The full-duplex solution is studied in the Release-18 (Rel-18) full-duplex enhancement project. Specifically, the base station can send and receive data simultaneously in one time slot.

For TDD carriers, there are currently multiple TDD time slot structures, including but not limited to the following TDD time slot structures:

Single-cycle TDD slot structure configured by common TDD configuration (tdd-UL-DL-ConfigurationCommon);

Dual-periodic TDD slot structure configured via tdd-UL-DL-ConfigurationCommon;

TDD slot structure configured by tdd-UL-DL-ConfigurationCommon and dedicated TDD configuration (tdd-UL-DL-ConfigurationDedicated);

The base station is not configured with any TDD UL-DL configuration, that is, all Orthogonal Frequency Division Multiplexing (OFDM) symbols are flexible symbols.

Among them, the TDD time slot structure configured by tdd-UL-DL-ConfigurationDedicated also includes a single-period TDD time slot structure and a dual-period TDD time slot structure.

Among them, flexible symbol refers to a symbol with variable transmission direction. The base station can configure the transmission direction on the flexible symbol as uplink or downlink according to actual needs.

Based on the current TDD time slot structure, it can be seen that the current frame structure is very flexible, and there may be multiple continuous downlink (DownLink, DL) symbols, uplink (UpLink, UL) symbols or flexible symbols.

Currently, there are still few specific solutions on how to indicate subband time domain resources under the above different TDD time slot structures.

In order to solve the above technical problems, the present disclosure provides a resource determination method and device, and a storage medium.

The following first introduces the resource determination method provided by the present disclosure from the terminal side.

The present disclosure provides a resource determination method, as shown in FIG1 , which is a flow chart of a resource determination method according to an embodiment, which can be executed by a terminal. The method may include the following steps:

In step 101, first indication information sent by a base station is received.

In the embodiment of the present disclosure, the first indication information is used to indicate the time domain resource position occupied by the subband in the first time unit.

The first time unit may be a Seamless Bidirectional Forwarding Detection (SBFD) time unit, wherein the SBFD time unit is a time unit on which information transmission in different transmission directions may be performed.

Exemplarily, the SBFD time unit may be a downlink time unit including an uplink subband, or a variable time unit including an uplink subband (i.e., a time unit with a variable transmission direction), or an uplink time unit including a downlink subband, or a variable time unit including a downlink subband, and the present disclosure does not limit this.

The first time unit may be a slot, a symbol, or a duration (span), etc., which is not limited in the present disclosure. A span includes multiple continuous symbols.

In step 102, based on the first indication information, the time domain resource position occupied by the subband in the first time unit is determined.

In the embodiment of the present disclosure, the terminal determines the time domain resource position occupied by the subband in the first time unit based on the first indication information sent by the base station.

In a possible implementation, the first indication information includes RIV. After the value of RIV is determined, the terminal can determine the starting time domain resource position and the number of duration units corresponding to the RIV sent by the base station according to the correspondence between the RIV and the starting time domain resource position and the number of duration units. Thus, based on the starting time domain resource position and the number of duration units, the time domain resource position occupied by the subband on the first time unit is determined.

In another possible implementation, the first indication information may include a bitmap. The terminal may determine the time domain resource position corresponding to the bit position having the first bit value in the bitmap as the time domain resource position occupied by the subband in the first time unit.

In the above embodiment, the terminal can accurately determine the time domain resource position occupied by the subband in the first time unit under any TDD time slot structure based on the first indication information sent by the base station, thereby improving the reliability of full-duplex communication and high availability.

In some optional embodiments, the first indication information is used to indicate the time domain resource position occupied by the subband in the first time unit. The first time unit may include a time unit located in a period indicated by the common TDD time slot structure and having a transmission direction opposite to that of the subband.

In the disclosed embodiment, the common TDD time slot structure may be a TDD time slot structure that can be used in common by multiple terminals configured by the base station side for the terminal through tdd-UL-DL-ConfigurationCommon. The base station side may carry the tdd-UL-DL-ConfigurationCommon through System Information Block 1 (SIB1).

In an embodiment of the present disclosure, the terminal may determine the time domain resource position occupied by the subband on the first time unit in the common TDD time slot structure based on the first indication information sent by the base station. The first time unit may be in units of slot, symbol or span, etc., which is not limited in the present disclosure.

For example, the terminal determines the time domain resource position occupied by the uplink subband on the downlink symbol in the common TDD time slot structure based on the first indication information sent by the base station.

