Description

Technical Field

[0001] The present invention relates to the field of non-terrestrial network communications, and in particular to a beam DTX implementation method based on a non-terrestrial network. Background Art

[0002] Cell DTX (Discontinuous Transmission) is an important energy-saving technology in communication networks. It can optimize resource utilization and reduce energy consumption by dynamically adjusting the transmission status of base stations. It has been applied in 5G networks and NTN (Non-Terrestrial Network).

[0003] In the NTN scenario, the diameter of the wave position covered by the beam of the low-orbit satellite can usually reach 50km, and a cell can be composed of one or more wave positions, so the coverage of the NTN cell is much larger than that of the terrestrial network cell. Cell DTX only supports energy saving at the cell level, and has the disadvantages of inflexible configuration and poor energy saving effect in the NTN scenario. For example, among the multiple wave positions of the NTN cell, some wave positions have frequent business data transmission, but other wave positions have only a small amount of business in progress. However, since the cell DTX configuration of each wave position in the cell is consistent and cannot be flexibly configured, cell DTX cannot achieve energy saving in this scenario. Summary of the invention

[0004] In order to solve at least one of the technical problems existing in the prior art to a certain extent, the object of the present invention is to provide a beam DTX implementation method, device and medium based on a non-terrestrial network.

[0005] The first technical solution adopted by the present invention is:

[0006] A beam DTX implementation method based on a non-terrestrial network introduces beam DTX based on cell DTX, comprising the following steps:

[0007] S-gNB configures different beam DTX parameters according to the actual service load of different beam positions to achieve flexible and efficient energy saving and resource optimization.

[0008] Furthermore, the S-gNB configures different beam DTX parameters according to the actual service load of different beam positions, including:

[0009] The S-gNB configures beamDTX-DRX-Config in ServingCellConfigCommon to indicate beam DTX, providing flexible DTX configuration for different beam positions in the same cell.

[0010] Among them, in ServingCellConfigCommon, beamDTX-DRX-Config is used as the SSB index of beam DTX.

[0011] Furthermore, when beamDTX-DRX-Config is not configured, cellDTX-DRX can be configured, activated and deactivated normally; when beamDTX-DRX-Config is configured, only the beam corresponding to the SSB configured in beamDTX-DRX-Config adopts DTX / DRX.

[0012] Further, the S-gNB configures beamDTX-DRX-Config in ServingCellConfigCommon to indicate beam DTX, including:

[0013] The S-gNB sends an RRC Reconfiguration message to the UE in the RRC connected state. The RRC Reconfiguration message includes ServingCellConfigCommon. The SSB index corresponding to the beam for which DTX needs to be activated is configured in ServingCellConfigCommon->beamDTX-DRX-Config.

[0014] After receiving the RRC Reconfiguration message, the UE compares the SSB index with the SSB index selected for the current access. If they are consistent, the UE stops monitoring the PDCCH during the beam DTX inactive period according to the beam DTX requirements; if they are inconsistent, the beam DTX configuration will not be activated.

[0015] Furthermore, the RRC Reconfiguration message also includes ServingCellConfig;

[0016] Configure the period and activity duration corresponding to beam DTX on ServingCellConfig->CellDTX-DRX-Config-r18, and set CellDTX-DRX-Config to dtx or dtxdrx, and CellDTX-DRX-activationStatus to activated;

[0017] Configure the starting position of the serving cell DCI Format2_9 on ServingCellConfig->positionInDCI-cellDTRX;

[0018] In ServingCellConfig->cellDTX-DRX-L1activation-r18, set it to enabled.

[0019] Furthermore, if the UE in the wave position mapped by the SSB has completed the beam DTX configuration, but the beam DTX has been deactivated; when there is less data service, the S-gNB activates the beam DTX for the wave position separately through DCI to achieve energy saving.

[0020] Further, the S-gNB activates beam DTX for the beam position separately through DCI, including:

[0021] Determine all connected UEs in the wave position mapped by the SSB;

[0022] The S-gNB sends DCI Format 2_9 via PDCCH, where the first 6 bits of the beam DTX / DRX indication correspond to the SSB index, and the configuration is consistent with the beamDTX-DRX-Config corresponding to the SSB;

[0023] The UE receives DCI format 2_9 through the start position of DCI Format 2_9.

