Description

Method and device for determining resource block combination, terminal equipment, and network equipment Technical Field

[0001] The embodiments of the present application relate to the field of mobile communication technology, and specifically to a method and apparatus for determining a resource block combination, a terminal device, and a network device. Background Art

[0002] The resource block combination size indicates the number of physical resource blocks (PRBs) contained in a resource block combination. Currently, the resource block combination size is determined at least according to the size of the bandwidth part (BWP), and the BWP size is the BWP size. However, for the subband non-overlapping full duplex (SBFD) system, the frequency domain resources for downlink transmission are not the entire BWP, but part of the frequency domain resources of the BWP. Therefore, the current method for determining the resource block combination size is not applicable to the SBFD system. If the current method for determining the resource block combination size is adopted, the determined resource block combination size will be larger, and a larger resource block combination will lead to a decrease in system efficiency.

[0064] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0065] 1. Uplink subband of downlink symbol / time slot

[0066] SBFD is also known as X-Division Duplex (XDD). SBFD is a new duplex standard that achieves full-duplex operation by dividing non-overlapping uplink sub-bands and downlink sub-bands within a time division duplex (TDD) carrier, and performing uplink transmission and downlink transmission on the uplink sub-band and downlink sub-band respectively. In SBFD, since the frequency domain resources corresponding to the same time domain unit include uplink sub-bands and downlink sub-bands, it is possible to simultaneously perform downlink transmission and uplink transmission on different sub-bands of the same time domain unit. SBFD is mainly used on the network equipment side. Specifically, the network equipment can simultaneously perform downlink transmission and uplink reception on different sub-bands of the same time domain unit; the terminal equipment side still uses TDD, that is, only downlink reception or uplink transmission is supported within the same time domain unit.

[0067] For example, as shown in Figure 2, in TDD, all frequency domain resources corresponding to downlink symbols / time slots are used for downlink transmission. In SBFD, however, the frequency domain resources corresponding to downlink symbols / time slots are divided into non-overlapping uplink subbands and downlink subbands, where the uplink subbands are used for uplink transmission and the downlink subbands are used for downlink transmission. The downlink transmission here can be the transmission of the Physical Downlink Shared Channel (PDSCH).

[0068] 2. Resource Block Combination

[0069] A resource block combination consists of several PRBs. There are many types of resource block combinations. The following describes the meanings of several resource block combinations and how to determine the corresponding resource block combination sizes.

[0070] 1) Resource Block Group (RBG)

[0071] RBG is a basic scheduling unit for frequency domain resource allocation of data channels, that is, network equipment allocates frequency domain resources of data channels with RBG as the granularity. The data channel is, for example, PDSCH, Physical Uplink Shared Channel (PUSCH).

[0072] The RBG size indicates the number of PRBs contained in an RBG. The RBG size is related to the BWP size and configuration. The configuration here refers to the configuration configured through the high-level parameter rbg-size. rbg-size has two configurations: {config1, config2}. config1 represents Configuration 1, and config2 represents Configuration 2.

[0073] For PDSCH, the configuration path of rbg-size is: downlink dedicated BWP configuration (BWP-DownlinkDedicated) → PDSCH configuration (PDSCH-Config) → rbg-Size configuration, which can be recorded as BWP-DownlinkDedicated{PDSCH-Config{rbg-Size}}.

[0074] For PUSCH, the configuration path of rbg-size is: uplink dedicated BWP configuration (BWP-UplinkDedicated) → PUSCH configuration (PUSCH-Config) → rbg-Size configuration, which can be recorded as BWP-UplinkDedicated{PUSCH-Config{rbg-Size}}.

[0075] For the PUSCH with configuration grant, the configuration path of rbg-size is: uplink dedicated BWP configuration (BWP-UplinkDedicated) → configuration grant configuration (ConfiguredGrantConfig) → rbg-size configuration, which can be recorded as BWP-UplinkDedicated{ConfiguredGrantConfig{rbg-Size}}.

[0076] The relationship between RBG size, BWP size and configuration can be seen in Table 1 below.

[0077] Table 1

[0078] 2) Precoding Resource Block Group (PRG)

[0079] PRG refers to a PRB combination using the same precoding, and these PRB combinations with the same precoding are used for PDSCH transmission.

[0080] The PRG size (PRG Size) indicates the number of PRBs contained in a PRG. The determination of the PRG size is related to a) the UE capability of the terminal device, b) the RRC configuration, and c) the number of consecutive PRBs scheduled by the network device for the terminal device. Among them, the UE capability is implemented through the downlink dynamic PRB bundling (dynamicPRB-BundlingDL) parameter, which is used to indicate whether the terminal device supports the PRG size for indicating PDSCH reception based on downlink control information (DCI). If the network device receives the dynamicPRB-BundlingDL reported by the terminal device, it indicates that the terminal device supports the PRG size for indicating PDSCH reception based on DCI. The RRC configuration is implemented through the PRB bundling type (prb-BundlingType) parameter, which is used to implement RRC configuration of the PRG size. The number of consecutive PRBs scheduled by the network device for the terminal device will be compared with (BWP size) / 2.

[0081] There are three PRG size configurations: {2, 4, wideband}. The specific configuration strategies are as follows:

[0082] For PDSCH scheduled by DCI format 1_0, the PRG size is fixedly configured to 2.

[0083] For PDSCH scheduled with DCI format 1_1, the PRG size is configured as follows:

[0084] A) If the terminal device does not have the dynamic PRB-Bundling DL capability, the network device can only use RRC to statically configure the PRG size. In this case, the prb-BundlingType is static bundling.

[0085] If bundleSize=4 is configured, then PRG size=4;

[0086] If bundleSize=wideband is configured, then PRG size=wideband.

[0087] Among them, bundleSize is a configuration parameter under staticBundling.

[0088] B) If the terminal device has dynamic PRB-Bundling DL capability, the network device can use 1) RRC+DCI to dynamically configure the PRG size, or 2) RRC to statically configure the PRG size.

[0089] 1)RRC+DCI dynamically configures PRG size:

[0090] In the RRC configuration, prb-BundlingType is dynamic binding (dynamicBundling), and bundleSizeSet1 and bundleSizeSet2 can be configured under dynamicBundling.

[0091] In the DCI indication, the field PRB bundling size indicator uses one bit to indicate bundleSizeSet1 or bundleSizeSet2. A bit value of 1 indicates that bundleSizeSet1 is used, and a bit value of 0 indicates that bundleSizeSet2 is used.

[0092] Among them, bundleSizeSet1={n4,wideband,n2-wideband,n4-wideband}; bundleSizeSet2={n4,wideband}.

[0093] 1-1) If the PRB bundling size indicator field in the DCI indicates bundleSizeSet1, then:

[0094] If RRC configuration bundleSizeSet1 = 4, then PRG size = n4;

[0095] If RRC configuration bundleSizeSet1 = wideband, then PRG size = wideband;

[0096] If RRC configures bundleSizeSet1 = n2-wideband, then: if the number of consecutive PRBs scheduled by the network device for the terminal device is greater than (BWP size) / 2, then PRG size = wideband; otherwise, PRG size = 2;

[0097] If RRC configures bundleSizeSet1=n4-wideband, then: if the number of consecutive PRBs scheduled by the terminal device is greater than (BWP size) / 2, then PRG size=wideband; otherwise, PRG size=4.

[0098] 1-2) If the PRB bundling size indicator field in the DCI indicates bundleSizeSet2, then:

[0099] If RRC configuration bundleSizeSet2 = 4, then PRG size = 4;

[0100] If RRC configuration bundleSizeSet2=wideband, then PRG size=wideband.

