The quasi co-location configuration method, the quasi co-location QCL information determination method, and the apparatus thereof provided by the present application are described in detail below with reference to the accompanying drawings.
Referring to fig. 2, fig. 2 is a flowchart of a quasi-co-located configuration method according to an embodiment of the present disclosure. It should be noted that the quasi-co-location configuration method in the embodiments of the present application may be applied to a network device. As shown in fig. 2, the quasi-co-location configuration method may include, but is not limited to, the following steps.
Step 201, configuring a quasi co-location QCL relationship between a tracking reference signal TRS and a synchronization signal block SSB according to an index of the SSB; wherein, the beam width corresponding to the TRS is greater than or equal to the beam width corresponding to the SSB.
In order to accurately estimate frequency offset, time offset, doppler shift, doppler spread, and delay spread of a system, in order to reduce overhead, a Cell specific Reference Signal (CRS) is avoided, and a new Reference Signal, i.e., a tracking Reference Signal TRS is introduced. The receiving end can accurately estimate the channel parameters according to the TRS, and the demodulation accuracy is improved.
While the QCL (Quasi Co-located) configuration problem related to tracking reference signals (TRS for idle UEs) of a terminal device is still under discussion, beams configured for idle UEs are not necessarily consistent with narrow beams corresponding to a single SSB. For example, a beam (beam) corresponding to one TRS may be an equivalent beam formed by a combination of multiple beams occurring in the SSB.
In this embodiment of the present application, in a case that a tracking reference signal (TRS for idle UE) in an idle state of a terminal device is configured with a wide beam, that is, a beam width for a TRS is greater than or equal to a beam width corresponding to an SSB, for example, when a beam appearing in multiple SSBs corresponds to an equivalent beam representing one TRS, the network device in this embodiment of the present application may configure a quasi-co-located QCL relationship between the tracking reference signal TRS and the SSB according to an index of the SSB, that is, may tell the terminal device UE which ones of multiple beams of the SSB each TRS corresponds to, so that signaling overhead may be saved, thereby saving device power and avoiding resource waste.
It should be noted that, for a beam corresponding to one TRS, in the prior art, when configuring the quasi co-located QCL relationship between the TRS and the SSB, the network device indexes by indicating all SSBs corresponding to the TRS. For example, assuming that the index set of the SSB includes index 0, index 1, index 2, index 3, index 4, index 5, index 6, and index 7, and for a beam corresponding to one TRS, assuming that the beam corresponding to the TRS is composed of beams corresponding to index 0, index 1, index 2, and index 3, the network device in the prior art indicates that the beam corresponding to the SSB index 0, SSB index 1, SSB index 2, and SSB index 3 corresponds to the beam of the TRS to configure the QCL relationship between the TRS and SSB, and it can be seen that, in the prior art, the network device writes all of SSB index 0, SSB index 1, SSB index 2, and SSB index 3 in signaling during configuration, occupies signaling resources, so that signaling overhead is too large.
In order to further save signaling overhead, the embodiments of the present application may be configured by using the start index and the end index of the SSB. In an implementation manner, fig. 3 is a flowchart of another quasi co-location configuration method provided in an embodiment of the present application. It should be noted that the quasi-co-location configuration method in the embodiments of the present application may be applied to a network device. As shown in fig. 3, the quasi co-location configuration method of the embodiment of the present application may include, but is not limited to, the following steps.
Step 301, configuring a start index and an end index of an SSB corresponding to a TRS according to an index of a synchronization signal block SSB; wherein, the beam width corresponding to the TRS is greater than or equal to the beam width corresponding to the SSB.
For example, for a beam corresponding to a TRS, the network device according to the embodiment of the present application may configure a start index and an end index of an SSB corresponding to the TRS, so that the width of the TRS beam can be explicitly configured through the start index and the end index of the SSB. For example, assuming that the index set of the SSB includes index 0, index 1, index 2, index 3, index 4, index 5, index 6, and index 7, and for a beam corresponding to one TRS, index 0 may be configured as the starting index, and index 3 may be configured as the ending index, the beam beams corresponding to SSB index 0, SSB index 1, SSB index 2, and SSB index 3 are combined to form the beam of the TRS, that is, the width of the corresponding TRS beam is explicitly configured through SSB index 0, SSB index 1, SSB index 2, and SSB index 3.