[0024] The UE determines the beam DTX / DRX indication bit by reading the configuration of cellDTXDRXconfigType in DCI Format 2_9, and further determines the update of the DTX / DRX configuration.

[0025] Further, the UE determines the beam DTX / DRX indication bit by reading the configuration of cellDTXDRXconfigType in DCI Format 2_9, and then determines the update of the DTX / DRX configuration, including:

[0026] Compare the first 6 bits of the beam DTX / DRX indication with the SSB index selected for the current access. If the comparison is consistent, if cellDTXDRXconfigType is configured as dtxdrx, activate beam DTX when the beam DTX / DRX indication bit is 10 or 11; if cellDTXDRXconfigType is configured as dtx, activate beam DTX when the beam DTX / DRX indication bit is 1.

[0027] Furthermore, if the UE in the wave position mapped by the SSB has completed the beam DTX configuration and has been activated; when the data service increases, the S-gNB deactivates the beam DTX for the wave position separately through DCI.

[0028] Further, the S-gNB deactivates beam DTX for the beam position separately through DCI, including:

[0029] Determine all connected UEs in the wave position mapped by the SSB;

[0030] The S-gNB sends DCI Format 2_9 via PDCCH, where the first 6 bits of the beam DTX / DRX indication are consistent with the beamDTX-DRX-Config corresponding to the SSB.

[0031] The UE receives DCI format 2_9 through the start position of DCI Format 2_9.

[0032] The UE determines the beam DTX / DRX indication bit by reading the configuration of cellDTXDRXconfigType in DCI Format 2_9, and further determines the update of the DTX / DRX configuration.

[0033] The second technical solution adopted by the present invention is:

[0034] An electronic device comprises a processor and a memory, wherein the memory stores at least one instruction, at least one program, a code set or an instruction set, and the at least one instruction, the at least one program, the code set or the instruction set are loaded and executed by the processor to implement a beam DTX implementation method based on a non-terrestrial network as described above.

[0035] The third technical solution adopted by the present invention is:

[0036] A computer-readable storage medium, wherein at least one instruction, at least one program, code set or instruction set is stored in the storage medium, and the at least one instruction, at least one program, code set or instruction set is loaded and executed by a processor to implement a beam DTX implementation method based on a non-terrestrial network as described above.

[0037] The fourth technical solution adopted by the present invention is:

[0038] A computer program product or a computer program includes computer instructions stored in a computer-readable storage medium. A processor of a computer device can read the computer instructions from the computer-readable storage medium, and the processor executes the computer instructions, so that the computer device executes the above method.

[0039] The beneficial effect of the present invention is that by introducing beam DTX and accurately controlling the transmission state of the beam, the present invention can greatly reduce the energy consumption of the satellite while ensuring basic communication needs, thereby achieving significant energy-saving effects.

[0051] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0052] Terminology explanation:

[0053] DTX: Discontinuous Transmission.

[0054] DRX: Discontinuous Reception, discontinuous reception.

[0055] NTN: Non-Terrestrial Network.

[0056] SSB: Synchronization Signal Block, synchronization signal block.

[0057] S-gNB: Satellite-gNodeB, satellite base station.

[0058] UE: User Equipment.

[0059] PCI: Physical Cell Identity, physical cell identity.

[0060] RRC: Radio Resource Control.

[0061] DCI: Downlink Control Information, downlink control information.

[0062] In view of the existing technical problems, the present invention will introduce beam DTX to solve this problem. Based on cell DTX, beam DTX supports configuring separate DTX parameters for beams mapped with different SSBs (Synchronization Signal Blocks) to improve the energy-saving efficiency of satellite base stations in NTN scenarios and realize flexible configuration of DTX modes for different wave positions.

[0063] The cell DTX mentioned in the present invention refers to a network energy-saving technology introduced by 3GPP R18. The beam DTX introduced in the present invention is implemented based on the cell DTX, and the parameters of the beam DTX are also based on the cell DTX. Therefore, the original cell DTX mentioned in the present invention refers to the original implementation effect of the cell DTX based on the configuration of the cell DTX, but due to the influence of the newly introduced parameters of the present invention, the actual effect is manifested as the state of the beam DTX; the original cell DTX parameters refer to the parameters originally configured for the cell DTX implementation, but these parameters are actually used for the beam DTX implementation. In addition, since the beam DTX is implemented based on the cell DTX, in addition to the beam DTX activation and deactivation method based on DCI proposed in the embodiment of the present invention, the original cell DTX activation and deactivation method in the protocol (except through DCI) is still applicable to the activation and deactivation of cell DTX and beam DTX. For example, you can deactivate an activated cell DTX or beam DTX (CellDTX-DRX-activationStatus is set to activated) by setting CellDTX-DRX-activationStatus to deactivated; or activate an inactivated cell DTX or beam DTX (CellDTX-DRX-activationStatus is set to activated) by setting CellDTX-DRX-activationStatus to activated.

