The 40M DSS technology is implemented as shown in fig. 1, and a 40M NR +20M LTE (where 20M is an LTE/NR shared area) is adopted, in a 40M DSS tandem networking, because an LTE cell mod3 where LNRs share bandwidth is planned, the shared area of the 40M DSS may be subject to co-channel interference. Even if the LTE load is not high, due to the continuous transmission of CRS, the NR terminal still suffers from severe interference at the cell boundary, which may cause the NR terminal to have poor channel quality and high error rate when scheduling 40M bandwidth, so that the MCS reduced terminal rate is greatly reduced, and even a very large rate is reduced to be lower than the NR shared bandwidth scheduled by 20M.
At present, the optimization mode of most manufacturers is to adopt a dynamic frequency selection scheduling algorithm, that is, when the interference of LTE is serious, NR terminals schedule only 20M bandwidth of an exclusive spectrum, which may cause the disadvantages of excessive waste of NR spectrum resources, significant performance degradation of 5G networks, and the like, and the current industry needs an algorithm to allow NR terminals to schedule 40M bandwidth as much as possible under the condition of avoiding interference of LTE CRS.

In the prior art, an nr (new radio) terminal is also called a new air interface, and a mobile communication system mainly includes three subsystems, namely, a terminal, a base station, and a core network. The terminal and the base station form a base station subsystem, and a plurality of complex network elements inside the core network form a network subsystem. The terminals are typically mobile phones, the base stations are used to transmit signals, and the core network is similar to a router, connecting the base stations together so that they can communicate with each other. The interface between the mobile phone and the base station is called an "air interface" because the base station and the mobile phone are propagated in the air through electromagnetic waves. No matter the connected core network is EPC of 4G or 5GC of 5G, the same mobile phone has two air interface connections, the link with the 4G base station is the 'old air interface', and the connection with the 5G base station is the 'new air interface'.
As described above, most manufacturers currently adopt a dynamic frequency selection scheduling algorithm, that is, when the interference from LTE is serious, the NR terminal only schedules the bandwidth of 20M independent spectrum, which may cause the disadvantages of excessive waste of NR spectrum resources, significant performance degradation of 5G network, and the like. In order to enable the NR terminal to schedule 40MHz as much as possible in the 40M DSS network, the scheduling method of the dynamic spectrum sharing network that can be used in the present application can also be a method for countering CRS interference in the 40M DSS networking. The method is based on a multi-graph rate matching algorithm, a plurality of sets of rate matching graphs are prepared on a base station side, the self-checking condition of a terminal is informed to the base station side, the base station matches the corresponding rate matching graphs to the terminal, and the granularity of time-frequency resources punched by the graphs is self-adaptive between RE level and symbol level. By applying the method, the NR terminal can sacrifice a small amount of time-frequency resources to avoid CRS interference, and the purpose that the performance of scheduling 40MHz large bandwidth is obviously superior to that of scheduling 20MHz single-shared spectrum is realized.
The following is a detailed description with the aid of specific examples.
Fig. 2 is a system block diagram illustrating a scheduling method and apparatus for a dynamic spectrum sharing network according to an exemplary embodiment.
As shown in fig. 2, the system architecture 20 may include NR terminal devices 201, 202, 203 and a base station 204. A user may use the NR terminal devices 201, 202, 203 to interact with other NR terminals or servers through the base station 204 to receive or transmit messages or the like. Various communication client applications, web browser applications, search applications, instant messaging tools, mailbox clients, social platform software, and the like may be installed on the NR terminal devices 201, 202, and 203.
The NR terminal devices 201, 202, 203 may be various electronic devices having a display screen and supporting web browsing, including but not limited to smart phones, tablet computers, laptop portable computers, desktop computers, and the like.
The NR terminal devices 201, 202, 203 may generate commodity information from the commodity own data, for example; NR terminal devices 201, 202, 203 may generate enterprise information, for example, from commodity selling merchant data; the NR terminal device 201, 202, 203 may store the enterprise information into blocks of a blockchain, for example, by a blockchain protocol, and generate signature information; the NR terminal devices 201, 202, 203 can generate commodity distribution information from the commodity information and the signature information, for example.
The base station 204 may, for example, allocate a first picture to an NR terminal for rate matching after detecting that the NR terminal accesses a dynamic spectrum sharing network; the base station 204 may allocate, for example, when receiving a map number from an NR terminal, a second map, a third map, or a fourth map corresponding to the map number to the NR terminal for rate matching.
It should be noted that the scheduling method of the dynamic spectrum sharing network provided in the embodiment of the present application may be executed by the NR terminal devices 201, 202, and 203 and the base station 204, and accordingly, the scheduling apparatus of the dynamic spectrum sharing network may be disposed in the NR terminal devices 201, 202, and 203 and the base station 204.
Fig. 3 is a flowchart illustrating a scheduling method of a dynamic spectrum sharing network according to an example embodiment. The scheduling method 30 of the dynamic spectrum sharing network can be applied to an NR terminal, and at least includes steps S302 to S308.
As shown in fig. 3, in S302, the NR terminal accesses the dynamic spectrum sharing network and initiates a service. Further comprising: the base station issues a first map to the NR terminal; and the NR terminal performs rate matching according to the first map.
In S304, the signal-to-noise ratio of the NR terminal is acquired in real time. Signal-to-Interference plus Noise Ratio (SINR), the Signal-to-Interference plus Noise Ratio (SINR) refers to the Ratio of the received strength of the desired Signal to the received strength of the interfering Signal (Noise and Interference).
In S306, when the signal-to-noise ratio is smaller than the threshold, the NR terminal performs self-test to generate a profile number. And the NR terminal carries out self-checking based on the CRS-IC scheme to generate the map number. Fig. 4 exemplarily shows a diagram corresponding to the rate matching map numbers 1,2,3, 4. Different boxes respectively show the channels of the region, and can include:
the LTE PDCCH (Physical Downlink Control Channel) refers to a Physical Downlink Control Channel. The PDCCH carries scheduling and other control information, specifically including transport format, resource allocation, uplink scheduling grant, power control, uplink retransmission information, and the like.
The LTE CRS Cell Reference Signal may be used for downlink channel quality measurement and downlink channel estimation, and is used for coherent detection and demodulation at the UE end. Each downlink sub-frame has a downlink pilot time slot of the special sub-frame. Within an RB, every six subcarriers are a reference signal in the frequency domain, every three symbol bits in the time domain, and the specific position arrangement is related to CELLID.
CRS knocked out by rate matching;
the PDSCH and PDSCH (Physical Downlink Shared Channel) available for NR is one of LTE Physical Downlink channels, which is a Downlink Channel for LTE to carry main user data, all user data can be used, and the PDSCH and PDSCH also include system broadcast messages and paging messages that are not transmitted in PBCH, and no specific Physical layer paging Channel in LTE.
More specifically, 4 sets of rate matching maps for the 20M LNR shared region may be stored in advance on the base station side, as shown in fig. 4. The position of the CRS may be recorded by using a field vshift, where map 1 shows that the time-frequency resource corresponding to the CRS with vshift equal to 0 on the symbol 4/7/8/11 is removed by rate matching, map 2 shows that the time-frequency resource corresponding to the CRS with vshift equal to 0+ vshift equal to 2 on the symbol 4/7/8/11 is removed by rate matching, map 3 shows that the time-frequency resource corresponding to the CRS with vshift equal to 0+ vshift equal to 1 on the symbol 4/7/8/11 is removed by rate matching, and map 4 shows that the whole symbol 4/7/8/11 is removed by rate matching. The base station does not transmit the NR PDSCH at the position of the punch of the map, and the NR terminal does not decode the PDSCH at the position of the punch.
In one embodiment, when the CRS-IC self-test result meets a first policy, an atlas number 00 is generated, corresponding to atlas 1; in one embodiment, when the CRS-IC self-test result meets the second policy, an atlas number 01 is generated, corresponding to atlas 2; in one embodiment, when the CRS-IC self-test result satisfies the third policy, an atlas number 10 is generated, corresponding to the atlas 3; in one embodiment, when the CRS-IC self-test result satisfies the fourth policy, a profile number 11 is generated, corresponding to profile 4.
