Fig. 2 is a flowchart of a method for indicating a slot format according to an embodiment of the present application. As shown in fig. 2, the slot format indication method may include, but is not limited to, the following steps:

s201, the network equipment determines first indication information, wherein the first indication information is used for indicating time slot format information and sub-band information, and the time slot format information has a corresponding relation with the sub-band information.

The slot format information may include a slot format of N slots, where N is a positive integer. Alternatively, N may be the number of slots included in one radio frame, or N is smaller than the number of slots included in one radio frame. For example, N is 1, 2, 3, 4 or other value. The slot format (e.g., first slot format, second slot format) may indicate one or more of the following: the number of downlink symbols, the number of uplink symbols, the number of flexible symbols in a certain time slot, and the link transmission direction of a certain symbol in a certain time slot. The link transmission direction of the symbol can be divided into: upstream (or denoted by "U"), downstream (or denoted by "D"), flexible (or denoted by "F"). The symbols whose link transmission direction is uplink may be simply referred to as Uplink (UL) symbols. The symbols whose link transmission direction is downlink may be simply referred to as downlink symbols, DL (downlink) symbols. Symbols with uplink or downlink transmission directions may be simply referred to as flexible symbols, F (flexible) symbols, and X symbols. The symbols in one slot may include one or more of uplink symbols, downlink symbols, and flexible symbols. By way of example, the symbol may refer to an OFDM (Orthogonal Frequency Division Multiplexing ) symbol.

The aforementioned subband information may indicate one or more subbands (subbands). For example, in an embodiment of the present application, one sub-band may occupy one or more PRBs (physical resource block, physical resource blocks) in the frequency domain. The one or more subbands indicated by the subband information may be included in one carrier or may be included in one BWP (Bandwidth Part). Wherein the carrier is a carrier supported by the terminal device, the carrier is, for example, a CC (component carrier, carrier unit), and the BWP is a BWP supported by the terminal device. For example, one carrier may be configured with one or more subbands, and the size (size, or referred to as bandwidth) of the one or more subbands may be the same or different. For another example, one or more subbands may be allocated to one BWP, and the size of the one or more subbands may be the same or different. Alternatively, one or more BWPs may be allocated to one carrier.

The meaning of the corresponding relation between the time slot format information and the sub-band information is that: the slot format indicated by the slot format information may be applied to the sub-band indicated by the sub-band information, or the slot format of the sub-band indicated by the sub-band information is the slot format indicated by the slot format information.

For example, the content indicated by the first indication information may be further described as: the first indication information is used for indicating the time slot format information and the sub-band information corresponding to the time slot format information, or the first indication information is used for indicating the sub-band information and the time slot format information corresponding to the sub-band information. The "subband information corresponding to the timeslot format information" refers to a frequency domain position where the timeslot format information is applied, where granularity of the frequency domain position is a certain subband or a certain subbands. For example, taking a subband applied in the slot format of the network device indicating the slot 1 to the terminal device as subband 1, the "subband applied in the slot format of the slot 1 is subband 1" indicates: the terminal device may transmit data or receive data using sub-band 1 in time slot 1, and correspondingly, the network device may receive data from the terminal device using sub-band 1 in time slot 1, or the network device may transmit data to the terminal device using sub-band 1 in time slot 1. The "slot format information corresponding to the subband information" means that the slot format of the subband indicated by the subband information is indicated by the slot format information.

As can be seen from the above, the first indication information can configure the sub-band-level slot format for the terminal device. Compared with the configuration of the same time slot format for all frequency domain resources of one carrier wave at the same time, the embodiment of the application can enable the configuration of the time slot format to be more flexible by configuring the time slot format of the sub-band level for the terminal equipment, and is beneficial to better matching the requirements of different services.

For example, taking a radio frame including 10 slots (slots) and a carrier including 3 subbands, the 3 subbands are respectively exemplified by subband 0, subband 1, and subband 2, fig. 3 is a schematic diagram of configuring the same slot format for all frequency domain resources of a carrier at the same time, and fig. 4 is 4 kinds of schematic diagrams of configuring slot formats of a subband level for a terminal device. In fig. 3 and 4, gray filled boxes indicate time slots (or symbols) with downlink transmission directions, grid filled boxes indicate time slots (or symbols) with uplink transmission directions, and diagonal filled boxes indicate time slots (or symbols) with uplink or downlink transmission directions. It should be noted that the link transmission directions of all symbols in one slot shown in fig. 3 and fig. 4 are the same for illustration, and the embodiment of the present application is not limited to this, and in a specific implementation, one or more of an uplink symbol, a downlink symbol, and a flexible symbol may be included in one slot.

As shown in fig. 3, the slot format of each sub-band is: in the embodiment of the present application, the letter D, F, U may be used to indicate that the link transmission direction is downlink, uplink, or uplink time slots (or symbols), respectively. The slot format of each sub-band is the same (i.e. the link transmission direction of each sub-band is the same at the same time), which means that the terminal device can only perform uplink transmission or downlink transmission at the same time. Along with diversification of services, different services have different uplink and downlink transmission requirements, and the same time slot format is configured at the same time aiming at different frequency domain resources of the same carrier, so that the requirements of different services cannot be met.

As shown in 4 diagrams in fig. 4, the slot formats of different sub-bands may be different (i.e., the link transmission directions of different sub-bands at the same time may be the same), so that uplink transmission and downlink transmission may be performed on different sub-bands of the same carrier at the same time. For example, in the first diagram of fig. 4, downlink transmission is possible in both the sub-band 0 and the sub-band 2 in the time slots 0 to 2, and uplink transmission is possible in the sub-band 1 in the time slots 0 to 2. For a TDD (Time Division Duplexing, time division duplex) system, full duplex of the sub-bands can be achieved in this way, that is, uplink transmission and downlink transmission can be performed simultaneously on the same carrier at the same time.

S202, the network equipment sends the first indication information to the terminal equipment. Correspondingly, the terminal equipment receives the first indication information.

The network device determines first indication information and then transmits the first indication information to the terminal device. Alternatively, the first indication information may be carried in higher layer signaling or DCI (Downlink Control Information ). For example, the higher layer signaling may be RRC (Radio Resource Control ) signaling.

S203, the terminal equipment determines the time slot format information and the sub-band information according to the first indication information.

The terminal device receives the first indication information, and according to the first indication information, can determine the time slot format information and the sub-band information corresponding to the time slot format information, or can determine the sub-band information and the time slot format information corresponding to the sub-band information.

By implementing the embodiment of the application, the first indication information can be used for configuring the sub-band-level time slot format for the terminal equipment. Compared with the configuration of the same time slot format for all frequency domain resources of one carrier wave at the same time, the embodiment of the application can enable the configuration of the time slot format to be more flexible by configuring the time slot format of the sub-band level for the terminal equipment, and is beneficial to better matching the requirements of different services.

The network device configuration slot format may take any of the following 3 ways:

configuration mode 1: the network equipment configures a cell-level time slot format, wherein the cell-level time slot format is that the pointers adopt the same time slot format for time domain resources corresponding to a certain cell. For example, if the time domain resource corresponding to cell a includes 3 carriers, the cell-level slot format configured for cell a is applicable to the 3 carriers. Alternatively, the network device may send RRC (Radio Resource Control ) signaling to the terminal device, which may configure the cell-level slot format.

Configuration mode 2: firstly, the network equipment adopts a configuration mode 1 to configure a cell-level time slot format, and then configures a UE-level time slot format on the basis of the configured cell-level time slot format. The UE-level slot format is configured for one or some UEs within the cell by the pointer, while the cell-level slot format is configured for all UEs within the cell. Alternatively, the network device may send UE-specific signaling to the terminal device, which may configure the UE-level slot format.

Configuration mode 3: firstly, the network equipment adopts a configuration mode 2 to sequentially configure a cell-level time slot format and a UE-level time slot format, and then configures a dynamic time slot format on the basis of configuring the UE-level time slot format. The dynamic slot format may indicate a slot format of one or more slots (slots) on one or more carriers. Alternatively, the network device may send a PDCCH (Physical Downlink Control Channel ) to a set of terminal devices, where the DCI carried on the PDCCH may include an SFI (slot format indication ) for indicating the slot format of one or more slots (slots) on one or more carriers.

The configuration of the cell-level time slot format by the network device in the configuration mode 1 comprises the following steps: the cell-level slot format is configured by pattern 1, and optionally, by both pattern 1 and pattern 2. Wherein, the time slot configuration period of the pattern 1 is P milliseconds (ms), and the time slot configuration period of the pattern 2 is P2 ms. The following information is contained in both pattern 1 and pattern 2: the number of downlink timeslots (with d _slots Indicated), descendingThe number of downlink symbols after the slot (with d _sym Indicated), number of uplink time slots (indicated by u _slots Indicated), number of uplink symbols before uplink slot (indicated by u _sym Representation). D in pattern 1 and pattern 2 _slots 、d _sym 、u _slots 、u _sym The values of (2) may be different. By way of example, with P being 10ms and one slot being 1ms, a schematic diagram of pattern 1 for a network device configuration may be shown in fig. 5. Taking P as 4ms, P2 as 6ms, and one slot as 1ms as an example, a schematic diagram of pattern 1 and pattern 2 configured by the network device may be shown in fig. 6.

The UE-level slot format resets only the flexible symbols at the cell level without modifying the DL or UL symbols at the cell level. The network device configuring the UE-level slot format in configuration mode 2 includes: for each slot, one of the following three indications is selected for UE-level slot format configuration: indication 1: the network device configures each symbol in the slot as a downlink symbol (if symbols=allrowlink, all symbols in the slot are downlink). Indication 2: the network device configures each symbol in the slot as an uplink symbol (if symbols=alluplink, all symbols in the slot are uplink). Indication 3: the network device indicates that the first few symbols in the slot are reset to DL symbols by parameter 1 (nrofDownlinkSymbols) in the UE-specific signaling and the last few symbols in the slot are reset to UL symbols by parameter 2 (nrofUplinkSymbols) in the UE-specific signaling, the remaining symbols in the slot being flexible symbols. If the UE-specific signaling does not carry parameter 1 (nrofDownlinkSymbols), then the first symbol in the slot is not a DL symbol, if the UE-specific signaling does not carry parameter 2 (nrofUplinkSymbols), then the last symbol in the slot is not a UL symbol, and the remaining symbols in the slot are flexible symbols. As noted above, the UE-level slot format may be configured for each slot. It should be noted that, the process of configuring the slot format by the network device is: firstly, the network device configures a certain symbol as an uplink symbol, a downlink symbol or a flexible symbol, and then the network device sends indication information (such as first indication information, second indication information (see below)) to the terminal device, and the terminal device can know which type of the symbol is the uplink symbol, the downlink symbol or the flexible symbol according to the indication information. In the embodiment of the application, the terminal equipment can correspondingly acquire the content configured by the network equipment according to the content configured by the network equipment or acquire the content configured by the network equipment according to the content acquired by the terminal equipment based on the indication information.

Fig. 7 is a schematic diagram of a UE-level slot format further configured by the network device based on the cell-level slot format configured by pattern 1 (as shown in fig. 5). As can be seen from fig. 5 and fig. 7, the network device configures the UE-level slot format, specifically, configures all symbols in the slot 3 as downlink symbols, configures the first few symbols in the slot 4 as downlink symbols, and configures the last few symbols in the slot 5 as uplink symbols. The configuration of the other slots is the same as the cell-level slot format configuration.

The network device configuring the dynamic time slot format in the configuration mode 3 comprises: the network equipment sends SFI to the terminal equipment, and after the terminal equipment monitors the SFI, the index information indicated by the SFI is obtained, and the dynamic time slot format is determined according to the index information. Wherein the index information is an index in a UE-specific table. The terminal equipment determines a dynamic time slot format according to the index information, and the method comprises the following steps: the terminal device takes the time slot format information corresponding to the index information in the UE special table as a dynamic time slot format.

Wherein the UE-specific table may include one or more rows of data, each row of data may include: an index, and a set of slot formats (or referred to as a slot format information combination) corresponding to the index, the set of slot formats may be combined from one or more "single slot formats". The "single slot format" is used to indicate the link transmission direction of each symbol in one slot.

Alternatively, all "single slot formats" supported by the communication system may be collectively represented by a slot format. Illustratively, taking the communication system supporting 14 "single slot formats" as an example, the total table of slot formats may be as shown in table 1. Each row in table 1 represents a slot format table, one slot format table representing a "single slot format", and a slot format index is used to indicate a "single slot format". The 14 slot format tables form the slot format summary table of table 1. In each slot format table, 0 to 13 represent indexes of symbols in a slot, D represents a downlink symbol, U represents an uplink symbol, and X represents a flexible symbol (or denoted as F). It should be noted that, table 1 takes 14 symbols in one slot as an example, and does not limit the embodiments of the present application, and in other implementations, the number of symbols in one slot may also be other values.

