Description

State determination method, device, and storage medium Technical Field

[0001] The present disclosure relates to the field of communication technologies, and in particular to a state determination method, device, and storage medium. Background Art

[0002] In wireless communication systems, to reduce the power consumption of terminal devices, the 3rd Generation Partnership Project (3GPP) introduced a wake-up signal (WUS). This wake-up signal can be a low-power detection signal. For example, this wake-up signal can also be called a low-power wake-up signal (LP WUS). If the terminal device detects the wake-up signal, it can monitor the physical downlink control channel (PDCCH). If the terminal device does not detect the wake-up signal, it can skip monitoring the PDCCH, thereby entering a low-power sleep state and reducing the power consumption of the terminal device.

[0146] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0147] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are examples. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationship between the entities is an example. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0148] The 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 (registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X), systems utilizing other communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0149] In some embodiments of the present disclosure, the terminal device shown in FIG1 may be a terminal device that supports a power saving function. For example, when no data is being sent or received, the terminal device may be in a sleep state of varying degrees. In one implementation, the sleep state of the terminal device may include at least one of ultra-deep sleep, deep sleep, light sleep, and micro sleep.

[0150] In some embodiments, the terminal device may be a terminal device that supports a low power wake-up signal LP WUS. The LP WUS signal uses a separate receiver, which may be referred to as LP-WUR. The terminal device may use the main radio (MR) to process downlink and / or uplink data normally. The WUS signal may be used in states such as RRC connected, RRC inactive, and RRC idle. In some embodiments, the LP WUS signal can instruct the main radio of the terminal device to switch between any two of the above sleep states, and can also instruct the terminal device to wake up or not. If the terminal device receives a WUS signal indicating wake-up, the main radio will be turned on to receive and process downlink and / or uplink signals. If the WUS signal is not received, or the WUS indicates not to wake up, the terminal device will maintain the current sleep state of the main radio.

[0151] In some embodiments, the LP WUR can operate in two modes: always on and duty cycle. In always on mode, the terminal device's LP WUR is always on, and the network device can send an LP WUS to wake the terminal device at any time. In duty cycle mode, the terminal device, based on a certain mechanism, only turns on the LP WUR during the LP WUS listening window, and the network device can only send an LP WUS to wake the terminal device during this time period.

[0152] In some embodiments, after the terminal device is instructed to activate the LP WUS configuration, the MR will enter sleep mode. At this time, uplink transmission cannot be sent, that is, the terminal device cannot perform HARQ-ACK feedback during this period. Assuming that the terminal device has not correctly received the PDSCH before, the network device needs to schedule the retransmission of the PDSCH after the terminal device feeds back NACK, and once the LP WUS configuration is activated first, this process will not be completed. Assuming that the terminal device correctly receives the PDSCH before, after the terminal device feeds back ACK to the network device, the scheduling process has been completed, and the activation of the LP WUS configuration does not affect the previous scheduling. Therefore, how to achieve management between LP WUS configuration activation and HARQ feedback is called an urgent problem to be solved.

[0153] FIG2 is a flow chart of a method for determining a state according to an embodiment of the present disclosure. The method may be performed by the above-mentioned communication system. As shown in FIG2 , the method may include:

[0154] Step S2101: The network device sends first information to the terminal device.

[0155] In some embodiments, the terminal device may receive the first information. For example, the terminal device may receive the first information sent by the network device. For another example, the terminal device may also receive the first information sent by another entity.

[0156] In some embodiments, the first information can be used to determine whether the terminal device desires to enter the first state.

[0157] In some embodiments, the first information can be used to instruct the terminal device to enter the first state.

[0158] In some embodiments, “expecting to enter the first state” can be interpreted as anticipating entering the first state, preparing to enter the first state, or being instructed to enter the first state.

[0159] In some embodiments, the first state may be a state in which the terminal device activates a wake-up signal WUS. Optionally, the wake-up signal may be a low power wake-up signal LP WUS or a common wake-up signal.

[0160] In some embodiments, the first state may be a sleep state of a main radio (MR). For example, in the first state, the main radio remains in a sleep state and does not transmit uplink and / or downlink signals. The sleep state of the main radio MR may include at least one of ultra-deep sleep, deep sleep, light sleep, and micro sleep.

[0161] In some embodiments, the name of the first information is not limited, for example, it can be "wake-up signal indication information", "low power wake-up signal indication information", "LP WUS indication information", "wake-up signal activation indication information", "low power wake-up signal activation indication information", "LP WUS activation indication information", etc.

[0162] In some embodiments, the name of the first state is not limited, for example, it can be "wake-up signal activation state", "low power wake-up signal activation state", "LP WUS activation state", "main radio sleep state", "LP WUR activation", "LP WUS configuration activation", "L WUR turn-on activation", "LP WUS listening activation", "MR sleep activation", etc.

[0163] In some embodiments, the network device may send a first message, which may include the first information. For example, the network device may send the first message to the terminal device. Optionally, the terminal device may receive the first message.

[0164] The first message may include at least one of a radio resource control RRC (Radio Resource Control) message, a medium access control control element MAC CE (Medium Access Control Control Element), downlink control information DCI (Downlink Control Information), or other messages sent by a network device to a terminal device.

[0165] In some embodiments, step S2101 is an optional step, and the terminal device may obtain the first information by receiving the first information sent by the network device, or the terminal device may obtain the first information autonomously.

[0166] In one implementation, the terminal device may receive the first information sent by the network device.

[0167] For example, the terminal device may receive first information (eg, LP WUS indication information) sent by a network device (eg, a base station). The first information may be used to instruct the terminal device to enter a first state (eg, activate LP WUS).

[0168] In another implementation manner, the terminal device may autonomously obtain the first information.

[0169] For example, the first information may be transmission information or state information of the terminal device itself, and the terminal device may autonomously determine whether it desires to enter the first state, for example, whether it desires to autonomously activate a wake-up signal, based on the first information.

[0170] Step S2102: The terminal device determines whether to enter the first state.

[0171] In some embodiments, the terminal device may determine whether to enter the first state based on the first information. Alternatively, the terminal device may not consider the first condition and determine whether to enter the first state based solely on the first information. For example, if the terminal device determines based on the first information that it is desired to enter the first state, the terminal device may enter the first state; or if the terminal device determines based on the first information that it is not desired to enter the first state, the terminal device may not enter the first state.

[0172] In some embodiments, the terminal device may determine whether to enter the first state based on a first condition. Alternatively, the terminal device may determine whether to enter the first state based solely on the first condition, without considering the first information. For example, if the first condition determines that the terminal device is performing a PDSCH transmission, the terminal device may not enter the first state; or if the first condition determines that the terminal device is performing a PUSCH transmission, the terminal device may not enter the first state.

[0173] In some embodiments, the terminal device may determine whether to enter the first state based on the first information and the first condition.

[0174] In some embodiments, the first condition can be used to determine whether the terminal device is performing physical downlink shared channel PDSCH (Physical Downlink Shared Channel) transmission.

[0175] In some embodiments, the first condition can be used to determine whether the terminal device is performing physical uplink shared channel PUSCH (Physical Uplink Shared Channel) transmission.

[0176] In some embodiments, the first condition can be used to determine whether the terminal device is performing physical downlink control channel (PDCCH) transmission.

[0177] In some embodiments, the first condition can be used to determine whether the terminal device is performing physical uplink control channel PUCCH (Physical Uplink Control Channel) transmission.

[0178] In some embodiments, the first condition may be used to determine that the terminal device has not sent Hybrid Automatic Repeat Request (HARQ) feedback information corresponding to the PDSCH transmission.

[0179] In some embodiments, the first condition may be used to determine that the terminal device has received a PDSCH transmission and has not sent HARQ feedback information corresponding to the PDSCH transmission.

[0180] In some embodiments, the name of the first condition is not limited, for example, it can be "PDSCH transmission incomplete condition", "PDSCH transmission no feedback condition", "wake-up signal activation blocking condition", "MR sleep blocking condition", etc.

[0181] In some embodiments, the terms "PDSCH transmission", "DL data", "DL signal", "DL message", "downlink data", "downlink signal", "downlink message" and the like are interchangeable. In some embodiments, the terms "PUSCH transmission", "UL data", "UL signal", "UL message", "uplink data", "uplink signal", "uplink message" and the like are interchangeable.

[0182] In this way, the terminal device can flexibly determine whether to enter the first state based on the first information and the first condition, thereby improving the reliability of PDSCH transmission.

[0183] In some embodiments, the first condition may include at least one of the following:

[0184] A PDSCH transmission is received and PDSCH decoding is not completed before obtaining the first information;

[0185] receiving a PDSCH transmission and performing PDSCH decoding before obtaining the first information;

[0186] A PDSCH transmission is received and PDSCH decoding fails before obtaining the first information;

[0187] A PDSCH transmission is received and the PDSCH is successfully decoded before obtaining the first information;

[0188] A PDSCH transmission is received and no HARQ feedback information corresponding to the PDSCH transmission is sent;

[0189] A PDSCH transmission is received and a NACK corresponding to the PDSCH transmission is sent.

[0190] For example, the first condition may include: receiving PDSCH transmission, completing PDSCH decoding before acquiring the first information, and not sending HARQ feedback information corresponding to the PDSCH transmission, and the HARQ feedback information is ACK or NACK.

[0191] For another example, the first condition may include: receiving a PDSCH transmission, completing PDSCH decoding and sending a NACK corresponding to the PDSCH transmission before acquiring the first information.

[0192] For another example, the first condition may include: receiving a PDSCH transmission, and before acquiring the first information, PDSCH decoding fails and a NACK corresponding to the PDSCH transmission is not sent.

[0193] For another example, the first condition may include: receiving a PDSCH transmission, and before acquiring the first information, PDSCH decoding fails and a NACK corresponding to the PDSCH transmission has been sent.

[0194] For another example, the first condition may include: receiving a PDSCH transmission, successfully decoding the PDSCH and not sending an ACK corresponding to the PDSCH transmission before acquiring the first information.

[0195] For another example, the first condition may include: receiving a PDSCH transmission, not completing PDSCH decoding and not sending HARQ feedback information corresponding to the PDSCH transmission before acquiring the first information.

[0196] For another example, the first condition may include: receiving a PDSCH transmission, sending a NACK corresponding to the PDSCH transmission, and not receiving a PDSCH retransmission.

[0197] For another example, the first condition may include: receiving a PDSCH transmission, sending a NACK corresponding to the PDSCH transmission, receiving a PDSCH retransmission, and not sending HARQ feedback information corresponding to the PDSCH retransmission.

[0198] For another example, the first condition may include: the terminal device needs to send HARQ feedback information, but has not yet sent the HARQ feedback information.

[0199] For another example, the first condition may include: the terminal device does not receive PDSCH transmission within a first time range.

[0200] For another example, the first condition may include: the terminal device does not receive the PDCCH within a first time range.

[0201] For another example, the first condition may include: the terminal device does not send PUSCH within a first time range.

[0202] For another example, the first condition may include: the terminal device does not send PUCCH within a first time range.

[0203] It should be noted that the first condition is not limited to the above examples and can be combined arbitrarily.

[0204] Optionally, the above-mentioned completion of PDSCH decoding can be PDSCH decoding success or PDSCH decoding failure. Optionally, "PDSCH decoding failure" can also be referred to as "failure to correctly decode PDSCH". Optionally, "PDSCH decoding success" can also be referred to as "correct PDSCH decoding". Optionally, the above-mentioned HARQ feedback information can be ACK or NACK.

[0205] Optionally, the first time range may be a time range pre-set by the protocol, or a time range determined by the network device and sent to the terminal device, or a time range determined autonomously by the terminal device.

[0206] In some embodiments, the above-mentioned first condition can be used to determine whether the terminal device is performing PDSCH transmission. For example, if the terminal device meets the above-mentioned first condition, it can be determined that the terminal device is performing PDSCH transmission.

[0207] In some embodiments, the terminal device may determine that it desires to enter the first state based on first information; and determine whether to enter the first state based on a first condition. Optionally, when the terminal device determines that it desires to enter the first state based on the first information, it determines whether to enter the first state based on the first condition. Optionally, in response to determining that it desires to enter the first state based on the first information, the terminal device determines whether to enter the first state based on the first condition. Optionally, when the terminal device determines that it desires to enter the first state based on the first information, it determines whether to enter the first state based on the first condition.

[0208] In this way, the terminal device can flexibly determine whether to enter the first state based on the first information and the first condition, thereby avoiding the activation wake-up signal affecting the HARQ feedback and improving the reliability of PDSCH transmission.

[0209] In some embodiments, if the terminal device determines that it does not want to enter the first state based on the first information, it may not enter the first state and does not need to continue to perform subsequent actions. For example, it may not need to determine whether to enter the first state based on the first condition.

[0210] In some embodiments, the terminal device may determine whether to enter the first state based on the first condition by: determining that the terminal device is performing PDSCH transmission based on the first condition, and entering the first state. Alternatively, determining that the terminal device is performing PDSCH transmission based on the first condition, and entering the first state. Alternatively, determining that the terminal device is performing PDSCH transmission based on the first condition, and entering the first state. Alternatively, determining that the terminal device is performing PDSCH transmission based on the first condition, and entering the first state.

[0211] It should be noted that determining that the terminal device is performing PDSCH transmission based on the first condition can also be referred to as the terminal device satisfying the first condition. For example, when the terminal device satisfies the above-mentioned first condition, it enters the first state.

[0212] In other embodiments, the manner in which the terminal device determines whether to enter the first state according to the first condition may be: determining, according to the first condition, that the terminal device is currently transmitting PDSCH, and not entering the first state. Alternatively, determining, according to the first condition, that the terminal device is currently transmitting PDSCH, and not entering the first state. Alternatively, determining, according to the first condition, that the terminal device is currently transmitting PDSCH, and not entering the first state. Alternatively, determining, according to the first condition, that the terminal device is currently transmitting PDSCH, and not entering the first state.

[0213] It should also be noted that determining that the terminal device is performing PDSCH transmission based on the first condition can also be referred to as the terminal device satisfying the first condition. For example, when the terminal device satisfies the above-mentioned first condition, it does not enter the first state.

[0214] In some embodiments, when the terminal device determines to enter the first state based on the first information and the first condition, at least one of step S2103 and step S2104 can be executed.

[0215] In some embodiments, when the terminal device determines not to enter the first state based on the first information and the first condition, at least one of step S2105, step S2106, and step S2107 may be executed.

[0216] In some embodiments, when the terminal device determines that it desires to enter the first state based on the first information, and determines not to enter the first state based on the first condition, at least one of step S2105, step S2106, and step S2107 may be executed.

[0217] In some embodiments, the terminal device determines that it does not want to enter the first state based on the first information, and may not enter the first state. For example, step S2105 may be executed and other steps in this embodiment may not be executed.

[0218] Step S2103: The terminal device enters the first state.

[0219] In some embodiments, the terminal device may activate a wake-up signal.

[0220] In some embodiments, the terminal device may enter a state where the main radio is asleep.

[0221] In some embodiments, the terminal device may discard HARQ feedback information corresponding to the PDSCH transmission, and the HARQ feedback information may be ACK or NACK.

[0222] For example, the terminal device may activate LP WUS and discard HARQ-ACK feedback.

[0223] For another example, the terminal device may activate LP WUS, and when the terminal device needs to feedback ACK, the HARQ-ACK feedback is discarded.

