Description

Method for transmitting synchronization signal block, terminal equipment and network equipment Technical Field

The present application relates to the field of communications, and in particular, to a method, a terminal device, and a network device for transmitting a synchronization signal block.

Background

In New Radio (NR), a position (position) index (index) of a Synchronization Signal (SSB)/Physical Broadcast Channel (PBCH) block (block) (hereinafter referred to as "SSB") may be used to obtain a Synchronization and Quasi-Co-located (QCL) relationship. Specifically, the QCL relationship of the SSBs is obtained by determining a Mod (SSB position index, Q) whose SSBs have the same QCL relationship as a result, or calculating a Mod (PBCH DMRS sequence index, Q) whose SSBs have the same QCL relationship as a result of calculating the PBCH DMRS sequence index (sequence) index from the lowest three bits of the SSB position index, i.e., the PBCH Demodulation Reference Signal (DMRS) sequence (sequence) index. The parameter Q is generally defined as the maximum number of beams or the maximum number of SSBs having no QCL relationship within a Discovery Reference Signal (DRS) window.

Currently, within the DRS transmission window, the transmission granularity of the SSBs may be half a slot or one slot, that is, each slot may transmit two SSBs or only one SSB, or the minimum interval between adjacent SSBs is 1 or 2 candidate locations. For the case that two SSBs can be transmitted in each timeslot, that is, the minimum interval between adjacent SSBs is 1 candidate location, if the SSBs of different beams obtain the same value in the above manner, the SSBs of the different beams have a QCL relationship; if different values are obtained, there is no QCL relationship between the SSBs of the different beams. However, for the case where only one SSB can be transmitted per timeslot, that is, the minimum interval between adjacent SSBs is 2 candidate locations, the SSBs of different beams still have no QCL relationship if they obtain the same value by the above-mentioned method, and therefore, the method for determining the QCL relationship between the SSBs in the prior art may obtain an incorrect QCL relationship in such a case.

In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

Several concepts involved in the embodiments of the present application are described in detail below.

One, NR-U system

Unlicensed spectrum is a nationally and regionally divided spectrum that may be used for communication by radio devices, and is generally considered a shared spectrum, i.e., a spectrum that may be used by communication devices in different communication systems as long as the regulatory requirements set by the country or region on the spectrum are met, without requiring a proprietary spectrum license to be applied to the government. In order for various communication systems using unlicensed spectrum for wireless communication to coexist friendly on the spectrum, some countries or regions stipulate regulatory requirements that must be met using unlicensed spectrum. For example, in european regions, a communication device follows the principle of "listen-before-talk (LBT)", that is, before performing signal transmission on a channel of an unlicensed spectrum, the communication device needs to perform channel sensing first, and only when a channel sensing result is that the channel is idle, the communication device can perform signal transmission; if the channel sensing result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot transmit signals. In order to ensure fairness, in one transmission, the duration of signal transmission by the communication device using the unlicensed spectrum Channel cannot exceed the Maximum Channel Occupancy Time (MCOT).

Second, SS/PBCH block in NR system

Common channels and signals in the NR system, such as synchronization signals and broadcast channels, need to cover the whole cell in a multi-beam scanning manner for UEs in the cell to receive. Multi-beam transmission of synchronization signals is achieved by defining a set of SS/PBCH pulses (burst set). An SS burst set contains one or more SS/PBCH blocks. One SS/PBCH block is used to carry the synchronization signal and broadcast channel of one beam. Thus, one SS/PBCH burst set may contain synchronization signals for the number (number) of SS/PBCH block beams within a cell. The maximum number of SS/PBCH block numbers may be denoted as L, which is related to the frequency band of the system, e.g., the frequency range is less than or equal to 3GHz, L is 4; the frequency range is 3GHz to 6GHz, and L is 8; the frequency range is 6GHz to 52.6GHz, and L is 64.

