[0025] The embodiments of the present disclosure are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure and are not to be construed as limiting the present disclosure. It should be noted that the embodiments of the present disclosure and the features in the embodiments may be combined with each other unless there is a conflict.

[0026] To facilitate understanding, the terms involved in the embodiments of the present disclosure are first introduced.

[0027] 1. Low Power Wake Up Signal (LP WUS)

[0028] The LP WUS signal uses a separate receiver, called LP-WUR (or LR). The terminal needs to use the main radio (MR) to process downlink and / or uplink data normally. The LP WUS signal may be used in Radio Resource Control (RRC) connected state, inactive state, idle state, and other states. The LP WUS signal can instruct the terminal main radio to switch between any two sleep states, and can also instruct the terminal to wake up or not. If the terminal receives an LP WUS signal indicating wakeup, it will turn on the main radio to receive and process downlink and / or uplink signals. If the LP WUS signal is not received, or the LP WUS indicates not to wake up, the terminal will maintain the current sleep state of the main radio. There are 4 sleep states of MR: Ultra-deep sleep, Deep sleep, Light sleep, and Micro sleep.

[0029] 2. Low Power Wake Up Receiver (LP WUR / LR)

[0030] There are two working modes of LP WUR, one is always ON and the other is duty cycle. For the always ON mode, the LP WUR of the terminal is always in the on state, and the base station can send LP WUS to wake up the terminal at any time. For the duty cycle mode, the terminal only turns on LP WUR in the listening time window of LP WUS according to a certain mechanism, and the base station can only send LP WUS to wake up the terminal during this time period. In addition, depending on the type of supported signals, LP WUR can be divided into two categories: LP-WUR can support at least two types: a receiver that only supports envelope detection (Envelope Detection) of the on-off keying (OOK) symbols of LP WUS, hereinafter referred to as OOK LR; a receiver that supports detection of the time domain or frequency domain sequence carried by the OOK symbols of LP WUS, which can be called orthogonal frequency division multiplexing (OFDM) LR. Generally speaking, the link performance of OOK LR is relatively poor, while that of OFDM LR is better.

[0031] 3. Low Power Sync signal (LP SS)

[0032] When detecting LP WUS, the terminal needs to obtain time and frequency synchronization by detecting the synchronization signal, and then obtain the time and frequency position of the base station transmitting LP WUS. The synchronization signal can be a reused existing primary synchronization signal (PSS) and / or secondary synchronization signal (SSS), or LP SS. LP WUS / LP SS carries information through amplitude shift keying (ASK) modulation, and OOK modulation is a special case of ASK modulation. Taking OOK as an example, the OOK ON symbol and the OOK OFF symbol represent different bits, for example, OOK ON represents bit 1, and OOK OFF represents bit 0. The LP WUS information can also be encoded, with each coded bit mapped to an OOK symbol, such as Manchester coding. For 1 / 2 Manchester encoding, information bit 1 can be mapped to 2 coded bits; for 1 / 4 Manchester encoding, information bit 1 can be mapped to 4 coded bits; for 1 / 8 Manchester encoding, information bit 1 can be mapped to 8 coded bits; and for 1 / 16 Manchester encoding, information bit 1 can be mapped to 16 coded bits. Furthermore, the time or frequency domain sequence carried by each OOK symbol in LP WUS can also carry information.

Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0111] In this embodiment, the network device sends an LP WUS to the terminal to wake up the terminal. After receiving the LP WUS, the terminal can send a first message on a first transmission resource, and then the terminal can feedback a response message on a specific transmission resource, so that the network device knows that the terminal has been awakened or the sleep state of the MR has changed, which facilitates timely scheduling of the terminal.

[0112] Furthermore, to illustrate the specific execution process of the above-mentioned communication processing system, FIG2 shows a schematic diagram of a communication method according to an embodiment of the present disclosure. The method is applied to the above-mentioned communication system, as shown in FIG2, and may include the following steps:

[0113] Step S201: The network device sends an LP WUS to the terminal.

[0114] In some embodiments, the terminal receives the LP WUS sent by the network device.

[0115] In some embodiments, the LP WUS can be used to wake up the terminal. In a network, the network device can wake up the terminals that support LP WUS in the cell or change the sleep state of these terminals by sending LP WUS. For terminals that support LP WUS, at least one LP WUS signal is received through LP WUR, and the main radio (MR) wakes up or changes the sleep state according to the information carried by the received LP WUS signal. Among them, the change of the sleep state of MR refers to the mutual switching between super deep sleep, deep sleep, light sleep, shallow sleep and other states, and the awakening of MR refers to the conversion of MR from any sleep state to the awakened state.

[0116] Step S202: The terminal sends first information on a first transmission resource.

