[0002] With the continuous development of communication technology, people have increasingly higher requirements for communication quality.
[0003] Subband non-overlapping full duplex (SBFD) divides a spectrum into several subbands, allowing uplink and downlink resources to coexist in the same time slot. This enables separate data transmission and reception, achieving full-duplex operation at the base station. Flexible scheduling across subbands can meet the high bandwidth and low latency concurrency requirements of industry applications. However, if different base stations use different uplink and downlink time slot structures, cross-slot interference can occur. Due to the high transmit power of base stations, the downlink interference generated by their downlink transmissions is relatively high, which can severely degrade the uplink performance of other base stations, or even prevent uplink communication altogether. Therefore, reducing communication interference between base stations is a pressing issue. Summary of the Invention

[0047] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.
[0048] The interference coordination method provided in this application embodiment can be applied to, for example... Figure 1 In the application environment shown, the interfering base station 104 and the interfered base station 106 are communicatively connected to the interference coordinator 102. The interference coordinator 102 can monitor and adjust the transmission power and frequency band of base stations within a preset area. The interfering base station 104 transmits a reference signal, and the interfered base station 106 receives the reference signal. In this embodiment, the interference coordinator 102 can obtain the reference signal received power of the interfered base station 106 and the reference signal transmitted power of the interfering base station 104. Based on the transmission power of the interfering base station 104 and the received power of the interfered base station 106, the interference situation of the interfering base station 104 on the interfered base station 106 is determined. Based on the interference situation, an interference coordination strategy for the interfering base station 104 on the interfered base station 102 is determined, thereby reducing the interference of the interfering base station on the interfered base station.
[0049] It should be noted that the reference signal is a known signal. Different harassing base stations transmit different reference signals. The interference coordinator can obtain the transmission power of the reference signal transmitted by the harassing base station, as well as the identifier of the harassing base station corresponding to the transmission power. The interference coordinator can also obtain the received power of the reference signal of the harassed base station. Different harassing base stations can transmit reference signals at the same time or at different times.
[0050] In one embodiment, such as Figure 2 As shown, an interference coordination method is provided, which can be applied to... Figure 1 The following steps are used as an example of the interference coordinator in the process, including steps 202 to 206.
[0051] Step 202: Obtain the reference signal transmission power of the disturbed base station and the reference signal reception power of the disturbing base station.
[0052] In this embodiment, the spectral sub-bands corresponding to the scrambling base station and the scrambling base station are the same within the same time slot. That is, within the same time slot, the scrambling base station transmits uplink signals via the uplink sub-band and downlink signals via the downlink sub-band; correspondingly, the scrambling base station also transmits uplink signals via the uplink sub-band and downlink signals via the downlink sub-band. The sub-bands of the signals transmitted by the scrambling and scrambling base stations will only change in the next time slot. For example, the sub-band that transmitted uplink signals in the previous time slot will transmit downlink signals in the current time slot, and vice versa. It should be noted that in different time slots, the scrambling base station may become the scrambling base station, and vice versa; that is, the scrambling and scrambling base stations in this embodiment are not fixed. This embodiment describes the interference base station and the interference base station in the same time slot. In the same time slot, the downlink subband of the interference base station transmits downlink signals, and the uplink subband of the interference base station transmits uplink signals. If the downlink subband of the interference base station and the uplink subband of the interference base station are in the same frequency band or adjacent frequency bands, then the downlink signal of the interference base station will interfere with the uplink signal of the interference base station.
[0053] Optionally, the disrupted base station can be any base station. In practical applications, the disrupted base station is typically the base station corresponding to the uplink subband transmitting uplink signals that needs to be protected. The disrupting base station can be any base station other than the disrupted base station. In practical applications, the disrupting base station is a neighboring base station near the disrupted base station. The downlink subband of the disrupting base station may interfere with the uplink subband of the disrupted base station. There can be multiple disrupting base stations, that is, a preset number of neighboring base stations. The specific number can be set according to the actual situation and is not limited here.
[0054] A reference signal (RS) is a known signal provided by the transmitter to the receiver for channel estimation or channel sounding. In this embodiment, the scrambling base station transmits a reference signal, and the scrambling base station receives the reference signal. The interference coordinator can obtain the transmission power of the reference signal transmitted by the scrambling base station and the reception power of the reference signal received by the scrambling base station.
[0055] Step 204: Determine the interference situation of the interfering base station on the affected base station based on the transmit power and receive power.
[0056] The interference coordinator can determine the interference situation of the interfering base station on the affected base station based on the acquired transmit power of the reference signal transmitted by the interfering base station and the receive power of the reference signal received by the affected base station. In this embodiment, interference can refer to the interference caused by downlink communication of adjacent base stations to uplink communication of the affected base station in the same time slot.
