Description

Technical Field

[0001] This disclosure relates to the field of wireless communication technology, and in particular to a subband configuration method, user equipment, and network equipment. Background Technology

[0002] Full-duplex technology allows simultaneous uplink and downlink information transmission on the same frequency band. Sub-band Full Duplex (SBFD) technology refers to the simultaneous transmission of uplink and downlink information on the same frequency band using non-overlapping frequency domain resources. For example, ... Figure 1 As shown, in a TDD (Time Division Duplexing) frequency band, the time resources on a carrier other than the uplink time resources are divided into non-overlapping uplink and downlink sub-bands in the frequency domain. These time resources are called SBFD time resources. Uplink information can be transmitted in the uplink sub-band within the SBFD time resource, and downlink information can be transmitted in the downlink sub-band within the SBFD time resource. The base station can simultaneously transmit and receive on the SBFD time resource, while the terminal maintains a mode of only transmitting or receiving.

[0003] One method for a base station to configure the frequency domain location of uplink and downlink subbands to a terminal is as follows: For each configured subcarrier interval, location and bandwidth parameters are configured for each uplink and downlink subband, indicating a resource indicator value (RIV) used to calculate the starting resource block and the number of resource blocks for the corresponding subband. The RIV range is [0, 37949], therefore, each location and bandwidth parameter needs to support indicating one of 37950 values. The location and bandwidth parameters are carried by System Information Block 1 (SIB1). This method incurs significant signaling overhead. Summary of the Invention

[0004] In this embodiment of the disclosure, when configuring uplink and downlink subbands for full-duplex subbands, the frequency domain position configuration signaling for the uplink and downlink subbands includes: frequency domain position configuration parameters for the uplink and downlink subbands and subcarrier spacing parameters. The frequency domain position configuration parameters of the subbands located at the carrier edge in the uplink or downlink subbands are used to configure one of the subband's bandwidth information, frequency domain start resource block position, and frequency domain end resource block position. Based on the frequency domain position configuration parameters of the uplink and downlink subbands, the frequency domain position of the uplink and downlink subbands within the carrier corresponding to the subcarrier spacing configured by the subcarrier spacing parameters of the uplink and downlink subbands is determined. It is not necessary for the frequency domain position configuration parameters of each uplink and downlink subband to support indicating the RIV range, thus saving signaling overhead.

[0085] The frequency domain location types of the uplink and downlink subbands in full-duplex subbands include the following three cases.

[0086] Frequency domain location type one: such as Figure 2 As shown in (a), the starting resource block position in the frequency domain of the uplink subband is the same as the position of the lowest frequency resource block of the carrier corresponding to the subcarrier spacing configured in the uplink subband's subcarrier spacing parameters. There is one downlink subband, and the ending resource block position in the frequency domain of the downlink subband is the same as the position of the highest frequency resource block of the carrier corresponding to the subcarrier spacing configured in the downlink subband's subcarrier spacing parameters. The uplink subband is located on the lower frequency side of the carrier frequency domain, and the downlink subband is located on the higher frequency side of the carrier frequency domain.

[0087] For frequency domain location type one, the frequency domain start resource block position of the uplink sub-band and the frequency domain end resource block position of the downlink sub-band do not need to be determined based on the frequency domain location configuration parameters of the uplink and downlink sub-bands.

[0088] Frequency domain location type two: such as Figure 2 As shown in (b), the location of the frequency domain end resource block of the uplink sub-band is the same as the location of the resource block with the highest frequency corresponding to the subcarrier spacing configured in the uplink sub-band's subcarrier spacing parameters. There is one downlink sub-band, and the location of the frequency domain start resource block of the downlink sub-band is the same as the location of the resource block with the lowest frequency corresponding to the subcarrier spacing configured in the downlink sub-band's subcarrier spacing parameters. The downlink sub-band is located on the lower frequency side of the carrier frequency domain, and the uplink sub-band is located on the higher frequency side of the carrier frequency domain.

[0089] For frequency domain location type two, the frequency domain end resource block location of the uplink sub-band and the frequency domain start resource block location of the downlink sub-band do not need to be determined based on the frequency domain location configuration parameters of the uplink and downlink sub-bands.

[0090] Frequency domain location type three: such as Figure 2As shown in (c), the starting resource block position in the frequency domain of the uplink subband is different from the position of the lowest frequency resource block corresponding to the subcarrier spacing configured by the uplink subband's subcarrier spacing parameters, and the ending resource block position in the frequency domain of the uplink subband is different from the position of the highest frequency resource block corresponding to the subcarrier spacing configured by the uplink subband's subcarrier spacing parameters. The starting resource block position in the frequency domain of the first downlink subband is the same as the position of the lowest frequency resource block corresponding to the subcarrier spacing configured by the downlink subband's subcarrier spacing parameters, and the ending resource block position in the frequency domain of the second downlink subband is the same as the position of the highest frequency resource block corresponding to the subcarrier spacing configured by the downlink subband's subcarrier spacing parameters. The uplink subband is located in the middle region of the carrier frequency domain, and there are two downlink subbands, located on the low-frequency side and the high-frequency side of the carrier frequency domain, respectively.

[0091] For frequency domain location type three, the starting resource block position of the first downlink sub-band and the ending resource block position of the second downlink sub-band do not need to be determined based on the frequency domain location configuration parameters of the downlink sub-band.