[0117] In some embodiments, the terminal may send first information on a designated first transmission resource, where the first information is used to determine response information corresponding to the LP WUS, so that the network device knows that the terminal has been awakened or the sleep state of the MR has changed.

[0118] In some embodiments, the first transmission resource may include a time-frequency domain resource, and the time-frequency domain resource is used by the terminal to send the first information.

[0119] In some examples, the network device sends an LP WUS to the terminal, which carries information for waking up the terminal. After the terminal is awakened, it sends a response message to the network device via a first message on a designated first transmission resource to inform the network device that the terminal has been awakened.

[0120] In some embodiments, the first information-bearing channel includes at least one of the following:

[0121] PUCCH; PUSCH.

[0122] For example, the bearer channel of the response information fed back by the terminal to the network device may include at least one of PUCCH and PUSCH.

[0123] In some embodiments, the first information may include at least one of the following:

[0124] Feedback Scheduling Request (FBSR); Wake-up Acknowledgement (WACK); Channel State Information (CSI).

[0125] In some examples, the FBSR may be sent on the PUCCH or PUSCH to provide feedback to the network device regarding the LP WUS response. In some examples, the WACK may be sent on the PUCCH or PUSCH to provide feedback to the network device regarding the LP WUS response. In some examples, the CSI includes the response information and may be sent on the PUCCH or PUSCH to provide feedback to the network device regarding the LP WUS response.

[0126] In some embodiments, the response information of the LP WUS may be used to provide feedback on at least one of the following:

[0127] Whether the terminal is awakened; whether the terminal successfully receives data; whether the terminal successfully receives downlink control information.

[0128] For example, the protocol predefines LP WUS response information, which can be used to feedback whether the terminal is awakened, and / or whether the terminal successfully receives data, and / or whether the terminal successfully receives downlink control information, etc.

[0129] In one implementation, a response message can be used to provide feedback that the terminal has been awakened. After receiving the LP WUS and waking up the MR, the terminal sends a response message on a first transmission resource. Upon receiving the response message on the first transmission resource, the network device determines that the terminal has been awakened. For example, the network device determines whether a response message has been sent by determining power consumption.

[0130] In one implementation, a response message is used to indicate that a terminal has been awakened. After receiving the LP WUS and waking up the MR, the terminal sends the response message on a first transmission resource. The network device receives the response message on the first transmission resource. The response message may include a terminal identifier (UE ID). The network device determines which terminal has been awakened based on the UE ID information.

[0131] In one implementation, the response information is used to provide feedback on whether the terminal successfully received data and whether the terminal has been awakened. After receiving the LP WUS and waking up the MR, the terminal sends the response information on the first transmission resource. The network device receives the response information on the first transmission resource and determines that the terminal has been awakened. Furthermore, the response information includes at least one feedback bit, which indicates whether the network device successfully received the most recently scheduled data. For example, a feedback bit equal to a1 indicates successful reception, while a feedback bit equal to b1 indicates unsuccessful reception.

[0132] In one implementation, the response information is used to provide feedback on whether the terminal successfully received the control information and whether the terminal has been awakened. After receiving the LP WUS and waking up the MR, the terminal sends the response information on the first transmission resource. The network device receives the response information on the first transmission resource and determines that the terminal has been awakened. Furthermore, the response information includes at least one feedback bit, which is used to indicate whether the network device successfully received the most recently sent downlink control information. For example, a feedback bit equal to a2 indicates successful reception, while a feedback bit equal to b2 indicates unsuccessful reception.

[0133] In some embodiments, the first transmission resource may be a designated transmission resource for sending the first information. Accordingly, there are multiple optional ways to configure the first transmission resource, such as by a network device indicating or by a protocol predefining the transmission resource. In some examples, it may specifically include at least one of A1 to D1:

[0134] A1. The terminal may determine a first transmission resource based on first signaling sent by a network device. For example, the network device may indicate, via the first signaling, a transmission resource for the terminal to send the first information, i.e., the first transmission resource. In some examples, the first signaling in A1 may include semi-static signaling and / or dynamic signaling. For example, the semi-static signaling may be RRC signaling, and the dynamic signaling may be DCI, MAC CE, etc.

[0135] B1. The terminal may determine the first transmission resource based on the time domain position of the superimposed sequence of the LP WUS in the LP WUS. For example, the protocol predefines or the network device indicates a correspondence between the time domain position of the LP WUS superimposed sequence in the LP WUS and a response resource parameter value. The response resource parameter value may be an offset value between the transmission resource used by the terminal to receive the LP WUS and the response resource. The network device may then indicate the response resource of the LP WUS, i.e., the transmission resource for the terminal to send the first information, based on the time domain position of the LP WUS superimposed sequence in the LP WUS.

