Embodiments of the invention some exemplary embodiments have been described for illustrative purposes, it being understood that the invention may be practiced otherwise than as specifically shown in the accompanying drawings.
The foregoing implementations are described in detail below with reference to specific embodiments and accompanying drawings.
As shown in fig. 1, a schematic diagram of DSS networking is shown. The DSS networking network can comprise an NR exclusive spectrum and an NR and LTE shared spectrum, wherein the NR and LTE shared spectrum refers to that an NR system and an LTE system are deployed in the same frequency band, and the exclusive spectrum and the shared spectrum form the full-band spectrum of the DSS networking network together. Wherein, the channel state information (channel state information, CSI) of the NR unshared spectrum is a first set of periodic CSI, and the CSI of the full band spectrum is a second set of periodic CSI.
For example, if the full band spectrum of the DSS networking network is 40M, the NR exclusive spectrum may be 20M, and the shared spectrum of NR and LTE may be another 20M.
The scheduling frequency band configured by the base station side for the electronic equipment can be a full-band frequency spectrum or a single-shared frequency spectrum. Under the condition that the LTE in the shared spectrum does not have adjacent cell interference, if the electronic equipment scheduling frequency band is a full-band frequency spectrum, the utilization of all spectrum resources can be realized, so that the throughput is improved, and at the moment, the frequency band scheduled by the electronic equipment is preferably the full-band frequency spectrum. When adjacent cell interference exists in the LTE in the shared spectrum and the interference is large, the channel quality of the scheduled full-band spectrum is reduced due to the interference of part of the frequency bands, so that the throughput of the scheduled full-band spectrum is smaller than that of the scheduled exclusive-band spectrum, and the frequency bands scheduled by the electronic equipment are preferably the exclusive-band spectrum. Therefore, in order to ensure throughput and improve spectrum resource utilization, the present invention aims to solve the problem of how to determine the optimal scheduling band of an electronic device from a shared-nothing spectrum and a full-band spectrum.
It should be noted that, the electronic device in the embodiment of the present invention needs to have the following requirements:
(1) Supporting a ZP-CSI-RS resource set, wherein the resource set is necessary configuration for DSS dynamic spectrum sharing;
(2) Support full band spectrum bandwidth and unshared spectrum bandwidth, such as support 20M bandwidth and 40M bandwidth;
as shown in fig. 2, an embodiment of the present invention provides a frequency band adjustment method, which can be applied to a base station device on a base station side. The frequency band adjustment method may include S101-S102:
s101, under the condition that a scheduling frequency band of the electronic equipment is a first frequency band, determining first frequency spectrum efficiency of the first frequency band and second frequency spectrum efficiency of a second frequency band.
Wherein the first frequency band is a single frequency spectrum, and the second frequency band is a full frequency spectrum; alternatively, the first frequency band is a full band spectrum and the second frequency band is a single shared spectrum.
Optionally, before determining the first spectral efficiency of the first frequency band and the second spectral efficiency of the second frequency band, the base station device may start a first sliding window schn_num of length N, which may be used for sliding statistics of the correlation results measured in the N scheduling. The base station device may also configure a first set of periodic CSI reports for the unshared spectrum, the periodic CSI reports associated periodic CSI-RS measurements, and configure a second set of periodic CSI reports for the full-band spectrum, the periodic CSI reports associated periodic CSI-RS measurements.
Optionally, the base station device may configure channel state information reference signals for the first frequency band and the second frequency band, where the channel state information reference signals are used by the electronic device to measure channel state information of the corresponding frequency band, and the channel state information includes: channel quality indication and rank indication; receiving channel state information of the first frequency band and channel state information of the second frequency band, which are reported by electronic equipment; respectively counting channel state information of a first frequency band and channel state information of a second frequency band in a first sliding window; and determining the first frequency spectrum efficiency according to the channel state information of the first frequency band, and determining the second frequency spectrum efficiency according to the channel state information of the second frequency band.
Specifically, taking the first frequency band as the exclusive spectrum, the second frequency band as the full-band spectrum as an example. The base station equipment can configure channel state information reference signals for a first frequency band and a second frequency band respectively, the electronic equipment can measure the channel state information of the first frequency band through the channel state information reference signals of the first frequency band and report the channel state information of the first frequency band, and similarly, the electronic equipment can measure the channel state information of the second frequency band through the channel state information reference signals of the second frequency band and report the channel state information of the second frequency band, and the base station equipment can receive the channel state information of the first frequency band and the channel state information of the second frequency band reported by the electronic equipment; and in the first sliding window schn_num, counting channel state information 1 in M first periodic CSI reporting measurement results, counting channel state information 2 in K second periodic CSI reporting measurement results, wherein the channel state information may include channel quality indication (Channel Quality Indicator, CQI) and Rank Indication (RI), and then the base station device may calculate an average value of the CQI in the first sliding window schn_num in the channel state information 1, and record the average value as CQI0 in the first sliding window schn_num, calculate an average value as RI0 in the second sliding window schn_num in the channel state information 2, and record the average value as CQI1 in the second sliding window schn_num in the RI. Then, a first spectral efficiency SE0 is determined from CQI0 and RI0, and a second spectral efficiency SE1 is determined from CQI1 and RI1.