[0092] In addition, there can be a certain guard interval between the uplink subband and the downlink subband in full-duplex subband, which is used to reduce the self-interference of the base station's transmission in the downlink subband to the reception in the uplink subband, or to reduce the cross-link interference of the terminal's reception in the downlink subband caused by the transmission of other terminals in the uplink subband.

[0093] The following describes in detail, with reference to the accompanying drawings, various configuration methods for uplink and downlink subbands in full-duplex subband, all of which can save signaling overhead. The network devices in each embodiment are, for example, access network devices such as base stations, and user equipment includes terminals such as mobile phones and computers, but are not limited to these examples.

[0094] Figure 3 A flowchart illustrating a sub-band configuration method according to some embodiments of this disclosure is shown.

[0095] like Figure 3 As shown, the subband configuration method of this embodiment includes one or more of the following steps. The network device and the user equipment can each independently execute their respective subband configuration methods.

[0096] In step 310, the network device sends uplink and downlink subband frequency domain position configuration signaling to the user equipment, including: uplink and downlink subband frequency domain position configuration parameters and subcarrier spacing parameters. The frequency domain position configuration parameters of the uplink or downlink subband located at the carrier edge are used to configure one of the subband's bandwidth information, frequency domain start resource block position, and frequency domain end resource block position. This instructs the user equipment to determine the frequency domain position of the uplink subband within the carrier corresponding to the subcarrier spacing configured by the uplink subband's subcarrier spacing parameters, based on the uplink subband's frequency domain position configuration parameters, and to determine the frequency domain position of the downlink subband within the carrier corresponding to the subcarrier spacing configured by the downlink subband's subcarrier spacing parameters, based on the downlink subband's frequency domain position configuration parameters.

[0097] The frequency domain position configuration parameters of uplink and downlink sub-bands refer to the frequency domain position configuration parameters of uplink / downlink sub-bands, which are used to configure the frequency domain position information of uplink / downlink sub-bands. These parameters have various forms, which will be described in detail in subsequent embodiments.

[0098] In step 320, the user equipment receives frequency domain position configuration signaling for uplink and downlink subbands sent by the network device, including frequency domain position configuration parameters for uplink and downlink subbands and subcarrier spacing parameters. The frequency domain position configuration parameters of the uplink or downlink subband located at the carrier edge are used to configure one of the subband's bandwidth information, frequency domain start resource block position, and frequency domain end resource block position.

[0099] In step 330, the user equipment (UE) determines the frequency domain position of the uplink sub-band within the carrier corresponding to the subcarrier spacing configured by the uplink sub-band frequency domain position configuration parameters, and determines the frequency domain position of the downlink sub-band within the carrier corresponding to the subcarrier spacing configured by the downlink sub-band frequency domain position configuration parameters. This ensures that the UE and network equipment have a consistent understanding of the frequency domain positions of the uplink and downlink sub-bands, enabling coordinated transmission and reception of information on the uplink and downlink sub-bands.

[0100] Determining the frequency domain position of the uplink and downlink subbands includes, for example: determining the frequency domain position type based on the frequency domain position configuration parameters of the uplink or downlink subbands; and determining the frequency domain position of the uplink and downlink subbands within the carrier corresponding to the subcarrier spacing configured by the subcarrier spacing parameters based on the frequency domain position configuration parameters of the uplink and downlink subbands and the frequency domain position type.

[0101] In the subsequent embodiments, in embodiment group 1, the frequency domain position type is determined according to the frequency domain position configuration parameters of the uplink sub-band, and in embodiment group 2, the frequency domain position type is determined according to the frequency domain position configuration parameters of the downlink sub-band.

[0102] In this embodiment of the disclosure, when configuring uplink and downlink subbands for full-duplex subbands, the frequency domain position configuration signaling for the uplink and downlink subbands includes: frequency domain position configuration parameters for the uplink and downlink subbands and subcarrier spacing parameters. The frequency domain position configuration parameters of the subbands located at the carrier edge in the uplink or downlink subbands are used to configure one of the subband's bandwidth information, frequency domain start resource block position, and frequency domain end resource block position. Based on the frequency domain position configuration parameters of the uplink and downlink subbands, the frequency domain position of the uplink and downlink subbands within the carrier corresponding to the subcarrier spacing configured by the subcarrier spacing parameters of the uplink and downlink subbands is determined. It is not necessary for the frequency domain position configuration parameters of each uplink and downlink subband to support indicating the RIV range, thus saving signaling overhead.

[0103] Example group 1 includes, for example, examples 1.1 to 1.8, wherein examples 1.1 to 1.6 relate to an uplink subband frequency domain position configuration method, wherein the frequency domain position type is determined based on the uplink subband frequency domain position configuration parameters, and examples 1.7 to 1.8 relate to a downlink subband frequency domain position configuration method. Any one of examples 1.1 to 1.6 can be used in combination with any one of examples 1.7 to 1.8.

[0104] Example group 2 includes, for example, examples 2.1 to 2.5. Examples 2.1 to 2.2 relate to a downlink subband frequency domain position configuration method, wherein the frequency domain position type is determined based on the downlink subband frequency domain position configuration parameters. Examples 2.3 to 2.5 relate to an uplink subband frequency domain position configuration method. Any one of examples 2.1 to 2.2 can be used in combination with any one of examples 2.3 to 2.5. Any one of examples 2.1 to 2.2 can also be used in combination with any one of examples 1.1 to 1.6.

