Description

Technical Field

[0001] The present application relates to the field of wireless communication technology, and in particular to a message processing method and a wireless communication system. Background Art

[0002] Customized outdoor macro base station is a device that implements the wireless access function of LTE (Long Time Evolution) technology and NR (New Radio) technology. It adopts an integrated design that combines BBU (Building Base band Unit) and RRU (Remote Radio Unit). A complete set of customized outdoor macro base station includes an integrated machine and a remote RRU. However, in terms of spectrum resource configuration, the customized outdoor station adopts a static configuration of frequency resources, and NR and LTE have exclusive independent frequency resources.

[0003] 4G / 5G DSS (dynamic spectrum sharing) technology shares spectrum resources according to the traffic requirements of different standards. For the collaborative work of 4G and 5G, when LTE has surplus capacity, NR is dynamically introduced to dynamically allocate spectrum resources to different users according to the business needs of LTE and NR to maximize the utilization of spectrum resources.

[0004] However, the current customized outdoor base stations use a static method for spectrum resource configuration and do not support the DSS function, while some macro base stations from different manufacturers on the market already support DSS. In heterogeneous system networking scenarios, especially when macro base stations that support DSS coexist with customized outdoor macro base stations that do not enable DSS, users at the edge of base station coverage are interfered with by neighboring base stations. This interference mainly comes from the interference of signals of different standards configured in the same frequency band, that is, the information symbols of the neighboring LTE interfere with the NR information symbols. Therefore, when a base station that does not enable DSS is deployed in a base station scenario with DSS enabled, it is a heterogeneous system networking of different manufacturers, and interference coordination is required for base station signals of different standards at the same frequency at the same time.

[0005] To address the above-mentioned problems, no effective solution has been proposed yet. Summary of the invention

[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0033] It should be noted that the terms "first", "second", etc. in the specification, claims and drawings of the present application are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein.

[0034] In order to better understand the embodiments of the present application, some nouns or terms that appear in the description of the embodiments of the present application are first translated and explained as follows:

[0035] OFDMA (Orthogonal Frequency Division Multiple Access) technology: A wireless communication technology mainly used in 4G and 5G networks. It allows multiple users to communicate using the same frequency band at the same time, but achieves orthogonality by dividing the frequency band into multiple subcarriers, thereby avoiding interference between users.

[0036] RSMA (Rate-Splitting Multiple Access) technology: A new type of non-orthogonal multiple access technology, which is considered to be one of the potential technologies for future 6G networks. RSMA achieves significant improvements in spectrum efficiency and energy efficiency by splitting and reconstructing information at the transmitting end and using serial interference cancellation technology at the receiving end.

[0037] Example 1

[0038] According to an embodiment of the present application, a wireless communication system is first provided, such as Figure 1As shown, the wireless communication system at least includes: a single antenna terminal 11 and multiple base stations in a hybrid network, including: a dynamic spectrum sharing base station 12 (1-m) and a static spectrum configuration base station 13 (1-n).

[0039] In the system, each base station can use OFDMA technology to modulate the first message to be transmitted to the target frequency band, wherein the first message includes multiple first sub-messages, and the type of the first sub-message includes at least one of the following: 4G message and 5G message; determine the frequency band type of the target frequency band according to the configuration of the target frequency band by the static spectrum configuration base station; determine the message type of each first sub-message according to the frequency band type, wherein the message type includes: public message and private message; use the public code set of RSMA technology to encode the first sub-message of each message type that is a public message, and use the private code set of RSMA technology to encode the first sub-message of each message type that is a private message, and send the obtained multiple second sub-messages as second messages to the single antenna terminal 11.

[0040] The single-antenna terminal 11 can receive multiple second messages sent by multiple base stations; use the public code set of RSMA technology to decode each second sub-message, use each first sub-message successfully decoded as the target public message, and use the private code set of RSMA technology to decode each second sub-message that has not been successfully decoded again, use the decoded first sub-message from the target base station as the target private message, and use the decoded first sub-message from the non-target base station as noise; for each target public message or target private message, determine the frequency band type and message type corresponding to the target public message or target private message, and configure the target public message or target private message as a 4G message or a 5G message according to the frequency band type and message type corresponding to the target public message or target private message.

[0041] The functions of each module of the wireless communication system are described below in conjunction with a specific implementation process.

[0042] In wireless communication systems, OFDMA technology is widely used. It divides available frequency band resources into multiple orthogonal subcarriers and allocates these subcarriers to different users or services, thereby achieving parallel communication between multiple users on the same frequency band.

[0043] Optionally, in an embodiment of the present application, when using OFDMA technology, the base station may first determine a target frequency band suitable for applying OFDMA technology. After determining the target frequency band, multiple first sub-messages on multiple sub-carriers to be transmitted are obtained. These sub-messages may be 4G messages, 5G messages, or a combination of the two. Then, these first sub-messages are uniformly modulated to the target frequency band using OFDMA technology. In this way, both 4G and 5G messages can coexist and be transmitted efficiently in the same frequency band.

[0044] As an optional implementation method, since the base station design of the hybrid network includes two types: static spectrum configuration base station and dynamic spectrum sharing base station, and in the static spectrum configuration base station, the use of the frequency band is pre-planned and fixed, and each frequency band serves a specific network type (such as 4G or 5G). Furthermore, when determining the target frequency band as mentioned above, in fact, for the static spectrum configuration base station, it is selecting a frequency band with a clearly specified purpose. Therefore, when determining the frequency band type, the base station of the hybrid network determines the frequency band type of the target frequency band according to the configuration of the static spectrum configuration base station for the target frequency band. The frequency band types are: long-term evolution frequency band and new air interface frequency band. Figure 2 This is a schematic diagram of a hybrid network structure of the present application. Figure 2 Among them, DSS BS1 and DSS BS2 are dynamic spectrum sharing base stations, which adopt the method of dynamic sharing of frequency resources to support 15M new air interface band NR and long-term evolution band LTE. Static BS1 is a static spectrum configuration base station, which adopts the method of static configuration of frequency resources to statically configure 10M long-term evolution band LTE and 5M new air interface band NR.

[0045] Optionally, after determining the frequency band type of the target frequency band, in order to ensure that the single-antenna terminal can correctly parse and process the received message, a clear frequency band type identification code can be added to the message so that the single-antenna terminal can identify the source frequency band type of the message and adjust the corresponding decoding and processing strategies accordingly. Specifically, it can be implemented in the following way: when the frequency band type is a long-term evolution frequency band, a first message identification code is added to each first sub-message to reflect that the frequency band corresponding to the first sub-message is a long-term evolution frequency band; when the frequency band type is a new air interface frequency band, a second message identification code is added to each first sub-message to reflect that the frequency band corresponding to the first sub-message is a new air interface frequency band.

[0046] For each first sub-message, after determining the frequency band type of the target frequency band, it is also necessary to determine the message type of the first sub-message, specifically: if the frequency band type is the long-term evolution band and the first sub-message is a 4G message, then the message type of the first sub-message is determined to be a public message; if the frequency band type is the long-term evolution band and the first sub-message is a 5G message, then the message type of the first sub-message is determined to be a private message; if the frequency band type is the new air interface band and the first sub-message is a 4G message, then the message type of the first sub-message is determined to be a private message; if the frequency band type is the new air interface band and the first sub-message is a 5G message, then the message type of the first sub-message is determined to be a public message.

[0047] Optionally, after determining the message type of each first sub-message based on the frequency band type, the base station of the hybrid network may also divide the message type, wherein: for each first sub-message, when the message type of the first sub-message is a public message, a first message segmentation field is added to the first sub-message to reflect that the message type of the first sub-message is a public message; when the message type of the first sub-message is a private message, a second message segmentation field is added to the first sub-message to reflect that the message type of the first sub-message is a private message.