[0057] In this embodiment, a disturbed base station may have one or more neighboring base stations. For example, based on the reference signal received power of the disturbed base station and the reference signal transmitted power of the disturbing base station A, the interference situation I of the disturbing base station A on the disturbed base station can be determined. A Based on the reference signal received power of the disturbed base station and the reference signal transmitted power of the disturbing base station B, the interference situation of the disturbing base station B on the disturbed base station can be determined. B The interference from other scrambling base stations to the scrambling base station follows the same pattern. The number of scrambling base stations is the same as the number of received power levels, and the number of interference cases caused by scrambling base stations to the scrambling base station is also the same.
[0058] Optionally, the interference of the interfering base station on the affected base station can be assessed based on the path loss between the interfering and affected base stations. The path loss between the interfering and affected base stations can be determined based on the transmit and receive power, and the interference of the interfering base station on the affected base station can be assessed accordingly. Path loss, also known as propagation loss, refers to the loss caused by the propagation of radio waves in space. It is caused by the radiation and diffusion of transmit power and the propagation characteristics of the channel, reflecting the variation in the average received signal power over a macroscopic range. The greater the path loss, the less interference the interfering base station causes to the affected base station.
[0059] Optionally, the interference of the interfering base station on the affected base station can be determined based on the spatial distance between the interfering base station and the affected base station, as well as the obstacles along the transmission path of the reference signal. For example, the greater the spatial distance between the interfering base station and the affected base station, and the more obstacles along the signal transmission path, the less interference the interfering base station will cause to the affected base station.
[0060] Step 206: Determine the interference coordination strategy between the interfering base station and the affected base station based on the interference situation.
[0061] Based on the interference situation of the disrupting base station on the disrupted base station, interference coordination strategies can be determined. To mitigate the interference, measures such as reducing the transmission power of the disrupting base station and adjusting the tower amplifier gain can be implemented.
[0062] Optionally, the transmission power of the interfering base station can be adjusted according to the interference situation. The greater the interference, the greater the power reduction required by the interfering base station; conversely, the less interference, the less power reduction is required.
[0063] Optionally, depending on the interference situation, the interference-restricted area in the subband corresponding to the interfering base station and / or the interference-restricted area in the subband of the interfered base station can be adjusted. The interference-restricted area and the interference-restricted area are subband areas that are not used or are used with the lowest priority in the current time slot. When a restricted area is set in a subband, the entire subband does not transmit signals during operation; only the areas within that subband other than the restricted area can transmit signals. Depending on the interference situation, the interference-restricted area in the subband corresponding to the interfering base station or the interference-restricted area in the subband of the interfered base station can be adjusted, or both can be adjusted simultaneously.
[0064] Optionally, the transmit power of the interfering base station and the interference-restricted area in the corresponding subband of the interfering base station, and / or the interference-restricted area in the subband of the interfering base station can be adjusted according to the interference situation. Simultaneous adjustments to the transmit power of the interfering base station and the interference-restricted area and / or the interference-restricted area can reduce the interference from the interfering base station to the interfering base station.
[0065] The aforementioned interference coordination method obtains the reference signal transmission power of the disturbed base station and the reference signal reception power of the disturbing base station. Based on the transmission and reception power, it determines the interference situation of the disturbing base station on the disturbed base station. Based on the interference situation, it determines the interference coordination strategy of the disturbing base station on the disturbed base station. While meeting the uplink and downlink transmission needs of different base stations, it can greatly reduce the interference of the disturbing base station on the disturbed base station. The dynamic adjustment for different time slots can improve the utilization efficiency of the base station spectrum.
[0066] In one embodiment, determining the interference situation of the interfering base station to the interfering base station based on the transmit power and receive power includes: determining the path loss value between the interfering base station and the interfering base station based on the transmit power and receive power; wherein the path loss value is used to characterize the interference situation.
[0067] In this embodiment, the path loss value between the disrupting and disrupted base stations can be determined based on the reference signal transmit power of the disrupted base station and the reference signal receive power of the disrupting base station. The path loss value can characterize the interference between the disrupting and disrupted base stations. The smaller the path loss value, the greater the interference from the disrupting base station to the disrupted base station; conversely, the larger the path loss value, the smaller the interference from the disrupting base station to the disrupted base station.
[0068] Optionally, the difference between the transmit power and the receive power can be used as the path loss value between the interfering base station and the interfered base station. Generally, due to losses on the transmission path, the smaller the difference between the transmit power and the receive power, the smaller the path loss value between the interfering base station and the interfered base station, and the greater the interference from the interfering base station to the interfered base station.
