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

s1110: the UE meeting the preset condition is switched between a full duplex FDD mode and a preset working mode, wherein the preset working mode comprises: a time division duplex TDD mode or a half duplex HD-frequency division duplex FDD mode.

The UEs meeting the preset conditions in the embodiments of the present disclosure are: a UE supporting both an FDD mode or HD-FDD mode and/or both FDD and TDD modes.

The FDD mode may be: the UE works on the uplink frequency band and the downlink frequency band at the same time point, so that the UE can perform uplink transmission and can perform downlink reception synchronously.

The TDD mode may be: the time domain is allocated to an uplink transmitting unit and a downlink receiving unit, wherein the uplink transmitting unit transmits uplink data to the UE, and the downlink receiving unit receives downlink data.

HD-FDD mode: the UE works in an uplink frequency band or a downlink frequency band at one moment, and works in the uplink frequency band to perform uplink transmission and works in the downlink frequency band to perform downlink reception.

As such, the UE may switch between FDD mode and TDD mode, or between FDD mode and HD-FDD mode, depending on the communication needs. In an exemplary embodiment, the UE may operate in an FDD mode when uplink transmission and downlink reception are required at the same time, and may operate in a TDD or HD-FDD mode when higher transmission power is required, so as to meet the communication requirements of the UE in different situations, thereby improving the communication quality of the UE.

In some embodiments, the UE satisfying a preset condition includes: a diplexer and a switch in parallel with the diplexer;

if the switch is disconnected, the duplexer is conducted, and the UE supports simultaneous uplink transmission and downlink reception;

if the switch is turned on, the duplexer is shorted, and the UE supports uplink transmission or downlink reception.

The switch is connected in parallel with the diplexer and may be referred to as a bypass switch.

If the duplexer is conducted, the duplexer enters into a working state. The duplexer in the working state supports both uplink transmission and downlink reception, so if the duplexer is turned on, the UE can work in FDD mode supporting both uplink transmission and downlink reception.

If the diplexer is not on, but the switch is closed, the branch where the switch is located can only support uplink transmission or downlink reception at one time, so that the UE can operate in TDD mode or HD-FDD mode.

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.

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

s1210: when the switch connected in parallel with the duplexer is turned on, the UE enters a preset working mode, wherein the preset mode is a TDD mode or an HD-FDD mode.

In this state, the diplexer shorts the switch that is turned on.

If the UE needs to transmit uplink with a larger transmit power, the processor or the controller of the UE controls the switch to be turned on, so that the duplexer enters a non-working state, and uplink transmission or downlink reception with a larger transmit power is realized.

The information processing method provided by the embodiment of the disclosure can be independently executed or can be implemented in combination with any other information processing method executed by the UE.

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

s1310: when a switch connected in parallel with the duplexer is turned off, the UE enters an FDD mode.

For example, the UE measures the transmission with good cell signal quality and more frequent uplink and downlink, and the processor or controller of the UE turns off the switch so that the duplexer turns on to enter FDD mode supporting both uplink and downlink reception.

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

s1410: the UE meeting the preset condition is switched between a full duplex FDD mode and a preset working mode; the preset working modes at least comprise: a TDD mode;

s1420: and when the UE works in the TDD mode, uplink transmission or downlink reception is carried out.

If the UE is in the TDD mode, the UE performs uplink transmission or downlink reception at one time.

This embodiment may be implemented alone or in combination with any of the foregoing embodiments.

When the UE is in TDD mode, collision between uplink transmission and downlink reception may occur, and in the embodiment of the present disclosure, the UE may determine coordination between uplink transmission and downlink reception based on DL-UL pattern.

Illustratively, the S1420 may include: and when the UE works in the TDD mode, uplink transmission or downlink reception is carried out on a specific subframe.

Illustratively, when the UE is operating in the TDD mode, the uplink transmission or downlink reception is performed, including at least one of:

DL is performed at a DL receiving unit according to a downlink DL-uplink UL pattern;

UL is performed at UL transmission unit according to downlink DL-uplink UL pattern;

DL or UL is performed in a flexible transmission unit according to the downlink DL-uplink UL pattern and scheduling information;

and carrying out DL or UL in a flexible transmission unit according to the transmission requirement of the UE according to a downlink DL-uplink UL pattern.

