Description

Communication method and communication device

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on November 17, 2023, with application number 202311547854.7 and invention name “A Communication Method and Communication Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communications, and in particular to a communication method and a communication device. Background Art

[0003] As wireless communications have larger bandwidths and more antennas, energy saving for base stations and terminals is a hot topic in wireless communications.

[0004] Among them, one technical feature of base station energy saving is cell discontinuous transmission (DTX) / discontinuous reception (DRX). The basic idea is that the base station only sends and receives certain signals within periodic time windows, that is, it does not receive or send these signals outside the above time windows. One technical feature of terminal energy saving is the reception mechanism based on the wake-up signal. The basic idea is that the terminal periodically detects the wake-up signal. Once the wake-up signal triggers the terminal to start receiving, the terminal will receive certain signals within the next period of time corresponding to the wake-up signal. Otherwise, the terminal will not receive these signals. Terminal devices configured with a low power wake-up signal (LP-WUS) adopt a combination of primary and secondary receiving links. The primary link is in an ultra-deep sleep state before being awakened by LP-WUS.

[0005] However, there is currently no technical solution for combining the above-mentioned LP-WUS with DTX / DRX.

[0006] Summary of the Invention

[0007] The embodiments of the present application provide a communication method and related devices. In a scenario where LP-WUS is combined with DTX / DRX, a terminal device can transmit a third signal during a first activation period activated by a low-power wake-up signal, even outside the second / third activation period of cell DTX or cell DRX. Alternatively, this method can be understood as removing the restriction of cell DTX / DRX on signal transmission during the first activation period corresponding to the wake-up signal, thereby balancing terminal power consumption, service experience, and base station power consumption.

[0008] In a first aspect, the present application provides a communication transmission method, which is executed by a terminal device (or terminal), or the method is executed by some components in the terminal device (such as a processor, a chip or a chip system, etc.), or the method can also be implemented by a logic module or software that can realize all or part of the terminal device functions. In the first aspect and its possible implementation, the method is described as being executed by a terminal device. In this method, the terminal device obtains first configuration information and second configuration information, the first configuration information is used to configure the time domain resources of the first activation time period for the terminal device to receive a low power wake-up signal LP-WUS, and the second configuration information is used to configure the time domain resources of the second activation time period for the cell to discontinuously transmit DTX, and / or the time domain resources of the third activation time period for the cell to discontinuously receive DRX; the terminal device receives LP-WUS based on the first configuration information, and LP-WUS is used to activate the first activation time period; the terminal device transmits a third signal within the first time period, and the first time period belongs to the first activation time period, but does not belong to the second activation time period or the third activation time period. The terminal device does not receive the first downlink signal in a non-second activation time period, and the terminal device does not send the second uplink signal in a non-third activation time period.

[0009] Among them, the terminal device transmits the third signal within the first time period, and the first time period belongs to the first activation time period, but does not belong to the second activation time period or the third activation time period. It can also be understood that: the priority of the first activation time period is higher than the priority of the second activation time period or the third activation time period. It can also be understood that: the priority of LP-WUS is higher than the priority of cell DTX / DRX.

[0010] Based on the above technical solution, in the scenario where LP-WUS is combined with DTX / DRX, the terminal device can transmit the third signal during the first activation period activated by the low-power wake-up signal, even outside the activation period of the cell DTX or cell DRX. Alternatively, this can be understood as removing the restriction of cell DTX / DRX on signal transmission during the first activation period corresponding to the wake-up signal, taking into account the power consumption of the terminal device, the service experience, and the power consumption of the network equipment.

[0011] In a possible implementation of the first aspect, the third signal includes a third downlink signal and / or a third uplink signal; and the terminal device transmits the third signal within the first time period, including at least one of the following:

[0012] The terminal device receives the third downlink signal within the first time period, and the first time period does not belong to the second activation time period;

[0013] The terminal device sends a third uplink signal within a first time period, and the first time period does not belong to the third activation time period.

[0014] Based on the above technical solution, on the one hand, compared with the prior art, the terminal device cannot receive signals in a non-second activation time period, or the terminal device cannot send signals in a non-second activation time period. In this way, the terminal device can receive the third downlink signal in a time period that does not belong to the second activation time period, or send the third uplink signal in a time period that does not belong to the third activation time period. The experience of the terminal device for delay-sensitive services is guaranteed, and the frequent monitoring of LP-WUS does not significantly increase the receiving power consumption of the terminal device. On the other hand, from the perspective of energy saving of the network device, the network device can also decide whether to wake up the terminal device to serve the terminal device in the cell non-activation time period according to the service type of the terminal device. For example, if the current service of the terminal device is not urgent, the network device can choose not to wake up, but delay the service scheduling to the next cell activation time period. On the contrary, if the current service of the terminal device is more urgent, the network device can choose to wake up immediately and wake up the terminal device through LP-WUS to receive the corresponding service data.

[0015] In a possible implementation of the first aspect, the steps further include: the terminal device not transmitting the fourth signal during a second time period, where the second time period does not fall within the first activation time period but falls within the second activation time period or the third activation time period. This step can also be understood as the terminal device determining not to transmit the fourth signal during the second time period.

[0016] This situation can also be understood as the priority of the first activation time period being lower than the priority of the second activation time period or the third activation time period. It can also be understood as the priority of LP-WUS being lower than the priority of cell DTX / DRX.

[0017] Based on the above technical solution, since the terminal device is already in low-power mode, although the cell is in the DTX activation period, it may be for the services of other terminal devices. Therefore, from the perspective of saving power, this terminal device does not need to transmit the fourth signal. In other words, if the terminal device has services to be transmitted, the network device can continue to extend the previous first activation period or use LP-WUS to wake up the first activation period of the terminal device. Therefore, the benefit of this solution is that the low power consumption of the terminal device is maintained in the second time period.

[0018] In a possible implementation of the first aspect, the fourth signal includes a fourth downlink signal and / or a fourth uplink signal; and the terminal device does not transmit the fourth signal within the second time period, including at least one of the following:

[0019] The terminal device does not receive the fourth downlink signal in the second time period, and the second time period belongs to the second activation time period;

[0020] The terminal device does not send the fourth uplink signal in the second time period, and the second time period belongs to the third activation time period.

[0021] Based on the above technical solution, the terminal device may not receive the fourth downlink signal when it is not in the first activation time period and in the second activation time period, or may not send the fourth uplink signal when it is not in the first activation time period and in the third activation time period. This reduces the power consumption of the terminal device in the second time period and improves the energy saving effect of the terminal device.

[0022] In a possible implementation manner of the first aspect, the above steps further include: receiving a fifth signal within a third time period, where the third time period does not belong to the first activation time period and does not belong to the second activation time period.

[0023] Based on the above technical solution, the terminal device can receive the fifth signal during a third time period that is not part of the first activation time period or the second activation time period. This ensures that both LP-WUS and cell DTX / DRX signals can function, thereby reducing power consumption of the terminal and network equipment. Furthermore, the restrictions imposed by cell DTX / DRX and LP-WUS on certain measurement and synchronization signals are eliminated, ensuring low power consumption while maintaining measurement and synchronization functions.

[0024] The second aspect of the present application provides a communication transmission method, which is executed by a network device, or the method is executed by some components in the network device (such as a processor, chip or chip system, etc.), or the method can also be implemented by a logic module or software that can realize all or part of the network device functions. In the first aspect and its possible implementation, the method is described as being executed by the network device. In this method, the network device sends first configuration information and second configuration information, the first configuration information is used to configure the time domain resources of the first activation time period for the terminal device to receive the low power wake-up signal LP-WUS, and the second configuration information is used to configure the time domain resources of the second activation time period for discontinuous transmission DTX, and / or the time domain resources of the third activation time period for discontinuous reception DRX, the first downlink signal is not received in the non-second activation time period, and the second uplink signal is not sent in the non-third activation time period; the network device sends LP-WUS based on the time domain resources of the first activation time period, and LP-WUS is used to trigger the first activation time period; the network device transmits a third signal in the first time period, and the first time period belongs to the first activation time period, but does not belong to the second activation time period or the third activation time period.

[0025] Based on the above technical solution, in scenarios where LP-WUS is combined with DTX / DRX, the network device can transmit a third signal during the first activation period activated by the low-power wake-up signal, even outside the activation period of the cell DTX or cell DRX. Alternatively, this can be understood as removing the restriction of cell DTX / DRX on signal transmission during the first activation period corresponding to the wake-up signal, thus balancing terminal device power consumption, service experience, and network device power consumption.

[0026] In a possible implementation of the second aspect, the third signal includes a third downlink signal and / or a third uplink signal; and transmitting the third signal within the first time period includes at least one of the following:

[0027] Sending a third downlink signal within a first time period, where the first time period does not belong to the second activation time period;

[0028] A third uplink signal is received within a first time period, and the first time period does not belong to a third activation time period.

[0029] Based on the above technical solution, on the one hand, compared with the prior art, the terminal device cannot receive signals in a non-second activation time period, or the terminal device cannot send signals in a non-second activation time period. In this way, the network device can send a third downlink signal in a time period that does not belong to the second activation time period, or receive a third uplink signal in a time period that does not belong to the third activation time period. The experience of the terminal device for delay-sensitive services is guaranteed, and the frequent monitoring of LP-WUS does not significantly increase the receiving power consumption of the terminal device. On the other hand, the network device can also decide whether to wake up the service terminal device in the cell non-activation time period according to the service type of the terminal device. For example, if the current service of the terminal device is not urgent, the network device can choose not to wake up, but delay the service scheduling to the next cell activation time period. On the contrary, if the current service of the terminal device is more urgent, the network device can choose to wake up immediately and wake up the terminal device through LP-WUS to receive the corresponding service data.

[0030] In a possible implementation of the second aspect, the above steps further include:

[0031] The fourth signal is not transmitted in the second time period, and the second time period does not belong to the first activation time period, but belongs to the second activation time period or the third activation time period.

