The method for determining moment information comprises: determining a first moment on the basis of configuration information, wherein the first moment is an end moment of a terminal monitoring a low-power wake-up signal (LP WUS); receiving the LP WUS; and determining a wake-up moment of the terminal on the basis of the first moment. In the method, an end moment of monitoring an LP WUS can be accurately determined, such that missing information detection of a terminal due to a network device sending information to the terminal before the terminal is awakened can be avoided, and it can also be ensured that the network device can send information to the terminal at the earliest possible moment after the terminal is awakened, thereby improving the efficiency of data transmission.

Description

Method, device, equipment and storage medium for determining time information Technical Field

[0001] The present disclosure relates to the field of wireless communication technologies, and in particular to a method, apparatus, device, and storage medium for determining time information. Background Art

[0002] In order to save the power consumption of the terminal, a master transceiver (MR) and a low power wake up receiver (LP WUR, LR for short) are configured in the terminal. The terminal can put the master transceiver into a sleep state or a normal state. When the MR is in a normal state, the terminal uses the MR to process downlink service data and uplink service data. The terminal uses the LP WUR to monitor the low power wake up signal (LP WUS). If the LP WUS is received, the MR is woken up. If the LP WUS is not received or the received LP WUS indicates not to wake up, the MR is kept in a sleep state. By using the LP WUR, the power consumption caused by the MR being turned on for a long time can be reduced, saving the energy consumption of the terminal.

[0038] receiving the LP WUS;

[0039] Determine a wake-up time of the terminal according to the first time.

[0040] In the above embodiment, the end time of monitoring LP WUS can be accurately determined, so that the network device can avoid sending information to the terminal before the terminal wakes up, which may cause information leakage of the terminal, and ensure that the network device can send information to the terminal as soon as possible after the terminal wakes up to improve data transmission efficiency.

[0041] In combination with some embodiments of the first aspect, in some embodiments, the LP WUS includes first wake-up information and second wake-up information, the first wake-up information is wake-up information modulated in a first modulation manner, and the second wake-up information is wake-up information modulated in a second modulation manner.

[0042] In the above embodiment, the LP WUS includes two wake-up messages modulated in different modulation modes, so that both a terminal supporting the first modulation mode and a terminal supporting the second modulation mode can receive and analyze the LP WUS.

[0043] In combination with some embodiments of the first aspect, in some embodiments, the terminal is a terminal that supports the second modulation mode.

[0044] In combination with some embodiments of the first aspect, in some embodiments, the first time is an offset relative to a start time of the LP WUS.

These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the embodiments of the present disclosure, the first indication information may also be referred to as the second indication information, and similarly, the second indication information may also be referred to as the first indication information. Depending on the context, the words "if" and "if" as used herein may be interpreted as "at the time of" or "when" or "in response to"

[0112] The embodiments of the present disclosure are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, and should not be understood as limiting the present disclosure.

[0113] As shown in Figure 1A, the method provided in the embodiment of the present disclosure can be applied to a wireless communication system 100, which may include a terminal 101 and a network device 102. It should be noted that the wireless communication system 100 may also include other devices, and this application does not limit the devices included in the wireless communication system 100.

[0114] It should be understood that the above wireless communication system 100 is applicable to both low-frequency scenarios and high-frequency scenarios. Application scenarios of the wireless communication system 100 include, but are not limited to, long-term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, worldwide interoperability for micro wave access (WiMAX) communication systems, cloud radio access networks (CRAN) systems, future fifth-generation (5G) systems, new radio (NR) communication systems, or future evolved public land mobile networks (PLMN) systems, Internet of Things systems, etc.

[0115] The terminal 101 shown above may be a terminal, an access terminal, a terminal unit, a terminal station, a mobile station (MS), a remote station, a remote terminal, a mobile terminal, a wireless communication device, a terminal agent, an Internet of Things terminal, etc. The terminal 101 may have wireless transceiver capabilities, and may be capable of communicating (e.g., wirelessly communicating) with one or more network devices of one or more communication systems and receiving network services provided by the network devices, where the network devices include but are not limited to the illustrated network device 102.

[0116] Among them, the terminal 101 can be a cellular phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA) device, a handheld device with wireless communication function, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal in a future 5G network, or a terminal in a future evolved PLMN network, etc.

