Description

[Technical field]

[0001] The present invention relates to the technical field of communications. [Background technology]

[0002] Currently, New Radio (NR) systems can work in frequency bands within the following two frequency ranges (including FR1 and FR2), but do not yet support working in higher frequency bands.

[0003] [Table 1] Therefore, in the Rel-17 standardization, 3GPP is studying how to support NR to work in higher frequency bands (e.g., frequency bands in the 52.6-71 GHz frequency range). The above-mentioned higher frequency band range includes unlicensed (or shared) frequency bands.

[0004] In unlicensed (or shared) frequency bands, a transmitting device may need to perform channel sensing before transmitting and can transmit when it detects that the channel is idle, a mechanism called, for example, Listen Before Talk (LBT), on the one hand to protect the transmissions being made by other devices and to avoid interference, and on the other hand to ensure that the receiving device can receive correctly without interference.

[0005] In addition, in an NR system, a terminal device can perform measurements, such as measurements for radio resource management (RRM), measurements for radio link management (RLM), and measurements for channel state information (CSI) feedback, based on a synchronization signal block (SSB, Synchronization Signal Block, or SS / PBCH Block).

[0006] In order to support the terminal device to perform measurements based on SSB, a network device (e.g., a base station) can transmit SSB and transmit configuration information (also called measurement configuration) for SSB-based measurements to the terminal device. For example, the base station can indicate the time-frequency position of the SSB through the configuration information.

[0007] It should be noted that the introduction of the above background art is intended to clearly and completely explain the technical solutions of the present invention, and to facilitate understanding thereof by those skilled in the art, and these technical solutions are described in the background art of the present invention, and therefore should not be construed as being known to those skilled in the art. Summary of the Invention [Problem to be solved by the invention]

[0008] However, the inventor has found the following: In the case of cell reselection and connection state measurement, for an SSB at a certain frequency location, a network device (e.g., a base station) can transmit information for indicating an SSB waiting to be measured in an SMTC (SSB Measurement Timing Configuration) measurement duration by system information or dedicated Radio Resource Control (RRC) signaling. However, according to the current method, for an unlicensed frequency band, in some cases, the network device (base station) may not be able to indicate an SSB waiting to be measured in an SMTC measurement duration, which may greatly reduce the flexibility of network device configuration and greatly increase the complexity and power consumption of terminal device measurement.

[0009] In addition, in the case of idle and / or inactive state measurements, for SSBs at certain frequency locations, the network device can send information to indicate the SSBs waiting to be measured in the SMTC measurement period through system information or dedicated RRC signaling. However, according to the current method, for unlicensed frequency bands, in some cases, when the network device sends information to indicate the SSBs waiting to be measured in the SMTC measurement period, the terminal device may not be able to determine the SSBs waiting to be measured based on the information, so the terminal device may not be able to perform the corresponding measurements.

[0010] To address at least one of the above problems, embodiments of the present invention provide a measurement method and apparatus. [Means for solving the problem]

[0016] According to another aspect of an embodiment of the present invention, there is provided a measurement apparatus comprising: The present invention includes a receiving unit for receiving configuration information regarding an idle or inactive state of a network device transmission, wherein, when the configuration information is for an unlicensed frequency band, the configuration information does not include first indication information for indicating a synchronization signal block awaiting measurement. Effect of the Invention

Also, the terminal device can perform some measurements of the unlicensed (or shared) frequency band (e.g., measurements for idle or inactive states). This can improve the flexibility of the network device configuration, and thus can further reduce the complexity and power consumption of the terminal device during measurement.

[0022] The above and other features of the present invention will become apparent from the following detailed description and the accompanying drawings, in which: While the specification and drawings disclose certain embodiments of the present invention, these are merely illustrative of some of the embodiments which may employ the principles of the present invention, and it is to be understood that the present invention is not limited to the described embodiments, but rather includes all modifications, variations and alternatives which fall within the scope of the appended claims.

In addition, the term "base station" may include some or all of the functions thereof, and each base station can provide communication coverage for a specific geographical area. The term "cell" may refer to a base station and / or the area it covers, depending on the context of the term. In addition, the terms cell and base station may be interchangeable, as long as it does not cause confusion. In the embodiments of the present invention, the term "User Equipment" (UE) or "Terminal Equipment" (TE) refers to a device that accesses a communication network and receives services from the network, for example, via a network device. A User Equipment may be fixed or mobile, and may also be called a Mobile Station (MS), a terminal, a Subscriber Station (SS), an Access Terminal (AT), a station, etc.

[0027] Among these, user devices may include, but are not limited to, the following: cellular phones, personal digital assistants (PDAs), wireless modems, wireless communication devices, handheld devices, machine type communication devices, laptop computers, cordless telephones, smartphones, smart watches, digital cameras, etc.

[0028] Furthermore, for example, in a scenario such as IoT (Internet of Things), the terminal device may be an apparatus or device that further performs on-site monitoring or measurement, and may include, for example, an MTC (Machine Type Communication) terminal, an in-vehicle communication terminal, a D2D (Device to Device) terminal, an M2M (Machine to Machine) terminal, etc., but is not limited to these.

[0029] Furthermore, the term "network side" or "network device side" refers to one side of a network, which may be a specific base station or may include one or more network devices as described above. The term "user side" or "terminal side" or "terminal device side" refers to the user or terminal side, which may be a specific UE or may include one or more terminal devices as described above. Here, unless otherwise specified, "device" may refer to a network device or a terminal device.

[0030] Hereinafter, a scenario in an embodiment of the present invention will be described through an example, but the present invention is not limited thereto.

[0031] Fig. 1 is a diagram showing a communication system in an embodiment of the present invention, taking a terminal device and a network device as an example. As shown in Fig. 1, a communication system 100 may include a network device 101 and a terminal device 102. For convenience, Fig. 1 shows an example in which only one terminal device and only one network device are included, but the embodiment of the present invention is not limited to this.

[0032] In an embodiment of the present invention, existing services or future services can be performed between the network device 101 and the terminal device 102. These services include, but are not limited to, eMBB (enhanced Mobile Broadband), mMTC (massive Machine Type Communication), URLLC (Ultra-Reliable and Low-Latency Communication), etc.

[0033] In unlicensed (or shared) frequency bands, SSBs may not be able to transmit due to LBT failure. In NR Rel-16, to ensure coverage of unlicensed frequency bands for FR1 (410 MHz-7125 MHz), more candidate SSBs are predefined in one half frame (5 ms) compared to licensed frequency bands in the same frequency range (FR1). Specifically, when the SSB subcarrier spacing (SCS) is 15 kHz, the number of candidate SSBs is 10, and when the SSB SCS is 30 kHz, the number of candidate SSBs is 20.

