Description

[0002] With the large-scale deployment of 5G networks and the continuous growth of their services, the energy consumption of base stations and terminal devices has become increasingly prominent. The cell-level discontinuous transmission (DTX) / discontinuous reception (DRX) technology can save energy by periodically shutting down the transmission and reception of data services. The cell-level DTX / DRX is synchronized with the terminal. By informing the terminal of the cell shutdown period, when the cell shuts down transmission and reception, the terminal stops sending and receiving at the same time, which can help the terminal save energy and further optimize the overall energy efficiency of the 5G network and reduce power consumption.

[0003] Unlike terrestrial communications, energy saving is particularly important for non-terrestrial networks (NTN). However, the current protocol only supports cell-level DTX / DRX, which cannot meet the service coverage and energy saving requirements of different NTN beams in multi-beam NTN scenarios.

[0004] Therefore, the current NTN communication technology has the problem of not supporting beam-level DTX / DRX. Summary of the invention

[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] The non-terrestrial network communication method provided in the embodiment of the present application can be applied to Figure 1In the application environment shown. Among them, the base station 102 is deployed on the satellite and communicates with the terminal 104 deployed on the ground through the NTN network. The service beam in the NTN cell can be one or more NTN beams, which can be but not limited to the synchronization signal block (SSB) beam. There can be one or more terminals 104 within the coverage of each NTN beam. Among them, the terminal (User Equipment, UE) can be but not limited to various personal computers, laptops, smart phones, tablets, Internet of Things devices and portable wearable devices. The Internet of Things devices can be smart speakers, smart TVs, smart air conditioners, smart car devices, projection devices, etc. Portable wearable devices can be smart watches, smart bracelets, head-mounted devices, etc. The head-mounted devices can be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, etc. The base station can be but not limited to various satellite LTE base stations (Enhanced Node B, eNB), 5G base stations (the next Generation Node B, gNB), etc.

[0031] In an exemplary embodiment, Figure 2 As shown, a non-terrestrial network communication method is provided, and the method is applied to Figure 1 Taking the base station 102 in the example as an example, the method includes the following steps:

[0032] Step S202, determining beam configuration information of a non-terrestrial network NTN beam.

[0033] The beam configuration information may be the DTX / DRX parameters configured for the NTN beam.

[0034] In a specific implementation, the base station may configure DTX / DRX parameters for the NTN beam, and obtain beam configuration information according to the NTN beam and its corresponding DTX / DRX parameters.

[0035] In practical applications, for each NTN beam serving in the NTN cell, the gNB can flexibly configure DTX / DRX parameters for it according to the service requirements carried by the NTN beam. The DTX / DRX parameters may include, but are not limited to, the active period, start offset, time slot offset, configuration type, activation status, etc. of DTX / DRX. Among them, the active period may be a transmission period in DTX or a reception period in DRX. The start offset may be an offset of the DTX / DRX cycle relative to the start frame. The time slot offset may be an offset of the DTX / DRX active period relative to the start time of the DTX / DRX cycle. The configuration type may be used to indicate that only DTX, only DRX, or DTX and DRX are executed jointly. The activation status may be used to indicate whether the DTX / DRX function is activated. The gNB may also determine the beam identifier of each NTN beam and the configuration identifier of the DTX / DRX parameter configuration corresponding to each NTN beam, and obtain the beam configuration information according to the beam identifier and its corresponding configuration identifier.

[0036] Step S204, sending beam configuration information to the terminal within the coverage of the NTN beam, so that the terminal performs discontinuous communication according to the received beam configuration information; the discontinuous communication includes at least one of discontinuous transmission and discontinuous reception.

[0037] In a specific implementation, the base station can send beam configuration information to the terminal within the coverage of the NTN beam. The terminal can obtain the DTX / DRX parameters corresponding to the NTN beam based on the received beam configuration information, and activate or deactivate discontinuous communication based on the DTX / DRX parameters.

[0038] In actual applications, the gNB can send the beam configuration information to the UE in the wave position corresponding to the NTN beam through the downlink control information (Downlink Control Information, DCI). The UE identifies the beam identifier of the NTN beam corresponding to itself in the received beam configuration information, and obtains the configuration identifier corresponding to the beam identifier, obtains the DTX / DRX parameter configuration of the NTN beam corresponding to itself according to the configuration identifier, and activates or deactivates the DTX / DRX function according to the DTX / DRX parameter configuration. It should be noted that the NTN beam configuration information can be sent to the UE in the corresponding wave position through DCI format 2_9.

