Description

TECHNICAL FIELD

[0001] Embodiments of the present application relate to the technical field of computer, and in particular, to a paging indication receiving method, device and equipment. BACKGROUND

[0002] On the basis of historical technical means, 5G New Radio (NR) can support Discontinuous Reception (DRX) technology, that is, a terminal device can periodically receive a paging at certain specific positions to save the power consumption of the terminal device.

[0003] At present, a Paging Early Indicator (PEI) is introduced in the R17 version specification, which can further reduce the power consumption problem in the paging process by introducing the PEI before receiving a Paging Occasion (PO). That is, in a paging cycle, if the terminal device detects that there is no PEI, or the terminal device detects that there is a PEI but the PEI indicates not to receive the PO, the terminal device directly enters the sleep state again; if the terminal device detects that there is a PEI and the PEI indicates that there is a PO, the terminal device receives the PO at the corresponding position.

[0004] In the related art, in order to enable the terminal device to correctly receive the PO, a Synchronization Signal Block (SSB) before the PEI can be used to perform time / frequency synchronization processing, etc. However, in the above process, in order to demodulate the PEI, it is necessary to wake up at the SSB position, and when the distance between the PEI and the SSB is far, the terminal device may wake up too early, thereby causing unnecessary power consumption.

[0086] The specific embodiments of the present application have been shown through the above-described drawings, and will be described in more detail hereinafter. These drawings and the written description are not intended to restrict the scope of the present application by any means, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0087] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The following description is made with reference to the accompanying drawings in which like reference numerals refer to like elements, and the terminology used is for the purpose of describing particular embodiments only and is not intended to be limiting. The following description is not intended to limit the scope of the present application, but to explain the concepts of the present application.

[0088] It should be noted that, in this document, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements, but can also include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the statement "comprising a" does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes the element.

[0089] When DRX is supported, paging can enable the network to find terminal devices in a radio resource control idle state (RRC-IDLE) and a radio resource control inactive state (RRC-INACTIVE), and can enable the network to notify terminal devices in the RRC-IDLE state and the RRC-INACTIVE state to update through paging when a system message changes, so as to achieve the purpose of synchronizing terminal devices and the network related information. In a DRX cycle, terminal devices in the RRC-IDLE state and the RRC-INACTIVE state only listen to POs associated with themselves.

[0090] The process of the terminal device listening to the PO will be described below. Figure 1A and Figure 1B The process of the terminal device listening to the PO will be described below.

[0091] Figure 1A The process of the terminal device listening to the PO in the prior art is shown in the figure. Please refer to Figure 1A In each DRX cycle, terminal devices in the RRC-IDLE state and the RRC-INACTIVE state can periodically listen to POs associated with themselves.

[0092] In order to further save the power consumption of the terminal device, a PEI wake-up signal can be introduced before the PO is received to inform the terminal device whether the PO needs to be received.

[0093] Figure 1B The process of the terminal device listening to the PO by introducing the PEI in the prior art is shown in the figure. Please refer to Figure 1B Assuming that PO2 is a PO that the terminal device needs to listen to, a PEI can be introduced before PO2, which can be used to indicate whether the terminal device receives PO2.

[0094] Optionally, the time-frequency synchronization problem before the PEI is received can be solved by an SSB associated with the PEI.

[0095] Figure 1C The time-domain position relationship between an SSB and a PEI when the paging indication is received in the prior art is shown in the figure. Please refer to Figure 1C The time-domain position of the SSB is located before the time-domain position of the PEI. Before the PEI is received, in order to solve the time-frequency synchronization problem of the terminal device after it wakes up from sleep, the terminal device is usually woken up at the time-domain position of the SSB. However, when the time-domain position of the SSB and the time-domain position of the PEI are far apart, the terminal device will wake up too early, thereby causing the terminal device to produce additional power consumption.

[0096] Figure 1D FIG. 1 is a schematic diagram of a time domain position relationship between an SSB and a PEI according to an embodiment of the present application. Please refer to FIG. 1. Figure 1D In the case that there is an SSB in the time slot where the PEI is located, and the time domain position of the SSB is after the time domain position of the PEI, the terminal device can be woken up at the time domain position of the PEI, and the PEI can be demodulated and processed through the SSB after the time domain position of the PEI to receive the PEI.