[0048] Table 1 gives a first sub-message discrimination and segmentation correspondence table, as shown in Table 1, defining a 1-bit message discrimination code JUDGE_C and a 2-bit message segmentation field CHANGE_C. For a base station configured with a static spectrum, if the frequency band type is a long-term evolution frequency band, the first message discrimination code JUDGE_C = 0, the first sub-message of the frequency band is a public message, and the first message segmentation field CHANGE_C = 01; if the frequency band type in the static spectrum is a new air interface frequency band, the second message discrimination code JUDGE_C = 1, the first sub-message of the frequency band is a public message, and the first message segmentation field CHANGE_C = 01. For dynamic spectrum sharing base stations, if the frequency band type is a long-term evolution band, the first message identification code JUDGE_C=0, the 4G message of this frequency band is a public message, the corresponding first message segmentation field CHANGE_C=01, the 5G message of this frequency band is a private message, and the corresponding second message segmentation field CHANGE_C=10; if the frequency band type is a new air interface band, the first message identification code JUDGE_C=1, the 5G message of this frequency band is a public message, the corresponding first message segmentation field CHANGE_C=01, the 4G message of this frequency band is a private message, and the corresponding second message segmentation field CHANGE_C=10.

[0050]

[0051]

[0052] As an optional implementation, since public messages need to be received by all terminals or specific terminal groups, while private messages are only for specific terminals, it is necessary to distinguish between these two message types during encoding. Specifically: the first sub-message of each message type that is a public message is encoded using the public code set of RSMA technology; the first sub-message of each message type that is a private message is encoded using the private code set of RSMA technology, and the encoded second message is transmitted to the single antenna terminal.

[0053] Figure 3A schematic diagram of a message identification and segmentation process of an embodiment of the present application is given, such as Figure 3 As shown, the 1-bit message identification code JUDGE_C=0 of the long-term evolution frequency band LTE, wherein for the 2-bit message segmentation field CHANGE_C, when the message transmitted is a 5G message, i.e., a private message, then CHANGE_C=10, and when the message transmitted is a 4G message, i.e., a public message, then CHANGE_C=01; the 1-bit message identification code JUDGE_C=1 of the new air interface frequency band NR, wherein for the 2-bit message segmentation field CHANGE_C, when the message transmitted is a 5G message, i.e., a public message, then CHANGE_C=01, and when the message transmitted is a 4G message, i.e., a private message, then CHANGE_C=10. Then use the code set of RSMA technology to encode all types of messages, wherein private messages correspond to private code sets, and public messages correspond to public code sets. The encoded message is sent.

[0054] Figure 4 A schematic diagram of a process of sending a message by a base station in an optional hybrid network of an embodiment of the application is given. Figure 4 In the process, the base station side sends 4G or 5G messages, where for each specific frequency band, the static spectrum configuration base station has only one frequency band type, namely the new radio frequency band NR or the long term evolution frequency band LTE, while the dynamic spectrum sharing DSS base station can have both types at the same time. The frequency band type of the frequency band is determined according to the configuration of the static spectrum configuration base station for the frequency band, and the 4 / 5G message of the frequency band is determined whether it is a private message or a public message according to the frequency band type and is segmented. The segmented message is encoded to obtain the code stream of the hybrid networking base station, and the code stream is transmitted downlink wirelessly, i.e., transmitted to the single antenna terminal.

[0055] Optionally, the single-antenna terminal receives multiple second messages sent by multiple base stations in a hybrid network, and each second message includes multiple second sub-messages.

[0056] After a single antenna receives a message, it first regards all private messages in the second sub-message as noise, then uses the public code set of the RSMA technology to decode the public message in the second sub-message, and uses the first sub-messages successfully decoded as the target public message. Then, it uses the private code set of the RSMA technology to decode all private messages in the second sub-message, and uses the decoded first sub-message from the target base station as the target private message, and uses the decoded first sub-messages from non-target base stations as noise.

