Technical Field

[0003] In 5G New Radio (NR), to improve the uplink coverage of the Time Division Duplex (TDD) system, the Subband Non-Overlapping Full Duplex (SBFD) technology is proposed. That is, network equipment and terminals can simultaneously transmit and receive through uplink and downlink subbands within a TDD carrier.

[0004] In related technologies, the frequency domain resources of a physical channel are usually determined based on the initial bandwidth part (BWP), the activated BWP, or the starting resource block (RB) of the control resource set (CORESET) where the downlink control information (DCI) is located. However, this frequency domain resource determination method may cause the frequency domain resources used to transmit the physical channel to not match the subband corresponding to the transmission direction in the current activated BWP, making it impossible to schedule data transmission in the uplink subband or downlink subband.

For example, Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), and other devices. The wireless terminal device may also be referred to as a system, a subscriber unit, a subscriber station, a mobile station, a mobile station, a remote station, an access point, a remote terminal device, an access terminal device, a user terminal device, a user agent, or a user device, but is not limited in the embodiments of the present disclosure.

[0209] The network device involved in the embodiments of the present disclosure may be a base station, which may include multiple cells providing services to terminals. Depending on the specific application scenario, the base station may also be called an access point, or may be a device in an access network that communicates with a wireless terminal device through one or more sectors on an air interface, or may be called another name. The network device may be used to interchange received air frames with Internet Protocol (IP) packets, acting as a router between the wireless terminal device and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) communication network. The network device may also coordinate the attribute management of the air interface. For example, the network device involved in the embodiments of the present disclosure may be a base transceiver station (BTS) in the Global System for Mobile communications (GSM) or code division multiple access (CDMA), a network device (NodeB) in wide-band code division multiple access (WCDMA), an evolutionary Node B (eNB or e-NodeB) in the long term evolution (LTE) system, a 5G base station (gNB) in the 5G network architecture (next generation system), a home evolved Node B (HeNB), a relay node, a femto, a pico, etc., and is not limited in the embodiments of the present disclosure. In some network structures, the network device may include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and the distributed unit may also be geographically separated.

[0210] Network devices and terminal devices can each use one or more antennas for Multiple Input Multiple Output (MIMO) transmission. MIMO transmission can be single-user MIMO (SU-MIMO) or multi-user MIMO (MU-MIMO). Depending on the form and number of antenna combinations, MIMO transmission can be 2D-MIMO, 3D-MIMO, FD-MIMO, or massive-MIMO. It can also use diversity transmission, precoding transmission, or beamforming transmission.

[0211] 5G NR supports two duplex communication modes: TDD and Frequency Division Duplex (FDD). TDD mode supports transmission and reception at different times on the same frequency channel, i.e., the carrier, distinguishing uplink and downlink transmission resources by time; FDD mode supports simultaneous transmission and reception on different frequency channels, distinguishing uplink and downlink transmission resources by frequency.

[0212] 5G NR will support SBFD mode in the Rel-19 stage, that is, network equipment and terminals can simultaneously transmit and receive through different subbands within a TDD carrier, and the subbands used for transmission and reception do not overlap.

[0213] SBFD mode is implemented based on SBFD symbols. An SBFD symbol contains both an uplink subband for uplink transmission and a downlink subband for downlink transmission. That is, it includes both uplink and downlink frequency domain resources in the frequency domain. Currently, SBFD symbols can be configured in downlink symbols or flexible symbols configured in TDD-UL-DL-ConfigCommon. For subband full-duplex systems, two subband configurations are currently supported: SBFD subband configuration 1 and SBFD subband configuration 2. These two subband configurations are described below with reference to Figure 1.

[0214] FIG1 is a schematic diagram of subband configuration supported in a subband full-duplex system. As shown in FIG1 , for an SBFD symbol, it includes one SBFD time slot in the time domain and includes an uplink subband and a downlink subband in the frequency domain.

[0215] Please refer to Figure 1. For SBFD subband configuration 1, it uses the {DUD} mode (D represents downlink and U represents uplink), that is, one SBFD symbol contains one uplink subband and two downlink subbands. The uplink subband is located at the center of the carrier bandwidth, and the two downlink subbands are located on both sides of the carrier bandwidth; for SBFD subband configuration 2, it uses the {DU} mode, that is, one SBFD symbol contains one uplink subband and one downlink subband. The uplink subband is located on one side of the carrier bandwidth, and the downlink subband is located on the other side of the carrier bandwidth.

[0216] In the above embodiment, the SBFD symbol subband configuration is introduced in conjunction with FIG1 . The following describes a method for determining the frequency domain resource allocation (FDRA) in the downlink control information (DCI).

[0217] DCI-scheduled transmissions can include the Physical Uplink Shared Channel (PUSCH) and the Physical Downlink Shared Channel (PDSCH). DCI can have multiple formats, such as DCI format 0_0 and DCI format 1_0. DCI format 0_0 is primarily used to schedule PUSCH transmissions, while DCI format 1_0 is primarily used to schedule PDSCH transmissions.

[0218] The FDRA size of DCI format 0_0 in the common search space (CSS) depends on the initial uplink (initial UL) BWP. For PUSCH scheduled by DCI format 0_0 in the CSS, the schedulable bandwidth is equal to the bandwidth of the initial uplink BWP, and RB numbering starts based on the lowest RB corresponding to the activated uplink BWP.