Fig. 2 shows a schematic diagram of time-frequency resources occupied by one SS/PBCH block (hereinafter referred to as "SSB"). As shown in fig. 2, an SSB may include a Primary Synchronization Signal (PSS) of an Orthogonal Frequency Division Multiplexing (OFDM) symbol, a Secondary Synchronization Signal (SSS) of an OFDM symbol, and an NR-PBCH of two OFDM symbols, where a time-Frequency resource occupied by the PBCH may include a Demodulation Reference Signal (DMRS) used for Demodulation of the PBCH.

All SSBs in the SS/PBCH burst set are usually transmitted in a time window of 5ms, and are repeatedly transmitted with a certain period, which may be configured by parameter SSB time (SSB-timing) information of a higher layer, for example, the period may include 5ms, 10ms, 20ms, 40ms, 80ms, 160ms, and so on. For the UE, the index (index) of the SSB is obtained through the received SSB, where the SSB index corresponds to the relative position of the SSB within the 5ms time window, and the UE obtains frame synchronization according to the information and the half-frame indication information carried in the PBCH. Wherein, the index of the SSB may be indicated by DMRS of PBCH or information carried by PBCH.

Fig. 3 shows a slot distribution pattern of SSBs at different subcarrier spacing (SCS) according to an embodiment of the present application. Taking a 15kHz subcarrier spacing, L ═ 4 as an example, one slot (slot) contains 14 symbols (symbols), and can carry two SSBs altogether, with 4 SSBs being distributed in the first two slots within a 5ms time window.

It should be understood that the number L of SSBs in the embodiment of the present application is the largest number of SSBs, that is, the number of SSBs actually sent may be less than or equal to L. The position of the SSB actually transmitted may be notified to the terminal through system information in the form of a bitmap (bitmap). The number and location of the SSBs actually transmitted are determined by the base station. In the NR system, since L is the maximum number of SSBs transmitted in a certain frequency band, the value range of the SSB index is [0, L-1 ]. For example, in a frequency band below 6GHz of the licensed spectrum, there are at most 8 SSBs included in the SSB burst, and the value range of the SSB index is 0 to 7.

In NR systems using licensed spectrum, SSB index may be used for UEs to obtain frame synchronization and QCL relationships. The former obtains the position of the SSB in the radio frame through the SSB index and the field indication, thereby obtaining frame synchronization. The latter UE assumes that SSBs of the same SSB index have a QCL relationship, i.e., if the indices of SSBs received at different times are the same, the UEs are considered to have a QCL relationship therebetween. When two reference signals (e.g., SSBs) have a QCL relationship, the large-scale parameters of the two reference signals can be considered to be mutually inferred, or can be considered to be similar, wherein the large-scale parameters can include, for example, doppler delay, average delay, spatial reception parameters, and the like. The UE may filter the SSBs with QCL relationship during measurement as the measurement result of the beam level.

DRS in NR-U system

In the NR-U system, for one Primary Cell (Pcell), a network device transmits a DRS signal, which may include at least an SSB, for access, measurement, and the like. In consideration of the uncertainty of obtaining the channel usage right in the unlicensed spectrum, the network device may not successfully transmit the SSB at a predetermined time in the transmission process of the SSB due to the possibility of LBT failure. Therefore, the problem can be solved by increasing the transmission opportunity of the SSB. Specifically, in a DRS transmission window, the number Y of candidate locations of SSBs configured by the network device is greater than the number X of SSBs actually sent by the network device. That is, for each DRS transmission window, the network device may determine to transmit a DRS using X available candidate locations of the Y candidate locations according to the detection of LBT within the DRS transmission window.

For example, in a time window of up to 5ms, 20 candidate positions are defined for SSB with a subcarrier spacing of 30kHz and 10 candidate positions are defined for SSB with a subcarrier spacing of 15 kHz. Assuming that the maximum number of the transmitted SSBs is Q, the base station determines to transmit the DRS using the maximum Q candidate locations of the multiple candidate locations according to the detection result of the LBT within the DRS transmission window. The parameter Q may be configured by a network device for a terminal device, or may also be specified by a protocol, and the embodiment of the present application is not limited thereto.