Table 1 time slot format summary

It should be noted that, table 1 is taken as an example of supporting 14 "single slot formats" by the communication system, and is not limited to this embodiment of the present application, in a specific implementation, the communication system may support more "single slot formats", for example, the number of "single slot formats" supported in the NR system may be 256, 512 or other numbers, which are not listed here for brevity.

The set of slot formats in each row of data in the UE-specific table may be one or more slot format indexes in table 1 above, one slot format index corresponding to one "single slot format" (i.e., one slot format index corresponding to one slot format table in table 1). Illustratively, the UE-specific table may be as shown in table 2.

Table 2UE specific tables

Index	Set of slot formats (orTime slot format information combination
		0	Slot format index (0), slot format index (1), …
1	Slot format index (1), slot format index (2), …
		2	Slot format index (3), slot format index (10), …
…	…

In table 2, the number in parentheses after each slot format index in the slot format set is the value of the slot format index in table 1. For example, slot format index (0) represents "single slot format" corresponding to slot format index 0 in table 1, slot format index (1) represents "single slot format" corresponding to slot format index 1 in table 1, slot format index (2) represents "single slot format" corresponding to slot format index 2 in table 1, and so on.

Optionally, the plurality of slot format indexes listed in sequence in the slot format set are indexes of slot formats of each of the N slots in sequence. For example, a first slot format index in the set of slot formats is an index of a slot format of a first slot of the N slots, a second slot format index is an index of a slot format of a second slot of the N slots, a third slot format index is an index of a slot format of a third slot of the N slots, and so on.

In one implementation, the slot format information in S201 may include a first slot format of N slots. The Slot Formats (SF) referred to in the embodiments of the present application may include a first slot format, which is a slot format indicated by first indication information, and a second slot format (see below), which is a slot format indicated by second indication information. The slot formats (e.g., first slot format, second slot format) of the different slots may be the same or different.

In one implementation, before step S201, the slot format indication method may further include: the network equipment sends second indication information to the terminal equipment, wherein the second indication information is used for indicating a second time slot format of M time slots, and the M time slots comprise the N time slots; the first indication information is specifically configured to indicate that the slot formats of the N slots are reconfigured from the second slot format to the first slot format. M is a positive integer greater than or equal to N.

Alternatively, the second indication information may be used to configure a cell-level slot format, and at this time, the first indication information may be used to configure a UE-level slot format or a dynamic slot format. In the case that the first indication information is used to configure the UE-level slot format, the first indication information may be carried in UE-specific signaling. The UE-specific signaling may be carried in higher layer signaling (e.g., RRC (Radio Resource Control, radio resource control) signaling). UE-specific signaling may also be referred to as UE-specific signaling. In the case that the first indication information is used to configure the dynamic slot format, the first indication information may be carried in DCI.

Optionally, each of the N time slots may include a flexible symbol, that is, the first indication information specifically configures a link transmission direction of the flexible symbol (or the flexible time slot) to be uplink or downlink, and does not change a configuration of an uplink symbol and a downlink symbol in the cell level configuration.

In one implementation, the slot format information in S201 may include a first slot format of N slots, the sub-band information in S201 may indicate one or more sub-bands, the first slot format of each slot may have a correspondence with one or more sub-bands in the sub-band information, or the first slot format of each slot may have a correspondence with some or all sub-bands in the sub-band information.

Wherein, the expression that the first time slot format of one time slot has a corresponding relation with one sub-band in the sub-band information is as follows: the first slot format configured for one slot is applied to one subband, i.e. no subbands are transformed in that slot. For example, a schematic diagram of "a first slot format of one slot has a correspondence with one subband" may be seen in fig. 8, where in fig. 8, gray filled boxes indicate slots (or symbols) with downlink transmission directions, and grid filled boxes indicate slots (or symbols) with uplink transmission directions. In fig. 8, the first slot format of each of slots 0-4 corresponds to one subband (i.e., subband 0), and the first slot format of each of slots 5-9 corresponds to one subband (i.e., subband 1). Optionally, the N time slots include a first time slot; the first slot format of the first slot may be used to indicate a link transmission direction of symbols within the first slot; the link transmission direction of each symbol in the first time slot is the same, and the first time slot format of the first time slot has a corresponding relation with one sub-band in the sub-band information. In other words, in the case where the link transmission directions of symbols in a certain slot (e.g., the first slot) are all the same direction, the first slot format of the slot is applied to one subband. For example, the first time slot may be any of the time slots in fig. 8.

