[0066] The resource determination method and device provided by the embodiments of the present application will be described in detail below in combination with the accompanying drawings and some embodiments and application scenarios.
[0067] In a communication system, a network configures a BWP and / or a carrier for a terminal to perform data transmission. The bandwidth of the terminal can dynamically change.
[0068] Figure 2 A BWP configuration schematic diagram provided by the embodiments of the present application is as follows, Figure 2As shown, at the first time, the terminal has a large amount of traffic, and the system configures a large bandwidth (BWP1) for the terminal; at the second time, the terminal has a small amount of traffic, and the system configures a small bandwidth (BWP2) for the terminal, which can meet the basic communication requirements; at the third time, the system finds that there is a large range of frequency selective fading in the bandwidth of BWP1, or the resources in the frequency range of BWP1 are relatively scarce, and then configures a new bandwidth (BWP3) for the terminal.
[0069] Each BWP is not only different in frequency point and bandwidth, but also can correspond to different configurations. For example, the subcarrier spacing, CP type, SSB (PSS / SSS PBCH Block) period of each BWP can be configured differently to adapt to different services.
[0070] The technical advantages of BWP mainly have four aspects:
[0071] 1. The terminal does not need to support the entire bandwidth, but only needs to meet the minimum bandwidth requirement, which is beneficial to the development of low-cost terminals;
[0072] 2. When the terminal traffic is not large, the terminal can switch to low-bandwidth operation, which can significantly reduce power consumption;
[0073] 3. Communication technology is forward compatible, and when new technology is added to the communication system, the new technology can be directly run on the new BWP, ensuring the forward compatibility of the system;
[0074] 4. Adapt to business needs and dynamically configure BWP for business.
[0075] In addition, in the communication system, the uplink and downlink configuration can be symbol-based, and the configuration is more flexible. The specific configuration process is as follows:
[0076] (1) First, configure the cell semi-static uplink and downlink configuration;
[0077] The high layer provides a parameter TDD-UL-DL-ConfigurationCommon, which contains a reference subcarrier spacing u (reference SCS configuration) and a pattern1, and the pattern1 contains:
[0078] Slot configuration period P ms;
[0079] Number of downlink slots Dslots (number of slots with only downlink symbols);
[0080] Dsym (number of downlink symbols);
[0081] Uslots (number of slots with only uplink symbols);
[0082] Usym (number of uplink symbols);
[0083] Where the configuration period P = 0.625ms is valid only for 120kHz subcarrier spacing, P = 1.25ms is valid only for 60 and 120kHz subcarrier spacing, P = 2.5ms is valid only for 30 60 and 120kHz subcarrier spacing. Then one configuration period can be known how many slots it contains by the formula S = P * 2u. In these slots, the first Dslots slots are downlink slots, followed by Dsym downlink symbols, followed by Usym uplink symbols, and finally Uslots uplink slots. After the uplink and downlink are configured in the S slots, the remaining is the flexible symbol X.
[0084] If the parameter is given both pattern1 and pattern2, two different slot formats can be configured continuously, and the parameter form in pattern2 is similar to pattern1.
[0085] (2) Then configure cell-specific uplink and downlink configuration;
[0086] If the high-level parameter TDD-UL-DL-ConfigDedicated is further provided on the basis of the configuration in (1), the parameter can configure the flexible symbol configured by the parameter TDD-UL-DL-ConfigurationCommon. That is, the uplink and downlink symbols configured in (1) cannot be changed, but the flexible symbol can be overwritten by TDD-UL-DL-ConfigDedicated.
[0087] This parameter provides a series of slot configurations, for each slot configuration, provides slot index and symbol configuration, for the slot specified by slot index, where:
[0088] If symbols = allDownlink, all symbols in the slot are downlink;
[0089] If symbols = allUplink, all symbols in the slot are uplink;
[0090] If symbols = explicit, the parameter nrofDownlinkSymbols first provides the number of downlink symbols;
[0091] That is, if explicit, the parameter nrofDownlinkSymbols provides the number of downlink symbols, nrofUplinkSymbols provides the number of uplink symbols, the downlink symbols are in the front, and the uplink symbols are in the rear, if the parameter nrofDownlinkSymbols is not provided, there is no downlink symbol, if nrofUplinkSymbols is not provided, there is no uplink symbol. After the configuration, if there is a remainder, the remaining symbols are still flexible symbols X. The reference subcarrier spacing reference SCS configuration in (2) is the same as in (1).
