Description

Technical Field

[0001] This invention relates to the field of wireless communication, and more particularly to a DTX / DRX configuration method, apparatus, device, storage medium, and program product. Background Technology

[0002] DTX (Discontinuous Transmission) and DRX (Discontinuous Reception) are important technologies in wireless communication used to save power consumption in terminals (such as mobile phones and IoT devices) and improve network efficiency. DTX and / or DRX configuration information refers to a series of parameters and rules set to control the transmitting and receiving behavior of terminals.

[0003] However, the inventors discovered that existing technologies have at least the following problems: Existing DTX and DRX configurations are at the cell level. For multi-beam hopping scenarios in NTN (Non-Terrestrial Network), terminals may switch between different satellites or satellite beams, and the propagation conditions, coverage areas, and service requirements of each beam may differ. Therefore, adopting a uniform cell-level configuration may not fully meet actual needs, thus affecting system performance and power efficiency. Summary of the Invention

[0032] And / or,

[0033] When the feedback information is a second feedback information indicating that the DTX and / or DRX activation time is configured too short, the configuration of the DTX and / or DRX activation time is extended.

[0040] And / or,

[0041] When it is determined that there is still data transmission and reception, and the DTX and / or DRX activation time has ended, a second feedback message indicating that the DTX and / or DRX activation time is configured too short is generated.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0062] See Figure 1This is a flowchart illustrating a DTX and / or DRX configuration method provided by an embodiment of the present invention. The embodiment of the present invention provides a DTX and / or DRX configuration method applied to the network side, and the method includes step S11:

[0063] S11. Transmit configuration information for discontinuous transmission DTX and / or discontinuous reception DRX at the cell level and / or beam level.

[0064] In this embodiment of the invention, compared to existing DTX and / or DRX configurations at the cell level, this embodiment configures DTX and / or DRX configuration information at the beam level on the network side, without restricting the active, idle, and inactive states of RRC in 5G / NR. The network side sends the configured beam-level DTX and / or DRX configuration information to the terminal side, enabling the terminal side to receive and / or transmit data according to the beam-level DTX and / or DRX configuration information.

[0065] By employing the technical means of this invention, the network side configures and sends beam-level DTX and / or DRX configuration information to the terminal side. This enables the terminal to select the appropriate beam-level DTX and / or DRX configuration information for data transmission and reception control when switching between different satellites or satellite beams, based on the currently located satellite beam. This allows for more precise control of the terminal's transmission and reception behavior under different beams, effectively solving the problem that existing cell-level DTX and / or DRX configuration information is not well-suited for NTN multi-beam hopping scenarios. This invention enhances the DTX and / or DRX mechanism for NTN multi-beam hopping scenarios, effectively meeting actual communication needs, improving NTN system performance, and reducing system power consumption.

[0066] As a preferred embodiment, the present invention further improves and optimizes the process of transmitting beam-level DTX and / or DRX configuration information on the network side based on the above embodiments.

[0067] In the first preferred embodiment, step S11, namely the configuration information of the transmit beam level DTX and / or DRX, includes:

[0068] Configure and send the DTX and / or DRX configuration information of the satellite beam directly.

[0069] In this embodiment of the invention, the network side directly configures the DTX and / or DRX configuration information of each satellite beam according to the service requirements and propagation conditions of each satellite beam, forming the DTX and / or DRX configuration information at the beam level, and sends it to the terminal side for data transmission and reception.

[0070] Preferably, the configuration information of DTX and / or DRX includes at least one of the following:

[0071] DTX and / or DRX configuration parameters, satellite identifier or satellite beam identifier, SSB reference signal index (SSBindex), DTX and / or DRX configuration parameter index, indication information on whether the upcoming serving cell or beam uses the same DTX and / or DRX configuration parameters as the current serving network node, mapping relationship between DTX and / or DRX configuration parameters and SSB reference signal (NRbeam), beam position transition information, and indication information on whether DTX and / or DRX configuration parameters are active;

[0072] The DTX and / or DRX configuration parameters include at least one of the following: DTX and / or DRX activation time (onDurationTimer), DTX and / or DRX cycle, DTX and / or DRX start offset (startoffset), DTX and / or DRX slot offset (slot offset), DTX and / or DRX type (config type), and DTX and / or DRX activation status (activationStatus).

