Description

Background Art

[0002] At present, in order to balance the capacity requirements of 4G (4th Generation Mobile Communication Technology) / 5G (5th Generation Mobile Communication Technology), a variety of technical solutions will be used on the 2.1 frequency band 40M bandwidth to realize the 5G basic coverage layer and support the growth demand of the existing 4G capacity. For example, 20M LTE (Long Term Evolution) + 20MLTE, 20M LTE + 20M NR (New Radio), 40M NR, 40M DSS (Dynamic Spectrum Sharing). The intersection of these networking technology solutions will have the problem of LTE interfering with NR. The possible boundary interference combinations can be summarized as follows: Figure 1 The three categories shown are 40M NR adjacent to one 20M LTE frequency, 40M NR adjacent to two 20M LTE frequencies, and 20M NR adjacent to 20M LTE. Since LTE CRS (Cell Reference Signal) is continuously sent, LNR interference (LTE interference with NR) is still serious even when the LTE load is low, which may cause the 5G rate to be lower than 4G at the LNR boundary. In order to ensure the user experience of 5G, two circles of isolation belts are often used to solve the LNR boundary interference problem, but the isolation belt will increase the workload of base station frequency clearing, and may also cause discontinuous coverage of NR, and isolation belts cannot be planned in some areas.

[0036] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that the disclosure will be more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

[0037] In addition, the accompanying drawings are only schematic illustrations of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0038] One or more embodiments of the present disclosure provide a method for eliminating boundary interference, which relates to a communication network with an asymmetric bandwidth networking mode. Figure 1 As shown in the figure, when 40M NR and 20M LTE frequencies are adjacent, due to the 20M LTE cell mod3 (also known as mode 3 interference, a form of interference within the LTE system) planning, the same frequency area of ​​40M NR will be interfered by CRS. Even if the LTE load is not high, the NR terminal at the cell boundary will still be seriously interfered, which will cause the channel quality of the NR terminal to deteriorate when scheduling 40M bandwidth, increase the bit error rate, and thus significantly reduce the MCS (Modulation and Coding Scheme) downgraded terminal rate, making the 40M NR network performance may be lower than that of 20M NR or 20M LTE cells.

[0039] It should be noted that Figure 1 The figure only shows one networking form involved in the boundary interference elimination method of the present invention, but the networking form involved in the method is not limited to this one. The method is also applicable to other networking forms, including but not limited to 40M NR and 20MLTE+20M NR, 40M NR and 20M LTE+20M LTE, 40M DSS and 20MLTE+20M LTE, and 40M DSS and 20M LTE+20M NR.

[0040] In order to solve the LNR boundary interference problem, the embodiment of the present disclosure proposes a boundary interference elimination method.

[0041] Figure 2 is a flow chart of a boundary interference elimination method according to one or more embodiments of the present disclosure, the method is applied to a terminal, for example, the method can be executed by the terminal, such as Figure 2 As shown, the method includes:

[0042] Step S202: monitoring the signal and SINR (Signal to Interference plus Noise Ratio) of the terminal;

[0043] For example, the SINR of the terminal may be periodically acquired at preset time intervals, and the acquired SINR may be reported to the network side device so that the network side device can understand the signal reception status of the terminal in real time.

[0044] Step S204: in response to monitoring that the SINR meets a preset condition, obtaining CRS interference information of the terminal;

[0045] Before executing step S202, the terminal may communicate with the network side device based on a certain rate matching spectrum, or may communicate with the network side without using any rate matching spectrum. When the terminal uses different rate matching spectra to communicate with the network side device, the preset conditions are different, and under different preset conditions, the value of the SINR may be different.

[0046] In step S204, the terminal may perform self-check by executing CRS-IC (Common Reference Signal-Interference cancellation) to obtain CRS interference information of the terminal.

[0047] Step S206: determining information of a target rate matching map according to the CRS interference information, wherein the target rate matching map indicates a target position of unavailable time-frequency resources;

[0048] Among them, the target position of the unavailable time-frequency resources in the target rate matching spectrum may correspond to the CRS interference position.

[0049] Optionally, the terminal may pre-store the correspondence between CRS interference information and rate matching spectrum. Based on this, in step S206, the terminal may determine the target rate matching spectrum corresponding to the CRS interference information based on the correspondence, thereby achieving the purpose of rate matching adaptation.

[0050] The unavailable time-frequency resource may be, for example, a time-frequency resource unit consisting of a symbol and a subcarrier, namely, RE (Resouce Element).

