[0040] It should be understood that all or part of the functions of the communication device in this application can also be implemented through software functions running on hardware, or through virtualization functions instantiated on a platform (such as a cloud platform).

[0041] Discontinuous reception (DRX)

[0042] To reduce terminal power consumption, some communication systems (such as LTE and NR systems) have introduced the DRX mechanism. The DRX mechanism eliminates the need for terminals to keep their receivers powered on when not receiving data, instead enabling them to enter a discontinuous reception state, thereby saving power. The DRX mechanism involves configuring a DRX cycle for the terminal. A DRX cycle consists of an "on duration" and an "opportunity for DRX." During the on duration, the terminal monitors and receives downlink channels and signals, including the PDCCH. During the inactivity period, the terminal does not receive downlink channels and signals, such as the PDCCH, to reduce power consumption.

[0043] The evolution of communication systems has placed higher demands on terminal energy conservation. For some DRX mechanisms, during each activation period, terminals must continuously monitor the PDCCH to determine whether the network equipment is scheduling data for them. However, for most terminals, there may be long periods without the need to receive data, yet they still need to periodically wake up to monitor for possible downlink transmissions. There is room for further optimization of energy conservation methods for these terminals.

[0044] To address the above issues, energy-saving signals have been introduced in some communication standards (such as the 3GPP R16 standard). Energy-saving signals can achieve further energy saving for terminal devices in the radio resource control (RRC) connected state (RRC_CONNECTED). Energy-saving signals can be used in conjunction with the DRX mechanism. For example, before entering the DRX activation period, the terminal can first determine whether it needs to receive data during the DRX activation period based on the indication of the energy-saving signal. When the terminal has data to transmit in a DRX cycle, the energy-saving signal "wakes up" the terminal, and accordingly, the terminal monitors the PDCCH during the DRX activation period. Conversely, when the terminal has no data to transmit in a DRX cycle, the energy-saving signal does not "wake up" the terminal, and accordingly, the terminal does not need to monitor the PDCCH during the DRX activation period. This DRX mechanism combined with energy-saving signals, if the energy-saving signal does not wake up the terminal in a DRX cycle, the terminal does not need to monitor the PDCCH even if it is in the DRX activation period, thereby achieving energy saving.

[0045] Some communication standards, such as 3GPP Release 17, have further established a Terminal Energy Saving Enhancement Project. This project further standardizes energy saving for terminals in the RRC Idle (RRC_IDLE) and RRC Deactivated (RRC_INACTIVE) states. Power consumption for terminals in the RRC_IDLE and RRC_INACTIVE states primarily stems from periodic discontinuous reception (DP) paging, including time-frequency synchronization recovery and automatic gain control (AGC) before the PO arrives, as well as power consumption during DP detection of the PDCCH.

[0046] To reduce power consumption during paging, relevant standards introduce a power-saving signal for paging reception. This power-saving signal can be called a PEI. The PEI can be used to indicate whether a terminal needs to receive a paging call before its PO arrives. In other words, the PEI can be used to indicate whether to "wake up" the terminal before its PO arrives.

[0047] PEI

[0048] A PEI monitoring occasion (PEI-O) is a collection of multiple physical downlink control channel (PDCCH) monitoring occasions.

[0049] In some embodiments, when nrofPDCCH-MonitoringOccasionPerSSB-InPO is not configured, PEI-O can be a set of S consecutive PDCCH monitoring occasions. Where S is the number of actual transmitted SSBs determined by ssb-PositionsInBurst in system information broadcast 1 (SIB1). In PEI-O, the quasi co-location (QCL) of the Kth PEI PDCCH monitoring occasion can be the same as the Kth PDCCH monitoring occasion paged in PO (the reference of the QCL is the SSB).

[0050] In unlicensed spectrum, PEI-O can be a set of (S*X) consecutive PDCCH monitoring opportunities. Among them, S is the number of actual transmitted SSBs determined according to ssb-PositionsInBurst in SIB1. If nrofPDCCH-MonitoringOccasionPerSSB-InPO is configured, X takes the configured value, otherwise X=1. The (x*S+K)th PDCCH monitoring opportunity in the PEI monitoring opportunity corresponds to the Kth SSB transmitted, where x=0, 1, ..., X-1, K=1, 2..., S. If X>1, when the terminal detects a PEI in the PEI monitoring opportunity, the terminal does not need to continue to monitor the subsequent monitoring opportunities associated with the PEI monitoring opportunity.

[0051] Mapping of PEI and PO

[0052] Network equipment can configure multiple POs for each paging frame (PF). On the one hand, if each PEI corresponds to a PO, there will be a large number of independent PEIs, which will increase the PEI overhead. On the other hand, if each PEI corresponds to a 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 PO or multiple POs. When designing PEI, in order to reduce PEI overhead and avoid PEI overlap, a mapping mechanism similar to the WUS in the 3GPP R15 / 16 standard was finally determined, that is, one PEI can be associated with one PO or multiple POs.

[0053] In some embodiments, one PEI can be associated with POnumPerPEI POs. As shown in FIG2 , POnumPerPEI can be 4. That is, in FIG2 , one PEI can be associated with 4 POs.

[0054] Optionally, the POnumPerPEI POs associated with a PEI may be in one or more PFs, and the maximum number of PFs associated with a PEI is 2.

[0055] Optionally, POnumPerPEI is N×N s Where N is the number of paging frames in a paging cycle, N s It can be the number of POs in a paging frame. POnumPerPEI can be configured through SIB and its value range can be {1, 2, 4, 8}.

[0056] Location of PEI-O

[0057] The terminal can determine the position 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 monitoring opportunity of the PEI-O). The following is an example with reference to Figure 2. The position of the PEI-O can be determined through steps 1 and 2.

[0058] Step 1: Determine the reference frame and use the starting point of the reference frame as the reference point.

[0059] The reference frame can be determined based on the first PF among all PFs associated with the PEI (when a PEI is associated with multiple POs, the associated POs may be located in different PFs) and a frame-level offset value.