[0073] The DTX and / or DRX cycle represents the duration of the DTX and / or DRX cycle, i.e., the period during which the terminal device switches between active and dormant states. The activation time (onDurationTimer) represents the time the terminal device remains active within the DTX and / or DRX cycle. The cycle and activation time in the DTX / DRX configuration parameters need to consider waveform state information and waveform state duration. The network side directly configures the parameters or defines specific calculation formulas in the protocol, and the terminal calculates according to the formulas based on the auxiliary information provided by the network side.

[0074] Optionally, the DTX and / or DRX periods can be calculated based on the sum of the durations of each state in the state transition combination of the satellite beam.

[0075] For example, different beam states N3, N2, and N1 can be set. These states may reflect beam activity, priority, transmission quality, or other network-related metrics. The duration of a beam state refers to the length of time each state lasts.

[0076] The specific cycle deduction is: p = N3 + N1, N2 + N1, N3 + N2 + N1.

[0077] That is, if the current state is N3 followed by state N1, the period may be the sum of the durations of states N3 and N1 (N3+N1). Similarly, if the state sequence is N2, N1 or N3, N2, N1, the period will be adjusted accordingly.

[0078] In one alternative implementation, the DTX and / or DRX activation time can be calculated based on the duration of the state before and after the satellite beam undergoes a state transition.

[0079] As an example, a specific activation time projection:

[0080] onDurationTimer = N3(+N2), N3 <-> N2 conversion;

[0081] onDurationTimer = N3 or N2, N3->N1 conversion or N2->N1 conversion.

[0082] That is, if the state transitions from N3 to N2, the activation time may be set to N3 (possibly plus part or all of N2, depending on the specific implementation). If the state transitions from N3 or N2 to N1, the activation time may be set to the duration of N3 or N2.

[0083] In another optional implementation, after configuring and / or calculating the DTX and / or DRX activation time onDurationTimer, a preset activation time inactive timer is added. That is, the DTX and / or DRX activation time can be calculated based on the sum of the original activation time and the preset activation time adjustment value.

[0084] Specifically, see Figure 2 This is a schematic diagram illustrating the principle of DTX and / or DRX activation time in an embodiment of the present invention. A new activation time, inactive timer, is introduced to extend the activation time based on the activation time onDurationTimer.

[0085] Understandably, this embodiment of the invention is more applicable when the waveform state transitions between N3 and N2 due to sudden service interruptions or incomplete transmission of previous services. In such cases, an inactive timer is activated after the transition to maintain the active state. For regular waveform state changes, a large onDurationTimer can be configured directly, without needing to follow the onDurationTimer with an inactive timer to achieve a longer activation time.

[0086] Preferably, the mapping relationship between the DTX and / or DRX configuration parameters and the SSB reference signal includes at least one of the following: one-to-one mapping, one-to-many mapping, and many-to-one mapping.

[0087] The following presents three configuration methods for the mapping relationship between the DTX and / or DRX configuration parameters and the SSB reference signal.

[0088] In the first configuration method, the method of configuring the mapping relationship between the DTX and / or DRX configuration parameters and the SSB reference signal includes:

[0089] The protocol predefines multiple sets of DTX and / or DRX configuration parameter sets and their corresponding DTX and / or DRX configuration parameter set indices, and configures the mapping relationship between the DTX and / or DRX configuration parameter set indices and the SSB reference signal index.

[0090] In this embodiment of the invention, the mapping relationship between the DTX and / or DRX configuration parameter set, the SSB (NR beam) index, and the DTX / DRX configuration parameter set index is defined in the protocol, as shown in the table below. Then, the network side only needs to provide the mapping relationship information between the SSB index and the DTX / DRX configuration parameter set index.

[0091] Configure a one-to-one mapping between SSB and DTX / DRX:

[0092]

[0093] Configure one-to-many mapping for SSB<->DTX / DRX:

[0094]

[0095]

[0096] Configure many-to-one mapping for SSB<->DTX / DRX:

[0097]

[0098] By employing the technical means of this invention, multiple sets of DTX and / or DRX configuration parameter sets are predefined in the protocol, and the mapping relationship between the DTX and / or DRX configuration parameter set index and the SSB reference signal index is configured. Then, the network side only needs to send the mapping relationship between the DTX and / or DRX configuration parameter set index and the SSB reference signal index, thereby reducing the amount of data transmission.

[0099] In the second configuration method, the method of configuring the mapping relationship between the DTX and / or DRX configuration parameters and the SSB reference signal includes:

[0100] Configure the mapping relationship between the DTX and / or DRX configuration parameter sets and the SSB reference signal index.

