As shown in fig. 2, an embodiment of the present disclosure provides an information processing method, which is performed by a terminal, the method including:

s2110: responsive to the terminal supporting FD-FDD mode and HD-FDD mode, determining that the terminal is operating in either the FD-FDD mode or HD-FDD mode.

The terminal may be: capability default (reduced capability, 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 FDD mode is supported.

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

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

HD-FDD (half duplex) mode refers to: the uplink transmission and the downlink reception in the FDD band are performed by time division and frequency division.

FD-FDD (full duplex) mode refers to: the uplink transmission and the downlink reception of the terminal on the FDD frequency band may be performed simultaneously.

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. 3, the 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.

In the embodiment of the present disclosure, since the terminal supports both FD-FDD mode and HD-FDD mode, it is necessary to determine whether the current selection is currently operating in FD-FDD mode or HD-FDD mode before entering the operating state.

The terminal determines that the terminal works in the FD-FDD mode or the HD-FDD mode according to the current network condition and/or the own transmission requirement, so that the FDD mode of the terminal is standardized, and the phenomenon of power consumption waste or insufficient communication quality caused by randomly selecting one FDD mode by the terminal is ensured.

Notably, are: determining that the terminal is operating in HD-FDD mode or FD-FDD mode herein may include: an FDD mode used by the terminal in an initial access phase, or an FDD mode used after the initial access phase.

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

s2210: responsive to the terminal supporting FD-FDD mode and HD-FDD mode, determining that the terminal is operating in the FD-FDD mode according to a default configuration.

Illustratively, S2210 may include at least one of: responsive to the terminal supporting FD-FDD mode and HD-FDD mode, determining that the terminal is operating in the FD-FDD mode according to a default configuration after the terminal is registered with the network;

and in response to the terminal supporting the FD-FDD mode and the HD-FDD mode, when the operation mode indicated by the network signaling is not received, determining that the terminal works in the FD-FDD mode according to the default configuration.

The default configuration may be configuration information pre-configured within the terminal or a configuration received after the terminal first accesses the network.

The registration of the terminal with the network may include, but is not limited to, at least one of:

initial access after the terminal is started;

the terminal is accessed after exiting the flight mode;

the terminal enters the access of the network coverage area from the non-network coverage area.

In some embodiments, if the HD-FDD mode or FD-FDD mode of the terminal is determined before the terminal operates in the HD-FDD mode or FD-FDD mode according to network signaling, network conditions, and/or other non-default configuration reference factors such as transmission requirements of the terminal itself, the terminal may use the HD-FDD mode or FD-FDD mode determined according to the default configuration.

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

s2310: and in response to the terminal supporting the FD-FDD mode and the HD-FDD mode, determining that the terminal works in the FD-FDD mode or the HD-FDD mode according to the access condition information of the terminal.

If the terminal supports the FD-FDD mode and the HD-FDD mode after the terminal is connected to the network for a period of time, the terminal can be comprehensively considered to operate in the FD-FDD mode or the HD-FDD mode according to the connection status of the terminal during the period of time when the terminal is connected to the network.

If the terminal fails to be repeatedly accessed, the current terminal needs higher transmitting power to compete for the access opportunity, so that the terminal can work in the HD-FDD mode, and the terminal can have higher transmitting power to compete for the access opportunity, thereby realizing network access. Of course, this is merely an example, and the embodiments are not limited thereto.

In some embodiments, the S2310 includes at least one of:

responding to the terminal supporting an FD-FDD mode and an HD-FDD mode, and determining that the terminal works in the HD-FDD mode when the access failure times of the terminal in a first duration are equal to or greater than a first time threshold;

Responding to the terminal supporting an FD-FDD mode and an HD-FDD mode, and determining that the terminal works in the FD-FDD mode when the access failure times of the terminal in a first duration are smaller than a first time threshold;

determining that the terminal is operating in the HD-FDD mode when the number of consecutive access failures of the terminal is equal to or greater than a second threshold in response to the terminal supporting both FD-FDD mode and HD-FDD mode

And in response to the terminal supporting the FD-FDD mode and the HD-FDD mode, determining that the terminal works in the FD-FDD mode when the continuous number of access failures of the terminal is smaller than a second number threshold.

The first duration may be any duration, for example, the first duration may be a duration negotiated between the terminal and the base station, or a duration agreed by a protocol. The first duration may comprise a duration between one or more random access occasions. Illustratively, the first duration may include: one or more radio frames.

The first order number threshold may be a value of 2, 3, 4, 5, or 6, etc. Of course, the specific range of values may be determined based on historical access success rates and/or experimental values, for example only.

If the first time length is set, the terminal can start the timer according to the first time length, and when the access failure frequency of the terminal is equal to or greater than the first time threshold value when the timer is overtime, the terminal can be considered to be more suitable for working in the HD-FDD mode.

In some embodiments, the second time threshold may be equal to or unequal from the first time threshold.

If the terminal is determined to be currently operated in the HD-FDD mode or the FD-FDD mode according to the continuous number of access failures, a timer is not required to be started, and only the continuous number of access failures is required to be paid attention to.

The above is merely a specific example of how to determine the FDD mode of the terminal according to the access status information, and the implementation is not limited to the above example.

The reference signals include, but are not limited to, synchronization Signal Blocks (SSBs), channel state information reference signals, and/or demodulation reference signals, among others.

If the network signal quality is good, the terminal may preferably select the terminal to operate in the FD-FDD mode in order to obtain a larger transmission bandwidth or to enable synchronous execution of uplink transmission and downlink reception, otherwise the terminal may determine to operate in the HD-FDD mode.

In some embodiments, the S2410 may include at least one of:

The second time period may be any time period. For example, the second duration may be a duration negotiated between the terminal and the base station, or a duration agreed by the protocol. The second duration may comprise a duration between one or more random access occasions. Illustratively, the second time period may include: one or more radio frames.

NACK is generally used to indicate data transmission failure, and if the number of transmission failures is large, it can be determined that the terminal is more suitable to operate in FD-FDD mode.

In some embodiments, the number of NACKs that the terminal receives and transmits here may include:

the number of times the terminal receives NACK;

the number of NACKs sent by the terminal;

Similarly, the number of retransmissions is an index reflecting the transmission status, and is based on the retransmission of the hybrid automatic repeat request (Hybrid Automatic Repeat reQuest, HARQ) feedback, or not based on HARQ, but delayed retransmission. For example, if the delay does not receive an indication of successful reception, the retransmission is automatic.

The embodiments of the present disclosure mainly address the case where a terminal is operating in hybrid FDD mode, if it is accessing the network and how the network manages such terminals.

The FDD mode selection of the terminal at the initial access phase may be as follows:

firstly, the terminal works in an FD-FDD mode, and when the access failure times of the FD-FDD mode reach the preset times, the terminal can be switched to an HD-FDD mode;

the third mode is that the network can preset a threshold of RSRP, when the measured value of RSRP of the terminal is greater than the threshold, the terminal works in FD-FDD mode, and when the measured value is less than the threshold, the terminal can work in HD-FDD mode.
