Description

Technical Field

[0001] This application relates to the field of wireless communication technologies, and in particular, to a network optimization method and a wireless communication system. Background Art

[0002] In the application of frequency band combinations in 3GPP standards, there are various interferences in radio frequency angles. When a terminal transmits a signal, devices such as radio frequency circuits and power amplifiers that process the signal are non-linear, which can lead to the generation of harmonics; when the terminal transmits 4G and 5G signals simultaneously, 4G harmonics and 5G harmonics are generated simultaneously, resulting in the generation of intermodulation signals. The decrease in the sensitivity of the victim frequency band is exactly the result of being affected by one or more interfering frequency bands, and the types of factors causing the decrease in the sensitivity of the victim frequency band can be summarized as reasons such as harmonics, intermodulation interference, inter-band isolation, and different levels of IMD (Intermodulation, intermodulation distortion).

[0003] As part of the terminal capabilities, the terminal can report information related to the frequency band combinations it supports to the network. Different frequency bands are associated with different MSDs (Maximum Sensitivity Degradation), and a larger MSD may cause the terminal to be unable to correctly receive downlink signals, resulting in difficulties in actually deploying frequency band configurations or frequency band combinations. To facilitate network scheduling on frequency band combinations, the 3GPP standard introduces a lower MSD capability, enabling the network to distinguish terminals with different MSDs, thereby maximizing the utilization of terminals with lower MSD capabilities.

[0004] However, in existing protocols, the wireless base station separation architecture does not support the reporting and configuration of lower MSDs. Therefore, in the case of maximum sensitivity degradation, the network can only schedule the entire frequency band combination and cannot send a lower MSD request to the terminal; at the same time, the network of existing protocols cannot distinguish terminals that do not support low MSD, support lower MSD, and lower MSD, resulting in the inability to effectively utilize low MSD terminals in scheduling and causing resource waste; in addition, the network of existing protocols cannot indicate the victim frequency band and the interfering frequency band to the terminal, cannot use existing frequency band filters to indicate the requested frequency band for lower MSD reports, the current MSD parameters act on all operating frequency bands, and the scheduling signaling is relatively complex. If new signaling is designed for indication, the signaling overhead is large.

[0005] In response to the above problems, no effective solution has been proposed yet. Summary of the Invention

[0043] To enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0044] It should be noted that the terms "first", "second", etc. in the specification, claims and drawings of this application are used to distinguish similar objects, and do not necessarily need to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of this application described here can be implemented in an order different from those illustrated or described here.

[0045] To better understand the embodiments of this application, some nouns or terms that appear in the description process of the embodiments of this application are translated and explained as follows:

[0046] MSD: A phenomenon that occurs in a communication system. In a wireless communication system, MSD is a problem of reduced sensitivity caused by various factors such as harmonic interference and intermodulation interference of the terminal; in an optical fiber communication system, MSD is a reduction in the signal strength or sensitivity of the optical fiber receiver caused by factors such as bending, stretching of the optical fiber, and temperature, humidity, and vibration in the environment. MSD will significantly reduce the efficiency and reliability of the communication system and may cause problems such as transmission errors and packet loss.

[0047] IMD: An interference phenomenon. When two or more signals are used in a nonlinear system, the spectrum at the output of the nonlinear device consists not only of the original signals, but also includes the sum and difference between the input signals and their harmonics.

[0048] RRC (Radio Resource Control): Manage, control, and schedule radio resources through certain strategies and means.

[0049] Embodiment 1

[0050] In the existing protocol, the wireless base station separation architecture does not support the reporting and configuration of lower MSD information. In the case of maximum sensitivity attenuation, the network can only schedule the entire frequency band combination and cannot send a lower MSD request to the terminal. At the same time, the existing protocol cannot effectively utilize low-MSD terminals during scheduling, resulting in waste of resources. In addition, the network of the existing protocol cannot indicate the victim frequency band and interference frequency band to the terminal, and cannot use the existing frequency band filter to indicate the requested frequency band of the lower MSD report. The current MSD parameters act on all operating frequency bands, and the scheduling signaling is relatively complex. If a new signaling is designed for indication, the signaling overhead is large.

[0051] To solve the above problems, an embodiment of the present application provides a wireless communication system, as Figure 1 shown. The system at least includes: a base station centralized entity 11, a base station separation entity 12, and a target terminal 13, where:

[0052] The base station centralized entity 11 can send a first in-station message to the base station separation entity 12 through an in-station interface message. The first in-station message includes: a terminal identifier and a first RRC message. The first RRC message includes: a lower MSD request, and the lower MSD request is used to obtain the support of the target terminal for the lower MSD capability in the form of a target frequency band. The target frequency band form includes at least one of the following: one frequency band, multiple frequency bands, one frequency band combination, and multiple frequency band combinations;

[0053] The base station separation entity 12 can send the lower MSD request to the target terminal 13 through the first RRC message;

[0054] The target terminal 13 can feedback a terminal reply message to the base station separation entity 12. The terminal reply message includes: lower MSD capability information, and the lower MSD capability information is used to indicate whether the target terminal supports the lower MSD capability when the frequency band is an interfered frequency band with sensitivity attenuation;

[0055] The base station separation entity 12 can send the terminal reply message to the base station centralized entity 11 through an in-station interface message;

[0056] The base station centralized entity 11 can send a first indication to the base station separation entity 12 through an in-station interface message. The first indication is used to indicate the base station separation entity to enable the lower MSD configuration.