[0219] When a carrier is configured with CORESET 0, the size of the FDRA in DCI format 1_0 in the CSS depends on the bandwidth of CORESET 0. Otherwise, it depends on the bandwidth of the initial downlink (BWP). A CORESET is a resource set used to transmit the Physical Downlink Control Channel (PDCCH). DCI is transmitted via the PDCCH and needs to indicate all possible PDSCH resource locations within the CORESET 0 bandwidth. Therefore, the bandwidth of CORESET 0 directly affects the size of the FDRA in DCI format 1_0.

[0220] For PDSCHs scheduled with DCI format 1_0 in the CSS, RB numbering starts from the lowest RB corresponding to the CORESET in which 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 the initial downlink BWP.

[0221] In some cases (when the DCI size exceeds the limit of 3+1, that is, when the number of DCI sizes that the terminal needs to blindly detect exceeds 3 dedicated DCI sizes and 1 common DCI size), DCI format 0_0 and DCI format 0_1 ​​in the user-specific search space (UE-specific Search Space, USS) will also use the same method as in CSS to determine the size of FDRA.

[0222] For PUSCH scheduled by DCI format 0_0 in USS and PDSCH scheduled by DCI format 1_0, if the FDRA size of DCI in USS is the same as the FDRA size of DCI in CSS, but the scheduled PUSCH / PDSCH transmission is in an activated uplink BWP / activated downlink BWP, the frequency domain resource allocation is performed with K as the granularity. The indicated frequency domain resource starting position The length of a continuous virtual resource block (VRB) is Indicates the number of RBs in the initial BWP, Indicates the number of RBs that activate BWP. When K satisfies The maximum value in the set {1,2,4,8}, otherwise K=1.

[0223] The above embodiments describe how to determine the frequency domain resources for the DCI-scheduled PUSCH / PDSCH. For SBFD symbols in the Rel-19 SBFD system, uplink transmission is supported only in the uplink subband and downlink reception is supported only in the downlink subband. In some cases, it may not be possible to indicate resources within the subband for transmissions scheduled with DCI format 0_0 or DCI format 1_0.

[0224] A specific example is used for the description. FIG2 is a schematic diagram of determining frequency domain resources for a PUSCH. As shown in FIG2 , the example is a PUSCH transmission scheduled by DCI format 0_0.

[0225] Based on the above embodiment, it can be seen that for PUSCH scheduled by DCI format 0_0 in the CSS, the schedulable bandwidth is equal to the bandwidth of the initial uplink BWP, and RB numbering is performed 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 illustrated. When the uplink subband in the SBFD symbol is outside the frequency domain range indicated by the FDRA, PUSCH transmission cannot be scheduled.

[0226] Figure 2 takes the PUSCH transmission scheduled by DCI format 0_0 in the CSS as an example to illustrate the situation where PUSCH transmission cannot be scheduled when the uplink subband in the SBFD symbol is outside the frequency domain range indicated by FDRA. In some embodiments, if the FDRA size of the DCI in the USS is the same as the FDRA size of the DCI in the CSS, and the frequency domain range indicated by the FDRA contained in the DCI format 0_0 in the USS is equal to the bandwidth of the initial uplink BWP, when the uplink subband in the SBFD symbol is outside the frequency domain range indicated by FDRA, PUSCH transmission cannot be scheduled. The process for PDSCH transmission is similar and will not be repeated here.

[0227] 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-mentioned frequency domain resource determination method may cause the corresponding uplink subband / downlink subband to be outside the frequency domain range indicated by FDRA, and the transmission of the corresponding physical channel cannot be scheduled.

[0228] Based on the above technical problems, the embodiments of the present disclosure provide a method, device and storage medium for determining frequency domain resources. The solutions of the embodiments of the present disclosure will be described below with reference to the accompanying drawings.

[0229] FIG3 is a flow chart of a method for determining frequency domain resources according to an embodiment of the present disclosure. As shown in FIG3 , the method includes:

[0230] S31, for a physical channel transmitted in an SBFD symbol, determine, in an activated BWP, frequency domain resources for transmitting the physical channel based on the frequency domain position of a target subband; wherein the target subband is a subband in the SBFD symbol that matches the transmission direction of the physical channel.

[0231] The solution of the embodiment of the present disclosure can be applied to a wireless communication system, involving interaction between a terminal and a network device, and transmission of a physical channel between the terminal and the network device.

[0232] The execution entity of each embodiment of the present disclosure may be a terminal or a network device. If the execution entity is a terminal, the terminal transmits the physical channel with the network device by determining the frequency domain resources used for transmitting the physical channel; if the execution entity is a network device, the network device transmits the physical channel with the terminal by determining the frequency domain resources used for transmitting the physical channel.

[0233] For example, if the physical channel is a PUSCH, the terminal sends the PUSCH to the network device by determining the frequency domain resources used to transmit the PUSCH, and the network device receives the PUSCH sent by the terminal by determining the frequency domain resources used to transmit the PUSCH. For example, if the physical channel is a PDSCH, the network device sends the PDSCH to the terminal by determining the frequency domain resources used to transmit the PDSCH, and the terminal receives the PDSCH sent by the network device by determining the frequency domain resources used to transmit the PDSCH.

[0234] Optionally, the terminals in various embodiments of the present disclosure may be SBFD terminals. An SBFD terminal is a terminal that supports SBFD. An SBFD-supporting terminal is one that is aware of the SBFD subband configuration, or is aware that the access network device performs SBFD operations, or is a terminal running a later version. A terminal that does not support SBFD is one that is unaware of the SBFD subband configuration, or is unaware that the access network device performs SBFD operations, or is a terminal running an earlier version.