[0101] In this embodiment of the invention, no predefined parameters are specified in the protocol. The network side configures specific DTX and / or DRX configuration parameter sets, as well as the mapping relationship between the DTX and / or DRX configuration parameter sets and the SSB reference signals, and sends them to the terminal. See the table below.

[0102] Configure a one-to-one mapping between SSB and DTX / DRX:

[0103]

[0104]

[0105] Understandably, the configuration methods for one-to-many mapping and many-to-one mapping are similar, and will not be elaborated here.

[0106] Using the technical means of this invention, the network side configures the mapping relationship between specific DTX and / or DRX configuration parameter sets and SSB reference signals, and sends them to the terminal. This eliminates the need for protocol pre-definition and saves on the protocol definition process.

[0107] In the third configuration method, the method of configuring the mapping relationship between the DTX and / or DRX configuration parameters and the SSB reference signal includes:

[0108] A semi-static pre-configuration method is used to configure multiple sets of DTX and / or DRX configuration parameter sets covering the entire satellite trajectory or a specific satellite beam. The activation of one or more sets of corresponding DTX and / or DRX configuration parameter sets is indicated by RRC signaling, DCI command, or MAC CE command. The RRC signaling, DCI command, or MAC CE command includes at least one of the following information: SSB reference signal index, the index of the DTX and / or DRX configuration parameter set or the corresponding DTX and / or DRX configuration parameter set, activation indication information, satellite beam information, and activation start time information.

[0109] In this invention, multiple sets of DTX / DRX configuration parameters for the entire satellite trajectory or satellite beam coverage are pre-configured in a semi-static manner. When in use, the network side dynamically activates a certain set of configurations through RRC (Radio Resource Control) signaling, DCI (Downlink Control Information) commands, or MAC CE (Medium Access Control Element) commands.

[0110] Specifically, a common RNTI (Common Radio Network Temporary Identifier) ​​is introduced to scramble the PDCCH or MAC CE to implement DTX / DRX configuration under a specific cell or satellite beam. One DTX / DRX configuration can be activated each time, or multiple configurations can be activated at once (pre-)time.

[0111] In one implementation, see Figure 3 This is a schematic diagram of an activation method under the semi-static pre-configuration method in an embodiment of the present invention. When the method of activating one DTX / DRX configuration at a time is adopted, the RRC signaling, DCI instruction or MAC CE instruction contains SSB (NR beam) information, the corresponding DTX / DRX configuration index, and activation indication information indicating whether the DTX / DRX configuration is activated.

[0112] In another implementation, see Figure 4 This is a schematic diagram of another activation method under the semi-static pre-configuration method in the embodiments of the present invention. When multiple configurations are activated at once (pre-)time, the RRC signaling, DCI instruction or MAC CE instruction includes satellite beam information, corresponding DTX / DRX configuration index, activation indication information of whether the DTX / DRX configuration is activated, and activation start time information.

[0113] By employing the technical means of this invention, a semi-static pre-configuration combined with dynamically activated pre-configuration DTX / DRX configuration method is adopted, providing a flexible and efficient way for satellite communication systems to manage terminal scheduling and resource allocation, which helps to improve the overall performance of the system and user experience.

[0114] In the second preferred embodiment, step S11, namely transmitting the configuration information of DTX and / or DRX at the cell level and / or beam level, includes:

[0115] Send cell-level DTX and / or DRX configuration information;

[0116] Determine and / or provide DTX and / or DRX configuration parameters in the DTX and / or DRX configuration information of the satellite beam that are different from the DTX and / or DRX configuration information at the cell level, and send them as transformation parameters.

[0117] In this embodiment of the invention, the network side calculates the DTX and / or DRX configuration information of each satellite beam based on factors such as service requirements and propagation conditions. Based on the original cell-level DTX and / or DRX configuration information, it determines the DTX / DRX configuration parameters in the satellite beam's DTX / DRX configuration information that differ from the cell-level DTX / DRX configuration information, and uses these as transformation parameters. The cell-level DTX / DRX configuration information and the transformation parameters are then used as the beam-level DTX / DRX configuration information and sent to the terminal side.

[0118] Specifically, the network side utilizes existing cell-level DTX and / or DRX configuration information to provide two levels of DTX and / or DRX configuration information. The network side broadcasts / multicasts cell-level DTX and / or DRX configuration information and beam-level (satellite beam or NR beam SSB) DTX and / or DRX configuration information to refresh the configuration.