Fig. 4 shows a schematic diagram of LBT at candidate locations. As shown in fig. 4, the maximum number Q of the transmitted SSBs is 4, and correspondingly, the possible starting positions of the 4 SSBs may be any one of the 20 candidate positions in fig. 4, taking the subcarrier spacing as 30kHz and defining 20 candidate positions as an example for explanation. It is assumed here that the base station performs LBT only at candidate position indexes 0, 4, 8, 12 and 16 as shown in fig. 4, that is, the four positions are taken as possible starting positions of 4 SSBs. As shown in fig. 4, assuming that LBT performed by the base station before the candidate location 12 is successful, the corresponding transmission of the SSB QCL index 0-3 is started.

For the transmission mode of the SSB defined in the NR-U, since the UE needs to obtain frame synchronization by the SSB received at the candidate transmission position, an SSB position (position) index needs to be defined for the candidate transmission position. For example, taking Q-4 and Y-20 as shown in fig. 4 as an example, since a maximum of 4 SSBs may be sent at 20 candidate positions, the position index carried by the SSB needs to be extended to 0 to Y-1, i.e., the SSB position index carried by the SSB needs to be extended to 0 to 19, so that the UE obtains the position of the received SSB to further obtain frame synchronization.

Since the maximum number of SSBs transmitted is 4, the value range of the SSB QCL index used for obtaining the QCL relationship between the SSBs is 0 to 3, that is, the value range of the SSB position index is different from the value range of the SSB QCL index, but the UE can determine the QCL relationship information of the SSBs through the received SSB position index obtained by the SSBs. For SSBs sent at different time, if the SSB QCL indexes are the same, the SSBs are considered to have a QCL relationship. In other words, no QCL relationship exists between SSBs with different SSBs QCL indexes.

The QCL information of the SSB may be obtained by calculating an SSB QCL index (Q) that has the same QCL relationship as the SSB QCL index; alternatively, it may be simplified that the SSBs with the same result determined by the lowest three bits in the bitmap for indicating the SSB position index, that is, by the PBCH DMRS sequence (sequence) index, that is, the SSB QCL index Mod (PBCH DMRS sequence index, Q), have the QCL relationship.

FIG. 5 illustrates the quasi co-location relationship of SSBs with different position indices. As shown in fig. 5, assuming that there are 32 candidate positions for transmitting SSBs, the position index ranges from 0 to 31, and the maximum number of SSBs transmitted is 8, that is, the SSBs QCL index for obtaining the QCL relationship between the SSBs ranges from 0 to 7, then there may be a plurality of SSBs with different position indexes but having QCL relationships. For example, as shown in fig. 5, four SSBs having SSB position indexes of 0,8,16, and 24 each have a QCL relationship.

In this case, the SSB of any beam is located at any position of the Y candidate transmission positions, that is, the SSB position index of the SSB; in addition, the parameter Q for determining the QCL information of the SSB may be carried by PBCH, may be carried by system message, and may be predefined. After the UE receives the SSB, the QCL information of the SSB may be obtained according to the received parameter Q and the SSB position index. SSBs with QCL relationships can be jointly processed to improve performance.

According to the above method, the QCL information of the SSBs is obtained by determining whether different SSBs have a QCL relationship according to whether the results of Mod (SSB position index, Q) are the same or according to whether the results of the lowest three bits of the SSB position index, for example, Mod (PBCH DMRS sequence index, Q) are the same. The parameter Q is generally defined as the maximum number of beams equal to the terminal device, or the maximum number of SSBs having no QCL relationship within the DRS window.

Currently, within the DRS transmission window, the transmission granularity of SSBs may be generally half a slot or one slot, that is, two SSBs or only one SSB may be transmitted in each slot, or the minimum separation of adjacent SSBs is 1 or 2 candidate locations. Fig. 6 shows a schematic diagram OF different transmission granularities OF SSBs, and as shown in fig. 6, it is assumed that a parameter Q is 4, that is, SSBs transmitting 4 beams in total, and OF is 2 and OF is 1 indicate that the minimum interval OF adjacent SSBs is 2 and 1 candidate positions, respectively.

