It should be noted that in the embodiment of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0070] To facilitate a better understanding of the embodiments of the present application, the technologies related to the present application are explained.

[0071] (1) Synchronization signal and Physical Broadcast Channel (PBCH).

[0072] FIG2 is an example of the structure of the SSB provided in an embodiment of the present application.

[0073] As shown in Figure 2, the terminal first detects the Primary Synchronization Signal (PSS) to obtain a portion of the physical cell ID, namely N(2)_ID; obtains Orthogonal Frequency Division Multiplexing (OFDM) symbol timing and frequency synchronization; then detects the Secondary Synchronization Signal (SSS) to obtain the other portion of the physical cell ID, namely N(1)_ID, and obtains the complete physical cell ID, namely the Physical Cell Identity (PCI). The terminal then detects the PBCH and the demodulation reference signal (DMRS) for demodulating the PBCH to obtain the system frame number (System Frame Number) and SSB index, and further obtains the radio frame (subframe) timing.

[0074] In other words, in order for a terminal to search for a suitable cell and synchronize with it, the network typically broadcasts synchronization signals and provides certain master information about the cell. Synchronization signals primarily include the PSS and SSS. The PBCH carries the most important system information, also known as the Master Information Block (MIB).

[0075] (2) SSB to RO mapping rules in 5G NR.

[0076] The configuration parameters for the Physical Random Access Channel (PRACH) resources and SSB-RO are configured in the System Information Block (SIB1). In NR, a cell can configure multiple frequency division multiplexing (FDM) PRACH transmission opportunities (PRACH Occasions, ROs) at a single PRACH transmission time location. The number of ROs that can be FDMed at a given time can be: {1, 2, 4, 8}, which is configured and determined by the higher-layer parameter msg1-FDM.

[0077] The random access preamble can only be transmitted on the time domain resources configured by the parameter PRACHConfigurationIndex and the frequency domain resources configured by the parameter msg1-FDM. RA∈{0,1,…,M-1}, where M is equal to the high-level parameter msg1-FDM. At the time of initial access, the PRACH frequency domain resource n RA The PRACH frequency domain resource n is numbered in ascending order starting from the lowest frequency RO resource in the initial active uplink bandwidth part. Otherwise, the PRACH frequency domain resource n is RA The RO resources are numbered in ascending order, starting from the lowest frequency RO resource within the active uplink bandwidth part. For example, as shown in Figure 3, the number of ROs in frequency division multiplexing (FDM) at a time can be 8 (msg1-FDM=8). The RO resources are numbered from RO#0 to RO#7 in ascending order of frequency.

[0078] In NR, there is an association between RO and the SSB actually sent. RO is associated to SSB in the order of frequency domain (from low frequency to high frequency) and then time domain. One SSB may be associated with multiple consecutive ROs, or multiple SSBs may be associated with one RO (in this case, different SSBs correspond to different preambles), which is configured by the network through the parameter ssb-perRACH-OccasionAndCB-PreamblesPerSSB. For example, oneEighth means that one SSB is associated with 8 consecutive ROs, and eight means that 8 SSBs are associated with one RO. {n4, n8, n12, ...} represents the number of preambles associated with each SSB on an RO. For example, the value n4 means that the number of preambles associated with each SSB on an RO is 4, and n8 means that the number of preambles associated with each SSB on an RO is 8.

[0079] After all SSBs have completed one round of association with the RO, an SSB-RO mapping cycle is formed. An SSB-RO association period may include one or more SSB-RO mapping cycles. An SSB-RO association pattern period may include one or more SSB-RO association periods. The SSB-RO mapping is repeated based on the association pattern period, and the maximum association pattern period is 160ms.

[0080] Typically, a base station can use different beams to transmit different SSBs. The number of SSBs is configured using the ssb-PositionsInBurst parameter. For FR2, the maximum number of SSBs is 64. Based on the strength of the received downlink beam / SSB, the UE selects the RO / RO and preamble combination associated with the SSB with a good signal and sends Msg1. The network then determines the SSB selected by the UE based on the RO / RO and preamble combination of the received preamble. Msg2 is then sent on the downlink beam corresponding to the SSB to ensure downlink signal reception quality.