[0105] Each of the above-described groups of embodiments may include one or more embodiments. The specific descriptions of each group of embodiments are as follows.

[0106] Example 1.1 (Uplink Subband Frequency Domain Position Configuration Method)

[0107] The frequency domain location configuration parameters of the uplink subband can be selected from the following parameters: uplink subband location and bandwidth parameters, uplink subband first bandwidth parameters, and uplink subband second bandwidth parameters.

[0108] When choosing to configure either the first bandwidth parameter or the second bandwidth parameter of the uplink subband, signaling overhead can be saved compared to configuring both the bandwidth and start position of the uplink subband simultaneously.

[0109] When the uplink subband's frequency domain location configuration parameters include the uplink subband's first bandwidth parameter, it indicates that it is frequency domain location type one. The uplink subband's frequency domain start resource block location is the same as the location of the lowest frequency resource block of the carrier corresponding to the subcarrier spacing configured in the uplink subband's subcarrier spacing parameters. The uplink subband's first bandwidth parameter is used to configure the uplink subband's bandwidth. Given that the uplink subband's frequency domain start resource block location and bandwidth are determined, the uplink subband's frequency domain end resource block location can be determined by calculating the number of frequency domain resource blocks within the bandwidth plus the uplink subband's frequency domain start resource block location.

[0110] When the uplink subband's frequency domain location configuration parameters include the uplink subband's second bandwidth parameter, it indicates frequency domain location type two. The uplink subband's frequency domain end resource block location is the same as the location of the resource block with the highest frequency corresponding to the subcarrier spacing configured in the uplink subband's subcarrier spacing parameters. The uplink subband's second bandwidth parameter is used to configure the uplink subband's bandwidth. Given the determined uplink subband's frequency domain end resource block location and bandwidth, the uplink subband's frequency domain start resource block location can be determined by subtracting the number of frequency domain resource blocks within the bandwidth from the uplink subband's frequency domain end resource block location.

[0111] When the uplink subband frequency domain location configuration parameters include the uplink subband location and bandwidth parameters, it indicates frequency domain location type three. The uplink subband location and bandwidth parameters are used to configure the uplink subband frequency domain offset and bandwidth. The uplink subband frequency domain offset represents the number of resource blocks offset between the uplink subband's frequency domain starting resource block and the lowest frequency resource block corresponding to the carrier space configured in the uplink subband subcarrier spacing parameters. The uplink subband location and bandwidth parameters can, for example, indicate the RIV value, and there is a pre-defined correspondence between the RIV value and the uplink subband frequency domain offset and bandwidth.

[0112] Given the resource block with the lowest frequency corresponding to the carrier spacing configured with the uplink subband subcarrier spacing parameters, and the frequency domain offset of the uplink subband, the resource block with the lowest frequency corresponding to the carrier spacing configured with the uplink subband subcarrier spacing parameters is selected. Add the frequency domain offset of the sub-band The calculation can determine the frequency domain starting resource block of the uplink subband. The formula can be expressed as: Given the location of the starting resource block and bandwidth of the uplink subband in the frequency domain, the location of the ending resource block in the frequency domain can be determined by calculating the number of frequency domain resource blocks within the bandwidth, based on the starting resource block location in the frequency domain of the uplink subband.

[0113] Referring to the above description, the frequency domain location configuration signaling for the uplink subband would be, for example:

[0114] ULSubband ::= SEQUENCE {

[0115] subcarrierSpacing SubcarrierSpacing,

[0116] frequencyLocation CHOICE {

[0117] locationAndBandwidth INTEGER (0..37949),

[0118] bandwidthLow INTEGER (1..maxNrofPhysicalResourceBlocks),

[0119] bandwidthHigh INTEGER (1..maxNrofPhysicalResourceBlocks),

[0120] },

[0121] }

[0122] Wherein, ULSubband represents the frequency domain location configuration signaling of the uplink subband, SubcarrierSpacing represents the subcarrier spacing parameter, frequencyLocation represents the frequency domain location configuration parameter of the uplink subband, CHOICE represents selecting one from the options, locationAndBandwidth represents the location and bandwidth parameters of the uplink subband, 0..37949 is an example value range, and the value range can also be other values ​​depending on the configuration supported by the number of frequency domain resource blocks included in the uplink subband, bandwidthLow represents the first bandwidth parameter of the uplink subband, bandwidthHigh represents the second bandwidth parameter of the uplink subband, and maxNrofPhysicalResourceBlocks represents the maximum number of frequency domain resource blocks of the uplink subband that can be configured. Assuming that the BWP (Bandwidth Part) size is 275, the value of maxNrofPhysicalResourceBlock can be 275, and the value range can also be other values ​​depending on the configuration supported by the number of frequency domain resource blocks included in the uplink subband.

[0123] Example 1.2 (Uplink Subband Frequency Domain Position Configuration Method)

[0124] The frequency domain location configuration parameters of the uplink subband include optional parameters, including the location and bandwidth parameters of the uplink subband, the first bandwidth parameter of the uplink subband, and the second bandwidth parameter of the uplink subband.

[0125] When choosing to configure either the first bandwidth parameter or the second bandwidth parameter of the uplink subband, signaling overhead can be saved compared to configuring both the bandwidth and start position of the uplink subband simultaneously.

[0126] When the uplink subband's frequency domain location configuration parameters include the uplink subband's first bandwidth parameter, it indicates that it is frequency domain location type one. The uplink subband's frequency domain start resource block location is the same as the location of the lowest frequency resource block of the carrier corresponding to the subcarrier spacing configured in the uplink subband's subcarrier spacing parameters. The uplink subband's first bandwidth parameter is used to configure the uplink subband's bandwidth. Given that the uplink subband's frequency domain start resource block location and bandwidth are determined, the uplink subband's frequency domain end resource block location can be determined by calculating the number of frequency domain resource blocks within the bandwidth plus the uplink subband's frequency domain start resource block location.

[0127] When the uplink subband's frequency domain location configuration parameters include the uplink subband's second bandwidth parameter, it indicates frequency domain location type two. The uplink subband's frequency domain end resource block location is the same as the location of the resource block with the highest frequency corresponding to the subcarrier spacing configured in the uplink subband's subcarrier spacing parameters. The uplink subband's second bandwidth parameter is used to configure the uplink subband's bandwidth. Given the determined uplink subband's frequency domain end resource block location and bandwidth, the uplink subband's frequency domain start resource block location can be determined by subtracting the number of frequency domain resource blocks within the bandwidth from the uplink subband's frequency domain end resource block location.

[0128] When the uplink subband frequency domain location configuration parameters include the uplink subband location and bandwidth parameters, it indicates frequency domain location type three. The uplink subband location and bandwidth parameters are used to configure the uplink subband frequency domain offset and bandwidth. The uplink subband frequency domain offset represents the number of resource blocks offset between the uplink subband's frequency domain starting resource block and the lowest frequency resource block corresponding to the carrier space configured in the uplink subband subcarrier spacing parameters. The uplink subband location and bandwidth parameters can, for example, indicate the RIV value, and there is a pre-defined correspondence between the RIV value and the uplink subband frequency domain offset and bandwidth.

[0129] Given the resource block with the lowest frequency corresponding to the carrier spacing configured with the uplink subband subcarrier spacing parameters, and the frequency domain offset of the uplink subband, the resource block with the lowest frequency corresponding to the carrier spacing configured with the uplink subband subcarrier spacing parameters is selected. Add the frequency domain offset of the sub-band The calculation can determine the frequency domain starting resource block of the uplink subband. The formula can be expressed as: Given the location of the starting resource block and bandwidth of the uplink subband in the frequency domain, the location of the ending resource block in the frequency domain can be determined by calculating the number of frequency domain resource blocks within the bandwidth, based on the starting resource block location in the frequency domain of the uplink subband.

[0130] Referring to the above description, the frequency domain location configuration signaling for the uplink subband would be, for example:

[0131] ULSubband ::= SEQUENCE {

[0132] subcarrierSpacing SubcarrierSpacing,

[0133] locationAndBandwidth INTEGER (0..37949), OPTIONAL,

[0134] bandwidthLow INTEGER (1..maxNrofPhysicalResourceBlocks), OPTIONAL,

[0135] bandwidthHigh INTEGER (1..maxNrofPhysicalResourceBlocks), OPTIONAL,

[0136] }

[0137] In this context, OPTIONAL indicates an optional parameter. The meanings of other symbols are described in Example 1.1 and will not be repeated here.

[0139] The uplink subband frequency domain location configuration parameters include: uplink subband location and bandwidth parameters, used to configure the uplink subband frequency domain offset and bandwidth. The uplink subband frequency domain offset represents the number of resource blocks offset between the uplink subband's frequency domain starting resource block and the lowest frequency resource block of the carrier corresponding to the subcarrier spacing configured in the uplink subband's subcarrier spacing parameters. The uplink subband location and bandwidth parameters can, for example, indicate the RIV value, and there is a pre-defined correspondence between the RIV value and the uplink subband frequency domain offset and bandwidth.

[0140] Given the resource block with the lowest frequency corresponding to the carrier spacing configured with the uplink subband subcarrier spacing parameters, and the frequency domain offset of the uplink subband, the resource block with the lowest frequency corresponding to the carrier spacing configured with the uplink subband subcarrier spacing parameters is selected. Add the frequency domain offset of the sub-band The calculation can determine the frequency domain starting resource block of the uplink subband. The formula can be expressed as: Given the location of the starting resource block and bandwidth of the uplink subband in the frequency domain, the location of the ending resource block in the frequency domain can be determined by calculating the number of frequency domain resource blocks within the bandwidth, based on the starting resource block location in the frequency domain of the uplink subband.

[0141] Based on the determined frequency domain location of the uplink subband, the specific frequency domain location type can be identified. Using the same parameters to configure the frequency domain location of the uplink subband for different frequency domain location types simplifies the complexity of configuration signaling.

[0142] Referring to the above description, the frequency domain location configuration signaling for the uplink subband would be, for example:

[0143] ULSubband ::= SEQUENCE {

The uplink subband frequency domain end resource block position parameters are used to configure the uplink subband frequency domain end resource block position.

[0152] If the uplink subband frequency domain position configuration parameters include the uplink subband frequency domain start resource block position parameters, it indicates that it is frequency domain position type two. The uplink subband frequency domain end resource block position is the same as the resource block position of the carrier with the highest frequency corresponding to the subcarrier spacing configured by the uplink subband subcarrier spacing parameters. The uplink subband frequency domain start resource block position parameters are used to configure the uplink subband frequency domain start resource block position.

