Referring to fig. 5, fig. 5 is a flowchart of another method for reporting transceiving capability according to an embodiment of the present disclosure. As shown in fig. 5, the method is performed by the network side device, and the method may include, but is not limited to, the following steps:

s51: and the receiving terminal equipment responds to the determination that the receiving terminal equipment needs to use a plurality of frequency bands to transmit and receive simultaneously, and reports capability indication information, wherein the capability indication information is used for indicating whether the terminal equipment has the capability of using the plurality of frequency bands to transmit and receive simultaneously, and the plurality of frequency bands comprise at least one first frequency band for transmitting and at least one second frequency band for receiving.

In the embodiment of the disclosure, the network side device may receive capability indication information reported by the terminal device when determining that a plurality of frequency bands need to be used for transmitting and receiving simultaneously, where the capability indication information is used to indicate whether the terminal device has the capability of transmitting and receiving simultaneously by using the plurality of frequency bands, and the plurality of frequency bands include at least one first frequency band for transmitting and at least one second frequency band for receiving.

Therefore, the terminal equipment supports reporting of the capability indication information, and the network side equipment can adjust information transceiving of corresponding frequency bands according to whether the terminal equipment has the capability of transceiving simultaneously by using a plurality of frequency bands so as to avoid transceiving interference among the frequency bands.

In the exemplary embodiment, in order to increase transmission bandwidth and improve throughput in LTE and NR, a large number of band combinations, such as carrier aggregation (Carrier Aggregation), dual connection (Dual Connectivity), and the like, including band combinations of two bands and a plurality of bands are introduced. Taking two-Band carrier aggregation ca_na-nB as an example, when Band (Band) nA transmission and Band nB reception cannot be performed simultaneously due to an inter-Band interference problem, the terminal reports the capability to the base station, thereby limiting the Band nA transmission and Band nB reception to be performed simultaneously. However, only the simultaneous transceiving capability of the combination of TDD-TDD (TDD band and TDD band, hereinafter the same) and TDD-FDD (TDD band and FDD band, hereinafter the same) is defined, and the simultaneous transceiving capability of the combination of FDD-FDD (FDD band and FDD band, hereinafter the same) is not defined.

In the embodiment of the disclosure, the simultaneous transceiving capability is not defined for the FDD-FDD frequency band combination in CA and DC, so that transceiving interference between frequency bands cannot be avoided by partial FDD-FDD frequency band combination.

The embodiment of the disclosure provides a method for reporting the simultaneous receiving and transmitting capability of a terminal device supporting frequency band combination, which comprises CA, DC and the like.

The format of the simultaneous transceiving capability report is as described in the embodiment, and in the embodiment, NR CA will be taken as an example.

bitmap= (0, …, 0), bits are sharedBit, bit 0 indicates whether the band combination supports simultaneous transceiving capability, followed by +.>The bit indicates which combined transmit and receive bands support simultaneous transmissions. Taking 4band CA as an example, there is a total of +. >The bits are as follows:
