Description

Wireless communication methods, terminal devices, and network devices Technical Field

[0001] This application relates to the field of communication technology, and more specifically, to a wireless communication method, terminal device, and network device. Background Technology

[0002] Some communication technologies introduce a first receiver (e.g., a low-power-wake-up receiver (LP-WUR)) into the terminal device. While the first receiver is listening for a first signal (e.g., a low-power-wake-up signal (LP-WUS)), a second receiver (e.g., a main receiver (MR)) can be in a low-power state. The first signal can be used to wake up the second receiver. For example, upon receiving the first signal, the first receiver can wake up the second receiver. Because the second receiver can be in a low-power state, this scheme can save energy consumption in the second receiver.

For example, cellular phones and cars communicate with each other using sidelink signals. Cellular phones and smart home devices communicate without relaying communication signals through a base station.

[0041] The network device in this application embodiment can be a device for communicating with terminal devices. The network device may also include an access network device. The access network device can provide communication coverage for a specific geographical area and can communicate with the terminal device 120 located within that coverage area. The access network device can also be called a wireless access network device or a base station, etc. In this application embodiment, the access network device can refer to a radio access network (RAN) node (or device) that connects the terminal device to the wireless network.

[0042] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0043] Wireless communication systems involve communication equipment that can include not only access network equipment and terminal equipment, but also core network elements. Core network elements can be implemented through devices; that is, core network elements are core network devices. It can be understood that core network devices can also be a type of network device.

[0044] The core network elements in this embodiment may include network elements that process and forward user signaling and data. For example, core network equipment may include core access and mobility management functions (AMF), session management functions (SMF), user plane gateways, location management functions (LMF), and other core network equipment. The user plane gateway may be a server with functions such as mobility management, routing, and forwarding of user plane data, generally located on the network side, such as a serving gateway (SGW), packet data network gateway (PGW), or user plane function (UPF). Of course, the core network may also include other network elements, which are not listed here.

[0046] Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminal devices are located.

[0047] It should be understood that all or part of the functions of the communication device in this application can also be implemented by software functions running on hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform).

[0048] Discontinuous reception (DRX)

[0049] To reduce terminal power consumption, some communication systems (such as LTE and NR systems) have proposed the DRX mechanism. The DRX mechanism allows the terminal to enter a discontinuous reception state when there is no data reception, rather than continuously keeping the receiver on, thus saving power. The DRX mechanism involves configuring a DRX cycle for the terminal. A DRX cycle consists of an "on-duration" period and an "opportunity for DRX." During the on-duration period, the terminal listens for and receives downlink channels and signals, including the PDCCH. During the off-duration period, the terminal does not receive downlink channels and signals such as the PDCCH to reduce power consumption.

[0050] The evolution of communication systems has placed higher demands on terminal energy efficiency. For some DRX mechanisms, during each activation period, the terminal needs to continuously monitor the PDCCH to determine whether the network device will schedule data for it. However, for most terminals, there may be no need to receive data transmission for extended periods, yet they still need to periodically wake up to listen for potential downlink transmissions. There is room for further optimization in energy-saving methods for these types of terminals.

[0051] To address the aforementioned issues, some communication standards (such as 3GPP R16) have introduced power-saving signals. These signals enable further energy conservation for terminal devices in Radio Resource Control (RRC) connected state (RRC_CONNECTED). Power-saving signals can be used in conjunction with the DRX mechanism. For example, before entering the DRX active period, the terminal can determine whether it needs to receive data during the DRX active period based on the power-saving signal's indication. When the terminal has data transmission in a DRX cycle, the power-saving signal "wakes up" the terminal, and accordingly, the terminal listens to the PDCCH during the DRX active period. Conversely, when the terminal has no data transmission in a DRX cycle, the power-saving signal does not "wake up" the terminal, and accordingly, the terminal does not need to listen to the PDCCH during the DRX active period. This DRX mechanism combined with power-saving signals ensures that if the power-saving signal does not wake up the terminal during a DRX cycle, the terminal does not need to listen to the PDCCH even if it is in the DRX active period, thus achieving energy conservation.

[0052] Some communication standards (such as 3GPP R17) have further established terminal power saving enhancement projects. These projects further standardize power saving for terminals in RRC_IDLE and RRC_INACTIVE states. The power consumption of terminals in RRC_IDLE and RRC_INACTIVE states primarily stems from periodic, discontinuous paging reception, including time-frequency synchronization recovery and automatic gain control (AGC) before the arrival of the PO (Position Request), and power consumption from detecting the paging PDCCH during the PO.

[0053] To reduce power consumption during paging reception, relevant standards have introduced a power-saving signal for paging reception. This power-saving signal can be called PEI. PEI can be used to indicate whether the terminal needs to receive a paging message at the PO before the PO arrives. In other words, PEI can be used to indicate whether to "wake up" the terminal before the PO arrives.

[0054] PEI

[0055] The following example uses the PEI design in the 3GPP R17 standard to illustrate the technologies related to PEI.

[0056] PEI listening occasion (PEI-O)

[0057] PEI-O is a collection of listening opportunities for multiple physical downlink control channels (PDCCH).

[0058] In some embodiments, when nrofPDCCH-MonitoringOccasionPerSSB-InPO is not configured, PEI-O can be a set of S consecutive PDCCH monitoring opportunities. Here, S is the actual number of transmitted SSBs determined by ssb-PositionsInBurst in system information broadcast 1 (SIB1). In PEI-O, the quasi-colocation (QCL) of the Kth PEI PDCCH monitoring opportunity can be the same as the Kth PDCCH monitoring opportunity paging in the PO (the QCL is referenced to the SSB).

[0059] In unlicensed spectrum, PEI-O can be a set of (S*X) consecutive PDCCH monitoring opportunities. Here, S is the actual number of transmitted SSBs determined by ssb-PositionsInBurst in SIB1. If nrofPDCCH-MonitoringOccasionPerSSB-InPO is configured, X takes this configured value; otherwise, X = 1. The (x*S+K)th PDCCH monitoring opportunity in the PEI monitoring opportunity corresponds to the Kth transmitted SSB, where x = 0, 1, ..., X-1, K = 1, 2, ..., S. If X > 1, when the terminal detects a PEI in a PEI monitoring opportunity, the terminal does not need to continue monitoring subsequent monitoring opportunities associated with that PEI monitoring opportunity.

[0060] Mapping between PEI and PO

[0061] Network devices can configure multiple Points of Interest (POs) for each paging frame (PF). On the one hand, if each PEI corresponds to one PO, there will be a large number of independent PEIs, which will increase PEI overhead. On the other hand, if each PEI corresponds to one PO, the PEIs corresponding to these POs may overlap in the time domain. In the 3GPP R15 / 16 standard, a wake-up signal (WUS) can be associated with one or more POs. During PEI design, to reduce PEI overhead and avoid PEI overlap, a mapping mechanism similar to that of WUS in the 3GPP R15 / 16 standard was ultimately determined, i.e., one PEI can be associated with one or more POs.

[0062] In some embodiments, one PEI can be associated with POnumPerPEI POs. As shown in Figure 2, POnumPerPEI can be 4. That is, in Figure 2, one PEI can be associated with 4 POs.

[0063] Optionally, the POnumPerPEI associated with a PEI can be in one or more PFs, and the maximum number of PFs associated with a PEI is 2.

[0064] Optionally, POnumPerPEI is N×N s The factor. Where N can be the number of paging frames in one paging cycle, N s This can be the number of POs in a paging frame. POnumPerPEI can be configured via SIB, with a value range of {1, 2, 4, 8}.

[0065] Location of PEI-O

[0066] The terminal can determine the location of the PO corresponding to the PEI-O based on the reference point and the offset value (from the reference point to the first PDCCH listening time of the PEI-O). The following example, referring to Figure 2, further illustrates this. The location of the PEI-O can be determined through steps 1 and 2.

[0067] Step 1: Determine the reference frame and use the start point of the reference frame as the reference point.

[0068] The reference frame can be determined based on the first PF among all PFs associated with the PEI (in the case of multiple POs associated with a PEI, the associated POs may be located in different PFs) and a frame-level offset value.

[0069] The frame-level offset from the first PF among all PFs associated with the PEI to the reference frame can be configured via SIB.

[0070] Step 2: Based on the reference point and symbol-level offset value, determine the location of the first PDCCH listening opportunity in PEI-O.

[0071] The symbol-level offset from the reference point to the first PDCCH monitoring time in PEI-O can be configured via SIB. For example, the symbol-level offset can be provided by firstPDCCH-MonitoringOccasionOfPEI-O.

[0072] LP-WUS / WUR

[0073] To further enhance energy efficiency in terminals, some research projects (such as 3GPP R18) have introduced LP-WUR and designed corresponding LP-WUS signals. Specifically, when using LP-WUR to listen for wake-up signals, the MR (Mobile Receiver) can be in an extremely low-power state (e.g., ultra-deep sleep), thus achieving overall energy savings for the terminal. LP-WUR can listen for LP-WUS signals, and upon receiving an LP-WUS signal from a network device, it can wake up the main receiver.

[0074] The following explanation uses the 3GPP RAN1 working group's research on LP-WUS / WUR as an example.

[0075] In studying the LP-WUS / WUR, the RAN1 working group reached a preliminary consensus on the accuracy of the LP-WUR oscillator, considering the following four options.

[0076] Option 1: The maximum frequency error of the oscillator is 200ppm, and the frequency drift of the oscillator is 0.1ppm / s.

[0077] Option 2: The maximum frequency error of the oscillator is 50 ppm, and the frequency drift of the oscillator is 0.1 ppm / s.

[0078] Option 3: The maximum frequency error of the oscillator is 10 ppm, and the frequency drift of the oscillator is 0.05 ppm / s.

[0079] Option 4: The maximum frequency error of the oscillator is 5 ppm, and the frequency drift of the oscillator is 0.05 ppm / s.

[0080] Considering that the LP-WUR real-time clock (RTC) has a maximum frequency error of 20ppm and a frequency drift of 0.1ppm / s.

[0081] In 3GPP Release 18, LP-WUS / WUR was studied, resulting in research report TR 38.869. In 3GPP Release 19, LP-WUS / WUR was standardized. The following section introduces some of the standardization content and objectives in Release 19.

[0082] R19 standardizes a universal LP-WUS design (RAN1, RAN4) applicable to both IDLE / INACTIVE and CONNECTED states. The standardization is based on OOK (OOK-1 and / or OOK-4) LP-WUS signals, and orthogonal frequency division multiplexing (OFDM) sequences can be superimposed on the OOK symbols. The LP-WUS design should ensure that, in the IDLE / INACTIVE state, regardless of the receiver design used, the LP-WUS transmits the same information. Simultaneously, the OFDM sequences can also carry information. LP-WUS should at least support duty-cycled listening.

[0083] First, for the IDLE / INACTIVE state, the standardized LP-WUS triggering process and configuration for listening to paging messages should include at least: "Configuration", "Subgroup" and "Conditions for entering / exiting LP-WUS listening" (RAN2, RAN1, RAN3, RAN4).

[0084] Additionally, for the IDLE / INACTIVE state, the LP-SS with a LP-WUR normalization period of Yms can be used for synchronization and / or radio resource management (RRM) measurements (RAN1, RAN4) of the serving cell. The LP-SS can be based on OOK-1 and / or OOK-4 waveforms, and OFDM sequences can be superimposed on the OOK symbols with or without superimposing. In the WI, the choice is made regarding whether to superimpose OFDM sequences on the LP-SS.

[0085] It should be noted that for LP-WURs that can receive the primary synchronization signal (PSS) / secondary synchronization signal (SSS) in related technologies, the PSS / SSS signals in related technologies can be used to replace LP-SS for synchronization and RRM measurement.

[0086] It should be noted that the value of Y needs to be determined during the WI stage. For example, 320m can be used as an initial value for Y.

[0087] Further standardization of RRM relaxation is performed on the measurements of the terminal's main receiver in the serving cell and neighboring cells. The RRM measurement of the terminal equipment's serving cell can be devolved from MR to LP-WUR, including the necessary condition design (RAN4, RAN2).

[0088] Secondly, for the CONNECTED state, it is necessary to standardize the process of the LP-WUS trigger terminal's master receiver listening to the PDCCH, including the activation and deactivation process of LP-WUS (RAN2, RAN1).

[0089] It should be noted that in CONNECTED state, the terminal's main receiver does not enter a deep sleep state, and the terminal's radio resources (RR), radio link monitoring (RLM), bidirectional forwarding detection (BFD), and channel state information (CSI) measurements are performed by the main receiver.

[0090] It should be noted that the coverage performance of LP-WUS and LP-SS is close to that of Physical Uplink Shared Channel (PUSCH) message 3 (msg3).

[0091] SSB

[0092] The following explanation of SSB will use the NR system as an example.

[0093] SSB Structure

[0094] In NR systems, downlink synchronization is achieved by receiving the PSS and SSS signals from the SSB. Figure 3 is an example diagram of an SSB structure.

[0095] In the time domain, one SSB can occupy four OFDM symbols.

[0096] In the frequency domain, one SSB can occupy 20 RBs.

[0097] As shown in Figure 3, the subcarriers are numbered from 0 to 239. The PSS is located on the middle 127 subcarriers (SC) of symbol #0, and the SSS is located on the middle 127 SCs of symbol #2. To protect the PSS and SSS, several carriers are set to 0.

[0098] As shown in Figure 3, in the SSB, the physical broadcast channel (PBCH) can occupy all symbols #1 and #3, plus symbol #2 minus the SSS and guard band. After deducting the demodulation reference symbol (DMRS) on symbols #1 and #3, the remaining 2*(240-60) = 360 subcarriers are used for PBCH transmission. The number of SCs after deducting the DMRS on symbol #2 is (240-127-8-9)*3 / 4 = 72 carriers. Therefore, the PBCH has a total of 432 subcarriers.

[0099] As shown in Figure 3, DMRS is inserted into the PBCH for transmission, and its starting position in the SSB is determined by the physical cell ID modulo 4.

[0100] SSB transmission

[0101] SSB can transmit the same SSB in different directions via beamforming in a TDD manner, so that terminal devices in each direction can receive the SSB. A series of SSBs transmitted by a network device can be called a Synchronous Broadcast Block Burst Set (SS BURST SET).

[0102] Figure 4A illustrates a scenario for transmitting SSBs. As shown in Figure 4A, within a half-frame (5ms) range, the network device transmits eight SSBs with SSB indices #0 to #7 through eight beams to cover different directions. Figure 4A shows that these eight SSBs can form a set of synchronization broadcast blocks.

[0103] The terminal device can receive multiple SSBs with different signal strengths. The terminal device can select the beam corresponding to the SSB with the strongest signal strength as its own SSB beam.

[0104] As shown in Figure 4A, UE1 and UE2 receive eight SSBs with different signal strengths. For the SSBs received by UE1, SSB#1 has the strongest signal strength. Therefore, the beam corresponding to SSB#1 can be used as the SSB beam for UE1. For the SSBs received by UE2, SSB#6 has the strongest signal strength. Therefore, the beam corresponding to SSB#6 can be used as the SSB beam for UE2.

[0105] The period of the synchronous broadcast block set can refer to the time interval at which the synchronous broadcast block set repeats. For example, this period can be set to 20ms by default. In the scenario shown in Figure 4A, the period of the synchronous broadcast block set is 20ms. In the ServingCellConfigCommon information element (IE) of TS38.331, the period value range of SSB (ssb-periodicityServingCell) can be seen as ENUMERATED{ms5, ms10, ms20, ms40, ms80, ms160, spare2, spare1}.

[0106] The time-domain configuration of the SSB within 5ms is shown in Table 1. Table 1 gives the starting OFDM position of the SSB within 5ms.

