Detailed Description

In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

It should be understood that the technical solution of the embodiment of the present application may be applied to a 5G system, or a New Radio (NR) system.

In the embodiment of the present application, the Terminal device may include, but is not limited to, a Mobile Station (MS), a Mobile Terminal (Mobile Terminal), a Mobile phone (Mobile Telephone), a User Equipment (UE), a handset (handset), a portable device (portable Equipment), a vehicle (vehicle), and the like, and the Terminal device may communicate with one or more core networks through a Radio Access Network (RAN), for example, the Terminal device may be a Mobile phone (or referred to as a "cellular" phone), a computer with a wireless communication function, and the Terminal device may also be a portable, pocket, handheld, computer-embedded, or vehicle-mounted Mobile apparatus.

The network device according to the embodiment of the present application is a device deployed in a radio access network to provide a wireless communication function for a terminal device. The network device may be a base station, and the base station may include various macro base stations, micro base stations, relay stations, access points, and the like. In systems employing different radio access technologies, the names of devices having a base station function may differ. For example, in an LTE network, referred to as an evolved node B (eNB or eNodeB), in a third Generation (3rd Generation, 3G) network, referred to as a node B (node B), and so on.

In the embodiment of the present invention, a Synchronization Signal Block (SSB) is composed of two parts, namely, a Synchronization Signal and a Physical Broadcast Channel. The Synchronization Signal is divided into a Primary Synchronization Signal (PSS) and a Secondary Synchronization Signal (SSS). The PBCH is used for a terminal device to obtain a Master Information Block (MIB), which also carries Downlink (DL) parameter set (Numerology) Information, and configuration Information of RMSI CORESET (DLNumerology Information) used for indicating Numerology for transmitting Remaining Minimum System Information (RMSI), Message2 and Message4 for initial access, and Other System Information (OSI) for broadcasting.

In the embodiment of the present application, the parameters in Numerology include a subcarrier spacing and a Cyclic Prefix (CP) length.

In the embodiment of the present application, the maximum number of SSBs that can be included in one SS Burst Set (Burst Set) is related to the carrier frequency used by the communication system. Generally, when the carrier frequency is less than 3GHz, a maximum of 4 SSBs can be included in one SS Burst Set. The carrier frequency is 3GHz to 6GHz, and a maximum of 8 SSBs can be contained in one SS Burst Set. When the carrier frequency is above 6GHz, a maximum of 64 SSBs can be contained in one SS Burst Set. However, no matter how many SSBs are included in an SS Burst Set, the SSBs need to be transmitted within a transmission Time Window (Time Window) of the SSBs. Here, the SSB transmission time window may be, for example, 5 ms.

In the embodiment of the present application, the Multiplexing mode is a Time Division Multiplexing (TDM) mode or a Frequency Division Multiplexing (FDM) mode. In the embodiment of the present application, the other signal refers to a signal which is not a synchronization signal block and is transmitted by multiplexing with the synchronization signal block, or is understood as a symbol used for transmitting the other signal as a symbol multiplexed with a symbol transmitting the synchronization signal block.

Fig. 1 illustrates a method for transmitting a synchronization signal block according to one embodiment of the present application. As shown in fig. 1, the method 100 includes:

s110, a first parameter set used for transmitting the synchronization signal block is determined.

And S120, determining a second parameter set used for transmitting other signals.

It should be noted that in S120, other signals include, but are not limited to, an uplink control signal, a downlink control signal, a guard interval, and a data signal.

S130, when it is determined to transmit the synchronization signal block and the other signals in the multiplexing mode, determining a transmission Pattern (Pattern) of the synchronization signal block according to the first parameter set and the second parameter set.

Alternatively, in S130, the transmission pattern of the synchronization signal block is used to describe a candidate position of the time domain position occupied by the synchronization signal block.