[0092] The uplink and downlink configuration realized by dynamic DCI is realized by DCI format 2-0, or directly realized by uplink and downlink data scheduling of DCI format 0-0 0-1 1-0 1-1. DCI format 2-0 is specially used as SFI indication. SFI mainly realizes periodic frame structure configuration according to the slot format that can be supported by a single slot, that is, from receiving DCI format 2-0, the slot is configured according to the time domain format indication information (slot format indicator, SFI) in the downlink control information (Downlink Control Information, DCI) for PDCCH monitoring period slots. The maximum number of formats supported by a single slot is 256, and the standardized format is 56. The slot format table of normal cp is shown in Table 1 (slot format table of normal cyclic prefix);

[0123] Optionally, the terminal determines a target transmission direction corresponding to each of the at least one sub-band based on the frequency domain format indication information.

[0135] Bandwidth part size Configuration 1 Configuration 2 1–36 2 4 37–72 4 8 73–144 8 16 145–275 16 16
[0136] Optionally, the frequency domain format indication information comprises: at least one second indication information corresponding to the at least one sub-band.
[0137] The target transmission direction of the at least one sub-band is indicated by the second indication information based on the sub-band frequency of the at least one sub-band from low to high or from high to low.
[0138] Figure 4 is one of the schematic diagrams of the resource determination method provided by the embodiments of the present application, as shown in Figure 4 The target transmission direction of the at least one sub-band is indicated by the second indication information based on the sub-band frequency of the at least one sub-band from low to high or from high to low; that is, the FFI can indicate from the low frequency to the high frequency direction of the sub-band, or vice versa, which can be configured by the network side device.
[0139] For example, the FFI is "DDFFFUUD", from the low frequency to the high frequency direction of the sub-band, the first sub-band is the DL downlink direction, the second sub-band is the DL downlink direction, the third sub-band is the flexible direction, the fourth sub-band is the flexible direction, the fifth sub-band is the flexible direction, the sixth sub-band is the UL uplink direction, the seventh sub-band is the UL uplink direction, and the eighth sub-band is the DL downlink transmission.
[0140] Optionally, Figure 5 is the second schematic diagram of the resource determination method provided by the embodiments of the present application, as shown in Figure 5 The network side device can configure at least one flexible sub-band for each carrier or each bwp through the frequency domain format indication information, and when indicated again through the frequency domain format indication information FFI, only the flexible sub-band can be changed. Other sub-bands are not allowed to change. The complexity and signaling overhead of indication can be reduced.
[0141] Optionally, the size of the frequency domain format indication information is determined based on the number of the at least one sub-band.

[0143] For example, if the sub-band size is the same as the RBG size, it is determined by the BWP bandwidth. One BWP size is 128 RBs, and if one sub-band is configured as 16 RBs. Then a total of 8 sub-bands need to be indicated by the FFI to indicate the transmission direction, and the bitmap indication method can be used. If there are D, U, and F three states, then each sub-band needs 2 bits, and a total of 16 bits are needed to represent the transmission direction of 8 sub-bands.

The frequency domain format indication information includes: the reference transmission direction indication information, and the number and location of the flexible subbands.

[0146] Optionally, in order to reduce signaling overhead, for a BWP, the network side device can semi-statically configure or indicate the frequency domain reference transmission direction at a time or some times, and the number M of flexible subbands and the location of the flexible subbands.
[0147] Optionally, the network side device can indicate that the reference direction is a downlink direction DL or an uplink direction UL.
[0148] Optionally, for a BWP reference transmission direction as DL or UL, the network side device can be configured with K subbands as flexible subbands; then the transmission direction of the subbands other than the K flexible subbands is the downlink direction DL or the uplink direction UL.