It should be noted that, since the spectrum efficiency SE is approximately equal to RI and the modulation and coding strategy (Modulation and Coding Scheme, MCS), while MCS is mainly determined by the inner-loop CQI, which is then fine-tuned by the outer-loop, the spectral efficiency SE can be approximated by the product of CQI and RI. I.e. SE0 = CQI0RI0，SE1= CQI1/>RI1。
Illustratively, if CQIs 0=14.8, rl0=2.4, CQIs 1=13.2, rl1=1.9, then the first spectral efficiency SE 0=cqis 0RI0=14.8/>2.4 Second spectral efficiency SE1 = CQI1 +. 35.52>RI1=13.2/>1.9=25.08。
It should be noted that CQI and RI may be used to represent channel quality indicators of the spectrum. I.e., CQI0 and RI0 may be used to represent channel quality indicators of the unshared spectrum, and CQI1 and RI1 may be used to represent channel quality indicators of the full band spectrum.
Optionally, the above M is a ratio of the first sliding window length N to the first group reporting period. K is the ratio of the length N of the first sliding window to the reporting period of the second group. Since periodic CSI reporting is periodic, i.e., not reported every time of scheduling, a sliding window with a window length of N can only count M or K periodic CSI reporting.
For example, if the first sliding window length N is 80 and the first reporting period is 20ms, the base station device may count 4 channel state information in the first periodic CSI reporting measurement results.
S102, if the first frequency spectrum efficiency is smaller than the product of the second frequency spectrum efficiency and a preset proportionality coefficient, adjusting the scheduling frequency band of the electronic equipment from the first frequency band to the second frequency band.
It should be noted that, the base station device may perform bandwidth conversion on the first spectrum efficiency SE0 and the second spectrum efficiency SE1 based on the preset scaling factor, so as to eliminate the influence of the resource difference of the two spectrums on the final result. The preset scaling factor may be a fixed value determined based on simulation techniques and empirical values.
Optionally, if the first spectral efficiency SE0 is smaller than the product of the second spectral efficiency SE1 and the preset scaling factor, it indicates that the communication quality of the second frequency band is better, so that the scheduling frequency band of the electronic device can be adjusted from the first frequency band to the second frequency band.
Alternatively, the base station device may perform limitation of the scheduling spectrum of the electronic device by limiting the available RB positions or actively allocating available RBs to the electronic device. For example, taking limitation of the electronic device scheduling spectrum by limiting the available RB positions as an example, the base station side may limit the RB Start position rb_start and the RB Length rb_length, thereby implementing limitation of the electronic device scheduling spectrum.
For example, taking a full-band spectrum of the DSS networking network as 40M, the number of RBs corresponding to the full-band spectrum is 0 to 215, where 0 to 105 is an NR unshared spectrum of 20M, and 106 to 215 is a shared spectrum of NR and LTE of 20M as an example, if the scheduling frequency band of the electronic device is the NR unshared spectrum, the base station device may limit the available RB positions of the electronic device to 0 to 105, so as to limit the electronic device to scheduling in the unshared spectrum.
In the embodiment of the invention, the scheduling frequency band of the electronic equipment can be adjusted from the first frequency band to the second frequency band when the first frequency spectrum efficiency is smaller than the product of the second frequency spectrum efficiency and the preset proportionality coefficient, so that the problems that only the exclusive frequency spectrum is used to cause the waste of frequency spectrum resources and only the full frequency spectrum is used to cause serious reduction of channel quality due to adjacent cell interference can be avoided, and the optimal scheduling frequency band can be determined from the exclusive frequency spectrum and the full frequency spectrum, thereby improving the selection flexibility of the scheduling frequency band and further improving the user experience and the frequency spectrum utilization rate.
Optionally, as shown in fig. 3, after S101 and before S102, the above-mentioned frequency band adjustment method may further include S103; after S103, the above-mentioned frequency band adjustment method may further include S104:
s103, judging whether the first frequency spectrum efficiency is smaller than the product of the second frequency spectrum efficiency and a preset proportionality coefficient.
