[0120] Full-duplex technology enables simultaneous transmission and reception on the same frequency, effectively improving communication efficiency. Currently, full-duplex technology is in a transitional phase. At this stage, base stations possess simultaneous transmission and reception capabilities on the same frequency, while terminals do not. However, for terminals in this transitional phase, in the FDD band, the terminal still needs to ensure simultaneous transmission and reception in the time domain, while simultaneously achieving frequency division multiplexing (FDM) transmission and reception within the UL and DL bands; in the TDD band, the terminal still needs to ensure simultaneous transmission and reception in the time domain, while simultaneously achieving FDM operation of UL and DL across the entire frequency band. In other words, with technological advancements, terminals need to achieve simultaneous transmission and reception in the time domain and reduce the guard bands of DL and UL in the frequency domain. (See n1 band for an example.) Figure 1 Forecast of the progress of full-duplex technology in terminals: In the FDD band, there is at least a 30MHz guard band between DL and UL at the present stage; during the transition period of full-duplex technology, FDM transmission and reception in the existing DL and FDM transmission and reception in the existing UL will be realized; in the future full-duplex stage, simultaneous transmission and reception on the same frequency will be realized.

[0121] In the current half-duplex technology, the BWP includes the starting position of the RB relative to point A, the number of RBs occupied by the BWP, and the SCS of the BWP. In the FDD band, the point A positions of UL and DL are different; the point A position of UL is located at the edge of the DL band, and the point A position of DL is located at the edge of the UL band. The FDD terminal obtains the point A position from the frequency information corresponding to UL and DL, and then determines the BWP information for UL and DL. During the transition period of full-duplex technology, see... Figure 1 The DL point A is located at the edge of the DL band in the FDD band, while the UL point A is also located at the edge of the DL band in the FDD band. Therefore, if the current technical solution continues to use the UL point A for the DL sub-band within the original FDD band's UL band, or vice versa, it will lead to BWP position misalignment. In conclusion, the current BWP configuration is no longer suitable for the full-duplex technology transition period.

[0122] Based on this, in various embodiments of this application, the first terminal sends first information to the first base station representing the minimum frequency interval between the UL and DL frequencies supported by the first terminal. The first base station then issues a first uplink / downlink frequency range configuration to the first terminal based on the first information. Wherein, the frequency interval between UL and DL in the first uplink / downlink frequency range is greater than the minimum frequency interval represented by the first information. The uplink / downlink frequency range configuration scheme provided by the embodiments of this application can adapt to the development stage of full-duplex technology and avoid incorrect uplink / downlink frequency range configuration by the terminal during the full-duplex technology transition period.

[0123] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0124] This application provides a method for configuring uplink and downlink frequency ranges, applied to a first terminal, such as... Figure 2 As shown, the method includes:

[0125] Step 201: Send first information to the first base station; the first information represents the minimum frequency interval between the UL frequency and DL frequency supported by the first terminal.

[0126] Step 202: Receive the configuration of the first uplink and downlink frequency range sent by the first base station based on the first information.

[0127] Wherein, the frequency interval between UL and DL in the first uplink and downlink frequency range is greater than the minimum frequency interval represented by the first information.

[0128] Here, the first terminal reports the minimum frequency interval between the UL frequency and DL frequency supported by the first terminal to the first base station. When configuring the uplink and downlink frequency range for the first terminal, the first base station uses the minimum frequency interval between the UL frequency and DL frequency supported by the first terminal as a reference. The frequency interval between UL and DL in the configured first uplink and downlink frequency range is greater than the minimum frequency interval between UL and DL supported by the first terminal.

[0129] The minimum frequency interval includes at least one of the following:

[0130] Minimum frequency spacing between UL's BWP and DL's BWP;

[0131] The minimum frequency interval between the UL sub-band and the DL sub-band.

[0132] In practical applications, the minimum frequency interval can be presented in the first information through one or more different representations. In one embodiment, the first information includes at least one of the following:

[0133] First index;

[0134] First frequency range;

[0135] Second frequency range.

[0136] The first index represents the index corresponding to the minimum frequency interval supported by the first terminal among at least two set minimum frequency intervals. For example, multiple minimum frequency intervals are defined by default, and the order in which these multiple minimum frequency intervals are arranged is defined. In this way, each minimum frequency interval will be assigned an index according to the corresponding arrangement order, and the terminal reports the index corresponding to the minimum frequency interval between the supported UL frequency and DL frequency through the first information.

[0137] The first frequency range represents the frequency range corresponding to the minimum frequency interval supported by the first terminal among at least two set minimum frequency intervals. For example, multiple minimum frequency intervals are defined by default. The terminal determines the corresponding frequency interval from among the multiple default minimum frequency intervals based on the minimum frequency interval between the supported UL frequency and DL frequency, and reports the frequency range corresponding to the determined frequency interval, that is, the specific frequency interval value, through the first information.

[0138] The second frequency range characterizes the frequency range of the minimum frequency interval supported by the first terminal. Here, the terminal reports the specific frequency interval value corresponding to the minimum frequency interval between the supported UL frequency and DL frequency through the first information.

[0139] In one embodiment, the minimum frequency interval represents at least one of the following:

[0140] Minimum frequency spacing corresponding to the FDD operating frequency band;

[0141] The minimum frequency interval corresponding to the FDD working carrier;

[0142] The minimum frequency interval corresponding to the UL band of the FDD operating frequency band;

[0143] The minimum frequency spacing corresponding to the DL band in the FDD operating frequency band.

[0144] In other words, the minimum frequency interval represented by the first information can be for each FDD operating frequency band, or it can be for the UL band of each FDD operating frequency band, or it can be for the DL band of each FDD operating frequency band, or it can be for each FDD operating carrier.

[0145] In one embodiment, the first information is characterized by bandwidth and / or the number of RBs.

[0146] In other words, the minimum frequency interval can be characterized in the first piece of information by bandwidth and / or the number of RBs. For example, the minimum frequency interval can be characterized in kHz, or by the number of RB blocks.

[0147] Since the first information is represented by the number of RBs, the SCS also needs to be specified. Therefore, the first information also includes the first SCS.

[0148] The first SCS includes at least one of the following:

[0149] The corresponding frequency range has a predefined SCS. For example, the SCS for the FR1 band is 15kHz, and the SCS for the FR2 band is 60kHz.

[0150] The network side configures the SCS for the corresponding frequency range; that is, the network side configures the corresponding SCS for different frequency bands.

[0151] The first terminal supports the SCS in the corresponding frequency range, that is, the terminal reports the SCS it supports for different frequency bands.

[0152] Correspondingly, this application embodiment also provides a method for configuring uplink and downlink frequency ranges, applied to a first base station, such as... Figure 3 As shown, the method includes:

[0153] Step 301: Receive first information sent by the first terminal; the first information represents the minimum frequency interval between the UL frequency and DL frequency supported by the first terminal.

[0154] Step 302: Based on the first information, send the configuration of the first uplink and downlink frequency range to the first terminal.

[0155] Wherein, the frequency interval between UL and DL in the first uplink and downlink frequency range is greater than the minimum frequency interval represented by the first information.

[0156] Here, the first terminal reports the minimum frequency interval between the UL frequency and DL frequency supported by the first terminal to the first base station. When configuring the uplink and downlink frequency range for the first terminal, the first base station uses the minimum frequency interval between the UL frequency and DL frequency supported by the first terminal as a reference. The frequency interval between UL and DL in the configured first uplink and downlink frequency range is greater than the minimum frequency interval between UL and DL supported by the first terminal.

[0157] The minimum frequency interval includes at least one of the following:

[0158] Minimum frequency spacing between UL's BWP and DL's BWP;

[0159] The minimum frequency interval between the UL sub-band and the DL sub-band.

[0160] In practical applications, the minimum frequency interval can be presented in the first information through one or more different representations. In one embodiment, the first information includes at least one of the following:

[0161] First index;

[0162] First frequency range;

[0163] Second frequency range.

[0164] The first index represents the index corresponding to the minimum frequency interval supported by the first terminal among at least two set minimum frequency intervals. For example, multiple minimum frequency intervals are defined by default, and the order in which these multiple minimum frequency intervals are arranged is defined. In this way, each minimum frequency interval will be assigned an index according to the corresponding arrangement order, and the terminal reports the index corresponding to the minimum frequency interval between the supported UL frequency and DL frequency through the first information.

[0165] The first frequency range represents the frequency range corresponding to the minimum frequency interval supported by the first terminal among at least two set minimum frequency intervals. For example, multiple minimum frequency intervals are defined by default. The terminal determines the corresponding frequency interval from among the multiple default minimum frequency intervals based on the minimum frequency interval between the supported UL frequency and DL frequency, and reports the frequency range corresponding to the determined frequency interval, that is, the specific frequency interval value, through the first information.

[0166] The second frequency range characterizes the frequency range of the minimum frequency interval supported by the first terminal. Here, the terminal reports the specific frequency interval value corresponding to the minimum frequency interval between the supported UL frequency and DL frequency through the first information.

[0167] In practical applications, multiple default minimum frequency intervals can be configured in advance based on the minimum frequency interval between the UL frequency and DL frequency supported by various terminals.

[0168] In one embodiment, the minimum frequency interval represents at least one of the following:

[0169] Minimum frequency spacing corresponding to the FDD operating frequency band;

[0170] The minimum frequency interval corresponding to the FDD working carrier;

[0171] The minimum frequency interval corresponding to the UL band of the FDD operating frequency band;

[0172] The minimum frequency spacing corresponding to the DL band in the FDD operating frequency band.

[0173] In other words, the minimum frequency interval represented by the first information can be for each FDD operating frequency band, or it can be for the UL band of each FDD operating frequency band, or it can be for the DL band of each FDD operating frequency band, or it can be for each FDD operating carrier.

[0174] In one embodiment, the first information is characterized by bandwidth and / or the number of RBs.

[0175] In one embodiment, the first information is characterized by the number of RBs; the first information also includes a first SCS.

