Description

Technical Field

[0001] This application relates to the field of communications, and particularly to communication methods and apparatus in the field of communications. Background Technology

[0002] Discontinuous transmission (DTX) / discontinuous reception (DRX) technology is one of the important technologies for achieving energy saving in network devices and terminals. For example, a network device can configure a terminal with a cell DTX and / or cell DRX pattern. This network device can be a network device connected to the terminal. When the network device activates the cell DTX and / or cell DRX modes, the network device and the terminal can perform discontinuous transmission, thereby achieving energy saving for both the network device and the terminal.

[0003] However, the energy-saving performance of network equipment and terminals is still relatively poor. Summary of the Invention

[0004] This application provides a communication method and apparatus in order to improve the energy efficiency of network equipment and terminals.

[0005] Firstly, this application provides a communication method that can be executed by a terminal device. The terminal device can be the terminal itself, a component configured within the terminal (such as a processor, chip, chip system, etc.), or a logic module or software capable of implementing all or part of the terminal's functions; this application does not limit the scope of the method. The following uses a terminal as an example.

[0006] For example, the method includes: receiving first information broadcast by a first network device, the first information being used to indicate the configuration parameters of cell DTX and / or cell DRX of a second network device, the configuration parameters of cell DTX being used to determine the time period during which the second network device is in transmit mode, and the configuration parameters of cell DRX being used to determine the time period during which the second network device is in receive mode; and performing discontinuous transmission based on the first information.

[0007] Here, "time period" refers to a range / interval of time. The time period during which the second network device is in transmitting mode can refer to the time interval during which the second network device is in transmitting mode. Similarly, the time period during which the second network device is in receiving mode can refer to the time interval during which the second network device is in receiving mode.

[0008] For example, a time period can be represented in Universal Time, such as 7:30-7:40. A time period can also be represented in time slots, such as the second to the fourth time slot. A time period can also be represented in subframes, such as the second to the fourth subframe. A time period can also be represented in frames, such as the second to the fourth frame. This application does not limit the representation of time periods, and they will not be listed here.

[0009] The above method can be applied, for example, to scenarios where the terminal is in an idle or inactive state. The first network device can broadcast the configuration parameters of the cell DTX and / or cell DRX of the second network device. Correspondingly, even if the terminal is in an idle state, it can receive the configuration parameters of the cell DTX and / or cell DRX of the second network device from the first network device, thereby facilitating the terminal to perform discontinuous transmission with the second network device earlier. For example, a terminal in an idle state can perform discontinuous transmission before accessing the network device. In this way, the terminal can reduce unnecessary signal reception and transmission before accessing the network device, thereby improving the energy-saving effect of the terminal and the network device.

[0010] In conjunction with the first aspect, in some possible implementations of the first aspect, where the first information is used to indicate the configuration parameters of the cell DTX of the second network device, the above-mentioned discontinuous transmission based on the first information includes: monitoring the synchronization signal block (SSB) broadcast by the second network device based on the first information.

[0011] It should be noted that in this application, the aforementioned monitoring can be replaced by detection or reception, etc. When the first information indicates the cell DTX configuration parameters of the second network device, the second network device can perform discontinuous transmission. Correspondingly, the terminal can perform discontinuous reception. For example, based on the first information, the terminal can monitor the SSB broadcast by the second network device during the time period when the second network device is in transmission mode, or it can not monitor the SSB during the time period when the second network device is not transmitting information. It is easy to understand that the second network device will not transmit an SSB during the time period when it is not transmitting information, and conversely, the second network device may transmit an SSB only during the time period when it is in transmission mode. This monitoring method helps reduce the possibility that the terminal will monitor an SSB even when the second network device is not transmitting one. On the one hand, it can achieve the purpose of energy saving for the terminal; on the other hand, it can also improve the accuracy of the SSB measurement results. More specifically, if the second network device does not send an SSB, but the terminal measures the SSB, the signal quality obtained is poor, resulting in low accuracy of the SSB measurement results. By monitoring the SSB based on the aforementioned first information, it is beneficial to reduce the possibility that the second network device does not send an SSB, but the terminal monitors the SSB, thereby improving the accuracy of the SSB measurement results.

[0012] In conjunction with the first aspect, in some possible implementations of the first aspect, where the first information is used to indicate the cell DRX configuration parameters of the second network device, the above-mentioned discontinuous transmission based on the first information includes: sending second information to a third network device based on the first information, the second information being used to request random access, wherein the third network device is one of one or more of the second network devices.

[0013] In the four-step random access process, the aforementioned second information can be, for example, message (Msg) 1 (or random access preamble) or Msg 3 (or radio resource control (RRC) connection request). In the two-step random access process, the aforementioned second information can be, for example, Msg A (a combined random access preamble and RRC connection request). This application does not limit the type of random access.

[0014] In the above scheme, during the random access process, the terminal can also perform discontinuous transmission with the third network device based on the cell DRX configuration of the third network device. In this way, the terminal can reduce unnecessary signal reception and transmission before accessing the third network device, thereby making the energy-saving effect of the terminal and network device better.

[0015] In conjunction with the first aspect, in some possible implementations of the first aspect, the above method further includes: determining a third network device based on the aforementioned first information.

[0016] For example, before sending the second information to the third network device based on the first information, the terminal determines the third network device based on the first information.

[0017] In the above scheme, when determining the network device to be accessed, the terminal considers the cell DTX and / or cell DRX configuration of the network device. This facilitates faster network device access and improves access efficiency. For example, the terminal can choose to access a network device with a shorter duration that does not involve information transmission / reception.

[0018] In conjunction with the first aspect, in some possible implementations of the first aspect, where the first information is used to indicate the cell DTX configuration parameters of the second network device, the aforementioned discontinuous transmission based on the first information includes: monitoring third information from the third network device based on the first information, the third information being used to respond to a request during the random access process, wherein the length of the monitoring window corresponding to the third information is the sum of a first duration and at least one of the following: the duration during which the third network device does not transmit information in DTX mode, or the duration during which the third network device does not receive information in DRX mode. The first duration can be configured via system messages.

[0019] In the four-step random access process, the aforementioned third information can be, for example, Msg 2 (or random access response) or Msg 4 (or RRC connection setup). In the two-step random access process, the aforementioned third information can be, for example, Msg B (a combined random access response and RRC connection setup). This application does not limit the type of random access.

[0020] If the third network device is in DTX / DRX mode, and the terminal still monitors the third information based on the first duration, it may fail to detect the third information. For example, if the first duration is 2 seconds, but the third network device does not send information in DTX mode for 10 seconds after the terminal starts monitoring, meaning the third network device will not send third information within 10 seconds, the terminal will not detect the third information within the 2-second monitoring window. However, in the above solution, the length of the terminal's monitoring window for third information is the sum of the first duration and at least one of the following: the duration during which the third network device does not send information in DTX mode, or the duration during which the third network device does not receive information in DRX mode. This helps reduce the possibility of the terminal failing to detect the third information and improves the accuracy and completeness of monitoring.

[0021] In conjunction with the first aspect, in some possible implementations of the first aspect, the configuration parameters of the cell DTX indicate at least one of the following: DTX period, the duration of the second network device in transmit mode within a DTX period, or the start time of DTX; the configuration parameters of the cell DRX indicate at least one of the following: DRX period, the duration of the second network device in receive mode within a DRX period, or the start time of DRX.

[0022] In conjunction with the first aspect, in some possible implementations of the first aspect, the aforementioned first network device and / or second network device are located on a non-terrestrial network (NTN) device.

[0023] In other words, in the NTN communication system, the terminal can receive the first information broadcast by the first network device and perform discontinuous transmission based on the first information, thereby improving the energy-saving effect of the network device and the terminal.

[0024] Secondly, this application provides a communication method that can be executed by a network device. The network device can be the first network device itself, or a component configured in the first network device (such as a processor, chip, chip system, etc.), or a logic module or software capable of implementing all or part of the functions of the first network device. This application does not limit the scope of the method.

[0025] For example, the method includes: obtaining the configuration parameters of cell DTX and / or cell DRX of a second network device, wherein the configuration parameters of cell DTX are used to determine the time period during which the second network device is in transmit mode, and the configuration parameters of cell DRX are used to determine the time period during which the second network device is in receive mode; and broadcasting the configuration parameters of cell DTX and / or cell DRX of the second network device.

[0026] The explanation of the time period can be found in the first aspect, and will not be repeated here. The aforementioned first network device sends the first information via broadcast. On the one hand, terminals in an idle state can also receive the broadcast; on the other hand, more terminals can receive the broadcast, which helps reduce signaling overhead.

[0027] In the above scheme, the first network device can broadcast the cell DTX configuration parameters and / or cell DRX configuration parameters of the second network device. Correspondingly, even if the terminal is in an idle state, it can receive the cell DTX configuration parameters and / or cell DRX configuration parameters of the second network device from the first network device, thereby facilitating the terminal to perform discontinuous transmission with the second network device earlier. For example, the terminal in an idle state can perform discontinuous transmission before accessing the network device. In this way, the terminal can reduce unnecessary signal reception and transmission before accessing the network device, thereby making the energy-saving effect of the terminal and the network device better.