[0032] Based on the above technical solution, since the terminal device is already in low-power mode, although the cell is in the DTX activation period, it may be for the services of other terminal devices. Therefore, from the perspective of saving power, this terminal device does not need to transmit the fourth signal. In other words, if the terminal device has services to be transmitted, the network device can continue to extend the previous first activation period or use LP-WUS to wake up the first activation period of the terminal device. Therefore, the benefit of this solution is that the low power consumption of the terminal device is maintained in the second time period.

[0033] In a possible implementation of the second aspect, the fourth signal includes a fourth downlink signal and / or a fourth uplink signal; and not transmitting the fourth signal within the second time period includes at least one of the following:

[0034] The fourth downlink signal is not sent in the second time period, and the second time period belongs to the second activation time period;

[0035] The fourth uplink signal is not received in the second time period, and the second time period belongs to the third activation time period.

[0036] Based on the above technical solution, the network device may not send the fourth downlink signal when the device is not in the first activation time period and is in the second activation time period, or may not receive the fourth uplink signal when the device is not in the first activation time period and is in the third activation time period. This reduces the power consumption of the terminal device in the second time period and improves the energy saving effect of the terminal device.

[0037] In a possible implementation manner of the second aspect, the above steps further include: sending a fifth signal within a third time period, where the third time period does not belong to the first activation time period and does not belong to the second activation time period.

[0038] Based on the above technical solution, the network device can send the fifth signal during a third time period that is not part of the first activation time period or the second activation time period. This ensures that LP-WUS and cell DTX / DRX signals can each function to reduce power consumption of the terminal and network device. Furthermore, the restrictions imposed by cell DTX / DRX and LP-WUS on some measurement and synchronization signals are eliminated, ensuring low power consumption while maintaining measurement and synchronization functions.

[0039] The third aspect of the present application provides a communication sending method, which is executed by a network device, or the method is executed by some components in the network device (such as a processor, chip or chip system, etc.), or the method can also be implemented by a logic module or software that can realize all or part of the network device functions. In the first aspect and its possible implementation, the method is described as being executed by a network device. In this method, the network device sends only one type of configuration information, the first configuration information and the second configuration information, the first configuration information is used to configure the time domain resources of the first activation time period for the terminal device to receive the low power wake-up signal LP-WUS, and the second configuration information is used to configure the time domain resources of the third activation time period for the cell to discontinuously send DTX.

[0040] Based on the above technical solution, the network device can configure time domain resources for the terminal device only during the first activation period, or only during the third activation period, thereby reducing the conflict between LP-WUS and cell DTX. Alternatively, the network device can avoid the introduction of complex coexistence rules by not activating LP-WUS and cell DTX at the same time. For example, the network device can balance network device power consumption and service experience by selecting or not waking up the terminal device, with terminal device power consumption primarily guaranteed by the low power mode of LP-WUS.

[0041] In a possible implementation manner of the third aspect, the above steps further include: when the first configuration information is sent, sending third configuration information, where the third configuration information is used to configure time domain resources of a third activation time period of discontinuous reception DRX.

[0042] Based on the above technical solution, the network device can configure the time domain resources of the first activation time period and the time domain resources of the third activation time period for the terminal device, that is, LP-WUS and cell DRX can be configured to take effect at the same time.

[0043] In any possible implementation of any one of the first to third aspects, the first downlink signal and the third downlink signal at least include: a physical downlink control channel (PDCCH) for data scheduling.

[0044] Based on the above technical solution, in the scenario where LP-WUS is combined with cell DTX, during the first time period activated by the low-power wake-up signal, the terminal device must at least receive the PDCCH scheduled for data transmission during the first time period, even if it is outside the cell DTX activation period. This eliminates the restriction of cell DTX / DRX on the data transmission PDCCH in the first activation period corresponding to the wake-up signal, and balances terminal device power consumption, service experience, and network device power consumption.

[0045] In any possible implementation of any one of the first to third aspects, the first downlink signal and the third downlink signal further include at least one of the following: a periodic reference signal CSI-RS for channel state information (CSI) measurement, a semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH), and at least one downlink control information (DCI) carried by the PDCCH in formats 2_0 to 2_5.

[0046] Based on the above technical solution, in the scenario where LP-WUS is combined with cell DTX. Cell DTX can also act on the above-mentioned first downlink signal, that is, the first downlink signal is not sent during the inactive time period of cell DTX, and once LP-WUS wakes up the first active time period, then in the overlapping first time period, the terminal device can receive at least one of the third downlink signals. Accordingly, the network device needs to send the third downlink signal in the first time period. The advantage is that during the first time period awakened by LP-WUS, the network device will wake up to serve the terminal device. Considering that the network device has woken up, other downlink functions can be restored, such as CSI-RS, SPS PDSCH, etc.

[0047] In any possible implementation of any one of the first to third aspects, the above-mentioned second uplink signal and the third uplink signal include at least one of the following: scheduling request (SR), periodic channel state information CSI, SPS CSI, periodic sounding reference signal (SRS), SPS SRS.

[0048] Based on the above technical solution, in the scenario where LP-WUS is combined with cell DRX, similar to the above cell DTX, cell DRX acts on the above second uplink signal, that is, during the inactive period of cell DRX, the network device does not receive and the corresponding terminal device does not send the second uplink signal. Similarly, once LP-WUS wakes up the first time period of the first active period, considering that the network device will wake up to serve the terminal device, since the network device has woken up, it can resume other uplink functions, such as periodic CSI and SRS reporting, SR transmission, etc.

[0049] In any possible implementation of any one of the first to third aspects, the first downlink signal and the fourth downlink signal at least include: a PDCCH for data scheduling.

[0050] Based on the above technical solution, in the scenario where LP-WUS is combined with cell DTX. Since the terminal device is already in low power mode from the perspective of the terminal device, although the cell is in the DTX activation period, it may be for the business of other terminal devices. Therefore, from the perspective of saving power consumption, the terminal device does not need to receive the data transmission PDCCH. In other words, if the terminal device has business to be transmitted, the network device can continue to extend the previous first activation period or use LP-WUS to wake up the first activation period of the terminal device. Therefore, the benefit of this solution is that the low power consumption of the terminal device is maintained in the second time period.

[0051] In any possible implementation of any one of the first to third aspects, the above-mentioned first downlink signal also includes at least one of the following: periodic CSI-RS for CSI measurement, SPS PDSCH, and PDCCH-carried DCI with a format of at least one of 2_0 to 2_5.

[0052] Based on the above technical solution, in the scenario of combining LP-WUS and cell DTX, if the terminal device is not in the first activation time period, in order to keep the terminal power consumption as low as possible, the terminal may not receive at least one of the first downlink signals.

[0053] In any possible implementation of any one of the first to third aspects, the above-mentioned fourth downlink signal also includes at least one of the following: periodic CSI-RS for CSI measurement, SPS PDSCH, and PDCCH-carried DCI with a format of at least one of 2_0 to 2_5.

[0054] Based on the above technical solution, in the scenario of combining LP-WUS and cell DTX, if the terminal device is not in the first activation time period, in order to keep the power consumption of the terminal device as low as possible, the terminal device may not receive at least one of the fourth downlink signals.

[0055] In any possible implementation of any aspect from the first aspect to the third aspect, the above-mentioned fourth downlink signal also includes at least one of the following items: periodic CSI-RS for CSI measurement, and PDCCH-carried DCI with a format of at least one of 2_0 to 2_5; and the fourth downlink signal does not include: SPS PDSCH.

[0056] Based on the above technical solution, the SPS PDSCH is separately proposed, that is, the terminal device needs to receive the SPS PDSCH in the second time period. Considering that the above-mentioned first downlink signals are all signals that can be affected by cell DTX. In the second time period, cell DTX is in an active state. Originally, these signals should not be restricted. However, considering that this is not in the first activation time period corresponding to LP-WUS, downlink signals other than the SPS PDSCH are all non-data transmission signals. In order to minimize the power consumption of the terminal device, they can be not received. However, the SPS PDSCH is also service data, so the terminal device can receive this signal to ensure the service experience.

[0057] In any possible implementation of any one of the first to third aspects, the fourth downlink signal does not include: a PDCCH for data scheduling.

[0058] Based on the above technical solution, in the scenario where LP-WUS is combined with cell DTX, the terminal device can perform operations in the second time period in full accordance with the activated state of cell DTX, that is, the terminal device receives the data transmission PDCCH. Although this consumes more power for the terminal device, it can ensure the service experience as much as possible.

[0059] In any possible implementation of any one of the first to third aspects, the above-mentioned fourth downlink signal does not include at least one of the following: periodic CSI-RS for CSI measurement, SPS PDSCH, and PDCCH-carried DCI with a format of at least one of 2_0 to 2_5.

[0060] Based on the above technical solution, in the scenario where LP-WUS is combined with cell DTX, the terminal device operates in the second time period in accordance with the activated state of cell DTX. That is, in addition to receiving the data transmission PDCCH, the terminal device also receives at least one of the following: periodic CSI-RS for CSI measurement, SPS PDSCH, DCI, etc. Although this consumes more power for the terminal device, it can ensure the service experience as much as possible.

[0061] In any possible implementation of any one of the first to third aspects, the above-mentioned second uplink signal includes at least one of the following: a scheduling request SR, periodic CSI, SPS CSI, periodic SRS, SPS SRS, and an unauthorized physical uplink shared channel (PUSCH).

[0062] Based on the above technical solution, in the scenario where LP-WUS is combined with cell DRX, cell DRX can act on the above second uplink signal, that is, during the inactive period of cell DRX, the terminal device does not send and the network device does not receive the above second uplink signal.

[0063] In any possible implementation of any one of the first to third aspects, the fourth uplink signal does not include at least one of the following: scheduling request SR, periodic CSI, SPS CSI, periodic SRS, SPS SRS, and unauthorized PUSCH.

