An embodiment of the present disclosure provides a method for transmitting frequency band information, and fig. 2 is a flowchart illustrating a method for transmitting frequency band information according to an exemplary embodiment, and as shown in fig. 2, the method includes:

step S201, the ue sends, to the network device, an identifier of a radio frequency logical unit corresponding to a frequency band supported by the ue.

In some possible embodiments, the user equipment may send the identity of the radio frequency logic unit to the network equipment in a variety of ways.

For example:

the user equipment sends radio frequency capability to the network equipment, wherein the radio frequency capability comprises the identification of a radio frequency logic unit corresponding to a frequency band supported by the user equipment.

For another example:

the user equipment sends carrier aggregation capability to the network equipment, wherein the carrier aggregation capability comprises the identification of the radio frequency logic unit corresponding to the frequency band supported by the user equipment.

In some possible embodiments, the identification of the radio frequency logic unit corresponds to one transceiving path. For example: the identity of one radio frequency logic unit corresponds to one transceiver chain.

In some possible embodiments, each frequency band supported by the user equipment corresponds to an identity of a radio frequency logic unit. The identifiers of the radio frequency logic units corresponding to different frequency bands are different.

In some possible embodiments, when the bandwidth of a frequency band supported by the user equipment is greater than the set bandwidth, the frequency band corresponds to the identities of the plurality of radio frequency logic units. For example, when the user equipment supports band77 (its bandwidth is 900 MHz), band77 corresponds to the identities of a plurality of radio frequency logical units.

In some possible embodiments, the at least two frequency bands supported by the user equipment correspond to identities of the same radio frequency logic unit.

In some possible embodiments, the radio frequency logic unit is a transceiver chain, transceiver unit or antenna unit.

Step S202, the network equipment determines carrier aggregation configuration information of the user equipment according to the identification of the radio frequency logic unit.

In some possible embodiments, at least two frequency bands in the carrier aggregation configuration information determined by the network device correspond to identities of the same radio frequency logic unit.

In some possible embodiments, when setting carrier aggregation configuration information of carrier aggregation in a frequency band, the network device makes the user equipment complete data transceiving to each secondary cell (scell) by using as little radio frequency logic (for example, transceiver chain) as possible.

In step S203, the network device sends the carrier aggregation configuration information to the user equipment.

In one example:

the user equipment supports carrier aggregation of 5 carriers in the frequency band (inter band) in the FR1 frequency band, which is specifically denoted as CA_n1-n3-n5-n7-n78, namely the supported 5 frequency bands are n1, n3, n5, n7 and n78. The user equipment supports 5 transceiver chains, one corresponding to the 5 frequency bands.

The radio frequency capability sent by the user equipment to the network equipment includes:

the identity of the first transceiver chain corresponding to frequency band n1,

the identity of the second transceiver chain corresponding to frequency band n3,

the identity of the third transceiver chain corresponding to frequency band n5,

the identification of the fourth transceiver chain corresponding to frequency band n7,

identification of the fifth transceiver chain corresponding to frequency band n78.

And the network equipment determines carrier aggregation configuration information of the user equipment according to the radio frequency capability.

In another example:

the user equipment supports carrier aggregation of 4 carriers in the frequency band (inter band) in the FR1 frequency band, and the supported 4 frequency bands are frequency band nx1, frequency band nx2, frequency band nx3 and frequency band nx4. Frequency band nx1 and frequency band nx2 each correspond to a first transceiver chain, the identification of the first transceiver chain being U1, and frequency band nx3 and frequency band nx4 each correspond to a second transceiver chain, the identification of the second transceiver chain being U2.

the frequency band nx1 corresponds to the identity U1 of the first transceiver chain,

the frequency band nx2 corresponds to the identity U1 of the first transceiver chain,

the frequency band nx3 corresponds to the identity U2 of the first transceiver chain,

the frequency band nx4 corresponds to the identity U2 of the first transceiver chain.

After the network equipment receives the radio frequency capability, when the user equipment needs to use carrier aggregation in the frequency bands of 2 frequency bands, the frequency band corresponding to the same radio frequency logic unit is selected as far as possible under the conditions of protocol and actual scheduling conditions allow. For example, carrier aggregation configuration information of the ue is determined, and the carrier aggregation configuration information indicates frequency bands nx1 and nx2 or indicates frequency bands nx3 and nx4.

In the embodiment of the disclosure, the user equipment reports the identification of the radio frequency logic unit corresponding to the supported frequency band, so that the network equipment accurately acquires the radio frequency capability of the user equipment, thereby providing more reasonable carrier aggregation configuration information for the user equipment, improving the carrier aggregation transmission performance, improving the resource utilization rate and saving the power consumption of the user equipment.