[0064] The present invention aims to introduce a beam DTX mode into NTN. In view of the problem that the configuration of cell DTX in NTN scenario is not flexible enough and the energy-saving efficiency is not high, a beam DTX implementation method based on NTN is proposed, which makes the configuration of DTX more flexible, not only has less impact on cell DTX, but also improves the energy-saving efficiency of S-gNB (Satellite-gNodeB). The method mainly includes the following contents:

[0065] (1) The S-gNB can indicate beam DTX by configuring beamDTX-DRX-Config in ServingCellConfigCommon.

[0066] In some embodiments, in ServingCellConfigCommon, beamDTX-DRX-Config is used as the SSB index of beam DTX, the upper 3 bits (b5b4b3) in beamDTX-DRX-Config indicate the group where the SSB is located, and the value range is 0-7; the lower 3 bits (b2b1b0) indicate the specific position of the group where the SSB is located, and the value range is 0-7; the SSB index used for beam DTX is 8*(4*b5+2*b4+1*b3)+(4*b2+2*b1+1*b0).

[0067] When beamDTX-DRX-Config is not configured, cellDTX-DRX can be configured, activated, and deactivated normally. When beamDTX-DRX-Config is configured, only the beam corresponding to the SSB configured in beamDTX-DRX-Config uses DTX / DRX.

[0068] (2) S-gNB can configure different beam DTX parameters according to the actual service load of different beam positions to achieve flexible and efficient energy saving and resource optimization.

[0069] (3) The S-gNB can activate or deactivate beam DTX through the beam DTX / DRX indication in DCI Format 2_9.

[0070] In some embodiments, in DCI Format 2_9, beam DTX / DRX indication is used, with a maximum of 8 bits, the first 6 bits are the same as beamDTX-DRX-Config, and except for the first 6 bits, the cell DTX / DRX indication is multiplexed.

[0071] The method of the present invention can achieve significant energy saving effects by precisely controlling the transmission state of the beam, and the beam DTX can significantly reduce the energy consumption of the satellite under the premise of ensuring basic communication needs. In addition, the introduction of beam DTX enables the system to dynamically adjust the transmission strategy according to the actual business load of different beams, which is conducive to more reasonable allocation of system resources (such as spectrum, power, etc.) according to actual needs, thereby improving resource utilization efficiency.

[0072] The above method is explained in detail below with reference to the accompanying drawings and specific embodiments.

[0073] See also Figure 1 , Figure 1 This is a schematic diagram of an applicable scenario of the present invention.

[0074] The present invention is applicable to NTN transparent load architecture and regenerative load architecture. Each S-gNB (Satellite-gNB) may include one or more cells, and each cell may provide services for one or more SSB-mapped beams. Cell DTX is already supported in the 3GPP R18 version, so the implementation method, activation method, and deactivation method of beam DTX of a single cell based on cell DTX will be focused on in the embodiments. Figure 1 In the DTX mode, beams mapped by multiple SSBs form multiple beam positions, each beam position has a different number of UEs (User Equipment), and the service loads of each beam position are not balanced. These beam positions together constitute a complete service cell, that is, they have the same PCI. In cell DTX, the cell DTX configuration of each beam position is consistent. The goal of beam DTX is to provide more flexible DTX configuration for different beam positions in the same cell to achieve energy saving.

[0075] Embodiment 1:

[0076] like Figure 1 In the example, SSB0 maps to wave position 0, which has a high service load; SSB1 maps to wave position 1, which has a moderate service load; and SSB2 maps to wave position 2, which has a low service load. The S-gNB will configure beam DTX for different wave positions to achieve energy saving. The configuration of beam DTX is as follows: Figure 2 As shown, the signaling process involved in the implementation is as follows Figure 3 As shown, the configuration process is as follows Figure 4 As shown; the following is the detailed process.