In some embodiments of the present application, as shown in fig. 3, the quasi co-location configuration method may further include step 302. Wherein, step 302: the configured QCL relationship between the TRS and the SSB may be sent to the terminal device. That is, the network device may send the configured QCL relationship between the TRS and the SSB to the terminal device, so that the terminal device may determine the QCL reference signal of the TRS or the SSB according to the QCL relationship.
It should be noted that, multiple TRS resources for idle UEs may be configured, and multiple resources may be configured separately. In one implementation, the TRS is configured for a plurality of resources, and for each TRS resource, a quasi co-located QCL relationship between the TRS resource and the SSB may be configured according to an index of the synchronization signal block SSB. For example, for the example of configuring the QCL relationship between the TRS and the SSB in a manner of using the start index and the end index of the SSB, the start index and the end index of the SSB corresponding to each TRS resource may be configured separately for a plurality of TRS resource configurations. For example, assuming that the index set of the SSB includes index 0, index 1, index 2, index 3, index 4, index 5, index 6, and index 7, assuming that a first TRS resource and a second TRS resource are configured, index 0 may be configured as an SSB start index corresponding to the first TRS resource, index 3 may be configured as an SSB end index corresponding to the first TRS resource, index 4 is configured as an SSB start index corresponding to the second TRS resource, and index 5 is configured as an SSB end index corresponding to the second TRS resource, beam beams corresponding to SSB index 0, SSB index 1, SSB index 2, and SSB index 3 are combined to form a beam of the first TRS resource, that is, the width of the beam corresponding to the first TRS resource is explicitly configured through SSB index 0, SSB index 1, SSB index 2, and SSB index 3; the beam corresponding to the SSB index 4 and the SSB index 5 is combined to form the beam of the second TRS resource, that is, the width of the beam corresponding to the second TRS resource is explicitly configured by the SSB index 4 and the SSB index 5.
Therefore, the network device in the embodiment of the present application can configure the start index and the end index of the SSB corresponding to the TRS, so that the width of the TRS beam can be clearly configured through the start index and the end index of the SSB, and the relationship between the TRS and the SSB can be ensured while the index value written in the signaling is reduced, thereby further saving signaling overhead, further saving device power, and avoiding resource waste.
It should be noted that, in the NR network, after the terminal device initially accesses, the network device sends the SSB index actually sent to the terminal device in the form of a bitmap (bitmap). For the frequency range FR1, a maximum of 8 bits; but a maximum of 64 bitmaps for the frequency range FR 2. Therefore, for FR2, if full bitmap is used in the TRS for idle configuration, the signaling overhead is too large; especially in case multiple (e.g. n) TRS resources may be configured in FR2, the signaling overhead would be 64 × n. To further reduce signaling overhead, a preset number of bits of bitmap may be employed to configure the quasi co-located QCL relationship between the TRS and the SSB. In an implementation manner, fig. 4 is a flowchart of another quasi co-location configuration method provided in an embodiment of the present application. It should be noted that the quasi-co-location configuration method in the embodiments of the present application may be applied to a network device. As shown in fig. 4, the quasi co-location configuration method of the embodiment of the present application may include, but is not limited to, the following steps.
Step 401, configuring a quasi co-location QCL relationship between the TRS and the SSB based on a bitmap with a preset number of bits according to an index of the synchronization signal block SSB; wherein, the beam width corresponding to the TRS is greater than or equal to the beam width corresponding to the SSB.
In one implementation, the preset number may be 8. For example, in the case that the tracking reference signal (TRS for idle UE) of the terminal device in the idle state is in a wide beam configuration, that is, the beam width for the TRS is greater than or equal to the beam width corresponding to the SSB, for example, when beam correspondence appearing in a plurality of SSBs represents equivalent beam of one TRS, the quasi-co-located QCL relationship between the TRS and the SSB may be configured by a bitmap including 8 bits. In this way, the beam of a TRS can be known by a string of 8-bit numbers as to which of the beam beams of SSBs the beam of a TRS is composed, thereby greatly saving signaling overhead, further saving device power, and avoiding waste of resources. It should be further noted that the example that the bitmap provided in the embodiment of the present application is composed of 8 bits is only to provide an example for facilitating a person skilled in the art to understand the scheme of the present application, that is, the number of bits in the bitmap referred to in the embodiment of the present application may not be 8, for example, may be less than 8, or may be greater than 8, and may be negotiated according to an actual application situation, which is not specifically limited in the present application.
