[0284] The method and the device are based on the same application concept. Since the principles of the method and the device for solving problems are similar, the implementation of the device and the method can be referred to each other, and the repeated parts will not be described again.

For example, the applicable systems can be global system of mobile communication (GSM) systems, code division multiple access (CDMA) systems, wideband code division multiple access (WCDMA) general packet radio service (GPRS) systems, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, LTE time division duplex (TDD) systems, long term evolution advanced (LTE-A) systems, universal mobile telecommunication system (UMTS), worldwide interoperability for microwave access (WiMAX) systems, 5G new radio (NR) systems, and the like. The various systems all include terminal devices and network devices. The system can also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), and the like. These systems can provide cellular coverage using NTN technology, which is not limited by the present application.

[0286] The terminal device to which the embodiments of the present application relate can refer to a device that provides voice and / or data connectivity to a user, a handheld device having a wireless connection function, or other processing devices connected to a wireless modem, etc. In different systems, the name of the terminal device can also be different, for example, in the 5G system, the terminal device can be called user equipment (UE). The wireless terminal device can communicate with one or more core networks (CN) through a radio access network (RAN). The wireless terminal device can be a mobile terminal device, such as a mobile phone (or called "cellular" phone) and a computer with a mobile terminal device, for example, it can be a portable, pocket, handheld, computer built-in or vehicle-mounted mobile device, which exchanges language and / or data with the radio access network.

[0287] The network device related to the embodiments of the present application can be a base station, which can include multiple cells serving terminals. According to different application scenarios, the base station can also be referred to as an access point, or can be a device in an access network that communicates with wireless terminal devices through one or more sectors over an air interface, or other names. The network device can be used to exchange received air frames and Internet Protocol (IP) packets as a router between wireless terminal devices and the rest of the access network, which can include an Internet Protocol (IP) communication network. The network device can also coordinate the management of the properties of the air interface. For example, the network device related to the embodiments of the present application can be a network device (Base Transceiver Station, BTS) in the Global System for Mobile Communications (GSM) or Code Division Multiple Access (CDMA), or a network device (NodeB) in Wide-band Code Division Multiple Access (WCDMA), or an evolved network device (evolutional Node B, eNB or e-NodeB) in a long term evolution (LTE) system, or a 5G base station (gNB) in a next generation system, or a Home evolved Node B (HeNB), a relay node, a femto, a pico, etc., which are not limited in the embodiments of the present application. In some network structures, the network device can include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit can also be geographically separated.

[0288] The network device and the terminal device can each use one or more antennas for multi-input multi-output (MIMO) transmission, which can be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). According to the shape and number of root antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO or massive-MIMO, or can be diversity transmission or precoding transmission or beamforming transmission, etc.

[0289] Both TDD and frequency division duplex (FDD) duplex communication modes are supported in 5G NR. Among them, the TDD mode can support sending and receiving at different times in the same frequency channel, i.e., carrier, and the resources of uplink and downlink transmission are distinguished by time; the FDD mode can support sending and receiving at the same time in different frequency channels, and the resources of uplink and downlink transmission are distinguished by frequency.

[0290] 5G NR will support SBFD mode in Rel-19, i.e., the network device and the terminal can simultaneously send and receive in different subbands within a TDD carrier, and the subbands used for sending and receiving do not overlap.

[0291] The SBFD mode is implemented based on SBFD symbols, which are symbols containing both uplink subbands for uplink transmission and downlink subbands for downlink transmission, i.e., symbols containing both uplink frequency domain resources and downlink frequency domain resources in the frequency domain. Currently, SBFD symbols can be configured in downlink symbols or flexible symbols of TDD-UL-DL-ConfigCommon configuration. For a subband full duplex system, the currently supported subband configurations mainly include two types, which are SBFD subband configuration 1 and SBFD subband configuration 2. The following will introduce these two subband configurations. Figure 1

[0292] Figure 1 For the subband full duplex system, the supported subband configurations are shown in the schematic diagram as Figure 1 For SBFD symbols, it includes an SBFD slot in the time domain and uplink subbands and downlink subbands in the frequency domain.

[0293] Please refer to Figure 1 ​For SBFD sub-band configuration 1, a {DUD} mode (D represents downlink, and U represents uplink) is used, that is, one SBFD symbol contains one uplink sub-band and two downlink sub-bands, the uplink sub-band is located at the center of the carrier bandwidth, and the two downlink sub-bands are respectively located at two sides of the carrier bandwidth; for SBFD sub-band configuration 2, a {DU} mode is used, that is, one SBFD symbol contains one uplink sub-band and one downlink sub-band, the uplink sub-band is located at one side of the carrier bandwidth, and the downlink sub-band is located at the other side of the carrier bandwidth.

[0294] In the above embodiments, the SBFD symbol sub-band configuration is combined with Figure 1 The SBFD symbol sub-band configuration is introduced, and the determination manner of frequency domain resource allocation (FDRA) in downlink control information (DCI) is introduced.

[0295] The transmission scheduled by DCI can include a physical uplink shared channel (PUSCH) and a physical downlink shared channel (PDSCH). DCI can have multiple formats, such as DCI format 0_0, DCI format 1_0, and the like. Among them, DCI format 0_0 is mainly used to schedule the transmission of PUSCH, and DCI format 1_0 is mainly used to schedule the transmission of PDSCH.

[0296] The FDRA size of DCI format 0_0 in the common search space (CSS) depends on the initial uplink (initial UL) BWP. For the PUSCH scheduled by DCI format 0_0 in the CSS, the bandwidth that can be scheduled is equal to the bandwidth of the initial uplink BWP, and the RB numbering is started based on the lowest RB corresponding to the activated uplink BWP.

[0297] The FDRA size of DCI format 1_0 in CSS depends on the bandwidth of CORESET 0 when the carrier is configured with CORESET 0, otherwise depends on the bandwidth of initial DL BWP. CORESET is a set of resources used for transmission of Physical Downlink Control Channel (PDCCH), and DCI is transmitted through PDCCH, DCI needs to indicate all possible PDSCH resource locations within the bandwidth of CORESET 0, so the bandwidth of CORESET 0 directly affects the size of FDRA in DCI format 1_0.

[0298] For PDSCH scheduled by DCI format 1_0 in CSS, RB numbering starts from the lowest RB corresponding to the CORESET where the DCI is located. When the carrier is configured with CORESET 0, the schedulable bandwidth is equal to the bandwidth of CORESET 0, otherwise it is equal to the bandwidth of initial DL BWP.

[0299] In some cases (when the size of DCI exceeds the limit of 3+1, that is, the number of DCI sizes that the terminal needs to blindly detect exceeds 3 special DCI sizes and 1 common DCI size), the size of FDRA of DCI format 0_0 and DCI format 0_1 in user-specific search space (UE-specific Search Space, USS) is also determined in the same way as in CSS.

[0300] For PUSCH scheduled by DCI format 0_0 and PDSCH scheduled by DCI format 1_0 in USS, if the FDRA size of DCI in USS and the FDRA size of DCI in CSS are the same, but the scheduled PUSCH / PDSCH transmission is in an active uplink BWP / active downlink BWP, then the frequency domain resource allocation is performed with K as the granularity. The indicated frequency domain resource starting position The length of consecutive virtual resource blocks (VRB) is represents the number of RBs of the initial BWP, represents the number of RBs of the active BWP. When K satisfies The maximum value in the set {1, 2, 4, 8}, otherwise K = 1.

[0301] In the above embodiments, how to determine the frequency domain resource of the PUSCH / PDSCH scheduled by the DCI is introduced. For the SBFD symbol in the Rel-19 SBFD system, only uplink transmission is supported in the uplink subband, only downlink reception is supported in the downlink subband, and in some cases, the DCI format 0_0 or DCI format 1_0 scheduled transmission can not be able to indicate the resource within the subband for transmission.

[0302] A specific example is introduced as an example. Figure 2 For a schematic diagram for determining the frequency domain resource of the PUSCH, as shown in Figure 2 , an example of the DCI format 0_0 scheduled PUSCH transmission is shown.

[0303] Based on the above embodiments, for the DCI format 0_0 scheduled PUSCH in the CSS, the bandwidth that can be scheduled is equal to the bandwidth of the initial uplink BWP, and the RB numbering is started based on the lowest RB corresponding to the activated uplink BWP. In this way, the frequency domain range indicated by the FDRA can be determined. As shown in Figure 2 , the frequency domain range indicated by the FDRA, the frequency domain range of the activated uplink BWP, and the frequency domain range of the uplink subband in the SBFD symbol are respectively shown. When the uplink subband in the SBFD symbol is outside the frequency domain range indicated by the FDRA, the PUSCH transmission cannot be scheduled.

[0304] In Figure 2 , the case that when the uplink subband in the SBFD symbol is outside the frequency domain range indicated by the FDRA, the PUSCH transmission cannot be scheduled is introduced by taking the DCI format 0_0 scheduled PUSCH transmission in the CSS as an example. In some embodiments, if the FDRA size of the DCI in the USS and the FDRA size of the DCI in the CSS are the same, for the frequency domain range indicated by the FDRA contained in the DCI format 0_0 in the USS, the bandwidth of the initial uplink BWP is equal to the bandwidth that can be scheduled, and when the uplink subband in the SBFD symbol is outside the frequency domain range indicated by the FDRA, the PUSCH transmission cannot be scheduled. The process for PDSCH transmission is similar and will not be described here.

[0305] In summary, since the uplink subband in the SBFD symbol can only support uplink transmission and the downlink subband in the SBFD symbol can only support downlink transmission, the above frequency domain resource determination method can cause the corresponding uplink subband / downlink subband to be outside the frequency domain range indicated by the FDRA, and the transmission of the corresponding physical channel cannot be scheduled.

[0306] Based on the above technical problems, the embodiments of the present application provide a frequency domain resource determination method and device and a storage medium. The scheme of the embodiments of the present application will be introduced below in conjunction with the drawings.

[0307] Figure 3 A flowchart of the frequency domain resource determination method provided by the embodiments of the present application is shown in FIG. 1, which includes the following steps. Figure 3

[0308] S31, for a physical channel transmitted in an SBFD symbol, determining a frequency domain resource for transmitting the physical channel in the activated BWP based on the frequency domain position of the target subband; wherein the target subband is a subband in the SBFD symbol that matches the transmission direction of the physical channel.

[0309] The scheme of the embodiments of the present application can be applied to a wireless communication system, involving the interaction between a terminal and a network device, and the transmission of a physical channel between the terminal and the network device.

[0310] The execution subject of the embodiments of the present application can be a terminal or a network device. If the execution subject is a terminal, the terminal transmits a physical channel by determining a frequency domain resource for transmitting the physical channel; if the execution subject is a network device, the network device transmits a physical channel by determining a frequency domain resource for transmitting the physical channel.

[0311] For example, if the physical channel is a PUSCH, the terminal transmits the PUSCH by determining a frequency domain resource for transmitting the PUSCH, and the network device receives the PUSCH transmitted by the terminal by determining a frequency domain resource for transmitting the PUSCH. For example, if the physical channel is a PDSCH, the network device transmits the PDSCH by determining a frequency domain resource for transmitting the PDSCH, and the terminal receives the PDSCH transmitted by the network device by determining a frequency domain resource for transmitting the PDSCH.

[0312] Optionally, the terminal in the embodiments of the present application can be an SBFD terminal. The SBFD terminal is a terminal that supports SBFD. The terminal that supports SBFD is a terminal that knows the SBFD subband configuration, or a terminal that knows the network device performs the SBFD operation, or a terminal of a later version; the terminal that does not support SBFD is a terminal that does not know the SBFD subband configuration, or a terminal that does not know the network device performs the SBFD operation, or a terminal of an early version.

[0313] The SBFD symbol includes an uplink subband and a downlink subband, wherein the uplink subband supports uplink transmission, and the downlink subband supports downlink transmission. The target subband is a subband in the SBFD symbol that matches the transmission direction of the physical channel. If the transmission direction of the physical channel is uplink, the target subband is the uplink subband; if the transmission direction of the physical channel is downlink, the target subband is the downlink subband.

[0314] ​The activated BWP belongs to a BWP, in a wireless network, a carrier bandwidth can be divided into a set of contiguous common RBs, which constitute a BWP, and the BWP belongs to a subset of a cell bandwidth. The activated BWP is a working bandwidth adopted by the terminal, and the terminal can only transmit physical channels within the activated BWP.