[0081] Taking Figure 3 as an example, the number of FDM ROs at a given moment is eight, and the number of SSBs actually transmitted is four, namely SSB#0, SSB#1, SSB#2, and SSB#3. Each SSB is associated with two ROs. If the UE determines to send PRACH / Mg1 on the RO corresponding to SSB#0, the UE selects one RO between RO#0 and RO#1 to send the PRACH.

[0082] Taking Figure 4 as an example, at a given moment in time, the number of FDM ROs is 2, and the number of SSBs actually transmitted is 8, namely SSB#0, SSB#1, ..., SSB#7, with one RO associated with every two SSBs. When multiple SSBs share a RO, the preamble sets associated with these multiple SSBs are different. That is, the same preamble cannot belong to the preamble sets associated with different SSBs at the same time. Taking RO#0 in Figure 4 as an example, RO#0 has a total of 60 preambles, of which preambles with indexes 0 to 29 are associated with SSB#0, and preambles with indexes 30 to 59 are associated with SSB#1.

[0083] It is worth noting that in Figure 4, each square represents a RO, not an SSB, and the labeled SSB refers to which SSB(s) this RO is associated with.

[0084] Before sending PRACH, the UE first selects an SSB with a Reference Signal Receiving Power (RSRP) higher than a threshold based on the RSRP of the received beam. If the RSRP of multiple SSBs is higher than the threshold, the terminal can select any SSB with RSRP higher than the threshold. If there is no SSB with RSRP higher than the threshold, the UE selects an SSB based on the implementation.

[0085] Based on the NW (Network) configuration, the UE obtains the correspondence between the SSB and the RO. After selecting the SSB, the RO corresponding to the selected SSB is used as the RO for sending PRACH / Preamble / Msg1. If the selected SSB is associated with multiple ROs, the terminal can select one of the ROs for sending PRACH / Preamble / Msg1.

[0086] Taking Figure 3 as an example, assuming that the UE selects SSB#1, the UE can select one from RO#2 and RO#3 to send PRACH / Msg1; taking Figure 4 as an example, if the UE selects SSB#1, the UE can select the available RO closest to the current time among the ROs (RO#0 or 4) associated with SSB#1 to send PRACH / Msg1. In the selected RO, the UE selects a preamble from the preamble set associated with the selected SSB to send PRACH. As shown in Figure 4, if one RO is associated with two SSBs, then the preambles in the available preamble set associated with the SSB in one RO will be divided into two subsets, each corresponding to one SSB. The UE will select a preamble from the preamble subset corresponding to the selected SSB for sending PRACH / Msg1.

[0087] (3) Determination of the RO set when PRACH is repeatedly transmitted.

[0088] Rel-18 introduced PRACH repetition to enhance uplink coverage. For PRACH repetition, the UE needs to repeatedly transmit the preamble on multiple ROs at different time-domain locations associated with the same SSB. The repetition count can be {2, 4, 8}. After determining the PRACH repetition count, the UE needs to determine the RO set. The number of valid ROs in the RO set is equal to the PRACH repetition count. Assuming the PRACH repetition count is N, the RO group determination rule is as follows: first, the starting RO of the RO group is determined, then the remaining N-1 ROs in the RO group are determined. The remaining N-1 ROs in each RO group are ROs associated with the same SSB, the same frequency position, and the same associated preamble set as the starting RO. For example, as shown in Figure 5, assuming the PRACH repetition count is 2, for SSB#0, the starting RO of the RO group is first determined, then the remaining RO in the RO group is determined. The remaining RO in each RO group is RO associated with the same SSB#0, the same frequency position, and the same associated preamble set as the starting RO.

[0089] In 5G networks, SSB configuration is configured by system messages, and the SSB resource configuration can only be changed through RRC reconfiguration information.

[0090] In addition, for different SSB indexes, the transmission period and transmission power are consistent, and if an SSB index is not sent in a certain period, it cannot be sent in other periods. Unless the system message is updated, whether a certain SSB index is sent can be changed.