"the first slot format of one slot has a correspondence relationship with a plurality of subbands in the subband information" means: the first slot format configured for one slot applies to multiple subbands, i.e., there is a subband switch within the slot. The first slot format configured for one slot is a slot format configured for symbols within the slot, and "the first slot format configured for one slot is applied to a plurality of subbands" may mean that: the subbands applied for the first slot format configured for a portion of the symbols in one slot may be different from the subbands applied for the first slot format configured for another portion of the slot. Optionally, the N time slots include a second time slot; the first slot format of the second slot is used for indicating the link transmission direction of the symbols in the second slot; the link transmission directions of at least two symbols in the second time slot are different, and the first time slot format of the second time slot has a corresponding relation with one or more sub-bands in the sub-band information. For example, a schematic diagram of "the first slot format of one slot has a correspondence with a plurality of subbands in the subband information" may be seen in fig. 9, where in fig. 9, a gray filled square indicates a slot (or symbol) with a downlink transmission direction, and a grid filled square indicates a slot (or symbol) with an uplink transmission direction. In fig. 9, the first 7 symbols in slot 4 correspond to the same subband (i.e., symbols 0-6 correspond to subband 0), the last 7 symbols in slot 4 correspond to another subband (i.e., symbols 7-13 correspond to subband 1), instant 4 corresponds to two subbands, and there is a subband switch in slot 4 (switch from subband 0 to subband 1).

In one implementation manner, the N time slots include a second time slot, where the second time slot includes a first symbol and a second symbol, and a link transmission direction of the first symbol is different from a link transmission direction of the second symbol; the sub-band having a correspondence with the first slot format of the second slot includes: the sub-band having a correspondence with the first symbol and the sub-band having a correspondence with the second symbol are different from the sub-band having a correspondence with the first symbol and the sub-band having a correspondence with the second symbol. In other words, symbols with different link transmission directions correspond to different subbands. For example, in fig. 9, the link transmission directions of symbols 0 to 6 are different from those of symbols 7 to 13, the subbands corresponding to symbols 0 to 6 are different from those corresponding to symbols 7 to 13, symbols 0 to 6 correspond to subband 0, and symbols 7 to 13 correspond to subband 1. Wherein the number of the first symbols and the second symbols can be one or more. The link transmission directions of the first symbol and the second symbol can be uplink or downlink. For example, the first symbol includes symbols 0 to 6 in fig. 9, and the second symbol includes symbols 7 to 13 in fig. 9.

In one implementation, a network device may configure a sub-band level slot format for one or more terminal devices. Illustratively, taking the example of the network device configuring the slot formats of the sub-band level for terminal device 1 and terminal device 2, the network device may send UE-specific signaling 1 to terminal device 1 and UE-specific signaling 2 to terminal device 2. Wherein the UE-specific signaling 1 is used for configuring the subband-level slot format for the terminal device 1, and the UE-specific signaling 2 is used for configuring the subband-level slot format for the terminal device 2. The slot format of the subband level configured for the terminal device 1 may be the same as or different from the slot format of the subband level configured for the terminal device 2, which is not limited in the embodiment of the present application. It should be noted that, the terminal devices may not know the sub-band-level slot format configured by the network device for other terminal devices, for example, the terminal device 1 does not know the sub-band-level slot format configured by the network device for the terminal device 2. It should be further noted that, in the case that one carrier includes a plurality of subbands, the terminal device only knows the timeslot format information, the subband information, and the correspondence between the timeslot format information and the subband information indicated by the network device through the first indication information. For example, in fig. 8, although the terminal device may use the sub-band 0 and the sub-band 1, it is only known to the terminal device that the sub-band 0 can be used for downlink transmission in the time slots 0 to 4 and the sub-band 1 can be used for uplink transmission in the time slots 5 to 9.

In one implementation, the foregoing first indication information may include: a first index for indicating the slot format information and a second index for indicating the subband information; wherein the first index corresponds to a first set, and the first set includes a first slot format of the N slots; the second index corresponds to a second set comprising N groups of subband indexes, each group of subband indexes having a correspondence with a first slot format of one of the N slots, each group of subband indexes comprising indexes of one or more subbands.

The first set may be included in the UE-specific table (e.g., as shown in table 2), and the first set may be one set of slot formats in the UE-specific table, that is, the first set is one line of data in the UE-specific table. The first index is an index in a UE-specific table. For example, one set of slot formats in table 2 includes N slot format indexes, one slot format index being an index of a first slot format of one of the N slots in the slot format total table shown in table 1.

The second set may be contained in a subband index table. The subband index table may comprise one or more sets of subband indices, the second set being one of the subband index sets, the second index being an index in the subband index table. Illustratively, the subband index table may be as shown in table 3.

Table 3 subband index table

In table 3, the number in brackets after each subband index in the set of subband indices is the index of the subband or subbands. For example, subband index (0) represents a subband with an index value of 0 (i.e., subband 0), subband index (1) represents a subband with an index value of 1 (i.e., subband 1), subband index (2) represents a subband with an index value of 2 (i.e., subband 2), and so on. Wherein the subband index (0, 1) represents subband 0 and subband 1.

It will be appreciated that one slot format index in the first set has a relationship to a set of subband indices in the second set. Illustratively, taking the first set as the timeslot format set corresponding to the index 2 in table 2, and the second set as the subband index set corresponding to the index 2 in table 3 as an example, where "timeslot format index (3)" corresponds to "subband index (1)", and "timeslot format index (10)" corresponds to "subband index (0, 1)", …. The meaning of the "slot format index (3)" corresponding to the "subband index (1)" is: the index of the slot format of the first slot of the N slots is 3 and the slot format of the first slot is applied to subband 1. The meaning of the "slot format index (10)" corresponding to the "subband index (0, 1)" is: the index of the slot format of the second slot of the N slots is 10, and the slot format of the second slot is applied to the sub-band 0 and the sub-band 1, and the "single slot format" corresponding to the slot format index of 10 in table 1 (symbol 0 is a downlink symbol, symbol 13 is an uplink symbol, and the remaining symbols are flexible symbols) can be known that the downlink transmission can be performed through the sub-band 0 on the symbol 0 of the second slot, and the uplink transmission can be performed through the sub-band 1 on the symbol 13 of the second slot.

Alternatively, the first index may be indicated by a slot format field, and the second index may be indicated by a subband index field added in DCI. For example, a subband index field is added in DCI format 2_0.

In one implementation, the first indication information includes: a third index indicating the slot format information and the subband information; the third index corresponds to a third set, and the third set includes N groups of information, where each group of information includes a first slot format of one slot of the N slots and a subband index having a correspondence with the first slot format of the one slot. The number of subband indexes corresponding to the first slot format of the one slot may be one or more, and if there are a plurality of subband indexes, the subband indexes indicate that the subband is switched in the slot. The third set may be included in a joint indication table, which may include one or more joint indication sets, one of which is the third set, and the third index is an index in the joint indication table. The joint indication table may be as shown in table 4.

Table 4 joint indication table

Index	Joint indication set
		0	Slot format index (0) and subband index (0), slot format index (1) and subband index (1), …
1	Slot format index (1) and subband index (1), slot format index (2) and subband index (2), …
		2	Slot format index (3) and subband index (1), slot format index (10) and subband index (0, 1), …
…	…

The joint indication table may be understood as a combination of a UE-specific table and a subband index table. One set of joint indications in the joint indication table may be: one set of slot formats in the UE-specific table is combined with one set of subband indices in the subband index table.

Alternatively, the third index may be indicated by a slot format field. In this way, the first indication information can be indicated to the terminal device without extending other fields.

It should be noted that, the first indication information is used to configure the timeslot format of the sub-band level for the terminal device for example, and in other implementations, the first indication information may be used to configure the timeslot format of the BWP (Bandwidth Part) level for the terminal device, that is, the first indication information is used to indicate timeslot format information and BWP information, where the timeslot format information has a corresponding relationship with the BWP information. In this way the granularity of the frequency domain location where the slot format information is applied is some BWP or some BWP. Or in other implementations, the first indication information may also configure a slot format with other granularity for the terminal device, which is not limited in the embodiment of the present application.