[0060] The frame-level offset value from the first PF among all PFs associated with the PEI to the reference frame can be configured through the SIB.

[0061] Step 2: Determine the position of the first PDCCH monitoring opportunity in PEI-O based on the reference point and the symbol-level offset value.

[0062] The symbol-level offset value from the reference point to the first PDCCH monitoring opportunity in PEI-O may be configured through SIB. For example, the symbol-level offset value may be provided by firstPDCCH-MonitoringOccasionOfPEI-O.

[0063] LP-wake up signal (WUS) / wake up receiver (WUR)

[0064] Considering further energy-saving processing of terminals, some research projects (such as the 3rd generation partnership project (3GPP) R18) introduced LP-WUR and designed the corresponding LP-WUS signal. Specifically, when using LP-WUR to monitor the wake-up signal, the main receiver (MR) can be in an extremely low power state (such as ultra deep sleep state), thereby achieving energy saving for the entire terminal. LP-WUR can monitor the LP-WUS signal, and when it receives the LP-WUS signal from the network device, LP-WUR can wake up the main receiver.

[0065] The following uses the research of LP-WUS / WUR by the 3GPP RAN1 working group as an example for explanation.

[0066] When studying LP-WUS / WUR, the RAN1 working group reached a preliminary consensus on the accuracy of the LP-WUR oscillator, considering the following four options.

[0067] Option 1: The maximum frequency error of the oscillator is 200ppm, and the frequency drift of the oscillator is 0.1ppm / s.

[0068] Option 2: The maximum frequency error of the oscillator is 50ppm, and the frequency drift of the oscillator is 0.1ppm / s.

[0069] Option 3: The maximum frequency error of the oscillator is 10ppm, and the frequency drift of the oscillator is 0.05ppm / s.

[0070] Option 4: The maximum oscillator frequency error is 5ppm, and the oscillator frequency drift is 0.05ppm / s.

[0071] Consider that the maximum frequency error of the LP-WUR real-time clock (RTC) is 20ppm, and the frequency drift is 0.1ppm / s.

[0072] LP-WUS / WUR was studied in 3GPP Release 18 and published in the research report TR 38.869. LP-WUS / WUR was standardized in 3GPP Release 19. The following describes some of the standardization content and objectives in Release 19.

[0073] R19 standardizes a universal design of LP-WUS that can be applied to both IDLE / INACTIVE and CONNECTED states (RAN1, RAN4). Among them, 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 design of LP-WUS should ensure that in the IDLE / INACTIVE state, regardless of the receiver design used by LP-WUS, LP-WUS transmits the same information. At the same time, OFDM sequences can also carry information. LP-WUS can at least support duty-cycled monitoring mode.

[0074] First, for the IDLE / INACTIVE state, the process and configuration of LP-WUS triggering monitoring of paging messages are standardized, including at least: "configuration", "subgroup" and "conditions for entering / exiting LP-WUS monitoring" (RAN2, RAN1, RAN3, RAN4).

[0075] In addition, for the IDLE / INACTIVE state, an LP-SS with an LP-WUR standardized period of Yms can be used for serving cell synchronization and / or radio resource management (RRM) measurements (RAN1, RAN4). The LP-SS can be based on OOK-1 and / or OOK-4 waveforms, and may or may not superimpose an OFDM sequence on the OOK symbols. Whether or not to superimpose the OFDM sequence on the LP-SS is selected in the WI.

[0076] It should be noted that for LP-WUR that can receive the primary synchronization signal (PSS) / secondary synchronization signal (SSS) in the related technology, the PSS / SSS signal in the related technology can be used instead of LP-SS for synchronization and RRM measurement.

[0077] It should be noted that the value of Y needs to be determined in the WI phase. For example, 320m can be used as an initial value of Y.

[0078] Further standardization of RRM relaxation is carried out for the terminal's primary receiver measurements in the serving cell and neighboring cells. The RRM measurements of the terminal device's serving cell can be transferred from the MR to the LP-WUR, including the necessary condition design (RAN4, RAN2).

[0079] Secondly, for the CONNECTED state, it is necessary to standardize the process of LP-WUS triggering the terminal's primary receiver to monitor the PDCCH, including the activation and deactivation process of LP-WUS (RAN2, RAN1).

[0080] It should be noted that in the CONNECTED state, the terminal's main receiver will not enter the ultra-deep sleep state, and the terminal's radio resources (RR) / radio link monitoring (RLM) / bidirectional forwarding detection (BFD) / channel state information (CSI) measurements are performed by the main receiver.

[0081] It should be noted that the coverage performance of LP-WUS and LP-SS may be close to the coverage performance of physical uplink shared channel (PUSCH) message 3 (msg3).

[0082] The LP-WUS signal can be used to wake up the MR. Specifically, the terminal device's LR monitors the LP-WUS. When it receives an LP-WUS signal sent to the terminal device or to the terminal group to which the terminal device belongs, the LR wakes up the MR. Generally, the LR (low power receiver) can monitor the LP-WUS continuously or discontinuously using a duty-cycle method.

[0083] In some scenarios, the LP-WUR may experience time-frequency deviations while monitoring the LP-WUS due to the accuracy of its own oscillator. Therefore, it is necessary to monitor the synchronization signal for synchronization. In some discussions (e.g., 3GPP discussions), the LP-SS signal will be introduced for the LR. This LP-SS signal is mainly used for LP-WUR synchronization and / or for LR to perform measurements (e.g., RRM measurements). Of course, for high-capability LRs, it is possible to monitor the legacy PSS / SSS signals for synchronization.

[0084] In some scenarios, LR receivers can have different designs. They can be mainly divided into two categories of LR receiver designs. The following introduces Category 1 and Category 2 respectively.

[0085] Category 1 receivers can only perform synchronization and / or measurement based on LP-SS and do not have the ability to receive and detect PSS / SSS signals.

[0086] For a Category 2 receiver, which has the ability to receive and detect PSS / SSS signals, synchronization and / or measurement can be performed by receiving PSS / SSS signals instead of receiving LP-SS signals.

[0087] SSB

[0088] In some communication systems (e.g., NR systems), downlink synchronization is achieved by receiving the PSS and SSS signals in the SSB. Figure 3 shows the structure of an SSB. As shown in Figure 3, in the time domain, one SSB can occupy four OFDM symbols. In the frequency domain, one SSB can occupy 20 RBs.

[0089] In some implementations, the subcarriers of the SSB are numbered from 0 to 239. The PSS is located on the middle 127 SCs of symbol #0, and the SSS is located on the middle 127 SCs of symbol #2. To protect the PSS and SSS, multiple carriers are set to 0, respectively.

[0090] As shown in Figure 3, in SSB, the PBCH can occupy all of symbols #1 and #3, as well as symbol #2 excluding the SSS and guard band. After deducting the DMRS from symbols #1 and #3, the remaining 2*(240-60)=360 subcarriers are used for PBCH transmission. After deducting the DMRS from symbol #2, the number of SCs is (240-127-8-9)*3 / 4=72. Therefore, the PBCH has a total of 432 subcarriers.

[0091] As shown in FIG3 , DMRS is inserted into PBCH for transmission, and its starting position in SSB is determined by physical cell ID modulo 4.

[0092] SSB transmission

[0093] SSB can use TDD to send the same SSB in different directions through beams, so that terminal devices in all directions can receive the SSB. The series of SSBs sent by a network device is called a synchronized broadcast block set (SS BURST SET).

[0094] Figure 4 illustrates a scenario for transmitting SSBs. As shown in Figure 4, within a 5ms half-frame, the network device transmits eight SSBs, indexed from #0 to #7, via eight beams, covering different directions. As shown in Figure 4, these eight SSBs form a synchronized broadcast block set.

[0095] A terminal device may receive multiple SSBs with different signal strengths. The terminal device may select the one with the strongest signal strength as its own SSB beam.

[0096] As shown in Figure 4, UE1 and UE2 receive eight SSBs with varying signal strengths. Among the SSBs received by UE1, SSB#1 has the strongest signal strength. Therefore, the beam corresponding to SSB#1 can be used as UE1's SSB beam. Among the SSBs received by UE2, SSB#6 has the strongest signal strength. Therefore, the beam corresponding to SSB#6 can be used as UE2's SSB beam.

[0097] The period of the synchronized broadcast block set can refer to the time interval at which the synchronized broadcast block set repeats. Exemplarily, this period can default to 20 ms. In the scenario shown in Figure 4, the period of the synchronized broadcast block set is 20 ms. In the ServingCellConfigCommon information element (IE) of TS38.331, the range of values for the SSB period (ssb-periodicityServingCell) can be seen as ENUMERATED{ms5, ms10, ms20, ms40, ms80, ms160, spare2, spare1}.

[0098] Within 5 ms, the configuration of the SSB in the time domain can be as shown in Table 1. Table 1 gives the starting OFDM position of the SSB within 5 ms.

[0099] Table 1

[0100] Figure 5 is a schematic diagram of the distribution of SSBs for Case A when f ≤ 3 GHz. In Figure 5, the SSB period is 20 ms.

[0101] It should be noted that not all SSBs within the synchronized broadcast block set must be transmitted.

[0102] 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.

[0103] Among them, shortBitmap, mediumBitmap, and longBitmap can identify the indices of the actually transmitted SSBs in the cases of f < 3 GHz, 3 GHz < f < 6 GHz, and f > 6 GHz respectively. 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.

[0104] With the wide application of communication systems, various types of terminal devices have been introduced. For different types of terminal devices, the capabilities of the terminal devices are different. For example, some terminal devices with lower capabilities may not have the ability to receive SSBs, resulting in the inability of this type of terminal device to synchronize based on SSBs.

[0105] Taking LP terminal devices as an example, due to the poor oscillator accuracy of the low power receiver (LR) used in this type of terminal device, the time-frequency deviation during LP-WUS reception will become increasingly larger over time. Therefore, to ensure the signal reception performance of the LR, synchronization and / or measurement are required. However, due to the poor capabilities of this type of terminal device, it may not be able to receive SSB, let alone perform synchronization and / or measurement based on SSB.

[0106] Therefore, to address the above problems, a new signal for synchronization and / or measurement (hereinafter referred to as the first signal) is introduced. Compared with the traditional solution of synchronization and / or measurement based only on SSB, it helps to meet the synchronization and / or measurement needs of various types of terminal devices.

[0107] In some implementations, the first signal can be used for synchronization and / or measurement by an LP terminal device. For example, the first signal can be used for measurement and / or synchronization by a LR in the LP terminal device. For example, when the first signal is used for synchronization by an LP terminal device, the first signal can be used for synchronization of an LP-WUR. Therefore, the first signal is also referred to as an "LP-SS." For example, when the first signal is used for measurement by an LP terminal device, the first signal can be used by the LR of the LP terminal device to perform measurement.

[0108] In the embodiments of the present application, the above-mentioned measurement is not limited. In some implementations, the measurement may refer to radio resource management (RRM) measurement. For example, the measurement may be a measurement during the beam selection process.

[0109] In some implementations, the first signal may be modulated using an OOK approach to simplify a demodulation process of the first signal.

[0110] As mentioned above, in order to be compatible with different types of terminal devices in the communication system, a first signal is introduced for measurement and / or synchronization of the terminal device. However, the transmission method of the first signal is not currently specified, resulting in the terminal device being unable to synchronize and / or measure based on the first signal.

[0111] Therefore, an embodiment of the present application proposes a method for wireless communication, in which, as shown in step S610 in Figure 6, a network device sends a first signal to a terminal device, wherein the transmission resources of the first signal can be determined based on the first information, which helps to unify the understanding of the network device and the terminal device on the transmission resources of the first signal, so as to achieve synchronization and / or measurement based on the first signal.

[0112] In some scenarios, the terminal device monitors the first signal on the transmission resource of the first signal. Therefore, the transmission resource of the first signal can be called the transmission resource on which the terminal device monitors the first signal.

[0113] In the embodiments of the present application, there is no limitation on transmission resources. In some implementations, transmission resources may include one or more of the following: time domain resources, frequency domain resources, and code domain resources. Taking the example of transmission resources including time domain resources, where time domain resources may include symbols, time slots, subframes, frames, etc., of course, in the embodiments of the present application, transmission resources may also include other time domain resources introduced in future communication systems. Taking the example of transmission resources including frequency domain resources, where frequency domain resources may include subcarriers, frequency bands, bandwidths, etc., of course, in the embodiments of the present application, frequency domain resources may also include other frequency domain resources introduced in future communication systems. Taking the example of transmission resources including code domain resources, where code domain resources may include codebooks, codewords, etc., of course, in the embodiments of the present application, code domain resources may also include other code domain resources introduced in future communication systems.

[0114] In the embodiments of the present application, there are multiple ways to implement the first information. The first information in the embodiments of the present application will be introduced below in combination with Example 1 and Example 2 respectively.

[0115] Embodiment 1: The first information includes information about transmission resources of a second signal, wherein the second signal is associated with the first signal.

[0116] In the embodiment of the present application, determining the transmission resources of the first signal based on the first information can be understood as determining the transmission resources of the first signal based on the transmission resources of the second signal, which helps to simplify the complexity of configuring the transmission resources of the first signal.

[0117] In some implementations, the first signal is associated with the second signal, which can be understood as the transmission resource of the first signal being determined based on the transmission resource of the second signal. In other implementations, the first signal is associated with the second signal, which can be understood as the first signal and the second signal having a QCL relationship, or in other words, the beam direction of the first signal is the same as the beam direction of the second signal. In other implementations, the first signal is associated with the second signal, which can be understood as the first signal and the second signal having the same index. In other implementations, the first signal is associated with the second signal, which can be understood as the first signal and the second signal having the same index can have a QCL relationship.

[0118] In some implementations, the second signal may include one or more of: SSB; SSB burst set; PSS / SSS in SSB.

[0119] In some implementations, the first signal may include an LP-SS or an LP-SS burst set, where an LP-SS burst set may include one or more LP-SSs. In some implementations, each LP-SS in the LP-SS burst set may be associated with a beam, and the LP-SS burst set may be used to measure the beam.

[0120] In some implementations, during beam measurement based on a first signal, first signals transmitted via different beams may explicitly or implicitly carry the first signal's index. For example, if the index is carried explicitly, the first signal and the first signal's index may be transmitted simultaneously via the corresponding beam. For example, if the index is carried implicitly, the first signals on different beams use different synchronization sequences, where different sequences correspond to different indexes.

[0121] In the embodiments of the present application, there is no limitation on the method for generating the synchronization sequence. For example, the synchronization sequences of the first signals corresponding to multiple beams can be generated based on the same synchronization sequence. For example, a synchronization sequence can be cyclically shifted or scrambled to generate multiple different synchronization sequences. Of course, in the embodiments of the present application, the different synchronization sequences can be completely different sequences.

[0122] In the embodiments of the present application, the combination of the first signal and the second signal is not limited. In some implementations, the first signal may be LP-SS and the second signal may be SSB. Accordingly, the transmission resources of the LP-SS may be determined based on the transmission resources of the SSB. In other implementations, the first signal may include multiple signals and the second signal may be an SSB burst set. Accordingly, the transmission resources of the multiple signals may be determined based on the transmission resources of the SSB burst set. In other implementations, the first signal may include LP-SS and the second signal may be an SSB burst set. Accordingly, the transmission resources of the LP-SS may be determined based on the transmission resources of a certain SSB in the SSB burst set, where the transmission resources of a certain SSB may be, for example, the first SSB in the SSB burst set. In other implementations, the first signal may be LP-SS and the second signal may be the PSS / SSS in the SSB. Accordingly, the transmission resources of the LP-SS may be determined based on the transmission resources of the PSS / SSS in the SSB.

[0123] In some implementations, the second signal is an SSB burst set, the first signal includes multiple signals, and the number of the multiple signals is the same as the number of SSBs in the SSB burst set. For example, if the first signal includes multiple LP-SSs, the number of LP-SSs included in the first signal can be the same as the number of SSBs in the SSB burst set.

[0124] In some implementations, the second signal is an SSB burst set, and the first signal includes multiple signals, wherein the multiple SSBs in the SSB burst set correspond one-to-one to the multiple signals, and the multiple SSBs have a QCL relationship with the corresponding first signal, or in other words, the multiple SSBs and the corresponding first signal are sent through a beam.

[0125] In some implementations, the second signal is an SSB burst set, the first signal includes multiple signals, and the number of SSBs in the SSB burst set and the number of the multiple signals are both the same as the number of beams supported by the terminal device. Of course, in the embodiment of the present application, the beams participating in the measurement may be some of the beams supported by the terminal device. Therefore, the number of SSBs in the SSB burst set and the number of the multiple signals are both the same as the number of beams participating in the measurement.

[0126] In some scenarios, the first signal may include multiple signals, and the intervals between two adjacent signals in the time domain among the multiple signals may be the same, which helps to simplify the complexity of transmitting the first signal. Of course, in embodiments of the present application, the intervals between two adjacent signals in the time domain among the multiple signals may be partially or completely different, which helps to increase the flexibility of transmitting the first signal.

[0127] The above describes the first signal and the second signal in the embodiment of the present application. The following describes the transmission resources of the first signal and the transmission resources of the second signal in the embodiment of the present application.

[0128] In some implementations, the transmission resources of the first signal and the transmission resources of the second signal partially or completely overlap in the time domain. Of course, in the embodiment of the present application, the transmission resources of the first signal and the transmission resources of the second signal do not overlap in the time domain.

[0129] In some implementations, the transmission resources of the first signal and the transmission resources of the second signal completely overlap in the time domain. This can be understood as meaning that the time domain resources occupied by the first signal completely overlap with the time domain resources occupied by the second signal, or in other words, the time domain resources occupied by the first signal and the time domain resources occupied by the second signal are the same. FIG. 7 is described below.

[0130] In some other implementations, the transmission resources of the first signal and the transmission resources of the second signal partially overlap in the time domain. This can be understood as the time domain resources occupied by the first signal partially overlapping with the time domain resources occupied by the second signal, or in other words, part of the time domain resources occupied by the first signal are also the time domain resources occupied by the second signal. Figures 8 and 9 are described below.

[0131] In some implementations, the transmission resource of the first signal may be determined based on the transmission resource of the second signal and a first parameter, where the first parameter is used to indicate a time domain interval between the transmission resource of the first signal and the transmission resource of the second signal.

[0132] In the embodiment of the present application, the above-mentioned time domain interval is not limited. In some implementations, the first parameter is used to indicate the time domain interval between the starting position of the transmission resource of the first signal in the time domain and the starting position of the transmission resource of the second signal in the time domain, for example, the first parameter is used to indicate the time domain interval between the starting symbol of the first signal and the starting symbol of the second signal. In other implementations, the first parameter is used to indicate the time domain interval between the ending position of the transmission resource of the first signal in the time domain and the ending position of the transmission resource of the second signal in the time domain. Of course, in the embodiment of the present application, the first parameter is used to indicate the time domain interval between the starting position of the transmission resource of the first signal in the time domain and the ending position of the transmission resource of the second signal in the time domain, or, the first parameter is used to indicate the time domain interval between the ending position of the transmission resource of the first signal in the time domain and the starting position of the transmission resource of the second signal in the time domain.

[0133] In addition, in the embodiments of the present application, the implementation of the above-mentioned time domain interval is not limited. In some implementations, the time interval can be represented by a time domain offset value, which is described below in conjunction with Figure 11. In other implementations, the time interval can be represented by a time period. In still other implementations, the time interval can be represented by the number of time domain resources.

[0134] In some implementations, the first parameter is used to indicate the time interval between a frame carrying the first signal and a frame carrying the second signal; and / or the time interval in the time domain between a transmission resource of the first signal and a target position of the frame carrying the first signal.

[0135] Taking the example where the first parameter is used to indicate the time interval between a frame carrying a first signal and a frame carrying a second signal, the time interval may be referred to as an "interframe interval".

[0136] In some implementations, the first signal may be carried in one or more frames. In this case, the frame carrying the first signal associated with the first parameter may be the earliest frame carrying the first signal in the time domain, that is, the start frame of the first signal. Of course, in an embodiment of the present application, the frame carrying the first signal associated with the first parameter may be the latest frame carrying the first signal in the time domain, that is, the end frame of the first signal. Alternatively, the frame carrying the first signal associated with the first parameter may be any frame carrying the first signal in the time domain.

[0137] In other implementations, the second signal may be carried in one or more frames. In this case, the frame carrying the second signal associated with the first parameter may be the earliest frame carrying the second signal in the time domain, that is, the starting frame of the second signal. Of course, in an embodiment of the present application, the frame carrying the second signal associated with the first parameter may be the latest frame carrying the second signal in the time domain, that is, the ending frame of the second signal. Alternatively, the frame carrying the second signal associated with the first parameter may be any frame carrying the second signal in the time domain.

[0138] In the embodiments of the present application, there is no limitation on the implementation of the inter-frame interval. In some implementations, the inter-frame interval may refer to the time interval between the starting position of the frame carrying the first signal and the starting position of the frame carrying the second signal. In other implementations, the inter-frame interval may refer to the time interval between the starting position of the frame carrying the first signal and the ending position of the frame carrying the second signal. In other implementations, the inter-frame interval may refer to the time interval between the ending position of the frame carrying the first signal and the starting position of the frame carrying the second signal. In other implementations, the inter-frame interval may refer to the time interval between the ending position of the frame carrying the first signal and the ending position of the frame carrying the second signal.

[0139] Taking the example of the first parameter being used to indicate the time interval between the transmission resource of the first signal and the target position of the frame carrying the first signal, the time interval may be referred to as an "intra-frame interval".

[0140] In the embodiments of the present application, the target position is not specifically limited. In some implementations, the target position may be the starting position of the frame carrying the first signal. In other implementations, the target position may be the ending position of the frame carrying the first signal. Of course, in the embodiments of the present application, the target position may be any position in the frame carrying the first signal.

[0141] In the embodiments of the present application, the transmission resource of the first signal is not specifically limited. In some implementations, the transmission resource of the first signal may be the starting time domain position of the transmission resource of the first signal. In other implementations, the transmission resource of the first signal may be the ending time domain position of the transmission resource of the first signal. Of course, in the embodiments of the present application, the transmission resource of the first signal may be any position of the transmission resource of the first signal.

[0142] In the embodiment of the present application, the above-mentioned "intra-frame interval" and "inter-frame interval" can be indicated by different parameters, that is, the first parameter can include multiple parameters to indicate the "intra-frame interval" and "inter-frame interval" respectively. For example, the first parameter can include two parameters, one of which indicates the "intra-frame interval" and the other parameter indicates the "inter-frame interval". Of course, in the embodiment of the present application, the above-mentioned "intra-frame interval" and "inter-frame interval" can be indicated by one parameter, for example, the parameter can be an index of the parameter combination of the "intra-frame interval" and the "inter-frame interval".

[0143] In some implementations, if the time domain resources occupied by the first signal partially or completely overlap with the time domain resources occupied by the second signal, the frequency domain resources occupied by the first signal do not overlap with the frequency domain resources occupied by the second signal, which helps to distinguish the first signal from the second signal. Of course, in an embodiment of the present application, if the time domain resources occupied by the first signal do not overlap with the time domain resources occupied by the second signal, the frequency domain resources occupied by the first signal may overlap with the frequency domain resources occupied by the second signal to simplify the configuration process of the frequency domain resources occupied by the second signal.