[0315] In the embodiments of the present application, for the physical channel transmitted in the SBFD symbol, the terminal determines the frequency domain resource for transmitting the physical channel in the activated BWP based on the frequency domain position of the target subband. Since the frequency domain resource for transmitting the physical channel is determined based on the frequency domain position of the target subband, the target subband can be within the frequency domain range indicated by the FDRA, so that the transmission of the corresponding physical channel can be normally scheduled.

[0316] The frequency domain resource determination method provided by the embodiments of the present application determines the frequency domain resource for transmitting the physical channel in the SBFD symbol in the activated BWP based on the frequency domain position of the target subband. The target subband is a subband in the SBFD symbol that matches the transmission direction of the physical channel. Since the frequency domain resource for transmitting the physical channel is determined based on the frequency domain position of the target subband, the effective frequency domain resource can be determined in the activated BWP, so that the target subband matches the frequency domain resource, and the transmission of the physical channel is scheduled.

[0317] On the basis of any of the above embodiments, the scheme of the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0318] It should be noted that the execution subject in each embodiment of the present application can be a terminal or a network device. In the following embodiments, the execution subject is taken as a terminal for ease of description, and this does not limit the actual execution subject.

[0319] Optionally, the frequency domain resource allocation type of the physical channel can be any resource allocation type, for example, it can include resource allocation type 0 (Type 0), resource allocation type 1 (Type 1), etc. Among them, in the Type 0 resource allocation type, the frequency domain resource is discontinuously allocated in the entire bandwidth. This resource allocation method helps to improve the reliability of data transmission in the presence of frequency domain selective fading or interference. In the Type 1 resource allocation type, the frequency domain resource is continuously allocated in the entire bandwidth. This resource allocation method helps to simplify signal processing and improve spectral efficiency.

[0320] Optionally, the frequency domain resource allocation type of the physical channel is Type 1, that is, the frequency domain resource of the physical channel is continuous in the bandwidth.

[0321] Optionally, the physical channel transmitted in the SBFD symbol can include a PUSCH and / or a PDSCH. In the case where the physical channel is a PUSCH, the target sub-band is an uplink sub-band in the SBFD symbol; in the case where the physical channel is a PDSCH, the target sub-band is a downlink sub-band in the SBFD symbol.

[0322] For the physical channel transmitted in the SBFD symbol, the frequency domain resource used for transmitting the physical channel can be determined in the activated BWP based on the frequency domain location of the target sub-band. Optionally, the physical channel transmitted in the SBFD symbol is a physical channel satisfying a preset condition, wherein the preset condition includes at least one of the following conditions 1.1 to 1.5:

[0323] Condition 1.1, the M transmission symbols of the physical channel all belong to the SBFD symbol, and M is the number of transmission symbols of the physical channel.

[0324] The terminal can determine the transmission symbols of the physical channel, and M represents the number of transmission symbols of the physical channel, and M is a positive integer. Condition 1.1 indicates that the terminal can determine the symbol type of the M transmission symbols of the physical channel, and if the symbol type of the M transmission symbols all belong to the SBFD symbol, it can be determined that the physical channel is a physical channel transmitted in the SBFD symbol. If there is at least one transmission symbol in the M transmission symbols whose symbol type does not belong to the SBFD symbol, it can be determined that the physical channel is not a physical channel transmitted in the SBFD symbol.

[0325] For any transmission symbol in the M transmission symbols, it can be determined whether the transmission symbol belongs to the SBFD symbol by judging whether the transmission symbol simultaneously includes an uplink sub-band and a downlink sub-band in the frequency domain. If the transmission symbol simultaneously includes an uplink sub-band and a downlink sub-band in the frequency domain, the transmission symbol belongs to the SBFD symbol; if the transmission symbol does not simultaneously include an uplink sub-band and a downlink sub-band in the frequency domain, the transmission symbol does not belong to the SBFD symbol.

[0326] Condition 1.2, the first transmission symbol in the M transmission symbols belongs to the SBFD symbol.

[0327] The terminal can only determine whether the first transmission symbol of the physical channel belongs to the SBFD symbol. If yes, it can be determined that the physical channel is a physical channel transmitted in the SBFD symbol; if no, it can be determined that the physical channel is not a physical channel transmitted in the SBFD symbol.

[0328] Condition 1.3, the last transmission symbol in the M transmission symbols belongs to the SBFD symbol.

[0329] The terminal can only determine whether the last transmission symbol of the physical channel belongs to the SBFD symbol. If yes, it can be determined that the physical channel is a physical channel transmitted in the SBFD symbol; if no, it can be determined that the physical channel is not a physical channel transmitted in the SBFD symbol.

[0330] Condition 1.4, the number of transmission symbols belonging to the SBFD symbol in the M transmission symbols is greater than or equal to a preset number.

[0331] The terminal can determine the symbol type of the M transmission symbols of the physical channel, which is belonging to the SBFD symbol or not. If the number of transmission symbols belonging to the SBFD symbol in the M transmission symbols is greater than or equal to a preset number, it can be determined that the physical channel is a physical channel transmitted in the SBFD symbol; if the number of transmission symbols belonging to the SBFD symbol in the M transmission symbols is less than the preset number, it can be determined that the physical channel is not a physical channel transmitted in the SBFD symbol. Wherein, the preset number is less than or equal to M.

[0332] Condition 1.5, the ratio of the number of transmission symbols belonging to the SBFD symbol in the M transmission symbols to M is greater than or equal to a preset ratio.

[0333] The terminal can determine the symbol type of the M transmission symbols of the physical channel, which is belonging to the SBFD symbol or not. If the ratio of the number of transmission symbols belonging to the SBFD symbol in the M transmission symbols to M is greater than or equal to a preset ratio, it can be determined that the physical channel is a physical channel transmitted in the SBFD symbol; if the ratio of the number of transmission symbols belonging to the SBFD symbol in the M transmission symbols to M is less than the preset ratio, it can be determined that the physical channel is not a physical channel transmitted in the SBFD symbol. Wherein, the preset ratio is less than or equal to 1.

[0334] In the embodiment of the present application, the transmission symbol of the physical channel that does not belong to the SBFD symbol can include the case that the transmission symbol is a symbol without configured uplink subband, or it can represent the case that the transmission symbol is configured with uplink subband, but is fallbacked to non-SBFD symbol due to containing synchronization signal block (SS and PBCH Block, SSB).