[0149] Optionally, the terminal determines the target transmission direction of each of the at least one subband in a frequency domain resource unit based on the frequency domain format indication information, including:
[0150] The terminal determines the target transmission direction of the flexible subband in the at least one subband and the non-flexible subband in the at least one subband based on the reference direction indication information, wherein the non-flexible subband is a subband in the at least one subband that is not a flexible subband.
[0151] Optionally, the network side device can indicate that the reference direction is a downlink direction DL or an uplink direction UL, and then it can be determined that the transmission direction of the subbands other than the flexible subbands is the downlink direction DL or the uplink direction UL.
[0152] Optionally, the network side device can subsequently change only the direction of the flexible subbands, for example, one FFI indicates that the flexible subband N is changed to an uplink or downlink direction, and the unindicated subbands (M-N) are determined according to the reference transmission direction.
[0153] Optionally, the network side device can subsequently change only the direction of the flexible subbands, for example, one FFI indicates that the flexible subband N is changed to an uplink or downlink direction, and the unindicated flexible subbands (O-N) are determined according to the reference transmission direction.
[0154] For example, if the terminal receives the frequency domain format indication information again, the transmission direction referenced by BWP is DL. The network-side device is configured with L sub-bands as flexible sub-bands. The frequency domain format indication information FFI can indicate the number and position of the L flexible sub-bands used as UL sub-bands. The remaining flexible sub-bands that are not indicated can be used as the reference transmission direction, i.e., DL.
[0155] Optionally, the network side can also be configured such that, apart from L subbands, the other subbands in the flexible subband remain in the flexible direction.

[0159] Optionally, the size of the frequency domain format indication information is determined based on the number of flexible sub-bands, and the transmission direction of other sub-bands is indicated by a semi-static network side.
[0160] For example, network-side devices use a continuous resource indication method to indicate the frequency domain formats of D, U, and F, on a sub-band basis. When the frequency domain format indication information includes: reference direction indication information, and the number and location of the flexible sub-bands, respectively... The bit indicates the frequency domain resources of D, U, and F.
[0161] Alternatively, if the higher-level configuration of FFI can only instruct flexbile resources to change the transmission direction, then signaling overhead can be saved.

For carrier 2, the UE is configured to have 3 BWPs, which are BWP1, BWP2, and BWP3.

[0351] Optionally, the terminal can determine the size of each subband and the number of the at least one subband when dividing one frequency domain unit into multiple subbands based on the first indication information sent by the network side device.

[0353] Table 2 sub-band size configuration table
[0354] Bandwidth part size Configuration 1 Configuration 2 1–36 2 4 37–72 4 8 73–144 8 16 145–275 16 16
[0355] Optionally, the frequency domain format indication information comprises: at least one second indication information corresponding to the at least one sub-band.
[0356] Optionally, the target transmission direction of the at least one sub-band is indicated by the second indication information based on the sub-band frequency of the at least one sub-band from low to high or from high to low.
[0357] Optionally, as shown in the following table, the target transmission direction of the at least one sub-band is indicated by the second indication information based on the sub-band frequency of the at least one sub-band from low to high or from high to low; that is, the FFI can be configured by the network side device from the direction of the low frequency to the high frequency of the sub-band, or vice versa. Figure 4
[0358] For example, if the FFI is "DDFFFUUD", from the direction of the low frequency to the high frequency of the sub-band, the first sub-band is in the DL downlink direction, the second sub-band is in the DL downlink direction, the third sub-band is in the flexible direction, the fourth sub-band is in the flexible direction, the fifth sub-band is in the flexible direction, the sixth sub-band is in the UL uplink direction, the seventh sub-band is in the UL uplink direction, and the eighth sub-band is in the DL downlink direction.
[0359] Optionally, as shown in the following table, the network side device can configure at least one flexible sub-band for each carrier or each bwp through the frequency domain format indication information, and only the flexible sub-band can be changed when indicated again through the frequency domain format indication information FFI. Other sub-bands cannot be changed. The complexity and signaling overhead of indication can be reduced. Figure 5
[0360] Optionally, the size of the frequency domain format indication information is determined based on the number of the at least one sub-band.
[0361] Optionally, in the case where the target transmission direction of the at least one sub-band is indicated by the second indication information based on the sub-band frequency of the at least one sub-band from low to high or from high to low, the size of the frequency domain format indication information is determined based on the number of the at least one sub-band.