[0051] The information of the target rate matching spectrum may include, for example, an identifier of the target rate matching spectrum corresponding to the above-mentioned CRS interference information, or may include information on whether the terminal needs to obtain the CRS spectrum. Based on this information, the network side device may know the target rate matching spectrum required by the terminal, or may know whether the terminal needs to use the rate matching spectrum for communication.

[0052] Step S208: Decoding the signal received from the network-side device using the target rate matching map, wherein no decoding is performed at the target position.

[0053] Optionally, the target rate matching map may simultaneously indicate available time-frequency resources and unavailable time-frequency resources. After receiving the signal sent by the network side device, the terminal may decode the signal at the available time-frequency resource position and not decode the signal at the unavailable time-frequency resource position.

[0054] Optionally, after executing step S208, the SINR of the terminal may continue to be monitored, and based on whether the SINR meets specified conditions, it may be determined whether to switch the rate matching spectrum used by the terminal, or whether the terminal needs to use the rate matching spectrum for communication.

[0055] The boundary interference elimination method of one or more embodiments of the present disclosure monitors the SINR of the terminal, and when it is monitored that the SINR of the terminal meets a preset condition, obtains the CRS interference information of the terminal, and determines the information of the target rate matching spectrum according to the CRS interference information, so that when the terminal receives the signal from the network side device, the target rate matching spectrum can be used to decode the signal from the network side device. When decoding, the target position of the unavailable time-frequency resource indicated in the target rate matching spectrum is not decoded, thereby effectively reducing the LNR boundary interference by sacrificing a small amount of time-frequency resources.

[0056] In one or more embodiments of the present disclosure, the terminal may pre-store the serial numbers of a plurality of different rate matching spectra, the CRS interference information may include a location interfered by the CRS or the CRS interference information indicates that the terminal has no CRS interference, and the target locations of the unavailable time-frequency resources indicated in different rate matching spectra are different, such as Figure 3 As shown, the information of determining the target rate matching spectrum according to the CRS interference information may include:

[0057] S2062: When the CRS interference information includes a position interfered by the CRS, according to a preset correspondence between the position of the CRS interference and the rate matching spectrum, determine the number of the rate matching spectrum corresponding to the position of the CRS interference in the multiple different rate matching spectrums as the number of the target rate matching spectrum;

[0058] The terminal may pre-store the correspondence between the position of CRS interference and the rate matching map, which may be expressed as the correspondence between the position of CRS interference and the number of the rate matching map. Based on this, the number of the target rate matching map may be determined according to the correspondence.

[0059] It should be noted that the terminal may store the numbers of multiple different rate matching maps, or may directly store multiple different rate matching maps. If the terminal only stores the numbers of multiple different rate matching maps, after determining the target rate matching map, the terminal may send the number of the target rate matching map to the network side device to request to obtain the target rate matching map from the network side device; if the terminal stores multiple different rate matching maps, the terminal may directly decode the signal from the network side device using the target rate matching map based on the number of the target rate matching map.

[0060] S2064: When the CRS interference information indicates that the terminal has no CRS interference, determine, according to the CRS interference information, that the spectrum number of the target rate matching spectrum is 0 or empty.

[0061] When the target rate matching map is numbered 0 or empty, the terminal may determine not to use any rate matching map and directly perform normal business processing. Alternatively, the terminal may send the number 0 or empty to the network side device. After receiving the number, the network side device does not send any rate matching map to the terminal. Without receiving feedback from the network side device, the terminal does not use any rate matching map and performs normal business processing.

[0062] exist Figure 3 In the illustrated embodiment, the target rate matching spectrum is determined based on the location affected by CRS interference included in the CRS interference information, or the information in the CRS interference information indicating that the terminal is not interfered with by CRS, so that it can be ensured that the unavailable time-frequency resources specified in the target rate matching spectrum correspond to the CRS interference situation, thereby effectively shielding LNR neighboring cell interference by sacrificing a small amount of time-frequency resources.

[0063] In one or more embodiments of the present disclosure, the rate matching spectrum may include symbols and subcarriers corresponding to the symbols;

[0064] In the rate matching spectrum, starting from the position of the CRS interference, the symbols at the preset positions of the target subcarriers at every preset number of subcarriers are indicated as unavailable;

[0065] Among them, taking 2 as an example of the preset number, the third subcarrier between every two subcarriers can be the target subcarrier, and only the time-frequency resources indicated as unavailable are configured in the target subcarrier.

