In addition, the communication system described in the embodiments of the present application is for more clearly describing the technical solution of the embodiments of the present application, and does not constitute a limitation on the technical solution provided in the embodiments of the present application, and as a person of ordinary skill in the art can know, with evolution of the network architecture and appearance of a new communication system, the technical solution provided in the embodiments of the present application is equally applicable to similar technical problems.

In a mobile communication system, a base station can perform flexible frame structure configuration according to different service scenarios. For example, for a large downlink traffic scenario, the base station may configure a large downlink frame structure (e.g., a DDDSU frame structure); the base station may configure a large uplink frame structure (e.g., DSUUU frame structure), the uplink and downlink traffic balancing scene, and the base station may configure an uplink and downlink balancing frame structure (e.g., DDSUU frame structure). Further, the base station informs the user equipment in the cell of configuring the corresponding frame structure.

However, at the starting node, the base station typically configures a large downlink frame structure for the cell. Subsequently, under the condition that the base station determines that the service scene of the cell changes, the base station cannot perceive the frame structure configuration capability of the user equipment, so that the base station cannot flexibly change into the cell configuration frame structure according to the actual service scene of the cell. Therefore, the cell network cannot exert large uplink service capacity and uplink and downlink balanced service capacity, and the cell network cannot reach the expected peak capacity.

In order to solve the above-mentioned problems in the prior art, the embodiment of the present application proposes a frame structure configuration method. As shown in fig. 5, the method includes: S501-S502.

S501, the base station acquires the number of first User Equipment (UE) supporting a target frame structure in a target cell under the condition that the frame structure of the target cell is configured as the target frame structure.

The target frame structure is any one of a large uplink frame structure, a large downlink frame structure and an uplink and downlink balanced frame structure, the duty ratio of an uplink time slot included in the large uplink frame structure is larger than the duty ratio of a downlink time slot, the duty ratio of a downlink time slot included in the large downlink frame structure is larger than the duty ratio of the uplink time slot, and the duty ratio of the downlink time slot included in the uplink and downlink balanced frame structure is equal to the duty ratio of the uplink time slot.

Illustratively, the target frame structure is exemplified as a large upstream frame structure. The base station acquires the number of the UEs supporting the large uplink frame structure in the target cell under the condition that the frame structure of the target cell is configured to the large uplink frame structure.

It should be noted that, the base station determines to configure the frame structure of the target cell as the target frame structure, and determines the target frame structure based on the service scenario.

For example, if the base station acquires that the service scenario of the current target cell is a large downlink service scenario, it is determined that the frame structure of the target cell should be configured as a large downlink frame structure.

For another example, if the base station acquires that the service scenario of the current target cell is a large uplink service scenario, it is determined that the frame structure of the target cell should be configured as a large uplink frame structure.

It can be understood that the base station obtains the number of UEs supporting the large uplink frame structure, the large downlink frame structure, and the uplink and downlink balanced frame structure in the target cell, respectively, before configuring the frame structure for the target cell.

S502, if the number of the first UE meets a preset condition, the base station sends frame structure configuration information to the UE in the target cell. Correspondingly, the UE in the target cell receives the frame structure configuration information sent by the base station.

The frame structure configuration information is used for indicating the UE in the target cell to configure the target frame structure.

As a possible implementation manner, if the number of the first UEs is greater than a preset first threshold, the base station sends frame structure configuration information to UEs in the target cell.

Illustratively, the number of first UEs is 90, and the preset first threshold is 85. The base station transmits frame structure configuration information to UEs within the target cell if it is determined that the number of first UEs 90 is greater than the preset threshold 85.

As another possible implementation manner, if the ratio of the number of the first UEs to the total number of UEs in the target cell is greater than a preset second threshold, the base station sends frame structure configuration information to the UEs in the target cell.

Specifically, the base station acquires the total number of UEs in the target cell and the number of the first UEs, and calculates a first ratio of the number of the first UEs to the total number of the UEs. Further, the base station judges the first ratio and the preset second threshold, and sends frame structure configuration information to the UE in the target cell when the first ratio is larger than the preset second threshold.