And S104, if the first frequency spectrum efficiency is greater than or equal to the product of the second frequency spectrum efficiency and the preset proportionality coefficient, keeping the scheduling frequency band of the electronic equipment to be the first frequency band.
Optionally, if the first spectral efficiency SE0 is greater than or equal to the product of the second spectral efficiency SE1 and the preset scaling factor, this indicates that the communication quality of the first frequency band is better, so that the frequency band switching may not be performed.
In the embodiment of the invention, the scheduling frequency band of the electronic equipment is kept to be the first frequency band under the condition that the first frequency spectrum efficiency is larger than or equal to the product of the second frequency spectrum efficiency and the preset proportionality coefficient, so that the current frequency band can be ensured to be the optimal scheduling frequency band, and the user experience is improved.
Optionally, with continued reference to fig. 3, after the scheduled frequency band of the electronic device is switched from the first frequency band to the second frequency band, the above frequency band adjustment method may further include S105-S108:
s105, determining the average transport block size in the first frequency band and the average transport block size in the second frequency band.
Optionally, the base station device may start a first scheduling window schl_num and a second scheduling window schs_num, where the first scheduling window schl_num is used to count the number of scheduling times before the scheduled frequency band is switched, the second scheduling window schs_num is used to count the number of scheduling times after the scheduled frequency band is switched, and the length of the second scheduling window schs_num is smaller than that of the first scheduling window schl_num.
Optionally, the first scheduling window schl_num may be a first sliding window schn_num, that is, the base station device may count the number of scheduling times before the scheduling frequency band is switched through the first sliding window schn_num.
Optionally, the base station device may acquire first information and second information of the electronic device, where the first information is used to indicate a transmission indicator in a first frequency band in the first scheduling window, and the second information is used to indicate a transmission indicator in a second frequency band in the second scheduling window; calculating the average transmission block size in the first frequency band according to the first information, and calculating the average transmission block size in the second frequency band according to the second information; wherein the length of the second scheduling window is smaller than the length of the first scheduling window.
Optionally, the first information may include: average MCS within the first scheduling window, average RI within the first scheduling window, and average scheduling RB within the first scheduling window. The second information may include: average MCS within the second scheduling window, average RI within the second scheduling window, and average scheduling RB within the second scheduling window.
Specifically, the base station device may respectively count the first information and the second information of the electronic device, and then calculate to obtain an average transport block size tbsize_before in the first frequency band according to the average MCS in the first scheduling window, the average RI in the first scheduling window, and the average RB in the first scheduling window, and calculate to obtain an average transport block size tbsize_after in the second frequency band according to the average MCS in the second scheduling window, the average RI in the second scheduling window, and the average RB in the second scheduling window.
Optionally, the base station device may count the first information through a first scheduling window before the current frequency band switching occurs, and count the second information through a second scheduling window after the current frequency band switching occurs.
Based on the above scheme, since the length of the second scheduling window is smaller than that of the first scheduling window, statistics of scheduling times can be rapidly realized after the scheduling frequency band of the base station equipment is switched from the first frequency band to the second frequency band, so that the problem that the electronic equipment needs to be in the second frequency band for a long time after the frequency band is switched under the condition that the first frequency band is better than the second frequency band is avoided.
It should be noted that the average transport block size may reflect the size of the transport block, and the larger the transport block, the more data it can carry, and thus the size of the data throughput may be reflected by the average transport block size.
It should be noted that, since higher spectral efficiency does not mean higher data transmission rate, spectral efficiency is only an index reflecting one dimension of data transmission rate, it is necessary to determine the size of data throughput before and after switching by comparing average transport block sizes after switching the scheduling frequency band, and further determine whether rollback processing is required.
S106, judging whether the average transport block size in the first frequency band is larger than the average transport block size in the second frequency band.
And S107, when the average transport block size in the first frequency band is larger than the average transport block size in the second frequency band, readjusting the scheduling frequency band of the electronic equipment to the first frequency band.
S108, when the average transport block size in the first frequency band is smaller than or equal to the average transport block size in the second frequency band, maintaining the scheduling frequency band of the electronic device as the first frequency band.
Optionally, if the electronic device does not switch the scheduling frequency band, the base station device may control the first sliding window schn_num to slide by a unit length; because the resources in the second scheduling window are judged through the rollback mechanism, if the electronic device switches the scheduling frequency bands, the base station device can control the first sliding window schn_num to directly slide for L unit lengths, wherein L is the length of the second scheduling window.
In the embodiment of the invention, the data throughput before and after the frequency band switching can be determined through the comparison of the average transmission block sizes, so that the current optimal scheduling frequency band can be further judged and selected, the flexibility of selecting the scheduling frequency band is improved, and the user experience and the frequency spectrum utilization rate are further improved.