[0224] It should be noted that the order in which the terminal device enters the first state and discards the HARQ feedback information can be swapped or performed simultaneously. For example, the terminal device may first enter the first state and then discard the HARQ feedback information; the terminal device may first discard the HARQ feedback information and then enter the first state; or the terminal device may simultaneously enter the first state and discard the HARQ feedback information. Similarly, the terminal device may discard the HARQ feedback information before, after, or simultaneously with exiting the first state in step S2104.

[0225] In one implementation, the terminal device enters a first state and discards the NACK corresponding to the PDSCH transmission.

[0226] In another implementation, the terminal device enters the first state and discards the ACK corresponding to the PDSCH transmission.

[0227] In another implementation, the terminal device enters the first state and discards HARQ feedback information corresponding to the PDSCH transmission. The HARQ feedback information can be ACK or NACK.

[0228] Step S2104: The terminal device exits the first state.

[0229] In some embodiments, the terminal device may deactivate the wake-up signal.

[0230] In some embodiments, the terminal device may exit the main radio sleep state, for example, may activate the main radio and transmit uplink signals and / or downlink signals via the main radio.

[0231] In some embodiments, the terminal device can exit the first state autonomously. For example, if there is uplink data to be sent, the terminal device can exit the first state.

[0232] In other embodiments, the terminal device may receive second information sent by the network device and exit the first state based on the second information. The second information may be used to instruct the terminal device to exit the first state. For example, the second information may be a wake-up signal, and the terminal device may exit the first state after receiving the wake-up signal.

[0233] In some embodiments, after the terminal device exits the first state, it may send HARQ feedback information corresponding to the above-mentioned PDSCH transmission, and the HARQ feedback information may be ACK or NACK.

[0234] For example, before the terminal device enters the first state, there is a PDSCH transmission without sending HARQ feedback information. After the terminal device exits the first state, it can continue to send the HARQ feedback information corresponding to the PDSCH transmission.

[0235] In this way, HARQ feedback can be completed and the reliability of PDSCH transmission can be improved.

[0236] In one implementation, after exiting the first state, the terminal device may send a NACK corresponding to the PDSCH transmission. This NACK can instruct the network device to retransmit the PDSCH transmission, improving the reliability of the PDSCH transmission. Alternatively, the terminal device may not need to send an ACK corresponding to the PDSCH transmission, i.e., discard the ACK.

[0237] Optionally, after the terminal device sends the NACK corresponding to the PDSCH transmission, it can receive the PDSCH retransmission sent by the network device based on the NACK. If the retransmission is successful, the ACK corresponding to the PDSCH retransmission can be sent; if the retransmission fails, the NACK corresponding to the PDSCH retransmission can be sent until the retransmission is successful or the maximum number of retransmissions is reached. The maximum number of retransmissions can be the number pre-set by the protocol, or the number determined by the network device and sent to the terminal device, or the number determined autonomously by the terminal device. In this way, PDSCH retransmission can be achieved after exiting the first state, thereby improving the reliability of PDSCH transmission.

[0238] In another implementation, after exiting the first state, the terminal device may send an ACK corresponding to the PDSCH transmission. This ACK notifies the network device that the PDSCH transmission has been correctly received, eliminating the need for the network device to retransmit the PDSCH transmission, thereby improving PDSCH transmission efficiency. Alternatively, the terminal device may not send a NACK corresponding to the PDSCH transmission, i.e., discard the NACK.

[0239] In another implementation, after exiting the first state, the terminal device may send HARQ feedback information corresponding to the PDSCH transmission. The HARQ feedback information may be an ACK or a NACK. In this way, the ACK or NACK can be used to inform the network device whether the PDSCH transmission was correctly received, thereby improving the reliability of the PDSCH transmission.

[0240] In some embodiments, when the primary radio of the terminal device is woken up again, the terminal device may send a NACK to the network device. Optionally, the terminal device may send the NACK to the network device in the first available time slot, which is the first time slot capable of sending PUSCH / PUCCH.

[0241] In some embodiments, the terminal device may determine whether to send HARQ feedback information based on the duration of the first state, which may be the time difference between the moment the terminal device exits the first state and the moment it enters the first state.

[0242] For example, if the duration that the terminal device is in the first state is greater than or equal to the first duration, the HARQ feedback information may be discarded.

[0243] For another example, if the duration that the terminal device is in the first state is less than the first duration, HARQ feedback information can be sent.

[0244] The first duration is a duration pre-set by the protocol; or, the first duration is a duration determined by the network device and sent to the terminal device; or, the first duration is a duration determined by the terminal device and sent to the network device.

[0245] For example, the first duration may be a parameter preset by a protocol, and both the terminal device and the network device determine the first duration according to the protocol.

[0246] For another example, the first duration may be a parameter preset by the network device. Optionally, the network device may send the first duration to the terminal device.

[0247] For another example, the first duration may be a parameter preset by the terminal device. Optionally, the terminal device may send the first duration to the network device.

[0248] Step S2105: The terminal device does not enter the first state.

[0249] In some embodiments, the terminal device may not activate the wake-up signal.

[0250] In some embodiments, the terminal device may not enter a state where the main radio is asleep.

[0251] In some embodiments, the terminal device may stop activating the wake-up signal.

[0252] In some embodiments, the terminal device may stop entering a state where the main radio is asleep.

[0253] Step S2106: The terminal device enters the first state according to the second condition.

[0254] In some embodiments, the second condition may be used to determine that the terminal device has sent corresponding HARQ feedback information for the PDSCH transmission.

[0255] In some embodiments, the second condition may be used to determine that the terminal device has completed PDSCH transmission.

[0256] In some embodiments, the name of the second condition is not limited, for example, it can be "PDSCH transmission completion condition", "HARQ feedback completion condition", "wake-up signal activation condition", "MR sleep condition", etc.

[0257] In this way, the terminal device may not enter the first state when the first condition is met, and enter the first state after the second condition is met, thereby avoiding the problem of transmission failure caused by entering the first state (for example, activating the wake-up signal) and improving the reliability of PDSCH transmission.

[0258] In some embodiments, the second condition includes at least one of the following:

[0259] PDSCH decoding is completed, and HARQ feedback information corresponding to the PDSCH transmission is sent. The HARQ feedback information is an ACK or NACK;

[0260] The PDSCH transmission is retransmitted and HARQ feedback information corresponding to the retransmission is sent.

[0261] In one implementation, the second condition may include: PDSCH decoding is completed, and HARQ feedback information corresponding to the PDSCH transmission is sent, where the HARQ feedback information is ACK or NACK.

[0262] In another implementation, the second condition may include: completing retransmission of the PDSCH transmission and sending HARQ feedback information corresponding to the retransmission.

[0263] In another implementation, the second condition may include: PDSCH decoding is completed, a NACK corresponding to the PDSCH transmission is sent, retransmission of the PDSCH transmission is completed based on the NACK feedback, and HARQ feedback information corresponding to the retransmission is sent.

[0264] In some embodiments, the method of retransmitting PDSCH transmission may include: if PDSCH decoding fails or decoding is not completed, after the terminal device sends NACK, it can receive PDSCH retransmission sent by the network device based on the NACK. If the retransmission is successful, the ACK corresponding to the PDSCH retransmission can be sent; if the retransmission fails, the NACK corresponding to the PDSCH retransmission can be sent until the retransmission is successful or the maximum number of retransmissions is reached.

[0265] In some embodiments, when the terminal device determines that it expects to enter the first state based on the first information, it may not enter the first state if the first condition is met, and may send HARQ feedback. After completing sending the HARQ feedback, it may enter the first state again.

[0266] In other embodiments, when the terminal device determines that it expects to enter the first state based on the first information, it may not enter the first state if the first condition is met, and send HARQ feedback. When the HARQ feedback is completed and the HARQ feedback is ACK, it enters the first state again.

[0267] In some other embodiments, when the terminal device determines based on the first information that it desires to enter the first state, it may not enter the first state if the first condition is met, and may enter the first state after completing the retransmission of the PDSCH transmission. For example, when the terminal device needs to send a NACK, it may not enter the first state, and may enter the first state after completing the retransmission scheduling, that is, completing the sending of the HARQ feedback corresponding to the PDSCH retransmission and the HARQ feedback is ACK.

[0268] Step S2107: The terminal device exits the first state.

[0269] In some embodiments, the terminal device may deactivate the wake-up signal.

[0270] In some embodiments, the terminal device may exit the main radio sleep state, for example, may activate the main radio and transmit uplink signals and / or downlink signals via the main radio.

[0271] In some embodiments, the terminal device can exit the first state autonomously. For example, if there is uplink data to be sent, the terminal device can exit the first state.

[0272] In other embodiments, the terminal device may receive second information sent by the network device and exit the first state based on the second information. The second information may be used to instruct the terminal device to exit the first state. For example, the second information may be a wake-up signal, and the terminal device may exit the first state after receiving the wake-up signal.

[0273] The method involved in the embodiments of the present disclosure may include at least one of the above steps S2101 to S2107. For example, step S2102 can be implemented as an independent embodiment, step S2105 can be implemented as an independent embodiment, steps S2102+S2105 can be implemented as an independent embodiment, steps S2102+S2103 can be implemented as an independent embodiment, steps S2103+S2104 can be implemented as an independent embodiment, steps S2105+S2106 can be implemented as an independent embodiment, steps S2102+S2103+S2104 can be implemented as an independent embodiment, steps S2102+S2105+S2106 can be implemented as an independent embodiment, steps S2105+S2106+S2107 can be implemented as an independent embodiment, and steps S2102+S2105+S2106+S2107 can be implemented as an independent embodiment, but are not limited thereto.

[0411] FIG6 is a flow chart of a state determination method according to an embodiment of the present disclosure. As shown in FIG6 , the embodiment of the present disclosure relates to a state determination method, which can be executed by a communication system and can include:

[0412] Step S6101: The terminal device determines whether to enter the first state.

[0413] In some embodiments, terms such as "entering the first state", "activating LP WUS", "LP WUR activation", "LP WUS configuration activation", "LP WUR turn-on activation", "LP WUS listening activation", and "MR sleep activation" can be used interchangeably.

[0414] In some embodiments, a network device can wake up terminal devices in the cell that support LP WUS or change the sleep state of these terminal devices by sending an LP WUS. For terminal devices that support LP WUS, at least one LP WUS signal is received through an LP WUR, and the MR wakes up or changes its sleep state based on the information carried by the received LP WUS signal. The change in the MR's sleep state refers to switching between states such as super deep sleep, deep sleep, light sleep, and shallow sleep, and the awakening of the MR refers to the transition of the MR from any sleep state to the awake state.

[0415] The terminal device receives LP WUS indication information configured by the network device, where the LP WUS indication information is used to indicate LP WUS activation. Alternatively, the terminal device proactively activates the LP WUS. Equivalent descriptions of LP WUS activation include LP WUR activation, LP WUS configuration activation, L WUR on-activation, LP WUS listening activation, and MR sleep activation. When LP WUS activation conflicts with HARQ-ACK, that is, when HARQ-ACK feedback is pending before LP WUS activation, it can be determined whether to enter the first state, that is, whether to activate LP WUS.

[0416] In one implementation, when the terminal device meets the first condition, the LP WUS may be deactivated and the HARQ-ACK feedback may be sent first. Further, after the HARQ-ACK feedback is completed, the LP WUS may be activated.

