Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a full-duplex communication processing method, apparatus, terminal, and network-side equipment. Background Technology

[0002] Compared to previous mobile communication systems, future mobile communication systems need to adapt to more diverse scenarios and service requirements, such as Enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communications (URLLC), and Massive Machine-Type Communications (mMTC). These scenarios place demands on systems with high reliability, low latency, high bandwidth, and wide coverage. Among these, configuring full-duplex operation can significantly improve the latency and coverage performance of Time-Division Duplex (TDD) systems.

[0003] For example, configuring full-duplex operation for network-side devices allows them to simultaneously transmit downlink signals or channels and receive uplink signals or channels within a single time unit (e.g., a timeslot or symbol). This enhances coverage, reduces transmission latency, and improves resource utilization efficiency.

[0004] Furthermore, the terminal can be configured for full-duplex operation, enabling it to simultaneously receive downlink signals or channels and transmit uplink signals or channels within a single time unit. This allows for maintaining high uplink (UL) and downlink (DL) performance (e.g., throughput) while achieving coverage gain and reduced latency.

[0005] However, when the terminal is transmitting and receiving simultaneously, there is self-interference between the UL channel or signal and the DL channel or signal. Currently, the network-side equipment cannot know about the self-interference situation of the terminal transmitting and receiving simultaneously, which affects the downlink reception of the terminal. Summary of the Invention

[0032] The aforementioned first target feedback information is used to indicate whether the terminal can decode the first object. When the self-interference level of the terminal's simultaneous transmission and reception is large, the terminal will be unable to decode the first object, while when the self-interference level is small, the terminal can decode the first object. Therefore, whether the terminal can decode the first object can indicate the different self-interference levels of the terminal's simultaneous transmission and reception.

[0033] Therefore, in this embodiment, the terminal can use the first target feedback information received downlink to report to the network-side device whether it can decode the first object, thereby indicating the degree of self-interference of simultaneous transmission and reception by the terminal. Thus, in this embodiment, the network-side device can use the first target feedback information of the terminal to learn about the self-interference situation of simultaneous transmission and reception, providing a basis for the network-side device to schedule uplink and downlink transmissions, and improving the downlink reception performance of the terminal.

[0059] To facilitate understanding of the full-duplex communication processing method in the embodiments of this application, the following related technologies are now introduced.

[0060] I. Regarding Subband Non-overlapping Full-Duplex

[0061] Sub-band Full Duplex (SBFD) refers to a carrier whose different frequency bands can be used for downlink and uplink transmission respectively. In this way, during the downlink time slot, some sub-bands can transmit uplink data, thus SBFD can improve transmission delay and enhance coverage.

[0062] For example, for a downlink time slot (DL slot) (which can be configured by cell-level configuration (tdd-UL-DL-ConfigurationCommon) or UE-specific configuration (tdd-UL-DL-ConfigurationDedicated), the network side configures the downlink bandwidth portion (DL BWP) for the UE, for example... Figure 2 In slot 1; for uplink slots (UL slots), the network configures uplink bandwidth portion (UL BWP) for the UE, for example... Figure 3 Time slot 4 in the middle.

[0063] For full-duplex scenarios, for example, it can be... Figure 2 Time slot 2 (network side configured with DLBWP and UL sub-band); can also be... Figure 3 Time slot 5 (network side configured with DL BWP and UL subband).

[0064] In addition, for SBFD operations, an SBFD subband consists of a single resource block (RB) or a continuous set of RBs with the same transmission direction.

[0065] In addition, the time unit used by the network side for SBFD operations can be called the SBFD time unit (e.g., slot or symbol).

[0066] II. Full-duplex technology

[0067] like Figure 4 As shown, in Rel-15, network-side devices (e.g., base stations) and UEs can only transmit or receive within a time unit (e.g., a time slot);

[0068] In Rel-18, full-duplex mode is supported on the network side, meaning that network devices can send and receive simultaneously, while terminals can only use half-duplex mode, meaning that they can only send or receive in a single time unit.

[0069] Based on the above, full-duplex mode can also be configured on the terminal side, meaning that network devices can send and receive simultaneously; terminals can also send and receive simultaneously.

[0070] Therefore, the types of time units used for transmission can be as follows: Figure 5 As shown, it includes the downlink (DL) time unit, the GNB FD (i.e., network-side full-duplex) time unit, the UE FD (i.e., terminal-side full-duplex) time unit, and the uplink (UL) time unit.

[0071] The full-duplex communication processing method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0072] Firstly, embodiments of this application provide a full-duplex communication processing method, such as... Figure 6 As shown, the method may include the following step 601:

[0073] Step 601: The terminal receives the first object in the first time unit.

[0074] The first time unit includes: a first subband supporting the reception of the first object and a second subband supporting the transmission of the second object, wherein the first object includes at least one of a downlink channel and a downlink signal, and the second object includes at least one of an uplink channel and an uplink signal.

[0075] Therefore, it can be seen that the first time unit supports simultaneous transmission and reception, that is, the terminal uses full-duplex within the first time unit.

[0076] Step 602: The terminal sends first target feedback information for the first object.

[0077] The first target feedback information is used to indicate whether the terminal can decode the first object.

[0078] Optionally, the first target feedback information includes Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK).

[0079] In addition, the following two full-duplex modes exist in the embodiments of this application:

[0080] Network-side full-duplex mode: that is, the network side application is full-duplex, and the terminal side application is half-duplex.

[0081] Terminal full-duplex mode: This means that both network-side applications and terminal-side applications are full-duplex.

[0082] Here, the UE side uses half-duplex, meaning that within one time unit, the terminal can only perform uplink transmission or downlink reception; the UE side uses full-duplex, meaning that within one time unit, the terminal can perform both uplink transmission and downlink reception simultaneously.

[0083] Furthermore, the aforementioned first object pertains to downlink, while the aforementioned first target feedback information pertains to uplink. When the terminal uses full-duplex operation, it can simultaneously receive downlink data and transmit uplink data within a single time unit. In this case, the uplink transmission by the terminal can cause self-interference to the downlink reception. However, in this embodiment, the terminal can use the first target feedback information received by the first object to indicate whether it can decode the first object. Whether or not the first object can be decoded is related to the degree of self-interference in the simultaneous transmission and reception. Thus, in this embodiment, the terminal can use the first target feedback information received by the downlink to indicate to the network-side device whether it can decode the first object (i.e., if the terminal can decode the first object, it indicates that the degree of self-interference is small, the terminal's receiver is not saturated, and therefore the first object can be decoded; if the terminal cannot decode the first object, it indicates that the degree of self-interference is large, the terminal's receiver is saturated, and therefore the first object cannot be decoded). Consequently, the network-side device can obtain the degree of self-interference in the simultaneous transmission and reception of the terminal (i.e., obtain the terminal's self-interference cancellation capability information).

[0084] As can be seen from steps 601 to 602 above, in this embodiment, the terminal can use the first target feedback information received downlink to report to the network-side device whether it can decode the first object, thereby indicating the degree of self-interference of simultaneous transmission and reception by the terminal. Therefore, in this embodiment, the network-side device can use the first target feedback information of the first object received by the terminal to know the self-interference situation of simultaneous transmission and reception by the terminal, providing a basis for the network-side device to schedule uplink and downlink transmissions, and improving the downlink reception performance of the terminal.

[0085] Optionally, the method further includes:

[0086] The terminal receives the first transmission information;

[0087] The first transmission information is determined based on the first target feedback information, and the first transmission information includes at least one of the uplink transmission parameters and downlink transmission parameters allowed in the full-duplex mode on the terminal side. That is, the first transmission information includes: the limit value (e.g., maximum or minimum value) of the uplink transmission allowed in the full-duplex mode on the terminal side, the limit value (e.g., maximum or minimum value) of the downlink transmission parameters, and at least one of the parameter pair set (e.g., the set of beam pairs) of the uplink and downlink transmission parameters determined based on the first target feedback information.

[0088] Therefore, after receiving the first target feedback information sent by the terminal, the network-side device determines the aforementioned first transmission information of the terminal based on the first target feedback information and configures it for the terminal.

[0089] In addition, the first target feedback information is used to indicate whether the terminal can decode the first object. In this way, the network-side device can know the degree of self-interference of the terminal, and adjust at least one of the uplink transmission parameters and downlink transmission parameters allowed by the terminal in full-duplex mode on the terminal side to obtain the aforementioned first transmission information, so as to reduce the self-interference of uplink transmission on downlink reception when the terminal transmits and receives simultaneously.

[0090] Optionally, the downlink channel includes at least one of the following:

[0091] Physical Downlink Shared Channel (PDSCH);

[0092] Downlink control channel (e.g., a channel carrying downlink control information (DCI)).

[0093] Therefore, it can be seen that the terminal can receive PDSCH and send PDSCH feedback information. Here, the PDSCH feedback information is used to indicate whether the terminal can decode PDSCH. In this way, after the network-side device receives the PDSCH feedback information, it can determine the terminal's first transmission information based on the PDSCH feedback information, so that the terminal's uplink transmission reduces self-interference with the PDSCH reception.

[0094] Similarly, the terminal can receive the downlink control channel and send feedback information of the downlink control channel. Here, the feedback information of the downlink control channel is used to indicate whether the terminal can decode the downlink control channel. In this way, after the network-side device receives the feedback information of the downlink control channel, it can determine the terminal's first transmission information based on the feedback information of the downlink control channel, so that the uplink transmission of the terminal reduces self-interference with the reception of the downlink control channel.

[0095] Furthermore, simultaneous receiving and transmitting by a communication device can cause self-interference. To ensure transmission in the direction of interference, the communication device needs to have self-interference cancellation capabilities. For example, a guard band (GB) is typically reserved between UL and DL transmissions to achieve frequency isolation and reduce self-interference. Since the self-interference cancellation capability of the terminal is usually weaker than that of the network-side equipment, the guard band required for simultaneous receiving and transmitting by the terminal is larger than that required for simultaneous receiving and transmitting by the network side; that is, more Physical Resource Blocks (PRBs) are needed as guard bands.

[0096] Optionally, in this embodiment of the application, the width of the first protection band can be set to be greater than the width of the second protection band; wherein, the first protection band is a reserved protection band between the uplink subband and the downlink subband in the full-duplex mode on the network side; and the second protection band is a reserved protection band between the uplink subband and the downlink subband in the full-duplex mode on the terminal side.

[0097] like Figure 7 As shown, in full-duplex mode on the network side, the network-side device configures time-frequency resources for the uplink subband (UL SB) and downlink subband (DL SB), and can further configure time-frequency resources for the guard band (GB). In UL SB, the network-side device receives the UL channel or signal from the served terminal. In DL SB, the network-side device transmits the DL channel or signal for the served terminal. In this case, the DL transmission of the network-side device will cause self-interference to the UL reception.

[0098] In full-duplex mode on the terminal side, the network-side equipment configures time-frequency resources for UL SB and DL SB for the terminal. Furthermore, it can also configure time-frequency resources for GB. In this case, the terminal's UL transmission will cause self-interference to DL reception.

[0099] Among these, the network-side full-duplex mode can enhance coverage, reduce transmission latency, and improve resource utilization efficiency. The terminal-side full-duplex mode can improve DL (UL) throughput while achieving the above gains.

[0100] It should also be noted that different terminals may have different capabilities, so the amount of GB that needs to be reserved may vary.

[0101] Optionally, the first target feedback information includes at least one of the following A-1 to A-8:

[0102] Item A-1: ​​First feedback information, indicating that the first object was correctly decoded (i.e., the first object was correctly received);

[0103] Item A-2: Second feedback information, indicating that the terminal failed to decode the first object; here, the terminal's failure to decode the first object can be considered as the terminal's receiver not being saturated (or blocked), and the decoding failure being caused by excessive interference or poor channel conditions. In this case, there may be a small degree of self-interference or no self-interference.

[0104] Item A-3: Third feedback information, indicating that the terminal cannot decode the first object; here, being unable to decode the first object can indicate that the terminal is unable to decode the first object due to excessive self-interference caused by simultaneous transmission and reception, resulting in receiver saturation (or blocking). In this case, the terminal can skip decoding the first object and directly feed back the first target feedback information of the third feedback information.

[0105] It should be noted that in items A-1 to A-3, these three types of feedback information do not distinguish between the terminal's operating mode; that is, they can be used in either full-duplex or half-duplex mode on the terminal side. For example, in some time-domain units, the terminal operates in full-duplex mode (simultaneous transmission and reception), while in other time-domain units, the terminal operates in half-duplex mode (not simultaneous transmission and reception).

[0106] Item A-4: Fourth feedback information, indicating that the terminal failed to decode the first object in half-duplex mode on the terminal side;

[0107] Item A-5: The fifth feedback information indicates that the terminal failed to decode the first object in full-duplex mode on the terminal side;

[0108] Item A-6: The sixth feedback information indicates that the terminal cannot decode the first object in full-duplex mode on the terminal side;

[0109] Item A-7: The seventh feedback information indicates that the first object was correctly decoded in half-duplex mode on the terminal side;

[0110] Item A-8: The eighth feedback information indicates that the first object was correctly decoded in full-duplex mode on the terminal side.

[0111] In items A-4 and A-7 above, the terminal-side half-duplex mode refers to a terminal being able to receive or transmit only within a single time unit. It is evident that in terminal-side half-duplex mode, there is no simultaneous transmission and reception, thus avoiding self-interference between uplink transmission and downlink reception caused by simultaneous transmission and reception. In this case, the terminal receiving the first target feedback information of the first object can indicate whether the decoding was successful or failed, but there is no situation where decoding is impossible. Therefore, in terminal-side half-duplex mode, the terminal receiving the first target feedback information of the first object can exist in two states: the fourth feedback information and the seventh feedback information. Thus, the first target feedback information in this case can be referred to as the two-state first target feedback information.

[0112] Furthermore, in items A-5, A-6, and A-8 above, the first target feedback information received by the terminal in full-duplex mode is differentiated. Specifically, if the terminal can correctly decode the first object in full-duplex mode, the first target feedback information is the eighth feedback information; if decoding fails, it is the fifth feedback information; and if decoding is impossible, it is the sixth feedback information. Therefore, in this case, the first target feedback information received by the terminal can indicate one of three states: correct decoding, decoding failure, or inability to decode. Thus, in half-full-duplex mode, the first target feedback information received by the terminal can exist in these three states: the fifth, sixth, and eighth feedback information. In this case, the first target feedback information can be called multi-state first target feedback information.

[0113] It is understandable that each of the feedback information items A-1 to A-8 above can be understood as a state of the feedback information of the first objective mentioned above.

[0114] It should be noted that, in the embodiments of this application, both the correct decoding of the first object by the terminal and the failure to decode the first object are due to the terminal's receiver not being saturated and thus being able to decode the first object.

[0115] Furthermore, to facilitate understanding of items A-1 to A-8 above, taking PDSCH as the first object and HARQ-ACK as the first target feedback information as an example, the specific implementation of a combination of several items is illustrated below:

[0116] Example 1:

[0117] The meaning of the HARQ-ACK state for a PDSCH feedback from the network-side device configuration terminal is shown in Table 1, which is an example of a multi-state HARQ-ACK with 2 bits.

[0118] Table 1. Meaning of different HARQ-ACK states (Example 1)

[0119]

[0120] As shown in Table 1, when the terminal's receiver is not saturated, the terminal can receive the PDSCH and attempt to decode it, but the decoding may fail; when the terminal's receiver is saturated, the terminal cannot decode the PDSCH.

[0121] For example Figure 8 As shown, for PDSCH1, due to the simultaneous transmission of UL, the self-interference is large, and the terminal cannot decode PDSCH, so NACK_2 is fed back; for PDSCH2, due to the large interference or poor channel conditions, the terminal fails to decode PDSCH, so NACK_1 is fed back; for PDSCH3, the terminal successfully decodes PDSCH and feeds back ACK.

[0122] It should be noted that ACK indicates positive confirmation, while NACK indicates negative confirmation.

[0123] Example 2:

[0124] The meaning of the HARQ-ACK state for a PDSCH feedback from the network-side device configuration terminal is shown in Table 2, which is an example of a multi-state HARQ-ACK with 2 bits.

[0125] Table 2. Meaning of different HARQ-ACK states (Example 2)

[0126]

[0127] Example 3:

[0128] The network configures the meaning of the UE's HARQ-ACK state for a PDSCH feedback, distinguishing between full-duplex and half-duplex operations. Table 3 shows an example of a multi-state HARQ-ACK with 2 bits.

[0129] Table 3. Meaning of different HARQ-ACK states (Example 3)

[0130]

[0131]

[0132] As shown in Table 3, for a PDSCH that is not transmitted simultaneously, the terminal can return Ack1 and NACK_1.

[0133] For a PDSCH transmitted simultaneously, the terminal can provide feedback Ack2, NACK_1, and NACK_2.

[0134] Here, "simultaneously transmitted PDSCH" means that the PDSCH transmission is an uplink transmission within a time unit.

[0135] As can be seen from Examples 1 to 3 above, multi-state HARQ-ACK can help the network side obtain the terminal's self-interference cancellation capability more accurately and quickly (i.e., notify the network side device whether simultaneous transmission causes the terminal's receiver to saturate), thus providing a reference for subsequent scheduling of the terminal's simultaneous transmission.

[0136] For NACKs caused by strong interference within an intra-cell and between inter-cells (i.e., NACK due to receiver unsaturation) and NACKs caused by self-interference blocking (i.e., NACK due to receiver saturation), network-side equipment can employ different scheduling strategies. For example, for NACKs caused by strong interference from the same or different frequencies within intra-cells and inter-cells, network-side equipment can subsequently change DL scheduling resources. For NACKs caused by self-interference blocking, network-side equipment can reduce UL transmit power, use a larger UL and DL frequency domain spacing (i.e., guard band), and change the spatial parameter pairs of UL and DL (e.g., beam pairs). Therefore, multi-state HARQ-ACK can assist network-side equipment in adopting different scheduling strategies, improving the efficiency of the network in obtaining terminal self-interference cancellation capability information through training.

[0137] Optionally, before the terminal sends the first target feedback information for the first object, the method further includes the following step B-1:

[0138] Step B-1: The terminal determines the first target feedback information based on the sum of the power of the received signals of the first object (e.g., the power of all received signals) and the target parameters;

[0139] The target parameter includes at least one of the following C-1 to C-2:

[0140] C-1: (Downlink subband) In-band general blocker power;

[0141] Item C-2: (Downlink subband) Adjacent channel interfering signal power;

[0142] C-3: (Downlink subband) In-band narrowband blocker power.

[0143] The power of the received signal of the aforementioned terminal includes the power received from interference and noise.

[0144] Therefore, the terminal can determine whether its receiver is saturated by comparing the sum of the power of the received signals of the first object (e.g., the sum of the power of all received signals) with at least one of C-1 to C-3 above, thereby determining whether it can decode the first object and thus determining the first target feedback information. Here, if the terminal's receiver is not saturated, it means that it can decode the first object; if the terminal's receiver is saturated, it means that it cannot decode the first object.

[0145] Optionally, step B-1 above, "the terminal determines the first target feedback information based on the sum of the power of the received signals from the first object and the target parameters," includes:

[0146] If the sum of the power of the received signals of the first object (e.g., the sum of the power of all received signals) is greater than at least one power included in the target parameter, the terminal determines that it is unable to decode the first target feedback information of the first object.