In some embodiments, the DL-UL pattern may include: DL receiving unit and/or UL transmitting unit.

In other embodiments, the DL-UL pattern may further include: flexible transmission units.

The DL receiving unit may be used for DL reception and is a DL reception subframe, a DL reception slot, a DL reception minislot, or a DL reception symbol.

The UL transmission unit may be for UL transmission and may be a UL transmission subframe, a UL transmission slot, a UL reception micro slot, or a UL transmission symbol.

In some embodiments, the DL-UL pattern may also include flexible transmission units, i.e., transmission units not defined in the DL-UL pattern for DL reception or UL transmission. As such, the flexible transmission unit may be flexibly used by the UE and the base station.

The flexible transmission unit may include: subframes, slots, minislots, symbols, or the like, whether UL transmission or DL reception are not explicitly defined.

In one embodiment, the base station may schedule the flexible transmission unit, so that the UE may perform uplink transmission and/or downlink reception according to the scheduling information. For example, the base station may transmit the scheduling information through downlink control information (Downlink Control Information, DCI) or an RRC message or MAC CE.

In other embodiments, the base station may send scheduling information for the flexible transmission unit, and the UE may perform UL transmission or DL reception on the flexible transmission unit according to its own transmission requirement.

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

s1510: the UE meeting the preset condition is switched between a full duplex FDD mode and a preset working mode; the preset working modes at least comprise: HD-FDD mode;

s1520: and when the UE works in the HD-FDD mode, carrying out DL receiving or UL transmitting according to the priority.

If the UE is operating in HD-FDD mode, collisions of DL reception and UL transmission may occur. Such collision is the need for both DL reception and UL transmission at one time.

To resolve this conflict, one way is: the transmission with high priority is performed according to the priority of the DL reception and UL transmission of the collision. For example, if the priority of UL transmission is high, the UE preferentially performs UL transmission; if the priority of DL reception is high, the UE preferentially performs DL reception. And the same priority of DL reception and UE transmission of collision is an abnormal situation that neither UE nor network device expects to occur. If such an abnormal situation occurs, the UE may choose to perform neither DL reception nor UL transmission, or perform DL reception or UL transmission randomly.

Illustratively, the priority of dynamically scheduled transmissions is higher than the priority of semi-statically scheduled transmissions.

Typically, dynamically scheduled transmissions are relatively urgent transmissions, so the priority may be higher than the priority of a semi-static transmission that was completed in advance. That is, normally, if there is a collision between a dynamically scheduled transmission and a semi-static transmission, the dynamically scheduled UL transmission or DL reception is prioritized.

For example, if there is a collision between two dynamically scheduled transmissions, one of the transmissions may be selected according to priority. Also, for example, if there is a collision between two transmissions scheduled semi-statically, one of the transmissions may be selected according to priority. In summary, if the UE is operating in HD-FDD mode, the UE may prioritize high priority transmissions.

In some embodiments, when the UE is operating in the HD-FDD mode, DL reception or UL transmission is performed according to priority, including at least one of:

when semi-static UL transmissions other than UL associated with random access collide with dynamically scheduled DL reception, dynamically scheduled DL transmissions are made;

and when the semi-static UL transmission associated with the random access collides with the dynamic scheduling DL reception, carrying out the semi-static UL transmission associated with the random access, or carrying out the dynamic scheduling DL transmission or the semi-static UL transmission associated with the random access according to a first UE strategy.

In the embodiment of the present disclosure, the semi-static UL transmission except for the UL associated with the random access is: any other semi-static UL transmission than the radius UL transmission associated with random access.

In some embodiments, the semi-static UL associated with random access includes random access occasions RO and/or physical uplink shared channel PUSCH transmissions of random access message a.

Illustratively, the semi-static UL associated with random access includes: and the Physical Uplink Shared Channel (PUSCH) of the effective random access opportunity (RO) and/or the random access message (A) is transmitted.

In some embodiments, a network device such as a base station may define a portion of the resources of a physical random access channel (Physical Random Access Channel, PRACH) as active resources and another portion as idle resources. And the ROs contained in the valid resources of the RPACH are valid ROs. The UE may be able to send a random access request on a valid RO without sending the random access request within the RO contained in the idle resource.

The physical uplink shared channel PUSCH transmission of the random access Message (Msg) a may include: uplink data transmitted on PUSCH by MsgA. The MsgA may be a message a in two-step random access, and may be configured on PUSCH. The UE may send a small amount of data to the base station using MsgA on PUSCH without performing a complete random access procedure.

In the embodiment of the disclosure, the semi-static UL transmission associated with the random access has a higher priority than other semi-static UL transmissions, so that when the semi-static UL transmission associated with the random access collides with the dynamically scheduled DL transmission, the UE may select one to execute according to a first UE policy defined by itself.

Meanwhile, when the semi-static UL transmission associated with the random access and the dynamically scheduled UL transmission collide, the UE may also select one to execute according to the self-defined first UE policy.

The first UE policy may be any policy defined by the UE itself, for example, the UE may perform dynamically scheduled DL transmissions or semi-static transmissions associated with random access according to the first policy.

when the UE works in the HD-FDD mode, if the semi-static UL associated with random access collides with the semi-static DL transmission associated with the search space SS, semi-static UL associated with random access or semi-static DL transmission associated with the search space SS is carried out according to a second UE strategy;

when the UE works in the HD-FDD mode, if the DL transmission of the semi-static UL associated with the random access and the DL transmission of the semi-static configured reference signal conflict, carrying out the DL transmission of the semi-static UL associated with the random access or the DL transmission of the semi-static configured reference signal according to a third UE strategy;

and when the UE works in the HD-FDD mode, if the semi-static UL associated with the random access and the semi-static configured physical downlink shared channel PDSCH transmission conflict, carrying out the semi-static UL associated with the random access or the semi-static configured physical downlink shared channel PDSCH transmission according to a fourth UE strategy.

Illustratively, the semi-static DL associated with the search space SS includes at least one of:

semi-static DL associated with a common search space (Common Serach Space, CSS);

semi-static transmissions associated with a user-specific space (User Specifc Space, USS).

The search space may include: a common search space shared by a plurality of UEs in a cell and USS used by a single user.

CSS may be used for all UEs searching for PDCCH transmissions, while USS may be used for specific user searching for PDCCH transmissions.

In some embodiments, the semi-statically configured reference signal comprises at least one of:

channel state information, CSI, reference signal, RS;

positioning reference signals PRS.

Of course, the foregoing is merely an example of SS and reference signals, and the specific implementation is not limited to the foregoing examples.

The second UE policy, the third UE policy and the fourth UE policy are all UE policies, and the UE may be determined by UE customization according to the equipment provider configuration information or the communication carrier configuration information.

In some embodiments, the performing semi-static UL associated with random access or semi-static DL transmission associated with search space SS according to a second UE policy includes:

according to a second UE strategy, semi-static UL associated with random access is preferentially carried out;

Or,

and according to the second UE strategy, the semi-static DL transmission associated with the search space SS is preferentially carried out.

In some embodiments, DL transmission of a semi-static UL or semi-static configured reference signal associated with random access according to a third UE policy may include:

according to a third UE policy, semi-static UL associated with random access may be preferentially performed;

or,

DL transmission of semi-statically configured reference signals may be prioritized according to a third UE policy.

In some embodiments, the performing, according to a fourth UE policy, a physical downlink shared channel PDSCH transmission of a semi-static UL or semi-static configuration associated with random access, includes:

according to a fourth UE strategy, semi-static UL associated with random access is preferentially carried out;

or,

and according to the fourth UE strategy, the physical downlink shared channel PDSCH transmission with semi-static configuration is preferentially carried out.

when semi-static UL transmissions other than the synchronization signal block SSB collide with dynamically scheduled DL reception, dynamically scheduled DL transmissions are made;

when the semi-static UL transmission of the SSB collides with the dynamically scheduled DL reception, performing the semi-static UL transmission of the SSB;

When the semi-static UL transmission of the SSB collides with the transmission of a semi-static Physical Uplink Control Channel (PUCCH), performing the semi-static UL transmission of the SSB;

when the semi-static UL transmission of the SSB collides with the UL transmission associated with the random access, the semi-static UL of the SSB or the UL transmission associated with the random access is performed according to a fifth UE policy.

SSB may include: primary synchronization signal, secondary synchronization signal and physical broadcast channel (Physical Broadcast Channel, PBCH) transmissions.

The SSB may be used for synchronizing the UE with network devices such as base stations.

The RF side of the UE has a duplexer and a switch, and when the UE is operating in a supported simultaneous transmit-receive mode, UE transmissions are multiplexed by the duplexer. When the RF side of the UE is operating in a mode that does not support simultaneous transceiving, a switch bypasses the duplexer. However, since the duplexer has a loss of about 4dB and the switch has a smaller loss, the maximum transmission power that can be provided in the different transceiving modes is greater.

When the UE is operating in the simultaneous transceiving mode, the UE may still use the existing FDD mode of operation. Then how the UE should coordinate the transmissions with the base station when the UE is operating in a mode where simultaneous transmissions are not possible.

The response may be in a TDD mode or an HD-FDD mode in which the UE is operating in a mode where simultaneous transceiving is not possible.

The operation of the UE in TDD mode may be as follows:

at this time, the UE and the base station can perform transmit-receive coordination by multiplexing uplink and downlink determination modes of TDD.

Specifically, the network configures a DL-UL pattern (pattern). I.e. the UE is informed of subframes for DL reception and/or UL transmission by signaling indicating the DL-UL pattern.

In an embodiment, the DL-UL pattern may further configure a flexible subframe, that is, the flexible subframe may be used for both uplink transmission and downlink reception, and whether a specific flexible subframe is used for uplink transmission or downlink reception depends on scheduling of network side devices such as a base station, on the one hand, and on the other hand, may depend on transmission requirements of the UE.

For example, the network device such as the base station schedules the UE to perform downlink reception in the flexible subframes, and then the UE may perform information reception in the corresponding flexible subframes. If the UE is scheduled for uplink transmission, the UE performs uplink transmission in the corresponding flexible subframes according to the scheduling information of the network.

The operation of the UE in HD-FDD mode may be as follows:

in this operation mode, the network device such as the base station does not specify the uplink and downlink transmission subframes, but solves this by means of network scheduling.

For example, the network device such as the base station schedules the UE to perform downlink transmission, and then the UE performs information reception on the corresponding transmission unit. If the UE is scheduled to perform uplink transmission, the UE performs uplink transmission in the corresponding transmission subframe according to the scheduling information of the network.

Referring to fig. 7 to 11, in this operation mode, a collision of the uplink and downlink transmissions may be found, and then the following rule is used for collision processing:

case 1: dynamically scheduled DL reception and removal of semi-statically scheduled UL transmission collisions associated with random access;

case 2: semi-static DL reception and dynamically scheduled UL transmission collisions other than SSB; the dynamically scheduled UL transmission may include: dynamically scheduled PDCCH transmissions for triggering PRACH.

In both case 1 and case 2, dynamically scheduled transmissions are preferentially performed.

Case 3: the UL transmission unit collides with dedicated semi-static UL transmissions of the UE;

case 4: dynamically scheduled UL transmissions and dynamically scheduled DL receptions;

case 3 and case 4 are cases where the UE does not expect to occur, and the UE may consider as an abnormal case. In an abnormal situation, the UE may not perform any one of the transmissions.

Case 5: semi-static DL reception of SSB collides with dynamically scheduled SRS, UL transmission of configured PUCCH, dynamically scheduled transmission of PUCCH transmission other than random access Msg3 transmission and Msg4 transmission, respectively; in case 5: if the semi-static DL reception of the SSB collides with the dynamically scheduled SRS, the UL transmission of the configured PUCCH, and the dynamically scheduled transmission except for the random access Msg3 transmission and the PUCCH transmission of the Msg4, the semi-static DL reception of the SSB is preferentially performed.

Case 6: : collisions between UL transmissions of semi-static DL received active ROs of SSBs.

If there is a collision between the semi-static DL reception of SSB and UL transmission of the valid RO, it is determined by the UE itself.

Case 7: the UL transmission of the effective RO, the DL reception of the dynamic scheduling, the DL reception of the cell-specific semi-static scheduling, and the DL reception transmission of the UE-specific configuration.

In case 7, the UE will choose to either DL receive or UL transmit depending on its implementation policy.
