[0092] FIG. 1 is a schematic diagram of an architecture of a communication system according to an embodiment of the present disclosure.

[0093] As shown in FIG. 1, the communication system 100 includes a terminal 101 and a network device 102. The network device 102 can include an access network device and / or a core network device. The terminal can also be referred to as a UE.

[0095] In some embodiments, the UE is also referred to as a User Equipment (UE).

[0096] In some embodiments, the access network device may, for example, be at least one of a node or a device that accesses a UE to a wireless network, and the access network device may, for example, include at least one of an evolved NodeB (eNB) in a 5G communication system, a next generation eNB (ng-eNB), a next generation NodeB (gNB), a node B (NB), a home node B (HNB), a home evolved node B (HeNB), a wireless backhaul device, a radio network controller (RNC), a base station controller (BSC), a base transceiver station (BTS), a base band unit (BBU), a mobile switching center, a base station in a 6G communication system, an Open RAN, a Cloud RAN, a base station in other communication systems, an access node in a Wi-Fi system, but is not limited thereto.

[0097] In some embodiments, the technical means of the present disclosure can be applicable to an Open RAN architecture, at which time the interfaces between or within the access network devices involved in the embodiments of the present disclosure can become internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0098] In some embodiments, the access network device can be composed of a central unit (CU) and a distributed unit (DU), where the CU can also be referred to as a control unit. The CU-DU structure can split the protocol layers of the access network device, and some of the protocol layers can be controlled by the CU, and the rest or all of the protocol layers can be distributed in the DU and controlled by the CU, but is not limited thereto.

[0099] In some embodiments, the core network device can be one device including the first network element, or can be multiple devices or device groups each including the first network element. The network element can be virtual or physical. The core network may, for example, include at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next generation core (NGC).

[0100] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical means of the embodiments of the present disclosure, and does not constitute a limitation on the technical means provided by the embodiments of the present disclosure. It can be known by those skilled in the art that, as the system architecture evolves and new service scenarios appear, the technical means provided by the embodiments of the present disclosure are also applicable to similar technical problems.

[0101] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1 or part of the subject, but are not limited thereto. The subjects shown in FIG. 1 are exemplary, and the communication system can include all or part of the subjects in FIG. 1, or other subjects other than FIG. 1. The number and form of each subject is arbitrary, and the connection relationship between the subjects is exemplary. The subjects can be connected or not connected, and the connection can be in any way, can be direct connection or indirect connection, can be wired connection or wireless connection.

[0102] Embodiments of the present disclosure can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 5G new radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (Bluetooth (registered trademark)), Public Land Mobile Network (PLMN) network, device-to-device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other resources, next-generation system extended based thereon, and the like. Further, a plurality of systems can be combined (for example, LTE and NR can be combined).

[0103] In a low power wake up signal (LP WUS) research project, a base station sends a low power wake up signal to a UE to wake up the UE. The UE can keep a main radio (MR) asleep, use a separate low power wake radio (LR) to receive the LP WUS, and after receiving the LP WUS, wake up the main receiver of the UE for data transmission and reception operations, and the like, that is, the MR is woken up from a sleep state to an active state.

[0104] The main radio of the UE can have different degrees of sleep states, for example, can be divided into deep sleep, light sleep, and micro sleep. The energy consumption levels of different degrees of sleep states are different, and the state transition time (also called wake-up delay) required from the sleep state to the normal working state is also different. The deeper the sleep degree, the lower the energy consumption level and the more energy-saving, but the longer the corresponding wake-up delay. For example, the wake-up time of deep sleep is 10 ms, the wake-up time of light sleep is 3 ms, and the wake-up time of micro sleep can be considered as 0 ms.

[0105] If the UE service is very sparse, for example, a service packet arrives every few hundred milliseconds, it is suitable to use deeper sleep, and if the service arrives very densely, it is suitable to use very shallow sleep or even no sleep.

[0106] In a new radio (NR) system, a terminal can be configured and activated with some semi-persistent channels, for example, SPS PDSCH, CG PUSCH, SP CSI report sent on PUCCH, SP CSI report sent on PUCCH, and the like. These channels are required to be periodically received and transmitted by the terminal.

[0107] In some embodiments, if the UE has been configured or activated with a semi-persistent channel, the UE needs to be in an active state at least during the transmission and reception period of the semi-persistent channel. If the UE receives the LP WUS within the time range of the semi-persistent channel, no wake-up delay is required or the original longer wake-up delay is not required. How to determine the wake-up delay size of the LP WUS to wake up the UE in the case where the UE is configured or activated with a semi-persistent channel?

[0108] As shown in FIG. 2A, the embodiment of the disclosure provides a communication method, which is executed by the communication system shown in FIG. 1. The method can include:

[0109] S2101: A network device sends a first signal to a UE.

[0110] In some embodiments, the network device can be an access network device, e.g., various types of base stations.

[0111] In some embodiments, the UE can be various types of terminals, e.g., a mobile phone, a tablet computer, a vehicle-mounted device, or a flight device, etc.

[0112] In some embodiments, the first signal can be the aforementioned LP WUS. Illustratively, the first signal is used to wake up the second receiver of the UE to monitor the PDCCH. Illustratively, when the network device needs to schedule or trigger the UE to perform downlink reception and / or uplink transmission through the DCI sent by the PDCCH, the network device can make the UE monitor the PDCCH through the sending of the first signal, and obtain the scheduling information of the network device based on the monitoring of the PDCCH.

[0113] In some embodiments, the network device sends the first signal to the UE in the sleep state.

[0114] In some embodiments, the network device sends the first signal at the sending occasion of the first signal according to the configuration information of the first signal. Illustratively, the configuration information of the first signal can periodically configure the sending occasion of the first signal. The network device can send the first signal at the sending occasion of the first signal, or can not send the first signal.

