In some embodiments, the time units in the embodiments of the present disclosure may be in units of slots (slots), orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbols, and duration (span), which is not limited by the present disclosure. Wherein a span comprises a plurality of consecutive symbols.

In some embodiments, the first time unit may be defined as a sub-band full duplex (SBFD) time unit, such as that shown in fig. 2B.

In some embodiments, the present disclosure does not limit the name of the first time unit.

In some embodiments, the transmission direction of the first time unit is flexible, and the network device configures a first sub-band on the first time unit whose transmission direction is flexible, where the first sub-band may be an uplink sub-band or a downlink sub-band.

Illustratively, if the network device 102 configures the uplink sub-band for the terminal 101 at a first time unit whose transmission direction is flexible, the terminal 101 may perform uplink transmission within a frequency domain range of the uplink sub-band of the first time unit.

Illustratively, if the network device 102 configures the downlink sub-band for the terminal 101 at a first time unit whose transmission direction is flexible, the terminal 101 may perform downlink transmission in a frequency domain range of the downlink sub-band of the first time unit.

In some embodiments, the transmission direction of the first time unit is opposite to the first sub-band, e.g. the network device 102 configures the terminal 101 with an uplink sub-band on a DownLink (DL) time unit.

Accordingly, the terminal 101 may perform uplink transmission in an uplink sub-band range of the downlink time unit, or the terminal 101 may perform downlink transmission in other frequency domain ranges of the downlink time unit.

In some embodiments, the transmission direction of the first time unit is opposite to the first sub-band, e.g. the network device 102 configures the terminal 101 with a downlink sub-band on an UpLink (UL) time unit.

Accordingly, the terminal 101 may perform downlink transmission in the downlink sub-band range of the uplink time unit. Or the terminal 101 may perform uplink transmission in other frequency domain ranges of the downlink time unit.

In some embodiments, the network device 102 may indicate, in a semi-static or dynamic manner, the time-division multiplexing upstream and downstream configuration currently employed by the terminal (TDD UL DL configuration).

Illustratively, the network device 102 may configure the semi-static TDD UL DL configuration via system messages, such as system information blocks (System Information Block, SIBs) and/or radio resource control signaling (Radio Resource Control signaling, RRC signaling). The base station configures the time division multiplexing uplink and downlink configuration of the cell level through the high-layer signaling.

And in the period of the base station configuration, the base station configures the positions and the number of the downlink time units, the flexible time units and the uplink time units.

Illustratively, the network device 102 may dynamically indicate the uplink and downlink structures of one or more slots through a slot format indicator (Slot Format Indicator, SFI) carried by downlink control information (Downlink Control Information, DCI) format 2_0 (format 2_0).

Based on the current TDD UL-DL configuration, a certain transition time is required between DL and UL, ensuring that the terminal 101 has sufficient advance and switching time. On the other hand, also ensures that the network device 102 has enough time to perform a handover of a received transmission. For the switching time between UL and DL, it can be guaranteed by the advanced transmission of the terminal 101.

TDD UL DL configuration is applied to the entire operating bandwidth, either in a semi-static configuration or in a dynamic indication. That is, when there are both uplink resources and downlink resources in one slot, for example, in the SBFD slot, it is necessary to determine the time domain range in which the terminal switches the transmission direction.

For example, as shown in fig. 2C, for terminal 101, it may perform a downlink to uplink handover based on the scheduling of network device 102. When the network device 102 schedules the terminal 101 to perform transmission in different transmission directions on the adjacent SBFD slots, the terminal 101 needs a certain switching time, for example, as shown in fig. 2D, which may result in that part of the symbols cannot be used for data transmission.

Both the terminal 101 and the network device 102 need to define a switching point, i.e. a time domain range in which the terminal switches the transmission direction, at which the terminal 101 performs switching of the transmission direction, and at which the network device 102 does not perform data scheduling, avoiding wasting network signaling resources.

In step S2101, the terminal 101 transmits capability information to the network device 102.

In some embodiments, the network device 102 receives the capability information.

In some embodiments, the capability information is used to indicate a first transmission configuration supported by the terminal 101.

The first transmission configuration refers to, for example, a transmission configuration that the terminal 101 is capable of supporting when communicating with the network device 102 in a first time unit or first subband.

The first transmission configuration is applied to the first time unit described above, which may be an SBFD time unit, for example.

The first transmission configuration is applied to the first subband described above, which may be an uplink subband or a downlink subband within the SBFD time unit, for example.

In some embodiments, the capability information may be used to indicate a first configuration of the number of switching points within the time window.

The time window may be, for example, a contiguous range of time domain resources.

Illustratively, the at least one first time unit is included within the time window.

For example, since a certain period of time is required when the terminal 101 switches the transmission direction, the switching point may be a time domain range in which the terminal 101 switches the transmission direction.

Illustratively, the handover point may also be referred to as an uplink-downlink handover point, which is a time domain range in which the terminal 101 switches from downlink to uplink or from uplink to downlink.

Illustratively, the terminal 101 informs the network device 102 of the first configuration of the number of switching points it supports within a time window via the capability information.

In some embodiments, the capability information is used to indicate a first length of a supported time window.

Illustratively, the time window includes at least one first time unit therein.

Illustratively, the time window includes a range of the first sub-band in the time domain, as shown in fig. 2E, where the first sub-band occupies slots #0 to #2, and each of slots #0 to #2 in the time window is a first time unit, that is, an SBFD time unit.

Illustratively, the time window includes a plurality of time units included in one time division multiplexing configuration period.

Illustratively, the network device 102 configures the TDD UL-DL configuration to determine a time division multiplexing configuration period including at least one first time unit therein, e.g., as shown in fig. 2F, the time window including slots #0 through #4, wherein slots #1 through #3 are the first time units.

Illustratively, the time window includes a first number of time units that are contiguous in the time domain. At least one of the first time units is included in the first number of time units.

For example, as shown in fig. 2G, the time window includes slots #0 to #9, where slots #1 to #3, and slots #6 to #8 are first time units.

Wherein the first number and start time units of the time window may be agreed upon by the protocol or configured by the network device 102, which is not limited by the present disclosure. In some embodiments, the capability information is used to indicate a maximum number of handover points supported within a time window. In one example, the maximum number may be a non-negative integer.

Illustratively, if the terminal 101 does not expect to switch transmission directions within the time window, the maximum number of switching points supported within the time window indicated by the capability information is 0.

Illustratively, the terminal 101 supports switching of the transmission direction within the time window, and the maximum number of switching points supported within the time window indicated by the capability information may be a positive integer, for example, 1, 2, 3, … ….

The maximum number of candidate values may be configured by the network device 102 for the terminal 101, for example, the candidate value set includes {0,1, 2 … … } among which the terminal 101 selects one according to its own capabilities to send to the network device 102.

The maximum number of candidate values may be agreed upon by the protocol, for example, the set of candidate values includes {0,1, 2 … … }, among which the terminal 101 selects one to send to the network device 102.

In one example, if the first sub-band satisfies the first condition or the first time unit satisfies the first condition, the maximum number of handover points supported within the time window indicated by the capability information may be 0.

The first condition may be that the terminal 101 does not support transmission direction switching on the first sub-band or the first time unit, or that the terminal 101 needs to perform a service specifying a transmission direction, or other conditions, for example.

Illustratively, the maximum number of switching points supported by the terminal 101 within the time window is 0, and the bit value indicated by the capability information may be "000".

Illustratively, when the maximum number of switching points supported by the terminal 101 in the time window is in the range of 0-5, the bit value indicated by the capability information may be "110" or "111" when the terminal 101 determines that the maximum number of switching points supported in the time window is 0.

Illustratively, when the maximum number of switching points supported by the terminal 101 in the time window is in the range of 0-5, the bit values of the capability information are "110" and "111", it may be used to indicate other information, such as a transmission direction, whether the switching points are supported in one of the first time units, and so on.

In some embodiments, the capability information is used to indicate the number of time units associated with the handover point that are supported.

In one example, the switching point is a time domain range in which the terminal 101 switches transmission directions.

In one example, the number of time units may include a minimum number of time units of adjacent two of the switch point intervals.

The minimum number of time units between two adjacent switching points may be N OFDM symbols or M slots, and N, M is a non-negative integer.

Illustratively, the network device 102 may configure a plurality of candidate values of the minimum number of time units of the two adjacent switching point intervals, and the terminal 101 selects one of the candidate values according to its own capability to report to the network device 102.

Illustratively, the protocol may agree on a plurality of candidate values of the minimum number of time units of the two adjacent switching point intervals, and the terminal 101 selects one of the candidate values to report to the network device 102 according to its own capability.

In one example, the number of time units may include a minimum number of time units that are continuously transmitted in at least one transmission direction.

Illustratively, the transmission direction includes, but is not limited to, upstream, downstream.

The minimum number of time units of the uplink persistent transmission and the minimum number of units of the downlink persistent transmission may be equal or unequal, which is not limited in the present disclosure.

For example, the network device 102 may configure a plurality of candidate values of the minimum number of time units continuously transmitted in at least one transmission direction, and the terminal 101 selects one of the candidate values to report to the network device 102 according to its own capability.

Illustratively, the protocol may agree on a plurality of candidate values for the minimum number of time units to be continuously transmitted in at least one transmission direction, and the terminal 101 selects one of the candidate values to report to the network device 102 according to its own capabilities.

In one example, the number of time units may include a minimum number of time units of adjacent two of the switch point intervals, and a minimum number of time units continuously transmitted in at least one transmission direction.

For example, the manner in which the capability information indicates the number of time units may be similar to the manner in which the capability information indicates the maximum number of switching points supported in the time window, which is not described herein.

In one example, the number of time units may also include other numbers, which are not limited by the present disclosure.

In some embodiments, capability information is used to indicate time units supporting the existence of a switch point within the time window.

In one example, at least one of the first time units is included in a time window.

In one example, the switching point is a time domain range in which the terminal switches transmission directions.

Illustratively, the terminal 101 may indicate, in a bit map (bitmap) manner, the time units supporting the existence of a switch point within the time window.

For example, there are N time units within the time window, and the capability information occupies N bits, each bit being used to indicate whether a switching point exists for one time unit within the time window. Assuming a bit value of 1010 for the N bits, the terminal may determine that the first time cell, the third time cell, support the existence of a handoff point.

For another example, there are N time units in the time window, and the capability information occupies N/2 bits, each bit being used to indicate whether or not there are switching points for two adjacent time units in the time window. Assuming that the bit value of the N bits is 1010, the terminal may determine that the first time unit, the second time unit, the fifth time unit, and the sixth time unit support the existence of a handoff point. The above is merely an exemplary illustration, and the granularity of the capability information indication may be greater, as this disclosure is not limited in this regard.

In some embodiments, the capability information is used to indicate the length of time required for the supported switch transmission direction.

In one example, the duration required to switch the transmission direction refers to the minimum number of time units that the terminal needs to occupy to switch from uplink to downlink or from downlink to uplink.

The minimum number of time units may be a positive integer.

In some embodiments, capability information is used to indicate whether the presence of the switch point within one of the first time units is supported.

In one example, the terminal may indicate whether the presence of the handover point in one of the first time units is supported by 1 bit.

Illustratively, a bit value of "1" for capability information is used to indicate that the switch point is supported to exist within one of the first time units.

Illustratively, a bit value of "0" for capability information is used to indicate that the presence of the switch point within one of the first time units is not supported.

Vice versa, no further description is given here.

In some embodiments, capability information is used to indicate two or more of the above, which is not limiting of the present disclosure.

For example, when the capability information is used to indicate two or more of the above items, it may be indicated sequentially in a preset order, e.g. from the most significant bit (Most Significant Bit, MSB) to the least significant bit (Least Significant Bit, LSB) may indicate sequentially the first configuration of the number of handover points in the time window, the first length of the supported time window, the maximum number of handover points supported in the time window, the number of time units supported in association with the handover points, the time units in the time window where the handover points are supported, the duration required for supporting the direction of the handover transmission, whether the handover points are supported in one of said first time units.

In some embodiments, the capability information is used to indicate other information related to the transmission configuration supported by the terminal, which is not limited by the present disclosure.

In step S2102, the network device 102 configures a transmission configuration for the terminal 101.

In some embodiments, the network device 102 may determine the first transmission configuration supported by the terminal 101 based on the capability information.

Illustratively, the network device 102 may determine, based on the capability information, a first configuration of the number of handover points of the terminal 101 within a time window, a first length of a supported time window, a maximum number of supported handover points within the time window, a number of supported time units associated with a handover point, a supported time unit in which a handover point exists, a supported time required for switching the transmission direction, and whether one or more of the handover points exist within one of the first time units is supported, depending on the content of the capability information.

Illustratively, if the maximum number of handover points supported by the terminal within the time window indicated by the capability information is 0, the network device 102 may determine that the first sub-band satisfies the first condition or that the first time unit satisfies the first condition.

The first condition may be that the terminal 101 does not support transmission direction switching on the first sub-band or the first time unit, or that the terminal 101 needs to perform a service specifying a transmission direction, or other conditions, for example.

In some embodiments, the network device 102 configures a second transmission configuration for the terminal based on the capability information.

In one example, the second transmission configuration information is below a first threshold determined by the network device 102 based on the capability information.

Wherein the third transmission configuration is not dependent on the capability information sent by the terminal 101.

The foregoing is merely exemplary, and all schemes in which the network device 102 configures the transmission configuration for the terminal 101 are within the scope of the present disclosure.

The terminal 101 may illustratively communicate with the network device 102 on a first sub-band or first time unit based on the second transmission configuration.

In step S2105, the terminal 101 does not expect to switch the transmission direction again in the time window after the number of times of switching the transmission direction in the time window reaches the first number.

In some embodiments, the terminal 101 receives a third transmission configuration, wherein the number of switching points indicated by the third transmission configuration within a time window is greater than the maximum number of switching points supported within the time window indicated by the first transmission configuration.

In some embodiments, the first number of times is equal to the maximum number of terminal transmissions through the capability information.

In some embodiments, after the number of times the terminal switches the transmission direction in the time window reaches the first number, the terminal does not expect to switch the transmission direction again in the time window. Illustratively, the terminal does not expect to perform transmission direction switching.

In some embodiments, the maximum number of switching points supported by the terminal 101 within a time window is 0, within which the terminal 101 does not expect to switch transmission directions.

In the above embodiment, the network device configures transmission configuration for the terminal based on the capability information, so that the complexity of terminal control is reduced, and the feasibility and availability of full duplex communication are improved.

The foregoing schemes provided for the embodiments of the present disclosure are further illustrated below.

Terminal side:

a full duplex terminal, for example, an SBFD aware (SBFD aware) terminal, reports its own capability to the network side for supporting the number of uplink and downlink handover points, where the terminal capability at least includes one of the following:

1. reporting the time window length by the terminal;

2. the maximum number of uplink and downlink switching points supported by the terminal in the time window;

if the maximum number reported by the terminal is 0, the terminal does not expect uplink and downlink switching in the time window;

wherein the maximum number has a plurality of candidate values, and is an integer greater than or equal to 0;

3. the minimum distance between two adjacent uplink and downlink switching points supported by the terminal;

for example, N OFDM symbols or M slots;

4. a time domain pattern (pattern) of the switching points within a time window;

for example, slots or symbols existing at uplink and downlink switching points;

5. the switching time length supported by the terminal;

the switching time comprises C candidate values, wherein C is an integer greater than or equal to 1;

6. a minimum time for UL transmission or DL reception to last;

wherein the time comprises a plurality of candidate values;

7. Whether the terminal supports an SBFD slot memory at the uplink and downlink switching points.

Network equipment side:

and the network equipment side receives the terminal capacity of the number of the uplink and downlink switching points in the time window, reported by the terminal, determines a scheduling strategy in the time window according to the related terminal capacity, and ensures that the number and the position of the uplink and downlink switching points in the time window do not exceed the terminal capacity.

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 network device performs full duplex operation, i.e. simultaneously schedules downlink data and uplink data, in downlink time slots of a time division duplex (Time Division Duplexing, TDD) band. The network device performs full duplex operation in one of the following manners, which is not limited in this patent:

the frequency domain resources for DL transmission and UL transmission within a DL slot are independent of each other and do not overlap with each other, as shown in fig. 5A;

the frequency domain resources for DL transmission and UL transmission within a DL slot are fully coincident, as shown in fig. 5B;

the frequency domain resources within the DL slot for DL transmission and UL transmission partially coincide, as shown in fig. 5C.

In this embodiment, the network device informs the terminal of the number of uplink and downlink switching points existing in a certain time range through an indication signaling. The switch points are used for switching between downlink to uplink (DL-to-UL) and/or uplink to downlink (UL-to-DL). The time required for uplink and downlink switching is not limited in this patent.

In this embodiment, it is assumed that the frame structure is DDDSU, where D represents downlink, S represents flexible, U represents uplink, and the network device configures uplink subbands (UL subbands) for uplink data transmission in the second, third, and fourth slots for the terminal. The network device may schedule or configure the terminal to send uplink or receive downlink on the SBFD slot according to the service requirement. Once the transmission direction is changed, a certain switching time is required between uplink and downlink, as shown in fig. 2C.

In this embodiment, the terminal reports its own capability for the number of uplink and downlink switching points to the network device. The capability reflects the number of uplink and downlink switching points in the continuous SBFD slot that the terminal can support.

In this embodiment, the terminal reports at least one or any combination of the following capabilities to the network device, which is not limited in this patent:

1. The length of the reporting time window of the terminal;

wherein, the length of the reporting time window may have a plurality of candidate values, including but not limited to:

a TDD period;

UL subband duration time frame;

s OFDM symbols or slots;

2. the maximum number of uplink and downlink switching points supported by the terminal in the time window;

if the maximum number reported by the terminal is 0, the terminal does not expect uplink and downlink switching in the time window;

wherein the maximum number has a plurality of candidate values, and is an integer greater than or equal to 0;

3. the minimum distance between two adjacent uplink and downlink switching points supported by the terminal;

for example, N OFDM symbols or M slots;

4. time domain pattern of the switching point in the time window;

for example, slots or symbols existing at uplink and downlink switching points;

5. the switching time length supported by the terminal;

wherein the switching time comprises C candidate values, and C is an integer greater than or equal to 1;

6. a minimum time for UL transmission or DL reception to last;

wherein the time comprises a plurality of candidate values;

7. whether the terminal supports an SBFD slot memory at the uplink and downlink switching points.

After receiving the terminal capability reported by the terminal, the network device performs data scheduling on the continuous SBFD slots according to the terminal capability, or indicates the transmission of related reference signals, or configures a semi-static data channel.

For example, if the terminal reports that the number of uplink and downlink switching points supported in the time window is M and the switching time is S, the base station should ensure that the number of switching points does not exceed M and should ensure that the distance between DL and UL is greater than or equal to S when configuring or scheduling related transmissions for the terminal.

Embodiment 2, as described in embodiment 1, assumes that the terminal has reported to the network device the terminal capability with respect to the number of uplink and downlink handover points.

If the scheduling or configuration of the network device results in the number of up-down transition points exceeding the terminal capability within the time window, the behavior of the terminal is unpredictable. The specific method of operation depends on the terminal side implementation and the protocol does not make any provisions.

In the above embodiment, the network device configures the number of switching points for the terminal based on the capability information reported by the terminal, thereby reducing the control complexity of the terminal and improving the feasibility and availability of full duplex communication.
