
if the data check passes, step S420 is executed: taking the preset SINR as the second SINR, if the data check is not passed, executing step S430: subtracting the second value from the preset SINR to obtain a second SINR.
Specifically, if the data is first transmitted data, after the terminal checks the data, if the data does not pass the check, NACK is generated, if the data passes the check, ACK is generated, if the terminal generates ACK, it is continuously determined whether the scheduling MCS acquired from the base station is smaller than the historical maintenance MCS (refer to the last acquired MCS), if yes, the preset SINR is maintained, that is, the preset SINR is taken as the second SINR at this time, and if not, the first value is added to the preset SINR to obtain the second SINR. And if the check is not passed, generating NACK, then continuously judging whether the dispatching MCS obtained from the base station is smaller than the historical maintenance MCS, if so, subtracting a second value from the preset SINR to obtain a second SINR, and if not, subtracting a third value from the preset SINR to obtain the second SINR.
If the data is not the first transmission data, after the data is checked by the terminal, NACK is generated if the data is not checked, ACK is generated if the data is checked, the preset SINR is used as the second SINR if the ACK is generated by the terminal, and the second value is subtracted from the preset SINR to be used as the second SINR if the NACK is generated by the terminal.
Wherein the preset SINR may be preset according to simulation experiment, and the first value may be delta ack The value may be obtained from practical experiments, and the second value may be αΔ nack Wherein α refers to a linear filter factor, Δ nack Can be according to delta ack The method is obtained by adopting the following calculation formula: bler=Δ ack /(Δ ack +Δ nack ) Wherein the BLER may be obtained in advance, and the third value may be Δ nack 。
Therefore, according to the method, the preset SINR can be correspondingly corrected, then the second SINR for measuring the channel is obtained, so that the more accurate second SINR can be obtained, the CQI corresponding to the SINR is obtained after the first SINR and the second SINR are weighted and summed, the obtained CQI is more accurate, the more accurate CQI is reported to the base station, better throughput can be obtained, and better matching of the actual channel receiving capability and the data transmission rate of the terminal can be realized.
In addition, after the second SINR is obtained, before the second SINR and the first SINR are weighted and summed, whether the timer of the RI corresponding to the first SINR is overtime may be further determined, if not, the current SINR is obtained after the first SINR and the second SINR are weighted and summed, and the process may be as shown in fig. 4; if the time-out is over, the first SINR can be directly used as the current SINR without carrying out weighted summation, so that the obtained current SINR is ensured to be closer to the actual situation.
In the step S310, in order to determine whether the obtained second SINR is accurate, a confidence determination may be performed in advance, which specifically includes: measuring a demodulation reference signal of the PDSCH to obtain a reference SINR, judging whether the reference SINR exceeds a second preset threshold value (the value can be flexibly set according to actual requirements), and if so, executing the steps of: and checking the data to obtain a checking result.
The demodulation reference signal is used for demodulating data of the PDSCH signal, which is also generated by the base station for the terminal, so that the demodulation reference signal can be measured in the manner of measuring the reference signal, the reference SINR is obtained, whether the reference SINR exceeds a second preset threshold value (which can be flexibly set according to actual requirements) is judged, if so, the noise of the current channel is considered to be satisfactory, that is, the demodulation reference signal is considered to be satisfactory, the subsequent steps can be continued, if not, the noise of the current channel is considered to be larger, the demodulation reference signal is not satisfactory, and possibly the subsequently demodulated data is inaccurate, so that the signal can be discarded, and the next demodulation reference signal is waited to be continuously processed, thus, the instantaneous fluctuation of the measurement result can be avoided, and the subsequently obtained SINR is ensured to be truly effective.