In the case OF being 1, that is, the minimum interval between the positions OF adjacent SSBs is 1, that is, two SSBs can be transmitted per slot, in this case, when the SSBs OF different beams are calculated in the above manner to obtain different SSB QCL indexes, it indicates that there is no QCL relationship between the SSBs OF the different beams, and conversely, when the SSBs OF different beams are calculated to obtain the same SSB QCL index, it indicates that there is a QCL relationship between the SSBs OF the different beams.

However, in the case OF 2, that is, the minimum interval between the positions OF the adjacent SSBs is 2, that is, only one SSB can be transmitted per slot, and in this case, if the calculation is still performed in the above manner, as shown in fig. 6, the SSB OF beam 0 and the SSB OF beam 2 have the same corresponding determined SSB QCL index result, and they should have a QCL relationship, while in reality, the SSB OF beam 0 and the SSB OF beam 2 are different beams and have no QCL relationship. Therefore, the method of determining the QCL relationship between SSBs in the above manner may result in an incorrect QCL relationship between SSBs in such a case.

Therefore, the embodiments of the present application provide a method for transmitting a synchronization signal block, which can solve the above problems and accurately determine whether SSBs at different positions have a quasi-co-location relationship.

Fig. 7 is a schematic flow chart of a method 200 for transmitting a synchronization signal block according to an embodiment of the present application. As shown in fig. 2, the method 200 includes:

s210, determining quasi-co-location information of the first SSB according to the position index of the first SSB, the SSB numerical parameter and the SSB interval parameter, wherein the SSB interval parameter is used for indicating the minimum interval between the positions of two adjacent SSBs in a transmission window in the time domain.

It should be understood that the method 200 may be performed by a terminal device, which may be the terminal device shown in fig. 1, or by a network device, which may be the network device shown in fig. 1, for example. For convenience of description, the terminal device executes the method 200 as an example, and correspondingly, the network device may also execute the method 200 in the same manner, and the embodiment of the present application is not limited thereto.

It should be understood that the first SSB in the embodiments of the present application may refer to any SSB, and the terminal device or the network device may determine QCL information of one or more SSBs according to the method 200. Alternatively, if the QCL information of the SSBs is the same, for example, the terminal device determines that the QCL index of the first SSB is the same as the QCL index of the second SSB according to the method 200, the first SSB and the second SSB may be considered to have a QCL relationship.

It should be understood that the method 200 in the embodiment of the present application may further include: location information for the first SSB is determined. Specifically, the terminal device may determine the location information of the first SSB in various ways, where the location information of the first SSB may include a location index of the first SSB, and for example, the location index may represent a number of possible transmission locations of the first SSB.

Alternatively, the terminal device may determine the location index of the first SSB by detecting the first SSB, for example, the terminal device detects the first SSB and generates a detection result; and the terminal equipment determines the position index of the first SSB according to the detection result. Wherein, the position index of the first SSB represents the time domain position of the first SSB received by the terminal device.

Alternatively, the terminal device may also obtain the location index of the first SSB in other manners, for example, the terminal device may receive the location index of the first SSB sent by the network device. For example, the terminal device may receive a PBCH sent by the network device, where the PBCH includes a location index of the first SSB.

It should be understood that the range of the position index of the first SSB in the embodiment of the present application indicates a possible transmission position of the first SSB. For example, the position index of the first SSB may have a value range related to a transmission window size, for example, the transmission window may refer to a transmission window of a DRS, that is, the position index of the first SSB has a value range determined by the transmission window size of a DRS, or the position index of the first SSB has a value range corresponding to the transmission window size of a DRS, where the DRS includes the first SSB; and/or the value range of the position index of the first SSB may also be related to the subcarrier spacing, that is, the value range of the position index of the first SSB may also be determined by the subcarrier spacing, or the value range of the position index of the first SSB and the subcarrier spacing have a corresponding relationship.