[0335] In the above embodiment, how to determine whether the physical channel is a physical channel transmitted in the SBFD symbol is introduced. For the physical channel transmitted in the SBFD symbol, based on the frequency domain position of the target subband, the frequency domain resource used to transmit the physical channel can be determined in the activated BWP, which will be introduced in combination with the drawings.

[0336] Figure 4The flowchart provided by the embodiment of the present application for determining the frequency domain resource for transmitting a physical channel includes the following steps, as shown in Figure 4

[0337] S41, determining the starting RB of the target subband in the active BWP based on the frequency domain position of the target subband.

[0338] The starting RB of the target subband in the active BWP refers to the starting frequency domain position of the part of the target subband in the active BWP. The frequency domain position of the target subband in the SBFD symbol is certain, while the starting RB of the target subband in the active BWP is related to the relative frequency domain position between the active BWP and the target subband. Only the case where there is an overlap between the frequency domain resources of the target subband and the active BWP is discussed, and if the frequency domain resources of the target subband and the active BWP do not overlap, it is not within the scope of the present application.

[0339] In the case where the starting RB of the target subband is within the active BWP, the starting RB of the target subband in the active BWP is the starting RB of the target subband; in the case where the starting RB of the target subband is outside the active BWP, the starting RB of the target subband in the active BWP is the starting RB of the active BWP.

[0340] Specifically, in the case where the starting RB of the target subband is within the active BWP, the starting RB of the target subband belongs to a part of the active BWP, so the starting RB of the target subband is directly taken as the starting RB of the target subband in the active BWP. In the case where the starting RB of the target subband is outside the active BWP, the starting RB of the target subband does not belong to a part of the active BWP, so the starting RB of the active BWP is taken as the starting RB of the target subband in the active BWP.

[0341] The implementation process of how to determine the starting RB of the target subband in the active BWP is introduced below by taking the physical channel as PUSCH and the target subband as the uplink subband as an example.

[0342] Figure 5 The schematic diagram provided by the embodiment of the present application for determining the starting RB of the target subband in the active BWP is shown in Figure 5 , which illustrates how to determine the starting RB of the target subband in the active BWP in the case where the physical channel is PUSCH and the target subband is the uplink subband.

[0343] In Figure 5 , the active BWP and the uplink subband in two different cases are illustrated respectively.

[0344] ​In case one, if the starting frequency domain position of the uplink subband is within the active BWP, the starting frequency domain position of the uplink subband in the active BWP is the starting frequency domain position of the uplink subband, and the starting RB of the uplink subband in the active BWP (i.e., the RB where the starting frequency domain position of the uplink subband in the active BWP is located) is the starting RB of the uplink subband (i.e., the starting frequency domain position of the uplink subband).

[0345] In case two, if the starting frequency domain position of the uplink subband is outside the active BWP, the starting frequency domain position of the uplink subband in the active BWP is the starting frequency domain position of the active BWP, and the starting RB of the uplink subband in the active BWP (i.e., the RB where the starting frequency domain position of the uplink subband in the active BWP is located) is the starting RB of the active BWP (i.e., the RB where the starting frequency domain position of the active BWP is located). As shown in FIG. 3, the frequency domain resources within the uplink subband range but not within the active BWP are not considered. Figure 5

[0346] S42, based on the starting RB of the target subband in the active BWP and the VRB of the physical channel when mapping from the VRB to the physical resource block (PRB), determine the starting PRB of the frequency domain resource of the physical channel in the active BWP.

[0347] Optionally, the mapping from the VRB to the PRB is non-interleaved mapping, which is relative to interleaved mapping. Interleaved mapping is a way of mapping the VRB to the PRB after scrambling, and through this mapping, the originally logically continuous or discontinuous VRB is mapped to the dispersed PRB on the physical layer. Non-interleaved mapping is a more direct mapping way, and under the non-interleaved mapping way, there is a one-to-one correspondence between the VRB and the PRB, that is, the number of the VRB is directly mapped to the number of the PRB.

[0348] After determining the starting RB of the target subband in the active BWP, the starting PRB of the frequency domain resource of the physical channel in the active BWP can be determined in combination with the VRB of the physical channel when mapping from the VRB to the PRB.

[0349] Optionally, the starting PRB of the frequency domain resource of the physical channel in the active BWP satisfies any one of 2.1 to 2.3 below:

[0350] 2.1, d = n + k1;

[0351] 2.2, d = n + k2-p;

[0352] 2.3, d = n + k3-q-p;

[0353] Wherein, d is the number of the starting PRB of the frequency domain resource of the physical channel in the active BWP.​

[0354] n is the number of VRB of the physical channel when mapping from VRB to PRB; k1 is the number of starting RB of target subband in active BWP relative to the number of starting RB of active BWP;

[0355] k2 is the number of starting RB of target subband in active BWP relative to the number of starting RB of carrier; p is the number of starting RB of active BWP relative to the number of starting RB of carrier;

[0356] k3 is the number of starting RB of target subband in active BWP relative to the number of starting RB of point A; q is the number of starting RB of carrier relative to the number of starting RB of point A.

[0357] Point A is a common reference point of resource block grid, and point A can be determined according to a parameter offsetToPointA or a parameter absoluteFrequencyPointA, wherein the parameter offsetToPointA represents a frequency difference between point A and a lowest point in frequency domain, indicates a relative frequency domain position of point A, and the parameter absoluteFrequencyPointA represents an absolute frequency domain position of point A.

[0358] In item 2.1, the number of starting RB of target subband in active BWP is referenced to the starting RB position of active BWP, to obtain the number k1 of starting RB of target subband in active BWP relative to the starting RB of active BWP, wherein k1 also represents the number of RBs included between the starting RB of active BWP and the starting RB of target subband in active BWP.

[0359] In item 2.2, the number of starting RB of target subband in active BWP is referenced to the starting RB position of carrier, to obtain the number k2 of starting RB of target subband in active BWP relative to the starting RB of carrier, wherein k2 also represents the number of RBs included between the starting RB of carrier and the starting RB of target subband in active BWP. The number of starting RB of active BWP is also referenced to the starting RB position of carrier, to obtain the number p of starting RB of active BWP relative to the starting RB of carrier, wherein p also represents the number of RBs included between the starting RB of carrier and the starting RB of active BWP.

[0360] In item 2.3, the number of the starting RB of the target sub-band in the active BWP is referenced to the starting RB position of the point A, to obtain the number k3 of the starting RB of the target sub-band in the active BWP relative to the starting RB of the point A, wherein k3 also represents the number of RBs included between the starting RB of the point A and the starting RB of the target sub-band in the active BWP. The number of the starting RB of the carrier is also referenced to the starting RB position of the point A, to obtain the number q of the starting RB of the carrier relative to the starting RB of the point A, wherein q also represents the number of RBs included between the starting RB of the point A and the starting RB of the carrier. The meaning of q is the same as that in item 2.2, which will not be described here.

[0361] Based on any one of items 2.1 to 2.3, the number d of the starting PRB of the frequency domain resource of the physical channel in the active BWP can be determined, that is, the starting PRB of the frequency domain resource of the physical channel in the active BWP is determined.

[0362] In item S43, the frequency domain resource of the physical channel is determined in the active BWP based on the starting PRB of the frequency domain resource of the physical channel in the active BWP.

[0363] After the starting PRB of the frequency domain resource of the physical channel in the active BWP is determined, the starting PRB of the frequency domain resource of the physical channel in the active BWP can be used as the starting position to determine the frequency domain resource of the physical channel in the active BWP.

[0364] The starting PRB of the frequency domain resource of the physical channel in the active BWP only indicates the starting position of the frequency domain resource of the physical channel, and the size of the frequency domain resource of the physical channel also needs to be combined to determine the frequency domain resource of the physical channel. The size of the frequency domain resource of the physical channel needs to be determined by combining high-layer signaling configuration or DCI indication, etc.

[0365] The physical channel can be a PUSCH. Optionally, the PUSCH is a PUSCH scheduled by DCI format 0_0. The FDRA size of DCI format 0_0 depends on the initial uplink BWP.

[0366] Optionally, in the case where the physical channel is a PUSCH scheduled by DCI format 0_0, the terminal determines the frequency domain resource used to transmit the PUSCH based on the method of the embodiments of the present application, and sends the PUSCH to the network device based on the determined frequency domain resource. Correspondingly, the network device determines the frequency domain resource used to transmit the PUSCH based on the method of the embodiments of the present application, and receives the PUSCH sent by the terminal based on the determined frequency domain resource.

[0367] Optionally, the PUSCH meets at least one of the following 3.1 to 3.3:

[0368] 3.1. PUSCH is the PUSCH scheduled by DCI format 0_0 in the common search space CSS;

[0369] 3.2. PUSCH is the PUSCH scheduled by DCI format 0_0 in the user-specific search space USS;

[0370] 3.3. The PUSCH is a PUSCH scheduled in the USS using DCI format 0_0, whose DCI size is determined according to DCI format 0_0 in the CSS.

[0371] Optionally, when the physical channel is a PUSCH and at least one of 3.1 to 3.3 above is met, the terminal determines the frequency domain resources for transmitting the PUSCH based on the method of the embodiment of the present application, and sends the PUSCH to the network device based on the determined frequency domain resources. Correspondingly, the network device determines the frequency domain resources for transmitting the PUSCH based on the method of the embodiment of the present application, and receives the PUSCH sent by the terminal based on the determined frequency domain resources.

[0372] The physical channel may be a PDSCH, optionally a PDSCH scheduled by DCI format 1_0. The FDRA size of DCI format 1_0 depends on different conditions. If the carrier is configured with CORESET 0, the FDRA size of DCI format 1_0 depends on the bandwidth of CORESET 0. If the carrier is not configured with CORESET 0, the FDRA size of DCI format 1_0 depends on the initial downlink BWP.

[0373] Optionally, in the case where the physical channel is a PDSCH scheduled by DCI format 1_0, the network device determines the frequency domain resources for transmitting the PDSCH based on the method of the embodiment of the present application, and sends the PDSCH to the terminal based on the determined frequency domain resources. Correspondingly, the terminal determines the frequency domain resources for transmitting the PDSCH based on the method of the embodiment of the present application, and receives the PDSCH sent by the network device based on the determined frequency domain resources.

[0374] Optionally, the PDSCH meets at least one of the following 4.1 to 4.3:

[0375] 4.1. PDSCH is the PDSCH scheduled by DCI format 1_0 in CSS;

[0376] 4.2. PDSCH is the PDSCH scheduled by DCI format 1_0 in USS;

[0377] 4.3, PDSCH is USS, DCI format 1_0 in CSS determines the size of DCI format 1_0 scheduling PDSCH.

[0378] Optionally, in the case of physical channel being PDSCH and at least one of the above 4.1 to 4.3 being met, the network device determines the frequency domain resource used for transmitting the PDSCH based on the method of the embodiments of the application, and sends the PDSCH to the terminal based on the determined frequency domain resource. Correspondingly, the terminal determines the frequency domain resource used for transmitting the PDSCH based on the method of the embodiments of the application, and receives the PDSCH sent by the network device based on the determined frequency domain resource.

[0379] Wherein, the determination method of the size of the frequency domain resource of the physical channel can refer to the related description in the above embodiments. For example, for PUSCH scheduled by DCI format 0_0 in CSS, the size of the frequency domain resource is equal to the bandwidth of the initial uplink BWP. For example, for PDSCH scheduled by DCI format 1_0 in CSS, when the carrier is configured with CORESET 0, the size of the frequency domain resource is equal to the bandwidth of CORESET 0, otherwise the size of the frequency domain resource is equal to the bandwidth of the initial downlink BWP. For example, in some cases (when the DCI size exceeds the limit of 3+1, that is, the number of DCI sizes that the terminal needs to blind detect exceeds 3 special DCI sizes and 1 common DCI size), DCI format 0_0 and DCI format 0_1 in USS also use the same way as in CSS to determine the size of the frequency domain resource, and so on.

[0380] Optionally, for PDSCH transmission in SBFD symbols scheduled by DCI format 1_0 in CSS, the network device can avoid the problem of being unable to determine the effective PDSCH transmission resource by configuring the starting RB of the CORESET resource within the downlink sub-band range.

[0381] In the above embodiments, the scheme of the application is described in detail, and the scheme of the embodiments of the application will be described below with PUSCH and PDSCH as examples.