[0034] For the predefined candidate SSBs in a half frame, the candidate SSB index of each candidate SSB and the DMRS sequence to be adopted during transmission are predefined.

[0035] Figure 2 shows an example of candidate SSBs predefined in a half frame when SCS is 15 kHz. As shown in Figure 2, the candidate SSBs correspond one-to-one to the candidate SSB indexes (0 to 9) according to the ascending order of symbols in the half frame. In other words, the candidate SSB index is used to represent the time domain position of the SSB in the half frame.

[0036] In addition, Fig. 2 also shows a simple correspondence between the candidate SSB indexes and the DMRS sequences to be adopted for the SSBs. Specifically, for the SSBs of one cell, the sequence of DMRSs in the SSBs with a particular candidate SSB index is determined based on the lowest three digits of the candidate SSB index. If the DMRS index (0 to 7) is used to represent different DMRS sequences generated based on the lowest three digits of the candidate SSB index, the correspondence between the candidate SSB indexes and the DMRS indexes is as shown in Fig. 2.

[0037] Figure 3 shows an example of candidate SSBs predefined in a half frame when SCS is 30 kHz. As shown in Figure 3, the candidate SSBs correspond one-to-one to the candidate SSB indexes (0 to 19) according to the ascending order of symbols in the half frame. In other words, the candidate SSB index is used to represent the time domain position of the SSB in the half frame.

[0038] Moreover, Fig. 3 also shows a simple correspondence between the candidate SSB indexes and the DMRS sequences to be adopted for the SSBs. Specifically, for an SSB of one cell, the sequence of DMRS in the SSB with a particular candidate SSB index is determined based on the lowest three digits of the candidate SSB index. If the DMRS index (0 to 7) is used to represent different DMRS sequences generated based on the lowest three digits of the candidate SSB index, the correspondence between the candidate SSB indexes and the DMRS indexes is as shown in Fig. 3.

[0039] In addition, SSBs may be transmitted employing beams, and for unlicensed frequency bands, to ensure coverage in each direction, within one discovery burst transmission window or half frame, the same direction may correspond to multiple candidate SSBs; or, it may be said that SSBs having different candidate SSB indices (or having different DMRS indices) may be QCLed.

[0040] For unlicensed frequency bands, the terminal device:

[0043]

[0044] [Table 2] In other words, the SSB index is used to represent the QCL relationship between SSBs. For SSBs with the same SSB index, the terminal device assumes that these SSBs are QCLed. According to the above calculation method, N SSB QCL Given the value of , the SSB index corresponding to the candidate SSBs predefined in the half frame can be uniquely determined.

[0045] Figure 4 shows the SSB SCS=15kHz and N SSB QCL FIG. 13 is a diagram showing an example of SSB indexes of candidate SSBs predefined in a half frame when SSB=8. According to the above calculation method, the numerical range of the SSB index is 0 to 7, and has a circular one-to-one correspondence with the candidate SSBs predefined in the half frame.

[0046] Figure 5 shows the SSB SCS=15kHz and NSSB QCL FIG. 2 is a diagram showing an example of SSB indexes of candidate SSBs predefined in a half frame when SSB=4. According to the above calculation method, the numerical range of the SSB index is 0 to 3, and has a circular one-to-one correspondence with the candidate SSBs predefined in the half frame.

[0047] Figure 6 shows the SSB SCS=15kHz and N SSB QCL FIG. 2 is a diagram showing an example of an SSB index of candidate SSBs predefined in a half frame when scalability is 1. According to the above calculation method, the SSB index has a numerical range of 0 to 1 and has a circular one-to-one correspondence with the candidate SSBs predefined in the half frame.

[0048] Figure 7 shows the SSB SCS=15kHz and N SSB QCL FIG. 13 is a diagram showing an example of an SSB index of candidate SSBs predefined in a half frame when SSB=1=0. According to the above calculation method, the numerical range of the SSB index is 0, which corresponds to the candidate SSBs predefined in a half frame.

[0049] Also, in the NR Rel-15 / Rel-16 system, the terminal device can perform measurements for RRM / RLM / CSI feedback based on SSB. To support the terminal device to perform measurements based on SSB, a network device (e.g., a base station) can transmit SSB and can transmit configuration information (or measurement configuration) for SSB-based measurements to the terminal device.

[0050] For example, for cell re-selection and measurement in connected state, the base station can transmit information about cell re-selection by SIB2, SIB3, and SIB4, and can transmit information about measurement in connected state by RRCReconfiguration (or RRCResume). In this information, for an SSB at a certain frequency position (the frequency position of the SSB is based on the position of the center frequency point of the SSB, for example), the base station can indicate an SSB waiting to be measured during the SMTC measurement duration by one information field (e.g., ssb-ToMeasure). For example, for an unlicensed frequency band of FR1, ssb-ToMeasure is indicated using mediumBitmap in SSB-ToMeasure.

[0051] For example, SSBs waiting to be measured during an SMTC measurement period (e.g., SMTC window duration) refer to SSBs that the terminal device may need to measure during the set SMTC measurement period, and the terminal device does not need to measure any SSBs other than the SSBs waiting to be measured as specified.

[0052] However, the inventor has found the following: According to the description of mediumBitmap in SSB-ToMeasure in the current protocol, for unlicensed frequency bands, on the one hand, one bit in the above-mentioned information field (which may be called ssb-ToMeasure or mediumBitmap) is used to indicate whether an SSB with the same SSB index in the SMTC measurement duration is an SSB waiting for measurement, and on the other hand, the value of the bit in the above-mentioned information field (which may be called ssb-ToMeasure or mediumBitmap) is restricted to a value indicated by an information field (ssb-PositionQCL) indicating the QCL relationship between SSBs.

[0053] However, in some cases, the above method may cause the network device (base station) to be unable to indicate the SSBs to be measured during the SMTC measurement duration by the above information field (ssb-ToMeasure or mediumBitmap). In addition, the above method may significantly reduce the flexibility of network / base station configuration and significantly increase the complexity and power consumption of UE measurements.

[0054] For example, in the case of intra-frequency cell reselection, inter-frequency cell reselection and connection state measurement, SIB3, SIB4 and RRCReconfiguration may include one or more ssb-PositionQCLs (configured in the manner of a list, and the list may include one or more ssb-PositionQCLs) for an SSB at a certain frequency position, respectively, or may not include an ssb-PositionQCL (i.e., ssb-PositionQCL is optional). The ssb-PositionQCL is cell-specific, in other words, one ssb-PositionQCL is for only one cell (labeled by PCI) that transmits an SSB at the frequency position, and when multiple ssb-PositionQCLs are included, different ssb-PositionQCLs are for different cells (each cell has a different PCI label) that transmit an SSB at the frequency position.

