[0048] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0049] 1. Low power wake-up receiver (LP WUR).

[0050] The basic working principle of LP WUR is that the receiver includes a first module and a second module. The first module is the main communication module, used to receive and transmit communication data from the transmitter. The second module is a low-power module, used to receive the low-power wake-up signal (LP-WUS) and the low-power synchronization signal (LP-SS) sent by the transmitter. The LP-WUS wake-up signal is used to wake up the receiver's main communication module, and the LP-SS provides time reference information and other information for receiving the LP-WUS wake-up signal. For example, it is used for radio resource management (RRM) measurements of the serving cell, and can also provide wake-up link management, such as determining whether to activate or deactivate LP-WUR and turn off the main receiver (MR) based on the measurement results. As shown in Figure 2, the first module is always in the off state when it is not woken up by the second module, and does not send or receive data. When downlink data arrives, the second module detects the wake-up signal sent by the transmitter, and if the wake-up signal contains information about the terminal, the second module triggers the first module to switch from the off state to the working state to receive and transmit data. The second module can be turned on continuously or intermittently. When the second module is turned on, it can receive low-power wake-up signals and low-power synchronization signals.

[0051] II. Low-power wake-up signal.

[0052] Low-power wake-up signals are typically simple on-off keying (OOK) signals, as shown in Figure 3. In this way, the receiver can obtain the wake-up notification through simple energy detection and subsequent possible sequence detection and recognition processes.

[0053] Since NR systems commonly employ Orthogonal Frequency Division Multiplexing (OFDM) signal modulation, OOK signals can be generated using OFDM signal generation methods. For example, transmitting or not transmitting an OFDM-modulated sequence represents ON / OFF in the time domain. OOK signals can be received using low-power receivers.

[0054] Furthermore, the OFDM modulation sequence in the ON modulation can carry information through different sequences, such as two sequences representing 0 and 1 information respectively, or four sequences representing 00, 01, 10, and 11 information respectively.

[0055] Optionally, in the waveform or modulation scheme of the on / off key control OOK superimposed orthogonal frequency division multiplexing OFDM (OOK with overlaid OFDM sequence), as shown in Figure 4, part of the information is modulated by OOK, and the other part of the information is carried by the ON level OFDM sequence.

[0056] III. NR SSB.

[0057] In an NR system, as shown in Figure 5, the SSB typically includes the Primary Synchronization Signal (PSS), the Secondary Synchronization Signal (SSS), the Physical Broadcast Channel (PBCH), and the Physical Broadcast Channel Demodulation Reference Signal (DMRS).

[0058] The main functions of PSS and SSS are to achieve symbol-level synchronization and to complete the Physical-layer Cell Identity (PCI) process. The determination of the PBCH is as follows. As shown in Figure 6, the PBCH contains the cell's Master Information Block (MIB) and some other information. The PBCH-DMRS serves as the PBCH demodulation reference signal and also contains some SSB index information (the lower three bits).

[0059] The synchronization signal block detection method, apparatus, and terminal provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0060] Referring to FIG7, an embodiment of this application provides a synchronization signal block detection method, as shown in FIG7, the synchronization signal block detection method includes:

[0061] Step 101: The terminal detects the first synchronization signal block on the first resource and obtains the target synchronization information;

[0062] Step 102: The terminal determines a third resource from the second resource based on the target synchronization information, wherein the second resource is the resource associated with the second synchronization signal block;

[0063] Step 103: The terminal detects the second synchronization signal block based on the third resource;

[0064] The first synchronization signal block adopts any of the following waveforms or modulation methods: Amplitude Shift Keying (ASK); Frequency Shift Keying (FSK); On / Off Keying (OOK) superimposed Orthogonal Frequency Division Multiplexing (OFDM); OFDM.

[0065] The target synchronization information may include relevant information about the detected first synchronization signal block.

[0066] In this embodiment of the application, the first synchronization signal block can be understood as a low-power synchronization signal block, and the second synchronization signal block can be understood as a synchronization signal block used to assist the terminal in accessing the network, such as an SSB.

[0067] Optionally, in some embodiments, the second synchronization signal block can be understood as a non-low-power synchronization signal block or a non-blind detection synchronization signal block.

[0068] In addition, the waveform or modulation scheme of the first synchronization signal block can be predefined by network configuration or protocol.

[0069] In addition, the waveform or modulation scheme of the second synchronization signal block can be predefined by network configuration or protocol.

[0070] In one implementation, the detection power consumption of the first synchronization signal block is less than that of the second synchronization signal block.

[0071] In one implementation, the detection time of the first synchronization signal block is shorter than the detection time of the second synchronization signal block.

[0072] In one implementation, the third resource can be a portion of the second resource. The terminal can determine the third resource from the second resource based on the target synchronization information, and detect the second synchronization signal block on the third resource, thereby narrowing the time-domain and frequency-domain detection range of the second synchronization signal block.

[0073] Furthermore, the first, second, or third resource can be represented as a resource set or a resource list, etc., and this embodiment does not limit this. For example, the first resource can be represented by a first resource set, the second resource can be represented by a second resource set, and the third resource can be represented by a third resource set.

[0074] In one implementation, a first resource is represented by a first resource set, a second resource by a second resource set, and a third resource by a third resource set. The terminal can detect a first synchronization signal block in the first resource set and obtain target synchronization information. The target synchronization information includes information about one or more detected first synchronization signal blocks. The terminal can determine a third resource set based on the target synchronization information and the second resource set. The terminal can detect a second synchronization signal block based on the third resource set.

[0075] Optionally, the first resource is configured by the network or predefined by the protocol; or

[0076] The second resource is configured by the network or predefined by the protocol.

[0077] The first resource may include at least one of time-domain resources and frequency-domain resources; the second resource may include at least one of time-domain resources and frequency-domain resources.

[0078] It is important to note that network energy conservation is crucial for environmental sustainability, reducing environmental impacts (such as greenhouse gas emissions), and saving operating costs. Currently, most energy consumption comes from wireless access networks, particularly from active antenna units (AAUs), with data centers and fiber optic transmission accounting for a smaller share. Wireless access power consumption can be divided into dynamic and static components: the dynamic component consumes energy only during data transmission / reception, while the static component continuously consumes energy to maintain the operation of the wireless access equipment, even when data transmission / reception is not in progress. Minimizing the power consumption of the static component is a key technical challenge that needs to be addressed.

[0079] Currently, synchronization signal blocks (such as SSB) use OFDM waveforms for periodic transmission. The initial access period of SSB is 20ms. The short period results in high network energy consumption and load overhead, making it impossible to effectively achieve network energy saving.

[0080] In related technologies, increasing the synchronization signal block period (such as the transmission period of SSB) can effectively improve network energy saving. However, increasing the synchronization signal block period will increase the initial access latency of the terminal and increase the complexity and power consumption of the terminal in detecting the synchronization signal block. In the embodiments of this application, by designing a first synchronization signal block, the terminal can reduce the time-domain and frequency-domain detection range of the second synchronization signal block by detecting the first synchronization signal block first, thereby reducing the initial access latency of the terminal and reducing the complexity and power consumption of the terminal in detecting the synchronization signal block.

[0081] In this embodiment, the terminal detects a first synchronization signal block on a first resource to obtain target synchronization information; the terminal determines a third resource in a second resource based on the target synchronization information, the second resource being a resource associated with the second synchronization signal block; the terminal detects the second synchronization signal block based on the third resource; wherein the first synchronization signal block adopts any of the following waveforms or modulation schemes: Amplitude Shift Keying (ASK); Frequency Shift Keying (FSK); On / Off Keying (OOK) superimposed with Orthogonal Frequency Division Multiplexing (OFDM); OFDM. Thus, by detecting the first synchronization signal block to obtain target synchronization information, and using the target synchronization information to detect the second synchronization signal block, the detection range of the second synchronization signal block can be narrowed, thereby reducing the power consumption of the terminal in detecting the SSB and reducing the time for the terminal to detect the SSB during the initial cell search, thereby reducing the latency of the terminal accessing the cell.

[0082] Optionally, the frequency domain resources in the first resource include a first frequency point, which includes candidate frequency points for the transmission of the first synchronization signal block; or, the time domain resources in the first resource include time domain resources determined by repeating in the time domain by a first time window with a first cycle length.

[0083] or

[0084] The frequency domain resources in the second resource include a second frequency point, which includes a candidate frequency point for the transmission of the second synchronization signal block; or, the time domain resources in the second resource include time domain resources determined by the second time window repeating in the time domain with a second period length.

[0085] Wherein, the length of the first period is less than or equal to the length of the second period.

[0086] The number of first frequency points and the number of second frequency points can be multiple. The first or second frequency points can be represented as a set of frequency points or a list of frequency points, etc., and this embodiment does not limit this. For example, a first frequency point can be represented by a set of first frequency points, and a second frequency point can be represented by a set of second frequency points.

[0087] The first period length can be the transmission period length of the first synchronization signal block. The second period length can be the transmission period length of the second synchronization signal block.

[0088] In addition, the time domain location of the first time window can be predefined by network configuration or protocol; or the time domain location of the first time window can be determined by the terminal according to network instructions.

[0089] In addition, the time domain location of the second time window can be predefined by network configuration or protocol; or the time domain location of the second time window can be determined by the terminal according to network instructions.

[0090] In one embodiment, taking the first resource as represented by a first resource set, the second resource as represented by a second resource set, the third resource as represented by a third resource set, the first frequency point as represented by a first frequency point set, and the second frequency point as represented by a second frequency point set as an example, the frequency domain resources of the first resource set include the first frequency point set, the first frequency point set includes all candidate frequency points for the transmission of the first synchronization signal block, and the time domain resources of the first resource set include a time window that repeats with a first period length;

[0091] The second resource set includes a second frequency point set, which contains all candidate frequency points for the transmission of the second synchronization signal block, and the time domain resources of the second resource set include time windows that repeat with a second period length.

[0092] The third resource set is a subset of the second resource set determined based on the target synchronization information, and the length of the first cycle is not greater than the length of the second cycle.

[0093] Optionally, the first frequency point and the second frequency point satisfy a first condition, which includes any one of the following:

[0094] The first frequency point and the second frequency point do not have the same frequency point, and the number of frequency points of the first frequency point is less than the number of frequency points of the second frequency point;

[0095] The first frequency point and the second frequency point have some frequency points that are the same, and the number of frequency points of the first frequency point is less than the number of frequency points of the second frequency point;

[0096] The first frequency point is the same as the second frequency point.

[0097] Wherein, the first frequency point and the second frequency point are the same can mean that the first frequency point and the second frequency point have all the same frequency points, and the spacing between two adjacent frequency points in the first frequency point is the same as the spacing between two adjacent frequency points in the second frequency point.

[0098] In one implementation, taking the first frequency point as represented by a first frequency point set and the second frequency point as represented by a second frequency point set as an example, the relationship between the first frequency point set and the second frequency point set is any one of the following:

[0099] The candidate frequency points contained in the first frequency point set and the second frequency point set are completely different, and the number of frequency points contained in the first frequency point set is less than the number of frequency points contained in the second frequency point set. The spacing between two adjacent frequency points in the first frequency point set is the same as or different from the spacing between two adjacent frequency points in the second frequency point set.

[0100] Or the candidate frequency points contained in the first frequency point set and the second frequency point set are completely different or partially the same, and the number of frequency points contained in the first frequency point set is less than the number of frequency points contained in the second frequency point set, and the spacing between two adjacent frequency points in the first frequency point set is the same or different from the spacing between two adjacent frequency points in the second frequency point set.

[0101] Alternatively, the first frequency set and the second frequency set contain the same candidate frequency points, and the spacing between two adjacent frequency points in the first frequency set is the same as the spacing between two adjacent frequency points in the second frequency set.

[0102] The frequency points included in the first frequency point set and the frequency points included in the second frequency point set are pre-configured by the network or pre-defined by the protocol.

[0103] Optionally, the first period length is a network configuration or a first duration predefined by the protocol; or, the first period length is a second duration determined by the terminal according to the network instruction.

[0104] or

[0105] The second period length is a network configuration or a third duration predefined by the protocol; or, the second period length is a fourth duration determined by the terminal according to network instructions.

[0106] The network side may implicitly or explicitly indicate a second duration, and the terminal determines the second duration indicated by the network side as the first cycle length. For example, the network side may indicate that the transmission cycle of the first synchronization signal block is a second duration, and the terminal determines the second duration indicated by the network side as the first cycle length. The network side may implicitly or explicitly indicate a fourth duration, and the terminal determines the fourth duration indicated by the network side as the second cycle length. For example, the network side may indicate that the transmission cycle of the second synchronization signal block is a fourth duration, and the terminal determines the fourth duration indicated by the network side as the second cycle length.

[0107] It should be noted that the network can set the first cycle length through configuration or dynamic indication. For example, the network can first be configured with a longer first cycle length, and then dynamically indicated to change it to a shorter first cycle length. The network can also set the second cycle length through configuration or dynamic indication. For example, the network can first be configured with a longer second cycle length, and then dynamically indicated to change it to a shorter second cycle length.

[0108] In one embodiment, the first period length may be a first duration pre-configured by the network or pre-defined by the protocol; or, after the network pre-configures or pre-defines the first duration, the network reconfigures the first duration for the terminal, and the terminal uses the newly configured first duration as the first period length to detect the first synchronization signal block, or the terminal uses the second duration determined according to the network dynamic indication as the first period length to detect the first synchronization signal block.

[0109] In one implementation, the period length of the time-domain resources in the third resource set is the same as the period length of the time-domain resources in the second resource set, both being the second period length. The second period length can be a third duration pre-configured by the network or pre-defined by the protocol; or, after the network pre-configures or pre-defines the third duration, the network reconfigures the third duration for the terminal, and the terminal uses the newly configured third duration as the second period length to detect the second synchronization signal block; or the terminal uses a fourth duration determined according to the network's dynamic indication as the second period length to detect the first synchronization signal block.

[0110] Optionally, the target synchronization information includes at least one of the following:

[0111] The time-domain location information of the detected first synchronization signal block;

[0112] The frequency domain position information of the detected first synchronization signal block;

[0113] The first indication information carried by the detected first synchronization signal block.

[0114] In one embodiment, the time-domain location information of the detected first synchronization signal block includes one or more time-domain locations in the first resource where the first synchronization signal block is detected.

[0115] In one embodiment, the frequency domain location information of the detected first synchronization signal block includes one or more frequency points in the first frequency points where the first synchronization signal block is detected.

[0116] In one embodiment, the terminal can determine the frequency domain resources included in the third resource based on the time domain location information of the first synchronization signal block and the second frequency point; or it can determine the frequency domain resources included in the third resource based on the frequency domain location information of the first synchronization signal block and the second frequency point; or it can determine the frequency domain resources included in the third resource based on the first indication information carried by the first synchronization signal block and the second frequency point.

[0117] It should be understood that the first resource may be a candidate resource of the first synchronization signal block, and the detected time-domain location information or the detected frequency-domain location information of the first synchronization signal block may be used to indicate that the terminal actually detected the resource of the first synchronization signal block.

[0118] Optionally, the terminal determines a third resource from the second resource based on the target synchronization information, including at least one of the following:

[0119] The terminal determines the first frequency domain resource based on the time domain location information of the detected first synchronization signal block and the second frequency point;

[0120] The terminal determines the second frequency domain resource based on the frequency domain location information of the detected first synchronization signal block and the second frequency point;

[0121] The terminal determines the third frequency domain resource based on the first indication information and the second frequency point;

[0122] The third resource includes the first frequency domain resource, the second frequency domain resource, or the third frequency domain resource.

[0123] Optionally, the time-domain location information of the first synchronization signal block is used to indicate at least one set of time-domain transmission locations of the first synchronization signal block contained within a first period length, and each set of time-domain transmission locations is associated with at least one second frequency point;

[0124] The first frequency domain resource includes a second frequency point associated with at least one time domain transmission location set of the first synchronization signal block detected by the terminal.

[0125] For example, the second frequency points included in the frequency domain resources of the second resource can be divided into multiple subsets, such as subset 1, subset 2, ..., subset J, each subset containing at least one candidate frequency point for the transmission of the second synchronization signal block. The terminal can determine the subset of at least one second frequency point associated with the detected time-domain transmission location set of the first synchronization signal block (e.g., transmission location set 1 associated with subset 1, transmission location set 2 associated with subset 2, ..., transmission location set J associated with subset J). The terminal can detect the second synchronization signal block only within the second frequency points contained in the subset associated with the time-domain transmission location sets of one or more successfully detected first synchronization signal blocks.

[0126] In one embodiment, taking the second frequency point as a representation through a set of second frequency points as an example, the method by which the terminal determines the first frequency domain resource based on the time domain location information of the detected first synchronization signal block and the second frequency point is as follows:

[0127] The first synchronization signal block contains at least one time-domain transmission location set within a first cycle length. Each time-domain transmission location set is associated with one or more frequency points in the second frequency point set. The terminal determines the frequency domain resources contained in the third resource based on at least one frequency point in the second frequency point set associated with the detected at least one time-domain transmission location set.

[0128] The time-domain transmission location set identifier within a first cycle length is carried by at least one of a sequence or information block.

[0129] The association between one or more time-domain location sets contained within the first period length and one or more frequency points in the second frequency point set is pre-configured by the network or pre-defined by the protocol.

[0130] Optionally, the identifier of the time-domain transmission location set is indicated by a sequence or information block in the first synchronization signal block.

[0131] Optionally, the association between the time-domain transmission location set and the second frequency point is configured by the network or predefined by the protocol.

[0132] In one embodiment, the terminal can obtain the association relationship between the time-domain transmission location set and the second frequency point; based on the association relationship between the time-domain transmission location set and the second frequency point and at least one time-domain transmission location set of the first synchronization signal block detected by the terminal, the terminal can determine the second frequency point associated with at least one time-domain transmission location set of the first synchronization signal block detected by the terminal in the second resource.

[0133] Optionally, the frequency domain location information of the first synchronization signal block is used to indicate at least one first frequency point, and the third resource includes at least one second frequency point associated with the first frequency point indicated by the frequency domain location information.

[0134] In one implementation, taking the representation of a first frequency point through a first frequency point set and a second frequency point through a second frequency point set as an example, the method by which the terminal determines the second frequency domain resource based on the detected frequency domain location information of the first synchronization signal block and the second frequency point is as follows: Based on one or more frequency points in the first frequency point set included in the frequency domain location information of the first synchronization signal block, determine one or more frequency point information in the associated second frequency point set. The frequency domain resource included in the third resource comprises the frequency points represented by the one or more frequency point information in the associated second frequency point set. The association relationship between one or more frequency points in the first frequency point set and one or more frequency point information in the second frequency point set is pre-configured by the network or pre-defined by the protocol.

[0135] For example, the terminal determines one or more second frequency points associated with the detected first synchronization signal block based on the location of one or more first frequency points. The terminal can detect the second synchronization signal block only at one or more second frequency points associated with the one or more first frequency points of the successfully detected first synchronization signal block.

[0136] In one embodiment, the terminal can obtain the association relationship between the first frequency point and the second frequency point; the terminal can determine at least one second frequency point associated with the first frequency point indicated by the frequency domain location information in the second resource based on the association relationship between the first frequency point and the second frequency point and the first frequency point indicated by the frequency domain location information; the third resource includes at least one second frequency point associated with the first frequency point indicated by the frequency domain location information.

[0137] In one implementation, the association between the first frequency point and the second frequency point is predefined by network configuration or protocol.

[0138] Optionally, the first indication information is used to indicate at least one of the second frequency points, and the third resource includes the second frequency point indicated by the first indication information.

[0139] For example, the first indication information may indicate at least one frequency point index or frequency point identifier of the second frequency point, and the third resource may include the second frequency point represented by the frequency point index or frequency point identifier indicated by the first indication information. The terminal may detect the second synchronization signal block only at the second frequency point represented by the frequency point index or frequency point identifier indicated by the first indication information.

[0140] In one embodiment, taking the second frequency point as represented by a second frequency point set as an example, the method by which the terminal determines the third frequency domain resource based on the first indication information and the second frequency point is as follows: the first indication information includes indication information of one or more frequency point indices in the second frequency point set, and the frequency domain resource included in the third resource includes the frequency point identified by the frequency point index indicated by the first indication information.

[0141] Optionally, the time-domain position represented by the time-domain position information of the first synchronization signal block includes the time-domain start position or the time-domain end position of the first synchronization signal block. The terminal determines the third resource in the second resource based on the target synchronization information, including:

[0142] The terminal determines the target time domain position based on the time domain start position or time domain end position of the first synchronization signal block;

[0143] The terminal determines the target period in the time domain resource of the second resource based on the target time domain location;

[0144] The terminal determines a third time window based on the target period. The starting position of the third time window is the target time domain position within the target period, and the ending position of the third time window is determined based on the target time domain position and the second time domain offset; or, the ending position of the third time window is the ending position of the target period.

[0145] The third resource includes time-domain resources determined by the third time window repeating in the time domain with the second period length.

[0146] Furthermore, the target time-domain position can be the time-domain position obtained by adding a first time-domain offset to the time-domain start position of the first synchronization signal block; or, the target time-domain position can be the time-domain position obtained by adding a first time-domain offset to the time-domain end position of the first synchronization signal block; or, the target time-domain position can be the time-domain start position of the first synchronization signal block; or, the target time-domain position can be the time-domain end position of the first synchronization signal block; etc., this embodiment does not limit this. The first time-domain offset can be configured by the network or predefined by the protocol.

[0147] Optionally, the terminal determines the target time-domain position based on the time-domain start position or time-domain end position of the first synchronization signal block, including:

[0148] The terminal determines the target time domain position based on the first time domain offset and the time domain start position or time domain end position of the first synchronization signal block;

[0149] Wherein, the first time-domain offset is the time-domain offset of the detection range of the second synchronization signal block relative to the first synchronization signal block.

[0150] The target time domain position can be the time domain position obtained by adding the first time domain offset to the time domain start position of the first synchronization signal block; or, the target time domain position can be the time domain position obtained by adding the first time domain offset to the time domain end position of the first synchronization signal block.

[0151] In one embodiment, the target time-domain position can be a first time-domain position. The terminal can determine the first time-domain position based on the time-domain start position of the first synchronization signal block and a predefined first time-domain offset. Based on the first time-domain position, a period (i.e., a target period) of the time-domain resources of the second resource is determined, with the first time-domain position as the start position and the end position of the period as the end position within that period. Alternatively, the first time-domain position is added to the second time-domain offset to obtain a time window of the time-domain resources of the third resource, i.e., a third time window. The time-domain resources included in the third resource include the time-domain resources determined by the third time window repeatedly in the time domain with a second period length. The values ​​of the first time-domain offset and the second time-domain offset are greater than or equal to 0. The first time-domain position can be the time-domain position obtained by adding the first time-domain offset to the time-domain start position of the first synchronization signal block.

[0152] In one embodiment, the target time-domain position can be a second time-domain position. The terminal can determine the second time-domain position based on the time-domain end position of the first synchronization signal block and a predefined first time-domain offset. Based on the second time-domain position, a period (i.e., a target period) of the time-domain resources of the second resource is determined. Within this period, the second time-domain position is used as the starting position, and the end position of the period is used as the ending position. Alternatively, the second time-domain position is added to the second time-domain offset to obtain a time window of the time-domain resources of the third resource, i.e., a third time window. The time-domain resources included in the third resource include the time-domain resources determined by the third time window repeating in the time domain with a second period length. The values ​​of the first time-domain offset and the second time-domain offset are greater than or equal to 0. The second time-domain position can be the time-domain position obtained by adding the first time-domain offset to the time-domain end position of the first synchronization signal block.

[0153] In addition, the units of the first time offset and the second time offset can be symbol length, time slot length or subframe length. The length of the symbol, time slot or subframe can be determined based on the waveform of the first synchronization signal block or the waveform of the second synchronization signal block. The units of the first time offset and the second time offset can also be milliseconds or seconds, etc.

[0154] Optionally, the terminal detects the second synchronization signal block based on the third resource, including any one of the following:

[0155] The terminal receives the second synchronization signal block on the third resource and detects the second synchronization signal block;

[0156] The terminal receives a signal on the second resource and detects the second synchronization signal block in the received signal based on the third resource.

[0157] The terminal may determine the third resource based on the target synchronization information, and then receive and detect the second synchronization signal block in the third resource; or the terminal may receive the second synchronization signal block in the second resource, and after determining the third resource based on the target synchronization information, detect the received second synchronization signal block in the third resource.

[0158] In one embodiment, the terminal receives and detects the second synchronization signal block on the third resource. For example, the terminal detects the second synchronization signal block based on the third resource determined by the acquired target synchronization information in the next time period after detecting the first synchronization signal block and obtaining the target synchronization information. Thus, the terminal receives and detects the second synchronization signal block after determining the third resource, and the reception and detection of the second synchronization signal block are performed in parallel, eliminating the need to store the received signal and reducing storage overhead.

[0159] In one implementation, the terminal receives a signal on the second resource and detects the second synchronization signal block in the received signal based on the third resource. For example, the terminal detects the second synchronization signal block within the same time period as detecting the first synchronization signal block, based on the third resource determined by the acquired target synchronization information. This eliminates the need to determine the third resource before receiving the second synchronization signal block, allowing for earlier reception and reducing the latency of detecting the second synchronization signal block.

[0160] It should be noted that detecting a signal can refer to demodulating or parsing a received signal to determine whether the received signal is the expected signal. For example, detecting the second synchronization signal block can refer to demodulating or parsing a received signal to determine whether the received signal is the second synchronization signal block.

[0161] In this embodiment, the waveform of the first synchronization signal block is modulated using the above modulation method, which can reduce the power consumption and complexity of the terminal's blind detection of the first synchronization signal block.

[0162] Optionally, the terminal detects a first synchronization signal block on the first resource to obtain target synchronization information, including:

[0163] If the terminal detects the first synchronization signal block on the first resource within the first time, the terminal obtains the target synchronization information based on the detected first synchronization signal block.

[0164] The method further includes:

[0165] If the terminal does not detect the first synchronization signal block on the first resource within the first time period, the terminal detects the second synchronization signal block based on the second resource.

[0166] In one implementation, the terminal can detect a first synchronization signal block on a first resource starting from the power-on time. If the terminal detects the first synchronization signal block on the first resource within a first time period, the terminal obtains target synchronization information based on the detected first synchronization signal block. If the terminal does not detect the first synchronization signal block on the first resource within the first time period, the terminal detects a second synchronization signal block based on the second resource.

[0167] It should be noted that if the terminal detects the first synchronization signal block of the first resource for more than a first time and cannot obtain the target synchronization information, the terminal detects the second synchronization signal block of the second resource. The first time can be pre-configured by the network or pre-defined by the protocol.

[0168] Optionally, the terminal detects the first synchronization signal block on the first resource, including:

[0169] The terminal uses either the first mode or the second mode to detect the first synchronization signal block on the first resource;

[0170] The terminal detects the second synchronization signal block based on the third resource, including:

[0171] The terminal uses a second mode to detect the second synchronization signal block based on the third resource;

[0172] The peak power consumption corresponding to the first mode is less than the peak power consumption corresponding to the second mode.

[0173] In one implementation, the terminal may use a first mode to detect a first synchronization signal block on a first resource; and use a second mode to detect a second synchronization signal block based on the third resource.

[0174] It should be noted that the peak power consumption corresponding to the first mode is less than that corresponding to the second mode. This can be understood as the terminal being able to detect the first synchronization signal block with lower power consumption and the second synchronization signal block with higher power consumption. In other words, the complexity of the first synchronization signal block is lower than that of the second synchronization signal block. Specifically, the terminal uses a blind detection method to detect the first synchronization signal block, and the terminal detects the second synchronization signal block based on the second synchronization information, thereby reducing the complexity of detecting the second synchronization signal block.

[0175] It should be noted that, in the embodiments of this application, the first mode described above can be understood or replaced as a first power consumption level, and the second mode described above can be understood or replaced as a second power consumption level.

[0176] To better understand this application, some examples are provided below. In the examples below, the first resource is represented by a first resource set, the second resource by a second resource set, the third resource by a third resource set, the first frequency point by a first frequency point set, and the second frequency point by a second frequency point set.

[0177] Example 1:

[0178] The terminal receives and detects the first synchronization signal block and the second synchronization signal block based on the first frequency point set and the second frequency point set.

[0179] The frequency domain positional relationship between the first frequency point set and the second frequency point set is any one of the following: the candidate frequency points contained in the first frequency point set and the second frequency point set are completely different, and the number of frequency points contained in the first frequency point set is less than the number of frequency points contained in the second frequency point set; the spacing between two adjacent frequency points in the first frequency point set is the same as or different from the spacing between two adjacent frequency points in the second frequency point set.

[0180] Or the candidate frequency points contained in the first frequency point set and the second frequency point set are completely different or partially the same, and the number of frequency points contained in the first frequency point set is less than the number of frequency points contained in the second frequency point set, and the spacing between two adjacent frequency points in the first frequency point set is the same or different from the spacing between two adjacent frequency points in the second frequency point set.

[0181] Alternatively, the first frequency set and the second frequency set contain the same candidate frequency points, and the spacing between two adjacent frequency points in the first frequency set is the same as the spacing between two adjacent frequency points in the second frequency set.

[0182] The frequency points included in the first frequency point set and the frequency points included in the second frequency point set are pre-configured by the network or pre-defined by the protocol.

[0183] In one embodiment, the terminal's receiving bandwidth includes all frequency bands covering the frequency band range corresponding to the first frequency point set and the frequency band range corresponding to the second frequency point set. Within a time length not less than one first synchronization signal block transmission period, the terminal first detects a first synchronization signal block on all frequency points included in the first frequency point set, obtains target synchronization information based on the detected first synchronization signal block, and narrows the time-domain and / or frequency-domain detection range of the second synchronization signal block based on the target synchronization information. The terminal detects the second synchronization signal block in the following ways: within the same time length as detecting the first synchronization signal block, it detects the second synchronization signal block based on the obtained target synchronization information; or in the next time period after the time length during which the target synchronization information is obtained from detecting the first synchronization signal block, it detects the second synchronization signal block based on the target synchronization information.

[0184] In one embodiment, the terminal's first receiving bandwidth is not less than the frequency band range of the first frequency point set, and the terminal's second receiving bandwidth is less than the frequency band range of the second frequency point set. The terminal uses the first receiving bandwidth to receive a first synchronization signal block and the second receiving bandwidth to receive a second synchronization signal block. Within a time length of not less than one transmission period of the first synchronization signal block, the terminal prioritizes detecting the first synchronization signal block on all frequency points included in the first frequency point set. Based on the detected first synchronization signal block, the terminal obtains target synchronization information and narrows the time-domain and / or frequency-domain detection range of the second synchronization signal block based on the target synchronization information. The terminal detects the second synchronization signal block by dividing the second frequency point set into multiple subsets, where the frequency band range corresponding to all frequency points in each subset does not exceed the terminal's second receiving bandwidth. Within multiple transmission periods of the second synchronization signal block, the terminal detects the second synchronization signal block respectively based on the narrowed time-domain and / or frequency-domain detection range of the second synchronization signal block according to the target synchronization information.

[0185] In one embodiment, the terminal's first receiving bandwidth is not less than the frequency band range of the first frequency point set, and the terminal's second receiving bandwidth is not less than the frequency band range of the second frequency point set. Within a time length not less than one first synchronization signal block transmission period, the terminal preferentially detects the first synchronization signal block on all frequency points included in the first frequency point set, obtains target synchronization information based on the detected first synchronization signal block, and narrows the time-domain and / or frequency-domain detection range of the second synchronization signal block based on the target synchronization information. The terminal detects the second synchronization signal block in the following ways: within the same time length as detecting the first synchronization signal block, it detects the second synchronization signal block based on the obtained target synchronization information; or in the next time period after the time length during which the target synchronization information is obtained from detecting the first synchronization signal block, it detects the second synchronization signal block based on the target synchronization information. Otherwise, the second synchronization signal block is not detected.

[0186] In one embodiment, the terminal's first receiving bandwidth is less than the frequency band range corresponding to the first frequency point set. Therefore, the first frequency point set is divided into multiple subsets. The frequency band range corresponding to all frequency points in each subset does not exceed the terminal's first receiving bandwidth. The terminal detects the first synchronization signal block on all frequency points in a corresponding subset within multiple time lengths. Each time length is not less than one first synchronization signal block transmission period. The terminal detects the second synchronization signal block based on the acquired target synchronization information only within the time length during which the first synchronization signal block is detected or in the subsequent time period. Otherwise, the second synchronization signal block is not detected.

[0187] Example 2:

[0188] The terminal determines the frequency domain resources included in the third resource set based on the time domain location information of the first synchronization signal block and the second resource set.

[0189] The terminal detects a first synchronization signal block in the first resource set. Specifically, the terminal detects the first synchronization signal block on all frequency points included in the first frequency point set within a time length of not less than one first synchronization signal block period. One period of the first synchronization signal block includes at least one transmission location set of the first synchronization signal block. Each transmission location set can be associated with at least one candidate frequency point subset set of the second synchronization signal block. Each transmission location set of the first synchronization signal block contains at least one transmission location of the first synchronization signal block. The transmission location of each first synchronization signal block can be used to realize the transmission of the same content in different beams, as shown in Figure 8. All candidate frequency points included in the second frequency point set can be divided into multiple subsets (subset 1, subset 2, ..., subset J). Each subset contains at least one candidate frequency point. The terminal determines at least one candidate frequency point subset of the second synchronization signal block associated with the detected transmission location set identifier of the first synchronization signal block (e.g., transmission location set 1 is associated with subset 1, transmission location set 2 is associated with subset 2, ..., transmission location set J is associated with subset J). The terminal detects the second synchronization signal block only at frequencies included in one or more candidate frequency subsets of the second synchronization signal block associated with one or more successfully detected first synchronization signal block transmission location sets. Optionally, the transmission location set identifier of the first synchronization signal block can be carried by the first synchronization signal block, such as by at least one of a sequence or information block. For the specific method of the terminal receiving and detecting the first and second synchronization signal blocks, please refer to Example 1.

[0190] Example 3:

[0191] The terminal determines the frequency domain resources included in the third resource set based on the frequency domain location information of the first synchronization signal block and the second resource set.

[0192] The terminal detects a first synchronization signal block in a first resource set. Specifically, the terminal detects the first synchronization signal block on all frequency points included in the first frequency point set within a time length of not less than one first synchronization signal block period. The frequency points of the first frequency point set and the frequency points of the second frequency point set are associated, and the association relationship can be predefined by network configuration or protocol. Based on the location of one or more frequency points of the detected first synchronization signal block, the terminal determines the frequency points of one or more associated second frequency point sets. The terminal only detects second synchronization signal blocks on the frequency points of one or more second frequency point sets associated with the frequency points of the successfully detected one or more first synchronization signal blocks. For the specific method of the terminal receiving and detecting the first and second synchronization signal blocks, please refer to Example 1.

[0193] Optionally, the association between the frequency points of the first frequency point set and the frequency points of the second frequency point set includes any of the following:

[0194] As shown in Figure 9, the frequency bands of the first and second frequency point sets do not overlap. The candidate frequency points contained in the first and second frequency point sets are completely different, and the number of frequency points contained in the first frequency point set is less than the number of frequency points contained in the second frequency point set. The spacing between two adjacent frequency points in the first frequency point set may be the same as or different from the spacing between two adjacent frequency points in the second frequency point set. One frequency point in the first frequency point set is associated with at least one frequency point in the second frequency point set.

[0195] As shown in Figure 10, the frequency bands of the first frequency point set and the second frequency point set partially overlap. The candidate frequency points contained in the first frequency point set and the second frequency point set are completely different or partially the same. The number of frequency points contained in the first frequency point set is less than the number of frequency points contained in the second frequency point set. The spacing between two adjacent frequency points in the first frequency point set is the same as or different from the spacing between two adjacent frequency points in the second frequency point set. One frequency point in the first frequency point set is associated with multiple frequency points in the second frequency point set.

[0196] As shown in Figure 11, the frequency bands of the first frequency set and the second frequency set are exactly the same, and the candidate frequency points contained in the first frequency set and the second frequency set are exactly the same. The spacing between two adjacent frequency points in the first frequency set is the same as the spacing between two adjacent frequency points in the second frequency set. A frequency point in the first frequency set is uniquely associated with a frequency point in the second frequency set.

[0197] Example 4:

[0198] The terminal determines the frequency domain resources included in the third resource set based on the first indication information carried by the first synchronization signal block and the second frequency point set.

[0199] The terminal detects a first synchronization signal block in the first resource set. Specifically, the terminal detects the first synchronization signal block on all frequency points included in the first frequency point set within a time length of not less than one first synchronization signal block period, as shown in Figure 12. One period of the first synchronization signal block includes at least one set of transmission positions for the first synchronization signal block. Each set of transmission positions for the first synchronization signal block includes at least one transmission position for the first synchronization signal block. The transmission position of each first synchronization signal block can be used to transmit the same content on different beams. The first synchronization signal block carries first indication information, which includes indication information of one or more frequency point indices in the second frequency point set. Optionally, multiple frequency points in the second frequency point set can be divided into a subset (e.g., subset 1, subset 2, ..., subset J). The first indication information may also include index information of one or more frequency point subsets. The terminal detects the second synchronization signal block only at the frequency points of one or more second synchronization signal blocks indicated by one or more successfully detected first indication information. For the specific method of the terminal receiving and detecting the first and second synchronization signal blocks, please refer to Example 1.

[0200] In one implementation, the methods in Examples 2, 3, and 4 can be used to jointly determine that the third resource set contains frequency domain resources by at least two methods.

[0201] Example 5:

[0202] The terminal determines the time-domain resources included in the third resource set based on the target synchronization information and the second resource set.

[0203] The terminal detects the first synchronization signal block in the first resource set. Specifically, the terminal detects the first synchronization signal block on all frequency points included in the first frequency point set within a time length of not less than one first synchronization signal block period. One period of the first synchronization signal block includes at least one set of transmission positions of the first synchronization signal block. Each set of transmission positions of the first synchronization signal block includes at least one transmission position of the first synchronization signal block. The transmission position of each first synchronization signal block can be used to realize the transmission of the same content in different beams. As shown in Figure 13, the terminal determines a first time domain position or a second time domain position by adding a predefined first time domain offset to the time domain start position or time domain end position of the detected first synchronization signal block. Based on the first time domain position or the second time domain position, it determines a period in the time domain resources of the second resource set. Within the period, the first time domain position or the second time domain position is used as the start position of the time window, and the end position of the period is used as the end position of the time window, or the first time domain position or the second time domain position is added to the second time domain offset as the end position of the time window, to obtain a time window of the time domain resources of the third resource set. The time window repeats in the time domain with a second period, and the values ​​of the first time domain offset and the second time domain offset are greater than or equal to 0.

[0204] In one embodiment, the first synchronization signal block and the second synchronization signal block are transmitted adjacent to each other, and there is no time interval between the end position of the transmission of the first synchronization signal block and the start position of the transmission of the second synchronization signal block, that is, the first time offset is 0.

[0205] In the above example, the terminal can detect the first synchronization signal block using either a low-power mode or a normal power mode, and detect the second synchronization signal block using a normal power mode. The peak power consumption of the low-power mode is lower than that of the normal power mode, and the low-power mode can be implemented using a low-power receiver.

[0206] In one implementation, the candidate frequency points of the first frequency point set and the second frequency point set are associated with at least one of the following:

[0207] Operating frequency bands, including type (such as Time Division Duplex (TDD), Frequency Division Duplex (FDD), licensed and unlicensed, etc.) and frequency band range;

[0208] The subcarrier spacing of the first synchronization signal block, for example, the subcarrier spacing used by the OFDM generator used to generate the first synchronization signal block;

[0209] Global synchronization channel number (GSCN);

[0210] Absolute Radio Frequency Channel Number (ARFCN);

[0211] Frequency bands supported by the terminal.

[0212] Examples 1 to 5 above can be combined with each other, and all of Examples 1 to 5 above can be combined with the embodiments of FIG7 as supplementary explanations to the embodiments of FIG7.

[0213] The synchronization signal block detection method provided in this application can be executed by a synchronization signal block detection device. This application uses the synchronization signal block detection device executing the synchronization signal block detection method as an example to illustrate the synchronization signal block detection device provided in this application.

[0214] Please refer to Figure 14, which is a structural diagram of a synchronization signal block detection device provided in an embodiment of this application. The terminal includes the synchronization signal block detection device. As shown in Figure 14, the synchronization signal block detection device 200 includes:

[0215] The first detection module 201 is used to detect the first synchronization signal block on the first resource and obtain target synchronization information;

[0216] The determining module 202 is used to determine a third resource in the second resource based on the target synchronization information, wherein the second resource is a resource associated with the second synchronization signal block;

[0217] The second detection module 203 is used to detect the second synchronization signal block based on the third resource;

[0218] The first synchronization signal block adopts any of the following waveforms or modulation methods: Amplitude Shift Keying (ASK); Frequency Shift Keying (FSK); On / Off Keying (OOK) superimposed Orthogonal Frequency Division Multiplexing (OFDM); OFDM.

[0219] Optionally, the frequency domain resources in the first resource include a first frequency point, which includes candidate frequency points for the transmission of the first synchronization signal block; or, the time domain resources in the first resource include time domain resources determined by repeating in the time domain by a first time window with a first cycle length.

[0220] or

[0221] The frequency domain resources in the second resource include a second frequency point, which includes a candidate frequency point for the transmission of the second synchronization signal block; or, the time domain resources in the second resource include time domain resources determined by the second time window repeating in the time domain with a second period length.

[0222] Wherein, the length of the first period is less than or equal to the length of the second period.

[0223] Optionally, the first frequency point and the second frequency point satisfy a first condition, which includes any one of the following:

[0225] The first frequency point and the second frequency point have some frequency points that are the same, and the number of frequency points of the first frequency point is less than the number of frequency points of the second frequency point;

[0226] The first frequency point is the same as the second frequency point.

[0227] Optionally, the first period length is a network configuration or a first duration predefined by the protocol; or, the first period length is a second duration determined by the terminal according to the network instruction.