[0382] First, the implementation scheme of how to determine the frequency domain resource in the case of PUSCH transmission is introduced. Figure 6-8

[0383] Figure 6 The implementation scheme of how to determine the frequency domain resource in the case of PUSCH transmission is introduced. Figure 1 For example, Figure 6 ​The frequency domain range of the activated uplink BWP (i.e., the frequency domain range between frequency domain position B and frequency domain position C in Figure 6 ) and the frequency domain range of the uplink sub-band (i.e., the frequency domain range between frequency domain position D and frequency domain position E in Figure 6 ) are shown in the SBFD symbol.

[0384] Firstly, the starting RB of the uplink sub-band in the activated uplink BWP needs to be determined. In the example of Figure 6 , the starting RB of the uplink sub-band is within the activated uplink BWP, so the starting RB of the uplink sub-band in the activated uplink BWP is the starting RB of the uplink sub-band, and the corresponding frequency domain position is Figure 6 frequency domain position D in

[0385] The starting RB of the uplink sub-band in the activated uplink BWP is determined by the number of the starting RB of the activated uplink BWP, and the number k1 of the starting RB of the activated uplink BWP relative to the starting RB of the uplink sub-band is taken as an example, as shown in Figure 6 , that is, it means that there are 35 RBs between frequency domain position B and frequency domain position D. Taking the number n = 3 of the VRB of the physical channel when mapping from VRB to PRB as an example, it can be known based on item 2.1 in the above embodiment that the starting PRB number d of the frequency domain resource of the PUSCH in the activated uplink BWP is n + k1 = 3 + 35 = 38.

[0386] The starting position of the frequency domain resource of the PUSCH can be determined based on the starting PRB number d of the frequency domain resource of the PUSCH in the activated uplink BWP, and the frequency domain resource for transmitting the PUSCH can be determined in combination with the size of the frequency domain resource of the PUSCH, that is, the frequency domain range indicated by the FDRA in Figure 6 , that is, the frequency domain range between frequency domain position H and frequency domain position F in Figure 6 . Among them, the number of RBs between frequency domain position D and frequency domain position H is n, that is, 3 RBs.

[0387] It can be known based on Figure 6 that the scheme of the embodiment of the present application determines the number of the starting RB of the uplink sub-band in the activated uplink BWP relative to the starting RB of the activated uplink BWP by taking the starting RB of the activated uplink BWP as the reference position for the transmission of the PUSCH, and determines the starting PRB of the frequency domain resource of the PUSCH in the activated uplink BWP by combining the number of the VRB of the physical channel when mapping from VRB to PRB, which can determine the effective frequency domain resource for transmitting the PUSCH in the uplink sub-band, thereby effectively scheduling the transmission of the PUSCH.

[0388] Figure 6 The schematic diagram for determining the frequency domain resource for transmitting the PUSCH provided by the embodiment of the present application is shown in Figure 7,like Figure 2 As shown, the frequency domain range of the activated uplink BWP is shown in the SBFD symbol (i.e. Figure 7 The frequency domain range between the frequency domain position B and the frequency domain position C in the uplink subband (i.e. Figure 7 The frequency domain range between frequency domain position D and frequency domain position E in FIG.

[0389] First, it is necessary to determine the starting RB of the uplink subband in the activated uplink BWP. Figure 7 In the example, the starting RB of the uplink subband is within the activated uplink BWP. Therefore, the starting RB of the uplink subband in the activated uplink BWP is the starting RB of the uplink subband, and the corresponding frequency domain position is Figure 7 The frequency domain position D in .

[0390] The starting RB of the uplink subband in the activated uplink BWP is numbered with the starting RB of the carrier. For example, if the starting RB of the uplink subband in the activated uplink BWP is numbered k2 relative to the starting RB of the carrier, it is 60. Figure 7 As shown in , it means that there are 60 RBs between frequency domain position G and frequency domain position D. Take the case where the number p of the starting RB for activating uplink BWP relative to the starting RB of the carrier is 25 as an example. Figure 7 As shown, this means that there are 25 RBs between frequency domain position G and frequency domain position B. Taking the VRB number n=3 of the physical channel when mapping from VRB to PRB as an example, based on item 2.2 of the above embodiment, it can be seen that the starting PRB number of the PUSCH frequency domain resource in the activated uplink BWP is d=n+k2-p=3+60-25=38.

[0391] The starting position of the frequency domain resource based on the PUSCH frequency domain resource in the activated uplink BWP can be determined. Combined with the size of the PUSCH frequency domain resource, the frequency domain resource used to transmit the PUSCH can be determined, that is, Figure 7 The frequency domain range indicated by FDRA in Figure 7 The frequency domain range between the frequency domain position H and the frequency domain position F in . The number of RBs included between the frequency domain position D and the frequency domain position H is n, that is, 3 RBs.

[0392] Combine Figure 7 It can be seen that the solution of the embodiment of the present application, for the transmission of PUSCH, uses the starting RB of the carrier as a reference position to determine the number of the starting RB of the uplink subband in the activated uplink BWP relative to the starting RB of the carrier, and combines the number of the VRB of the physical channel when mapping from VRB to PRB to determine the starting PRB of the frequency domain resources of PUSCH in the activated uplink BWP. It can determine the effective frequency domain resources for transmitting PUSCH in the uplink subband, thereby effectively scheduling the transmission of PUSCH.

[0393] Figure 7 The embodiment provided in the present application determines the frequency domain resource for transmitting the PUSCH Figure 8 As shown in the SBFD symbol, the frequency domain range of the activated uplink BWP (i.e. the frequency domain range between the frequency domain position B and the frequency domain position C in the SBFD symbol) and the frequency domain range of the uplink sub-band (i.e. the frequency domain range between the frequency domain position D and the frequency domain position E in the SBFD symbol) are shown. Figure 3 Figure 8 Firstly, the starting RB of the uplink sub-band in the activated uplink BWP needs to be determined. Figure 8 In the example of FIG. 8, the starting RB of the uplink sub-band is within the activated uplink BWP, so the starting RB of the uplink sub-band in the activated uplink BWP is the starting RB of the uplink sub-band, and the corresponding frequency domain position is the frequency domain position D in the SBFD symbol.

[0394] The starting RB of the uplink sub-band in the activated uplink BWP is determined by the starting RB of the point A, and the number k3 of the starting RB of the uplink sub-band in the activated uplink BWP relative to the starting RB of the point A is taken as an example, as shown in FIG. 8, that is, it means that there are 84 RBs between the frequency domain position I and the frequency domain position D. The number p of the starting RB of the activated uplink BWP relative to the starting RB of the carrier is taken as an example, as shown in FIG. 8, that is, it means that there are 25 RBs between the frequency domain position G and the frequency domain position B. The number q of the starting RB of the carrier relative to the starting RB of the point A is taken as an example, as shown in FIG. 8, that is, it means that there are 24 RBs between the frequency domain position I and the frequency domain position G. Figure 8 Figure 8

[0395] The starting RB of the uplink sub-band in the activated uplink BWP is determined by the starting RB of the point A, and the number k3 of the starting RB of the uplink sub-band in the activated uplink BWP relative to the starting RB of the point A is taken as an example, as shown in FIG. 8, that is, it means that there are 84 RBs between the frequency domain position I and the frequency domain position D. The number p of the starting RB of the activated uplink BWP relative to the starting RB of the carrier is taken as an example, as shown in FIG. 8, that is, it means that there are 25 RBs between the frequency domain position G and the frequency domain position B. The number q of the starting RB of the carrier relative to the starting RB of the point A is taken as an example, as shown in FIG. 8, that is, it means that there are 24 RBs between the frequency domain position I and the frequency domain position G. Figure 8 Figure 8 Figure 8

[0396] The number n of the VRB of the physical channel when mapping from the VRB to the PRB is taken as an example, and based on item 2.3 in the above embodiment, the starting PRB number d of the frequency domain resource of the PUSCH in the activated uplink BWP is n+k3-q-p=3+84-24-25=38.

[0397] Based on the starting PRB number d of the frequency domain resource of the PUSCH in the activated uplink BWP, the starting position of the frequency domain resource can be determined, and in combination with the size of the frequency domain resource of the PUSCH, the frequency domain resource for transmitting the PUSCH can be determined, that is, the frequency domain range indicated by the FDRA in the SBFD symbol, that is, the frequency domain range between the frequency domain position H and the frequency domain position F in the SBFD symbol. Among them, the number of RBs between the frequency domain position D and the frequency domain position H is n, that is, 3 RBs. Figure 8 Figure 8

[0398] ​​​​​​​​In combination Figure 8 It can be known that, according to the scheme of the embodiment of the application, for the transmission of the PUSCH, the starting RB of the point A is taken as a reference position to determine the number of the starting RB of the uplink sub-band in the activated uplink BWP relative to the starting RB of the point A, and the frequency domain resource of the PUSCH in the activated uplink BWP is determined in combination with the number of the VRB of the physical channel in the mapping from the VRB to the PRB, so that the effective frequency domain resource for transmitting the PUSCH can be determined in the uplink sub-band, thereby effectively scheduling the transmission of the PUSCH.

[0399] It should be noted that, in Figure 8 In the embodiments, the starting RB of the uplink sub-band is taken as an example in the activated uplink BWP, and in other embodiments, the starting RB of the uplink sub-band is not in the activated uplink BWP, at this time, the scheme for determining the starting RB of the uplink sub-band in the activated uplink BWP can be determined according to the scheme of the embodiment of the application, and other processes remain unchanged, which will not be described here. Figure 6-8

[0400] In the above embodiments, the implementation scheme of how to determine the frequency domain resource in combination with Figure 5 The implementation scheme of how to determine the frequency domain resource in the case of PUSCH transmission is introduced, and the implementation scheme of how to determine the frequency domain resource in the case of PDSCH transmission is introduced below in combination with Figure 6-8 .

[0401] For the SBFD terminal, when the network device schedules the PDSCH transmitted in the SBFD symbol through the DCI format 1_0 in the CSS, the network device needs to ensure that the starting RB resource of the CORESET corresponding to the DCI is in the range of the downlink sub-band, or for the PDSCH in the SBFD symbol, the frequency domain resource of the PDSCH is determined based on the frequency domain position of the downlink sub-band. Figure 9-12 The starting RB position diagram of the CORESET provided for the embodiment of the application is shown in FIG. 1, as shown in FIG. 1, the SBFD symbol includes an uplink sub-band and a downlink sub-band. For case A, the starting RB of the CORESET is in the range of the downlink sub-band; for case B, the starting RB of the CORESET is in the range of the uplink sub-band. Figure 9

[0402] Figure 9 The schematic diagram for determining the frequency domain resource for transmitting the PDSCH provided for the embodiment of the application is shown in FIG. 2, as shown in FIG. 2, the frequency domain range of the activated downlink BWP (that is, the frequency domain range between the frequency domain position J and the frequency domain position K in FIG. 2) and the frequency domain range of the downlink sub-band (that is, the frequency domain range between the frequency domain position L and the frequency domain position K in FIG. 2) are shown in the SBFD symbol. Figure 10 Figure 1 Figure 10 Figure 10

[0403] ​​​​​​Firstly, the starting RB of the downlink sub-band in the active downlink BWP needs to be determined. Figure 10 In the example, the starting RB of the downlink sub-band is within the active downlink BWP, so the starting RB of the downlink sub-band in the active downlink BWP is the starting RB of the downlink sub-band, and the corresponding frequency domain position is Figure 10 the frequency domain position L in the above formula.

[0404] The starting RB of the downlink sub-band in the active downlink BWP is determined by the number of the starting RB of the active downlink BWP, and the number k1 of the starting RB of the active downlink BWP relative to the starting RB of the downlink sub-band in the active downlink BWP is taken as an example, as shown in Figure 10 , which means that there are 30 RBs between the frequency domain position J and the frequency domain position L. Taking the number n = 15 of the VRB of the physical channel when mapping from the VRB to the PRB as an example, it can be known based on item 2.1 in the above embodiment that the starting PRB of the frequency domain resource of the PDSCH in the active downlink BWP is d = n + k1 = 15 + 30 = 45.

[0405] The starting position of the frequency domain resource of the PDSCH can be determined based on the number d of the starting PRB of the frequency domain resource of the PDSCH in the active downlink BWP, and the frequency domain resource used for transmitting the PDSCH can be determined in combination with the size of the frequency domain resource of the PDSCH, that is, Figure 10 the frequency domain range indicated by the FDRA in the above formula, that is, Figure 10 the frequency domain range between the frequency domain position N and the frequency domain position O in the above formula. The number of RBs included between the frequency domain position L and the frequency domain position N is n, that is, 15 RBs.

