Description

[0002] In the early stage of 5G (5th Generation Mobile Communication Technology) NR (New Radio) network deployment, especially the early stage of large-bandwidth 5GNR network deployment, since the existing network frequency clearance work has not been completed, it is possible that part of the bandwidth of the large-bandwidth 5G NR network overlaps with the bandwidth of its adjacent small-bandwidth LTE network. In this scenario of partial bandwidth overlap, due to factors such as the LTE network CRS (Cell Reference Signal) transmission mechanism and the large-bandwidth NR MCS (Modulation Coding Scheme) selection mechanism, the large-bandwidth 5G NR network will be subject to strong interference from the small-bandwidth LTE network, resulting in serious deterioration of the performance of the large-bandwidth 5G NR network, and its performance is even lower than that of the small-bandwidth 5G NR network.

[0040] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present disclosure, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0042] Figure 1 A schematic diagram showing a large bandwidth 5G NR network being interfered by an adjacent small bandwidth LTE network with partial bandwidth overlap scheduling. Figure 1 As shown in the figure, the frequency band of the large-bandwidth 5G NR network is F1+F2, and the frequency band of the small-bandwidth LTE network is F1, and its F1 partial bandwidth overlaps with the adjacent small-bandwidth LTE network bandwidth. In this scenario of partial bandwidth overlap, based on the Dynamic Spectrum Sharing (DSS) technology that enables 5G NR and LTE to coexist, due to factors such as the LTE network CRS (Cell Reference Signal) transmission mechanism and the large-bandwidth NR MCS (Modulation Coding Scheme) selection mechanism, the large-bandwidth 5G NR network will be strongly interfered by the small-bandwidth LTE network.

[0043] Figure 2 is based on Figure 1A schematic diagram of a scheme for reducing network interference based on frequency selection scheduling in the related art is shown. In the related art, the interference of small-bandwidth LTE to the overlapping bandwidth of large-bandwidth 5G NR network is passively avoided by frequency selection scheduling. Obviously, the utilization rate of large-bandwidth NR frequency band is greatly reduced under this scheme.

[0044] Therefore, the present disclosure provides a signal processing method, which obtains a target overlapping frequency band in which a first frequency band of a first network having a bandwidth greater than a second frequency band overlaps with a second frequency band of a second network, obtains a first target cell covered by the first network and a second target cell covered by the second network and including the same geographical area as the first target cell, and increases the signal transmission power of the first network in the target overlapping frequency band in the first target cell, and / or reduces the signal transmission power of the second network in the target overlapping frequency band in the second target cell, so as to increase the proportion of the signal transmission power of the first network in the target overlapping frequency band in the first target cell, and / or reduces the proportion of the signal transmission power of the second network in the target overlapping frequency band in the second target cell to the signal transmission power of the first network in the target overlapping frequency band in the first target cell, thereby achieving, without reducing the frequency band utilization rate of the first network with large bandwidth, improving the signal-to-noise ratio of the first network, increasing the proportion of useful signals of the large bandwidth network in the bandwidth overlapping network, and reducing interference of the small bandwidth network.

[0045] Figure 3 FIG. 1 is a flow chart of a signal processing method according to an exemplary embodiment. Figure 3 The method shown can be applied, for example, to a network device of a first network with a large bandwidth.

[0046] refer to Figure 3 , the method 30 provided in the embodiment of the present disclosure may include the following steps.

[0047] In step S302, a target overlapping frequency band of the first network and the second network is obtained, where the target overlapping frequency band is the overlapping portion of the first frequency band and the second frequency band. Data is transmitted in the first network via the first frequency band and in the second network via the second frequency band. The bandwidth of the first frequency band is greater than the bandwidth of the second frequency band.

[0048] In some embodiments, the first network may be a fifth generation mobile communication technology (5G) new radio (NR) network, and the second network may be a long term evolution (LTE) network.

[0049] In some embodiments, the bandwidth of the overlapping portion of the large-bandwidth NR network and the small-bandwidth LTE network can be identified based on the network frequency band defined in the network planning, or through network frequency band measurement and other methods.

[0050] In some embodiments, for example, the target overlapping frequency band is the second frequency band, such as the overlapping portion of the large bandwidth NR network and the small bandwidth LTE network is the entire frequency band of the small bandwidth LTE network.

[0051] In step S304, a first target cell covered by the first network and a second target cell covered by the second network are obtained, and the first target cell and the second target cell include the same geographical area.

[0052] In some embodiments, the first target cell and the second target cell can be one or more cells. The first target cell and the second target cell can be adjacent cells, and the adjacent cells are cells adjacent to the area covered by the network signal, and the adjacent cells include the same geographical area. For example, the area covered by the large-bandwidth NR network is within the second ring of a city, and the area from the second ring to the fourth ring is covered by a small-bandwidth LTE network. Then, at the junction of the second ring and the third ring, the cell at the junction within the second ring is the first target cell, and the cell at the junction within the third ring is the second target cell. The junction of the second ring and the third ring is the same geographical area in the first target cell and the second target cell.

[0053] In other embodiments, the first target cell and the second target cell may also be non-adjacent cells, that is, the first target cell and the second target cell are two non-adjacent cells in network planning, but the two cells include the same geographical area and are also applicable to the method provided in the embodiments of the present disclosure.

[0054] In some embodiments, the first target cell and the second target cell may be identified according to the network coverage cells set in the network planning, or through system information exchange, etc. For example, if the first target cell and the second target cell are both multiple cells, a first target cell set and a second target cell set are identified.

[0055] In step S306, the signal transmission power of the first network in the target overlapping frequency band in the first target cell is increased, and / or the signal transmission power of the second network in the target overlapping frequency band in the second target cell is reduced, so as to increase the signal transmission power proportion of the first network in the target overlapping frequency band in the first target cell, and / or reduce the signal transmission power proportion of the second network in the target overlapping frequency band in the second target cell.

[0056] In some embodiments, the transmission power of the overlapping bandwidth of the large-bandwidth first network and the small-bandwidth second network can be adjusted to increase the ratio of the signal transmission power of the first network in the target overlapping frequency band to the total signal power of the target overlapping frequency band in the first target cell, and / or reduce the ratio of the signal transmission power of the second network in the target overlapping frequency band to the total signal power of the target overlapping frequency band in the second target cell, so as to improve the signal-to-noise ratio of the first network in the first target cell in the target overlapping frequency band. For example, if the downlink transmission power is adjusted, the downlink transmission power of the large-bandwidth first network in the first target cell in the target overlapping frequency band can be increased, and / or the downlink transmission power of the small-bandwidth second network in the second target cell in the target overlapping frequency band can be reduced. For specific implementation methods, please refer to Figures 5 to 7 .

[0057] In other embodiments, for example, if the downlink transmission power is adjusted, only the downlink transmission power of the target use frequency band of the large bandwidth first network in the first target cell in the target overlapping frequency band may be increased. For specific implementation methods, refer to Figures 8 to 10 .

[0058] According to the signal processing method provided by the embodiment of the present disclosure, by adjusting the transmission power of the large bandwidth first network on the partial bandwidth of frequency overlap, the influence of the co-frequency small bandwidth second network on the performance of the large bandwidth first network is reduced, the signal-to-noise ratio of the large bandwidth first network can be improved, the bandwidth utilization rate of the large bandwidth first network can be improved, the performance of the large bandwidth first network can be fully reflected, the user's positive perception of the large bandwidth first network can be enhanced, and the rapid development of the large bandwidth first network can be promoted.

[0059] Figure 4 is based on Figure 1 A schematic diagram of the initial state of a network is shown in FIG. Figure 4 As shown, the frequency band of the large-bandwidth 5G NR network is F1+F2, the transmission power is P1, and the first target cell set is Cnr; the frequency band of the small-bandwidth LTE network is F1, the transmission power is P2, and the second target cell set is Clte. In the F1 part, the large-bandwidth 5G NR network of the first target cell overlaps with the small-bandwidth LTE network of the adjacent second target cell, and the small-bandwidth LTE network interferes with the large-bandwidth 5G NR network in the F1 part.

[0060] Figure 5 is based on Figure 3 A flow chart of a signal processing method is shown in FIG. Figure 5 The method shown can be applied, for example, to Figure 4 , performed by network equipment in 5G NR networks.

[0061] refer to Figure 5 , the method 50 provided in the embodiment of the present disclosure may include the following steps.

[0062] In step S502, a target overlapping frequency band of the first network and the second network is obtained, where the target overlapping frequency band is the overlapping portion of the first frequency band and the second frequency band. Data is transmitted in the first network via the first frequency band and in the second network via the second frequency band. The bandwidth of the first frequency band is greater than the bandwidth of the second frequency band.

[0063] In some embodiments, reference Figure 4 The first network may be a 5G NR network, and the second network may be an LTE network. The bandwidth F1 of the overlapping portion of the large-bandwidth NR network and the small-bandwidth LTE network may be identified according to the network frequency band defined in the network planning or by network frequency band measurement.

[0064] In step S504, a first target cell covered by the first network and a second target cell covered by the second network are obtained, and the first target cell and the second target cell include the same geographical area.

[0065] In some embodiments, the first target cell set Cnr and the second target cell Clte may be identified based on the network coverage cells set in the network planning, or through system information exchange and the like.

[0066] In step S506, the downlink signal transmission power of the first network in the first target cell in the target overlapping frequency band is increased to a first preset power, and the downlink signal transmission power of the second network in the second target cell in the target overlapping frequency band is reduced to a second preset power.

[0067] In some embodiments, the downlink transmission power within the bandwidth F1 of the cell set Cnr may be increased from P1 to P11, and the downlink transmission power within the bandwidth F1 of the cell set Clte may be reduced from P2 to P21.

[0068] In some embodiments, the downlink signal transmission power of the first network in the first target cell in the remaining part of the first frequency band may be reduced, for example, step S508 may be included to keep the total transmission power of the NR network unchanged.

[0069] In other embodiments, if the transmitter power of the first network is sufficient, only the downlink signal transmission power of the first network in the first target cell in the target overlapping frequency band may be increased without reducing the downlink signal transmission power of the first network in the first target cell in the remaining part of the first frequency band, that is, step S508 is an optional step.

[0070] In step S508, the downlink signal transmission power of the first network in the first target cell in the third frequency band is reduced to a third preset power, where the third frequency band is a frequency band in the first frequency band except the target overlapping frequency band.

[0071] In some embodiments, the downlink transmission power within the bandwidth F2 of the cell set Cnr may be reduced from P1 to P12 accordingly.

[0072] Figure 6 is based on Figure 5 A pair shown Figure 4 Schematic diagram of the adjustment process of network transmission power in FIG. Figure 6 As shown, refer to Figure 4 The frequency band of the large-bandwidth 5G NR network 6002 (abbreviated as NR network in the figure) is F1+F2, and the frequency band of the small-bandwidth LTE network 6004 is F1. Figure 6 The illustrated process of adjusting the network transmit power may include the following steps. Figure 6 The cells in the same geographical area covered by the NR network and the LTE network are illustrated by taking adjacent cells as an example, but the present invention is not limited to this (refer to step S304).

[0073] In step S6022, the NR network learns that the NR network overlaps with the adjacent LTE network on the F1 frequency band. For a specific implementation, please refer to step S502.

[0074] Step S6024, identifying the NR and LTE network adjacent cell sets Cnr and Clte, may include identifying the NR network has a cell set Cnr that has an increased overlapping bandwidth downlink power requirement. The specific implementation method may refer to step S504.

[0075] Step S6042, identifying the NR and LTE network adjacent cell sets Cnr and Clte, may include identifying the LTE network cell set Clte that has a requirement for reducing overlapping bandwidth downlink power.

[0076] Step S6026, increase the downlink transmission power within the cell set Cnr bandwidth F1 from P1 to P11, and correspondingly reduce the downlink transmission power within the cell set Cnr bandwidth F2 from P1 to P12. For a specific implementation, refer to step S504.

[0077] Step S6044: the cell set Clte reduces the downlink transmission power within the bandwidth F1 from P2 to P21.

[0078] Figure 7 is based on Figure 5 and Figure 6 A pair shown Figure 4 Schematic diagram of the adjustment result of the network transmission power in FIG. Figure 7As shown, the downlink transmission power of the NR network within the bandwidth F1 of the cell set Cnr increases from P1 to P11, and the downlink transmission power of the NR network within the bandwidth F2 of the cell set Cnr decreases from P1 to P12; the cell set Clte reduces the downlink transmission power of the LTE network within the bandwidth F1 from P2 to P21.

[0079] According to the signal processing method provided in the embodiment of the present disclosure, while increasing the downlink transmission power of the overlapping bandwidth part of the large-bandwidth NR network, the downlink transmission power of the overlapping bandwidth part of the small-bandwidth LTE network is reduced, thereby ensuring that the total transmission power of the large-bandwidth NR network remains unchanged, improving the signal-to-noise ratio of the overlapping bandwidth part of the large-bandwidth NR network, improving the bandwidth utilization of the NR network, and fully reflecting the performance of the large-bandwidth NR network.

[0080] Figure 8 is based on Figure 3 FIG. 1 is a flowchart of another signal processing method. Figure 8 The method shown can be applied, for example, to Figure 4 , performed by network equipment in 5G NR networks.

