In order to better understand the technical solution of this application, the following contents are first introduced:

Multiplexing of Physical Uplink Control Channel (PUCCH) and PUCCH or PUCCH and Physical Uplink Shared Channel (PUSCH);

Uplink control information (UCI) is mainly transmitted on the uplink control channel (PUCCH). Uplink data is transmitted on the uplink data channel (PUSCH). Due to different starting symbols and symbol lengths, there may be temporal overlap between different PUCCHs or between PUCCH and PUSCH. In principle, PUCCH and PUSCH can be sent at the same time, that is, UCI is retained on PUCCH. However, this will increase the cubic metric; in addition, if the requirements for out-of-band transmission are to be met at a higher transmit power, and the interval in the frequency domain is large when PUSCH and PUCCH are transmitted simultaneously (PUCCH is generally sent at both ends of the frequency band), this will bring challenges to the implementation of Radio Frequency (RF). Therefore, under normal circumstances, if the PUCCHs that need to transmit UCI are multiplexed when the time domain resources overlap, or the PUCCH resources of the UCI that needs to be transmitted are multiplexed when they overlap with the resources of the PUSCH in time, and the base station will ensure that the UCI multiplexing processing time conditions are met when scheduling the PUCCH/PUSCH, UCI will be multiplexed on one PUCCH or UCI and data will be multiplexed on PUSCH to avoid sending different PUCCHs at the same time or avoid sending PUCCH and PUSCH at the same time.

In a PUCCH group, there may be multiple PUCCHs overlapping each other, a PUCCH may also overlap with multiple PUSCHs, or a PUSCH may overlap with multiple PUCCHs. In order to solve the problem of time domain resource overlap between multiple uplink transmission channels, NR 15 defines the processing order of UE uplink multiplexing, specifically:

1) In a time unit, if there are multiple PUCCHs and at least two PUCCHs overlap with each other, the UE first resolves the overlap between PUCCHs and then obtains at most two non-overlapping PUCCHs;

2) For a certain PUCCH outputted in 1), if the PUCCH does not overlap with the PUSCH, the UE transmits the PUCCH. If the PUCCH overlaps with the PUSCH, the UE multiplexes the UCI (excluding the Scheduling Request (SR)) carried by the PUCCH on a certain overlapping PUSCH for transmission according to certain rules. If the PUCCH overlaps with only one PUSCH, the UCI (excluding the SR) is multiplexed on the PUSCH. If the PUCCH overlaps with only multiple PUSCHs, the UE selects a PUSCH for multiplexing according to the corresponding rules. The rules are as follows:

a) First priority: PUSCH with aperiodic channel state information (A-CSI);

b) Second priority: PUSCH with the earliest starting time slot;

c) Third priority: dynamically scheduled PUSCH > configured grant PUSCH or semi-persistent PUSCH;

d) Fourth priority: PUSCH with a smaller serving cell index > PUSCH with a larger serving cell index;

e) Fifth priority: PUSCH with early transmission > PUSCH with late transmission; that is, UE gives priority to PUSCH with A-CSI multiplexing UCI. If there are multiple A-CSI PUSCHs or no A-CSI PUSCHs, for example, there is no A-CSI PUSCH, then UE gives priority to PUSCH with the earliest starting time slot multiplexing UCI among multiple PUSCHs without A-CSI. If there are multiple PUSCHs with the earliest starting time slot, the dynamically scheduled PUSCH is given priority, followed by the configured authorized PUSCH or semi-persistent PUSCH. According to the above rules, if there are still multiple PUSCHs, for example, there are multiple dynamically scheduled PUSCHs, or there are multiple configured authorized PUSCHs or semi-persistent PUSCHs, the PUSCH with the smallest serving cell index is selected. Similarly, if there are multiple PUSCHs with the smallest serving cell index, the PUSCH with the earliest transmission time (starting symbol in the time slot) is selected.

In NR16, in order to better support different services, a 2-level physical layer priority is introduced, where the high and low priorities correspond to priority indexes 1 and 0, respectively. At this time, for the overlapping uplink channels in a time slot, the UE first handles the overlap between channels with the same priority in the manner described in R15, and then handles the overlap between channels with different priorities, where the UE discards the low-priority channel and transmits the high-priority channel.

In NR R17, in order to reduce the impact on low-priority Hybrid automatic repeat request acknowledgment (HARQ-ACK), PUCCH/PUSCH multiplexing between different priorities is also supported. At this time, the UE first handles the overlap between channels of the same priority, and then handles the overlap between channels of different priorities. The specific steps are as follows:

Step 1: Handle overlaps between groups with the same priority level;

Step 1-1: Handle the overlap of PUCCH and PUCCH of the same priority;

Step 1-2: Handle the overlap of PUCCH and PUSCH of the same priority;

Step 2: Deal with overlaps between different priorities;

Step 2-1: Handle the overlap of PUCCHs with different priorities;

Step 2-2: Handle the overlap of PUCCH and PUSCH of different priorities;

In step 2-2, for the overlap of low priority (LP) PUSCH and high priority (HP) PUCCH with positive SR, the UE discards the LP PUSCH. The UE first performs the discard operation and then performs the multiplexing operation of PUCCH and PUSCH. A PUSCH is selected according to the method in R15 to multiplex the UCI carried by the PUCCH. As a result, the terminal can multiplex the low priority HARQ-ACK on the high priority PUSCH, or multiplex the high priority HARQ-ACK on the low priority PUSCH.

Subband non-overlapping Full duplex

Sub-band non-overlapping full-duplex can improve transmission delay and enhance coverage.

Referring to Figures 1b and 1c, for a downlink (DL) time slot (which can be configured by the base station through high-level signaling such as time slot configuration parameters), the network configures a DL bandwidth part (Bandwidth Part, BWP) for the UE. For uplink (UL) slots, the network configures UL BWP for the UE. For example, time slot 1 is a DL slot and time slot 4 is a UL slot;

For full duplex scenarios, there are three cases:

case 1: Configure DL BWP, such as slot 1;

Case 2: Configure DL BWP and UL sub-band, such as slot 2;

case 3: configure UL BWP and DL sub band, such as slot 3;

For a UL slot (configured by the parameters mentioned above):

case 4: Configure UL BWP, such as slot 4;

case 5: configure UL BWP and UL sub band, such as slot5;

case 6: Configure DL BWP and DL sub band, such as slot 6;

For subband full-duplex (SBFD) operation, an SBFD subband consists of one RB or a set of consecutive RBs with the same transmission direction.

The time unit (e.g., time slot or symbol) in which the gNB uses SBFD operation may be referred to as a SBFD time unit (e.g., time slot or symbol).

The transmission method provided in the embodiment of the present application is described in detail below through some embodiments and their application scenarios in combination with the accompanying drawings.

Referring to FIG. 2 , an embodiment of the present application provides a transmission method, the execution subject of the method is a terminal, and the method includes:

Step 201: When the time domain resources of a PUCCH and one or more PUSCHs overlap, the terminal carries UCI on the PUCCH for transmission, or multiplexes UCI on the target PUSCH in one or more PUSCHs for transmission according to the relationship between the time domain positions of the PUCCH and one or more PUSCHs and the full-duplex time domain unit;

Alternatively, the terminal transmits the PUCCH or PUSCH according to the relationship between the time domain position of the PUCCH or PUSCH and the full-duplex time domain unit.

In an embodiment of the present application, the terminal carries UCI on the PUCCH for transmission according to the relationship between the time domain positions of the PUCCH and one or more PUSCHs and the full-duplex time domain unit, or multiplexes UCI on the target PUSCH in one or more PUSCHs for transmission, or the terminal transmits the PUCCH or the PUSCH according to the relationship between the time domain positions of the PUCCH or PUSCH and the full-duplex time domain unit. This clarifies how a terminal supporting full duplex transmits UCI and PUCCH or PUSCH by channel multiplexing, thereby improving the effectiveness and reliability of the communication system.

It should be noted that there may be one or more PUCCHs in the technical scenario applicable to the embodiments of the present application. The above-mentioned scenario where a PUCCH and a PUSCH overlap means that if there are multiple PUCCHs, each PUCCH can use the method of the embodiments of the present application to determine channel multiplexing.

It should be noted that the full-duplex in the embodiment of the present application refers to full-duplex on the terminal side (it can be understood that if full-duplex is applied on the UE side, full-duplex is also applied on the network side), for example, SBFD, the terminal simultaneously performs uplink transmission and downlink reception on different frequency domain resources at the same time. It can also be FD with overlapping frequency domains, and the terminal simultaneously performs uplink transmission and downlink reception at the same time.

In a possible implementation manner, the full-duplex time domain unit includes one or more of the following:

(1) The network side is configured as a full-duplex time domain unit through the high layer;

(2) The network side dynamically indicates that the time domain unit is full-duplex;

(3) A time domain unit that is scheduled or configured to perform uplink transmission and downlink reception simultaneously.

In a possible implementation manner, the terminal multiplexes the UCI on a target PUSCH in one or more PUSCHs for transmission according to the time domain positions of the PUCCH and one or more PUSCHs, including:

The terminal preferentially multiplexes the UCI for transmission on a PUSCH whose time domain position does not overlap with the full-duplex time domain unit.

In an embodiment of the present application, the UE preferentially multiplexes the UCI onto the PUSCH whose time domain position does not overlap with the full-duplex time unit, so as to avoid full-duplex self-interference and prevent adverse effects on UCI transmission.

In a possible implementation manner, the priority order in which the terminal multiplexes UCI on the PUSCH satisfies:

The PUSCH whose time domain position does not overlap with the full-duplex time domain unit has the highest priority;

In all PUSCHs whose time domain positions do not overlap with the full-duplex time domain unit, or in all PUSCHs whose time domain positions overlap with the full-duplex time domain unit, the priority order from high to low meets the following requirements:

PUSCH carrying A-CSI;

The earliest PUSCH in the starting time slot;

Dynamically scheduled PUSCH;

Configure authorized PUSCH or semi-static PUSCH;

The PUSCH with a smaller serving cell index is given priority.

The PUSCH that is transmitted earlier, that is, the PUSCH that is transmitted earlier, has higher priority.

In the embodiment of the present application, the priority of the PUSCH whose time domain position does not overlap with the full-duplex time domain unit is set to the highest; and for the situation where it is impossible to sort only by whether it overlaps with the full-duplex time domain unit, for example, there are multiple PUSCH time domain positions that do not overlap with the full-duplex time domain unit, or all PUSCH time domain positions overlap with the full-duplex time domain unit. For all PUSCHs whose time domain positions do not overlap with the full-duplex time domain unit, or all PUSCHs whose time domain positions overlap with the full-duplex time domain unit, the priority order from high to low satisfies: PUSCH carrying A-CSI>PUSCH with the earliest starting time slot>PUSCH with dynamic scheduling>PUSCH with configuration authorization or semi-static PUSCH>PUSCH with a smaller serving cell index>PUSCH transmitted earlier;

Optional, in the following order of precedence:

a) Priority 0: PUSCH whose time domain location does not overlap with the full-duplex time unit;

b) First priority: PUSCH with A-CSI;

c) Second priority: PUSCH with the earliest starting time slot;

d) Third priority: dynamically scheduled PUSCH> configured authorized PUSCH or semi-Persistent PUSCH;

e) Fourth priority: PUSCH with smaller serving cell index > PUSCH with larger serving cell index;

f) Fifth priority: PUSCH with early transmission > PUSCH with late transmission;

The terminal multiplexes UCI on the PUSCH according to the priority order of a) to f) above.

In a possible implementation manner, the terminal multiplexes the UCI on the PUSCH in a priority order from high to low that satisfies:

PUSCH carrying A-CSI;

PUSCH whose time domain location does not overlap with the full-duplex time domain unit;

In all PUSCHs whose time domain positions do not overlap with the full-duplex time domain unit, or in all PUSCHs whose time domain positions overlap with the full-duplex time domain unit, the priority order from high to low meets the following requirements:

The earliest PUSCH in the starting time slot;

Dynamically scheduled PUSCH;

Configure authorized PUSCH or semi-static PUSCH;

PUSCH with a smaller serving cell index;

Transmit earlier PUSCH.

In the embodiment of the present application, the PUSCH carrying A-CSI is ranked the highest; followed by the PUSCH whose time domain position does not overlap with the full-duplex time domain unit. For the case where it is impossible to sort only by whether it overlaps with the full-duplex time domain unit, that is, there are multiple PUSCHs whose time domain positions do not overlap with the full-duplex time domain unit, or all PUSCHs overlap with the full-duplex time domain unit, then the priority order from high to low in the PUSCHs whose time domain positions do not overlap with the full-duplex time domain unit or the PUSCHs whose time domain positions overlap with the full-duplex time domain unit satisfies: the earliest PUSCH in the starting time slot> the dynamically scheduled PUSCH> the configured authorized PUSCH or the semi-static PUSCH> the PUSCH with a smaller serving cell index> the PUSCH transmitted earlier;

Optional, in the following order of precedence:

a) First priority: PUSCH with A-CSI;

b) Second priority: PUSCH whose time domain location does not overlap with the full-duplex time unit;

c) Third priority: PUSCH with the earliest starting time slot;

d) Fourth priority: dynamically scheduled PUSCH > configured authorized PUSCH or semi-Persistent PUSCH;

e) Fifth priority: PUSCH with smaller serving cell index > PUSCH with larger serving cell index;

f) Sixth priority: PUSCH with early transmission > PUSCH with late transmission;

The terminal multiplexes the UCI on the PUSCH according to the priority order of a) to f) above.

In a possible implementation manner, the priority order in which the terminal multiplexes UCI on the PUSCH satisfies any one of the following:

PUSCH carrying A-CSI;

The earliest PUSCH in the starting time slot;

Dynamically scheduled PUSCH;

Configure authorized PUSCH or semi-static PUSCH;

PUSCH whose time domain location does not overlap with the full-duplex time domain unit;

In all PUSCHs whose time domain positions do not overlap with the full-duplex time domain unit, or in all PUSCHs whose time domain positions overlap with the full-duplex time domain unit, the priority order from high to low meets the following requirements:

PUSCH with a smaller serving cell index;

Transmit earlier PUSCH.

In the embodiment of the present application, the PUSCH carrying A-CSI is the highest; followed by the PUSCH with the earliest starting time slot; the dynamically scheduled PUSCH; the configured authorized PUSCH or the semi-static PUSCH; and then the PUSCH whose time domain position does not overlap with the full-duplex time domain unit. For the case where it is impossible to sort only by whether it overlaps with the full-duplex time domain unit, that is, there are multiple PUSCHs whose time domain positions do not overlap with the full-duplex time domain unit, or all PUSCHs overlap with the full-duplex time domain unit, then in the PUSCHs whose time domain positions do not overlap with the full-duplex time domain unit or the PUSCHs whose time domain positions overlap with the full-duplex time domain unit, the priority order from high to low satisfies: the PUSCH with a smaller serving cell index> the PUSCH transmitted earlier;

Optional, in the following order of precedence:

a) First priority: PUSCH with A-CSI;

b) Second priority: PUSCH with the earliest starting time slot;

c) Third priority: dynamically scheduled PUSCH > configured authorized PUSCH or semi Persistent PUSCH;

d) Fourth priority: PUSCH whose time domain location does not overlap with the full-duplex time unit;

e) Fifth priority: PUSCH with smaller serving cell index > PUSCH with larger serving cell index;

f) Sixth priority: PUSCH with early transmission > PUSCH with late transmission;

In a possible implementation manner, the terminal carries the UCI on the PUCCH for transmission according to the time domain positions of the PUCCH and one or more PUSCHs, including:

When the time domain position of the PUCCH does not overlap with the full-duplex time domain unit, and the time domain position of each PUSCH overlaps with the full-duplex time domain unit, the UCI is carried on the PUCCH for transmission, and the PUSCH transmission is canceled.

In the embodiment of the present application, if the time domain position of the PUCCH does not overlap with the full-duplex time unit, and the time domain position of each of the PUSCH overlaps with the full-duplex time unit, the PUCCH is transmitted and the PUSCH transmission is canceled. Otherwise, the PUSCH is selected for multiplexing according to the priority order of the terminal to multiplex the UCI on the PUSCH.

In a possible implementation manner, the PUCCH carries HARQ-ACK information and/or channel state information CSI, and the method further includes:

When SR information is also carried in PUCCH, the terminal discards the SR information and multiplexes HARQ-ACK and/or CSI on the target PUSCH. SR is used to request uplink resources. If the UE has PUSCH, it does not need to use SR to request uplink resources. The UE can transmit a Buffer Status Report (BSR) on PUSCH to request uplink resources. BSR can carry more information than SR.

In a possible implementation, the method further includes one or more of the following:

(1) When PUCCH or PUSCH overlaps with one or more of the semi-static DL symbols, the synchronization signal block (SSB) symbols, the DL symbols indicated by the slot format indicator (SFI), and the dynamically scheduled DL transmission, and the overlapping time domain resources are all full-duplex time domain units, the terminal performs uplink transmission and/or downlink reception;

After uplink transmission multiplexing (such as PUCCH and PUCCH, PUCCH and PUSCH), the UE determines the multiplexed uplink transmission (this is an optional step. If there is no overlap between PUCCH and PUCCH or PUSCH and PUSCH, this step does not need to be performed), and determines whether the uplink transmission is consistent with the semi-static DL symbol (for example, Whether the uplink transmission is performed is determined based on whether at least one of the DL symbols configured by tdd-UL-DL-ConfigurationCommon and or tdd-UL-DL-ConfigurationDedicated), SSB symbols, DL symbols indicated by SFI, and dynamically scheduled DL transmissions (e.g., PDCCH or downlink transmissions scheduled by PDCCH, such as PDSCH or CSI-RS) conflicts. If all conflicting resources are FD time units, the UE transmits UL and receives downlink (if any);

Further, the terminal performs uplink sending and/or downlink receiving, including:

The terminal does not consider the preset time interval when performing uplink transmission and/or downlink reception. That is, the terminal does not need to consider the time interval (timeline) when performing uplink transmission and/or downlink reception. For example, the timeline is the time interval between the end symbol (last symbol) of the control resource set (Control Resource Set, CORESET) where the DCI corresponding to the dynamically scheduled DL transmission (such as DCI indicating the UE's reception of PDSCH or CSI-RS) is located and the starting position (first symbol) of the overlapping time domain resources or to the starting symbol position of the uplink transmission is greater than or equal to a certain threshold. The threshold can be determined according to a predefined rule. For example, the threshold can be related to factors such as UE capability, downlink transmission or uplink transmission subcarrier spacing, etc.

(2) When PUCCH or PUSCH overlaps with one or more of the semi-static DL symbols, SSB symbols, DL symbols indicated by SFI, and dynamically scheduled DL transmissions in time domain resources, and the preset time interval is not met, the terminal does not expect the symbols overlapping the uplink and downlink transmissions to contain non-full-duplex time domain units;

If the timeline is not satisfied, the UE does not expect the symbols overlapped by uplink and downlink transmission to be non-FD symbols.

(3) When PUCCH or PUSCH overlaps with one or more of the semi-static DL symbols, SSB symbols, DL symbols indicated by SFI, and dynamically scheduled DL transmissions in time domain resources, and the overlapping time domain resources are not all full-duplex time domain units, the terminal discards or cancels the transmission of PUCCH or PUSCH.

If the conflicting resources are not all FD time domain units, the UE discards the above uplink transmission, or the multiplexed uplink transmission.

Furthermore, for dynamically scheduled DL transmission, the corresponding timeline needs to be met.

The technical solution of the present application is described below in conjunction with specific embodiments:

Embodiment 1:

Method 1: The UE determines which PUSCH to multiplex the UCI on for transmission based on whether the time domain positions of the PUCCH and PUSCH overlap with the full-duplex time unit. Specifically,

The UE preferentially multiplexes the UCI onto the PUSCH whose time domain position does not overlap with the full-duplex time unit;

The above criteria can be combined with existing criteria, such as 1;

a) Priority 0: PUSCH whose time domain location does not overlap with the full-duplex time unit;

b) First priority: PUSCH with A-CSI;

c) Second priority: PUSCH with the earliest starting time slot;

d) Third priority: dynamically scheduled PUSCH> configured authorized PUSCH or semi-Persistent PUSCH (semi-persistent PUSCH, such as PUSCH configured by the parameter semiPersistentOnPUSCH);

e) Fourth priority: PUSCH with smaller serving cell index > PUSCH with larger serving cell index;

f) Fifth priority: PUSCH with early transmission > PUSCH with late transmission;

Assume that the full-duplex time unit is based on high-level configuration (such as system information and/or radio resource control (Radio The full-duplex time unit determined by Resource Control (RRC)).

As shown in Figure 3a, it is assumed that the FD configuration of all service cells is as shown in Figure 3a, that is, the first 7 symbols in a time slot are FD symbols, and the last 7 symbols are non-FD symbols. Assume that PUCCH is a PUCCH carrying HARQ-ACK and/or CSI, PUSCH is a PUSCH without A-CSI scheduled by DCI, and the starting time slot of all PUSCH is the same. According to the above method, the UE preferentially selects the PUSCH whose time domain resources do not overlap with the full-duplex symbol to multiplex the UCI carried by the PUCCH. Therefore, the UE preferentially selects between PUSCH2 and PUSCH3, and then according to the above method, the UE selects the PUSCH with a smaller index in the service cell, that is, PUSCH2 for multiplexing.

Example 2

a) First priority: PUSCH with A-CSI;

b) Second priority: PUSCH whose time domain location does not overlap with the full-duplex time unit;

c) Third priority: PUSCH with the earliest starting time slot;

d) Fourth priority: dynamically scheduled PUSCH> configured authorized PUSCH or semi-Persistent PUSCH;

e) Fifth priority: PUSCH with smaller serving cell index > PUSCH with larger serving cell index;

f) Sixth priority: PUSCH with early transmission > PUSCH with late transmission;

In Figure 3a, it is assumed that PUSCH1 is a PUSCH containing A-CSI. According to the above method, the UE preferentially selects the PUSCH with A-CSI. If there is no PUSCH with A-CSI, the PUSCH is selected according to other principles. In the above figure, the UE selects PUSCH1 multiplexing the UCI carried by PUCCH.

Example 3

a) First priority: PUSCH with A-CSI;

b) Second priority: PUSCH with the earliest starting time slot;

c) Third priority: dynamically scheduled PUSCH > configured authorized PUSCH or semi-PersistentPUSCH;

d) Fourth priority: PUSCH whose time domain location does not overlap with the full-duplex time unit;

e) Fifth priority: PUSCH with smaller serving cell index > PUSCH with larger serving cell index;

f) Sixth priority: PUSCH with early transmission > PUSCH with late transmission;

As shown in Figure 3b, UE-side full-duplex is configured on PCell, SCell1, and SCell2, and their FD time domain resource configuration is shown in the figure. UE-side full-duplex is not configured on SCell3. The FD configurations on PCell, SCell1, and SCell2 are the same, as shown in Figure 3a, that is, the first 7 symbols in a time slot are FD symbols, and the last 7 symbols are non-FD symbols. Assume that PUCCH is a PUCCH carrying HARQ-ACK and/or CSI, and PUSCH is a DCI-scheduled PUSCH without A-CSI. And the starting time slots of all PUSCHs are the same. According to the above method, since there is no PUSCH with A-CSI and the starting time slots of PUSCH are the same, and they are all dynamically scheduled, the UE gives priority to PUSCHs whose time domain positions do not overlap with the full-duplex time unit, namely PUSCH2 and PUSCH3. Then, PUSCH2 and PUSCH3 select the PUSCH with a smaller serving cell index.

Embodiment 2:

In the prior art, for a half-duplex UE, the UE first performs multiplexing operations between different uplink channels (such as PUCCH and PUCCH, PUCCH and PUSCH), and then determines whether the multiplexed channel resources are consistent with the downlink semi-static DL symbol Or the downlink transmission or SSB conflicts with the dynamically scheduled DL transmission (time domain resource overlap). If the multiplexed uplink transmission resource conflicts with the downlink semi-static DL symbol or the downlink transmission or SSB, the UE cancels the uplink transmission. If the multiplexed uplink transmission resource conflicts with the dynamically scheduled DL transmission and meets the corresponding timeline requirements (for example, the interval from the end position of the DCI corresponding to the DL transmission to the start position of the UL transmission or the first overlapping symbol is greater than a certain value), the UE cancels the uplink transmission.

For full-duplex UE, after performing multiplexing operations between different uplink channels (such as PUCCH and PUCCH, PUCCH and PUSCH), the UE determines whether the multiplexed channel resources (if there is no overlap, no multiplexing operation is required, here is the uplink transmission to be transmitted) conflict with the downlink semi-static DL symbol or downlink transmission or SSB or dynamically scheduled DL transmission, including at least one of the following:

If all conflicting resources are FD time units, the UE transmits UL and receives downlink (if any), and does not need to consider whether the corresponding timeline is met.

If the corresponding timeline is not met, UE does not expect any symbol with overlapped DL/UL transmission is not within FD symbol(s).

If the conflicting resources are not all FD time units, the UE discards the multiplexed uplink transmission.

If the conflicting resources are not all FD time units, when the dynamically scheduled DL transmission conflicts with the uplink transmission, the UE discards the multiplexed uplink transmission if the corresponding timeline is met.

The FD time unit, i.e., the full-duplex time domain unit, includes one or more of the following:

(1) The network side is configured as a full-duplex time domain unit through the high layer;

(2) The network side dynamically indicates that the time domain unit is full-duplex;

(3) A time domain unit that is scheduled or configured to perform uplink transmission and downlink reception simultaneously.

Embodiment three:

The full-duplex time domain unit in the present application may be determined based on high-level parameters, for example, the base station configures which time slots/symbols are FD time slots/symbols (indicating that the base station can schedule UEs for uplink transmission and downlink reception on these time slots/symbols at the same time) through system messages or RRC parameters or medium access control control parameters (Medium Access Control Control Element, MAC CE), and these FD time slots/symbols configured by the high-level are the full-duplex time units in the present application. Alternatively, the UE indicates to the UE which time slots/symbols are FD time slots/symbols (indicating that the base station can schedule UEs for uplink transmission and downlink reception on these time slots/symbols at the same time) based on high-level configuration and dynamic indication (such as group common DCI) or other non-scheduled DCI, for example, the base station first configures which time slots/symbols are flexible/unknown time slots/symbols (indicating that the symbol can be either half-duplex time slots/symbols or full-duplex time slots/symbols) through high-level signaling, and then the base station indicates through dynamic indication whether the flexible/unknown time slots/symbols are half-duplex time slots/symbols or full-duplex time slots/symbols. The full-duplex time slot/symbol dynamically indicated at this time is the full-duplex time unit in this application.

Alternatively, the full-duplex time unit in the present application is a time unit in which the UE is scheduled to perform uplink transmission and downlink reception simultaneously in the time unit (for example, some time slots/symbols are configured as FD time slots/symbols by the base station, but the UE is not scheduled to transmit and receive simultaneously in these time slots/symbols, which does not belong to the full-duplex time unit in the present application)