[0039] The above-mentioned non-terrestrial network communication method determines the beam configuration information of the NTN beam and sends the beam configuration information to the terminal within the coverage of the NTN beam, so that the terminal performs discontinuous communication according to the received beam configuration information; the DTX / DRX function of each NTN beam in the NTN cell can be configured at the beam level, so that each terminal under each NTN beam can flexibly activate or deactivate the DTX / DRX function according to the beam level configuration, and realize beam-level DTX / DRX on the premise of meeting the personalized service needs of the terminal.

[0040] In an exemplary embodiment, the above step S202 may specifically include: determining a beam identifier of the NTN beam, and determining a configuration identifier of a parameter configuration corresponding to the NTN beam; and obtaining beam configuration information according to the beam identifier and the configuration identifier.

[0041] The beam identifier may be an identifier of an NTN beam, the parameter configuration may be a configuration of a beam-level DTX / DRX parameter, and the configuration identifier may be an identifier of a configured beam-level DTX / DRX parameter.

[0042] In a specific implementation, the base station can determine the beam identifier of the NTN beam, and after configuring the DTX / DRX parameters for the NTN beam, can also determine the corresponding configuration identifier, and obtain the beam configuration information based on the beam identifier and its corresponding configuration identifier.

[0043] For example, suppose the NTN beam serving the NTN cell has SSB 0 、SSB 1 、SSB 2 、SSB 3 , 2-bit information can be used as beam identifier, recorded as 00, 01, 10, 11 respectively; assuming that the DTX / DRX parameter configuration has 4 sets of parameter instances, 2-bit information can also be used as the configuration identifier, for example, 00 represents parameter instance 1, 01 represents parameter instance 2, 10 represents parameter instance 3, and 11 represents parameter instance 4, assuming SSB 0 Configuration parameter example 1, for SSB 1 Configuration parameter example 2, for SSB 2 Configuration parameter example 3, for SSB 3 Configuration parameter example 4, combining the beam identifier with the configuration identifier and sending it to the UE through DCI format 2_9, can notify the UE of the DTX / DRX parameter configuration used by each NTN beam. For example, if the UE receives 0000, it can know that the current NTN beam is SSB 0 , the DTX / DRX parameter configuration used is parameter instance 1. If the UE receives 0101, it can be known that the current NTN beam is SSB 1, the DTX / DRX parameter configuration used is parameter instance 2. If the UE receives 1010, it can be known that the current NTN beam is SSB 2 , the DTX / DRX parameter configuration used is parameter instance 3. If the UE receives 1111, it can be known that the current NTN beam is SSB 3 The DTX / DRX parameter configuration adopted is parameter instance 4. It can be seen that the UE can determine the NTN beam to which it belongs and the corresponding DTX / DRX parameter configuration according to the received beam identifier and configuration identifier, and activate or deactivate the DTX / DRX function according to the parameter configuration.

[0044] In this embodiment, by determining the beam identifier of the NTN beam and the configuration identifier of the parameter configuration corresponding to the NTN beam, the beam configuration information is obtained according to the beam identifier and the configuration identifier, and the beam-level DTX / DRX configuration can be notified to the terminal in the wave position corresponding to the NTN beam, thereby realizing flexible beam-level configuration of DTX / DRX.

[0045] In an exemplary embodiment, the above-mentioned step of determining the configuration identifier of the parameter configuration corresponding to the NTN beam may specifically include: determining the parameter configuration of the NTN beam according to the service requirements of the terminals within the coverage range of the NTN beam; and obtaining the configuration identifier according to the parameter configuration.

[0046] The service demand may be a demand for the amount of data service that needs to be sent or received.

[0047] In a specific implementation, the base station can determine the terminal service demand under the NTN beam according to the sum of the buffered data volume of the uplink and downlink scheduling requested by each terminal in the wave position corresponding to the NTN beam, and select the DTX / DRX parameter configuration that can meet the service demand from the predetermined parameter configuration list as the parameter configuration of the NTN beam. The parameter configuration list can also record the identifier corresponding to each DTX / DRX parameter configuration, and the base station can use the identifier of the selected DTX / DRX parameter configuration as the configuration identifier. Among them, the predetermined parameter configuration list can be solidified by the base station based on previous data.