For another example, the terminal determines the time domain resource position occupied by the downlink subband on the uplink symbol included in the common TDD time slot structure based on the first indication information sent by the base station.

Exemplarily, the common TDD time slot structure may include one cycle, ie, a single cycle.

Accordingly, the terminal may determine the time domain resource position occupied by the uplink subband on the downlink symbol within the single cycle indicated by the common TDD time slot structure based on the first indication information sent by the base station. Alternatively, the terminal may determine the time domain resource position occupied by the downlink subband on the uplink symbol within the single cycle indicated by the common TDD time slot structure based on the first indication information sent by the base station.

Exemplarily, the common TDD time slot structure may include multiple cycles, such as a double cycle.

The first indication information can be used to indicate the time slot resource position occupied by the subband on each of the first time units within the multiple periods. Accordingly, the terminal can determine the time domain resource position occupied by the uplink subband on all downlink symbols within the multiple periods indicated by the common TDD time slot structure based on the first indication information sent by the base station. Alternatively, the terminal can determine the time domain resource position occupied by the downlink subband on all uplink symbols included in the multiple periods indicated by the common TDD time slot structure based on the first indication information sent by the base station.

Alternatively, when the first indication information is used to indicate the time slot resource position occupied by the subband on each of the first time units included in each of the periods within multiple periods, the terminal can determine the time domain resource positions occupied by the uplink subbands on all downlink symbols included in each period indicated by the common TDD time slot structure based on the first indication information. Alternatively, the terminal can determine the time domain resource positions occupied by the downlink subbands on all uplink symbols included in each period indicated by the common TDD time slot structure based on the first indication information sent by the base station.

Taking the common TDD time slot structure including dual periods as an example, namely period P1 and period P2, illustratively, the terminal can determine the time domain resource position occupied by the uplink subband on all downlink symbols in P1 and P2 based on the first indication information. Or determine the time domain resource position occupied by the downlink subband on all uplink symbols included in P1 and P2.

Exemplarily, the terminal may determine, based on the first indication information, the time domain resource positions occupied by the uplink subbands on all downlink symbols included in P1, and determine the time domain resource positions occupied by the uplink subbands on all downlink symbols included in P2.

Alternatively, the time domain resource positions occupied by the downlink subbands on all uplink symbols included in P1 are determined, and the time domain resource positions occupied by the downlink subbands on all uplink symbols included in P2 are determined.

Of course, the first indication information sent by the base station may also only indicate the time domain resource position occupied by the subband on the first time unit within P1 or P2. Based on the first indication information, the terminal determines the time domain resource position occupied by the subband on the first time unit within P1 or P2.

In the above embodiment, the terminal can determine the time domain resource range occupied by the subband on the first time unit within the period indicated by the common TDD time slot structure based on the first indication information sent by the base station, wherein the transmission direction of the first time unit is opposite to the transmission direction of the subband. The reliability of full-duplex communication is improved, and the availability is high.

In some optional embodiments, the first indication information is used to indicate the time domain resource position occupied by the subband in the first time unit. The first time unit may include a time unit located in a period indicated by the terminal-specific TDD time slot structure and having a transmission direction opposite to that of the subband.

The terminal-dedicated TDD time slot structure may be a terminal-dedicated TDD time slot structure configured for the terminal by the base station side through tdd-UL-DL-ConfigurationDedicated. The base station side may carry the tdd-UL-DL-ConfigurationDedicated through a Radio Resource Control (RRC) message.

In an embodiment of the present disclosure, the terminal may determine the time domain resource position occupied by the subband on the first time unit included in the terminal-specific TDD time slot structure based on the first indication information sent by the base station. The first time unit may be in units of slot, symbol or span, etc., which is not limited in the present disclosure.

For example, the terminal determines the time domain resource position occupied by the uplink subband on the downlink symbol included in the terminal-specific TDD time slot structure based on the first indication information sent by the base station.

For another example, the terminal determines the time domain resource position occupied by the downlink subband on the uplink symbol included in the terminal-specific TDD time slot structure based on the first indication information sent by the base station.

Exemplarily, the terminal-specific TDD time slot structure may include one cycle, ie, a single cycle.

Accordingly, the terminal may determine the time domain resource position occupied by the uplink subband on the downlink symbol within the single cycle indicated by the terminal-specific TDD time slot structure based on the first indication information sent by the base station. Alternatively, the terminal may determine the time domain resource position occupied by the downlink subband on the uplink symbol within the single cycle indicated by the terminal-specific TDD time slot structure based on the first indication information sent by the base station.

Exemplarily, the terminal-specific TDD time slot structure may include multiple cycles, such as a double cycle.

The first indication information can be used to indicate the time slot resource position occupied by the subband on each of the first time units included in the multiple periods, and accordingly, the terminal can determine the time domain resource position occupied by the uplink subband on all downlink symbols included in the multiple periods indicated by the terminal-specific TDD time slot structure based on the first indication information sent by the base station. Alternatively, the terminal can determine the time domain resource position occupied by the downlink subband on all uplink symbols included in the multiple periods indicated by the terminal-specific TDD time slot structure based on the first indication information sent by the base station.

The first indication information can be used to indicate the time slot resource position occupied by the subband on each of the first time units included in each of the periods, and accordingly, the terminal can determine the time domain resource position occupied by the uplink subband on all downlink symbols included in each period indicated by the terminal-specific TDD time slot structure based on the first indication information. Alternatively, the terminal can determine the time domain resource position occupied by the downlink subband on all uplink symbols included in each period indicated by the terminal-specific TDD time slot structure based on the first indication information sent by the base station.

Taking the terminal-specific TDD time slot structure including dual periods as an example, namely period P1' and period P2', illustratively, the terminal can determine the time domain resource position occupied by the uplink subband on all downlink symbols in P1' and P2' based on the first indication information. Or determine the time domain resource position occupied by the downlink subband on all uplink symbols in P1' and P2'.

Exemplarily, the terminal may determine the time domain resource positions occupied by the uplink subbands on all downlink symbols included in P1', and determine the time domain resource positions occupied by the uplink subbands on all downlink symbols included in P2' based on the first indication information.

Alternatively, the time domain resource positions occupied by the downlink subbands on all uplink symbols included in P1' are determined, and the time domain resource positions occupied by the downlink subbands on all uplink symbols included in P2' are determined.

In the above embodiment, the terminal can determine the time domain resource range occupied by the subband on the first time unit within the period indicated by the terminal-specific TDD time slot structure based on the first indication information sent by the base station, wherein the transmission direction of the first time unit is opposite to the transmission direction of the subband.

The first time unit may be in units of slot, symbol or span, etc., which is not limited in the present disclosure.

It should be noted that when the transmission direction of the first time unit is variable, that is, the first time unit is a flexible symbol or a flexible slot. When the slot is used as the unit, that is, when the first time unit includes a flexible slot, the flexible slot may include a flexible symbol, an uplink symbol and/or a downlink symbol. The transmission direction of the flexible symbol may be dynamically configured by the base station and may be configured as uplink or downlink, which is not limited in the present disclosure.

Among them, the base station side can configure a common TDD time slot structure for the terminal through the tdd-UL-DL-ConfigurationCommon carried by SIB1. In addition, the base station can configure a terminal-specific TDD time slot structure for the terminal through the tdd-UL-DL-ConfigurationDedicated carried by the RRC message.

The first time unit may be in units of slot, symbol or span, etc., which is not limited in the present disclosure.

In the disclosed embodiment, SFI indicates the TDD time slot structure at the cell level.

For example, the terminal determines the time domain resource position occupied by the uplink subband on the downlink symbol in the TDD time slot structure indicated by the SFI based on the first indication information sent by the base station.

For another example, the terminal determines the time domain resource position occupied by the downlink subband on the uplink symbol included in the TDD time slot structure indicated by the SFI based on the first indication information sent by the base station.

The transmission direction of the flexible symbol may be dynamically configured by the base station and may be configured as uplink or downlink, which is not limited in the present disclosure.

Exemplarily, the terminal determines the time domain resource positions occupied by the downlink symbol within a specified time domain range and the uplink subband on the flexible symbol based on the first indication information sent by the base station.

Exemplarily, the terminal determines the time domain resource positions occupied by the uplink symbol and the downlink subband on the flexible symbol within a specified time domain range based on the first indication information sent by the base station.

In the above embodiment, the terminal can determine the time domain resource range occupied by the subband on the first time unit within the specified time domain range based on the first indication information sent by the base station, wherein the transmission direction of the first time unit is opposite to the transmission direction of the subband, or the transmission direction of the first time unit is variable. The reliability of full-duplex communication is improved, and the availability is high.

In some optional embodiments, the first indication information may also be used to indicate the time domain resource position occupied by the subband in the first time unit. The first time unit may include: a time unit located in a specified time domain range and having a variable transmission direction.

The way in which the terminal determines the time domain resource position occupied by the subband in the first time unit based on the first indication information is similar to the way in which the time domain resource position occupied by the subband in the first time unit in the above embodiment is determined, and is not repeated here.

In some optional embodiments, the first indication information includes a resource indication value (RIV).

In the disclosed embodiment, after the value of RIV is determined, the terminal can determine the starting time domain resource position and the number of duration units corresponding to the RIV sent by the base station according to the correspondence between RIV and the starting time domain resource position and the number of duration units. The duration unit can be in units of slot, symbol or span.

Exemplarily, the time domain resource granularity indicated by the first indication information is one or more symbols, or one time slot.

The terminal may determine the time domain resource corresponding to the starting time domain resource position and the number of duration units as the time domain resource position occupied by the subband in the first time unit.

For example, the starting time domain resource position is the nth slot, the number of duration units is 2, and the time domain resource granularity indicated by the first indication information is one time slot, then the nth slot and the (n+1)th slot are determined as the time domain resource positions occupied by the subband on the first time unit.

For another example, the starting time domain resource position is the n’th symbol, the number of duration units is 2, and the time domain resource granularity indicated by the first indication information is 3 symbols, then the 6 symbols starting from the n’th symbol are determined as the time domain resource position occupied by the subband on the first time unit.

In the above embodiment, the terminal can accurately determine the time domain resource position occupied by the subband in the first time unit under any TDD time slot structure based on the RIV sent by the base station, thereby improving the reliability of full-duplex communication and high availability.

In some optional embodiments, the first indication information includes a bitmap.

The terminal may determine the time domain resource position corresponding to the bit position whose bit value in the bit map is the first bit value as the time domain resource position occupied by the subband in the first time unit.

The first bit value may be "1" or "0", which is not limited in the present disclosure.

Exemplarily, the time domain resource granularity indicated by the first indication information is one or more symbols, or one time slot.

For example, the first bit value is 1, the bit map is: 10100, and the time domain resource granularity indicated by the first indication information is 2 symbols. The terminal determines the 0th symbol, the 1st symbol, the 4th symbol, and the 5th symbol as the time domain resource positions occupied by the subband in the first time unit.

In the above embodiment, the terminal can accurately determine the time domain resource position occupied by the subband in the first time unit under any TDD time slot structure based on the bit map sent by the base station, thereby improving the reliability of full-duplex communication and high availability.

Next, the resource determination method provided by the present disclosure is introduced from the base station side.

The present disclosure provides a resource determination method, as shown in FIG2 , which is a flow chart of a resource determination method according to an embodiment, which can be performed by a base station. The method may include the following steps:

In step 201, first indication information is sent to a terminal. In the embodiment of the present disclosure, the first indication information is used to indicate the time domain resource position occupied by the subband in the first time unit.

The transmission direction of the first time unit is opposite to the transmission direction of the sub-band, or the transmission direction of the first time unit is variable. When the transmission direction of the first time unit is variable, the first time unit is a flexible symbol or a flexible slot.

The first time unit may be a SBFD time unit, wherein the SBFD time unit is a time unit on which information transmission in different transmission directions can be performed.

Exemplarily, the SBFD time unit may be a downlink time unit including an uplink subband, or a variable time unit including an uplink subband (i.e., a time unit with a variable transmission direction), or an uplink time unit including a downlink subband, or a variable time unit including a downlink subband, and the present disclosure does not limit this.

The first time unit may be a slot, a symbol, or a duration (span), etc., which is not limited in the present disclosure. A span includes multiple continuous symbols.

In the embodiment of the present disclosure, the first indication information is used to indicate the time domain resource position occupied by the subband in the first time unit.

In a possible implementation, the first indication information includes RIV.

The base station may determine the RIV based on the starting time domain resource position and the number of duration units occupied by the subband in the first time unit, and send the RIV to the terminal so that the terminal determines the time domain resource position occupied by the subband in the first time unit.

In another possible implementation manner, the first indication information may include a bit map.

Based on the time domain resource position occupied by the subband in the first time unit, in the bitmap, the bit value of the bit corresponding to the time domain resource position occupied by the subband is set to a first bit value, and the bit values of other bits are set to a second bit value. Then, the determined bitmap is sent to the terminal, so that the terminal determines the time domain resource position occupied by the subband in the first time unit based on the bitmap.

To facilitate understanding of the above scheme, the present disclosure provides the following embodiments.

In Example 1, it is assumed that the terminal is a Rel-18 or later version terminal with half-duplex capability or full-duplex capability, and this patent does not impose any limitation. For the base station, it can simultaneously send and receive data within the SBFD time unit. For the terminal, downlink data can be received within the SBFD time unit, or uplink data can be sent within the SBFD time unit. The SBFD time unit is a DL time unit including a UL subband, or a flexible time unit including a UL subband, or a UL time unit including a DL subband, or a flexible time unit including a DL subband.

In this embodiment, it is assumed that the base station configures a common TDD time slot structure for the terminal through the tdd-UL-DL-ConfigurationCommon carried in SIB1. In this embodiment, it is assumed that the base station configures a single period, that is, the TDD time slot structure has only one period (periodicity). In this embodiment, it is assumed that the TDD time slot structure is DDDDDDFFUU, where D indicates a downlink slot, F indicates a variable slot, and U indicates an uplink slot. The specific time slot structure is shown in Figure 3. Among them, slot#6 and slot#7 are flexbil slots, where slot#6 includes a downlink symbol and a flexbil symbol, and slot#7 includes a flexbil symbol and an uplink symbol.

In this embodiment, a method for determining the time domain resource position occupied by a UL subband is taken as an example. Correspondingly, the method described in this patent can also be applied to determine the time domain resource position occupied by a DL subband.

In this embodiment, it is assumed that the base station indicates the time domain resource locations occupied by UL subbands on all DL symbols within a TDD cycle indicated by a common TDD time slot structure by means of RIV or a bitmap.

Specifically, take the first indication information including RIV and bitmap as an example:

When the base station indicates the time domain resource position occupied by the UL subband on all DL symbols by means of RIV, the base station indicates the starting resource position S of the UL subband on the DL symbol and the number of continuous time domain units occupied.

The time domain resource granularity indicated by RIV may be N symbols or 1 slot, where N is a positive integer.

When the resource granularity is slot, if the time domain resource position occupied by the UL subband indicated by the RIV includes a flexible slot, the time domain resource position occupied by the UL subband in the flexible slot includes the DL symbol in the flexible slot, but does not include the flexible symbol.

When the base station indicates the time domain resource position occupied by the UL subband on all DL symbols (within a single cycle indicated by the common TDD time slot structure) by means of a bitmap, when the bit value of the bit in the bitmap is 1, it indicates that the time domain resource position occupied by the UL subband includes the time domain unit corresponding to the bit, and when the bit value of the bit is 0, it indicates that there is no UL subband on the time domain unit corresponding to the bit. The time domain resource granularity indicated by the bitmap can be N symbols, where N is a positive integer. Or the time domain resource granularity indicated by the bitmap can be 1 slot.

Embodiment 2, as described in Embodiment 1, it is assumed that the base station configures a dual-period TDD structure through tdd-UL-DL-Configuration-Common, and it is assumed that the two periods are P1 and P2. In this embodiment, it is assumed that the time slot structures of P1 and P2 are {DDF} and {DF}, respectively, and the specific time slot structure is shown in Figure 4. Among them, slot#2 and slot#4 are flexbil slots, slot#2 includes flexbil symbol and uplink symbol, and slot#4 includes flexbil symbol and uplink symbol.

In this embodiment, a method for determining the time domain resource position occupied by a UL subband is taken as an example. Correspondingly, the method described in this patent can also be applied to determine the time domain resource position occupied by a DL subband.

In this embodiment, it is assumed that the base station indicates the time domain resource position occupied by the UL subband on all DL symbols in each TDD period of the common TDD time slot structure respectively through RIV or bitmap, or indicates the time domain resource position occupied by the UL subband on all DL symbols in the two TDD periods:

Method 1: The base station indicates the time domain resource positions occupied by the UL subband on the DL symbol in P1 and P2 respectively through two RIVs or two bitmaps. The specific method is as described in Example 1 and will not be repeated here.

Method 2: The base station indicates the UL subband resource allocation on all DL symbols in P1 and P2 through a RIV or a bitmap. That is, in this embodiment, the base station indicates the time domain resource position occupied by the UL subband in three DL slots in two cycles through a RIV or a bitmap.

Embodiment 3, in this embodiment, it is assumed that the base station configures the TDD structure through tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated. It is assumed that the common TDD time slot structure is DDFFFFFFFU, and it is assumed that the terminal-specific TDD time slot structure configured by the base station for terminal #1 is DDDDDDFFFU.

In this embodiment, the base station indicates the time domain resource position occupied by the UL subband on the DL symbol in the TDD structure configured by the tdd-UL-DL-ConfigurationDedicated by means of RIV or bitmap indication.

The terminal determines the time domain resource position occupied by the UL subband on the DL symbol in the TDD structure configured by the tdd-UL-DL-ConfigurationDedicated based on the first indication information. The specific indication method is as described in Example 1 and will not be repeated here.

In this embodiment, a method for determining the time domain resource position occupied by a UL subband is taken as an example. Correspondingly, the method described in this patent can also be applied to determine the time domain resource position occupied by a DL subband.

Embodiment 4, in this embodiment, it is assumed that the base station configures the TDD time slot structure separately through tdd-UL-DL-ConfigurationCommon or configures the TDD time slot structure together through tdd-UL-DL-ConfigurationCommon and tdd-UL-DL-ConfigurationDedicated. When the base station indicates the time domain resource position occupied by the subband through RIV or bitmap, it indicates the time domain resource position occupied by the UL subband on the DL symbol and flexible symbol contained in the period indicated by the TDD time slot structure.

In this embodiment, a method for determining the time domain resource position occupied by a UL subband is taken as an example. Correspondingly, the method described in this patent can also be applied to determine the time domain resource position occupied by a DL subband.

In this embodiment, it is assumed that the base station allocates UL subband time domain resources on all DL symbols and flexible symbols within the TDD cycle through RIV or bitmap.

Specifically, take RIV and bitmap as the first indication information as examples:

When the base station indicates the time domain resource allocation of the UL subband on all DL symbols by means of RIV, the base station indicates the starting resource position S of the UL subband on the DL symbol and the number of continuous time domain units occupied. The time domain resource granularity indicated by RIV can be N symbols or 1 slot. N is a positive integer.

When the time domain resource granularity indicated by RIV is slot, if the time domain resource position occupied by the UL subband includes a flexible slot, the time domain resource position occupied by the UL subband may include both a DL symbol and a flexible symbol in the flexible slot.

When the base station indicates the time domain resource position occupied by the UL subband on all DL symbols by means of a bitmap, when the bit value of the bit in the bitmap is 1, it indicates that the time domain resource position occupied by the UL subband includes the time domain unit corresponding to the bit, otherwise it indicates that there is no UL subband on the time domain unit. The time domain resource granularity indicated by the bitmap is N symbols, where N is a positive integer.

The method of this embodiment can also be applied to a dual-cycle scenario. The specific method is as described in Example 2 and will not be repeated here.

When the base station indicates the time domain resource position occupied by the subband through RIV or bitmap, it indicates the time domain resource position occupied by the UL subband on the DL symbol within the TDD structure indicated by the SFI.

In this embodiment, a method for determining the time domain resource position occupied by a UL subband is taken as an example. Correspondingly, the method described in this patent can also be applied to determine the time domain resource position occupied by a DL subband.

In this embodiment, it is assumed that the base station allocates UL subband time domain resources for all DL symbols within the TDD cycle through RIV or bitmap.

Specifically, take RIV and bitmap as examples:

The time domain resource granularity indicated by RIV can be N symbols or 1 slot. N is a positive integer.

When the time domain resource granularity indicated by RIV is slot, if the time domain resource position occupied by the UL subband includes a flexible slot, the time domain resource position occupied by the UL subband only includes a DL symbol but does not include a flexible symbol in the flexible slot.

When the base station indicates the time domain resource position occupied by the UL subband on all DL symbols by means of a bitmap, when the bit value of the bit in the bitmap is 1, it indicates that the time domain resource position occupied by the UL subband includes the time domain unit corresponding to the bit, otherwise it indicates that there is no UL subband on the time domain unit.

In this embodiment, a method for determining the time domain resource position occupied by a UL subband is taken as an example. Correspondingly, the method described in this patent can also be applied to determine the time domain resource position occupied by a DL subband.

In this embodiment, it is assumed that the base station uses RIV or bitmap to obtain the time domain resource locations occupied by all DL symbols and flexible UL subbands within one TDD cycle.

Specifically, take RIV and bitmap as examples:

When the base station indicates the time domain resource allocation of the UL subband on all DL symbols by means of RIV, the base station indicates the starting resource position S of the UL subband on the DL symbol and the number of continuous time domain units occupied. The time domain resource granularity indicated by RIV can be N symbols or 1 slot. N is a positive integer.