[0235] SBFD symbols include uplink and downlink subbands, with the uplink subband supporting uplink transmission and the downlink subband supporting downlink transmission. The target subband is the 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.

[0236] An active BWP is a type of BWP. In wireless networks, the carrier bandwidth can be divided into a set of contiguous common RBs, which form a BWP. A BWP is a subset of the cell bandwidth. The active BWP is the operating bandwidth used by a terminal, and the terminal performs physical channel transmission within the active BWP.

[0237] In an embodiment of the present disclosure, for the physical channel transmitted in the SBFD symbol, the terminal determines the frequency domain resources used to transmit the physical channel in the activated BWP based on the frequency domain position of the target subband. Since the frequency domain resources used to transmit the physical channel are 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 scheduled normally.

[0238] The frequency domain resource determination method provided by the embodiments of the present disclosure determines, for a physical channel transmitted in an SBFD symbol, the frequency domain resources used to transmit the physical channel in the active BWP based on the frequency domain position of the target subband. The target subband is the subband in the SBFD symbol that matches the transmission direction of the physical channel. Because the frequency domain resources used to transmit the physical channel are determined based on the frequency domain position of the target subband, valid frequency domain resources can be determined in the active BWP, matching the target subband with the frequency domain resources, thereby achieving scheduled transmission of the physical channel.

[0239] Based on any of the above embodiments, the solutions of the embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0240] It should be noted that the execution subject in each embodiment of the present disclosure can be a terminal or a network device. In the following embodiments, for the sake of ease of description, the execution subject is introduced as an example of a terminal, which does not constitute a limitation on the actual execution subject.

[0241] Optionally, the frequency domain resource allocation type of the physical channel can be any resource allocation type, such as resource allocation type 0 (Type 0), resource allocation type 1 (Type 1), and so on. In Type 0, frequency domain resources are allocated discontinuously across the entire bandwidth. This resource allocation method helps improve data transmission reliability in the presence of frequency-domain selective fading or interference. In Type 1, frequency domain resources are allocated continuously across the entire bandwidth. This resource allocation method helps simplify signal processing and improve spectrum efficiency.

[0242] Optionally, the frequency domain resource allocation type of the physical channel is Type 1, that is, the frequency domain resources of the physical channel are continuous within the bandwidth.

[0243] Optionally, the physical channel transmitted in the SBFD symbol may include PUSCH and / or PDSCH. When the physical channel is PUSCH, the target subband is the uplink subband in the SBFD symbol; when the physical channel is PDSCH, the target subband is the downlink subband in the SBFD symbol.

[0244] For a physical channel transmitted in an SBFD symbol, the frequency domain resources used to transmit the physical channel may be determined in the activated BWP based on the frequency domain position of the target subband. Optionally, the physical channel transmitted in the SBFD symbol is a physical channel that meets a preset condition, wherein the preset condition includes at least one of the following conditions 1.1 to 1.5:

[0245] Condition 1.1: All M transmission symbols of the physical channel are SBFD symbols, where M is the number of transmission symbols of the physical channel.

[0246] The terminal can determine the transmission symbols of the physical channel, where M represents the number of transmission symbols for the physical channel and 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. If the symbol type of these M transmission symbols is all SBFD symbols, the physical channel can be determined to be a physical channel transmitted in SBFD symbols. If the symbol type of at least one transmission symbol among the M transmission symbols is not SBFD symbols, the physical channel can be determined not to be a physical channel transmitted in SBFD symbols.

[0247] For any of the M transmission symbols, whether the transmission symbol is an SBFD symbol can be determined by determining whether the transmission symbol includes both an uplink subband and a downlink subband in the frequency domain. If the transmission symbol includes both an uplink subband and a downlink subband in the frequency domain, the transmission symbol is an SBFD symbol. If the transmission symbol does not include both an uplink subband and a downlink subband in the frequency domain, the transmission symbol is not an SBFD symbol.

[0248] Condition 1.2: The first transmission symbol among the M transmission symbols is an SBFD symbol.

[0249] The terminal may only determine whether the first transmission symbol of the physical channel belongs to an SBFD symbol. If so, it may be determined that the physical channel is a physical channel transmitted in an SBFD symbol; if not, it may be determined that the physical channel is not a physical channel transmitted in an SBFD symbol.

[0250] Condition 1.3: The last transmission symbol among the M transmission symbols is an SBFD symbol.

[0251] The terminal may only determine whether the last transmitted symbol of the physical channel belongs to an SBFD symbol. If so, it may be determined that the physical channel is a physical channel transmitted in an SBFD symbol; if not, it may be determined that the physical channel is not a physical channel transmitted in an SBFD symbol.

[0252] Condition 1.4: The number of transmission symbols belonging to SBFD symbols in the M transmission symbols is greater than or equal to a preset number.

[0253] The terminal can determine the symbol type of the M transmission symbols of the physical channel, which may be SBFD symbols or non-SBFD symbols. If the number of transmission symbols that are SBFD symbols among the M transmission symbols is greater than or equal to a preset number, the physical channel can be determined to be a physical channel transmitted in SBFD symbols. If the number of transmission symbols that are SBFD symbols among the M transmission symbols is less than a preset number, the physical channel can be determined to be a physical channel not transmitted in SBFD symbols. The preset number is less than or equal to M.