[0066] In one example, the vshift field is used to record the position of the CRS. Figures 4A to 4CThe diagram shows the rate matching spectrum of the time-frequency resources corresponding to the CRS at the positions of vshift=0, 1, and 2 on symbols 0, 1, 4, 7, 8, and 11, in which the gray grids represent the time-frequency resources that are removed, and the white grids represent the time-frequency resources that are not removed. The time-frequency resources that are removed are indicated as unavailable time-frequency resources, and the time-frequency resources that are not removed are indicated as available time-frequency resources. Among them, symbols 0, 1, 4, 7, 8, and 11 (i.e., an example of the above-mentioned preset positions) are shown.

[0067] Alternatively, in the rate matching spectrum, symbols at corresponding preset positions of all subcarriers are indicated as unavailable. Figure 4D The figure shows the time-frequency resources corresponding to the entire symbol 20M bandwidth when symbols 0, 1, 4, 7, 8, and 11 are removed. Symbols 0, 1, 4, 7, 8, and 11 are an example of the above-mentioned preset positions.

[0068] The granularity of the unavailable time-frequency resources indicated in the rate matching map can be adaptively switched between the RE level and the symbol level. For example, RE level rate matching is used when the interference is weak, and symbol level rate matching is used when the interference is strong. This can greatly improve the spectrum efficiency while solving the LNR boundary interference problem. The terminal can sacrifice a small amount of time-frequency resources (for example, 7%-20%) to avoid CRS interference. Figure 1 Taking the networking mode shown as an example, the scheduling performance of the 40M NR network edge can be significantly better than that of the 20MNR or 20M LTE network.

[0069] In one or more embodiments of the present disclosure, Figure 5 As shown, the boundary interference elimination method may also include:

[0070] Step S502: after determining information of a target rate matching map according to the CRS interference information, determining whether the target rate matching map is consistent with a rate matching map currently used by the terminal;

[0071] For example, whether the target rate matching map is consistent with the rate matching map currently used by the terminal may be determined by comparing the number of the target rate matching map with the number of the rate matching map currently used by the terminal.

[0072] Step S504: In response to the target rate matching map being inconsistent with the rate matching map currently used by the terminal, requesting the network side device to obtain the target rate matching map;

[0073] If the target rate matching map is consistent with the rate matching map currently used by the terminal, the terminal does not need to request the network side device to obtain the target rate matching map, for example, the terminal does not need to send the target rate matching map number to the network side device, thereby reducing the number of interactions between the terminal and the network side device.

[0074] In step S504, if the target rate matching map is inconsistent with the rate matching map currently used by the terminal, the terminal may send the number of the target rate matching map to the network side device through UCI (Uplink Control Information) or PUSCH (Physical Uplink Shared Channel) to request to obtain the target rate matching map.

[0075] Step S506: Receive the target rate matching map sent by the network side device.

[0076] After receiving a request from the terminal to obtain a target rate matching map, the network side device may configure the target rate matching map to the terminal through DCI (Downlink Control Information). Optionally, the network side device may store multiple different rate matching maps, and after receiving the number of the target rate matching map from the terminal, the target rate matching map may be sent to the terminal according to the number. Alternatively, when the received number is 0 or empty, no rate matching map is sent to the terminal.

[0077] In one or more embodiments of the present disclosure, the terminal may store serial numbers of different rate matching maps in advance, and requesting the network side device to obtain the target rate matching map may include:

[0078] The target rate matching map number is sent to the network side device. For example, the terminal can report a 3-bit map number field avoidCRSpattern to the network side device through UCI. avoidCRSpattern=0 means that there is no CRS interference from neighboring LTE, and the network side device may not send the rate matching map to the terminal; the four cases of avoidCRSpattern=1-4 correspond to the following respectively: Figures 4A-4D Four spectra. If the surrounding neighboring areas are interfered with by more LNR interference areas, the field pattern = 4 can be reported to the network side device. The corresponding target rate matching spectrum is as follows Figure 4DAs shown. For example, if the terminal obtains at least two of the following situations in which vshift=0, 1, and 2 are included in the CRS interference position, it can be determined that more LNR interference areas in the surrounding neighboring areas are interfered with. Accordingly, it is determined that the number of the target rate matching spectrum currently required by the terminal is pattern=4. Among them, avoidCRSpattern=0, and 0, 1, 2, 3, and 4 in avoidCRSpattern=1-4 represent the numbers of the rate matching spectrum, respectively. Among them, the number 0 represents no rate matching spectrum. The terminal sends the number 0 to the network side device to indicate that no network rate matching spectrum is required. When the base station receives the number 0, it does not send any rate matching spectrum to the terminal.

