Detailed ways

Full-duplex technology can realize simultaneous transmission and reception at the same frequency, effectively improving communication efficiency. At present, the development of full-duplex technology is in a transition period. At this stage, the base station has the capability of transmitting and receiving at the same frequency at the same time, but the terminal does not yet have the capability of transmitting and receiving at the same frequency. However, for terminals in the transition period of full-duplex technology, in the FDD frequency band, the terminal still needs to ensure simultaneous transmission and reception in the time domain, and at the same time realize frequency division multiplexing (FDM, Frequency division multiplexing) transmission and reception in UL and DL Work; in the time-division duplex (TDD, Time-Division Duplex) frequency band, the terminal still needs to ensure simultaneous transmission and reception in the time domain, and at the same time realize the FDM work of UL and DL in the entire frequency range. That is to say, as the technology improves, the terminal needs to implement simultaneous transmission and reception in the time domain and the reduction of DL and UL guard bands in the frequency domain. Taking the n1 frequency band as an example, refer to Figure 1 to predict the progress of terminal full-duplex technology: in the FDD frequency band, there is at least a 30MHz guard band between DL and UL at this stage; In the FDM form of transmission and reception, as well as in the existing UL FDM transmission and reception; in the future full-duplex stage, and finally realize simultaneous transmission and reception at the same frequency.

In the current half-duplex technology, the BWP includes the starting position of the RB relative to the point A position, the number of RBs occupied by the BWP, and the SCS of the BWP. In the FDD frequency 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 frequency band, and the point A position of DL is located at the edge of the UL frequency band. The FDD terminal obtains the position of point A from the frequency information corresponding to UL and DL, and on this basis, specifies the BWP information of UL and DL. In the full-duplex technology transition period, see Figure 1, the point A of DL is located at the edge of the DL frequency band of the FDD frequency band, and the point A of the UL is located at the edge of the DL frequency band of the FDD frequency band. In this way, according to the current technical solution, the UL point A position is still used for the DL subband in the UL frequency band of the original FDD frequency band, or the DL point A is still used for the UL subband in the DL frequency band of the original FDD frequency band position, it will cause the BWP position to be confused. To sum up, the current BWP configuration scheme is no longer suitable for the full-duplex technology transition period.

Based on this, in various embodiments of the present application, the first terminal sends to the first base station first information representing the minimum frequency interval between the UL frequency and the DL frequency supported by the first terminal, and the first base station based on the The first information is the configuration of the first uplink and downlink frequency range issued by the first terminal; wherein, the frequency interval between UL and DL in the first uplink and downlink frequency range is greater than the minimum frequency represented by the first information interval. The configuration scheme of the uplink and downlink frequency ranges provided by the embodiments of the present application can adapt to the development stage of the full-duplex technology, and avoid terminal configuration of wrong uplink and downlink frequency ranges during the transition period of the full-duplex technology.

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.

Here, the first terminal reports to the first base station the minimum frequency interval between the UL frequency supported by the first terminal and the DL frequency, and when the first base station configures the uplink and downlink frequency ranges for the first terminal, the UL frequency The minimum frequency interval between the DL frequency and the DL frequency is used as a reference, and the configured frequency interval between the UL and the DL in the first uplink and downlink frequency range is greater than the minimum frequency interval between the UL and the DL supported by the first terminal.

That is to say, the minimum frequency interval represented by the first information may be for each FDD operating frequency band, or may be for each FDD operating frequency band of the UL frequency band, or may be for each FDD operating frequency band of the DL frequency band, Or it may be for each FDD working carrier.

In an embodiment, the first information is characterized by bandwidth and/or the number of RBs.

That is to say, in the first information, the minimum frequency interval may be characterized by the bandwidth and/or the number of RBs. For example, the minimum frequency interval is represented by kHz, or the minimum frequency interval is represented by the number of RB blocks.

When the first information is characterized by the number of RBs, it is also necessary to specify the SCS, therefore, the first information also includes the first SCS.

Wherein, the first SCS includes at least one of the following:

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

Step 302: Based on the first information, issue a configuration of a first uplink and downlink frequency range to the first terminal.

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.

Here, the first terminal reports to the first base station the minimum frequency interval between the UL frequency supported by the first terminal and the DL frequency, and when the first base station configures the uplink and downlink frequency ranges for the first terminal, the UL frequency The minimum frequency interval between the DL frequency and the DL frequency is used as a reference, and the configured frequency interval between the UL and the DL in the first uplink and downlink frequency range is greater than the minimum frequency interval between the UL and the DL supported by the first terminal.

Wherein, the minimum frequency interval includes at least one of the following:

Minimum frequency separation between UL BWP and DL BWP;

Minimum frequency separation between UL sub-bands and DL sub-bands.

In practical applications, the minimum frequency interval may be presented in one or more different representation forms in the first information. In an embodiment, the first information includes at least one of the following:

first index;

a first frequency range;

Second frequency range.

Wherein, the first index represents an 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 arrangement order of these various minimum frequency intervals 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 supported UL frequency and The index corresponding to the minimum frequency separation between DL frequencies.

The first frequency range represents a frequency range corresponding to the minimum frequency interval supported by the first terminal among at least two set minimum frequency intervals. For example, a variety of minimum frequency intervals are defined by default, and the terminal determines the corresponding frequency interval among the various minimum frequency intervals defined by default according to the minimum frequency interval between the supported UL frequency and the DL frequency, and corresponds the determined frequency interval to The frequency range, that is, the specific frequency interval value is reported through the first information.

The second frequency range represents 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 the DL frequency through the first information.

In actual application, various minimum frequency intervals defined by default may be configured in advance according to the minimum frequency intervals between UL frequencies and DL frequencies supported by various types of terminals.

In an embodiment, the minimum frequency interval is characterized by at least one of the following:

The minimum frequency interval corresponding to the FDD working frequency band;

The minimum frequency interval corresponding to the FDD working carrier;

The minimum frequency interval corresponding to the UL frequency band of the FDD working frequency band;

That is to say, the minimum frequency interval represented by the first information may be for each FDD operating frequency band, or may be for each FDD operating frequency band of the UL frequency band, or may be for each FDD operating frequency band of the DL frequency band, Or it may be for each FDD working carrier.

Wherein, the first SCS includes at least one of the following:

Corresponding frequency range predefined SCS;

Here, after receiving the first information sent by the first terminal, the first base station determines the terminal capability of the first terminal according to the minimum frequency interval between the UL frequency and the DL frequency supported by the first terminal represented by the first information, And based on the terminal capabilities of the first terminal, configure a dedicated uplink and downlink frequency range for the first terminal, such as BWP or sub-frequency bands, so that the configured uplink and downlink frequency range can ensure that the frequency interval between the DL and UL configured for the first terminal is greater than The minimum frequency interval between the UL frequency and the DL frequency supported by the first terminal. Based on this, the network side can configure dedicated uplink and downlink frequency ranges for terminals with different terminal capabilities. Especially in the transition period of full-duplex technology, due to the different support capabilities of terminals between the minimum frequency interval (gap) between DL frequency and UL frequency, for high-capability terminals, they have the ability to support smaller gaps, while for low-capability terminals , can only support a larger gap. Therefore, here, the network side configures the terminal-specific uplink and downlink frequency ranges according to the terminal capabilities, which can avoid the confusion of the BWP positions of terminals with different capabilities.

Wherein, the second information includes at least one of the following:

The frequency of point A;

The first bit; the first bit indicates that point A corresponds to the UL configuration of the original FDD frequency band or corresponds to the DL configuration of the original FDD frequency band.

For example, in practical application, the frequency point of point A can be represented by ARFCN, that is, the absolute frequency point number. The second information can also be characterized as bits, and by using different bit values for the bits, it can be represented that point A is a UL configuration corresponding to the original FDD frequency band, or that point A is a DL configuration corresponding to the original FDD frequency band.

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

The value of point A is the same as point A in the UL configuration of the original FDD frequency band, that is, the default position of point A is the edge position of the UL frequency band relative to the original FDD frequency band, and no distinction is made between the UL frequency band and DL point A at this time;

The value of point A is the same as point A in the DL configuration of the original FDD frequency band, that is, the default position of point A is the edge position of the DL frequency band relative to the original FDD frequency band. At this time, the UL frequency band and DL point A are no longer distinguished;

The value of point A is the same as the point A contained in the configuration of the working frequency band where the second BWP is located, that is, the default position of point A is the minimum frequency domain edge position relative to the working frequency band where the currently configured BWP is located. At this point, assume that the FDD frequency band is renamed to a frequency band number in a full-duplex scenario, and the uplink frequency band number is different from the downlink frequency band number.

Correspondingly, the embodiment of the present application also provides a BWP configuration method, which is applied to the second terminal, as shown in FIG. 5 , the method includes:

The first bit; the first bit indicates that point A corresponds to the UL configuration of the original FDD frequency band or corresponds to the DL configuration of the original FDD frequency band.

Here, the second information can be characterized as the frequency point of point A. For example, in practical application, the frequency point of point A can be represented by ARFCN, that is, the absolute frequency point number. The second information can also be characterized as bits, and by using different bit values for the bits, it can be represented that point A is a UL configuration corresponding to the original FDD frequency band, or that point A is a DL configuration corresponding to the original FDD frequency band.

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

The value of point A is the same as point A in the UL configuration of the original FDD frequency band, that is, the default position of point A is the edge position of the UL frequency band relative to the original FDD frequency band, and no distinction is made between the UL frequency band and DL point A at this time;

The value of point A is the same as the point A contained in the configuration of the working frequency band where the second BWP is located, that is, the default position of point A is the minimum frequency domain edge position relative to the working frequency band where the currently configured BWP is located. At this point, assume that the FDD frequency band is renamed to a frequency band number in a full-duplex scenario, and the uplink frequency band number is different from the downlink frequency band number.