Due to the existence of the CRS of the 20M LTE cell of the 40M DSS, when the signal-to-noise ratio is high, the CRS interference of the 40M DSS network is avoided by using the spectrum 1 for rate matching. The terminal self-detects the position of an adjacent cell interfering CRS through a CRS-IC scheme, reports a 2-bit map number field to a base station through UCI, if the CRS-IC self-detection is only interfered with a shift of 0, the CRS-IC self-detection reports a map number field 00, if the shift of 0+ the shift of 2 is interfered with a report field 01, if the shift of 0+ the shift of 2 is interfered with a field 10, and if more surrounding regions are interfered with shared regions, the CRS-IC self-detection reports a field 11, and the situations correspond to rate matching maps 1-4 respectively.
In S308, the map number is sent to the base station for scheduling of the dynamic spectrum sharing network. Sending the map number to a base station; and the base station issues a second map, a third map or a fourth map to the NR terminal according to the map number.
In one embodiment, the base station terminal needs to cooperate with an instruction of the NR terminal to perform processing, which may include that, after detecting that the NR terminal accesses the dynamic spectrum sharing network, the base station allocates a first picture to the NR terminal for rate matching; when receiving an atlas number from an NR terminal, a base station allocates a second atlas, a third atlas or a fourth atlas corresponding to the atlas number to the NR terminal for rate matching.
According to the scheduling method of the dynamic spectrum sharing network, the NR terminal is accessed into the dynamic spectrum sharing network and initiates a service; acquiring the signal-to-noise ratio of an NR terminal in real time; when the signal-to-noise ratio is smaller than a threshold value, the NR terminal performs self-checking to generate a map number; and the NR terminal can avoid CRS interference by sacrificing a small amount of time-frequency resources, realize dynamic spectrum sharing network scheduling, and solve the defects of spectrum resource waste, obvious performance reduction of a 5G network and the like.
It should be clearly understood that this application describes how to make and use particular examples, but the principles of this application are not limited to any details of these examples. Rather, these principles can be applied to many other embodiments based on the teachings of the present disclosure.
Fig. 5 is a flowchart illustrating a scheduling method of a dynamic spectrum sharing network according to another example embodiment. The process 50 shown in fig. 5 is a detailed description of the process shown in fig. 3.
As shown in fig. 5, the NR terminal accesses the 40M DSS network and starts a service in S501.
In S502, the network matches the rate matching map 1 to the NR terminal.
In S503, the SINR is 10dB or more.
In S504, the terminal starts a self-check, and a 2-bit field of the self-check result is reported to the base station through the UCI.
In S505, when the self-check result is 00, the SINR value continues to be monitored while maintaining pattern 1.
In S506, when the self-test result is 11, the base station configures the graph 4 to the NR terminal through the DCI.
In S507, when the self-test result is 10 or 01. The base station configures the map 2 or 3 to the NR terminal through the DCI.
In S508, the SINR is 5dB or more.
In S509, map 4 is maintained, and the SINR value continues to be monitored.
In S510, the terminal starts a self-check, and a 2-bit field of the self-check result is reported to the base station through the UCI.
In S511, when the self-test result is 11, the SINR value continues to be monitored while maintaining the map 4.
In S512, the SINR is 12dB or greater.
In S513, map 1 is switched back without self-checking.
In S514, the SINR is less than 4dB
At S515, switch back to atlas 4 without self-examination
In S516, map 2 or 3 is maintained, and the SINR value continues to be monitored.
At present, two methods for solving CRS interference in 40M DSS exist, namely 1, a frequency selection scheduling algorithm is used for scheduling a 20M exclusive area, so that the bandwidth is extremely wasted. 2. The rate matching method only drops the REs of the CRS of the 40M DSS, so that the interference is relieved, but serious interference still can occur.
The method provided by the application can realize self-adaptive switching between RE level rate matching and symbol level rate matching, and can use RE level rate matching when the interference is weak and symbol level rate matching when the interference is strong, thereby greatly improving the spectrum efficiency while solving the interference problem.
The method provided by the application can be used for outdoor 40M DSS networking, and after the method is used in the 40M DSS network, the interference influence caused by LTE CRS can be reduced when the NR terminal schedules 40M large bandwidth, so that the effects of improving the average speed of the NR terminal and improving the spectrum utilization rate are achieved.