[0254] Condition 1.5: The ratio of the number of transmission symbols that are SBFD symbols in the M transmission symbols to M is greater than or equal to a preset ratio.

[0255] The terminal can determine the symbol type of the M transmission symbols of the physical channel, which may be SBFD symbols or non-SBFD symbols. If the ratio of the number of transmission symbols that are SBFD symbols in the M transmission symbols to M is greater than or equal to a preset ratio, the physical channel can be determined to be a physical channel transmitted in SBFD symbols. If the ratio of the number of transmission symbols that are SBFD symbols in the M transmission symbols to M is less than the preset ratio, the physical channel can be determined to be a physical channel not transmitted in SBFD symbols. The preset ratio is less than or equal to 1.

[0256] In the embodiment of the present disclosure, the transmission symbol of the physical channel does not belong to the SBFD symbol, which may include the case where the transmission symbol is a symbol that is not configured with an uplink subband, or the case where the transmission symbol is configured with an uplink subband but falls back to a non-SBFD symbol due to the inclusion of a synchronization signal block (SS and PBCH Block, SSB).

[0257] The above embodiment describes how to determine whether a physical channel is transmitted in SBFD symbols. For physical channels transmitted in SBFD symbols, the frequency domain resources used to transmit the physical channel can be determined in the active BWP based on the frequency domain location of the target subband. This process is described below with reference to the accompanying figures.

[0258] FIG4 is a flowchart of determining frequency domain resources for transmitting a physical channel according to an embodiment of the present disclosure. As shown in FIG4 , the flowchart includes:

[0259] S41 : Determine a starting RB of the target subband in the activated BWP based on the frequency domain position of the target subband.

[0260] The starting RB of the target subband in the activated BWP refers to the starting frequency domain position of the portion of the target subband in the activated BWP. The frequency domain position of the target subband in the SBFD symbol is fixed, while the starting RB of the target subband in the activated BWP is related to the relative frequency domain position between the activated BWP and the target subband. This discussion only applies to the case where the frequency domain resources of the target subband and the activated BWP overlap. Non-overlapping frequency domain resources are outside the scope of this invention.

[0261] When the starting RB of the target subband is within the activated BWP, the starting RB of the target subband in the activated BWP is the starting RB of the target subband; when the starting RB of the target subband is outside the activated BWP, the starting RB of the target subband in the activated BWP is the starting RB of the activated BWP.

[0262] Specifically, when the starting RB of the target subband is within the activated BWP, the starting RB of the target subband is part of the activated BWP. Therefore, the starting RB of the target subband can be directly used as the starting RB of the target subband in the activated BWP. When the starting RB of the target subband is outside the activated BWP, the starting RB of the target subband is not part of the activated BWP. Therefore, the starting RB of the activated BWP can be used as the starting RB of the target subband in the activated BWP.

[0263] The following describes how to determine the starting RB of the target subband in the activated BWP by taking the physical channel as PUSCH and the target subband as the uplink subband as an example.

[0264] Figure 5 is a schematic diagram of determining the starting RB of the target subband in the activated BWP provided by an embodiment of the present disclosure. As shown in Figure 5, an example is given of how to determine the starting RB of the target subband in the activated BWP when the physical channel is PUSCH and the target subband is an uplink subband.

[0265] FIG5 illustrates the activated BWP and uplink subband in two different situations.

[0266] In case 1, the starting frequency domain position of the uplink subband is within the activated BWP, then the starting frequency domain position of the uplink subband in the activated BWP is the starting frequency domain position of the uplink subband, and the starting RB of the uplink subband in the activated BWP (that is, the RB where the starting frequency domain position of the uplink subband in the activated BWP is located) is the starting RB of the uplink subband (that is, the starting frequency domain position of the uplink subband).

[0267] In case 2, the starting frequency domain position of the uplink subband is outside the activated BWP. Therefore, the starting frequency domain position of the uplink subband in the activated BWP is the starting frequency domain position of the activated BWP, and the starting RB of the uplink subband in the activated BWP (i.e., the RB where the starting frequency domain position of the uplink subband in the activated BWP is located) is the starting RB of the activated BWP (i.e., the RB where the starting frequency domain position of the activated BWP is located). As shown in Figure 5, frequency domain resources within the uplink subband range but not within the activated BWP are not considered.

[0268] S42 , based on the starting RB of the target subband in the activated BWP and the VRB of the physical channel when mapping from VRB to physical resource block (PRB), determine the starting PRB of the frequency domain resources of the physical channel in the activated BWP.

[0269] Optionally, the mapping from VRBs to PRBs is non-interleaved mapping, which is relative to interleaved mapping. Interleaved mapping is a method of mapping VRBs to PRBs in a shuffled manner. Through this mapping method, VRBs that were originally logically continuous or discontinuous are mapped to PRBs dispersed at the physical layer. Non-interleaved mapping is a more direct mapping method. In this non-interleaved mapping method, there is a one-to-one correspondence between VRBs and PRBs, that is, the VRB number is directly mapped to the PRB number.

[0270] After determining the starting RB of the target subband in the activated BWP, the starting PRB of the frequency domain resources of the physical channel in the activated BWP can be determined in combination with the VRB of the physical channel when mapping from VRB to PRB.