[0153] When the frequency domain position configuration parameters of the uplink subband include the frequency domain end resource block position parameter and the frequency domain start resource block position parameter of the uplink subband, it indicates that it is frequency domain position type three.

[0154] In addition, the frequency domain start resource block location parameter of the uplink subband can also be used to indicate the frequency domain offset of the frequency domain start resource block of the uplink subband. This offset represents the number of resource blocks offset between the starting resource block of the uplink subband's frequency domain and the resource block with the lowest frequency corresponding to the carrier spacing configured by the uplink subband's subcarrier spacing parameters. The resource block with the lowest frequency corresponding to the carrier spacing configured by the uplink subband's subcarrier spacing parameters... Add the frequency domain offset of the frequency domain starting resource block of the sub-band The calculation can determine the frequency domain starting resource block of the uplink subband. The formula can be expressed as: .

[0155] In addition, the frequency domain end resource block location parameter of the uplink subband can also be used to indicate the frequency domain offset of the frequency domain end resource block of the uplink subband.

[0164] The frequency domain location configuration parameters for the uplink subband include optional parameters, such as the frequency domain start resource block location parameter of the uplink subband and the third bandwidth parameter of the uplink subband.

[0165] When selecting to configure the frequency domain start resource block location parameter or the third bandwidth parameter of the uplink subband, signaling overhead can be saved compared to configuring both the bandwidth and start position of the uplink subband simultaneously.

[0166] When the uplink subband's frequency domain location configuration parameters include the uplink subband's third bandwidth parameter, it indicates that it is frequency domain location type one. The uplink subband's frequency domain start resource block location is the same as the location of the lowest frequency resource block of the carrier corresponding to the subcarrier spacing configured in the uplink subband's subcarrier spacing parameters. The uplink subband's third bandwidth parameter is used to configure the uplink subband's bandwidth. Given that the uplink subband's frequency domain start resource block location and bandwidth are determined, the uplink subband's frequency domain end resource block location can be determined by calculating the number of frequency domain resource blocks within the bandwidth plus the uplink subband's frequency domain start resource block location.

[0167] If the uplink subband frequency domain position configuration parameters include the uplink subband frequency domain start resource block position parameters, it indicates that it is frequency domain position type two. The uplink subband frequency domain end resource block position is the same as the resource block position of the carrier with the highest frequency corresponding to the subcarrier spacing configured by the uplink subband subcarrier spacing parameters. The uplink subband frequency domain start resource block position parameters are used to configure the uplink subband frequency domain start resource block position.

[0168] When the uplink subband's frequency domain location configuration parameters include the uplink subband's third bandwidth parameter and the uplink subband's frequency domain start resource block location parameter, it indicates a frequency domain location type three. The uplink subband's frequency domain start resource block location parameter is used to configure the uplink subband's frequency domain start resource block location, and the uplink subband's third bandwidth parameter is used to configure the uplink subband's bandwidth. Given that the uplink subband's frequency domain start resource block location and bandwidth are determined, the uplink subband's frequency domain end resource block location can be determined by calculating the number of frequency domain resource blocks within the bandwidth, based on the uplink subband's frequency domain start resource block location.

[0169] Referring to the above description, the frequency domain location configuration signaling for the uplink subband would be, for example:

[0170] ULSubband ::= SEQUENCE {

[0171] subcarrierSpacing SubcarrierSpacing,

[0172] startRB INTEGER (1..maxNrofPhysicalResourceBlocks), OPTIONAL,

[0173] bandwidth INTEGER (1..maxNrofPhysicalResourceBlocks), OPTIONAL,

[0174] }

[0175] Here, bandwidth represents the third bandwidth parameter of the uplink subband. The above provides an exemplary range of values ​​for bandwidth. Depending on the configuration supported by the number of frequency domain resource blocks included in the uplink subband, the range can also be other numerical ranges. The meanings of other symbols are described in Example Group 1.4, and will not be repeated here.

[0176] According to any one of the embodiments 1.1 to 1.5, it is possible to configure the uplink subband to any frequency domain position of the carrier, thereby adapting to different downlink transmission situations and downlink transmission power of adjacent carriers, and having good configuration flexibility.

[0177] Example group 1.6 includes example groups 1.6-1, 1.6-2, and 1.6-3, which are described below.

[0178] Example 1.6-1 (Uplink Subband Frequency Domain Position Configuration Method)

[0179] The frequency domain position configuration parameter of the uplink subband can be selected from the following parameters: the fourth bandwidth parameter of the uplink subband, the fifth bandwidth parameter of the uplink subband, and the sixth bandwidth parameter of the uplink subband.

[0180] When selecting to configure a specific bandwidth parameter for an uplink subband, signaling overhead can be saved compared to configuring both the bandwidth and start position of the uplink subband simultaneously.

[0181] When the uplink subband's frequency domain location configuration parameters include the uplink subband's fourth bandwidth parameter, it indicates that it is frequency domain location type one. The uplink subband's frequency domain start resource block location is the same as the location of the lowest frequency resource block corresponding to the carrier interval configured in the uplink subband's subcarrier spacing parameters. The uplink subband's fourth bandwidth parameter is used to configure the uplink subband's bandwidth. Given that the uplink subband's frequency domain start resource block location and bandwidth are determined, the uplink subband's frequency domain end resource block location can be determined by calculating the number of frequency domain resource blocks within the bandwidth plus the uplink subband's frequency domain start resource block location.

[0182] When the uplink subband's frequency domain location configuration parameters include the fifth bandwidth parameter, it indicates frequency domain location type two. The location of the uplink subband's frequency domain end resource block is the same as the location of the resource block with the highest frequency corresponding to the subcarrier spacing configured in the uplink subband's subcarrier spacing parameters. The fifth bandwidth parameter of the uplink subband is used to configure the bandwidth of the uplink subband. Given the determined uplink subband's frequency domain end resource block location and bandwidth, the uplink subband's frequency domain start resource block location can be determined by subtracting the number of frequency domain resource blocks within the bandwidth from the uplink subband's frequency domain end resource block location.

[0183] When the uplink subband's frequency domain position configuration parameters include the sixth bandwidth parameter, it indicates a frequency domain position type three. The uplink subband's frequency domain position is symmetrical about the carrier frequency domain corresponding to the subcarrier spacing configured with respect to the uplink subband's subcarrier spacing parameters. The sixth bandwidth parameter of the uplink subband is used to configure the bandwidth of the uplink subband. Given the determined characteristics of the uplink subband's frequency domain symmetry and bandwidth, the uplink subband's frequency domain position can be determined.

[0184] Referring to the above description, the frequency domain location configuration signaling for the uplink subband would be, for example:

[0185] ULSubband ::= SEQUENCE {

[0186] subcarrierSpacing SubcarrierSpacing,

[0187] frequencyLocation CHOICE {

[0188] bandwidthMiddle INTEGER (1..maxNrofPhysicalResourceBlocks),

[0189] bandwidthLow INTEGER (1..maxNrofPhysicalResourceBlocks),

[0190] bandwidthHigh INTEGER (1..maxNrofPhysicalResourceBlocks),

[0192] }

[0193] Wherein, bandwidthLow, bandwidthHigh, and bandwidthMidddle represent the fourth, fifth, and sixth bandwidth parameters of the uplink subband, respectively. The meanings of other symbols are described in Example Group 1.1, and will not be repeated here.

[0194] Example 1.6-2 (Uplink Subband Frequency Domain Position Configuration Method)

[0195] The frequency domain location configuration parameters of the uplink subband include optional parameters, including the fourth bandwidth parameter, the fifth bandwidth parameter, and the sixth bandwidth parameter of the uplink subband.

[0196] When selecting to configure a specific bandwidth parameter for an uplink subband, signaling overhead can be saved compared to configuring both the bandwidth and start position of the uplink subband simultaneously.

[0197] When the uplink subband's frequency domain location configuration parameters include the uplink subband's fourth bandwidth parameter, it indicates that it is frequency domain location type one. The uplink subband's frequency domain start resource block location is the same as the location of the lowest frequency resource block corresponding to the carrier interval configured in the uplink subband's subcarrier spacing parameters. The uplink subband's fourth bandwidth parameter is used to configure the uplink subband's bandwidth. Given that the uplink subband's frequency domain start resource block location and bandwidth are determined, the uplink subband's frequency domain end resource block location can be determined by calculating the number of frequency domain resource blocks within the bandwidth plus the uplink subband's frequency domain start resource block location.

[0198] When the uplink subband's frequency domain location configuration parameters include the fifth bandwidth parameter, it indicates frequency domain location type two. The location of the uplink subband's frequency domain end resource block is the same as the location of the resource block with the highest frequency corresponding to the subcarrier spacing configured in the uplink subband's subcarrier spacing parameters. The fifth bandwidth parameter of the uplink subband is used to configure the bandwidth of the uplink subband. Given the determined uplink subband's frequency domain end resource block location and bandwidth, the uplink subband's frequency domain start resource block location can be determined by subtracting the number of frequency domain resource blocks within the bandwidth from the uplink subband's frequency domain end resource block location.

[0199] When the uplink subband's frequency domain position configuration parameters include the sixth bandwidth parameter, it indicates a frequency domain position type three. The uplink subband's frequency domain position is symmetrical about the carrier frequency domain corresponding to the subcarrier spacing configured with respect to the uplink subband's subcarrier spacing parameters. The sixth bandwidth parameter of the uplink subband is used to configure the bandwidth of the uplink subband. Given the determined characteristics of the uplink subband's frequency domain symmetry and bandwidth, the uplink subband's frequency domain position can be determined.

[0200] Referring to the above description, the frequency domain location configuration signaling for the uplink subband would be, for example:

[0201] ULSubband ::= SEQUENCE {

[0202] subcarrierSpacing SubcarrierSpacing,

[0203] bandwidthMiddle INTEGER (1..maxNrofPhysicalResourceBlocks),OPTIONAL,

[0204] bandwidthLow INTEGER (1..maxNrofPhysicalResourceBlocks), OPTIONAL,

[0205] bandwidthHigh INTEGER (1..maxNrofPhysicalResourceBlocks), OPTIONAL,

[0206] }

[0207] In this context, OPTIONAL indicates an optional parameter. The meanings of other symbols are described in Example 1.6-1 and will not be repeated here.

[0208] Example 1.6-3 (Uplink Subband Frequency Domain Position Configuration Method)

[0209] The frequency domain position configuration parameters of the uplink subband include the seventh bandwidth parameter of the uplink subband and the uplink subband position indication parameter. The seventh bandwidth parameter of the uplink subband is used to configure the bandwidth of the uplink subband. The uplink subband position indication parameter is used to indicate the uplink subband position type and is configured as a first value, a second value, or a third value.

[0210] When selecting to configure the bandwidth and location type of the uplink subband, signaling overhead can be saved compared to configuring both the bandwidth and start location of the uplink subband simultaneously.

[0211] The first value indicates that the frequency domain start resource block position of the uplink subband is the same as the position of the lowest frequency resource block of the carrier corresponding to the subcarrier spacing configured by the uplink subband's subcarrier spacing parameters, indicating that it is frequency domain position type one; the second value indicates that the frequency domain end resource block position of the uplink subband is the same as the position of the highest frequency resource block of the carrier corresponding to the subcarrier spacing configured by the uplink subband's subcarrier spacing parameters, indicating that it is frequency domain position type two; the third value indicates that the frequency domain start resource block position of the uplink subband is not the same as the position of the lowest frequency resource block of the carrier corresponding to the subcarrier spacing configured by the uplink subband's subcarrier spacing parameters, and the frequency domain end resource block position of the uplink subband is not the same as the position of the highest frequency resource block of the carrier corresponding to the subcarrier spacing configured by the uplink subband's subcarrier spacing parameters, indicating that it is frequency domain position type three; when the uplink subband position indication parameter is configured with the third value, the uplink subband is frequency domain symmetrical about the carrier corresponding to the subcarrier spacing configured by the uplink subband's subcarrier spacing parameters.

[0212] Referring to the above description, the frequency domain location configuration signaling for the uplink subband would be, for example:

[0213] ULSubband ::= SEQUENCE {

[0214] subcarrierSpacing SubcarrierSpacing,

[0215] bandwidth INTEGER (1..maxNrofPhysicalResourceBlocks),

[0216] location ENUMERATED {low, middle, high}

[0217] }

[0218] Wherein, bandwidth represents the seventh bandwidth parameter of the uplink subband, location represents the uplink subband location indication parameter, and low, high, and middle represent the first, second, and third values, respectively. The meanings of other symbols are described in Example Group 1.1, and will not be repeated here.

[0219] In Example 1.6, the uplink subband of frequency domain location type three is symmetrical about the carrier frequency domain center of the carrier corresponding to the subcarrier spacing configured with the subcarrier spacing parameter of the uplink subband. This means that the center frequency of the uplink subband and the center frequency of the carrier corresponding to the subcarrier spacing configured with the subcarrier spacing parameter of the uplink subband are the same, and the parity of the number of resource blocks contained in the uplink subband and the number of resource blocks contained in the carrier corresponding to the configured subcarrier spacing is consistent.

[0220] Example 1.7 (Downlink Subband Frequency Domain Position Configuration Method)

[0221] The frequency domain location configuration parameters of the downlink subband include the first bandwidth parameter of the downlink subband, including optional parameters, which include the second bandwidth parameter of the downlink subband.

[0222] If the starting resource block position in the uplink subband's frequency domain is the same as the position of the lowest frequency resource block corresponding to the carrier space configured in the uplink subband's subcarrier spacing parameters, it indicates that it is frequency domain position type one. There is one such downlink subband. The ending resource block position in the downlink subband's frequency domain is the same as the position of the highest frequency resource block corresponding to the carrier space configured in the downlink subband's subcarrier spacing parameters. The first bandwidth parameter of the downlink subband is used to configure the bandwidth of the downlink subband. Given the ending resource block position and bandwidth of the downlink subband's frequency domain, the starting resource block position in the downlink subband's frequency domain can be determined.

[0223] If the location of the frequency domain end resource block of the uplink subband is the same as the location of the resource block with the highest frequency corresponding to the subcarrier spacing configured in the uplink subband's subcarrier spacing parameters, it indicates that it is frequency domain location type two. There is one downlink subband where the location of the frequency domain start resource block is the same as the location of the resource block with the lowest frequency corresponding to the subcarrier spacing configured in the downlink subband's subcarrier spacing parameters. The first bandwidth parameter of the downlink subband is used to configure the bandwidth of the downlink subband. Given the determined frequency domain start resource block location and bandwidth of the downlink subband, the location of the frequency domain end resource block of the downlink subband can be determined.

[0224] If the starting resource block position in the uplink subband's frequency domain is different from the position of the lowest frequency resource block corresponding to the subcarrier spacing configured in the uplink subband's subcarrier spacing parameters, and the ending resource block position in the uplink subband's frequency domain is different from the position of the highest frequency resource block corresponding to the subcarrier spacing configured in the uplink subband's subcarrier spacing parameters, then it indicates frequency domain position type three: The starting resource block position in the first downlink subband's frequency domain is the same as the position of the lowest frequency resource block corresponding to the subcarrier spacing configured in the downlink subband's subcarrier spacing parameters; the ending resource block position in the second downlink subband's frequency domain is different from the position of the highest frequency resource block corresponding to the subcarrier spacing configured in the downlink subband's subcarrier spacing parameters. The positions are the same; the first bandwidth parameter of the downlink subband is used to configure the bandwidth of the first downlink subband and the second downlink subband, and the configured bandwidth of the first downlink subband and the second downlink subband are the same; or, the first bandwidth parameter of the downlink subband is used to configure the bandwidth of the first downlink subband, and the second bandwidth parameter of the downlink subband is used to configure the bandwidth of the second downlink subband, so that the bandwidth of the first downlink subband and the second downlink subband can be configured separately, and can be different or the same; or, the second bandwidth parameter of the downlink subband is used to configure the bandwidth of the first downlink subband, and the first bandwidth parameter of the downlink subband is used to configure the bandwidth of the second downlink subband, so that the bandwidth of the first downlink subband and the second downlink subband can be configured separately, and can be different or the same.