[0069] The aforementioned interference coordination method determines the path loss value between the interfering base station and the affected base station by using the transmit power and receive power. The path loss value characterizes the interference situation of the interfering base station on the affected base station, which can realize the quantitative characterization of the interference situation and accurately measure the interference situation of the interfering base station on the affected base station.
[0070] In some embodiments, determining the path loss value between the harassing base station and the harassed base station based on the transmit power and the receive power includes: using the difference between the transmit power and the receive power as the path loss value between the harassing base station and the harassed base station.
[0071] In this embodiment, the difference between the transmit power and the receive power can be directly used as the path loss value between the interfering base station and the interfered base station. Optionally, the product of the difference between the transmit power and the receive power and a constant, or the quotient of the difference with a constant, can also be used to characterize the interference between the interfering base station and the interfered base station. It is understood that, while retaining the difference between the transmit power and the receive power, appropriate modifications are allowed to make the path loss value more accurate in specific application scenarios. Even after modification, it should still fall within the protection scope of this application.
[0072] In one embodiment, determining an interference coordination strategy between the interfering base station and the affected base station based on the interference situation includes: obtaining the interference-restricted area of the communication subband corresponding to the interfering base station and the interference-restricted area of the communication subband corresponding to the affected base station; and adjusting at least one of the width of the interference-restricted area or the width of the interference-restricted area based on the interference situation.
[0073] In this embodiment, a interference-restricted region is set in the communication subband corresponding to the interfering base station, and a interference-restricted region is set in the communication subband corresponding to the disturbed base station. Without considering overlapping subbands, there is cross-interference between uplink and downlink communication signals between adjacent base stations. In practical applications, the downlink subband of the interfering base station mainly interferes with the uplink subband of the disturbed base station, which can be avoided by setting up spatial isolation between base stations, subband bandpass filters, etc.
[0074] In one example, such as Figure 3 The restricted area configuration shown for the interfering and affected base stations involves setting an interference-restricted area 312 in the downlink subband 310 of the interfering base station and an interference-restricted area 306 in the uplink subband 308 of the affected base station. Furthermore, to reduce self-interference between the uplink and downlink subbands of SBFD communication within the same base station, self-interference isolation bands such as transceiver antenna spatial isolation and subband isolation can be used for avoidance. Therefore, for example... Figure 3 As shown, a first self-interference isolation band 314 is set between the uplink subband 316 and the downlink subband 310 of the interfering base station; a second self-interference isolation band 304 is set between the uplink subband 308 and the downlink subband 302 of the interfered base station.
[0075] The interference-restricted region of the communication subband corresponding to the interfering base station and the interference-restricted region of the communication subband corresponding to the interfered base station are obtained. Based on the interference situation, at least one of the widths of the interference-restricted region and the interference-restricted region is adjusted. In this embodiment, based on the interference situation, either the width of the interference-restricted region or the width of the interference-restricted region can be adjusted. Optionally, either the width of the interference-restricted region or the width of the interference-restricted region can be adjusted, but the adjusted width of either the interference-restricted region or the interference-restricted region may be zero.
[0076] Optionally, the width of either the interference-restricted area or the width of the affected area can be adjusted according to the magnitude of the interference. When the interference from the corresponding interfering base station is significant, the width of the interference-restricted area of the interfering base station needs to be larger; that is, the width of the interference-restricted area of the interfering base station needs to be adjusted to a wider state to avoid interfering with the affected base station. Simultaneously, the width of the interference-restricted area of the affected base station can also be adjusted to a wider state to avoid being interfered with by the interfering base station. For example, the width of either the interference-restricted area or the width of the affected area can be adjusted according to the magnitude of the path loss. When the path loss corresponding to the interfering base station is small, the width of the interference-restricted area of the interfering base station needs to be adjusted to a wider state to avoid interfering with the affected base station. Simultaneously, the width of the interference-restricted area of the affected base station can also be adjusted to a wider state to avoid being interfered with by the interfering base station.
[0077] In some embodiments, the process for adjusting the width of the restricted area is as follows: Figure 4 As shown, depending on the interference situation, at least one of the width of the interference-restricted area or the width of the interference-restricted area is adjusted, including steps 402 to 406.
[0078] Step 402: Obtain the adjustable interference base station corresponding to the interference level being greater than the preset interference level.
[0079] Among the interfering base stations participating in interference coordination, those with interference levels greater than a preset interference level are selected as adjustable interfering base stations. The preset interference level can be a preset path loss value, which can be set according to specific circumstances and is not limited here. Correspondingly, interfering base stations with path loss values less than the preset loss value can be selected as adjustable interfering base stations.