[0057] The functions of each module of the wireless communication system are described below in combination with a specific implementation process.

[0058] Among them, the lower MSD is the optimization result of the MSD of the original inter-band aggregated carrier / enhanced non-standalone networking / dual-reception combination. When the terminal achieves lower MSD performance after enhancement, it can report the relevant MSD capabilities. In some frequency band combinations, the MSD before optimization may be as high as 30 dB. It can be understood that the lower MSD is the optimized MSD, and the interface within the base station can be the F1 interface.

[0059] Optionally, the lower MSD capability information is used to indicate whether the target terminal supports the lower MSD capability when the frequency band is an interfered frequency band with sensitivity attenuation.

[0060] Optionally, the types of the first in-station message usually include: UE context setup request, UE context modification request. The first RRC message includes: a common field for terminal capability request, and the common field for terminal capability request includes: lower MSD request.

[0061] Specifically, the target terminal may support the frequency combinations of all frequency bands, while the network only cares about specific content. Therefore, the lower MSD request can be used to filter information by specifying the power class, thereby saving signaling overhead.

[0062] Optionally, the lower MSD request usually includes: a common filter field for UE-CapabilityRequestFilterCommon, a FreqBandList. Among them, the common filter field for UE-CapabilityRequestFilterCommon includes: specifying the MSD power level, and the FreqBandList is used to indicate the interfered frequency band, the interfering frequency band, and the frequency band combination including the interfered frequency band and the interfering frequency band for which the lower MSD is requested.

[0063] Optionally, the types of the terminal reply message usually include: terminal context setup reply, terminal context modification reply. The terminal reply message includes: UECapabilityInformation, and the UECapabilityInformation includes: lower MSD capability information.

[0064] If the target terminal supports a lower MSD, the UE-CapabilityRequestFilterCommon in the terminal capability request exists but is empty, and the terminal capability information includes: the lower MSD capability information corresponding to the highest power level supported by the frequency band combination including the interfered band and the interfering band.

[0065] For example, when the target terminal receives the first in-station message sent by the base station separation entity, if the target terminal supports a lower MSD and the UE-CapabilityRequestFilterCommon in the terminal capability request exists but is empty, that is, the current lower MSD request (lowerMSDRequest) does not make a requirement for the power class, the target terminal will include the lower MSD capability information corresponding to the highest carrier aggregation power level supported by the frequency band combination of the interfered band and the interfering band in the terminal reply message and send it to the base station separation entity. After receiving the terminal reply message, the base station separation entity will not decode this information, but directly send the terminal reply message to the base station central entity. The base station central entity configures the first indication based on the lower MSD capability information in the terminal reply message, and after the configuration is completed, sends the first indication to the base station separation entity. The base station separation entity identifies this indication information and performs MSD configuration according to the identification result.

[0066] If the target terminal supports a lower MSD, the UE-CapabilityRequestFilterCommon in the terminal capability request includes a specified MSD power level, and the target terminal supports the lower MSD at the specified MSD power level, the terminal capability information includes: the lower MSD capability information corresponding to the specified MSD power level, and the lower MSD capability information corresponding to the highest power level supported by the frequency band combination including the interfered band and the interfering band.

[0067] For example, when the target terminal receives the first in-station message sent by the base station separation entity, if the terminal supports a lower MSD and the current lower MSD request (lowerMSDRequest) sets the power class to the third class (Class III), the terminal will include the lower MSD capability information corresponding to Class III and the lower MSD capability information corresponding to the highest carrier aggregation power level supported by the frequency band combination of the interfered band and the interfering band in the terminal reply message and send it to the base station separation entity. After receiving the terminal reply message, the base station separation entity will not decode this information, but directly send the terminal reply message to the base station central entity. The base station central entity configures the first indication based on the lower MSD capability information in the terminal reply message, and after the configuration is completed, sends the first indication to the base station separation entity. The base station separation entity identifies this indication information and performs MSD configuration according to the identification result.

[0068] It should be noted that only when there is a lower MSD request can a target terminal supporting a lower MSD indicate the lower MSD capability.

[0069] Optionally, the lower MSD capability information usually includes: interference band information for indicating the interfered band, interference band information for indicating a single interfering band that causes the sensitivity attenuation of the interfered band, band combination information for indicating multiple interfering bands that cause the sensitivity attenuation of the interfered band, MSD level class for indicating the lower MSD threshold, MSD power class corresponding to the lower MSD threshold, and MSD type applicable to the lower MSD threshold.

