Referring to fig. 2, fig. 2 is a flowchart of a method for determining a collision resource according to an embodiment of the present invention, where the method is applied to a terminal, and as shown in fig. 2, the method includes the following steps:

step 201, determining whether a plurality of serving cells of the terminal have a conflict time resource according to activation information of a secondary cell (Scell), where the plurality of serving cells include the secondary cell, and the conflict time resource is: different time resources are configured for uplink and downlink of different service cells;

wherein the activation information comprises at least one of:

the status and command reception time of the secondary cell;

The number of the secondary cells may be one or more. The plurality of serving cells may belong to serving cells of a plurality of network devices, or may belong to a plurality of serving cells of the same network device.

The time resources with different uplink and downlink configurations between different serving cells may be that, on the same time resource, the serving cell is configured as a downlink time resource, and other serving cells are configured as uplink time resources, or on the same time resource, the serving cell is configured as downlink receiving, and other serving cells are configured as uplink transmitting. This results in half-duplex (half duplex) terminals not being able to transmit simultaneously with the multiple serving cells on the time resource, resulting in collisions.

The determining whether the conflict time resources exist in the multiple serving cells of the terminal according to the activation information of the secondary cell may be determining a state of each secondary cell according to the activation information of the secondary cell, and determining whether the conflict time resources exist in the multiple serving cells of the terminal according to the state of each secondary cell, or determining whether the conflict time resources exist in the multiple serving cells of the terminal according to the state of each secondary cell and the primary cell. For example: whether the downlink transmission configuration of a certain auxiliary cell conflicts with the uplink and downlink transmission configuration of other cells can be judged, and whether the uplink and downlink transmission configuration of the certain auxiliary cell conflicts with the uplink/downlink/flexible resource configuration of other cells can be judged. If the time resource A of an activated auxiliary cell is a downlink time resource, and the time resource A is determined to be a collision time resource according to the fact that the time resource A of another activated auxiliary cell is an uplink time resource.

In addition, the above-mentioned determining whether the conflict time resource exists in the plurality of serving cells of the terminal may be determining that the conflict time resource exists and determining which time resource the conflict time resource is.

In this embodiment of the present invention, the time resource may include at least one of the following: symbol, slot, subframe, such as an Orthogonal Frequency Division Multiplex (OFDM) symbol. Of course, this is not limited, for example: the time resource may be a newly defined time resource in a subsequent protocol, such as a time resource smaller than a symbol.

It should be noted that the conflict time resource may be one or more time resources. The terminal may be a half-duplex (half duplex) terminal.

Optionally, the terminal may meet at least one of the following conditions:

the network is configured with a plurality of service cells of the terminal and is configured with an enabling half-duplex behavior;

the terminal does not have the capability of transmitting and receiving simultaneously on a plurality of serving cells;

the terminal reports the capability of supporting the half-duplex terminal behavior;

the terminal is not configured with monitoring of a downlink control information format (DCI format) 2-0.

In the embodiment of the invention, whether the conflict time resources exist in the plurality of service cells of the terminal can be determined, so that the transmission of the terminal can be selectively transmitted in the conflict time resources to avoid conflict and improve the transmission performance of the terminal, and whether the transmission in the plurality of service cells can be transmitted can be determined, so that the resources in each service cell can be more fully utilized. In addition, whether the conflict time resources exist in the multiple serving cells of the terminal is judged according to the activation information of the secondary cell, so that the sending and receiving comprehension between the network equipment and the terminal for the conflict time resources is consistent, the utilization rate of uplink and downlink resources is improved, and the abandon of excessive uplink and downlink transmission is avoided.

As an optional implementation manner, the configuring different time resources for uplink and downlink of different serving cells includes: at least one of a first time resource, a second time resource, a third time resource, and a fourth time resource;

wherein, on the first time resource, the configuration of the serving cell is an uplink time resource, and the configuration of the serving cell is a downlink time resource;

on the second time resource, the configuration of the serving cell is uplink transmission, and the configuration of the serving cell is downlink reception;

on the third time resource, the configuration of the serving cell is uplink transmission, and the configuration of the serving cell is downlink time resource;

and on the fourth time resource, the configuration of the serving cell is the uplink time resource, and the configuration of the serving cell is the downlink reception.