[0101] 2)RRC static configuration PRG size:

[0102] In the RRC configuration, prb-BundlingType is static binding (staticBundling).

[0103] If bundleSize=4 is configured, then PRG size=4;

[0104] If bundleSize=wideband is configured, then PRG size=wideband.

[0105] Among them, bundleSize is a configuration parameter under staticBundling.

[0106] C) If a network device does not configure bundleSize(Set) through RRC, the default PRG size=2.

[0107] It should be noted that when the PRG size is configured as wideband, it means that the PRG size is equal to the number of consecutive PRBs scheduled by the network device for the terminal device. The frequency domain resources allocated to the terminal device must be consecutive PRBs, and the same precoding is used on these consecutive PRBs.

[0108] 3) Subband Size

[0109] Subband size indicates the number of PRBs contained in a subband. Subband size is the granularity of channel state information (CSI) reporting, that is, subband size PRBs are reported as a whole as a CSI information. Subband size is related to BWP size and configuration. The configuration here refers to the configuration performed through the high-level parameter subbandSize. SubbandSize has two configurations {value1, value2}, where value1 represents value 1 and value2 represents value 2. The configuration path of subbandSize is: serving cell configuration (ServingCellConfig) → CSI measurement configuration (CSI-MeasConfig) → CSI reporting configuration (CSI-ReportConfig) → subbandSize configuration, which can be recorded as ServingCellConfig{CSI-MeasConfig{CSI-ReportConfig{subbandSize}}}.

[0110] The relationship between the subband size, BWP size, and configuration can be referred to in the following Table 2, where the subband size has two values, corresponding to value 1 and value 2 respectively. Generally, the first of the two values ​​is value 1 (i.e., value 1), and the second value is value 2 (i.e., value 2).

[0111] Table 2

[0112] According to the aforementioned related technologies, the RBG size / subband size is determined at least based on the BWP size. However, for SBFD systems, the frequency domain resource for downlink transmission is not the entire BWP, but rather the downlink subband portion of the BWP. This means that the frequency domain resource size for downlink transmission is smaller than the BWP size. Therefore, the current method for determining the RBG size / subband size is not suitable for SBFD systems. This will result in an excessively large RBG size / subband size, leading to coarse resource allocation / coarse precoding and reduced system efficiency. Furthermore, while the PRG size can be flexibly and independently configured, it is closely related to the RBG size / subband size. As the RBG size / subband size increases, the PRG size also increases. This increase in PRG size leads to coarse shaping and reduced transmission efficiency.

[0113] To this end, the following technical solutions are proposed in the embodiments of the present application: The technical solutions in the embodiments of the present application can improve the system efficiency of SBFD by enhancing the method for determining the size of resource block combinations.

[0114] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0115] It should be noted that in the embodiment of the present application, the time domain unit in SBFD is referred to as an SBFD time domain unit (that is, the first type of time domain unit), including SBFD symbols, SBFD sub-time slots, SBFD time slots or SBFD subframes. In some cases, the SBFD time domain unit can also be described as a downlink time domain unit, such as a downlink symbol, a downlink sub-time slot, a downlink time slot or a downlink subframe, but it should be clear that the frequency domain resources corresponding to the downlink time domain unit are divided into uplink subbands and downlink subbands. Among them, the number of uplink subbands can be one or more, and the number of downlink subbands can be one or more. In addition, the distribution of uplink subbands and downlink subbands in the frequency domain can have multiple ways. As an implementation method: an uplink subband is located in the middle of two downlink subbands.

[0116] It should be noted that, in the embodiment of the present application, the at least two frequency domain resources within the first bandwidth may be non-contiguous frequency domain resources. The technical solution of the embodiment of the present application may also be adopted for at least two continuous frequency domain resources.

[0117] It should be noted that, in the embodiment of the present application, the time domain unit in TDD is referred to as a non-SBFD time domain unit (i.e., a second type of time domain unit), such as a TDD symbol, a TDD sub-time slot, a TDD time slot, or a TDD subframe. The time domain unit in TDD can be a downlink time domain unit, such as a downlink symbol, a downlink sub-time slot, a downlink time slot, or a downlink subframe, and the frequency domain resources corresponding to the downlink time domain unit all belong to downlink resources. The time domain unit in TDD can also be an uplink time domain unit, such as an uplink symbol, an uplink sub-time slot, an uplink time slot, or an uplink subframe, and the frequency domain resources corresponding to the uplink time domain unit all belong to uplink resources.

[0118] It should be noted that in the embodiments of the present application, the resource block size may refer to the RBG size, the PRG size, or the subband size. The definitions of the RBG size, the PRG size, and the subband size can refer to the description of the aforementioned related art.

[0119] FIG3 is a flowchart of a method for determining a resource block combination according to an embodiment of the present application. As shown in FIG3 , the method includes some or all of the following:

[0120] Step 301: The terminal device determines a resource block combination size corresponding to a first type of time domain unit based on at least two frequency domain resources within a first bandwidth, where the first type of time domain unit is an SBFD time domain unit.

[0121] In some implementations, resource blocks are grouped into RBGs. Accordingly, the size of the resource block group is the RBG size. The definitions of RBGs and RBG sizes can refer to the aforementioned related technologies. Specifically, an RBG is the basic scheduling unit for frequency-domain resource allocation for data channels (e.g., PDSCH and PUSCH). That is, a network device allocates frequency-domain resources for data channels at the RBG granularity. The RBG size indicates the number of PRBs contained in an RBG.

[0122] In other embodiments, resource blocks are combined into subbands. Accordingly, the resource block combination size is the subband size. The relevant definition of the subband size can refer to the aforementioned related technologies. Specifically, the subband size represents the number of PRBs contained in a subband, and the subband size is the granularity of the CSI report.

[0123] In some embodiments, the at least two frequency domain resources may be at least two downlink resources, and the at least two downlink resources are used for downlink transmission. In addition to the at least two downlink resources, the first bandwidth also includes one or more uplink resources, and the one or more uplink resources are used for uplink transmission. It is understood that the first bandwidth includes both downlink resources and uplink resources, wherein downlink resources can also be described as downlink subbands, and uplink resources can also be described as uplink subbands. The uplink subbands and downlink subbands can be distributed in various ways within the first bandwidth, for example, an uplink subband is located between two downlink subbands.

[0124] For the first type of time domain unit (ie, SBFD time domain unit), the corresponding first bandwidth includes both downlink resources and uplink resources. For downlink transmission, the corresponding resource block combination size is determined based on at least two downlink resources within the first bandwidth.

[0125] In other embodiments, the at least two frequency domain resources may be at least two uplink resources, which are used for uplink transmission. In addition to the at least two uplink resources, the first bandwidth may also include one or more downlink resources, which are used for downlink transmission. The downlink subbands and uplink subbands may be distributed in various ways within the first bandwidth, for example, a downlink subband may be located between two uplink subbands.

[0126] For the first type of time domain unit (ie, SBFD time domain unit), the corresponding first bandwidth includes both uplink resources and downlink resources. For uplink transmission, the corresponding resource block combination size is determined based on at least two uplink resources within the first bandwidth.

[0127] For RBGs, 1) an RBG is the basic scheduling unit for frequency-domain resource allocation for the PDSCH, i.e., for downlink transmission. Accordingly, the RBG size is determined based on at least two downlink resources within the first bandwidth. 2) an RBG is the basic scheduling unit for frequency-domain resource allocation for the PUSCH, i.e., for uplink transmission. Accordingly, the RBG size is determined based on at least two uplink resources within the first bandwidth.