[0406] It can be known based on Figure 10 that, in the scheme of the embodiment of the present application, the number of the starting RB of the downlink sub-band in the active downlink BWP relative to the starting RB of the active downlink BWP is determined by taking the starting RB of the active downlink BWP as the reference position, the starting PRB of the frequency domain resource of the PDSCH in the active downlink BWP is determined in combination with the number of the VRB of the physical channel when mapping from the VRB to the PRB, the effective frequency domain resource used for transmitting the PDSCH can be determined in the downlink sub-band, and the transmission of the PDSCH can be effectively scheduled.

[0407] Figure 10 The schematic diagram for determining the frequency domain resource used for transmitting the PDSCH provided by the embodiment of the present application is shown in Figure 11 , as shown in Figure 2 , the frequency domain range of the active downlink BWP (that is, the frequency domain range between the frequency domain position J and the frequency domain position K in the above formula) and the frequency domain range of the downlink sub-band (that is, the frequency domain range between the frequency domain position L and the frequency domain position K in the above formula) are shown in the SBFD symbol. Figure 11 Figure 11 ​​

[0408] First, it is necessary to determine the starting RB of the downlink subband in the activated downlink BWP. Figure 11 In the example, the starting RB of the downlink subband is within the activated downlink BWP. Therefore, the starting RB of the downlink subband in the activated downlink BWP is the starting RB of the downlink subband, and the corresponding frequency domain position is Figure 11 The frequency domain position L in .

[0409] The starting RB of the downlink subband in the activated downlink BWP is numbered with the starting RB of the carrier. For example, the starting RB of the downlink subband in the activated downlink BWP relative to the starting RB of the carrier is numbered k2 as 40. Figure 11 As shown, it means that there are 40 RBs between the frequency domain position P and the frequency domain position L. For example, if the number p of the starting RB of the activated downlink BWP relative to the starting RB of the carrier is 10, Figure 11 As shown, this means that there are 10 RBs between frequency domain position P and frequency domain position J. Taking the VRB number n=15 of the physical channel when mapping from VRB to PRB as an example, based on item 2.2 of the above embodiment, it can be seen that the starting PRB number of the PDSCH frequency domain resource in the activated downlink BWP is d=n+k2-p=15+40-10=45.

[0410] The starting position of the frequency domain resource based on the PDSCH frequency domain resource in the activated downlink BWP can be determined. Combined with the size of the PDSCH frequency domain resource, the frequency domain resource used to transmit the PDSCH can be determined, that is, Figure 11 The frequency domain range indicated by FDRA in Figure 11 The frequency domain range between the frequency domain position N and the frequency domain position O in . The number of RBs included between the frequency domain position L and the frequency domain position N is n, that is, 15 RBs.

[0411] Combine Figure 11 It can be seen that the solution of the embodiment of the present application, for the transmission of PDSCH, uses the starting RB of the carrier as a reference position to determine the number of the starting RB of the downlink subband in the activated downlink BWP relative to the starting RB of the carrier, and combines the number of the VRB of the physical channel when mapping from VRB to PRB to determine the starting PRB of the frequency domain resources of PDSCH in the activated downlink BWP. It can determine the effective frequency domain resources for transmitting PDSCH in the downlink subband, thereby effectively scheduling the transmission of PDSCH.

[0412] Figure 11 Schematic diagram of determining frequency domain resources for transmitting PDSCH provided in an embodiment of the present application Figure 12 ,like Figure 3 As shown, the frequency domain range of the activated downlink BWP is shown in the SBFD symbol (ieFigure 12 the frequency domain range between the frequency domain location J to the frequency domain location K in the frequency domain range of the downlink sub-band, i.e. Figure 12 the frequency domain range between the frequency domain location L to the frequency domain location K in the frequency domain range of the downlink sub-band.

[0413] Firstly, the starting RB of the downlink sub-band in the activated downlink BWP needs to be determined. In the example of Figure 12 , the starting RB of the downlink sub-band is within the activated downlink BWP, thus the starting RB of the downlink sub-band in the activated downlink BWP is the starting RB of the downlink sub-band, and the corresponding frequency domain location is Figure 12 the frequency domain location L in the frequency domain range of the downlink sub-band.

[0414] The starting RB of the downlink sub-band in the activated downlink BWP is determined by the starting RB of the point A, and the number k3 of the starting RB of the downlink sub-band in the activated downlink BWP relative to the starting RB of the point A is taken as 50 for example, as shown in Figure 12 , which means that the frequency domain range between the frequency domain location Q to the frequency domain location L includes 50 RBs. The number p of the starting RB of the activated downlink BWP relative to the starting RB of the carrier is taken as 10 for example, as shown in Figure 12 , which means that the frequency domain range between the frequency domain location P to the frequency domain location J includes 10 RBs. The number q of the starting RB of the carrier relative to the starting RB of the point A is taken as 10 for example, as shown in Figure 12 , which means that the frequency domain range between the frequency domain location Q to the frequency domain location P includes 10 RBs.

[0415] The number n of the VRB of the physical channel when mapping from the VRB to the PRB is taken as 15 for example, thus based on item 2.3 in the above embodiment, the number d of the starting PRB of the frequency domain resource of the PUSCH in the activated downlink BWP is n+k3-q-p=15+50-10-10=45.

[0416] The number d of the starting PRB of the frequency domain resource of the PDSCH in the activated downlink BWP can determine the starting location of the frequency domain resource, and in combination with the size of the frequency domain resource of the PDSCH, the frequency domain resource for transmitting the PDSCH can be determined, i.e. Figure 12 the frequency domain range indicated by the FDRA in the frequency domain range of the PDSCH, i.e. Figure 12 the frequency domain range between the frequency domain location N to the frequency domain location O in the frequency domain range of the PDSCH. Wherein, the number of RBs included between the frequency domain location L to the frequency domain location N is n, i.e. 15 RBs.

[0417] In combination with Figure 12It can be known that, according to the scheme of the embodiment of the present application, for the transmission of the PDSCH, the starting RB of the point A is taken as a reference position to determine the number of the starting RB of the downlink subband in the activated downlink BWP relative to the starting RB of the point A, and the starting PRB of the frequency domain resource of the PDSCH in the activated downlink BWP is determined in combination with the number of the VRB of the physical channel when mapping from the VRB to the PRB, so that the effective frequency domain resource for transmitting the PDSCH can be determined in the downlink subband, thereby effectively scheduling the transmission of the PDSCH.
