As shown in Figure 2, an embodiment of the present disclosure provides an information processing method, which is executed by a terminal. The method may include:

S1110: Send terminal capability information according to the terminal capability of the terminal working in FDD mode, where the FDD mode includes: FD-FDD mode and/or HD-FDD mode.

The FDD mode refers to the terminal operating mode in which the terminal's uplink transmission and downlink reception are respectively set on different frequency bands. The frequency band used for uplink transmission is the uplink sub-band; the frequency band used for downlink reception is the downlink sub-band.

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

The HD-FDD mode means that the terminal operates the uplink subband or the downlink subband at one time.

The FD-FDD mode means that the terminal can work in the uplink subband and downlink subband at the same time, that is, perform uplink transmission and downlink reception at the same time.

The terminal capability information indicates that the terminal supports FD-FDD mode and/or HD-FDD mode. For example, the terminal capability information can be used at least for hardware capabilities with FD-FDD mode and HD-FDD mode. This kind of hybrid FDD mode terminal supports both FD-FDD mode and HD-FDD mode in hardware.

The FDD mode terminal may be: a reduced capability (RedCap) terminal and/or a conventional terminal other than a RedCap terminal. The terminal may be a terminal that supports both FD-FDD mode and HD-FDD mode. The terminal that supports both FD-FDD mode and HD-FDD mode may be a terminal that supports hybrid FDD mode.

As shown in Figure 3, the hybrid FDD mode terminal may include an antenna, a duplexer connected to the antenna, and a switch, and the switch is connected in parallel with the duplexer. As shown in Figure 3, one side of the duplexer has two terminals, an uplink transmitting terminal and a downlink receiving terminal; the other side of the duplexer has a common terminal, which is connected to the RF structure and transmits the uplink Transmitted to and received downstream from the RF structure.

When the switch is closed, the switch is connected to the uplink transmitting terminal of the duplexer or connected to the downlink receiving terminal of the duplexer. The impedance of the branch where the switch is located is smaller than the impedance of the duplexer, and the branch where the switch is located enters the switching state, and The duplexer is in a bypassed, inactive state.

When the switch is turned off, the switch is neither connected to the uplink transmitting terminal of the duplexer nor connected to the downlink receiving terminal of the duplexer. In this case, the branch where the switch is located will not be conductive, so the duplexer is in working condition.

By sending the above terminal capability information, the base station can know whether the current terminal supports FD-FDD mode alone, HD-FDD mode alone, or supports FD-FDD mode and HD-FDD mode at the same time.

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

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

For another example, the anti-interference ability of a terminal operating in HD-FDD mode is stronger than the maximum uplink transmit power of the terminal operating in FD-FDD mode;

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

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

As shown in Figure 4, an embodiment of the present disclosure provides an information processing method, which is executed by a terminal. The method includes:

S1210: In response to the terminal having the terminal capability of operating in FD-FDD mode and HD-FDD mode, send terminal capability information according to the frequency division multiplexing mode currently supported by the terminal, where the terminal capability information indicates The terminal supports working in the HD-FDD mode and/or the FD-FDD mode.

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

If the HD-FDD mode and/or the FD-FDD mode indicated by the terminal capability information is determined based on the FDD mode actually suitable for the current terminal, it can be reduced that the base station directly selects an FDD mode that is not suitable for the current use of the terminal based on the hardware capabilities of the terminal. solve the problem of insufficient communication quality and improve the communication quality.

In some embodiments, the terminal capability information is used to indicate that the terminal supports working in the HD-FDD mode and/or the FD-FDD mode according to frequency band granularity instructions.

Spectrum resources are divided into multiple frequency bands. For example, in some cases, spectrum resources can be divided into frequency bands n1 to n80. The terminal currently operates on different frequency bands, and the guard intervals between the uplink subbands and downlink subbands on different frequency bands may be different. Due to different carrier frequencies in different frequency bands, carrier transmission attenuation in the air is different.

Therefore, in some cases, a terminal in mixed FDD mode may be more suitable to operate in HD-FDD mode, or may be more suitable to operate in FD-FDD mode, or may be able to operate in both HD-FDD mode and FD-FDD mode.

Here, the terminal is instructed to support working in HD-FDD mode and/or FD-FDD mode according to the frequency band granularity. Then the base station can determine the FDD mode used by the terminal according to the frequency band configured for the terminal.

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

For example, terminal capability information can indicate the following three situations in an enumeration manner:

Case 1: The terminal currently supports working in HD-FDD mode alone;

Case 2: Support working in FD-FDD mode alone;

Case 3: The terminal supports working in HD-FDD mode and FD-FD mode at the same time.

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

The first IE indicates whether the terminal currently supports working in the HD-FDD mode;

The second IE indicates whether the terminal currently supports working in the FD-FDD mode;

The third IE indicates whether the terminal supports working in the HD-FDD mode and the FD-FDD mode at the same time;

The fourth IE indicates that the terminal supports the HD-FDD mode alone, or supports working in the HD-FDD mode and the FD-FDD mode at the same time.

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

Embodiments of the present disclosure provide an information processing method, which is executed by a terminal. The method includes:

In response to the terminal having the terminal capability of operating in the FD-FDD mode and the HD-FDD mode, according to the frequency division multiplexing mode currently supported by the terminal, terminal capability information including the first IE is sent, where the first IE, Indicates whether the terminal currently supports working in the HD-FDD mode.

In one embodiment, if the terminal capability information contains an IE indicating the FDD mode in which the terminal is currently suitable for operation, it only contains the first IE. If the terminal currently does not support working in the HD-FDD mode, the terminal capability information sent by the terminal does not include the third IE. 1 IE. At this time, the base station will consider that the terminal can currently work in FD-FDD mode. If the terminal currently supports working in the HD-FDD mode, and the terminal sends terminal capability information including the first IE, the first IE indicates that the terminal currently supports working in the HD-FDD mode, then the base station considers that the terminal supports working in the HD-FDD mode. .

In another embodiment, if the terminal capability information contains an IE indicating the FDD mode in which the terminal is currently suitable for operation, only the first IE is included. If the terminal currently does not support working in the HD-FDD mode, the terminal capability information sent by the terminal includes the third IE. One IE, and the first IE indicates that the terminal currently does not support working in the HD-FDD mode. At this time, the base station will consider that the terminal can currently work in the FD-FDD mode. If the terminal currently supports working in the HD-FDD mode, and the terminal sends terminal capability information including the first IE, the first IE indicates that the terminal currently supports working in the HD-FDD mode, then the base station considers that the terminal supports working in the HD-FDD mode. .

In response to the terminal having the terminal capability of operating in the FD-FDD mode and the HD-FDD mode, according to the frequency division multiplexing mode currently supported by the terminal, terminal capability information including the second IE is sent, where the second IE, Indicates whether the terminal currently supports working in the FD-FDD mode.

The second IE may indicate that the terminal currently supports working in the FD-FDD mode or does not support working in the FD-FDD mode.

In response to the terminal having the terminal capability of operating in the FD-FDD mode and the HD-FDD mode, sending terminal capability information including the first IE and the second IE according to the frequency division multiplexing mode currently supported by the terminal; and One IE indicates whether the terminal currently supports working in the HD-FDD mode; the second IE indicates whether the terminal currently supports working in the FD-FDD mode. The base station needs to combine the first IE and the second IE to jointly determine that the terminal currently supports working in FD-FDD mode alone, or currently supports working in HD-FDD mode alone; or, currently supports working in FD-FDD mode and HD-FDD mode at the same time. .

In response to the terminal having the terminal capability of operating in the FD-FDD mode and the HD-FDD mode, terminal capability information including the fourth IE is sent according to the frequency division multiplexing mode currently supported by the terminal. The fourth IE indicates that the terminal supports the HD-FDD mode alone, or supports working in the HD-FDD mode and the FD-FDD mode at the same time.

In response to the terminal having the terminal capability of operating in the FD-FDD mode and the HD-FDD mode, terminal capability information including the first IE and the third IE is sent according to the frequency division multiplexing mode currently supported by the terminal. The first IE indicates whether the terminal currently supports working in the HD-FDD mode; the third IE indicates whether the terminal supports working in the HD-FDD mode and the FD-FDD mode at the same time. After receiving the first IE and the third IE, the base station ignores the first IE and determines based on the third IE alone that the terminal currently supports working in both the FD-FDD mode and the HD-FDD mode.

In another embodiment, in response to the terminal having the terminal capability of operating in FD-FDD mode and HD-FDD mode, according to the frequency division multiplexing mode currently supported by the terminal, sending the first IE and the first IE according to the frequency division multiplexing mode currently supported by the terminal. Three IE terminal capability information, including:

In response to the terminal having the terminal capability of operating in the FD-FDD mode and the HD-FDD mode, and the terminal currently supports both the HD-FDD mode and the FD-FDD mode, sending terminal capability information including the first IE and the third IE; The third IE supporting terminal currently supports both HD-FDD mode and FD-FDD mode.

In addition, if the terminal capability information corresponds to the first IE and the third IE, the response is that the terminal has the terminal capability to operate in the FD-FDD mode and the HD-FDD mode, and the terminal does not currently support the HD-FDD mode at the same time. and FD-FDD mode, sending terminal capability information including the first IE according to whether the terminal currently supports the HD-FDD mode.

As shown in Figure 5, an embodiment of the present disclosure provides an information processing method, which is executed by a terminal. The method includes:

S1310: In response to the terminal having the terminal capability of operating in FD-FDD mode and HD-FDD mode, determine the frequency division multiplexing mode currently supported by the terminal according to the status information of the terminal;

S1320: Send terminal capability information according to the frequency division multiplexing mode currently supported by the terminal, where 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. For example, the status information of the terminal may include at least one of the following:

Terminal data transmission requirements;

The interval between the uplink sub-band and the downlink sub-band of the terminal’s operating frequency band;

The maximum transmit power of the terminal working in FD-FDD mode;

The channel quality corresponding to the terminal’s current working beam;

The current data transmission success rate of the terminal;

The number of data retransmissions by the terminal.

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

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

Determine the frequency division multiplexing mode currently supported by the terminal according to the current operating frequency band of the terminal and the bandwidth interval between the uplink subband and downlink subband of the current operating frequency band;

Determine the frequency division multiplexing mode currently supported by the terminal according to the current operating frequency band of the terminal and the interference status information between the uplink subband and downlink subband of the current operating frequency band;

According to the current location of the terminal, the frequency division multiplexing mode currently supported by the terminal is determined.

For example, the bandwidth interval (ie, guard interval) between the uplink subband and the downlink subband can be used to measure the mutual interference between the uplink signal and the downlink signal when the terminal operates in the FD-FDD mode.

For example, when the bandwidth interval between the uplink subband and the downlink subband is greater than or equal to the interval threshold, it may be determined that the terminal can currently operate in the FD-FDD mode. When the bandwidth interval between the uplink subband and the downlink subband is less than the interval threshold, it can be determined that the terminal is currently operating in HD-FDD mode.

In some embodiments, the terminal and/or the base station can measure the actual interference value between the uplink subband and the downlink when the terminal operates in the FD-FDD mode.

For example, the signal to interference plus noise ratio (SINR), the received signal strength (Received Signal Strength Indication, RSSI), and the reference signal received power (Reference Signal Receiving Power (RSRP) and Reference Signal Received Power (RSRQ) to directly or indirectly reflect the interference between the uplink signal and the downlink signal.

If SINR, RSSI, RSRP or RSRQ are all greater than the corresponding threshold, it is considered that the current interference between the uplink signal and the downlink signal is small, and the terminal can work in the FD-FDD mode; otherwise, the terminal can be considered to be suitable for working in the HD-FDD mode.

In some embodiments, the location of the terminal here may include: the current cell location of the terminal is different. If the terminal is in a different cell location, the distance from the base station is different, and the transmission channel between the terminal and the base station is The occlusion conditions are different.

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

When the terminal is currently located in the center of the cell, determine the FD-HDD mode currently supported by the terminal;

When the terminal is currently located at a cell edge, the HD-HDD mode currently supported by the terminal is determined.

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

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

The terminal involved in the embodiment of the present disclosure may be any type of terminal. For example, the terminal may be a terminal that supports carrier aggregation, or the terminal may be a terminal that supports dual connectivity.

As shown in Figure 6, an embodiment of the present disclosure provides an information processing method, which is executed by a base station. The method includes:

S2110: Receive terminal capability information.

In one embodiment, the terminal capability information indicates that the terminal supports the terminal capability of operating in the FD-FDD mode and/or the HD-FDD mode. This terminal capability refers to whether the terminal structure supports it.

In another embodiment, the terminal capability information indicates the frequency division multiplexing mode in which the terminal is currently operating. At this time, the terminal may be a hybrid FDD mode terminal, and the hybrid FDD mode terminal has the ability to operate in the FD-FDD mode. and terminal capabilities in the HD-FDD mode.

After receiving the terminal capability information, the base station determines the FDD mode currently supported by the hybrid FDD mode terminal based on the terminal capability information.

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

In one embodiment, the terminal capability information is used to indicate that the terminal supports working in the HD-FDD mode and/or the FD-FDD mode according to frequency band granularity instructions.

The terminal capability information indicates whether the terminal supports working in HD-FDD mode, FD-FDD mode, or both HD-FDD mode and FD-FDD mode according to frequency band granularity. In this way, the base station can send network signaling indicating the FDD mode in which the terminal is currently operating according to the current operating frequency band of the terminal.

Case 1: The terminal currently supports working in HD-FDD mode alone;

Case 2: Support working in FD-FDD mode alone;

The above are just examples for indicating the FDD mode currently supported by the terminal in the terminal capability information, and the specific implementation is not limited to the above examples.

Embodiments of the present disclosure provide an information processing method, which is executed by a base station. The method includes:

Receive terminal capability information.

When the terminal capability information includes the first IE, it is determined according to the first IE whether the terminal currently supports working in the HD-FDD mode.

Receive terminal capability information.

When the terminal capability information alone includes the fourth IE, it is determined according to the fourth IE whether the terminal currently supports the HD-FDD mode, or supports working in the HD-FDD mode and the FD mode at the same time. -FDD mode.

Receive terminal capability information.

When the terminal capability information includes both the first IE and the second IE, it is determined based on the first IE and the second IE that the terminal currently supports working in the HD-FDD mode alone, and the terminal currently supports Support working in the FD-FDD mode alone, or supporting working in the HD-FDD mode and the FD-FDD mode at the same time.

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

Receive terminal capability information;

When the terminal capability information receives the first IE and the third IE at the same time, ignore the first IE and determine based on the third IE that the terminal currently supports working in the HD-FDD mode and the Describe the FD-FDD mode.

Receive terminal capability information;

In the case where the terminal capability information alone contains the first IE, the terminal capability information defaults to the first IE to determine that the terminal supports working in the FD-FDD mode.

Receive terminal capability information;

In the case where the terminal capability information can contain both the first IE and the third IE, the received terminal capability information alone contains the first IE, and it is determined based on the first IE that the terminal currently supports both operations. in the HD-FDD mode and the FD-FDD mode.

For high-power terminals or terminals operating in large bandwidths, in some FDD frequency bands, if the terminal operates in full-duplex FD-FDD mode, the uplink signal interferes with the downlink signal seriously, causing the receiving capability of the terminal receiver to change. The difference is much worse, but if the terminal simply adopts the half-duplex HD-FDD mode, the spectrum usage efficiency will be reduced.

In some FDD frequency bands, because the guard interval between the uplink subband and the downlink subband is relatively small, the uplink signal interferes with the downlink signal greatly, especially when the transmit power is relatively high or the bandwidth is large. In order to avoid the interference of uplink signals on downlink signals, the terminal can operate in the HD-FDD mode when the transmit power is relatively high, that is, the uplink and downlink of FDD are transmitted and received in time and frequency division.

When the terminal is located in the center of the cell and the required transmit power of the terminal is low, the terminal can be made to work in the FD-FDD mode.

And the terminal can report the terminal's ability to operate in FDD mode according to a single frequency band (per band) through a new information element (IE), such as Supporting Duplex Mode-rxx signaling.

This terminal capability can also be used in multi-carrier systems. The terminal can report the terminal capability of the terminal in FDD mode at the frequency band granularity (per band per band combination).

The methods for terminals to report supported FDD modes include but are not limited to:

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

or

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

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

When the terminal reports half through Supporting Duplex Mode-rxx signaling per band, it indicates that the terminal only supports HD-FDD mode in this frequency band.

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

When the terminal reports both through SupportingDuplexMode-rxx signaling per band, it means that the terminal supports both FD-FDD mode and HD-FDD mode in this frequency band. How to configure the FDD mode currently used by the terminal may depend on network scheduling.