[0107] Table 1

[0108] Figure 4B is an example of the SSB distribution in Case A when f ≤ 3 GHz. In Figure 4B, the SSB period is 20 ms.

[0109] It is important to note that not all SSBs within the synchronous broadcast block set must be sent.

[0110] Exemplarily, in the ServingCellConfigCommon IE of TS38.331, the index of the actually transmitted SSB is identified by the ssb-PositionsInBurst IE. An example of the ServingCellConfigCommon IE is shown below.

[0111] Among them, shortBitmap, mediumBitmap, and longBitmap can respectively identify the index of the actually transmitted SSB in the cases of f < 3 GHz, 3 GHz < f < 6 GHz, and f > 6 GHz. shortBitmap, mediumBitmap, and longBitmap use the form of a bitmap to identify whether the corresponding SSB index is transmitted. For example, 0 can indicate not transmitted, and 1 can indicate transmitted.

[0112] FIG. 6 is a schematic flowchart of a wireless communication method provided by an embodiment of the present application. The method shown in FIG. 6 can be executed by a terminal device and a network device. The method shown in FIG. 6 can include step S610.

[0113] Step S610, a first receiver of the terminal device listens for a first signal on a first resource.

[0114] The first signal can be used to wake up a second receiver. Exemplarily, the first receiver can determine whether to wake up the second receiver according to the indication of the first signal. For example, in response to the first receiver receiving the first signal, the first receiver can wake up the second receiver. Also, in the case where the first receiver does not receive the first signal, the first receiver can not wake up the second receiver, that is, does not change the working state of the second receiver. Also, in response to the first receiver receiving the first signal and the first signal indicating to wake up the second receiver, the first receiver can wake up the second receiver. Also, in the case where the first receiver receives the first signal and the first signal indicates not to wake up the second receiver, the first receiver can not wake up the second receiver.

[0115] The first signal can be sent to the terminal device or to a terminal device group where the terminal device is located. In other words, the first receiver of the terminal device can receive the first signal sent to the terminal device or the first signal sent to the terminal device group where the terminal device is located, so as to wake up the second receiver based on the first signal.

[0116] The first receiver can continuously listen for the first signal. Or, the first receiver can perform discontinuous listening for the first signal. Discontinuous listening can be performed, for example, in a duty-cycled manner.

[0117] While the first receiver is listening to the first signal, the second receiver can be in a low-power state. A low-power state could be, for example, a deep sleep state. Understandably, in this low-power state, the second receiver can disable or reduce some functions (e.g., not receiving some or all signals), thereby reducing power consumption. When the first receiver wakes the second receiver, the second receiver can resume its operating state. In this operating state, the second receiver can enable or restore some or all functions (e.g., it can receive some or all signals), thus enabling normal communication.

[0118] For example, the first receiver may include a low-power receiver (LR). The LR may be, for example, an LP-WUR. The second receiver may include an MR.

[0119] The first signal may include LP-WUS. See above for a detailed explanation of LP-WUS.

[0120] In some embodiments, the first signal can be modulated using an OOK method. For example, the first signal can be based on OOK-1 and / or OOK-4 waveforms. An OFDM sequence may or may not be superimposed on the OOK symbol.

[0121] Figures 5A and 5B show waveform examples of OOK-1 and OOK-4, respectively, with the first signal including LP-WUS.

[0122] As shown in Figure 5A, in the OOK-1 waveform, each OFDM symbol can transmit 1 bit of information. That is, the time domain length of 1 OFDM can transmit 1 OOK symbol. The sub-carrier (SC) settings of the LP-WUS signal can satisfy: OOK = "1": modulation is performed on all LP-WUS subcarriers to transmit the information of bit "1", and the corresponding symbol can also be called an "OOK-on" symbol; OOK = "0": the power on all LP-WUS subcarriers is set to 0 to transmit the information of bit "0", and the corresponding symbol can also be called an "OOK-off" symbol.

[0123] As shown in Figure 5B, in the OOK-4 waveform, each OFDM symbol transmits M bits of information, meaning that the time-domain length of one OFDM symbol transmits M OOK symbols. Here, M can be a positive integer. For example, in Figure 5B, M can be 4 bits. The value of M can be, for example, 1001.

[0124] In Figure 5B, the N subcarriers of OOK-4 are generated by a transformation (e.g., based on DFT or least squares). N' samples are generated from M bits. Signal modification may or may not be used. Truncation or other additional modifications may or may not be used; if not used, N and N' have the same value, and N' can be the same as K. Here, K can be the total number of subcarriers.

[0125] The first resource can be used to transmit the first signal. In other words, if it is necessary to transmit the first signal, the first signal can be carried on the first resource.

[0126] In some embodiments, the method shown in FIG6 may further include step S620, in which the network device may send a first signal to a first receiver of the terminal device. The first signal is capable of transmission on a first resource.

[0127] It should be noted that this application does not restrict the order in which steps S610 and S620 are performed. For example, steps S610 and S620 can be performed simultaneously.

[0128] Therefore, the first resource may or may not carry the first signal. Consequently, the first receiver of the terminal device may or may not receive the first signal on the first resource.

[0129] The first resource satisfies the first rule. For the terminal device, it can determine the first resource according to the first rule, and thus listen for the first signal on the appropriate resource to accurately receive the first signal sent by the network device. For the network device, it can determine the first resource according to the first rule, and thus send the first signal on the appropriate resource so that the terminal device can accurately receive the first signal.

[0130] In some embodiments, the first rule may be associated with the second resource. For ease of understanding, the second resource will be described first below.

[0131] The first receiver can listen for synchronization signals on the second resource. In other words, the second resource can be used to transmit synchronization signals.

[0132] Optionally, the first receiver of the terminal device can achieve synchronization based on the synchronization signal. Due to the accuracy of the oscillator of the first receiver itself, a time-frequency deviation will occur as the first signal is monitored. Therefore, this time-frequency deviation can be eliminated by monitoring the synchronization signal.

[0133] Alternatively, the terminal device can perform measurements via a synchronization signal. Measurements may include, for example, RRM measurements.

[0134] The first receiver can listen to a synchronization signal before listening to the first signal. For example, after the first receiver can listen to the synchronization signal for synchronization and / or RRM measurements, the first receiver can listen to the first signal. It is understood that after synchronization is achieved by listening to the synchronization signal, the time-frequency deviation can be eliminated, thereby enabling the first receiver to accurately listen to the first signal and thus wake up the second receiver at the appropriate time.

[0135] In some embodiments, the synchronization signal can be modulated using an OOK method. For example, the synchronization signal can be based on OOK-1 and / or OOK-4 waveforms. An OFDM sequence may or may not be superimposed on the OOK symbol.

[0136] In some embodiments, the synchronization signal may include LP-SS. For example, if the first receiver includes LR, the synchronization signal may include LP-SS. A detailed description of LP-SS is provided above.

[0137] In some embodiments, the synchronization signal may include one or more of the following: PSS, SSS, and SSB. The modulation scheme of PSS / SSS differs from that of LP-SS. For example, some high-capacity receivers (LRs) may be capable of listening to one or more of PSS, SSS, and SSB. When the first receiver includes a high-capacity LR, the synchronization signal may include one or more of the following: PSS, SSS, SSB, and LP-SS.

[0138] For example, LRs can have different design configurations. At least two categories of LR receiver designs can exist. Category 1 LRs can only receive LP-SS for synchronization and / or measurement, and do not have reception detection capabilities for one or more of PSS, SSS, and SSB. Category 2 LRs have reception detection capabilities for one or more of PSS, SSS, and SSB, meaning they can perform synchronization and / or measurement by receiving one or more of PSS, SSS, and SSB. When the first receiver includes a Category 1 LR, the synchronization signal listened to by the first receiver may include LP-SS. When the first receiver includes a Category 2 LR, the synchronization signal listened to by the first receiver may include one or more of the following: PSS, SSS, SSB, and LP-SS.

[0139] The first rule relating to the second resource is explained below.