[0417] The first condition may include at least one of the following:

[0418] The terminal device receives the PDSCH sent by the network device and fails to complete PDSCH decoding before receiving the LP WUS indication information (preferred condition 1);

[0419] The terminal device receives the PDSCH sent by the network device and completes PDSCH decoding before receiving the LP WUS indication information;

[0420] The terminal device receives the PDSCH sent by the network device and fails to correctly decode the PDSCH before receiving the LP WUS indication information (preferred condition 2);

[0421] The terminal device receives the PDSCH sent by the network device and correctly decodes the PDSCH before receiving the LP WUS indication information;

[0422] The terminal device needs to send a NACK to the network device and has not yet sent it (preferred condition 3);

[0423] The terminal device needs to send an ACK to the network device and has not yet sent it.

[0424] In another implementation, when the terminal device meets the first condition, the LP WUS may be deactivated and HARQ-ACK feedback may be sent first. Further, after the HARQ-ACK feedback is completed and the feedback is ACK, the LP WUS may be activated.

[0425] The first condition may include at least one of the following:

[0426] The terminal device receives the PDSCH sent by the network device and fails to complete PDSCH decoding before receiving the LP WUS indication information (preferred condition 1);

[0427] The terminal device receives the PDSCH sent by the network device and completes PDSCH decoding before receiving the LP WUS indication information;

[0428] The terminal device receives the PDSCH sent by the network device and fails to correctly decode the PDSCH before receiving the LP WUS indication information (preferred condition 2);

[0429] The terminal device receives the PDSCH sent by the network device and correctly decodes the PDSCH before receiving the LP WUS indication information;

[0430] The terminal device needs to send a NACK to the network device and has not yet sent it (preferred condition 3);

[0431] The terminal device needs to send an ACK to the network device and has not yet sent it.

[0432] In another implementation, when the terminal device meets the first condition and needs to send a NACK, the terminal device may stop activating the LP WUS. Further, after completing the retransmission scheduling, that is, feeding back an ACK, the LP WUS may be activated again.

[0433] The first condition includes at least one of the following:

[0434] The terminal device receives the PDSCH sent by the network device and fails to correctly decode the PDSCH before receiving the LP WUS indication information (preferably condition 1);

[0435] The terminal device needs to send a NACK to the network device and has not yet sent it (preferred condition 2);

[0436] In another implementation, when the terminal device meets the first condition, the LP WUS may be activated, and after the LP WUS is deactivated, HARQ-ACK feedback is performed.

[0437] The first condition may include at least one of the following:

[0438] The terminal device receives the PDSCH sent by the network device and fails to complete PDSCH decoding before receiving the LP WUS indication information (preferred condition 1);

[0439] The terminal device receives the PDSCH sent by the network device and completes PDSCH decoding before receiving the LP WUS indication information;

[0440] The terminal device receives the PDSCH sent by the network device and fails to correctly decode the PDSCH before receiving the LP WUS indication information (preferred condition 2);

[0441] The terminal device receives the PDSCH sent by the network device and correctly decodes the PDSCH before receiving the LP WUS indication information;

[0442] The terminal device needs to send a NACK to the network device and has not yet sent it (preferred condition 3);

[0443] The terminal device needs to send an ACK to the network device and has not yet sent it.

[0444] In yet another implementation, the terminal device may activate LP WUS and discard HARQ-ACK feedback.

[0445] In another implementation, the terminal device may activate LP WUS, and when the terminal device needs to feedback ACK, discard the HARQ-ACK feedback.

[0446] In another implementation, the terminal device may activate LP WUS. When the terminal device needs to feedback NACK, the terminal device may perform HARQ-ACK feedback after deactivating LP WUS.

[0447] For example, when the primary radio of the terminal device is woken up again, the terminal device may send a NACK to the network device. Alternatively, the terminal device may send a NACK to the network device in the first available time slot, which is the first time slot capable of sending PUSCH / PUCCH.

[0448] In some embodiments of the present disclosure, a communication system is provided, which may include a terminal device and a network device, wherein the terminal device can execute the status determination method executed by the terminal device in the aforementioned embodiment of the present disclosure; the network device can execute the status determination method executed by the network device in the aforementioned embodiment of the present disclosure.