[0079] In one or more embodiments of the present disclosure, the preset condition may be that the SINR is lower than a first threshold or higher than a second threshold, wherein the first threshold is greater than the second threshold. Optionally, when the rate matching spectrum currently used by the terminal is different, the corresponding preset condition is also different. For example, if the terminal is not currently using any rate matching spectrum, the preset condition may be that the SINR is lower than 12dB (an example of the first threshold), and if the terminal is currently using a rate matching spectrum, the preset condition may be higher than the second threshold, and the second threshold may be set to be not less than 6dB, for example.

[0080] Figure 6 is a flow chart of a boundary interference elimination method according to one or more embodiments of the present disclosure. The method may be executed by a network side device. The network side device may be provided as a base station, such as Figure 6 As shown, the method includes:

[0081] S602: Obtain information of a target rate matching map from a terminal;

[0082] The target rate matching map may be a resource map, which may include information about symbols and subcarriers corresponding to the symbols, wherein the time-frequency resources at each position may be indicated as available or unavailable.

[0083] Optionally, the information of the target rate matching map from the terminal may include, for example, the serial number of the target rate matching map from the terminal.

[0084] S604: Sending the target rate matching map to the terminal according to information of the target rate matching map, wherein the target position of unused time-frequency resources is indicated in the target rate matching map;

[0085] The information of the target rate matching map still takes the map number as an example. The network side device may pre-store multiple different rate matching maps. After receiving the target rate matching map number from the terminal, the target rate matching map may be sent to the terminal according to the number. Alternatively, when the received number is 0 or empty, no rate matching map is sent to the terminal.

[0086] Optionally, the target position of the unused time-frequency resources indicated in the target rate matching map may correspond to the CRS position detected on the terminal side. Based on this, the LNR boundary interference may be reduced by sacrificing a small amount of time-frequency resources.

[0087] Step S606: Send data to the terminal according to the target rate matching map, wherein no data is sent at the target location.

[0088] Optionally, the network side device may send data on time-frequency resources indicated as available in the spectrum according to the target rate matching spectrum, and not send data on time-frequency resources indicated as unavailable in the spectrum.

[0089] The boundary interference elimination method of one or more embodiments of the present disclosure receives information of a target rate matching spectrum sent by a terminal, sends the target rate matching spectrum to the terminal according to the information, and sends data to the terminal according to the target rate matching spectrum, and does not send data at a time-frequency resource location indicated as unavailable in the target rate matching spectrum, thereby effectively reducing LNR boundary interference.

[0090] In one or more embodiments of the present disclosure, the information of the target rate matching map may include the number of the target rate matching map. Optionally, the correspondence between each rate matching map and the number may be pre-stored in the network side device. After the network side device obtains the number of the target rate matching map from the terminal, the target rate matching map may be obtained to send the map to the terminal. In addition, the number 0 or the number is empty corresponds to the situation where the rate matching map does not exist. When the network side device receives the information of the number 0 or the number is empty, it does not send any rate matching map to the terminal.

[0091] In one or more embodiments of the present disclosure, a plurality of different rate matching spectra are pre-stored in the network side device, and different target locations of unavailable time-frequency resources indicated in different rate matching spectra are different. For example, different rate matching spectra correspond to different locations of CRS interference, or a certain rate matching spectra (such as Figure 4D The rate matching spectrum shown in corresponds to the situation where CRS interference exists in multiple areas. Therefore, the corresponding rate matching spectrum can be matched according to the actual CRS interference situation of the terminal, thereby improving the applicability of the boundary interference elimination method of the embodiment of the present disclosure.

[0092] In one or more embodiments of the present disclosure, the rate matching spectrum may include symbols and subcarriers corresponding to the symbols;

[0093] In the rate matching spectrum, starting from the position of the CRS interference, the symbols at the preset positions of the target subcarriers at every preset number of subcarriers are indicated as unavailable;

[0094] Alternatively, in the rate matching map, symbols at corresponding preset positions of all subcarriers are indicated as unavailable.

[0095] Among them, the preset position can be set in advance according to the position where CRS interference often occurs, so that the rate matching spectrum can be better applied to various CRS interference situations.

[0096] Optionally, for a position of time-frequency resources indicated as unavailable in the rate matching spectrum, the network-side device does not send data at that position, and the terminal does not perform decoding at that position.

[0097] In one or more embodiments of the present disclosure, the rate matching spectrum used by the terminal may also be determined by the network side device according to the SINR, such as Figure 7 As shown, the method may also include:

[0098] Step S702: receiving a signal to interference plus noise ratio SINR reported by the terminal;

[0099] Step S704: In response to the SINR being greater than a third threshold, not sending a rate matching map to the terminal;

[0100] When the SINR of the terminal is greater than the third threshold, it can be determined that there are fewer locations on the terminal side that are interfered by CRS. At this time, the terminal does not need to use any rate matching spectrum, so the network side device does not need to send any rate matching spectrum to the terminal.

[0101] Step S706: In response to the SINR being less than a fourth threshold, sending a first rate matching spectrum to the terminal, the first rate matching spectrum including symbols and subcarriers corresponding to the symbols, in which the symbols at corresponding preset positions of all subcarriers are indicated as unavailable, wherein the third threshold is greater than the fourth threshold.

[0102] When the SINR of the terminal is less than the fourth threshold, it can be determined that the terminal side is more affected by CRS interference, and the terminal needs to sacrifice certain time-frequency resources to avoid CRS interference. On this basis, the network side device can send the rate matching map with more time-frequency resources indicated as unavailable in its stored rate matching map to the terminal. Figures 4A-4D The four rate matching spectra shown are: Figure 4D In the rate matching map shown in , the time-frequency resources indicated as unavailable are the most numerous.

[0103] Figure 8 is a flow chart of a method for eliminating boundary interference according to one or more embodiments of the present disclosure. Figure 8 As shown, the method may include the following processing:

[0104] Step S802: The NR terminal (an example of the above terminal) accesses the 40M NR cell and initiates a service without performing rate matching, that is, without matching the rate matching spectrum, and monitors the SINR value in real time.

[0105] Step S804: Determine the SINR size. If the SINR is lower than 12 dB (an example of the first threshold), execute step S806. Otherwise, execute back to step S802.

[0106] Step S806: Start the terminal CRS-IC self-check. The self-check result can be reported to the base station (an example of the above-mentioned network side device) through the UCI or PUSCH 3-bit field avoidCRSpattern. If pattern = 0, execute step S808; if pattern = 1-3, execute step S810; if pattern = 4, execute step S812;

[0107] Step S808: The terminal does not need a rate matching spectrum, continues to process services, and detects the SINR size.

[0108] Step S810: The base station switches to spectrum 1, 2 or 3 accordingly, and configures spectrum 1, 2 or 3 to the terminal through DCI.

[0109] Step S812: the base station switches to profile 4 and configures profile 4 to the terminal through DCI;

[0110] If the base station switches to spectrum 4, it continues to monitor the SINR size;

[0111] Step S814: Determine whether the SINR is not less than 6dB. If the SINR is higher than 6dB, execute step S816. If the SINR is not greater than 6dB, execute step S818.

[0112] Step S816: The terminal starts self-test, and the 3-bit field of the self-test result is reported to the base station through UCI. If the result is pattern=4, step S818 is executed;

[0113] Step S818: Maintaining spectrum 4 and continuing to monitor SINR;

[0114] If the terminal self-check result is pattern = 1, 2 or 3 in step S806, and the base station is notified to switch to pattern 1, 2 or 3, step S820 is executed;

[0115] Step S820: monitor the SINR of the terminal, if the SINR is ≥ 15dB, execute step S822, if the SINR is less than 15dB, execute step S824;

[0116] Step S822: the base station does not send a rate matching map, and the terminal directly switches back to the pattern=0 mode, and the terminal does not need to self-check;

[0117] Step S824: Determine whether the SINR is less than 4 dB, if so, execute step S826, if not, execute step S828;

[0118] Step S826: Switch back to profile 4 and configure it to the terminal through DCI, and the terminal does not need to self-check;

[0119] Step S828: Keep pattern 1, 2 or 3. Periodically perform CRS self-check to detect CRS interference deviation and report the value of Pattern in time. The pattern will generally switch between 1-3, and there is a small probability of switching to 0 or 4.

[0120] It should be noted that the above judgment thresholds 4, 6, 12, and 15 are all empirical values ​​and can be optimized and changed according to the actual situation of the existing network. By optimizing the four thresholds, the network can reduce the ping-pong effect of spectrum switching at the LNR boundary and improve the average rate.

[0121] When the boundary interference elimination method of the embodiment of the present disclosure is used to combat interference at the boundary of an outdoor 40M NR network and a 20M LTE frequency point, after the method is applied to the 40M NR network, the NR terminal at the junction of the cell edge and the 20M LTE will reduce the interference caused by the LTE CRS when scheduling a 40M large bandwidth, thereby achieving the effect of improving the average rate of the NR terminal. Compared with the frequency selection scheduling algorithm, the spectrum utilization rate is improved. And experiments have shown that when the 40M NR is adjacent to a 20M LTE frequency point, the boundary interference elimination method of one or more embodiments of the present disclosure can be applied without setting an isolation zone.
