The resource determination method and apparatus provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.

In a communication system, a network configures BWP and/or a carrier for a terminal to perform data transmission. The bandwidth of the terminal may be dynamically changed.

Fig. 2 is a schematic view of BWP configuration provided in an embodiment of the present application, as shown in fig. 2, at a first time, a traffic of a terminal is large, and a system configures a large bandwidth (BWP 1) for the terminal; at the second moment, the traffic of the terminal is smaller, and the system configures a small bandwidth (BWP 2) for the terminal to meet the basic communication requirement; at the third moment, the system finds that there is wide frequency selective fading in the bandwidth of BWP1, or there is a shortage of resources in the frequency range of BWP1, and then allocates a new bandwidth (BWP 3) to the terminal.

Each BWP is not only frequency point and bandwidth diverse, but each BWP may correspond to a different configuration. For example, the subcarrier spacing, CP type, SSB (PSS/SSS PBCH Block) period, etc. of each BWP may be configured differently to accommodate different services.

The technical advantages of BWP are mainly four:

1. the terminal does not need to support all bandwidths, only needs to meet the requirement of the lowest bandwidth, and is beneficial to development of low-cost terminals;

2. when the terminal service volume is not large, the terminal can be switched to low bandwidth operation, and the power consumption can be obviously reduced;

3. the communication technology is forward compatible, when a new technology is added to the communication system, the new technology can be directly operated on a new BWP, and the forward compatibility of the system is ensured;

4. and the BWP is dynamically configured for the service according to the service requirement.

In addition, in the communication system, the uplink and downlink configuration can be based on the granularity of symbols, and the configuration is more flexible. The specific configuration process is as follows:

(1) Firstly, configuring semi-static uplink and downlink configuration of a cell;

the higher layer provides TDD-UL-DL-configuration common parameters, which include reference subcarrier spacing u (reference SCS configuration) and pattern1, and pattern1 includes:

a slot configuration period (slot configuration period) P ms;

the number of downlink slots Dslots (number of slots with only downlink symbols);

the number of downlink symbols Dsym (number of downlink symbols);

the number of uplink slots, ulocks (number of slots with only uplink symbols);

the number of uplink symbols Usym (number of uplink symbols);

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, and P =2.5ms is valid only for 30 and 120kHz subcarrier spacing. Then a configuration cycle can know how many slots the cycle contains by using the formula S = P × 2 u. Of these slots, the first dslotts slots are downlink slots, followed by Dsym downlink symbols, followed by Usym uplink symbols, and finally Uslots uplink slots. After configuring the uplink and the downlink in S time slots, the flexible symbol X is left.

If the parameters are given to both pattern1 and pattern2, two different slot formats can be configured consecutively, and the form of the parameters in pattern2 is similar to that of pattern 1.

(2) Then configuring special uplink and downlink configuration of the cell;

if a higher layer parameter TDD-UL-DL-configdivided is further provided on the basis of the configuration in (1), the parameter may configure a flexible symbol of the parameter TDD-UL-DL-configuration common configuration. That is, the uplink and downlink symbols configured in (1) may not be changed, but the flexible symbols may be overwritten by TDD-UL-DL-ConfigDedicated.

The parameter provides a series of slot configurations, for each slot configuration, a slot index and a symbol configuration, for a slot specified by the slot index, where:

if symbols = allDownlink, then all symbols in the slot are downlink;

if symbols = allUplink, all symbols in the slot are uplink;

if symbols = explicit, the parameter nrofDownlinkSymbols symbols first provides a number of downlink symbols;

that is, if it is explicit, the parameter nrofDownlinkSymbols provides the number of downlink symbols, nrofUplinkSymbols provides the number of uplink symbols, the downlink symbols being foremost and the uplink symbols being rearmost, if the parameter nrofDownlinkSymbols is not provided, there is no downlink symbol, and if nrofUplinkSymbols is not provided, there is no uplink symbol. If there is a remainder after configuration, the remaining symbols are still flexible symbols X. (2) The reference subcarrier spacing reference SCS configuration in (1) is the same as in (1).

The uplink and downlink configuration realized by the dynamic DCI is realized through DCI format 2-0, or directly realized through the uplink and downlink data scheduling of DCI format 0-1-0-1. DCI format 2-0 is used exclusively for SFI indication. The SFI implements a periodic frame structure configuration mainly according to a slot format supportable by a single slot, that is, starting from receiving DCI format 2-0, a Physical Downlink Control Channel (PDCCH) monitoring period (slot) is continued, and the slots are configured according to an indication of slot format indication Information (SFI) in the Downlink Control Information (DCI). The maximum number of formats supported by a single slot is 256, and the standardized format is 56. The slot format table of the normal cp is shown in table 1 below (slot format table of normal cyclic prefix);

Optionally, the network side device may indicate a target transmission direction of each subband, where the target transmission direction may be an uplink direction, a downlink direction, or a flexible direction;

alternatively, the network side device may send Frequency-domain Format Indication (FFI) information to the terminal. The frequency domain format indication information indicates the terminal to indicate the transmission direction of uplink and downlink in the frequency domain with subband granularity on one or more BWPs or one or more carriers.

Optionally, the frequency domain format indication information may indicate which frequency domain resources are used as resources for uplink transmission, which are used as resources for downlink transmission, and which can be used as resources for flexible transmission, and the resources indicated as flexible transmission may be continuously indicated by a subsequent network side device or determined by the terminal based on a current transmission task or a predefined rule, for example, indicated as resources for UL or DL transmission through DCI or higher layer signaling.

Optionally, the terminal may receive frequency domain format indication information sent by the network side device; then, the terminal may determine a target transmission direction, such as an uplink direction, or a downlink direction, or a flexible direction, corresponding to at least one subband in one frequency domain resource unit based on the frequency domain format indication information.

Alternatively, the sub-band for which the target transmission direction is indicated to be the flexible direction may be referred to as a flexible sub-band;

alternatively, the subbands for which the target transmission direction is indicated to be other than a flexible direction may be referred to as non-flexible subbands.

Optionally, an embodiment of the present application provides a method for indicating a frequency domain format of a frame/timeslot, which can implement flexible uplink and downlink transmission in a frequency domain within a certain time.

Optionally, the determining, by the terminal, target transmission directions respectively corresponding to at least one sub-band in one frequency domain resource unit based on the frequency domain format indication information includes:

and the terminal determines the size of each sub-band in the at least one sub-band and the number of the at least one sub-band based on the first indication information sent by the network side equipment.

Alternatively, the network side device may configure the terminal with subband information, that is, the first indication information, where the subband information may divide one carrier or BWP into multiple subbands.

Alternatively, the terminal may receive the first indication information and then divide one carrier or BWP into a plurality of subbands based on the subband information, i.e., the first indication information.

Optionally, the network side device may send the first indication information to the terminal, and may indicate, by the first indication information, a size of each sub-band and a number of the at least one sub-band when the terminal divides one frequency domain unit into multiple sub-bands.

Alternatively, the terminal may receive the first indication information, determine the size of each sub-band and the number of the at least one sub-band based on the first indication information, and then divide one frequency domain unit into a plurality of sub-bands.

Alternatively, the network side device may first configure the subband size.

Optionally, the network side device may configure the size of a reference sub-band of a reference sub-carrier interval according to different SCS, and the size of other sub-bands is calculated according to the corresponding BWP or sub-carrier interval of the carrier, the reference sub-carrier interval, and the reference sub-band size.

For a BWP, the subband size may be configured by the network side device, e.g., may be equal to the size of the RBG, and determined by the bandwidth of the BWP.

Optionally, the terminal may determine, based on the first indication information sent by the network side device, a size of each sub-band and a number of the at least one sub-band when one frequency domain unit is divided into multiple sub-bands.

For example, table 2 is a sub-band size configuration table, which may indicate that the sub-band size is the same as the RBG size, determined by the BWP bandwidth; if a BWP is 128 RBs, a subband is 16 RBs if Configuration2 is used.

TABLE 2 subband size configuration table

Optionally, the frequency domain format indication information includes: at least one second indication information corresponding to the at least one sub-band;

wherein the target transmission direction of the at least one subband is indicated by the second indication information based on whether the subband frequency of the at least one subband is from low to high or from high to low.

Fig. 4 is a schematic diagram of a resource determination method according to an embodiment of the present application, and as shown in fig. 4, a target transmission direction of at least one subband is indicated by the second indication information based on a subband frequency of the at least one subband from low to high or from high to low; i.e., the FFI may be indicated from the subband low frequency to high frequency direction, or vice versa, may be configured by the network side device.

For example, if the FFI is "DDFFFUUD", the subband is from low frequency to high frequency, the first subband is DL downlink, the second subband is DL downlink, the third subband is flexible direction, the fourth subband is flexible direction, the fifth subband is flexible direction, the sixth subband is UL uplink, the seventh subband is UL uplink, and the eighth subband is DL downlink transmission.

Optionally, fig. 5 is a second schematic diagram of the resource determining method provided in the embodiment of the present application, as shown in fig. 5, the network side device may configure at least one flexible subband for each carrier or for each bwp through the frequency domain format indication information, and may only allow to change the flexible subband when indicated again through the frequency domain format indication information FFI. The other sub-bands are not allowed to be modified. The complexity and signaling overhead of the indication can be reduced.

Optionally, the size of the frequency domain format indication information is determined based on the number of the at least one sub-band.

Optionally, in a case that a target transmission direction of at least one sub-band is indicated by the second indication information based on a sub-band frequency of the at least one sub-band from low to high or from high to low, a size of the frequency domain format indication information is determined based on a number of the at least one sub-band.

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

Alternatively, the network may semi-statically indicate that the transmission direction of some sub-bands is UL or DL. Indicated by FFI for the remaining flexible subbands. The frequency domain format indication information comprises: a reference transmission direction indication information, and a number and a location of the flexible subbands.

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

Alternatively, to reduce signaling overhead, for one BWP, the network side device may semi-statically configure or indicate the transmission direction of the frequency domain reference at one time or some times through the SFI, and the number M of flexible subbands and the location of the flexible subbands.

Optionally, the network side device may indicate that the reference direction is a downlink direction DL or an uplink direction UL;

optionally, for a BWP reference with a DL or UL transmission direction, the network side device may configure K subbands as flexible subbands; the transmission directions of the subbands other than the K flexible subbands are both downlink direction DL or uplink direction UL.

and the terminal determines a flexible sub-band in the at least one sub-band and a target transmission direction of a non-flexible sub-band in the at least one sub-band based on the reference direction indication information, wherein the non-flexible sub-band is a sub-band which is not a flexible sub-band in the at least one sub-band.

Optionally, the network side device may indicate that the reference direction is a downlink direction DL or an uplink direction UL, and may determine that the transmission directions of the subbands other than the flexible subband are both the downlink direction DL or the uplink direction UL;

optionally, the network side device may subsequently change only the direction of the flexible subband, for example, one FFI indicates that the flexible subband N is changed to the uplink or downlink direction, and the non-indicated subband (M-N) is determined according to the reference transmission direction.

Optionally, the network side device may subsequently change only the direction of the flexible subband, for example, one FFI indicates that the flexible subband N is changed to the uplink or downlink direction, and the non-indicated flexible subband (O-N) is determined according to the reference transmission direction.

For example, if the terminal receives the frequency domain format indication information again, and the transmission direction referred by the BWP is DL at this time, the network side device is configured with L subbands as flexible subbands, the frequency domain format indication information FFI may indicate the number and positions of the L flexible subbands used as UL subbands, and for the remaining flexible subbands that are not indicated, the reference transmission direction may be DL;

optionally, the network side may also be configured, and in addition to the L subbands, other subbands in the flexible subbands still remain the same in the flexible direction.

Alternatively, the network side device may indicate that the FFI may be indicated by a high-layer signaling semi-static indication or Media Access Control information (MAC CE) indication or dynamically indicated by DCI.

Alternatively, the network side device may configure the subband size first.

Optionally, the size of the frequency domain format indication information is determined based on the number of the flexible subbands, and the transmission directions of other subbands are indicated by the network side semi-statically.

For example, the network side device indicates the frequency domain formats of D, U, and F using the continuous resource indication method in units of subbands. The frequency domain format indication information comprises: with reference to the direction indication information,the number and position of the flexible sub-bands are required separately

bit indicates the frequency domain resources of D, U and F.

Alternatively, if the high-layer configuration FFI can only indicate that the flexbile resource changes the transmission direction, the signaling overhead can be saved.

Fig. 6 is a third schematic diagram of a resource determination method according to the embodiment of the present application, and as shown in fig. 6, the reference direction is DL, and the FFI indicates that a flexible resource is changed to an UL transmission direction and indicates that the flexible resource is an UL subband

The remaining F subbands are the DL direction. If the transmission direction of 5 flexible subbands is indicated in the form of bitmap, 5 bits are needed.

Alternatively, the transmission direction of the reference, i.e., the reference direction indication information, may also be indicated by the SFI.

Optionally, the reference transmission direction, i.e. the reference direction indication information, may also be configured by the network.

Optionally, the frequency domain format indication information includes: a first index; the first index is used for indicating a first target format group in a first frequency domain format table; each first target format group in the first frequency domain format table comprises each sub-band and a target transmission direction corresponding to each sub-band;

the first frequency domain format table is pre-configured or protocol predefined or pre-indicated by a network side device.

Alternatively, the system may be preconfigured or the protocol may be predefined or the network side device may indicate an index table for FFI indication in advance, that is, a first frequency domain format table, including at least one first index and a first target format group corresponding to each first index, where each first target format group may indicate target transmission directions corresponding to all subbands in one carrier or one BWP.

Alternatively, in a case where the terminal knows the first frequency domain format table, the network side device may send the first index to the terminal, and the network side device may indicate the transmission direction of all subbands of the target carrier or BWP by indicating the first index.

Optionally, in a case that the terminal knows the first frequency domain format table, the terminal may receive the first index sent by the network side device, and determine, through the first index, the first target format group corresponding to the first index in the first frequency domain format table, and further determine the indication content corresponding to the first target format group, that is, the transmission directions of all subbands of the target carrier or the BWP.

Alternatively, the network may configure an n-column table for all subbands n of a carrier or BWP. Taking 8 subbands as an example, table 3 may be a first frequency domain format table, and the transmission directions of all subbands may be indicated by indicating one index.

Table 3 first frequency domain format table

It should be noted that table 3 is only an example of the first frequency domain format table, and is not a limitation on the first frequency domain format table.

Alternatively, the first to seventh sub-bands may be one BWP or one directional ordering determination of all sub-bands from sub-band low frequency to high frequency or from sub-band high frequency to low frequency in one carrier.

For example, the first index included in the frequency domain format indication information is 3, that is, the first sub-band to the seventh sub-band are indicated as "dffuuuu", the terminal may determine that the first sub-band is in a DL downlink direction, the second sub-band is in a flexible direction, the third sub-band is in a flexible direction, the fourth sub-band is in an UL uplink direction, the fifth sub-band is in an UL uplink direction, the sixth sub-band is in an UL uplink direction, and the seventh sub-band is in an UL uplink direction.

Optionally, the receiving, by the terminal, the frequency domain format indication information sent by the network side device includes:

If no DCI is monitored, the transmission may be performed according to tdd-UL-DL-configuration common, or tdd-UL-DL-configuration dedicatered or SFI, or uplink and downlink of dynamic scheduling or higher layer configuration. For example, the UE is configured with 1 slot as a periodic CG or SPS, and the CG and SPS transmit and receive only in the active transmission direction.

the terminal does not monitor the time domain format indication information SFI.

Optionally, for the UE configured with the FFI, the network side device may configure the UE to detect only the DCI carrying the FFI, and not monitor the DCI carrying the SFI.

the terminal determines the target transmission direction of the flexible sub-band based on the frequency domain format indication information;

and the terminal determines the target transmission direction of the non-flexible sub-band based on the time domain format indication information SFI.

and the terminal determines the target transmission direction of the flexible sub-band based on the new frequency domain format indication information.

Alternatively, corresponding to resources in different uplink and downlink directions, a guard band may be configured for the purpose of uplink and downlink conversion, etc.