[0057] Optionally, after taking each first sub-message successfully obtained by decoding as the target common message, the single-antenna terminal may also merge the target common messages corresponding to each second sub-message on the same sub-carrier in the same frequency band.

[0058] As an optional implementation manner, when a single-antenna terminal determines the frequency band type and message type corresponding to a target public message or a target private message, for each target public message or target private message, the frequency band type corresponding to the target public message or the target private message is determined based on the message identification code in the target public message or the target private message, wherein the types of message identification codes include: a first message identification code used to reflect that the frequency band type corresponding to the message is a long-term evolution frequency band and a second message identification code used to reflect that the frequency band type corresponding to the message is a new air interface frequency band; the message type corresponding to the target public message or the target private message is determined based on the message segmentation field in the target public message or the target private message, wherein the types of message segmentation fields include: a first message segmentation field used to reflect that the message type corresponding to the message is a public message and a second message segmentation field used to reflect that the message type corresponding to the message is a private message.

[0059] Optionally, in the process of configuring the target public message or target private message as a 4G message or a 5G message based on the frequency band type and the message type, the single-antenna terminal can take the following steps: for each target public message or target private message, when the frequency band type of the target public message or target private message is a long-term evolution band and the message type is a public message, configure the target public message or target private message as a 4G message; when the frequency band type of the target public message or target private message is a long-term evolution band and the message type is a private message, configure the target public message or target private message as a 5G message; when the frequency band type of the target public message or target private message is a new air interface band and the message type is a public message, configure the target public message or target private message as a 5G message; when the frequency band type of the target public message or target private message is a new air interface band and the message type is a private message, configure the target public message or target private message as a 4G message.

[0060] Figure 5 The specific process of determining whether a message is a 4G or 5G message after a single-antenna terminal receives the message is given. Figure 5 In the example, the single-antenna terminal receives the second message and first decodes it using the public code set. The successfully decoded message can be regarded as a public message. The failed decoded message is then decoded using the private code set. After the private code set is successfully decoded, the message from the target base station is a private message, and the message from the non-target base station is considered as noise. For a public message, if the message identification code is used to determine that the frequency band is a long-term evolution frequency band type, the public message is a 4G message. If it is a new air interface frequency band type, the public message is a 5G message. For a private message, if the message identification code is used to determine that the frequency band is a long-term evolution frequency band type, the private message is a 5G message. If it is a new air interface frequency band type, the private message is a 4G message.

[0061] Figure 6 A schematic diagram of an optional process of a single-antenna terminal receiving a message in an embodiment of the present application is provided, such as Figure 6 As shown, a single-antenna terminal receives multiple messages from a base station in a hybrid network. For each frequency band, if the frequency band type is a long-term evolution LTE band, the received public message is a long-term evolution LTE 4G message, the private message from the target base station is a new air interface NR 5G message, and the private message from the non-target base station is noise. For another frequency band, if the frequency band type is a new air interface NR band, the received public message is a new air interface NR 5G message, and the received private messages are all from non-target base stations, then all private messages are regarded as noise.

[0062] In an embodiment of the present application, for a hybrid networking scenario of a base station with static spectrum configuration and a base station with dynamic spectrum sharing, the base station side uses OFDMA technology to modulate the message, and based on RSMA technology, performs frequency band discrimination and message type segmentation on the modulated message, converts it into a public message and a private message, and encodes and transmits it using the corresponding code set; the terminal side decodes the public messages and private messages sent by all base stations based on RSMA technology, eliminates the inter-symbol interference in the same frequency band, and then merges the public messages in the same frequency band and the same subcarrier to reduce interference between base stations. This application solves the technical problem that the transmission signal is susceptible to interference from neighboring base stations in a hybrid networking scenario of a base station with static spectrum configuration and a base station with dynamic spectrum sharing.

However, in some cases, the steps shown or described can be executed in a different order from this.