[0048] For example, refer to Figure 1 , there are 3 SSBs in the NTN cell: beam SSB 1 、SSB 2 、SSB 3 , among which, SSB 1 There are two UE1 and UE2 with high data traffic demand under the beam coverage, SSB 2 There are two UE3 and UE4 with low data traffic demand under the beam coverage, SSB 3There is a UE5 with no data traffic demand under the beam coverage. 1 , the gNB can configure a set of DTX / DRX parameters with the shortest sleep duration, moderately save energy while meeting business needs, or choose not to activate DTX / DRX to maximize business needs. For example, the gNB can select parameter instance 2 in the parameter configuration list, and the parameter configuration list records its identifier as 01, then the configuration identifier is 01; for SSB 2 , the gNB can configure a set of DTX / DRX parameters with a longer sleep duration to achieve beam-level energy saving while meeting data service transmission requirements. For example, the gNB can select parameter instance 3 in the parameter configuration list, and the parameter configuration list records its identifier as 10, then the configuration identifier is 10; for SSB 3 , the gNB can configure a set of DTX / DRX parameters with the longest sleep duration to achieve the best beam-level energy saving effect. For example, the gNB can select parameter instance 3 in the parameter configuration list, and the parameter configuration list records its identifier as 11, then the configuration identifier is 11.

[0049] In this embodiment, the parameter configuration of the NTN beam is determined according to the business needs of the terminals within the coverage area of ​​the NTN beam. The configuration identifier is obtained based on the parameter configuration, and beam-level DTX / DRX configuration can be performed based on the terminal business needs to achieve optimal beam-level energy saving while meeting the business needs.

[0050] In an exemplary embodiment, the parameter configuration includes configuring at least one of an active period, a start offset, a time slot offset, a configuration type, and an activation state of the discontinuous communication.

[0051] The active period may be a transmission period in DTX or a reception period in DRX. The start offset may be an offset of the DTX / DRX cycle relative to the start frame. The time slot offset may be an offset of the DTX / DRX active period relative to the start time of the DTX / DRX cycle. The configuration type may be used to indicate whether only DTX, only DRX, or DTX and DRX are executed jointly. The activation state may be used to indicate whether the DTX / DRX function is activated.

[0052] In a specific implementation, the beam-level DTX / DRX parameters configured by the base station may include, but are not limited to, the active period of discontinuous communication, the starting offset, the time slot offset, the configuration type, and the activation status.

[0053] In practical applications, the beamDTX-DRX-ConfigList field of the beam-level DTX / DRX configuration list may be set. The beamDTX-DRX-ConfigList field may contain multiple sets of parameter information, for example:

[0054] beamDTX-DRX-onDurationTime: indicates the active period of the beam-level DTX / DRX cycle. The UE monitors the Physical Downlink Control Channel (PDCCH) only during this duration. The value is expressed in multiples of 1 / 32 milliseconds (sub-milliseconds) or milliseconds (milliseconds). For the latter, the value ms1 corresponds to 1 millisecond, the value ms2 corresponds to 2 milliseconds, and so on.

[0055] beamDTX-DRX-CycleStartOffset: indicates the beam-level DTX-DRX cycle (expressed in milliseconds), and the beam-level DTX-DRX start offset (expressed in multiples of 1 millisecond);

[0056] beamDTX-DRX-SlotOffset: beam-level DTX / DRX slot offset, used to indicate the offset of the start time of the DTX / DRX active period relative to the start of the DTX / DRX cycle, expressed in 1 / 32 milliseconds, with a value of 0 corresponding to 0 milliseconds, a value of 1 corresponding to 1 / 32 milliseconds, a value of 2 corresponding to 2 / 32 milliseconds, and so on;

[0057] beamDTX-DRX-ConfigType: indicates whether the beam-level configuration is for DTX only, or for DRX only, or for joint DTX and DRX;

[0058] beamDTX-DRX-ActivationStatus: Initial activation status of beam level DTX / DRX, indicating whether the UE should activate the configuration according to the received parameters.

[0059] In this embodiment, the parameter configuration includes configuring at least one of the active period, starting offset, time slot bias, configuration type and activation status of the discontinuous communication, so that the parameter configuration information of the beam-level DTX / DRX is more comprehensive and rich, ensuring the reliable implementation of beam-level DTX / DRX.

[0060] In an exemplary embodiment, the above-mentioned non-terrestrial network communication method may further specifically include: sending a predetermined parameter configuration list to the terminal; the parameter configuration list includes at least one candidate parameter configuration.

[0061] The parameter configuration list may be a list consisting of one or more groups of DTX / DRX parameters configured for the NTN beam. The candidate parameter configuration may be a group of DTX / DRX parameters configured for the NTN beam.

[0062] In the specific implementation, the base station can configure one or more groups of DTX / DRX parameters for the NTN beam, form a parameter configuration list, and send the parameter configuration list to the terminal. After determining the beam configuration information of the NTN beam and sending the beam configuration information to the terminal, the terminal can determine the DTX / DRX parameter configuration corresponding to the beam configuration information according to the parameter configuration list, and activate or deactivate the DTX / DRX function accordingly.

[0063] It should be noted that the parameter configuration list may also include a configuration identifier corresponding to each candidate parameter configuration. The terminal reads the configuration identifier in the beam configuration information, searches for the candidate parameter configuration corresponding to the configuration identifier in the parameter configuration list, and determines the found candidate parameter configuration as the DTX / DRX parameter configuration corresponding to the beam configuration information.

[0064] In actual applications, the beamDTX-DRX-ConfigList (beam-level DTX / DRX configuration list) field can be added to the structure ServingCellConfigCommon (serving cell configuration information). The beamDTX-DRX-ConfigList field is used to indicate one or more groups of beam-level DTX / DRX parameters for configuring the current serving beam. The beamDTX-DRX-ConfigList field is the beam configuration list. The gNB can broadcast ServingCellConfigCommon to the UE.

[0065] In this embodiment, by sending a predetermined parameter configuration list to the terminal, the terminal can find the corresponding parameter configuration in the parameter configuration list according to the received configuration identifier, thereby improving the transmission efficiency of the parameter configuration.

[0066] In an exemplary embodiment, the above step S204 may specifically include: sending beam configuration information to the terminal through DCI format 2_9.

[0067] In specific implementation, the base station can send beam configuration information to the terminal through DCI format 2_9. For example, the gNB can send the beam configuration information to the SSB by carrying 0000 in DCI format 2_9. 0 UE within the corresponding wave position.

[0068] In this embodiment, beam configuration information is sent to the terminal through DCI format 2_9, and DCI format 2_9 adopted by the current cell-level DTX / DRX can be reused to avoid defining additional DCI formats; moreover, it is convenient to simultaneously process cell-level DTX / DRX parameters and beam-level DTX / DRX parameters.

[0069] In order to facilitate those skilled in the art to have a deeper understanding of the embodiments of the present application, a specific example will be described below.

[0070] This application proposes a beam energy-saving method based on NTN. The same NTN cell is served by multiple beams, and each beam can be configured with one or more groups of different beam-level DTX / DRX related parameters; the gNB can activate or deactivate the DTX / DRX function of each beam separately through DCI 2_9; within the wave position corresponding to each beam, the gNB can flexibly configure the beam-level DTX / DRX activity period according to the different service requirements of the UE, so as to achieve the system-level energy-saving effect of joint optimization of gNB and UE without affecting the terminal service.

[0071] Figure 3 A flowchart of a beam energy saving method based on NTN is provided. Figure 3 , the beam energy saving method based on NTN may include the following steps:

[0072] Step S301, the same NTN cell has multiple beam services, and each beam service can be configured with one or more different beam-level DTX / DRX related parameters;

[0073] Add the beamDTX-DRX-ConfigList field in the structure ServingCellConfigCommon. The beamDTX-DRX-ConfigList is used to indicate one or more groups of beam-level DTX / DRX parameters for configuring the current serving beam. ServingCellConfigCommon>>beamDTX-DRX-ConfigList contains one or more groups of parameter information. The corresponding IE (Information Element) is ServingCellConfigCommon>>beamDTX-DRX-ConfigList>>BeamDTX-DRX-Config.

[0074] Specifically, the specific IE structure of the above parameters is as follows:

[0075] ServingCellConfigCommon ::= SEQUENCE {

[0076] …

[0077] beamDTX-DRX-ConfigList SetupRelease { BeamDTX-DRX-ConfigList}

[0078] …} …

[0079] BeamDTX-DRX-Config List ::= SEQUENCE(SIZE(1..maxNrofBeamDTX-DRX)) OFBeamDTX-DRX-Config

[0080] Among them, ServingCellConfigCommon>>beamDTX-DRX-ConfigList>>BeamDTX-DRX-Config contains multiple sets of parameter information:

[0081] (1) beamDTX-DRX-onDurationTime: indicates the active period of the DTX / DRX cycle, during which the UE monitors the PDCCH only, expressed in multiples of 1 / 32 milliseconds (sub-milliseconds) or milliseconds (milliseconds). For the latter, the value ms1 corresponds to 1 millisecond, the value ms2 corresponds to 2 milliseconds, and so on.

[0082] (2) beamDTX-DRX-CycleStartOffset: indicates the beam-level DTX-DRX cycle (expressed in milliseconds) and the beam-level DTX-DRX start offset (expressed in multiples of 1 millisecond).

[0083] (3) beamDTX-DRX-SlotOffset: Beam-level DTX / DRX slot offset, used to indicate the offset of the start time of the DTX / DRX active period relative to the start of the DTX / DRX cycle. The value is expressed in 1 / 32 milliseconds. A value of 0 corresponds to 0 milliseconds, a value of 1 corresponds to 1 / 32 milliseconds, a value of 2 corresponds to 2 / 32 milliseconds, and so on.

[0084] (4) beamDTX-DRX-ConfigType: Indicates whether the configuration is for beamDTX only, beamDRX only, or a joint beamDTX / DRX configuration.

[0085] (5) beamDTX-DRX-ActivationStatus: The initial activation status of beam-level DTX / DRX, indicating whether the UE should activate the configuration based on the received parameters.

[0119] Specifically, the parameter configuration principle can be as follows Figure 4 As shown, after the subframe starts, the cycle of the beam-level DTX-DRX and the starting offset relative to the start subframe (Start SFNn) are determined by beamDTX-DRX-CycleStartOffset, and then beamDTX-DRX-onDurationTimer is started for the serving cell after beamDTX-DRX-SlotOffset. The UE can monitor the PDCCH during the duration of the active period.

[0120] In step S302, the gNB can activate or deactivate the DTX / DRX function of each beam individually through DCI 2_9.

[0121] In DCI format 2_9, a bit indicating the beam index parameter field and a bit used to indicate the beam-level DTX / DRX mode (configuration identifier) ​​are added. N bits are used to indicate different SSB beam indices, and N can be {2, 4, 8, 16}; M bits are used to indicate the beam-level DTX / DRX mode selected by the UE under the corresponding beam. For example, when M=2, there are 4 groups of parameters, including 00 for the first group of instance parameters; 01 for the second group of instance parameters; 10 for the third group of instance parameters; and 11 for the fourth group of instance parameters.

[0122] Specifically, the beam index parameter bit can be configured according to the needs; the beam-level DTX / DRX mode can be configured according to the specific business and scheduling requirements; when N=2, it means that 2 bits are used to map up to 4 SSB beams, which can be respectively SSB 0 、SSB 1 、SSB 2 、SSB 3 When M=2, there are 4 groups of beam-level DTX / DRX parameter instances. Assume that the parameter beamDTX-DRX-ActivationStatus=deactivated in the first group, and the beamDTX-DRX-ActivationStatus=activated in the other three groups. The parameters beamDTX-DRX-ConfigType in the second, third, and fourth groups correspond to dtx, drx, and dtxdrx, respectively. Each SSB beam can be activated by DCI 2_9 to activate the corresponding beam-level DTX / DRX mode. Assume that SSB 0 Deactivate beam-level DTX / DRX, SSB 1 Activate beam-level DTX, SSB 2 Activate beam-level DRX, SSB 3 If beam-level DTX / DRX is activated, the configuration information is shown in Table 1 below.

[0123] Table 1 Beam index and beam-level DTX / DRX mode configuration information

[0124]

[0125] In step S303, the gNB can flexibly configure the beam-level DTX / DRX activity period according to the different UE service requirements in the beam position corresponding to each NTN beam.

[0126] Specifically, according to the actual data transmission conditions of different UEs under each SSB beam position, DCI 2_9 can be used to instruct the UE to dynamically configure different beam-level DTX / DRX activity duration periods.
