As shown in fig. 2, an embodiment of the present disclosure provides an information processing method, wherein the method is performed by a terminal, and the method may include:

s1110: and sending terminal capability information according to the terminal capability of the terminal operating in the FDD mode, wherein the FDD mode comprises the following steps: FD-FDD mode and/or HD-FDD mode.

FDD mode refers to: the uplink transmission and the downlink reception of the terminal are terminal operation modes respectively set on different frequency bands. The frequency band used for uplink transmission is an uplink sub-band; the frequency band used for downlink reception is a downlink subband.

The FDD mode also includes: HD-FDD mode and FD-FDD mode.

HD-FDD mode refers to: the terminal operates an uplink sub-band or a downlink sub-band at one time.

FD-FDD mode refers to: the terminal may operate in both the uplink sub-band and the downlink sub-band at one time, i.e., perform uplink transmission and downlink reception at the same time.

And the terminal capability information indicates that the terminal supports the FD-FDD mode and/or the HD-FDD mode. For example, the terminal capability information is applicable to at least hardware capabilities having FD-FDD mode and HD-FDD mode. Such a hybrid (hybrid) FDD mode terminal supports both FD-FDD mode and HD-FDD mode on hardware.

The FDD mode terminal may be: capability default (reduced capability, redCap) terminals and/or conventional terminals other than RedCap terminals. The terminal may be a terminal supporting both FD-FDD mode and HD-FDD mode, and the terminal supporting both FD-FDD mode and HD-FDD mode may be: hybrid (hybrid) FDD mode terminals are supported.

As shown in fig. 3, the hybrid FDD mode terminal may include an antenna, an antenna-connected duplexer, and a switch connected in parallel with the duplexer. As shown in fig. 3, one side of the duplexer has two terminals, an uplink transmission terminal and a downlink reception terminal; the other side of the diplexer has a common terminal that is connected to the RF structure to transmit upstream transmissions to the RF structure and to receive downstream transmissions from the RF structure.

When the switch is closed, the switch is connected with an uplink transmitting terminal of the duplexer or a downlink receiving terminal of the duplexer, the impedance of a branch circuit where the switch is positioned is smaller than that of the duplexer, the branch circuit where the switch is positioned enters a switch state, and the duplexer is in a bypass non-working state.

When the switch is disconnected, the switch is not connected with an uplink transmitting terminal of the duplexer or a downlink receiving terminal of the duplexer, so that a branch where the switch is positioned is not conducted, and the duplexer is in an operating state.

By transmitting the terminal capability information, the base station can know whether the current terminal supports the FD-FDD mode alone, the HD-FDD mode alone, or both the FD-FDD mode and the HD-FDD mode.

If the terminal supports both the FD-FDD mode and the HD-FDD mode, the terminal operates in the FD-FDD mode and the HD-FDD mode and has the following characteristics:

for example, the maximum uplink transmit power of a terminal operating in HD-FDD mode may be greater than the maximum uplink transmit power of a terminal operating in FD-FDD mode;

for another example, the anti-interference capability of the terminal operating in the HD-FDD mode is higher than the uplink maximum transmit power of the terminal operating in the FD-FDD mode;

for another example, the total transmission bandwidth of a terminal operating in FD-FDD mode is greater than the total transmission bandwidth of a terminal operating in HD-FDD mode.

Of course, the above examples of terminal characteristics of the terminal operating in the FD-FDD mode and the HD-FDD mode are merely examples, and the specific implementation is not limited to the above examples.

As shown in fig. 4, an embodiment of the present disclosure provides an information processing method, wherein the method is performed by a terminal, and the method includes:

s1210: and transmitting terminal capability information according to the frequency division multiplexing mode currently supported by the terminal in response to the terminal having terminal capability operating in the FD-FDD mode and the HD-FDD mode, wherein the terminal capability information indicates that the terminal supports operating in the HD-FDD mode and/or the FD-FDD mode.

The terminal can be in the mixed FDD mode, and the terminal can determine whether the currently available FDD mode is the HD-FDD mode or the FD-FDD mode according to the current specific requirements. The terminal capability information indicates the FDD mode that the terminal is currently suitable for use, so that the subsequent base station can perform resource scheduling and/or communication control according to the FDD mode that the terminal is currently suitable for use.

If the HD-FDD mode indicated by the terminal capability information and/or the FD-FDD mode is determined according to the FDD mode actually suitable for the current terminal, the problem that the communication quality is not good enough due to the fact that the base station directly selects the FDD mode unsuitable for the current terminal according to the hardware capability of the terminal can be reduced, and the communication quality is improved.

In some embodiments, the terminal capability information is configured to support operation in the HD-FDD mode and/or the FD-FDD mode according to an indication of a frequency band granularity.

The spectral resources are divided into a plurality of frequency bands, e.g., in some cases, the spectral resources may be divided into n1 to n80 frequency bands. The terminal is currently operating on different frequency bands, and the guard interval between the uplink and downlink sub-bands on the different frequency bands may be different. The carrier transmission attenuation in the air is different for different frequency bands due to the different carrier frequencies.

Thus, in some cases, a terminal in hybrid FDD mode may be more suitable to operate in HD-FDD mode, or in FD-FDD mode, or both.

The base station can determine the FDD mode used by the terminal during operation according to the frequency band configured for the terminal.

In some embodiments, the terminal capability information is configured to indicate, in an enumerated manner, that the terminal supports operating in the HD-FDD mode and/or the FD-FDD mode.

For example, the terminal capability information may indicate in an enumerated manner the following three cases:

Case 1: the terminal is independently supported to work in an HD-FDD mode at present;

case 2: support alone to operate in FD-FDD mode;

case 3: the terminal supports operation in both HD-FDD and FD-FD modes.

In some embodiments, the terminal capability information includes at least one of:

a first IE indicating whether the terminal is currently supported to operate in the HD-FDD mode;

a second IE indicating whether the terminal currently supports operation in the FD-FDD mode;

a third IE indicating whether the terminal supports operation in both the HD-FDD mode and the FD-FDD mode;

and a fourth IE indicating that the terminal supports the HD-FDD mode alone or simultaneously operates in the HD-FDD mode and the FD-FDD mode.

Illustratively, any one of the first to fourth IEs may include: 1 or more bits. The different bit values of the bits of any one of the first IE to the fourth IE are specifically used to indicate the FDD mode currently supported by the terminal.

The embodiment of the disclosure provides an information processing method, wherein the method is executed by a terminal and comprises the following steps:

and transmitting terminal capability information containing a first IE according to a frequency division multiplexing mode currently supported by the terminal in response to the terminal having terminal capability operating in an FD-FDD mode and an HD-FDD mode, wherein the first IE indicates whether the terminal currently supports operating in the HD-FDD mode.

In one embodiment, if the terminal capability information includes an IE indicating that the terminal is currently suitable for operating in the FDD mode, the terminal capability information sent by the terminal does not include the first IE, if the terminal is not currently supported to operate in the HD-FDD mode. At this time, the base station may consider that the terminal may currently operate in FD-FDD mode. If the terminal currently supports to operate in the HD-FDD mode, the terminal sends terminal capability information including a first IE indicating that the terminal currently supports to operate in the HD-FDD mode, and the base station considers that the terminal supports to operate in the HD-FDD mode.

In another embodiment, if the IE included in the terminal capability information indicating that the terminal is currently suitable for operating in the FDD mode only includes the first IE, and if the terminal is not currently supported to operate in the HD-FDD mode, the terminal capability information sent by the terminal includes the first IE, and the first IE indicates that the terminal is not currently supported to operate in the HD-FDD mode, at this time, the base station may consider that the terminal is currently capable of operating in the FD-FDD mode. If the terminal currently supports to operate in the HD-FDD mode, the terminal sends terminal capability information including a first IE indicating that the terminal currently supports to operate in the HD-FDD mode, and the base station considers that the terminal supports to operate in the HD-FDD mode.

and transmitting terminal capability information containing a second IE according to the frequency division multiplexing mode currently supported by the terminal in response to the terminal having the terminal capability of operating in the FD-FDD mode and the HD-FDD mode, wherein the second IE indicates whether the terminal currently supports operating in the FD-FDD mode.

The second IE may indicate that the terminal is currently supported to operate in FD-FDD mode or not supported to operate in FD-FDD mode.

transmitting terminal capability information including a first IE and a second IE according to a frequency division multiplexing mode currently supported by the terminal in response to the terminal having terminal capability operating in an FD-FDD mode and an HD-FDD mode; a first IE indicates whether the terminal supports the operation in the HD-FDD mode at present; a second IE indicating whether the terminal currently supports supporting operation in FD-FDD mode. The base station needs to jointly determine that the terminal is currently and independently supported to work in an FD-FDD mode or is currently and independently supported to work in an HD-FDD mode by combining a first IE and a second IE; alternatively, operation in both FD-FDD mode and HD-FDD mode is currently supported.

and transmitting terminal capability information containing a fourth IE according to the frequency division multiplexing mode currently supported by the terminal in response to the terminal having terminal capability operating in the FD-FDD mode and the HD-FDD mode. And a fourth IE indicating that the terminal supports the HD-FDD mode alone or simultaneously operates in the HD-FDD mode and the FD-FDD mode.

and transmitting terminal capability information comprising a first IE and a third IE according to a frequency division multiplexing mode currently supported by the terminal in response to the terminal having terminal capability operating in the FD-FDD mode and the HD-FDD mode. A first IE indicating whether the terminal is currently supported to operate in the HD-FDD mode; and a third IE indicating whether the terminal supports operation in the HD-FDD mode and the FD-FDD mode simultaneously. After receiving the first IE and the third IE, the base station ignores the first IE, and determines that the terminal is currently supported to operate in both the FD-FDD mode and the HD-FDD mode according to the third IE alone.

In another embodiment, the transmitting, in response to the terminal having terminal capabilities operating in FD-FDD mode and HD-FDD mode, terminal capability information including a first IE and a third IE according to a frequency division multiplexing mode currently supported by the terminal, includes:

transmitting terminal capability information including a first IE and a third IE in response to the terminal having terminal capabilities operating in FD-FDD mode and HD-FDD mode and the terminal currently supporting both HD-FDD mode and FD-FDD mode; the third IE supports the terminal currently supporting both the HD-FDD mode and the FD-FDD mode.

In addition, if the terminal capability information corresponds to the first IE and the third IE, the terminal capability information including the first IE is sent according to whether the terminal currently supports the HD-FDD mode or not in response to the terminal having the terminal capability operating in the FD-FDD mode and the HD-FDD mode and the terminal currently does not support both the HD-FDD mode and the FD-FDD mode.

As shown in fig. 5, an embodiment of the present disclosure provides an information processing method, wherein the method is performed by a terminal, and the method includes:

s1310: determining a frequency division multiplexing mode currently supported by the operation of the terminal according to the condition information of the terminal in response to the terminal having the terminal capability of operating in the FD-FDD mode and the HD-FDD mode;

S1320: and transmitting terminal capability information according to the frequency division multiplexing mode currently supported by the terminal, wherein the terminal capability information indicates that the terminal supports working in the HD-FDD mode and/or the FD-FDD mode.

The status information of the terminal may include various information indicating the current status of the terminal, and may include at least one of:

the data transmission requirement of the terminal;

an interval between an uplink sub-band and a downlink sub-band of an operating band of the terminal;

the maximum transmitting power of the terminal operating in the FD-FDD mode;

the channel quality corresponding to the current working wave beam of the terminal;

the current data transmission success rate of the terminal;

the number of data retransmissions at the terminal.

Data transmission herein includes, but is not limited to: uplink data transmission and/or downlink data transmission.

In some embodiments, the determining, according to the status information of the terminal, the frequency division multiplexing mode currently supported by the operation of the terminal includes at least one of the following:

determining a frequency division multiplexing mode currently supported by the terminal according to a current working frequency band of the terminal and a bandwidth interval between an uplink sub-band and a downlink sub-band of the current working frequency band;

Determining a frequency division multiplexing mode currently supported by the terminal according to a current working frequency band of the terminal and interference condition information between an uplink sub-band and a downlink sub-band of the current working frequency band;

and determining the frequency division multiplexing mode currently supported by the terminal according to the current position of the terminal.

For example, if the bandwidth interval (i.e., the guard interval) between the uplink sub-band and the downlink sub-band is used to measure the mutual interference between the uplink signal and the downlink signal in the FD-FDD mode of operation of the terminal.

Illustratively, when the bandwidth interval between the uplink and downlink sub-bands is greater than or equal to the interval threshold, it may be determined that the terminal may currently operate in FD-FDD mode. When the bandwidth interval between the uplink sub-band and the downlink sub-band is smaller than the interval threshold, it may be determined that the terminal is currently operating in HD-FDD mode.

In some embodiments, the terminal and/or the base station may measure the actual interference value between the uplink sub-band and the downlink when the terminal is operating in FD-FDD mode.

Illustratively, the interference between the uplink and downlink signals may be directly or indirectly embodied using a signal-to-interference plus noise ratio (Signal to Interference plus Noise Ratio, SINR), a received signal strength (Received Signal Strength Indication, RSSI), a reference signal received power (Reference Signal Receiving Power, RSRP), and a reference signal received power (Reference Signal Received Power, RSRQ) when the terminal operates in FD-FDD mode.

If SINR, RSSI, RSRP or RSRQ is greater than the corresponding threshold, the interference between the uplink signal and the downlink signal is considered to be small, and the terminal can operate in FD-FDD mode; otherwise the terminal may be considered to be currently operating in HD-FDD mode.

In still other embodiments, the location of the terminal herein may include: the current cell position of the terminal is different, the distance between the terminal and the base station is different when the terminal is at different cell positions, and the shielding condition on the transmission channel between the terminal and the base station is different.

In some embodiments, the determining the frequency division multiplexing mode currently supported by the terminal according to the current location of the terminal includes at least one of the following:

when the terminal is currently positioned in the center of a cell, determining the FD-HDD mode currently supported by the terminal;

and when the terminal is currently positioned at the cell edge, determining the HD-HDD mode currently supported by the terminal.

For example, if the terminal is in the center of the cell, the terminal is closer to the base station, and the uplink transmission power required by the terminal is smaller, so that the terminal can work in the FD-FDD mode with smaller uplink transmission power. If the terminal is at the cell edge, the distance between the terminal and the base station is far, and in order to ensure the uplink transmission quality, the terminal can operate in HD-FDD mode.

For example, the cell center and cell edge may be determined based on a distance threshold. The distance threshold may be: the product of the cell radius and a preset value. The preset value may be a value between 0 and 1.

The terminal related to the embodiment of the disclosure may be: any type of terminal, for example, the terminal may be a terminal supporting carrier aggregation, and the terminal may be a terminal supporting dual connectivity.

As shown in fig. 6, an embodiment of the present disclosure provides an information processing method, wherein the method is performed by a base station, and the method includes:

s2110: and receiving terminal capability information.

In one embodiment, the terminal capability information indicates that the terminal supports terminal capabilities operating in FD-FDD mode and/or in HD-FDD mode, and such terminal capabilities refer to whether the terminal is structurally supported.

In another embodiment, the terminal capability information indicates a frequency division multiplexing mode in which the terminal is currently operating, and in this case, the terminal may be a hybrid FDD mode terminal having terminal capabilities operating in the FD-FDD mode and the HD-FDD mode.

After receiving the terminal capability information, the base station determines the current supported FDD mode of the mixed FDD mode terminal according to the terminal capability information.

If the base station schedules the FDD mode of the terminal, the base station can instruct the terminal to work in the current appropriate FDD mode according to the network signaling sent by the terminal capability information.

In an embodiment, the terminal capability information is configured to support the terminal to operate in the HD-FDD mode and/or the FD-FDD mode according to an indication of a frequency band granularity.

The terminal capability information indicates whether the terminal supports operation in HD-FDD mode, FD-FDD mode, or both HD-FDD mode and FD-FDD mode according to the band granularity. Thus, the base station can send network signaling indicating the current working FDD mode of the terminal according to the current working frequency band of the terminal.

case 2: support alone to operate in FD-FDD mode;

case 3: the terminal supports operation in both HD-FDD and FD-FD modes.

The above is merely an illustration of the FDD mode currently supported by the terminal in the terminal capability information, and the implementation is not limited to the above illustration.

An embodiment of the present disclosure provides an information processing method, wherein the method is performed by a base station, and the method includes:

and receiving terminal capability information.

And when the terminal capability information comprises the first IE, determining whether the terminal is currently supported to work in the HD-FDD mode according to the first IE.

And receiving terminal capability information.

When the terminal capability information independently includes a fourth IE, determining whether the terminal supports the HD-FDD mode at the present time or supports both the HD-FDD mode and the FD-FDD mode according to the fourth IE.

and receiving terminal capability information.

When the terminal capability information contains the first IE and the second IE at the same time, determining that the terminal is currently independently supported to work in the HD-FDD mode, the terminal is currently independently supported to work in the FD-FDD mode or the terminal is simultaneously supported to work in the HD-FDD mode and the FD-FDD mode according to the first IE and the second IE.

At this time, the base station needs to determine the FDD mode currently supported by the terminal in combination with two IEs.

receiving terminal capability information;

and when the terminal capability information receives the first IE and the third IE simultaneously, ignoring the first IE and determining that the terminal is currently supported to work in the HD-FDD mode and the FD-FDD mode simultaneously according to the third IE.

receiving terminal capability information;

and in the case that the terminal capability information independently comprises the first IE, the terminal capability information defaults the first IE, and determines that the terminal supports to work in the FD-FDD mode.

receiving terminal capability information;

and under the condition that the terminal capability information can simultaneously contain the first IE and the third IE, the received terminal capability information independently contains the first IE, and the terminal is determined to simultaneously support the operation in the HD-FDD mode and the FD-FDD mode according to the first IE.

For a high-power terminal or a terminal working under a large bandwidth, on some FDD frequency bands, if the terminal works in a full duplex FD-FDD mode, the uplink signal will have serious interference to the downlink signal, which results in a significant deterioration of the receiving capability of the terminal receiver, but if the terminal simply adopts a half duplex HD-FDD mode, the spectrum use efficiency will be reduced.

In some FDD bands, the guard interval between the uplink and downlink subbands is small, which results in high interference of the uplink signal to the downlink signal, especially when the transmit power is high or in a large bandwidth. In order to avoid the interference of the uplink signal to the downlink signal, the terminal can make the terminal work in the HD-FDD mode under the condition of higher transmitting power, i.e. the uplink and downlink of the FDD are transmitted and received by time division and frequency division.

When the terminal is located at the center of the cell, the terminal can be operated in FD-FDD mode with a lower required transmit power.

And the terminal may report the capability of the terminal to operate in FDD mode in a single frequency band (per band) through a new information element (Information Element, IE) such as Supporting Duplex Mode-rxx signaling.

The terminal capability can also be used in a multi-carrier system, and the terminal can report the terminal capability of the FDD mode of the terminal with the frequency band granularity (per band per band combination).

The manner in which the terminal reports the supported FDD mode specifically includes, but is not limited to:

Supporting Duplex Mode-rxx ENUMERATED{half,full,both}；

or alternatively

Supporting Duplex Mode-rxx ENUMERATED{half,both}。

Half here represents HD-FDD mode; full stands for FD-FDD mode. Both stands for HD-FDD mode and FD-FDD mode.

When the terminal reports half through Supporting Duplex Mode-rxx signaling per band, the terminal only supports the HD-FDD mode on the frequency band.

When the terminal reports full through Supporting Duplex Mode-rxx signaling per band, or this signaling by default represents the FD-FDD mode that the terminal supports full duplex on that frequency band.

When the terminal reports the both through the supporting duplex mode-rxx signaling per band, it is represented that the terminal supports both FD-FDD mode and HD-FDD mode on the frequency band. How the FDD mode currently used by the terminal is configured may depend on the network scheduling.

Fig. 7 is a signaling diagram illustrating a terminal sending terminal capability information to a base station.