[0147] If the sum of the power of the received signals of the first object (e.g., the sum of the power of all received signals) is less than or equal to the power of each of the target parameters, the terminal determines an indication that the terminal is capable of decoding the first target feedback information of the first object.

[0148] Therefore, if the sum of the power of the received signals of the first object (e.g., the sum of the power of all received signals) is greater than at least one of C-1 to C-3 above, it indicates that the receiver of the terminal is saturated and cannot decode the first object; if the sum of the power of the received signals of the first object (e.g., the sum of the power of all received signals) is less than or equal to each of C-1 to C-3 above, it indicates that the receiver of the terminal is not saturated and can decode the first object.

[0149] Optionally, different first time units may have different parameters for at least one of the following:

[0150] Frequency domain resources of the first sub-band;

[0151] The received power corresponding to the first sub-band;

[0152] Spatial parameters corresponding to the first sub-band;

[0153] Frequency domain resources of the second sub-band;

[0154] The transmission power corresponding to the second sub-band;

[0155] The spatial parameters corresponding to the second sub-band.

[0156] It is understood that the different frequency domain resources, different received power, and different spatial parameters of the first sub-band, and the different frequency domain resources, different received power, and different spatial parameters of the second sub-band, can be determined based on the self-interference measurement information configured by the network-side equipment; wherein, the self-interference measurement configuration information includes at least one of the following: configuration information for different frequency domain resources, configuration information for different power, and configuration information for different uplink and downlink transmission spatial parameters.

[0157] In this embodiment, in order to perform appropriate service scheduling for the terminal, the network-side device requires the terminal to perform interference measurement and reporting to obtain the terminal's self-interference suppression capability. One implementation is that the network side configures or instructs self-interference measurement configuration information for the terminal, so that the terminal receives a first object according to the self-interference measurement configuration information and sends the first target feedback information of the first object, so that the network-side device can determine the degree of self-interference that the terminal simultaneously transmits and receives based on the first target feedback information, thereby obtaining the terminal's self-interference suppression capability. The process of the terminal receiving the first object and sending the first target feedback information of the first object according to the self-interference measurement configuration information can also be referred to as self-interference measurement training.

[0158] It is understood that the first object can be a signal or channel used for measurement without carrying data information; or, the first object can also be a downlink signal or channel carrying data information that is normally transmitted between the terminal and the network-side device. Therefore, in this embodiment, training for self-interference measurement can be achieved solely through the signal or channel used for measurement; or training for self-interference measurement can be achieved during the actual transmission process between the terminal and the network-side device. The training for self-interference measurement during the actual transmission process between the terminal and the network-side device can be periodic, so that the training for self-interference measurement can be an iterative process.

[0159] It should be noted that the self-interference measurement configuration information mentioned above includes spatial parameters for different frequency domain resources, different power levels, and different uplink and downlink transmissions. During the training process for self-interference measurement, a controlled variable method can be used to combine these parameters to obtain measurements of the degree of self-interference under different parameter combinations. This allows network-side equipment to accurately determine more suitable uplink and downlink transmission parameters for the terminal, thereby achieving better throughput.

[0160] For example, network-side devices can configure or instruct terminals to periodically transmit uplinks using different frequency resources (and / or different PRB numbers), different power levels, and different spatial parameters, while simultaneously configuring or scheduling downlink transmissions. Based on these configurations, terminals receive PDSCH or SPS PDSCH and send HARQ-ACK feedback, enabling network-side devices to determine the impact of self-interference (SI) on downlink reception when terminals transmit and receive simultaneously.

[0161] For example, such as Figure 9 As shown, the network-side device configures or instructs the terminal to periodically transmit L uplink channels or signals with bandwidth M, spatial parameters N, and power parameters K. These L uplink channels or signals span the UL subband bandwidth of the terminal's full-duplex mode. It is understandable that... Figure 9 Only the uplink and downlink resource allocation in the time and frequency domains of the terminal is shown within one cycle during the training process of self-interference measurement. For example, in... Figure 9 In this process, multiple uplink transmissions use the same power parameter A but transmit on different frequency resources, while downlink reception uses the same frequency resource B. This allows us to obtain the self-interference situation of different uplink frequency domain transmissions based on power parameter A on the transmission of downlink frequency B.

[0162] Alternatively, the control variable method can be used to adjust the distribution of uplink and downlink in the time and frequency domains of the terminal, and different spatial parameters, power parameters, etc., can be selected to receive PDSCH and send HARQ-ACK of PDSCH.

[0163] During the training process for self-interference measurement, the network-side device can configure the training period for the terminal. Based on the first target feedback information received within this period, the network-side device can adjust at least one of the allowed uplink and downlink transmission parameters in full-duplex mode on the terminal side. For example, in... Figure 9 In this process, the terminal receives PDSCH1 within the time unit indicated by t1 and sends back HARQ-ACK for PDSCH1 within the corresponding time unit. The network-side device can indicate in which uplink time unit to send back HARQ-ACK for PDSCH1, for example, indicating that it should send back HARQ-ACK for PDSCH1 within the time unit indicated by t2. If the HARQ-ACK for PDSCH1 received by the network-side device indicates that PDSCH cannot be decoded, it means that the configuration parameters of the UL transmission transmitted simultaneously with PDSCH1 are not suitable. The configuration information of the UL transmission transmitted simultaneously with PDSCH1 can be adjusted to reduce the self-interference of the UL transmission on the reception of PDSCH1.

[0164] Optionally, the method further includes:

[0165] If at least one of the uplink configuration information and downlink configuration information used by the terminal for transmission satisfies the target condition with the second transmission information, the terminal skips decoding the first object and sends the first target feedback information indicating that the first object cannot be decoded, or the second target feedback information indicating that decoding the first object has failed.

[0166] The second transmission information includes at least one of the uplink transmission parameters and downlink transmission parameters allowed in the full-duplex mode on the terminal side.

[0167] It should be noted that the second transmission information may be the same as the first transmission information mentioned above, that is, the second transmission information may be determined by the network-side device based on the feedback information of the first target; or, the second transmission information may be different from the first transmission information, for example, the second transmission information may be predetermined.

[0168] The following explains the situation determined by the second transmission network side device based on the feedback information from the first target:

[0169] After the terminal performs the self-interference measurement training as described above, it receives the second transmission information configured or indicated by the network-side device. If, during subsequent transmission, the uplink and downlink configuration information used by the terminal for uplink and downlink transmission actually meets the target conditions with the second transmission information, the terminal can skip decoding the first object (thereby saving terminal power) and send a first target feedback information indicating failure to decode the first object (e.g., one of the second, fourth, and fifth feedback information mentioned above), or a first target feedback information indicating inability to decode the first object (e.g., one of the third and sixth feedback information mentioned above).

[0170] If at least one of the uplink configuration information and downlink configuration information used by the terminal for transmission satisfies the target conditions with the second transmission information, and the terminal is in full-duplex mode, then the terminal can send a first target feedback information to the network-side device indicating that it cannot decode the first object. This allows the network-side device to schedule downlink data retransmission based on the first target feedback information. Here, the retransmission scheduling can be chosen to avoid the impact of uplink transmission, for example, only DL transmission (i.e., half-duplex transmission).

[0171] Optionally, the uplink transmission parameters in the first transmission information, or the uplink transmission parameters in the second transmission information, include at least one of the following D-1 to D-9:

[0172] D-1: First parameter, which is the maximum transmit power of the second object allowed in full-duplex mode on the terminal side, and the second object includes at least one of uplink channel and uplink signal;

[0173] D-2: Second parameter, which is the maximum transmission bandwidth of the second object allowed in full-duplex mode on the terminal side;

[0174] D-3: The third parameter is the minimum frequency domain interval between the frequency domain resources of the second object and the frequency domain resources of the first object allowed in full-duplex mode on the terminal side.

[0175] D-4: Fourth parameter, which includes: spatial parameter pairs of the first object and the second object allowed by the full-duplex mode on the terminal side;

[0176] D-5: The fifth parameter, which is the maximum index value of the modulation and coding strategy (MCS) of the Physical Uplink Shared Channel (PUSCH) allowed to be transmitted in full-duplex mode on the terminal side.

[0177] D-6: The sixth parameter, which is the maximum code rate of PUSCH transmission allowed in full-duplex mode on the terminal side;

[0178] D-7: The seventh parameter is the maximum number of bits per resource element of the PUSCH that is allowed to be sent in full-duplex mode on the terminal side.

[0179] Item D-8: Eighth parameter, the eighth parameter is: the maximum frequency domain interval between the frequency domain resources of the second object allowed in the full-duplex mode on the terminal side and the first protection band, the first protection band is the reserved protection band between the uplink subband and the downlink subband in the half-duplex mode on the network side;

[0180] Item D-9: Ninth parameter, which is the target open-loop power parameter. The target open-loop power parameter is different from the power control parameter currently used by the terminal (for example, the target open-loop power parameter includes the open-loop power parameter used for ultra-reliable low-latency (URLLC) services).

[0181] The downlink transmission parameters in the first transmission information, or the downlink transmission parameters in the second transmission information, include at least one of the following F-1 to F-4:

[0182] F-1: The third parameter;

[0183] F-2: The fourth parameter;

[0184] F-3: The tenth parameter, which is the minimum downlink received signal-to-interference-plus-noise ratio (SINR) allowed in full-duplex mode on the terminal side;

[0185] F-4: Parameter 11, which is the maximum reduction in power of a third object relative to the power of a reference signal allowed in full-duplex mode on the terminal side, wherein the third object includes at least one of the Physical Downlink Shared Channel (PDSCH) and the Demodulation Reference Signal (DMRS).

[0186] Therefore, the network-side device can determine at least one of the parameters D-1 to D-9 and F-1 to F-4 based on the first target feedback information sent by the terminal, and configure it as the first transmission information for the terminal.

[0187] Alternatively, at least one of the parameters D-1 to D-9 and F-1 to F-4 can be predetermined as the second transmission information.

[0188] Optionally, the target condition includes at least one of the following E-1 to E-11:

[0189] E-1: The power of transmitting the second object in a single time-domain unit is greater than the first parameter;

[0190] For example, such as Figure 10 As shown, the network-side equipment configures the terminal to transmit uplink power Y1 in time domain unit X (e.g., symbol or time slot) for full-duplex transmission. If the terminal's transmit power in time domain unit X is greater than Y1, the terminal transmits the UL channel or signal and provides NACK feedback for PDSCH. In this case, the terminal can skip decoding PDSCH. Here, NACK can be either the NACK in the multi-state HARQ-ACK described above, or the NACK in the two-state HARQ-ACK described above.

[0191] E-2: The transmission bandwidth of the second object in a single time domain unit is greater than the second parameter;

[0192] For example, such as Figure 11 As shown, the network-side equipment configures the terminal to have a maximum uplink transmission bandwidth of Y² RBs for full-duplex transmission in time domain unit X (e.g., symbol or time slot). If the terminal's bandwidth for transmitting UL in time domain unit X is greater than Y² RBs, then the terminal transmits the UL channel or signal and provides a NACK response for PDSCH. In this case, the terminal can skip decoding PDSCH. Here, NACK can be either the NACK in the multi-state HARQ-ACK described above, or the NACK in the two-state HARQ-ACK described above.

[0193] E-3: The interval between the frequency domain resources of the second object and the frequency domain resources of the first object in a single time domain unit is less than or equal to the third parameter;

[0194] For example, such as Figure 12 As shown, the network device can be configured so that the minimum frequency domain interval between the uplink and downlink transmission frequency domain resources for full-duplex transmission in time domain unit X (e.g., symbol or time slot) is Y3 RBs. If the interval between the terminal transmitting UL and receiving DL in time domain unit X is greater than Y3 RBs, then the terminal transmits the UL channel or signal and provides NACK feedback for PDSCH. In this case, the terminal can skip decoding PDSCH. Here, NACK can be the NACK in the multi-state HARQ-ACK mentioned above, or the NACK in the two-state HARQ-ACK mentioned above. Y3 can include the network-side full-duplex GB, and a size greater than GB.

[0195] Item E-4: The spatial parameters received downlink and transmitted uplink in a single time domain unit are not included in the spatial parameter pairs included in the fourth parameter.

[0196] For example, such as Figure 13 As shown, the network-side device can configure the terminal to perform full-duplex transmission in time domain unit X (e.g., symbol or time slot) with a set of beam pairs (x_i, y_i) for uplink transmission and downlink reception, where i is greater than or equal to 1. If the beams for UL transmission and DL reception by the terminal in time domain unit X do not belong to (x_i, y_i), then the terminal transmits the UL channel or signal and provides a NACK for PDSCH feedback. At this time, the terminal can skip decoding PDSCH. Here, NACK can be the NACK in the multi-state HARQ-ACK mentioned above, or the NACK in the two-state HARQ-ACK mentioned above.

[0197] For simultaneous transmission of the Physical Uplink Control Channel (PUCCH) and PDSCH, the set of beam pairs (x_i, y_i) can be (PUCCH-SpatialRelationInfo_i, TCIstate_i).

[0198] For simultaneous transmission of the Physical Uplink Shared Channel (PUSCH) and PDSCH, the set of beam pairs (x_i, y_i) can be (srs-ResourceIndicator_i, TCI state_i).

[0199] Wherein, PUCCH-SpatialRelationInfo_i represents the spatial parameters used by PUCCH, srs-ResourceIndicator_i represents the spatial parameters used by PUSCH and SRS, and TCI state_i represents the spatial parameters used by PDSCH.

[0200] E-5: The index value of the MCS of the transmitted PUSCH in a single time-domain unit is greater than the fifth parameter;

[0201] For example, a network device can be configured such that when a terminal performs full-duplex transmission in time domain unit X (e.g., a symbol or time slot), the maximum index value of the MCS for transmitting PUSCH is Y5. If, during simultaneous transmission, the MCS index value for transmitting PUSCH in time domain unit X is greater than Y5, then the terminal transmits a UL channel or signal and provides a NACK response for PDSCH. In this case, the terminal can skip decoding PDSCH. Here, NACK can be either the NACK in the multi-state HARQ-ACK described above, or the NACK in the two-state HARQ-ACK described above.

[0202] E-6: The code rate of transmitting PUSCH in a single time domain unit is greater than the sixth parameter;

[0203] For example, a network device can be configured so that the maximum code rate for sending PUSCH in time domain unit X (e.g., symbol or time slot) during full-duplex transmission is Y6. If the terminal transmits simultaneously and the code rate for sending PUSCH in time domain unit X is greater than Y6, then the terminal sends a UL channel or signal and provides a NACK response for PDSCH. In this case, the terminal can skip decoding PDSCH. Here, NACK can be either the NACK in the multi-state HARQ-ACK described above, or the NACK in the two-state HARQ-ACK described above.

[0204] E-7: The number of bits for each resource element (RE) in a single time-domain unit of PUSCH is greater than the seventh parameter;

[0205] For example, a network device can be configured so that the maximum number of bits per RE of PUSCH transmitted by the terminal in time domain unit X (e.g., symbol or time slot) during full-duplex transmission is Y7. If, during simultaneous transmission, the number of bits per RE of PUSCH transmitted in time domain unit X is greater than Y7, then the terminal transmits a UL channel or signal and provides a NACK feedback for PDSCH. In this case, the terminal can skip decoding PDSCH. Here, NACK can be either the NACK in the multi-state HARQ-ACK described above, or the NACK in the two-state HARQ-ACK described above.

[0206] E-8: In a single time-domain unit, the frequency domain resource of the second object is greater than the frequency domain interval of the first guard band than the eighth parameter;

[0207] For example, a network device can be configured such that when a terminal performs full-duplex transmission in time domain unit X (e.g., a symbol or a time slot), the frequency domain interval between the frequency domain resources of the second object and the first guard band is at most Y8. If, during simultaneous transmission, the frequency domain interval between the frequency domain resources of the second object and the first guard band in time domain unit X is greater than Y8, then the terminal sends a UL channel or signal and provides a NACK response for the PDSCH. In this case, the terminal can skip decoding the PDSCH. Here, the NACK can be either the NACK in the multi-state HARQ-ACK described above, or the NACK in the two-state HARQ-ACK described above.

[0208] E-9: The second object is transmitted in a single time-domain unit using the ninth parameter;

[0209] For example, if the terminal transmits simultaneously, and in time domain unit X, uses the target open-loop power parameters (i.e., another set of parameters additionally configured on the network side, such as the open-loop power parameters used for Ultra-Reliable Low-Latency (URLLC) services) to send a second object (i.e., an uplink signal or channel), then the terminal will respond with a NACK for the PDSCH, and the terminal can skip decoding the PDSCH. Here, the NACK can be the NACK in the multi-state HARQ-ACK described above, or the NACK in the two-state HARQ-ACK described above.

[0210] E-10: The downlink received SINR in a single time-domain unit is less than or equal to the tenth parameter;

[0211] For example, a network device can be configured to set the minimum downlink channel / signal received SINR of Y4 for full-duplex transmission in time domain unit X (e.g., symbol or time slot). If the terminal transmits simultaneously, and the DL received SINR in time domain unit X is less than Y4, then the terminal sends the UL channel or signal and provides a NACK for PDSCH. In this case, the terminal can skip decoding the PDSCH. Here, NACK can be either the NACK in the multi-state HARQ-ACK described above, or the NACK in the two-state HARQ-ACK described above.

[0212] Item E-11: The reduction in power of the third object relative to the power of the reference signal in a single time-domain unit is greater than the eleventh parameter. Here, the reference signal can be a Channel State Information-Reference Signal (CSI-RS) or a Synchronization Signal Block (SSB).

[0213] For example, a network device can be configured such that when a terminal performs full-duplex transmission in time domain unit X (e.g., a symbol or time slot), the power reduction of PDSCH or DMRS relative to CSI-RS is at most Y9. Then, if the power reduction of PDSCH or DMRS relative to CSI-RS in time domain unit X is greater than Y9, the terminal transmits a UL channel or signal and provides a NACK for PDSCH, allowing the terminal to skip decoding PDSCH. This NACK can be either the NACK in the multi-state HARQ-ACK described above, or the NACK in the two-state HARQ-ACK described above.

[0214] Optionally, the method further includes:

[0215] The terminal receives first indication information, which indicates at least one state for deactivating feedback information. The state of the feedback information includes at least one of the aforementioned A-1 to A-8, and is determined by protocol agreement or network-side device configuration. In this embodiment, the state of the feedback information can be activated by default or activated by indication information; for example, the terminal receives second indication information, which indicates at least one state for activating feedback information.

[0216] In the first to eighth feedback information mentioned in items A-1 to A-8 above, each feedback information belongs to a state of the above feedback information. Therefore, deactivating at least one state of the feedback information here can be understood as deactivating at least one state of the feedback information.

[0217] For example, when the first target feedback information includes the first feedback information, the second feedback information, and the third feedback information mentioned above, these three states of the first target feedback information can be deactivated here.

[0218] Therefore, after the terminal performs self-interference measurement training and the network side obtains the terminal's self-interference cancellation capability information, the network-side device can instruct the terminal to activate at least one state of the first target feedback information. Only two states of feedback information need to be fed back according to existing technology, thus saving resources. For example, when the first target feedback information is HARQ-ACK, a two-state HARQ-ACK (containing only ACK and NACK) can be used.

[0219] Understandably, after the terminal has been trained to perform self-interference measurement, the network-side device may not instruct the terminal to activate at least one state of feedback information.

[0220] In addition, the following situations may also exist in the embodiments of this application:

[0221] Scenario 1:

[0222] When the terminal's receiver is saturated (or blocked), the terminal may not receive or decode the PDSCH, but directly feed back a HARQ-ACK to indicate that the PDSCH cannot be decoded. During retransmission scheduling, the terminal does not merge the HARQ with the previous reception.

[0223] Scenario 2:

[0224] In full-duplex mode on the terminal side, if the terminal decoding fails (i.e., the receiver is not saturated and PDSCH decoding fails) and at least one of the uplink configuration information and downlink configuration information used by the terminal for transmission satisfies the above-mentioned target conditions with the first transmission information or the second transmission information, the terminal can calculate the index of the second modulation and coding scheme (MCS) / channel quality indicator (CQI) required in full-duplex state based on the received SINR of PDSCH or DMRS. At the same time as feeding back the first target feedback information used to indicate decoding failure, the terminal reports at least one of the target difference value corresponding to CQI and the target difference value corresponding to MCS. Here, the target difference value corresponding to CQI is obtained by comparing (i.e., subtracting) the index of the second CQI and the first CQI as described above; the target difference value corresponding to MCS is obtained by comparing (i.e., subtracting) the index of the second MCS and the first MCS as described above.

[0225] For example, such as Figure 14As shown, CQI 1 is the CQI in half-duplex mode (e.g., index 13), and CQI 2 is the CQI calculated in full-duplex mode (e.g., index 8). When the terminal sends a HARQ-ACK to PDSCH 2, it also sends back the target difference value corresponding to the CQI (i.e., 5 = index 13 - index 8). The target difference value corresponding to the CQI can be encoded as z bits, configured by the network-side device. For example, the 2-bit case is shown in Table 4 below, where z1 to z4 are configured by the network-side device.

[0226] Table 4 shows examples of target differences corresponding to CQI.

[0227] Bit Delta CQI 00 (i.e., 0) <＝x1 01 (i.e., 1) X2 10 (i.e., 2) X3 11 (i.e., 3) >x4

[0228] It is understandable that the reporting method of the target difference corresponding to different states of HARQ-ACK can also be configured (that is, it is possible to configure which one or more of the target difference corresponding to CQI and MCS that the terminal needs to report to the network-side device under different states of HARQ-ACK). For example, when the terminal's receiver is saturated, the terminal feeds back to the network-side device a HARQ-ACK indicating that it cannot decode PDSCH, as well as the target difference corresponding to CQI or the target difference corresponding to MCS.

[0229] Among them, the target difference value corresponding to CQI and the target difference value corresponding to MCS are reported by the network side device on the terminal, so that the network can use the appropriate CQI level and MCS level for subsequent DL scheduling, thereby improving spectrum utilization efficiency through reasonable scheduling.

[0230] Secondly, embodiments of this application provide a full-duplex communication method, such as... Figure 15 As shown, the method may include the following steps 1501 to 502:

[0231] Step 1501: The network-side device sends the first object in the first time unit.

[0232] The first time unit includes: a first subband supporting the reception of the first object and a second subband supporting the transmission of the second object, wherein the first object includes at least one of a downlink channel and a downlink signal, and the second object includes at least one of an uplink channel and an uplink signal.

[0233] Step 1502: The network-side device receives first target feedback information for the first object.

[0234] The first target feedback information is used to indicate whether the terminal can decode the first object.

[0235] Therefore, it can be seen that the first time unit supports simultaneous transmission and reception, that is, the network-side device uses full-duplex within the first time unit.

[0236] Optionally, the first target feedback information includes Hybrid Automatic Repeat Request Acknowledgment (HARQ-ACK).

[0237] In addition, the following two full-duplex modes exist in the embodiments of this application:

[0238] Network-side full-duplex mode: that is, the network side application is full-duplex, and the terminal side application is half-duplex.

[0239] Terminal full-duplex mode: This means that both network-side applications and terminal-side applications are full-duplex.

[0240] Here, the UE side uses half-duplex, meaning that within one time unit, the terminal can only perform uplink transmission or downlink reception; the UE side uses full-duplex, meaning that within one time unit, the terminal can perform both uplink transmission and downlink reception simultaneously.

[0241] Furthermore, the aforementioned first object pertains to downlink, while the aforementioned first target feedback information pertains to uplink. When the terminal uses full-duplex operation, it can simultaneously receive downlink data and transmit uplink data within a single time unit. In this case, the uplink transmission by the terminal can cause self-interference to the downlink reception. However, in this embodiment, the terminal can use the first target feedback information received by the first object to indicate whether it can decode the first object. Whether or not the first object can be decoded is related to the degree of self-interference in the simultaneous transmission and reception. Thus, in this embodiment, the terminal can use the first target feedback information received by the downlink to indicate to the network-side device whether it can decode the first object (i.e., if the terminal can decode the first object, it indicates that the degree of self-interference is small, the terminal's receiver is not saturated, and therefore the first object can be decoded; if the terminal cannot decode the first object, it indicates that the degree of self-interference is large, the terminal's receiver is saturated, and therefore the first object cannot be decoded). Consequently, the network-side device can obtain the degree of self-interference in the simultaneous transmission and reception of the terminal (i.e., obtain the terminal's self-interference cancellation capability information).

[0242] As can be seen from steps 1501 to 1502 above, in this embodiment, the terminal can use the first target feedback information received downlink to report to the network-side device whether it can decode the first object, thereby indicating the degree of self-interference of simultaneous transmission and reception by the terminal. Therefore, in this embodiment, the network-side device can use the first target feedback information of the terminal to report the first object received, to know the self-interference situation of simultaneous transmission and reception by the terminal, providing a basis for the network-side device to schedule uplink and downlink transmissions, and improving the downlink reception performance of the terminal.

[0243] Optionally, the method further includes:

[0244] The network-side device sends first transmission information based on the first target feedback information, wherein the first transmission information includes at least one of the uplink transmission parameters and downlink transmission parameters allowed in the full-duplex mode on the terminal side.

[0245] Therefore, after receiving the first target feedback information sent by the terminal, the network-side device determines the terminal's first transmission information based on the first target feedback information and configures it for the terminal.

[0246] In addition, the first target feedback information is used to indicate whether the terminal can decode the first object. In this way, the network-side device can know the degree of self-interference of the terminal, and adjust at least one of the uplink transmission parameters and downlink transmission parameters allowed by the terminal in full-duplex mode on the terminal side to obtain the aforementioned first transmission information, so as to reduce the self-interference of uplink transmission on downlink reception when the terminal transmits and receives simultaneously.

[0247] Optionally, the downlink channel includes at least one of the following:

[0248] Physical Downlink Shared Channel (PDSCH);

[0249] Downlink control channel (e.g., a channel carrying downlink control information (DCI)).

[0250] Therefore, it can be seen that the terminal can receive PDSCH and send PDSCH feedback information. Here, the PDSCH feedback information is used to indicate whether the terminal can decode PDSCH. In this way, after the network-side device receives the PDSCH feedback information, it can determine the terminal's first transmission information based on the PDSCH feedback information, so that the terminal's uplink transmission reduces self-interference with the PDSCH reception.

[0251] Similarly, the terminal can receive the downlink control channel and send feedback information of the downlink control channel. Here, the feedback information of the downlink control channel is used to indicate whether the terminal can decode the downlink control channel. In this way, after the network-side device receives the feedback information of the downlink control channel, it can determine the terminal's first transmission information based on the feedback information of the downlink control channel, so that the uplink transmission of the terminal reduces self-interference with the reception of the downlink control channel.

[0252] Furthermore, simultaneous receiving and transmitting by a communication device can cause self-interference. To ensure transmission in the direction of interference, the communication device needs to have self-interference cancellation capabilities. For example, a guard band (GB) is typically reserved between UL and DL transmissions to achieve frequency isolation and reduce self-interference. Since the self-interference cancellation capability of the terminal is usually weaker than that of the network-side equipment, the guard band required for simultaneous receiving and transmitting by the terminal is larger than that required for simultaneous receiving and transmitting by the network side; that is, more Physical Resource Blocks (PRBs) are needed as guard bands.

[0253] Optionally, in this embodiment of the application, the width of the first protection band can be set to be greater than the width of the second protection band; wherein, the first protection band is a reserved protection band between the uplink subband and the downlink subband in the full-duplex mode on the network side; and the second protection band is a reserved protection band between the uplink subband and the downlink subband in the full-duplex mode on the terminal side.

[0254] Optionally, the first target feedback information includes at least one of the following A-1 to A-8:

[0255] Item A-1: ​​First feedback information, indicating that the first object was correctly decoded;

[0256] Item A-2: Second feedback information, indicating that the terminal failed to decode the first object;

[0257] Item A-3: Third feedback information, indicating that the terminal is unable to decode the first object;

[0258] Item A-4: Fourth feedback information, indicating that the terminal failed to decode the first object in half-duplex mode on the terminal side;

[0259] Item A-5: The fifth feedback information indicates that the terminal failed to decode the first object in full-duplex mode on the terminal side;

[0260] Item A-6: The sixth feedback information indicates that the terminal cannot decode the first object in full-duplex mode on the terminal side;

[0261] Item A-7: The seventh feedback information indicates that the first object was correctly decoded in half-duplex mode on the terminal side;

[0262] Item A-8: The eighth feedback information indicates that the first object was correctly decoded in full-duplex mode on the terminal side.

[0263] For details regarding items A-1 to A-8, please refer to the previous text; they will not be repeated here.

[0264] Optionally, different first time units may have different parameters for at least one of the following:

[0265] Frequency domain resources of the first sub-band;

[0266] The received power corresponding to the first sub-band;

[0267] Spatial parameters corresponding to the first sub-band;

[0268] Frequency domain resources of the second sub-band;

[0269] The transmission power corresponding to the second sub-band;

[0270] The spatial parameters corresponding to the second sub-band.

[0271] It is understood that the different frequency domain resources, different received power, and different spatial parameters of the first sub-band, and the different frequency domain resources, different received power, and different spatial parameters of the second sub-band, can be determined based on the self-interference measurement information configured by the network-side equipment; wherein, the self-interference measurement configuration information includes at least one of the following: configuration information for different frequency domain resources, configuration information for different power, and configuration information for different uplink and downlink transmission spatial parameters.

[0272] In this embodiment, in order to perform appropriate service scheduling for the terminal, the network-side device requires the terminal to perform interference measurement and reporting to obtain the terminal's self-interference suppression capability. One implementation is that the network side configures or instructs self-interference measurement configuration information for the terminal, so that the terminal receives a first object according to the self-interference measurement configuration information and sends the first target feedback information of the first object, so that the network-side device can determine the degree of self-interference that the terminal simultaneously transmits and receives based on the first target feedback information, thereby obtaining the terminal's self-interference suppression capability. The process of the terminal receiving the first object and sending the first target feedback information of the first object according to the self-interference measurement configuration information can also be referred to as self-interference measurement training.

[0273] It should be noted that the self-interference measurement configuration information mentioned above includes spatial parameters for different frequency domain resources, different power levels, and different uplink and downlink transmissions. During the training process for self-interference measurement, a controlled variable method can be used to combine these parameters to obtain measurements of the degree of self-interference under different parameter combinations. This allows network-side equipment to accurately determine more suitable uplink and downlink transmission parameters for the terminal, thereby achieving better throughput.

The target open-loop power parameter is different from the power control parameter currently used by the terminal (for example, the target open-loop power parameter includes the open-loop power parameter used for ultra-reliable low-latency (URLLC) services).

[0284] The downlink transmission parameters in the first transmission information, or the downlink transmission parameters in the second transmission information, include at least one of the following F-1 to F-4:

[0285] F-1: The third parameter;

[0286] F-2: The fourth parameter;

[0306] Optionally, the method further includes:

[0308] In the preceding A-1 to A-8 items, each of the first to eighth feedback information items belongs to a state of the aforementioned first target feedback information. Therefore, deactivating at least one state of the feedback information here can be understood as deactivating at least one feedback information included in the first target feedback information.

[0309] For example, when the first target feedback information includes the first feedback information, the second feedback information, and the third feedback information mentioned above, these three states of the first target feedback information can be deactivated here.

[0310] Therefore, after the terminal performs self-interference measurement training and the network side obtains the terminal's self-interference cancellation capability information, the network-side device can instruct the terminal to activate at least one state of the first target feedback information. Only two states of feedback information need to be fed back according to existing technology, thus saving resources. For example, when the first target feedback information is HARQ-ACK, a two-state HARQ-ACK (containing only ACK and NACK) can be used.