[0080] Step 404: Arrange the adjustable interference base stations in descending order of interference level to obtain the sorting result.
[0081] In this embodiment, the adjustable scrambling base stations can be arranged in descending order of their interference levels to obtain the corresponding sorting result. Optionally, they can be arranged in ascending order of their path loss values to obtain the corresponding sorting result. The sorting result can be represented in the form of a list or a graph; an example arrangement is as follows: Figure 5 As shown, the scrambling base stations 1 to 6 corresponding to path loss values less than the preset loss value are obtained as adjustable scrambling base stations. They are arranged in ascending order of path loss value. The sorting result of scrambling base stations 1 to 6 is: scrambling base station 1, scrambling base station 2, scrambling base station 3, scrambling base station 4, scrambling base station 5, scrambling base station 6.
[0082] Step 406: Adjust at least one of the widths of the scrambling restricted region or the scrambling restricted region according to the sorting results.
[0083] The interference coordinator can adjust at least one of the widths of the interference-restricted area or the interference-restricted area based on the sorting results. For the interfering base station with a higher interference level, the width of either the interference-restricted area or the interference-restricted area should be increased. Optionally, based on the sorting results, for the interfering base station with a lower path loss value, the width of either the interference-restricted area or the interference-restricted area should be increased.
[0084] In one example, based on the sorting results of the path loss values, if the path loss value is less than P1, the width of the corresponding scrambling restricted area is adjusted to B1; if the path loss value is greater than P1 and less than P2, the width of the corresponding scrambling restricted area is adjusted to B2, where B1 is greater than B2.
[0085] The interference coordination method in the above embodiments obtains adjustable scrambling base stations with interference levels greater than a preset interference level, arranges the adjustable scrambling base stations in descending order of interference level to obtain a sorting result, and adjusts at least one of the width of the scrambling restricted area or the width of the scrambling restricted area according to the sorting result. This enables rapid adjustment of the scrambling restricted area of the scrambling base station and the scrambling restricted area of the scrambling base station, thereby improving the efficiency of interference coordination and spectrum utilization efficiency.
[0086] In one embodiment, determining an interference coordination strategy between the interfering base station and the affected base station based on the interference situation includes adjusting the transmission power of the interfering base station based on the interference situation.
[0087] In this embodiment, the interference coordinator can adjust the transmission power of the interfering base station according to the magnitude of the interference, thereby reducing the degree of interference from the interfering base station to the affected base station. For example, the adjustable interfering base stations are arranged in descending order of interference level to obtain a first ranking result; the transmission power of the interfering base stations is adjusted accordingly based on the first ranking result. The greater the interference, the greater the reduction in the transmission power of the interfering base station; conversely, the smaller the interference, the smaller the reduction in the transmission power of the interfering base station.
[0088] Optionally, the interference coordinator adjusts the transmit power of the interfering base station based on the path loss value. For example, the adjustable interfering base stations are arranged in descending order of their path loss values to obtain a second sorting result; the transmit power of the interfering base stations is adjusted accordingly based on the second sorting result. The smaller the path loss value, the greater the reduction in the transmit power of the interfering base station; conversely, the larger the path loss value, the smaller the reduction in the transmit power of the interfering base station.
[0089] This embodiment adjusts the transmission power of the interfering base station according to the interference situation, which can greatly reduce the interference of the interfering base station to the affected base station, thereby improving spectrum utilization efficiency.
[0090] In one embodiment, such as Figure 6 As shown, the interference coordination method includes steps 602 to 610.
[0091] Step 602: Obtain the reference signal received power of the disturbed base station in the same time slot, and the reference signal transmitted power of a preset number of disturbing base stations.
[0092] Step 604: Calculate the path loss value between the interfering base station and the interfered base station based on the transmission power and the preset number of received power.
[0093] Step 606: Obtain the scrambling base stations whose path loss values are less than the preset loss value as optional scrambling base stations, and arrange the optional base stations in ascending order according to their path loss values to obtain the sorting result.
[0094] Step 608: Based on the sorting results, adjust at least one of the widths of the harassment-restricted region or the harassment-restricted region.
[0095] Step 610: Adjust the transmission power of the interfering base station according to the sorting results.
[0096] The interference coordination method in the above embodiments adjusts at least one of the width of the interference-restricted area or the width of the interference-restricted area by adjusting the path loss value between the interfering base station and the interference-restricted base station, and adjusts the transmission power of the interfering base station. While meeting the uplink and downlink transmission requirements of different base stations, it can reduce the interference of the interfering base station to the interference-restricted base station to a large extent, thereby improving the spectrum utilization efficiency in SBFD communication.