[0091] In this embodiment, the system load may not be the same for different SSB indices or SSB index groups, meaning that the required SSB resources need to be flexibly configured. Furthermore, for different SSB indices or SSB index groups, the expected coverage may also be different, and the corresponding required transmission power may also be different.

[0092] In view of this, an embodiment of the present application provides an SSB configuration method that can improve the flexibility of SSB configuration.

[0093] It is worth noting that the SSB involved in this application can also be called any module that includes at least one of a synchronization signal, a broadcast signal, a broadcast channel (PBCH), and other system message downlink broadcast channels.

[0094] In addition, the reference signals involved in this application include but are not limited to SSB, Channel State Information Reference Signal (CSI-RS), Tracking Reference Signal (TRS), Message A (MsgA), MsgA Physical Uplink Shared Channel (PUSCH), Physical Random Access Channel (PRACH), Cell Group (CG) PUSCH. The reference signal may include a reference signal of one cell or a reference signal of multiple cells. The cells may be of the same frequency carrier or different frequency carriers, and may be within a frequency band or in different frequency bands.

[0095] The SSB configuration method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0096] FIG6 is a schematic flowchart of an SSB configuration method 200 according to an embodiment of the present application.

[0097] As shown in FIG6 , the SSB configuration method 200 may include at least part of the following:

[0098] S210: The terminal receives at least one SSB configuration from the network-side device.

[0099] The at least one SSB configuration includes at least one of the following:

[0100] A first SSB configuration for configuring SSB resources, a second SSB configuration for configuring an SSB for performing radio resource management (RRM) measurements, and a third SSB configuration for configuring SSB transmit power;

[0101] The configuration mode of the at least one SSB configuration includes at least one of the following:

[0102] A first configuration mode based on an SSB index, a second configuration mode based on an SSB index group, or a third configuration mode based on multiple first time units in a first time window.

[0103] In this embodiment, SSB resources, SSBs used for RRM measurement, or SSB transmit power can be flexibly configured based on the granularity of the SSB index, SSB index group, or the first time unit within the first time window, thereby avoiding the network configuring the same period and transmit power for different SSB indexes. This improves the flexibility of SSB configuration.

[0104] Specifically, considering that different SSB indexes or SSB index groups may have different system loads, in this embodiment, the SSB resources or the SSB used for RRM measurement can be flexibly configured based on the SSB index, SSB index group, or the first time unit in the first time window. In addition, considering that the reception performance of SSBs may be different for different SSB positions, time domain diversity is required to improve SSB performance. In addition, improving the location flexibility of SSBs is beneficial for the network to schedule other signals, especially when the scheduling signal is a periodic signal and the uplink subband is configured for the downlink time slot in the enhanced duplex mode.

[0105] Similarly, for different SSB indexes or SSB index groups, the expected coverage range may also be different, and the corresponding required transmission power may also be different. In this embodiment, the SSB transmission power can be flexibly configured based on the SSB index, SSB index group or the first time unit in the first time window, thereby achieving a more flexible SSB transmission power configuration.

[0106] In some embodiments, when the configuration mode of the first SSB or the configuration mode of the second SSB configuration is the first configuration mode, the first configuration mode satisfies at least one of the following:

[0107] The same SSB index corresponds to one or more SSBs;

[0108] The SSBs corresponding to the same SSB index have the same type or attribute;

[0109] Each SSB index is configured with an independent period;

[0110] The periods of different SSB indexes are multiples of each other or the period of each SSB index is a multiple of the minimum time unit;

[0111] The resource position of the SSB corresponding to the same SSB index is fixed within the cycle;

[0112] The resource position of the SSB corresponding to the same SSB index within the period is determined according to the first information, which is configured through the network or agreed upon by the protocol;

[0113] Different SSB indexes have the same period, and some SSB indexes are deactivated within a portion of the period within the second time window;

[0114] Different SSB index configurations have the same first period, and some SSB index configurations have a second period or correspond to multiple resource locations within the first period.

[0115] Exemplarily, the same SSB index corresponds to one or more SSBs within a cycle.

[0116] Exemplarily, the types or attributes of the SSBs corresponding to the same SSB index are the same, including but not limited to: the coverage requirements of the SSBs corresponding to the same SSB index are the same, and the waveforms of the SSBs corresponding to the same SSB index are the same.

[0117] Exemplarily, the periods of different SSB indexes may be the same or different.

[0118] Exemplarily, the minimum time unit may be a time unit configured by the network or a time unit agreed upon by a protocol. In other words, the length of the minimum time unit may be configured by the network or agreed upon by a protocol.

[0119] Exemplarily, the minimum time unit is smaller than the period of any SSB index.

[0120] Exemplarily, the resource position of the SSB corresponding to the same SSB index in any cycle is fixed.

[0121] Exemplarily, the resource position of the SSB corresponding to the same SSB index in any period thereof is determined according to the first information.

[0122] Exemplarily, the periods of different SSB indexes are the same, and some SSB indexes are deactivated within part of the period within the second time window. This can also be understood or replaced as: the periods of different SSB indexes are the same, and some SSB indexes are not sent or received within part of the period within the second time window.

[0123] Exemplarily, the second period is within the first period, and the first period is a multiple of the second period.

[0124] In some embodiments, the first information is used to indicate the position of the SSB corresponding to the same SSB index in a time period within a cycle.

[0125] Exemplarily, the first information is used to indicate the position of the SSB corresponding to the same SSB index in a time period within any one of its cycles.

[0126] For example, assuming that the SSB0 period is 20ms, the first information is used to indicate which 5ms of the SSB corresponding to SSB0 is in the 20ms period. For example, the first information is 2 bits, and its values ​​0, 1, 2, and 3 respectively indicate the first, second, third, and fourth 5ms.

[0127] In some embodiments, when the configuration mode of the first SSB or the configuration mode of the second SSB configuration is the second configuration mode, the second configuration mode satisfies at least one of the following:

[0128] The same SSB index in the same SSB index group corresponds to one or more SSBs;

[0129] The SSBs corresponding to the same SSB index group have the same type or attribute;

[0130] The terminal is configured with one or more SSB index groups;

[0131] The number of SSB indexes in different SSB index groups is the same;

[0132] Each SSB index group is configured with an independent number of SSB indexes;

[0133] Different SSB index groups correspond to the same number of SSBs;

[0134] Each SSB index group corresponds to an independently configured number of SSBs;

[0153] Exemplarily, the fourth period is within the third period, and the third period is a multiple of the fourth period.

[0213] Exemplarily, the first reference signal may be any reference signal in the SSB, for example, including but not limited to: a synchronization signal, a broadcast signal, a broadcast channel (PBCH), other system message downlink broadcast channels, etc.

[0236] Of course, the network configuration signaling may also be any semi-static information or dynamic signaling, and this application does not impose any specific limitation on this.

[0237] In some embodiments, at least one of the following items corresponding to the network configuration signaling is the same as or different from at least one of the following items corresponding to the configured SSB: carrier, cell, frequency band, bandwidth part (Bandwidth Part, BWP).

[0238] In this embodiment, at least one of the following items corresponding to the network configuration signaling is the same as or different from at least one of the following items corresponding to the configured SSB: carrier, cell, frequency band, BWP; equivalently, the network configuration signaling and the configured SSB can be on the same or different carriers, cells, frequency bands, and BWPs. Specifically, when the network configuration signaling and the configured SSB are on the same carrier, cell, frequency band or BWP, the signaling overhead of the at least one SSB configuration can be reduced. When the network configuration signaling and the configured SSB are on different carriers, cells, frequency bands or BWPs, the flexibility of the at least one SSB configuration can be improved.

[0239] The SSB configuration method provided in this application is described below with reference to specific embodiments.

[0240] Example 1:

[0241] For different SSB indexes or SSB index groups, the system load may not be the same, and the resources of the SSB need to be flexibly configured.

[0242] In some embodiments, the configuration of the time-frequency resources of the SSB is determined by one or more of the following methods:

[0243] Supports SSB resource determination for each SSB index. That is, different SSB indexes introduce independent SSB time and frequency resource determination.

[0244] Optionally, there may be one or more SSBs corresponding to one SSB index.

[0245] Optionally, these SSBs correspond to the same type / attribute (such as coverage requirements, waveform, etc.).

[0246] Supports SSB resource configuration for each SSB index group. That is, different SSB index groups introduce independent SSB time and frequency resource determination.

[0247] Optionally, SSBs belonging to the same group correspond to the same type / attribute (such as coverage requirements, waveform, etc.).

[0248] Supports SSB resource configuration based on the first time unit in the first time window, that is, different first time units in the first time window are configured with independent or different SSB time-frequency resources.

[0249] As a first sub-embodiment, the SSB resource determination per SSB index further includes one or more of the following methods:

[0250] 1. Each SSB index has an independent SSB period configuration.

[0251] 2. The SSB periods of different SSB indexes are multiples or multiples of a minimum time unit (such as 5ms).

[0252] 3. The position of the same SSB index in the corresponding SSB period is fixed.

[0253] For example, four SSBs are configured: SSB0, SSB1, SSB2, and SSB3. The period of SSB0 is 20ms, the period of SSB1 is 40ms, the period of SSB2 is 80ms, and the period of SSB3 is 160ms. To reduce the complexity of SSB search, the position of SSB0 is fixed within each 20ms period, the position of SSB1 is fixed within each 40ms period, the position of SSB2 is fixed within each 80ms period, and the position of SSB3 is fixed within each 160ms period.

[0254] 4. The position of the same SSB index within the corresponding SSB period is determined according to a certain pattern, which is specified by the network configuration or protocol.

[0255] Considering that different SSB locations may have different SSB reception performance, time domain diversity is needed to improve SSB performance. Furthermore, increasing SSB location flexibility facilitates network scheduling of other signals, particularly when scheduling periodic signals and configuring uplink subbands for downlink timeslots in enhanced duplex mode.

[0256] For example, four SSBs are configured, namely SSB0, SSB1, SSB2, and SSB3. The period of SSB0 is 20ms, the period of SSB1 is 40ms, the period of SSB2 is 80ms, and the period of SSB3 is 160ms.

[0257] The 5ms of each 20ms period during which the SSB0 is transmitted is determined by two bits. A value of 0, 1, 2, or 3 indicates that the SSB0 is transmitted in the first, second, third, or fourth 5ms of each 20ms period, respectively.

[0258] The 10ms of each 40ms period in which the SSB1 is transmitted is determined by two bits. The values ​​of the two bits are 0, 1, 2, and 3, indicating that the SSB is transmitted in the first, second, third, and fourth 10ms, respectively.

[0259] The 20ms within each 80ms that the SSB2 is sent is determined by two bits. The values ​​of the two bits are 0, 1, 2, and 3, indicating that the SSB is sent in the first, second, third, and fourth 20ms, respectively.

[0260] The 40ms of each 160ms period in which the SSB3 is sent is determined by two bits. A value of 0, 1, 2, or 3 indicates that the SSB is sent in the first, second, third, or fourth 40ms, respectively.

[0261] 5. All SSB indexes are configured with the same SSB period, and some SSB indexes are not sent in certain SSB periods.

[0262] To reduce the configuration complexity of the SSB period, you can additionally configure whether to send SSBs with certain SSB indexes on certain periods. The certain periods here can be certain periods of multiple SSB periods within a time window.

[0263] For example, if the SSB period is configured to 20ms, this time window includes 4 SSB periods (i.e., 80ms). If the number of SSBs actually sent is configured to be 4, with SSB indexes 0, 1, 2, and 3, the following example is used to configure whether to send SSBs with certain SSB indexes in certain periods:

[0264] SSB0 is sent every 20ms within every 80ms;

[0265] SSB1 is sent in the first, second, and third 20ms of every 80ms, but not in the fourth 20ms.

[0266] SSB2 is sent in the first and second 20ms of every 80ms, but not in the third and fourth 20ms.

[0267] SSB3 is sent in the first 20ms of every 80ms, and is not sent in the second, third, and fourth 20ms.

[0268] For example, the above configuration can introduce a 4-bit bitmap to determine which of the four 20ms periods the corresponding SSB index will be sent. The bitmap values ​​for SSB0, SSB1, SSB2, and SSB3 are {1111, 1110, 1100, 1000}, where a bit value of 0 indicates not sending and a bit value of 1 indicates sending.

[0269] 6. All SSB indices are configured with the same SSB period, but some SSB indices can be configured with additional periods or additional positions. Additional periods can be understood as configuring multiple sub-periods within an SSB period. Additional positions can be understood as additionally adjusting the time-frequency domain positions of certain SSB indices within an SSB period.

[0270] As a second sub-embodiment, determining the SSB resources for each SSB index group further includes one or more of the following methods:

[0271] 1. The network configures one or more SSB groups.

[0272] 2. Each SSB group has the same number of SSBs.

[0273] 3. Each SSB group has an independently configured number of SSBs.

[0274] 4. The SSB index of each SSB group is continuous or determined according to a certain pattern.

[0275] 5. Each SSB index group has an independent SSB period configuration.

[0276] 6. The SSB periods of different SSB index groups are multiples or multiples of a minimum time unit (such as 5ms).

[0277] 7. The position of the same SSB index group within the corresponding SSB period is fixed.

[0278] For example, if four SSB groups are configured, namely {SSB0, SSB1, SSB2, SSB3}, {SSB4, SSB5, SSB6, SSB7}, {SSB8, SSB9, SSB10, SSB11}, and {SSB12, SSB13, SSB14, SSB15}, the period of {SSB0, SSB1, SSB2, SSB3} is 20ms, the period of {SSB4, SSB5, SSB6, SSB7} is 40ms, the period of {SSB8, SSB9, SSB10, SSB11} is 80ms, and the period of {SSB12, SSB13, SSB14, SSB15} is 160ms. To reduce the complexity of SSB search, the positions of {SSB0, SSB1, SSB2, SSB3} are fixed within each 20ms period, the positions of {SSB4, SSB5, SSB6, SSB7} are fixed within each 40ms period, the positions of {SSB8, SSB9, SSB10, SSB11} are fixed within each 80ms, and the positions of {SSB12, SSB13, SSB14, SSB15} are fixed within each 160ms.

[0279] 8. The position of the same SSB index group within the period of the corresponding SSB group is determined according to a certain pattern, which is specified by the network configuration or protocol.

[0280] Considering that the SSB positions within different SSB groups may have different effects on SSB reception performance, time domain diversity is needed to improve SSB performance. Furthermore, increasing the flexibility of SSB positions within an SSB group can facilitate network scheduling of other signals, particularly when scheduling signals are periodic and when uplink subbands are configured in downlink time slots in enhanced duplex mode.

[0281] For example, four SSB groups are configured, namely {SSB0, SSB1, SSB2, SSB3}, {SSB4, SSB5, SSB6, SSB7}, {SSB8, SSB9, SSB10, SSB11}, {SSB12, SSB13, SSB14, SSB15}. The period of {SSB0, SSB1, SSB2, SSB3} is 20ms, the period of {SSB4, SSB5, SSB6, SSB7} is 40ms, the period of {SSB8, SSB9, SSB10, SSB11} is 80ms, and the period of {SSB12, SSB13, SSB14, SSB15} is 160ms.

[0282] Two bits determine which 5ms of each 20ms period {SSB0, SSB1, SSB2, SSB3} are sent. A value of 0, 1, 2, or 3 indicates that the SSB group is sent in the first, second, third, or fourth 5ms of each 20ms period, respectively.

[0283] The 10ms of each 40ms period in {SSB4, SSB5, SSB6, SSB7} is determined by two bits. The values ​​of these two bits are 0, 1, 2, and 3, indicating that the SSB group is sent in the first, second, third, and fourth 10ms, respectively.

[0284] The 20ms interval within each 80ms interval for {SSB8, SSB9, SSB10, SSB11} is determined by two bits. A value of 0, 1, 2, or 3 indicates that the SSB group is sent in the first, second, third, or fourth 20ms interval, respectively.

[0285] The 40 ms of each 160 ms interval for {SSB12, SSB13, SSB14, SSB15} is determined by two bits. A value of 0, 1, 2, or 3 indicates that the SSB group is sent in the first, second, third, or fourth 40 ms, respectively.

[0286] 9. All SSB index groups are configured with the same SSB period, and some SSB index groups are not sent in certain SSB periods.

[0287] To reduce the configuration complexity of the SSB period, the same SSB period can be configured for all SSB groups, and additional configuration can be made as to whether SSBs of certain SSB index groups are sent on certain periods. The certain periods here can be certain periods of multiple SSB periods within a time window.

[0288] For example, if the SSB period is configured to 20ms, this time window includes 4 SSB periods (i.e., 80ms); if the number of SSB groups actually sent is configured to be 4, each group has four SSBs, namely SSB index groups {SSB0, SSB1, SSB2, SSB3}, SSB4, SSB5, SSB6, SSB7}, {SSB8, SSB9, SSB10, SSB11}, {SSB12, SSB13, SSB14, SSB15}, an example of additionally configuring whether to send SSBs of certain SSB index groups in certain periods is as follows:

[0289] {SSB0, SSB1, SSB2, SSB3}, sent every 20ms within every 80ms;

[0290] {SSB4, SSB5, SSB6, SSB7} are sent in the first, second, and third 20ms of every 80ms, but not in the fourth 20ms;

[0291] {SSB8, SSB9, SSB10, SSB11} are sent in the first and second 20ms of every 80ms, but not in the third and fourth 20ms;

[0292] {SSB12, SSB13, SSB14, SSB15}, sent in the first 20ms of every 80ms, and not sent in the second, third, and fourth 20ms;

[0293] For example, the above configuration can introduce a 4-bit bitmap to determine in which 20ms of the four 20ms the corresponding SSB index group will be sent. The bitmap values ​​corresponding to the SSB index groups {SSB0, SSB1, SSB2, SSB3}, {SSB4, SSB5, SSB6, SSB7}, {SSB8, SSB9, SSB10, SSB11}, {SSB12, SSB13, SSB14, SSB15} are {1111, 1110, 1100, 1000}, where a bit value of 0 indicates that the corresponding SSB group is not sent in the corresponding 20ms, and a bit value of 1 indicates that the corresponding SSB group is sent in the corresponding 20ms.

[0294] 10. All SSB index groups are configured with the same SSB period, but some SSB index groups can be configured with (additional) periods or additional positions. Additional periods can be understood as configuring multiple sub-periods within an SSB period. Additional positions can be understood as additionally adjusting the time-frequency domain positions of certain SSB index groups within an SSB period.

[0295] As a third sub-embodiment, the SSB resource configuration based on the first time unit in the first time window also includes one or more of the following methods:

[0296] 1. The network configuration or protocol specifies the start time of the first time unit.

[0297] For example, the start time is SFN 0 or HFN 0.

[0298] For example, the network configuration or protocol stipulates that the start time is a time offset value (time offset) of SFN0.

[0299] 2. The network configures SSB resource modes on different first time units within the first time window.

[0300] The SSB resource mode can be configured according to different SSB indexes or according to different SSB index groups.

[0301] The first time window may be a periodic window. For example, N first time units may be a period, where N is specified by network configuration or protocol.

[0302] For example, the protocol specifies that the first time unit is 640ms, N=2, that is, the first time window is 1280ms. The network configures one SSB resource configuration mode every even 640ms and another SSB resource configuration mode every odd 640ms.

[0303] 3. The first time unit is associated with one or more periods of the following indications:

[0304] The mapping period of SSB to other reference signals;

[0305] The correlation period of SSB to other reference signals;

[0306] The correlation pattern period of SSB to other reference signals;