[0064] Based on the above technical solution, in the scenario where LP-WUS is combined with cell DRX, the terminal device can send these fourth uplink signals in the second time period. Considering that these uplink signals are actionable by cell DRX, and the second time period is an active time period for cell DRX, the terminal device can send these uplink signals. In this case, for these uplink signals, the priority of cell DRX is higher than the first active time period corresponding to LP-WUS.

[0065] In any possible implementation of any one of the first to third aspects, the fourth uplink signal includes at least one of the following: a scheduling request SR, periodic CSI, SPS CSI, a periodic sounding reference signal SRS, SPS SRS, and an unauthorized PUSCH.

[0066] Based on the above technical solution, in the scenario where LP-WUS is combined with cell DRX, the terminal device does not transmit these fourth uplink signals in the second time period. This is equivalent to giving these uplink signals a lower priority than the first active time period corresponding to LP-WUS. Since the first active time period is inactive, to save energy, the terminal device does not transmit these fourth uplink signals, even when cell DRX is active.

[0067] In any possible implementation of any one of the first to third aspects, the above-mentioned fourth uplink signal includes at least one of the following: periodic CSI, SPS CSI, periodic sounding reference signal SRS, SPS SRS; and the fourth uplink signal does not include at least one of the following: scheduling request SR, unauthorized PUSCH.

[0068] Based on the above technical solution, in the scenario where LP-WUS is combined with cell DRX. The terminal device does not send at least one of periodic and SPS CSI, periodic and SPS SRS in the second time period, but can send at least one of SR and unlicensed PUSCH. The reason is that CSI and SRS are auxiliary measurement signals. In order to keep the terminal device in low power mode, they can be not sent when there is no guarantee that there will be business arrival. However, SR and unlicensed PUSCH mean that there is uplink business arrival, so the terminal device can send these uplink signals to ensure business experience.

[0069] In any possible implementation of any one of the first to third aspects, the above-mentioned first downlink signal includes at least one of the following: PDCCH for data scheduling, periodic CSI-RS for CSI measurement, SPS PDSCH, and DCI carried by PDCCH with a format of at least one of 2_0 to 2_5.

[0070] Based on the above technical solution, in the scenario where LP-WUS is combined with cell DTX, since the third time period is inactive for cell DTX, the terminal device does not receive the first downlink signal that can be affected by cell DTX. In other words, only downlink signals that cannot be affected by cell DTX are considered, such as PDCCH for data scheduling, periodic CSI-RS for CSI measurement, SPS PDSCH, and DCI carried by PDCCH in at least one of formats 2_0 to 2_5.

[0071] In any possible implementation of any one of the first to third aspects, the above-mentioned fifth signal includes at least one of the following: CSI-RS for radio resource management (RRM), radio link monitoring (RLM), tracking reference signal (TRS) and beam management, and positioning reference signal (PRS).

[0072] Based on the above technical solution, in the scenario where LP-WUS is combined with cell DTX, cell DTX cannot act on the first downlink signal, while LP-WUS mainly targets real-time scheduling signals such as data transmission PDCCH, so the terminal device can receive these fifth signals.

[0073] In any possible implementation of any one of the first to third aspects, the above-mentioned fifth signal includes at least one of the following: CSI-RS and PRS for RRM, RLM and beam management; and the fifth signal does not include CSI-RS for TRS.

[0074] Based on the above technical solution, in the scenario where LP-WUS is combined with cell DTX, the terminal device can receive the fifth signal, but does not need to receive TRS. This is because TRS is mainly used to maintain relatively frequent time-frequency synchronization for data transmission. Therefore, considering the power consumption of the terminal device, it is best not to receive such relatively short-period signals unless there is guaranteed service arrival.

[0075] In any possible implementation of any one of the first to third aspects, the above-mentioned terminal device is in an RRC connected state.

[0076] Based on the above technical solutions, for the RRC connected state, the above solutions are given considering the combination rules of cell DTX / DRX and LP-WUS.

[0077] In any possible implementation of any one of the first to third aspects, the terminal device is in an IDLE state, and the first downlink signal includes at least one of the following: a synchronization signal, system information, paging information, a common reference signal, and a common PDCCH;

[0078] The second uplink signal includes at least one of the following: random access channel (RACH) information, uplink wake-up information, and an uplink reference signal;

[0079] The third signal includes at least one of the following: paging information and RACH information. Specifically, the third downlink signal includes paging information, and the third uplink signal includes RACH information.

[0080] Based on the above technical solution, the terminal device needs to receive paging information (which may be paging PDCCH and / or paging PDSCH) during the second activation time period, because this may be paging information for the terminal device. However, other signals are basically public signals or broadcast signals, that is, the network device will send them, but the terminal device can choose to receive or not. For example, when the system information has not changed, the terminal device does not need to receive it again in each second activation time period. For another example, the common reference signal is used for measurement. If the terminal device meets the signal or performance requirements, it may not be necessary to perform frequent measurements in each second activation time period.

[0081] Generally, the network device receives the second uplink signal during the third activation period of the cell DRX, while the terminal device chooses to send or not send the second uplink signal based on its own needs. For example, if the terminal device has uplink service needs, it can choose to send RACH information (which can be a random access preamble and / or a random access message, etc.) during the third activation period. For another example, if the terminal device wants to obtain system information, it can choose to send an uplink wake-up signal to the network device to trigger the network device to send the system information.

[0082] Generally speaking, the activation period of cell DTX is relatively long. If the terminal device only receives the third signal during each activation period, the latency will be extended, thus affecting the service experience. Therefore, receiving the third downlink signal during the first time period triggered by LP-WUS (i.e., the inactive time period corresponding to cell DTX) can shorten the reception latency and thus improve the service experience without significantly increasing the terminal device's receiving power consumption.

[0083] Similar to the third downlink signal, the activation period of the cell DDX is relatively long. If the terminal device only sends the third uplink signal (such as RACH information) during each activation period, the access delay will be extended, thereby affecting the service experience. Therefore, sending the third uplink signal during the first time period triggered by LP-WUS (i.e., the inactive time period corresponding to the cell DRX) can shorten the transmission delay and thus improve the service experience without significantly increasing the terminal device's receiving power consumption.

[0084] In any possible implementation of any one of the first to third aspects, the third signal further includes at least one of the following: uplink wake-up information and an uplink reference signal.

[0085] Based on the above technical solution, the network device receives the second uplink signal during the third activation period of the cell DRX, while the terminal device chooses to send or not send the second uplink signal based on its own needs. For example, if the terminal device has uplink service requirements, it can choose to send RACH information (which can be a random access preamble and / or a random access message, etc.) during the third activation period. For another example, if the terminal device wants to obtain system information, it can choose to send an uplink wake-up signal to the network device to trigger the network device to send the system information.

[0165] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application.

[0166] First, some of the terms used in the embodiments of the present application are explained to facilitate understanding by those skilled in the art.

[0167] 1. Transmission

[0168] Transmission refers to the communication process between a network device and a terminal device. In the embodiments of the present application, transmission includes sending and / or receiving. That is, transmission can be sending, receiving, or both sending and receiving, and the specific details are not limited here.

[0169] In addition, receiving can also be understood as detecting, monitoring, etc., which is not limited here. For example, receiving DCI generally refers to monitoring DCI.

[0170] 2. Radio Resource Control (RRC) Status

[0171] There are at least three RRC states for terminal devices: RRC connected state (connected state), RRC idle state (idle state) and inactive state (inactive state).

[0172] RRC connected state: The terminal device has established an RRC connection with the network, enabling data transmission. The RRC connected state can also be referred to as the connected state. In this document, "connected state" and "RRC connected state" are the same concept and can be referred to interchangeably.

[0173] RRC Idle State: The terminal device has not established an RRC connection with the network, and the base station has not stored the context of the terminal device. If the terminal device needs to enter the RRC Connected State from the RRC Idle State, it needs to initiate the RRC connection establishment process. The RRC Idle State can also be referred to as the Idle State. In this article, "Idle State" and "RRC Idle State" are the same concept and can be referred to interchangeably.

[0174] RRC inactive state: The terminal device has previously entered the RRC connected state, and then the base station released the RRC connection, but the base station saved the context of the terminal device. If the terminal device needs to enter the RRC connected state again from the RRC inactive state, it is necessary to initiate an RRC recovery process (or called an RRC connection recovery process). Compared with the RRC establishment process, the RRC recovery process has a shorter delay and lower signaling overhead. However, the base station needs to save the context of the terminal device, which will occupy the storage overhead of the base station. The RRC inactive state can also be referred to as the inactive state. In this article, "deactivated state", "deactivated state", "inactive state", "RRC inactive state" and "RRC deactivated state" are the same concept, and these names can be interchanged.

[0175] 3. Configuration and pre-configuration

[0176] In this application, configuration and pre-configuration are used simultaneously. Configuration refers to the network device / server sending some parameter configuration information or parameter values ​​to the terminal through messages or signaling, so that the terminal can determine the communication parameters or resources during transmission based on these values ​​or information. Pre-configuration is similar to configuration and can be parameter information or parameter values ​​pre-negotiated between the network device / server and the terminal device, parameter information or parameter values ​​used by the base station / network device or terminal device as specified in the standard protocol, or parameter information or parameter values ​​pre-stored in the base station / server or terminal device. This application does not limit this.

[0177] Furthermore, these values ​​and parameters can be changed or updated.

[0178] 4. The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "At least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can mean the following situations: A exists alone, B exists alone, and A and B exist at the same time, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B and / or C" can mean: A exists alone, B exists alone, C exists alone, A and B exist at the same time, A and C exist at the same time, B and C exist at the same time, and A, B and C exist at the same time. In addition, unless otherwise specified, the ordinal numbers "first" and "second" mentioned in the embodiments of the present application are used to distinguish multiple objects and are not used to limit the order, timing, priority or importance of multiple objects.