[0176] The first SCS includes at least one of the following:

[0177] The corresponding frequency range is predefined by the SCS;

[0178] The network side configures the SCS for the corresponding frequency range;

[0179] The first terminal supports SCS for the corresponding frequency range.

[0180] Here, after receiving the first information sent by the first terminal, the first base station determines the terminal capability of the first terminal based on the minimum frequency interval between the UL and DL frequencies supported by the first terminal, as represented by the first information. Based on the terminal capability, the first base station configures a dedicated uplink and downlink frequency range for the first terminal, such as a BWP or sub-band. This configured uplink and downlink frequency range ensures that the frequency interval between the DL and UL frequencies configured for the first terminal is greater than the minimum frequency interval between the UL and DL frequencies supported by the first terminal. Based on this, the network side can configure dedicated uplink and downlink frequency ranges for terminals with different capabilities. Especially during the transition to full-duplex technology, because terminals have different capabilities in supporting the minimum frequency interval (gap) between the DL and UL frequencies, high-capability terminals can support smaller gaps, while low-capability terminals can only support larger gaps. Therefore, configuring dedicated uplink and downlink frequency ranges for terminals based on their capabilities can prevent misalignment of the BWP positions for terminals with different capabilities.

[0181] This application also provides a BWP configuration method for a second base station, such as... Figure 4 As shown, the method includes:

[0182] Step 401: Send the configuration of the second BWP to the second terminal.

[0183] The configuration of the second BWP includes second information; the second information is used to indicate the location of point A.

[0184] Here, the network side specifies the relative frequency start point in the BWP configuration, i.e., the location of point A.

[0185] The second information includes at least one of the following:

[0186] The frequency of point A;

[0187] The first bit; the first bit represents that point A corresponds to the UL configuration of the original FDD band or the DL configuration of the original FDD band.

[0188] Here, the second information can be represented as the frequency of point A. For example, in practical applications, the frequency of point A can be represented by ARFCN, which is the absolute frequency number. The second information can also be represented as a bit. By specifying different bit values, it can be indicated that point A corresponds to the UL configuration of the original FDD band, or that point A corresponds to the DL configuration of the original FDD band.

[0189] In addition, in practical applications, the first bit can also be left as a default value. When the first bit takes a default value, it represents one of the following information by default:

[0190] The value of point A is the same as that of point A in the UL configuration of the original FDD band. That is, the default position of point A is the edge position of the UL band relative to the original FDD band. At this time, the distinction between UL band and DL point A is no longer made.

[0191] The value of point A is the same as that of point A in the DL configuration of the original FDD band. That is, the default position of point A is relative to the edge of the DL band of the original FDD band. At this time, the distinction between UL band and DL point A is no longer made.

[0192] The value of point A is the same as the point A included in the operating frequency band configuration of the second BWP, meaning that the default position of point A is the minimum frequency domain edge position relative to the operating frequency band of the currently configured BWP. In this case, assume that the FDD frequency band is renamed in a full-duplex scenario, and that the uplink frequency band number is different from the downlink frequency band number.

[0193] Correspondingly, this application also provides a BWP configuration method, applied to a second terminal, such as... Figure 5 As shown, the method includes:

[0194] Step 501: Receive the configuration of the second BWP sent by the second base station.

[0195] The configuration of the second BWP includes second information; the second information is used to indicate the location of point A.

[0196] Here, the network side specifies the relative frequency starting point, i.e., the position of point A, in the BWP configuration. In this way, for terminals in the transition period of full-duplex technology, UL point A or DL ​​point A will no longer be used, thus avoiding the occurrence of BWP position confusion.

[0197] In one embodiment, the second information includes at least one of the following:

[0198] The frequency of point A;

[0199] The first bit; the first bit represents that point A corresponds to the UL configuration of the original FDD band or the DL configuration of the original FDD band.

[0200] Here, the second information can be represented as the frequency of point A. For example, in practical applications, the frequency of point A can be represented by ARFCN, which is the absolute frequency number. The second information can also be represented as a bit. By specifying different bit values, it can be indicated that point A corresponds to the UL configuration of the original FDD band, or that point A corresponds to the DL configuration of the original FDD band.

[0201] In addition, in practical applications, the first bit can also be left as a default value. When the first bit takes a default value, it represents one of the following information by default:

[0202] The value of point A is the same as that of point A in the UL configuration of the original FDD band. That is, the default position of point A is the edge position of the UL band relative to the original FDD band. At this time, the distinction between UL band and DL point A is no longer made.

[0203] The value of point A is the same as that of point A in the DL configuration of the original FDD band. That is, the default position of point A is relative to the edge of the DL band of the original FDD band. At this time, the distinction between DL band and UL point A is no longer made.

[0204] The value of point A is the same as the point A included in the operating frequency band configuration of the second BWP, meaning that the default position of point A is the minimum frequency domain edge position relative to the operating frequency band of the currently configured BWP. In this case, assume that the FDD frequency band is renamed in a full-duplex scenario, and that the uplink frequency band number is different from the downlink frequency band number.