[0097] In the related art, in order to enable the terminal device to correctly receive the PO, the SSB before the PEI can be used to perform time / frequency synchronization processing in advance. However, in the above process, in order to demodulate the PEI, the terminal device needs to wake up at the position of the SSB, and when the distance between the PEI and the SSB is far, the terminal device may wake up too early, thereby causing unnecessary power consumption.

[0098] In the embodiments of the present application, different wake-up positions can be determined by subdividing the position relationship between the PEI and the SSB. In the case that the PEI and the SSB are in the same time slot, and the SSB is after the PEI, the terminal device can be woken up at the first time domain position corresponding to the PEI, and does not need to wake up at the time domain position corresponding to the SSB before the PEI, so as to avoid the terminal from waking up too early, thereby saving the power consumption of the terminal.

[0099] In the following, the method shown in the present application is described through specific embodiments. It should be noted that the following embodiments can exist independently, or can be combined with each other. For the same or similar content, the description is not repeated in different embodiments.

[0100] Figure 2 FIG. 2 is a flowchart of a method for receiving a paging indication according to an embodiment of the present application. Please refer to FIG. 2. Figure 2 The method can include the following steps.

[0101] S201, a first time domain position of a paging indication PEI to be received is determined.

[0102] The execution subject of the embodiments of the present application can be a terminal device, or a chip, a chip module or a paging indication receiving apparatus provided in the terminal device. The paging indication receiving apparatus can be implemented by software, or by the combination of software and hardware. For example, the terminal device can be a mobile phone terminal, an Internet of Things terminal, a wearable device, etc.

[0103] Optionally, the terminal device can determine the first time domain position by the following manner: obtaining a radio resource control (RRC) message; obtaining historical associated beam index information; and determining the first time domain position according to the RRC message and the historical associated beam index information.

[0104] Optionally, the historical association beam index message can be acquired according to the historical receiving process of the terminal device.

[0105] Next, the first time domain position of a PEI provided by an embodiment of the present application is described. Figure 3 The first time domain position of a PEI provided by an embodiment of the present application is described.

[0106] Figure 3 The first time domain position of a PEI provided by an embodiment of the present application is described. Please refer to Figure 3 When the period is 5 slots, the offset is 0, and the duration is 2 slots, it can be seen that the first time domain position of the PEI is located on slot0 and slot1.

[0107] Next, the symbol position occupied by the PEI in a slot is described by taking slot0 as an example. The starting symbol position of the PEI can be indicated by monitoringSymbolsWithinSlot. For example, in Figure 3 In the embodiment, the starting symbol position of the PEI indicated by monitoringSymbolsWithinSlot is located on symbol0 and symbol7 of slot0.

[0108] S202, if there is a first synchronization signal block SSB in the slot where the PEI is located, the terminal device is woken up at the first time domain position.

[0109] The second time domain position of the first SSB is located after the first time domain position.

[0110] Optionally, if there is no first synchronization signal block SSB in the slot where the PEI is located, the terminal device is woken up in the wake-up manner in the prior art, that is, the terminal device is woken up at the time domain position corresponding to the SSB before the PEI.

[0111] In 5G NR, the period of SSB can be configured as 5ms, 10ms, 20ms, 40ms, 80ms and 160ms. And there are relatively fixed several positions in the occupation of time domain symbols. Next, the time domain position of SSB is described. Figure 4A - Figure 4B The time domain position of SSB is described.

[0112] Figure 4A The time domain position of SSB provided by an embodiment of the present application is described. Please refer to Figure 4AEach half-frame consists of 5 subframes with a length of 1ms. When the subcarrier spacing is 15kHz, if the carrier frequency is less than or equal to 3GHz, the SSB is located on subframes 0 and 1 of the half-frame, and a maximum of 4 SSBs (L=4) can be transmitted in each half-frame; if the carrier frequency is within the first frequency range (FR1) and greater than 3GHz, the SSB is located on subframes 0 to 3 of the half-frame, and a maximum of 8 SSBs (L=8) can be transmitted in each half-frame.

