[0026] The technical solution provided by the embodiments of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

[0027] like Figure 2 FIG. 2 is a flow chart of a transmission method 200 provided by an exemplary embodiment of the present application. The method 200 may be, but is not limited to, executed by a terminal, and may be specifically executed by hardware or software installed in the terminal. In this embodiment, the method 200 may at least include the following steps.

[0028] S210: When a first uplink transmission and a first downlink transmission are configured or scheduled and the first uplink transmission and the first downlink transmission meet a target condition, the terminal acquires target information.

[0029] The target situation may include but is not limited to at least one of the following 11)-13).

[0030] 11) The first uplink transmission and the first downlink transmission overlap in the time domain.

[0031] The first uplink transmission and the first downlink transmission may partially overlap or completely overlap in the time domain, which is not limited here.

[0032] 12) A time domain interval between the first uplink transmission and the first downlink transmission is less than a first threshold.

[0033] Among them, the first threshold can be determined by protocol agreement, high-level configuration, network side configuration, terminal reporting, or based on at least one of terminal capabilities, subcarrier spacing, frequency band, etc., and is not limited here.

[0034] 13) The first uplink transmission and the first downlink transmission are located in the same time unit.

[0035] The time unit may be a time slot, a sub-slot, a symbol or a symbol set, etc., which is not limited here.

[0036] Then, in some embodiments, if the terminal is configured or scheduled within the time unit of the first uplink transmission and the first downlink transmission, the terminal enables or activates the first mode (for example, the base station configures it through high-level signaling), wherein the first mode includes a terminal-side full-duplex transmission mode, that is, the terminal can simultaneously perform uplink transmission and downlink transmission at the same time. Then, if the terminal simultaneously transmits the first uplink transmission and the first downlink transmission based on the first mode, the problem of the first uplink transmission interfering with the first downlink transmission may occur. Among them, the first mode can be, but is not limited to, a terminal-side full-duplex transmission mode, a terminal-side subband overlapping full-duplex transmission mode (subband overlapping Full duplex), a terminal-side subband non-overlapping full-duplex transmission (subband non-overlapping Full duplex, SBFD) mode, etc.

[0037] In this regard, the present application takes into account that when the terminal works in the full-duplex mode, the self-interference generated by the uplink transmission may be related to a variety of factors, but one of the important factors is the transmission power of the terminal. The greater the transmission power, the greater the self-interference generated. Based on this, the present application is for the situation where the terminal is configured or scheduled for the first uplink transmission and the first downlink transmission, and the first uplink transmission and the first downlink transmission meet the target situation, by obtaining information related to the transmission power of the terminal, that is, the target information, and then determining whether to use the first mode or the second mode for the first downlink transmission or the first uplink transmission according to the target information, wherein the second mode is a transmission mode other than the first mode. Therefore, by determining the transmission mode through the information related to the transmission power of the terminal, on the one hand, it is possible to solve the self-interference without reserving more resources, thereby improving the resource utilization; on the other hand, it can also avoid the problem of reserving more resources for transceiver isolation in order to solve the transmission self-interference in the related technology, thereby reducing the resource utilization, and improving the performance of the communication system.

[0038] Optionally, considering that the target information is related to the transmission power of the terminal, therefore, in this embodiment, the target information may be the transmission power, power spectrum density (PSD), etc. of the first uplink transmission, or the transmission power, power spectrum density, etc. of the downlink transmission whose receiving time is related to the sending time of the first uplink transmission, and no limitation is made here.

[0039] In addition, the second method may include but is not limited to at least one of the following 21)-22).

[0040] 21) Half-duplex transmission mode on the terminal side and half-duplex transmission mode on the network side. That is, the terminal side and the network side can only perform uplink transmission or downlink transmission at the same time.

[0041] 22) Half-duplex transmission mode on the terminal side and full-duplex transmission mode on the network side. That is, the terminal side can only perform uplink transmission or downlink transmission at the same time, while the network side can perform uplink transmission and downlink transmission at the same time.

[0042] S220: Determine, according to the target information, whether to perform the first uplink transmission or the first downlink transmission based on a first method or a second method.

[0043] In this embodiment, according to different target information, the terminal determines whether to perform the first uplink transmission or the first downlink transmission based on the first mode or the second mode according to the target information, which is not limited here.

[0044] In this embodiment, when the terminal is configured or scheduled for the first uplink transmission and the first downlink transmission, and the first uplink transmission and the first downlink transmission meet the target conditions, the terminal obtains target information related to the transmission power of the terminal, and then determines whether to perform the first uplink transmission or the first downlink transmission based on the first mode or the second mode according to the target information. Thus, by determining the transmission mode through the information related to the transmission power of the terminal, it is possible to solve self-interference without reserving more resources, thereby improving resource utilization and improving the performance of the communication system.

[0045] like Figure 3a FIG. 1 is a flow chart of a transmission method 300 provided by an exemplary embodiment of the present application. The method 300 may be, but is not limited to, executed by a terminal, and may be specifically executed by hardware or software installed in the terminal. In this embodiment, the method 300 may at least include the following steps.

[0046] S310: When a first uplink transmission and a first downlink transmission are configured or scheduled and the first uplink transmission and the first downlink transmission meet a target condition, the terminal acquires target information.

[0047] Among them, the target information is related to the transmission power of the terminal, and the target situation includes at least one of the following: the first uplink transmission and the first downlink transmission overlap in time domain; the time domain interval between the first uplink transmission and the first downlink transmission is less than a first threshold; the first uplink transmission and the first downlink transmission are in the same time unit.

[0048] It can be understood that the implementation process of S310 can refer to the relevant description in the aforementioned method embodiment 200, and achieve the same or corresponding technical effect. Of course, in addition to referring to the relevant description in the aforementioned method embodiment 200, as a possible implementation method, Figure 3a As shown, taking the autonomous determination of the terminal as an example, the implementation process of S310 may include S311, the content of which is as follows.

[0049] S311: When a first uplink transmission and a first downlink transmission are configured or scheduled by the terminal and the first uplink transmission and the first downlink transmission meet a target condition, the terminal determines the target information according to a transmission parameter corresponding to the first mode, wherein the first mode is enabled or activated in a time unit corresponding to the first uplink transmission and the first downlink transmission.

[0050] Optionally, the transmission parameters corresponding to the first mode may include but are not limited to transmission power control parameters, transmission time-frequency domain resources, modulation and coding scheme (MCS) and other parameters. Among them, the transmission power control parameters include but are not limited to maximum transmission power P CMAX , target received power P0, path loss compensation factor ɑ, etc. The transmission time-frequency domain resources may include but are not limited to transmission bandwidth, frequency hopping pattern, PUCCH resource configuration, CG PUSCH configuration and other parameters. In this embodiment, the transmission parameters corresponding to the first method can be implemented by protocol agreement, high-level configuration and other methods, and are not limited here.

[0051] In some embodiments, when the terminal determines the target information according to the transmission parameters corresponding to the first method, the determination method may include but is not limited to: the terminal determines the frequency domain resources (for example, the number of resource blocks (RB)) of the first uplink transmission according to the transmission parameters corresponding to the first method (such as frequency domain resources), and determines the target information according to the frequency domain resources of the first uplink transmission and the power control parameters corresponding to the first method, such as the transmission power or transmission power spectrum density of the first uplink transmission; or, the terminal determines the target information according to the transmission parameters corresponding to the first method (such as transmission power control parameters), such as the transmission power or transmission power spectrum density of the first uplink transmission, which is not limited here.

[0052] Based on this, in some embodiments, the target information may include but is not limited to at least one of the following 31)-34).

[0053] 31) The transmission power of the first uplink transmission.

[0054] 32) Power spectral density of the first uplink transmission.

[0055] 33) The difference between the transmission power of the first uplink transmission and the reception power of the second downlink transmission.

[0056] 34) A difference between the power spectral density of the first uplink transmission and the power spectral density of the second downlink transmission.

[0057] For the second downlink transmission mentioned in this embodiment, the receiving time of the second downlink transmission is not later than the sending start time of the first uplink transmission. That is, the second downlink transmission may be the downlink transmission received by the terminal before the sending start time of the first uplink transmission.

[0058] For example, in this embodiment, the second downlink transmission may be the downlink transmission most recently received by the terminal before sending the first uplink transmission, or may be the downlink transmission most recently received by the terminal before a first time. The first time is before the sending time of the first uplink transmission, and the first time interval with the sending time of the first uplink transmission is a first duration. It can be understood that the first time and the first duration may be implemented by protocol agreement, high-level configuration, terminal reporting, etc.

[0059] In addition, in some embodiments, for the aforementioned second downlink transmission, it can also be a downlink transmission received on the target beam, a downlink transmission received on the target beam, a downlink transmission received on the target TRP, a downlink transmission associated with a target control resource set pool index (Control resource set pool index, CORESET pool index), a downlink transmission with target space information, etc., thereby improving the reliability and accuracy of determining the target information.

[0060] Among them, the target beam, target TRP, target CORESET pool index, and target spatial information can be implemented by protocol agreement, high-level configuration, or network side configuration, or the second downlink transmission is associated with the same spatial information or the same beam pair as the first uplink transmission, which is not limited here.

[0061] S320: Determine, according to the target information, whether to perform the first uplink transmission or the first downlink transmission based on a first method or a second method.

[0062] The first mode includes a full-duplex transmission mode on the terminal side, and the second mode is a transmission mode other than the first mode.

[0063] It can be understood that the implementation process of S320 can refer to the relevant description in the aforementioned method embodiment 200, and achieve the same or corresponding technical effect. Of course, in addition to referring to the relevant description in the aforementioned method embodiment 200, as a possible implementation method, according to the difference in the target information, the terminal determines whether to perform the first uplink transmission or the first downlink transmission based on the first method or the second method according to the target information, which may include but is not limited to at least one of the following methods 1-6.

[0064] Mode 1: When the transmission power of the first uplink transmission is greater than or equal to a second threshold, or when the power spectral density of the first uplink transmission is greater than or equal to a third threshold, the terminal determines to perform the first uplink transmission or the first downlink transmission based on the second mode.

[0065] Among them, the second threshold and the third threshold mentioned in the context of this application can be implemented by base station configuration / instruction, terminal reporting, or determination according to predefined rules.

[0066] For example, when the second threshold or the third threshold is determined according to the predefined rule, the second threshold or the third threshold may be related to the transmission parameter of the first uplink transmission, such as different transmission parameters correspond to different second thresholds or third thresholds. The transmission parameters may include transmission bandwidth, transmission channel type, uplink gap, downlink gap, etc., and the transmission channel type may include physical uplink control channel (PUCCH), physical uplink shared channel (PUSCH), etc.

[0067] Mode 2: When the transmission power of the first uplink transmission is less than or equal to a second threshold, or when the power spectral density of the first uplink transmission is less than or equal to a third threshold, the terminal determines to perform the first uplink transmission or the first downlink transmission based on the first mode.

[0068] Mode 3: When a difference between the transmission power of the first uplink transmission and the receiving power of the second downlink transmission satisfies a first condition, the terminal determines to perform the first uplink transmission or the first downlink transmission based on the first mode.

[0069] Among them, the first condition mentioned in the context of this application may include that the difference between the transmission power of the first uplink transmission and the receiving power of the second downlink transmission is less than a certain threshold or falls within a certain numerical range.

[0070] Optionally, the threshold value or the value range may be implemented by base station configuration / instruction, terminal reporting, or determination according to predefined rules.