[0081] refer to Figure 8 , the method 80 provided in the embodiment of the present disclosure may include the following steps.

[0082] In step S802, a target overlapping frequency band of the first network and the second network is obtained, where the target overlapping frequency band is the overlapping portion of the first frequency band and the second frequency band. Data is transmitted in the first network through the first frequency band and in the second network through the second frequency band. The bandwidth of the first frequency band is greater than the bandwidth of the second frequency band.

[0083] In some embodiments, the specific implementation of step S802 may refer to step S502.

[0084] In step S804, a first target cell covered by the first network and a second target cell covered by the second network are obtained, and the first target cell and the second target cell include the same geographical area.

[0085] In some embodiments, the specific implementation of step S804 may refer to step S504.

[0086] In step S806, a target used frequency band in the target overlapping frequency band is obtained.

[0087] In some embodiments, the target frequency band may be the actual available bandwidth in the target overlapping frequency band, or may be any one or more frequency bands in the target overlapping frequency band. Figure 4 The actual available bandwidth of F1 bandwidth of the network configuration cell set Cnr is F11, and F1 includes F11.

[0088] In step S808, the downlink signal transmission power of the first network in the first target cell in the target frequency band is increased to a fourth preset power.

[0089] In some embodiments, for example, the downlink transmission power per resource block (RB) in the F11 frequency band in Cnr may be increased from P1 to P11, while the downlink transmission power per RB in the F2 frequency band may be kept unchanged at P1.

[0090] In some embodiments, based on the bandwidth of the target frequency band and the increase of the fourth preset power relative to the first preset power, the downlink transmit power per RB of the frequency bands other than the target overlapping frequency band in the first frequency band can be adjusted accordingly to keep the total transmit power of the NR network unchanged. For example, step S810 can be included, and step S810 is an optional step.

[0091] In step S810, (if necessary) the downlink signal transmission power of the first network in the first target cell in the third frequency band is reduced to a fifth preset power, where the third frequency band is a frequency band in the first frequency band except the target overlapping frequency band.

[0092] In some embodiments, the downlink transmission power per RB in the F2 frequency band may be reduced. For example, it may be determined whether the downlink transmission power per RB in the F2 frequency band needs to be reduced to P12 based on the F11 bandwidth and P11.

[0093] Fig. 9 is based on Figure 8 Another pair shown Figure 4 Schematic diagram of the adjustment process of network transmission power in FIG. Fig. 9 As shown, refer to Figure 4 The frequency band of the large-bandwidth 5G NR network 9002 (abbreviated as NR network in the figure) is F1+F2. Fig. 9 The illustrated process of adjusting the network transmit power may include the following steps. Fig. 9 The cells in the same geographical area covered by the NR network and the LTE network are illustrated by taking adjacent cells as an example, but the present invention is not limited to this (refer to step S304).

[0094] In step S902, the NR network learns that the NR network overlaps with the adjacent LTE network on the F1 frequency band. For a specific implementation, please refer to step S502.

[0095] Step S904, identifying the NR and LTE network adjacent cell sets Cnr and Clte, may include identifying the NR network has a cell set Cnr that has an increased overlapping bandwidth downlink power requirement. The specific implementation method may refer to step S504.

[0096] Step S906: Obtain that the actually available bandwidth of the cell set Cnr F1 bandwidth in the NR network is F11 (F11 < F1). The specific implementation can refer to Step S806.

[0097] Step S908: The NR network increases the downlink transmit power of each RB in the F11 frequency band in Cnr from P1 to P11.

[0098] Step S910: (If necessary) The NR network adjusts the downlink transmit power of each RB in the F2 frequency band to P12. The specific implementation can refer to Step S810.

[0099] Fig.10 is based on Figure 8 and Fig. 9 shows another schematic diagram of the adjustment result of the network transmit power in Figure 4 .

[0108] The processing module 1104 may also be used to increase the downlink signal transmission power of the first network in the first target cell in the target overlapping frequency band to a first preset power, and reduce the downlink signal transmission power of the second network in the second target cell in the target overlapping frequency band to a second preset power.

[0109] The processing module 1104 may also be used to reduce the downlink signal transmission power of the first network in the first target cell in a third frequency band to a third preset power, where the third frequency band is a frequency band in the first frequency band except the target overlapping frequency band.

[0110] The processing module 1104 may also be used to: obtain a target used frequency band in the target overlapping frequency band; and increase the downlink signal transmission power of the first network in the first target cell in the target used frequency band to a fourth preset power.