[0128] For the subband size, the subband size is the granularity of the CSI report, which refers to how many PRBs (ie, the number of PRBs included in the subband size) are used as a whole to report a CSI information. The subband size is determined based on at least two downlink resources within the first bandwidth.

[0129] In some implementations, the first bandwidth may be BWP.

[0130] In an embodiment of the present application, the terminal device determines the resource block combination size corresponding to the first type of time domain unit based on the first parameter and the frequency domain resource size of at least two frequency domain resources within the first bandwidth. The first parameter is used to indicate one of at least two configurations, and each of the at least two configurations is used to determine the resource block combination size corresponding to different frequency domain resource sizes.

[0131] The following describes how to determine the RBG size and the subband size, respectively, by combining resource blocks into RBGs and subbands.

[0132] 1) Resource blocks are grouped into RBGs. The meaning of RBGs can be found in the aforementioned related description. The RBG size (RBG Size) is related to the frequency domain resource size of at least two frequency domain resources and a first parameter. The first parameter here can be the high-level parameter rbg-size. rbg-size has two configurations {config1, config2}, where config1 represents Configuration 1 and config2 represents Configuration 2. The configuration path of rbg-size can be found in the aforementioned related art description.

[0133] For example, the relationship between the RBG size, the frequency domain resource size of at least two frequency domain resources, and the configuration indicated by the first parameter can be referenced in Table 3 below. Based on the relationship shown in Table 3, the corresponding RBG size can be determined based on the frequency domain resource size of the at least two frequency domain resources and the configuration indicated by the first parameter. For example, if the frequency domain resource size of the at least two frequency domain resources is 72 and the configuration indicated by the first parameter is 1, based on the relationship shown in Table 3, the RBG size can be determined to be 4.

[0134] Table 3

[0135] 2) Resource blocks are grouped into subbands. The meaning of subbands can be found in the aforementioned related description. The subband size (Subband Size) is related to the frequency domain resource size of at least two frequency domain resources and a first parameter. The first parameter here can be the high-level parameter subbandSize. SubbandSize has two configurations: {value1, value2}, where value1 represents value 1 and value2 represents value 2. The configuration path of subbandSize can be found in the aforementioned related art description.

[0136] For example, the relationship between the subband size, the frequency domain resource size of at least two frequency domain resources, and the configuration indicated by the first parameter can be referred to in the following Table 4, where the subband size has two values, corresponding to value 1 and value 2, respectively, and the first value of the two values ​​is value 1, and the second value is value 2. According to the relationship shown in Table 4, the corresponding subband size can be determined according to the frequency domain resource size of the at least two frequency domain resources and the configuration indicated by the first parameter.

[0137] Table 4

[0138] In some embodiments, the determination of the resource block combination size is also related to the first frequency domain resource indication field size, that is, the terminal device determines the resource block combination size corresponding to the first type of time domain unit based on the first parameter, the first frequency domain resource indication field size, and the frequency domain resource sizes of at least two frequency domain resources within the first bandwidth. It should be noted that the frequency domain resource indication field size refers to the number of bits occupied by the frequency domain resource indication field.

[0139] Here, the size of the first frequency-domain resource indication field is determined based on the frequency-domain resource size of the first bandwidth and the first parameter. Specifically, based on the frequency-domain resource size of the first bandwidth and the configuration indicated by the first parameter, in combination with Table 1 or Table 2 above, a resource block combination size, referred to as a reference resource block combination size, can be determined. By dividing the resource block combination on the first bandwidth based on the reference resource block combination size, M (M is a positive integer) resource block combinations can be obtained. Therefore, the size of the first frequency-domain resource indication field is M. The first frequency-domain resource indication field is used to indicate scheduled resource block combinations and / or unscheduled resource block combinations among the M resource block combinations. Specifically, each bit in the first frequency-domain resource indication field corresponds to a resource block combination, and the value of the bit is used to indicate whether the corresponding resource block combination is scheduled. For example, a bit value of 1 (or 0) indicates that the corresponding resource block combination is scheduled, and a bit value of 0 (or 1) indicates that the corresponding resource block combination is not scheduled.

[0140] Considering that the frequency domain resource indication field is carried in the DCI, and the terminal device expects the size of the DCI to be fixed or not change much, otherwise the terminal device's blind detection complexity for the DCI will increase. Therefore, the frequency domain resource indication field size determined according to the resource block combination size corresponding to the first type of time domain unit needs to be less than or equal to the above-mentioned first frequency domain resource indication field size. This places a limit on the determination of the resource block combination size corresponding to the first type of time domain unit. The following are two ways to determine the resource block combination size corresponding to the first type of time domain unit:

[0141] Method 1: The resource block combination size corresponding to the first type of time domain unit is the resource block combination size that meets the first condition in the resource block combination size set, and the first condition is: the frequency domain resource indication domain size determined according to the resource block combination size is less than or equal to the first frequency domain resource indication domain size.

[0142] Exemplarily, the resource block combination size set may be a set of RBG sizes {2, 4, 8, 16} as shown in Table 3, or may be a set of subband sizes {4, 8, 16, 32} as shown in Table 4.

[0143] Here, the method for determining the corresponding frequency domain resource indication field size based on the resource block combination size is similar to the method for determining the first frequency domain resource indication field size described above. Specifically, by dividing the resource block combination on the first bandwidth based on the resource block combination size, N1 (N1 is a positive integer) resource block combinations can be obtained. In this case, the frequency domain resource indication field size is N1. The first condition can be understood as: the frequency domain resource indication field size N1 determined based on the resource block combination size is less than or equal to the first frequency domain resource indication field size M.

[0144] Furthermore, if there are multiple resource block combination sizes that meet the first condition in the resource block combination size set, the resource block combination size corresponding to the first type of time domain unit is the minimum resource block combination size that meets the first condition.

[0145] Method 2: If the frequency domain resource indication domain size determined according to the first resource block combination size is less than or equal to the first frequency domain resource indication domain size, then the resource block combination size corresponding to the first type of time domain unit is the first resource block combination size, and the first resource block combination size is determined according to the frequency domain resource size of at least two frequency domain resources and the first parameter; if the frequency domain resource indication domain size determined according to the first resource block combination size is greater than the first frequency domain resource indication domain size, then the resource block combination size corresponding to the first type of time domain unit is the second resource block combination size, and the second resource block combination size is determined according to the frequency domain resource size of the first bandwidth and the first parameter.

[0146] Here, the method of determining the size of the frequency domain resource indication field according to the size of the first resource block combination is similar to the method of determining the size of the first frequency domain resource indication field mentioned above. Specifically, the resource block combination is divided on the first bandwidth according to the size of the first resource block combination, and N2 (N2 is a positive integer) resource block combinations can be obtained. Then, the size of the frequency domain resource indication field is N2.

[0147] Method 2 can also be understood as, if the frequency domain resource indication domain size determined according to the first resource block combination size is less than or equal to the first frequency domain resource indication domain size, then the resource block combination size corresponding to the first type of time domain unit is determined according to the frequency domain resource size and the first parameter of at least two frequency domain resources; if the frequency domain resource indication domain size determined according to the first resource block combination size is greater than the first frequency domain resource indication domain size, then the resource block combination size corresponding to the first type of time domain unit is determined according to the frequency domain resource size and the first parameter of the first bandwidth.

[0148] Exemplarily, according to the relationship shown in Table 3 or Table 4 above, the corresponding resource block combination size can be determined according to the frequency domain resource sizes of at least two frequency domain resources and the configuration indicated by the first parameter.