[0071] Mode 4: When the difference between the power spectrum density of the first uplink transmission and the power spectrum density of the second downlink transmission satisfies a second condition, the terminal determines to perform the first uplink transmission or the first downlink transmission based on the first mode.

[0072] Among them, the second condition mentioned in the context of this application may include that the difference between the power spectrum density of the first uplink transmission and the power spectrum density of the second downlink transmission is less than a certain threshold or falls within a certain numerical range.

[0073] Optionally, the threshold value or the value range may be implemented by base station configuration / instruction, terminal reporting, or determination according to predefined rules.

[0074] Mode 5: When the difference between the transmission power of the first uplink transmission and the receiving power of the second downlink transmission does not satisfy the first condition, the terminal determines to perform the first uplink transmission or the first downlink transmission based on the second mode.

[0075] Mode 6: When the difference between the power spectrum density of the first uplink transmission and the power spectrum density of the second downlink transmission does not satisfy the second condition, the terminal determines to perform the first uplink transmission or the first downlink transmission based on the second mode.

[0076] It is worth noting that, in some implementations, which of the aforementioned modes 1 to 6 is actually adopted by the terminal may be determined by protocol agreement, high-level configuration / instruction, or determined according to predefined rules. For example, assuming that the terminal can be determined according to predefined rules, the predetermined rules may be priority rules between the aforementioned modes 1 to 6, that is, the terminal may adopt a higher priority mode for the first uplink transmission or the first downlink transmission according to the priority order corresponding to modes 1 to 6, and no limitation is made here.

[0077] In addition, in some other embodiments, for situations such as Mode 1, Mode 5, and Mode 6, the terminal determines to perform the first uplink transmission or the first downlink transmission based on the second mode, and the process of the terminal performing the first uplink transmission or the first downlink transmission based on the second mode may include but is not limited to any one of the following 41)-46).

[0078] 41) The terminal performs the transmission with a higher priority among the first uplink transmission and the first downlink transmission, and cancels the transmission with a lower priority.

[0079] Exemplarily, if the priority of the first uplink transmission is higher than that of the first downlink transmission, then the terminal performs the first uplink transmission and cancels the first downlink transmission, and vice versa.

[0080] It is worth noting that the priority of the first uplink transmission may be its physical layer priority, such as a priority index. The priority of the first downlink transmission may be its corresponding hybrid automatic repeat request acknowledgement (HARQ-ACK) physical layer priority or codebook, such as a priority index or codebook ID.

[0081] Based on this, if the priority index of the first uplink transmission is 1, that is, the priority of the first uplink transmission is high priority and the priority of the first downlink transmission is low priority, the terminal performs the first uplink transmission and cancels the first downlink transmission, and vice versa.

[0082] 42) The terminal performs the first uplink transmission and cancels the first downlink transmission.

[0083] For example, the terminal may determine, according to a protocol agreement or the like, that when the first uplink transmission or the first downlink transmission is performed based on the second method, the first uplink transmission is performed directly and the first downlink transmission is canceled.

[0084] 43) The terminal performs the first downlink transmission and cancels the first uplink transmission.

[0085] For example, the terminal may determine, according to a protocol agreement or the like, that when the first uplink transmission or the first downlink transmission is performed based on the second method, the first downlink transmission is performed directly and the first uplink transmission is canceled.

[0086] 44) The terminal determines whether to perform the first uplink transmission or the first downlink transmission according to the transmission signal type.

[0087] Among them, the transmission signal type may include but is not limited to a physical random access channel (PRACH), a synchronization signal block (SSB), a channel state information reference signal (CSI-RS), etc.

[0088] Exemplarily, if the first uplink transmission is the PRACH, the terminal performs the first uplink transmission and delays or cancels the first downlink transmission.

[0089] Alternatively, if the first downlink transmission is the SSB or CSI-RS, the terminal performs the first downlink transmission and delays or cancels the first uplink transmission.

[0090] 45) Determining whether to perform the first uplink transmission or the first downlink transmission according to the transmission scheduling type.

[0091] The transmission scheduling types include dynamic scheduling (Dynamic Scheduling) or dynamic grant (Dynamic Grant, DG), semi-persistent scheduling (Semi-Persistent Scheduling, SPS), configured grant (configured Grant, CG) or configured transmission (configured transmission) and the like.

[0092] Exemplarily, in the first uplink transmission and the first downlink transmission, if the first uplink transmission is a dynamically scheduled transmission and the first downlink transmission is a configured transmission or SPS, the first uplink transmission is transmitted and the first downlink transmission is canceled or delayed, and vice versa.

[0093] 46) The terminal determines whether to perform the first uplink transmission or the first downlink transmission according to the scheduling time or the transmission start time.

[0094] For example, the terminal transmits the first uplink transmission and the first downlink transmission with the later scheduled time, and cancels or delays the other one; or, the terminal transmits the first uplink transmission and the first downlink transmission with the earlier transmission start time, and cancels or delays the other one.

[0095] Among them, in the case where the first uplink transmission and the first downlink transmission are scheduled by DCI, the scheduling time corresponding to the DCI is determined according to the starting symbol or ending symbol of the PDCCH or control resource set (Control resource set, CORESET) to which it is located.

[0096] It is worth noting that the terminal can determine to perform the first uplink transmission or the first downlink transmission according to any one of the aforementioned 41)-46). However, if any one of the aforementioned 41)-46) cannot determine whether to perform the first uplink transmission or the first downlink transmission, such as the two have the same priority, the same transmission signal type, the same scheduling type, or the same transmission start time, then the terminal can independently determine which one to transmit, or can combine two or more of 41)-46) to determine whether to perform the first uplink transmission or the first downlink transmission.

[0097] For example, if the priorities of the two are the same, then the terminal may further determine whether to perform the first uplink transmission or the first downlink transmission in combination with the transmission signal type or the scheduling type.

[0098] In some embodiments, when the terminal performs the first uplink transmission or the first downlink transmission based on the second method, a transmission parameter of the first uplink transmission or the first downlink transmission is determined according to a transmission parameter corresponding to the second method.

[0099] It can be understood that in some embodiments, the terminal is pre-configured with one or more sets of transmission parameters, for example, including at least one set of transmission parameters corresponding to the first method and at least one set of transmission parameters corresponding to the second method. Then, when the terminal performs the first uplink transmission or the first downlink transmission based on the second method, it can select one set from the one or more sets of pre-configured transmission parameters to determine the transmission parameters of the first uplink transmission or the first downlink transmission.

[0100] Among them, the transmission parameters corresponding to the second mode may include but are not limited to transmission power, transmission time and frequency resources, MCS, etc.

[0101] In other embodiments, for example, Mode 2, Mode 3, and Mode 4, the process in which the terminal performs the first uplink transmission or the first downlink transmission based on the first mode may include: the terminal performs the first uplink transmission and the first downlink transmission simultaneously, that is, the terminal performs the first uplink transmission and the first downlink transmission based on a full-duplex mode.

[0102] The frequency domain gap between the first uplink transmission and the first downlink transmission satisfies a condition that the gap is greater than or equal to a fourth threshold, so as to avoid problems such as overlap or partial overlap between the first uplink transmission and the first downlink transmission, or problems such as self-interference caused by the first uplink transmission to the first downlink transmission, etc. Optionally, the fourth threshold is a non-negative value, and it can be configured / indicated by the base station or determined according to a predefined rule, which is not limited here.

[0103] In addition, if the frequency domain interval between the first uplink transmission and the first downlink transmission does not satisfy a condition greater than or equal to a fourth threshold, then the terminal may perform the first uplink transmission or the first downlink transmission based on the second method, as described in 41)-46) above; or, the terminal may first perform the first uplink transmission or the first downlink transmission of part of the frequency domain resources according to rate matching (rate-matching) or puncturing (puncture) until the frequency domain interval between the first uplink transmission and the first downlink transmission satisfies a condition greater than or equal to the fourth threshold, and then perform the first uplink transmission or the first downlink transmission according to the first method (that is, perform the first uplink transmission and the first downlink transmission at the same time).