[0271] Optionally, the frequency domain resource of the physical channel is in the starting PRB in the activated BWP and satisfies any one of the following 2.1 to 2.3:

[0272] 2.1, d = n + k1;

[0273] 2.2, d = n + k2 - p;

[0274] 2.3, d = n + k3 - qp;

[0275] Wherein, d is the number of the starting PRB of the frequency domain resource of the physical channel in the activated BWP;

[0276] n is the number of the VRB of the physical channel when mapping from VRB to PRB; k1 is the number of the starting RB of the target subband in the activated BWP relative to the starting RB of the activated BWP;

[0277] k2 is the number of the starting RB of the target subband in the activated BWP relative to the starting RB of the carrier; p is the number of the starting RB of the activated BWP relative to the starting RB of the carrier;

[0278] k3 is the number of the starting RB of the target subband in the activated BWP relative to the starting RB of frequency point A (point A); q is the number of the starting RB of the carrier relative to the starting RB of point A.

[0279] Point A is the common reference point of the resource block grid. Point A can be determined according to the parameter offsetToPointA or the parameter absoluteFrequencyPointA, where the parameter offsetToPointA represents the frequency difference between point A and the lowest point in the frequency domain, indicating the relative frequency domain position of point A, and the parameter absoluteFrequencyPointA represents the absolute frequency domain position of point A.

[0280] In item 2.1, the starting RB of the target subband in the activated BWP is numbered with reference to the starting RB position of the activated BWP, and the starting RB of the target subband in the activated BWP is numbered k1 relative to the starting RB of the activated BWP, where k1 also represents the number of RBs included between the starting RB of the activated BWP and the starting RB of the target subband in the activated BWP.

[0281] In item 2.2, the starting RB of the target subband in the activated BWP is numbered with reference to the starting RB position of the carrier, resulting in k2, the number of the starting RB of the target subband in the activated BWP relative to the starting RB of the carrier. k2 also represents the number of RBs between the starting RB of the carrier and the starting RB of the target subband in the activated BWP. The starting RB of the activated BWP is also numbered with reference to the starting RB position of the carrier, resulting in p, the number of the starting RB of the activated BWP relative to the starting RB of the carrier. p also represents the number of RBs between the starting RB of the carrier and the starting RB of the activated BWP.

[0282] In Item 2.3, the starting RB of the target subband in the activated BWP is numbered with reference to the starting RB position of point A. This yields k3, the number of RBs between the starting RB of point A and the starting RB of the target subband in the activated BWP. Furthermore, the starting RB of the carrier is also numbered with reference to the starting RB position of point A. This yields q, the number of RBs between the starting RB of point A and the starting RB of the carrier. The meaning of q is the same as in Item 2.2 and is not repeated here.

[0283] Based on any one of the above 2.1 to 2.3, the number d of the starting PRB of the frequency domain resources of the physical channel in the activated BWP can be determined, which also determines the starting PRB of the frequency domain resources of the physical channel in the activated BWP.

[0284] S43 : Determine the frequency domain resources of the physical channel in the activated BWP based on the starting PRB of the frequency domain resources of the physical channel in the activated BWP.

[0285] After determining the starting PRB of the frequency domain resources of the physical channel in the activated BWP, that is, the starting PRB of the frequency domain resources of the physical channel in the activated BWP can be used as the starting position, and the frequency domain resources of the physical channel are determined in the activated BWP.

[0286] The starting PRB of the physical channel's frequency domain resources in the activated BWP only indicates the starting position of the physical channel's frequency domain resources. The size of the physical channel's frequency domain resources also needs to be combined to determine the physical channel's frequency domain resources. The size of the physical channel's frequency domain resources needs to be determined in combination with higher-layer signaling configuration or DCI indication.

[0287] The physical channel may be a PUSCH, and 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.

[0288] Optionally, in the case where the physical channel is a PUSCH scheduled by DCI format 0_0, the terminal determines the frequency domain resources for transmitting the PUSCH based on the method of the embodiment of the present disclosure, 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 disclosure, and receives the PUSCH sent by the terminal based on the determined frequency domain resources.

[0289] Optionally, the PUSCH meets at least one of the following 3.1 to 3.3:

[0290] 3.1. PUSCH is the PUSCH scheduled by DCI format 0_0 in the common search space CSS;

[0291] 3.2. PUSCH is the PUSCH scheduled by DCI format 0_0 in the user-specific search space USS;

[0292] 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.

[0293] 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 disclosure, 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 disclosure, and receives the PUSCH sent by the terminal based on the determined frequency domain resources.

[0294] The physical channel may be a PDSCH. Optionally, the PDSCH is 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.

[0295] Optionally, when 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 disclosure, 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 disclosure, and receives the PDSCH sent by the network device based on the determined frequency domain resources.

[0296] Optionally, the PDSCH meets at least one of the following 4.1 to 4.3:

[0297] 4.1. PDSCH is the PDSCH scheduled by DCI format 1_0 in CSS;

[0298] 4.2. PDSCH is the PDSCH scheduled by DCI format 1_0 in USS;

[0299] 4.3. The PDSCH is a PDSCH scheduled in DCI format 1_0 in the USS, with the DCI size determined according to DCI format 1_0 in the CSS.

[0300] Optionally, when the physical channel is a PDSCH and at least one of 4.1 to 4.3 above is met, the network device determines the frequency domain resources for transmitting the PDSCH based on the method of the embodiment of the present disclosure, 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 disclosure, and receives the PDSCH sent by the network device based on the determined frequency domain resources.