The first time resource may be understood as uplink time resources configured in some serving cells, and downlink time resources configured in other serving cells; the second time resource may be understood as some serving cells configured to transmit uplink, and some serving cells configured to receive downlink; the third time resource may be understood as uplink transmission configured in some serving cells, and downlink resource configured in other serving cells; the fourth time resource may be understood as some serving cells configured as uplink resources, and some serving cells configured as downlink reception.

According to the embodiment, the resource of uplink and downlink time resource conflict can be determined, and the resource of uplink and downlink transmission conflict can also be determined. That is, the above-mentioned collision is that different serving cells configure uplink and downlink symbols on the same time resource, or uplink and downlink transmission are opposite, or uplink and downlink transmission are not matched with uplink and downlink symbols.

As an optional implementation manner, the determining, according to the activation information of the secondary cell, whether a conflict time resource exists in a plurality of serving cells of the terminal includes:

judging whether conflict time resources exist in a plurality of service cells of the terminal according to configuration information of an activated cell in the plurality of service cells;

wherein the active cell comprises:

an activated secondary cell; or

A primary cell and an activated secondary cell.

Wherein the activated secondary cell is determined according to the activation information of the secondary cell.

In this embodiment, it is determined whether there is a time resource conflict in multiple serving cells of the terminal only according to the configuration information of the active cell, and it is determined whether there is a time resource conflict in uplink and downlink between the multiple serving cells without using the configuration information of the deactivated secondary cell. The network equipment and the terminal can be prevented from understanding the conflict time resources consistently, so that the resource utilization rate and the transmission performance are improved.

Optionally, the configuration information includes at least one of:

upstream transmission configuration information of an activated upstream Bandwidth Part (BWP);

downlink reception configuration information of the activated downlink BWP;

uplink transmission configuration information of a serving cell;

receiving configuration information by the downlink of the serving cell;

configuration information of uplink resources;

configuration information of downlink resources;

configuration information for flexible resources.

It should be noted that the content of the configuration information of different active cells may be the same or different, where the content here refers to at least one of the above items. For example: some of the configuration information for the active cells includes configuration information for flexible resources, and other of the configuration information for the active cells does not include configuration information for flexible resources. In addition, the uplink transmission configuration information of the serving cell and the downlink reception configuration information of the serving cell may be understood as the uplink transmission configuration information and the downlink reception configuration information of the active cell, because the active cell is the serving cell. The configuration information may be RRC configuration information, or may be other configuration information, which is not limited to this.

In addition, the activated uplink BWP may be a dormant uplink BWP (dormant BWP) or a non-dormant uplink BWP, and the activated downlink BWP may be a dormant downlink BWP (dormant BWP) or a non-dormant downlink BWP.

Further, the configuration information for the dormant downlink BWP may be at least one of the following configuration information:

CSI-RS and a Synchronization Signal Block (SSB).

Wherein the CSI-RS may include at least one of:

CSI-RS for BFD, CSI-RS for CSI measurement.

The uplink resource, the downlink resource and the flexible resource may be an uplink symbol, a downlink symbol and a flexible symbol, or may be an uplink time slot, a downlink time slot and a flexible time slot, or may be an uplink subframe, a downlink subframe and a flexible subframe.

In addition, the uplink transmission configuration information may include configuration information of at least one of the following:

a Physical Random Access Channel (PRACH), a Sounding Reference Signal (SRS), a Physical Uplink Shared Channel (PUSCH), and a Physical Uplink Control Channel (PUCCH);

the downlink reception configuration information may include configuration information of at least one of:

a Physical Downlink Shared Channel (PDSCH), a Channel state information reference signal (CSI-RS), and a Physical Downlink Control Channel (PDCCH).

Optionally, in a case that the terminal receives the activation command, the activated secondary cell may include a secondary cell activated by the activation command; or

In a case where the terminal receives the deactivation command, the activated secondary cell may not include the secondary cell deactivated by the deactivation command.

For example: if a certain secondary cell is an active serving cell, the activated downlink BWP configured downlink reception, the activated uplink BWP configured uplink transmission, the Scell configured downlink reception, the Scell configured uplink transmission, and the RRC configuration of at least one of the Scell configured uplink time resource, downlink time resource, and flexible time resource may be used to determine whether there is a collision with another serving cell.

Another example is: and if the certain secondary cell is the deactivated serving cell, whether the resources of the serving cell conflict or not is not judged.