Optionally, in some embodiments, when it is determined that the subcarrier interval corresponding to the first parameter set is 30kHz and the subcarrier interval corresponding to the second parameter set is 15kHz, determining the transmission pattern of the synchronization signal block as a first pattern in which the candidate positions of the time domain position occupied by the synchronization signal block are the 9 th to 12 th symbols of the first time slot corresponding to the first parameter set and the 3rd to 6 th symbols of the second time slot corresponding to the first parameter set; the first time slot and the second time slot are adjacent time slots, and the first 2 symbols of the first time slot can adopt a second parameter set to transmit downlink control signals.

It should be noted that, the candidate positions of the time domain position occupied by the synchronization signal block are the 9 th to 12 th symbols of the first time slot corresponding to the first parameter set and the 3rd to 6 th symbols of the second time slot corresponding to the first parameter set, it can be understood that the 9 th to 12 th symbols of the first time slot or the 3rd to 6 th symbols of the second time slot may be selected to transmit the synchronization signal block, and the 9 th to 12 th symbols of the first time slot and the 3rd to 6 th symbols of the second time slot may be selected to transmit the synchronization signal block.

For example, as shown in fig. 2, the subcarrier spacing for the first set of parameters is 30kHz, the subcarrier spacing for the second set of parameters is 15kHz, symbols 8-11 on the first slot corresponding to 30kHz in fig. 2 are selected for transmission of SSB1, symbols 2-5 on the second slot corresponding to 30kHz in fig. 2 are selected for transmission of SSB2, and symbol 0 corresponding to 15kHz is used for transmission of downlink control signals. In fig. 2, DL represents downlink control, UL represents uplink control, and GP represents a guard interval.

Optionally, in other embodiments, when the subcarrier spacing corresponding to the first parameter set is determined to be 30kHz and the subcarrier spacing corresponding to the second parameter set is determined to be 15kHz, the transmission Pattern of the synchronization signal block is determined to be Pattern1 in the related art. As shown in fig. 3, in Pattern1, the first 4 symbols of the first slot are reserved for downlink control, the last 2 symbols of the first slot are reserved for guard interval and uplink control, the first 2 symbols of the second slot are reserved for downlink control, the last 4 symbols of the second slot are reserved for guard interval and uplink control, the candidate positions of the time domain positions occupied by the synchronization signal block are the 5 th to 8 th symbols and the 9 th to 12 th symbols of the first slot, and the 3rd to 6 th symbols and the 7 th to 10 th symbols of the second slot.

Specifically, in some embodiments, the transmission pattern of the synchronization signal blocks is a first pattern, one SS Burst Set includes M synchronization signal blocks, M is a positive integer less than or equal to 4, and the method 100 further includes: determining candidate positions of the first time slot as a first time slot and a third time slot in a sending time window of the synchronous signal block; and determining the candidate position of the second time slot as the second time slot and the fourth time slot in the sending time window. Optionally, in a case where the network device and the terminal device communicate via a carrier less than 3GHz, the number of synchronization signal blocks in one SS Burst Set is less than or equal to 4.

That is, if the transmission pattern of the synchronization signal block is the first pattern, when M synchronization signal blocks need to be transmitted, M slots may be selected from the candidate position of the first slot and the candidate position of the second slot in the transmission time window of the synchronization signal block for transmitting the M synchronization signal blocks, for example, the first M slots may be selected for transmitting the M synchronization signal blocks.

For example, fig. 4 shows that when the transmission pattern of the SSB is the first pattern shown in fig. 2 and 4 SSBs are included in one SS Burst Set, the slot for transmitting the SSB is the first 4 slots (the slot filled with oblique lines in fig. 4) in the transmission time window with the length of 5 ms.

Specifically, in other embodiments, the transmission pattern of the synchronization signal blocks is a first pattern, an SS Burst Set includes N synchronization signal blocks, N is a positive integer less than or equal to 8, and the method 100 further includes: determining candidate positions of a first time slot as a first time slot, a third time slot, a fifth time slot and a seventh time slot in a sending time window of the synchronous signal block; and determining candidate positions of the second time slot as the second time slot, the fourth time slot, the sixth time slot and the eighth time slot in the sending time window. Optionally, when the frequency of the carrier used in the communication between the network device and the terminal device is between 3GHz and 6GHz, the number of the synchronization signal blocks included in one SS Burst Set is less than or equal to 8.

That is, if the transmission pattern of the synchronization signal block is the first pattern, when N synchronization signal blocks need to be transmitted, N slots may be selected for transmitting the N synchronization signal blocks from among a candidate position of the first slot and a candidate position of the second slot in a transmission time window of the synchronization signal block. For example, N synchronization signal blocks may be transmitted over the first N slots in a transmission time window of the synchronization signal blocks.

For example, fig. 5 shows that when the transmission pattern of the SSB is the first pattern shown in fig. 2 and 8 SSBs are included in one SS Burst Set, the slot for transmitting the SSB is the first 8 slots (the slot filled with oblique lines in fig. 5) in the transmission time window with the length of 5 ms.

Optionally, in some embodiments, when it is determined that the subcarrier interval corresponding to the first parameter set is 30kHz and the subcarrier interval corresponding to the second parameter set is 15kHz, the transmission pattern of the synchronization signal block is determined to be a second pattern, in the second pattern, the candidate positions of the time domain position occupied by the synchronization signal block are the 3rd to 6 th symbols and the 9 th to 12 th symbols of the third time slot corresponding to the first parameter set, and the first 2 symbols of the third time slot can transmit the downlink control signal by using the second parameter set.

Fig. 6 shows a second pattern in which candidate positions of a time domain position occupied by an SSB are symbols 2 to 5 and symbols 8 to 11 of one slot corresponding to 30kHz, and symbol 0 corresponding to 15kHz is used for transmitting a downlink control signal according to an embodiment of the present application.

Specifically, in some embodiments, the transmission pattern of the synchronization signal blocks is a second pattern, M synchronization signal blocks are included in one SS Burst Set, M is a positive integer less than or equal to 4, and the method 100 further includes: and determining the candidate position of the third time slot as the first time slot and the third time slot in the sending time window of the synchronous signal block. Optionally, in a case where the network device and the terminal device communicate via a carrier less than 3GHz, the number of synchronization signal blocks in one SS Burst Set is less than or equal to 4.

That is, if the transmission pattern of the synchronization signal block is the second pattern, when M synchronization signal blocks need to be transmitted, M slots can be selected from candidate positions of the third slot in the transmission time window of the synchronization signal block for transmitting the M synchronization signal blocks. For example, when 1 or 2 synchronization signal blocks need to be transmitted, the synchronization signal block may be transmitted on the first slot in the transmission time window of the synchronization signal block, or the synchronization signal block may be transmitted on the third slot in the transmission time window of the synchronization signal block. When 3 synchronization signal blocks need to be transmitted, the first and second synchronization signal blocks may be transmitted on the first slot of the transmission time window, and the third synchronization signal block may be transmitted on the third slot of the transmission time window, or the first synchronization signal block may be transmitted on the first slot of the transmission time window, and the second and third synchronization signal blocks may be transmitted on the third slot. When 4 synchronization signal blocks need to be transmitted, the first and second synchronization signal blocks may be transmitted on the first slot of the transmission time window, and the third and fourth synchronization signal blocks may be transmitted on the third slot of the transmission time window.

For example, fig. 7 shows that when the transmission pattern of the SSB is the second pattern shown in fig. 6 and 4 SSBs are included in one SS Burst Set, the slots for transmitting the SSB are the first and third slots (slots filled with oblique lines in fig. 7) in the transmission time window with the length of 5 ms.

Specifically, in other embodiments, the transmission pattern of the synchronization signal blocks is a second pattern, an SS Burst Set includes N synchronization signal blocks, N is a positive integer less than or equal to 8, and the method 100 further includes: and determining candidate positions of the third time slot as the first time slot, the third time slot, the fifth time slot and the seventh time slot in the sending time window of the synchronous signal block. Optionally, when the frequency of the carrier used in the communication between the network device and the terminal device is between 3GHz and 6GHz, the number of the synchronization signal blocks included in one SS Burst Set is less than or equal to 8.

It should be noted that, when the transmission pattern of the synchronization signal block is the second pattern, when one SS Burst Set includes N synchronization signal blocks, the manner of determining the candidate positions for transmitting the synchronization signal blocks is similar to the manner of determining the candidate positions for transmitting the synchronization signal blocks when one SS Burst Set includes M synchronization signal blocks described above, and details are not repeated here.

For example, fig. 8 shows that when the transmission pattern of the SSB is the second pattern shown in fig. 6 and 8 SSBs are included in one SS Burst Set, the slots for transmitting the SSBs are the first, third, fifth and seventh slots (slots filled with oblique lines in fig. 8) in the transmission time window with the length of 5 ms.

In this embodiment of the present application, optionally, it may be preset that a parameter set whose corresponding subcarrier interval is 60kHz cannot be used in an initial access process, and when the method 100 is applied to the initial access process, when a frequency point of transmitting a synchronization signal block is lower than 6GHz, it is determined that the subcarrier interval corresponding to a first parameter set is 15kHz or 30kHz, and when a frequency point of transmitting other signals is lower than 6GHz, it is determined that the subcarrier interval corresponding to a second parameter set is 15kHz or 30 kHz.

Correspondingly, the terminal device detects the SSB in the frequency band below 6GHz during the initial access, and considers that the second parameter set of other signals transmitted in a multiplexing manner with the SSB cannot be 60 kHz. It will be appreciated that the second set of parameters for the other signal refers to the set of parameters used by the network device when transmitting the other signal.

In this embodiment, optionally, the first parameter set, the second parameter set, and the correspondence relationship between the transmission Pattern of the synchronization signal block and the frequency band used for transmitting the synchronization signal block may be preset, for example, when the subcarrier interval corresponding to the first parameter set is defined as 30kHz, the subcarrier interval corresponding to the second parameter set is defined as 15kHz, and the transmission Pattern of the synchronization signal block is Pattern1 in the foregoing, the synchronization signal block and other signals are transmitted in some frequency bands below 6 GHz. Or when the subcarrier interval corresponding to the first parameter set is defined to be 30kHz, the subcarrier interval corresponding to the second parameter set is defined to be 60kHz, and the transmission pattern of the synchronous signal block is the second pattern in the above, the synchronous signal block and other signals are transmitted on other frequency bands below 6 GHz. And in this case, the network device may indicate the transmission pattern of the synchronization signal block through the indication information, in a manner to be described in detail below.

Specifically, in some embodiments, when it is determined that the subcarrier interval corresponding to the first parameter set is 30kHz, the subcarrier interval corresponding to the second parameter set is 15kHz, and the frequency domain position occupied by the synchronization signal block is within the first frequency band, the network device determines that the transmission pattern of the synchronization signal block is a third pattern, in the third pattern, the candidate positions of the time domain position occupied by the synchronization signal block are the 5 th to 8 th symbols and the 9 th to 12 th symbols of the fourth time slot corresponding to the first parameter set, and the 3rd to 6 th symbols and the 7 th to 10 th symbols of the fifth time slot corresponding to the first parameter set, the fourth time slot and the fifth time slot are adjacent time slots, and the frequency point of the subcarrier within the first frequency band is lower than 6 GHz. It should be noted that the third Pattern here may correspond to Pattern1 above.

Specifically, in other embodiments, when it is determined that the subcarrier interval corresponding to the first parameter set is 30kHz, the subcarrier interval corresponding to the second parameter set is 60kHz, and the frequency domain position occupied by the synchronization signal block is within the second frequency band, the network device determines that the transmission pattern of the synchronization signal block is a fourth pattern, in the fourth pattern, the candidate positions of the time domain position occupied by the synchronization signal block are the 3rd to 6 th symbols and the 9 th to 12 th symbols of the sixth time slot corresponding to the first parameter set, and the frequency point of the subcarrier within the second frequency band is lower than 6 GHz. It should be noted that the fourth pattern herein may correspond to the second pattern above.

It can be understood that, if the first parameter set, the second parameter set and the corresponding relationship between the transmission pattern of the synchronization signal block and the frequency band used for transmitting the synchronization signal block are preset, when the network device transmits the synchronization signal block, the frequency band used for transmitting the synchronization signal block may be determined according to the first parameter set, the second parameter set and the transmission pattern of the synchronization signal.