Alternatively, for consecutive subbands, no guard band may be left if the transmission directions are the same, i.e., no guard band may be configured between adjacent subbands with the same target transmission direction. Alternatively, the guard band may be indicated by:

configuration by the network semi-statically;

defined by a predefined rule, i.e. guard band is contained in the previous frequency domain resource and/or the next frequency domain resource;

and the F resource is contained by the dynamic indication.

Optionally, for the signaling carrying the FFI is dynamic signaling, the DCI carrying the FFI may be UE-specific or group common DCI. The DCI size may be the same as one other DCI payload size, e.g., aligned with the SFI payload size, e.g., a maximum of n bits, n may be 128bits.

Alternatively, padding bits may be padded to bit alignment if the DCI for one FFI does not match the aligned DCI payload size.

Alternatively, if the size of the DCI carrying the FFI is the same as the other DCI sizes, the network may configure one RNTI for scrambling the DCI, e.g., using FFI-RNTI scrambling. The RNTI is used to distinguish DCI carrying FFI from DCI of the same payload size.

Fig. 17 is a fourteenth exemplary diagram illustrating a resource determination method implemented by the present application, and as shown in fig. 17, for indicating FFI of one or more carriers of one or more BWPs, a network may indicate a reference subcarrier spacing since there may be different subcarrier spacings. And the FFI (or eSFI) is indicated according to the reference subcarrier interval, and the UE converts the FFI (or eSFI) according to the configured subcarrier interval and/or the subcarrier interval of the BWP according to the reference subcarrier interval.

For example BWP1 is 15kHz SCS. BWP2 is 30kHz SCS. With reference to 15kHZ for SCS and 8RB for subband size, the frequency domain granularity indicated by FFI is 8RB at BWP1 and 16RB at BWP 2.

Alternatively, the time domain unit may be different according to the difference of the reference subcarrier spacing. I.e. the reference subcarriers need to take time-frequency resources into account.

Fig. 18 is a second schematic flowchart of a resource determining method according to an embodiment of the present application, and as shown in fig. 18, the method includes the following steps:

step 1800, a network side device sends frequency domain format indication information, wherein the frequency domain format indication information is used for indicating a target transmission direction corresponding to at least one sub-band in a frequency domain resource unit;

Optionally, the network side device may instruct the terminal to divide the entire frequency band into multiple sub-bands.

Alternatively, the first time unit may be X symbols/slot, X > =1.

Optionally, the method further comprises:

and the network side equipment sends first indication information, wherein the first indication information is used for indicating the size of each sub-band in the at least one sub-band and the number of the at least one sub-band.

Alternatively, the terminal may receive the first indication information and then divide one carrier or BWP into a plurality of subbands based on subband information, i.e., the first indication information.

Alternatively, the network side device may configure the subband size first.

For example, table 2 is a sub-band size configuration table, which may indicate that the sub-band size is the same as the RBG size, determined by the BWP bandwidth; if one BWP size is 128 RBs, if the configuration uses configuration2, one subband size is 16 RBs.

TABLE 2 subband size configuration table

Optionally, as shown in fig. 4, the target transmission direction of at least one subband is indicated by the second indication information based on whether the subband frequency of the at least one subband is from low to high or from high to low; i.e., the FFI may be indicated in the direction from subband low frequency to high frequency, or vice versa, configurable by the network side device.

For example, if the FFI is "DDFFFUUD", the subband is from low frequency to high frequency, the first subband is DL downlink, the second subband is DL downlink, the third subband is flexible direction, the fourth subband is flexible direction, the fifth subband is flexible direction, the sixth subband is UL uplink, the seventh subband is UL uplink, and the eighth subband is DL downlink.

Optionally, as shown in fig. 5, the network side device may configure at least one flexible sub-band for each carrier or for each bwp through the frequency domain format indication information, and may only allow to change the flexible sub-band when indicated again by the frequency domain format indication information FFI. The other sub-bands are not allowed to be modified. The complexity and signaling overhead of the indication can be reduced.

