Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a resource configuration method and a communication device. Background Art

[0002] In a traditional time division duplex (TDD) system, the entire frequency domain resources of a time unit in the TDD system are used for downlink transmission or for uplink transmission. For example, taking the time unit as a time slot, when a time slot is a downlink time slot, it cannot be used to send uplink data, and when a time slot is an uplink time slot, it cannot be used to send downlink data. In addition, the downlink time slot accounts for a large proportion, resulting in insufficient uplink resources and an increase in uplink service scheduling delay. In order to overcome the delay problem caused by the TDD system, one possible way is to introduce subband full duplex (SBFD). SBFD refers to inserting an uplink subband for uplink transmission in the frequency domain of a downlink time unit or a flexible time unit. How to configure resources after the introduction of SBFD is an urgent problem to be solved. Summary of the Invention

[0003] The embodiments of the present application provide a resource configuration method and a communication device, which can realize flexible configuration of frequency domain resources of at least one of an uplink sub-band, a downlink sub-band, and a guard band after the introduction of SBFD.

[0004] In a first aspect, an embodiment of the present application provides a resource configuration method, wherein the method can be performed by a terminal device or by a component of the terminal device (such as a processor, a chip, or a chip system), and the method includes:

[0005] Receive configuration information, where the configuration information includes at least one of frequency domain information of an uplink subband, frequency domain information of a downlink subband, and frequency domain information of a guard band; the configuration information is used to determine a frequency domain position of at least one of the uplink subband, the downlink subband, and the guard band.

[0006] Implementing the method of the first aspect, after introducing SBFD, the network device can configure at least one of the frequency domain information of the uplink subband, the frequency domain information of the downlink subband, and the frequency domain information of the guard band through configuration information. Due to the positional relationship between the uplink subband, the downlink subband, and the guard band, the terminal device can determine the frequency domain position of at least one of the uplink subband, the downlink subband, or the guard band through the configuration information, thereby realizing flexible configuration of the frequency domain resources of the uplink subband, the downlink subband, and the guard band.

[0007] In a possible implementation, the downlink subband includes a first downlink subband and / or a second downlink subband; the maximum frequency of the first downlink subband is less than the minimum frequency of the uplink subband; the minimum frequency of the second downlink subband is greater than the maximum frequency of the uplink subband; the frequency domain information of the downlink subband includes frequency domain information of the first downlink subband and / or frequency domain information of the second downlink subband;

[0008] The guard band includes a first guard band and / or a second guard band; the minimum frequency of the first guard band is greater than the maximum frequency of the first downlink sub-band, and the maximum frequency of the first guard band is less than the minimum frequency of the uplink sub-band; the minimum frequency of the second guard band is greater than the maximum frequency of the uplink sub-band, and the maximum frequency of the second guard band is less than the minimum frequency of the second downlink sub-band; the frequency domain information of the guard band includes the frequency domain information of the first guard band and / or the frequency domain information of the second guard band.

[0009] In this embodiment, after the introduction of SBFD, there can be multiple possible positional relationships between the uplink subband, downlink subband and guard band, so that the frequency domain positions of the uplink subband, downlink subband and guard band under various positional relationships can be flexibly configured.

[0010] In a possible implementation, the configuration information includes frequency domain information of the uplink subband, the frequency domain information of the uplink subband includes a first frequency domain offset and broadband information of the uplink subband, the first frequency domain offset is a frequency domain offset of a starting frequency domain unit of the uplink subband relative to a reference frequency domain position, and the broadband information of the uplink subband is used to determine a first number of frequency domain units included in the uplink subband;

[0011] The starting frequency domain unit of the uplink subband is determined by the first frequency domain offset;

[0012] The frequency domain position of the uplink subband is a frequency domain resource consisting of the first number of consecutive frequency domain units starting from the starting frequency domain unit of the uplink subband.

[0013] By implementing this method, the frequency domain position of the uplink subband can be determined by configuring the frequency domain offset of the uplink subband and the broadband information of the uplink subband, thereby facilitating the terminal device to accurately determine the frequency domain position of the uplink subband.

[0014] In a possible implementation, the downlink subband includes the first downlink subband, the configuration information includes frequency domain information of the first downlink subband, the frequency domain information of the first downlink subband includes broadband information of the first downlink subband, and the broadband information of the first downlink subband is used to determine a second number of frequency domain units included in the first downlink subband;

[0016] The frequency domain position of the first downlink sub-band is a frequency domain resource consisting of the second number of consecutive frequency domain units starting from the starting frequency domain unit of the first downlink sub-band.