[0144] In the embodiment of the present application, there is no limitation on the method for determining the frequency domain resources occupied by the first signal. In some implementations, the frequency domain resources occupied by the first signal can be determined based on the frequency domain resources occupied by the second signal. For example, the frequency domain resources occupied by the first signal can be determined after offsetting the frequency domain offset value on the basis of the frequency domain resources occupied by the second signal, wherein the frequency domain offset value can be predefined, preconfigured, or configured by the network device. For another example, the frequency domain resources occupied by the first signal can be the same as the frequency domain resources occupied by the second signal. Of course, in the embodiment of the present application, the frequency domain resources occupied by the first signal can be configured separately by the network device.

[0145] In some implementations, the number of time domain resources occupied by the first signal is the same as the number of time domain resources occupied by the second signal, which helps to simplify the complexity of measurements based on the first signal and the second signal. For example, both the first signal and the second signal can be used for beam measurement. In an embodiment of the present application, the first signal and the second signal transmitted through the same time domain resources are both used to measure a certain beam, and the receiving end does not need to distinguish between the first signal and the second signal in terms of the number of time domain resources, which helps to simplify the complexity of measurements of the first signal and the second signal. Of course, in an embodiment of the present application, the number of time domain resources occupied by the first signal can be different from the number of time domain resources occupied by the second signal, which helps to improve the flexibility of transmitting the first signal. For example, the number of time domain resources occupied by the first signal can be greater than the number of time domain resources occupied by the second signal. Taking the number of symbols occupied by the second signal as 4, the number of symbols occupied by the first signal can be greater than 4.

[0146] In an embodiment of the present application, the number of time domain resources occupied by the first signal (or the length of the time domain resources occupied by the first signal) can be determined by one or more of the following: predefined information, preconfigured information, and configuration information of the network device.

[0147] In the embodiment of the present application, the first signal may be transmitted periodically. In some implementations, the transmission period of the first signal may be the same as the transmission period of the second signal to simplify the transmission method of the first signal.

[0148] In other implementations, the transmission period of the first signal may be different from the transmission period of the second signal to increase the flexibility of the first signal transmission. For example, the transmission period of the first signal may be greater than the transmission period of the second signal to reduce the frequency with which the terminal device receives the first signal, thereby helping to reduce the power consumption required by the terminal device to receive the first signal. Of course, in the embodiments of the present application, the transmission period of the first signal may be greater than the transmission period of the second signal.

[0149] In some implementations, the transmission period of the first signal may be an integer multiple of the transmission period of the second signal. For example, the first signal is an LP-SS burst set, the second signal is an SSB burst set, and the transmission period of the LP-SS burst set is T LP-SS , the transmission period of SSB burst set is T SSB , accordingly, in T LP-SS There are N SSB burst sets in the time domain resources, where N = T LP-S / T SSB The following will be introduced in conjunction with Figures 8 and 9, and for the sake of brevity, no further details will be given here.

[0150] In an embodiment of the present application, the transmission period of the first signal may be determined by one or more of the following: predefined information, preconfigured information, and configuration information of the network device. Taking the case where the transmission period of the first signal is determined based on the configuration information of the network device as an example, the network device may configure the transmission period of the first signal by using the LPSS period ("LPSS-periodicityServingCell") parameter in the serving cell in the configuration information.

[0151] As described above, the transmission resources of the first signal can be determined based on the transmission resources of the associated second signal. In the embodiments of the present application, the method for determining the second signal associated with the first signal is not limited. In some implementations, the second signal associated with the first signal can be determined based on predefined information and / or configuration information sent by the network device.

[0152] In some implementations, the predefined information and / or configuration information is used to indicate an index of the second signal. For example, the predefined information and / or configuration information indicates that the second signal is the i-th SSB burst set in a transmission period of the LP-SS, where i is a positive integer greater than or equal to 0.

[0153] In some other implementations, the predefined information and / or configuration information is used to indicate the relative position between the transmission resources of the second signal and the transmission resources of the first signal within the transmission period of the first signal.

[0154] In some scenarios, the parameter used to configure the relative position may be referred to as LPSS-PositionsInPeriodicity.

[0155] In the embodiments of the present application, the implementation of the above relative position is not limited. In some implementations, the relative position can be represented by a time interval, that is, the time interval between the transmission resource of the first signal and the transmission resource of the second signal in the LP-SS period. In other implementations, the relative position can be indicated by the nth second signal in the transmission period of the first signal, n = 1, 2, ..., N, where N is the total number of second signals transmitted in the transmission period of the first signal. For example, in T LP-SS There are N time domain resources of SSB burst sets in the memory, wherein the second signal is LP-SS The nth SSB burst set within .

[0156] For ease of understanding, the following describes the predefined information and / or preconfigured information used to indicate the second signal in an embodiment of the present application in conjunction with Table 2. As shown in Table 2, the predefined information and / or preconfigured information may include parameters "LPSS-periodicityServingCell" and "LPSS-PositionsInPeriodicity". Among them, the parameter "LPSS-periodicityServingCell" is used to indicate the transmission period of the first signal, and the optional values ​​of the transmission period include 320ms, 640ms, 960ms, and 1280ms. The parameter "LPSS-PositionsInPeriodicity" is used to indicate that the second signal associated with the first signal in the transmission period of the first signal is the nth second signal, and the optional values ​​of n include 1, 2, ..., N.

[0157] Table 2

[0158] For ease of understanding, the following describes a scheme for determining transmission resources for the first signal in accordance with an embodiment of the present application, in conjunction with Figures 7 to 11. Figures 7 to 9 illustrate the example where the number of time domain resources for the first signal is the same as the number of time domain resources for the second signal, and Figures 10A to 11 illustrate the example where the number of time domain resources for the first signal is greater than the number of time domain resources for the second signal.

[0159] As shown in Figure 7, assuming that the first signal is LP-SS and the second signal is SSB, the frequency domain resources of the LP-SS and SSB do not overlap. The LP-SS transmission period is the same as the SSB transmission period, and the time domain resources of the first signal are the same as the time domain resources of the second signal. In other words, the time domain resources of the first signal and the second signal completely overlap.

[0160] As shown in Figure 8 , assuming the first signal is LP-SS and the second signal is SSB, the frequency domain resources of the LP-SS and the frequency domain resources of the SSB do not overlap. The LP-SS transmission period is 320 ms, and the SSB transmission period is 80 ms. In other words, the LP-SS transmission period is four times the SSB transmission period, and the LP-SS transmission period includes four time domain resources for transmitting SSBs. Furthermore, within the LP-SS transmission period, the LP-SS transmission resources and the transmission resources of the first SSB have the same time domain location. In other words, within the LP-SS transmission period, the LP-SS transmission resources and the time domain resources of the first SSB are the same. However, within the LP-SS transmission period, the time domain resources of other SSBs other than the time domain resources of the first SSB do not transmit LP-SS. In other words, the time domain resources of the LP-SS and the time domain resources of the SSB partially overlap.

[0161] Accordingly, the first SSB may be determined by the above parameter “LPSS-periodicityServingCell”, and the transmission period of the LP-SS may be determined by the parameter “LPSS-periodicityServingCell”.

[0162] As shown in Figure 9, assuming the first signal is LP-SS and the second signal is SSB, the frequency domain resources of the LP-SS and the frequency domain resources of the SSB do not overlap. The LP-SS transmission period is 320 ms, and the SSB transmission period is 80 ms. This means that the LP-SS transmission period is four times the SSB transmission period, and the LP-SS transmission period includes four time domain resources for transmitting the SSB. Furthermore, within the LP-SS transmission period, the LP-SS transmission resources and the second SSB transmission resources have the same time domain location. In other words, within the LP-SS transmission period, the LP-SS transmission resources and the second SSB transmission resources have the same time domain location. However, within the LP-SS transmission period, the time domain resources of the other SSBs other than the first SSB do not transmit the LP-SS. This means that the LP-SS time domain resources partially overlap with the SSB time domain resources.

[0163] Accordingly, the second SSB may be determined by the above parameter “LPSS-periodicityServingCell”, and the transmission period of the LP-SS may be determined by the parameter “LPSS-periodicityServingCell”.

[0164] As shown in Figure 10A , assuming the first signal is LP-SS and the second signal is SSB, the frequency domain resources of the LP-SS and SSB do not overlap. The number of time domain resources of the SSB is four, while the number of time domain resources of the LP-SS is greater than four. The transmission period of the LP-SS is 320 ms, and the transmission period of the SSB is 80 ms. In other words, the transmission period of the LP-SS is four times the transmission period of the SSB, and the LP-SS transmission period includes four time domain resources for transmitting the SSB. In addition, the time domain position of the LP-SS transmission resources within the LP-SS transmission period is determined based on the time domain resources of the first SSB. In other words, the LP-SS is associated with the first SSB within the LP-SS transmission period.

[0165] As shown in Figure 10B , assuming the first signal is LP-SS and the second signal is SSB, the frequency domain resources of the LP-SS and SSB do not overlap. The number of time domain resources of the SSB is four, while the number of time domain resources of the LP-SS is greater than four. The transmission period of the LP-SS is 320 ms, and the transmission period of the SSB is 80 ms. In other words, the transmission period of the LP-SS is four times that of the SSB, and the LP-SS transmission period includes four time domain resources for transmitting the SSB. In addition, the time domain position of the LP-SS transmission resources within the LP-SS transmission period is determined based on the time domain resources of the third SSB. In other words, the LP-SS is associated with the third SSB within the LP-SS transmission period.

[0166] As shown in Figure 11, assuming that the first signal is LP-SS and the second signal is SSB, the frequency domain resources of LP-SS do not overlap with the frequency domain resources of SSB. The first parameter is used to indicate the time offset value T between the transmission resources of the first LP-SS and the transmission resources of the first SSB in the time domain. offset That is to say, the time offset between the starting time domain position of the first LP-SS transmission resource and the starting time domain position of the first SSB transmission resource is T offset .

[0167] It should be noted that, taking the example of the first signal being LP-SS and the second signal being SSB, the relationship between the transmission resources of the first signal and the transmission resources of the second signal in the embodiments of the present application is described in conjunction with Figures 7 to 11. The schemes described in Figures 7 to 11 are also applicable to the case where the first signal is an LP-SS burst set and the second signal is an SSB burst set. In this case, the time domain resources of the first signal can be understood as the time domain resources of the LP-SS burst set, and the time domain resources of the second signal can be understood as the time domain resources of the SSB burst set.

[0168] Embodiment 2: The first information includes configuration information of transmission resources of the first signal.

[0169] That is to say, the transmission resource of the first signal can be independently configured through the configuration information, which helps to improve the flexibility of configuring the transmission resource of the first signal.

[0170] In the embodiment of the present application, there is no limitation on the transmission method of the configuration information. In some implementations, the configuration information can be carried in RRC signaling.

[0171] In some implementations, the above configuration information is used to configure one or more of the following: the time domain length of the first signal; the transmission period of the first signal; the time domain position of the first signal in the first frame; the number of first signals transmitted in the first frame; and the subcarrier spacing of the first signal.

[0172] Taking the configuration information used to configure the time domain length of the first signal as an example, the time domain length of the first signal can be indicated by the number of time domain resources occupied by the first signal. Of course, in the embodiment of the present application, the time domain length of the first signal can be represented by the duration corresponding to the time domain resources occupied by the first signal.

[0173] Take the configuration information used to configure the transmission period of the first signal as an example, wherein the transmission period of the first signal can refer to the above introduction.

[0174] Taking the configuration information used to configure the time domain position of the first signal in the first frame as an example, in some scenarios, the parameter used to indicate the time domain position of the first signal in the first frame may be called "LPSS-positionInPeriodicity".

[0175] In some implementations, the configuration information may directly configure the time domain position of the first signal within the first frame.

[0176] In the embodiments of the present application, the time domain position of the first signal configured by the configuration information within the first frame is not specifically limited. In some implementations, the configuration information may configure the starting time domain position of the first signal within the first frame. For example, the configuration information may indicate the starting symbol of the first signal within the first frame. In other implementations, the configuration information may be used to configure the ending time domain position of the first signal within the first frame. For example, the configuration information may indicate the ending symbol of the first signal within the first frame.

[0177] In other implementations, the configuration information may hierarchically indicate the time domain position of the first signal within the first frame. For example, the configuration information may indicate the subframe in the first frame that carries the first signal and / or the symbol of the first signal carried in the subframe that carries the first signal. For another example, the configuration information may indicate the subframe in the first frame that carries the first signal, the time slot in the subframe that carries the first signal, and the symbol of the first signal carried in the time slot. This is described below in conjunction with Figure 13.

[0178] In the embodiments of the present application, the number of subframes carrying the first signal is not limited. In some implementations, the number of subframes carrying the first signal may be multiple, in which case the configuration information may be used to indicate the multiple subframes carrying the first signal. For another example, the number of subframes carrying the first signal may be one, in which case the configuration information may be used to indicate the one subframe carrying the first signal.

[0179] In the embodiments of the present application, the manner in which the configuration information indicates the symbol carrying the first signal is not limited. In some implementations, the configuration information may indicate the time domain interval between the starting time domain position of the subframe carrying the first signal and the starting symbol carrying the first signal. In other implementations, the configuration information may indicate the time domain interval between the starting time domain position of the subframe carrying the first signal and the ending symbol carrying the first signal.

[0180] In the embodiment of the present application, the number of time domain positions of the first signal within the first frame is not limited. For example, the number of time domain positions of the first signal within the first frame may be multiple, in which case the configuration information may be used to configure multiple time domain positions of the first signal within the first frame. For another example, the number of time domain positions of the first signal within the first frame may be one, in which case the configuration information may be used to configure one time domain position of the first signal within the first frame.

[0181] It should be noted that, in addition to being configured by configuration information, the time domain position of the first signal within the first frame may also be pre-agreed or pre-configured. For example, it may be pre-agreed that a frame may include multiple time domain resources for transmitting the first signal. For another example, it may be pre-agreed that a frame may include only one time domain resource for transmitting the first signal.

[0182] Taking the example of configuration information used to configure the number of first signals transmitted in the first frame, as described above, if multiple first signals are transmitted in the first frame, the configuration information may indicate the time domain positions of the multiple first signals in the first frame. In this case, it can be understood that the configuration information indirectly indicates the number of first signals transmitted in the first frame. Of course, in the embodiment of the present application, the configuration information directly indicates the number of first signals transmitted in the first frame.

[0183] Taking the configuration information used to indicate the subcarrier spacing of the first signal as an example, the parameter used to indicate the subcarrier spacing of the first signal can be called "LPSS-SubcarrierSpacing".

[0184] It should be noted that, as mentioned above, the first signal can be used for LR synchronization. Accordingly, the first frame mentioned above can also be called a "LR synchronization frame".

[0185] The following describes, in conjunction with Figure 12, a scheme for the network device to configure the transmission resources of the first signal for the terminal device in an embodiment of the present application. Referring to Figure 12, in step S1210, the network device sends configuration information to the terminal device, wherein the configuration information is carried in RRC signaling, and the configuration information includes one or more of the following parameters: LPSS-periodicityServingCell, used to indicate the transmission period of LP-SS; LPSS-positionInPeriodicity, used to indicate the position of the LR synchronization frame configured within the transmission period of LP-SS; LPSS-SubcarrierSpacing, used to indicate the subcarrier spacing of LP-SS; LPSS-Duration, used to indicate the time domain length of LP-SS; LPSS-timeoffset, used to indicate the time domain position of LPSS within the LR synchronization frame, wherein the time domain offset can be one or more, that is, corresponding to one or more time domain positions.

[0186] It should be noted that the first signal configured in Example 2 may be associated with the second signal, and the manner of associating the first signal with the second signal may refer to the relevant description in Example 1. In addition, the transmission manner of the first signal and the second signal described in Example 1 (for example, the transmission period of the first signal and the transmission period of the second signal, and / or the transmission resource of the first signal and the transmission resource of the second signal) may also be applied to Example 2, and for the sake of brevity, they will not be described in detail here.

[0187] In some implementations, the transmission period of the first signal may be determined based on one or more of the following parameters: the frame number of the SFN carrying the first signal; the length of the transmission period of the first signal; and the time domain position of the transmission period of the first signal within the frame.

[0188] The time domain position of the transmission period of the first signal within the frame may include the time domain position of the starting position of the transmission period of the first signal within the frame, or the time domain position of the ending position of the transmission period of the first signal within the frame.

[0189] In addition, the frame number of the SFN carrying the first signal and the length of the transmission period of the first signal can be found in the above introduction, and for the sake of brevity, they are not repeated here.

[0190] For example, nSFN represents the frame number of SFN, the transmission period of the first signal is x, and y' represents the starting position of the transmission period of the first signal, then y'=nSFN mod x.

[0191] In some implementations, the first frame may be determined based on the length of the first signal transmission period and the SFN frame number. For example, nSFN represents the SFN frame number, the length of the first signal transmission period is x, and y represents the index or offset value of the frame carrying the first signal within the first signal transmission period, then y = nSFN mod x. The parameter y may take one or more values.

[0192] The following describes a method for determining the transmission resources of LP-SS in an embodiment of the present application in conjunction with Figure 13. Referring to Figure 13, according to the formula y`=nSFN mod x, the frame carrying the first signal is determined to be Frame#x+2, where nSFN represents the frame number of SFN, the value of x is equal to the time domain length of the LP-SS period, and y` represents the index / time domain offset value of the frame in which LP-SS is located within the LP-SS transmission period. Afterwards, the time domain resources for carrying LP-SS are determined. Assume that the network device configures the subframe carrying LP-SS to be Subframe#3 through configuration information, and configures the time slot carrying LP-SS in the subframe to be Slot#2, and the symbols carrying LP-SS in the time slot are symbols 2 to 5.

The device embodiment of the present application is described in detail below in conjunction with Figures 14 to 16.