[0149] Exemplarily, according to the relationship shown in Table 1 or Table 2 above, the corresponding resource block combination size can be determined according to the frequency domain resource size of the first bandwidth and the configuration indicated by the first parameter.

[0150] In the embodiment of the present application, the terminal device determines the size of each resource block combination in the first bandwidth based on the resource block combination size corresponding to the first type of time domain unit. In other words, the terminal device divides the resource block combination within the first bandwidth based on the resource block combination size corresponding to the first type of time domain unit.

[0151] In some implementations, the terminal device determines the size of each resource block combination in the first bandwidth based on the first number, the resource block combination size corresponding to the first type of time domain unit, and the frequency domain resource sizes of at least two frequency domain resources; the first number is the number corresponding to the first PRB in the first bandwidth.

[0152] 1) The size of the first resource block combination in the first bandwidth is determined as follows:

[0153] The size of the first resource block combination in the first bandwidth is determined according to the first number and the size of the resource block combination corresponding to the first type of time domain unit.

[0154] Exemplarily, the resource block combination size corresponding to the first type of time domain unit is P, and the terminal device divides the resource block combination within the first bandwidth according to P, where the size of the divided resource block combination is recorded as P′. The size P′ of the first resource block combination in the first bandwidth is determined based on the following formula:

[0155] in, Represents the number corresponding to the first PRB in the first bandwidth, and mod is the modulo operation.

[0156] 2) The size of the last resource block combination in the first bandwidth is determined as follows:

[0157] If the first value is not equal to 0, the size of the last resource block combination of the first bandwidth is equal to the first value; or, if the first value is equal to 0, the size of the last resource block combination in the first bandwidth is equal to the resource block combination size corresponding to the first type of time domain unit; the first value is determined based on the first number, the resource block combination size corresponding to the first type of time domain unit and the frequency domain resource size of the first bandwidth.

[0158] Exemplarily, the resource block combination size corresponding to the first type of time domain unit is P, and the terminal device divides the resource block combination within the first bandwidth according to P, where the size of the divided resource block combination is recorded as P'. The size P' of the last resource block combination in the first bandwidth is determined based on the following formula:

[0159] if but

[0160] Otherwise, P′=P; (2)

[0161] in, Represents the number corresponding to the first PRB in the first bandwidth, Represents the frequency domain resource size of the first bandwidth, that is, the number of PRBs included in the first bandwidth.

[0162] 3) The size of the middle resource block combination in the first bandwidth is determined as follows:

[0163] The size of the middle resource block combination in the first bandwidth is equal to the size of the resource block combination corresponding to the first type of time domain unit.

[0164] For example, the resource block combination size corresponding to the first type of time domain unit is P, and the terminal device divides the resource block combination within the first bandwidth according to P, wherein the size of the divided resource block combination is recorded as P′, and the size P′ of the intermediate resource block combination in the first bandwidth is determined based on the following formula: P′=P (3)

[0165] After the size of each resource block combination in the first bandwidth is determined through the above solution, the resource block combination can be divided within the first bandwidth based on the size.

[0166] In some embodiments, if there is a first resource block combination in the first bandwidth in which some PRBs do not belong to the above-mentioned frequency domain resources (which can be any one of the above-mentioned at least two frequency domain resources), then the first resource block combination is adjusted to include only some PRBs belonging to the above-mentioned frequency domain resources.

[0167] Here, the first resource block combination may be the first resource block combination of frequency domain resources, or the last resource block combination of frequency domain resources.

[0168] Exemplarily, the at least two frequency domain resources in the first bandwidth include a first downlink subband and a second downlink subband, and there is an uplink subband between the first downlink subband and the second downlink subband. After dividing the resource block combination within the first bandwidth, N resource block combinations can be obtained. Case 1) For the last resource block combination of the first downlink subband, if there are some PRBs in the resource block combination that do not belong to the first downlink subband, then the resource block combination is adjusted to include only the part of PRBs that belong to the first downlink subband. Case 2) For the first resource block combination of the second downlink subband, if there are some PRBs in the resource block combination that do not belong to the second downlink subband, then the resource block combination is adjusted to include only the part of PRBs that belong to the second downlink subband.

[0169] In some implementations, after dividing the resource block combinations within the first bandwidth, N resource block combinations may be obtained, and K of the N resource block combinations fall within the frequency domain resources (the frequency domain resources may refer to any one of the at least two frequency domain resources). Among the K resource block combinations, there may be one or more resource block combinations (referred to as first resource block combinations) in which some PRBs do not belong to the frequency domain resources. In this case, the first resource block combination only includes PRBs belonging to the frequency domain resources.

[0170] In the above-mentioned technical solution of the embodiment of the present application, for the first type of time domain unit (i.e., SBFD time domain unit), the corresponding resource block combination size is no longer determined based on the first bandwidth, but is determined based on at least two frequency domain resources within the first bandwidth. In this way, the method for determining the resource block combination size is enhanced, and the resource block combination size determined in this way is more accurate for the first type of time domain unit (i.e., SBFD time domain unit).

[0171] FIG4 is a second flow chart of a method for determining a resource block combination provided in an embodiment of the present application. As shown in FIG4 , the method includes some or all of the following contents:

[0172] Step 401: The network device performs downlink transmission on the first type of time domain unit, and the terminal device receives the downlink transmission on the first type of time domain unit. The resource block combination size corresponding to the first type of time domain unit is determined based on at least two frequency domain resources within the first bandwidth. The first type of time domain unit is an SBFD time domain unit.

[0173] In some implementations, resource blocks are grouped into RBGs. Accordingly, the size of the resource block group is the RBG size. The definitions of RBGs and RBG sizes can refer to the aforementioned related technologies. Specifically, an RBG is the basic scheduling unit for frequency-domain resource allocation for data channels (e.g., PDSCHs). That is, a network device allocates frequency-domain resources for data channels at the RBG granularity. The RBG size indicates the number of PRBs contained in an RBG.

[0174] In other embodiments, resource blocks are combined into subbands. Accordingly, the resource block combination size is the subband size. The relevant definition of the subband size can refer to the aforementioned related technologies. Specifically, the subband size represents the number of PRBs contained in a subband, and the subband size is the granularity of the CSI report.

[0175] In some embodiments, the at least two frequency domain resources may be at least two downlink resources, and the at least two downlink resources are used for downlink transmission. In addition to the at least two downlink resources, the first bandwidth also includes one or more uplink resources, and the one or more uplink resources are used for uplink transmission. It is understood that the first bandwidth includes both downlink resources and uplink resources, wherein downlink resources can also be described as downlink subbands, and uplink resources can also be described as uplink subbands. The uplink subbands and downlink subbands can be distributed in various ways within the first bandwidth, for example, an uplink subband is located between two downlink subbands.

[0176] For the first type of time domain unit (i.e., SBFD time domain unit), the corresponding first bandwidth includes both downlink resources and uplink resources. For downlink transmission, the corresponding resource block combination size is determined based on at least two downlink resources within the first bandwidth. For RBGs, the RBG size is determined based on at least two downlink resources within the first bandwidth. For subband size, the subband size is determined based on at least two downlink resources within the first bandwidth.

[0177] In an embodiment of the present application, the network device performs downlink transmission on the first type of time domain unit, specifically, the network device performs downlink transmission on at least two frequency domain resources corresponding to the first type of time domain unit, and accordingly, the terminal device receives downlink transmission on the first type of time domain unit, specifically, the terminal device receives downlink transmission on at least two frequency domain resources corresponding to the first type of time domain unit.

[0178] In some embodiments, the downlink transmission is sending PDSCH, the network device sends PDSCH on at least two frequency domain resources corresponding to the first type of time domain unit, and accordingly, the terminal device receives PDSCH on at least two frequency domain resources corresponding to the first type of time domain unit.

[0179] In some embodiments, the downlink transmission is sending a downlink reference signal, which may be an SSB or a CSI-RS, etc. The downlink reference signal is used by the terminal device to report CSI. The network device sends the downlink reference signal on at least two frequency domain resources corresponding to the first type of time domain unit, and accordingly, the terminal device receives the downlink reference signal on at least two frequency domain resources corresponding to the first type of time domain unit.

[0180] In an embodiment of the present application, the combined size of resource blocks corresponding to the first type of time domain unit is determined based on a first parameter and the frequency domain resource sizes of at least two frequency domain resources within a first bandwidth, the first parameter being used to indicate one of at least two configurations, each of the at least two configurations being used to determine the combined size of resource blocks corresponding to different frequency domain resource sizes. In some implementations, the combined size of resource blocks corresponding to the first type of time domain unit is determined based on the first parameter, a first frequency domain resource indication field size, and the frequency domain resource sizes of at least two frequency domain resources within a first bandwidth, the first frequency domain resource indication field size being determined based on the frequency domain resource size of the first bandwidth and the first parameter.

[0181] Here, the method for determining the resource block combination size corresponding to the first type of time domain unit can refer to the relevant description of Figure 3 above, and the relevant description of the method for determining the resource block combination size corresponding to the first type of time domain unit in Figure 3 can be quoted here.

[0182] In some implementations, the size of each resource block combination in the first bandwidth is determined according to the size of the resource block combination corresponding to the first type of time domain unit.

[0183] Here, the method for determining the size of each resource block combination in the first bandwidth can refer to the relevant description of Figure 3 above, and the relevant description of the method for determining the size of each resource block combination in the first bandwidth in Figure 3 can be referenced here.

[0184] FIG5 is a flow chart of a method for determining a resource block combination according to an embodiment of the present application. As shown in FIG5 , the method includes some or all of the following contents:

[0185] Step 501: The network device sends a first configuration and / or a second configuration.

[0186] Step 502: The terminal device obtains a first configuration and / or a second configuration, where the first configuration is used to configure a corresponding resource block combination size for a first type of time domain unit, and the second configuration is used to configure a corresponding resource block combination size for a second type of time domain unit.

[0187] Here, the network device configures corresponding resource block combination sizes for the first type of time domain unit and the second type of time domain unit respectively through different configurations.

[0188] In some embodiments, the resource block combination is RBG, the first configuration can be a configuration performed by a high-level parameter rbg-size1, the configuration of rbg-size1 is {config1}, and the second configuration can be a configuration performed by a high-level parameter rbg-size2, the configuration of rbg-size2 is {config2}, where config1 represents configuration 1 (Configuration 1) and config2 represents configuration 2 (Configuration 2).

[0189] For example, the relationship between the RBG size, the frequency domain resource size of the first bandwidth, and the first configuration can be referred to in Table 5-1 below. According to the relationship shown in Table 5-1, the corresponding RBG size can be determined according to the frequency domain resource size of the first bandwidth and the first configuration.

[0190] Table 5-1

[0191] For example, the relationship between the RBG size, the frequency domain resource size of the first bandwidth, and the second configuration can be referred to in Table 5-2 below. According to the relationship shown in Table 5-2, the corresponding RBG size can be determined according to the frequency domain resource size of the first bandwidth and the second configuration.

[0192] Table 5-2

[0193] In some embodiments, resource blocks are combined into subbands, and the first configuration may be a configuration performed by a high-level parameter subbandSize1, where the configuration of subbandSize1 is {value1}; the second configuration may be a configuration performed by a high-level parameter subbandSize2, where the configuration of subbandSize2 is {value2}, where value1 represents value 1 and value2 represents value 2.

[0194] For example, the relationship between the subband size, the frequency domain resource size of the first bandwidth, and the first configuration can be referred to in Table 6-1 below. According to the relationship shown in Table 6-1, the corresponding subband size can be determined according to the frequency domain resource size of the first bandwidth and the first configuration.

[0195] Table 6-1

[0196] For example, the relationship between the subband size, the frequency domain resource size of the first bandwidth, and the second configuration can be referred to in Table 6-2 below. According to the relationship shown in Table 6-2, the corresponding subband size can be determined according to the frequency domain resource size of the first bandwidth and the second configuration.

[0197] Table 6-2

[0198] In some implementations, the resource blocks are grouped into PRGs, the first configuration may be configured by a higher-layer parameter PRG size1, and the configuration of PRG size1 is {2}; the second configuration may be configured by a higher-layer parameter PRG size2, and the configuration of PRG size2 is {4}.

[0199] Step 502: The terminal device determines the resource block combination size corresponding to the first type of time domain unit according to the first configuration and / or determines the resource block combination size corresponding to the second type of time domain unit according to the second configuration, where the first type of time domain unit is the SBFD time domain unit and the second type of time domain unit is the non-SBFD time domain unit.

[0200] In some embodiments, the resource blocks are combined into RBGs or subbands, and the terminal device determines the resource block combination size corresponding to the first type of time domain unit based on the frequency domain resource size of the first bandwidth and the first configuration; and / or the terminal device determines the resource block combination size corresponding to the second type of time domain unit based on the frequency domain resource size of the first bandwidth and the second configuration.

[0201] Exemplarily, the terminal device may determine the RBG size corresponding to the first type of time domain unit based on the first configuration shown in Table 5-1 and the frequency domain resource size of the first bandwidth. The terminal device may determine the RBG size corresponding to the second type of time domain unit based on the second configuration shown in Table 5-2 and the frequency domain resource size of the first bandwidth.

[0202] Exemplarily, the terminal device may determine the subband size corresponding to the first type of time domain unit based on the first configuration shown in Table 6-1 and the frequency domain resource size of the first bandwidth. The terminal device may determine the subband size corresponding to the second type of time domain unit based on the second configuration shown in Table 6-2 and the frequency domain resource size of the first bandwidth.

[0203] In some embodiments, the resource block combination is a PRG, and the terminal device directly determines the resource block combination size corresponding to the first type of time domain unit based on the first configuration; and / or, the terminal device directly determines the resource block combination size corresponding to the second type of time domain unit based on the second configuration.

[0204] In an embodiment of the present application, the terminal device determines the size of each resource block combination in the first bandwidth based on the resource block combination size corresponding to the first type of time domain unit; and / or, the terminal device determines the size of each resource block combination in the first bandwidth based on the resource block combination size corresponding to the second type of time domain unit. In other words, the terminal device divides the resource block combination within the first bandwidth based on the resource block combination size corresponding to the first type of time domain unit; and / or, the terminal device divides the resource block combination within the first bandwidth based on the resource block combination size corresponding to the second type of time domain unit.

[0205] In some implementations, the terminal device determines the size of each resource block combination in the first bandwidth based on the first number, the resource block combination size corresponding to the first type of time domain unit, and the frequency domain resource sizes of at least two frequency domain resources; the first number is the number corresponding to the first PRB in the first bandwidth.

[0206] 1) The size of the first resource block combination in the first bandwidth is determined as follows:

[0207] The size of the first resource block combination in the first bandwidth is determined according to the first number and the size of the resource block combination corresponding to the first type of time domain unit.

[0208] Exemplarily, the resource block combination size corresponding to the first type of time domain unit is P, and the terminal device divides the resource block combination within the first bandwidth according to P, where the size of the divided resource block combination is recorded as P′, and the size P′ of the first resource block combination in the first bandwidth is determined based on the above formula (1).

[0209] 2) The size of the last resource block combination in the first bandwidth is determined as follows:

[0210] If the first value is not equal to 0, the size of the last resource block combination of the first bandwidth is equal to the first value; or, if the first value is equal to 0, the size of the last resource block combination in the first bandwidth is equal to the resource block combination size corresponding to the first type of time domain unit; the first value is determined based on the first number, the resource block combination size corresponding to the first type of time domain unit and the frequency domain resource size of the first bandwidth.

[0211] Exemplarily, the resource block combination size corresponding to the first type of time domain unit is P, and the terminal device divides the resource block combination within the first bandwidth according to P, where the size of the divided resource block combination is recorded as P′, and the size P′ of the last resource block combination in the first bandwidth is determined based on the above formula (2).

[0212] 3) The size of the middle resource block combination in the first bandwidth is determined as follows:

[0213] The size of the middle resource block combination in the first bandwidth is equal to the size of the resource block combination corresponding to the first type of time domain unit.

[0214] Exemplarily, the resource block combination size corresponding to the first type of time domain unit is P, and the terminal device divides the resource block combination within the first bandwidth according to P, where the size of the divided resource block combination is recorded as P′, and the size P′ of the intermediate resource block combination in the first bandwidth is determined based on the above formula (3).

[0215] After the size of each resource block combination in the first bandwidth is determined through the above solution, the resource block combination can be divided within the first bandwidth based on the size.

[0216] In some embodiments, if there is a first resource block combination in the first bandwidth in which some PRBs do not belong to the above-mentioned frequency domain resources (which can be any one of the above-mentioned at least two frequency domain resources), then the first resource block combination is adjusted to include only some PRBs belonging to the above-mentioned frequency domain resources.

[0217] Here, the first resource block combination may be the first resource block combination of frequency domain resources, or the last resource block combination of frequency domain resources.

[0218] Exemplarily, the at least two frequency domain resources in the first bandwidth include a first downlink subband and a second downlink subband, and there is an uplink subband between the first downlink subband and the second downlink subband. After dividing the resource block combination within the first bandwidth, N resource block combinations can be obtained. Case 1) For the last resource block combination of the first downlink subband, if there are some PRBs in the resource block combination that do not belong to the first downlink subband, then the resource block combination is adjusted to include only the part of PRBs that belong to the first downlink subband. Case 2) For the first resource block combination of the second downlink subband, if there are some PRBs in the resource block combination that do not belong to the second downlink subband, then the resource block combination is adjusted to include only the part of PRBs that belong to the second downlink subband.

[0219] The above-mentioned technical solution of the embodiment of the present application configures corresponding resource block combination sizes for the first type of time domain unit (i.e., SBFD time domain unit) and the second type of time domain unit (i.e., non-SBFD time domain unit). For the first type of time domain unit (i.e., SBFD time domain unit), the corresponding resource block combination size can be determined according to its special configuration (i.e., first configuration). Similarly, for the second type of time domain unit (i.e., non-SBFD time domain unit), the corresponding resource block combination size can be determined according to its special configuration (i.e., second configuration). In this way, the method for determining the resource block combination size is enhanced, and the resource block combination size determined in this way is also accurate for the first type of time domain unit (i.e., SBFD time domain unit).

[0220] The technical solutions of the embodiments of the present application are illustrated below with reference to specific application examples.

[0221] Application Example 1

[0222] In this application example, description is made by taking the resource block combination as RBG, the first bandwidth as BWP, and the at least two frequency domain resources as two downlink subbands.

[0223] An uplink subband is configured in the middle of the BWP, and two downlink subbands are formed on either side of the uplink subband. The BWP contains 72 PRBs, of which one uplink subband contains 36 PRBs and two downlink subbands each contain 18 PRBs.

[0224] The RBG size is determined based on the frequency domain resource size (or the sum of the bandwidths) of the two downlink subbands and the configuration indicated by the first parameter rbg-size. Assuming the configuration indicated by the first parameter rbg-size is {config1}, the frequency domain resource size of the two downlink subbands is 18+18=36 PRBs. Combined with Table 3, the RBG size can be determined as: P=2, where P represents the RBG size. It should be noted that the configuration indicated by the first parameter rbg-size applies to both SBFD and non-SBFD time domain units. The RBG size for an SBFD time domain unit is determined based on the frequency domain resource size (or the sum of the bandwidths) of the two downlink subbands and the configuration indicated by the first parameter rbg-size, in combination with Table 3. The RBG size for a non-SBFD time domain unit is determined based on the frequency domain resource size of the BWP and the configuration indicated by the first parameter rbg-size, in combination with Table 3.

[0225] As shown in FIG6 , after determining that the RBG size is P=2, RBG division can be performed on the BWP according to the RBG size. The dotted line in the figure represents the RBG division boundary. P′ consecutive PRBs on the BWP are divided into one RBG. The value of P′ can be determined as follows:

[0226] 1) The size P′ of the first RBG in the BWP is determined based on the above formula (1), specifically:

[0227] in, Represents the number 3 corresponding to the first PRB in the BWP.

[0228] 2) The size P′ of the last RBG in the BWP is determined based on the above formula (2), specifically:

[0229] because,

[0230] so,

[0231] in, Represents the number 3 corresponding to the first PRB in the BWP, Indicates the number of PRBs contained in the BWP, 72.

[0232] 3) The size P′ of the middle RBG in the BWP is determined based on the above formula (3), specifically: P′=P=2.

[0233] After determining the size of P′, RBG division can be performed on the BWP accordingly.

[0234] Application Example 2

[0235] In this application example, description is made by taking the resource block combination as RBG, the first bandwidth as BWP, and the at least two frequency domain resources as two downlink subbands.

[0236] An uplink subband is configured in the middle of the BWP, and two downlink subbands are formed on either side of the uplink subband. The BWP contains 72 PRBs, of which one uplink subband contains 36 PRBs and two downlink subbands each contain 18 PRBs.

[0237] The terminal device obtains a first configuration and a second configuration, where the first configuration is for an SBFD time domain unit and the second configuration is for a non-SBFD time domain unit. The first configuration may be configured using the higher-level parameter rbg-size1, where the configuration of rbg-size1 is {config1}; the second configuration may be configured using the higher-level parameter rbg-size2, where the configuration of rbg-size2 is {config2}, where config1 represents configuration 1 and config2 represents configuration 2.

[0238] The terminal device can determine that the RBG size corresponding to the SBFD time domain unit is P=4 based on the frequency domain resource size of the BWP (72 PRBs) and the first configuration {config1}, in combination with the above Table 5-1.

[0239] Based on the frequency domain resource size of the BWP (72 PRBs) and the second configuration {config2}, the terminal device can determine that the RBG size corresponding to the non-SBFD time domain unit is: P=8 in combination with the above Table 5-2.

[0240] For the SBFD time domain unit, as shown in Figure 7, after determining the RBG size of P = 4, RBG division can be performed on the BWP based on the RBG size. The dotted line in the figure represents the RBG division boundary. P' consecutive PRBs on the BWP are divided into one RBG. The value of P' can be determined as follows:

[0241] 1) The size P′ of the first RBG in the BWP is determined based on the above formula (1), specifically:

[0242] in, Represents the number 3 corresponding to the first PRB in the BWP.