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

Alternatively, the network may semi-statically indicate that the transmission direction of some sub-bands is UL or DL. Indicated by FFI for the remaining flexible subbands. The frequency domain format indication information comprises: the number and location of the flexible subbands are referenced to direction indication information.

For example, if the terminal receives the frequency domain format indication information again, at this time, the transmission direction referenced by the BWP is DL, the network side device is configured with L subbands as flexible subbands, the frequency domain format indication information FFI may indicate the number and positions of the L flexible subbands used as UL subbands, and the remaining flexible subbands not indicated may be the reference transmission direction, that is, DL;

Optionally, the network side device may indicate that the FFI may be indicated by a higher layer signaling semi-static indication or a MAC CE indication or dynamically indicated by DCI.

Alternatively, the network side device may configure the subband size first.

Optionally, the network device may configure a reference subband size of a reference subcarrier interval according to different SCS, and the other subbands are calculated according to a corresponding BWP or subcarrier interval of the carrier, the reference subcarrier interval, and the reference subband size.

For example, the network side device indicates the frequency domain format of D, U, and F using the consecutive resource indication method in units of subbands. The frequency domain format indication information comprises: with reference to the direction indication information, the number and position of the flexible subbands are required

bit indicates the frequency domain resources of D, U and F.

Alternatively, as shown in fig. 6, the reference direction is DL, the FFI indicates that the flexbile resource is changed to the UL transmission direction,

the remaining F subbands are the DL direction. If the transmission direction of 5 flexible subbands is indicated in the form of a bitmap, then 5 bits are needed.

Optionally, in a case that the terminal knows the first frequency domain format table, the network side device may send the first index to the terminal, and the network side device may indicate the transmission directions of all subbands of the target carrier or BWP by indicating the first index.

Alternatively, the network may configure an n-column table for all subbands n of a carrier or BWP.

Taking 8 subbands as an example, table 3 may be a first frequency domain format table, and the transmission directions of all subbands may be indicated by indicating one index.

Table 3 first frequency domain format table

Optionally, the sending, by the network side device, the frequency domain format indication information includes:

the network side equipment sends at least one piece of frequency domain format indication information;

Alternatively, a location of an FFI may be configured for each carrier or each BWP in the DCI, that is, a target transmission direction of all sub-bands in each carrier or each BWP is indicated.

Alternatively, as shown in fig. 7, DCI carrying the FFI may contain FFIs of multiple carriers.

Optionally, as shown in fig. 8, DCI carrying FFI may contain FFIs of multiple BWPs; for example, BWP1 has 8 sub-bands, BWP2 has 8 sub-bands, BWP3 has 8 sub-bands, …, and BWP n has 8 sub-bands; FFI1 indicates "UUFFUDDU", FFI2 indicates "UDFFUDUU", FFI3 indicates "UFFFFDUU", …, and FFI n indicates "UFDFFDUU"; the terminal may determine that the target transmission directions of the 8 subbands are "UUFFUDDU", respectively, based on FFI1 indicating BWP 1; the terminal may determine that the target transmission directions of the 8 sub-bands are "UFFFFDUU", respectively, based on the FFI2 indicating BWP 2; the terminal may determine that the target transmission directions of the 8 subbands are "UFFFFDUU", respectively, based on the FFI3 indicating BWP 3; …; the terminal may determine that the target transmission directions of the 8 subbands are "UFDFFDUU", respectively, based on the FFI n indicating BWP n.

For example, referring also to fig. 8, when the UE is configured to use BWP1, the UE uses FFI1, i.e. it may be determined that the target transmission directions of the 8 sub-bands are "UUFFUDDU", respectively, and when the UE uses BWP2, the UE uses FFI2.

Optionally, as shown in fig. 9, the network side device may also jointly indicate, to one terminal group, each bwp and the FFI of each carrier.

For example, the UE is configured for carrier aggregation of 2 carriers, and for carrier 1, the UE is configured with 3 BWPs, BWP1, BWP2, BWP3. For carrier 2, the ue is configured with 3 BWPs, BWP1, BWP2, BWP3 respectively. When the UE is configured for BWP1 for carrier 1 and BWP3 for carrier 2, the UE will determine the frequency domain format from FFI1 and FFI 6.
