In some embodiments, each bit position also has a one-to-one correspondence with a frequency band group. Optionally, the relationship between the Nth bit position and the frequency band group is determined by the number of frequency bands and the frequency band identifier.

It should be noted that the first sub-information and the second sub-information in the embodiment of the present disclosure are two independent pieces of information. That is, the terminal needs to send the first sub-information and the second sub-information separately. For example, the terminal sends the first sub-information and the second sub-information at the same time, or the terminal first sends the first sub-information and then sends the second sub-information, or the terminal first sends the second sub-information and then sends the first sub-information.

In some embodiments, the first sub-information includes a third number of bits, each bit being used to indicate whether the frequency band group corresponding to the bit supports independent beam management. In the disclosed embodiment, each bit is in a one-to-one correspondence with the frequency band group, and the bit also corresponds to independent beam management, so the bit can indicate whether the frequency band group corresponding to each bit supports independent beam management.

In some embodiments, the third number refers to the number of groups obtained after the plurality of frequency bands are grouped in pairs. Optionally, the first number is L*(L–1)/2.

It should be noted that in the embodiment of the present disclosure, the seventh value is different from the eighth value, that is, if the seventh value is 1, used to indicate that the frequency band group corresponding to the bit supports unified beam management, then the eighth value is 0, used to indicate that the frequency band group corresponding to the bit does not support unified beam management.

In some embodiments, each bit position also has a one-to-one correspondence with a frequency band group. Optionally, the relationship between the Nth bit position and the frequency band group is determined by the number of frequency bands and the frequency band identifier. For example, the correspondence between bit N and each pair of frequency band combinations is N=x*(2*L–x–1)/2+y–x–1. Where x and y are both frequency band identifiers, where x<y, and x is greater than or equal to 0.

In some embodiments, the fourth number refers to the number of groups obtained after the plurality of frequency bands are grouped in pairs. Optionally, the first number is L*(L–1)/2. Wherein, L is the number of the plurality of frequency bands. Alternatively, L can also be understood as the number of frequency bands forming a frequency band group.

In addition, the first bit 0 corresponds to the frequency band group consisting of frequency band 0 and frequency band 1, the second bit 1 corresponds to the frequency band group consisting of frequency band 0 and frequency band 2, and the third bit 2 corresponds to the frequency band group consisting of frequency band 1 and frequency band 2.

FIG6 is a flow chart of an indication method according to an embodiment of the present disclosure. As shown in FIG6 , the embodiment of the present disclosure relates to an indication method, and the method includes:

Step S6101, when the terminal reports the carrier aggregation between frequency bands through the existing signaling beamManagementType-r16 and beamManagementType-CBM-r17 and supports independent beam management and unified beam management at the same time, the terminal needs to further report the beam management type supported by each pair of frequency band combinations (x, y) in the carrier aggregation between the supported frequency bands (such as x, y, z).

In some embodiments, new signaling is introduced, which is a bitmap signaling, and each bit is used to indicate the beam management type supported by each pair of frequency band combinations in inter-frequency band carrier aggregation.

In some embodiments, if the frequency band pair (x, y) supports independent beam management, the corresponding bit is set to ‘1’, and if it supports unified beam management, the corresponding bit is set to ‘0’. Therefore, the size of the new bitmap signaling is L*(L–1)/2, L is the number of frequency bands included in the inter-band carrier aggregation, and the corresponding relationship between bit N and each pair of frequency band combinations is N=x*(2*L–x–1)/2+y–x–1, where x<y, x is at least 0, representing the first frequency band entry.

In some embodiments, when the terminal reports beamManagementType-r16 and beamManagementType-CBM-r17 at the same time, if the terminal supports pure IBM and CBM, all bits of the new signaling are set to 1 or 0; if the terminal supports mixed IBM and CBM beam management, the corresponding bits are set to 1 or 0.

In some embodiments, when the network receives both beamManagementType-r16 and beamManagementType-CBM-r17 signaling at the same time, and all bits of the new signaling are set to 1 or 0, the network considers that the terminal supports pure IBM and CBM beam management, and the network only configures IBM or CBM beam management within the carrier aggregation.

When the network receives both beamManagementType-r16 and beamManagementType-CBM-r17 signaling at the same time, and not all bits of the new signaling are set to 1 or 0, the network considers that the terminal supports mixed IBM and CBM beam management, and the network schedules the supported beam management mode according to the frequency band reported by the terminal.

When the network receives only one of the two signalings, beamManagementType-r16 or beamManagementType-CBM-r17, the network ignores the new signaling and considers that the terminal only supports pure IBM or pure CBM.

In some embodiments, two new bitmap signals are introduced, one for indicating that the terminal supports the band pair of IBM, and the other for indicating that the terminal supports the band pair of CBM. The sizes of the two new bitmap signals are both L*(L–1)/2, where L is the number of bands included in the inter-band carrier aggregation, and the corresponding relationship between bit N and each pair of band combinations is N=x*(2*L–x–1)/2+y–x–1, where x<y, and x is at least 0, representing the first band entry.

In some embodiments, when the terminal reports beamManagementType-r16 and beamManagementType-CBM-r17 at the same time, the terminal reports the frequency band pairs supporting IBM and CBM respectively through two new signalings. If the same bit N of the two new signalings is set to 1, it indicates that the terminal supports both IBM and CBM on this frequency band pair. The configuration depends on network scheduling. If only one of the same bit N in the two signalings is set to 1, it indicates that the terminal only supports IBM or CBM on this frequency band, and the network needs to schedule according to the terminal's report.

In some embodiments, when the network receives both beamManagementType-r16 and beamManagementType-CBM-r17 signalings and two new signalings at the same time, if the same bit N of the two new signalings is set to 1, it indicates that the terminal supports both IBM and CBM on this frequency band pair, and the network can configure both IBM and CBM on this frequency band pair. If only one of the same bit N of the two signalings is set to 1, it indicates that the terminal only supports IBM or CBM on this frequency band, and the network needs to schedule according to the report of the terminal.

When the network receives only one of the two signalings, beamManagementType-r16 or beamManagementType-CBM-r17, the network ignores the new signaling and considers that the terminal only supports pure IBM or pure CBM.