[0017] By implementing this method, the starting frequency domain unit of the downlink carrier can be used as the starting frequency domain unit of the first downlink subband. Therefore, the configuration information does not need to configure the frequency domain offset of the first downlink subband. The configuration information only needs to configure the frequency domain information of the first downlink subband, thereby saving configuration information overhead.

[0018] In a possible implementation, the guard band includes the first guard band,

[0019] The starting frequency domain unit of the first guard band is the frequency domain unit after the ending frequency domain unit of the first downlink sub-band; the ending frequency domain unit of the first guard band is the frequency domain unit before the starting frequency domain unit of the uplink sub-band;

[0020] The frequency domain position of the first guard band is a frequency domain resource consisting of at least one continuous frequency domain unit starting from a start frequency domain unit of the first guard band to an end frequency domain unit of the first guard band.

[0021] By implementing this method, when the configuration information configures the first downlink subband and the uplink subband, the frequency domain position of the first guard band can be derived based on the frequency domain position of the first downlink subband and the frequency domain position of the uplink subband, thereby saving configuration information overhead.

[0024] The end frequency domain unit of the first guard band is the frequency domain unit before the start frequency domain unit of the uplink subband;

[0025] The frequency domain position of the first guard band is a frequency domain resource consisting of at least one continuous frequency domain unit starting from a start frequency domain unit of the first guard band to an end frequency domain unit of the first guard band.

[0026] When implementing this method, the configuration information configures the frequency domain offset of the first guard band, and there is no need to configure broadband information. The end frequency domain unit of the first guard band is derived through the starting frequency domain unit of the uplink subband, so that the frequency domain position of the first guard band can be accurately obtained and the configuration information overhead can be saved.

[0027] In a possible implementation, the guard band includes the first guard band, the configuration information includes broadband information of the first guard band, and the broadband information of the first guard band is used to determine a third number of frequency domain units included in the first guard band;

[0030] When implementing this method, the configuration information configures the broadband information of the first guard band, and there is no need to configure the frequency domain offset of the first guard band. The end frequency domain unit of the first guard band is derived by the starting frequency domain unit of the uplink sub-band, thereby accurately obtaining the frequency domain position of the first guard band and saving configuration information overhead.

[0035] By implementing this method, when the configuration information configures the first guard band and uplink subband, the frequency domain position of the first downlink subband can be derived.

[0129] In an embodiment of the present application, the network device may send configuration information to the terminal device, where the configuration information includes at least one of the frequency domain information of the uplink sub-band, the frequency domain information of the downlink sub-band, and the frequency domain information of the guard band, thereby facilitating the terminal device to determine the frequency domain position of at least one of the uplink sub-band, the downlink sub-band, and the guard band according to the configuration information.

[0130] The following explains some of the terms involved in the embodiments of the present application to facilitate understanding by those skilled in the art.

[0131] 1. SBFD

[0132] SBFD refers to inserting a continuous frequency domain resource for uplink transmission into the frequency domain of a downlink time unit or flexible time unit in a TDD system. The frequency domain of this downlink time unit or flexible time unit also includes frequency domain resources for downlink transmission, which can be called a downlink subband. By introducing SBFD, a base station can perform both uplink and downlink transmissions within a time unit. A time unit can be a time domain unit such as a time slot or a symbol. To reduce interference between uplink and downlink transmissions, a guard band can be included between the uplink and downlink subbands.

[0133] The following combination Figure 2 For example, Figure 2 In the frequency domain of time unit 2, time unit 3 and time unit 4, an uplink subband for uplink transmission is inserted, and the uplink subband is marked with "U". The frequency domain resources of time unit 2, time unit 3 and time unit 4 also include a downlink subband for downlink transmission, and the downlink subband is marked with "D". A continuous frequency domain resource between the uplink subband and the downlink subband is called a guard band, such as Figure 2 As shown in .

[0134] exist Figure 2 In FIG, time unit 1 is a downlink time unit, and all frequency domain resources of time unit 1 are frequency domain resources used for downlink transmission. Time unit 5 is an uplink time unit, and all frequency domain resources of time unit 5 are frequency domain resources used for uplink transmission.

[0135] 2. Frequency domain unit

[0136] The frequency domain unit in the embodiment of the present application refers to a basic unit in the frequency domain. For example, the frequency domain unit can be a physical resource block (PRB), a common resource block (CRB) or a resource block (RB).

[0137] In the embodiment of the present application, the numbering of the frequency domain units may be sequentially increasing from low to high frequency. For example, taking CRB as an example, the numbering may start from 0, and the CRBs may be sequentially numbered as CRB0, CRB1, CRB2, CRB3, CRB4, and so on. Alternatively, CRB may be replaced by PRB.

[0138] The previous frequency domain unit described in the embodiment of the present application refers to the frequency domain unit corresponding to the number minus 1, and the next frequency domain unit refers to the frequency domain unit corresponding to the number plus 1. For example, the previous frequency domain unit of CRB2 is CRB1, and the next frequency domain unit of CRB2 is CRB3.

[0139] In the embodiment of the present application, the frequency domain unit can be replaced by CRB, PRB or RB, etc.

[0140] 3. CRB and Point A

[0141] For subcarrier spacing configuration μ, CRBs are numbered in ascending order of frequency in the frequency domain, starting from 0 and numbering upwards. The center frequency of subcarrier 0 of CRB0 for subcarrier spacing configuration μ corresponds to the location of Point A. For subcarrier spacing configuration μ, determining the location of Point A also determines the numbering of each CRB. Point A locations for different subcarrier spacing configurations overlap.

[0142] 4. PRB

[0143] In the frequency domain, regardless of the subcarrier spacing μ, 12 consecutive subcarriers can be defined as a PRB. A larger subcarrier spacing μ corresponds to a larger actual bandwidth. The PRB is the basic unit for allocating resources in the frequency domain. Within a bandwidth part (BWP), PRBs are also numbered in ascending order of frequency, starting from 0 and numbering upwards.

[0144] The resource configuration method in the embodiments of the present application is described in detail below. It should be noted that the various technical solutions (or embodiments) of the present application can be implemented independently or in combination based on certain internal connections. This application is not limited to this. Moreover, the various terms and definitions between the various embodiments can be referenced to each other. In each embodiment of the present application, different implementation methods can also be implemented in combination or independently.

[0145] Please refer to Figure 3 , is a flow chart of a resource configuration method provided in an embodiment of the present application, such as Figure 3 As shown, the resource configuration method of this embodiment includes but is not limited to the following steps:

[0146] 301. The network device sends configuration information, which includes at least one of the frequency domain information of an uplink subband, the frequency domain information of a downlink subband, and the frequency domain information of a guard band. Correspondingly, the terminal device receives the configuration information.

[0147] 302. The terminal device determines a frequency domain position of at least one of an uplink subband, a downlink subband, and a guard band according to configuration information.

[0148] Among them, step 302 is an optional step. In some implementations, step 302 may not be performed. For example, the network device sends configuration information to the terminal device for configuring at least one of the frequency domain information of the uplink subband, the frequency domain information of the downlink subband, and the frequency domain information of the protection band, and the terminal device does not need to determine the frequency domain position.

[0149] In some embodiments, the downlink sub-band may include a first downlink sub-band and / or a second downlink sub-band, wherein the maximum frequency of the first downlink sub-band is less than the minimum frequency of the uplink sub-band, and the minimum frequency of the second downlink sub-band is greater than the maximum frequency of the uplink sub-band.

[0150] The following combination Figure 4 An example is given to illustrate the sub-band distribution, such as Figure 4 As shown in (A), the first downlink subband is identified by "D1" and the second downlink subband is identified by "D2". If the downlink subband includes the first downlink subband and the second downlink subband, the position relationship between the first downlink subband, the second downlink subband and the uplink subband is as follows: Figure 4 As shown in (A), for the convenience of description, Figure 4 The subband distribution shown in (A) is referred to as DUD. If the downlink subband only includes the first downlink subband, the position relationship between the first downlink subband and the uplink subband is as follows: Figure 4 As shown in (B), for the convenience of description, Figure 4 The subband distribution shown in (B) is referred to as DU. If the downlink subband only includes the second downlink subband, the position relationship between the second downlink subband and the uplink subband is as follows: Figure 4 As shown in (C), for the convenience of description, Figure 4 The subband distribution shown in (C) is referred to as UD. It can be understood that the first downlink subband and the second downlink subband are only used to distinguish different downlink subbands, and the first downlink subband and the second downlink subband can also be referred to as downlink subbands.

[0151] In some embodiments, the guard band may include a first guard band and / or a second guard band, wherein the minimum frequency of the first guard band is greater than the maximum frequency of the first downlink sub-band, and the maximum frequency of the first guard band is less than the minimum frequency of the uplink sub-band. The minimum frequency of the second guard band is less than the maximum frequency of the uplink sub-band, and the maximum frequency of the second guard band is less than the minimum frequency of the second downlink sub-band. Figure 4 Give an example, such as Figure 4 As shown in (A), the first guard band is marked as "guard band 1" and the second guard band is marked as "guard band 2". If the guard band includes the first guard band and the second guard band, the position relationship between the first guard band, the second guard band, the uplink sub-band, the first downlink sub-band, and the second downlink sub-band is as follows: Figure 4If the guard band only includes the first guard band, the positional relationship between the first guard band, the uplink sub-band, and the first downlink sub-band is as follows: Figure 4 If the guard band only includes the second guard band, the positional relationship between the second guard band, the uplink sub-band, and the second downlink sub-band is as follows: Figure 4 It is understood that the first protection band and the second protection band are only used to distinguish different protection bands, and the first protection band and the second protection band may also be referred to as protection bands.

[0152] For example, the network device may configure the subband distribution to be one of {DUD, DU, UD} through high-layer signaling. For example, the network device may not configure the subband distribution and obtain the subband distribution from the configuration information.

[0153] In this embodiment of the present application, the configuration information may include at least one of the frequency domain information of the uplink subband, the frequency domain information of the downlink subband, and the frequency domain information of the guard band. The terminal device may determine the frequency domain position of at least one of the uplink subband, the downlink subband, or the guard band based on the configuration information. The following examples illustrate the content of the configuration information in combination with different subband distribution situations:

[0154] In a first possible implementation, the subband distribution is DU, the downlink subband includes the first downlink subband, the guard band includes the first guard band, and the positional relationship among the uplink subband, the first downlink subband, and the first guard band is as follows: Figure 4 As shown in (B), the following example illustrates the contents of the configuration information:

[0155] In mode 1, the configuration information may include frequency domain information of an uplink subband and frequency domain information of a first downlink subband.

[0156] The frequency domain information of the uplink subband may include a first frequency domain offset and broadband information of the uplink subband. The first frequency domain offset is the frequency domain offset of the starting frequency domain unit of the uplink subband relative to the reference frequency domain position, and the frequency domain offset may be counted in frequency domain units.

[0157] Exemplarily, for all subcarrier spacings, the reference frequency domain position may be the frequency domain position corresponding to Point A, that is, the first frequency domain offset is the frequency domain offset of the starting frequency domain unit of the uplink subband relative to Point A, such as Figure 5a The offset 1 is the frequency domain offset of the starting frequency domain unit of the uplink subband corresponding to Point A. Exemplarily, the reference frequency domain position may be the frequency domain starting position of the downlink carrier, that is, the first frequency domain offset is the frequency domain offset of the starting frequency domain unit of the uplink subband relative to the frequency domain starting position of the downlink carrier, such as Figure 5aThe offset 2 is the frequency domain offset of the starting frequency domain unit of the uplink subband relative to the frequency domain starting position of the downlink carrier. Exemplarily, the reference frequency domain position can be the frequency domain starting position of the uplink carrier, that is, the first frequency domain offset is the frequency domain offset of the starting frequency domain unit of the uplink subband relative to the frequency domain starting position of the uplink carrier, such as Figure 5a The medium offset 3 is the frequency domain offset of the starting frequency domain unit of the uplink subband relative to the frequency domain starting position of the uplink carrier.

[0158] The broadband information of the uplink subband is used to determine the first number of frequency domain units included in the uplink subband. In the embodiment of the present application, the broadband information can be replaced by length or bandwidth. Figure 5a Chinese N RB Shown is a first number of frequency domain units included in an uplink subband.

[0159] In the embodiment of the present application, the starting frequency domain unit of the uplink subband can be determined according to the first frequency domain offset, and the first number N of frequency domain units included in the uplink subband can be determined according to the broadband information of the uplink subband. RB The frequency domain position of the uplink subband is a frequency domain resource consisting of a first number of consecutive frequency domain units starting from the starting frequency domain unit of the uplink subband. Figure 5a The U mark in the figure is a schematic diagram of the frequency domain position of the uplink subband.

[0160] The frequency domain information of the first downlink subband may include broadband information of the first downlink subband, and the broadband information of the first downlink subband is used to determine the second number of frequency domain units included in the first downlink subband, such as Figure 5a N in RB,D1 The second number of frequency domain units included in the first downlink sub-band is the second number of frequency domain units included in the first downlink sub-band, and the frequency domain information of the first downlink sub-band may not include the frequency domain offset of the first downlink sub-band.

[0161] The starting frequency domain unit of the first downlink subband may be the starting frequency domain unit of the downlink carrier where the first downlink subband is located, that is, the frequency domain offset of the first downlink subband may be the same as the frequency domain offset of the downlink carrier. Figure 5a As shown, the starting frequency domain unit of the first downlink subband is the same as the frequency domain starting position of the downlink carrier.

[0162] In the embodiment of the present application, frequency domain resources consisting of a second number of consecutive frequency domain units starting from the starting frequency domain unit of the first downlink sub-band are determined as the frequency domain position of the first downlink sub-band.

[0163] The frequency domain position of the first guard band can be implicitly obtained based on the frequency domain positions of the above first downlink sub-band and uplink sub-band. Specifically, the starting frequency domain unit of the first guard band is the frequency domain unit after the ending frequency domain unit of the first downlink sub-band, that is, the starting frequency domain unit of the first guard band is numbered by 1 as the ending frequency domain unit of the first downlink sub-band. The ending frequency domain unit of the first guard band is the frequency domain unit before the starting frequency domain unit of the uplink sub-band, that is, the ending frequency domain unit of the first guard band is numbered by 1 as the starting frequency domain unit of the uplink sub-band. The frequency domain position of the first guard band is a frequency domain resource consisting of at least one continuous frequency domain unit starting from the starting frequency domain unit of the first guard band to the ending frequency domain unit of the first guard band. For example, Figure 5a As shown in FIG, the position of the guard band 1 is a schematic diagram of the frequency domain position of the first guard band.

[0164] In the above method 1, the frequency domain information of the uplink subband includes the frequency domain offset and broadband information, and the frequency domain information of the first downlink subband includes broadband information but does not include the frequency domain offset. In some implementations, the frequency domain information of the first downlink subband may include the frequency domain offset and broadband information, the frequency domain information of the uplink subband may include broadband information but does not include the frequency domain offset, and the ending frequency domain unit of the uplink subband may be the same as the ending frequency domain unit of the uplink carrier.

[0165] In mode 2, the configuration information may include frequency domain information of the uplink subband and frequency domain information of the first guard band. The content included in the frequency domain information of the uplink subband can refer to the description of mode 1 of the first possible implementation mode, and will not be repeated here. The following two cases are used as examples to describe the content included in the frequency domain information of the first guard band:

[0166] In case 1, the frequency domain information of the first guard band includes a second frequency domain offset, which is the frequency domain offset of the starting frequency domain unit of the first guard band relative to the reference frequency domain position. In case 1, the frequency domain information of the first guard band may not include broadband information of the first guard band.

[0167] Exemplarily, the reference frequency domain position may be the frequency domain position corresponding to Point A, that is, the second frequency domain offset is the frequency domain offset of the starting frequency domain unit of the first guard band corresponding to Point A, such as Figure 5b The offset 1 is the frequency domain offset of the starting frequency domain unit of the first guard band corresponding to Point A. Exemplarily, the reference frequency domain position may be the frequency domain starting position of the downlink carrier, that is, the second frequency domain offset is the frequency domain offset of the starting frequency domain unit of the first guard band relative to the frequency domain starting position of the downlink carrier, such as Figure 5bThe offset 2 is the frequency domain offset of the starting frequency domain unit of the first guard band relative to the frequency domain starting position of the downlink carrier. Exemplarily, the reference frequency domain position can be the frequency domain starting position of the uplink carrier, that is, the second frequency domain offset is the frequency domain offset of the starting frequency domain unit of the first guard band relative to the frequency domain starting position of the uplink carrier, such as Figure 5b The medium offset 3 is the frequency domain offset of the starting frequency domain unit of the first guard band relative to the frequency domain starting position of the uplink carrier.

[0168] In the embodiment of the present application, the starting frequency domain unit of the first guard band can be determined according to the above-mentioned second frequency domain offset, and the ending frequency domain unit of the first guard band can be the frequency domain unit before the starting frequency domain unit of the uplink sub-band, that is, the number of the ending frequency domain unit of the first guard band is the number of the starting frequency domain unit of the uplink sub-band minus 1. The frequency domain position of the first guard band is a frequency domain resource consisting of at least one continuous frequency domain unit starting from the starting frequency domain unit of the first guard band to the ending frequency domain unit of the first guard band. Figure 5b The guard band 1 shown is a schematic diagram of the frequency domain position of the first guard band.