[0243] 2) The size P′ of the last RBG in the BWP is determined based on the above formula (2), specifically:

[0244] because,

[0245] so,

[0246] in, Represents the number 3 corresponding to the first PRB in the BWP, Indicates the number of PRBs contained in the BWP, 72.

[0247] 3) The size P′ of the middle RBG in the BWP is determined based on the above formula (3), specifically: P′=P=4.

[0248] After determining the size of P′, RBG division can be performed on the BWP accordingly.

[0249] For non-SBFD time domain units, as shown in Figure 7, after the RBG size is determined to be P = 8, RBG division can be performed on the BWP based on the RBG size. The dotted line in the figure represents the RBG division boundary. P' consecutive PRBs on the BWP are divided into one RBG. The value of P' can be determined as follows:

[0250] 1) The size P′ of the first RBG in the BWP is determined based on the above formula (1), specifically:

[0251] in, Represents the number 3 corresponding to the first PRB in the BWP.

[0252] 2) The size P′ of the last RBG in the BWP is determined based on the above formula (2), specifically:

[0253] because,

[0254] so,

[0255] in, Represents the number 3 corresponding to the first PRB in the BWP, Indicates the number of PRBs contained in the BWP, 72.

[0256] 3) The size P′ of the middle RBG in the BWP is determined based on the above formula (3), specifically: P′=P=8.

[0257] After determining the size of P′, RBG division can be performed on the BWP accordingly.

[0258] Application Example 3

[0259] In this application example, description is made by taking the resource block combination as PRG, the first bandwidth as BWP, and the at least two frequency domain resources as two downlink subbands as an example.

[0260] An uplink subband is configured in the middle of the BWP, and two downlink subbands are formed on either side of the uplink subband. The BWP contains 72 PRBs, of which one uplink subband contains 36 PRBs and two downlink subbands each contain 18 PRBs.

[0261] The terminal device obtains a first configuration and a second configuration, where the first configuration is for an SBFD time domain unit, and the second configuration is for a non-SBFD time domain unit. The first configuration may be configured using a higher-layer parameter PRG-size1, for example, PRG-size1 may be configured to {2}, and the second configuration may be configured using a higher-layer parameter PRG-size2, for example, PRG-size2 may be configured to {4}.

[0262] In one example, the terminal device obtains the first configuration and the second configuration in an implementation manner that: the terminal device receives the value of PRG-size1 and the value of PRG size2 sent by the network device, such as the received value of PRG-size1 is 2 and the value of PRG size2 is 4.

[0263] In one example, the terminal device obtains the first configuration and the second configuration in an implementation manner as follows: the terminal device receives the value of PRG-size1 sent by the network device and the difference between PRG size2 and PRG size1. For example, if the received value of PRG-size1 is 2, the difference between PRG size2 and PRG size1 is 2.

[0264] In one example, the terminal device may obtain the first configuration and the second configuration in the following manner: the terminal device receives the value of PRG-size1 sent by the network device; and the terminal device determines the value of PRG-size2 according to a rule. For example, the terminal device determines the value of PRG size2 based on the value of RBG size corresponding to the SBFD time domain unit, such as PRG size2 = RBG size. For another example, the ratio of PRG size2 corresponding to the SBFD time domain unit to PRG size1 corresponding to the non-SBFD time domain unit = the ratio of RBG size corresponding to the SBFD time domain unit to RBG size corresponding to the non-SBFD time domain unit.

[0265] According to the first configuration {PRG-size1}, the terminal device can determine that the PRG size corresponding to the SBFD time domain unit is: P=2.

[0266] According to the second configuration {PRG-size2}, the terminal device may determine that the PRG size corresponding to the non-SBFD time domain unit is: P=4.

[0267] For the SBFD time domain unit, as shown in Figure 8, after determining the PRG size to be P = 2, the PRG can be divided on the BWP according to the PRG size. The dotted line in the figure represents the PRG division boundary. P' consecutive PRBs on the BWP are divided into one PRG. The value of P' can be determined as follows:

[0268] 1) The size P′ of the first PRG in the BWP is determined based on the above formula (1), specifically:

[0269] in, Represents the number 3 corresponding to the first PRB in the BWP.

[0270] 2) The size P′ of the last PRG in the BWP is determined based on the above formula (2), specifically:

[0271] because,

[0272] so,

[0273] in, Represents the number 3 corresponding to the first PRB in the BWP, Indicates the number of PRBs contained in the BWP, 72.

[0274] 3) The size P′ of the intermediate PRG in the BWP is determined based on the above formula (3), specifically: P′=P=2.

[0275] After determining the size of P′, the PRG can be divided on the BWP accordingly.

[0276] For non-SBFD time domain units, as shown in Figure 8, the dotted line in the figure represents the PRG division boundary. After determining the PRG size to be P = 4, the PRG can be divided on the BWP based on the PRG size. P' consecutive PRBs on the BWP are divided into one PRG. The value of P' can be determined as follows:

[0277] 1) The size P′ of the first PRG in the BWP is determined based on the above formula (1), specifically:

[0278] in, Represents the number 3 corresponding to the first PRB in the BWP.

[0279] 2) The size P′ of the last PRG in the BWP is determined based on the above formula (2), specifically:

[0280] because,

[0281] so,

[0282] in, Represents the number 3 corresponding to the first PRB in the BWP, Indicates the number of PRBs contained in the BWP, 72.

[0283] 3) The size P′ of the intermediate PRG in the BWP is determined based on the above formula (3), specifically: P′=P=4.

[0284] After determining the size of P′, the PRG can be divided on the BWP accordingly.

[0285] Application Example 4

[0286] In this application example, description is made by taking a resource block combination as a subband, taking a first bandwidth as a BWP, and taking at least two frequency domain resources as two downlink subbands.

[0287] An uplink subband is configured in the middle of the BWP, and two downlink subbands are formed on either side of the uplink subband. The BWP contains 72 PRBs, of which one uplink subband contains 36 PRBs and two downlink subbands each contain 18 PRBs.

[0288] The subband size is determined based on the frequency domain resource size (or the sum of the bandwidths) of the two downlink subbands and the configuration indicated by the first parameter subbandSize. Assuming the configuration indicated by the first parameter subbandSize is {value1}, the frequency domain resource size of the two downlink subbands is 18+18=36 PRBs. Combined with Table 4, the subband size can be determined as: P=4, where P represents the subband size. It should be noted that the configuration indicated by the first parameter subbandSize applies to both determining the subband size corresponding to SBFD time domain units and determining the subband size corresponding to non-SBFD time domain units. For SBFD time domain units, the subband size is determined based on the frequency domain resource size (or the sum of the bandwidths) of the two downlink subbands and the configuration indicated by the first parameter subbandSize, combined with Table 4. For non-SBFD time domain units, the subband size is determined based on the frequency domain resource size of the BWP and the configuration indicated by the first parameter subbandSize, combined with Table 4.

[0289] As shown in Figure 9, after determining the subband size to be P = 4, the subband can be divided on the BWP according to the subband size. The dotted line in the figure represents the subband division boundary. P' consecutive PRBs on the BWP are divided into a subband. The value of P' can be determined as follows:

[0290] 1) The size P′ of the first subband in the BWP is determined based on the above formula (1), specifically:

[0291] in, Represents the number 3 corresponding to the first PRB in the BWP.

[0292] 2) The size P′ of the last subband in the BWP is determined based on the above formula (2), specifically:

[0293] because,

[0294] so,

[0295] in, Represents the number 3 corresponding to the first PRB in the BWP, Indicates the number of PRBs contained in the BWP, 72.

[0296] 3) The size P′ of the middle subband in the BWP is determined based on the above formula (3), specifically: P′=P=4.

[0297] After determining the size of P′, the BWP can be divided into sub-bands accordingly.

[0298] Application Example 5

[0299] In this application example, description is made by taking a resource block combination as a subband, taking a first bandwidth as a BWP, and taking at least two frequency domain resources as two downlink subbands.

[0300] An uplink subband is configured in the middle of the BWP, and two downlink subbands are formed on either side of the uplink subband. The BWP contains 72 PRBs, of which one uplink subband contains 36 PRBs and two downlink subbands each contain 18 PRBs.

[0301] The terminal device obtains a first configuration and a second configuration, where the first configuration is for an SBFD time domain unit and the second configuration is for a non-SBFD time domain unit. The first configuration may be configured by the higher-level parameter subbandSize1, where the configuration of subbandSize1 is {value1}; the second configuration may be configured by the higher-level parameter subbandSize2, where the configuration of subbandSize2 is {value2}, where value1 represents value 1 and value2 represents value 2.

[0302] Based on the frequency domain resource size of the BWP (72 PRBs) and the first configuration {value1}, and in combination with Table 6-1 above, the terminal device can determine that the subband size corresponding to the SBFD time domain unit is: P=4.

[0303] Based on the frequency domain resource size of the BWP (72 PRBs) and the second configuration {value2}, the terminal device can determine the subband size corresponding to the non-SBFD time domain unit as P=8 in combination with Table 6-2.

[0304] For the SBFD time domain unit, as shown in Figure 10, after determining the subband size of P = 4, the subband can be divided on the BWP according to the subband size. The dotted line in the figure represents the subband division boundary. P' consecutive PRBs on the BWP are divided into a subband. The value of P' can be determined as follows:

[0305] 1) The size P′ of the first subband in the BWP is determined based on the above formula (1), specifically:

[0306] in, Represents the number 3 corresponding to the first PRB in the BWP.

[0307] 2) The size P′ of the last subband in the BWP is determined based on the above formula (2), specifically:

[0308] because,

[0309] so,

[0310] in, Represents the number 3 corresponding to the first PRB in the BWP, Indicates the number of PRBs contained in the BWP, 72.

[0311] 3) The size P′ of the middle subband in the BWP is determined based on the above formula (3), specifically: P′=P=4.

[0312] After determining the size of P′, the BWP can be divided into sub-bands accordingly.

[0313] For non-SBFD time domain units, as shown in Figure 10, after determining the subband size to be P = 8, subband division can be performed on the BWP based on the subband size. The dotted line in the figure represents the subband division boundary. P′ consecutive PRBs on the BWP are divided into a subband. The value of P′ can be determined as follows:

[0314] 1) The size P′ of the first subband in the BWP is determined based on the above formula (1), specifically:

[0315] in, Represents the number 3 corresponding to the first PRB in the BWP.

[0316] 2) The size P′ of the last subband in the BWP is determined based on the above formula (2), specifically:

[0317] because,

[0318] so,

[0319] in, Represents the number 3 corresponding to the first PRB in the BWP, Indicates the number of PRBs contained in the BWP, 72.

[0320] 3) The size P′ of the middle subband in the BWP is determined based on the above formula (3), specifically: P′=P=8.

[0321] After determining the size of P′, the BWP can be divided into sub-bands accordingly.

[0322] Application Example 6

[0323] In this application example, the first bandwidth is BWP and the at least two frequency domain resources are two downlink sub-bands (downlink sub-band 1 and downlink sub-band 2) are used as an example for description.

[0324] An uplink subband is configured in the middle of the BWP, and two downlink subbands are formed on either side of the uplink subband. The BWP contains 72 PRBs, of which one uplink subband contains 36 PRBs and two downlink subbands each contain 18 PRBs.

[0325] After dividing the resource block combinations on the BWP, N resource block combinations can be obtained, among which K1 resource block combinations fall into the above-mentioned frequency domain resource 1, and K2 resource block combinations fall into the above-mentioned frequency domain resource 2.

[0326] Among the K1 resource block combinations, the first resource block combination may have some PRBs that do not belong to frequency domain resource 1. In this case, the first resource block combination of frequency domain resource 1 only includes the PRBs belonging to the frequency domain resource in the first resource block combination of the K1 resource block combinations. Similarly, among the K1 resource block combinations, the last resource block combination may have some PRBs that do not belong to frequency domain resource 1. In this case, the last resource block combination of frequency domain resource 1 only includes the PRBs belonging to the frequency domain resource in the last resource block combination of the K1 resource block combinations. In addition, the middle resource block combination of frequency domain resource 1 is consistent with the middle resource block combination of the above K1 resource block combinations. Similarly, among the K2 resource block combinations, the first resource block combination may have some PRBs that do not belong to frequency domain resource 2. In this case, the first resource block combination of frequency domain resource 2 only includes the PRBs belonging to the frequency domain resource in the first resource block combination of the K2 resource block combinations. Similarly, in the K2 resource block combinations, the last resource block combination may have some PRBs that do not belong to frequency domain resource 2. In this case, the last resource block combination of frequency domain resource 2 only includes the PRBs belonging to the frequency domain resource in the last resource block combination of the K2 resource block combinations. In addition, the middle resource block combination of frequency domain resource 2 is consistent with the middle resource block combination in the above K2 resource block combinations.

[0327] For example, as shown in Figure 11, K1 = 10. After resource block combinations are divided on the BWP, the 10 resource block combinations fall into frequency domain resource 1. PRB 21 in the last resource block combination of these 10 resource block combinations does not belong to downlink subband 1. Therefore, the last resource block combination of downlink subband 1 only contains PRB 20, and the other resource block combinations of downlink subband 1 are consistent with the resource block combinations of the BWP. K2 = 10. After resource block combinations are divided on the BWP, the 10 resource block combinations fall into frequency domain resource 2. PRB 56 in the first resource block combination of these 10 resource block combinations does not belong to downlink subband 2. Therefore, the first resource block combination of downlink subband 2 only contains PRB 57, and the other resource block combinations of downlink subband 2 are consistent with the resource block combinations of the BWP.

[0335] In some implementations, if there are multiple resource block combination sizes in the resource block combination size set that meet the first condition, the resource block combination size corresponding to the first type of time domain unit is the minimum resource block combination size that meets the first condition.

[0336] In some embodiments, if the frequency domain resource indication domain size determined according to the first resource block combination size is less than or equal to the first frequency domain resource indication domain size, then the resource block combination size corresponding to the first type of time domain unit is the first resource block combination size, and the first resource block combination size is determined according to the frequency domain resource size of the at least two frequency domain resources and the first parameter; if the frequency domain resource indication domain size determined according to the first resource block combination size is greater than the first frequency domain resource indication domain size, then the resource block combination size corresponding to the first type of time domain unit is the second resource block combination size, and the second resource block combination size is determined according to the frequency domain resource size of the first bandwidth and the first parameter.

[0337] In some implementations, the determining unit 1201 is configured to determine the size of each resource block combination in the first bandwidth according to the resource block combination size corresponding to the first type of time domain unit.

[0338] In some embodiments, the determination unit 1201 is used to determine the size of each resource block combination in the first bandwidth based on the first number, the resource block combination size corresponding to the first type of time domain unit, and the frequency domain resource size of the at least two frequency domain resources; the first number is the number corresponding to the first PRB in the first bandwidth.