For example, taking the number of the first UEs as 90, the total number of UEs in the target cell as 100, and the preset second threshold value as 80% as an example. The base station determines the first ratio to be 90% and compares 90% to 80%. Thus, the base station transmits frame structure configuration information to UEs within the target cell if it is determined that 90% is greater than 80%.

Illustratively, the frame structure configuration information is ServingCellConfig. ServingCellConfig information element can be:

--ASN1START

--TAG-SERVINGCELLCONFIG-START

ServingCellConfig::＝SEQUENCE{

…

tdd-UL-DL-ConfigurationDedicated-Flexible-NR-r16

TDD-UL-DL-ConfigDedicated-Flexible-NR-r16 OPTIONAL,--Cond TDD

…

}

--TAG-SERVINGCELLCONFIG-STOP

--ASN1STOP。

wherein the description for ServingCellConfig can be shown in table 1 below.

Description of Table 1 ServingCellConfig

It can be appreciated that the TDD-UL-DL ConfigurationCommon configuration is added to the ServerCellConfig.

Specifically, the TDD-UL-DL ConfigurationCommon may be:

/>

wherein, for each target cell of which a large uplink frame structure, a large downlink frame structure or an uplink and downlink equalization frame structure can be configured, the base station can provide an indication of a time slot through a tdd-UL-DL-configuration-scheduled-Flexible-NR. If the base station transmits both the tdd-UL-DL-configured-explicit-NR and the tdd-UL-DL-configured-indication, the tdd-UL-DL-configured-explicit-NR will override the tdd-UL-DL-configured-configuration and provide the following functions:

-providing slot configuration by slotspecconfiguration toaddmodlist-Flexible-NR.

-for each time slot configuration.

-indicating the index number of the slot by slotIndex.

-setting the set of symbols by symbols-Flexible-NR.

-if symbols-Flexible-nr=allrown, the symbols of all slots are downlink.

-if symbols-Flexible-nr=allrollink, the symbols of all slots are uplink.

-nrofUplinkSymbols provides the number of the first downlink symbol in the slot if symbols-Flexible-nr=explicit. If neither nrofDownlinkSymbols nor nrofUplinkSymbols are empty, then there is no corresponding downlink or uplink symbol in the slot. The remaining symbols are flexible symbols, i.e., can be adjusted according to the different target frame structures.

The protocol standard defines the configuration capability of the large uplink frame structure, the large downlink frame structure or the uplink and downlink balanced frame structure, so that the network has the configuration capability of the large uplink frame structure, the large downlink frame structure or the uplink and downlink balanced frame structure (such as DDDSU, DDSUU, DSUUU).

It should be noted that, the preset first threshold and the preset second threshold are preset by the operation and maintenance personnel and stored in the base station, and the preset first threshold and the preset second threshold can be adjusted according to different target cells, and also can be adjusted in different time periods for the same target cell, which is not limited in the embodiment of the present application.

Correspondingly, after receiving the frame structure configuration information sent by the base station, the UE in the target cell configures the frame structure as a target frame structure.

Specifically, after receiving the frame structure configuration information sent by the base station, the UE in the target cell analyzes the frame structure configuration information, so as to determine that the frame structure to be configured is the target frame structure. Further, the UE in the target cell determines whether the target frame structure is supported. In the case where it is determined that the target frame structure is supported, the UE within the target cell configures the frame structure as the target frame structure. In the case that it is determined that the target frame structure is not supported, the UE within the target cell discards the frame structure configuration information or configures the frame structure as the target frame structure.

In some embodiments, the base station configures a tdd-UL-DL-configured-Flexible-NR frame structure handover message to UEs within the target cell with frame structure configuration information in the RRC reconfiguration message, the indication to cover Flexible slot portions in the tdd-UL-DL-configured configuration and the tdd-UL-DL-configured common configuration.