[0070] It can be understood that if the sensitivity attenuation of the interfered band is caused by one band, the band information in the lower MSD capability information only has the interference band information for indicating a single interfering band that causes the sensitivity attenuation of the interfered band, and the band information at this time cannot indicate additional interfering bands; if the sensitivity attenuation of the interfered band is caused by more than one band, the band information in the lower MSD capability information has the band combination information for indicating the interfering bands that cause the sensitivity attenuation of the interfered band, and the band information at this time can indicate additional interfering bands.

[0071] Specifically, the MSD level class usually includes: first level classI, second level classII, third level classIII, fourth level classIV, fifth level classV, sixth level classVI, seventh level classVII, eighth level classVIII. Among them, each level is used to indicate the intensity of the interference on the band, and each level corresponds to a lower MSD threshold. An example of the MSD level class is shown in Table 1 below.

[0072] Table 1

[0073]

[0074]

[0075] Specifically, the MSD power class is used to indicate the power class applicable to each level in the MSD level. Among them, the power class usually includes: first power class, second power class, third power class, fourth power class. Each power class is used to indicate the transmit power of the target terminal on the corresponding band.

[0076] It should be noted that if the MSD power level is too high, radiation will be generated. The 3GPP standard stipulates that the terminal requires an MSD power level, and in the embodiments of the present application, the power can be set to PC3, PC2, PC1.5, and PC1.

[0077] Specifically, the MSD type is used to indicate the type of cause that causes the sensitivity attenuation of the interfered band applicable to each level in the MSD level. Among them, the types of causes usually include: harmonics, intermodulation interference, inter-band isolation, second-order intermodulation distortion, third-order intermodulation distortion, fourth-order intermodulation distortion, fifth-order intermodulation distortion, full type. The full type represents all types of causes defined by a lower MSD threshold. The MSD type can be any one or any combination of the above types of causes.

[0078] In the embodiments of the present application, the base station centralized entity can send a first intra-station message to the base station separation entity through an intra-base station interface message. Among them, the first intra-station message includes: a terminal identifier and a first RRC message. The first RRC message includes: a lower MSD request, and the lower MSD request is used to obtain the support of the target terminal for the lower MSD capability in the form of the target frequency band. The target frequency band form includes at least one of the following: one frequency band, multiple frequency bands, one frequency band combination, multiple frequency band combinations; the base station separation entity can send the lower MSD request to the target terminal through the first RRC message; the target terminal can feedback a terminal reply message to the base station separation entity. Among them, the terminal reply message includes: lower MSD capability information, and the lower MSD capability information is used to indicate whether the target terminal supports the lower MSD capability when the frequency band is an interfered band with sensitivity attenuation; the base station separation entity can send the terminal reply message to the base station centralized entity through an intra-base station interface message; the base station centralized entity can send a first indication to the base station separation entity through an intra-base station interface message, and the first indication is used to indicate the base station separation entity to enable the lower MSD configuration. Among them, the lower MSD request and the lower MSD capability are transmitted through the intra-base station interface message, so that the base station can perform filter configuration on the specified victim frequency band and interference frequency band, and flexibly control the power levels of different frequency bands in the frequency band combination at the maximum sensitivity attenuation, ensuring the flexibility and effectiveness of the network optimization strategy, and effectively solving the technical problem that the existing protocol in the base station separation architecture cannot meet the transmission requirements of the lower MSD information.

[0079] Embodiment 2

[0080] Based on the wireless communication system, the embodiments of the present application provide a network optimization method implemented by a base station separation entity, as Figure 2 shown. The method includes the following steps:

[0081] Step S202: Receive the first in-station message sent by the base station centralized entity through the in-station interface message. The first in-station message includes: a terminal identifier and a first RRC message. The first RRC message includes: a lower MSD request, which is used to obtain the support of the target terminal for the lower MSD capability in the target frequency band form. The target frequency band form includes at least one of the following: one frequency band, multiple frequency bands, one frequency band combination, and multiple frequency band combinations.

[0082] Step S204: Send the lower MSD request to the target terminal through the first RRC message.

[0083] Step S206: Receive the first indication sent by the base station centralized entity through the in-station interface message. The first indication is used to instruct the base station separation entity to enable the lower MSD configuration.

[0084] The following describes each step of the network optimization method in combination with a specific implementation process.

[0085] Among them, the lower MSD is the optimization result of the original inter-band aggregated carrier / enhanced non-standalone networking / dual reception combination MSD. When the terminal achieves enhanced lower MSD performance, it can report the relevant MSD capability. In some frequency band combinations, the pre-optimization MSD may be as high as 30 dB. It can be understood that the lower MSD is the optimized MSD, and the in-station interface can be the F1 interface.

[0086] As an optional implementation manner, after sending the lower MSD request to the target terminal through the first RRC message, the base station separation entity can receive the terminal reply message fed back by the target terminal and send the terminal reply message to the base station centralized entity through the in-station interface message. The terminal reply message includes: lower MSD capability information.

[0087] Optionally, the lower MSD capability information is used to indicate whether the target terminal supports the lower MSD capability when the frequency band is an interfered frequency band with sensitivity attenuation.