[0362] For example, if the sub-band size is the same as the RBG size, which is determined by the BWP bandwidth. If one BWP size is 128 RBs and one sub-band is configured to be 16 RBs. Then a total of 8 sub-bands need to be indicated by the FFI to indicate the transmission direction, and the bitmap indication method can be used. If there are D, U, and F three states, then each sub-band needs 2 bits, and a total of 16 bits are needed to represent the transmission direction of 8 sub-bands.
[0363] Optionally, the network can semi-statically indicate the transmission direction of some subbands as UL or DL. The remaining flexible subbands are indicated by FFI. The frequency domain format indication information includes: reference direction indication information, the number and location of the flexible subbands.
[0364] Optionally, the frequency domain format indication information includes: reference direction indication information, and the number and location of the flexible subbands.
[0365] Optionally, in order to reduce signaling overhead, for a BWP, the network side device can semi-statically configure or indicate the frequency domain reference transmission direction at a time or some times, and the number M of flexible subbands and the location of the flexible subbands.
[0366] Optionally, the network side device can indicate that the reference direction is the downlink direction DL or the uplink direction UL.
[0367] Optionally, for a BWP, the reference transmission direction is DL or UL, and the network side device can be configured with K subbands as flexible subbands; then the transmission direction of the subbands other than the K flexible subbands is the downlink direction DL or the uplink direction UL.
[0368] Optionally, the network side device can indicate that the reference direction is the downlink direction DL or the uplink direction UL, and it can be determined that the transmission direction of the subbands other than the flexible subbands is the downlink direction DL or the uplink direction UL.
[0369] Optionally, the network side device can subsequently change only the direction of the flexible subbands, for example, one FFI indicates that the flexible subband N is changed to the uplink or downlink direction, and the transmission direction of the unindicated subbands (M-N) is determined according to the reference transmission direction.
[0370] Optionally, the network side device can subsequently change only the direction of the flexible subbands, for example, one FFI indicates that the flexible subband N is changed to the uplink or downlink direction, and the transmission direction of the unindicated flexible subbands (O-N) is determined according to the reference transmission direction.
[0371] For example, if the terminal receives the frequency domain format indication information again, at this time the BWP reference transmission direction is DL, the network side device is configured with L subbands as flexible subbands, and the frequency domain format indication information FFI can indicate the number and location of the L flexible subbands used as UL subbands, and the remaining flexible subbands can be the reference transmission direction, i.e. DL.
[0372] Optionally, the network side device can also configure that, in addition to the L subbands, the other subbands in the flexible subbands remain unchanged in the flexible direction.
[0373] Optionally, the network-side device can indicate that the FFI can be indicated semi-statically by high-layer signaling or MAC CE or dynamically by DCI.
[0374] Optionally, the network-side device can first configure the subband size.
[0375] Optionally, the network-side device can configure a reference subband size according to a different SCS, and other subbands are calculated according to the subcarrier spacing of the corresponding BWP or carrier, the reference subcarrier spacing, and the reference subband size.
[0376] Optionally, the size of the frequency domain format indication information is determined based on the number of flexible subbands, and the transmission direction of other subbands is semi-statically indicated by the network side.
[0377] For example, the network-side device uses a continuous resource indication method in units of subbands to indicate the frequency domain format of D, U, and F. In the case where the frequency domain format indication information includes reference direction indication information, the number and location of flexible subbands, respectively, bit indicates the frequency domain resource of D, U, and F.
[0378] Optionally, if the high layer configures the FFI to only indicate that the flexible resource changes the transmission direction, the signaling overhead can be saved.
[0379] Optionally, as Figure 6 indicated, the reference direction is DL, and the FFI indicates that the flexible resource changes to UL transmission direction, the remaining F subbands are in the DL direction. If the transmission direction of the 5 flexible subbands is indicated in the form of bitmap, then 5 bits are required.
[0380] Optionally, the reference transmission direction, i.e., the reference direction indication information, can also be indicated by SFI.
[0381] Optionally, the reference transmission direction, i.e., the reference direction indication information, can also be network-configured.
