[0029] The technical solutions provided by the embodiments of the present application are described in detail below through some embodiments and their application scenarios in conjunction with the accompanying drawings.
[0030] FIG2 is a flow chart of a transmission method 200 provided in an exemplary embodiment of the present application. The method 200 may be, but is not limited to, executed by a terminal, specifically by hardware or software installed in the terminal. In this embodiment, the method 200 may include at least the following steps.
[0031] 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 target conditions, the terminal obtains target information.
[0032] The target situation may include but is not limited to at least one of the following 11)-13).
[0033] 11) The first uplink transmission and the first downlink transmission overlap in the time domain.
[0034] The first uplink transmission and the first downlink transmission may partially overlap or completely overlap in the time domain, which is not limited here.
[0035] 12) A time domain interval between the first uplink transmission and the first downlink transmission is less than a first threshold.
[0036] 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.
[0037] 13) The first uplink transmission and the first downlink transmission are in the same time unit.
[0038] The time unit may be a time slot, a sub-time slot, a symbol, or a symbol set, etc., which is not limited here.
[0039] 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-layer 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, there may be a problem that the first uplink transmission interferes with the first downlink transmission. 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.
[0040] In this regard, the present application takes into account that when the terminal operates 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. Thus, 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 resource utilization; on the other hand, it can also avoid the problem of reserving more resources for transmit and receive isolation in order to solve the transmission self-interference in the related technology, thereby reducing resource utilization, thereby improving the performance of the communication system.
[0041] Optionally, considering that the target information is related to the transmission power of the terminal, in this embodiment, the target information can be the transmission power, power spectrum density (PSD), etc. of the first uplink transmission, or it can be 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 there is no limitation here.
[0042] In addition, the second method may include but is not limited to at least one of the following 21)-22).
[0043] 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.
[0044] 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 or downlink transmission at the same time, while the network side can perform uplink and downlink transmission at the same time.
[0045] S220: Determine, according to the target information, whether to perform the first uplink transmission or the first downlink transmission based on a first manner or a second manner.
[0046] In this embodiment, depending on the 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.
[0047] 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 based on 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.
[0048] FIG3a is a flow chart of a transmission method 300 provided in an exemplary embodiment of the present application. The method 300 may be, but is not limited to, executed by a terminal, specifically by hardware or software installed in the terminal. In this embodiment, the method 300 may include at least the following steps.
[0049] 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 target conditions, the terminal obtains target information.
[0050] 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 the 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.
[0051] It is 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 effects. Of course, in addition to referring to the relevant description in the aforementioned method embodiment 200, as a possible implementation method, as shown in Figure 3a, taking the terminal's autonomous determination as an example, the implementation process of S310 can include S311, the content of which is as follows.
[0052] S311: 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 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.
[0053] 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 parameters such as transmission bandwidth, frequency hopping pattern, PUCCH resource configuration, CG PUSCH configuration, etc. In this embodiment, the transmission parameters corresponding to the first method can be implemented by protocol agreement, high-level configuration, etc., and are not limited here.
[0054] 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.
[0055] Based on this, in some embodiments, the target information may include but is not limited to at least one of the following 31)-34).
[0056] 31) Transmission power of the first uplink transmission.
[0057] 32) Power spectral density of the first uplink transmission.
[0058] 33) The difference between the transmission power of the first uplink transmission and the reception power of the second downlink transmission.
[0059] 34) A difference between the power spectral density of the first uplink transmission and the power spectral density of the second downlink transmission.
[0060] In this embodiment, the second downlink transmission is received no later than the start time of the first uplink transmission. In other words, the second downlink transmission may be received by the terminal before the start time of the first uplink transmission.
[0061] For example, in this embodiment, the second downlink transmission may be the most recently received downlink transmission by the terminal before the first uplink transmission is sent, or the most recently received downlink transmission by the terminal before a first time. The first time is before the time the first uplink transmission is sent, and the time interval between the first uplink transmission and the first time interval is a first duration. It is understood that the first time and the first duration may be implemented by protocol agreement, high-layer configuration, terminal reporting, or other means.
[0062] 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 the target information determination.
[0063] 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.
[0064] 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.
[0065] 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.
[0066] It is understood that the implementation process of S320 may refer to the relevant description in the aforementioned method embodiment 200 and achieve the same or corresponding technical effects. Of course, in addition to referring to the relevant description in the aforementioned method embodiment 200, as a possible implementation method, depending on 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 to 6.
[0067] 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.
[0068] 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 based on predefined rules.
[0069] For example, when determining the second threshold or the third threshold according to the predefined rule, the second threshold or the third threshold may be related to a transmission parameter of the first uplink transmission, such as different transmission parameters corresponding 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 a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH), etc.
[0070] 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.
[0071] Mode 3: When the difference between the transmission power of the first uplink transmission and the receiving power of the second downlink transmission meets a first condition, the terminal determines to perform the first uplink transmission or the first downlink transmission based on the first mode.
[0072] 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.
[0073] Optionally, the threshold or the value range may be implemented by base station configuration / instruction, terminal reporting, or determination according to predefined rules.
[0074] 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 meets the second condition, the terminal determines to perform the first uplink transmission or the first downlink transmission based on the first mode.
[0075] 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.
[0076] Optionally, the threshold or the value range may be implemented by base station configuration / instruction, terminal reporting, or determination according to predefined rules.
[0077] 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 meet the first condition, the terminal determines to perform the first uplink transmission or the first downlink transmission based on the second mode.
[0078] 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 meet the second condition, the terminal determines to perform the first uplink transmission or the first downlink transmission based on the second mode.
[0079] It is worth noting that, in some implementations, which of the aforementioned modes 1-6 is actually adopted by the terminal may be determined by protocol agreement, high-level configuration / instruction, or according to predefined rules. For example, assuming that the terminal can determine according to predefined rules, the predefined rules may be priority rules between the aforementioned modes 1-6, that is, the terminal may adopt the mode with the higher priority for the first uplink transmission or the first downlink transmission based on the priority order corresponding to the modes 1-6, and this is not limited here.
[0080] 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).
[0081] 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.
[0082] 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.
[0083] 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.
[0084] 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.
[0085] 42) The terminal performs the first uplink transmission and cancels the first downlink transmission.
[0086] For example, the terminal may determine, according to a protocol agreement or other means, that when performing the first uplink transmission or the first downlink transmission based on the second manner, directly perform the first uplink transmission and cancel the first downlink transmission.
[0087] 43) The terminal performs the first downlink transmission and cancels the first uplink transmission.
[0088] For example, the terminal may determine, according to a protocol agreement or other means, that when the first uplink transmission or the first downlink transmission is performed based on the second manner, the first downlink transmission is performed directly and the first uplink transmission is canceled.
[0089] 44) The terminal determines whether to perform the first uplink transmission or the first downlink transmission according to the transmission signal type.
[0090] 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.
[0091] Exemplarily, if the first uplink transmission is the PRACH, the terminal performs the first uplink transmission and delays or cancels the first downlink transmission.
[0092] 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.
[0093] 45) Determining whether to perform the first uplink transmission or the first downlink transmission according to the transmission scheduling type.
[0094] The transmission scheduling type includes 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.
[0095] 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.
[0096] 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.
[0097] 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; 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.
[0098] 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.
[0099] It is worth noting that the terminal may determine to perform the first uplink transmission or the first downlink transmission based on any one of the aforementioned items 41)-46). However, if any one of the aforementioned items 41)-46) cannot determine whether to perform the first uplink transmission or the first downlink transmission, such as if the two items have the same priority, the same transmission signal type, the same scheduling type, or the same transmission start time, then the terminal may independently determine which one to transmit, or may combine two or more of the items 41)-46) to determine whether to perform the first uplink transmission or the first downlink transmission.
[0100] 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 based on a transmission signal type or a scheduling type.
[0101] In some embodiments, when the terminal performs the first uplink transmission or the first downlink transmission based on the second mode, a transmission parameter of the first uplink transmission or the first downlink transmission is determined according to a transmission parameter corresponding to the second mode.
[0102] 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 pre-configured one or more sets of transmission parameters to determine the transmission parameters of the first uplink transmission or the first downlink transmission.
[0103] The transmission parameters corresponding to the second mode may include but are not limited to transmission power, transmission time-frequency resources, MCS, etc.
[0104] 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.
[0105] The frequency domain gap between the first uplink transmission and the first downlink transmission satisfies a requirement of being greater than or equal to a fourth threshold, thereby avoiding overlap or partial overlap between the first uplink transmission and the first downlink transmission, or self-interference caused by the first uplink transmission on the first downlink transmission. Optionally, the fourth threshold is a non-negative value, and may be configured / indicated by a base station or determined according to a predefined rule, which is not limited herein.
[0106] 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).
[0107] 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 is understood that in some embodiments, the terminal is pre-configured with one or more sets of transmission parameters corresponding to the first mode. 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 pre-configured sets of transmission parameters to determine the transmission parameters of the first uplink transmission or the first downlink transmission.
[0108] The transmission parameters corresponding to the first mode may include but are not limited to transmission power, transmission time-frequency resources, MCS, etc.
[0109] In this embodiment, the terminal determines the transmission mode based on information related to transmission power, thereby avoiding transmission interference and improving the effectiveness of the communication system.
[0110] Based on the description of the aforementioned method embodiments 200-300, the transmission method provided in this application is exemplarily described below with reference to examples, as follows.
[0111] Example 1
[0112] As shown in Figure 3b, in a certain time unit, assuming that the terminal activates or enables the first mode, and 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, then the terminal obtains the transmission power Px or power spectrum density Py of the first uplink transmission according to the transmission parameters corresponding to the first mode.
[0113] 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 spectral 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 according to the second manner. Transmission parameters corresponding to the first uplink transmission or the second downlink transmission are determined based on transmission parameters corresponding to the second manner.
[0114] or,
[0115] If the transmission power Px of the first uplink transmission is less than or equal to a second threshold, or the power spectral density Py of the first uplink transmission is less than or equal to a third threshold, performing the first uplink transmission or the first downlink transmission in a first manner, such as transmitting the first uplink transmission or the first downlink transmission simultaneously. Transmission parameters corresponding to the first uplink transmission or the second downlink transmission are determined based on transmission parameters corresponding to the first manner.
[0116] 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 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.
[0117] 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 downlink subband (DL subband) semi-statically configured by the base station through high-layer 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.
[0118] It can be understood that when the terminal performs the first uplink transmission or the first downlink transmission according to the second manner, the frequency domain resources for 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 higher 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.
[0119] It is worth noting that, for the first uplink transmission and the first downlink transmission in this example 1, they may include any one of the following 51)-53).
[0120] 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).
[0121] Optionally, for PDCCH, it may be a PDCCH monitor occasion configured by the terminal, etc.
[0122] 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 (SRS) or semi-persistent SRS (SP-SRS), etc.
[0123] 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. For example, 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.
[0124] 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.

[0127] 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.

[0131] 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.
[0132] 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.
[0133] 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).
[0134] 71) If Px is greater than or equal to a threshold value Pt, or if Py is greater than or equal to a threshold value Pm, the terminal determines to perform the first uplink transmission and the first downlink transmission according to a second method. 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.
[0135] 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.
[0136] 72) If Px is less than or equal to a certain threshold Pt, or Py is less than a certain threshold Pm, the terminal transmits in a first manner, such as transmitting the first uplink transmission and the first downlink transmission simultaneously.
[0137] 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.
[0138] It is worth noting that, at this time, the frequency domain interval between the first downlink transmission and the first uplink transmission satisfies 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 do not overlap. The fourth threshold is a non-negative value, which can be configured / indicated by the base station or determined according to a predefined rule.
[0139] Otherwise, if the frequency domain interval between the first downlink transmission and the uplink transmission does not meet a certain threshold requirement, such as 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 respectively.

[0147] 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.
[0148] 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.
[0149] 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).
[0150] 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.
[0151] For example, the terminal performs the first uplink transmission or the first downlink transmission according to the 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.
[0152] Alternatively, the terminal performs the higher-priority transmission among the first uplink transmission and the first downlink transmission, and cancels the lower-priority transmission.
[0153] Alternatively, the terminal performs a first uplink transmission.
[0154] Alternatively, the terminal performs the first downlink transmission.
[0155] Alternatively, the terminal determines based on 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.
[0156] The transmission parameters of the terminal when performing the first uplink transmission or the first downlink transmission are determined according to the transmission parameters corresponding to the second mode, and the transmission parameters may be transmission power, transmission time-frequency resources, etc.

[0159] It is worth noting that, at this time, the frequency domain interval between the first downlink transmission and the first uplink transmission satisfies 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 do not overlap. The fourth threshold is a non-negative value, which can be configured / indicated by the base station or determined according to a predefined rule.
[0160] Otherwise, if the frequency domain interval between the first downlink transmission and the uplink transmission does not meet a certain threshold requirement, such as 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.
