The full duplex scheme is studied in Release-18, rel-18 full duplex enhancement (duplex enhancement) project, specifically, the base station can transmit and receive data simultaneously in one slot (slot).

For TDD carriers, there are currently a variety of TDD slot structures including, but not limited to, the following:

a single period TDD slot structure configured by a common TDD-UL-DL-configuration common;

a dual-period TDD time slot structure configured by TDD-UL-DL-configurationCommon;

TDD slot structure configured by TDD-UL-DL-configuration command and dedicated TDD configuration (TDD-UL-DL-configuration configured);

Currently, there are few specific schemes how to implement the indication of subband time domain resources under the above-mentioned different TDD slot structures.

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

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

An embodiment of the present disclosure provides a method for determining resources, referring to fig. 1, fig. 1 is a flowchart of a method for determining resources, which may be performed by a terminal, and the method may include the following steps:

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

In an embodiment of the present disclosure, the first indication information is used to indicate a time domain resource location occupied by the subband on the first time unit.

Wherein the first time unit may be a seamless bi-directional forwarding detection (Seamless Bidirectional Forwarding Detection, SBFD) time unit. The SBFD time unit is a time unit on which information transmission with different transmission directions can be performed.

The SBFD time unit may be a downlink time unit including an uplink sub-band, or a variable time unit including an uplink sub-band (i.e., a time unit whose transmission direction is variable), or an uplink time unit including a downlink sub-band, or a variable time unit including a downlink sub-band, which is not limited in this disclosure.

The first time unit may be in a slot, symbol, or duration (span), which is not limited in this disclosure. Wherein a span comprises a plurality of consecutive symbols.

In step 102, the time domain resource location occupied by the sub-band on the first time unit is determined based on the first indication information.

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

In one possible implementation, the first indication information comprises a RIV. After the value of the RIV is determined, the terminal can determine the initial time domain resource position and the duration time unit number corresponding to the RIV sent by the base station according to the corresponding relation between the RIV and the initial time domain resource position and the duration time unit number. Determining the time domain resource position occupied by a sub-band on the first time unit based on a starting time domain resource position and a duration unit number.

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

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

In some alternative embodiments, the first indication information is used to indicate a time domain resource location occupied by the subband over 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 a transmission direction of the subband.

In the embodiment of the present disclosure, the common TDD slot structure may be a TDD slot structure that can be commonly used by a plurality of terminals configured for the terminal by the base station side through TDD-UL-DL-configuration communication. The base station side may carry the tdd-UL-DL-configuration command through a system information block1 (System Information Block, SIB 1).

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

For example, the terminal determines, based on the first indication information sent by the base station, a time domain resource location occupied by an uplink sub-band on a downlink symbol in the common TDD slot structure.

For another example, the terminal determines, based on the first indication information sent by the base station, a time domain resource location occupied by a downlink sub-band on an uplink symbol included in the common TDD slot structure.

Illustratively, the common TDD slot structure may include one period, i.e., a single period.

Correspondingly, the terminal can determine the time domain resource position occupied by the uplink sub-band on the downlink symbol in the single period indicated by the public TDD time slot structure based on the first indication information sent by the base station. Or, the terminal may determine, based on the first indication information sent by the base station, a time domain resource location occupied by a downlink sub-band on an uplink symbol in a single period indicated by the common TDD slot structure.

Illustratively, the common TDD slot structure may include multiple periods, e.g., dual periods.

The first indication information may be used to indicate the time slot resource location occupied by the subband in each of the first time units in the multiple periods, and accordingly, the terminal may determine, based on the first indication information sent by the base station, a time domain resource location occupied by the uplink subband on all downlink symbols in the multiple periods indicated by the common TDD time slot structure. Or, the terminal may determine, based on the first indication information sent by the base station, a time domain resource location occupied by downlink subbands on all uplink symbols included in a plurality of periods indicated by the common TDD slot structure.

Or when the first indication information is used for indicating the time slot resource positions occupied by the sub-bands on each first time unit included in each period in a plurality of periods, the terminal can respectively determine the time domain resource positions occupied by the uplink sub-bands on all downlink symbols included in each period indicated by the common TDD time slot structure based on the first indication information. Or, the terminal may determine, based on the first indication information sent by the base station, the time domain resource positions occupied by the downlink subbands on all uplink symbols included in each period indicated by the common TDD slot structure.

Taking the example that the common TDD slot structure includes dual periods, i.e., period P1 and period P2, respectively, the terminal may determine, based on the first indication information, a time domain resource location occupied by the uplink sub-bands on all downlink symbols in P1 and P2. Or determining the time domain resource positions occupied by the downlink sub-bands on all uplink symbols included in P1 and P2.

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

Or determining the time domain resource positions occupied by the downlink sub-bands on all uplink symbols included in the P1, and determining the time domain resource positions occupied by the downlink sub-bands on all uplink symbols included in the P2.

Of course, the first indication information sent by the base station may only indicate the time domain resource position occupied by the sub-band on the first time unit in P1 or P2, and the terminal correspondingly determines the time domain resource position occupied by the sub-band on the first time unit in P1 or P2 based on the first indication information.

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

In some alternative embodiments, the first indication information is used to indicate a time domain resource location occupied by the subband over 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 a transmission direction of the subband.

The terminal-specific TDD slot structure may be a terminal-specific TDD slot structure configured by the base station side for the terminal through TDD-UL-DL-configuration. The base station side may carry the tdd-UL-DL-configuration defined through a radio resource control (Radio Resource Control, RRC) message.

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

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

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

For example, the terminal-specific TDD slot structure may include one period, i.e., a single period.

Correspondingly, the terminal can determine the time domain resource position occupied by the uplink sub-band on the downlink symbol in the single period indicated by the special TDD time slot structure of the terminal based on the first indication information sent by the base station. Or, the terminal may determine, based on the first indication information sent by the base station, a time domain resource location occupied by a downlink sub-band on an uplink symbol in a single period indicated by the terminal-specific TDD slot structure.

Illustratively, the terminal-specific TDD slot structure may include multiple periods, e.g., dual periods.

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

The first indication information may be used to indicate the time slot resource positions occupied by the sub-bands on each of the first time units included in each of the periods, and accordingly, the terminal may determine, based on the first indication information, time domain resource positions occupied by the uplink sub-bands on all of the downlink symbols included in each of the periods indicated by the terminal-specific TDD time slot structure, respectively. Or, the terminal may determine, based on the first indication information sent by the base station, the time domain resource positions occupied by the downlink subbands on all uplink symbols included in each period indicated by the terminal-specific TDD slot structure.

Taking the example that the TDD slot structure dedicated for the terminal includes a dual period, which is period P1 'and period P2', respectively, the terminal may determine, for example, based on the first indication information, the time domain resource positions occupied by the uplink subbands on all the downlink symbols in P1 'and P2'. Or determining the time domain resource positions occupied by the downlink sub-bands on all the uplink symbols in P1 'and P2'.

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

Or determining the time domain resource positions occupied by the downlink sub-bands on all uplink symbols included in the P1', and determining the time domain resource positions occupied by the downlink sub-bands on all uplink symbols included in the P2'.

In the above embodiment, the terminal may determine, based on the first indication information sent by the base station, a time domain resource range occupied by the sub-band located on the first time unit in the period indicated by the terminal-specific TDD time slot structure, where a transmission direction of the first time unit is opposite to a transmission direction of the sub-band.

The first time unit may be in slot, symbol, span, or the like, which is not limited in this disclosure.

When the slot is taken as a unit, that is, when the first time unit includes a flexible slot, flexible symbol, uplink symbol and/or downlink symbol may be included in the flexible slot. 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 this disclosure.

Illustratively, the common TDD slot structure and/or the terminal-specific TDD slot structure may include a single period or multiple periods, which is not limited by the present disclosure.

In the above embodiment, the terminal may determine, based on the first indication information sent by the base station, a time domain resource range occupied by the sub-band located on the first time unit in the period indicated by the first TDD time slot structure, where a transmission direction of the first time unit is opposite to a transmission direction of the sub-band or a transmission direction of the first time unit is variable.

Wherein the first time unit comprises: time units located within the period of the TDD slot structure indicated by the slot format indicator (Slot Format Indication, SFI) and having a transmission direction opposite to that of the sub-band.

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

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

When the base station indicates the time domain resource position occupied by the UL sub-band on all DL symbols by means of a bitmap, the time domain resource position occupied by the UL sub-band is indicated to contain the time domain unit corresponding to the bit position when the bit value of the bit position in the bitmap is 1, otherwise, the time domain unit does not exist the UL sub-band.