[0301] Among them, the method for determining the size of the frequency domain resources of the physical channel can refer to the relevant introduction in the above embodiments. For example, for the PUSCH scheduled by DCI format 0_0 in the CSS, the size of the frequency domain resources is equal to the bandwidth of the initial uplink BWP. For example, for the PDSCH scheduled by DCI format 1_0 in the CSS, when the carrier is configured with CORESET 0, the size of the frequency domain resources is equal to the bandwidth of CORESET 0, otherwise the size of the frequency domain resources 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, when the number of DCI sizes that the terminal needs to blindly detect exceeds 3 exclusive DCI sizes and 1 public DCI size), DCI format 0_0 and DCI format 0_1 ​​in the USS will also use the same method as in the CSS to determine the size of the frequency domain resources, and so on.

[0302] Optionally, for PDSCH transmission in SBFD symbols scheduled by DCI format 1_0 in the CSS, the network device may configure the starting RB of the CORESET resources to be within the downlink subband range to avoid the problem of being unable to determine valid PDSCH transmission resources.

[0303] In the above embodiments, the solutions of the present disclosure are introduced in detail. The solutions of the embodiments of the present disclosure are introduced below by taking PUSCH and PDSCH as examples.

[0304] First, referring to FIG6 to FIG8 , an implementation scheme for determining frequency domain resources in the case of PUSCH transmission is described.

[0305] Figure 6 is a schematic diagram 1 of determining the frequency domain resources for transmitting PUSCH provided by an embodiment of the present disclosure. As shown in Figure 6, the frequency domain range of activating the 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 subband (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.

[0306] First, the starting RB of the uplink subband in the activated uplink BWP must be determined. In the example of Figure 6, 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 frequency domain position D in Figure 6.

[0307] The starting RB of the uplink subband in the activated uplink BWP is numbered based on the starting RB of the activated uplink BWP. For example, if the starting RB of the uplink subband in the activated uplink BWP is numbered k1 relative to the starting RB of the activated uplink BWP, as shown in Figure 6 , this indicates that there are 35 RBs between frequency domain positions B and D. For example, if the VRB number of the physical channel is n=3 during VRB-to-PRB mapping, based on Item 2.1 of the above embodiment, the starting PRB number of the frequency domain resource of the PUSCH in the activated uplink BWP is d=n+k1=3+35=38.

[0308] The starting position of the frequency domain resource can be determined based on the number d of the starting PRB of the PUSCH frequency domain resource in the activated uplink BWP. Combined with the size of the PUSCH frequency domain resource, the frequency domain resource used to transmit the PUSCH can be determined, that is, the frequency domain range indicated by FDRA in Figure 6, that is, the frequency domain range between frequency domain position H and frequency domain position F in Figure 6. The number of RBs included between frequency domain position D and frequency domain position H is n, that is, 3 RBs.

[0309] In conjunction with Figure 6, it can be seen that the scheme of the embodiment of the present disclosure, for the transmission of PUSCH, uses the starting RB of the activated uplink BWP 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 activated uplink BWP, 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. This can determine the effective frequency domain resources for transmitting PUSCH in the uplink subband, thereby effectively scheduling the transmission of PUSCH.

[0310] Figure 7 is a second schematic diagram of determining the frequency domain resources for transmitting PUSCH provided by an embodiment of the present disclosure. As shown in Figure 7, the frequency domain range of activating the uplink BWP (i.e., the frequency domain range between frequency domain position B and frequency domain position C in Figure 7) and the frequency domain range of the uplink subband (i.e., the frequency domain range between frequency domain position D and frequency domain position E in Figure 7) are shown in the SBFD symbol.

[0311] First, the starting RB of the uplink subband in the activated uplink BWP must be determined. In the example of Figure 7 , 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 frequency domain position D in Figure 7 .

[0312] The starting RB of the uplink subband in the activated uplink BWP is numbered based on 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, as shown in Figure 7 , this indicates that there are 60 RBs between frequency domain positions G and D. For example, if the starting RB of the activated uplink BWP is numbered p relative to the starting RB of the carrier, as shown in Figure 7 , this indicates that there are 25 RBs between frequency domain positions G and B. For example, if the VRB number of the physical channel is n = 3 during VRB-to-PRB mapping, based on item 2.2 of the above embodiment, the starting PRB number of the PUSCH frequency domain resource in the activated uplink BWP is d = n + k2 - p = 3 + 60 - 25 = 38.

[0313] The starting position of the frequency domain resource can be determined based on the number d of the starting PRB of the PUSCH frequency domain resource in the activated uplink BWP. Combined with the size of the PUSCH frequency domain resource, the frequency domain resource used to transmit the PUSCH can be determined, that is, the frequency domain range indicated by FDRA in Figure 7, that is, the frequency domain range between frequency domain position H and frequency domain position F in Figure 7. The number of RBs included between frequency domain position D and frequency domain position H is n, that is, 3 RBs.

[0314] In conjunction with Figure 7, it can be seen that the scheme of the embodiment of the present disclosure, 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. This can determine the effective frequency domain resources for transmitting PUSCH in the uplink subband, thereby effectively scheduling the transmission of PUSCH.

[0315] Figure 8 is a third schematic diagram of determining the frequency domain resources for transmitting PUSCH provided by an embodiment of the present disclosure. As shown in Figure 8, the frequency domain range of activating the uplink BWP (i.e., the frequency domain range between frequency domain position B and frequency domain position C in Figure 8) and the frequency domain range of the uplink subband (i.e., the frequency domain range between frequency domain position D and frequency domain position E in Figure 8) are shown in the SBFD symbol.

[0316] First, the starting RB of the uplink subband in the activated uplink BWP must be determined. In the example of Figure 8 , 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 frequency domain position D in Figure 8 .

[0317] The starting RB of the uplink subband in the activated uplink BWP is numbered based on the starting RB of point A. For example, if the starting RB of the uplink subband in the activated uplink BWP is numbered 84 relative to the starting RB of point A, as shown in Figure 8 , this indicates that 84 RBs are included between frequency domain position I and frequency domain position D. For example, if the starting RB of the activated uplink BWP is numbered 25 relative to the starting RB of the carrier, as shown in Figure 8 , this indicates that 25 RBs are included between frequency domain position G and frequency domain position B. For example, if the starting RB of the carrier is numbered 24 relative to the starting RB of point A, as shown in Figure 8 , this indicates that 24 RBs are included between frequency domain position I and frequency domain position G.

[0318] Taking the VRB number n=3 of the physical channel when mapping from VRB to PRB as an example, based on item 2.3 in the above embodiment, it can be known that the starting PRB number of the frequency domain resource of PUSCH in the activated uplink BWP is d=n+k3-qp=3+84-24-25=38.

[0319] The starting position of the frequency domain resource can be determined based on the number d of the starting PRB of the PUSCH frequency domain resource in the activated uplink BWP. Combined with the size of the PUSCH frequency domain resource, the frequency domain resource used to transmit the PUSCH can be determined, that is, the frequency domain range indicated by FDRA in Figure 8, that is, the frequency domain range between frequency domain position H and frequency domain position F in Figure 8. The number of RBs included between frequency domain position D and frequency domain position H is n, that is, 3 RBs.

[0320] In conjunction with Figure 8, it can be seen that the scheme of the embodiment of the present disclosure, for the transmission of PUSCH, uses the starting RB of point A 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 point A, 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, so as to determine the effective frequency domain resources for transmitting PUSCH in the uplink subband, thereby effectively scheduling the transmission of PUSCH.

[0321] It should be noted that, in the embodiments of Figures 6 to 8, the starting RB of the uplink subband is in the activated uplink BWP. In other embodiments, the starting RB of the uplink subband is not in the activated uplink BWP. In this case, the starting RB of the uplink subband in the activated uplink BWP can be determined with reference to the solution of the embodiment of Figure 5. The other processes remain unchanged and will not be repeated here.

[0322] In the above embodiment, the implementation scheme of how to determine frequency domain resources in the case of PUSCH transmission is introduced in conjunction with Figures 6 to 8. The implementation scheme of how to determine frequency domain resources in the case of PDSCH transmission is introduced below in conjunction with Figures 9 to 12.

[0323] For SBFD terminals, when the network device schedules the PDSCH transmitted in the SBFD symbol through 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 within the downlink subband range in configuration, 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 subband. Figure 9 is a schematic diagram of the starting RB position of the CORESET provided in an embodiment of the present disclosure. As shown in Figure 9, the SBFD symbol includes an uplink subband and a downlink subband. For case A, the starting RB of the CORESET is within the downlink subband range; for case B, the starting RB of the CORESET is within the uplink subband range.

[0324] Figure 10 is a schematic diagram 1 of determining the frequency domain resources for transmitting PDSCH provided by an embodiment of the present disclosure. As shown in Figure 10, the frequency domain range of activating the downlink BWP (i.e., the frequency domain range between frequency domain position J and frequency domain position K in Figure 10) and the frequency domain range of the downlink subband (i.e., the frequency domain range between frequency domain position L and frequency domain position K in Figure 10) are shown in the SBFD symbol.

[0325] First, determine the starting RB of the downlink subband within the activated downlink BWP. In the example of Figure 10, the starting RB of the downlink subband is within the activated downlink BWP. Therefore, the starting RB of the downlink subband within the activated downlink BWP is the starting RB of the downlink subband, and the corresponding frequency domain position is frequency domain position L in Figure 10.

[0326] The starting RB of a downlink subband in an activated downlink BWP is numbered based on the starting RB of the activated downlink BWP. For example, if the starting RB of the downlink subband in an activated downlink BWP is numbered k1 relative to the starting RB of the activated downlink BWP, as shown in Figure 10 , this indicates that there are 30 RBs between frequency domain position J and frequency domain position L. For example, if the VRB number n = 15 of the physical channel is used for VRB-to-PRB mapping, based on Item 2.1 of the above embodiment, the starting PRB number of the frequency domain resource of the PDSCH in the activated downlink BWP is d = n + k1 = 15 + 30 = 45.

[0327] 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 frequency domain resource of the SCH under P, the frequency domain resource used to transmit the PDSCH can be determined, that is, the frequency domain range indicated by FDRA in Figure 10, that is, the frequency domain range between frequency domain position N and frequency domain position O in Figure 10. Among them, the number of RBs included between frequency domain position L and frequency domain position N is n, that is, 15 RBs.

[0328] In conjunction with Figure 10, it can be seen that the scheme of the embodiment of the present disclosure, for the transmission of PDSCH, uses the starting RB of the activated downlink BWP 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 activated downlink BWP, 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, which can determine the effective frequency domain resources for transmitting PDSCH in the downlink subband, thereby effectively scheduling the transmission of PDSCH.

[0329] Figure 11 is a second schematic diagram of determining the frequency domain resources for transmitting PDSCH provided by an embodiment of the present disclosure. As shown in Figure 11, the frequency domain range of activating the downlink BWP (i.e., the frequency domain range between frequency domain position J and frequency domain position K in Figure 11) and the frequency domain range of the downlink subband (i.e., the frequency domain range between frequency domain position L and frequency domain position K in Figure 11) are shown in the SBFD symbol.

[0330] First, determine the starting RB of the downlink subband within the activated downlink BWP. In the example of Figure 11, the starting RB of the downlink subband is within the activated downlink BWP. Therefore, the starting RB of the downlink subband within the activated downlink BWP is the starting RB of the downlink subband, and the corresponding frequency domain position is frequency domain position L in Figure 11.

[0331] The starting RB of the downlink subband in the activated downlink BWP is numbered based on the starting RB of the carrier. For example, if the starting RB of the downlink subband in the activated downlink BWP is numbered k2 relative to the starting RB of the carrier, as shown in Figure 11, 40 RBs are included between frequency domain positions P and L. For example, if the starting RB of the activated downlink BWP is numbered p relative to the starting RB of the carrier, as shown in Figure 11, 10 RBs are included between frequency domain positions P and J. For example, if the VRB number n = 15 of the physical channel during VRB-to-PRB mapping is 15, based on item 2.2 of the above embodiment, the starting PRB number of the frequency domain resource of the PDSCH in the activated downlink BWP is d = n + k2 - p = 15 + 40 - 10 = 45.

[0332] 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, the frequency domain range indicated by FDRA in Figure 11, that is, the frequency domain range between frequency domain position N and frequency domain position O in Figure 11. The number of RBs included between frequency domain position L and frequency domain position N is n, that is, 15 RBs.

[0333] In conjunction with Figure 11, it can be seen that the scheme of the embodiment of the present disclosure, 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.

[0334] Figure 12 is a third schematic diagram of determining the frequency domain resources for transmitting PDSCH provided by an embodiment of the present disclosure. As shown in Figure 12, the frequency domain range of activating the downlink BWP (i.e., the frequency domain range between frequency domain position J and frequency domain position K in Figure 12) and the frequency domain range of the downlink subband (i.e., the frequency domain range between frequency domain position L and frequency domain position K in Figure 12) are shown in the SBFD symbol.

[0335] First, determine the starting RB of the downlink subband within the activated downlink BWP. In the example of Figure 12, the starting RB of the downlink subband is within the activated downlink BWP. Therefore, the starting RB of the downlink subband within the activated downlink BWP is the starting RB of the downlink subband, and the corresponding frequency domain position is frequency domain position L in Figure 12.

[0336] The starting RB of the downlink subband in the activated downlink BWP is numbered based on the starting RB of point A. For example, if the starting RB of the downlink subband in the activated downlink BWP is numbered k3 50 relative to the starting RB of point A, as shown in Figure 12, this indicates that 50 RBs are included between frequency domain positions Q and L. For example, if the starting RB of the activated downlink BWP is numbered p 10 relative to the starting RB of the carrier, as shown in Figure 12, this indicates that 10 RBs are included between frequency domain positions P and J. For example, if the starting RB of the carrier is numbered q 10 relative to the starting RB of point A, as shown in Figure 12, this indicates that 10 RBs are included between frequency domain positions Q and P.

[0337] Taking the VRB number n=15 of the physical channel when mapping from VRB to PRB as an example, based on item 2.3 in the above embodiment, it can be seen that the starting PRB number of the frequency domain resource of PUSCH in the activated downlink BWP is d=n+k3-qp=15+50-10-10=45.

[0338] 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, the frequency domain range indicated by FDRA in Figure 12, that is, the frequency domain range between frequency domain position N and frequency domain position O in Figure 12. Among them, the number of RBs included between frequency domain position L and frequency domain position N is n, that is, 15 RBs.

[0339] In conjunction with Figure 12, it can be seen that the scheme of the embodiment of the present disclosure, for the transmission of PDSCH, uses the starting RB of point A 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 point A, 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, so as to determine the effective frequency domain resources for transmitting PDSCH in the downlink subband, thereby effectively scheduling the transmission of PDSCH.

[0340] It should be noted that, in the embodiments of Figures 10 to 12, the starting RB of the downlink subband is in the activated downlink BWP. In other embodiments, the starting RB of the downlink subband is not in the activated downlink BWP. In this case, the starting RB of the downlink subband in the activated downlink BWP can be determined with reference to the solution of the embodiment of Figure 5. The other processes remain unchanged and will not be repeated here.

[0341] It should be noted that in the embodiments of Figures 10 to 12, the example of the case where only one downlink subband is included in the SBFD symbol is used for description, namely, SBFD subband configuration 2 in Figure 1, namely, the {DU} mode. However, the solution of the embodiment of the present disclosure can be applied to the case where only one downlink subband is included in the SBFD symbol (i.e., the {DU} mode), and can also be applied to the case where the SBFD symbol includes two downlink subbands (i.e., the {DUD} mode). In the case where the SBFD symbol includes two downlink subbands, the frequency domain resources for transmitting the PDSCH can be determined based on the frequency domain position of any one of the two downlink subbands, or the frequency domain resources for transmitting the PDSCH can be determined based on the frequency domain position of the downlink subband with the lower frequency domain position among the two downlink subbands. The embodiment of the present disclosure is not limited to this.
