The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

The character "/" generally indicates that the context-dependent object is an "or" relationship. The singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

It is further understood that the terms "first," "second," and the like are used to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish one type of information from another and do not denote a particular order or importance. Indeed, the expressions "first", "second", etc. may be used entirely interchangeably. For example, a first carrier frequency band may also be referred to as a second carrier frequency band, and similarly, a second carrier frequency band may also be referred to as a first carrier frequency band without departing from the scope of the present disclosure.

It will be further understood that although operations are depicted in the drawings in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. In certain circumstances, multitasking and parallel processing may be advantageous.

It should be noted that, all actions of acquiring signals, information or data in the present application are performed under the condition of conforming to the corresponding data protection rule policy of the country of the location and obtaining the authorization given by the owner of the corresponding device.

Along with the development of communication technology, the communication information transmitted in the communication process is gradually changed from text information into image information, audio information and video information, so as to adapt to the increasing communication information transmission requirement, and the communication network speed or the communication capacity needs to be improved to improve the communication efficiency.

The related art method for improving the network speed or capacity mainly comprises the following steps: increase the number of base stations, improve spectral efficiency, and increase spectral bandwidth. The cost consumed for increasing the number of base stations and improving the spectrum efficiency is large, so that the communication network speed or capacity is generally improved by adopting a mode of increasing the spectrum bandwidth. For example, the frequency bands of 2G, 3G and Wifi networks may be employed in 4G communications, and the spectrum bandwidth is increased by amplifying new frequency bands in 5G communications.

However, since LTE (Long Term Evolution, long term evolution of universal mobile telecommunication technology) is a long term evolution technology, bandwidth requirements in communication deployment have been planned in earlier communication protocols, and if bandwidth is directly enlarged, downward protocols, devices, terminals, etc. are not compatible. In order to meet the transmission requirements of the downlink peak speed and the uplink peak speed in the communication process, a larger transmission bandwidth needs to be provided, and for example, if the requirement of the downlink peak speed of the LTE-A of 1Gbps and the uplink peak speed of 500Mbps needs to be met, the transmission bandwidth of 100MHz at maximum needs to be provided. Based on the scarcity of large bandwidth contiguous spectrum resources, CA (Carrier aggregation ) approaches are proposed to obtain a larger transmission bandwidth through multiple contiguous or non-contiguous component carrier aggregation, thereby obtaining higher peak rate and throughput.

In LTE and NR (New Radio) technologies, in order to increase transmission bandwidth and improve throughput, CA technology is introduced to perform a large number of frequency band combinations, so as to obtain a larger transmission bandwidth. Normally, during CA, there is no overlapping between frequency ranges, but there are exceptional cases, for example, in CA-N5-N8, when carriers in the N5 band and the N8 band are fused, the frequency ranges of NR band N5 and NR band N8 are as follows:

referring to the above table, in the CA process, DL (downlink) transmission of N5 and UL (Up-Link, uplink) transmission of N8 are described in: the 880MHz-894MHz frequency bands are overlapped, so serious interference can occur in a CA scene, and gain cannot be brought in the CA scene compared with a single carrier scene.

Based on the problem of transmission interference caused by overlapping frequency ranges in the CA procedure in the related art, the present application provides a method for indicating carrier aggregation capability, and fig. 1 is a flowchart of a method for indicating carrier aggregation capability according to an exemplary embodiment, and as shown in fig. 1, the method is performed by a UE (user equipment), and includes the following steps.

In step S101, it is determined that there are a plurality of designated carrier bands with overlapping spectrums among a plurality of carrier bands supported by the UE.

The relevant communication protocol defines an uplink Frequency Range, a downlink Frequency Range and a duplex mode of each carrier under each Frequency Range number, for example, the following table is a Frequency Range list of Frequency ranges of 5g f 1 (Frequency Range);

referring to the table, the uplink frequency range, the downlink frequency range and the duplex mode corresponding to the carrier signals of each frequency band number are fixed, and the uplink frequency range and the downlink frequency range of each carrier signal are different. In general, the UE does not need to support carrier signals in a full frequency band, and before the UE leaves the factory, different communication chips can be assembled for the UE based on the purpose of the UE, so that the UE adapts to carrier signals in different frequency bands, and therefore carrier frequency bands supported by different types of UEs are different. For example, in this embodiment, a frequency band number list may be configured for the UE, and the list is used to record the frequency band numbers supported by the UE, and an uplink frequency range, a downlink frequency range, and a duplex mode corresponding to each frequency band number. The number of the frequency band supported by the UE may be one or more.