[0055] Also, in SIB3, SIB4 and RRCReconfiguration, ssb-ToMeasure is frequency specific, in other words, for an SSB at a certain frequency location, it contains only one ssb-ToMeasure, and the only one ssb-ToMeasure is for all measurement cells transmitting SSBs at that frequency location. If no ssb-ToMeasure is included, the UE needs to measure all SSBs in the SMTC measurement duration.

[0056] Considering the above two aspects, when two or more ssb-Position QCLs (each for a different cell) are to be included for an SSB at a certain frequency position, the network device and / or the terminal device cannot uniquely determine which ssb-Position QCL limits the bit value of the frequency-specific ssb-ToMeasure (or mediumBitmap). Correspondingly, the network device may not be able to accurately set the bit value of ssb-ToMeasure (or mediumBitmap), and the terminal device may not be able to determine whether the indication of ssb-ToMeasure matches the requirement, which may affect the terminal device's processing of this information (e.g., it may ignore the information). Therefore, in such a case, the network device (base station) may not be able to indicate the SSB waiting to be measured in the SMTC measurement duration by the above information field (ssb-ToMeasure or mediumBitmap).

[0057] In addition, ssb-PositionQCL is cell-specific, and ssb-ToMeasure is frequency-specific. Therefore, the above method may significantly reduce flexibility in network configuration.

[0058] On the other hand, in SIB3 and SIB4, when an ssb-PositionQCL is included for an SSB at a certain frequency position, the number of ssb-PositionQCL included is the same as the number of cells included in the neighbor cell list, and these ssb-PositionQCL(s) and the cells in the neighbor cell list should have a one-to-one correspondence according to the order in the list. Thus, in order to avoid the above-mentioned problem, since only one ssb-PositionQCL may be included for an SSB at a certain frequency position, the neighbor cell list also includes only one cell. This may limit the flexibility in network / base station configuration, and may also significantly increase the complexity and power consumption in terminal device measurements (the terminal device needs to blindly detect cells other than the neighbor cell list).

[0059] On the other hand, if an SSB at a certain frequency position contains one ssb-PositionQCL and the value indicated by this ssb-PositionQCL is 2, then according to the above method, only the most significant two digits of ssb-ToMeasure (or mediumBitmap) are valid, which limits the flexibility in network / base station configuration since for all cells transmitting SSBs at this frequency position, the SSBs waiting to be measured during the SMTC measurement duration are indicated based on only these two bits.

[0060] The inventor further discovered that, for now, the definition of the terminal device's capability of supporting idle / inactive measurement is based on frequency band (per FR). In other words, when the terminal device reports the terminal device's capability to a network device (e.g., a base station), it can report whether it supports idle / inactive measurement for FR1 and FR2, respectively. Since the unlicensed frequency band defined in Rel-16 belongs to a part of FR1, if the terminal device reports that it supports idle / inactive measurement for FR1, the network device may configure it to perform measurement in the unlicensed frequency band.

[0061] For now, for idle / inactive measurements, the network device can send information about idle / inactive measurements through SIB 4, SIB 11 and RRCRelease. In such information, for an SSB at a certain frequency location, the network device can indicate the SSBs waiting for measurement in the SMTC measurement duration through one information field (e.g., ssb-ToMeasure), but cannot indicate the QCL relationship between SSBs in SIB 11 and RRCRelease.

[0062] In addition, according to the above-mentioned method of indicating the SSB waiting for measurement by ssb-ToMeasure, for unlicensed frequency bands, the terminal device needs to determine the SSB waiting for measurement indicated by ssb-ToMeasure based on the QCL relationship between the SSBs indicated by the network device. Therefore, when the network device transmits ssb-ToMeasure by SIB 11 or RRCRelease to indicate the SSB waiting for measurement in the SMTC measurement duration, the terminal device may not be able to determine the SSB waiting for measurement at the corresponding frequency position based on the information determination, and therefore the terminal device may not be able to perform the corresponding measurement.

[0063] In view of at least one of the above problems, the following further describes an embodiment of the present invention. In the embodiment of the present invention, expressions such as "when", "in the case of", "for the case of" and "if" indicate that the information is based on one or more conditions or states, and these expressions are interchangeable. In addition, the "instruction" may explicitly include some information to notify, or may implicitly notify by some features.

[0064] In the following description, unless causing confusion, the terms "uplink control signal" and "uplink control information (UCI)" or "Physical Uplink Control Channel (PUCCH)" or "PUSCH transmission" are interchangeable, the terms "uplink data signal" and "uplink data information" or "Physical Uplink Shared Channel (PUSCH)" or "PUCCH transmission" are interchangeable, the terms "downlink control signal" and "downlink control information (DCI)" or "Physical Downlink Control Channel (PDCCH)" are interchangeable, and the terms "downlink data signal" and "downlink data information" or "Physical Downlink Shared Channel (PDSCH)" are interchangeable.

[0065] Also, the transmission or reception of a PUSCH may be understood as the transmission or reception of uplink data information carried by the PUSCH, the transmission or reception of a PUCCH may be understood as the transmission or reception of uplink control information carried by the PUCCH, the transmission or reception of a PRACH may be understood as the transmission or reception of a preamble carried by the PRACH, and the uplink signal may include an uplink data signal and / or an uplink control signal and / or an uplink reference signal and / or a random access channel, etc., and is also called an uplink transmission (UL transmission) or uplink information or uplink channel. Transmitting an uplink signal in an uplink resource may be understood as transmitting the uplink signal using the uplink resource.

[0066] Each implementation will be explained below.

[0067] <Example of the first aspect> In an embodiment of the present invention, a measurement method is provided, for example for cell reselection or connection state measurement.

[0068] 8 is a diagram illustrating a measurement method in an embodiment of the present invention. The description will be made from a terminal device and a network device. As shown in FIG. 8, the method includes the following steps (operations):

[0069] 801: A terminal device receives configuration information transmitted by a network device, the configuration information including first indication information for indicating synchronization signal blocks to be measured, in which one or more bits in the first indication information are set according to second indication information for indicating a QCL relationship between frequency-specific synchronization signal blocks and / or third indication information for indicating a QCL relationship between cell-specific synchronization signal blocks; and 802: The terminal device performs measurement based on a synchronization signal block waiting to be measured, which is indicated by the first indication information.

[0070] It should be noted that the above FIG. 8 is for illustrative purposes only and is not intended to limit the scope of the present invention. For example, the order of operations may be appropriately adjusted, or some operations may be added or removed. Those skilled in the art are not limited to the above description of FIG. 8 and may make appropriate modifications based on the above description.

[0071] In some embodiments, the above configuration information is for an unlicensed frequency band or a licensed frequency band, and the above first indication information, second indication information and third indication information are for, for example, SSBs at the same frequency location.

[0072] In some embodiments, the SSB waiting for measurement indicated by the first instruction information is an SSB waiting for measurement during the SMTC measurement duration. That is, the first instruction information is used to indicate an SSB waiting for measurement during the SMTC measurement duration. The SMTC measurement duration is, for example, set by the network device through RRC signaling. The terminal device performs measurement based on the SSB waiting for measurement during the SMTC measurement duration indicated by the first instruction information, and does not perform measurement based on other SSBs outside the SMTC measurement duration and other than the SSB indicated by the first instruction information to be waiting for measurement during the SMTC measurement duration.

[0073] In some embodiments, the first indication information is, for example, frequency-specific. In other words, for an SSB at a certain frequency location, the configuration information includes only one first indication information, and the only one first indication information applies to multiple cells that transmit SSB at the same frequency location.

[0074] In some embodiments, the second indication information is used to indicate the QCL relationship between frequency-specific synchronization signal blocks, and the third indication information is used to indicate the QCL relationship between cell-specific synchronization signal blocks, where the second indication information is frequency-specific and the third indication information is cell-specific.

[0075] In other words, for an SSB at a certain frequency location, the configuration information may include only one second instruction information, and the only second instruction information is applied to multiple cells transmitting an SSB at the same frequency location, and the configuration information may also include multiple third instruction information, and the only third instruction information is applied to only one cell transmitting an SSB at that frequency location.

[0076] For example, for an SSB at a certain frequency position, when the configuration information includes third indication information corresponding to a cell, the terminal device determines the QCL relationship between the synchronization signal blocks of the cell based on the third indication information, and for a cell for which the third indication information is not provided, the terminal device determines the QCL relationship between the synchronization signal blocks of the cell based on the second indication information.

[0077] In some embodiments, for an unlicensed frequency band, the above-mentioned configuration information necessarily includes second indication information.

[0078] In some embodiments, the frequency location of the SSB to be measured is determined, for example, by the frequency location of the SSB of the serving cell or is configured by RRC signaling. For example, for intra-frequency cell re-selection, the frequency location of the SSB to be measured is determined by the frequency location of the SSB of the serving cell, for inter-frequency cell re-selection, the frequency location is configured, for example, by dl-CarrierFreq included in SIB4, and for connection state measurement, the frequency location is configured, for example, by ssbFrequency included in measObjectNR.

[0079] In some embodiments, the first indication information is synchronization signal block measurement information (e.g., ssb-ToMeasure), the second indication information is synchronization signal block common QCL information (e.g., ssb-PositionQCL-Common), and the third indication information is synchronization signal block QCL information (e.g., ssb-PositionQCL).

[0080] For the unlicensed frequency band of FR1, ssb-ToMeasure can be indicated, for example, using a medium Bitmap in SSB-ToMeasure. For the unlicensed frequency band of a higher frequency band (e.g., FR2 or 52.6-71 GHz), ssb-ToMeasure can be indicated, for example, using a long Bitmap in SSB-ToMeasure.

[0081] Hereinafter, the synchronization signal block measurement information, the synchronization signal block common QCL information, and the synchronization signal block QCL information will be described as examples. The synchronization signal block measurement information is, for example, ssb-ToMeasure, but the present invention is not limited thereto, and may be, for example, ssb-ToMeasure-r16 or ssb-ToMeasure-r17; the synchronization signal block common QCL information is, for example, ssb-PositionQCL-Common, but the present invention is not limited thereto, and may be, for example, ssb-PositionQCL-Common-r16 or ssb-PositionQCL-Common-r17; and the synchronization signal block QCL information is, for example, ssb-PositionQCL, but the present invention is not limited thereto, and may be, for example, ssb-PositionQCL-cell, ssb-PositionQCL-r16, or ssb-PositionQCL-r17. The present invention does not limit the specific information name.

[0082] In some embodiments, one or more bits in the first indication information are set based on a value indicated by the second indication information. For example, one or more bits of the synchronization signal block measurement information (e.g., ssb-ToMeasure) are set based on the synchronization signal block common QCL information (ssb-PositionQCL-Common). In other words, the value of the bit of the first indication information (e.g., ssb-ToMeasure) is subject to the constraint of the synchronization signal block common QCL information (e.g., ssb-PositionQCL-Common).

[0083] In some embodiments, the Kth bit (K≧1) of the first indication information is set to 0, where K is greater than the value indicated by the second indication information.

[0084] In some embodiments, the number of synchronization signal blocks in the actual transmission of one cell is less than or equal to the number of 1 in the first indication information.

[0085] In some embodiments, the K=1 th bit in the first indication information is the left most bit.

[0086] For example, when the synchronization signal block common QCL information is set, the K-th bit in the first indication information is set to 0, where K is greater than the value of the synchronization signal block common QCL information. Furthermore, for example, the number of synchronization signal blocks actually transmitted by a specific cell is less than or equal to the number 1 in the first indication information.

[0087] Hereinafter, the first instruction information will be described by taking ssb-ToMeasure as an example. In addition, the first instruction information (ssb-ToMeasure) in the embodiment of the present invention is instructed using mediumBitmap in SSB-ToMeasure, but the present invention is not limited to this.

[0088] Table 2 is an example of a mediumBitmap description in SSB-ToMeasure.

[0089] [Table 3] Table 3 is another example of a mediumBitmap description in SSB-ToMeasure.

[0090] [Table 4] In some embodiments, the second instruction information and the third instruction information use SSB-PositionQCL-Relation to perform the instruction, and the numerical range thereof is, for example, {1, 2, 4, 8}. Table 4 is an example of SSB-PositionQCL-Relation.

[0091] [Table 5] In some embodiments, for cells in which the third indication information is not provided, the number of actually transmitted synchronization signal blocks is less than or equal to the number of bits with a value of 1 in the first indication information, and for cells in which the third indication information is provided, the number of actually transmitted synchronization signal blocks is less than or equal to the value indicated by the third indication information.

[0092] For example, when the synchronization signal block common QCL information is set, the K-th bit in the first indication information is set to 0, where K is greater than the value of the synchronization signal block common QCL information.Furthermore, for example, for a specific cell where synchronization signal block QCL information is not provided, the number of synchronization signal blocks actually transmitted is equal to or less than the number of bits whose value is 1 in the first indication information, and for a specific cell where synchronization signal block QCL information is provided, the number of synchronization signal blocks actually transmitted is equal to or less than the value of the synchronization signal block QCL information.

[0093] Table 5 is another example of a mediumBitmap description in SSB-ToMeasure.

[0094] [Table 6] In some embodiments, for cells in which the third indication information is not provided, the number of actually transmitted synchronization signal blocks is less than or equal to the value indicated by the second indication information, and for cells in which the third indication information is provided, the number of actually transmitted synchronization signal blocks is less than or equal to the value indicated by the third indication information.