[0119] Based on the cell-level DTX and / or DRX configuration information, the network side provides different variable parameters for different satellite beams by offering DTX and / or DRX configuration information that differs from the cell-level information. These variable parameters include one or more variations in DTX and / or DRX activation time (onDurationTimer), DTX and / or DRX cycle, DTX and / or DRX start offset, DTX and / or DRX slot offset, DTX and / or DRX type (configtype), and DTX / DRX activation status (activationStatus), thereby enabling the configuration of beam-level DTX and / or DRX information for different satellite beams.

[0120] It should be noted that the specific parameters included in the configuration information of the satellite beam's DTX and / or DRX, as well as the calculation and configuration methods of each parameter, can be referred to the above embodiments, and will not be repeated here.

[0121] By employing the technical means of this invention, while the network side issues cell-level configuration, it also issues additional configuration transformation quantities for each satellite beam according to the satellite beam where the terminal is located. This enables precise control over the terminal's transmission and reception behavior under different beams with minimal changes to the existing configuration information.

[0122] For a preferred embodiment, see Figure 3This is a flowchart illustrating a preferred DTX and / or DRX configuration method according to an embodiment of the present invention. The embodiments of the present invention are further implemented based on any of the above embodiments, and the method further includes steps S12 to S13:

[0123] S12. When receiving an indication message from the terminal that supports uplink beam switching capability, determine whether to configure different DTX and DRX configuration parameters for the terminal based on the service duration of the satellite beam.

[0124] S13. Send a display indication message to the terminal indicating whether the DTX configuration parameters and the DRX configuration parameters are the same.

[0125] It should be noted that when a terminal introduces new capabilities, especially supporting uplink beamhopping (UL beamhopping), the network side does need to flexibly configure DTX and DRX. This is because uplink and downlink transmissions may be performed through different satellite beams, and the service duration of each beam may be different. Therefore, independent DTX and DRX configurations are needed to optimize resource utilization and terminal power consumption.

[0126] In this embodiment of the invention, when the terminal has the capability to support uplink beam hopping, the terminal sends an indication message to the network side indicating that it supports uplink beam hopping. Upon receiving a report from the terminal indicating support for UL beam hopping, the network side, considering that uplink and downlink transmissions may be performed via different satellite beams, needs to determine whether to configure different DTX and DRX configuration parameters for the terminal based on the service duration of the satellite beam, and informs the terminal of the corresponding result through a display indication.

[0127] In one optional implementation, the display indication information is the original cell-level DTX and / or DRX configuration indication parameters. The DTX configuration parameters and the DRX configuration parameters are indicated by updating the field interpretation of the original cell-level DTX and / or DRX configuration indication parameters.

[0128] As an example, using the existing cellDTXDRXconfigType parameter, which contains dtx, drx, and dtxdrx fields, the interpretation of these fields can be updated. For instance, configuring cellDTXDRXconfigType as dtx indicates that DRX and DTX use different configurations; configuring cellDTXDRXconfigType as dtxdrx indicates that DRX and DTX use the same configuration.

[0129] In another optional implementation, the display indication information is a newly added DTX and / or DRX configuration indication parameter, and the DTX configuration parameter and the DRX configuration parameter are the same by customizing the field interpretation of the newly added DTX and / or DRX configuration indication parameter.

[0130] As an example, a new parameter, beamDTXDRXsame, is introduced, and its specific value is customized. If it is set to true, it means that DRX and DTX use the same configuration. If it is set to false or not set, it means that DRX and DTX use different configurations.

[0131] The technical means employed in this invention have two approaches: the first utilizes existing parameters, reducing the introduction of new parameters and thus decreasing system complexity; the second approach introduces new parameters, providing clearer and more direct configuration instructions and avoiding conflicts with existing system parameters. In practical applications, the most suitable approach can be selected based on the specific needs of the system and compatibility with the existing architecture.

[0132] For a preferred embodiment, see Figure 5 The present invention is further implemented based on any of the above embodiments, and the method further includes steps S14 to S15:

[0133] S14. Receive feedback information reported by the terminal;

[0134] S15. Adjust the configuration information of DTX and / or DRX at the cell level and / or beam level according to the feedback information.

[0135] In this embodiment of the invention, after the terminal transmits and receives data according to the DTX / DRX configuration information at the beam level, it generates corresponding feedback information based on the data transmission and reception status and reports it to the network side. The network side can adjust the DTX and / or DRX configuration information at the cell level and / or beam level according to the feedback information.

[0136] As an optional implementation, the DTX / DRX configuration information includes a DTX / DRX activation time, used to instruct the terminal to transmit and receive data during the DTX / DRX activation time. Therefore, step S15, which involves adjusting the cell-level and / or beam-level DTX and / or DRX configuration information based on the feedback information, includes:

[0137] When the feedback information is a first feedback information indicating that the DTX and / or DRX activation time is configured too long, the configuration of the DTX and / or DRX activation time is shortened;

[0138] and / or;

[0139] When the feedback information is a second feedback information indicating that the DTX and / or DRX activation time is configured too short, the configuration of the DTX and / or DRX activation time is extended.

[0140] Specifically, after receiving the DTX and / or DRX configuration information from the network side, the terminal performs data transmission and reception within the corresponding activation time period. Assuming the waveform state is active, if the terminal determines that no data transmission or reception has occurred beyond a certain threshold number of times, but is still within the DTX and / or DRX activation time, it reports to the network that the corresponding DTX and / or DRX activation time (onDurationTimer) configuration is too long. The network side then adjusts the corresponding configuration information, i.e., shortens the DTX and / or DRX activation time (onDurationTimer) configuration. If the terminal determines that data transmission and reception have continued beyond a certain threshold number of times (non-burst situation), but the DTX and / or DRX activation time has ended, it reports to the network that the corresponding DTX and / or DRX activation time (onDurationTimer) configuration is too short. The network side then adjusts the corresponding configuration information, i.e., increases the DTX and / or DRX activation time (onDurationTimer) configuration.

[0141] By employing the technical means of this invention, the network side can adjust the DTX and / or DRX configuration information in real time according to the data transmission and reception status of the terminal, which is more conducive to optimizing system performance and saving terminal power consumption.

[0142] See Figure 6 This is a flowchart illustrating another DTX and / or DRX configuration method provided in an embodiment of the present invention. The present invention also provides a DTX and / or DRX configuration method applied to the terminal side, the method including step S21:

[0143] S21. Receive the configuration information of discontinuous transmission DTX and / or discontinuous reception DRX configured by the network side at the cell level and / or beam level.

[0144] In this embodiment of the invention, the network side configures and sends beam-level DTX and / or DRX configuration information to the terminal side. After receiving the cell-level and / or beam-level DTX and / or DRX configuration information, the terminal side performs data reception and / or transmission control according to the DTX and / or DRX configuration information. For example, if the DTX and / or DRX configuration information includes a DTX / DRX activation time (onDurationTimer), the terminal side performs data transmission and reception during the DTX / DRX activation time.

[0145] Furthermore, the method further includes step S22:

[0146] S22. Generate feedback information based on data transmission and reception status, and report the feedback information to the network side; wherein, the feedback information is used to instruct the network side to adjust the configuration information of DTX and / or DRX at the cell level and / or beam level.

[0147] Optionally, the feedback information includes first feedback information or second feedback information. Then, generating feedback information based on data transmission and reception includes:

[0148] When it is determined that there is no data transmission or reception, and it is still within the DTX and / or DRX activation time in the configuration information of the DTX and / or DRX, a first feedback message indicating that the DTX and / or DRX activation time is configured to be too long is generated.

[0149] and / or;

[0150] When it is determined that there is still data transmission and reception, and the DTX and / or DRX activation time has ended, a second feedback message indicating that the DTX and / or DRX activation time is configured too short is generated.

[0151] It should be noted that the DTX and / or DRX configuration method applied to the network side provided in the embodiments of the present invention corresponds one-to-one with all the process steps of the DTX and / or DRX configuration method applied to the terminal side in the above embodiments. The working principle and beneficial effects of the two are the same, so they will not be described again.

[0152] By employing the technical means of this invention, the network side configures and sends beam-level DTX and / or DRX configuration information to the terminal side. This enables the terminal to select the appropriate beam-level DTX and / or DRX configuration information for data transmission and reception control when switching between different satellites or satellite beams, based on the currently located satellite beam. This allows for more precise control of the terminal's transmission and reception behavior under different beams, effectively solving the problem that existing cell-level DTX and / or DRX configuration information is not well-suited for NTN multi-beam hopping scenarios. This invention enhances the DTX and / or DRX mechanism for NTN multi-beam hopping scenarios, effectively meeting actual communication needs, improving NTN system performance, and reducing system power consumption.