[0028] Optionally, the above-mentioned acquisition of the cell DTX configuration parameters and / or cell DRX configuration parameters of the second network device:

[0029] One possible implementation is to receive the cell DTX configuration parameters and / or cell DRX configuration parameters from the second network device. In other words, the second network device can report its own cell DTX configuration parameters and / or cell DRX configuration parameters to the first network device, thereby facilitating the first network device to broadcast these parameters so that the terminal can obtain them through the broadcast message from the first network device.

[0030] Another possible implementation is to predict the configuration parameters of the cell DTX and / or cell DRX of the second network device based on historical data. This historical data indicates the distribution of terminals served by the second network device. Predicting these parameters through the first network device eliminates the need for the second network device to report them, thus reducing signaling overhead.

[0031] In conjunction with the second aspect, in some possible implementations of the second aspect, the configuration parameters of the cell DTX indicate at least one of the following: DTX period, the duration of the second network device in transmit mode within a DTX period, or the start time of DTX; the configuration parameters of the cell DRX indicate at least one of the following: DRX period, the duration of the second network device in receive mode within a DRX period, or the start time of DRX.

[0032] In conjunction with the second aspect, in some possible implementations of the second aspect, the aforementioned first network device and / or second network device are located on the NTN device.

[0033] In other words, in the NTN communication system, the terminal can receive the first information broadcast by the first network device and perform discontinuous transmission based on the first information, thereby improving the energy-saving effect of the network device and the terminal.

[0034] Thirdly, this application provides a communication method that can be executed by a network device. The network device can be the third network device (an example of a network device accessed by a terminal) itself, or a component configured in the third network device (such as a processor, chip, chip system, etc.), or a logic module or software capable of implementing all or part of the functions of the third network device. This application does not limit the scope of the method.

[0035] For example, the method includes: broadcasting an SSB based on first information, the first information being used to indicate the configuration parameters of the cell DTX and / or the cell DRX of a third network device, wherein the configuration parameters of the cell DTX are used to determine the time period during which the third network device is in transmit mode, and the configuration parameters of the cell DRX are used to determine the time period during which the third network device is in receive mode.

[0036] For an explanation of the time period, please refer to the first part; it will not be repeated here.

[0037] Optionally, the third network device broadcasts an SSB based on the first information, including: the third network device broadcasts the SSB based on the first information and the SSB configuration. The SSB configuration may include, for example, the SSB period, time-domain resources, frequency-domain resources, etc., which will not be detailed here.

[0038] In conjunction with the third aspect, in some possible implementations of the third aspect, where the first information is used to indicate the cell DRX configuration parameters of the third network device, the above method further includes: receiving second information from the terminal based on the first information, the second information being used to request random access.

[0039] In conjunction with the third aspect, in some possible implementations of the third aspect, where the first information is used to indicate the configuration parameters of the cell DTX of the third network device, the method further includes: sending third information to the terminal based on the first information, the third information being used to respond to a request during the random access process.

[0040] In conjunction with the third aspect, in some possible implementations of the third aspect, the configuration parameters of the cell DTX indicate at least one of the following: DTX period, duration of the third network device in transmit mode within a DTX period, or the start time of DTX; the configuration parameters of the cell DRX indicate at least one of the following: DRX period, duration of the third network device in receive mode within a DRX period, or the start time of DRX.

[0041] In conjunction with the third aspect, in some possible implementations of the third aspect, the aforementioned third network device is located on the NTN device.

[0042] It should be understood that the third aspect of this application corresponds to the technical solution of the first aspect of this application, and the beneficial effects obtained by the third aspect and the corresponding feasible implementation are similar to those of the first aspect, and will not be repeated here.

[0043] Fourthly, this application provides a communication method that can be executed by a terminal device. The terminal device can be the terminal itself, a component configured within the terminal (such as a processor, chip, chip system, etc.), or a logic module or software capable of implementing all or part of the terminal's functions. This application does not limit the scope of the method. The following uses a terminal as an example.

[0044] For example, the method includes: receiving fourth information from a fourth network device, the fourth network device being a network device that establishes a connection with a terminal, the fourth information being used to indicate the configuration parameters of the cell DTX and / or cell DRX of the fourth network device, and the configuration parameters of the cell DTX and / or cell DRX of a fifth network device; determining a first time period based on the fourth information, the first time period being a time period during which one or more fifth network devices and each of the fourth network devices are in transmit mode, or the first time period being a time period during which one or more fifth network devices and each of the fourth network devices are in receive mode; and performing joint transmission with the one or more fifth network devices and the fourth network device during the first time period.

[0045] The configuration parameters of the cell DTX of the fourth network device are used to determine the time period during which the fourth network device is in transmit mode, the configuration parameters of the cell DRX of the fourth network device are used to determine the time period during which the fourth network device is in receive mode, the configuration parameters of the cell DTX of the fifth network device are used to determine the time period during which the fifth network device is in transmit mode, and the configuration parameters of the cell DRX of the fifth network device are used to determine the time period during which the fifth network device is in receive mode.

[0046] For an explanation of the time period, please refer to the first part; it will not be repeated here.

[0047] The above method can be applied, for example, to scenarios where the terminal is in a connected state. The fourth network device connected to the terminal can send its own cell DTX configuration parameters and / or cell DRX configuration parameters to the terminal, and can also send the cell DTX configuration parameters and / or cell DRX configuration parameters of one or more fifth network devices to the terminal. Correspondingly, when the terminal is in a connected state, it can receive not only the cell DTX configuration parameters and / or cell DRX configuration parameters of the fourth network device connected to it, but also the cell DTX configuration parameters and / or cell DRX configuration parameters of other network devices (one or more). This facilitates the terminal in determining the time period during which both the fourth and fifth network devices are in receive / transmit mode, and then the terminal performs joint transmission with the fourth and fifth network devices during the aforementioned time period. In scenarios where the fourth and fifth network devices collaboratively provide services to the terminal, this helps improve the energy-saving effect of the terminal and network devices (such as the fourth and fifth network devices).

[0048] In addition, the fourth network device that establishes a connection with the terminal sends the configuration parameters of the cell DTX and / or cell DRX of the fifth network device to the terminal. This makes it easier for the terminal to monitor the SSB broadcast by the fifth network device based on the above parameters, thus improving the energy-saving effect of the terminal and the fifth network device.

[0049] In conjunction with the fourth aspect, in some possible implementations of the fourth aspect, the above method further includes: receiving fifth information, the fifth information being used to indicate that the cell DTX of the fourth network device is activated and / or the cell DRX of the fourth network device is activated, and the cell DTX of the fifth network device is activated and / or the cell DRX of the fifth network device is activated; the above determination of the first time period based on the fourth information includes: determining the first time period based on the above fifth information and the fourth information.

[0050] In conjunction with the fourth aspect, in some possible implementations of the fourth aspect, the configuration parameters of the aforementioned cell DTX indicate at least one of the following: DTX period, duration of being in transmit mode within a DTX period, or the start time of DTX; the configuration parameters of the aforementioned cell DRX indicate at least one of the following: DRX period, duration of being in receive mode within a DRX period, or the start time of DRX.

[0051] In conjunction with the fourth aspect, in some possible implementations of the fourth aspect, the aforementioned fourth network device and / or fifth network device are located on the NTN device.

[0052] In other words, in the NTN communication system, the terminal can receive the aforementioned fourth information sent by the fourth network device, and then determine the first time period based on the aforementioned fourth information. During the first time period, it can perform joint transmission with the fourth network device and the fifth network device, thereby improving the energy-saving effect of the network device and the terminal.

[0053] Fifthly, this application provides a communication method that can be executed by a network device. The network device can be the fourth network device itself, a component configured in the fourth network device (such as a processor, chip, chip system, etc.), or a logic module or software capable of implementing all or part of the functions of the fourth network device. This application does not limit the scope of the method.

[0054] For example, the method includes: obtaining configuration parameters of cell DTX and / or cell DRX of a fifth network device, wherein the configuration parameters of cell DTX of the fifth network device are used to determine the time period during which the fifth network device is in transmit mode, and the configuration parameters of cell DRX of the fifth network device are used to determine the time period during which the fifth network device is in receive mode; and sending fourth information to a terminal, wherein the fourth information is used to indicate the configuration parameters of cell DTX and / or cell DRX of the fifth network device, and the configuration parameters of cell DTX and / or cell DRX of the fourth network device, wherein the configuration parameters of cell DTX of the fourth network device are used to determine the time period during which the fourth network device is in transmit mode, and the configuration parameters of cell DRX of the fourth network device are used to determine the time period during which the fourth network device is in receive mode.

[0055] In the above scheme, the fourth network device that establishes a connection with the terminal can not only send its own cell DTX configuration parameters and / or cell DRX configuration parameters to the terminal, but also send the cell DTX configuration parameters and / or cell DRX configuration parameters of the fifth network device (one or more) to the terminal. This makes it easier for the terminal to monitor the SSB broadcast by the fifth network device based on the cell DTX configuration parameters and / or cell DRX configuration parameters of the fifth network device (one or more). In this way, the energy saving effect of the terminal and the fifth network device is better.

[0056] Furthermore, the aforementioned parameters facilitate the terminal's determination of the time periods during which both the fourth and fifth network devices are in receive / transmit mode. This allows the terminal to perform joint transmission with the fourth and fifth network devices within those time periods. In scenarios where the fourth and fifth network devices collaborate to provide services to the terminal, this improves the energy efficiency of both the terminal and the network devices (fourth and fifth network devices).

[0057] The above describes how to obtain the configuration parameters of the cell DTX and / or cell DRX of the fifth network device:

[0058] One possible implementation is to receive the cell DTX configuration parameters and / or cell DRX configuration parameters from the fifth network device. In other words, the fifth network device can report its own cell DTX configuration parameters and / or cell DRX configuration parameters to the fourth network device, thereby facilitating the fourth network device to send these parameters to the terminal so that the terminal can obtain them.

[0059] Another possible implementation is to predict the configuration parameters of the cell DTX and / or cell DRX of the fifth network device based on historical data. This historical data indicates the distribution of terminals served by the fifth network device. Predicting these parameters via the fourth network device eliminates the need for the fifth network device to report them, thus reducing signaling overhead.

[0060] In conjunction with the fifth aspect, in some possible implementations of the fifth aspect, the configuration parameters of the aforementioned cell DTX indicate at least one of the following: DTX period, duration of being in transmit mode within a DTX period, or the start time of DTX; the configuration parameters of the aforementioned cell DRX indicate at least one of the following: DRX period, duration of being in receive mode within a DRX period, or the start time of DRX.

[0061] In conjunction with the fifth aspect, in some possible implementations of the fifth aspect, the aforementioned fourth network device and / or fifth network device are located on the NTN device.

[0062] Sixthly, this application provides a communication method that can be executed by a terminal device. The terminal device can be the terminal itself, a component configured within the terminal (such as a processor, chip, chip system, etc.), or a logic module or software capable of implementing all or part of the terminal's functions. This application does not limit the scope of the method. The following uses a terminal as an example.

[0063] For example, the method includes: receiving sixth information from a fourth network device, the fourth network device being a network device that has established a connection with a terminal, the sixth information indicating a first time period, the first time period being a time period in which one or more fifth network devices and each of the fourth network devices are in a transmitting mode, or the first time period being a time period in which one or more fifth network devices and each of the fourth network devices are in a receiving mode, the first time period being determined based on the configuration parameters of the cell DTX and / or cell DRX of one or more fifth network devices and the fourth network devices; and performing discontinuous transmission with the one or more fifth network devices and the fourth network device during the first time period.

[0064] The configuration parameters of the cell DTX of the fourth network device are used to determine the time period during which the fourth network device is in transmit mode, the configuration parameters of the cell DRX of the fourth network device are used to determine the time period during which the fourth network device is in receive mode, the configuration parameters of the cell DTX of the fifth network device are used to determine the time period during which the fifth network device is in transmit mode, and the configuration parameters of the cell DRX of the fifth network device are used to determine the time period during which the fifth network device is in receive mode.

[0065] The above method can be applied, for example, to scenarios where the terminal is in a connected state. The fourth network device, which establishes a connection with the terminal, can determine the time period during which all of the aforementioned network devices are in receive / transmit mode based on its own cell DTX and / or cell DRX configuration parameters, as well as the cell DTX and / or cell DRX configuration parameters of the fifth network device (or one or more). This information is then sent to the terminal, facilitating joint transmission with the fourth and fifth network devices during the specified time period. In scenarios where the fourth and fifth network devices collaboratively provide services to the terminal, this improves the energy efficiency of both the terminal and the network devices (fourth and fifth network devices).

[0066] In conjunction with the sixth aspect, in some possible implementations of the sixth aspect, the configuration parameters of the aforementioned cell DTX indicate at least one of the following: DTX period, duration of being in transmit mode within a DTX period, or the start time of DTX; the configuration parameters of the aforementioned cell DRX indicate at least one of the following: DRX period, duration of being in receive mode within a DRX period, or the start time of DRX.

[0067] In conjunction with the sixth aspect, in some possible implementations of the sixth aspect, the aforementioned fourth network device and / or fifth network device are located on the NTN device.

[0068] In a seventh aspect, this application provides a communication method that can be executed by a network device. The network device may be the fourth network device itself, or a component configured in the fourth network device (such as a processor, chip, chip system, etc.), or a logic module or software capable of implementing all or part of the functions of the fourth network device. This application does not limit the scope of the method.

[0069] For example, the method includes: obtaining configuration parameters of cell DTX and / or cell DRX of a fifth network device, wherein the configuration parameters of cell DTX of the fifth network device are used to determine the time period during which the fifth network device is in transmit mode, and the configuration parameters of cell DRX of the fifth network device are used to determine the time period during which the fifth network device is in receive mode; determining a first time period based on the configuration parameters of cell DTX and / or cell DRX of the fifth network device and the configuration parameters of cell DTX and / or cell DRX of a fourth network device, wherein the first time period is the time period during which one or more fifth network devices and each of the fourth network devices are in transmit mode, or the first time period is the time period during which one or more fifth network devices and each of the fourth network devices are in receive mode, wherein the configuration parameters of cell DTX of the fourth network device are used to determine the time period during which the fourth network device is in transmit mode, and the configuration parameters of cell DRX of the fourth network device are used to determine the time period during which the fourth network device is in receive mode; and sending sixth information to a terminal, wherein the sixth information is used to indicate the aforementioned first time period.

[0070] In the above scheme, the fourth network device that establishes a connection with the terminal can determine the time period during which all the aforementioned network devices are in receive / transmit mode based on its own cell DTX and / or cell DRX configuration parameters, as well as the cell DTX and / or cell DRX configuration parameters of the fifth network device (one or more). This information is then sent to the terminal, facilitating joint transmission with the fourth and fifth network devices during the specified time period. In scenarios where the fourth and fifth network devices collaboratively provide services to the terminal, this improves the energy efficiency of both the terminal and the network devices (fourth and fifth network devices).

[0073] Another possible implementation is to predict the configuration parameters of the cell DTX and / or cell DRX of the fifth network device based on historical data. This historical data indicates the distribution of terminals served by the fifth network device.

[0108] To facilitate understanding of the technical solution provided in this application, the following points are made first:

[0109] First, in this application, the terms “comprising” and “having” and any variations thereof are intended to cover non-exclusive inclusion, such as an apparatus, system, product or device that includes a series of modules, units or units, and is not necessarily limited to those listed, but may include other modules, units or units not listed or inherent to such apparatus, system, product or device.

[0110] Second, in this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, or B alone, where A and B can be singular or plural. The character " / " generally indicates an "or" relationship between the preceding and following related objects, but it does not exclude the possibility of indicating an "and" relationship; the specific meaning can be understood in context. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of singular or plural items. For example, at least one of a, b, or c can mean: a, b, c; a and b; a and c; b and c; or a and b and c. Here, a, b, and c can be single or multiple.

[0111] Third, in this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to a terminal" can be understood as the destination of the information being the terminal, which can include direct transmission via the air interface or indirect transmission via the air interface from other units or modules. "Receive information from a network device" can be understood as the source of the information being the network device, which can include direct reception from the network device via the air interface or indirect reception from the network device via the air interface from other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface.

[0112] In other words, sending and receiving can occur between devices, such as between network devices and terminals; or they can occur within a device, such as between components, modules, chips, software modules, or hardware modules within a device via a bus, wiring, or interface.

[0113] Fourth, in this application, “when…”, “if” and “if” all refer to the device making a corresponding processing under certain objective circumstances, and are not limited to a time, nor do they require the device to make a judgment when it is implemented, nor do they mean that there are other limitations.

[0114] Fifth, in this application, the words "example," "exemplarily," "for example," or "such as" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "example," "exemplarily," "for example," or "such as" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the words "example," "exemplarily," "for example," or "such as" is intended to present the relevant concepts in a specific manner.

[0115] Sixth, in this application, the term "terminal" may also be referred to as terminal equipment, user equipment (UE), mobile station, mobile terminal, etc. Terminals may include, but are not limited to: mobile phones, tablets, computers with wireless transceiver capabilities, virtual reality (VR) devices, augmented reality (AR) devices, mixed reality (MR) devices, extended reality (XR) devices, wireless terminals in industrial control, vehicle-mounted equipment, wireless terminals in autonomous driving, wireless terminals in remote medical care, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, wearable devices, video players, and full-range projectors, etc. This application does not limit the specific type of terminal.

[0116] In one possible scenario, network equipment (also known as radio access network (RAN) nodes) can be base stations (BS), evolved NodeBs (eNodeBs), transmission reception points (TRPs), home evolved NodeBs (or home Node Bs, HNBs), Wi-Fi access points (APs), mobile switching centers, next-generation NodeBs (gNBs) in 5G mobile communication systems, or base stations in future mobile communication systems. RAN nodes can also be devices that perform base station functions in device-to-device (D2D) communication systems, vehicle-to-everything (V2X) communication systems, machine-to-machine (M2M) communication systems, and internet-to-things (IoT) communication systems. RAN nodes can also be RAN nodes within an NTN (Network Node Network), meaning RAN nodes can be deployed on high-altitude platforms or satellites. RAN nodes can be macro base stations, micro base stations, indoor stations, relay nodes, donor nodes, etc., or radio controllers in cloud radio access network (CRAN) scenarios, or nodes in open radio access network (O-RAN or ORAN) scenarios. Optionally, RAN nodes can also be servers, wearable devices, vehicles, or in-vehicle equipment. For example, in V2X technology, RAN nodes can be roadside units (RSUs). Of course, RAN nodes can also be nodes in the core network.

[0117] In another possible scenario, multiple RAN nodes collaborate to assist the terminal in achieving wireless access, with each RAN node performing a portion of the base station's functions. For example, a RAN node can be a CU, a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU). CUs and DUs can be configured separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0118] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an open RAN (ORAN or O-RAN) system, CU can also be called open CU (O-CU), DU can also be called open DU (O-DU), CU-CP can also be called open CU-CP (O-CU-CP), CU-UP can also be called open CU-UP (O-CU-UP), and RU can also be called open RU (O-RU).

[0119] Any one of the CU (or CU-CP, CU-UP), DU, and RU units can be implemented through software modules, hardware modules, or a combination of software and hardware modules. That is, the wireless access network device in this application can be a virtualized device, for example, implemented through general-purpose hardware and instantiated virtualization functions, or dedicated hardware and instantiated virtualization functions. The general-purpose hardware can be a server, such as a cloud server.

[0120] Seventh, in the embodiments of this application, the terminal and / or network device may execute some or all of the steps in each embodiment. These steps or operations are merely examples, and the embodiments of this application may also execute other operations or variations thereof. Furthermore, the steps may be executed in different orders as presented in the embodiments, and it is not necessary to execute all the operations in the embodiments of this application. Moreover, the sequence number of each step does not imply the order of execution; the execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0121] To better understand the methods provided in the embodiments of this application, the terms involved in this application will be explained in detail below.

[0122] 1. NTN Communication: Compared to terrestrial communication, NTN communication offers advantages such as large coverage area and flexible networking. NTN communication utilizes devices such as drones, high-altitude platform stations (HAPS), and satellites to create networks, providing data transmission and voice communication services to terminals. High-altitude platform stations (HAPS) are typically located at altitudes of 8–50 kilometers above the ground. Based on satellite orbital altitude, satellite communication systems can be categorized into three types: geostationary earth orbit (GEO) satellite communication systems (also known as synchronous orbit satellite systems); medium earth orbit (MEO) satellite communication systems; and low earth orbit (LEO) satellite communication systems. GEO satellites orbit at an altitude of 35,786 km. The advantage of GEO satellite communication is its ability to remain relatively stationary relative to the ground and provide a large coverage area. MEO satellites orbit at altitudes between 2,000 km and 35,786 km. The advantage of MEO satellite communication is that it can achieve global coverage with a relatively small number of satellites. MEO satellites are primarily used for positioning and navigation. LEO satellites orbit at altitudes ranging from 300km to 2000km. Compared to MEO and GEO satellites, LEO satellites orbit at lower altitudes, offering advantages such as lower data propagation latency, less transmission loss, and relatively lower launch costs. Therefore, LEO satellite communication has gained widespread attention in recent years.

[0123] Depending on the payload type, NTN networks include two network architectures: regenerative architecture and transparent architecture. The following will combine... Figure 1 and Figure 2 The above network architecture will be explained.

[0124] Figure 1 This is a schematic diagram of a network architecture for NTN communication provided in an embodiment of this application.

[0125] like Figure 1As shown, during communication between the terminal and the base station, the satellite communicates with the gateway station (also known as a gateway or signaling station) via the Uu interface, the base station communicates with the 5th-generation core network (CN) via the next-generation (NG) interface, and the CN communicates with the data network via the N6 interface. The network communication segment between the terminal and the base station is called the remote radio unit (RAN unit), and the RAN node is used to ensure normal communication between the terminal and the CN. Figure 1 In the network architecture shown, the satellite can operate in transparent mode, for example. In this mode, the satellite can act as a relay for radio frequency filtering, frequency conversion, and amplification, regenerating the physical layer signal so that it is invisible to the protocol layer above the physical layer. The gateway station has the functions of a base station or part of a base station; in this case, the gateway station can be considered a base station. Alternatively, the base station can be deployed separately from the gateway station. In this case, the delay of the feeder link includes both the delay from the satellite to the gateway station and the delay from the gateway station to the base station. The base station can be deployed on the ground, for example.

[0126] Figure 2 This is a schematic diagram of another network architecture for NTN communication provided in the embodiments of this application.

[0127] like Figure 2 As shown, in this network architecture, for example, the satellite can operate in regenerative mode. In this mode, the satellite has data processing capabilities and functions as a base station or partially as one. The satellite can be considered a base station, or a base station can be deployed on the satellite, or the functions of a base station or partially integrated on the satellite. The satellite can communicate with the terminal via the Uu interface, and with the CN via the NG interface. The CN communicates with the data network via the N6 interface. During the communication between the satellite and the CN, the gateway station connects network segments using different protocols to ensure normal communication. In the satellite-gateway station network segment, the NG interface is the NG interface deployed in the satellite radio interface (SRI). The RAN node ensures normal communication between the terminal and the CN.

[0128] Optionally, in Figure 1 or Figure 2 In the network architecture shown, the satellites can be GEO satellites, MEO satellites, or LEO satellites. The satellites can also be replaced by other NTN devices such as HAPS devices and drones. This application does not limit the type of satellites.

[0129] It should be understood that, for the sake of brevity, the following will not be discussed further here. Figure 1 and Figure 2 To provide a more detailed explanation, regarding Figure 1 and Figure 2 A more detailed explanation of the architecture shown can be found in the 3rd generation partnership project (3GPP) technical report (TR) 23.501.

[0130] It should also be understood that the method provided in this application is applicable to terrestrial communication scenarios, satellite communication scenarios, scenarios where terrestrial networks and NTNs converge, and air-to-ground (ATG) communication scenarios; this application does not limit it in any way. The following will combine... Figures 3 to 7 The above scenarios will be described in detail.

[0131] Figure 3 This is a schematic diagram of the architecture of a terrestrial communication network.

[0132] like Figure 3 As shown, the communication system may include at least one network device, such as... Figure 3 The base station shown; the communication system may also include at least one terminal, such as Figure 3 The two terminals shown can communicate with each other via a wireless link.

[0133] Figure 3 An exemplary diagram shows one network device and two terminals, but this should not be construed as limiting the scope of this application. Optionally, the communication system may also include more or fewer network devices and terminals. Network devices may be routers, base stations, etc., and terminals may be mobile phones, tablets, smart bracelets, etc. The embodiments of this application do not limit the types of terminals and network devices.

[0134] Optionally, the above-mentioned communication system may also include other network entities such as network controllers and mobility management entities, and the embodiments of this application are not limited thereto.

[0135] It should also be understood that the method provided in the embodiments of this application can be applied to various communication systems, including NR communication systems. Figure 3 The communication system shown is merely an example. This application does not limit the specific architecture of the applicable system, nor does it limit the number and form of various devices contained in each communication system.

[0136] Figure 4 This is a schematic diagram of the NTN communication network architecture.

[0137] like Figure 4As shown in a), the communication system may include satellites, terminals, and network equipment (such as...). Figure 4 (The gateway stations and base stations shown). Satellites and terminals (such as...) Figure 4 The link between the aircraft, mobile phone (or other types of terminal shown) is called a service link, and the link between the satellite and the gateway station is called a feeder link. Figure 4 The communication system shown could be, for example, a network architecture where the satellite operates in transparent transmission mode, where the satellite is responsible for signal forwarding but has no data processing capabilities. The gateway station has the functions of a base station or some of the functions of a base station; in this case, the gateway station can be considered a base station. Alternatively, the base station can be deployed separately from the gateway station. In this case, the delay of the feeder link includes both the delay from the satellite to the gateway station and the delay from the gateway station to the base station. The base station could, for example, be deployed on the ground.

[0138] like Figure 4 As shown in b) of the diagram, in the regenerative architecture, the satellite possesses all or part of the functions of a base station; in other words, the satellite can perform data processing. Exemplarily, the complete base station is located on the satellite; or, the distributed unit (DU) of the base station is located on the satellite, while the centralized unit (CU) of the base station is located on the ground. These forms are merely examples and should not be construed as limiting the scope of the embodiments in this application. The link between the satellite / base station and the terminal is called a service link.

[0139] It should be understood that the satellite can also be replaced by other NTN devices such as HAPS equipment and drones, and this application does not limit the type of such devices.

[0140] Figure 5 and Figure 6 It is a network architecture that integrates terrestrial networks and NTN. Among them, in Figure 5 In the network architecture shown, NTN devices (such as satellites, HAPS devices, or drones) operate in transparent mode. Figure 6 In the network architecture shown, the NTN devices operate in regeneration mode. Figure 5 and Figure 6 In the network architecture shown, NTN devices are exemplified by GEO satellites, LEO satellites, HAPS devices, or drones, but this application does not limit their types.

[0141] Figure 5 This is a schematic diagram of a network architecture that integrates NTN and terrestrial networks.

[0142] like Figure 5 As shown, base stations in the terrestrial network ( Figure 5 Ground-based base stations (referred to as terrestrial base stations in NTN) and satellite base stations (referred to as satellite base stations to distinguish them from terrestrial network base stations) can communicate through a common core network, or through interfaces defined between base stations for more timely assistance and interconnection. NTN equipment (such as...) Figure 5 GEO satellites, LEO satellites, HAPS equipment, or drones in the network can communicate with the gateway station via the Uu interface, and base stations in the NTN can communicate with the core network via the NG interface. Satellite base stations can be deployed on the ground, for example.

[0143] Figure 6 This is a schematic diagram of another network architecture that integrates NTN and terrestrial networks.

[0144] like Figure 6 As shown, with Figure 5 The difference is that base stations in NTN are deployed on NTN equipment (which can be called airborne base stations). In other words, NTN equipment has data processing capabilities and functions as a base station or some of the functions of a base station. In this case, NTN equipment can be regarded as a base station. Base stations in terrestrial networks and base stations in NTN can be interconnected and communicate with each other through a common core network, or through interfaces defined between base stations to achieve more timely assistance and interconnection.

[0145] Figure 7 This is a schematic diagram of the network architecture for air-to-ground communication.

[0146] like Figure 7 As shown, this communication system includes network equipment and terminals. The network equipment can be, for example, a ground base station, and the terminals can be, for example, high-altitude aircraft, in-flight handheld terminals, etc. The terminals are located within the service range of the base station, for example... Figure 7 The circular area shown has a diameter of 100 to 300 kilometers.

[0147] It should be understood that Figure 7 The network architecture shown uses three base stations and three terminals as an example, but this should not be construed as limiting this application. For example, the above network architecture may include more or fewer network devices, and each network device may have a greater number of terminals within its coverage area.

[0148] It's easy to understand that NTN devices (taking satellites as an example) may be limited by manufacturing and launch costs, thus affecting onboard data processing capabilities and transmission power. Currently, satellite communication networks may not be able to provide terminals with communication rates comparable to terrestrial communication networks. To overcome this limitation and improve the overall signal processing capabilities and communication throughput of satellite networks, the number of satellites can be increased to compensate for the limitations of a single satellite's communication capabilities. For example, multiple satellites can work together to provide communication services to terminals (this can be called multi-satellite collaboration, or multi-star collaboration, etc.), meaning that the terminal can communicate with multiple satellites capable of communication.

[0149] Figure 8 This is a schematic diagram of multi-star coordination.

[0150] like Figure 8 As shown, satellites 1, 2, 3, and 4 can work together to provide services to the terminal. Compared to a single satellite providing services to the terminal, this can effectively improve communication reliability and data transmission rate. For example, satellites 1, 2, 3, and 4 can be medium Earth orbit (MEO) or low Earth orbit (LEO) satellites; this application does not limit the type of satellite.

[0151] Joint transmission is a multi-satellite collaborative technology that enables multiple transmission nodes (such as satellites / base stations) to work together to provide services to terminals. Joint transmission will be explained in detail below.

[0152] 2. Joint Transmission: This can be understood as multiple transmission nodes (such as satellites / base stations / TRPs, etc.) simultaneously sending signals to one or more terminals (a terminal can be considered as an example of a signal receiver). Correspondingly, the terminal can simultaneously receive signals from multiple transmission nodes. Joint transmission includes coherent joint transmission (CJT) and non-coherent joint transmission (NCJT). Coherent joint transmission can be understood as multiple transmission nodes simultaneously sending the same signal to the terminal, and the signals sent by these multiple transmission nodes are synchronized in time, frequency, and phase, so that the terminal can coherently combine and receive signals from multiple transmission nodes to enhance signal strength and quality. Non-coherent joint transmission can be understood as multiple transmission nodes simultaneously sending the same or different signals to the terminal. These signals do not need to be synchronized in phase, but they are synchronized in time and frequency.

[0153] 3. Cell DTX and Cell DRX: These are important technologies for network energy saving (NES). In existing technologies, when a terminal is in a connected state, the network device connected to the terminal can activate or deactivate the cell DTX / DRX mode (also simply referred to as activating or deactivating cell DTX / DRX). That is, cell DTX / DRX can be in an active or deactivated state. Cell DTX / DRX being active means that the network device and the terminal are communicating using cell DTX / DRX technology. Conversely, cell DTX / DRX being deactivated means that the network device and the terminal are not communicating using cell DTX / DRX technology.

[0154] 4. Activation and Deactivation: These are examples used to indicate whether a DTX / DRX mode / technology is in use. Activation can also be called enabling, and deactivation can also be called disabling. Correspondingly, activating cell DTX / DRX can also be called enabling cell DTX / DRX, and deactivating cell DTX / DRX can also be called disabling cell DTX / DRX. This application does not make specific limitations in this regard.

[0155] When the cell DTX is active (or DTX is activated), the network device can send information during the transmission mode period (also known as the DTX on time period). Correspondingly, the terminal can enable / enable the receiving function during this period to receive information from the network device. The network device can also not send information during the non-transmission period (also known as the DTX off time period). For example, in low-power mode, the terminal can disable the receiving function and not receive information from the network device during this period.

[0156] When the cell's DRX is active (or DRX is activated), the network device can receive information during the time period it is in receive mode (also known as the DRX on time period). Correspondingly, the terminal can enable / enable the transmit function during this time period and send information to the network device. The network device can not receive information during the time period it is not in receive mode (also known as the DRX off time period). For example, if it is in low power mode, the terminal can disable the transmit function and not send information to the network device during this time period.

[0157] It can be seen that the power consumption of network devices and terminals is lower during the periods when DRX is off and / or DTX is off. Therefore, when DTX / DRX is active, it can be considered that the goal of energy saving for network devices and terminals has been achieved.

[0158] For example, Figure 9 This is a diagram illustrating a cell DTX (or cell DRX) state that is active. When cell DTX (or cell DRX) is active, the time period during which the network device is in transmit mode (or receive mode) can be as follows: Figure 9 As shown in the raised portion, the time period during which no information is sent (or no information is received) can be as follows: Figure 9 The recessed portion is shown in the figure. The DTX period (or DRX period) can refer to the time interval between two consecutive moments when the system begins to enter the transmit mode (or receive mode), or the DTX period (or DRX period) can refer to the time interval between two consecutive moments when the system begins to enter the non-transmit mode (or non-receive mode).

[0159] As mentioned above, network devices can activate or deactivate cell DTX / DRX. Before that, network devices can configure the DTX / DRX mode (pattern) for the terminal, or in other words, indicate the cell DTX / DRX configuration parameters to the terminal.

[0160] For example, Figure 10 This is a schematic diagram illustrating the process of configuring DTX / DRX mode and activating / deactivating DTX / DRX on network devices.

[0161] In step 1001, the network device sends configuration information to the terminal, which is used to configure the cell's DTX / DRX mode. Correspondingly, the terminal receives the configuration information.

[0162] As one possible implementation, the above configuration information can be carried in an RRC message. In this application, each cell can be configured with one cell DTX / DRX mode, meaning that the terminals within this cell all have the same cell DTX / DRX mode.

[0163] In step 1002, the network device sends activation information to the terminal, which can be used to activate the cell DTX / DRX. Correspondingly, the terminal receives the activation information. Alternatively, in step 1003, the network device sends deactivation information to the terminal, which can be used to deactivate the cell DTX / DRX. Correspondingly, the terminal receives the deactivation information.

[0164] As one possible implementation, the activation / deactivation information mentioned above can be carried in a group common DCI (such as DCI 2_9). Activating / deactivating DTX / DRX through a group common DCI allows for the simultaneous activation / deactivation of DTX / DRX in multiple cells, thereby simplifying the complexity of control signaling and improving the efficiency of the activation / deactivation process.

[0165] For example, Figure 11 This is a schematic diagram of the DCI 2_9 format. (For example...) Figure 11 As shown, this DCI 2_9 can include multiple blocks. Figure 11 Only two blocks are shown (the ellipsis indicates more blocks). Each block corresponds to the DTX / DRX configuration of a cell. For example, block #i contains the DTX / DRX configuration associated with cell i. Within each block, the activation / deactivation of a specific cell's DTX / DRX can be indicated by binary bits of 0 and 1. For instance, if the indicator bit for the DTX configuration in block #i is 1, it means that cell i's DTX is activated; if the indicator bit for the DTX configuration in block #i is 0, it means that cell i's DTX is not activated.

[0166] After receiving activation / deactivation information, the terminal can adjust its receiving and transmitting behavior accordingly. For example, when DRX of a cell is activated, the terminal can enter discontinuous transmission mode; when DTX of a cell is activated, the terminal can enter discontinuous reception mode.

[0167] 5. Connected State: When a terminal is in connected state, it can mean that an RRC connection has been established between the terminal and the network, or it can be called RRC connected state. Figure 10 The method shown can be applied, for example, to scenarios where the terminal is in a connected state.

[0168] 6. Idle State (or Inactive State): The terminal being in the idle state can refer to being in the RRC idle state. In this state, no RRC connection is established between the terminal and the network. Although no RRC connection is established, the terminal can monitor broadcast messages from network devices, such as SSBs.

[0169] In some scenarios, Figure 10 Even with the method shown, the energy-saving effect of network devices and terminals is still relatively poor. For example, Figure 10In the method shown, when the terminal is in a connected state, the network device connected to the terminal can configure and activate the cell DTX / DRX configuration to facilitate energy saving for both the network device and the terminal. However, when the terminal is in an idle state, the terminal cannot use the aforementioned DTX mode to measure SSB, resulting in poor energy saving for both the terminal and the network device. For example, Figure 10 The method shown can be applied to scenarios where a single network device provides services to a terminal. However, when multiple network devices work together to provide services to a terminal, there is no corresponding discontinuous sending / receiving method, resulting in poor energy-saving performance for both the terminal and the network devices.

[0170] To improve the energy efficiency of terminals and network devices, this application provides a communication method in which a first network device can broadcast the configuration parameters of the cell DTX and / or cell DRX of a second network device. Correspondingly, even if the terminal is in an idle state, it can receive the configuration parameters of the cell DTX and / or cell DRX of the second network device from the first network device, thereby facilitating the terminal to perform discontinuous transmission with the second network device earlier.

[0171] The communication method provided in this application will now be described in detail with reference to the accompanying drawings.

[0172] The method provided in this application can be applied to Figures 1 to 7 The method shown in this application can also be applied to other networks, and this application does not limit this application.

[0173] The following describes in detail the methods provided in the embodiments of this application, using a terminal or network device (such as a first network device or a third network device) as the execution subject (a network device is an example of a network apparatus, and a terminal is an example of a terminal apparatus). The specific forms and quantities of the devices shown are merely examples and should not constitute any limitation on the implementation of the methods provided in this application. In the embodiments shown below, the terminal can also be replaced by components configured in the terminal (such as chips, chip systems, processors, etc.), or by logic modules or software capable of implementing all or part of the functions of the terminal. Similarly, the network device can also be replaced by components configured in the network device (such as chips, chip systems, processors, etc.), or by logic modules or software capable of implementing all or part of the functions of the network device. For example, the aforementioned network device could be... Figures 1 to 7 The network architecture shown includes base stations (terrestrial base stations, satellite base stations, airborne base stations, etc.). It should be noted that in a transparent transmission architecture, information sent by network devices can be forwarded via NTN devices (such as satellites).

[0174] Figure 12 This is a schematic flowchart of the communication method 1200 provided in the embodiments of this application.

[0175] Figure 12The method 1200 shown includes steps 1201 to 1203. The individual steps in method 1200 are described in detail below.

[0176] In step 1201, the first network device obtains the configuration parameters of the cell DTX and / or cell DRX of the second network device.

[0177] The configuration parameters of cell DTX are used to determine the time period during which the second network device is in transmit mode, and the configuration parameters of cell DRX are used to determine the time period during which the second network device is in receive mode. The second network device can be one or more.

[0178] The aforementioned time period refers to a range / interval of time. The time period during which the second network device is in transmitting mode can refer to the time interval during which the second network device is in transmitting mode. Similarly, the time period during which the second network device is in receiving mode can refer to the time interval during which the second network device is in receiving mode.

[0179] For example, a time period can be represented in Universal Time, such as 7:30-7:40. A time period can also be represented in time slots, such as the second to the fourth time slot. A time period can also be represented in subframes, such as the second to the fourth subframe. A time period can also be represented in frames, such as the second to the fourth frame. This application does not limit the representation of time periods, and they will not be listed here.

[0180] The first network device acquires the cell DTX configuration parameters and / or cell DRX configuration parameters of the second network device. The cell DTX configuration parameters of the second network device are used to determine / indicate in which time interval the second network device can transmit signals, and can also be used to determine in which time interval the second network device does not transmit signals. The cell DRX configuration parameters of the second network device are used to determine / indicate in which time interval the second network device can receive signals, and can also be used to determine in which time interval the second network device does not receive signals.

[0181] Optionally, the configuration parameters of the cell DTX indicate at least one of the following: DTX period, duration of the second network device in transmit mode within a DTX period, or the start time of DTX; the configuration parameters of the cell DRX indicate at least one of the following: DRX period, duration of the second network device in receive mode within a DRX period, or the start time of DRX.

[0182] For example, the configuration parameters of the cell DRX indicate the DRX period, the length of the DRX period within a DRX period, and the start time of DRX. Based on the above configuration parameters, the terminal can determine in which time intervals the second network device is in receiving mode (or can receive signals) and in which time intervals it does not receive information.

[0183] Similarly, the configuration parameters of the cell DTX mentioned above indicate the DTX period, the length of the time period during which DTX is enabled within a DTX period, and the start time of DTX. Based on the above configuration parameters, the terminal can determine in which time interval the second network device is in transmission mode (or can transmit signals) and in which time interval it does not transmit information.

[0184] The aforementioned start time of DRX / DTX can refer, for example, to the start time slot of DRX / DTX. For instance, the network device can indicate the subframe offset, DRX / DTX period, and time slot offset to enable the terminal to determine the start time slot of DRX / DTX. The terminal can, for example, determine the start subframe of DRX / DTX based on the DRX / DTX period and subframe offset, and then determine the start time slot of DRX / DTX based on the time slot offset. The aforementioned start time of DRX / DTX can also be indicated by a specific time, which is not limited in this application.

[0185] Optionally, the configuration parameters for cell DTX mentioned above indicate one or both of the following: DTX period, the duration of the second network device in transmission mode within a DTX period, or the start time of DTX. Parameters not indicated (such as DTX period) can be predefined. Cell DRX is similar and will not be described in detail here.

[0186] In step 1202, the first network device broadcasts first information, which indicates the configuration parameters of the cell DTX and / or cell DRX of the second network device. Correspondingly, the terminal receives the aforementioned first information.

[0187] The aforementioned terminal can be a terminal in an idle state (or an inactive state).

[0188] For example, the first network device can broadcast the aforementioned first information via system messages (or system information). Correspondingly, the terminal obtains the aforementioned first information from the system messages. The system messages include various information used by the network device to notify the terminal about the system, such as network information of the cell where the terminal is located, information about the registration area, information about the common channel, and information about other cells, etc., all system-related information. The system messages include a system information block (SIB) 1 and other system information blocks (OSI).

[0189] In step 1203, the terminal performs discontinuous transmission with the second network device based on the aforementioned first information.

[0190] Specifically, when the first information indicates the cell DTX configuration parameters of the second network device, the second network device can perform discontinuous transmission based on the first information, and correspondingly, the terminal can perform discontinuous reception based on the first information.

[0191] In the above scheme, the first network device can broadcast the cell DTX configuration parameters and / or cell DRX configuration parameters of the second network device. Correspondingly, even if the terminal is in an idle state, it can receive the cell DTX configuration parameters and / or cell DRX configuration parameters of the second network device from the first network device, thereby facilitating the terminal to perform discontinuous transmission with the second network device earlier. For example, the terminal in an idle state can perform discontinuous transmission before accessing the network device. In this way, the terminal can reduce unnecessary signal reception and transmission before accessing the network device, thereby making the energy-saving effect of the terminal and the network device better.

[0192] As an example, in NTN communication systems (such as...) Figure 1 , Figure 2 ,or Figure 4 In the communication system shown, the first network device and / or the second network device may be located on an NTN device (such as a satellite). For example, if the NTN device is a satellite and the communication architecture is a regenerative architecture, the first network device and the second network device are located on the satellite. The satellite on which the first network device is located is denoted as the first satellite, and the satellite on which the second network device is located is denoted as the second satellite. The first satellite can broadcast the configuration parameters of the cell DTX and / or cell DRX of the second satellite (one or more second satellites) to facilitate discontinuous transmission between the terminal and the second satellite.

[0193] If the second satellite broadcasts its own cell DTX configuration parameters and / or cell DRX configuration parameters, for example, in the SIB, the terminal will not be able to perform discontinuous reception when receiving the SSB of the second satellite (because the SSB is received before the SIB), resulting in poor energy saving for both the terminal and the satellite. Therefore, the first satellite broadcasts the cell DTX configuration parameters and / or cell DRX configuration parameters of the second satellite so that the terminal can receive the SSB of the second satellite based on these parameters, thereby improving the energy saving effect for both the satellite and the terminal.

[0194] Optionally, the first satellite can be, for example, a high-orbit satellite, and the second satellite can be, for example, a low-orbit or medium-orbit satellite. On the one hand, high-orbit satellites have a larger coverage area, allowing more terminals to receive their broadcast messages. Therefore, broadcasting the cell DTX and / or DRX configuration parameters of low-orbit / medium-orbit satellites from a high-orbit satellite can be received by more terminals, enabling discontinuous transmission, thus saving energy for the terminals. Furthermore, compared to broadcasting from low-orbit / medium-orbit satellites, this method reduces signaling overhead. On the other hand, since terminals need to perform discontinuous transmission with the second satellite, and low-orbit / medium-orbit satellites have lower latency and faster data rates, it is more suitable to use a low-orbit / high-orbit satellite as the second satellite.

[0195] As another example, in terrestrial networks (such as...) Figure 3 In the communication system shown, the first network device can broadcast the configuration parameters of the cell DTX and / or cell DRX of the second network device. The first network device and the second network device can be, for example, a ground base station or a TRP.

[0196] As an optional embodiment, the first network device obtains the cell DTX configuration parameters and / or cell DRX configuration parameters of the second network device, which can be achieved through any of the following methods:

[0197] Implementation Method 1: The first network device receives the cell DTX configuration parameters and / or cell DRX configuration parameters from the second network device. In other words, the second network device can send its own cell DTX configuration parameters and / or cell DRX configuration parameters to the first network device, thereby facilitating the first network device to broadcast these parameters so that the terminal can obtain them through the broadcast message from the first network device.

[0198] Implementation Method Two: The first network device predicts the configuration parameters of the cell DTX and / or cell DRX of the second network device based on historical data from the second network device. This historical data indicates the distribution of terminals served by the second network device. Predicting these parameters by the first network device eliminates the need for the second network device to report them, thus reducing signaling overhead.

[0199] For example, the first network device can predict the cell DTX configuration parameters and / or cell DRX configuration parameters of the second network device based on the distribution of user terminals. For instance, the more terminals within the coverage area of ​​the second network device, the longer the second network device remains in transmit mode under DTX mode, and / or the longer the second network device remains in receive mode under DRX mode. Alternatively, the more terminals within the coverage area of ​​the second network device, the shorter the time the second network device does not transmit information under DTX mode, and / or the shorter the time the second network device does not receive information under DRX mode.

[0200] For example, such as Figure 13 As shown, assuming that the number of terminals within the coverage area of ​​network device 2 is greater than the number of terminals within the coverage area of ​​network device 1, and that network device 1 and network device 2 have the same DRX / DTX period, then the duration of the DRX / DTX enabled period of network device 2 is longer than the duration of the DRX / DTX enabled period of network device 1.

[0201] Figure 12 In the method 1200 shown, the terminal can perform discontinuous transmission with the second network device based on the first information. As an optional embodiment, when the first information is used to indicate the configuration parameters of the cell DTX of the second network device, the discontinuous transmission based on the first information includes: monitoring the SSB broadcast by the second network device based on the first information.

[0202] Here, monitoring can be replaced by detection or reception, etc. When the first information indicates the cell DTX configuration parameters of the second network device, the second network device can perform discontinuous transmission, and correspondingly, the terminal can perform discontinuous reception.

[0203] For example, the terminal can monitor the SSB broadcast by the second network device during the time period when the second network device is in transmission mode, based on the first information. Alternatively, the terminal can refrain from monitoring the SSB during the time period when the second network device is not transmitting information.

[0204] For the second network device, it can broadcast an SSB based on the aforementioned first information. For example, the second network device can broadcast an SSB during a time period when it is in transmission mode, based on the first information. Alternatively, the second network device can choose not to broadcast an SSB during periods when it is not transmitting information.

[0205] Optionally, the second network device broadcasts an SSB based on the first information, including: the second network device broadcasts the SSB based on the first information and the SSB configuration. The SSB configuration includes, for example, the SSB period, time-domain resources, frequency-domain resources, etc., which will not be detailed here. For example, the second network device can broadcast the SSB if the time-domain resources configured in the SSB configuration coincide with the time period in the transmission mode.

[0206] It's easy to understand that the second network device won't send SSBs during periods when it's not transmitting information. Conversely, the second network device might send SSBs only during periods when it's in transmission mode. This monitoring method helps reduce the possibility that the terminal will monitor SSBs even when the second network device isn't sending them. This achieves energy saving for the terminal and also improves the accuracy of SSB measurement results. If the second network device isn't sending SSBs, but the terminal is measuring them, the signal quality will be poor, leading to lower accuracy in the SSB measurement results. By monitoring SSBs based on the aforementioned first information, the possibility of the terminal monitoring SSBs even when the second network device isn't sending them is reduced, thus improving the accuracy of SSB measurement results.

[0207] Figure 12 In method 1200, the terminal can perform discontinuous transmission with the second network device based on the first information. As an optional embodiment, when the first information is used to indicate the cell DRX configuration parameters of the second network device, the discontinuous transmission based on the first information includes: sending second information to a third network device based on the first information, the second information being used to request random access, wherein the third network device is one or more of the second network devices. Correspondingly, the third network device can receive the second information based on the first information.

[0208] In the four-step random access process, the second piece of information mentioned above can be, for example, Msg 1 (or random access preamble) or Msg 3 (or RRC connection request). In the two-step random access process, the second piece of information mentioned above can be, for example, Msg A (a combined random access preamble and RRC connection request). This application does not limit the type of random access.

[0209] During the random access process, the terminal can also perform discontinuous transmission with the third network device based on the cell DRX configuration of the third network device. In this way, the terminal can reduce unnecessary signal reception and transmission before accessing the third network device, thereby improving the energy-saving effect of the terminal and network device.

[0210] For example, a terminal can send a preamble based on the cell DRX configuration and random access timing of the third network device, and correspondingly, the third network device can receive the preamble based on the cell DRX configuration and random access timing. As another example, a terminal can send an RRC connection request based on the cell DRX configuration of the third network device, and correspondingly, the third network device can receive the RRC connection request based on the cell DRX configuration.

[0211] Figure 12 In method 1200, the terminal can perform discontinuous transmission with the second network device based on the aforementioned first information. As an optional embodiment, when the first information is used to indicate the cell DTX configuration parameters of the second network device, the discontinuous transmission based on the first information includes: monitoring third information from a third network device based on the first information. This third information is used to respond to requests during the random access procedure. The length of the monitoring window corresponding to this third information is the sum of a first duration and at least one of the following: the duration during which the third network device does not send information in DTX mode, or the duration during which the third network device does not receive information in DRX mode. The first duration can be configured via system messages. Correspondingly, the third network device sends the third information based on the first information.

[0212] In the four-step random access process, the aforementioned third information can be, for example, Msg 2 (or random access response) or Msg 4 (or RRC connection setup). In the two-step random access process, the aforementioned third information can be, for example, Msg B (a combined random access response and RRC connection setup). This application does not limit the type of random access.

[0213] If the third network device is in DTX / DRX mode, and the terminal still monitors the third information based on the first duration, it may fail to detect the third information. For example, if the first duration is 2 seconds, but the third network device does not send information in DTX mode for 10 seconds after the terminal starts monitoring, meaning the third network device will not send third information within 10 seconds, the terminal will not detect the third information within the 2-second monitoring window. However, in the above solution, the length of the terminal's monitoring window for third information is the sum of the first duration and at least one of the following: the duration during which the third network device does not send information in DTX mode, or the duration during which the third network device does not receive information in DRX mode. This helps reduce the possibility of the terminal failing to detect the third information and improves the accuracy and completeness of monitoring.

[0214] For example, a third network device can send Msg 2 according to the cell DTX configuration. Correspondingly, the terminal can monitor Msg 2 according to the cell DTX configuration of the third network device. The length of the monitoring window for Msg 2 is: first duration + duration during which the third network device does not receive information in DRX mode + duration during which the third network device does not send information in DTX mode; or, the length of the monitoring window for Msg 2 is: first duration + duration during which the third network device does not receive information in DRX mode; the length of the monitoring window for Msg 2 is: first duration + duration during which the third network device does not send information in DTX mode. The duration during which the third network device does not send information in DTX mode refers to the duration during which it does not send information in DTX mode after the terminal starts the monitoring window (or starts the timer); the duration during which the third network device does not receive information in DRX mode refers to the duration during which it does not receive information in DRX mode after the terminal starts the monitoring window (or starts the timer).

[0215] For example, a third network device can send Msg 4 according to the cell DTX configuration. Correspondingly, the terminal can monitor Msg 4 according to the cell DTX configuration of the third network device. The length of the monitoring window for Msg 4 is equal to the first duration + the duration during which the third network device does not receive information in DRX mode + the duration during which the third network device does not send information in DTX mode; or, the length of the monitoring window for Msg 2 is equal to the first duration + the duration during which the third network device does not receive information in DRX mode; the length of the monitoring window for Msg 2 is equal to the first duration + the duration during which the third network device does not send information in DTX mode.

[0216] Optionally, before sending the second information to the third network device based on the first information, the terminal may also determine the third network device based on the first information.

[0217] By considering the cell DTX and / or cell DRX configurations of the network devices when determining which devices need to be accessed, terminals can access network devices more quickly and efficiently. For example, terminals can choose to access network devices with shorter durations that do not involve information transmission / reception.

[0218] For example, a terminal can determine a third network device based on the S criterion and the configuration parameters of cell DTX and / or cell DRX. For instance, the terminal can monitor the SSB of one or more second network devices and, based on the SSB measurement results, determine which of the one or more second network devices meets the S criterion in terms of signal quality. Meeting the S criterion can be understood as both the cell-selected received signal strength value (Srxlev) and the cell-selected received signal quality value (Squal) being greater than 0. Srxlev is typically negative, representing the strength level of the received signal; a higher value indicates better signal quality. Squal is typically negative, representing the quality of the received signal; a higher value indicates better signal quality. When the terminal determines that the SSB of multiple network devices meets the S criterion, it can determine the third network device based on the configuration parameters of the cell DTX and / or cell DRX of each of the multiple second network devices. For example, the terminal can choose to camp on and access a network device with a shorter duration that does not transmit / receive information.

[0219] Figure 12 The illustrated method demonstrates a discontinuous transmission process when the terminal is in an idle state. This application also provides a communication method where, in a connected state, the fourth network device connected to the terminal can send its own cell DTX configuration parameters and / or cell DRX configuration parameters to the terminal, as well as the cell DTX configuration parameters and / or cell DRX configuration parameters of one or more fifth network devices. Correspondingly, when the terminal is in a connected state, it can receive not only the cell DTX configuration parameters and / or cell DRX configuration parameters of the fourth network device connected to it, but also the cell DTX configuration parameters and / or cell DRX configuration parameters of other network devices (one or more). This facilitates the terminal in determining the time period during which both the fourth and fifth network devices are in receive / transmit mode, and then the terminal performs joint transmission with the fourth and fifth network devices during the aforementioned time period. In scenarios where the fourth and fifth network devices collaboratively provide services to the terminal, this method helps improve the energy-saving effect of the terminal and network devices (fourth and fifth network devices).

[0220] In addition, the fourth network device that establishes a connection with the terminal sends the cell DTX configuration parameters and / or cell DRX configuration parameters of the fifth network device to the terminal. This makes it easier for the terminal to monitor the SSB broadcast by the fifth network device based on the above parameters, thus improving the energy-saving effect of the terminal and the fifth network device.

[0221] The following will combine Figure 14 The above communication methods will be explained in detail.

[0222] Figure 14This is a schematic flowchart of another communication method 1400 provided in the embodiments of this application.

[0223] Figure 14 The method 1400 shown includes steps 1401 to 1404. The individual steps in method 1400 are described in detail below.

[0224] In step 1401, the fourth network device obtains the configuration parameters of the cell DTX and / or cell DRX of the fifth network device.

[0225] The fourth network device mentioned above can be a network device that establishes a connection with the terminal (such as an RRC connection). The fifth network device can be a network device that collaboratively provides services to the terminal.

[0226] The configuration parameters of the cell DTX of the aforementioned fifth network device are used to determine the time period during which the fifth network device is in transmit mode, and the configuration parameters of the cell DRX of the aforementioned fifth network device are used to determine the time period during which the fifth network device is in receive mode. The aforementioned fifth network device can be one or more.

[0227] For an explanation of the above time period, please refer to [link / reference]. Figure 12 This will not be elaborated upon here.

[0228] The fourth network device obtains the cell DTX configuration parameters and / or cell DRX configuration parameters of the fifth network device. The cell DTX configuration parameters of the fifth network device are used to determine / indicate in which time interval the fifth network device can transmit signals, and the cell DRX configuration parameters of the fifth network device are used to determine / indicate in which time interval the fifth network device can receive signals.

[0229] Optionally, the configuration parameters of cell DTX indicate at least one of the following: DTX period, duration of being in transmit mode within a DTX period, or start time of DTX; the configuration parameters of cell DRX indicate at least one of the following: DRX period, duration of being in receive mode within a DRX period, or start time of DRX.

[0230] For an explanation of the above parameters, please refer to [link / reference]. Figure 12 This will not be elaborated upon here.

[0231] In step 1402, the fourth network device sends fourth information to the terminal. This fourth information indicates the configuration parameters of the cell DTX and / or cell DRX of the fourth network device, as well as the configuration parameters of the cell DTX and / or cell DRX of the fifth network device. Correspondingly, the terminal receives the aforementioned fourth information. The explanation of the configuration parameters of the cell DTX and / or cell DRX of the fourth network device is similar to that of the fifth network device, and will not be repeated here.

[0232] The aforementioned terminal may be a terminal in a connected state. The fourth network device connected to the terminal may indicate to the terminal the configuration parameters of the fourth network device's cell DTX and / or cell DRX, as well as the configuration parameters of the fifth network device's cell DTX and / or cell DRX.

[0233] For example, the fourth network device can indicate to the terminal the configuration parameters of the cell DTX and / or cell DRX of the fourth network device, as well as the configuration parameters of the cell DTX and / or cell DRX of the fifth network device, through an RRC message. In other words, the aforementioned fourth information can be carried in the RRC message.

[0234] As an example, in NTN communication systems (such as...) Figure 1 , Figure 2 ,or Figure 4 In the communication system shown, the fourth network device and / or the fifth network device may be located on an NTN device (such as a satellite). For example, if the NTN device is a satellite and the communication architecture is a regenerative architecture, the fourth network device and the fifth network device are located on a satellite. The satellite on which the fourth network device is located is denoted as the fourth satellite (which may be called the serving satellite), and the satellite on which the fifth network device is located is denoted as the fifth satellite (which may be called the non-serving satellite). The fourth satellite may send the configuration parameters of the cell DTX and / or the cell DRX of the fourth satellite, as well as the configuration parameters of the cell DTX and / or the cell DRX of the fifth satellite (one or more fifth satellites), to the terminal so that the terminal can determine the first time period based on this.

[0235] As another example, in terrestrial networks (such as...) Figure 3 In the communication system shown, the fourth network device can send the configuration parameters of the cell DTX and / or cell DRX of the fourth network device, as well as the configuration parameters of the cell DTX and / or cell DRX of the fifth network device (one or more fifth network devices), to the terminal. The fourth network device and the fifth network device can be, for example, a ground base station or a TRP.

[0236] In step 1403, the terminal determines the first time period based on the aforementioned fourth information.

[0237] The first time period mentioned above is either the time period during which one or more fifth network devices and each of the fourth network devices are in transmitting mode, or the first time period is the time period during which one or more fifth network devices and each of the fourth network devices are in receiving mode.

[0238] After receiving the aforementioned fourth information, the terminal can determine, based on the cell DTX configuration parameters and / or cell DRX configuration parameters of the fourth network device, which time period the fourth network device is in transmit mode / receive mode, and based on the cell DTX configuration parameters and / or cell DRX configuration parameters of the fifth network device, determine which time period the fifth network device is in transmit mode / receive mode, thereby determining the time periods during which one or more fifth network devices and each of the fourth network devices are in transmit mode, or the time periods during which one or more fifth network devices and each of the fourth network devices are in receive mode, so as to facilitate joint transmission with the aforementioned one or more fifth network devices and fourth network devices.

[0239] For example, the cell DTX / DRX mode of the fourth network device (network device 1 in the figure) and the fifth network device ( Figure 15 Taking network devices 2 and 3 as examples, the DTX / DRX mode of the cell is as follows: Figure 15 As shown, the terminal determines the time period during which each of the two fifth network devices and the fourth network device is in transmit / receive mode, as follows: Figure 15 The dashed box portion is shown in the image.

[0240] In step 1404, the terminal performs joint transmission with one or more fifth network devices and the fourth network device during the first time period.

[0241] Specifically, when the first time period is a time during which each of the one or more fifth network devices and the fourth network device is in transmit mode, the one or more fifth network devices and the fourth network device can transmit signals during the first time period, and correspondingly, the terminal can receive signals from the one or more fifth network devices and the fourth network device during the first time period. When the first time period is a time during which each of the one or more fifth network devices and the fourth network device is in receive mode, the terminal can transmit signals to the one or more fifth network devices and the fourth network device during the first time period, and correspondingly, the one or more fifth network devices and the fourth network device can receive signals during the first time period.

[0242] Optionally, the above method further includes: receiving fifth information, the fifth information being used to indicate that the cell DTX of the fourth network device is activated and / or the cell DRX of the fourth network device is activated, and the cell DTX of the fifth network device is activated and / or the cell DRX of the fifth network device is activated; the above determination of the first time period based on the fourth information includes: determining the first time period based on the above fifth information and the fourth information.

[0243] When the terminal is in a connected state, after the fourth network device sends the fourth information to the terminal, it can activate the cell DTX / DRX of the fourth network device and / or the fifth network device through the fifth information. After receiving the fifth information, the terminal identifies multiple network devices whose cell DTX / DRX has been activated, and then determines the time period during which these multiple network devices are all in transmit / receive mode based on the cell DTX / DRX configuration parameters of each of these multiple network devices, and performs joint transmission with these multiple network devices during this time period.

[0244] In one example, network device 1 is a network device that establishes a connection with the terminal. Network device 1 instructs the terminal on the cell DTX / DRX configuration parameters of each of the network devices 1, 2, 3, and 4. Network devices 2, 3, and 4 can be network devices adjacent to network device 1 (e.g., geographically adjacent). Furthermore, network device 1 instructs the terminal to activate the cell DTX / DRX of network devices 1, 2, and 3. The terminal can then determine, based on the cell DTX / DRX configuration parameters of each of the network devices 1, 2, and 3, the time periods during which all three network devices are in transmit / receive mode (e.g., time period 1 and time period 2), and perform joint transmission with network devices 1, 2, and 3 within these time periods (e.g., CJT or NCJT). This application does not limit the specific transmission method used.

[0245] It is understandable that, assuming a fourth network device activates the cell DTX / DRX of M network devices, but only the time periods of the transmission / reception modes corresponding to N network devices overlap or partially overlap, the terminal can perform joint transmission with this network device. For example, in the above example, network device 1 instructs the terminal to activate the cell DTX / DRX of network devices 1, 2, and 3, but only the time periods of the transmission / reception modes corresponding to network devices 1 and 2 overlap or partially overlap. In this case, the terminal performs joint transmission with network devices 1 and 2, such as CJT or NCJT. This application does not limit this.

[0246] This application also provides a communication method in which, when the terminal is in a connected state, a fourth network device connected to the terminal can determine the time period during which both the fourth and fifth network devices are in receive / transmit mode based on its own cell DTX and / or cell DRX configuration parameters, as well as the cell DTX and / or cell DRX configuration parameters of one or more fifth network devices. This allows the fourth network device to schedule joint transmission with the terminal. In scenarios where the fourth and fifth network devices collaboratively provide services to the terminal, this method helps improve the energy efficiency of both the terminal and the network devices (fourth and fifth network devices).