Specifically, in some embodiments, if the network device determines that the subcarrier spacing corresponding to the first parameter set is 30kHz, the subcarrier spacing corresponding to the second parameter set is 15kHz, and the transmission pattern of the synchronization signal block is the third pattern, it determines that the frequency domain position occupied by the synchronization signal block is within the first frequency band.

Specifically, in other embodiments, if the network device determines that the subcarrier interval corresponding to the first parameter set is 30kHz, the subcarrier interval corresponding to the second parameter set is 60kHz, and the transmission pattern of the synchronization signal block is a fourth pattern, it determines that the frequency domain position occupied by the synchronization signal block is within the second frequency band.

In this embodiment of the present application, optionally, the network device sends first indication information to the terminal device, where the first indication information is used to indicate a transmission pattern of the synchronization signal block. Therefore, the complexity of blind detection of the terminal equipment can be reduced.

Optionally, in an embodiment, a network device sends a master information block MIB to a terminal device, where the MIB carries the first indication information. For example, when the network device communicates with the terminal device at a frequency of less than 6GHz, 1bit or more bits in the MIB may be used to carry the first indication information. Or the network equipment carries the first indication information by using 1bit or more bits in the MIB no matter the network equipment communicates with the terminal equipment below 6GHz or above 6 GHz. For example, when the value of the first indication information is 1, the transmission Pattern indicating the SSB is Pattern1 described above.

Optionally, in some embodiments, the first indication information is carried in floating synchronization (floating sync) information in the MIB.

Optionally, in some embodiments, the other signal includes Remaining Minimum System Information (RMSI) and a RMSI Control Resource Set (core), and the MIB further includes RMSI core configuration information and second indication information, where the second indication information is used for the terminal device second parameter Set. It will be appreciated that in this case the second parameter set is actually the parameter set used by the network device to transmit the RMSI and the RMSI core set.

Optionally, in some embodiments, the second indication information directly indicates the second parameter set. Alternatively, the second indication information is used to indicate whether the second parameter set is identical to the first parameter set. The terminal equipment determines a second parameter set according to the first parameter set and the second indication information. Or further, the terminal device determines a second parameter set according to the first parameter set and the second indication information, and determines a specific time-frequency domain position of the RMSI core according to the first parameter set, the second parameter set and the RMSI core configuration information. Or the terminal equipment determines the second parameter set according to the first parameter set, the transmission pattern indicated by the first indication information and the second indication information. Therefore, the blind detection frequency of the terminal equipment can be further reduced. Or further, the terminal device determines a second parameter set according to the first parameter set, the transmission pattern indicated by the first indication information and the second indication information, and determines a specific time-frequency domain position of the RMSI core according to the first parameter set, the transmission pattern indicated by the first indication information, the second parameter set and the RMSI core configuration information.

For example, the network device and the terminal device may agree in advance with the correspondence relationship shown in table 1, and as an example, if the terminal device determines that the subcarrier interval (subcarrier interval used by the transmission SSB) corresponding to the first parameter set is 120kHz, and the second indication information is only 1bit and indicates that the second parameter set is different from the first parameter set (for example, if the value is 0, it indicates that the second parameter set is different from the first parameter set), the terminal device may determine that the subcarrier interval corresponding to the second parameter set of the network device is 60kHz according to the correspondence relationship in table 1. Or further, based on the description of the foregoing embodiment, as another example, assuming that the terminal device determines that the subcarrier spacing (subcarrier spacing used by the transmission SSB) corresponding to the first parameter set is 120kHz and the subcarrier spacing (subcarrier spacing used by the transmission SSB) corresponding to the first parameter set is 60kHz, the end device may determine the time-frequency domain position of the RMSI CORESET according to the first parameter set (120kHz), the second parameter set (60kHz) and the RMSI CORESET configuration information (e.g., "110") carried by the MIB.

Or, as another example, if the terminal device determines that the subcarrier interval (the subcarrier interval used by the transmission SSB) corresponding to the first parameter set is 30kHz, determines that the transmission Pattern of the synchronization signal block is Pattern1, and determines that the second indication information is only 1bit and indicates that the second parameter set is different from the first parameter set (for example, if the value is 0, it indicates that the second parameter set is different from the first parameter set), the terminal device may determine that the subcarrier interval corresponding to the second parameter set of the network device is 15kHz according to the correspondence in table 1. It should be noted that, the corresponding relationship in the table may also be that the network device notifies the terminal device through a signaling, the Pattern2 in table 1 corresponds to the second Pattern in the foregoing, the use of the second indication information in table 1 for the 1-bit bearer is only an example, and the value of the 1bit being 0 or 1 is also only an example, and does not limit the scope of the embodiment of the present application.

TABLE 1

Or further, based on the description of the foregoing embodiment, as another example, assuming that the terminal device determines that the subcarrier interval (subcarrier interval used by the transmission SSB) corresponding to the first parameter set is 30kHz, determines that the transmission Pattern of the synchronization signal block is Pattern1, and determines that the subcarrier interval corresponding to the second parameter set is 15kHz, the terminal device may determine the time-frequency domain position of the RMSI CORESET according to the first parameter set (30kHz), the second parameter set (15kHz), the Pattern information (Pattern1) indicated by the first indication information, and the RMSI CORESET configuration information (e.g., "110") carried by the MIB.

Optionally, in some embodiments, a sequence and/or a scrambling manner of a synchronization Signal and/or a demodulation Reference Signal DMRS (De Modulation Reference Signal) carried in the synchronization Signal block has a corresponding relationship with a transmission pattern of the synchronization Signal block. It should be noted that the correspondence relationship herein may include a direct correspondence relationship and may include an indirect correspondence relationship. The direct correspondence relationship refers to that the sequence and/or scrambling method of one kind of synchronization signal and/or DMRS directly corresponds to the transmission pattern of one kind of synchronization signal block. The indirect corresponding relation refers to that a sequence and/or a scrambling mode of a synchronization signal and/or a DMRS directly correspond to a value of a bit carrying the first indication information, and the value of the bit carrying the first indication information has a direct corresponding relation with a transmission pattern of a synchronization signal block.

In this embodiment, it may be optionally defined that the subcarrier interval corresponding to the first parameter set is 30kHz, the subcarrier interval corresponding to the second parameter set is 60kHz or 15kHz, and when the transmission Pattern of the synchronization signal block is Pattern1 in the foregoing or the second Pattern in the foregoing, the transmission type of the time slot in which the symbol for transmitting the other signal is located is. And in this case a parameter set that may define a subcarrier spacing of 60kHz cannot be used for the initial access procedure.

It should be noted that the fifth Pattern corresponds to Pattern1 above, and the 7 th symbol in the seventh time slot and the eighth time slot is actually the 12 th symbol and the 13 th symbol corresponding to the second parameter set.

For example, as shown in fig. 9, the subcarrier spacing corresponding to the first parameter set is 30kHz, the subcarrier spacing corresponding to the second parameter set is 60kHz, and the transmission Pattern of the SSB is Pattern1, then the symbol 6 in the first time slot corresponding to 30kHz in fig. 9 is only transmitted downstream, that is, the symbol 12 and the symbol 13 in the first time slot corresponding to 60kHz in fig. 9, and the symbol 12 and the symbol 13 in the third time slot are only transmitted downstream.

It should be noted that the sixth pattern here may correspond to the second pattern and the fourth pattern in the foregoing, and the 13 th symbol and the 14 th symbol in the ninth slot are actually the 14 th symbol corresponding to the second parameter set.

For example, as shown in fig. 10, the subcarrier spacing corresponding to the first parameter set is 30kHz, the subcarrier spacing corresponding to the second parameter set is 15kHz, and the transmission pattern of the SSB is the sixth pattern, then the symbol 12 and the symbol 13 in the second slot corresponding to 30kHz in fig. 10 are transmitted only downstream, i.e., the symbol 13 corresponding to 15kHz in fig. 10.
