[0120] FIG2A is an interactive diagram illustrating a capability indication method according to an embodiment of the present disclosure. As shown in FIG2A , an embodiment of the present disclosure relates to a capability indication method, the method comprising:

[0121] Step S2101: The terminal sends first information to the network device.

[0122] In some embodiments, the network device receives the first information sent by the terminal. In some embodiments, the terminal sends the first information. In some embodiments, the network device receives the first information.

[0123] In some embodiments, the first information is used to indicate that the terminal has full-duplex capability. In some embodiments, full-duplex capability means that the terminal supports simultaneous uplink transmission and downlink reception. In some embodiments, full-duplex capability can also be understood as the terminal being able to perform both uplink transmission and downlink reception at the same time. In some embodiments, uplink transmission refers to the terminal sending data to the network device. In some embodiments, downlink reception refers to the terminal receiving data sent by the network device.

[0124] In some embodiments, the present disclosure does not limit the name of the full-duplex capability. Examples include full-duplex mode, duplex capability, etc. In some embodiments, the present disclosure does not limit the name of the first information. Examples include capability information, indication information, and reporting information.

[0125] In the embodiment of the present disclosure, the terminal may report its own full-duplex capability through the first information, and the subsequent network device may perform data transmission with the terminal based on the full-duplex capability.

[0126] In some embodiments, as shown in FIG2B , within a certain period of time, the full-duplex capability of the terminal can both receive data through a downlink and send data through an uplink.

[0127] In some embodiments, the full-duplex capability includes either SBFD (Sub Band Full Duplexer) or Full Duplexer.

[0128] In some embodiments, full-duplex capability includes multiple types, and the first information includes a first value, the first value being used to indicate the type of full-duplex capability, and the first value corresponds to the type of full-duplex capability. In the disclosed embodiment, each type of full-duplex capability corresponds to a numerical value, and when reporting the type of full-duplex capability, the terminal can indicate the corresponding type of full-duplex capability by reporting a specific numerical value.

[0129] In some embodiments, the type of full-duplex capability is indicated by one bit, for example, 0 is used to indicate the type of full-duplex capability, and 1 is used to indicate the second type of full-duplex capability. In some embodiments, the type of full-duplex capability is indicated by two bits, for example, 00 is used to indicate the type of full-duplex capability, 01 is used to indicate the second type of full-duplex capability, 10 is used to indicate the third type of full-duplex capability, and 11 is used to indicate the fourth type of full-duplex capability.

[0130] The following uses one bit indicating the type of full-duplex capability as an example. For example, 0 is used to indicate that the full-duplex capability is SBFD, and 1 is used to indicate that the full-duplex capability is Full Duplexer. If the bit included in the first information is 0, it means that the full-duplex capability reported by the terminal is SBFD.

[0131] It should be noted that the above-mentioned method of indicating full-duplex capability by numerical value is merely an example. In another embodiment, the type of full-duplex capability may be indicated by other methods. In some embodiments, different parameters are carried in the first information to indicate different types of full-duplex capability. Optionally, if the first information carries a first parameter, the first parameter is used to indicate that the full-duplex capability is SBFD. If the first information carries a second parameter, the second parameter is used to indicate that the full-duplex capability is Full Duplexer. In another embodiment, the full-duplex capability may also be indicated by other methods, which are not limited in the embodiments of the present disclosure.

[0132] In some embodiments, the first information is further used to indicate a frequency band interval. In some embodiments, the frequency band interval refers to the interval between the frequency band corresponding to uplink transmission and the frequency band corresponding to downlink reception. In some embodiments, the frequency band interval refers to the interval between the uplink frequency band and the downlink frequency band. In some embodiments, the uplink frequency band is used for uplink transmission. In some embodiments, the downlink frequency band is used for downlink reception. In some embodiments, the frequency band interval refers to the interval between the frequency band corresponding to the uplink and the frequency band corresponding to the downlink. For example, referring to Figure 2B, the frequency band interval is the interval between the uplink and downlink.

[0133] In some embodiments, the frequency band interval is at least one of RB, subcarrier, or frequency. Optionally, if the frequency band interval is RB, it indicates that the frequency band interval is measured in units of RB. For example, the frequency band interval is 2RB, 4RB, or another value. Optionally, if the frequency band interval is subcarrier, it indicates that the frequency band interval is measured in units of subcarrier. For example, the frequency band interval is 2 subcarriers, 4 subcarriers, or another value. Optionally, if the frequency band interval is frequency band, it indicates that the frequency band interval is measured in units of frequency. For example, the frequency band interval is 10 Hz, 20 Hz, or another value. In some embodiments, the first information includes a magnitude relationship between the frequency band interval and an interval threshold. In some embodiments, if the first information includes a magnitude relationship between the frequency band interval and the interval threshold, if the frequency band interval is less than the interval threshold, it indicates that the frequency band interval is low, that is, the frequency band interval is less than the interval threshold. If the frequency band interval is greater than the interval threshold, it indicates that the frequency band interval is high, that is, the frequency band interval is greater than the interval threshold. In some embodiments, the interval threshold is agreed upon by a communication protocol, or configured by a network device, or determined by the terminal itself, or determined in other ways, and is not limited in the embodiments of the present disclosure.

[0134] In some embodiments, the first information includes a second value, and the second value corresponds to a frequency band interval. In the embodiment of the present disclosure, the first information indicates the corresponding frequency band interval by carrying a numerical value. In some embodiments, the frequency band interval is indicated by two bits, for example, 00 is used to indicate a frequency band interval of 10 Hz, 01 is used to indicate a frequency band interval of 15 Hz, 10 is used to indicate a frequency band interval of 20 Hz, and 11 is used to indicate a frequency band interval of 25 Hz.

[0135] It should be noted that, in the embodiment of the present disclosure, when the terminal indicates that the full-duplex capability is SBFD, the first information can also be used to indicate the frequency band interval. Alternatively, it can also be understood that when the full-duplex capability indicated by the terminal is SBFD, the first information also includes the frequency band interval.

[0136] It should be noted that the above embodiment uses the example of the first information indicating the frequency band interval by including the second value. In another embodiment, the first information directly indicates the corresponding frequency band interval by including the frequency band interval. In some embodiments, if the first information includes 2RB, it indicates that the frequency band interval is 2RB; if the first information includes 10 subcarriers, it indicates that the frequency band interval is 10 subcarriers; if the first information includes 20Hz, it indicates that the frequency band interval is 20Hz.

[0137] In some embodiments, the first information is used to indicate power information, and the power information is used to indicate the transmit power of the terminal for uplink transmission. In the embodiments of the present disclosure, when the terminal reports its own capabilities, it also reports its own transmit power for uplink transmission.

[0138] In some embodiments, the terminal not only indicates the frequency band interval through the first information, but also indicates power information through the first information, and different power information corresponds to different frequency band intervals.

[0139] Optionally, if the frequency band interval is RB as the granularity, refer to Table 1, frequency band intervals with different numbers of RBs correspond to different power information.

[0140] Table 1

[0141] It should be noted that in the embodiment of the present disclosure, when the terminal indicates that the full-duplex capability is SBFD, the first information can also be used to indicate power information. Alternatively, it can also be understood that when the full-duplex capability indicated by the terminal is SBFD, the first information also includes power information.

[0142] It should be noted that the embodiment of the present disclosure is the first information sent when certain conditions are met.

[0143] In some embodiments, the terminal's uplink transmit power is less than a power threshold, and the terminal sends the first information to the network device. In some embodiments, the power threshold is agreed upon by the communication protocol, configured by the network device, or configured in other ways, and is not limited in the embodiments of the present disclosure. In the embodiments of the present disclosure, if the terminal's uplink transmit power is less than the power threshold, it indicates that the terminal's uplink transmission has little interference with downlink reception. In this case, the terminal can enable full-duplex capability, and therefore the terminal sends the first information. For example, the power threshold is -10dBm, -20dBm, or other values, and is not limited in the embodiments of the present disclosure.

[0144] In some embodiments, the terminal is in a low-mobility state and sends the first information to the network device. In some embodiments, the low-mobility state means that the terminal has not moved a long distance within a certain period of time, or it can also be understood as the terminal's slow movement speed, or it can also be understood as the terminal's position has not changed significantly within a certain period of time. In the embodiments of the present disclosure, if the terminal is in a low-mobility state, it means that the terminal will not be significantly interfered with when performing uplink transmission or downlink reception, and therefore the terminal can report the first information.

[0145] In some embodiments, the uplink transmission power of the terminal is less than a power threshold and the terminal is in a low mobility state, and the first information is sent to the network device.

[0146] In some embodiments, the method further includes: determining that the terminal is in a low mobility state when the terminal's mobility rate is less than a rate threshold. In some embodiments, the rate threshold is agreed upon by a communication protocol, configured by a network device, or configured in other ways, which is not limited in the embodiments of the present disclosure.

[0147] Step S2102: The network device sends second information to the terminal.

[0148] In some embodiments, the terminal receives the second information sent by the network device. In some embodiments, the network device sends the second information. In some embodiments, the terminal receives the second information.

[0149] In some embodiments, the second information is used to configure the terminal to communicate based on full-duplex capability. In the disclosed embodiment, after the terminal sends the first information to the network device, the network device can determine that the terminal has full-duplex capability, and thus the network device can configure the terminal to communicate based on full-duplex capability through the second information.

[0150] In some embodiments, the present disclosure does not limit the name of the second information, which may be, for example, configuration information, instruction information, etc.

[0151] Step S2103: The terminal sends uplink data to the network device.