For example, if the UE in the target cell determines that the frame structure needs to be configured as a large uplink frame structure, the symbols-Flexible-nr=allulink of the slot indexes 3 and 4 are configured by the slot specificconfiguratotoaddmodlist-NR, the symbols-Flexible-nr=explicit of the slot index 2 is configured, the nrofDownlinkSymbols is configured as 10, and the nrofuplinksymbols is configured as 2. The UE supporting the large uplink frame structure completes the configuration of the frame structure, and the downlink symbol of the S special slot: special symbols: the uplink symbol is 10:2:2. The large upstream frame structure is illustrated in fig. 6, for example. Wherein GP is a special subframe.

For example, if the UE in the target cell determines that the frame structure needs to be configured to be up-down balanced, the symbols-Flexible-nr=allrowink of the slot index 2 is configured by the slot specificconfiguratotoaddmodlist-Flexible-NR, the symbols-Flexible-nr=allrowink of the slot index 4 is configured by the symbol-Flexible-nr=explicit of the slot index 3, the nrofDownlinkSymbols is configured to 10, and the nrofuplinksymbols is configured to 2. The UE supporting the uplink and downlink balanced frame structure completes the configuration of the uplink and downlink balanced frame structure, and at this time, the downlink symbol of the S special time slot: special symbols: the uplink symbol is 10:2:2. The large upstream frame structure is illustrated in fig. 7, for example.

For another example, if the UE in the target cell determines that the frame structure needs to be configured with a large downlink equalization frame structure, the symbols-Flexible-nr=allddown of the slot indexes 2 and 3 are configured by the slot specificconfiguratotoaddmodlist-NR, the symbols-Flexible-nr=explicit of the slot index 4 is configured, the nrofdownlinkmsymbol is configured as 10, and the nrofuplinkmsymbol is configured as 2. The UE supporting the large downlink equalization frame structure completes the configuration of the large downlink equalization frame structure, and the downlink symbol of the S special time slot: special symbols: the uplink symbol is 10:2:2. The large upstream frame structure is illustrated in fig. 8, for example.

In this embodiment, the frame structure configuration information indicates that the UE in the target cell configures slot index 2, slot index 3, and slot index 4. That is, slot index 1 and slot index 5 are fixed, specifically: symbol-Flexible-nr=allrowink for slot index 1 and symbol-Flexible-nr=allruppink for slot index 5, i.e. the frame structure is DXXXU.

In other embodiments, the base station indicates to the UE in the target cell to configure all slots through the frame structure configuration information in the RRC reconfiguration message.

For example, if the UE in the target cell determines that the frame structure needs to be configured as a large uplink frame structure, the frame structure configuration information configures the symbols-Flexible-nr=allrowink of the slot index 1, configures the symbols-Flexible-nr=allrowink of the slot index 3, the slot index 4 and the slot index 5, configures the symbols-Flexible-nr=explicit of the slot index 2, and configures the nrofDownlinkSymbols as 10, and configures the nrofuplinksymbols as 2. The UE supporting the large uplink frame structure completes the configuration of the frame structure, and the downlink symbol of the S special slot: special symbols: the uplink symbol is 10:2:2

For example, if the UE in the target cell determines that the frame structure needs to be configured to be an uplink and downlink balanced frame structure, the symbols-Flexible-nr=allddown of the slot index 1 and the slot index 2 are configured by the slot specificconfiguratotoaddmodlist-NR, the symbols-Flexible-nr=allnup of the slot index 4 and the slot index 5 are configured by the slot specificconfiguration of the slot index 3, the nrofdownlinkmsymbol is configured to 10, and the nrofuplinkmsymbol is configured to 2. The UE supporting the uplink and downlink balanced frame structure completes the configuration of the uplink and downlink balanced frame structure, and at this time, the downlink symbol of the S special time slot: special symbols: the uplink symbol is 10:2:2.

For another example, if the UE in the target cell determines that the frame structure needs to be configured with a large downlink equalization frame structure, the UE configures the slot index 1 and the symbols-Flexible-nr=allddown of the slot indexes 2 and 3 through the slot specificconffigurationtoaddmodlist-NR, configures the symbols-Flexible-nr=explicit of the slot index 4, and configures nrofdownlinksymbs as 10 and nrofuplinksymbs as 2. At this time, the base station and the UE complete configuration switching from the frame structure to the DDDSU frame structure, and downlink symbols of the S special slot: special symbols: the uplink symbol is 10:2:2.

It should be noted that, in some embodiments, the UE in the target cell discards the frame structure configuration information when it is determined that the target frame structure is not supported, so that the UE that does not support the target frame structure does not adjust the configuration of the current frame structure, and still communicates with the base station according to the frame structure configured previously. In other embodiments, in the case where the UE in the target cell determines that the target frame structure is not supported, the frame structure is configured as the target frame structure, however, the UE that does not support the target frame structure cannot be configured as the target frame structure in the end. Both the above two methods affect the uplink and downlink capacities of the target cell.

In another case, if the number of the first UEs does not meet the preset condition, the base station does not adjust the frame structure of the target cell.

As one possible implementation manner, the base station does not adjust the frame structure of the UEs in the target cell in the case that it is determined that the number of the first UEs does not meet the preset condition.

It can be understood that, in the case that the number of UEs in the target cell that do not support the target frame structure is large, if the base station configures the frame structure of the UEs in the target cell to be the target frame structure, the configuration of the frame structure of the UEs in the target cell fails, and the uplink and downlink capacities of the target cell cannot reach the expected peak capacity.

The frame structure configuration method provided by the embodiment of the application has at least the following beneficial effects: the base station can acquire the number of first User Equipments (UE) supporting the target frame structure in the target cell under the condition that the frame structure of the target cell is configured as the target frame structure. And under the condition that the number of the first UE meets the preset condition, indicating the UE in the target cell to configure the target frame structure. In this way, the base station can acquire the number of UEs supporting the target frame structure in the target cell, and instruct the UEs in the target cell to configure the target frame structure if it is determined that the number of UEs supporting the target frame structure meets the preset condition. Therefore, the frame structure of the cell can be adjusted according to the actual service scene of the cell, so that the cell network achieves the expected peak capacity.

In one design, the number of UEs supporting the large uplink frame structure, the large downlink frame structure, and the uplink and downlink equalization frame structure within the target cell may be obtained. The frame structure configuration method provided in the embodiment of the present application, as shown in fig. 9, includes: S503-S508.

S503, the base station sends capability request information to the UE in the target cell. Correspondingly, the UE in the target cell receives the capability request information sent by the base station.

As one possible implementation, the base station transmits capability request information to UEs within the target cell by broadcasting information.

In some embodiments, the capability request information broadcast by the base station further includes a frame structure detection indication identity. The frame structure detection indication mark is used for indicating the UE to report the large uplink frame structure capability, the large downlink frame structure capability and the uplink and downlink balanced frame structure capability.

S504, the UE in the target cell judges whether the configuration of the large uplink frame structure, the configuration of the large downlink frame structure or the configuration of the uplink and downlink balanced frame structure is supported.

As a possible implementation manner, after receiving the capability request information, the UE in the target cell determines whether to support the large uplink frame structure configuration, the large downlink frame structure configuration, or the uplink and downlink balanced frame structure configuration.

In some embodiments, after receiving the capability request information, the UE in the target cell parses the capability request information to determine whether the capability request information includes a flexible frame structure detection indication identifier. If the capability request information includes the flexible frame structure detection indication identifier, the UE in the target cell judges whether flexible frame structure configuration is supported.

S505, the UE in the target cell acquires the supported target frame structure configuration under the condition of judging to support the large uplink frame structure configuration, the large downlink frame structure configuration or the uplink and downlink balanced frame structure configuration.

The target frame structure is at least one of large uplink frame structure configuration, large downlink frame structure configuration or uplink and downlink balanced frame structure configuration.

S506, based on the supported target frame structure configuration, the UE in the target cell generates frame structure capability information.

Wherein the frame structure capability information includes a target flexible frame structure identification.

As a possible implementation manner, the UE in the target cell acquires the supported target flexible frame structure, and generates the target flexible frame structure identifier based on the target flexible frame structure and a preset frame structure capability protocol. Further, the UE in the target cell generates frame structure capability information according to the target flexible frame structure identifier.

Illustratively, the target frame structure is exemplified as a large downlink frame structure. And the UE in the target cell acquires the supported large downlink frame structure, and generates a target frame structure identifier (such as ul-DL-SlotFormat-MaxDOWNLink-r 17) based on the large downlink frame structure and a preset UE frame structure capability protocol. Further, the UE generates frame structure capability information based on the target frame structure identification.

It should be noted that the preset frame structure capability protocol is set in advance for the operation and maintenance personnel. Embodiments of the present application relate to modification of protocols. Among these, what is involved in this step is the definition of the UE frame structure capability protocol (TS 38.306) in the UE capability protocol. The UE frame structure capability protocol is applicable only to TDD mode and is a UE selectable capability.

Exemplary, UE frame structure capabilities are shown in table 2.

Table 2UE frame structure capability definition

Wherein, ul-DL-SlotFormat-MaxUnlink-r 17 capability represents that a large uplink transmission time slot frame structure can be configured for UE; ul-DL-SlotFormat-MaxDOWnlink-r17 capability represents configurable large downlink transmission slot frame structure for UE; the ul-DL-SlotFormat-BalancedDownlinkUpLink-r17 capability represents a slotted frame structure that enables configuration of upstream and downstream equalization for the UE.

In addition, in this step, frame structure Capability information is added to the RRC protocol definition, and the frame structure Capability information is included in the UE access stratum Capability parameter (i.e., in the Capability message UE-NR-Capability type in S302 described above).

Illustratively, the frame structure capability information may be:

/>

s507, the UE in the target cell sends the frame structure capability information to the base station. Correspondingly, the base station receives the frame structure capability information sent by the UE in the target cell.

As one possible implementation, the UE in the target cell sends capability information to the base station. Wherein the frame structure capability information is carried in the capability information.

As one possible implementation, the UE in the target cell sends frame structure capability information and capability information to the base station, respectively.

Illustratively, the capability information may be:

in another case, if the UE in the target cell does not support flexible frame structure configuration, the capability information sent by the UE in the target cell to the base station does not include frame structure capability information.

It can be understood that if the frame structure capability information is carried in the capability information, the base station acquires the frame structure capability information while acquiring the capability information, so that the number of information transmission times is reduced, and the network bandwidth resources occupied by transmitting the frame structure capability information are reduced.

S508, the base station respectively determines the number of the UEs supporting the large uplink frame structure in the target cell, the number of the UEs supporting the large downlink frame structure in the target cell and the number of the UEs supporting the uplink and downlink balanced frame structure in the target cell based on the capability information of the plurality of frame structures.

As a possible implementation manner, the base station analyzes the capability information of the plurality of frame structures one by one, obtains the number of identifiers of the large uplink frame structure, the number of identifiers of the large downlink frame structure and the number of identifiers of the uplink and downlink equalizing frames respectively, and determines the number of UEs supporting the large uplink frame structure in the target cell, the number of UEs supporting the large downlink frame structure in the target cell and the number of UEs supporting the uplink and downlink equalizing frame structure in the target cell based on the number of identifiers of the large uplink frame structure, the number of identifiers of the large downlink frame structure and the number of identifiers of the uplink and downlink equalizing frames respectively.

Illustratively, in connection with table 1, the frame structure capability information includes a large upstream frame structure identification and a large upstream frame structure identification. The base station acquires a large uplink frame structure identifier ul-DL-SlotFormat-MaxUplink-r17 and a large downlink frame structure identifier ul-DL-SlotFormat-MaxDundlink-r 17, and determines that the UE supports the large uplink frame structure and the large downlink frame structure according to the ul-DL-SlotFormat-MaxUplink-r17, the ul-DL-SlotFormat-MaxDundlink-r 17 and a preset UE frame structure capability protocol. Subsequently, the base station adds 1 to the number of UEs supporting the large uplink frame structure and 1 to the number of UEs supporting the large downlink frame structure in the target cell.

It can be appreciated that the embodiment of the present application defines a UE frame structure capability protocol, and the UE reports the frame structure capability to the base station based on the frame structure capability protocol. In this way, the base station determines the number of UEs supporting the large uplink frame structure in the target cell, the number of UEs supporting the large downlink frame structure in the target cell, and the number of UEs supporting the uplink and downlink balanced frame structure in the target cell, respectively.

In one design, to facilitate switching between a large upstream frame structure, a large downstream frame structure, and an upstream-downstream equalization frame structure. The frame structure configuration method provided in the embodiment of the present application, as shown in fig. 10, further includes: S509-S510.

S509, the base station transmits initial frame structure information to the target cell before transmitting frame structure configuration information to the target cell. Correspondingly, the UE in the target cell receives the initial frame structure information sent by the base station.

The initial frame structure information is used for indicating the UE in the target cell to configure an initial frame structure, wherein the initial frame structure comprises an uplink time slot, a time slot to be configured and a downlink time slot, the downlink time slot is positioned at the head of the initial frame structure, and the downlink time slot is positioned at the tail of the initial frame structure.

As one possible implementation manner, the base station sends initial frame structure information to the UEs in the target cell through a system broadcast message when determining that the number of UEs in an idle state or a non-active state in the target cell is greater than a third threshold.

In some embodiments, the initial frame structure information is, illustratively, tdd-UL-DL-configuration command.

the tdd-UL-DL-configuration common includes the following configuration elements:

{ frame structure configuration pattern=tdd-UL-DL-Pattern;

TDD-UL-DL-Pattern::＝SEQUENCE{

uplink-downlink transmission period = ENUMERATED { ms0p625, ms2p5}; setting of ms0p625 for FR2 band represents 0.625ms/120KHz and setting of ms2p5 for FR1Sub-6G band represents 2.5ms/30KHz (note).

Total downlink slot number = 1;

downlink symbol number=0 in non-full downlink time slot;

total uplink slot number=1;

the number of uplink symbols in the non-full uplink time slot=0;

}

}。

after receiving the tdd-UL-DL-configuration command, the UE in the target cell configures the frame structure as a DXXXU frame structure. At this time, the frame structure of the base station and the frame structure of the UE in the target cell are both configured as DXXXU frame structures, where X represents a flexible slot and a flexible symbol, D represents a full downlink symbol, and U represents a full uplink symbol.

Subsequently, if the base station determines that the service scene of the target cell is a large uplink service scene, determining that the frame structure configuration of the target cell is a large uplink frame structure configuration. Further, the base station sends frame structure configuration information to the UE in the target cell, and instructs the UE in the target cell to configure the flexible timeslots and flexible symbols in the DXXXU frame structure to DSUUU.

S510, responding to the initial frame structure information, and configuring the frame structure as the initial frame structure by the UE in the target cell.

It can be understood that, when configuring a large uplink frame structure, a large downlink frame structure or an uplink and downlink frame structure for a UE in a target cell, the base station sends initial frame structure configuration information to the UE in the target cell in advance. Therefore, when the frame structure of the UE in the target cell is switched at will, only the time slot to be configured needs to be adjusted, so that the switching among the large uplink frame structure, the large downlink frame structure and the uplink and downlink balanced frame structure is facilitated.

In one design, the target frame structure for the target cell within the target period is determined. The frame structure configuration method provided in the embodiment of the present application, as shown in fig. 11, further includes: S511-S512.

S511, the network management equipment sends the service scene prediction information to the base station. Correspondingly, the base station receives the service scene advance information sent by the network management equipment.

The service scene prediction information is used for indicating a service scene in any time period in the target cell.

As a possible implementation manner, the network management device obtains the historical service scene data of the target cell, and predicts the service scene in any period of time in the target cell based on the historical service scene data of the target cell. Further, the network management equipment generates service scene prediction information based on the service scene in any period of time in the target cell, and sends the service scene prediction information to the base station.

Exemplary, the traffic scenario prediction information may be as shown in table 3.

Table 3 traffic scene prediction information

S512, the base station acquires the service scene in the target period based on the service scene prediction information.

S513, the base station determines a target frame structure of the target cell in the target time period based on the service scene in the target time period.

Illustratively, in connection with fig. 3, the base station determines a target frame structure for the target cell within the target period. The target frame structure is shown in table 4.

TABLE 4 target frame structure within target period