[0225] This method only requires configuring the bandwidth information of one or two downlink subbands, which can save signaling overhead compared to configuring the bandwidth and start position of the downlink subbands at the same time.

[0226] Referring to the above description, the frequency domain location configuration signaling for the downlink subband would be, for example:

[0227] DLSubband ::= SEQUENCE {

[0228] subcarrierSpacing SubcarrierSpacing,

[0229] bandwidthOne INTEGER (1..maxNrofPhysicalResourceBlocks),

[0230] bandwidthTwo INTEGER (1..maxNrofPhysicalResourceBlocks), OPTIONAL,

[0231] }

[0232] Wherein, DLSubband represents the frequency domain position configuration signaling of the downlink subband, SubcarrierSpacing represents the subcarrier spacing parameter, bandwidthOne and bandwidthTwo represent the first bandwidth parameter and the second bandwidth parameter of the downlink subband, respectively, OPTIONAL represents optional parameters, and the meanings of other symbols are described in Example Group 1.1, and will not be repeated here.

[0233] Example 1.8 (Downlink Subband Frequency Domain Position Configuration Method)

[0234] The frequency domain location configuration parameters of the downlink subband include: the third bandwidth parameter of the downlink subband.

[0235] If the starting resource block position in the uplink subband's frequency domain is the same as the position of the lowest frequency resource block corresponding to the subcarrier spacing configured in the uplink subband's subcarrier spacing parameters, it indicates that it is frequency domain position type one. There is one such downlink subband. The ending resource block position in the downlink subband's frequency domain is the same as the position of the highest frequency resource block corresponding to the subcarrier spacing configured in the downlink subband's subcarrier spacing parameters. The third bandwidth parameter of the downlink subband is used to configure the bandwidth of the downlink subband. Given the ending resource block position and bandwidth of the downlink subband's frequency domain, the starting resource block position in the downlink subband's frequency domain can be determined.

[0236] If the location of the frequency domain end resource block of the uplink subband is the same as the location of the resource block with the highest frequency corresponding to the subcarrier spacing configured in the uplink subband's subcarrier spacing parameters, it indicates a frequency domain location type two. The downlink subband has one such type. The location of the frequency domain start resource block of the downlink subband is the same as the location of the resource block with the lowest frequency corresponding to the subcarrier spacing configured in the downlink subband's subcarrier spacing parameters. The third bandwidth parameter of the downlink subband is used to configure the bandwidth of the downlink subband. Given the determined frequency domain start resource block location and bandwidth of the downlink subband, the location of the frequency domain end resource block of the downlink subband can be determined.

The fifth bandwidth parameter of the downlink subband is used to configure the bandwidth of the downlink subband. Given the determined frequency domain end resource block location and bandwidth of the downlink subband, the location of the frequency domain start resource block of the downlink subband can be determined.

[0249] When the downlink subband's frequency domain location configuration parameters include the downlink subband's fourth bandwidth parameter, it indicates a frequency domain location type two. There is one downlink subband, and the downlink subband's frequency domain start resource block location is the same as the location of the lowest frequency resource block corresponding to the subcarrier spacing configured in the downlink subband's subcarrier spacing parameters.

[0253] subcarrierSpacing SubcarrierSpacing,

[0254] bandwidthLow INTEGER (1..maxNrofPhysicalResourceBlocks), OPTIONAL,

[0255] bandwidthHigh INTEGER (1..maxNrofPhysicalResourceBlocks), OPTIONAL,

[0256] }

[0257] In this context, bandwidthLow and bandwidthHigh represent the fourth and fifth bandwidth parameters of the downlink subband, respectively. The meanings of other symbols are described in Example 1.7 and will not be repeated here.

[0304] Configuring only the bandwidth information of the uplink subband can save signaling overhead compared to configuring both the bandwidth and start position of the uplink subband simultaneously.

[0305] In the downlink subband, if the location of the frequency domain end resource block is the same as the location of the resource block with the highest frequency corresponding to the subcarrier spacing configured in the downlink subband's subcarrier spacing parameters, it indicates that it is frequency domain location type one. Similarly, if the location of the frequency domain start resource block is the same as the location of the resource block with the lowest frequency corresponding to the subcarrier spacing configured in the uplink subband's subcarrier spacing parameters, the ninth bandwidth parameter of the uplink subband is used to configure the bandwidth of the uplink subband. Given the determined frequency domain start resource block location and bandwidth of the uplink subband, the location of the frequency domain end resource block can be determined.

Given the determined frequency-domain symmetry characteristic and bandwidth of the uplink subband about the carrier, the frequency domain position of the uplink subband can be determined. The frequency-domain symmetry of the uplink subband about the carrier corresponding to the subcarrier spacing configured by the uplink subband's subcarrier spacing parameters can be achieved by the center frequency of the uplink subband being the same as the center frequency of the carrier corresponding to the subcarrier spacing configured by the uplink subband's subcarrier spacing parameters, and the parity of the number of resource blocks contained in the uplink subband and the number of resource blocks contained in the carrier corresponding to the configured subcarrier spacing is consistent.