[0095] In some embodiments, for a cell in which the third indication information is not provided, the number of actually transmitted synchronization signal blocks is less than the minimum of the value indicated by the second indication information and the number of bits in the first indication information whose value is 1, and for a cell in which the third indication information is provided, the number of actually transmitted synchronization signal blocks is less than the minimum of the value indicated by the third indication information and the number of bits in the first indication information whose value is 1.

[0096] In some embodiments, for a cell for which the third indication information is not provided, the number of actually transmitted synchronization signal blocks is less than or equal to the minimum of the value indicated by the second indication information and the number of bits in the first indication information that have a value of 1, and for a cell for which the third indication information is provided, the number of actually transmitted synchronization signal blocks is less than or equal to the minimum of the value indicated by the third indication information and the number of bits in the first indication information that have a value of 1 among the 1st to Mth bits, where M is the value indicated by the third indication information.

[0097] In some embodiments, for cells to which the third indication information is not provided, the number of actually transmitted synchronization signal blocks is less than or equal to the number of bits having a value of 1 in the first indication information, and for cells to which the third indication information is provided, the number of actually transmitted synchronization signal blocks is less than or equal to the minimum number of bits having a value of 1 among the 1st to Mth bits in the first indication information, where M is a value indicated by the third indication information.

[0098] Each piece of instruction information has been explained above, and the row (behavior) of the terminal device will be further explained below.

[0099] In some embodiments, for a cell for which third indication information is provided, the terminal device determines a corresponding relationship between the synchronization signal block and the synchronization signal block index (SSB index) based on the third indication information of the cell, and determines a synchronization signal block awaiting measurement of the cell based on the determined mapping relationship and the first indication information; and for a cell for which third indication information is not provided, the terminal device determines a mapping relationship between the synchronization signal block and the synchronization signal block index (SSB index) based on the second indication information, and determines a synchronization signal block awaiting measurement of the cell based on the determined mapping relationship and the first indication information.

[0100] For example, if ssb-PositionQCL is set for a cell, the terminal device obtains an SSB index based on ssb-PositionQCL, and then determines the SSB waiting to be measured for the cell based on ssb-ToMeasure; otherwise, it obtains an SSB index based on ssb-PositionQCL-Common, and then determines the SSB waiting to be measured for the cell based on ssb-ToMeasure.

[0101] 9 is a diagram showing an example of determining an SSB waiting for measurement in an embodiment of the present invention, in which SCS=15kHz, ssb-PositionQCL-Common=8, and ssB-ToMeasure=11000000.

[0102] As shown in Figure 9, ssb-PositionQCL is not set for cell 0, in which case, according to ssb-PositionQCL-Common=8, the SSB index is not restricted (still 0 to 7); and according to ssB-ToMeasure=11000000, the candidate SSBs corresponding to SSB index=0 or 1 in the cell are SSBs waiting for measurement (as shown in 900). That is, the numerical range of the SSB index is 0 to 7, with a circular one-to-one correspondence to the candidate SSBs predefined in the half frame.

[0103] As shown in Figure 9, ssb-PositionQCL=8 is set in cell 1, in which case, according to ssb-PositionQCL=8, the SSB index is not restricted (still ranges from 0 to 7); and according to ssB-ToMeasure=11000000, the candidate SSBs corresponding to SSB index=0 or 1 in the cell are SSBs waiting for measurement (as shown in 901).

[0104] As shown in Fig. 9, ssb-PositionQCL=4 is set in cell 2, in which case, according to ssb-PositionQCL=4, the SSB index is limited to four (0 to 3); and according to ssB-ToMeasure=11000000, the candidate SSBs corresponding to SSB index=0 or 1 in the cell are SSBs waiting for measurement (as shown in 902). That is, the numerical range of the SSB index is 0 to 3, and there is a circular one-to-one correspondence with the candidate SSBs predefined in the half frame.

[0105] As shown in Fig. 9, ssb-PositionQCL=2 is set in cell 3, where the SSB index is limited to two (0 to 1) according to ssb-PositionQCL=2; and according to ssB-ToMeasure=11000000, the candidate SSBs corresponding to SSB index=0 or 1 in the cell are SSBs waiting for measurement (as shown in 903). That is, the numerical range of the SSB index is 0 to 1, and there is a cyclic one-to-one correspondence with the candidate SSBs predefined in the half frame.

[0106] As shown in Fig. 9, ssb-PositionQCL=1 is set in cell 4, in which case, according to ssb-PositionQCL=1, the SSB index is limited to one (0); and according to ssB-ToMeasure=11000000, the candidate SSBs corresponding to SSB index=0 or 1 in the cell are SSBs waiting for measurement (as shown in 904). That is, the numerical range of the SSB index is 0, which corresponds to the candidate SSBs predefined in the half frame.

[0107] In some embodiments, for cells to which third indication information is provided and cells to which third indication information is not provided, the terminal device determines a first mapping relationship between a synchronization signal block and a synchronization signal block index (SSB index) based on the second indication information, and the terminal device determines a synchronization signal block waiting to be measured based on the first mapping relationship and the first indication information.

[0108] For example, the terminal device obtains an SSB index (eg, called a virtual SSB index) based on ssb-PositionQCL-Common, and then determines the SSB on which the cell needs to perform measurements based on ssb-ToMeasure.

[0109] 10 is a diagram showing another example of determining an SSB to be measured in an embodiment of the present invention, where SCS=15kHz, ssb-PositionQCL-Common=8, and ssB-ToMeasure=11000000.

[0110] As shown in FIG. 10, ssb-PositionQCL is not set for cell 0, and in this case, according to ssb-PositionQCL-Common=8, the virtual SSB index is 0 to 7 (corresponding to the first mapping relationship); and according to ssB-ToMeasure=11000000, the candidate SSB corresponding to SSB index=0 or 1 in the cell is an SSB waiting for measurement (as shown at 1000).

[0111] As shown in FIG. 10, ssb-PositionQCL=8 is set in cell 1, and in this case, according to ssb-PositionQCL=8, the SSB index is 0 to 7 (corresponding to the second mapping relationship); according to ssb-PositionQCL-Common=8, the virtual SSB index is 0 to 7 (corresponding to the first mapping relationship); and according to ssB-ToMeasure=11000000, the candidate SSB corresponding to SSB index=0 or 1 in the cell is an SSB waiting for measurement (as shown in 1001).

[0112] As shown in FIG. 10, ssb-PositionQCL=4 is set in cell 2, and in this case, according to ssb-PositionQCL=4, the SSB index is four (0 to 3) (corresponding to the second mapping relationship); according to ssb-PositionQCL-Common=8, the virtual SSB index is 0 to 7 (corresponding to the first mapping relationship); and according to ssB-ToMeasure=11000000, the candidate SSB corresponding to SSB index=0 or 1 in the cell is an SSB waiting for measurement (as shown in 1002).