[0066] Step S702, modulating a first message to be transmitted to a target frequency band by using OFDMA technology, wherein the first message includes a plurality of first sub-messages, and the type of the first sub-message includes at least one of the following: a 4G message and a 5G message;

[0067] Step S704, determining the frequency band type of the target frequency band according to the configuration of the target frequency band by the static spectrum configuration base station;

[0068] Step S706, determining the message type of each first sub-message according to the frequency band type, wherein the message type includes: public message and private message;

[0069] Step S708: Encode the first sub-messages of the corresponding message types using different code sets of the RSMA technology, and send the obtained multiple second sub-messages as second messages to the single-antenna terminal.

[0070] The message processing method is described below in conjunction with a specific implementation process.

[0071] In wireless communication systems, OFDMA technology is widely used. It divides available frequency band resources into multiple orthogonal subcarriers and allocates these subcarriers to different users or services, thereby achieving parallel communication between multiple users on the same frequency band.

[0072] Optionally, when the system uses OFDMA technology, the system needs to first determine a target frequency band suitable for applying OFDMA technology. After determining the target frequency band, multiple first sub-messages on multiple sub-carriers to be transmitted are obtained. These sub-messages may be 4G messages, 5G messages, or a combination of the two. Then, these first sub-messages are uniformly modulated to the target frequency band using OFDMA technology. In this way, both 4G and 5G messages can coexist and be transmitted efficiently in the same frequency band.

[0073] As an optional implementation method, since the base station design of the hybrid network includes two types: static spectrum configuration base station and dynamic spectrum sharing base station, and in the static spectrum configuration base station, the use of the frequency band is pre-planned and fixed, and each frequency band serves a specific network type (such as 4G or 5G). Furthermore, when determining the target frequency band as mentioned above, in fact, for the static spectrum configuration base station, it is selecting a frequency band with a clearly specified purpose. Therefore, when determining the frequency band type, the base station of the hybrid network determines the frequency band type of the target frequency band according to the configuration of the static spectrum configuration base station for the target frequency band. The frequency band types are: long-term evolution frequency band and new air interface frequency band.

[0074] Optionally, after determining the frequency band type of the target frequency band, in order to ensure that the single-antenna terminal can correctly parse and process the received message, a clear frequency band type identification code can be added to the message so that the single-antenna terminal can identify the source frequency band type of the message and adjust the corresponding decoding and processing strategies accordingly. Specifically, it can be implemented in the following way: when the frequency band type is a long-term evolution frequency band, a first message identification code is added to each first sub-message to reflect that the frequency band corresponding to the first sub-message is a long-term evolution frequency band; when the frequency band type is a new air interface frequency band, a second message identification code is added to each first sub-message to reflect that the frequency band corresponding to the first sub-message is a new air interface frequency band.

[0075] For each first sub-message, after determining the frequency band type of the target frequency band, it is also necessary to determine the message type of the first sub-message, specifically: if the frequency band type is the long-term evolution band and the first sub-message is a 4G message, then the message type of the first sub-message is determined to be a public message; if the frequency band type is the long-term evolution band and the first sub-message is a 5G message, then the message type of the first sub-message is determined to be a private message; if the frequency band type is the new air interface band and the first sub-message is a 4G message, then the message type of the first sub-message is determined to be a private message; if the frequency band type is the new air interface band and the first sub-message is a 5G message, then the message type of the first sub-message is determined to be a public message.

[0076] Optionally, after determining the message type of each first sub-message based on the frequency band type, the base station of the hybrid network may also divide the message type, wherein: for each first sub-message, when the message type of the first sub-message is a public message, a first message segmentation field is added to the first sub-message to reflect that the message type of the first sub-message is a public message; when the message type of the first sub-message is a private message, a second message segmentation field is added to the first sub-message to reflect that the message type of the first sub-message is a private message.