[0382] Optionally, the frequency domain format indication information includes a first index; the first index is used to indicate a first target format group in a first frequency domain format table; each first target format group in the first frequency domain format table includes each subband and a target transmission direction corresponding to the each subband.
[0383] The first frequency domain format table is pre-configured or pre-defined by a protocol or pre-indicated by the network-side device.
[0384] Optionally, the system can be pre-configured or the protocol can be pre-defined or the network side device can be pre-instructed an index table for FFI indication, i.e., a first frequency domain format table, including at least one first index and a first target format group corresponding to each first index, wherein each first target format group can indicate a target transmission direction corresponding to all subbands in a carrier or a BWP.
[0385] Optionally, in the case that the terminal knows the first frequency domain format table, the network side device can send the first index to the terminal, and the network side device can indicate the transmission direction of all subbands in the target carrier or BWP by indicating the first index.
[0386] Optionally, in the case that the terminal knows the first frequency domain format table, the terminal can receive the first index sent by the network side device, and determine the first target format group corresponding to the first index in the first frequency domain format table through the first index, and further determine the indication content corresponding to the first target format group, i.e., the transmission direction of all subbands in the target carrier or BWP.
[0387] Optionally, for all subbands n of a carrier or a BWP, the network can configure an n-column table.
[0388] Taking 8 subbands as an example, Table 3 can be a first frequency domain format table, and the transmission direction of all subbands can be indicated by indicating an index.
[0389] Table 3 first frequency domain format table
[0390]
[0391] It should be noted that Table 3 is only an example of the first frequency domain format table and does not limit the first frequency domain format table.
[0392] Optionally, the first subband to the seventh subband can be determined in the order from low frequency to high frequency or in the order from high frequency to low frequency in all subbands in a BWP or a carrier.
[0393] For example, if the first index included in the frequency domain format indication information is 3, i.e., the first subband to the seventh subband is “DFFUUUUU”, the terminal can determine that in the order from low frequency to high frequency, the first subband is in the DL downlink direction, the second subband is in the flexible direction, the third subband is in the flexible direction, the fourth subband is in the UL uplink direction, the fifth subband is in the UL uplink direction, the sixth subband is in the UL uplink direction, and the seventh subband is in the UL uplink direction.
[0394] Optionally, the network side device sending the frequency domain format indication information includes:
[0395] The network side device sends at least one frequency domain format indication information;
[0396] In this context, one frequency domain format indication information corresponds to one frequency domain resource unit, and different frequency domain format indication information corresponds to different frequency domain resource units.
[0397] Optionally, a frequency domain resource element can be at least one carrier or at least one BWP.
[0398] Optionally, an FFI location can be configured in the DCI for each carrier or each BWP, indicating the target transmission direction for all subbands in each carrier or each BWP.
[0399] Optionally, such as Figure 7 As shown, a DCI carrying FFI can contain FFIs of multiple carriers.
[0400] Optionally, when a frequency domain format indication information corresponds to an indication of a carrier, all BWPs in a carrier can use the same FFI; for example, the first BWP in carrier 1 has 7 sub-bands and the second BWP has 7 sub-bands; the FFI indicates that the target transmission direction of the 7 sub-bands in the first BWP is "UUFFUDD" and the target transmission direction of the 7 sub-bands in the second BWP is also "UUFFUDD".
[0401] Optionally, such as Figure 8 As shown, the DCI carrying FFI can contain FFIs of multiple BWPs; for example, BWP1 has 8 subbands, BWP2 has 8 subbands, BWP3 has 8 subbands, ..., BWP n has 8 subbands; FFI1 indicates "UUFFUDDU", FFI2 indicates "UDFFUDUU", FFI3 indicates "UFFFFDUU", ..., FFI n indicates "UFDFFDUU"; the terminal can determine the target transmission direction of the 8 subbands as "UUFFUDDU" based on FFI1 indicating BWP1; the terminal can determine the target transmission direction of the 8 subbands as "UFFFFDUU" based on FFI2 indicating BWP2; the terminal can determine the target transmission direction of the 8 subbands as "UFFFFDUU" based on FFI3 indicating BWP3; ...; the terminal can determine the target transmission direction of the 8 subbands as "UFDFFDUU" based on FFI n indicating BWP n.
[0402] Optionally, when the network-side device simultaneously indicates multiple frequency domain format indication information, each frequency domain format indication information can correspond to a terminal group, and different terminals (groups) can use the same or different frequency domain format indicated by the frequency domain format indication information.
[0403] Optionally, the location of the FFI for each terminal group can be configured in the DCI. For example, for a UE, the network configures the FFI of BWP1 and BWP2 of the UE in the DCI as FFI1 and FFI2.
[0404] For example, reference can also be made to Figure 8 When the UE is configured to use BWP1, the UE uses FFI1, i.e., the target transmission direction of the 8 subbands can be determined as "UU FF UDDU", and when the UE uses BWP2, the UE uses FFI2.
[0405] Optionally, as Figure 9 indicated, the network side device can also jointly indicate the FFI of each bwp and each carrier for a terminal group.
[0406] For example, the UE is configured to be a carrier aggregation of 2 carriers, for carrier 1, the UE is configured with 3 BWPs, BWP1, BWP2, and BWP3. For carrier 2, the UE is configured with 3 BWPs, BWP1, BWP2, and BWP3. When the UE is configured with BWP1 of carrier 1 and BWP3 of carrier 2, the UE will determine the frequency domain format according to FFI1 and FFI6.
[0407] Optionally, the frequency domain format indication information includes a third index group;
[0408] The third index group is used to indicate at least one third target format group in a third frequency domain format table, wherein each third target format group corresponds to indicating a subband respectively;
[0409] Each third target format group is used to indicate the target transmission direction corresponding to each sub-slot in the time domain resource unit;
[0410] The third frequency domain format table is pre-configured or protocol pre-defined or pre-indicated by the network side device to the terminal.
[0411] Optionally, the system can pre-configure or the protocol can pre-define or the network side device can pre-indicate an index table for FFI indication, i.e., a third frequency domain format table, including at least one third index eSFI index n and a third target format group corresponding to each third index, wherein each third target format group can correspond to indicating the target transmission direction corresponding to each sub-slot in the time domain unit corresponding to a subband.
[0412] Optionally, in the case where the terminal knows the third frequency domain format table, the network side device can send the third index group to the terminal, and the network side device can indicate the target transmission direction corresponding to each sub-slot in each time domain unit corresponding to all subbands of the target carrier or BWP by indicating the third index group.
[0413] Optionally, in the case that the terminal knows the third frequency domain format table, the terminal can receive the third index sent by the network side device, and determine the third target format group corresponding to the third index in the third frequency domain format table through the third index, and further determine the indication content corresponding to the third target format group, i.e., the target transmission direction corresponding to each sub-slot in the time domain unit corresponding to the target carrier or BWP all sub-bands.
[0414] Optionally, as shown in Figure 10 for example, one BWP includes 6 sub-bands, i.e., sub-band 1 to sub-band 6, and one time domain unit includes 6 sub-slots; i.e., the network side device can indicate that sub-band 1 to sub-band 6 correspond to third index groups eSFI1, eSFI2, …, eSFI6 respectively, wherein eSFI1 can indicate that the target transmission direction of each time domain unit of the first sub-band is “DDDDDD”, eSFI2 can indicate that the target transmission direction of each time domain unit of the second sub-band is “DFUUUU”, …, and eSFI6 indicates that the target transmission direction of each time domain unit of the sixth sub-band is “DUFDDD”.
[0415] Optionally, the third target format groups corresponding to different sub-bands in one BWP or one carrier can be the same or different;
[0416] For example, as shown in Figure 11 for example, one BWP includes 8 sub-bands, i.e., sub-band 1 to sub-band 8 based on frequency from large to small, and one time domain unit includes 6 slots; i.e., the network side device can indicate that sub-band 1 to sub-band 8 correspond to third index groups eSFI index1, eSFI index1, eSFI index2, eSFI index2, eSFI index3, eSFI index3, eSFI index1, eSFI index1 respectively, wherein eSFI index1 indicates “DDDDDD”, eSFI index2 indicates “DFUUUU”, and eSFI index3 indicates “DFFUUU”.