[0115] Correspondingly, the UE uses the first receiver to monitor the first signal. In some embodiments, the first signal can be the LP WUS received by the first receiver of the UE. Illustratively, the power consumption of the first receiver is less than that of the second receiver. Illustratively, the receiving capability of the first receiver is weaker than that of the second receiver. In some embodiments, the first receiver has receiving capability but does not have transmitting capability. The second receiver has receiving capability and has transmitting capability. In some embodiments, the second receiver can be an MR.

[0116] In some embodiments, the first receiver can monitor the first signal, but cannot monitor the PDCCH, so when the UE needs to monitor the PDCCH, the sending of the first signal is needed to wake up the second receiver of the UE to monitor the PDCCH.

[0117] S2102: The network device and / or the UE determines the wake-up delay.

[0118] In some embodiments, the UE determines the wake-up delay according to the relationship between the end moment of the reception of the first signal and the time domain position of the semi-persistent channel.

[0119] In an embodiment, the wake-up delay is the delay of waking up the second receiver to monitor the physical downlink control channel (PDCCH).

[0120] In some embodiments, Half-Duplex Channel Access generally refers to a channel access method used by user equipment (UE) when communicating in a half-duplex mode in a wireless communication system. In this mode, the device can transmit or receive in different time periods, but cannot transmit and receive simultaneously.

[0121] When a UE communicates based on a half-duplex channel, it has the following characteristics:

[0122] UE in half-duplex communication: In half-duplex mode, the UE cannot transmit and receive simultaneously, which means it must separately transmit and receive data in different time intervals.

[0123] Slot operation: Half-duplex scheduling is usually performed in specific time slots, which can be pre-allocated or dynamically scheduled.

[0124] Power control: To improve communication quality, the UE may perform power control according to channel conditions and network instructions.

[0125] Conflict avoidance: Due to the inability to transmit and receive simultaneously, the UE needs to take measures to avoid potential channel conflicts.

[0126] Channel sensing: The UE may need to periodically sense the channel state to determine the best transmission opportunity.

[0127] Timer management: The UE may use timers to manage channel access attempts, such as waiting for the base station's response after sending a channel request.

[0128] Adaptability: Half-duplex channel access can adapt to different network conditions and communication needs by adjusting transmission power, time slot length, and access strategy to optimize performance.

[0129] Channel utilization: By dynamically requesting and allocating channel resources, channel utilization can be improved.

[0130] Delay and reliability: Half-duplex channel access may trade off between delay and reliability according to the needs of the application.

[0131] Energy saving: For applications that do not require continuous communication, half-duplex channel access can reduce the energy consumption of the device.

[0132] It can be seen that when the UE transmits on the half-duplex channel, although the second receiver is in an awake state, only uplink or downlink transmission is supported, or only specific channel transmission is supported. That is, the UE does not listen to the PDCCH.

[0133] In some embodiments, the semi-persistent channel can include a traffic channel and / or an uplink control channel. The second receiver of the UE is in a wake-up state to monitor the semi-persistent channel, but the second receiver of the UE is only in a state to monitor the semi-persistent channel and does not monitor the PDCCH. Therefore, the network device needs to wake up the second receiver of the UE to monitor the PDCCH through the first signal.

[0134] Exemplarily, the semi-persistent channel can include, but is not limited to, at least one of the following:

[0135] Semi-persistent scheduling physical downlink shared channel (SPS PDSCH);

[0136] Configured grant physical uplink shared channel (CG PUSCH);

[0137] Physical uplink shared channel (PUSCH) for reporting semi-persistent channel state information (CSI) reporting;

[0138] Physical uplink control channel (PUCCH) for reporting semi-persistent channel state information (CSI) reporting.

[0139] In some embodiments, the SPS PDSCH is a PDSCH of SPS, and the UE can send various traffic data on the SPS PDSCH. Semi-persistent scheduling is a resource allocation mechanism that allows the network to pre-allocate resources to user equipment (UE) for periodic data transmission. This scheduling reduces the channel request messages on the control channel, thereby saving wireless resources and reducing latency. SPS is usually used for services that have periodic data transmission needs, such as real-time video streaming or periodic data updates.

[0140] In some embodiments, the CG PUSCH can be a PUSCH scheduled by CG. Exemplarily, in the authorization process of the CG PUSCH, the base station allocates specific PUSCCH resources to the UE according to the needs of the UE and the resource status of the network. This authorization includes resource location, transmission power, modulation and coding scheme (MCS), and other related parameters.

[0141] In some embodiments, the CSI report can include feedback information of measuring the CSI-RS. The semi-persistent channel can include PUSCH and / or PUCCH for transmitting the CSI report.

[0142] The optional mode of S2102 includes multiple modes, and several optional embodiments are provided as follows:

[0143] Optional mode one:

[0144] The receiving end moment of the first signal overlaps with the time domain of the semi-persistent channel, and the wake-up delay is determined as 0.

[0145] If the network device configures the semi-persistent channel for the second receiver, the UE needs to listen to the semi-persistent channel through the second receiver, which indicates that the second receiver of the UE is in a wake-up state, and the time required for switching to the wake-up state for listening to the PDCCH can be considered as 0, that is, the wake-up delay is 0.

[0146] As shown in FIG. 2B, the first signal is transmitted for a period of time, and the UE receives the first signal for a period of time. The transmission period of the first signal at least partially overlaps with the time domain position of the first semi-persistent channel, and the wake-up delay can be considered as 0. In FIG. 2B, Tx is one kind of illustration of the receiving end moment of the first signal.

[0147] In some embodiments, the receiving end moment of the first signal overlaps with the time domain position of the first semi-persistent channel, and the receiving end moment of the first signal is earlier than the end moment of the first semi-persistent channel, and the wake-up delay can be determined as 0.

[0148] In another embodiment, the receiving end moment of the first signal is located in the range of the time domain position of the first semi-persistent channel, and the wake-up delay can be considered as 0.

[0149] Optionally, the second way is:

[0150] According to the relative position relationship, the wake-up delay is determined.