For example, when the transmission window sizes are different, the number of possible transmission positions of the SSBs may be the same or different, that is, the value ranges of the position indexes of the first SSB may be the same or different; on the contrary, in the case that the transmission windows have the same size, when the subcarrier intervals are different, the number of the possible transmission positions of the SSB may still be the same or different, that is, the value range of the position index of the first SSB may be the same or different, and the embodiment of the present application is not limited thereto.

For example, taking fig. 4 as an example, if the DRS window size is 5ms, the subcarrier spacing of the SSBs is 30kHz, the number of possible transmission positions of the SSBs is 20, that is, the position index of the first SSB has a value ranging from 0 to 19. For another example, if the DRS window size is 5ms, and the subcarrier spacing of the SSB is 15kHz, 10 candidate positions are defined, that is, the number of possible transmission positions of the SSB is 10, that is, the position index of the first SSB has a value range of 0 to 9.

It should be understood that, for a network device, the network device may adopt LBT to select one or more of the 20 or 10 possible transmission positions, for example, to transmit an SSB, and the position index of the first SSB may indicate an index of a position where the first SSB is actually transmitted, so that a terminal device may determine the position index of the first SSB and may also receive the first SSB.

It should be understood that the method 200 in the embodiment of the present application may further include: SSB numerical parameters are determined. Specifically, the terminal device may determine the SSB numerical parameter in various ways, for example, the terminal device may receive the SSB numerical parameter sent by the network device; or, the terminal device may autonomously determine the SSB numerical parameter; alternatively, the SSB value parameter may also be predefined, e.g., may be protocol-specified; alternatively, the SSB numerical parameter may be determined jointly in a plurality of ways, for example, jointly according to predefined parameters and parameters sent by the network device, and the embodiments of the present application are not limited thereto.

For the case that the terminal device receives the SSB value parameter sent by the network device, the method may include: the terminal device receives an indication message sent by a network device, where the indication message is used to indicate the SSB numerical parameter, where the indication message may be: system message, PBCH, or Radio Resource Control (RRC) signaling, but the embodiments of the present application are not limited thereto.

It should be understood that the SSB value parameter may be any value, i.e., the SSB value parameter may have no specific meaning, e.g., the SSB value parameter may be a value configured by a network device, which may be equal to any number. Alternatively, the SSB numerical parameter may be at least one of the following: the SSB numerical parameter may be a maximum number of beams of the SSB; the SSB numerical parameter is the maximum number of SSBs in a transmission window; the SSB value parameter may also be a maximum number of SSBs that do not have a QCL relationship within a transmission window. Herein, a transmission window may refer to a transmission window of one DRS, but the embodiment of the present application is not limited thereto.

It should be understood that the method 200 in the embodiment of the present application may further include: and determining an SSB interval parameter which is the minimum interval between the positions of two adjacent SSBs in the time domain in one transmission window. Specifically, the SSB interval parameter may represent the transmission granularity of the SSBs in the time domain, that is, the minimum interval of the adjacent SSBs within one transmission window, and may be determined, for example, by calculating the difference between the position indexes of the two adjacent SSBs, where the SSB interval parameter is equal to the minimum value of the difference between the position indexes of the two adjacent SSBs; alternatively, the SSB interval parameter may indicate that the SSB is transmitted in several slots, for example, the SSB may be transmitted in a half slot or a minimum interval of one slot.

It should be understood that a transmission window in the embodiments of the present application may refer to a transmission window of any size, for example, the transmission window may refer to a transmission window of one DRS. For convenience of illustration, a DRS transmission window is described below as an example.

For example, as shown in fig. 6, assuming that a timeslot has two candidate transmission positions OF SSBs, the SSB interval parameter OF may be set to 1, which indicates that the minimum interval OF adjacent SSBs is a candidate position OF an SSB, that is, a timeslot can transmit two SSBs at most; alternatively, the SSB interval parameter OF may be set to 2, which indicates that the minimum interval between adjacent SSBs is a candidate position OF two SSBs, that is, at most one SSB may be sent in one timeslot, and so on.