[0077] For all UEs in RRC connected state with the S-gNB:

[0078] Step 1: In the RRC Reconfiguration message pre-sent to UEs of different beam positions, the S-gNB configures the period, activity duration, etc. corresponding to beam DTX on ServingCellConfig->CellDTX-DRX-Config-r18, and sets CellDTX-DRX-Config to dtx or dtxdrx, and CellDTX-DRX-activationStatus to activated. The above configuration is the original cell DTX configuration, which is now used to implement beam DTX.

[0079] Specifically, for the wave position 0 mapped by SSB0, its service load is relatively high, the configured DTX cycle cellDTX-DRX-Cycle can be relatively short, and the beam DTX activity duration cellDTX-DRX-onDurationTimer can be relatively long. For the wave position 1 mapped by SSB1, its service load is moderate, the configured DTX cycle cellDTX-DRX-Cycle can be of medium length, and the beam DTX activity duration cellDTX-DRX-onDurationTimer can be of medium length. For the wave position 2 mapped by SSB2, its service load is relatively low, the configured DTX cycle cellDTX-DRX-Cycle can be relatively long, and the beam DTX activity duration cellDTX-DRX-onDurationTimer can be relatively short.

[0080] Step 2: In the RRC Reconfiguration message pre-sent to UEs with different beam positions, the S-gNB configures the SSB index corresponding to the beam for which DTX needs to be activated in ServingCellConfigCommon->beamDTX-DRX-Config.

[0081] Specifically, for a certain wave position mapped by SSBn, where n is the maximum number of SSBs that can be configured by the S-gNB, the upper 3 bits of the SSB index (b5, b4, b3∈{0,1}) are the binary numbers corresponding to the quotient of n divided by 7, that is, 4*b5+2*b4+1*b3=n / 7. For the lower 3 bits of the SSB index (b3, b2, b1∈{0,1}), they are the binary numbers corresponding to the remainder of n divided by 7, that is, 4*b2+2*b1+1*b0=n mod 7.

[0082] Therefore, for SSB0, the quotient of n divided by 7 is 0, so b5 = 0, b4 = 0, b3 = 0. The remainder of n divided by 7 is 0, b2 = 0, b1 = 0, b0 = 0.

[0083] For SSB1, the quotient of n divided by 7 is 0, so b5 = 0, b4 = 0, b3 = 0. The remainder of n divided by 7 is 1, b2 = 0, b1 = 0, b0 = 1.

[0084] For SSB2, the quotient of n divided by 7 is 0, so b5 = 0, b4 = 0, b3 = 0. The remainder of n divided by 7 is 2, b2 = 0, b1 = 1, b0 = 0.

[0085] Therefore, the beamDTX-DRX-Config of the beam positions mapped by SSB0, SSB1, and SSB2 should be configured as 000000, 000001, and 000010, respectively.

[0086] Step 3: The S-gNB configures the starting bit position of the serving cell DCI Format 2_9 on ServingCellConfig->positionInDCI-cellDTRX in the RRC Reconfiguration message pre-sent to the UE.

[0087] Step 4: In the RRC Reconfiguration message pre-sent to the UE, the S-gNB sets ServingCellConfig->cellDTX-DRX-L1activation-r18 to enabled.

[0088] Step 5: RRC Reconfiguration message from S-gNB to UE.

[0089] Step 6: The UE sends an RRC Reconfiguration complete message to the S-gNB.

[0090] Step 7: The UE compares the SSB index in beamDTX-DRX-Config with the SSB index selected for the current access. If they are consistent, the UE stops monitoring the PDCCH during the beam DTX inactive period according to the beam DTX requirements. If they are inconsistent, the beam DTX configuration will not be activated.

[0091] For other non-connected UEs: no impact.

[0092] Embodiment 2:

[0093] like Figure 1 In the example, the UE in the beam position 1 mapped by SSB1 has completed the beam DTX configuration, but the beam DTX has been deactivated. When there is less data traffic, the S-gNB can activate the beam DTX for this beam position separately through DCI to achieve energy saving. The signaling process involved in the beam DTX activation based on DCI is as follows: Figure 5 , the configuration process is as follows Figure 6 ; The following is the detailed process.

[0094] Step 1: Determine all connected UEs in wave position 1 mapped to SSB1:

[0095] Step 2: The S-gNB sends DCI Format 2_9 via PDCCH, where the first 6 bits of the beam DTX / DRX indicator correspond to the SSB index, and the configuration is consistent with the beamDTX-DRX-Config corresponding to SSB1. If cellDTXDRXconfigType is configured as dtxdrx, the last two bits of the beam DTX / DRX indicator are 10 or 11; if cellDTXDRXconfigType is configured as dtx, the last two bits of the beam DTX / DRX indicator are 1.

[0096] Step 3: The UE can determine the starting position of DCI Format 2_9 through the indication of positionInDCI-cellDTRX.

[0097] Step 4: The UE determines the beam DTX / DRX indication bit by reading the configuration of cellDTXDRXconfigType in DCI Format 2_9, and then determines the update of the DTX / DRX configuration.

[0098] Compare the first 6 bits of the beam DTX / DRX indication with the SSB index selected by the current access. If they are consistent, then further configure cellDTXDRXconfigType to dtxdrx, and activate beam DTX when the beam DTX / DRX indication bit is 10 or 11. Configure cellDTXDRXconfigType to dtx, and activate beam DTX when the beam DTX / DRX indication bit is 1.

[0099] Embodiment 3:

[0100] like Figure 1 In the example, the UE in the beam position 1 mapped by SSB1 has completed the beam DTX configuration and has been activated. When the data service increases, the S-gNB will deactivate the beam DTX for this beam position separately. The signaling process involved in the beam DTX deactivation based on DCI is as follows: Figure 5 , the configuration process is as follows Figure 7 ; The following is the detailed process.

[0101] Step 1: Determine all connected UEs in wave position 1 mapped to SSB1:

[0102] Step 2: The S-gNB sends DCI Format 2_9 via PDCCH, where the first 6 bits of the beam DTX / DRX indication are consistent with the beamDTX-DRX-Config corresponding to SSB1. If cellDTXDRXconfigType is configured as dtxdrx, the beam DTX / DRX indication bit is 00 or 01; if cellDTXDRXconfigType is configured as dtx, the beam DTX / DRX indication bit is 10.

[0103] Step 3: The UE can determine the starting position of DCI Format 2_9 through the indication of positionInDCI-cellDTRX to complete the deactivation of beam DTX.

[0104] Step 4: The UE determines the beam DTX / DRX indication bit by reading the configuration of cellDTXDRXconfigType in DCI Format 2_9, and then determines the update of the DTX / DRX configuration.

[0105] If the first 6 bits of the beam DTX / DRX indication are compared with the SSB index selected by the current access, if they are consistent, then further, cellDTXDRXconfigType is configured as dtxdrx, and the beam DTX / DRX indication bit is 00 or 01, the beam DTX is deactivated. When cellDTXDRXconfigType is configured as dtx, and the beam DTX / DRX indication bit is 0, the beam DTX is deactivated.

The method for implementing beam DTX based on a non-terrestrial network according to claim 7, characterized in that: The UE determines the beam DTX / DRX indication bit by reading the configuration of cellDTXDRXconfigType in DCI Format 2_9, and then determines the update of the DTX / DRX configuration, including: Compare the first 6 bits of the beam DTX / DRX indication with the SSB index selected for the current access. If the comparison is consistent, if cellDTXDRXconfigType is configured as dtxdrx, activate beam DTX when the beam DTX / DRX indication bit is 10 or 11; if cellDTXDRXconfigType is configured as dtx, activate beam DTX when the beam DTX / DRX indication bit is 1.

9. The method for implementing beam DTX based on a non-terrestrial network according to claim 1, characterized in that: If the UE in the wave position mapped by the SSB has completed the beam DTX configuration and has been activated; when the data service increases, the S-gNB deactivates the beam DTX for this wave position separately through DCI.

10. A method for implementing beam DTX based on a non-terrestrial network according to claim 9, characterized in that: The S-gNB deactivates beam DTX for the beam position separately through DCI, including: Determine all connected UEs in the wave position mapped by the SSB; S-gNB sends DCI Format 2_9 via PDCCH; The UE receives DCI format 2_9 through the start position of DCI Format 2_9. The UE determines the beam DTX / DRX indication bit by reading the configuration of cellDTXDRXconfigType in DCI Format 2_9, and further determines the update of the DTX / DRX configuration.