[0140] In some embodiments, the first resource may include a first frequency domain resource. The second resource may include a second frequency domain resource. The first frequency domain resource and the second frequency domain resource may satisfy a first rule. That is, the first rule may be related to the first frequency domain resource and the second frequency domain resource. For example, the second frequency domain resource can be determined based on the first rule and the first frequency domain resource. Similarly, the first frequency domain resource can be determined based on the first rule and the second frequency domain resource.

[0141] As one possible implementation, the first frequency domain resource and the second frequency domain resource can be located in the same set of frequency domain resources.

[0142] For example, the frequency domain resource set may include a bandwidth part (BWP). In this case, the first frequency domain resource and the second frequency domain resource may reside in the same BWP. Alternatively, the frequency domain resource set may include the frequency domain resources actually used by the signal. In this case, the same frequency domain resource set may be a frequency domain resource in the BWP to which the first resource belongs that does not contain a guard interval, or a frequency domain resource actually used by the first signal / synchronization signal in the BWP.

[0143] It should be noted that when the first frequency domain resource and the second frequency domain resource are located in the same frequency domain resource set, this same frequency domain resource set can be configured by the network device. Additionally, this same frequency domain resource set can be a dedicated frequency domain resource set allocated for monitoring the first receiver.

[0144] Figure 7 shows an example diagram of various frequency domain resource sets. In Figure 7, the first signal is LP-WUS, the synchronization signal is LP-SS, and the frequency domain resource set is a downlink (DL) BWP. Both the first and second frequency domain resources can be located in this DL BWP.

[0145] As shown in Figure 7, in (b), the DL BWP may include a candidate frequency domain resource set of LP-WUS.

[0146] As shown in Figure 7, the DL BWP can include one or more candidate frequency domain resource sets of LP-SS. In (c-1) or (c-2), the DL BWP includes one candidate frequency domain resource set of LP-SS. In (c-3), the DL BWP includes three candidate frequency domain resource sets of LP-SS.

[0147] It is understandable that when the first frequency domain resource set and the second frequency domain resource set are located in the same frequency domain resource set, this same frequency domain resource set can be shared by the first signal and the synchronization signal. That is, both the first signal and the synchronization signal can be carried by this same frequency domain resource set.

[0148] Optionally, the aforementioned set of resources in the same frequency domain may include guard intervals. Guard intervals cannot be used to carry the first signal and / or synchronization signal. Alternatively, guard intervals cannot be used to carry any valid signal. Guard intervals can be used to separate the frequency domain resources carrying the first signal and / or synchronization signal from other frequency domain resources. Guard intervals can be distributed on both sides of the set of frequency domain resources. Continuing to refer to Figure 7, as can be seen from Figure 7, the DL BWP may include guard intervals located on both sides.

[0149] Optionally, the aforementioned set of resources in the same frequency domain can be a dedicated frequency domain resource set for OOK modulation. The dedicated frequency domain resource set for OOK modulation may include the OOK modulation bandwidth and guard intervals evenly distributed on both sides.

[0150] In some embodiments, the frequency domain resource set for transmitting the first signal and / or the synchronization signal needs to include guard intervals. For example, when the first signal is modulated by OOK, the BWP for transmitting the first signal needs to include guard intervals. Similarly, when the synchronization signal is modulated by OOK, the BWP for transmitting the synchronization signal needs to include guard intervals. When both the frequency domain resource set for transmitting the first signal and the frequency domain resource set for the synchronization signal need to include guard intervals, the first frequency domain resource corresponding to the first signal and the second frequency domain resource corresponding to the synchronization signal are located in the same frequency domain resource set, which reduces the number of guard intervals required. For example, if the first and second frequency domain resources are located in two different frequency domain resource sets, guard intervals need to be set on both sides of each of these two frequency domain resource sets, resulting in a total of four guard intervals. If the first and second frequency domain resources are located in the same frequency domain resource set, guard intervals only need to be set on both sides of that same frequency domain resource set, thereby reducing the total number of guard intervals, conserving frequency domain resources, and allowing more frequency domain resources to be used for transmitting valid signals.

[0151] Optionally, when the first frequency domain resource and the second frequency domain resource are located in the same set of frequency domain resources, the first rule may include: the size of the first frequency domain resource is the same as the size of the second frequency domain resource, and the position of the first frequency domain resource is the same as the position of the second frequency domain resource. In other words, the first frequency domain resource and the second frequency domain resource are completely identical. That is, the first signal and the synchronization signal use the exact same frequency domain resources. Continuing to refer to Figure 7, the second frequency domain resource shown in (c-2) (the frequency domain resource carrying LP-SS) and the first frequency domain resource shown in (b) (the frequency domain resource carrying LP-WUS) are completely identical in the frequency domain.

[0152] Optionally, when the first frequency domain resource and the second frequency domain resource are located in the same set of frequency domain resources, the first rule may include: the center (i.e., the center frequency) of the first frequency domain resource is aligned (or the same) with the center of the second frequency domain resource, and the size of the first frequency domain resource is different from the size of the second frequency domain resource. For example, the first frequency domain resource may be larger than the second frequency domain resource. Continuing to refer to FIG7, the second frequency domain resource shown in (c-1) (the frequency domain resource carrying LP-SS) is smaller than the first frequency domain resource shown in (b) (the frequency domain resource carrying LP-WUS), and the centers of the second frequency domain resource shown in (c-1) and the first frequency domain resource shown in (b) are aligned.

[0153] Optionally, when the first frequency domain resource and the second frequency domain resource are located in the same set of frequency domain resources, the first rule may include: the center of the first frequency domain resource and the center of the second frequency domain resource may not be aligned.

[0154] In some embodiments, the second frequency domain resource may belong to one or more of the multiple candidate synchronization signal frequency domain resources in the same frequency domain resource set, and the multiple candidate synchronization signal frequency domain resources satisfy one of the following: the multiple candidate synchronization signal frequency domain resources do not overlap with each other; the multiple candidate synchronization signal frequency domain resources can overlap with each other; the center of some or all of the multiple candidate synchronization signal frequency domain resources is aligned with the center of the first frequency domain resource.

[0155] It should be noted that the frequency domain resource of any one of the multiple candidate synchronization signal frequency domain resources can be smaller than the first frequency domain resource.

[0156] It should be noted that the overlap or non-overlap of frequency domain resources among multiple candidate synchronization signals refers to the frequency domain, and there are no restrictions on the overlap in the time domain. Multiple candidate synchronization signal frequency domain resources can include a first candidate frequency domain resource and a second candidate frequency domain resource. Overlap between the first and second candidate frequency domain resources can mean that, in the frequency domain, the first and second candidate frequency domain resources overlap; in the time domain, the first and second candidate frequency domain resources may or may not overlap. Non-overlap between the first and second candidate frequency domain resources can mean that, in the frequency domain, the first and second candidate frequency domain resources do not overlap; in the time domain, the first and second candidate frequency domain resources may or may not overlap.

[0157] It should be noted that overlap between the first candidate frequency domain resources and the second candidate frequency domain resources can mean that some or all of the frequency domain resources of the first candidate frequency domain resources are the same as those of the second candidate frequency domain resources. Non-overlap between the first candidate frequency domain resources and the second candidate frequency domain resources can mean that no frequency domain resource in the first candidate frequency domain resources is the same as that in the second candidate frequency domain resources.

[0158] It should be noted that the non-overlapping of multiple candidate synchronization signal frequency domain resources can include any two of them not overlapping in the frequency domain. Conversely, the possibility of overlap between multiple candidate synchronization signal frequency domain resources can include any two of them not overlapping in the frequency domain, or overlapping in the frequency domain.

[0159] It should be noted that when the synchronization signal includes LP-SS, the frequency domain resources of the candidate synchronization signal can also be referred to as the candidate frequency domain resource set of LP-SS.