In one implementation, for the terminal device to receive information on the frequency range FR1, the network device may configure the bit value of each bit in the bitmap according to the index of the SSB; wherein bits in the bitmap are used to indicate the index of the SSB, and the bit value of each bit in the bitmap is used to indicate the quasi-co-located QCL relationship between the TRS and the SSB. For example, assuming that the bitmap is composed of 8 bits, assuming that the index set of the SSB includes index 0, index 1, index 2, index 3, index 4, index 5, index 6, and index 7, and for a beam corresponding to one TRS, assuming that the beam corresponding to the TRS is composed of beams corresponding to index 0, index 1, index 2, and index 3, the network device may configure the bit value on the corresponding bit in the bitmap to be 1 and the bit values corresponding to other bits in the bitmap to be 0 according to index 0, index 1, index 2, and index 3, for example, the bitmap composed of 8 bits may be configured to be "11110000", where the first bit to the fourth bit in the bitmap correspond to index 0, index 1, index 2, and index 3, respectively, the bit value on the first bit to the fourth bit in the bitmap is 1, which indicates that the beam corresponding to index 0, index 1, index 2, and index 3 corresponds to the beam corresponding to the TRS, thereby realizing the configuration of the QCL relationship between the TRS and the SSB.
It should be noted that, multiple TRS resources for idle UEs may be configured, and multiple resources may be configured separately. In one implementation, the TRS configures a plurality of resources, and for each TRS resource, the network device configures a quasi co-located QCL relationship between the TRS resource and the SSB according to an index of the synchronization signal block SSB. Optionally, for example, the QCL relationship between the TRS and the SSB is configured by using a bitmap with a preset number of bits, for multiple TRS resource configurations, for the terminal device receiving information in the frequency range FR1, the network device may configure the bit value of each bit in different bitmaps according to the index of the SSB. For example, assuming that the bitmap is composed of 8 bits, assuming that the index set of the SSB includes index 0, index 1, index 2, index 3, index 4, index 5, index 6, and index 7, assuming that the first TRS resource and the second TRS resource are configured, the beam corresponding to the first TRS resource is composed of beams corresponding to index 0, index 1, index 2, and index 3, and the beam corresponding to the second TRS resource is composed of beams corresponding to index 4, index 5, and index 6, the network device may configure a first bitmap corresponding to the first TRS resource according to index 0, index 1, index 2, and index 3, the bit value on the corresponding bit in the first bitmap is configured as 1, and the bit values corresponding to other bits in the first bitmap are configured as 0, for example, the first bitmap composed of 8 bits may be configured as "11110000", wherein the first bit to fourth bit in the first bitmap respectively correspond to index 0, index 3, index 1, index 2, and index 3, The bit value of the first bit to the fourth bit is 1, which indicates that the beam corresponding to the index 0, the index 1, the index 2 and the index 3 corresponds to the beam of the TRS; the network device may configure a second bitmap corresponding to a second TRS resource according to an index 4, an index 5, and an index 6, where a bit value of a corresponding bit in the second bitmap is configured to be 1, and a bit value of another bit in the second bitmap is configured to be 0, for example, the second bitmap composed of 8 bits may be configured to be "00001110", where fifth to seventh bits in the second bitmap correspond to the index 4, the index 5, and the index 6, respectively, and a bit value of the fifth to seventh bits is 1, which indicates that a beam corresponding to the TRS corresponds to the beam of the TRS corresponding to the index 4, the index 5, and the index 6, thereby implementing configuration of QCL relationships between different TRS resources and SSBs.
In one implementation, for the terminal device to receive information on the frequency range FR2, the network device may divide the index set of SSBs into a preset number of combinations; configuring a bit value of each bit in a bitmap; wherein each bit in the bitmap is used to represent an index of the SSB within the corresponding combination, and the bit value of each bit in the bitmap is used to represent a quasi-co-located QCL relationship between the TRS and the SSB.
Alternatively, for the terminal device to receive information on the frequency range FR2, the network device may divide the index set of SSBs into 8 combinations (groups), configure the bit value of each bit in the bitmap comprising 8 bits, wherein each bit in the bitmap is used to indicate the index of the SSB in the corresponding combination, and the bit value of each bit in the bitmap is used to indicate the quasi co-located QCL relationship between TRS and SSB.