[0169] Case 2: The frequency domain information of the first guard band includes broadband information of the first guard band, and the broadband information of the first guard band is used to determine the third number of frequency domain units included in the first guard band, such as Figure 5c N in RB,G1 is the third number of frequency domain units included in the first guard band. In case 2, the frequency domain information of the first guard band may not include the frequency domain offset of the first guard band.

[0170] In case 2, the frequency domain unit before the starting frequency domain unit of the uplink subband is used as the ending frequency domain unit of the first guard band, that is, the ending frequency domain unit of the first guard band is numbered by the starting frequency domain unit of the uplink subband minus 1.

[0171] The frequency domain position of the first guard band can be determined based on the end frequency domain unit of the first guard band and the third number of frequency domain units included in the first guard band, that is, the frequency domain position of the first guard band is the frequency domain resource composed of the third number of continuous frequency domain units up to the end frequency domain unit of the first guard band. Exemplarily, the number of the end frequency domain unit minus the value of the third number and then adding 1 is the number of the starting frequency domain unit of the first guard band. For example, the end frequency domain unit of the first guard band is RB6, and the third number of frequency domain units included in the first guard band is 3, then the starting frequency domain unit of the first guard band is RB4, and the frequency domain resources composed of RB4, RB5 and RB6 are used as the frequency domain position of the first guard band.

[0172] In method 2, the frequency domain position of the first downlink subband can be implicitly obtained based on the frequency domain positions of the above first guard band and uplink subband. Specifically, the starting frequency domain unit of the first downlink subband is the starting frequency domain unit of the downlink carrier where the first downlink subband is located, that is, the frequency domain offset of the first downlink subband is the same as the frequency domain offset of the downlink carrier. The ending frequency domain unit of the first downlink subband is the previous frequency domain unit of the starting frequency domain unit of the first guard band, that is, the ending frequency domain number of the first downlink subband is the number of the starting frequency domain unit of the first guard band minus 1. The frequency domain resources composed of at least one continuous frequency domain unit starting from the starting frequency domain unit of the first downlink subband to the ending frequency domain unit of the first downlink subband are used as the frequency domain position of the first downlink subband. As shown in FIG. Figure 5b and Figure 5c As shown, D1 identifies the frequency domain position of the first downlink sub-band.

[0173] Mode 3: The configuration information may include frequency domain information of the first guard band.

[0174] The frequency domain information of the first guard band may include a second frequency domain offset of the first guard band and broadband information of the first guard band, where the second frequency domain offset is a frequency domain offset of a starting frequency domain unit of the first guard band relative to a reference frequency domain position. The broadband information of the first guard band is used to determine a third number of frequency domain units protected by the first guard band.

[0175] For the relevant description of the second frequency domain offset, please refer to the description of Case 1 of Method 2 of the first possible implementation method. For the relevant description of the broadband information of the first guard band, please refer to the description of Case 2 of Method 2 of the first possible implementation method. In the embodiment of the present application, the starting frequency domain unit of the first guard band can be determined based on the above-mentioned second frequency domain offset, and the third number of frequency domain units included in the first guard band can be determined based on the broadband information of the first guard band. The frequency domain position of the first guard band is a frequency domain resource consisting of a third number of consecutive frequency domain units starting from the starting frequency domain unit of the first guard band.

[0176] The frequency domain position of the first downlink sub-band and the frequency domain position of the uplink sub-band can be implicitly obtained according to the frequency domain position of the first guard band.

[0177] The starting frequency domain unit of the uplink subband is the frequency domain unit following the ending frequency domain unit of the first guard band, that is, the starting frequency domain unit of the uplink subband is numbered by 1, which is the ending frequency domain unit number of the first guard band.

[0178] As an example, the end frequency domain unit of the uplink subband is the end frequency domain unit of the uplink carrier where the uplink subband is located, that is, the frequency domain end position of the uplink subband is the same as the frequency domain end position of the uplink carrier, for example, Figure 5a 、 Figure 5b 、 Figure 5cThe frequency domain end position of the uplink subband and the frequency domain end position of the uplink carrier.

[0179] As another example, if a second guard band is included between the uplink subband and the end frequency domain unit of the uplink carrier, the end frequency domain unit of the uplink subband is the frequency domain unit before the start frequency domain unit of the second guard band, that is, the end frequency domain unit of the uplink subband is numbered by 1 less than the start frequency domain unit of the second guard band.

[0180] A frequency domain resource consisting of at least one frequency domain unit from a start frequency domain unit to an end frequency domain unit of an uplink subband is referred to as a frequency domain position of an uplink subband.

[0181] The starting frequency domain unit of the first downlink subband is the starting frequency domain unit of the downlink carrier, that is, the starting frequency domain position of the first downlink subband is the same as the starting frequency domain position of the downlink carrier. It can also be understood that the frequency domain offset of the first downlink subband is the same as the frequency domain offset of the downlink carrier. The ending frequency domain unit of the first downlink subband is the frequency domain unit before the starting frequency domain unit of the first guard band, that is, the ending frequency domain unit of the first downlink subband is numbered by the starting frequency domain unit number of the first guard band minus 1.

[0182] A frequency domain resource consisting of at least one continuous frequency domain unit from a start frequency domain unit to an end frequency domain unit of the first downlink subband is used as the frequency domain position of the first downlink subband.

[0183] In mode 4, the configuration information may include frequency domain information of an uplink subband, frequency domain information of a first downlink subband, and frequency domain information of a first guard band.

[0184] The frequency domain information of an uplink subband may include the frequency domain offset of the uplink subband and the broadband information of the uplink subband. The frequency domain offset of the uplink subband is the frequency domain offset of the starting frequency domain unit of the uplink subband relative to the reference frequency domain position. The broadband information of the uplink subband is used to determine the number of frequency domain units included in the uplink subband. The frequency domain position of the uplink subband may be determined based on the frequency domain offset and the broadband information of the uplink subband.

[0185] The frequency domain information of the first downlink subband may include a frequency domain offset for the first downlink subband and broadband information for the first downlink subband. The frequency domain offset for the first downlink subband is the frequency domain offset of the starting frequency domain unit of the first downlink subband relative to a reference frequency domain position. The broadband information of the first downlink subband is used to determine the number of frequency domain units included in the first downlink subband. The frequency domain position of the first downlink subband may be determined based on the frequency domain offset and broadband information of the first downlink subband.

[0186] The frequency domain information of the first guard band may include the frequency domain offset of the first guard band and the broadband information of the first guard band. The frequency domain offset of the first guard band is the frequency domain offset of the starting frequency domain unit of the first guard band relative to the reference frequency domain position. The broadband information of the first guard band is used to determine the number of frequency domain units included in the first guard band. The frequency domain position of the first guard band can be determined based on the frequency domain offset of the first guard band and the broadband information of the first guard band.

[0187] In a second possible implementation, the subband distribution is UD, that is, the downlink subband includes the second downlink subband, the guard band includes the second guard band, and the positional relationship among the uplink subband, the second downlink subband and the second guard band is as follows: Figure 4 As shown in (C), the following example illustrates the contents of the configuration information:

[0188] In mode 1, the configuration information may include frequency domain information of the uplink subband and frequency domain information of the second downlink subband. The frequency domain information of the uplink subband may include a first frequency domain offset and broadband information of the uplink subband. For details, please refer to the description of mode 1 of the first possible implementation method, which will not be repeated here. The following describes the content included in the frequency domain information of the second downlink subband using two examples:

[0189] In case 1, the frequency domain information of the second downlink subband includes a third frequency domain offset, which is the frequency domain offset of the starting frequency domain unit of the second downlink subband relative to the reference frequency domain position. In case 1, the frequency domain information of the second downlink subband may not include broadband information of the second downlink subband.

[0190] Exemplarily, the reference frequency domain position may be the frequency domain position corresponding to Point A, that is, the third frequency domain offset is the frequency domain offset of the starting frequency domain unit of the second downlink subband corresponding to Point A, such as Figure 5d The offset 1 is the frequency domain offset of the starting frequency domain unit of the second downlink subband corresponding to Point A. Exemplarily, the reference frequency domain position may be the frequency domain starting position of the downlink carrier, that is, the third frequency domain offset is the frequency domain offset of the starting frequency domain unit of the second downlink subband relative to the frequency domain starting position of the downlink carrier, such as Figure 5d The offset 2 is the frequency domain offset of the starting frequency domain unit of the second downlink subband relative to the frequency domain starting position of the downlink carrier. Exemplarily, the reference frequency domain position may be the frequency domain starting position of the uplink carrier, that is, the third frequency domain offset is the frequency domain offset of the starting frequency domain unit of the second downlink subband relative to the frequency domain starting position of the uplink carrier, such as Figure 5d The medium offset 3 is the frequency domain offset of the starting frequency domain unit of the second downlink subband relative to the frequency domain starting position of the uplink carrier.

