Description

Technical Field

And if an SSB index does not transmit in a certain period, it cannot transmit in other periods either, unless the system message is updated, then it is possible to change whether an SSB index transmits.

[0059] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope protected by the present application.

[0060] The terms "first", "second", etc. in this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances, so that the embodiments of this application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first" and "second" are generally of the same type, and do not limit the number of objects. For example, the first object can be one or more. In addition, "or" in this application means at least one of the connected objects.

The following description describes the New Radio (NR) system for example purposes, and uses NR terms in most of the following descriptions, but these technologies can also be applied to systems other than the NR system, such as the 6th Generation (6G) communication system.

[0063] Figure 1 It is a schematic diagram of a communication system architecture provided by an embodiment of the present application.

[0064] As Figure 1 shown, the communication system architecture includes a terminal 11 and a network-side device 12.

[0065] Among them, the terminal 11 can be a mobile phone, a tablet personal computer, a laptop computer, a notebook computer, a personal digital assistant (PDA), a handheld computer, a netbook, an ultra-mobile personal computer (UMPC), a mobile internet device (MID), an augmented reality (AR), a virtual reality (VR) device, a robot, a wearable device, an aircraft, a vehicle user equipment (VUE), a shipborne device, a pedestrian user equipment (PUE), a smart home (home appliances with wireless communication functions, such as refrigerators, TVs, washing machines or furniture, etc.), a game console, a personal computer (PC), a teller machine or a self-service machine, etc. Wearable devices include: smart watches, smart bracelets, smart earphones, smart glasses, smart jewelry (smart bracelets, smart bracelets, smart rings, smart necklaces, smart anklets, smart ankle chains, etc.), smart wristbands, smart clothing, etc. Among them, the vehicle user equipment can also be called a vehicle terminal, a vehicle controller, a vehicle module, a vehicle component, a vehicle chip or a vehicle unit, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present application.

[0066] The network-side device 12 may include an access network device or a core network device.

[0067] Among them, the access network device can also be referred to as a Radio Access Network (RAN) device, a radio access network function, or a radio access network unit. The access network device may include a base station, a Wireless Local Area Network (WLAN) Access Point (AP), or a Wireless Fidelity (WiFi) node, etc. Among them, the base station can be referred to as Node B (NB), Evolved Node B (eNB), the next generation Node B (gNB), New Radio Node B (NR Node B), access point, Relay Base Station (RBS), Serving Base Station (SBS), Base Transceiver Station (BTS), radio base station, radio transceiver, Basic Service Set (BSS), Extended Service Set (ESS), home Node B (HNB), home evolved Node B, Transmission Reception Point (TRP), or some other suitable term in the art. As long as the same technical effect is achieved, the base station is not limited to specific technical terms. It should be noted that in the embodiments of this application, only the base station in the NR system is taken as an example for introduction, and the specific type of the base station is not limited.

[0068] For better understanding of the embodiments of this application, the related technologies of this application are described.

[0069] (1) Synchronization Signal and Physical Broadcast Channel (PBCH).

[0070] Figure 2 It is an example of the structure of the SSB provided by the embodiments of this application.

[0071] Such as Figure 2As shown, the terminal first detects the Primary Synchronization Signal (PSS) to obtain a part of the Physical Cell Identity (ID), i.e., N(2)_ID; obtains Orthogonal Frequency Division Multiplexing (OFDM) symbol timing and frequency synchronization; then detects the Secondary Synchronization Signal (SSS) to obtain another part of the Physical Cell ID, i.e., N(1)_ID, and gets the complete Physical Cell ID, i.e., the Physical Cell Identity (PCI). Then the terminal detects the Physical Broadcast Channel (PBCH) and the Demodulation Reference Signal (DMRS) for demodulating the PBCH to obtain the System Frame Number and the SSB index, and further obtains the subframe timing.

[0072] In other words, to enable the terminal to search for reasonable cells and synchronize with the selected cell, it is usually necessary for the network to broadcast synchronization signals and provide certain primary information about the cell. The synchronization signals mainly include PSS and SSS. The PBCH carries the most important system information and can also be called the Master Information Block (MIB).

[0073] (2) Mapping rules from SSB to RO in 5G NR.

[0074] The Physical Random Access Channel (PRACH) resources and the configuration parameters of SSB-RO are configured in System Information Block SIB1. In NR, a cell can configure multiple Frequency Division Multiplexing (FDM) Physical Random Access Channel transmission opportunities (PRACH transmission occasion, PRACH Occasion, RO) in the time domain position for transmitting PRACH. At a certain moment, the number of FDM ROs that can be performed can be: {1, 2, 4, 8}, which is configured and determined by the high-layer parameter msg1-FDM.

[0075] 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. PRACH frequency domain resource n RA∈ {0, 1, …, M - 1}, where M is equal to the high-layer parameter msg1-FDM. At initial access, the PRACH frequency-domain resource n RA is numbered in ascending order starting from the lowest-frequency RO resource within the initial active uplink bandwidth part, otherwise, the PRACH frequency-domain resource n RA is numbered in ascending order starting from the lowest-frequency RO resource within the active uplink bandwidth part. For example, as Figure 3 shown, the number of ROs for frequency division multiplexing (FDM) at a certain moment can be 8 (msg1-FDM = 8), and the RO resources are numbered as RO#0 to RO#7 in ascending order of frequency.

[0076] In NR, there is an association relationship between ROs and the actually transmitted SSBs. ROs are associated with SSBs in the order of frequency domain (from low frequency to high frequency) first and then time domain. One SSB may be associated with multiple consecutive ROs, or multiple SSBs may be associated with 1 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 represents that one SSB is associated with 8 consecutive ROs, and eight represents that 8 SSBs are associated with 1 RO. {n4, n8, n12, …} represents the number of preambles associated with each SSB on one RO. For example, the value n4 represents that the number of preambles associated with each SSB on one RO is 4, and n8 represents that the number of preambles associated with each SSB on one RO is 8.

[0077] After all SSBs are associated with ROs in one round, it constitutes an SSB-RO mapping cycle. The association period of one SSB to ROs may contain one or more SSB-RO mapping cycles. The association pattern period of one SSB to ROs may contain one or more SSB-RO association periods, and the mapping of SSB to RO is repeated in cycles with the association pattern period, and the maximum association pattern period is 160 ms.

[0078] Generally, the base station can use different beams to transmit different SSBs. The number of SSBs is configured by the ssb-PositionsInBurst parameter. For FR2, the maximum number of SSBs is 64. The UE selects the RO / "RO and preamble combination" associated with the SSB with good signal according to the strength of the received downlink beam / SSB and sends Msg1. In this way, the network can determine the SSB selected by the UE based on the received RO / "RO and preamble combination" of the Preamble, and send Msg2 on the downlink beam corresponding to the SSB to ensure the reception quality of the downlink signal.

[0079] Take Figure 3 as an example. The number of ROs of FDM at a certain moment is 8, and the actual number of transmitted SSBs is 4, namely SSB#0, SSB#1, SSB#2, SSB#3, and each SSB is associated with 2 ROs. If the UE determines to send PRACH / Msg1 on the RO corresponding to SSB#0, then the UE selects one RO from RO#0 and RO#1 to send PRACH.

[0080] Take Figure 4 as an example. The number of ROs of FDM at a certain moment is 2, and the actual number of transmitted SSBs is 8, namely SSB#0, SSB#1, ……, SSB#7, and every 2 SSBs are associated with 1 RO. When multiple SSBs share one 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. Take Figure 4 RO#0 in

[0081] as an example. RO#0 has a total of 60 preambles, among which the preambles with indexes 0 to 29 are associated with SSB#0, and the preambles with indexes 30 to 59 are associated with SSB#1.

[0081] It should be noted that Figure 4 in

[0082] Before the UE sends PRACH, it first selects the SSB with the reference signal receiving power (RSRP) higher than the threshold according to the RSRP of the received beam; if the RSRPs of multiple SSBs are higher than the threshold, the terminal can select any SSB with the RSRP higher than the threshold; when there is no SSB with the RSRP higher than the threshold, the UE selects an SSB based on the implementation.

[0083] Based on the NW (Network) configuration, the UE obtains the correspondence between SSB and RO. After selecting an 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 to send PRACH / Preamble / Msg1.

[0084] Taking Figure 3 as an example, assume the UE selects SSB#1. The UE can select one of 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 RO (RO#0 or 4) associated with SSB#1 that is the closest available RO to the current time to send PRACH / Msg1. Among the selected ROs, the UE selects a preamble from the preamble set associated with the selected SSB to send PRACH. As Figure 4 shown, if one RO is associated with 2 SSBs, then in the set of available preambles associated with the SSB in one RO, the preambles will be divided into two subsets, each subset corresponding to one SSB. The UE will select a preamble from the preamble subset corresponding to the selected SSB for sending PRACH / Msg1.

[0085] (3) Determination of the RO set during PRACH retransmission.

[0086] PRACH retransmission is introduced in Rel-18 to enhance uplink coverage. For PRACH retransmission, the UE needs to retransmit the preamble on multiple ROs at different time domain positions associated with the same SSB, and the number of retransmissions can be {2, 4, 8}. After the UE determines the PRACH retransmission times, it needs to determine the RO set, and the number of valid ROs in the RO set is equal to the PRACH retransmission times. Assume the PRACH retransmission times is N, and the RO group determination rule is: first determine the starting RO of the RO group, and then determine the remaining N - 1 ROs of the RO group. The remaining N - 1 ROs of each RO group are the ROs that are associated with the same SSB as the starting RO, at the same frequency position, and have the same associated preamble set. For example, as Figure 5 shown, assume the PRACH retransmission times is 2. For SSB#0, first determine the starting RO of the RO group, and then determine the remaining 1 RO of the RO group. The remaining 1 RO of each RO group is the RO that is associated with the same SSB#0 as the starting RO, at the same frequency position, and has the same associated preamble set.

[0087] In a 5G network, the SSB configuration is configured by system information and the resource configuration of the SSB can only be changed through RRC reconfiguration information.

[0088] In addition, for different SSB indexes, their transmission periods and transmission powers are the same. And if an SSB index does not transmit in a certain period, it cannot transmit in other periods either, unless the system information is updated, then whether an SSB index transmits can be changed.

[0089] In this embodiment, considering different SSB indexes or SSB index groups, the load of the system may not be the same, that is, the resources required for the SSB need to be flexibly configured. In addition, for different SSB indexes or SSB index groups, their expected coverage ranges may also be different, and the corresponding required transmission powers are also different.

[0090] In view of this, the embodiments of the present application provide an SSB configuration method, which can improve the flexibility of SSB configuration.

[0091] It should be noted that for the SSB involved in the present application, it can also be called any module including at least one of a synchronization signal, a broadcast signal, a broadcast channel (PBCH), and a downlink broadcast channel for other system information.

[0092] In addition, for the reference signals involved in the present application, they 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 the reference signal of one cell or the reference signals of multiple cells, and the cells may have the same frequency carrier or different frequency carriers, and may be within a frequency band or different frequency bands.

[0093] Next, in conjunction with the accompanying drawings, the SSB configuration method provided by the embodiments of the present application will be described in detail through some embodiments and their application scenarios.

[0094] Figure 6 It is a schematic flowchart of the SSB configuration method 200 according to the embodiments of the present application.

[0095] As Figure 6As shown, the SSB configuration method 200 may include at least some of the following content:

[0096] S210, the terminal receives at least one SSB configuration from the network device:

[0097] Wherein, the at least one SSB configuration includes at least one of the following:

[0098] The first SSB configuration for configuring the resources of the SSB, the second SSB configuration for configuring the SSB for radio resource management (RRM) measurement, and the third SSB configuration for configuring the SSB transmission power;

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

[0100] The first configuration mode based on the SSB index, the second configuration mode based on the SSB index group, or the third configuration mode based on multiple first time units in the first time window.

[0101] In this embodiment, the resources of the SSB, the SSB for RRM measurement, or the SSB transmission power can be flexibly configured with the SSB index, the SSB index group, or the first time unit within the first time window as the granularity, avoiding the network configuring the same period and transmission power for different SSB indexes. That is, the flexibility of SSB configuration can be improved.