For example, for the terminal device to receive information in the frequency range FR2, assuming that the bitmap is composed of 8 bits, assuming that the index set of the SSB includes 64 indices, i.e., index 0, index 1, index 2, i.e., index 62, and index 63, the network device may divide the index set of the SSB into 8 combinations, where the first combination includes indices 0 to index 7, the second combination includes indices 8 to index 15, the third combination includes indices 16 to index 23, the fourth combination includes indices 24 to index 31, the fifth combination includes indices 32 to index 39, the sixth combination includes indices 40 to index 47, the seventh combination includes indices 48 to index 55, and the eighth combination includes indices 56 to index 63. For a beam corresponding to one TRS, assuming that the beam corresponding to the TRS is composed of beams corresponding to indexes 24 to 31, the network device may configure a bit value on a corresponding bit in the bitmap to be 1 and a bit value corresponding to other bits in the bitmap to be 0 according to a relationship between the indexes 24 to 31 and the corresponding combinations, for example, the bitmap composed of 8 bits may be configured to be "00010000", where a fourth bit in the bitmap corresponds to a fourth combination, the fourth combination includes the indexes 24 to 31, and the bit value on the fourth bit is 1, which indicates that a beam corresponding to the indexes 24 to 31 corresponds to the beam of the TRS, thereby implementing configuration of a QCL relationship between the TRS and the SSB. Therefore, the index sets of the SSBs are grouped, and the bitmap is used to indicate which groups of corresponding beam beams are in the beam of the TRS, so that signaling overhead can be greatly reduced, the electric quantity of equipment can be further saved, and resource waste can be avoided.
It should be noted that, multiple TRS resources for idle UEs may be configured, and multiple resources may be configured separately. In one implementation, the TRS configures a plurality of resources, and for each TRS resource, the network device configures a quasi co-located QCL relationship between the TRS resource and the SSB according to an index of the synchronization signal block SSB. Optionally, for example, the QCL relationship between the TRS and the SSB is configured by using a bitmap with a preset number of bits, for multiple TRS resource configurations, for the terminal device receiving information in the frequency range FR2, the network device may configure the bit value of each bit in different bitmaps according to the index of the SSB. For example, for the terminal device to receive information in the frequency range FR2, assuming that the bitmap is composed of 8 bits, assuming that the index set of the SSB includes 64 indices, i.e., index 0, index 1, index 2, i.e., index 62, and index 63, the network device may divide the index set of the SSB into 8 combinations, where the first combination includes indices 0 to index 7, the second combination includes indices 8 to index 15, the third combination includes indices 16 to index 23, the fourth combination includes indices 24 to index 31, the fifth combination includes indices 32 to index 39, the sixth combination includes indices 40 to index 47, the seventh combination includes indices 48 to index 55, and the eighth combination includes indices 56 to index 63. Assuming that the first TRS resource and the second TRS resource are configured, the beam corresponding to the first TRS resource is composed of beams corresponding to indexes 24 to 31, and the beam corresponding to the second TRS resource is composed of beams corresponding to indexes 40 to 47, the network device may configure the bit value of the corresponding bit in the first bitmap to be 1 and the bit values of the other bits in the first bitmap to be 0 according to the relationship between the indexes 24 to 31 and the corresponding combinations, for example, the first bitmap composed of 8 bits may be configured to be "00010000", where the fourth bit in the first bitmap corresponds to a fourth combination, the fourth combination includes the indexes 24 to 31, and the bit value of the fourth bit is 1, which indicates that the beam corresponding to the indexes 24 to 31 corresponds to the beam of the first TRS. The network device may configure the bit value of the corresponding bit in the second bitmap to be 1 and the bit values of the other bits in the second bitmap to be 0 according to the relationship between the index 40 to the index 47 and the corresponding combination, for example, the second bitmap composed of 8 bits may be configured to be "00000100", wherein the sixth bit in the second bitmap corresponds to the sixth combination, the sixth combination includes the index 40 to the index 47, and the bit value of the sixth bit is 1, which indicates that the beam corresponding to the index 40 to the index 47 corresponds to the beam of the second TRS, thereby implementing the configuration of the QCL relationship between different TRSs and SSBs. Therefore, the index sets of the SSBs are grouped, and the bitmap is used to indicate which groups of corresponding beam beams are in the beam of the TRS, so that signaling overhead can be greatly reduced, the electric quantity of equipment can be further saved, and resource waste can be avoided.