[0113] As shown in FIG. 10, ssb-PositionQCL=2 is set in cell 3, and in this case, according to ssb-PositionQCL=2, the SSB index is two (0 to 1) (corresponding to the second mapping relationship); according to ssb-PositionQCL-Common=8, the virtual SSB index is 0 to 7 (corresponding to the first mapping relationship); and according to ssB-ToMeasure=11000000, the candidate SSB corresponding to SSB index=0 or 1 in the cell is an SSB waiting for measurement (as shown in 1003).

[0114] As shown in FIG. 10, ssb-PositionQCL=1 is set in cell 4, and in this case, according to ssb-PositionQCL=1, the SSB index is one (0) (corresponding to the second mapping relationship); according to ssb-PositionQCL-Common=8, the virtual SSB index is 0 to 7 (corresponding to the first mapping relationship); and according to ssB-ToMeasure=11000000, the candidate SSB corresponding to SSB index=0 or 1 in the cell is an SSB waiting for measurement (as shown in 1004).

[0115] Furthermore, for a cell for which third indication information is provided, the terminal device further determines a second mapping relationship between a synchronization signal block and a synchronization signal block index (SSB index) based on the third indication information of the cell, and performs measurements on the cell based on the second mapping relationship; and for a cell for which third indication information is not provided, the terminal device further performs measurements on the cell based on the first mapping relationship.

[0116] In some embodiments, the terminal device ignores the Kth bit of the first indication information, where for a cell to which the third indication information is provided, K is greater than the value indicated by the third indication information of the cell, and for a cell to which the third indication information is not provided, K is greater than the value indicated by the second indication information.

[0117] In some embodiments, one or more bits in the first indication information are set based on the maximum value indicated by the second indication information and the third indication information. For example, the Kth bit in the first indication information is set to 0, where K is the 1st indication information. two It is greater than the maximum value indicated by the instruction information and the third instruction information.

[0118] Table 6 is another example of a mediumBitmap description in SSB-ToMeasure.

[0119] [Table 7] Table 7 is another example of a mediumBitmap description in SSB-ToMeasure.

[0120] [Table 8] In some embodiments, one or more bits in the first indication information are not set according to the third indication information, for example, the first indication information is not defined as follows: when the third indication information is set, the Kth bit in the first indication information is set to 0, where K is greater than the maximum value indicated by the third indication information, and the number of synchronization signal blocks actually transmitted is less than or equal to the number of 1s in the first indication information.

[0121] Table 8 is another example of a mediumBitmap description in SSB-ToMeasure.

[0122] [Table 9] In some embodiments, the number of valid positions of the first indicating information in a particular cell is a predetermined value, for example eight.

[0123] In some embodiments, the configuration information is for cell reselection and the configuration information is carried in a system message, which may include, but is not limited to, one or any combination of the following: SIB2, SIB3, SIB4, etc. Alternatively, the configuration information is for connection state measurement and the configuration information is carried in Radio Resource Control (RRC) information, which may include, but is not limited to, MeasObjectNR, etc.

[0124] For example, ssb-ToMeasure may be included in one or any combination of the following information (elements or messages): RRCReconfiguration, measConfig, measObjectToAddModList, measObject, measObjectNR; for specific meanings, please refer to the related art.

[0125] The above-mentioned embodiments are provided to exemplify the embodiments of the present invention, but the present invention is not limited thereto, and furthermore, appropriate modifications can be made based on the above-mentioned embodiments. For example, the above-mentioned embodiments may be used alone, or a plurality of the above-mentioned embodiments may be combined.

[0126] As can be seen from the above embodiment, one or more bits in the first indication information for indicating synchronization signal blocks waiting for measurement are set based on the second indication information for indicating QCL relationship between frequency-specific synchronization signal blocks and / or the third indication information for indicating QCL relationship between cell-specific synchronization signal blocks, so that for some measurements of unlicensed (or shared) frequency bands (e.g., cell reselection measurement and connection state RRM measurement), the terminal device can accurately understand the measurement information. This can improve the flexibility of network device configuration, and thus can further reduce the complexity and power consumption of terminal device measurements.

[0127] <Example of the second aspect> In the embodiments of the present invention, a measurement method is provided, which will be further described based on the embodiments of the first aspect. Here, the description of the same contents as those of the embodiments of the first aspect will be omitted. The embodiments of the second aspect can be combined with the embodiments of the first aspect, or can be implemented alone.

[0128] In some embodiments, the terminal device receives configuration information transmitted by a network device, the configuration information including first indication information for indicating a synchronization signal block waiting to be measured that is dedicated to a cell and third indication information for indicating a QCL relationship between the synchronization signal blocks dedicated to the cell, wherein one or more bits in the first indication information are set based on the third indication information; and the terminal device performs measurements based on the synchronization signal blocks waiting to be measured that are indicated by the first indication information.

[0129] In some embodiments, the first indication information is cell-specific synchronization signal block measurement information (ssb-ToMeasure), and the third indication information is synchronization signal block QCL information (e.g., ssb-PositionQCL), and one or more bits in the cell-specific synchronization signal block measurement information (ssb-ToMeasure) are set according to the synchronization signal block QCL information (e.g., ssb-PositionQCL).

[0130] For example, when the cell-specific third indication information (e.g., ssb-PositionQCL) is set, the cell-specific first indication information (cell specific ssb-ToMeasure) is set. That is, the cell-specific first indication information (cell specific ssb-ToMeasure) is increased, and the information and the cell-specific third indication information (ssb-PositionQCL) are set together.

[0131] In some embodiments, when the setting information includes second indication information (e.g., ssb-PositionQCL-Common) for indicating the QCL relationship between frequency-specific synchronization signal blocks, a bit in the first indication information is further set based on the second indication information.

[0132] For example, when cell-specific first instruction information (cell specific ssb-ToMeasure) and cell-specific third instruction information (ssb-PositionQCL) are set for a specific cell, the SSB waiting for measurement is determined based on these two pieces of cell-specific information; when frequency-specific first instruction information (frequency specific ssb-ToMeasure) and frequency-specific second instruction information (ssb-PositionQCL-Common) are set, the SSB waiting for measurement is determined based on these two pieces of frequency-specific information.

[0133] In some embodiments, the terminal device receives configuration information transmitted by a network device, the configuration information including first indication information for indicating synchronization signal blocks awaiting measurement, in which values ​​indicated by third indication information for indicating QCL relationships between cell-specific synchronization signal blocks of multiple cells are the same; one or more bits in the first indication information are set based on values ​​indicated by the third indication information; and the terminal device performs measurements based on the synchronization signal blocks awaiting measurement indicated by the first indication information.