[0179] In this application, unless otherwise specified, the same or similar parts between the various embodiments can refer to each other. In the various embodiments of this application, and the various methods / designs / implementations in each embodiment, if there is no special explanation and logical conflict, the terms and / or descriptions between different embodiments and the various methods / designs / implementations in each embodiment are consistent and can be referenced to each other. The technical features in different embodiments and the various methods / designs / implementations in each embodiment can be combined to form new embodiments, methods, or implementations according to their inherent logical relationships. The following description of the implementation methods of this application does not constitute a limitation on the scope of protection of this application.

[0180] Please refer to Figure 1A, which is a schematic diagram of the architecture of a communication system 1000 used in an embodiment of the present application. As shown in Figure 1A, the communication system includes a radio access network (RAN) 100 and a core network 200. Optionally, the communication system 1000 may also include the Internet 300. The RAN 100 includes at least one RAN node (such as 110a and 110b in Figure 1A, collectively referred to as 110), and may also include at least one terminal (such as 120a-120j in Figure 1A, collectively referred to as 120). The RAN 100 may also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in Figure 1A). The terminal 120 is connected to the RAN node 110 via a wireless connection, and the RAN node 110 is connected to the core network 200 via a wireless or wired connection. The core network equipment in the core network 200 and the RAN node 110 in the RAN 100 can be independent and different physical devices, or they can be the same physical device that integrates the logical functions of the core network equipment and the logical functions of the RAN node. Terminals and RAN nodes may be connected to each other via wired or wireless means.

[0181] The RAN 100 may be an Evolved Universal Terrestrial Radio Access (E-UTRA) system, a NR system, or a future radio access system defined in 3GPP. The RAN 100 may also include two or more of the aforementioned different radio access systems. The RAN 100 may also be an open RAN (O-RAN).

[0182] A RAN node, also known as a radio access network device, RAN entity, or access node, is used to help terminals access a communication system wirelessly. In one application scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a fifth-generation (5G) mobile communication system, a next-generation base station in a sixth-generation (6G) mobile communication system, or a base station in a future mobile communication system. A RAN node can be a macro base station (such as 110a in Figure 1A), a micro base station, or an indoor station (such as 110b in Figure 1A), or a relay node or a donor node.

[0183] In another application scenario, multiple RAN nodes can collaborate to help terminals achieve wireless access, with different RAN nodes implementing portions of the base station's functions. For example, a RAN node can be a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). The CU implements the base station's radio resource control protocol and packet data convergence protocol (PDCP) functions, as well as the service data adaptation protocol (SDAP) functions. The DU implements the base station's radio link control layer and medium access control (MAC) layer functions, as well as some or all of the physical layer functions. For detailed descriptions of each of the above protocol layers, please refer to the relevant 3GPP technical specifications. The RU can be used to implement the transmission and reception of radio frequency signals. The CU and DU can be two independent RAN nodes, or they can be integrated into the same RAN node, such as in a baseband unit (BBU). The RU can be included in radio frequency equipment, such as a remote radio unit (RRU) or an active antenna unit (AAU). The CU can be further divided into two types of RAN nodes: CU-control plane and CU-user plane.

[0184] In different systems, RAN nodes may have different names. For example, in an O-RAN system, the CU may be called an open CU (O-CU), the DU may be called an open DU (O-DU), and the RU may be called an open RU (O-RU). The RAN nodes in the embodiments of the present application may be implemented by software modules, hardware modules, or a combination of software modules and hardware modules. For example, the RAN node may be a server loaded with the corresponding software module. The embodiments of the present application do not limit the specific technology and specific device form used by the RAN node.

[0185] In addition, a RAN node can also be referred to as a network device. A network device is a device deployed in a radio access network to provide wireless communication functions for terminal devices. Network devices may include various forms of macro base stations, micro base stations (also known as small stations), relay stations, access points, etc. In systems using different radio access technologies, the names of network devices may be different, such as eNB or eNodeB (evolutionary NodeB) in Long Term Evolution (LTE). A network device may also be a wireless controller in a cloud radio access network (CRAN) scenario. A network device may also be a base station device in a future 5G network or a network device in a future evolved PLMN network. A network device may also be a wearable device or an in-vehicle device. A network device may also be a transmission and reception point (TRP). In addition, in a network structure, a network device may include a centralized unit (CU) node, a distributed unit (DU) node, or a RAN device including a CU node and a DU node. For ease of description, the following description uses a base station as an example of a RAN node.

[0186] A terminal is a device with wireless transceiver capabilities that can send signals to a base station or receive signals from a base station. A terminal may also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal, etc. Terminals can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. A terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, wearable device, vehicle, airplane, ship, robot, robotic arm, smart home device, etc. The embodiments of this application do not limit the specific technology and specific device form adopted by the terminal.

[0187] Base stations and terminals can be fixed or mobile. They can be deployed on land, indoors or outdoors, handheld or vehicle-mounted; on water; or on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of base stations and terminals.

[0188] The roles of base stations and terminals can be relative. For example, the helicopter or drone 120i in Figure 1A can be configured as a mobile base station. To terminals 120j accessing the wireless access network 100 via 120i, terminal 120i is a base station. However, to base station 110a, 120i is a terminal, meaning that communication between 110a and 120i occurs via a wireless air interface protocol. Of course, communication between 110a and 120i can also occur via a base station-to-base station interface protocol. In this case, 120i is also a base station relative to 110a. Therefore, base stations and terminals can be collectively referred to as communication devices. 110a and 110b in Figure 1A can be referred to as communication devices with base station functionality, while 120a-120j in Figure 1A can be referred to as communication devices with terminal functionality.

[0189] Communication between base stations and terminals, between base stations, and between terminals can be carried out through authorized spectrum, unauthorized spectrum, or both; communication can be carried out through spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or spectrum below 6 GHz and spectrum above 6 GHz. The embodiments of the present application do not limit the spectrum resources used for wireless communication.

[0190] In the embodiments of the present application, the functions of the base station may also be performed by a module (such as a chip) in the base station, or by a control subsystem that includes the base station functions. The control subsystem that includes the base station functions here may be a control center in the above-mentioned application scenarios such as smart grid, industrial control, smart transportation, and smart city. The functions of the terminal may also be performed by a module (such as a chip or modem) in the terminal, or by a device that includes the terminal functions.

[0191] It can be understood that the RAN 100 described above includes at least one RAN node (such as 110 a and 110 b in FIG. 1A , collectively referred to as 110 ), and may also include at least one terminal (such as 120 a - 120 j in FIG. 1A , collectively referred to as 120 ).

[0192] In one possible implementation, the communication system shown in FIG1A may also be as shown in FIG1B , that is, including a RAN node 110 and multiple terminals (such as 120A and 120B in FIG1B ). In this case, a single RAN node can transmit data or control signaling to a single terminal or multiple terminals.

[0193] In another possible implementation, the communication system shown in FIG1A may also be shown in FIG1C , that is, include multiple RAN nodes (such as 110A, 110B, and 110C in FIG1C ) 110 and a terminal 120. In this case, multiple RAN nodes may also simultaneously transmit data or control signaling for a single terminal.

[0194] As wireless communications have larger bandwidths and more antennas, energy saving for base stations and terminals is a hot topic in wireless communications.

[0195] One technical feature of base station energy conservation is cell DTX / DRX. The basic idea is that the base station only sends and receives certain signals within periodic time windows, that is, it does not receive or send these signals outside the above time windows.

[0196] For example, as shown in FIG2 , the base station transmits data only within the cell DTX / DRX on window in the cell DTX / DRX cycle, and does not transmit data during the cell DTX / DRX off time period in the cell DTX / DRX cycle, thereby achieving energy saving for the base station.

[0197] One technical feature of terminal energy conservation is a mechanism based on the reception of wake-up signals. The basic idea is that the terminal periodically detects wake-up signals. Once a wake-up signal triggers the terminal to start receiving, the terminal will receive certain signals within the period corresponding to the wake-up signal. Otherwise, the terminal will not receive these signals. Terminal energy conservation is also called connected-discontinuous reception (C-DRX).

[0198] Optionally, a terminal configured with a low power wake-up signal (LP-WUS) adopts a primary and secondary receiving link combined mode, wherein the primary link is in an ultra-deep sleep state before being awakened by the LP-WUS.

[0199] For example, as shown in Figure 3, the terminal detects the wake-up signal within the wake-up signal detection period. If the terminal does not receive the wake-up signal, the terminal is not activated to receive data. If the terminal receives the wake-up signal, the terminal is triggered to start receiving and receive data within the activated terminal receiving time period.

[0200] When both base station and terminal energy conservation are implemented simultaneously, PDCCH reception can only be performed during the intersection of the cell DTX activation window and the terminal C-DRX activation window. In summary, the main limitation is that during the cell DTX inactive period, the terminal cannot receive the PDCCH, even if the terminal C-DRX is active. Furthermore, during the cell DRX inactive period, the base station cannot receive the terminal's uplink transmission. Therefore, in the scenario where LP-WUS is combined with DTX / DRX, how to reduce transmission restrictions while ensuring energy conservation is a pressing technical issue to be addressed.

[0201] For example, as shown in Figure 4, once a longer cell DTX / DRX cycle is configured, even if the low-power wake-up signal can wake up the corresponding receiving time window in time, it will be limited by the activation time period of the cell DTX / DRX, resulting in the terminal still being unable to receive the PDCCH scheduled for data transmission in time.

[0202] To address the above technical issues, embodiments of the present application provide a communication method and related devices. In a scenario where LP-WUS is combined with DTX / DRX, a terminal device can transmit a third signal during a first activation period activated by a low-power wake-up signal, even outside the activation period of cell DTX or cell DRX. Alternatively, this can be understood as removing the restriction of cell DTX / DRX on signal transmission during the first activation period corresponding to the wake-up signal, thereby balancing terminal power consumption, service experience, and base station power consumption.

[0203] The communication method provided in the embodiments of the present application is described below. The method can be executed by a terminal device / network device, or by a component of the terminal device / network device (such as a processor, chip, or chip system). Of course, the method can also be executed by a system consisting of a network device and a terminal device.

[0204] Please refer to Figure 5, which is a flow chart of a communication method provided in an embodiment of the present application. The method may include steps 501 to 503. Steps 501 to 503 can be performed by a terminal device or a network device, or by some components in the terminal device or the network device (such as a processor, a chip or a chip system, etc.), or by a logic module or software that can realize all or part of the functions of the terminal device. The following description is taken as an example of execution by a terminal device or a network device. The processing performed by a single execution subject in steps 501 to 503 can also be divided into executions by multiple execution subjects, and these execution subjects can be logically and / or physically separated. For example, the processing performed by the network device can be divided into executions by at least one of the CU, DU and RU. Steps 501 to 503 are described in detail below.

[0205] Step 501: The terminal device obtains first configuration information and second configuration information.

[0206] In an embodiment of the present application, there are multiple ways for a terminal device to obtain the first configuration information and the second configuration information. The ways may be receiving the first configuration information and the second configuration information sent by a network device, or the first configuration information and the second configuration information pre-stored by the terminal device, or pre-configured, etc., which are not limited here.

[0207] In the embodiment of the present application, the first configuration information is used to configure the time domain resources of the first activation time period for the terminal device to receive LP-WUS, and the second configuration information is used to configure the time domain resources of the second activation time period of the cell DTX, and / or the time domain resources of the third activation time period of the cell DRX.

[0208] Optionally, the first configuration information may also be used to configure frequency domain resources of a first activation time period for receiving LP-WUS by the terminal device, which may specifically include a period and a time-frequency starting position.

[0209] Furthermore, if a specific sequence is used to generate a binary on-off keying (OOK) waveform, sequence information may also be configured. OOK may also be referred to as binary amplitude shift keying (2ASK).

[0210] In addition, the terminal device does not receive the first downlink signal in a non-second activation time period, and the terminal device does not send the second uplink signal in a non-third activation time period. It can be understood that: the terminal device receives the first downlink signal in the second activation time period, and the terminal device sends the second uplink signal in the third activation time period.

[0211] Optionally, the terminal device receives the first configuration information and the second configuration information sent by the network device. Correspondingly, the network device sends the first configuration information and the second configuration information to the terminal device.

[0212] Furthermore, for a terminal device in an RRC connected state, the LP-WUS is primarily used to wake up the corresponding first activation time period, allowing the terminal device to receive the PDCCH scheduled for data transmission within the first activation time period. Conversely, if the terminal device is not awakened, the terminal device can skip the first activation time period, i.e., it does not need to receive the PDCCH scheduled for data transmission.

[0213] It is understandable that the activation time period in the embodiment of the present application may also be referred to as an activation time window or an activation window, etc., which is not specifically limited here.

[0214] Step 502: The network device sends an LP-WUS to the terminal device.

[0215] The network device sends an LP-WUS to the terminal device, and correspondingly, the terminal device receives the LP-WUS sent by the network device. The LP-WUS is used to activate the first time period, or it can be understood that the LP-WUS is used to trigger the first activation time period.

[0216] Optionally, when the network device configures the first configuration information for the terminal device, the network device sends the LP-WUS based on the time domain resources of the first activation time period, and accordingly, the terminal device receives the LP-WUS based on the first configuration information. Specifically, the terminal device determines the time domain resources and / or frequency domain resources for receiving the LP-WUS based on the first configuration information, and then the terminal device receives the LP-WUS sent by the network device on the time domain resources and / or frequency domain resources for receiving the LP-WUS.

[0217] For example, the first activation time period may be the activation terminal reception time period in FIG. 3 .

[0218] In addition, the moment when the terminal device receives the LP-WUS may be the same as or different from the start moment of its corresponding first activation time period.

[0219] Optionally, there may be a certain time domain offset between the moment when the terminal device receives LP-WUS and the start moment of its corresponding first activation time period, such as the processing time of LP-WUS, the switching time to a normal receiver (or called a main receiver, main link receiver, etc.), etc. The time domain offset can be predefined or notified to the terminal device through signaling, and is not limited here.

[0220] In one possible implementation, the first activation time period is predefined or notified to the terminal device in advance through signaling. In this case, once the LP-WUS triggers the first activation time period, the terminal device receives the PDCCH during the first activation time period. Then, after the first activation time period expires, it enters the low power mode again, or receives a specific indication signaling from the network device to enter the low power mode again. For example, the length of the first activation time period can also be configured to be infinite, which means that as long as the above-mentioned specific indication signaling is not received, the terminal device remains in normal receiver mode to receive signals such as PDCCH.

[0221] In another possible implementation, the first activation time period includes a basic activation time period and an extended activation time period, and the two may overlap or not overlap. In this case, the basic activation time period is defined as the first activation time period above. If LP-WUS triggers the first activation time period, but the terminal device does not receive PDCCH within the basic activation time period, then the basic activation time period will enter the low power consumption mode again after the expiration of the basic activation time period. If the terminal device receives PDCCH within the basic activation time period (as shown in Figure 6), the timer of the extended activation time period will be immediately started, and the PDCCH will continue to be received while this timer has not returned to zero (i.e., within the extended activation time period). And each time a PDCCH is received, the above timer will be reset (i.e., the extended activation time period will be restarted) until the timer returns to zero, and the terminal device will enter the low power consumption mode again.

[0222] It should be noted that both the basic activation time period and the extended activation time period are counted as the first activation time period triggered by the LP-WUS or the corresponding time period in the embodiments of the present application. In fact, the extended activation time period is strictly speaking extended by using a timer after the LP-WUS triggers activation and receives a PDCCH again. However, the embodiments of the present application believe that it is fundamentally the initial LP-WUS that activates the basic activation time period, and the PDCCH is received within the basic activation time period to obtain the extended activation time period. Therefore, for convenience in the embodiments of the present application, unless otherwise specified, they are all counted as the first activation time period triggered by the LP-WUS or the corresponding time period.

[0223] Step 503: The network device and the terminal device transmit a third signal within the first time period.

[0224] In the embodiment of the present application, the first time period belongs to the first activation time period, but does not belong to the second activation time period or the third activation time period. That is, the first activation time period triggers LP-WUS, but does not trigger the second activation time period of cell DTX, or the third activation time period does not trigger cell DRX.

[0225] In the embodiment of the present application, the situation in which the network device and the terminal device transmit the third signal within the first time period includes at least one of the following: transmitting a third uplink signal, transmitting a third downlink signal, that is, the terminal device sends a third uplink signal to the network device, and the network device sends a third downlink signal to the terminal device. Alternatively, it can be understood that the situation in which the network device and the terminal device transmit the third signal within the first time period includes at least one of the following: a scenario in which LP-WUS is combined with cell DTX, and a scenario in which LP-WUS is combined with cell DRX. The following are described separately:

[0226] The first case is the scenario where LP-WUS is combined with cell DTX.

[0227] In this case, this step includes: the terminal device receives the third downlink signal in the first time period, the first time period belongs to the first activation time period and does not belong to the second activation time period. Accordingly, the network device sends the third downlink signal in the first time period.

[0228] This situation can also be understood as the priority of the first activation time period being higher than the priority of the second activation time period. It can also be understood as the priority of LP-WUS being higher than the priority of cell DTX. It can also be understood as the first time period being the time period within the first activation time period excluding the second activation time period. It can also be understood as the first activation time period corresponding to LP-WUS being active, while the second activation time period corresponding to cell DTX being inactive.

[0229] Optionally, the terminal device receives the third downlink signal sent by the network device within the first time period. Correspondingly, the network device sends the third downlink signal to the terminal device within the first time period.

[0230] In Example 1, the first downlink signal and the third downlink signal include at least: a PDCCH for data scheduling, etc. This example can resolve the conflict between LP-WUS and the cell DTX mechanism. As shown in Figure 7, compared to the impact of Figure 4 on service latency, the solution of Figure 7 ensures the terminal device's experience of delay-sensitive services, and the frequent monitoring of LP-WUS does not significantly increase the terminal device's receiving power consumption. In addition, from the perspective of network device energy saving, the network device can also decide whether to wake up to serve the terminal device during the cell inactive period based on the terminal device's service type. For example, if the terminal device's current service is not urgent, the network device may choose not to wake up and instead delay service scheduling until the next cell active period. Conversely, if the terminal device's current service is more urgent, the network device may choose to wake up immediately and use LP-WUS to wake up the terminal device to receive the PDCCH and corresponding service data. In summary, the embodiments of the present application eliminate the problem of cell DTX / DRX restricting transmission during the active period corresponding to the wake-up signal in existing mechanisms, while taking into account aspects such as terminal device power consumption, service experience, and network device power consumption.

[0231] It should be noted that the signal mentioned in the above example includes a channel, which can be understood as a signal including a signal carried on the channel. For example, the first downlink signal includes a PDCCH for data scheduling, which can be understood as the first downlink signal including a signal carried on the PDCCH for data scheduling.

[0232] Example 2: The first downlink signal and the third downlink signal also include at least one of the following: periodic CSI-RS for CSI measurement, SPS PDSCH, PDCCH carrying at least one DCI in the format of 2_0 to 2_5, etc. Specifically, the cell DTX can also act on the above-mentioned first downlink signal, that is, these first downlink signals are not sent during the non-activation period of the cell DTX. Once the LP-WUS wakes up the first activation period, the terminal device can receive at least one of these third downlink signals in the overlapping first period. Accordingly, the network device needs to send these corresponding signals in the first period. The advantage is that during the first period awakened by the LP-WUS, the network device will wake up the serving terminal device. Considering that the network device has woken up, other downlink functions except the data transmission PDCCH can be restored, such as CSI-RS, SPS PDSCH, PDCCH carrying at least one DCI in the format of 2_0 to 2_5, etc.

[0233] It should be noted that the above-mentioned Example 1 and Example 2 may exist independently or in combination. For example, not only the data transmission PDCCH in Example 1 but also other downlink signals in Example 2 may be considered.

[0234] It should be understood that Examples 1 and 2 above are described using the example that the first downlink signal and the third downlink signal are identical. In actual applications, the first downlink signal and the third downlink signal may also differ, and this is not limited to this. For example, the third downlink signal may be a portion of the first downlink signal, such as a higher-priority signal.

[0235] In addition, the above-mentioned Example 1 and Example 2 are merely examples of commonly used downlink signals. In actual applications, the first downlink signal and the third downlink signal may also be other situations, which are not specifically limited here.

[0236] The second case is the scenario where LP-WUS is combined with cell DRX.

[0237] In this case, this step includes: the terminal device sends the third uplink signal in the first time period, the first time period belongs to the first activation time period and does not belong to the third activation time period. Accordingly, the network device receives the third uplink signal in the first time period.

[0238] This situation can also be understood as the priority of the first activation time period being higher than the priority of the third activation time period. It can also be understood as the priority of the LP-WUS being higher than the priority of the cell DRX. It can also be understood as the first time period being the first activation time period excluding the third activation time period. It can also be understood as the first activation time period corresponding to the LP-WUS being active, while the third activation time period corresponding to the cell DRX being inactive.

[0239] Optionally, the terminal device sends a third uplink signal to the network device within the first time period. Correspondingly, the network device receives the third uplink signal sent by the terminal device within the first time period.

[0240] Example 3: The second uplink signal and the third uplink signal include at least one of the following: SR, periodic CSI, SPS CSI, periodic SRS, SPS SRS, etc. Similar to the cell DTX in the first case mentioned above, the cell DRX acts on the above-mentioned second uplink signal, that is, the network device does not receive and the corresponding terminal device does not send the second uplink signal during the inactive time period of the cell DRX. Similarly, once the LP-WUS wakes up the first time period in the first active time period, considering that the network device will wake up to serve the terminal device, since the network device has woken up, other uplink functions can be restored, such as periodic CSI and SRS reporting, SR sending, etc.

[0241] It is understood that Example 3 above is merely an example in which the second uplink signal and the third uplink signal are identical. In actual applications, the second uplink signal and the third uplink signal may also differ, and the specific details are not limited here. For example, the third downlink signal may be a portion of the second downlink signal, such as a higher priority signal.

[0242] In addition, the above example 3 is only an example of a commonly used uplink signal. In actual applications, the second uplink signal and the third uplink signal may also be other situations, which are not specifically limited here.

[0243] It should be noted that the first and second situations described above can exist independently (i.e., a scenario in which LP-WUS is combined with cell DTX, or a scenario in which LP-WUS is combined with cell DRX), or can exist simultaneously (i.e., LP-WUS can exist simultaneously with cell DTX and cell DRX). Specific limitations are not given here.

[0244] In addition, the above examples 1 to 3 are examples for the terminal device in the RRC connected state. The following examples are given of various signals when the terminal device is in the RRC idle state (also called IDLE state).

[0245] Example 4, the first downlink signal includes at least one of the following: synchronization signal, system information, paging information, common reference signal, common PDCCH. Generally, the network device sends these first downlink signals in the second activation time period of the cell DTX, and whether the terminal device receives these signals during this time period needs to be discussed separately. Specifically, the terminal device needs to receive paging information (which may be paging PDCCH and / or paging PDSCH) during the second activation time period, because this may be paging information for the terminal device. But other signals are basically public signals or broadcast signals, that is, the network device will send them, but the terminal device can choose to receive them or not. For example, when the system information has not changed, the terminal device does not need to receive it again in each second activation time period. For another example, the common reference signal is used for measurement. If the terminal device meets the signal or performance requirements, it may not be necessary to perform measurements frequently in each second activation time period.

[0246] Example 5, the second uplink signal includes at least one of the following: random access channel RACH information, uplink wake-up information, and uplink reference signal. Generally, the network device receives these second uplink signals in the third activation time period of the cell DRX, and the terminal device chooses to send or not send these second uplink signals based on its own needs. For example, if the terminal device has uplink service needs, it can choose to send RACH information (which can be a random access preamble and / or a random access message, etc.) in the third activation time period. For another example, if the terminal device wants to obtain system information, it can choose to send an uplink wake-up signal to the network device to trigger the network device to send system information.

[0247] Example 6: The third signal includes at least one of the following: paging information, RACH information.

[0248] In the case where the third signal includes paging information, the activation period of the cell DTX is generally long. If the terminal device only receives the third signal during each activation period, the latency will be extended, thereby affecting the service experience. Therefore, receiving the third downlink signal during the first time period triggered by LP-WUS (i.e., the inactive time period corresponding to the cell DTX) can shorten the reception latency and thus improve the service experience without significantly increasing the receiving power consumption of the terminal device.

[0249] When the third signal includes RACH information, similar to the third downlink signal, the cell DRX activation period is relatively long. If the terminal device only sends the third uplink signal (such as RACH information) during each activation period, the access delay will be extended, thereby affecting the service experience. Therefore, sending the third uplink signal during the first time period triggered by LP-WUS (i.e., the inactive time period corresponding to the cell DRX) can shorten the transmission delay and thus improve the service experience without significantly increasing the terminal device's receiving power consumption.

[0250] Furthermore, the third signal may also include at least one of the following: uplink wake-up information and an uplink reference signal.

[0251] It should be noted that the above-mentioned Examples 4 to 6 may exist independently, or at least two of Examples 4 to 6 may exist simultaneously. Specific details are not limited here.

[0252] In an embodiment of the present application, in a scenario where LP-WUS is combined with DTX / DRX, a terminal device may transmit a third signal during the first activation period activated by a low-power wake-up signal, even outside the activation period of cell DTX or cell DRX. Alternatively, this can be understood as removing the restriction of cell DTX / DRX on signal transmission during the first activation period corresponding to the wake-up signal, thereby balancing terminal device power consumption, service experience, and network device power consumption.

[0253] For ease of understanding, the following takes the complete alignment of the second activation time period of cell DTX with the third activation time period of cell DRX as an example to introduce the various time periods involved in the embodiments of the present application, such as the first time period in step 503, and the subsequent optional second time period and third time period.

[0254] For example, as shown in Figure 8, in the low-power wake-up mechanism, the terminal device triggers the first activation period after receiving the LP-WUS. In the cell DTX / DRX mechanism, cell DTX corresponds to the second activation period, and cell DRX corresponds to the third activation period, which are collectively referred to as the second / third activation period.

[0255] The first time period belongs to the first activation time period, but does not belong to the second activation time period or the third activation time period. The first time period may also be referred to as LP-on + cell-off. LP-on corresponds to the first activation time period in which LP-WUS is triggered, and cell-off corresponds to the second activation time period in which cell DTX is not triggered, and / or the third activation time period in which cell DRX is not triggered.

[0256] The second time period does not belong to the first activation time period, but rather to the second or third activation time period. This can also be understood as the first activation time period corresponding to LP-WUS being inactive, while the second / third activation time period corresponding to cell DTX / DRX being active. The second time period can also be referred to as LP-off + cell-on. LP-off corresponds to the first activation time period when LP-WUS is not triggered, and cell-on corresponds to the second activation time period when cell DTX is triggered, and / or the third activation time period when cell DRX is triggered.

[0257] The third time period does not belong to the first activation time period, nor does it belong to the second activation time period. This can also be understood as the first activation time period corresponding to LP-WUS being inactive, while the second / third activation time periods corresponding to cell DTX / DRX being inactive. The third time period can also be referred to as LP-off + cell-off. LP-off corresponds to the first activation time period when LP-WUS is not triggered, and cell-off corresponds to the second activation time period when cell DTX and / or cell DRX are not triggered.

[0258] The fourth time period belongs to both the first activation time period and the second activation time period. This can also be understood as the first activation time period corresponding to LP-WUS being active, while the second / third activation time periods corresponding to cell DTX / DRX being active. The third time period can also be referred to as LP-on + cell-on. LP-on corresponds to the first activation time period that triggers LP-WUS, and cell-on corresponds to the second activation time period that triggers cell DTX and / or the third activation time period that triggers cell DRX.

[0259] It is understandable that the second / third activation time periods of the cell shown in Figure 8 are only examples. In actual applications, cell DTX and cell DRX can be configured independently, or even only one of them can be configured. When the activation time periods of the two are not aligned, such as completely non-overlapping or partially overlapping, the embodiments of the present application are still applicable, because Figure 8 is only for ease of understanding and only considers the combination rules of LP-WUS extreme with cell DTX and DRX, respectively, and has no direct relationship with various configurations between cell DTX and DRX. Other situations of the second / third activation time period of the cell are not limited here.

[0260] The communication between the network device and the terminal device in the second time period will be described below in conjunction with Figure 9. The communication between the network device and the terminal device in the third time period will be described below in conjunction with Figure 10.

[0261] Please refer to Figure 9, which is another flow chart of the communication method provided in an embodiment of the present application. The method may include step 901. Step 901 can be performed by a terminal device or a network device, or by some components in the terminal device or the network device (such as a processor, a chip or a chip system, etc.), or by a logic module or software that can realize all or part of the terminal device functions. The following description is taken as an example of execution by a terminal device or a network device. The processing performed by a single execution subject in step 901 can also be divided into executions by multiple execution subjects, and these execution subjects can be logically and / or physically separated. For example, the processing performed by the network device can be divided into executions by at least one of the CU, DU and RU. Step 901 is described in detail below.

[0262] Step 901: The network device and the terminal device do not transmit a fourth signal within a second time period.

[0263] The network device and the terminal device do not transmit the fourth signal within the second time period, which can also be understood as: the network device and / or the terminal device determines not to transmit the fourth signal within the second time period.

[0264] In the embodiment of the present application, the second time period does not belong to the first activation time period, but belongs to the second activation time period or the third activation time period. That is, the first activation time period does not trigger LP-WUS, but the second activation time period triggers cell DTX, and / or the third activation time period triggers cell DRX.

[0265] In the embodiment of the present application, the situation in which the network device and the terminal device do not transmit the fourth signal in the second time period includes at least one of the following: not transmitting the fourth uplink signal, not transmitting the fourth downlink signal, that is, the terminal device does not send the fourth uplink signal to the network device, and the network device does not send the fourth downlink signal to the terminal device. Alternatively, it can be understood that the situation in which the network device and the terminal device do not transmit the fourth signal in the second time period includes at least one of the following: a scenario in which LP-WUS is combined with cell DTX, and a scenario in which LP-WUS is combined with cell DRX. They are described below respectively:

[0266] The first case is the scenario where LP-WUS is combined with cell DTX.

[0267] In this case, this step includes: the terminal device not receiving the fourth downlink signal during the second time period. Alternatively, the terminal device determines not to receive the fourth downlink signal during the second time period. The second time period does not fall within the first activation time period, but falls within the second activation time period. Accordingly, the network device does not send the fourth downlink signal during the second time period.

[0268] This situation can also be understood as the priority of the first activation time period being lower than the priority of the second activation time period. It can also be understood as the priority of LP-WUS being lower than the priority of cell DTX. It can also be understood as the second time period being the second activation time period excluding the first activation time period. It can also be understood as the first activation time period corresponding to LP-WUS being inactive, while the second activation time period corresponding to cell DTX being active.

[0269] Optionally, the terminal device does not receive the fourth downlink signal sent by the network device in the second time period. Correspondingly, the network device does not send the fourth downlink signal to the terminal device in the first time period.

[0270] Example 7, the first downlink signal and the fourth downlink signal include at least: PDCCH for data scheduling, etc. This example can solve the problem of conflict between LP-WUS and the cell DTX mechanism. Since it is already in low power mode from the perspective of the terminal device, although the cell is in the DTX activation time period, it may be for the business of other terminal devices. Therefore, from the perspective of saving power consumption, this terminal device does not need to receive the data transmission PDCCH. In other words, if the terminal device has business to be transmitted, the network device can continue to extend the previous first activation time period or use LP-WUS to wake up the first activation time period of the terminal device. Therefore, the benefit of this solution is that the low power consumption of the terminal device is maintained in the second time period.

[0271] In Example 8, the first downlink signal and the fourth downlink signal further include at least one of the following: a periodic CSI-RS for CSI measurement, an SPS PDSCH, and at least one DCI in formats 2_0 to 2_5 carried by a PDCCH. Although these signals are not subject to the cell DTX restriction at this time, they are not in the first activation time period of the terminal device. In order to minimize the power consumption of the terminal, the terminal may not receive at least one of these fourth downlink signals.

[0272] In Example 9, the first downlink signal includes at least one of the following: a periodic CSI-RS for CSI measurement, an SPS PDSCH, and at least one DCI formatted in 2_0 to 2_5 carried by a PDCCH. The fourth downlink signal also includes at least one of the following: a periodic CSI-RS for CSI measurement, and at least one DCI formatted in 2_0 to 2_5 carried by a PDCCH. However, the fourth downlink signal does not include the SPS PDSCH. In this example, the SPS PDSCH is singled out, meaning that the terminal device needs to receive the SPS PDSCH in the second time period. Considering that the aforementioned first downlink signals are all signals that can be affected by cell DTX, and that cell DTX is active in the second time period, these signals should not be restricted. However, considering that this is not the first activation time period corresponding to the LP-WUS, downlink signals other than the SPS PDSCH are non-data transmission signals. To minimize terminal device power consumption, they can be ignored. However, the SPS PDSCH is also service data, so the terminal device can receive it to ensure a good service experience.

[0273] In Example 10, the first downlink signal includes at least one of the following: a periodic CSI-RS for CSI measurement, an SPS PDSCH, and at least one DCI format carried by a PDCCH in the range of 2_0 to 2_5. The fourth downlink signal does not include: a PDCCH for data scheduling. In this example, the terminal device can perform operations in full accordance with the activation state of the cell DTX in the second time period, that is, the terminal device receives the data transmission PDCCH. Although this consumes more power for the terminal device, the service experience can be guaranteed as much as possible.

[0274] In addition, the above examples 7 to 10 are only examples of commonly used downlink signals. In actual applications, the first downlink signal and the fourth downlink signal may also be other situations, which are not specifically limited here.

[0275] The second case is the scenario where LP-WUS is combined with cell DRX.

[0276] In this case, this step includes: the terminal device does not send the fourth uplink signal in the second time period, or it can be understood that the terminal device determines not to send the fourth uplink signal in the second time period. The second time period does not belong to the first activation time period, but belongs to the third activation time period.

[0277] This situation can also be understood as the priority of the first activation time period being lower than the priority of the third activation time period. It can also be understood as the priority of the LP-WUS being lower than the priority of the cell DRX. It can also be understood as the third time period being the third activation time period excluding the first activation time period. It can also be understood as the first activation time period corresponding to the LP-WUS being inactive, while the third activation time period corresponding to the cell DRX being active.

[0278] Optionally, the terminal device does not send the fourth uplink signal to the network device in the third time period. Correspondingly, the network device does not receive the fourth uplink signal sent by the terminal device in the third time period.

[0279] Example 11, the second uplink signal includes at least one of the following: scheduling request SR, periodic CSI, SPS CSI, periodic SRS, SPS SRS, and unauthorized PUSCH. That is, the cell DRX can act on the second uplink signal. During the inactive time period of the cell DRX, the terminal device does not send and the network device does not receive the second uplink signal accordingly. The fourth uplink signal does not include at least one of the following: scheduling request SR, periodic CSI, SPS CSI, periodic SRS, SPS SRS, and unauthorized PUSCH. In this example, the terminal device can send these fourth uplink signals in the second time period. Considering that these uplink signals are signals that can be acted upon by the cell DRX, and the second time period is an activation time period for the cell DRX. Therefore, the terminal device can send these uplink signals. In this case, for these uplink signals, it is equivalent to that the priority of the cell DRX is higher than the first activation time period corresponding to the LP-WUS.

[0280] Example 12, the second uplink signal includes at least one of the following: a scheduling request SR, periodic CSI, SPS CSI, periodic SRS, SPS SRS, and an unauthorized PUSCH. That is, the cell DRX can act on the second uplink signal. During the inactive time period of the cell DRX, the terminal device does not send, and the network device does not receive, the second uplink signal accordingly. The fourth uplink signal includes at least one of the following: a scheduling request SR, periodic CSI, SPS CSI, periodic sounding reference signal SRS, SPS SRS, and an unauthorized PUSCH. In this example, the second uplink signal and the fourth uplink signal may be the same. The terminal device does not send these fourth uplink signals in the second time period. For these fourth uplink signals, it is equivalent to that the priority of the cell DRX is lower than the first active time period corresponding to the LP-WUS. Since the first active time period is in an inactive state, in order to save energy for the terminal device, the terminal device does not send these fourth uplink signals, even if the cell DRX is in the active time period at this time.

[0281] In Example 13, the second uplink signal includes at least one of the following: a scheduling request (SR), periodic CSI, SPS CSI, periodic SRS, SPS SRS, and grant-free PUSCH. This means that cell DRX can be applied to the second uplink signal. During the cell DRX inactive period, the terminal device does not transmit, and the network device correspondingly does not receive, the second uplink signal. The fourth uplink signal includes at least one of the following: periodic CSI, SPS CSI, periodic sounding reference signal (SRS), and SPS SRS, but does not include at least one of the following: a scheduling request (SR) and grant-free PUSCH. In this example, the terminal device does not transmit at least one of periodic and SPS CSI, or periodic and SPS SRS, during the second time period, but may transmit at least one of SR and grant-free PUSCH. This is because CSI and SRS are auxiliary measurement signals. To maintain low power consumption, the terminal device may not transmit them when no service is guaranteed to arrive. However, SR and grant-free PUSCH indicate that uplink service is arriving, so the terminal device may transmit these uplink signals to ensure a good service experience.

[0282] In addition, the above Examples 11 to 13 are only examples of commonly used uplink signals. In actual applications, the second uplink signal and the fourth uplink signal may also be other situations, which are not specifically limited here.

[0283] It should be noted that the first and second situations described above can exist independently (i.e., a scenario in which LP-WUS is combined with cell DTX, or a scenario in which LP-WUS is combined with cell DRX), or can exist simultaneously (i.e., LP-WUS can exist simultaneously with cell DTX and cell DRX). Specific limitations are not given here.

[0284] In the embodiment of the present application, since the terminal device is already in low-power mode, although the cell is in the DTX activation time period, it may be for the business of other terminal devices. Therefore, from the perspective of saving power consumption, this terminal device does not need to transmit the fourth signal. In other words, if the terminal device has business to be transmitted, the network device can continue to extend the previous first activation time period or use LP-WUS to wake up the first activation time period of the terminal device. Therefore, the benefit of this solution is that the low power consumption of the terminal device is maintained in the second time period.

[0285] Please refer to Figure 10, which is another flow chart of the communication method provided in an embodiment of the present application. The method may include step 1001. Step 1001 can be performed by a terminal device or a network device, or by some components in the terminal device or the network device (such as a processor, a chip or a chip system, etc.), or by a logic module or software that can realize all or part of the functions of the terminal device. The following description is taken as an example of execution by a terminal device or a network device. The processing performed by a single execution subject in step 1001 can also be divided into executions by multiple execution subjects, and these execution subjects can be logically and / or physically separated. For example, the processing performed by the network device can be divided into executions by at least one of the CU, DU and RU. Step 1001 is described in detail below.

[0286] Step 1001: A network device and a terminal device transmit a fifth signal within a third time period.

[0287] The third time period in the embodiment of the present application does not belong to the first activation time period, nor does it belong to the second activation time period, that is, the first activation time period in which LP-WUS is not triggered, nor the second activation time period in which cell DTX is triggered.

[0288] In the embodiment of the present application, the situation in which the network device and the terminal device transmit the fifth signal within the third time period includes at least one of the following: transmitting the fifth uplink signal, transmitting the fifth downlink signal, that is, the terminal device sends the fifth uplink signal to the network device, and the network device sends the fifth downlink signal to the terminal device. Alternatively, it can be understood that the situation in which the network device and the terminal device transmit the fifth signal within the first time period includes at least one of the following: a scenario in which LP-WUS is combined with cell DTX, and a scenario in which LP-WUS is combined with cell DRX. The following are described separately:

[0289] The first case is the scenario where LP-WUS is combined with cell DTX.

[0290] Example 14: The first downlink signal includes at least one of the following: PDCCH for data scheduling, periodic CSI-RS for CSI measurement, SPS PDSCH, and DCI carried by PDCCH with at least one format of 2_0 to 2_5. The fifth signal includes at least one of the following: CSI-RS and PRS for RRM, RLM, TRS, and beam management. In this example, cell DTX cannot act on the first downlink signal, and LP-WUS is mainly for real-time scheduling signals such as data transmission PDCCH, so the terminal device can receive these fifth signals.

[0291] Example 15, the first downlink signal includes at least one of the following: PDCCH for data scheduling, periodic CSI-RS for CSI measurement, SPS PDSCH, and DCI carried by PDCCH with at least one format from 2_0 to 2_5. The fifth signal includes at least one of the following: CSI-RS and PRS for RRM, RLM and beam management; but the fifth signal does not include CSI-RS for TRS. Unlike Example 14, the terminal device can receive these fifth signals, but does not need to receive TRS. Because TRS is mainly for maintaining more frequent time-frequency synchronization for data transmission, considering the power consumption of the terminal device, try not to receive such relatively short-period signals without ensuring that there is business arrival.

[0292] In addition, the above-mentioned Example 14 and Example 15 are only examples of commonly used downlink signals. In actual applications, the first downlink signal and the fifth signal can also be other situations, which are not specifically limited here.

[0293] The second case is the scenario where LP-WUS is combined with cell DRX.

[0294] In Example 16, the second uplink signal includes at least one of the following: a scheduling request (SR), periodic CSI, SPS CSI, periodic SRS, SPS SRS, and ungranted PUSCH. In this example, the cell DRX may act on these second uplink signals, i.e., during the inactive period of the cell DRX, the terminal device does not send, and the network device correspondingly does not receive, these second uplink signals.

[0295] Considering that the second uplink signal cannot be sent during the cell DRX inactive period, the signals that can be sent are basically uplink signals for dynamically scheduled services, such as PUSCH for data transmission, hybrid automatic repeat request acknowledgement (HARQ-ACK), aperiodic CSI and SRS reporting, etc. These dynamically triggered uplink signals are generally sent when the first active period with incoming services is active, and therefore will not appear in the third period.

[0296] In addition, the above example 16 is only an example of a commonly used uplink signal. In actual applications, the second uplink signal can also be other situations, which are not specifically limited here.

[0297] It should be noted that the first and second situations described above can exist independently (i.e., a scenario in which LP-WUS is combined with cell DTX, or a scenario in which LP-WUS is combined with cell DRX), or can exist simultaneously (i.e., LP-WUS can exist simultaneously with cell DTX and cell DRX). Specific limitations are not given here.

[0298] In an embodiment of the present application, the network device can send a fifth signal in a third time period that does not belong to the first activation time and the second activation time period. This removes the restriction issues of cell DTX / DRX and LP-WUS, and can ensure the experience of delay-sensitive services of the terminal device. For example, in the first time period activated by the power consumption wake-up signal, even outside the cell DTX activation time period, the terminal device must at least receive certain downlink signals, such as paging information, within the above-mentioned first time period. In this way, the restriction issue of cell DTX / DRX on the paging information of the activation time period corresponding to the wake-up signal is removed, and the power consumption of the terminal device, the service experience and the power consumption of the network device are taken into account.

[0299] The embodiments shown in Figures 5 to 10 above mainly solve the restriction problem between LP-WUS and cell DTX / DRX in the prior art from the perspective of priority. The following describes how to solve the restriction problem between LP-WUS and cell DTX / DRX in the prior art from the perspective of configuration.

[0300] Please refer to Figure 11, which is a flow chart of a communication method provided in an embodiment of the present application. The method may include steps 1101 and 1102. Steps 1101 and 1102 can be performed by a terminal device or a network device, or by some components in the terminal device or the network device (such as a processor, a chip or a chip system, etc.), or by a logic module or software that can realize all or part of the functions of the terminal device. The following description is taken as an example of execution by a terminal device or a network device. The processing performed by a single execution subject in steps 1101 and 1102 can also be divided into executions by multiple execution subjects, and these execution subjects can be logically and / or physically separated. For example, the processing performed by the network device can be divided into executions by at least one of the CU, DU and RU. Steps 1101 and 1102 are described in detail below.

[0301] Step 1101: The network device sends only one of the first configuration information and the second configuration information to the terminal device.

[0302] The network device sends only one of the first and second configuration information to the terminal device, which can be understood as: if the network device sends the first configuration information to the terminal device, the second configuration information is not sent to the terminal device; and / or, if the network device sends the second configuration information to the terminal device, the first configuration information is not sent to the terminal device. Here, "sending to the terminal device" can also be understood as "determining to send to the terminal device", and / or "not sending to the terminal device" can also be understood as "determining not to send to the terminal device". The first configuration information is used to configure the time domain resources of the first activation time period for the terminal device to receive the low power wake-up signal LP-WUS, and the second configuration information is used to configure the time domain resources of the third activation time period for the cell discontinuous transmission DTX. Alternatively, it can be understood that the terminal device does not expect the LP-WUS and cell DTX configurations to take effect at the same time. Alternatively, it can be understood that the configuration information configured by the network device for the terminal device includes the first configuration information but does not include the second configuration information. Alternatively, the configuration information configured by the network device for the terminal device includes the second configuration information but does not include the first configuration information.

[0303] Specifically, considering that the LP-WUS period is much shorter than that of the cell DTX, once the LP-WUS function is configured and effective, the base station can choose or not to wake up the terminal at any time, so there is no need to configure the cell DTX function.

[0304] The first configuration information and the second configuration information in the embodiments of the present application can refer to the description in the embodiments shown in Figures 5 to 10 above, and will not be repeated here.

[0305] Step 1102: When the first configuration information is sent, the network device sends third configuration information to the terminal device. This step is optional.

[0306] When the first configuration information is sent, the network device sends the third configuration information to the terminal device, which can be understood as: even if the network device sends the first configuration information to the terminal device, the third configuration information can also be sent to the terminal device. Here, "sending the first configuration information to the terminal device" can also be understood as "determining to send the first configuration information to the terminal device", and / or "sending the third configuration information to the terminal device" can also be understood as "determining to send the third configuration information to the terminal device". "When the first configuration information is sent" does not mean that the network device sending the third configuration information to the terminal device depends on the first configuration information being sent, but means that the sending of the first configuration information does not conflict with the sending of the third configuration information.

[0307] In this case, the network device can configure the time domain resources of the first activation time period and the time domain resources of the third activation time period for the terminal device, that is, the LP-WUS and the cell DRX can be configured and take effect at the same time. Alternatively, it can be understood that the terminal device does not expect the LP-WUS and the cell DTX to be configured and take effect at the same time, but can expect the LP-WUS and the cell DRX to be configured and take effect at the same time.

[0308] The combination of LP-WUS and cell DRX in the embodiment of the present application can refer to the description of the embodiments shown in Figures 5 to 10 above, and will not be repeated here.

[0309] It is understood that if step 1102 is present, there may be no timing restriction between step 1101 and step 1102. For example, the network device may first send the third configuration information and then send the first configuration information. For another example, the network device may first send the first configuration information and then send the third configuration information. For another example, the network device may send the first configuration information and the third configuration information simultaneously.

[0310] In an embodiment of the present application, the network device may configure time domain resources for the terminal device only during the first activation period, or only during the third activation period, thereby reducing the conflict between LP-WUS and cell DTX. Alternatively, the network device may avoid the introduction of complex coexistence rules by not simultaneously activating LP-WUS and cell DTX. For example, the network device may balance network device power consumption and service experience by selecting or not waking up the terminal device, with terminal device power consumption primarily guaranteed by the low power mode of LP-WUS.

[0311] To the extent that the technical solutions in the embodiments of the present application do not conflict with each other, the various embodiments may be combined with each other. For example, in the embodiment shown in FIG11 , when LP-WUS and cell DRX are configured and effective simultaneously, at least one of the following steps may also be included: the network device sends an LP-WUS to the terminal device, the network device and the terminal device transmit a third signal within a first time period, the network device and the terminal device do not transmit a fourth signal within a second time period, and the network device and the terminal device transmit a fifth signal within a third time period. For details, please refer to the description of the embodiments shown in FIG5 to FIG10 above, and no further details will be given here.

Please refer to Figure 12.

[0349] In this embodiment, in a scenario where LP-WUS is combined with DTX / DRX, the terminal device can transmit a third signal during the first activation period activated by the low-power wake-up signal, even outside the activation period of the cell DTX or cell DRX. Alternatively, this can be understood as removing the restriction of cell DTX / DRX on signal transmission during the first activation period corresponding to the wake-up signal, thus balancing terminal device power consumption, service experience, and network device power consumption.
