The wireless communication system may include: several UEs 11 and several access devices 12.

Wherein, UE 11 may be a device that provides voice and/or data connectivity to users. The UE 11 can communicate with one or more core networks via a Radio Access Network (RAN). The UE 11 can be an Internet of Things UE, such as a sensor device, a mobile phone (or a "cellular" phone) and a device with The computer of the IoT UE may, for example, be a fixed, portable, pocket-sized, handheld, computer-built-in or vehicle-mounted device. For example, station (STA), subscriber unit (subscriber unit), subscriber station, mobile station (mobile station), mobile station (mobile), remote station (remote station), access point, remote UE ( remote terminal), access UE (access terminal), user terminal (user terminal), user agent (user agent), user equipment (user device), or user UE (user equipment, UE). Alternatively, UE 11 can also be a device for an unmanned aerial vehicle. Alternatively, the UE 11 may also be a vehicle-mounted device, for example, it may be a driving computer with a wireless communication function, or a wireless communication device connected to an external driving computer. Alternatively, the UE 11 can also be a roadside device, for example, it can be a street light, a signal light or other roadside equipment with wireless communication functions.

The access device 12 may be a network-side device in the wireless communication system. Among them, the wireless communication system can be the 4th generation mobile communication technology (the 4th generation mobile communication, 4G) system, also known as the Long Term Evolution (LTE) system; or the wireless communication system can also be a 5G system, Also called new radio (NR) system or 5G NR system. Alternatively, the wireless communication system may also be a next-generation system of the 5G system.

The access device 12 may be an evolved access device (eNB) used in the 4G system. Alternatively, the access device 12 may also be an access device (gNB) using a centralized distributed architecture in the 5G system. When the access device 12 adopts a centralized distributed architecture, it usually includes a centralized unit (central unit, CU) and at least two distributed units (distributed unit, DU). The centralized unit is equipped with a protocol stack including the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control protocol (Radio Link Control, RLC) layer, and the Media Access Control (Media Access Control, MAC) layer; distributed The unit is provided with a physical (Physical, PHY) layer protocol stack, and the embodiment of the present disclosure does not limit the specific implementation of the access device 12.

A wireless connection can be established between the access device 12 and the UE 11 through the wireless air interface. In different implementations, the wireless air interface is a wireless air interface based on the fourth generation mobile communication network technology (4G) standard; or the wireless air interface is a wireless air interface based on the fifth generation mobile communication network technology (5G) standard, such as The wireless air interface is a new air interface; alternatively, the wireless air interface may also be a wireless air interface based on the next generation mobile communication network technology standard of 5G.

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

S2110: In response to the terminal supporting the FD-FDD mode and HD-FDD mode, determine that the terminal operates in the FD-FDD mode or HD-FDD mode.

The terminal may be a regular terminal other than a reduced capability (RedCap) terminal. The terminal may be a terminal that supports both the FD-FDD mode and the HD-FDD mode. The terminal that supports both the FD-FDD mode and the HD-FDD mode may be a terminal that supports a hybrid (hybrid) FDD mode.

FDD mode means that the terminal's uplink transmission and downlink reception are set on different frequency bands. The frequency band used for uplink transmission is the uplink frequency band; the frequency band used for downlink reception is the downlink frequency band.

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

HD-FDD (half-duplex) mode means that uplink transmission and downlink reception in the FDD frequency band are performed in time and frequency division.

FD-FDD (full duplex) mode means that the terminal can perform uplink transmission and downlink reception on the FDD frequency band 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 3, the terminal may include an antenna, a duplexer connected to the antenna, and a switch, the switch being 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, inoperative 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.

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

Illustratively, the terminal determines that the terminal is working in the FD-FDD mode or HD-FDD mode according to the current network conditions and/or its own transmission requirements, thus standardizing the FDD mode of the terminal and ensuring that the terminal randomly selects an FDD mode. This results in a waste of power consumption or poor communication quality.

It is worth noting that the determination that the terminal operates in HD-FDD mode or FD-FDD mode may include: the FDD mode used by the terminal during the initial access phase, or the FDD mode used after the initial access phase.

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:

S2210: In response to the terminal supporting the FD-FDD mode and HD-FDD mode, determine that the terminal operates in the FD-FDD mode according to the default configuration.

Exemplarily, S2210 may include at least one of the following: in response to the terminal supporting FD-FDD mode and HD-FDD mode, after the terminal registers with the network, determine that the terminal works in the FD-FDD mode according to the default configuration. ;

In response to the terminal supporting the FD-FDD mode and the HD-FDD mode, when the operating mode indicated by network signaling is not received, it is determined that the terminal operates in the FD-FDD mode according to the default configuration.

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

Registration of the terminal to the network may include but is not limited to at least one of the following:

Initial access after the terminal is powered on;

Access after the terminal exits airplane mode;

The terminal accesses from an area without network coverage to an area with network coverage.

In some embodiments, if it is determined that the terminal operates in HD-FDD mode or FD-FDD mode based on other non-default configuration reference factors such as network signaling, network conditions, and/or the terminal's own transmission requirements, the terminal may use HD-FDD mode or FD-FDD mode determined according to the default configuration.

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:

S2310: In response to the terminal supporting the FD-FDD mode and HD-FDD mode, determine that the terminal operates in the FD-FDD mode or HD-FDD mode according to the access status information of the terminal.

If the terminal has been connected to the network for a period of time, and if the terminal supports FD-FDD mode and HD-FDD mode, you can consider whether the terminal is working in FD-FDD mode based on the access status of the terminal during the period of time it has been connected to the network. Or HD-FDD mode.

If the terminal fails to access repeatedly, it means that the current terminal needs higher transmit power to compete for access opportunities. Therefore, the terminal can be made to work in HD-FDD mode, so that the terminal can have higher transmit power to compete for access. opportunity to achieve network access. Of course, this is just an example, and the specific implementation is not limited to this.

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

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

In response to the terminal supporting the FD-FDD mode and the HD-FDD mode, when the number of consecutive access failures of the terminal is less than a second threshold, it is determined that the terminal operates in the FD-FDD mode.

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 upon in an agreement. The first duration may include a duration between one or more random access opportunities. For example, the first duration may include: one or more wireless frames.

The first number threshold may be 2, 3, 4, 5 or 6. Of course, this is just an example, and the specific value range can be determined based on historical access success rates and/or experimental values.

If the first duration is set, the terminal can start the timer according to the first duration. When the timer times out, when the number of terminal access failures is equal to or greater than the first number threshold, the terminal can be considered to be more suitable to work in HD- FDD mode.

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

If it is determined based on the number of consecutive access failures whether the terminal is currently working in HD-FDD mode or FD-FDD mode, there is no need to start a timer and only the number of consecutive access failures is required.

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

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

The reference signal includes but is not limited to synchronization signal block (SSB), channel state information reference signal and/or demodulation reference signal, etc.

If the network signal quality is good, the terminal can preferably choose to work in the FD-FDD mode in order to obtain a larger transmission bandwidth or to achieve synchronous execution of uplink transmission and downlink reception. Otherwise, the terminal can determine to work in the HD-FDD mode. .

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

In other embodiments, the first threshold may be determined according to the cell switching threshold of the terminal.

The measurement value includes but is not limited to: Reference Signal Receiving Power (RSRP) or Reference Signal Received Quality (RSRQ). If the measurement value is higher than the first threshold, it means that the network channel condition is good. The terminal can give priority to working in FD-FDD mode, otherwise it can give priority to working in HD-FDD mode.

The measured values may include, but are not limited to, measured values of various downlink signals.

In some embodiments, the terminal determines whether to operate in the HD-FDD mode or the FD-FDD mode on its own based on the measured value of the downlink signal.

In response to the terminal supporting the FD-FDD mode and the HD-FDD mode, it is determined that the terminal operates in the FD-FDD mode based on the fact that the number of data retransmissions by the terminal within the third time period is less than the second number threshold.

The second duration can be any duration. For example, the second duration may be a duration negotiated between the terminal and the base station, or a duration agreed upon in the agreement. The second duration may include a duration between one or more random access opportunities. For example, the second duration may include: one or more wireless frames.