It should be understood that the SSB interval parameter may be determined by the terminal device in various ways, for example, the terminal device may receive the SSB interval parameter sent by the network device; or, the terminal device may determine the SSB interval parameter by itself; alternatively, the SSB interval parameter may also be predefined, e.g., may be protocol-specified; alternatively, the terminal device may also determine the SSB interval parameter jointly in a plurality of manners, for example, the terminal device jointly determines the SSB interval parameter in combination with predefined information and information sent by the network device, and the embodiment of the present application is not limited thereto.

Optionally, for a case that the terminal device receives the SSB interval parameter sent by the network device, the method may specifically include: the terminal device receives an indication message sent by the network device, where the indication message is used to indicate the SSB interval parameter, and the indication message may be: system messages, PBCH, or RRC signaling.

Optionally, for a case where the SSB interval parameter is carried by a System message, the SSB interval parameter may be carried by a System Information Block (SIB) 1 in the System message, or carried by another System message.

Alternatively, for the case of carrying the SSB interval parameter by PBCH, the SSB interval parameter may be indicated by a Master Information Block (MIB) carried in PBCH and/or information bits other than MIB.

For example, the information carried by the PBCH channel may include a-bit information from a higher layer and additional 8-bit information related to layer 1, and the information related to layer 1 includes a System Frame Number (SFN), a half Frame indication, an SSB index, and the like.

In particular, the bits carried by the PBCH include the a-bit MIB from the higher layer, i.e.

Also including 8 bits from layer 1, i.e.

Wherein the definition of the A bit MIB comprises at least one of the following: the data transmission method comprises the following steps of 6 bits of SFN, 1 bit of subcarrier interval information, 4 bits of subcarrier offset of SSB, DMRS related information, resource information of PDCCH of a scheduling SIB, and 1 idle bit.

It should be understood that the sub-carrier offset (SSB-subcarrier offset) information field of the SSB includes 4 bits for indicating an offset k between Physical Resource Block (PRB) grids between channels or signals of a sync signal Block and a non-sync signal Block_SSBThe offset comprising 0-11 or 0-23 sub-carriers, the ssb-SubcarrierOffset information field corresponding to the parameter k_SSBThe lowest 4 bits. The subcarrier spacing information field is subcarriersspacingcommon, which may be used to indicate: the network sends SIB1, Msg.2/4 for initial access, and the subcarrier spacing used when paging and broadcast (paging and broadcast) SI-messages.

8 bits of layer 1

In (1),

the lowest 4 bits of SFN;

indicated for a field; when L is_SSBWhen the number is 64, the number is as follows,

the highest 3 bits of the SSB index, otherwise,

is a parameter k_SSBThe highest order bit of the group of bits,

to reserve bits. Wherein L is_SSBIs the maximum number of SSBs, k_SSBIs subcarrier offset information of the SSB. When the system band is less than 6GHz, i.e. L_SSBLess than 64, there are 2 reserved bits for layer 1 related information.

When the SSB interval parameter is carried by the MIB, all or part of bits in a subcarrier interval information field (subcarrierspaceingcommon) in the MIB, a subcarrier offset information field (SSB-subcarriersoffset) of the SSB, and a resource information field (PDCCH-ConfigSIB1) of a PDCCH of the scheduling SIB1 may be reused; when the SSB interval parameter is indicated by information bits other than the MIB, all or part of bits among the most significant bits, reserved bits, field indication bits, and the like in the SSB-subarrieraffset information field may be passed. When the interval parameter of the SSB is carried in the PBCH, the MIB and information bits other than the MIB may also be used together for indication. In addition, the SSB interval parameter and the SSB value parameter may also be jointly encoded and indicated in several ways as described above.

Optionally, when measuring the SSB of the neighboring cell, the SSB interval parameter may also be carried through RRC signaling, for example, the SSB interval parameter is indicated in the measured configuration information, for example, MeasConfig, MeasObject, and the like.

It should be understood that, in the embodiment of the present application, the QCL information of the first SSB may include a QCL index of the first SSB, and correspondingly, S210 in the method 200 may specifically include: the QCL index for the first SSB may be determined based on the location index, the SSB value parameter, and the SSB interval parameter for the first SSB. For example, the result of the position index of the first SSB modulo the product of the SSB value parameter and the SSB interval parameter is determined as the quasi-co-located index of the first SSB.

Alternatively, the QCL index of the first SSB may be determined by the following equation (1):

QCL＝mod(P，Q*OF) (1)

wherein QCL is the quasi-co-located index OF the first SSB, P is the location index OF the first SSB, Q is the numerical parameter, and OF is the SSB interval parameter.

According to the formula (1), when the SSB interval parameter and the numerical parameter take values respectively, the QCL index of the first SSB corresponding to the arbitrary position index can be determined. For example, fig. 8 shows a schematic diagram of the location and QCL relationship of different SSBs with an SSB interval parameter of 2. As shown in fig. 8, it is assumed that there are 20 candidate positions of the SSB within the transmission window of one DES, i.e., the possible value range of the position index of the SSB is 0-19, but fig. 8 only shows the positions 0-15; it is also assumed here that the SSB interval parameter OF is 2, that is, the minimum interval between the positions OF any two adjacent SSBs sent by the network device is 2, that is, only one SSB can be transmitted in one timeslot, for example, the SSB in fig. 8 can only be transmitted through the position OF the black square, and is not located at the position OF the dashed box; in addition, it is assumed here that the numerical parameter Q is equal to 4. Therefore, as can be seen from the calculation result OF equation (1), when the SSB interval parameter OF is 2, if the calculation results OF the plurality OF SSBs are the same, it can be determined that the plurality OF SSBs have the QCL relationship, and conversely, the plurality OF SSBs do not have the QCL relationship. For example, two SSBs with SSBs location indices of 0 and 8 result the same and thus have a QCL relationship, while two SSBs with SSBs location indices of 0 and 4 result differently and thus do not have a QCL relationship. In comparison with the case of calculating the QCL relationship using Mod (SSB position index, Q), the results of calculating two SSBs having SSBs with position indices of 0 and 4 are the same, but actually, they have no QCL relationship, and therefore, the calculation is erroneous.

As another example, fig. 9 shows a schematic diagram of the location and QCL relationship of different SSBs when the SSB interval parameter is 1. As shown in fig. 9, similar to fig. 8, it is assumed that there are 20 candidate positions of the SSB within the transmission window of one DES, i.e., the possible value range of the position index of the SSB is 0-19, but fig. 9 only shows the positions 0-9; it is also assumed here that the SSB interval parameter OF is 1, that is, the minimum interval between the positions OF any two adjacent SSBs sent by the network device is 1, that is, two SSBs can be transmitted in one time slot, for example, the SSBs in fig. 9 may be transmitted through the positions OF the black squares; in addition, it is assumed here that the numerical parameter Q is equal to 4. Therefore, as can be seen from the calculation result OF equation (1), when the SSB interval parameter OF is 1, if the calculation results OF the plurality OF SSBs are the same, it can be determined that the plurality OF SSBs have the QCL relationship, and conversely, the plurality OF SSBs do not have the QCL relationship. For example, three SSBs with location indices of 0, 4, and 8 of the SSB result in the same and thus have a QCL relationship, while two SSBs with location indices of 0 and 2 of the SSB result in different and thus do not have a QCL relationship.

Optionally, according to the calculation manner of the formula (1), other similar manners or formulas may also be adopted to determine the QCL index of the first SSB through deformation, derivation, and the like. For example, assuming that the SSB spacing parameter OF can only take 1 or 2, the QCL index OF the first SSB can also be determined by deforming equation (1). Specifically, if the position index of the first SSB is an even number, the result of modulo the SSB value parameter after dividing the position index of the first SSB by the SSB interval parameter is determined as the QCL index of the first SSB; if the location index of the first SSB is odd, the result of modulo the SSB value parameter after adding 1 or subtracting 1 to the location index of the first SSB and dividing by the SSB interval parameter is determined as the QCL index of the first SSB, that is, the QCL index of the first SSB is determined according to the following formula (2) or formula (3):

wherein, QCL is a QCL index OF the first SSB, P is a position index OF the first SSB, Q is the numerical parameter, and OF is the SSB interval parameter.

Alternatively, in the case that the SSB interval parameter OF may also take other values than 1 or 2, the determination may be performed by referring to the principle OF the above equation (2) or (3), and the embodiment OF the present application is not limited thereto.

In addition, for the position index of the first SSB, it may be indicated by a bitmap, which may include a plurality of bits, when calculated according to formula (1) or a similar formula, wherein the parameter P may be equal to the exact value of the position index of the first SSB, i.e., determined by all bits of the bitmap for indicating the position index of the first SSB; alternatively, the parameter P may also be equal to an approximate value or an alternative value of the position index of the first SSB, for example, may be equal to a value of a partial bit of a bitmap for indicating the position index of the first SSB. For example, assuming that Q OF is 4, the bitmap for indicating the position index OF the first SSB includes 5 bits in total, or includes more bits, and when the calculation is performed according to equation (1), the parameter P may be equal to the value indicated by the 5-bit bitmap, or may be equal to the value OF the lowest three bits in the 5-bit bitmap (i.e., PBCH DMRS sequence index), but the calculation result is unchanged regardless OF which value the parameter P uses.

It should be understood that the method 200 of the present embodiment may further include: the network device sends the first SSB to the terminal device. Specifically, the terminal device may receive the first SSB sent by the network device, and further, the terminal device may determine a location index and a QCL index of the first SSB, which is not limited in this embodiment of the application.

Therefore, according to the location index of the SSB, the SSB numerical parameter, and the SSB interval parameter, the method for transmitting the synchronization signal block according to the embodiment of the present application can determine QCL information of any SSB, and can correctly obtain QCL relationships between SSBs sent at different locations, thereby avoiding a joint operation between SSBs that do not have a QCL relationship.

Optionally, in the method 200, the terminal device or the network device may determine the QCL information of the first SSB according to at least three parameters, namely, the location index of the first SSB, the SSB value parameter, and the SSB interval parameter, and for convenience of distinction, the SSB value parameter is referred to as the first SSB value parameter. In contrast, the terminal device or the network device may further determine the QCL information of the first SSB only according to at least two parameters, i.e., the location index of the first SSB and the numerical parameter of the second SSB.

Specifically, the second SSB numerical parameter may be determined in various manners, for example, the terminal device may receive the second SSB numerical parameter sent by the network device; alternatively, the terminal device may autonomously determine the second SSB numerical parameter; alternatively, the second SSB value parameter may also be specified by a protocol, and the embodiment of the present application is not limited thereto.

It should be understood that the second SSB value parameter may be any value, i.e., the second SSB value parameter may have no specific meaning, e.g., the second SSB value parameter may be a value configured by a network device, which may be equal to any number. Or, the second SSB value parameter may also indicate a maximum number of candidate positions of SSBs included in a time window for transmitting an SSB included in the SS/PBCH burst set within a transmission window; alternatively, the second SSB value parameter may also be equal to the product between the first SSB value parameter and the SSB interval parameter in S210 in the method 200, that is, the product between the maximum number of SSBs having no QCL relationship in a transmission window and the SSB interval parameter, but the embodiment of the present application is not limited thereto.

In this embodiment of the present application, the process of determining the QCL information of the first SSB according to the location index of the first SSB and the second SSB numerical parameter is applicable to the relevant description in S210 in the method 200, that is, in the determination process, the second SSB numerical parameter replaces the product of the first SSB numerical parameter and the SSB interval parameter in S210, and for brevity, no further description is provided here.

Therefore, the process of determining the QCL information of the first SSB according to the location index of the first SSB and the numerical parameter of the second SSB saves at least one parameter compared to the process of determining the QCL information of the first SSB through at least three parameters, which can save overhead and simplify the operation process.

It should be understood that, in the various embodiments of the present application, the sequence numbers of the above-mentioned processes do not mean the execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