In the frequency band number list corresponding to the UE, the frequency band numbers supported by the UE are recorded based on the UE communication chip and the configuration of the UE, and the uplink frequency range and/or the downlink frequency range of the carrier signal corresponding to each frequency band number may overlap, so that serious interference is generated in the CA process of the UE, and the CA gain cannot be brought. Therefore, in this embodiment, the UE may compare the uplink frequency range and the downlink frequency range of each carrier signal based on the above-mentioned frequency band number list, so as to determine whether there are a plurality of designated carrier frequency bands with overlapping frequency spectrums in the frequency band numbers supported by the UE. When comparing the frequency ranges, the carrier signals supported by the UE are compared in pairs, and the comparison of the frequency ranges does not need to distinguish between uplink transmission and downlink transmission. For example, when comparing the a band with the B band, it is necessary to compare the uplink frequency range of the a band with the uplink frequency range and the downlink frequency range of the B band, and compare the downlink frequency range of the a band with the uplink evaluation frequency range and the downlink frequency range of the B band to determine whether there is spectrum overlap.

And when the carrier frequency bands with overlapped frequency spectrums exist in the carrier frequency bands supported by the UE, determining the two carrier frequency bands with overlapped frequency spectrums as the appointed carrier frequency bands. It should be noted that, in multiple carrier frequency bands supported by the same UE, there may be multiple frequency ranges with overlapping spectrums, for example, the UE supports carrier signals of N5, N8, and N26, where the frequency ranges of NR band N5, NR band N8, and NR band N26 are as follows:

n8 UL and N5 DL overlap in a plurality of carrier frequency bands supported by the UE, N8 UL and N26 DL overlap, and a plurality of designated carrier frequency bands in the UE correspond to the carrier frequency bands corresponding to N5, N8 and N26.

It should be noted that, in this embodiment, when the primary connection between the UE and the network device is established, a plurality of designated carrier frequency bands in the UE may be determined based on the frequency band number list; before the UE leaves the factory, the frequency ranges may be compared based on the recorded frequency range number list to determine a plurality of designated carrier frequency ranges, and the designated carrier frequency ranges are recorded in the UE, and the plurality of designated carrier frequency ranges are determined by referring to the recording information.

In step S102, capability indication information is sent to the network device, where the capability indication information is used to indicate an implementation method supported by the terminal device, and the implementation method is used to avoid transceiver interference between multiple designated carrier frequency bands in the carrier aggregation process.

When carrier aggregation is carried out between two specified carrier frequency bands with overlapped frequency spectrums, serious interference can occur, so that the aggregation of carrier signals can not be realized, and the effect of increasing the frequency spectrum bandwidth is achieved. Therefore, transmission of a plurality of designated carrier frequency bands needs to be limited to avoid interference caused by spectrum overlapping in the CA process.

In this embodiment, after determining that a plurality of designated carrier frequency bands with overlapping frequency spectrums exist in a plurality of carrier frequency bands supported by the UE through the above steps, the UE determines, based on the current configuration, an implementation method capable of avoiding transceiver interference in a CA process, and sends capability indication information to the network device according to the implementation method, where the capability indication information is used to indicate the implementation method supported by the UE. The implementation method is used for avoiding receiving and transmitting interference caused by spectrum overlapping in the CA process, and can comprise the steps of shielding the receiving and transmitting of two carriers with overlapped spectrums, adjusting the receiving and transmitting time of the carriers with overlapped spectrums, shielding the receiving and transmitting of one carrier in the two carriers with not allowed to be overlapped, allowing the receiving and transmitting of the other carrier, and adjusting the frequency range of the carrier with overlapped spectrums so that the adjusted carriers cannot be overlapped in spectrum. The implementation method is not limited in this embodiment.

In this embodiment, when the UE establishes a communication connection with the base station, the UE may report carrier aggregation capability of the UE to the base station (network device) by sending capability indication information; and the capability indication information can be reported to the base station when the UE has corresponding carrier aggregation requirements. The base station can send the carrier signal corresponding to the frequency band number to the UE according to the capability indication information reported by the UE, so that the UE realizes carrier based on the carrier signal and the carrier aggregation capability of the UE.

Optionally, in an embodiment, the capability indication information includes a capability bitmap, where the capability bitmap indicates an implementation method supported by the terminal device through a bit value.

For example, in this embodiment, in order to improve efficiency of reporting capability of the UE, a plurality of implementation methods may be numbered in the UE, and capability indication information may be reported to the base station according to a capability bitmap. For example, in general, there are 4 implementation methods for avoiding transceiver interference in various types of UEs, where the UE supports the first and third implementation methods based on its own capability, and then the capability indication information of itself may be reported through a capability bitmap, where in the capability bitmap, a "1" is used to indicate the implementation method supported by the UE, and a "0" is used to indicate the implementation method not supported by the UE, and the capability bitmap reported by the UE is "1010"; if the UE supports the first and second implementation methods, the capability bitmap reported by the UE is "1100".

Fig. 2 is a flowchart illustrating a method of indicating carrier aggregation capability according to an exemplary embodiment, as shown in fig. 2, applied to a UE, the method including the following steps.

In step S201, it is determined that there are a plurality of designated carrier bands with overlapping spectrums among a plurality of carrier bands supported by the UE.

For example, in this embodiment, the manner of determining the plurality of designated carrier frequency bands is the same as that in the step S101, and reference may be made to the step S101, which is not repeated.

In step S202, capability indication information is sent to the network device, where the capability indication information is used to indicate an implementation method supported by the terminal device, and the implementation method is used to avoid transceiver interference between multiple designated carrier frequency bands in the carrier aggregation process.

For example, the manner of sending the capability indication information in this embodiment is the same as that in step S102, and reference may be made to step S102, which is not described in detail.

Optionally, in an embodiment, the plurality of designated carrier frequency bands includes a first carrier frequency band and a second carrier frequency band, and there is a spectrum overlap between a first downlink spectrum of the first carrier frequency band and a second uplink spectrum of the second carrier frequency band, and the implementation method includes at least one of the following;

In this embodiment, there is spectrum overlap between the first carrier frequency band and the second carrier frequency band in the UE, where there is spectrum overlap between the first downlink spectrum of the first carrier frequency band and the second uplink spectrum of the second carrier frequency band. The implementation manner for avoiding the inter-band receiving-transmitting interference of a plurality of designated carriers in the carrier aggregation process in the UE comprises at least one of the following steps:

(1) For the first downlink spectrum transmission of the first carrier frequency band and the second uplink spectrum transmission of the second carrier frequency band which are overlapped in the UE, the UE determines to support the first downlink spectrum transmission and not support the second uplink spectrum transmission based on the configuration of the UE. For example, the first carrier frequency band is N5 in the frequency band table, and the second carrier frequency band is N8 in the frequency band table, and the UE supports UL-N5, DL-N5 and DL-N8;

(2) For the first downlink spectrum transmission of the first carrier frequency band and the second uplink spectrum transmission of the second carrier frequency band which are overlapped in the UE, the UE determines to support the second uplink spectrum transmission and not support the first downlink spectrum transmission based on self configuration. For example, the first carrier frequency band is N5 in the frequency band table, and the second carrier frequency band is N8 in the frequency band table, and the UE supports UL-N5, UL-N8 and DL-N8;

(3) For the first downlink spectrum transmission of the first carrier frequency band and the second uplink spectrum transmission of the second carrier frequency band which are overlapped in the UE, interference problems caused by simultaneous transmission are avoided by limiting two spectrum transmission receiving and transmitting time, for example, the first carrier frequency band is N5 in the frequency band table, the second carrier frequency band is N8 in the frequency band table, the transmission time of DL-N5 and UL-N8 is limited, the transmission of DL-N5 is allowed in the time range of N1-N2, the transmission of UL-N8 is not allowed, the transmission of UL-N8 is allowed in the time range of N3-N4, and the transmission of DL-N5 is not allowed;

(4) In this embodiment, a special filter may be configured in the UE to adjust the frequency range of the carrier, so that no spectrum overlap occurs between the adjusted specified carrier frequency bands. And for the first downlink frequency spectrum transmission of the first carrier frequency band and the second uplink frequency spectrum transmission of the second carrier frequency band which are overlapped in the UE, adjusting the frequency range of the first downlink frequency spectrum and/or the frequency range of the second uplink frequency spectrum through a filter in the UE, so that the adjusted frequency range of the first downlink frequency spectrum and/or the adjusted frequency range of the second uplink frequency spectrum cannot be overlapped, and receiving and transmitting interference is avoided. For example, the first carrier frequency band is N5 in the frequency band table, and the second carrier frequency band is N8 in the frequency band table, where a range of the first downlink spectrum transmission of N5 is: 869MHz-894MHz; the range of the first uplink spectrum transmission of N8 is: 880MHz to 915MHz. The transmission range of the first downlink spectrum can be adjusted by a filter to: 869MHz-878MHz, and/or adjusting the transmission range of the second uplink spectrum to: 900MHz-915MHz, so that there is no spectrum overlapping designated carrier band in the UE.

Optionally, in one embodiment, defining that there is no overlap between the frequency range of the first downlink spectrum and the frequency range of the second uplink spectrum includes:

By way of example, in this embodiment, by installing a filtering apparatus for adjusting a frequency range in a UE, the filtering apparatus may adjust and filter a specified frequency spectrum range, and adjust a frequency range of an uplink spectrum or a downlink spectrum, where there is no overlap between a frequency range defining a first downlink spectrum and a frequency range defining a second uplink spectrum, including:

(1) The frequency range of the first downlink frequency spectrum is adjusted by a first filtering device to generate a first appointed downlink frequency spectrum, the frequency range of the first appointed downlink frequency spectrum and the frequency range of the second uplink frequency spectrum are not overlapped, so that the UE supports first uplink frequency spectrum transmission, first appointed downlink frequency spectrum transmission, second uplink frequency spectrum transmission and second downlink frequency spectrum transmission, for example, a first carrier frequency band is N5 in the frequency band table, a second carrier frequency band is N8 in the frequency band table, the first appointed downlink frequency spectrum is DL-N5r, and after being adjusted by the first filtering device, the UE supports: N5-DL, DL-N5r, UL-N8 and DL-N8;

(2) The frequency range of the second uplink frequency spectrum is adjusted by a second filtering device to generate a second appointed uplink frequency spectrum, the frequency range of the second appointed uplink frequency spectrum is not overlapped with the frequency range of the first downlink frequency spectrum, so that the UE supports the first uplink frequency spectrum transmission, the first downlink frequency spectrum transmission, the second appointed uplink frequency spectrum transmission and the second downlink frequency spectrum transmission, for example, the first carrier frequency band is N5 in the frequency band table, the second carrier frequency band is N8 in the frequency band table, the second appointed uplink frequency spectrum is UL-N8r, and after being adjusted by the first filtering device, the UE supports: N5-DL, DL-N5, UL-N8r and DL-N8;

(3) The frequency range of the first downlink frequency spectrum is adjusted through a third filtering device to generate a first appointed downlink frequency spectrum, the frequency range of the second uplink frequency spectrum is adjusted to generate a second appointed uplink frequency spectrum, no overlapping exists between the frequency range of the second appointed uplink frequency spectrum and the frequency range of the first appointed downlink frequency spectrum, so that the UE supports the first uplink frequency spectrum transmission, the first appointed downlink frequency spectrum transmission, the second appointed uplink frequency spectrum transmission and the second downlink frequency spectrum transmission, for example, the first carrier frequency band is N5 in the frequency band table, the second carrier frequency band is N8 in the frequency band table, the first appointed downlink frequency spectrum is DL-N5r, the second appointed uplink frequency spectrum is UL-N8r, and after being adjusted through the third filtering device, the UE supports: N5-DL, DL-N5r, UL-N8r and DL-N8;

optionally, in another embodiment, the implementation method may further include:

For example, in this embodiment, for the first downlink spectrum transmission and the second uplink spectrum transmission with spectrum overlapping, a mode that is not supported is adopted to avoid the problem of receiving and transmitting interference, for example, the first carrier frequency band is N5 in the frequency band table, the second carrier frequency band is N8 in the frequency band table, and the UE reports support based on its own configuration: (3) N5-D and DL-N8;

Through the method, the implementation mode met by the UE is determined, and the reporting of the capability indication information is carried out according to the implementation mode, so that the base station sends the corresponding carrier signal based on the capability indication information reported by the UE, and the problem of receiving and transmitting interference between the designated carrier frequency bands with overlapped frequency spectrums is avoided.