[0136] In some examples, the protocol predefines a correspondence between the time domain position of the LP WUS superimposed sequence in the LP WUS and the offset value, which is shown in Table 1 or Table 2. The offset value is in time slots.

[0137] Table 1

[0138] According to the correspondence in Table 1, the network device can indicate the response resource of the LP WUS through the time domain position of the LP WUS superimposed sequence, such as obtaining the corresponding offset value according to the parity of the OFDM symbol index of the OFDM sequence superimposed in the LP WUS duration, and determine the transmission resource for the terminal to send the first information, i.e., the first transmission resource, based on the offset value and in combination with the transmission resource information used by the terminal to receive the LP WUS.

[0139] Table 2

[0140] According to the correspondence in Table 2, the network device can obtain the corresponding offset value through the time domain position of the LP WUS superimposed sequence in the LP WUS, corresponding to the response resource of the LP WUS, such as the OFDM symbol index of the OFDM sequence superimposed in the LP WUS duration, and determine the transmission resource for the terminal to send the first information, i.e., the first transmission resource, based on the offset value and in combination with the transmission resource information used by the terminal to receive the LP WUS.

[0141] C1. The terminal may determine the first transmission resource based on the listening timing of the LP WUS. For example, the protocol predefines or the network device indicates the correspondence between the listening timing of the LP WUS and the response resource. Then, the network device may indicate the listening timing of the LP WUS and the corresponding response resource of the LP WUS, that is, the transmission resource for the terminal to send the first information.

[0142] D1. Determine a first transmission resource based on adjacent available resources; for example, the protocol predefines adjacent available resources as LP WUS response resources, ie, transmission resources for the terminal to send the first information, such as but not limited to: configured grant (CG) resources that meet the timeline.

[0143] In some examples, the network device configures LP WUS response resources for the terminal supporting LP WUS through semi-static signaling, that is, transmission resources for the terminal to send the first information, such as configuring the response resources through RRC signaling.

[0144] For example, the protocol defines a first RRC signaling message, which may include at least one configuration parameter for configuring a response resource. The network device configures the response resource for a terminal supporting LP WUS through the first RRC signaling message, i.e., the response resource is configured through the first RRC signaling message. After the network device configures the response resource through the first RRC signaling message, the response resource can be used by the terminal.

[0145] In some examples, the network device indicates the response resources for the terminal supporting LP WUS through dynamic signaling, such as indicating the response resources through signaling such as DCI and MAC CE.

[0146] For example, the protocol defines a first dynamic signaling message, which includes at least one configuration parameter for configuring a response resource. The first dynamic signaling message includes at least one of a DCI and a MAC CE. The network device indicates the response resource to a terminal supporting LP WUS through the first dynamic signaling message.

[0147] In some embodiments, the first transmission resource configured by the network device may be a preconfigured resource that is unusable before activation and usable after activation. There are various optional methods for activating the configured first transmission resource. In some examples, the terminal may determine the activation of the configured first transmission resource based on second signaling sent by the network device, which may include dynamic signaling; and / or determine the activation of the configured first transmission resource after the LP WUS is activated; and / or determine the activation of the configured first transmission resource after receiving the LP WUS.

[0148] In some examples, the network device preconfigures response resources for terminals supporting LP WUS through semi-static signaling, that is, the transmission resources for the terminal to send the first information, and indicates the activation of the response resources through dynamic signaling. The activation of the response resources can be considered as the preconfigured response resources can be used.

[0149] For example, the protocol predefines a second RRC signaling message, the second RRC signaling message includes at least one configuration parameter for configuring a response resource. The protocol predefines a second dynamic signaling message, the second dynamic signaling message includes at least one activation bit for indicating whether to activate the configured response resource. The second dynamic signaling message includes at least one of a DCI message and a MAC CE message.

[0150] In some embodiments, the network device semi-statically preconfigures response resources for terminals supporting LP WUS, i.e., transmission resources for the terminal to send the first information, and implicitly indicates activation of the response resources. Activation of the response resources can be considered as the pre-configured response resources being available for use.

[0151] For example, the protocol predefines a second RRC signaling message, the second RRC signaling message includes at least one configuration parameter for configuring the response resource. The protocol predefines that the configured response resource is activated after the LP WUS is activated, or the protocol predefines that the configured response resource is activated after the terminal receives the LP WUS, etc.

[0152] In some embodiments, the first signaling of A1 may carry at least one configuration parameter, where the configuration parameter is used to configure the first transmission resource, ie, a configuration parameter of the response resource.

[0153] In some examples, the configuration parameters include at least one of A2 to H2:

[0154] A2. The time domain period of the first transmission resource. For example, the response period is the time domain period of the response resource. In some examples, the measurement unit of the response period includes at least one of a relative time unit and an absolute time unit, such as a time slot, a radio frame, a time domain symbol, milliseconds, or microseconds.

[0155] B2. A time domain offset of the first transmission resource within the time domain period. For example, the response period offset is the time domain offset of the response resource within the time domain period. In some examples, the measurement unit of the response period offset includes at least one of a relative time unit and an absolute time unit, such as a time slot, a radio frame, a time domain symbol, milliseconds, or microseconds.

[0156] C2. The time domain offset between the time domain resource location of the first transmission resource and the time domain resource location of the LP WUS. For example, the response offset is the time domain offset between the time domain resource location of the response information and the time domain resource location of the corresponding LP WUS. In some examples, the measurement unit of the response offset includes at least one of a relative time unit and an absolute time unit, such as a time slot, a radio frame, a time domain symbol, milliseconds, or microseconds.

[0157] D2: The number of consecutive time-domain symbols of the first transmission resource in the time domain. For example, the response duration is the number of consecutive time-domain symbols occupied by the response information in the time domain.

[0158] E2: The starting point of the continuous time domain symbols of the first transmission resource in the time domain, such as the starting point of the response duration, that is, the starting point of the continuous time domain symbols occupied by the response information in the time domain.

[0159] F2. Frequency-domain bandwidth information of the first transmission resource, such as the response bandwidth, i.e., the number of subcarriers or resource blocks (RBs) occupied by the response information in the frequency domain; and / or the response bandwidth starting point, i.e., the index starting point of the subcarriers or RBs occupied by the response information in the frequency domain.

[0160] G2. Resource index of the first transmission resource, such as a response resource index, indicating a specific response resource in a response information set.

[0161] H2. Response window information for the response information. For example, the response window, i.e., the time domain range in which the response information is potentially sent; and / or the response window start point, i.e., the time domain start point in the time domain range in which the response information is potentially sent; and / or the response window end point, i.e., the time domain start point in the time domain range in which the response information is potentially sent; and / or the response window index, i.e., indicating a specific response window in a response window set. In some examples, the measurement unit of the response window includes at least one of a relative time unit and an absolute time unit, such as a time slot, a radio frame, a time domain symbol, ms, us, etc.

[0162] In some embodiments, the terminal monitors downlink control information before sending the first information on the first transmission resource; or does not monitor downlink control information. For example, after waking up the MR, the terminal monitors downlink control information before sending a response message to the network device via the first information. For another example, after waking up the MR, the terminal does not monitor downlink control information before sending a response message to the network device via the first information.

[0163] In some embodiments, the network device sends downlink control information to the terminal after sending the LP WUS. For example, the network device does not need to send downlink control information to the terminal before receiving a response message sent by the terminal via the first message. For another example, the network device needs to send downlink control information to the terminal before receiving a response message sent by the terminal via the first message.

[0164] In some embodiments, after sending an LP WUS, if the network device does not receive a response from the terminal within the listening window, the network device resends the LP WUS to the terminal. For example, if the network device does not receive a response from the terminal via a first message within the listening window, the network device needs to resend the LP WUS to the terminal. For another example, if the network device does not receive a response from the terminal via a first message within the listening window, the network device needs to resend the LP WUS to the terminal at the nearest LP WUS listening opportunity.

[0165] In some embodiments, after sending an LP WUS, if the network device does not receive a response from the terminal after the maximum delay for response reception, the network device resends the LP WUS to the terminal. For example, if the network device does not receive a response from the terminal after the maximum delay, the network device needs to resend the LP WUS to the terminal. For another example, if the network device does not receive a response from the terminal after the maximum delay, the network device needs to resend the LP WUS to the terminal at the nearest LP WUS listening opportunity.

[0166] In some embodiments, after sending an LP WUS, if the network device does not receive uplink data from the terminal after the maximum delay of the data scheduling, the network device resends the LP WUS to the terminal. For example, if the network device does not receive feedback information or uplink data from the terminal after the maximum delay of the data scheduling, it is necessary to resend the LP WUS to the terminal. For another example, if the network device does not receive feedback information or uplink data from the terminal after the maximum delay of the data scheduling, it is necessary to resend the LP WUS to the terminal at the nearest LP WUS listening opportunity.

[0167] In this embodiment, the network device sends an LP WUS to the terminal to wake up the terminal. After receiving the LP WUS, the terminal can send a first message on a first transmission resource, and then the terminal can feedback a response message on a specific transmission resource, so that the network device knows that the terminal has been awakened or the sleep state of the MR has changed, which facilitates timely scheduling of the terminal.