[0104] In some embodiments, when the terminal performs the first uplink transmission or the first downlink transmission based on the first mode, the transmission parameters of the first uplink transmission and the first downlink transmission are determined according to the transmission parameters corresponding to the first mode. It can be understood that in some embodiments, one or more sets of transmission parameters corresponding to the first mode are pre-configured in the terminal, then, when the terminal performs the first uplink transmission or the first downlink transmission based on the first mode, it can select one set from the one or more sets of pre-configured transmission parameters to determine the transmission parameters of the first uplink transmission or the first downlink transmission.

[0105] Among them, the transmission parameters corresponding to the first mode may include but are not limited to transmission power, transmission time and frequency resources, MCS, etc.

[0106] In this embodiment, the terminal determines the transmission mode based on the information related to the transmission power, thereby avoiding transmission interference and improving the effectiveness of the communication system.

[0107] Based on the description of the aforementioned method embodiments 200-300, the transmission method provided in the present application is exemplarily described below with reference to examples, as follows.

[0108] Example 1

[0109] like Figure 3b As shown, in a certain time unit, assuming that the terminal activates or enables the first mode, and the terminal is configured or scheduled for a first uplink transmission and a first downlink transmission, and the first uplink transmission and the first downlink transmission meet the target conditions, then the terminal obtains the transmission power Px or power spectral density Py of the first uplink transmission according to the transmission parameters corresponding to the first mode.

[0110] In this case, if the transmission power Px of the first uplink transmission is greater than or equal to the second threshold, or the power spectrum density Py of the first uplink transmission is greater than or equal to the third threshold, the first uplink transmission or the second downlink transmission is performed in accordance with the second manner. The transmission parameter corresponding to the first uplink transmission or the second downlink transmission is determined according to the transmission parameter corresponding to the second manner.

[0111] or,

[0112] If the transmission power Px of the first uplink transmission is less than or equal to the second threshold, or the power spectrum density Py of the first uplink transmission is less than or equal to the third threshold, the first uplink transmission or the first downlink transmission is performed in a first manner, such as transmitting the first uplink transmission or the first downlink transmission simultaneously. The transmission parameter corresponding to the first uplink transmission or the second downlink transmission is determined according to the transmission parameter corresponding to the first manner.

[0113] It can be understood that, for the situation of transmitting the first uplink transmission or the first downlink transmission simultaneously, the frequency domain interval between the first uplink transmission or the first downlink transmission satisfies or is greater than or equal to the fourth threshold; otherwise, the first uplink transmission or the second downlink transmission is performed in the second manner, or the first uplink transmission or the first uplink transmission of part of the frequency domain resources is performed in accordance with rate-matching or puncture, until the first uplink and the first downlink transmission are performed after the predetermined frequency domain interval requirement is met.

[0114] It can be understood that for the situation of transmitting the first uplink transmission or the first downlink transmission simultaneously, the frequency domain resources between the first uplink transmission or the first downlink transmission are respectively in the uplink subband (UL subband) and the downlink subband (DL subband) semi-statically configured by the base station through high-level signaling, wherein the subband is one or more continuous or discontinuous RBs; otherwise, the first uplink transmission or the second downlink transmission is performed in the second manner.

[0115] It can be understood that when the terminal performs the first uplink transmission or the first downlink transmission according to the second mode, the frequency domain resources of the first uplink transmission or the first downlink transmission may be outside the UL subband or DL ​​subband semi-statically configured by the base station through high-layer signaling. In this way, the base station can use more resources for uplink or downlink transmission, thereby improving data transmission rate and resource utilization.

[0116] It is worth noting that, for the first uplink transmission and the first downlink transmission in this example 1, it may include any one of the following 51)-53).

[0117] 51) The scheduling types of the first uplink transmission and the first downlink transmission are both configuration transmissions, such as semi-static downlink transmission, SSB, SPS physical downlink shared channel (Physical downlink shared channel, PDSCH), CSI-RS physical downlink control channel (Physical downlink control channel, PDCCH).

[0118] Optionally, for PDCCH, it may be a PDCCH monitoring occasion configured by the terminal, etc.

[0119] The semi-static uplink transmission may be, for example, CG PUSCH, PUCCH carrying CSI, PUCCH carrying scheduling request (SR), PUCCH carrying HARQ-ACK without corresponding scheduling DCI, periodic sounding reference signal (Sounding Reference Signal, SRS) or semi-persistent SRS (SP-SRS), etc.

[0120] 52) The scheduling type of the first uplink transmission is configuration transmission, such as semi-static uplink transmission, and the scheduling type of the first downlink transmission is dynamic scheduling, such as downlink control information (DCI) format, such as the first downlink transmission can be PDSCH scheduled by DCI 0_1, DCI 1_1, DCI 2_1, etc., or CSI-RS triggered by DCI.

[0121] 53) The scheduling type of the first downlink transmission is configuration transmission, such as semi-static downlink transmission, and the scheduling type of the first uplink transmission is dynamic scheduling, such as DCI format. For example, the first uplink transmission can be a PUSCH scheduled by DCI 0_0, DCI 1_0, DCI 2_0, etc., or a PUCCH carrying HARQ-ACK scheduled by the corresponding DCI, or an SRS triggered by DCI, etc.

[0123] DG overrides CG

[0124] Assume that in a certain time unit, the terminal activates or enables the first mode, and is configured or scheduled for the first downlink transmission and the first uplink transmission, wherein the first downlink transmission is a semi-statically configured downlink transmission, such as SSB, SPS downlink transmission, CSI-RS, etc., and the first uplink transmission is a dynamically scheduled uplink transmission; or the first uplink transmission is a semi-statically configured uplink transmission, and the first downlink transmission is a dynamically scheduled downlink transmission. For simplicity, the dynamically scheduled downlink transmission or uplink transmission is collectively referred to as DG, and the semi-statically configured downlink transmission or uplink transmission is collectively referred to as CG.

[0125] Among them, if the first uplink transmission and the first downlink transmission also meet the target situation, wherein the target situation includes at least one of the following 61)-63).

[0126] 61) The first uplink transmission and the first downlink transmission overlap in time domain;

[0127] 62) The time domain interval between the first uplink transmission and the first downlink transmission is less than a first threshold, such as TI;

[0128] 63) The first uplink transmission and the first downlink transmission are located in the same time unit, such as a time slot or a sub-time slot.

[0129] Based on this, the terminal may obtain the transmission power Px or power spectrum density Py of the first uplink transmission according to the transmission parameters corresponding to the first mode.

[0130] Among them, the way in which the terminal performs the first uplink and the first downlink transmission includes what is shown in the following 71)-72).

[0131] 71) If Px is greater than or equal to a certain threshold value Pt, or Py is greater than or equal to a certain threshold value Pm, the terminal determines to perform the first uplink transmission and the first downlink transmission in a second manner. For example, if the dynamic scheduling is the first downlink transmission, the terminal receives the first downlink transmission and cancels the first uplink transmission; if the dynamic scheduling is the first uplink transmission, the terminal cancels the first downlink transmission and performs the first uplink transmission.

[0132] Optionally, when the terminal performs the first uplink transmission or the first downlink transmission, the terminal determines the transmission parameters of the corresponding transmission, such as transmission power, transmission time-frequency resources, etc., according to the transmission parameters corresponding to the second method.

[0133] 72) If Px is less than or equal to a certain threshold value Pt, or Py is less than a certain threshold value Pm, the terminal transmits in a first manner, such as transmitting the first uplink transmission and the first downlink transmission simultaneously.

[0134] Among them, when the terminal performs the first uplink transmission or the first downlink transmission, the terminal determines the transmission parameters of the corresponding transmission according to the transmission parameters corresponding to the first method, such as transmission power, transmission time-frequency resources, etc.

[0135] It is worth noting that at this time, the frequency domain interval between the first downlink transmission and the first uplink transmission meets a certain threshold gap1 requirement, such as being greater than or equal to a fourth threshold, so that the first downlink transmission and the first uplink transmission are non-overlapping. The fourth threshold is a non-negative value, which can be configured / indicated by the base station or determined according to a predefined rule.

[0136] Otherwise, if the frequency domain interval between the first downlink transmission and the uplink transmission does not meet a certain threshold requirement, such as being less than a fourth threshold, the terminal transmits in accordance with the second method, or the terminal performs the first downlink transmission or the first uplink transmission according to the rate-matching or puncture part of the frequency domain resources until the frequency domain interval requirement is met, and transmits in accordance with the first method.

For simplicity, they are referred to as DG1 and DG2 here respectively.

[0140] Among them, if the first uplink transmission and the first downlink transmission also meet the target situation, wherein the target situation includes at least one of the following 81)-83).

[0143] 83) The first uplink transmission and the first downlink transmission are located in the same time unit, such as a time slot or a sub-time slot.

[0144] Optionally, the above DG1 and DG2 correspond to different priorities, such as physical layer priority or protocol specification (for example, the priority of PDCCH ordered PRACH is higher than that of Dynamic PDSCH. Optionally, the priority of DG2 is higher than that of DG1. The terminal does not expect the above scenario to occur between DGs of the same priority.

[0145] Then, the terminal may obtain the transmission power Px or power spectrum density Py of the first uplink transmission according to the transmission parameters corresponding to the first mode.

[0146] Among them, the way in which the terminal performs the first uplink and the first downlink transmission includes what is shown in the following 91)-92).

[0147] 91) If Px is greater than or equal to a certain threshold value Pt, or Py is greater than or equal to a certain threshold value Pm, the terminal operates in the second mode for transmission.

[0148] For example, the terminal performs the first uplink transmission or the first downlink transmission according to a transmission scheduling time, wherein, in the case of DCI scheduling, the transmission scheduling time is determined according to the start / end symbol of the PDCCH or CORESET where the DCI is located.

[0149] Alternatively, the terminal performs a high-priority transmission among the first uplink transmission and the first downlink transmission, and cancels a low-priority transmission.

[0150] Alternatively, the terminal performs a first uplink transmission.

[0151] Alternatively, the terminal performs a first downlink transmission.

[0152] Alternatively, the terminal determines according to the transmission signal type, for example, if the first uplink transmission is PRACH, then the first uplink transmission is performed; for another example, if the first downlink transmission is SSB or CSI-RS, then the first downlink transmission is performed.

[0155] Among them, when the terminal performs the first uplink transmission and the first downlink transmission, the terminal determines the transmission parameters of the corresponding transmission according to the transmission parameters corresponding to the first method, such as transmission power, transmission time-frequency resources, etc.

[0156] It is worth noting that at this time, the frequency domain interval between the first downlink transmission and the first uplink transmission meets a certain threshold gap1 requirement, such as being greater than or equal to a fourth threshold, so that the first downlink transmission and the first uplink transmission are non-overlapping. The fourth threshold is a non-negative value, which can be configured / indicated by the base station or determined according to a predefined rule.

[0157] Otherwise, if the frequency domain interval between the first downlink transmission and the uplink transmission does not meet a certain threshold requirement, such as being less than a fourth threshold, the terminal transmits in accordance with the second method, or the terminal performs the first downlink transmission or the first uplink transmission according to the rate-matching or puncture part of the frequency domain resources until the frequency domain interval requirement is met, and transmits in accordance with the first method.