[0151] In some embodiments, the first time domain range is determined according to the time domain position of the semi-persistent channel. Exemplarily, the first time domain position includes at least one time domain position of the semi-persistent channel adjacent to the receiving end moment of the first signal.

[0152] In some embodiments, the first time domain range is from the first time to the second time; the first time is earlier than the start moment of the first semi-persistent channel, and the first time is determined by the start moment of the first semi-persistent channel and the first time length.

[0153] In another embodiment, the second time is later than the end moment of the first semi-persistent channel, and the second time is determined by the end moment of the first semi-persistent channel and the second time length; the first semi-persistent channel is the semi-persistent channel closest to the receiving end moment of the first signal.

[0154] In some embodiments, the first time length and / or the second time length can be determined by a protocol, a network device, or the UE itself.

[0155] In some embodiments, the first time duration and the second time duration are related to the capability of the UE to wake up the second receiver to monitor the PDCCH, the progress of the preparation of turning on the second receiver based on the start of the semi-persistent channel, and the progress of the preparation of turning off the second receiver based on the end of the semi-persistent channel.

[0156] In some embodiments, the first time duration and the second time duration are configured by the network device, or are agreed by the protocol.

[0157] In some other embodiments, the first time duration and / or the second time duration are related to the capability of the UE to wake up the second receiver. For example, the stronger the capability of the UE to wake up the second receiver, the shorter the time required for the UE to wake up the second receiver, and the later the UE can start the wake-up operation of waking up the second receiver based on the transmission of the semi-persistent channel. The stronger the capability of the UE to wake up the second receiver, the shorter the time required for the UE to turn off the second receiver. In this case, the length of the first time duration and / or the second time duration is inversely related to the capability of the UE to wake up the second receiver.

[0158] In some embodiments, the end time of the reception of the first signal is within the first time duration, and the wake-up delay is determined to be 0.

[0159] In some embodiments, the end time of the reception of the first signal is within the first time duration, and the wake-up delay is determined to be the first delay, which is related to the demodulation time of the first signal. For example, the first delay can be 0 or not. For example, the UE receives the first signal and demodulates the first signal, if the demodulation capability of the UE is strong, the first delay is 0, otherwise the first delay is greater than 0.

[0160] In some embodiments, the end time of the reception of the first signal is within the first time duration, and the wake-up delay is determined to be the second delay, which is less than the third delay, and the third delay is the time delay of waking up the second receiver to monitor the PDCCH.

[0161] In some embodiments, the end time of the reception of the first signal is within the first time duration, and the wake-up delay is determined to be the sum of the first delay and the second delay.

[0162] In some embodiments, the end time of the reception of the first signal is within the first time duration and is earlier than or equal to the start time of the first semi-persistent channel, and the wake-up delay is determined according to the third delay, the end time of the reception, and the start time of the first semi-persistent channel.

[0163] In some embodiments, the reception end moment of the first signal is located in the first time domain range and the reception end moment of the first signal is later than the end moment of the first semi-persistent channel, and the wake-up delay is determined according to the third delay, the reception end moment and the end moment of the first semi-persistent channel.

[0164] In some embodiments, the reception end moment of the first signal is located in the first time domain range and the reception end moment of the first signal is earlier than or equal to the start moment of the first semi-persistent channel, and the wake-up delay is determined according to the first delay, the third delay, the reception end moment and the start moment of the first semi-persistent channel.

[0165] In some embodiments, the reception end moment of the first signal is located in the first time domain range and the reception end moment of the first signal is later than the end moment of the first semi-persistent channel, and the wake-up delay is determined according to the first delay, the third delay, the reception end moment and the end moment of the first semi-persistent channel.

[0166] In some embodiments, the reception end moment of the first signal is located outside the first time domain range, and the wake-up delay is determined as the third delay.

[0167] In some embodiments, the first time domain range can be as shown in FIGS. 2C-2F.

[0168] Considering the time domain position of the semi-persistent channel, the UE needs to wake up the second receiver for uplink transmission and / or downlink reception of the semi-persistent channel, and meanwhile, before the start of the semi-persistent channel, the UE performs the relevant operation of waking up the second receiver, and after the end of the semi-persistent channel, the UE performs the relevant operation of closing the second receiver, so that in the time domain position of the semi-persistent channel, the wake-up delay of the second receiver for listening to the PDCCH can be close to 0, and before the start of the semi-persistent channel, because the UE has already prepared the work of waking up the second receiver for the semi-persistent channel, so in this case, the first signal is received, which can reduce the delay required by the UE to wake up the second receiver for listening to the PDCCH. In a period of time after the end of the semi-persistent channel, the UE performs the relevant operation of closing the second receiver, but the relevant operation is also gradually performed, and at this time, the UE receives the first signal, and because the second receiver is not completely closed, the wake-up delay is also shorter than that in the case without the semi-persistent channel. Therefore, in the embodiments of the present disclosure, the wake-up delay is determined according to the relative positional relationship between the reception end moment of the first signal and the first time domain range.

[0169] In one case, if the reception end moment of the first signal overlaps with the first time domain range, the wake-up delay is directly determined as 0. Exemplarily, as shown in FIG. 2C, the reception end moment of the first signal (Tx) overlaps with the start moment of the semi-persistent channel, and the wake-up delay is directly determined as 0.

[0170] In some embodiments, considering that information demodulation is needed after the first signal is received, in the embodiments of the present disclosure, in order to further accurately determine the wake-up delay, the first delay is considered. In some embodiments, the first delay is related to the demodulation time of the first signal. Exemplarily, the first delay can be defined as the demodulation delay of the first signal. Further exemplarily, the first delay can be the time difference between the end time of the reception of the first signal and the completion time of demodulating the first signal.

[0171] In some embodiments, the first delay is the time difference between the end time of the reception of the first signal and the demodulation of the first signal by the UE.

[0172] In some embodiments, the first delay can be determined by a protocol, a network device or the UE itself. For example, the protocol can uniformly define the first delay of the demodulation of the first signal according to the complexity of the first signal, the MCS of the protocol and the like. Further for example, the protocol can also define different first delays for different types of UEs and / or UE capabilities. Generally, the stronger the demodulation capability of the UE, the smaller the first delay. In some embodiments, the UE can determine the first delay according to its own capability and / or historical data of demodulating the first signal.

[0173] In some embodiments, the end time of the reception of the first signal is within the first time domain range, and the wake-up delay is determined as the second delay.

[0174] In some embodiments, the second delay is smaller than the third delay. In some embodiments, the third delay can be the delay of the UE waking up the second receiver when the end time of the reception of the first signal is outside the first time domain range or when there is no semi-persistent channel. Exemplarily, the third delay is the delay of waking up the second receiver to listen to the PDCCH.

[0175] In some embodiments, the third delay can be determined by a protocol, a network device or the UE itself. For example, the protocol can uniformly define the third delay, or define the third delay according to the UE type or UE capability. The network device can uniformly configure the third delay or distinguish the third delay according to the MCS of the first signal sent by the network device, the information length carried by the first signal, the decoding complexity and the like. In some other embodiments, the UE can determine the third delay according to its own historical statistical data of waking up the second receiver to listen to the PDCCH based on the first signal.

[0176] In some embodiments, the time difference between the second delay and the third delay can be determined by a protocol or calculation. For example, the protocol can predefine that the second delay and the third delay have a predetermined proportional relationship, and the time difference between the second delay and the third delay can be calculated by the UE itself.

[0177] In some embodiments, the second time delay can also be a specified value or an alternative value agreed by a protocol or configured by a network device.

[0178] Since the end time of the reception of the first signal is located in the first time domain range, the wake-up time delay is shortened, so that the wake-up time delay is the second time delay rather than the third time delay.

[0179] In some embodiments, the end time of the reception of the first signal is located in the first time domain range, and the end time of the reception of the first signal is earlier than or equal to the start time of the first semi-persistent channel. The wake-up time delay is determined according to the third time delay, the end time of the reception of the first signal, and the start time of the first semi-persistent channel. In other embodiments, the end time of the reception of the first signal is located in the first time domain range, and the end time of the reception of the first signal is earlier than or equal to the start time of the first semi-persistent channel. The wake-up time delay is determined according to the first time delay, the third time delay, the end time of the reception of the first signal, and the start time of the first semi-persistent channel.

[0180] In this embodiment, the time required for demodulation of the first signal is considered, and the influence of the semi-persistent channel on the wake-up of the second receiver to listen to the PDCCH is also considered. The wake-up time delay is determined as the sum of the first time delay and the second time delay.

[0181] In some embodiments, the end time of the reception of the first signal is located in the first time domain range and the end time of the reception of the first signal is earlier than or equal to the start time of the first semi-persistent channel. The wake-up time delay is determined according to the third time delay, the end time of the reception of the first signal, and the start time of the first semi-persistent channel. In other embodiments, the end time of the reception of the first signal is located in the first time domain range and the end time of the reception of the first signal is earlier than or equal to the start time of the first semi-persistent channel. The wake-up time delay is determined according to the first time delay, the third time delay, the end time of the reception of the first signal, and the start time of the first semi-persistent channel.

[0182] In the two embodiments, since the reception time of the first signal is earlier than the start time of the first semi-persistent channel, the influence of the preparation work of the UE based on the start of the first semi-persistent channel on the wake-up of the second receiver is mainly considered, and the wake-up time delay is determined in combination with the first time delay and / or the third time delay, so as to distinguish the influence of the wake-up preparation work of the second receiver and the closing work of the second receiver on the wake-up time delay of the second receiver to listen to the PDCCH, and the accuracy of the wake-up time delay is improved. Exemplarily, the time domain position relationship between the end time of the reception of the first signal and the semi-persistent channel can be as shown in FIG. 2C and FIG. 2E. The end time of the reception of the first signal (Tx) shown in FIG. 2C is equal to the start time of the first semi-persistent channel. In this case, the wake-up time delay can be determined according to the third time delay, the end time of the reception of the first signal, and the start time of the first semi-persistent channel, or the wake-up time delay can be determined according to the first time delay, the third time delay, the end time of the reception of the first signal, and the start time of the first semi-persistent channel. The end time of the reception of the first signal (Tx) shown in FIG. 2E is earlier than the start time of the first semi-persistent channel. In this case, the wake-up time delay can be determined according to the third time delay, the end time of the reception of the first signal, and the start time of the first semi-persistent channel, or the wake-up time delay can be determined according to the first time delay, the third time delay, the end time of the reception of the first signal, and the start time of the first semi-persistent channel.

[0183] In some embodiments, the wake-up delay is determined according to the third delay, the end time of the reception, and the start time of the first semi-persistent channel, including: determining the wake-up delay as the smaller one between the third delay and a first interval, where the first interval is a time interval between the end time of the reception and the start time of the first semi-persistent channel. In this way, it is equivalent to considering the wake-up delay as the smaller one between the third delay and the first interval, so as to accelerate the transmission of the DCI on the PDCCH as much as possible.

[0184] In other embodiments, the wake-up delay is determined according to the third delay, the end time of the reception, and the start time of the first semi-persistent channel, including:

[0185] determining the wake-up delay as the larger one between the third delay and a first interval, where the first interval is a time interval between the end time of the reception and the start time of the first semi-persistent channel. In this case, the network device can ensure the transmission success rate of the DCI and reduce the DCI reception failure of the UE by transmitting the DCI on the PDCCH according to the wake-up delay.

[0186] In some embodiments, the wake-up delay is determined according to the first delay, the third delay, the end time of the reception, and the start time of the first semi-persistent channel, including: determining the wake-up delay as the smaller one between the third delay and a third duration, where the third duration is a sum of the first interval and the first delay; and the first interval is a time interval between the end time of the reception and the start time of the first semi-persistent channel. In this way, it is equivalent to considering the wake-up delay as the smaller one between the third delay and the third duration, so as to accelerate the transmission of the DCI on the PDCCH as much as possible.

[0187] In some embodiments, the wake-up delay is determined according to the first delay, the third delay, the end time of the reception, and the start time of the first semi-persistent channel, including: determining the wake-up delay as the larger one between the third delay and a third duration, where the third duration is a sum of the first interval and the first delay; and the first interval is a time interval between the end time of the reception and the start time of the first semi-persistent channel. In this way, the network device can ensure the transmission success rate of the DCI and reduce the DCI reception failure of the UE by transmitting the DCI on the PDCCH according to the wake-up delay.

[0188] In some embodiments, the receiving end time of the first signal is located in the first time domain range and is later than the end time of the first semi-persistent channel, and the wake-up delay is determined according to the third delay, the receiving end time and the end time of the first semi-persistent channel. In other embodiments, the receiving end time of the first signal is located in the first time domain range and is later than the end time of the first semi-persistent channel, and the wake-up delay is determined according to the first delay, the third delay, the receiving end time and the end time of the first semi-persistent channel.

[0189] In these two embodiments, considering that the receiving time of the first signal is later than the end time of the first semi-persistent channel, the influence of gradually turning off the second receiver after the end of the first semi-persistent channel is mainly considered, and the wake-up delay is determined in combination with the first delay and / or the third delay, so as to accurately determine the delay of waking up the second receiver to listen to the PDCCH. Exemplarily, the time domain position relationship between the receiving end time of the first signal and the semi-persistent channel can be as shown in FIG. 2D and FIG. 2F. FIG. 2D shows that the receiving end time of the first signal is equal to the end time of the first semi-persistent channel. FIG. 2F shows that the receiving end time of the first signal is later than the end time of the first semi-persistent channel.

[0190] In some embodiments, the wake-up delay is determined according to the third delay, the receiving end time and the end time of the first semi-persistent channel, including: determining the wake-up delay as the smaller one between the third delay and a second interval, where the second interval is the time interval between the receiving end time and the end time of the first semi-persistent channel. In this way, it is equivalent to considering that the wake-up delay is the smaller one between the third delay and the second interval, so as to accelerate the transmission of DCI on the PDCCH as much as possible.

[0191] In some embodiments, the wake-up delay is determined according to the third delay, the receiving end time and the end time of the first semi-persistent channel, including: determining the wake-up delay as the smaller one between the third delay and a second interval, where the second interval is the time interval between the receiving end time and the end time of the first semi-persistent channel. In this case, the network device can ensure the transmission success rate of DCI by sending DCI on the PDCCH according to the wake-up delay, and reduce the DCI receiving failure of the UE.

[0192] In some embodiments, the wake-up delay is determined according to the first delay, the third delay, the receiving end time and the end time of the first semi-persistent channel, including: determining the wake-up delay as the smaller one between the third delay and a fourth time length, and the fourth time length is the sum of the second interval and the first delay; the second interval is the time interval between the receiving end time and the end time of the first semi-persistent channel. In this way, it is equivalent to considering that the wake-up delay is the smaller one between the third delay and the second interval, so as to accelerate the transmission of DCI on the PDCCH as much as possible.

[0193] In some embodiments, the first signal comprises one or more wake-up information, and the method further comprises determining the reception end time of the first signal as at least one of: a time at which the UE receives all the wake-up information in the first signal; and a time at which the UE receives the wake-up information for the UE in the first signal.

[0194] In some embodiments, the first signal comprises one or more wake-up information, and the method further comprises determining the reception end time of the first signal as at least one of: a time at which the UE receives all the wake-up information in the first signal; and a time at which the UE receives the wake-up information for the UE in the first signal.

[0195] In some embodiments, the first signal comprises one or more wake-up information, and the method further comprises determining the reception end time of the first signal as at least one of: a time at which the UE receives all the wake-up information in the first signal; and a time at which the UE receives the wake-up information for the UE in the first signal.

[0196] In some embodiments, the first signal comprises one or more wake-up information, and the method further comprises determining the reception end time of the first signal as at least one of: a time at which the UE receives all the wake-up information in the first signal; and a time at which the UE receives the wake-up information for the UE in the first signal.

[0197] In some embodiments, the first signal comprises one or more wake-up information, and the method further comprises determining the reception end time of the first signal as at least one of: a time at which the UE receives all the wake-up information in the first signal; and a time at which the UE receives the wake-up information for the UE in the first signal.

[0198] In some embodiments, the UE and the network device can not determine the wake-up latency at the same time. Illustratively, the UE determines the wake-up latency, informs the network device of the wake-up latency through an uplink message after determining the wake-up latency, and the network device obtains the wake-up latency of the UE based on the uplink message of the UE. Alternatively, the UE does not determine the wake-up latency, and the network device determines the wake-up latency, and the wake-up latency of the UE depends on the wake-up of the specific second receiver. The network device can send the DCI to the UE after determining the wake-up latency, and the UE completely wakes up the second receiver to listen to the PDCCH. That is, the UE determining the wake-up latency or the network device determining the wake-up latency can be optional steps.

[0199] In some embodiments, the term "information" can be mutually replaced with the terms "message", "signal", "signaling", "report", "configuration", "indication", "instruction", "command", "channel", "parameter", "field", "data", and the like.

[0203] S3101: receiving a first signal.

[0204] In some embodiments, the UE receives the first signal sent by the network device.

[0205] In some embodiments, the UE, the network device, the first signal, and the like are described in the corresponding embodiments of FIG. 2A, which will not be repeated here.

[0206] S3102: confirming a wake-up latency.

[0207] In some embodiments, the UE determines the wake-up delay according to a relationship between a reception end moment of the first signal and a time domain position of the semi-persistent channel.