[0191] In an embodiment of the present application, the starting frequency domain unit of the second downlink subband can be determined according to the above-mentioned third frequency domain offset, and the ending frequency domain unit of the second downlink subband can be the ending frequency domain unit of the downlink carrier where the second downlink subband is located, that is, the frequency domain end position of the second downlink subband is the same as the frequency domain end position of the downlink carrier.

[0192] The frequency domain position of the second downlink subband is a frequency domain resource consisting of at least one continuous frequency domain unit starting from the start frequency domain unit of the second downlink subband to the end frequency domain unit of the second downlink subband. Figure 5d As shown in FIG, what is marked by D2 is a schematic diagram of the frequency domain position of the second downlink sub-band.

[0193] Case 2: The frequency domain information of the second downlink subband includes broadband information of the second downlink subband. The broadband information of the second downlink subband is used to determine the fourth number of frequency domain units included in the second downlink subband, such as Figure 5e In, N RB,D2 is the fourth number of frequency domain units included in the second downlink subband. In case 2, the frequency domain information of the second downlink subband may not include the frequency domain offset of the second downlink subband.

[0194] In case 2, the end frequency domain unit of the downlink carrier where the second downlink subband is located is used as the end frequency domain unit of the second downlink subband, that is, the frequency domain end position of the second downlink subband is the same as the frequency domain end position of the downlink carrier.

[0195] The frequency domain position of the second downlink subband can be determined according to the end frequency domain unit of the second downlink subband and the fourth number of frequency domain units included in the second downlink subband, that is, the frequency domain position of the second downlink subband is the frequency domain resource consisting of the fourth number of continuous frequency domain units up to the end frequency domain unit of the second downlink subband, such as Figure 5e As shown, the frequency domain position diagram of the second downlink sub-band identified by D2 is shown. Exemplarily, the number of the ending frequency domain unit minus the value of the fourth quantity and then added by 1 is the number of the starting frequency domain unit of the second downlink sub-band. For example, the ending frequency domain unit of the second downlink sub-band is RB6, and the third number of frequency domain units included in the second downlink sub-band is 3, then the starting frequency domain unit of the second downlink sub-band is RB4, and the frequency domain resources composed of RB4, RB5 and RB6 are used as the frequency domain position of the second downlink sub-band.

[0196] Furthermore, the frequency domain position of the second guard band can be implicitly obtained based on the frequency domain positions of the second downlink sub-band and the uplink sub-band. Specifically, the starting frequency domain unit of the second guard band is the frequency domain unit after the ending frequency domain unit of the uplink sub-band; that is, the starting frequency domain unit of the second guard band is numbered by 1 to the ending frequency domain unit of the uplink sub-band. The ending frequency domain unit of the second guard band is the frequency domain unit before the starting frequency domain unit of the second downlink sub-band; that is, the ending frequency domain unit of the second guard band is numbered by 1 to the starting frequency domain unit of the second downlink sub-band. The frequency domain position of the second guard band is a frequency domain resource consisting of at least one continuous frequency domain unit from the starting frequency domain unit of the second guard band to the ending frequency domain unit of the second guard band. As Figure 5c As shown, guard band 2 is a schematic diagram of the frequency domain position of the second guard band.

In this manner, the frequency domain information of the second guard band may not include the frequency domain offset of the second guard band.

[0199] The frequency domain unit following the ending frequency domain unit of the uplink subband is used as the starting frequency domain unit of the second guard band. That is, the starting frequency domain unit of the second guard band is numbered by the ending frequency domain unit of the uplink subband plus 1. The frequency domain position of the second guard band is the frequency domain resource consisting of the fifth consecutive frequency domain units starting from the starting frequency domain unit of the second guard band.

The ending frequency domain unit of the second downlink subband is the ending frequency domain unit of the downlink carrier containing the second downlink subband, i.e., the ending frequency domain position of the second downlink subband is the same as the ending frequency domain position of the downlink carrier.
