The method for determining the transmission direction of the resources provided by the embodiment of the invention can be applied to a full duplex/flexible duplex scene, and when the terminal detects that the first resource of the first authorization indication sent by the network side equipment and the second resource of the second authorization indication are partially or completely overlapped, the terminal determines the priority of the first authorization and/or the second authorization based on the characteristic information for indicating the authorization priority, then determines the transmission direction of the first resource and the second resource or the sub-band where the first resource and/or the second authorization are located based on the priority of the first authorization and/or the second authorization, and changes the transmission direction of the resources indicated by the high priority authorization by keeping the transmission direction of the resources indicated by the high priority authorization, and rewrites the transmission direction of the resources indicated by the low priority authorization according to the transmission direction of the resources indicated by the high priority authorization so as to determine the available resources of the low priority authorization indication resources, thereby ensuring the normal transmission of the channel or the signal scheduled by the high priority authorization, and improving the coverage and time delay of the utilization of the resources.

Fig. 2 is a flowchart of a method for determining a transmission direction of a resource according to an embodiment of the present application, as shown in fig. 2, where the method includes steps 201 to 202; wherein:

step 201, when detecting that a first resource of a first authorization instruction sent by a network side device overlaps a second resource of a second authorization instruction, the terminal determines a priority of the first authorization and/or the second authorization based on feature information of the first authorization and feature information of the second authorization.

Step 202, the terminal determines the transmission directions of the first resource and the second resource based on the priority of the first grant and/or the second grant.

It should be noted that the embodiments of the present application may be applied to full duplex/flexible duplex scenarios; the terminals include, but are not limited to, the types of terminals 11 listed above, and the network-side devices include, but are not limited to, the types of network-side devices 12 listed above, to which the embodiments of the present application are not limited. The first grant may indicate that the intended transmission direction of the first resource and the second grant may indicate that the intended transmission direction of the second resource are opposite directions. In practice, the terminal may determine to perform step 201 and step 202 based on at least one of protocol predefining, terminal autonomously determining and informing of the network, higher layer pre-configuration or network configuration.

It is understood that the first resource of the first grant indication overlaps with the second resource of the second grant indication, which means that the time domain and/or frequency domain resource of the first grant indication overlaps with part or all of the time domain and/or frequency domain resource of the second grant indication.

In an embodiment of the present application, the feature information may include at least one of the following:

(1) Receiving time information;

(2) Priority information of the authorization;

(3) Authorization type information; wherein the authorization-type information includes a dynamic indication or a semi-static configuration. In practice, dynamic refers to example downlink control information (Downlink Control Information, DCI) signaling. The semi-static configuration may include at least one of: configuration authorization (configured grant) configuration; semi-permanent persistent scheduling (Semi-Persistent Scheduling, SPS) configuration; scheduling requests (scheduling request, SR); channel state information (Channel State Information, CSI) reporting (report) configuration; sounding reference signal (Sounding Reference Signal, SRS) configuration; coreset configuration; channel state information reference signal (Channel State Information Reference Signal, CSI-RS) configuration.

(4) Authorized bearer resource type information;

specifically, the authorized bearer resource types may include at least one of: the coreset number where the authorization is located; search space set number.

(5) Authorized format information;

(6) Type information of the authorized scrambling;

(7) Grant the type of channel and/or signal scheduled;

(8) Grant scheduled channel and/or retransmission number information of signal.

Optionally, after determining the high priority and the low priority in the first grant and the second grant, the terminal keeps the resource transmission direction indicated by the high priority grant unchanged, rewrites the resource transmission direction indicated by the low priority grant according to the resource transmission direction indicated by the high priority grant, and determines available resources of the resources indicated by the low priority grant.

In the method for determining the transmission direction of the resources provided by the embodiment of the application, when the terminal detects that the first resource of the first authorization indication sent by the network side device and the second resource of the second authorization indication are partially or completely overlapped, the terminal determines the priority of the first authorization and/or the second authorization based on the characteristic information for indicating the priority of the authorization, then determines the transmission direction of the first resource and the second resource or the sub-band where the first authorization and/or the second authorization are located based on the priority of the first authorization and/or the second authorization, and rewrites the transmission direction of the resource of the low priority authorization indication according to the transmission direction of the resource of the high priority authorization indication by keeping the transmission direction of the resource of the high priority authorization indication unchanged, so as to determine the available resource of the low priority authorization indication resource, ensure the normal transmission of the channel or the signal scheduled by the high priority authorization, improve the coverage of the resource utilization and reduce the time delay.

The manner in which the priority of the first grant and/or the second grant is determined in the embodiments of the present application is described below. The implementation manner of determining the priority of the first authorization and/or the second authorization by the terminal based on the characteristic information of the first authorization and the characteristic information of the second authorization may include any one of the following:

mode 1 for the case where the feature information includes reception time information

The terminal determines, based on the reception time information of the first grant and the reception time information of the second grant, a subsequent grant of the reception times of the first grant and the second grant as a high priority, or a preceding grant of the reception times of the first grant and the second grant as a low priority.

Regarding the reception time of the grant, the reception time of the last symbol carrying the grant control channel is referred to, or the reception time of the start symbol carrying the grant is referred to.

For example, the grant whose reception time of the last symbol in the first and second grants is later is determined as a high priority grant, and the grant whose reception time of the last symbol in the first and second grants is earlier is determined as a low priority.

For another example, the grant having a subsequent time of receipt of the start symbol in the first and second grants is determined to be a high priority grant, and the grant having a preceding time of receipt of the start symbol in the first and second grants is determined to be a low priority.

In this embodiment of the present application, the later received grant has a higher priority than the earlier received grant, and the terminal determines the transmission direction (i.e. UL or DL transmission) of the time domain and/or frequency domain resources indicated by the two grants according to the later received grant.

Fig. 3 is one of schematic diagrams of time-frequency domain resource allocation provided in the embodiments of the present application, as shown in fig. 3, at time t1, a terminal receives UL resource of UL grant scheduling slot n; at time t2 (t 1< t 2), the terminal receives a DL resource of DL grant scheduling slot n; DL resources of DL grant schedule partially overlap UL resources of UL grant schedule. Since the reception time t1 of the UL grant is earlier than the reception time t2 of the DL grant, the terminal recognizes: UL grant is low priority, DL grant is high priority.

Mode 2 for the case where the feature information includes authorized priority information

The terminal determines a high priority grant or a low priority grant in the first grant and the second grant based on the priority information of the first grant and the priority information of the second grant.

Optionally, each grant includes indication information, where the indication information is used to indicate priority information of the grant. Specifically, the first grant includes first indication information, where the first indication information is used to indicate priority information of the first grant; and/or the second authorization comprises second indication information, wherein the second indication information is used for indicating the priority information of the second authorization.

In practice, the existing domain in the grant (i.e. the target domain) may be multiplexed, carrying the indication information in the target domain. Specifically, the target domain in the first authorization includes first indication information; and/or the target field in the second grant includes second indication information. The target domain may be based on a combination of at least one existing domain.

Alternatively, a new domain (e.g., a priority indication domain) may be added to the grant, with indication information carried in the priority indication domain. Specifically, the priority indication field in the first grant includes first indication information; and/or the priority indication field in the second grant includes second indication information.

Optionally, the first grant includes N1 bits therein; wherein the N1 bit is used to indicate priority information of the first grant; and N1 is a positive integer. The second grant includes N2 bits; wherein the N2 bits are used to indicate priority information of the second grant; and N2 is a positive integer.

It will be appreciated that when the type of first grant and the second grant are the same, N1 is the same size as N2. For example, when the first grant and the second grant are both DCI commands, N1 and N2 are the same size. In practice, the specific sizes of N1 and N2 may be determined based on predefined or higher-level pre-configured modes of the protocol. In practice, the type of authorization may include at least one of: radio resource control (Radio Resource Control, RRC) signaling; DCI signaling; medium access Control (Medium Access Control, MAC) Control Element (CE) signaling.

Here, the combination cases for the types of the first authorization and the second authorization are respectively described as follows:

the types of the case (1), the first authorization and the second authorization are dynamic indication

Here, the dynamic indication takes DCI signaling as an example, and a priority indication field is introduced into scheduling DCI sent to the terminal by the network side device. Specifically, an extra x bit is introduced into the DCI and is used for indicating an UL-DL resource priority indication domain (called priority indication domain for short); the size of the bit number x is network configurable. For example, the network configuration introduces an extra 1bit in the DCI, 1 representing a high priority, 0 representing a low priority; alternatively, 0 represents a high priority, and 1 represents a low priority. Taking the example that the priority indication field indication 1 indicates a high priority and the priority indication field indication 0 indicates a low priority: if the priority indication field of one grant is indicated as 0, the transmission direction of the time-frequency domain resource indicated by the grant may be rewritten by the time-frequency domain resource indicated by the grant whose priority indication field is indicated as 1. If one DL grant and one UL grant are indicated as different priorities, the terminal performs UL transmission or DL reception according to the grant containing the higher priority indication.

The case (2), the first authorization and the second authorization are all semi-static configuration

For semi-static configuration, the network side device may configure the priority of grants in the parameter configuration, so that when a configured UL transmission collides with a configured DL transmission, for example, for a flexible symbol or slot, the terminal may determine that the collision resource is UL or DL transmission direction according to the configured priority, and perform UL transmission or DL reception. Fig. 4 is a second schematic diagram of time-frequency domain resource allocation provided in the embodiment of the present application, as shown in fig. 4, in slot n, a configured SPS transmission occalasion is partially overlapped with a configured grant transmission occalasion, and since the priority of SPS configuration is 1 and the priority of CG configuration is 0, the terminal determines that SPS is a high priority grant according to the priority size relationship between SPS configuration and CG configuration, and determines the overlapped resource as DL resource.

Case (3), type of first authorization and type of second authorization being different

For example, the type of first authorization is a dynamic indication and the type of second authorization is a semi-static configuration; alternatively, the first authorization type is semi-static configuration and the second authorization type is dynamic indication. In this case, the terminal determines DL reception or UL transmission behavior according to high priority transmission according to the dynamically indicated grant and/or the priority of semi-statically configured grant.

Alternatively, the network may configure whether the priority in the dynamic indication (DCI) may override the semi-statically configured priority.

Specifically, a network configuration dynamic indication (DCI) may override a priority indication of a semi-static configuration, such that the dynamically indicated scheduled resource is a DL resource; or alternatively, the process may be performed,

the network configuration DCI may not override the semi-statically configured priority, i.e. the UE does not expect to receive the resource transmission direction indicating the DCI of the same priority as the transmission direction of the semi-statically configured transmission.

Mode 3, for the case where the feature information includes authorization type information

And the terminal determines that the authorization with the dynamic indication of the authorization type in the first authorization and the second authorization is high priority or determines that the authorization with the semi-static configuration of the authorization type in the first authorization and the second authorization is low priority based on the authorization type information of the first authorization and the authorization type information of the second authorization.

In case the grant types of the first grant and the second grant are different, for example, one grant is a dynamic indication and the other grant is a semi-static configuration, when the resources indicated by the first grant and the second grant collide, the terminal may determine UL transmission or DL reception behavior in a manner that the dynamically indicated grant is prioritized.

Mode 4, for the case where the feature information includes authorized bearer resource type information

And the terminal determines that the authorization of which the bearer resource type is the target bearer resource type in the first authorization and the second authorization is high priority or determines that the authorization of which the bearer resource type is the non-target bearer resource type in the first authorization and the second authorization is low priority based on the bearer resource type information of the first authorization and the bearer resource type information of the second authorization.

Specifically, the target bearer resource type may include at least one of: the coreset number where the authorization is located; search space set number.

In the embodiment of the application, the network side device may configure the terminal to determine different priorities of different authorizations according to the type of the authorized bearer resources.

Optionally, taking the type of grant as DCI signaling as an example, the network side device may configure the terminal to determine different priorities of different DCIs according to the coreset number where the DCI is located, for example, the index size of the coreset. For example, the target bearer resource type is coreset #0, and DCI detected by the terminal at coreset #0 has a higher priority than DCI detected at other coresets.

Optionally, the network side device may also configure the terminal to determine different priorities of different DCIs according to a search space set number where the DCIs located, for example, a (index) size of the search space set.

Specifically, for example, the target bearer resource type is sss#0, and DCI detected by the terminal in sss#0 has a higher priority than DCI detected in other SSS. Alternatively, the priority of the grant in CSS set is higher than the priority of the grant in USS set. Alternatively, the priority of a particular CSS is higher than the priority of a USS, e.g., type-0-PDCCH CSS set or Type1-PDCCH CSS set is higher than the priority of a USS set.

Mode 5 for the case where the feature information includes authorized format information

And the terminal determines that the authorization with the format information in the first authorization and the second authorization as the target format is high in priority or determines that the authorization with the type of the bearing resource in the first authorization and the second authorization as the non-target format is low in priority based on the format information in the first authorization and the format information in the second authorization.

Specifically, the target format includes: DCI format information. The target format is, for example, DCI format 0-2 or DCI format 1-2. In practice, the network side device may configure: the priority of DCI format 0-2/1-2 is higher than that of DCI format 0-1/1-1, and the priority of DCI format 0-2/1-2 is higher than that of DCI format 0-0/1-0.

Mode 6 for the case where the feature information includes type information of authorized scrambling

The terminal determines that the authorization with the type information of the first authorization and the second authorization scrambling as the target scrambling type is high priority or determines that the authorization with the type information of the first authorization and the second authorization scrambling as the non-target scrambling type is low priority based on the type information of the first authorization scrambling and the type information of the second authorization scrambling.

Specifically, the target scrambling type information includes: DCI scrambled RNTI. The target scrambling type is, for example, MCS-RNTI scrambling. In practice, the network side device may configure: the priority of the DCI scrambled by the MCS-RNTI is higher than that of the DCI scrambled by the C-RNTI and the SP-RNTI.

Mode 7, including grant scheduled channels and/or types of signals for characteristic information

The terminal determines that the grant with the type of the channel and/or signal scheduled in the first grant and the second grant as the target type is high priority or determines that the grant with the type of the channel and/or signal scheduled in the first grant and the second grant as the non-target type is low priority based on the type of the channel and/or signal scheduled in the first grant and the type of the channel and/or signal scheduled in the second grant.

Specifically, the network side device may configure the terminal to determine the priority levels of different grants according to the types of channels and/or signals scheduled by the grants. The target type is, for example, a control channel.

In practice, the network side device may configure: the priority of the control channel is higher than the priority of the data channel and also higher than the priority of the reference signal; or the priority of the control channel is greater than the priority of the data channel, and the priority of the data channel is greater than the priority of the reference signal; alternatively, the priority of the control channel is greater than the priority of the reference signal, and the priority of the reference signal is greater than the priority of the data channel. For example, a control channel such as PUCCH, a data channel such as PDSCH, and a reference signal such as SRS.

For example, in the case where the priority of the control channel configured by the network side device is greater than the priority of the data channel and the priority of the data channel is greater than the priority of the reference signal, the priority of the grant of the scheduling control channel is higher than the priority of the grant of the scheduling data channel, and the priority of the grant of the scheduling data channel is higher than the priority of the grant of the scheduling reference signal.

Mode 8, for the case where the characteristic information includes information on the number of retransmissions of the channel and/or signal for which scheduling is authorized

And the terminal determines that the grant of which the retransmission number information of the channel and/or signal scheduled in the first grant and the second grant meets the target condition is high priority or determines that the grant of which the retransmission number information of the channel and/or signal scheduled in the first grant and the second grant does not meet the target condition is low priority based on the retransmission number information of the channel and/or signal scheduled in the first grant and the retransmission number information of the channel and/or signal scheduled in the second grant.

Specifically, the network side device may configure the terminal to determine the priority level of different DCIs according to the channel and/or the retransmission number of the signal scheduled by the DCIs. The target conditions include: the number of retransmissions of the granted scheduled channel and/or signal is greater than a threshold.

For example, the network side device may configure: if a DCI schedules repeated transmission, the priority of the DCI is low priority grant; or the priority of the DCI is a high priority grant.

Alternatively, the network side device may configure: if the retransmission times scheduled by DCI 1 are higher than those scheduled by DCI 2, the terminal considers the priority of DCI 1 as low-priority authorization; alternatively, the terminal recognizes the priority of DCI 1 as a high priority grant.

In the embodiment of the present application, the time difference between the end symbol of the high priority grant and the time reference point is greater than or equal to the effective time of the first resource indicated by the high priority grant; wherein the time reference point comprises at least one of:

a) The earliest starting symbol in the first resource and the second resource;

in particular, the terminal expects that the earliest start symbol of the first resource and the second resource is not earlier than the effective time (denoted as t_proca time or processing time) after the end symbol of the high priority grant, which changes the transmission direction of the second resource indicated by the low priority grant. Wherein the first resource partially or fully overlaps the second resource.

Fig. 5 is a third schematic diagram of time-frequency domain resource allocation provided in the embodiment of the present application, where, as shown in fig. 5, the network side device configures the terminal to determine the grant with the subsequent receiving time as the high priority grant.

The terminal expects a start symbol of a resource, which overlaps the earliest resource indicated by a late grant (DL grant) that changes the transmission direction of the resource indicated by the UL grant, to be not earlier than t_proca time after the last symbol received by the PDCCH.

The effective time can be the same as the cancel time of the UL channel being cancelled at different priorities, namely

T_procA＝T _proc,2 The method comprises the steps of carrying out a first treatment on the surface of the Wherein T is _proc,2 Preparing time for PUSCH;

T _proc,2 =max((N ₂ +d _2,1 )(2048+144)·κ2 ^-μ ·T _C ,d _2,2 )，N ₂ is a parameter related to subcarrier spacing and related to terminal processing capability, let d be _2,1 ＝d ₁ 。d _2,2 And d ₁ See protocol.

Alternatively, t_proca may be greater or less than the cancel time described above. T_proca=t _proc,2 +delta 1.delta1 may be defined in the protocol, and may be a UE capability related value, and may be a positive number or a negative number.

b) A start symbol of an overlapping resource of the first resource and the second resource;

fig. 6 is a schematic diagram of time-frequency domain resource allocation provided in the embodiment of the present application, and as shown in fig. 6, a network side device configures a terminal to determine a grant with a subsequent receiving time as a high priority grant.

The terminal expects that the start symbol of the overlapping resource indicated by at least two scheduled grants (DL grant) that changes the transmission direction of the resource indicated by the UL grant is not earlier than the last symbol received by the PDCCH by t_procb time.

T_procB＝T _proc,2 The method comprises the steps of carrying out a first treatment on the surface of the Or alternatively, the first and second heat exchangers may be,

T_procB＝T _proc,2 +delta 2.delta2 may be defined in the protocol, and may be a terminal capability related value, and may be a positive number or a negative number.

c) And the first resource and the second resource overlap the initial symbol of the slot where the resource is located.

In particular, the validation time may be configured by the network side device or specified in the protocol.

The following describes a manner in which, in the embodiments of the present application, a terminal determines, based on the priority of the first grant and/or the second grant, a transmission direction of the first resource and the second resource, and further determines that a low-priority grant indicates an available resource of a resource.

Specifically, the terminal determines the transmission directions of the first resource and the second resource based on granularity and the priority of the first grant and/or the second grant, and further determines available resources of low-priority grant indication resources; wherein the granularity is used for indicating the rewriting range of the scheduling resource. The granularity may include at least one of: time cell granularity; frequency domain subband granularity; overlapping frequency domain granularity; scheduling granularity. The time unit may include a subband, a slot, or a subframe. It should be noted that the subband may be an existing subband or subband set, or a subband in which the newly defined frequency domain contains k PRBs, and the time domain granularity may be configured by the network.

Fig. 7 is a fifth schematic diagram of time-frequency domain resource allocation provided in the embodiment of the present application, as shown in fig. 7, at time t1, the terminal receives an UL grant scheduling slot n UL resource; at time t2 (t 1< t 2), the terminal receives a DL resource of DL grant scheduling slot n; DL resources of DL grant schedule partially overlap UL resources of UL grant schedule. Assume that the terminal determines that the UL grant is a low priority grant and the DL grant is a high priority grant based on the network configuration.

Network side equipment configuration: the transmission direction of the resources indicated by the low priority grant may be overwritten by the transmission direction of the resources indicated by the high priority grant.

Optionally, the implementation manner of determining, by the terminal, the transmission direction of the second resource of the low priority grant indication based on granularity and the transmission direction of the first resource of the high priority grant indication may include at least one of:

in implementation mode 1, when the granularity includes the granularity of the time unit, the terminal determines, based on the granularity of the time unit and the transmission direction of the resources indicated by the high priority grant, the transmission directions of all frequency domain resources on the time unit where the first resource and the second resource are located, and further determines available resources of the resources indicated by the low priority grant.

Referring to fig. 7, in the case that the granularity includes a time unit granularity and the time unit includes a slot, the terminal considers slot n as DL slot, and changes the transmission directions of all the time-frequency domain resources on the slot where the PDCCH indication resource is located into a downlink direction.

In implementation 2, when the granularity includes the frequency domain subband granularity, the terminal determines a transmission direction of a frequency domain subband on a time unit where the first resource and the second resource are located based on the frequency domain subband granularity and a resource transmission direction indicated by high priority grant, so as to determine available resources of low priority grant indication resources.

Referring to fig. 7, in the case where the granularity includes the granularity of the frequency domain sub-band, the terminal changes the transmission direction of the resources of the sub-band where the scheduling resource is located in the time domain to the downlink direction. The subband size is configured for a network, e.g. one subband m contains k PRBs.

Implementation 3, where the granularity includes the overlapping frequency domain granularity, the terminal determines a transmission direction of the overlapping frequency domain resource on a time unit where the first resource and the second resource are located based on the overlapping frequency domain granularity and a resource transmission direction indicated by high priority grant; wherein the overlapping frequency domain resource is a frequency domain resource where the second resource overlaps the first resource.

Referring to fig. 7, in the case where the granularity includes the overlapping frequency domain granularity, the terminal changes the transmission direction of the overlapping frequency domain resource to the downlink direction with the whole slot n in the time domain. For a full duplex terminal, according to the authorization of the post-scheduling, the terminal considers that the whole slot n is: frequency domain resource B is DL resource, frequency domain resource a is UL resource, and frequency domain resource C is DL resource.

It is noted that for half duplex terminals, the terminal will only transmit one direction, UL or DL, at a time, and the terminal should ignore the UL resource a transmission and only receive DL resources B and C.

Implementation 4, where the granularity includes the scheduling granularity, the terminal determines a transmission direction of a time-frequency domain resource where the first resource and the second resource overlap based on the scheduling granularity and a transmission direction of a first resource indicated by high priority grant.

Referring to fig. 7, in case that the granularity includes a scheduling granularity, the terminal determines a transmission direction of the high priority grant indication resource as a downlink direction. For a full duplex terminal, the terminal considers that: frequency domain resources a and B on time domain resources D and F are UL, frequency domain resource a on time domain resource E is UL, and frequency domain resources B and C on time domain resource E are DL.

It is noted that for half duplex UEs, the UE will only transmit one direction, UL or DL, at a time, and the UE should ignore the frequency domain resource a on the time domain resource E and transmit only the frequency domain resources B and C.

Notably, for frequency domain resources a and B on time domain resource F, for PUSCH, transmission may not be possible due to lack of a corresponding DMRS or due to phase continuity.

Notably, UL-DL transition times may be required for different transmission directions. The network may indicate or predefine the Ngap of the UL-DL transition. I.e. before the start symbol or after the end symbol of the high priority grant indicating resource, the terminal does not allow transmission of the low priority grant indicating resource, e.g. uplink transmission and DL reception.

In the embodiment of the present application, when detecting that a first resource of a first grant indication sent by a network side device overlaps with a second resource of a second grant indication partially or completely, a terminal determines a transmission direction of a low priority grant indication resource based on a transmission direction of a high priority grant indication resource, and then the terminal transmits a channel or signal of the high priority grant scheduling on the high priority grant indication resource; and the terminal cancels part or all of the low priority grant scheduled channels or signal transmissions.

In particular, the terminal cancels all low priority grant scheduled channels or signals transmissions, i.e. if the two grants conflict with scheduled resources, the low priority grant scheduled channels or signals are no longer transmitted.

And implementations of the terminal canceling part of the low priority grant scheduled channel or signal transmission may include at least one of:

1) The terminal cancels the transmission of the low priority grant scheduled channel or signal on the resource indicated by the low priority grant from the beginning symbol of the overlapped resource; wherein the overlapping resource is a time-frequency domain resource where the second resource overlaps the first resource.

If two grants conflict with scheduled resources, no low priority grant scheduled channel or signal is transmitted from the beginning symbol of the overlapping resources. Referring to fig. 7, the terminal transmits (transmits or receives) only the frequency domain resources a, B on the time domain resource D.

2) The terminal cancels transmission of the low priority grant scheduled channel or signal on the resource overlapping resource on the resource indicated by the low priority grant.

If two grants conflict with scheduled resources, no channel or signal scheduled by the low priority grant is transmitted on the overlapping resources, and the portion of the low priority grant indicated resource that does not conflict with the high priority grant indicated resource can be transmitted. Referring to fig. 7, the terminal transmits the frequency domain resources a, B on the time domain resources D, F and the frequency domain resource a on the time domain resource E.

In the embodiment of the application, the network side can also be configured: the terminal determines the transmission direction of a time-frequency resource first, and then carries out UCI multiplexing. Or alternatively, the process may be performed,

the terminal performs UCI multiplexing first, and then determines the transmission direction of the time-frequency resource.

If the transmission direction of the resource after UCI multiplexing is opposite to that of the resource indicated by the terminal, the terminal discards the UCI.

In this embodiment of the present application, for determining the sequence of different DCIs, a reference subcarrier spacing may be used. The reference subcarrier spacing may be configured by the network.

Alternatively, the network may configure, if the UE is scheduled or configured for repeated transmission of a channel or signal, the priority of the channel or signal:

for example, for URLLC traffic, retransmission is an important means of ensuring high reliability, and thus, the network can configure the retransmission to be high priority. When a scheduled channel or signal overlaps with a time or frequency domain of a scheduled or configured high priority repeated transmission, the non-repeated channel or signal is discarded.

As another example, for implementing coverage enhancement aspect functionality, the network may configure the repeatedly transmitted channels or signals to be low priority. When a scheduled channel or signal overlaps with a time or frequency domain of a scheduled or configured high priority repeated transmission, the non-repeated channel or signal is discarded.

Alternatively, the network may be configured, with priority determination based on channel or signal repetition. If a channel or repeated transmission of a signal encounters an unavailable resource, its repeated transmission will be delayed (postpon), the channel may be considered low priority (or vice versa). If a duplicate transmission of a channel or signal encounters an unavailable resource, its duplicate transmission will be discarded, the channel may be considered high priority (or vice versa).

According to the method for determining the transmission direction of the resource, the execution body can be the device for determining the transmission direction of the resource. In the embodiment of the present application, a method for determining a resource transmission direction by using a resource transmission direction determining device is taken as an example, and the resource transmission direction determining device provided in the embodiment of the present application is described.