[0102] Specifically, considering different SSB indexes or SSB index groups, the load of the system may not be the same. In this embodiment, the resources of the SSB or the SSB for RRM measurement can be flexibly configured with the SSB index, the SSB index group, or the first time unit within the first time window as the granularity. In addition, considering that the reception performance of the SSB may be different for different SSB positions, time-domain diversity is required to improve the SSB performance. In addition, improving the position flexibility of the SSB is beneficial to the network scheduling other signals, especially in the scenarios where the scheduling signal is a periodic signal and the uplink subband is configured in the downlink time slot in the enhanced duplex mode.

[0103] Similarly, for different SSB indexes or SSB index groups, their expected coverage ranges may also be different, and the corresponding required transmission powers are also different. In this embodiment, the SSB transmission power can be flexibly configured with the SSB index, the SSB index group, or the first time unit within the first time window as the granularity, realizing a more flexible configuration of the SSB transmission power.

[0104] 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:

[0105] One SSB index corresponds to one or more SSBs;

[0106] The types or attributes of the SSBs corresponding to the same SSB index are the same;

[0107] Each SSB index is configured with an independent period;

[0108] The periods of different SSB indexes are in a multiple relationship or each period of an SSB index is a multiple of the minimum time unit;

[0109] The resource positions of the SSBs corresponding to the same SSB index within the period are fixed;

[0110] The resource positions of the SSBs corresponding to the same SSB index within the period are determined according to the first information, and the first information is configured by the network or agreed upon by the protocol;

[0111] The periods of different SSB indexes are the same, and some SSB indexes are deactivated within some periods of the second time window;

[0112] Different SSB indexes are configured with the same first period, and some SSB indexes are configured with a second period or correspond to multiple resource positions within the first period.

[0113] Exemplarily, one SSB index corresponds to one or more SSBs within one period.

[0114] 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.

[0115] Exemplarily, the periods of different SSB indexes can be the same or different.

[0116] Exemplarily, the minimum time unit can be a time unit configured by the network or a time unit agreed upon by the protocol. Or rather, the length of the minimum time unit can be configured by the network or agreed upon by the protocol.

[0117] Exemplarily, the minimum time unit is less than the period of any SSB index.

[0118] Exemplarily, the resource positions of the SSBs corresponding to the same SSB index within any one of its periods are fixed.

[0119] Exemplarily, the resource positions of the SSBs corresponding to the same SSB index within any one of its periods are determined according to the first information.

[0120] Exemplarily, the periods of different SSB indexes are the same, and some SSB indexes are deactivated during some periods within the second time window, which can also be understood or replaced as: the periods of different SSB indexes are the same, and some SSB indexes do not transmit or receive during some periods within the second time window.

[0121] Exemplarily, the second period is located within the first period, and the first period is a multiple of the second period.

[0122] In some embodiments, the first information is used to indicate the position of the SSB corresponding to the same SSB index within the time period of the cycle.

[0123] Exemplarily, the first information is used to indicate the position of the SSB corresponding to the same SSB index within the time period of any one of its cycles.

[0124] For example, assuming that the period of SSB0 is 20 ms, the first information is used to indicate which 5 ms within the 20 ms cycle the SSB corresponding to SSB0 is in. For example, the first information is 2 bits, and its values of 0, 1, 2, and 3 respectively represent the first, second, third, and fourth 5 ms.

[0125] 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:

[0236] In this embodiment, at least one of the following corresponding to the network configuration signaling is the same as or different from at least one of the following corresponding to the configured SSB: carrier, cell, band, BWP; equivalently, the network configuration signaling and the configured SSB may be on the same or different carriers, cells, bands, BWPs. Specifically, when the network configuration signaling and the configured SSB are on the same carrier, cell, 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, bands, or BWPs, the flexibility of the at least one SSB configuration can be improved.

[0237] The SSB configuration method provided by the present application will be described below in conjunction with specific embodiments.

[0238] Embodiment 1:

[0239] For different SSB indexes or SSB index groups, the load of the system is not necessarily the same, and the resources of the SSB need to be flexibly configured.

[0240] In some embodiments, the configuration of the time-frequency resources of the SSB is determined by one or more of the following methods:

[0241] Support the determination of SSB resources for each SSB index. That is, for different SSB indexes, independent determination of SSB time-frequency resources is introduced.

[0242] Optionally, one or more SSBs may correspond to one SSB index.

[0243] Optionally, these SSBs correspond to the same type / attribute (such as coverage requirement, waveform, etc.).

[0244] Support the configuration of SSB resources for each SSB index group. That is, for different SSB index groups, independent determination of SSB time-frequency resources is introduced.

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

[0246] Support the configuration of SSB resources based on the first time unit in the first time window. That is, independent or different SSB time-frequency resources are configured for different first time units in the first time window.

[0247] As a first sub - embodiment, the determination of SSB resources for each SSB index further includes one or more of the following methods:

[0248] 1. Each SSB index has an independent SSB period configuration.

[0249] 2. The SSB periods of different SSB indexes are in a multiple relationship or are multiples of a certain minimum time unit (such as 5 ms).

[0250] 3. The position of the same SSB index within the corresponding SSB period is fixed.

[0251] For example, configure 4 SSBs, namely SSB0, SSB1, SSB2, and SSB3. The period of SSB0 is 20 ms, the period of SSB1 is 40 ms, the period of SSB2 is 80 ms, and the period of SSB3 is 160 ms. To reduce the complexity of SSB search, the position of SSB0 within each 20 - ms period is fixed, the position of SSB1 within each 40 - ms period is fixed, the position of SSB2 within each 80 - ms period is fixed, and the position of SSB3 within each 160 - ms period is fixed.

[0252] 4. The position of the same SSB index within the corresponding SSB period is determined according to a certain pattern, and the pattern is specified by network configuration or protocol.

[0253] Considering that the reception performance of SSB may vary for different SSB positions, time - domain diversity is required to improve SSB performance. In addition, increasing the position flexibility of SSBs is beneficial for the network to schedule other signals, especially in the scenarios where the scheduled signal is a periodic signal and in the enhanced duplex mode for configuring the uplink sub - band in the downlink time slot.

[0254] For example, configure 4 SSBs, namely SSB0, SSB1, SSB2, and SSB3. The period of SSB0 is 20 ms, the period of SSB1 is 40 ms, the period of SSB2 is 80 ms, and the period of SSB3 is 160 ms.

[0255] Which 5 - ms within each 20 - ms period for SSB0 is determined by 2 bits. The values of the 2 bits being 0, 1, 2, 3 represent transmitting this SSB in the first, second, third, and fourth 5 - ms respectively.

[0256] Which 10 - ms within each 40 - ms period for SSB1 is determined by 2 bits. The values of the 2 bits being 0, 1, 2, 3 represent transmitting this SSB in the first, second, third, and fourth 10 - ms respectively.

[0257] Which 20 ms within each 80 ms of SSB2 is determined by 2 bits. The values of the 2 bits being 0, 1, 2, 3 indicate that the SSB is sent in the first, second, third, and fourth 20 ms respectively.

[0258] Which 40 ms within each 160 ms of SSB3 is determined by 2 bits. The values of the 2 bits being 0, 1, 2, 3 indicate that the SSB is sent in the first, second, third, and fourth 40 ms respectively.

[0259] 5. For SSB periods with the same SSB index configuration, some SSB indices are not sent during certain SSB periods.

[0260] To reduce the configuration complexity of the SSB period, it is possible to additionally configure whether certain SSB indices are sent during certain periods. Here, certain periods can be certain periods among multiple SSB periods within a time window.

[0261] For example, configure the SSB period to be 20 ms, and this time window includes 4 SSB periods (i.e., 80 ms); if the number of actually sent SSBs is configured to be 4, namely SSB indices 0, 1, 2, 3, an example of additionally configuring whether certain SSB indices are sent during certain periods is as follows:

[0262] SSB0 is sent in each 20 ms within every 80 ms;

[0263] SSB1 is sent in the 1st, 2nd, and 3rd 20 ms of every 80 ms and not sent in the 4th 20 ms;

[0264] SSB2 is sent in the 1st and 2nd 20 ms of every 80 ms and not sent in the 3rd and 4th 20 ms;

[0265] SSB3 is sent in the 1st 20 ms of every 80 ms and not sent in the 2nd, 3rd, and 4th 20 ms.

[0266] For example, the above configuration can be determined by introducing a 4-bit bitmap to decide in which 20 ms out of 4 20 ms the corresponding SSB index will be sent. The bitmap values corresponding to SSB0, SSB1, SSB2, SSB3 are {1111, 1110, 1100, 1000}, where the bit value 0 indicates not sent and 1 indicates sent.

[0267] 6. All SSB indexes are configured with the same SSB period, but some SSB indexes can be configured with additional periods or additional positions. Herein, the additional period can be understood as configuring multiple sub-periods within the SSB period. The additional position can be understood as adjusting the time-frequency domain positions of some SSB indexes additionally within the SSB period.

[0268] As a second sub-embodiment, the determination of SSB resources for each SSB index group further includes one or more of the following methods:

[0269] 1. The network configures one or more groups of SSB groups.

[0270] 2. Each SSB group has the same number of SSBs.

[0271] 3. Each SSB group has an independently configured number of SSBs.

[0272] 4. The SSB indexes of each SSB group are consecutive or determined according to a certain pattern.

[0273] 5. Each SSB index group has an independent SSB period configuration.

[0274] 6. The SSB periods of different SSB index groups are in a multiple relationship or multiples of a certain minimum time unit (such as 5 ms).

[0275] 7. The positions of the same SSB index group within the corresponding SSB period are fixed.

[0276] For example, configure 4 groups of SSBs, 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 20 ms, the period of {SSB4, SSB5, SSB6, SSB7} is 40 ms, the period of {SSB8, SSB9, SSB10, SSB11} is 80 ms, and the period of {SSB12, SSB13, SSB14, SSB15} is 160 ms. To reduce the complexity of SSB search, the positions of {SSB0, SSB1, SSB2, SSB3} are fixed within each 20 ms period, the positions of {SSB4, SSB5, SSB6, SSB7} are fixed within each 40 ms period, the positions of {SSB8, SSB9, SSB10, SSB11} are fixed within each 80 ms period, and the positions of {SSB12, SSB13, SSB14, SSB15} are fixed within each 160 ms period.

[0277] 8. The position of the same SSB index group within the period of the corresponding SSB group is determined according to a certain pattern, and the pattern is configured by the network or specified by the protocol.

[0278] Considering that the SSB positions within different SSB groups may vary in terms of the reception performance of the SSB, time-domain diversity is required to improve the SSB performance. Additionally, increasing the flexibility of the SSB positions within the SSB group can be beneficial for the network to schedule other signals, especially in scenarios where the scheduled signal is a periodic signal and the uplink sub-band is configured in the downlink time slot in the enhanced duplex mode.

[0279] For example, configure 4 SSB groups, 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 20 ms, the period of {SSB4, SSB5, SSB6, SSB7} is 40 ms, the period of {SSB8, SSB9, SSB10, SSB11} is 80 ms, and the period of {SSB12, SSB13, SSB14, SSB15} is 160 ms.

[0280] Which 5 ms within each 20 - ms period of {SSB0, SSB1, SSB2, SSB3} is determined by 2 bits. The values of the 2 bits being 0, 1, 2, 3 represent transmitting this SSB group in the first, second, third, and fourth 5 - ms respectively.

[0281] Which 10 ms within each 40 - ms period of {SSB4, SSB5, SSB6, SSB7} is determined by 2 bits. The values of the 2 bits being 0, 1, 2, 3 represent transmitting this SSB group in the first, second, third, and fourth 10 - ms respectively.

[0282] Which 20 ms within each 80 - ms period of {SSB8, SSB9, SSB10, SSB11} is determined by 2 bits. The values of the 2 bits being 0, 1, 2, 3 represent transmitting this SSB group in the first, second, third, and fourth 20 - ms respectively.

[0283] Which 40 ms within each 160 - ms period of {SSB12, SSB13, SSB14, SSB15} is determined by 2 bits. The values of the 2 bits being 0, 1, 2, 3 represent transmitting this SSB group in the first, second, third, and fourth 40 - ms respectively.

[0284] 9. All SSB index groups are configured with the same SSB period, and some SSB index groups do not transmit during certain SSB periods.

[0285] To reduce the configuration complexity of the SSB period, the same SSB period can be configured for all SSB groups, and it is additionally configured whether to transmit the SSBs of certain SSB index groups during certain periods. These certain periods can be some of the SSB periods within a time window.

[0286] For example, configure the SSB period to be 20 ms, and this time window includes 4 SSB periods (i.e., 80 ms); if the number of actually transmitted SSB groups is configured to be 4, and each group has four SSBs, which are SSB index groups {SSB0, SSB1, SSB2, SSB3}, {SSB4, SSB5, SSB6, SSB7}, {SSB8, SSB9, SSB10, SSB11}, {SSB12, SSB13, SSB14, SSB15}, examples of additionally configuring whether to transmit the SSBs of certain SSB index groups during certain periods are as follows:

[0287] {SSB0, SSB1, SSB2, SSB3} are transmitted in each 20 ms within every 80 ms;

[0288] {SSB4, SSB5, SSB6, SSB7} are transmitted in the 1st, 2nd, and 3rd 20 ms of every 80 ms and not transmitted in the 4th 20 ms;

[0289] {SSB8, SSB9, SSB10, SSB11} are transmitted in the 1st and 2nd 20 ms of every 80 ms and not transmitted in the 3rd and 4th 20 ms;

[0290] {SSB12, SSB13, SSB14, SSB15} are transmitted in the 1st 20 ms of every 80 ms and not transmitted in the 2nd, 3rd, and 4th 20 ms;

[0291] For example, the above configuration can be determined by introducing a 4-bit bitmap to decide in which 20 ms of the 4 20-ms periods the corresponding SSB index group will be transmitted. 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 the bit value 0 indicates that the corresponding SSB group is not transmitted in the corresponding 20 ms, and 1 indicates that the corresponding SSB group is transmitted in the corresponding 20 ms.

[0292] 10. All SSB index groups are configured with the same SSB period, but some SSB index groups can be configured with an (additional) period, or additional positions. Herein, the additional period can be understood as configuring multiple sub-periods within the SSB period. The additional position can be understood as additionally adjusting the time-frequency domain positions of some SSB index groups within the SSB period.

[0293] As a third sub-embodiment, the SSB resource configuration based on the first time unit in the first time window further includes one or more of the following methods:

[0294] 1. The network configures or the protocol stipulates the start time of the first time unit.

[0295] For example, the start time is SFN0, or HFN 0.

[0296] For example, the network configures or the protocol stipulates a time offset value for the start time of SFN0.

[0297] 2. The network configures the SSB resource patterns on different first time units within the first time window.

[0298] The SSB resource patterns can be configured according to different SSB indexes or according to different SSB index groups.

[0299] The first time window can be a periodic window. For example, it can take N first time units as a period, where N is configured by the network or stipulated by the protocol.

[0300] For example, the protocol stipulates that the first time unit is 640 ms, N = 2, that is, the first time window is 1280 ms. The network configures one SSB resource configuration pattern for every even 640 ms and another SSB resource configuration pattern for every odd 640 ms.

[0308] It should be noted that for intra-frequency / band cells, they are usually configured in different sectors. In this case, the same SSB resource configuration mode can be used to reduce the complexity of SSB search. The same applies to SSBs on different frequency bands within the same cell. For inter-frequency / band cells, they are usually configured in the same sector, and different SSB resource configuration modes can be configured to reduce the interference between SSBs.

[0320] 4. The configuration of SSB for RRM measurement is consistent with the method of SSB resource configuration (described in the previous embodiments).

[0321] In some embodiments, the network can configure SSB resources through one or more of the following methods:

[0322] System message;

[0323] Semi-static RRC signaling;

[0324] MAC-CE signaling;

[0325] DCI signaling.

[0326] It should be noted that the network configuration signaling and the configured SSB can be on the same or different carriers, cells, frequency bands, or bandwidth parts.

[0339] In some embodiments, the power configuration of the SSB may be a configuration of one or more of the following power offset values:
