Description

Spectrum sharing system for different operators co-built network physical layer

Technical Field

The application relates to the technical field of spectrum sharing of different operators, in particular to a spectrum sharing system of a co-established network physical layer of different operators.

Background

Wireless mobile communication technology is facing increasing demands. According to the current development trend, the 5G system performs corresponding standardized support for enhancing characteristics of mobile broadband (emmbb), ultra-reliable low-delay communication (URLLC), large-scale machine type communication (mctc), and the like. Meanwhile, the spectrum sharing technology is correspondingly researched between 4G and 5G systems and between different operators, and efficient spectrum use is continuously pursued for wireless communication systems.

In wireless communication systems, spectrum resources have been the primary resources necessary for operators to deploy networks. Wireless communication developments are, to date, in large-scale deployment applications of 5GNR systems. Spectrum resources owned by different operators are characterized by fragmentation and discretization, and adjacent spectrum resources among different operators cause interference problems. Meanwhile, the NR system supports the technology of co-building NR networks through shared frequency spectrum among different operators in consideration of the problem of network deployment cost. However, the sharing method supported in the current standard only supports the 5G Multi-Operator Core Network (5G MOCN) sharing mode, i.e. only supports RAN sharing. For MOCNs in 5G systems, including UEs (terminals), RANs (radio access networks) and AMF (Access and Mobility Management Function) should support the ability of operators to use multiple PLMN IDs (Public Land Mobile Network ). Under the MOCN shared network architecture, the sharing of the carrier network and the sharing of the independent carrier network are divided according to whether the carrier is shared or not. When independent carriers are shared, BBU (Building Base bandUnit, indoor baseband processing unit) is shared and connected with RRU (Remote Radio Unit )/AAU (Active Antenna Unit, active antenna unit) of the same manufacturer, RRU/AAU operators are independent, each carrier is independently configured and managed, and inside a wireless side gNodeB, different logically independent cells are used for providing the multiple operators for independent use; when sharing carrier, BBU and RRU/AAU share, site side RAN equipment share, share a certain section or sections of carrier of different operators, form a continuous large bandwidth shared carrier, and further reduce cost of infrastructure and equipment.

At this time, for the multi-operator core network MOCN, when the shared carrier is used, the same cell broadcasts a plurality of PLMNs, and the UE selects one of them for registration. At this time, only the operators registered for use are seen from the UE, and the operators are not sensitive to other operators, and the spectrum resources of the operators are completely shared. When the independent carrier is used, UEs of different operators only register in the respective operator networks, which is equivalent to that spectrum resources are not shared. Therefore, the existing sharing common construction of different operators only supports high-level sharing and the bottom layer is transparent, the spectrum sharing mode among different operators is rough, the spectrum cannot be used in a refined mode, and the efficiency and the flexibility of spectrum sharing are low.

Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.

In one embodiment of the invention, a system for sharing spectrum of physical layer of co-established network of different operators is provided.

As shown in fig. 1, the inter-operator co-established network physical layer spectrum sharing system includes: the system comprises at least more than two operators, a core network corresponding to the operators and shared RAN equipment, wherein the more than two operators are in communication connection with the shared RAN equipment, and the shared RAN equipment is in communication connection with a user terminal in a shared carrier or independent carrier network sharing mode.

When at least two operators work in a shared carrier network sharing manner, as shown in fig. 2, a first part of spectrum resources pre-divided in a shared carrier are allocated to a user terminal of one of the operators for use.

As shown in fig. 3, when at least two or more operators operate in a shared manner of independent carrier networks, a second portion of spectrum resources pre-divided in the independent carrier of one operator is configured for use by a user terminal of another operator.

Specifically, for the multi-operator core network MOCN, when the shared carrier is used, the same cell broadcasts a plurality of PLMNs, the UE selects one registration thereof, only the operator registered for use is seen from the UE, the UE is insensitive to other operators, the spectrum resources of the operators are completely shared, the sharing co-construction of different operators only supports high-level sharing and the bottom layer is transparent, and if the difference of the number of users served by different operators participating in the sharing is large, the spectrum resource usage difference is also large, so for the sharing scenario of the shared carrier network, the following physical layer spectrum sharing method can be used to improve the efficiency and flexibility of spectrum sharing among different operators:

when at least more than two operators work in a shared carrier network sharing mode, dividing a first part of spectrum resources from the total spectrum resources of the shared carriers, wherein the first part of spectrum resources are configured for all user terminals or part of user terminals of a target operator meeting a first preset condition to use, and the total spectrum resources are configured for user terminals of other operators to use.

In this embodiment, for convenience of understanding, description will be made with the operator a and the operator B. As shown in fig. 4, the operator a and the operator B operate in a shared carrier network sharing manner, and both the operator a and the operator B use all bandwidths of the shared carrier without any limitation. When it appears that the operator B meets the first preset condition, all users or part of users served by the operator B are further restricted from using the first part of spectrum resources of the shared carrier. Wherein the first preset condition may be one or more of the following conditions: when fewer users are served by the operator B, or when the user service served by the operator B is a unified type service (such as a broadcast or multicast type service) or some other reason needs to limit the shared use of the partial spectrum resources, or when the priority level of the user service served by the operator B is higher, or some other reason needs to limit the exclusive use of the partial spectrum resources.

Further, in some embodiments, referring to fig. 5, a bandwidth resource of a preset size that may be divided in an FDM manner is used as the first portion of spectrum resource. The first partial spectrum resource is divided by a frequency division multiplexing method, a time division multiplexing method or a sub-band full duplex method.

It should be noted that, in this embodiment, when a part of the user terminals of the operator B are restricted to use the first part of the spectrum resources of the shared carrier, other user terminals of the operator B may still use all the shared carrier without restriction.

Further, when the first portion of spectrum resources needs to be changed according to actual requirements, the DCI or MAC CE may be dynamically configured or notification indication may be performed through RRC semi-static configuration. The total share and at most 3 first partial spectrum resource shares are indicated, for example by a 2-bit indication field, wherein the size of each first partial spectrum resource share may be predefined or determined by RRC configuration. Further, the usage mode of the first part of spectrum resources may be exclusive use or shared use with other operators, and the notification instruction may be performed through DCI, MAC CE, or RRC reconfiguration. Further, the signaling type for notifying the first part of spectrum resources is the same as the signaling type for notifying the usage of the first part of spectrum resources, for example, based on DCI notification, or based on MAC CE notification, and the signaling for notifying the first part of spectrum resources is the same as the signaling for notifying the usage of the first part of spectrum resources, for example, based on the same DCI notification of the part of spectrum resources and the usage thereof.

Further, in some embodiments, referring to fig. 6, a predetermined size of time slot resource may be divided in a TDM manner as the first portion of spectrum resource.

Specifically, when the user served by the operator B is insensitive to delay, or when the served user needs to limit the shared use of the first portion of spectrum resources for a low-capability or low-level terminal or other reasons, the served user may also be determined in a TDM manner, or when the shared use of the first portion of spectrum resources needs to be limited. Wherein, the first part of spectrum resource size can be adjusted or the total spectrum resource usage can be restored through DCI or MAC CE.

Referring further to fig. 7, when the user served by the operator B is insensitive to delay or the user served by the operator B needs to limit the exclusive use of the first portion of spectrum resources for a low-capacity or low-level terminal or other reasons, the user served by the operator a is a regular user or is sensitive to delay or when the user served by the operator a needs to limit the exclusive use of the portion of spectrum resources for a higher priority level or other reasons, the first portion of spectrum resources limited to be used by the operator B is further divided into sub-band resources (sub-band) for the user served by the operator a, and the embodiment determines the first portion of spectrum resources based on the SBFDM (sub-band FDM) mode. The first part of spectrum resources can be configured through RRC, or indicated through DCI or MAC CE, and the first part of spectrum resources can be adjusted in size or the total spectrum resources can be recovered for use through DCI or MAC CE.

Specifically, for the multi-operator core network MOCN, when independent carriers are used, UEs of different operators will only register in the respective operator networks, which is equivalent to no sharing of spectrum resources. I.e. the same cell only broadcasts one PLMN, the UE belonging to that operator will choose to register. At this time, only the operators registered for use are seen from the UE, and the operators are insensitive to other operators, and the spectrum resources of the operators are completely independent. At this time, the sharing common establishment of different operators only supports high-level sharing, the bottom layer is transparent, and at this time, carriers among different operators are independently configured and managed, and the inside of the wireless side gNodeB is provided for a plurality of operators to be independently used by using different logically independent cells. At this time, if the difference of the number of users served by different operators participating in sharing is large, the difference of the spectrum resource usage rate will also be large, so for the sharing scenario of the independent carrier network, the following physical layer spectrum sharing method can be used to improve the efficiency and flexibility of spectrum sharing among different operators:

when at least more than two operators work in an independent carrier network sharing mode, second part of spectrum resources are divided from first independent spectrum resources of first independent carriers corresponding to a first operator, and the second part of spectrum resources are configured to user terminals of second operators meeting second preset conditions for use.

Specifically, as shown in fig. 8, the carrier a and the carrier B operate in a shared manner of independent carrier networks, and each of the carrier a and the carrier B uses all bandwidths of the respective independent carriers without any limitation. When it appears that operator a meets the second preset condition, all or part of the users served by operator a are further expanded to use the second part of the spectrum resources of the independent carrier of operator B. The second preset condition includes at least one of the following conditions: when there are more subscribers served by the carrier a, or when the subscriber service served by the carrier a is a large data volume service (e.g. real-time game service, time-frequency monitoring real-time backhaul service) or other reasons, the second portion of spectrum resources of the independent carrier of the carrier B co-established therewith needs to be used in an enlarged manner, or when the priority level of the subscriber service served by the carrier a is high, or other reasons, the second portion of spectrum resources of the independent carrier of the carrier B co-established therewith needs to be used in an enlarged manner. And, the second portion of spectrum resources is used in a secondary cell (SCell) addition manner. As shown in fig. 9, the operation of adding the second partial spectrum resource as the SCell for all users or part of users served by the operator a may be configured through RRC or indicated through DCI or MAC CE. Further, the second partial spectrum resource size corresponding to the SCell may be configured by RRC, or indicated by DCI or MAC CE.

Further, all or part of the users of operator B may still use the entire available shared bandwidth of the independent carrier.

Further, when the usage of the second portion spectrum resource changes, notification instruction is performed through DCI, MAC CE, or RRC reconfiguration. The at most 4 sizes of second partial spectrum resources are indicated, for example, by a 2-bit indication field, wherein the size of each second partial spectrum resource may be predefined or determined by an RRC configuration. Further, the second part of spectrum resources with one size are all the resources of the independent carrier of the operator B, that is, the second part of spectrum resources can be shared and used by the operators. Further, for whether the second portion of spectrum resources are used in a single-shared manner or shared with other operators, the notification indication may be performed through DCI or MAC CE or RRC reconfiguration. For example, as shown in fig. 10, when used exclusively, the individual carriers of the original carrier B are limited to spectrum resources other than the second portion of spectrum resources.

Further, the signaling type for notifying the second partial spectrum resource addition is the same as the signaling type for notifying the usage of the second partial spectrum resource corresponding to the second partial spectrum resource, for example, both based on DCI notification or both based on MAC CE notification. Further, the signaling for notifying the SCell addition is the same as the signaling for notifying the usage of the second partial spectrum resource corresponding to the SCell, and for example, the partial spectrum resource and the usage thereof are notified based on the same DCI.

Similarly, when fewer users served by the operator B occur, or when the user service served by the operator B is a unified type service (such as a broadcast or multicast type service) or other reasons require restricting the use of the second portion of spectrum resources of the independent carrier, or when the priority level of the user service served by the operator B is higher or other reasons require restricting the exclusive use of the second portion of spectrum resources, all users or portions of users served by the operator B are further restricted from using the second portion of spectrum resources of the independent carrier of the operator a, and all users or portions of users served by the operator a are further expanded to use the remaining portion of the portion of spectrum resources used by the operator B, and are used in an SCell adding manner.

Further, in some embodiments, data may be transmitted by using spectrum resources of different operators through user aggregation, so as to improve efficiency and flexibility of spectrum sharing between different operators. Specifically, the method comprises the following steps:

when at least more than two operators work in an independent carrier network sharing mode, the first user terminal of the first operator is paired with the second user terminal of the second operator, and the first user terminal and the second user terminal are in communication connection according to a preset communication mode.

When uplink data is sent to a first operator, the first user terminal splits the uplink data into first uplink sub-data and second uplink sub-data, the first uplink sub-data is uploaded to the shared RAN equipment through a first independent carrier, the second uplink sub-data is sent to a paired second user terminal through a preset communication mode, the second user terminal uploads the second uplink sub-data to the shared RAN equipment through a second part of spectrum resources, and the shared RAN equipment combines the first uplink sub-data and the second uplink sub-data into uplink data.

When downlink data is sent to a first user terminal, the shared RAN equipment splits the downlink data into first downlink sub-data and second downlink sub-data, sends the first downlink sub-data to the first user terminal through a first independent carrier, sends the second downlink sub-data to a second user terminal through a second part of spectrum resources, sends the second downlink sub-data to the first user terminal through a preset communication mode, and the first user terminal combines the first downlink sub-data and the second downlink sub-data into the downlink data.

Specifically, as shown in fig. 11, the carrier a and the carrier B operate in a shared manner of independent carrier networks, and without any limitation, the carrier a and the carrier B each use all bandwidths of the independent carriers, and users served by the respective carriers are not felt. When there are more subscribers served by the operator a, or when the subscriber service served by the operator a is a large data volume service (such as a real-time game service, a time-frequency-monitored real-time backhaul service) or other reasons require to enlarge the use of all or part of spectrum resources of the independent carrier of the operator B shared therewith, or when the subscriber service served by the operator a has a higher priority level or other reasons require to enlarge the use of all or part of spectrum resources of the independent carrier of the operator B shared therewith, all or part of subscribers served by the operator a are allowed to use all or part of spectrum resources of the independent carrier of the operator B by means of user aggregate transmission. Paired users configuring operator B will be given for all or part of the users served by operator a. The operation of the user served by operator a to configure the paired user of operator B may be configured by RRC, or indicated by DCI or MAC CE. Further, the second spectrum resource used by the paired user for user aggregate transmission is not greater than the spectrum resource of the independent carrier of the operator B, and the size of the spectrum resource specifically used may be configured by RRC, or indicated by DCI or MAC CE.

For example, for downlink data transmission, in the shared RAN device, data of the user 1 served by the operator a is distributed to the higher layer or physical layer of the user 2 served by the operator B through the higher layer or physical layer, the user 2 and the user 1 are paired users, and further spectrum resources used by the paired users in aggregation transmission are part of spectrum resources of independent carriers of the operator B, and further the part of spectrum resources may be configured through RRC, or indicated through DCI or MAC CE. And user 2 forwards the data to user 1. And the user 1 receives the downlink large data traffic. Further, the data forwarded to the user 1 by the user 2 may be through bluetooth, WIFI or a preset communication mode from related devices to devices.

For example, for uplink data transmission, the shared RAN device independently schedules or group schedules data of the user 1 served by the operator a and data of the user 1 forwarded to the higher layer or physical layer of the user 2 served by the operator B through the higher layer or physical layer, i.e. the uplink data traffic has the user 1 forwarded to the paired user 2 in advance or in real time. Further, the data forwarded to the user 2 by the user 1 may be through bluetooth, WIFI or a preset communication mode from related devices to devices. After receiving the scheduling information, the two users send uplink data to the shared RAN equipment in the independent carriers according to the scheduling instruction, and the spectrum resources used by the further paired users in the aggregation transmission are second part of spectrum resources of the independent carriers of the operator B. And the shared RAN equipment receives the data in the independent carriers and then performs merging, namely the user 1 completes the uplink big data service transmission through user aggregation transmission, and the shared RAN equipment completes the big data service reception of the user 1.

Further, all or part of the users of operator B may still use the entire available shared bandwidth of the independent carrier.

Further, when the usage of the second portion spectrum resource changes, notification instruction is performed through DCI, MAC CE, or RRC reconfiguration. The at most 4 sizes of second partial spectrum resources are indicated, for example, by a 2-bit indication field, wherein the size of each second partial spectrum resource may be predefined or determined by an RRC configuration. Further, the second part of spectrum resources with one size are all the resources of the independent carrier of the operator B, that is, the second part of spectrum resources can be shared and used by the operators.

According to the inter-operator co-established network physical layer spectrum sharing system, for different operators, when the operators work in a shared carrier network sharing mode, part of spectrum resources are divided from spectrum resources corresponding to shared carriers for one operator to use, and when the operators work in an independent carrier network sharing mode, part of spectrum resources are divided from spectrum resources of independent carriers corresponding to one operator for the other operator to use, so that the shared carriers or independent carriers are used finely, and the efficiency and flexibility of spectrum sharing among the different operators are improved.

The technical features of the above embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The foregoing examples only represent preferred embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the invention. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application.
