As a possible solution, the network side schedules or instructs the full duplex terminal to transmit or receive data on a semi-static variable symbol (semi-static flexible symbol).

These terms are only used to distinguish one type of information from another. For example, first information may also be referred to as second information, and similarly, second information may also be referred to as first information, without departing from the scope of the present disclosure. The word "responsive to" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.

In an NR (new radio) system, a base station may configure a cell-level uplink and downlink time division duplex configuration (TDD UL-DL configuration) through an uplink and downlink time division duplex common configuration (TDD-UL-DL-configuration) carried in a system information block1 (System Information Block, SIB 1).

Further, in response to the base station configuring uplink and downlink time division duplex dedicated configuration (TDD-UL-DL-configuration) carried by radio resource control (Radio Resource Control, RRC) signaling, TDD UL-DL configuration may be determined by both.

The TDD UL-DL configuration contains three types of time domain resources:

semi-static DL symbol;

semi-static uplink symbol (semi-static UL symbol);

semi-static flexible symbol。

the transmission directions of semi-static DL symbol and semi-static UL symbol cannot be changed, and semi-static flexible symbol may dynamically adjust the transmission directions through SFI, for example, indicated as UL, DL or flexible. In the related protocol, for the transmission direction indicated by the SFI, there is defined as follows:

for UL symbol indicated by SFI, the terminal transmits uplink thereon;

for DL symbol indicated by SFI, the terminal receives downlink thereon;

for the flexible symbol indicated by the SFI, the terminal performs any transmission and reception thereon according to the received base station indication.

When the transmission direction indicated by the SFI collides with the transmission direction of the sub-band scheduled by the base station on semi-static flexible symbol, the terminal has different terminal behaviors on the semi-static flexible symbol, which may cause inconsistent understanding of the terminal behaviors by the base station side and the terminal side.

In order to solve the technical problems, the present disclosure provides the following method, device and storage medium for determining terminal behavior.

The method for determining terminal behavior provided by the present disclosure is described first from the terminal side.

in step 101, the terminal type is determined.

In the embodiments of the present disclosure, the terminal type may be a full duplex terminal or a non-full duplex terminal. The full duplex terminal refers to a terminal capable of performing UL/DL transmission on DL/UL symbols configured or indicated by the base station, and the non-full duplex terminal refers to a terminal capable of performing UL/DL transmission only according to the indication or configuration of the network.

Determining terminal behavior of the terminal on a specified time unit based on the terminal type in step 102; the appointed time unit is a time unit with a variable transmission direction which is preconfigured by the base station.

In one possible implementation, the specified time unit may be semi-static flexible symbol.

In one possible implementation, the specified time unit may be configured by tdd-UL-DL-configurationcommand carried in SIB1 sent by the base station.

In another possible implementation, the specified time unit may be configured by a tdd-UL-DL-configuration command carried in SIB1 sent by the base station and dd-UL-DL-configuration defined in RRC signaling sent by the base station.

In the above embodiment, the terminal may determine the terminal behavior based on the predefined rule on the designated time unit with the variable transmission direction, so as to ensure that the understanding of the base station and the terminal on the designated time unit is consistent, thereby improving the feasibility of full duplex communication.

In some alternative embodiments, referring to fig. 2, fig. 2 is a flowchart illustrating a method for determining terminal behavior, which may be performed by a terminal, according to an embodiment, the method may include the steps of:

in step 201, the terminal type is determined.

In the embodiments of the present disclosure, the terminal type may be a full duplex terminal or a non-full duplex terminal. The full duplex terminal refers to a terminal capable of transmitting or receiving data according to the instruction of the base station on the semi-static variable symbol, and the non-full duplex terminal refers to a terminal only supporting data reception or data transmission on the semi-static variable symbol.

In step 202, in response to the terminal type being a full duplex terminal, it is determined that the terminal supports transmission of data or reception of data over a specified time unit, and it is determined that a first transmission direction of a sub-band that the terminal supports transmission over the specified time unit is different from a second transmission direction of the specified time unit indicated by a slot format indicator SFI.

In the embodiment of the present disclosure, the specified time unit is a time unit with a variable transmission direction preconfigured by the base station.

In the embodiment of the present disclosure, specifically, the terminal supports data transmission or data reception on the specified time unit, and at the same time, the terminal also supports any one of the following cases:

The first transmission direction of the sub-band transmitted on the appointed time unit is uplink, and the second transmission direction of the same appointed time unit indicated by the SFI transmitted by the base station is downlink;

the first transmission direction of the sub-band transmitted on the appointed time unit is uplink, and the second transmission direction of the same appointed time unit indicated by the SFI transmitted by the base station is variable;

the first transmission direction of the sub-band transmitted on the appointed time unit is downlink, and the second transmission direction of the same appointed time unit indicated by the SFI transmitted by the base station is uplink;

the first transmission direction of the sub-band transmitted on the appointed time unit is downlink, and the second transmission direction of the same appointed time unit indicated by the SFI sent by the base station is variable.

In the above embodiment, the terminal may first determine the terminal type based on the predefined rule and determine the terminal behavior based on the terminal type on the designated time unit with the variable transmission direction, so as to ensure that the understanding of the base station and the terminal on the designated time unit is consistent, thereby improving the feasibility of full duplex communication.

In some alternative embodiments, referring to fig. 3, fig. 3 is a flowchart illustrating a method for determining terminal behavior, which may be performed by a terminal, according to an embodiment, the method may include the steps of:

In step 301, the terminal type is determined.

In step 302, in response to the terminal type being a full duplex terminal, determining a terminal behavior of the terminal on a specified time unit based on an indication of radio resource control RRC signaling sent by the base station.

In the embodiment of the present disclosure, when the terminal determines that its own terminal type is a full duplex terminal, the terminal may receive RRC signaling sent by the base station, where the RRC signaling is used to indicate whether the base station performs full duplex operation on the specified time unit. The terminal determines a terminal behavior of the terminal over a specified time unit based on the indication of the RRC signaling. The appointed time unit is a time unit with a variable transmission direction which is preconfigured by the base station.

The specific implementation is similar to step 202 and will not be described again.

In another possible implementation, the RRC signaling indicates that the base station does not perform full duplex operation on the specified time unit, and determines that a first transmission direction of a subband scheduled by the base station on the specified time unit is the same as a second transmission direction of the specified time unit indicated by a slot format indicator SFI.

That is, in response to the base station scheduling an uplink sub-band in a specified time unit, when the first transmission direction is uplink, the base station indicates that the second transmission direction of the same specified time unit is also uplink through the SFI, and the base station does not indicate that the second transmission direction of the same specified time unit is downlink or variable through the SFI.

Or, in response to the base station scheduling the downlink sub-band on the specified time unit, when the first transmission direction is downlink, the base station indicates that the second transmission direction of the same specified time unit is downlink through the SFI, and the base station does not indicate that the second transmission direction of the specified time unit is uplink or variable through the SFI.

Still alternatively, the base station may not schedule the uplink sub-band on the same designated time unit in response to the base station having indicated the second transmission direction of the designated time unit as downlink or variable via the SFI.

Still alternatively, the base station may not schedule the downlink sub-band on the same designated time unit in response to the base station having indicated the second transmission direction of the designated time unit as uplink or variable via the SFI.

In some alternative embodiments, in response to the terminal determining that its own terminal type is a non-full duplex terminal, the first transmission direction of the sub-band scheduled by the base station over the specified time unit is the same as the second transmission direction of the same specified time unit indicated by the SFI.

In the above embodiment, when the terminal type is a non-full duplex terminal, the first transmission direction of the sub-band scheduled by the base station in the specified time unit is the same as the second transmission direction of the same specified time unit indicated by the SFI. The method can also ensure that the base station and the terminal understand the terminal behavior consistently in a designated time unit, and the availability is high.

The method and the device achieve the aim of ensuring consistent understanding of the base station and the terminal to the terminal behaviors on the appointed time unit, and improve the feasibility of full duplex communication.

In some alternative embodiments, in response to the base station determining that the first indication information or the second indication information reported by the terminal is not received, the base station may determine that the terminal type of the terminal is a non-full duplex terminal, and then determine that the first transmission direction of the sub-band supported by the terminal for transmission on the specified time unit is the same as the second transmission direction of the specified time unit indicated by the slot format indicator SFI. I.e. it is determined that the first transmission direction of the sub-band that the terminal does not expect the base station to schedule on a given time unit is different from the second transmission direction of the same given time unit indicated by the SFI.

In some alternative embodiments, the subbands transmitted on the designated time units may be UL subbands or DL subbands, which may be configured by the base station through explicit signaling or acquired by the terminal through implicit means, which is not limited in this disclosure. The above method is further exemplified below.

In embodiment 1, the terminal is a Rel-18 and subsequent terminals, which have half duplex capability or full duplex capability, and the patent is not limited in any way. It is assumed that the base station side performs full duplex operation on semi-static flexible symbol of the TDD band, that is, performs scheduling of downlink data and uplink data at the same time. The semi-static flexible symbol can be determined by the following information transmitted by the base station:

tdd-UL-DL-ConfigurationCommon；

tdd-UL-DL-ConfigurationCommon、tdd-UL-DL-ConfigurationDedicated。

the base station indicates the transmission direction of the terminal on the semi-static flexible symbol in the following two ways, which is not limited in this embodiment:

and the base station configures UL (uplink) subband or DL (downlink) subband for the terminal. In the UL subband, the terminal can only perform uplink transmission; in the DL subband, the terminal can only perform uplink reception. The base station performs scheduling of a data channel or indication of a reference signal in the UL subband or DL subband.

The base station instructs the terminal to transmit or receive on the semi-static symbol through scheduling information or higher layer configuration. The base station does not need to explicitly configure UL subband or DL subband for the terminal.

Further, the base station indicates the transmission direction of the semi-static flexible symbol through the SFI, that is, indicates the semi-static flexible symbol as DL, UL or dynamic flexible according to the service condition or the interference condition.

In this embodiment, it is assumed that the slot structure configured by the base station through TDD UL-DL configuration is DFFFF, that is, in the TDD configuration period, the first slot is DL slot, and the remaining 4 slots are flexible slots, as shown in fig. 9A. Of course, the embodiment method can be directly applied to other TDD UL DL slot structures.

In the embodiment of the present disclosure, it is assumed that the base station schedules uplink transmission on UL subband on the semi-flexible symbol, that is, on the last 4 slots shown in fig. 9A, an uplink subband is configured, as shown in fig. 9B. It should be noted that the uplink transmission may be uplink data or uplink reference signals, which is not limited in this patent.

In this embodiment, it is assumed that the duplex terminal supports data transmission or data reception on semi-static flexible symbol, and supports that the first transmission direction of the subband is different from the second transmission direction of the semi-static flexible symbol indicated by the SFI. The duplex terminal may report the first indication information or the second indication information to the base station, so as to report the terminal type of the duplex terminal or whether the terminal capability of the duplex communication capability is specific to the base station. And the base station determines whether the first transmission direction of the terminal supporting the subband is different from the second transmission direction of the semi-static flexible symbol indicated by the SFI according to the first indication information or the second indication information reported by the terminal.

Referring to fig. 10, in response to the terminal type being a full duplex terminal, it is determined that the terminal supports transmission of data or reception of data on the last 4 slots, and that a first transmission direction (uplink) of a subband transmitted on the last 4 slots supported by the terminal is different from a second transmission direction of the last 4 slots indicated by the SFI.

Assume that the second data transmission direction indicated by the SFI sent by the base station is: DDDSU. Wherein D represents downstream, S represents variable, and U represents upstream. I.e. the terminal supports a first transmission direction (uplink) on the 2 nd, 3 rd, 4 th slot different from a second transmission direction (DDS) indicated by the SFI.

Further, in response to the base station not receiving the first indication information or the second indication information reported by the terminal, the base station may determine that the terminal type of the terminal is a non-full duplex terminal, and the base station may not indicate a time slot structure opposite to the first transmission direction of the sub-band thereof through the SFI. Referring to fig. 10, in response to the base station configuring the uplink sub-band on the last 4 slots, the slot structure of the last 4 slots indicated by the SFI sent by the base station should be: uuuuu.

Note that DL symbol or flexible symbol indicated by the SFI partially or completely coincides with uplink transmission of the terminal in UL subband, which is not limited in the present disclosure.

In embodiment 2, the terminal is a Rel-18 and subsequent terminals, which have half duplex capability or full duplex capability, and the present patent is not limited in any way. It is assumed that the base station side performs full duplex operation on semi-static flexible symbol of the TDD band, that is, performs scheduling of downlink data and uplink data at the same time. The semi-static flexible symbol can be determined by the following information transmitted by the base station:

tdd-UL-DL-ConfigurationCommon；

tdd-UL-DL-ConfigurationCommon、tdd-UL-DL-ConfigurationDedicated。

In this embodiment, the base station determines, through the first indication information or the second indication information reported by the terminal, that the terminal type is a full duplex terminal, and then the base station indicates, through RRC signaling, whether the base station performs full duplex operation on semi-static flexible symbol. Further, the base station and the terminal determine terminal behavior of the full duplex terminal through the RRC signaling:

in response to the base station performing full duplex operation on semi-static flexible symbol, the full duplex terminal supports data transmission or data reception on a flexible symbol, and determines that a first transmission direction of the terminal supporting subband is different from a second transmission direction indicated by the SFI. The specific implementation is similar to the implementation of fig. 10 and will not be described again here.

In response to the base station not performing full duplex operation on the semi-static flexible symbol, the terminal may employ an existing mechanism in which the first transmission direction of the sub-band scheduled by the base station is the same as the second transmission direction indicated by the SFI. Correspondingly, the base station does not indicate the time slot structure opposite to its scheduling direction through the SFI.

In the above embodiment, the base station and the terminal may determine the terminal behavior based on the predefined rule on the designated time unit with the variable transmission direction, so as to ensure that the understanding of the base station and the terminal on the designated time unit is consistent, thereby improving the feasibility of full duplex communication.