Or a certain secondary cell is a deactivated serving cell, the UE considers all symbols on the deactivated serving cell to be flexible symbols. For example: for a deactivated secondary cell of the plurality of serving cells, all time resources of the deactivated secondary cell are flexible time resources. Here, the time resource may be a symbol, a slot, or a subframe.

Because whether a plurality of serving cells conflict or not is judged on each time resource, only uplink transmission configured by a high-level signaling, or downlink receiving cells, or the time resources configured by the high-level signaling as downlink or uplink can be considered, that is, flexible time resources configured by the high-level signaling are not considered, and if a symbol of a certain serving cell is configured as a flexible symbol by the high-level signaling, the reference serving cell which is not included in the cell is determined. The determination of the reference serving cell includes determining a cell with a lowest cell index value among the plurality of serving cells, i.e., determining a cell with a lowest cell index value regardless of whether a symbol is configured as a flexible symbol by a higher layer signaling. And the UE determines the reference service cell in the cell of which the time resource is configured by the high-level signaling on the time resource, namely uplink transmission or downlink reception, or the high-level signaling is configured as the downlink or uplink time resource. Further, if a symbol of a certain serving cell is configured as a flexible symbol by higher layer signaling, the serving cell does not perform a determination on the symbol whether or not there is a collision time resource with a reference serving cell or other serving cells.

Thus, if the UE assumes time resources on the serving cell for the deactivated secondary cell, the UE is flexible in time resources, and the secondary cell is not included in the determination of the reference serving cell according to the above rule. Further, the secondary cell does not perform the determination of whether there is a conflicting time resource with the reference cell or other cells.

Optionally, in a case that the terminal receives the activation command:

the activated secondary cell comprises the secondary cell activated by the activation command at a first time; and/or

The activated secondary cell does not include the secondary cell activated by the activation command at a second time;

wherein the difference between the first time and the receiving time of the activating command is greater than or equal to T1 time, the difference between the second time and the receiving time of the activating command is less than or equal to T1 time, and the T1 time is the time delay of activating the secondary cell.

In this embodiment, the activated cell for determining the conflict time resource may be accurately determined according to the time T1, so that it may be more effectively ensured that the network device and the terminal have the same understanding on the conflict time resource. For example: the terminal receives the MAC-CE indication to activate the secondary cell, the terminal uses the activated downlink BWP configured downlink receiving, the activated uplink BWP configured uplink sending and the Scell configured downlink receiving of the Scell after T1 time, the Scell configured uplink sending and the RRC configuration of at least one of the uplink time resource, the downlink time resource and the flexible time resource configured by the Scell determine whether conflict with other serving cells, wherein, when the conflict time resource of a plurality of serving cells is judged before T1 time, the secondary cell is considered as a deactivated cell.

Optionally, the time resource of the secondary cell activated by the activation command at the second time is a flexible time resource.

For example: and the terminal considers the time resource of the deactivated secondary cell as the flexible time resource, and then the terminal considers the time resource of the secondary cell as the flexible time resource before T1 time.

Thus if the UE assumes time resources on the serving cell for the deactivated secondary cell, the secondary cell will not be included in the determination of the reference serving cell until T1 time according to the above rule for flexible time resources. Further, the secondary cell does not perform the determination of whether there is a conflicting time resource with the reference cell or other cells.

Optionally, when the terminal receives the deactivation command:

the activated secondary cell comprises a secondary cell deactivated by the deactivation command at a third time; and/or

At a fourth time the activated secondary cell does not include a secondary cell deactivated by the deactivation command;

wherein a difference between the third time and the reception time of the deactivation command is less than or equal to a T2 time, a difference between the fourth time and the reception time of the activation command is greater than or equal to the T2 time, and the T2 time is a time delay for deactivating a secondary cell.

In this embodiment, the deactivated cell that is not used for determining the conflict time resource may be accurately determined according to the time T2, so that it may be more effectively ensured that the network device and the terminal have the same understanding on the conflict time resource. For example: the terminal receives the MAC-CE indication to deactivate the secondary cell, stops using the activated downlink BWP configured downlink reception, the activated uplink BWP configured uplink transmission and the Scell configured downlink reception of the activated secondary cell after T2 time, determines whether conflict exists with other serving cells according to the RRC configuration of at least one of the uplink time resource, the downlink time resource and the flexible time resource configured by the Scell, wherein the secondary cell is considered as the activated cell when a plurality of serving cell conflict time resources are judged before T2 time.

Optionally, the time resource of the secondary cell deactivated by the deactivation command at the fourth time is a flexible time resource.

For example: and the terminal considers the time resource of the deactivated secondary cell as the flexible time resource, and then the terminal considers the time resource of the secondary cell as the flexible time resource after T2 time.

Thus if the UE assumes time resources on the serving cell for the deactivated secondary cell, the configuration on the secondary cell will not be included in the determination of the reference serving cell after T2 time according to the above rule for flexible time resources. Further, the secondary cell does not perform the determination of whether there is a conflicting time resource with the reference serving cell or other cells.

As an optional implementation manner, the configuration information of the deactivated secondary cells in the multiple serving cells is not used to determine whether there is a conflicting time resource in the multiple serving cells.

As an optional implementation, the method further comprises:

determining a reference cell (reference cell) among the plurality of serving cells according to the activation information of the secondary cell.

In this embodiment, since the reference serving cell in the plurality of serving cells is determined according to the activation information of the secondary cell, it can be ensured that the network device and the terminal understand the reference serving cell consistently.

Optionally, the reference serving cell is: activating a cell with a lowest cell index value in cells in the plurality of serving cells;

wherein the active cell comprises:

an activated secondary cell; or

A primary cell and an activated secondary cell.

It should be noted that the activated secondary cell may refer to the above determination of the activated cell for determining the conflict time resource, which is not described herein again.

Optionally, the multiple serving cells are within one frequency band, or within one frequency band combination.

In this embodiment, the determination of the collision time resource between the serving cells within the same frequency band and the determination of the reference serving cell may be implemented, and the determination of the collision time resource between the serving cells within the same frequency band combination and the determination of the reference serving cell may be implemented.

As an optional implementation manner, the terminal may perform the following actions for the conflict time resource:

if at least one of the time resources is downlink time resource indicated by a high-level signaling on the reference serving cell, or the high-level signaling indicates that the downlink time resource is used for receiving PDCCH (physical Downlink control channel), PDSCH (physical Downlink shared channel) or CSI-RS (channel state information-reference signal) on the reference serving cell, not transmitting PUCCH (physical uplink control channel), PUSCH (physical uplink shared channel) or PRACH (physical random access channel) on the time resources on other serving cells;

and if the time resources in the time resources of the other serving cells are the downlink time resources indicated by the higher layer signaling in the reference serving cell or the higher layer signaling indicates that the time resources are used for receiving the PDCCH, the PDSCH or the CSI-RS on the reference serving cell, not sending the SRS on the time resources of the other serving cells.

If at least one time resource in the time resources of other service cells is an uplink time resource indicated by a high-level signaling on the reference service cell, or the time resource indicated by the high-level signaling is used for transmitting an uplink SRS, PUCCH, PUSCH or PRACH on the reference service cell, the PDCCH, PDSCH or CSI-RS indicated by the high-level signaling is not received on the time resources of other service cells;

indicating the high-level signaling to be downlink on other service cells and indicating the time resource for transmitting the SRS, the PUCCH, the PUSCH or the PRACH on the reference service cell as a flexible time resource by the high-level signaling;

and indicating that the high-level signaling is uplink on other service cells and indicating that the time resource for receiving the PDCCH, the PDSCH or the CSI on the reference service cell is flexible time resource by the high-level signaling.

As an optional implementation, all time resources of a Dormant secondary cell (Dormant Scell) in the plurality of serving cells are flexible time resources, where the Dormant secondary cell is in an active state, and the active BWP is a secondary cell of a Dormant BWP (Dormant BWP).

Here, the time resource may be a symbol, a slot, or a subframe.

Because whether a plurality of serving cells conflict or not is judged on each time resource, only uplink transmission configured by a high-level signaling, or downlink receiving cells, or the time resources configured by the high-level signaling as downlink or uplink can be considered, that is, flexible time resources configured by the high-level signaling are not considered, and if a symbol of a certain serving cell is configured as a flexible symbol by the high-level signaling, the reference serving cell which is not included in the cell is determined. The determination of the reference serving cell includes determining a cell with a lowest cell index value among the plurality of serving cells, i.e., determining a cell with a lowest cell index value regardless of whether a symbol is configured as a flexible symbol by a higher layer signaling. And the UE determines the reference service cell in the cell of which the time resource is configured by the high-level signaling on the time resource, namely uplink transmission or downlink reception, or the high-level signaling is configured as the downlink or uplink time resource. Further, if a symbol of a certain serving cell is configured as a flexible symbol by a high-level signaling, and no high-level signaling configures uplink transmission or downlink reception on the symbol, the serving cell does not determine whether a collision time resource exists between the symbol and a reference serving cell or other serving cells.

Thus, if for (Dormant Scell), the UE assumes time resources on the serving cell, which is flexible time resources.

Optionally, the all time resources include:

and the network side configures downlink time resources and uplink time resources.

The downlink time resource and the uplink time resource configured by the network side may be downlink time resource and uplink time resource configured by a higher layer signaling, for example: even if the high-level signaling configures the symbol of the dormant serving cell as a downlink time resource or an uplink time resource, the UE ignores the configurations, and assumes that the time resources are flexible time resources.

According to the above rules, the secondary cell is not included in the determination of the reference serving cell. Further, the secondary cell does not perform the determination of whether there is a conflicting time resource with the reference cell or other cells.

As an optional implementation, when determining a reference serving cell in the plurality of serving cells, not using configuration information of a Dormant secondary cell (Dormant Scell) in the plurality of serving cells;

or, determining a reference serving cell in the plurality of serving cells according to configuration information of an active cell in the plurality of serving cells, where the active cell includes: an activated secondary cell, or a primary cell and an activated secondary cell, the activated secondary cell being a non-dormant secondary cell;

wherein the Dormant secondary cell (Dormant Scell) is in an active state, and the active BWP is a secondary cell of Dormant BWP (Dormant BWP).

The configuration information of the active cell may be all or part of the configuration information of the active cell.

In this embodiment, it is possible to implement that the determination is made without depending on the configuration information of the dormant secondary cell when the reference serving cell is determined.

As an optional implementation manner, the configuration information of the Dormant secondary cell (Dormant Scell) in the multiple serving cells is not used to determine whether a conflict time resource exists in the multiple serving cells of the terminal; or judging whether conflict time resources exist in a plurality of service cells of the terminal according to configuration information of an active cell in the plurality of service cells, wherein the active cell comprises: an activated secondary cell, or a primary cell and an activated secondary cell, the activated secondary cell being a non-dormant secondary cell;

In this embodiment, it may be determined whether a conflict time resource exists in the plurality of serving cells of the terminal, without determining according to the configuration information of the dormant secondary cell.

Optionally, the configuration information of the dormant secondary cell includes at least one of the following:

configuration information of uplink resources;

configuration information of downlink resources;

configuring PDCCH monitoring;

a transmission configuration of a semi-persistent scheduling (SPS) PDSCH;

configuring a transmission configuration of a grant (Configured grant) PUSCH;

transmission configuration of PRACH;

a transmission configuration of CSI-RS;

a transmission configuration of the SRS;

transmission configuration of PUCCH.

Optionally, the CSI-RS is not used for at least one of:

radio Resource Management (RRM) measurements, Beam Failure Detection (BFD), and Channel State Information (CSI) measurements.

It should be noted that, this embodiment is used as an implementation manner of a network device side corresponding to the embodiment shown in fig. 2, and a specific implementation manner of this embodiment may refer to a relevant description of the embodiment shown in fig. 2, so as to avoid repeated description, and this embodiment is not described again. In this embodiment, it may also be determined whether a conflict time resource exists in a plurality of serving cells of the terminal.

The following illustrates a collision resource determination method provided by the embodiment of the present invention by using multiple embodiments:

example 1:

if the network configures a plurality of Serving cells, and if the deactivated Serving cells exist, the terminal only uses the uplink and downlink transmission configuration of the activated Scell or the uplink and downlink resource configuration to determine whether the uplink and downlink among the plurality of Serving cells conflict (i.e. the conflict time resource). Determining whether uplink and downlink among a plurality of serving cells conflict (namely, the conflict time resource) without using deactivated uplink and downlink transmission configuration or deactivated uplink and downlink resource configuration of the Scell.

Example 2:

in this embodiment, in one frequency band (frequency band), all serving cells are scells, which is as follows:

if all cells are activated scells, the cell with the lowest serving cell secondary cell index (serving cell Scell index) is reference cell.

If the non-activated Scell is included, the cell with the lowest index in the activated Scell is reference cell.

For example, within one frequency band, if 3 scells are contained, the index values are n1, n2, n3, where n1 < n2 < n3, respectively, and if all three scells are activated scells, the cell with the index value n1 is reference cell; if Scell n1 is a deactivated cell, then n2 is reference Scell.

Example 3:

after the terminal receives an activation or deactivation command of the Scell, determining a conflict time resource according to the activation delay of the Scell, which comprises the following steps:

if the terminal receives the MAC-CE indication Scell activation, the terminal uses activated downlink BWP configured downlink reception, activated uplink BWP configured uplink transmission, the Scell configured downlink reception and the Scell configured uplink transmission after T1 time, and RRC configuration of at least one of uplink time resource, downlink time resource and flexible time resource configured by the Scell determines whether conflict with other serving cells; before T1, the Scell is considered as a deactivated cell, and whether a plurality of serving cells conflict with each other is determined without using uplink and downlink transmission configuration or uplink and downlink resource configuration on the Scell.

Wherein, after the secondary cell activation command (SCell activation command) is received in slot n, the above T1 may be equal to HARQ feedback time T_HARQScell activation delay T_activationCSI reporting time T_{CSI_Reporting}In connection with, e.g., the terminal being no later than slot

It is desirable to be able to report valid CSI and perform Scell activation behavior. Namely, the above-mentioned T1 is

The NR slot length is the number of slots contained within 1 ms.

Wherein, T_HARQFor the time between downlink data transmission (DL data transmission) and HARQ feedback, in ms, T_{CSI_Reporting}The method comprises the steps of obtaining a time delay corresponding to the uncertainty of the first CSI-RS resource, obtaining a processing time delay of CSI reporting and obtaining a time delay corresponding to the uncertainty of the first CSI reporting resource. The T is_activationActivating the time delay of the Scell, and according to different scenes and configurations, T_activationThe times are different, for example: may be related to at least one of the following factors:

whether the Scell is a known Scell or not;

configuring a radio resource management Measurement time Configuration (SS block based RRM Measurement Configuration, SMTC) period;

whether the UE configures the periodical or version continuous CSI reporting;

the frequency band of the Scell;

whether the band to which the mobile terminal belongs has an activated cell.

For example: if the activated Scell is known to be and belongs to the frequency range FR1, T if the number of cycles of secondary cell simulation (measurement cycle) is less than or equal to 160ms_activationMay be equal to T_FirstSSB+5ms；

In case that the secondary cell measurement cycle is greater than 160ms, T_activationMay be equal to T_{SMTC_MAX}+T_rs+5ms。

In addition, if the activated Scell is an unknown Scell and belongs to the frequency range FR1, T is detected once by Scell_activationMay be equal to 2 × T_{SMTC_MAX}+2×T_rs+5ms。

In addition, if the activated secondary cell belongs to the frequency range FR2 and there is at least one activated serving cell on the frequency band of FR2, and the following condition is satisfied, T_activationMay be equal to T_FirstSSB+5ms：

Wherein, T is detected once by Scell_activationMay be equal to 2 × T_{sMTC_MAX}+2×T_rs+5ms。

If the activated Scell belongs to FR2 and there is at least one activated serving cell on the band of FR2, and the following condition is satisfied, the taction _ time is TFirstSSB +5 ms:

SMTC provided with Scell

The activated SSBs on other scells and the SSB of the Scell can ensure spatial quasi co-location.

Wherein, the above-mentioned T_{SMTC_MAX}Comprises the following steps: maximum values of SMTC periods corresponding to the plurality of secondary cells;

t above_FirstSSB is as follows: at n + T_HARQAfter +3ms, time to next SSB;

t above_rsComprises the following steps: if a secondary cell is addedWhen the SMTC configuration of the secondary cell is received in the signaling, T is_rsIs the SMTC period. Otherwise, the frequencies are the same for SSB, the sub-carrier intervals are the same, and the SMTC period is configured through higher layer signaling measObjectNR.

Example 4:

if the terminal receives the MAC-CE indication to deactivate the Scell, the terminal stops using the activated downlink BWP configuration downlink reception, the activated uplink BWP configuration uplink transmission, the Scell configuration downlink reception and the Scell configuration uplink transmission after T2 time, and the RRC configuration of at least one of the uplink time resource, the downlink time resource and the flexible time resource configured by the Scell determines whether conflict with other serving cells; when a plurality of serving cell conflict time resources are judged before T2 time, the Scell is considered as an activated cell, wherein:

the T2 may be n + T _ HARQ + X ms, where X is a number greater than or equal to 0.

THARQ is the time between downlink DL data transmission and HARQ feedback.

Example 5:

in addition to the Scell being in an activated and deactivated state, the activated BWP of the activated Scell may be a dormant BWP, i.e., a dormant BWP. For the case that the active BWP is a dormant BWP, the terminal may only need to perform at least one of the following operations on the BWP: beam failure detection (beam failure detection), CSI measurement, and other RRC configurations are not in effect. For example, RACH configuration, SRS configuration, PUCCH configuration, configuration granted (configured grant) PUSCH configuration, PDCCH search space set (search space set) configuration, Semi-Persistent Scheduling (SPS) PDSCH configuration, etc.

When determining whether the uplink and downlink configurations of a plurality of serving cells conflict, for a scell whose active BWP is a dormant BWP, the UE may still use the configuration information (for example, RRC configuration) of the downlink BWP, and may only use the following downlink configuration to determine whether the corresponding resource conflicts with other serving cells:

CSI-RS and/or SSB.

Wherein the CSI-RS may include at least one of:

CSI-RS for BFD, CSI-RS for CSI measurement.

Or, the terminal determines whether the uplink and downlink configuration conflict with other serving cells exists by using uplink and downlink transmission of other downlink BWPs or configurations of uplink BWPs except for dormant BWPs. The BWP may be at least one of:

a first non-dormant BWP (first non-dormant BWP);

a first Active Downlink bwp (first Active Downlink bwp);

the network side signals the indicated BWP through RRC.

The BWP may be a downlink BWP, and the corresponding uplink BWP is an uplink BWP with the same ID as the downlink BWP.

And when the terminal receives the DCI to indicate that the active BWP of the Scell is the BWP of the dormant, the UE uses the BWP as the active DL BWP.

The firstActiveDownlinkBWP is configured for the network, and when the Scell is activated, the UE uses the BWP as an activated BWP. The terminal uses the downlink configuration in the first-non-dormant-BWP or the first ActivateDownlink BWP as the downlink configuration of the scell with the activated downlink BWP as dormant BWP, the configuration of the uplink BWP with the same BWP ID as the uplink configuration of the scell with the activated uplink BWP as dormant BWP, and the configuration of the serving cell is used as the configuration judgment of the serving cell and the uplink and downlink conflicts of other serving cells according to the downlink or uplink configuration.

Or, the network may indicate a BWP-ID through the RRC, and the UE uses the configuration of the uplink BWP or the downlink BWP corresponding to the ID as the configuration judgment of the serving cell and the uplink and downlink conflicts of other serving cells.

Example 6:

the network may configure multiple serving cells to the terminal, where the activation BWP of at least one scell is a dormant BWP, and the terminal does not have configuration information of the PDSCH on the dormant BWP, or obtains PDSCH configuration information, but does not use the configuration information, where the configuration information includes PDSCH time domain resource allocation and other information.

When the HARQ-Ack feedback configured for the terminal by the network uses the HARQ-Ack codebook (i.e., the semi-static codebook) of Type 1(Type-1), the terminal may determine the PDSCH occasion and determine the HARQ-Ack codebook according to the configuration of the time domain resource allocation of the PDSCH in the activated downlink BWP of the activated BWP on each serving cell.

Further, when the activated downlink BWP of one or more serving cells of the UE is dormant BWP, the configuration of the PDSCH is not used or not used, that is, the PDSCH occasion on the serving cell is not present in the HARQ-Ack codebook. Therefore, the bit length in the HARQ-Ack codebook fed back by the terminal is reduced, the transmission performance of HARQ-Ack feedback can be improved, or the resources occupied by HARQ-Ack feedback bits are reduced.

Or, when the activated downlink BWP of one or more serving cells of the terminal is dormant BWP, the UE determines the occasion of the PDSCH using the PDSCH configuration of other downlink BWPs except the dormant BWP, and determines the HARQ-Ack codebook based on the occasion. The following PDSCH configuration of downlink BWP of the serving cell may be used:

first-non-dormant-BWP

firstActiveDownlinkBWP

BWP indicated by network through RRC signaling

And when the UE receives the DCI to indicate that the active BWP of the Scell is the BWP of the dormant, the UE uses the BWP as the active DL BWP.

The firstActiveDownlinkBWP is configured for the network, and when the Scell is activated, the BWP is used as the activated BWP by the UE. And the UE uses the PDSCH configuration in the first-non-downlink-BWP or first-ActivateDownlink BWP as the PDSCH configuration of the scell with the downlink BWP as the downlink BWP, and the PDSCH configuration is used for determining the HARQ-Ack codebook.

Or, the network may indicate a BWP through RRC, and the UE uses the PDSCH configuration in the BWP as the PDSCH configuration of the scell activating downlink BWP as dormant BWP, and uses the PDSCH configuration to determine the HARQ-Ack codebook.

And the determination of the HARQ-Ack codebook is the determination of the length of the HARQ-Ack codebook, the bit sequence in the codebook and other information.

Example 7:

in addition to the Scell being in an activated and deactivated state, the activated BWP of the activated Scell may be a dormant BWP, i.e., a dormant BWP. For the case that the active BWP is a dormant BWP, the terminal may only need to perform at least one of the following operations on the BWP: beam failure detection (beam failure detection), CSI measurement, preferably, partial SRS transmission, and other RRC configurations are not in effect. For example, RACH configuration, SRS configuration, PUCCH configuration, configuration granted (configured grant) PUSCH configuration, PDCCH search space set (search space set) configuration, Semi-Persistent Scheduling (SPS) PDSCH configuration, etc. Preferably, for SRS transmission, only partial SRS transmission may be supported, for example, SRS with a period greater than a preset value or a configuration value may be transmitted.

When determining whether the uplink and downlink configurations of a plurality of serving cells conflict, for the Scell whose active BWP is dormant BWP, the UE ignores the uplink symbol or the downlink symbol configured by the RRC, and the UE assumes that all symbols of the Scell whose active BWP is dormant BWP are flexible symbols.

If the symbols of the Scell do not have the above-mentioned valid RRC configuration sent or received, the serving cell of the Scell is not used as the serving cell determined by the reference cell because the serving cell is assumed to be a flexible symbol. And determining a reference service cell in other cells which are judged to be downlink symbols or uplink symbols.

If the symbol of the Scell includes the above-mentioned effective RRC configured uplink transmission or downlink reception, if the effective RRC configuration includes downlink transmission, determining the symbol as a downlink symbol; if the validated RRC configuration contains uplink transmission, the symbol is determined to be an uplink symbol. The uplink transmission of the RRC configuration comprises configuration information of at least one of the following: a physical random access channel PRACH, a sounding reference signal SRS, a physical uplink shared channel PUSCH and a physical uplink control channel PUCCH; the downlink reception of the RRC configuration comprises configuration information of at least one of the following: the physical downlink shared channel PDSCH, the channel state information reference signal CSI-RS and the physical downlink control channel PDCCH.

On each symbol, according to whether the symbols in the multiple serving cells are uplink symbols or downlink symbols, a reference cell in the multiple serving cells is determined first, and the reference cell is the serving cell with the lowest serving cell index (number). The plurality of serving cells comprise a primary cell, a primary and secondary cell or an activated secondary cell.

After determining a reference serving cell of the plurality of serving cells, it is determined on which serving cell to transmit or receive according to the configuration or scheduling of the reference serving cell and other serving cells. Comprises the following steps:

The embodiment of the invention can be specifically realized as follows:

determining whether conflicts exist among configured Serving cells according to the actually activated Scell, and determining corresponding terminal behaviors;

and determining reference cells in each frequency band or each frequency band combination according to the actually activated Scell.

After receiving an activation or deactivation command of a certain Scell and before the maximum time delay of activation or deactivation, the UE assumes the Scell as a deactivation cell or an activation cell and determines whether uplink and downlink conflicts exist among Serving cells.

Therefore, the terminal can determine whether a plurality of serving cells conflict or not according to the activated Scell, the utilization rate of uplink and downlink resources is improved, and excessive discarding of uplink and downlink transmission is avoided. And in the activated or deactivated Scell process, using the maximum time delay as the effective time of uplink and downlink configuration of the Scell, and avoiding the ambiguity of the uplink and downlink configuration between the network equipment and the terminal.