[0208] In some embodiments, the wake-up delay is a delay of waking up the second receiver to monitor a physical downlink control channel (PDCCH).

[0209] In some embodiments, the manner in which the UE determines the wake-up delay can refer to any one of the optional implementation manners of S2102 of the corresponding embodiment of FIG. 2A, which will not be repeated here.

[0210] In some embodiments, the UE does not determine the wake-up delay, but the network device determines the wake-up delay, and the wake-up delay of the UE depends on the wake-up of the specific second receiver. After determining the wake-up delay, the network device can send a DCI to the UE after the UE completely wakes up the second receiver to monitor the PDCCH. That is, whether the UE determines the wake-up delay or the network device determines the wake-up delay can be an optional step. That is, in some cases, S3102 is an optional step.

[0211] As shown in FIG. 4, the embodiment of the present disclosure provides a communication method, wherein the method is performed by a network device. The method can include:

[0212] S4101: sending a first signal.

[0213] In some embodiments, the network device sends the first signal to the UE.

[0214] In some embodiments, the UE, the network device, the first signal, and the like can refer to the corresponding embodiments of FIG. 2A, which will not be repeated here.

[0215] S4102: confirming a wake-up delay.

[0216] In some embodiments, the network device determines the wake-up delay according to a relationship between a reception end moment of the first signal and a time domain position of the semi-persistent channel.

[0217] In some embodiments, the wake-up delay is a delay of waking up the second receiver to monitor a physical downlink control channel (PDCCH).

[0218] In some embodiments, the manner in which the network device determines the wake-up delay can refer to any one of the optional implementation manners of S2102 of the corresponding embodiment of FIG. 2A, which will not be repeated here.

[0219] In some embodiments, the network device determining the wake-up delay is an optional step. For example, the UE determines the wake-up delay, and after determining the wake-up delay, the UE informs the network device through an uplink message, and the network device obtains the wake-up delay of the UE based on the uplink message of the UE.

[0220] In the embodiments of the present disclosure, part or all of the steps, and optional implementation manners thereof, can be combined with part or all of the steps in other embodiments, or combined with optional implementation manners of other embodiments.

[0221] In the embodiments of the present disclosure, part or all of the steps, and optional implementation manners thereof, can be combined with part or all of the steps in other embodiments, or combined with optional implementation manners of other embodiments.

[0222] The embodiments of the present disclosure propose a method for determining the wake-up latency of a UE woken up by an LP WUS in a scenario where the UE is configured or activated with a semi-persistent channel.

[0223] In some embodiments, the length of the wake-up latency is determined by the relationship between the reception time of the LP WUS and the time domain position of the semi-persistent channel after the UE receives the LP WUS.

[0224] Embodiment 1:

[0225] If the reception time of the LP WUS overlaps with the time domain position of the semi-persistent channel, as shown in FIG. 2B, the wake-up latency of the UE woken up by the LP WUS is considered to be 0. That is, it is considered that the UE has been woken up within the time domain position of the semi-persistent channel, and can perform normal data transmission and reception.

[0226] The semi-persistent channel is an SPS PDSCH, a CG PUSCH, an SPS CSI report on a PUSCH, and / or an SPS CSI report sent on a PUCCH, etc.

[0227] The reception time of the LP WUS can be the end time of the LP WUS. If the UE does not need to receive the entire LP WUS signal, but only needs to receive part of the LP WUS signal to demodulate the wake-up information corresponding to itself. For example, the LP WUS signal starts at t0 and ends at t1, the wake-up information corresponding to UE1 is located at t0-t1UE1, and t1UE1<t1, then the reception time of the LP WUS refers to the end time of the information corresponding to the UE in the LP WUS signal, that is, the time of t1UE1 in the above example.

[0228] For example, the UE will wake up at the next time domain unit (e.g., the next symbol, the next slot) of the reception time of the LP WUS and enter a normal working state.

[0229] Embodiment 2:

[0230] If the reception time of the LP WUS overlaps with the time-domain location of the semi-persistent channel, as shown in FIG. 2C, the wake-up latency of the UE woken up by the LP WUS is considered to be Tprocess, where Tprocess is the time length for the UE to demodulate the LP WUS information after receiving the LP WUS signal. That is, the UE can be woken up after the UE completes the demodulation of the LP WUS information. Exemplarily, the Tprocess can be one of the first latency mentioned above.

[0231] The semi-persistent channel is an SPS PDSCH, a CG PUSCH, an SP CSI report sent on a PUSCH, an SP CSI report sent on a PUCCH, and the like.

[0232] The reception time of the LP WUS can be the end time of the LP WUS. If the UE does not need to receive the entire LP WUS signal, but only needs to receive part of the LP WUS signal to demodulate the wake-up information corresponding to itself, the reception time of the LP WUS refers to the end time of the information corresponding to the UE in the LP WUS signal.

[0233] For example, the UE will wake up at the next time domain unit (for example, the next symbol, the next slot) after Tprocess time after the reception time of the LP WUS, and enter a normal working state.

[0234] In some embodiments, if the reception time of the LP WUS is in the first time domain range, as shown in FIGS. 2B to 2F, the wake-up latency of the UE woken up by the LP WUS is considered to be 0. That is, it is considered that the UE is in an active state and can normally perform data transmission and reception in the first time domain range.

[0235] In some embodiments, the semi-persistent channel is an SPS PDSCH, a CG PUSCH, an SP CSI report sent on a PUSCH, an SP CSI report sent on a PUCCH, and the like.

[0236] In some embodiments, the reception time of the LP WUS can be the end time of the LP WUS. If the UE does not need to receive the entire LP WUS signal, but only needs to receive part of the LP WUS signal to demodulate the wake-up information corresponding to itself. For example, the LP WUS signal starts at t0 time and ends at t1 time, the wake-up information corresponding to UE1 is located at t0-t1 UE1, and t1 UE1 < t1, the reception time of the LP WUS refers to the end time of the information corresponding to the UE in the LP WUS signal, that is, the time of t1 UE1 in the above example.