[0113] Figure 4B This is a schematic diagram illustrating the time-domain location of an SSB provided in an embodiment of this application. Please refer to... Figure 4B When the subcarrier spacing is 15kHz and the carrier frequency is less than or equal to 3GHz, each subframe can consist of one slot, and each slot can consist of 14 OFDM symbols. Therefore, one subframe can correspond to 14 OFDM symbols. Below, we will use subframe 0 as an example to illustrate the OFDM symbol positions occupied by the SSB in one slot. Figure 4B As can be seen, the first symbol of the SSB can be located on OFDM symbol 2 and OFDM symbol 8 in subframe 0.

[0114] Below, in conjunction with Figure 5 The situation where PEI and the first SSB co-slot is explained.

[0115] Figure 5 This is a schematic diagram illustrating one possible location of the PEI and the first SSB co-slot provided in an embodiment of this application. Please refer to... Figure 5 For example, in any slot, PEI is located on symbols 0 and 1, and SSB is located on symbols 2 to 5. In this way, PEI and SSB are in the same time slot and can be completely separated in the time domain.

[0116] The paging indication receiving method provided in this application embodiment can determine the first time-domain position of the PEI to be received; if a first SSB exists in the time slot where the PEI is located, the terminal device is woken up at the first time-domain position, and the second time-domain position of the first SSB is located after the first time-domain position. In the above process, different wake-up positions can be determined by subdividing the positional relationship between the PEI and the SSB. When the PEI and the SSB share a time slot, and the SSB is located after the PEI, the terminal can be woken up at the first time-domain position corresponding to the PEI, without having to wake up at the time-domain position corresponding to the SSB before the PEI, thus avoiding premature wake-up of the terminal and saving terminal power consumption.

[0117] Figure 6 This is a flowchart illustrating a method for receiving a paging indication provided in an embodiment of this application. Please refer to...Figure 6 The method can comprise:

[0118] S601, acquiring an RRC message.

[0119] S602, acquiring historical associated beam index information.

[0120] It should be noted that the specific execution process of S601-S602 can refer to the execution process of S201, which will not be repeated here.

[0121] S603, determining a first time domain position according to the RRC message and the historical associated beam index information.

[0122] Optionally, the first time domain position can be determined by: performing parsing processing on the RRC message to obtain search space information; determining a PEI starting symbol position in the search space information according to the historical associated beam index information; and determining the first time domain position according to the search space information and the PEI starting symbol position.

[0123] The search space information can be used to indicate the time domain period and offset of the PEI on the search space (SearchSpace), the number of slots continuously monitored in each period, and the specific starting symbol monitored in each slot.

[0124] Optionally, according to the standard definition, the distance between the first time domain position where the PEI is located and the time domain position where the PO is located can be in the range of {0, 1, …, 16} paging frames (PF), and can be in the same PF or can be spaced by 16 PFs. The starting symbol position of the PEI on the search space can be further determined by the symbol position indication.

[0125] S604, acquiring MIB message and SIB message.

[0126] Optionally, a Master Information Block (MIB) message can be acquired by monitoring a Physical Broadcast Channel (PBCH). After acquiring the MIB message, configuration information can be obtained by parsing the MIB message by the terminal device. According to the configuration information, a Physical Downlink Control Channel (PDCCH) and a Physical Downlink Shared Channel (PDSCH) are further parsed to obtain a System Information Block (SIB) message and other related RRC messages. By parsing the SIB message and other related RRC messages, PEI information, DRX information, frame offset information, symbol offset information, search space information, and the like are further obtained.

[0127] S605. Determine a plurality of candidate time domain positions according to the MIB message and the SIB message.

[0128] Optionally, the plurality of candidate time domain positions can be determined by: parsing the MIB message and the SIB message to obtain subcarrier spacing information, SSB type, time domain position information and periodicity information of the SSB; and determining the plurality of candidate time domain positions according to the subcarrier spacing information, the SSB type, the time domain position information and the periodicity information of the SSB.

[0129] S606. Determine a first candidate time domain position from the plurality of candidate time domain positions according to the first time domain position.

[0130] The first candidate time domain position is located after the first time domain position and is closest to the first time domain position.

[0131] For example, in the case of Figure 5 , the first time domain position is located on symbol 0 and symbol 1 in slot 0, the candidate time domain position 1 is located on symbol 2-symbol 5 in slot 0, and the candidate time domain position 2 is located on symbol 2-symbol 5 in slot 1. At this time, the candidate time domain position 1 is closest to the first time domain position, and then the candidate time domain position 1 is determined as the first candidate time domain position.

[0132] S607. Determine whether the first time domain position and the first candidate time domain position are located in the same slot.

[0133] If yes, perform S608-S612;

[0134] If no, perform S613-S614.

[0135] S608, determine that the first SSB exists in the time slot where the PEI is located.

[0136] For example, in the case of Figure 5 , the first time domain position is located on symbol0 and symbol1 in slot0, and the first candidate time domain position is located on symbol2-symbol5 after symbol1, at this time, the first time domain position and the first candidate time domain position are both located in slot0, then it is determined that the first SSB exists in the time slot where the PEI is located.

[0137] S609, wake up the terminal device at the first time domain position.

[0138] Optionally, after determining that the PEI and the SSB are in the same time slot, the terminal device can first perform a sleep process, and then wake up the terminal device at the first time domain position to perform a PEI receiving process.

[0139] Optionally, after waking up the terminal device, the entire burst data needs to be dumped in the SSB burst, and automatic gain control (AGC), beam selection, time-frequency offset estimation and other processes are performed in the dumping process.

[0140] Next, the PEI receiving process is described in combination with S610-S612.

[0141] S610, capture monitoring data.

[0142] Optionally, the monitoring data includes PEI data and SSB data. When the PEI receiving method provided in the embodiments of the present application is executed, the terminal device needs to dump the monitoring data first, so as to subsequently demodulate and process the PEI data through the SSB data.

[0143] S611, analyze the SSB data, perform time-frequency offset estimation processing, and determine a time-frequency offset estimation amount according to the first SSB.

[0144] S612, process the PEI according to the time-frequency offset estimation amount.

[0145] Optionally, the PEI data can be demodulated and processed according to the time-frequency offset estimation amount, and the PEI is received after the demodulation and processing is completed.

[0146] S613, determine that the first SSB does not exist in the time slot where the PEI is located.

[0147] For example, in the case of Figure 5In this case, the first time domain position is located on symbol 0 and symbol 1 in slot 0, and the first candidate time domain position is located on symbol 2-symbol 5 in slot 1. In this case, the first time domain position and the first candidate time domain position are not in the same slot. Then, it is indicated that the first SSB does not exist in the time slot where the PEI is located.

[0148] S614, wake up the terminal device at the time domain position corresponding to the SSB before the PEI.

[0149] Optionally, after waking up the terminal device, the synchronization processing such as AGC, beam selection, and time-frequency offset estimation can be performed according to the SSB before the PEI, and after the synchronization processing is completed, the PEI is received.

[0150] The method for receiving a paging indication provided by the embodiments of the present application can determine the first time domain position of the PEI to be received. If the first SSB exists in the time slot where the PEI is located, the terminal device is woken up at the first time domain position. The second time domain position of the first SSB is located after the first time domain position. In the above process, different wake-up positions can be determined by subdividing the positional relationship between the PEI and the SSB. When the PEI and the SSB are in the same time slot, and the SSB is located after the PEI, the terminal can be woken up at the first time domain position corresponding to the PEI, without waking up at the time domain position corresponding to the SSB before the PEI, so as to avoid the terminal from waking up too early, thereby saving the terminal power consumption.

[0151] Figure 7 A structural diagram of the paging indication receiving device provided by the embodiments of the present application is provided. The paging indication receiving device can be a chip or a chip module. Please refer to Figure 7 The paging indication receiving device 10 includes a first determination module 11 and a wake-up module 12, wherein,

[0152] The first determination module 11 is configured to determine the first time domain position of the PEI to be received.