[0117] In the disclosed embodiment, to properly detect the LP WUS, terminal 101 needs to obtain the time domain location and frequency domain location of the LP WUS transmitted by network device 102. Terminal 101 can achieve time and frequency domain synchronization by detecting a synchronization signal. Optionally, the synchronization signal can be a synchronization signal block (SSB) or a low-power synchronization signal (LP-SS). Based on the time and frequency synchronization achieved by the SSB and / or LP-SS, the LP WUS can directly carry wake-up-related information.

[0118] The disclosed embodiments may use different modulation schemes to modulate the LP WUS. For example, Amplitude Shift Keying (ASK) may be used to modulate the wake-up information. Alternatively, On-and-off Keying (OOK) modulation is a type of ASK modulation.

[0119] In one example, when OOK is used to modulate the wake-up information, a high level (OOK ON) is used to represent bit 1 on each OOK symbol, and a low level (OOK OFF) is used to represent bit 0. The time domain sequence or frequency domain sequence carried by each OOK symbol of LP WUS can carry the wake-up information. On each OOK symbol, multiple bits of information can be represented by carrying different sequences. For example, if there are M optional sequences for carrying information on each OOK symbol, then theoretically, M types of information can be carried on the symbol. If it corresponds to the number of bits, it can carry floor(log2M) bits. It can be understood that when M is greater than 2, the information that can be carried by using a time domain sequence or a frequency domain sequence on the OOK symbol is more than the information that can be carried by using OOK amplitude modulation.

[0120] In the embodiment of the present disclosure, the first type of terminal is a terminal supporting the first type of LR, that is, a terminal supporting OOK LR, and the OOK LR can detect the envelope of the OOK symbol of the LP WUS.

[0121] For OOK modulation, the LP WUS may be first encoded (e.g., Manchester encoding) to obtain multiple bits, and then the multiple bits are sequentially mapped to OOK symbols. The duration of the LP WUS is marked as a first length D. The first length D may be predefined, semi-statically configured, or dynamically indicated.

[0122] When OOK LR is used to receive LP WUS, the LP WUS can be obtained only after all OOK symbols within the first duration D are received.

[0123] In the disclosed embodiments, the second type of terminal is a terminal that supports the second type of LR, namely, a terminal that supports OFDM LR. The OFDM LR can detect the time domain sequence or frequency domain sequence carried by the OOK symbols of the LP WUS. OFDM LR detection has better link performance than OOK LR detection.

[0124] For OFDM modulation, a second length d0 of the leading portion of the LP-WUS carries the complete LP-WUS information, where the second length d0 is less than the first length D. When receiving the LP-WUS using OFDM LR, the complete LP-WUS can be obtained by receiving only the leading portion of the LP-WUS by detecting the time domain sequence or frequency domain sequence carried by the OOK symbols. The second length d0 can be predefined, semi-statically configured, or dynamically indicated.

[0125] When OFDM LR receives LP WUS, it can obtain complete LP-WUS information in advance, so as to start waking up MR in advance.

[0126] In the embodiment of the present disclosure, a method of receiving an LP WUS using OOK LR and a method of receiving an LP WUS using OFDM LR are explained with reference to FIG. 1B , 1C, and 1D .

[0127] The complete LP WUS is marked as W. For OOK modulation, all OOK symbols within the first length D carry the complete LP WUS. For OFDM modulation, the first length D may include N time segments of the second length d0. In addition to these N time segments, other segments may also carry complete LP-WUS information.

[0128] The duration corresponding to the LP WUS information is the first length D.

[0129] As shown in Figure 1B , for OOK modulation, all OOK symbols within a first length, D, carry the complete LP WUS. The first length, D, includes a second length, d0, and a third length, d1. The information within the second length, d0, is represented by A, and the information within the third length, d1, is represented by WA. Together, the information within the second length, d0, and the third length, d1, constitute the complete LP WUS, or W.

[0130] As shown in Figure 1B , for OFDM modulation, the first length D includes a second length d0 and a third length d1. The information within the second length d0 represents the complete LP WUS, or W, and the information within the third length d1 represents the complete LP WUS, or W. The second-category terminal only needs to receive the information within the second length d0 to obtain the complete LP WUS. The end time for the OFDM LR in the second-category terminal to monitor the LP WUS can be the end time of one second length d0.

[0131] As shown in FIG. 1C , the OOK modulation method is the same as that in FIG. 1B .

[0132] As shown in Figure 1C, for the OFDM modulation method, the first length D includes three second lengths d0 and one third length d2. The information within the second length d0 represents the complete LP WUS, i.e., W, and the information within the third length d2 represents the complete LP WUS, i.e., W. A second-category terminal only needs to receive information within one second length d0 to obtain the complete LP WUS. When the channel status of the terminal is poor, the terminal can repeatedly receive information within the time period of the second length d0. The end time of the OFDM LR monitoring of the LP WUS by the second-category terminal can be the end time of the second second length d0 or the end time of the third second length d0.

[0133] As shown in Figure 1D, for the OOK modulation scheme, all OOK symbols within the first length D carry the complete LP WUS. The first length D includes three second lengths d0 and one fourth length d3. The information within the first second length d0 is represented as A, the information within the second second length d0 is represented as B, the information within the third second length d0 is represented as C, and the information within the fourth length d3 is represented as WABC. The three second lengths d0 and the information within the fourth length d3 together constitute the complete LP WUS, namely W.

[0134] As shown in Figure 1D, for OFDM modulation, when channel conditions are poor, the first length D includes three second lengths d0 and one fourth length d3. The information within the first second length d0 is represented as WA, the information within the second second length d0 is represented as WB, the information within the third second length d0 is represented as WC, and the information within the fourth length d3 is represented as A+B+C. The three second lengths d0 and the information within the fourth length d3 together constitute the complete LP WUS, or W. The OFDM LR in the second category of terminals ends monitoring the LP WUS.

[0135] In the embodiment of the present disclosure, when the terminal receives an LP WUS and the LP WUS indicates wake-up, the terminal will wake up and monitor the corresponding downlink channel. For example, when the terminal is in the RRC idle state (idle) or the RRC inactive state (inactive), it monitors the paging occasion (PO); for example, when the terminal is in the RRC connected state (connected), it monitors the physical downlink control channel (PDCCH). Because the end time of monitoring LPWUS by the OOK LR in the first type of terminal and the OFDM LR in the second type of terminal may be different. When the wake-up delay (the preparation time of the software and hardware for waking up the UE MR) is set, the wake-up time of the terminal depends on the end time of the terminal monitoring LP WUS. For example, if the duration of the wake-up delay is T, and the end time of the terminal monitoring LP WUS is T0, the wake-up time of the terminal can be determined to be T0+T.

[0136] In the embodiment of the present disclosure, for a terminal in an RRC connected state, since the MR of the terminal can provide feedback of channel state information (CSI) to the network device, the network device can clearly know the quality of the downlink channel corresponding to the MR. If the frequency at which the LR of the terminal monitors the LP WUS is close to the frequency at which the MR monitors the PDCCH, the quality of the channel where the LP WUS is located can be inferred by the quality of the PDCCH. Thus, the network device can configure the end time of monitoring the LP WUS for the second type of terminal. When the channel quality is good, the end time is the end position of the first second time period d0 in Figure 1B, and when the channel quality is poor, the end time is the end position of the second second time period d0 in Figure 1B.

[0137] If the frequency at which the terminal's LR monitors the LP WUS is far from the frequency at which the MR monitors the PDCCH, the quality of the channel where the LP WUS is located cannot be accurately inferred from the PDCCH quality. In this case, the network equipment does not know the channel quality of the channel where the LP WUS is located. Furthermore, for terminals in the RRC idle or RRC inactive state, since there is no connection between the terminal and the base station, the terminal cannot report channel quality, and the network equipment cannot know which terminals are covered or the channel quality of the channel where the LP WUS is located.

[0138] The present disclosure provides a method for determining time information. FIG2A is a schematic diagram of an interaction for determining time information according to an embodiment of the present disclosure, as shown in FIG2A , including the following steps:

[0139] Step S2101: The network device sends configuration information to at least one terminal.

[0140] In some embodiments, configuration information is used to determine the first time instant.

[0141] In some embodiments, the first time is the end time of the terminal monitoring the low power consumption wake-up signal LP WUS.

[0142] In one example, the terminal is a second type terminal, and the first moment is the end moment of the first second time period d0 in FIG1C , that is, the terminal has learned the complete information of the LP WUS at this moment and stops monitoring the LP WUS.

[0143] In some embodiments, the first time is an end time of an LP WUS for the terminal.