[0237] In some embodiments, the first time domain range comprises a T1 moment before the beginning of the semi-persistent channel to the beginning moment of the semi-persistent channel, and / or the end moment of the semi-persistent channel to a T2 moment after the end moment.

[0238] In some embodiments, T1 and T2 can be the same or different.

[0239] The wake-up indication T1 / T2 is configured by the network or defined by the protocol. T1 / T2 can be related to the UE wake-up capability.

[0240] The UE can report the UE capability related to the T1 / T2. In theory, when the UE wake-up capability is strong, the T1 / T2 time will be shorter.

[0241] A special case is T1 = 0, that is, the reception moment of the LP WUS is the same as the beginning moment of the semi-persistent channel. Another special case is T2 = 0, that is, the reception moment of the LP WUS is the same as the end moment of the semi-persistent channel.

[0242] Embodiment 3:

[0243] If the reception moment of the LP WUS is in the first time domain range as shown in FIGS. 2B-2F, the wake-up latency of the LP WUS to wake up the UE is considered to be Tprocess, wherein Tprocess is the time length of the UE to demodulate the LP WUS information after receiving the LP WUS signal. (That is, it is considered that the UE is in an active state within the first time domain range, and after the UE completes the demodulation of the LP WUS information, it can normally perform data transmission and reception.)

[0244] The semi-persistent channel is SPS PDSCH, CG PUSCH, SPS CSI report sent on PUSCH, SPS CSI report sent on PUCCH, etc.

[0245] The reception moment of the LP WUS can be the end moment of the LP WUS. If the UE does not need to receive the entire LP WUS signal, but only needs to receive part of the LP WUS signal to demodulate the wake-up information corresponding to itself. For example, the LP WUS signal starts at t0 moment and ends at t1 moment, the wake-up information corresponding to UE1 is located at t0-t1 UE1, and t1 UE1 < t1, then the reception moment of the LP WUS refers to the end moment of the information corresponding to the UE in the LP WUS signal, that is, the moment of t1 UE1 in the above example.

[0246] The first time domain range comprises a T1 moment before the beginning of the semi-persistent channel to the beginning moment of the semi-persistent channel, and / or the end moment of the semi-persistent channel to a T2 moment after the end moment.

[0247] In some embodiments, T1 and T2 can be the same or different. T1 corresponds to the aforementioned first time duration. T2 corresponds to the aforementioned second time duration.

[0248] In some embodiments, T1 / T2 is configured by network or defined by protocol. T1 / T2 can be related to UE wake-up capability. UE can report UE capability on T1 / T2. In theory, when UE has strong wake-up capability (i.e. UE can wake up in a very short time period), T1 / T2 can be shorter.

[0249] One special case is T1 = 0, i.e. the reception time of LP WUS is the same as the start time of the semi-persistent channel. Another special case is T2 = 0, i.e. the reception time of LP WUS is the same as the end time of the semi-persistent channel.

[0250] Embodiment 4:

[0251] If the reception time of LP WUS is in the first time domain range as shown in FIG. 2C to FIG. 2F, the wake-up latency of the UE woken up by the LP WUS is T3, which is a fixed value defined by protocol or configured by the base station. When the reception time of the LP WUS is not in the first time domain range, the wake-up latency of the UE woken up by the LP WUS is considered to be T4. T3 < T4. That is, it is considered that in the first time domain range, the UE is considered to be in an active state or a partially active state, so the state transition time is relatively general wake-up latency. Exemplarily, T4 here is one of the aforementioned third time delays, and T3 is one of the aforementioned second time delays.

[0252] In some embodiments, the semi-persistent channel is SPS PDSCH, CG PUSCH, SPS CSI report sent on PUSCH, SPS CSI report sent on PUCCH, etc.

[0253] In some embodiments, the reception time of the LP WUS can be the end time of the LP WUS. If the UE does not need to receive the entire LP WUS signal, but only needs to receive part of the LP WUS signal to demodulate the wake-up information corresponding to itself, the reception time of the LP WUS refers to the end time of the information corresponding to the UE in the LP WUS signal.

[0254] In some embodiments, the first time domain range includes T1 time before the start of the semi-persistent channel to the start time of the semi-persistent channel, and / or the end time of the semi-persistent channel to T2 time after the end time.

[0255] In some embodiments, T1 and T2 can be the same or different.

[0256] T1 / T2 is configured by network or defined by protocol. T1 / T2 can be related to UE wake-up capability. UE can report its capability on T1 / T2. In theory, when UE has strong wake-up capability (i.e. UE can wake up in a very short time period), T1 / T2 can be shorter.

[0257] One special case is T1 = 0, i.e. the reception time of LP WUS is the same as the start time of the semi-persistent channel. Another special case is T2 = 0, i.e. the reception time of LP WUS is the same as the end time of the semi-persistent channel.

[0258] Embodiment 5:

[0259] If the reception time of LP WUS is in the first time domain range as shown in FIG. 2C to FIG. 2F, the wake-up latency of UE woken up by LP WUS is T3 + Tprocess, T3 is a fixed value defined by protocol or configured by base station, where Tprocess is the time length for UE to demodulate LP WUS information after receiving LP WUS signal. When the reception time of LP WUS is not in the first time domain range, the wake-up latency of UE woken up by LP WUS is considered as T4. T3 < T4. In the first time domain range, it is considered that UE has been in active state or partially active state, so the state transition time is smaller than the general wake-up latency (i.e. T4), and after adding the demodulation time length Tprocess of LP WUS, normal data transmission and reception can be performed.

[0260] The semi-persistent channel is SPS PDSCH, CG PUSCH, SPS CSI report sent on PUSCH, SPS CSI report sent on PUCCH, etc.