[0077] As an optional implementation, since public messages need to be received by all terminals or specific terminal groups, while private messages are only for specific terminals, it is necessary to distinguish between these two message types during encoding. Specifically: the first sub-message of each message type that is a public message is encoded using the public code set of RSMA technology; the first sub-message of each message type that is a private message is encoded using the private code set of RSMA technology, and the encoded second message is transmitted to the single antenna terminal.

[0078] It should be noted that the steps of the message processing method in the embodiment of the present application correspond one-to-one to the implementation steps of the wireless communication system in Example 1. Since a detailed description has been given in Example 1, some details not reflected in this embodiment can be referred to Example 1 and will not be repeated here.

[0080] Based on the wireless communication system provided in Example 1, the embodiment of the present application also provides another message processing method, which is applied to a single antenna terminal. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flowchart. However, in some cases, the steps shown or described can be executed in an order different from this.

[0081] Figure 8is a flow chart of a message processing method provided according to an embodiment of the present application, such as Figure 8 As shown, the method comprises the following steps:

[0082] S802, receiving multiple second messages sent by multiple base stations in a hybrid network, where the types of the multiple base stations include: static spectrum configuration base stations and dynamic spectrum sharing base stations, and each second message includes multiple second sub-messages;

[0083] S804, using the public code set of the RSMA technology to decode each second sub-message, using each first sub-message successfully decoded as the target public message, and using the private code set of the RSMA technology to decode each second sub-message that was not successfully decoded again, using the decoded first sub-message from the target base station as the target private message, and using each first sub-message decoded from the non-target base station as noise;

[0084] S806: For each target public message or target private message, determine the frequency band type and message type corresponding to the target public message or target private message, and configure the target public message or target private message as a 4G message or a 5G message according to the frequency band type and the message type.

[0085] The above message processing method is described below in conjunction with a specific implementation process.

[0086] Optionally, a single-antenna terminal receives multiple second messages sent by multiple base stations in a hybrid network, each second message including multiple second sub-messages; then uses the public code set of the RSMA technology to decode each second sub-message, and uses each first sub-message successfully decoded as a target public message, and uses the private code set of the RSMA technology to decode each second sub-message that has not been successfully decoded again, and uses the decoded first sub-message from the target base station as a target private message, and uses each first sub-message decoded from a non-target base station as noise.

[0087] Optionally, after taking each first sub-message successfully obtained by decoding as the target common message, the single-antenna terminal may also merge the target common messages corresponding to each second sub-message on the same sub-carrier in the same frequency band.

[0088] As an optional implementation manner, when a single-antenna terminal determines the frequency band type and message type corresponding to a target public message or a target private message, for each target public message or target private message, the frequency band type corresponding to the target public message or the target private message is determined based on the message identification code in the target public message or the target private message, wherein the types of message identification codes include: a first message identification code used to reflect that the frequency band type corresponding to the message is a long-term evolution frequency band and a second message identification code used to reflect that the frequency band type corresponding to the message is a new air interface frequency band; the message type corresponding to the target public message or the target private message is determined based on the message segmentation field in the target public message or the target private message, wherein the types of message segmentation fields include: a first message segmentation field used to reflect that the message type corresponding to the message is a public message and a second message segmentation field used to reflect that the message type corresponding to the message is a private message.

[0089] As an optional implementation manner, when a single-antenna terminal configures a target public message or a target private message as a 4G message or a 5G message based on the frequency band type and the message type, the following steps can be taken: for each target public message or target private message, when the frequency band type of the target public message or the target private message is a long-term evolution band and the message type is a public message, the target public message or the target private message is configured as a 4G message; when the frequency band type of the target public message or the target private message is a long-term evolution band and the message type is a private message, the target public message or the target private message is configured as a 5G message; when the frequency band type of the target public message or the target private message is a new air interface band and the message type is a public message, the target public message or the target private message is configured as a 5G message; when the frequency band type of the target public message or the target private message is a new air interface band and the message type is a public message, the target public message or the target private message is configured as a 4G message.