[0134] For example, for multiple cells, the third indication information (e.g., ssb-PositionQCL) for indicating the QCL relationship between cell-specific synchronization signal blocks all indicate the same value (e.g., 4), in which case one or more bits of the first indication information (e.g., ssb-ToMeasure) are set based on the same value (e.g., 4).

[0135] In some embodiments, when the configuration information includes second indication information (ssb-PositionQCL-Common) for indicating the QCL relationship between frequency-specific synchronization signal blocks but does not include third indication information (ssb-PositionQCL) for indicating the QCL relationship between cell-specific synchronization signal blocks, the bits in the first indication information are set based on the second indication information (ssb-PositionQCL-Common).

[0136] In some embodiments, the number of valid positions in the first indication is a predetermined value, for example eight.

[0137] The above-mentioned embodiments are provided to exemplify the embodiments of the present invention, but the present invention is not limited thereto, and furthermore, appropriate modifications can be made based on the above-mentioned embodiments. For example, the above-mentioned embodiments may be used alone, or a plurality of the above-mentioned embodiments may be combined.

[0138] <Example of the third aspect> In the embodiments of the present invention, a measurement method is provided, and will be described based on the embodiments of the first and second aspects. Here, the description of the same contents as the embodiments of the first and second aspects will be omitted. The embodiment of the third aspect is related to the measurement of an idle state or an inactive state, and can be combined with the embodiments of the first and second aspects, or can be implemented alone.

[0139] In some embodiments, the terminal device receives configuration information transmitted by a network device, in which the configuration information includes first indication information for indicating synchronization signal blocks awaiting measurement, and second indication information for indicating a QCL relationship between frequency-specific synchronization signal blocks and / or third indication information for indicating a QCL relationship between cell-specific synchronization signal blocks; and the terminal device performs measurements based on the synchronization signal blocks awaiting measurement indicated by the first indication information.

[0140] In some embodiments, the network device may send measurement configuration information for an idle or inactive state via SIB4, SIB11 and RRCRelease.

[0141] In some embodiments, the first instruction information is synchronization signal block measurement information (ssb-ToMeasure), the second instruction information is synchronization signal block common QCL information (ssb-PositionQCL-Common), and the third instruction information is synchronization signal block QCL information (ssb-PositionQCL), but the present invention is not limited thereto.

[0142] For example, the configuration information may include synchronization signal block measurement information (ssb-ToMeasure) and synchronization signal block common QCL information (ssb-PositionQCL-Common); or the configuration information may include synchronization signal block measurement information (ssb-ToMeasure) and synchronization signal block QCL information (ssb-PositionQCL); or the configuration information may include synchronization signal block measurement information (ssb-ToMeasure), synchronization signal block common QCL information (ssb-PositionQCL-Common), and synchronization signal block QCL information (ssb-PositionQCL).

[0143] In some embodiments, the configuration information for the idle or inactive state is carried in, for example, a MeasIdConfig, MeasIdleCarrierNR or ssb-MeasConfig message, but the present invention is not limited thereto. If the configuration information is for an unlicensed frequency band, when the configuration information includes the first indication information, the configuration information necessarily includes the third indication information.

[0144] Furthermore, the terminal device can determine the SSBs waiting to be measured at the corresponding frequencies based on the embodiments of the first and second aspects.

[0145] In some embodiments, one or more bits of the synchronization signal block measurement information (ssb-ToMeasure) are set based on the synchronization signal block common QCL information (ssb-PositionQCL-Common).

[0146] In some embodiments, the Kth bit in the first indication information is set to 0, where K is greater than the value indicated by the second indication information, and the number of synchronization signal blocks actually transmitted by a cell is less than or equal to the number of 1s in the first indication information.

[0147] In some embodiments, for cells for which the third indication information is not provided, the number of actually transmitted synchronization signal blocks is less than or equal to the number of 1s in the first indication information, and for cells for which the third indication information is provided, the number of actually transmitted synchronization signal blocks is less than or equal to the value indicated by the third indication information.

[0148] In some embodiments, for cells in which the third indication information is not provided, the number of actually transmitted synchronization signal blocks is less than or equal to the value indicated by the second indication information, and for cells in which the third indication information is provided, the number of actually transmitted synchronization signal blocks is less than or equal to the value indicated by the third indication information.

[0149] In some embodiments, for a cell for which the third indication information is provided, the terminal device determines a mapping relationship between a synchronization signal block and a synchronization signal block index (SSB index) based on the third indication information of the cell, and determines a synchronization signal block awaiting measurement for the cell based on the determined mapping relationship and the first indication information; and for a cell for which the third indication information is not provided, the terminal device determines a mapping relationship between a synchronization signal block and a synchronization signal block index (SSB index) based on the second indication information, and determines a synchronization signal block awaiting measurement for the cell based on the determined mapping relationship and the first indication information.

[0150] In some embodiments, for a cell to which the third indication information is provided and a cell to which the third indication information is not provided, the terminal device determines a first mapping relationship between a synchronization signal block and a synchronization signal block index (SSB index) based on the second indication information, and the terminal device determines a synchronization signal block waiting to be measured based on the first mapping relationship and the first indication information.

[0151] In some embodiments, for a cell for which the third indication information is provided, the terminal device further determines a second mapping relationship between a synchronization signal block and a synchronization signal block index (SSB index) based on the third indication information of the cell, and performs measurements on the cell based on the second mapping relationship; and for a cell for which the third indication information is not provided, the terminal device further performs measurements on the cell based on the first mapping relationship.

[0152] In some embodiments, the terminal device ignores the Kth bit of the first indication information, where for a cell to which the third indication information is provided, K is greater than the value indicated by the third indication information of the cell, and for a cell to which the third indication information is not provided, K is greater than the value indicated by the second indication information.

[0153] In some embodiments, one or more bits in the first indication information are set based on the maximum value indicated by the second indication information and the third indication information. For example, the K-th bit in the first indication information is set to 0, where K is the maximum value indicated by the second indication information and the third indication information. two It is greater than the maximum value indicated by the instruction information and the third instruction information.

[0154] The above describes a case where the configuration information of idle / inactive measurement includes the first instruction information, and the second instruction information and / or the third instruction information. As a result, the configuration information of idle / inactive measurement includes not only the first instruction information (e.g., ssb-ToMeasure) for instructing measurement, but also the third instruction information (e.g., ssb-PositionQCL) or the second instruction information (ssb-PositionQCL-Common) for instructing the QCL relationship between SSBs. As a result, the terminal device can accurately understand the measurement information (e.g., ssb-ToMeasure), and can perform some measurements (e.g., measurements in the idle state and / or the inactive state) for the unlicensed (or shared) frequency band.

[0155] In some embodiments, the terminal device receives configuration information transmitted by a network device, and when the configuration information is for an unlicensed frequency band, the configuration information does not include first indication information for indicating a synchronization signal block to be measured. Further, the terminal device determines all synchronization signal blocks as synchronization signal blocks to be measured.

[0156] For example, for an unlicensed frequency band, MeasIdConfig, MeasIdleCarrierNR or ssb-MeasConfig does not include ssb-ToMeasure, and the SSBs waiting for measurement are all SSBs.

[0157] As a result, the configuration information for idle / inactive measurement does not include first instruction information (e.g., ssb-ToMeasure), and the terminal device does not need to accurately understand the first instruction information information (e.g., ssb-ToMeasure) for the measurement, so it can use a default SSB (e.g., all SSB), thereby making it possible to perform some measurements (e.g., measurements in idle and / or inactive states) for unlicensed (or shared) frequency bands.

[0158] In some embodiments, the terminal device receives configuration information transmitted by a network device, wherein the configuration information includes first indication information for indicating a synchronization signal block waiting to be measured; and the terminal device determines a mapping relationship between the synchronization signal block and a synchronization signal block index (SSB index) based on a predetermined value, and determines the synchronization signal block waiting to be measured based on the determined mapping relationship and the first indication information.

[0159] For example, the predetermined value is 8. Set ssb-PositionQCL-Common=8 and / or ssb-PositionQCL=8, thereby determining the SSBs waiting to be measured indicated by the SSB index and ssb-ToMeasure.

[0160] As a result, the configuration information for idle / inactive measurement includes the first indication information (e.g., ssb-ToMeasure). Even if the third indication information (e.g., ssb-PositionQCL) or the second indication information (ssb-PositionQCL-Common) for indicating the QCL relationship between SSBs is not included, the terminal device can accurately understand the first indication information (e.g., ssb-ToMeasure) for the measurement based on a predetermined value, and can thereby perform some measurements (e.g., measurements in the idle state and / or the inactive state) for the unlicensed (or shared) frequency band.

[0161] In some embodiments, the terminal device may further transmit capability report information to the network device, the capability report information being used to report whether the terminal device supports performing idle or inactive measurements in the unlicensed frequency band.

[0162] For example, considering that idle / inactive measurements on unlicensed frequency bands may be supported in the future, new UE capability report information may be introduced in subsequent releases. For example, the new UE capability information may be used to report whether idle / inactive measurements on unlicensed frequency bands are supported. If supported, the base station may configure the UE to perform measurements on unlicensed frequency bands in the corresponding frequency range, and the SSBs waiting for measurement are indicated and determined according to any one or more of the above embodiments; otherwise, the base station does not configure the UE to perform idle / inactive measurements on unlicensed frequency bands.

[0163] Alternatively, the definition of UE capability of supporting idle / inactive measurements is still per FR. For a Rel-16 UE, even if the UE reports that it supports idle / inactive measurements in FR1, the base station will not configure the UE to perform idle / inactive measurements in unlicensed frequency bands. For a later release UE, if the UE reports that it supports idle / inactive measurements in FR1 and / or FR2, the base station can configure the UE to perform measurements in unlicensed frequency bands in the corresponding frequency ranges, and the SSBs pending measurements are indicated and determined according to any one or more of the embodiments described above.

[0164] As can be seen from the above embodiment, the terminal device can perform some measurements (e.g., measurements in idle or inactive states) on the unlicensed (or shared) frequency band, which can improve the flexibility of the network device configuration and thus further reduce the complexity and power consumption of the terminal device measurements.

[0165] <Example of the fourth aspect> An embodiment of the present invention provides a BWP setting method, which can be combined with the embodiments of the first to third aspects, or can be implemented alone.

[0166] In some embodiments, the network device can configure the BWP by UE-specific RRC signaling. For example, in an RRC-Reconfiguration message, the network device can configure the BWP for one or more cells, respectively. The BWP configuration information includes an information field (e.g., subcarrierSpacing) for indicating the subcarrier spacing of the BWP. For an initial DL BWP, the value of the information field should be the same as subCarrierSpacingCommon in the MIB. However, for unlicensed frequency bands in FR1, this limits the network deployment (or network deployment flexibility).

[0167] For example, for an unlicensed frequency band in FR1, subCarrierSpacingCommon in the MIB is N SSB QCL This is used to indicate the value of QCL between SSBs, as shown in the following table:

[0168] Table 4.1-1:Mapping between the combination of subCarrierSpacingCommon and LSB of ssb-SubcarrierOffset to N SSB QCL

[0169] [Table 10] However, for FR1, when viewed from the angle indicating the SCS, if the value of subCarrierSpacingCommon is scs15 or 60, it indicates that the SCS is 15 kHz, and if the value of subCarrierSpacingCommon is scs30 or 120, it indicates that the SCS is 30 kHz. Therefore, according to the above method, the following combinations of settings 3, 4, 5, and 6 cannot be indicated.

[0170] [Table 11] The flexibility of the above configuration for unlicensed frequency bands can be improved in the following manner.

[0171] In some embodiments, for an initial DL BWP in an unlicensed frequency band (e.g., FR1) (for operation with shared spectrum channel access), the value of subcarrierSpacing corresponds to the SCS of the SSB associated to the initial DL BWP, which can be written as "For the initial DL BWP this field has the value corresponding to the subcarrier spacing of the SSB associated to the initial DL BWP for operation with shared spectrum channel access".

[0172] In some embodiments, for an initial DL BWP of an unlicensed frequency band (for operation with shared spectrum channel access), the value of subcarrierSpacing is a value corresponding to the SCS of CORESET#0 configured by the initial DL BWP.

[0173] In some embodiments, for an initial DL BWP in an unlicensed frequency band (for operation with shared spectrum channel access), the value of subcarrierSpacing is a value that corresponds to the SCS of the cell-defining SSB of the cell.

[0174] In some embodiments, for an initial DL BWP in an unlicensed frequency band (for operation with shared spectrum channel access), the value of subcarrierSpacing is a value corresponding to the SCS of the SSB of the cell.

[0175] For example, the SCS of SSBs transmitted by the same cell is the same.

[0176] In some embodiments, for an initial DL BWP in an unlicensed frequency band (for operation with shared spectrum channel access), the value of subcarrierSpacing is a value corresponding to the SCS of the SSB of the cell.

[0177] For example, the SCS of SSBs transmitted by the same cell is the same.

[0178] In some embodiments, the value of subcarrierSpacing is a value corresponding to Subcarrier spacing for SIB1 and / or a value corresponding to Msg.2 / 4 for initial access, paging and broadcast SI-messages.