[0160] Referring again to Figure 7, in (c-2), the DL BWP contains three candidate frequency domain resource sets for LP-SS. The center frequencies of these three LP-SS candidate frequency domain resource sets are not aligned. Furthermore, in the frequency domain, these three LP-SS candidate frequency domain resource sets overlap. Compared to (b), the center frequencies of two of the three LP-SS candidate frequency domain resource sets are not aligned with the center frequency of the LP-WUS candidate frequency domain resource set.

[0161] In some embodiments, the synchronization signal may be transmitted using frequency hopping.

[0162] In some embodiments, the first frequency domain resource may reside in a first frequency domain resource set, and the second frequency domain resource may reside in a second frequency domain resource set. For example, when the synchronization signal includes PSS / SSS / SSB, the first frequency domain resource may reside in the first frequency domain resource set, and the second frequency domain resource may reside in the second frequency domain resource set.

[0163] In an optional implementation, the network device can configure a first frequency domain resource set and a second frequency domain resource set, respectively. The first and second frequency domain resource sets configured by the network device can satisfy the first rule.

[0164] The first frequency domain resource set may include guard intervals. Guard intervals may be distributed on both sides of the first frequency domain resource set. A detailed description of guard intervals has been provided above and will not be repeated here.

[0165] The first set of frequency domain resources may include the OOK modulation bandwidth, i.e., the bandwidth occupied by the signal modulated by OOK. The guard interval may be located on both sides outside the OOK modulation bandwidth to separate the OOK modulated signal from other frequency domain resources.

[0166] As mentioned above, the frequency domain resource set may include BWPs (Boundary Protected Positions). Based on this, the first frequency domain resource set may be the BWP to which the first resource belongs, and the second frequency domain resource set may be the BWP to which the second resource belongs. Alternatively, the frequency domain resource set may include the frequency domain resources actually used by the signal. For example, the first frequency domain resource set may be the frequency domain resources in the BWP to which the first resource belongs that do not contain guard intervals. The second frequency domain resource set may be the frequency domain resources actually used by the synchronization signal. Taking a synchronization signal including an SSB as an example, the second frequency domain resource set may be 20 PRBs (Personalized Guarded Positions).

[0167] In optional implementations, the first rule may include: a first frequency domain resource set and a second frequency domain resource set may have an association relationship. For example, a network device may configure a first frequency domain resource set (but may not configure a second frequency domain resource set). Based on the first frequency domain resource set and the association relationship, the second frequency domain resource set can be determined. Alternatively, a network device may configure a second frequency domain resource set (but may not configure a first frequency domain resource set). Based on the second frequency domain resource set and the association relationship, the first frequency domain resource set can be determined.

[0168] In some embodiments, the association between the first frequency domain resource set and the second frequency domain resource set can be represented by the frequency domain interval (or frequency domain offset) between them. For example, the location of the first frequency domain resource set can be determined by the following information: the location of the second frequency domain resource set; and the frequency domain interval between the first and second frequency domain resource sets. Similarly, the location of the second frequency domain resource set can be determined by the following information: the location of the first frequency domain resource set; and the frequency domain interval between the second and second frequency domain resource sets.

[0169] In some embodiments, the frequency domain spacing can be: the interval between the start frequency of the first frequency domain resource set and the start frequency of the second frequency domain resource set; the interval between the center frequency of the first frequency domain resource set and the center frequency of the second frequency domain resource set; or, the interval between the end frequency of the first frequency domain resource set and the end frequency of the second frequency domain resource set. In other words, the reference point for calculating the frequency domain spacing can be the start frequency, the center frequency, or the end frequency.

[0170] It should be noted that the association between the first frequency domain resource set and the second frequency domain resource set can satisfy one or more of the following: predefined, configured by the network device. For example, the frequency domain interval between the first frequency domain resource set and the second frequency domain resource set can satisfy one or more of the following: predefined, configured by the network device.

[0171] It should be noted that the first frequency domain resource set may be different from or the same as the second frequency domain resource set. If there is a correlation between the first and second frequency domain resource sets, whether they are the same can be determined based on that correlation.

[0172] In some embodiments, the first rule may include: the frequency domain interval between the first frequency domain resource set and the second frequency domain resource set is less than or equal to a first threshold. The first threshold may be greater than or equal to 0. The frequency domain interval can be represented by ΔF, and the first threshold can be represented by ΔF. max This is indicated by the following: For example, when a network device is configured with a first frequency domain resource set and a second frequency domain resource set respectively, the frequency domain interval between the first and second frequency domain resource sets configured by the network device is less than or equal to a first threshold. As another example, when the first and second frequency domain resource sets are associated, the frequency domain interval between the first and second frequency domain resource sets must be less than or equal to the first threshold.

[0173] When the frequency domain interval between the first frequency domain resource set and the second frequency domain resource set is less than or equal to the first threshold, the terminal device can obtain the synchronization of the first signal more accurately by listening to the synchronization signal.

[0174] Figure 8 is a schematic diagram of a first frequency domain resource set and a second frequency domain resource set provided in an embodiment of this application. In Figure 8, the first signal may include LP-WUS, and the synchronization signal may include SSB. The first frequency domain resource set may be the BWP of LP-WUS; the second frequency domain resource set may be the BWP of SSB. Reference point A1 may be the starting frequency of the BWP of SSB. Reference point A2 may be the center frequency of the BWP of SSB. Reference point A3 may be the ending frequency of the BWP of SSB. Reference point B1 may be the starting frequency of the BWP of LP-WUS. Reference point B2 may be the center frequency of the BWP of LP-WUS. Reference point B3 may be the ending frequency of the BWP of LP-WUS. The frequency domain interval may be the interval between reference point A1 and reference point B1; or, the frequency domain interval may be the interval between reference point A2 and reference point B2; or, the frequency domain interval may be the interval between reference point A3 and reference point B3. In addition, as shown in Figure 8, the frequency domain interval ΔF is less than the first threshold ΔF. max .

[0175] Figure 8 illustrates the concept using SSB as the synchronization signal. Figure 9 follows, illustrating the concept using synchronization signals including SSB and LP-SS. As shown in Figure 9, the frequency domain interval between the BWP of SSB and the BWP of LP-WUS can be ΔF1. The frequency domain interval between the BWP of LP-SS and the BWP of LP-WUS can be ΔF2. ΔF1 < ΔF max ΔF2 < ΔF max .

[0176] In some embodiments, the first frequency domain resource may belong to the first allocated resource. The first allocated resource may be the total frequency domain resource indicated or allocated by the network device for the first signal. The first allocated resource may include the first transmission frequency domain resource that the first signal can occupy and the first protection frequency domain resource occupied by the guard interval. Taking the first signal as an example of OOK modulation, the first allocated resource may be the frequency domain resource transmitted by the OOK signal; the first protection frequency domain resource may be the frequency domain resource that the OOK signal cannot occupy.

[0177] Optionally, the first allocated resources can satisfy the following condition: First allocated resources = First transmission frequency domain resources + First protection frequency domain resources.

[0178] The information of the first allocated resource may include one or more of the following: the size of the first allocated resource, the location of the first allocated resource, the ratio of the first transmission frequency domain resource to the first allocated resource, the ratio of the first transmission frequency domain resource to the first protection frequency domain resource, the ratio of the first protection frequency domain resource to the first allocated resource, the size of the first transmission frequency domain resource, the location of the first transmission frequency domain resource, the size of the first protection frequency domain resource, and the location of the first protection frequency domain resource.

[0179] It should be noted that the location of a frequency domain resource can be represented by one or more of the following information about the frequency domain resource: center frequency, start frequency, and end frequency.

[0180] For the first protection frequency domain resource, it can be represented by a double-sided protection interval, or by a single-sided protection interval. The single-sided protection interval can be either the higher-positioned protection interval or the lower-positioned protection interval among the double-sided protection intervals. Based on this, the information of the first allocated resource can be related to the single-sided protection interval and / or the double-sided protection intervals.

[0181] For example, the ratio of the first transmission frequency domain resources to the first protection frequency domain resources may include one or more of the following: the ratio of the first transmission frequency domain resources to the frequency domain resources occupied by the single-sided protection interval; the ratio of the first transmission frequency domain resources to the frequency domain resources occupied by the double-sided protection interval.

[0182] For example, the ratio of the first protection frequency domain resources to the first allocation resources may include one or more of the following: the ratio of the frequency domain resources occupied by the single-sided protection interval to the first allocation resources; the ratio of the frequency domain resources occupied by the double-sided protection interval to the first allocation resources.

[0183] For example, the size of the first protection frequency domain resource may include one or more of the following: the size of the frequency domain resource occupied by a single-sided protection interval; the size of the frequency domain resource occupied by a double-sided protection interval.

[0184] For example, the location of the first protection frequency domain resource may include one or more of the following: the location of the frequency domain resource occupied by a single-sided protection interval; the location of the frequency domain resource occupied by a double-sided protection interval.

[0185] The information for the first resource allocation satisfies one or more of the following: predefined, configured by network devices.

[0186] For example, some information in the first allocated resource information is predefined, while other information is configured by the network device. Exemplarily, the positions of the first transmission frequency domain resource and the first protection frequency domain resource can be predefined. For example, it can be predefined that the first transmission frequency domain resource is located in the middle, and the first protection frequency domain resources are located on either side. Exemplarily, one or more of the following can be configured by the network device: the ratio of the first transmission frequency domain resource to the first allocated resource; the ratio of the first transmission frequency domain resource to the first protection frequency domain resource; and the ratio of the first protection frequency domain resource to the first allocated resource.

[0187] In some embodiments, the network device may first indicate the size and location of the first allocated resource. Further, the network device may indicate information related to the first transmission frequency domain resource from the information of the first allocated resource. The information related to the first transmission frequency domain resource may include one or more of the following: the size of the first transmission frequency domain resource, the location of the first transmission frequency domain resource, the ratio of the first transmission resource to the first allocated resource, etc. Further, the network device may indicate information related to the first protection frequency domain resource. The information related to the first protection frequency domain resource may include one or more of the following: the size of the first protection frequency domain resource, the location of the first protection frequency domain resource, the ratio of the first protection frequency domain resource to the first allocated resource, and the ratio of the first transmission frequency domain resource to the first protection frequency domain resource.

[0188] In some embodiments, the network device may first indicate information related to the first transmission frequency domain resources, and may not indicate information related to the first protection frequency domain resources. Optionally, when the network device sends the first signal, it may determine the size of the guard interval on both sides according to a predefined definition. Alternatively, the network device may further indicate information related to the first protection frequency domain resources.

[0189] In some embodiments, the second frequency domain resource may belong to the second allocated resource. The second allocated resource may be the total frequency domain resource indicated or allocated by the network device for the synchronization signal. The second allocated resource may include the second transmission frequency domain resource that the synchronization signal can occupy and the second protection frequency domain resource occupied by the guard interval. Taking the synchronization signal through OOK modulation as an example, the second allocated resource may be the frequency domain resource transmitted by the OOK signal; the second protection frequency domain resource may be the frequency domain resource that the OOK signal cannot occupy.

[0190] Optionally, the second allocated resources can satisfy the following condition: second allocated resources = second transmission frequency domain resources + second protection frequency domain resources.

[0191] Information about the second allocated resources may include one or more of the following: the size of the second allocated resources, the location of the second allocated resources, the ratio of the second transmission frequency domain resources to the second allocated resources; the ratio of the second transmission frequency domain resources to the second protection frequency domain resources; the ratio of the second protection frequency domain resources to the second allocated resources; the size of the second transmission frequency domain resources; the location of the second transmission frequency domain resources; the size of the second protection frequency domain resources; and the location of the second protection frequency domain resources.

[0192] Regarding the second protection frequency domain resources, these resources can be represented by either bilateral protection intervals or unilateral protection intervals. A unilateral protection interval can be either the higher or lower protection interval among the bilateral protection intervals. Based on this, the information regarding the second allocated resources can be related to the unilateral and / or bilateral protection intervals. For example, the ratio of the second transmission frequency domain resources to the second protection frequency domain resources can include one or more of the following: the ratio of the second transmission frequency domain resources to the frequency domain resources occupied by the unilateral protection intervals; the ratio of the second transmission frequency domain resources to the frequency domain resources occupied by the bilateral protection intervals. Similarly, the ratio of the second protection frequency domain resources to the second allocated resources can include one or more of the following: the ratio of the frequency domain resources occupied by the unilateral protection intervals to the second allocated resources; the ratio of the frequency domain resources occupied by the bilateral protection intervals to the second allocated resources. Furthermore, the size of the second protection frequency domain resources can include one or more of the following: the size of the frequency domain resources occupied by the unilateral protection intervals; the size of the frequency domain resources occupied by the bilateral protection intervals. For example, the location of the second protection frequency domain resources may include one or more of the following: the location of the frequency domain resources occupied by a single-sided protection interval; the location of the frequency domain resources occupied by a double-sided protection interval.

[0193] The information of the second allocated resource satisfies one or more of the following: predefined, configured by the network device. For example, part of the information of the second allocated resource is predefined, and another part is configured by the network device. Exemplarily, the positions of the second transmission frequency domain resource and the second protection frequency domain resource can be predefined. For example, it can be predefined that the second transmission frequency domain resource is located in the middle, and the positions of the second protection frequency domain resources can be located on both sides. Exemplarily, one or more of the following can be configured by the network device: the ratio of the second transmission frequency domain resource to the second allocated resource; the ratio of the second transmission frequency domain resource to the second protection frequency domain resource; the ratio of the second protection frequency domain resource to the second allocated resource.

[0194] In some embodiments, the network device may first indicate the size and location of the second allocated resource. The network device may further indicate information related to the second transmission frequency domain resource from the information of the second allocated resource. The information related to the second transmission frequency domain resource may include one or more of the following: the size of the second transmission frequency domain resource, the location of the second transmission frequency domain resource, and the ratio of the second transmission resource to the second allocated resource. Further, the network device may indicate information related to the second protection frequency domain resource. The information related to the second protection frequency domain resource may include one or more of the following: the size of the second protection frequency domain resource, the location of the second protection frequency domain resource, the ratio of the second protection frequency domain resource to the second allocated resource, and the ratio of the second transmission frequency domain resource to the second protection frequency domain resource.

[0195] In some embodiments, the network device may first indicate information related to the second transmission frequency domain resources, and may not indicate information related to the second protection frequency domain resources. Optionally, when the network device sends a synchronization signal, it may determine the size of the guard interval on both sides according to a predefined definition. Alternatively, the network device may further indicate information related to the second protection frequency domain resources.

[0196] It should be noted that the ratio of A to B mentioned above can be A / B or B / A. That is, this application does not restrict which term of A or B is in the denominator.

[0197] The previous section explained the relationship between the first and second resources in the frequency domain. The following section explains the relationship between the first and second resources in the time domain.

[0198] In some embodiments, the first resource may include a first temporal resource, and the second resource may include a second temporal resource. The first temporal resource and the second temporal resource can be associated, that is, they have an association relationship. For example, the second temporal resource can be determined through the first temporal resource. Similarly, the first temporal resource can be determined through the second temporal resource.

[0199] In some embodiments, the first time-domain resource and the second time-domain resource can be time-division multiplexed. That is, the first signal and the synchronization signal are transmitted in a time-division multiplexed manner in the time domain. For example, when the first frequency-domain resource and the second frequency-domain resource belong to the same set of frequency-domain resources, the first time-domain resource and the second time-domain resource can be time-division multiplexed.

[0200] In some embodiments, the first time-domain resource may belong to N candidate time-domain resources, where N can be a positive integer. The candidate time-domain resources can be used to transmit the first signal. In other words, the candidate time-domain resources can be time-domain listening resources or transmission resources for the first signal. Terminal devices can listen to the first signal on candidate time-domain resources, and network devices can transmit the first signal on candidate time-domain resources.

[0201] For example, the network device can transmit the first signal on N candidate time-domain resources. For instance, if it is necessary to wake up the second receiver, the network device can transmit the first signal on one or more of the N candidate time-domain resources. Conversely, if it is not necessary to wake up the second receiver, the network device may not transmit the first signal. Therefore, the terminal device may not receive the first signal on some candidate time-domain resources.

[0202] It should be noted that N can satisfy one or more of the following: predefined, configured by network devices, or specified by protocols.

[0203] In some embodiments, N candidate time-domain resources can be used to transmit M first signals. M can be greater than or equal to N. That is, each candidate time-domain resource can be used to transmit at least one first signal. The terminal device can listen to the first signal on a certain candidate time-domain resource and may receive the first signal.

[0204] In some embodiments, the second time-domain resource can be a periodically arranged resource. For example, a network device can configure a time-domain resource for transmitting a periodic synchronization signal. The network device can transmit the synchronization signal on the periodically arranged resource. The periodic arrangement of resources indicates that corresponding resources can appear at equal intervals (i.e., periods). For example, the period of the second time-domain resource can be 320ms. In other words, the network device can transmit a synchronization signal every 320ms, and the terminal device can listen to the synchronization signal.

[0205] Figure 10 is an example diagram of the arrangement of time-domain resources according to an embodiment of this application. In Figure 10, the synchronization signal includes LP-SS, that is, the second time-domain resource can be a time-domain resource capable of transmitting LP-SS. As shown in Figure 10, the second time-domain resource is arranged according to a period. The period is T. LP-SS .

[0206] In some embodiments, the second time-domain resources can be arranged according to the transmission requirements of the synchronization signal. For example, when a synchronization signal needs to be transmitted, the network device can schedule time-domain resources for transmitting the synchronization signal.

[0207] In some embodiments, the second time-domain resources may be periodically arranged, and the second time-domain resources may be arranged according to the transmission requirements of the synchronization signal. For example, when it is necessary to send a synchronization signal, the network device may send the synchronization signal on the periodically arranged time-domain resources for transmitting synchronization signals; when it is not necessary to send a synchronization signal, the synchronization signal will not be sent on the periodically arranged time-domain resources for transmitting synchronization signals.

[0208] The second time-domain resource can be associated with N candidate time-domain resources. That is, the second time-domain resource can be used to determine N candidate time-domain resources. Alternatively, the N candidate time-domain resources can be used to determine the second time-domain resource. For example, the association between the second time-domain resource and the N candidate time-domain resources can be related to the time-domain interval between them. Based on the second time-domain resource and this time-domain interval, the N candidate time-domain resources can be determined, thereby determining the first time-domain resource.

[0209] One possible implementation is to determine the target time-domain resource unit containing N candidate time-domain resources. Further, within the target time-domain resource unit, the time-domain resource sub-units containing the N candidate time-domain resources can be determined.

[0210] For example, the target time-domain resource unit can be the first time-domain resource unit containing N candidate time-domain resources. Alternatively, the target time-domain resource unit can include any one or more time-domain resource units containing the N candidate time-domain resources.

[0211] It should be noted that a temporal resource unit can include multiple temporal resource sub-units. For example, a temporal resource unit can be a frame, and a temporal resource sub-unit can be a symbol. That is, by determining the target frame where N candidate temporal resources are located, the symbols occupied by the N candidate temporal resources in the target frame can be determined.

[0212] In some embodiments, the interval between the time domain resource unit where the second time domain resource is located and the target time domain resource unit can be a first time interval. The target time domain resource unit can be determined based on the first time interval.

[0213] Optionally, multiple first time intervals may exist, and these multiple first time intervals may correspond one-to-one with multiple time-domain resource units where the N candidate time-domain resources are located. The multiple time-domain resource units where the N candidate time-domain resources are located can be determined according to the multiple first time intervals.

[0214] Optionally, there may be one first time interval, which may correspond to a specific time-domain resource unit where the N candidate time-domain resources are located. By determining the specific time-domain resource unit where the N candidate time-domain resources are located, all time-domain resource units where the N candidate time-domain resources are located can be further determined.

[0215] It should be noted that the first time interval can satisfy one or more of the following: predefined, configured by the network device.

[0216] It should be noted that, considering that the first time-domain resource can be determined by the time-domain resource unit where the second time-domain resource is located, the time-domain resource unit where the second time-domain resource is located can also be called the reference time-domain resource unit. Taking a frame as an example, the reference time-domain resource unit can be a reference frame.

[0217] Figure 11 is an example diagram illustrating the association between the second time-domain resource and N candidate time-domain resources provided in an embodiment of this application. As shown in Figure 11, the second time-domain resource can be associated with 8 candidate time-domain resources, i.e., N=8. The terminal device can listen for the first signal on the 8 candidate time-domain resources. In the scenario shown in Figure 8, the 4th candidate time-domain resource actually transmits the first signal; therefore, the terminal device can receive the first signal on the 4th candidate time-domain resource, but cannot receive the first signal on other candidate time-domain resources.

[0218] In Figure 11, the first time interval is represented by a "temporal offset". The frames containing the N candidate temporal resources are called LP-WUS frames. The first LP-WUS frame can be the target frame. Based on the reference frame containing the second temporal resource and the temporal offset, the temporal location of the target frame can be determined.

[0219] The time interval between the first time-domain resource sub-unit of the target time-domain resource unit and the time-domain resource sub-units occupied by the N candidate time-domain resources in the target time-domain resource unit is the second time interval. Alternatively, the index of the time-domain resource sub-units occupied by the N candidate time-domain resources in the target time-domain resource unit can be the second time interval. The time-domain resource sub-units occupied by the N candidate time-domain resources in the second target time-domain resource unit can be determined based on the second time interval.

[0220] Optionally, multiple second time intervals may exist, and these multiple second time intervals may correspond one-to-one with multiple time-domain resource sub-units that the first signal can occupy in the target time-domain resource unit. Based on the multiple second time intervals, it can be determined which time-domain resource sub-units in the target time-domain resource unit are used to listen to the first signal.

[0221] Optionally, there may be a second time interval, which may correspond to the first time-domain resource sub-unit that the first signal can occupy in the target time-domain resource unit. Based on this second time interval, the first time-domain resource sub-unit that the first signal can occupy in the target time-domain resource unit can be determined, and then the other time-domain resource sub-units that the first signal can occupy in the target time-domain resource unit can be determined.

[0222] It should be noted that, within the target time-domain resource unit, the number of time-domain resource sub-units that the first signal can occupy can satisfy one or more of the following: predefined, configured by the network device. When the number of time-domain resource sub-units corresponds one-to-one with the listening timing of the first signal, the number of listening timings of the first signal within the target time-domain resource unit can satisfy one or more of the following: predefined, configured by the network device.

[0223] It should be noted that the second time interval can satisfy one or more of the following: predefined, configured by the network device.

[0224] In some embodiments, the time interval between the time domain resource subunit where the second time domain resource is located and the time domain resource subunits where the N candidate time domain resources are located can be a third time interval, and the time domain resource subunits where the N candidate time domain resources are located are determined based on the third time interval.

[0225] For example, the third time interval can be the interval between the first time-domain resource sub-unit containing the second time-domain resource and the first time-domain resource sub-unit containing the N candidate time-domain resources. Alternatively, the third time interval can be the interval between the last time-domain resource sub-unit containing the second time-domain resource and the first time-domain resource sub-unit containing the N candidate time-domain resources.

[0226] Optionally, multiple third time intervals may exist. These multiple third time intervals can correspond one-to-one with multiple time-domain resource sub-units containing the N candidate time-domain resources. Based on these multiple third time intervals, the multiple time-domain resource sub-units containing the N candidate time-domain resources can be determined separately.

[0227] Optionally, there may be one third time interval. This third time interval can correspond to any one of the N candidate time-domain resources in a time-domain resource sub-unit. For example, any one time-domain resource sub-unit can be the first among the N candidate time-domain resources. That is, based on this one third time interval, the first time-domain resource sub-unit among the N candidate time-domain resources can be determined.

[0228] In some embodiments, where some of the N candidate time-domain resources are capable of transmitting a first signal for a terminal device, the N candidate time-domain resources can be determined based on one or more of the following information: the identifier of the terminal device (UE ID); the identifier of the terminal group to which the terminal device belongs (UE group ID); and the identifier of the subgroup of the terminal device (UE subgroup ID). That is, there can be a mapping relationship between the N candidate time-domain resources and each terminal device, and the mapping relationship can be determined based on the aforementioned information of the terminal device.

[0229] It is understandable that some of the N candidate time-domain resources can be used to transmit the first signal for a specific terminal device, while another portion of the N candidate time-domain resources are not used to transmit the first signal for that terminal device. For example, the other portion of the candidate time-domain resources can be used to transmit the first signal for other terminal devices. Based on one or more of the following: the identifier of the terminal device, the identifier of the terminal group, and the identifier of the sub-terminal group, the terminal device can determine the candidate time-domain resources that need to be monitored, and the network device can determine the candidate time-domain resources to be used to send the first signal to that terminal device.

[0230] In some embodiments, the monitoring results of the synchronization signal can be used to indicate one or more of the following information: whether the first signal was transmitted among the N candidate time-domain resources; the candidate time-domain resources among the N candidate time-domain resources that transmitted the first signal; and the candidate time-domain resources among the N candidate time-domain resources that did not transmit the first signal. The monitoring results of the synchronization signal may include a sequence of synchronization signals. For example, a network device can use the sequence of synchronization signals to indicate the above-mentioned information about the first signal. Similarly, a terminal device can use the sequence of synchronization signals to determine the above-mentioned information about the first signal.

[0231] Optionally, the synchronization signal can be associated with a terminal device. For example, the synchronization signal can be associated with a terminal device through one or more of the following information: the identifier of the terminal device; the identifier of the terminal group to which the terminal device belongs; and the identifier of the sub-terminal group to which the terminal device belongs. The association can indicate which terminal devices need to listen to the first signal associated with the synchronization signal.

[0232] In some embodiments, the time-domain resource of the PO can be a third time-domain resource. A first time-domain resource can be associated with a third time-domain resource. That is, the first time-domain resource can be determined through the third time-domain resource. A fourth time interval can exist between the third time-domain resource and the first time-domain resource. The first time-domain resource can be determined based on the fourth time interval and the third time-domain resource.

[0233] Figure 12 is an example diagram of a first signal, a synchronization signal, and time-domain resources occupied by the PO according to an embodiment of this application. As shown in Figure 12, the first receiver listens to the periodically transmitted synchronization signal (the synchronization signal in Figure 12 includes LP-SS) to obtain necessary synchronization and perform RRM measurements. Based on the time-domain resources occupied by the PO and the fourth time interval T4, the first time-domain resources (i.e., the resources actually used for transmitting LP-WUS in Figure 12) can be determined. When the first signal (the first signal in Figure 12 includes LP-WUS) is detected, the first receiver needs to wake up the second receiver to receive paging. During T4, the second receiver wakes up from ultra-deep sleep.

[0234] In some embodiments, the fourth time interval between the time domain resources occupied by the PO and the first time domain resources may be relatively large compared to the first time interval between the second time domain resources and the first time domain resources. For example, according to 3GPP R18 research, the transition of an MR from a deep sleep state to a listening paging state requires a ramp-up time and necessary synchronization, which takes at least approximately 400 ms. Therefore, the time interval between LP-WUS and PO needs to be at least greater than 400 ms. As mentioned above, the period of the synchronization signal (e.g., LP-SS) can be considered to be 320 ms. Therefore, the time interval from LP-WUS to the nearest LP-SS is relatively smaller than the time interval to PO.

[0235] In some embodiments, the temporal resources corresponding to the first resource may be periodically arranged. Based on the periodic arrangement, the network device and / or terminal device can determine the first resource. For example, the first resource may belong to multiple wake-up frames. Wake-up frames may be periodically arranged.

[0236] Multiple periodically arranged wake-up frames can be represented by one or more of the following: a period, or one or more offsets within a period. For example, for a frame numbered nSFN, if nSFN mod x = y, then the frame can be a wake-up frame. Here, the value of x is equal to the period of the wake-up frame, and y is the index or offset of the time-domain resource that can transmit the first signal within the period.

[0237] The following explanation uses Figure 13 as an example. In Figure 13, the period of the wake-up frame is represented by T. The value of y is 2 and 4. As shown in Figure 13, within the window corresponding to period T, frames #x+2 and #x+4 can be wake-up frames.

[0238] In some embodiments, the time-domain resources in the wake-up frame that can be used to transmit the first signal can be indicated by the following parameter: the time-domain position occupied by the time-domain resources in the wake-up frame that can be used to transmit the first signal. For example, the time-domain resources in the wake-up frame that can be used to transmit the first signal can be indicated by the following parameter: the symbols occupied by the time-domain resources in the wake-up frame that can be used to transmit the first signal. That is, the symbols that the first signal can occupy can be directly determined in the wake-up frame.

[0239] It should be noted that the time-domain position that the first signal can occupy in the wake-up frame can be predefined and / or configured by the network device. In the case of network device configuration, the time-domain position that the first signal can occupy in the wake-up frame can be configured via RRC signaling.

[0240] The temporal position that the first signal can occupy in the wake-up frame can be determined by the symbol start position within the wake-up frame. The network device can configure one or more symbol start positions.

[0241] In some embodiments, the temporal resources available for transmitting the first signal can be determined in multiple levels. For example, the temporal resources available for transmitting the first signal in a wake-up frame can be indicated by the following parameters: the subframe number occupied by the temporal resources available for transmitting the first signal in the wake-up frame, and the symbols occupied in the subframe number. That is, one or more subframes that the first signal can occupy in the wake-up frame can be determined first, and then one or more symbols that the first signal can occupy in that subframe can be determined. The one or more symbols that the first signal can occupy in that subframe can be indicated by the offset of the symbols in the subframe.

[0242] Referring again to Figure 13, in wake-up frame #x+2, it can be determined that the subframes that the first signal can occupy are subframe #3 and subframe #6. For subframe #3, it can be determined that the symbol that the first signal can occupy is the gray part.

[0243] It should be noted that the length of time-domain resources that the first signal can occupy can satisfy one or more of the following: as agreed by the protocol, or configured by the network device. The length of time-domain resources that the first signal can occupy can be the number of symbols. For example, the length of time-domain resources that the first signal can occupy can be the number of consecutive symbols.

[0244] Optionally, the determined first time-domain resource can be the time-domain resource corresponding to the transmission of the first signal by a single beam, and the first signal and the synchronization signal can be QCL.

[0245] Optionally, if the first signal includes LP-WUS, the determined LP-WUS time-domain resource (i.e., the first time-domain resource) can be a time-domain resource of an LP-WUS burst set. The LP-WUS burst set can contain X LP-WUS time-domain resources, where X can be the same as the number of beams used. LP-WUS can be QCL with the synchronization signal.

[0246] As mentioned above, the periodically arranged first time-domain resource can be configured by the network device. For example, the IE in the following RRC signaling can be used to configure the periodically arranged first time-domain resource.

[0247] The first cell can be used to indicate the period of the first signal. The first cell can be represented by LPWUS-periodicityServingCell.

[0248] The second information element can be used to configure the position of the wake-up frame within a period (i.e., one or more offsets within a period). The second information element can be represented by LPWUS-positionInPeriodicity.

[0249] The third information element can be used to indicate the subcarrier spacing of the first signal. The third information element can be represented by LPWUS-SubcarrierSpacing.

[0250] The fourth information cell can be used to indicate the length of the first time-domain resource. The fourth information cell can be represented by LPWUS-Duration.

[0251] The fifth cell can be used to indicate the temporal location of the first signal within the wake-up frame. The fifth cell may include one or more offsets. The fifth cell may include one or more levels of offsets. The fifth cell can be represented by LPWUS-timeoffset.