It should be further noted that, in the embodiment of the present application, the grouping manner of the index sets of the SSBs is only an example description given for facilitating understanding of the present application by a person skilled in the art, that is, the grouping manner may also be specified according to a pre-negotiation, as a possible implementation manner, the index sets of the SSBs may be grouped into 8 groups, and the number of indexes in each group may be the same or may not be the same, which is not specifically limited in the present application.
In some embodiments according to the present application, as shown in fig. 4, the quasi co-location configuration method may further include step 402. Wherein, step 402: the configured QCL relationship between the TRS and the SSB may be sent to the terminal device. That is, the network device may send the configured QCL relationship between the TRS and the SSB to the terminal device, so that the terminal device may determine the QCL reference signal of the TRS or the SSB according to the QCL relationship.
By implementing the embodiment of the application, the beam of one TRS can be known to be formed by which beam beams of the SSBs through a string of 8-bit numbers, so that the signaling overhead can be greatly saved, the electric quantity of equipment is further saved, and the resource waste is avoided.
It can be understood that the foregoing embodiments describe implementation manners of the quasi co-location configuration method according to the embodiments of the present application from a network device side. The embodiment of the present application further provides a method for determining quasi co-located QCL information, and an implementation manner of the method for determining quasi co-located QCL information will be described below from a terminal device side. Referring to fig. 5, fig. 5 is a flowchart of a method for determining quasi co-located QCL information according to an embodiment of the present application. It should be noted that the quasi-co-located QCL information determining method according to the embodiment of the present application may be applied to a terminal device. As shown in fig. 5, the quasi-co-located QCL information determination method may include, but is not limited to, the following steps.
Step 501, receiving a quasi co-located QCL relationship between a tracking reference signal TRS and a synchronization signal block SSB configured by a network device.
In the embodiment of the present application, the beam width corresponding to the TRS is greater than or equal to the beam width corresponding to the SSB.
Alternatively, in the case that the tracking reference signal (TRS for idle UE) in the idle state of the terminal device is in a wide beam configuration, that is, the beam width for the TRS is greater than or equal to the beam width corresponding to the SSB, for example, when a beam appearing in a plurality of SSBs corresponds to an equivalent beam representing one TRS, the network device may configure the quasi-co-located QCL relationship between the tracking reference signal TRS and the SSB according to the index of the synchronization signal block SSB.
In order to further save signaling overhead, in one implementation, the network device may configure a start index and an end index of the SSB corresponding to the TRS according to an index of the synchronization signal block SSB; wherein, the beam width corresponding to the TRS is greater than or equal to the beam width corresponding to the SSB. For example, for a beam corresponding to a TRS, the network device according to the embodiment of the present application may configure a start index and an end index of an SSB corresponding to the TRS, so that the width of the TRS beam can be explicitly configured through the start index and the end index of the SSB. For example, assuming that the index set of the SSB includes index 0, index 1, index 2, index 3, index 4, index 5, index 6, and index 7, and for a beam corresponding to one TRS, index 0 may be configured as the starting index, and index 3 may be configured as the ending index, the beam beams corresponding to SSB index 0, SSB index 1, SSB index 2, and SSB index 3 are combined to form the beam of the TRS, that is, the width of the corresponding TRS beam is explicitly configured through SSB index 0, SSB index 1, SSB index 2, and SSB index 3.
In order to further save signaling overhead, in an implementation manner, the network device may configure a quasi co-located QCL relationship between the TRS and the SSB based on a bitmap with a preset number of bits according to an index of the synchronization signal block SSB; wherein, the beam width corresponding to the TRS is greater than or equal to the beam width corresponding to the SSB. Alternatively, the preset number may be 8. For example, in the case that the tracking reference signal (TRS for idle UE) of the terminal device in the idle state is in a wide beam configuration, that is, the beam width for the TRS is greater than or equal to the beam width corresponding to the SSB, for example, when the beam correspondence appearing in multiple SSBs represents an equivalent beam of one TRS, the network device may configure the quasi-co-located QCL relationship between the TRS and the SSB through a bitmap including 8 bits. In this way, the beam of a TRS can be known by a string of 8-bit numbers as to which of the beam beams of SSBs the beam of a TRS is composed, thereby greatly saving signaling overhead, further saving device power, and avoiding waste of resources.
In one implementation, for the terminal device to receive information on the frequency range FR1, the network device may configure the bit value of each bit in the bitmap according to the index of the SSB; wherein bits in the bitmap are used to indicate the index of the SSB, and the bit value of each bit in the bitmap is used to indicate the quasi-co-located QCL relationship between the TRS and the SSB. For example, assuming that the bitmap is composed of 8 bits, assuming that the index set of the SSB includes index 0, index 1, index 2, index 3, index 4, index 5, index 6, and index 7, and for a beam corresponding to one TRS, assuming that the beam corresponding to the TRS is composed of beams corresponding to index 0, index 1, index 2, and index 3, the network device may configure the bit value on the corresponding bit in the bitmap to be 1 and the bit values corresponding to other bits in the bitmap to be 0 according to index 0, index 1, index 2, and index 3, for example, the bitmap composed of 8 bits may be configured to be "11110000", where the first bit to the fourth bit in the bitmap correspond to index 0, index 1, index 2, and index 3, respectively, the bit value on the first bit to the fourth bit in the bitmap is 1, which indicates that the beam corresponding to index 0, index 1, index 2, and index 3 corresponds to the beam corresponding to the TRS, thereby realizing the configuration of the QCL relationship between the TRS and the SSB.
In one implementation, for the terminal device to receive information on the frequency range FR2, the network device may divide the index set of SSBs into a preset number of combinations; configuring a bit value of each bit in a bitmap; wherein each bit in the bitmap is used to represent an index of the SSB within the corresponding combination, and the bit value of each bit in the bitmap is used to represent a quasi-co-located QCL relationship between the TRS and the SSB.
Alternatively, for the terminal device to receive information on the frequency range FR2, the network device may divide the index set of SSBs into 8 combinations (groups), configure the bit value of each bit in the bitmap comprising 8 bits, wherein each bit in the bitmap is used to indicate the index of the SSB in the corresponding combination, and the bit value of each bit in the bitmap is used to indicate the quasi co-located QCL relationship between TRS and SSB.
For example, for the terminal device to receive information in the frequency range FR2, assuming that the bitmap is composed of 8 bits, assuming that the index set of the SSB includes 64 indices, i.e., index 0, index 1, index 2, i.e., index 62, and index 63, the network device may divide the index set of the SSB into 8 combinations, where the first combination includes indices 0 to index 7, the second combination includes indices 8 to index 15, the third combination includes indices 16 to index 23, the fourth combination includes indices 24 to index 31, the fifth combination includes indices 32 to index 39, the sixth combination includes indices 40 to index 47, the seventh combination includes indices 48 to index 55, and the eighth combination includes indices 56 to index 63. For a beam corresponding to one TRS, assuming that the beam corresponding to the TRS is composed of beams corresponding to indexes 24 to 31, the network device may configure a bit value on a corresponding bit in the bitmap to be 1 and a bit value corresponding to other bits in the bitmap to be 0 according to a relationship between the indexes 24 to 31 and the corresponding combinations, for example, the bitmap composed of 8 bits may be configured to be "00010000", where a fourth bit in the bitmap corresponds to a fourth combination, the fourth combination includes the indexes 24 to 31, and the bit value on the fourth bit is 1, which indicates that a beam corresponding to the indexes 24 to 31 corresponds to the beam of the TRS, thereby implementing configuration of a QCL relationship between the TRS and the SSB. Therefore, the index sets of the SSBs are grouped, and the bitmap is used to indicate which groups of corresponding beam beams are in the beam of the TRS, so that signaling overhead can be greatly reduced, the electric quantity of equipment can be further saved, and resource waste can be avoided.
Step 502, determining a QCL reference signal of the TRS or the SSB according to the QCL relationship.
By implementing the embodiment of the application, when the tracking reference signal (TRS for idle UE) of the terminal device is configured with a wide beam, that is, for the beam width of the TRS being greater than or equal to the beam width corresponding to the SSB, the quasi co-located QCL relationship between the tracking reference signal TRS and the SSB is configured by the network device according to the index of the SSB, so that signaling overhead can be saved, thereby saving device power and avoiding resource waste.