[0261] The reception time of LP WUS can be the end time of LP WUS. If UE does not need to receive the entire LP WUS signal, but only needs to receive part of the LP WUS signal to demodulate the wake-up information corresponding to itself, the reception time of LP WUS refers to the end time of the information corresponding to the UE in the LP WUS signal.

[0262] The first time domain range includes T1 time before the start of the semi-persistent channel to the start time of the semi-persistent channel, and / or the end time of the semi-persistent channel to T2 time after the end time.

[0263] In some embodiments, T1 and T2 can be the same or different.

[0264] In some embodiments, T1 / T2 has network configuration or protocol definition. T1 / T2 may be related to UE wake-up capability. The UE can report UE capabilities regarding T1 / T2. Theoretically, when the UE has strong wake-up capability (i.e., the UE can wake up very quickly), the duration of T1 / T2 will be shorter.

[0265] One special case is T1=0, meaning the reception time of LP WUS is the same as the start time of the semi-persistent channel. Another special case is T2=0, meaning the reception time of LP WUS is the same as the end time of the semi-persistent channel.

[0266] Example 6:

[0267] If the reception time of LP WUS is within the first time domain, and if the end time of LP WUS is before the nearest semi-persistent channel, as shown in Figures 2C and / or 2E, then the wake-up delay for LP WUS to wake up the UE is considered to be min(the distance between the end position of LP WUS and the start time of the nearest semi-persistent channel, or the wake-up delay defined by the protocol or configured by the base station). If the end time of LP WUS is after the nearest semi-persistent channel, as shown in Figures 2D and / or 2F, then the wake-up delay for LP WUS to wake up the UE is considered to be min(the distance between the end position of LP WUS and the end time of the nearest semi-persistent channel, or the wake-up delay defined by the protocol or configured by the base station).

[0268] Semi-persistent channels include SPS PDSCH, CG PUSCH, SP CSI reports transmitted on PUSCH, and SP CSI reports transmitted on PUCCH.

[0269] The reception time of LP WUS can be the end time of LP WUS. If the UE does not need to receive the entire LP WUS signal, but only needs to receive a portion of the LP WUS signal to demodulate the wake-up information corresponding to itself, then the reception time of LP WUS refers to the end time of the information corresponding to the UE in the LP WUS signal.

[0270] The first time domain range includes time T1 before the start of the semi-persistent channel to the start time of the semi-persistent channel, and / or time T2 after the end time of the semi-persistent channel.

[0271] T1 and T2 can be the same or different.

[0272] T1 / T2 has network configuration or protocol definition. T1 / T2 can be related to UE wake-up capability. The UE can report UE capabilities regarding this T1 / T2. Theoretically, when the UE's wake-up capability is strong (i.e., the UE can wake up very quickly), the duration of T1 / T2 will be shorter.

[0273] One special case is T1 = 0, i.e., the reception time of the LP WUS is the same as the start time of the semi-persistent channel. Another special case is T2 = 0, i.e., the reception time of the LP WUS is the same as the end time of the semi-persistent channel.

[0274] In some embodiments, if the reception time of the LP WUS is in the first time domain range, if the end time of the LP WUS is before the nearest semi-persistent channel, as shown in FIG. 2C and / or FIG. 2E, the wake-up latency of the UE woken up by the LP WUS is min (the distance between the end position of the LP WUS and the start time of the nearest semi-persistent channel + Tprocess, the protocol-defined or base station-configured wake-up latency). If the end time of the LP WUS is after the nearest semi-persistent channel, as shown in FIG. 2D and / or FIG. 2F, the wake-up latency of the UE woken up by the LP WUS is min (the distance between the end position of the LP WUS and the end time of the nearest semi-persistent channel + Tprocess, the protocol-defined or base station-configured wake-up latency). Wherein Tprocess is the time length of the UE in receiving the LP WUS signal to demodulate the LP WUS information.

[0275] The semi-persistent channel is SPS PDSCH, CG PUSCH, SPS CSI report sent on PUSCH, SPS CSI report sent on PUCCH, etc.

[0276] The reception time of the LP WUS can be the end time of the LP WUS. If the UE does not need to receive the entire LP WUS signal, but only needs to receive part of the LP WUS signal to demodulate the wake-up information corresponding to itself, the reception time of the LP WUS refers to the end time of the information corresponding to the UE in the LP WUS signal.

[0277] The first time domain range includes the T1 time before the start of the semi-persistent channel to the start time of the semi-persistent channel, and / or the end time of the semi-persistent channel to the T2 time after the end time.

[0278] T1 and T2 can be the same or different.

[0279] T1 / T2 is network-configured or protocol-defined. T1 / T2 can be related to the UE wake-up capability. The UE can report the UE capability about T1 / T2. In theory, when the UE wake-up capability is strong (i.e., the UE can wake up in a very short period), the time length of T1 / T2 will be shorter.

[0280] One special case is T1 = 0, i.e., the reception time of the LP WUS is the same as the start time of the semi-persistent channel.

[0281] Another special case is T2 = 0, i.e., the reception time instant of the LP WUS is the same as the end time instant of the semi-persistent channel.

[0282] Any one of the above embodiments can be combined with each other without conflict and contradiction.

[0283] The embodiments of the present disclosure further provide a device for implementing any one of the above methods, for example, a device comprising units or modules for implementing the steps performed by the UE in any one of the above methods. For another example, another device is provided, comprising units or modules for implementing the steps performed by the network device (e.g., an access network device, or a core network device, etc.) in any one of the above methods.

[0284] It should be understood that the division of units or modules in the above device is only a logical function division, and all or part of them can be integrated into one physical entity, or can be physically separated.

The processor invokes the instructions stored in the memory to implement any one of the above methods or to implement the functions of the units or modules of the device, wherein the processor is, for example, a general processor such as a central processing unit (CPU) or a microprocessor, and the memory is a memory within the device or a memory outside the device. Alternatively, the units or modules in the device can be implemented in the form of hardware circuit, and the functions of part or all of the units or modules can be implemented by the design of the hardware circuit.