[0417] In the embodiments of the present application, the network side device can simultaneously indicate FFI and the time of action, i.e., enhanced slot format indication (eSFI).
[0418] For a carrier and / or BWP, the network side device can configure / indicate eSFI (enhanced slot format indication) for each sub-band. The eSFI can adopt a third frequency domain format table, and the third frequency domain format table can adopt an indication manner similar to Table 1.
[0419] For example, network-side devices can configure or indicate the number of subbands, and each subband can be configured or indicated with an eSFI index value (third index), thereby achieving the purpose of simultaneously indicating FFI and operating time through eSFI.
[0420] Optionally, the frequency domain format indication information includes a fourth index;
[0421] The fourth index is used to indicate the fourth target format group in the fourth frequency domain format table, wherein the fourth target format group includes at least one fifth target format group;
[0422] Each fifth target format group corresponds to a sub-band;
[0423] A fifth target format group is used to indicate the target transmission direction corresponding to at least one symbol, sub-slot, or slot in a time-domain resource unit;
[0424] The fifth frequency domain format table is pre-configured, protocol-predefined, or pre-instructed to the terminal by the network-side device.
[0425] Optionally, signaling indication for eSFI can be achieved by configuring a terminal in the DCI to monitor one or more eSFIs through a network-side device.
[0426] For example, such as Figure 12 As shown, the network-side device can configure the position of eSFI 5 in the DCI carrying eSFI for the backward UE1, and UE1 can determine the format of the slot based on the SFI-index of eSFI 5.
[0427] For example, the network-side device can configure the position of eSFI 6 in the DCI that carries eSFI for the backward UE2, and UE2 will determine the format of the slot based on the SFI-index of eSFI 6.
[0428] For example, the network-side device can configure UE3 with 4 subbands and configure it to monitor the position of eSFI 1-4 in the DCI carrying eSFI. UE3 will determine the format of the slot of each subband according to the SFI-index of eSFI 1-4.
[0429] Optionally, multiple eSFIs can be used to indicate the FFI and its duration of action for each FFI, thereby enabling a UE (group) to simultaneously indicate the FFI and its duration of action for each subband of each carrier or each BWP. This also ensures compatibility with backward UEs.
[0430] Optionally, the network-side equipment can configure the mapping relationship between subband numbers and eSFIs. For example, the network can configure the following mapping relationship for the UE:
[0431] {subband 1, eSFI 1};
[0432] {subband 2, eSFI 3};
[0433] {subband 3, eSFI 4};
[0434] {subband 4, eSFI 2}…
[0435] Further, the network side device can configure an index table of one subband and eSFI, i.e., a fifth frequency domain format table, as shown in Table 4 below, and then indicate by an index, i.e., a fourth index. Each eSFI can be indicated in a manner similar to Table 1.
[0436] Table 4: Fifth frequency domain format table
[0437]
[0438] It should be noted that Table 4 is only an example of the fifth frequency domain format table, and is not a limitation on the fifth frequency domain format table.
[0439] Optionally, the frequency domain format indication information is used to indicate a target time period in which the frequency domain format takes effect.
[0440] Optionally, for each subband, the frequency domain format indicated by the frequency domain format indication information takes effect in the target time period.
[0441] For example, the index can be indicated by an index.
[0442] For example, for each index of each eSFI, the eSFI taking effect time can be configured, for example, the time corresponding to each index can be configured by a higher layer, as shown in Table 5 (index taking effect time table a).
[0443] Table 5: Index taking effect time table a
[0444] eSFI-index Time of validity (slot format) 0 Single slot 1 Two-slot 2 Three-slot … …
[0445] It should be noted that Table 5 is only an example of the index taking effect time table, and is not a limitation on the index taking effect time table.
[0446] For example, the index can be indicated separately, as shown in Table 6 (index taking effect time table b).
[0447] Table 6: Index taking effect time table b
[0448]
[0449] It should be noted that Table 6 is only an example of the index taking effect time table, and is not a limitation on the index taking effect time table.
[0450] Optionally, the target time period includes:
[0451] The monitoring period for the terminal to receive the frequency domain format indication information is as follows:
