In the high frequency band (greater than 6GHz), due to the large attenuation of electromagnetic waves, beamforming methods are usually needed to resist the attenuation of the signal and increase the transmission distance of the signal.

In the following, examples 1 and 2 are used to illustrate how the UE sends PUSCH directly in cell 2 without a random access process when cell switching occurs. The UE’s current serving cell is cell 1, and cell 1 configures the UE’s measurement configuration. The UE reports the measurement results according to the measurement configuration. Base station 1 makes a handover decision based on the UE’s measurement results and other information. Base station 1 sends a handover request message to base station 2. Base station 2 allows the UE to switch to cell 2. Base station 2 sends a handover request feedback message to base station 1. The handover request feedback message includes the configuration information of the user terminal in cell 2. After base station 1 receives the configuration information , Sending the configuration information to the UE, and the configuration information is used by the UE to send PUSCH in cell 2.

When the signal is transmitted in beamforming, the energy of the signal is concentrated in one direction, while the energy of the signal in other directions is weak. At this time, the transmitted signal can be called a transmission beam, and the direction in which the energy is concentrated is also called the transmission beam Direction. When receiving a signal in a beamforming manner, the receiving gain of the signal in one direction can be maximized, while the receiving gain of the signal in other directions is small. At this time, the directional receiving is called the receiving beam, and the receiving gain The largest direction is also called the receive beam direction.

The uplink RS1 and the uplink RS2 have the same spatial relationship, which means that the UE sends the uplink RS1 and the uplink RS2 using the same spatial transmission filtering method. If the spatial relationship information of the uplink RS1 is the uplink RS2, the UE uses the same spatial transmission filtering method as the RS2 to send the RS1. If the spatial relationship information of the uplink RS1 is the downlink RS3, the UE uses the same spatial transmission filtering method as the received RS3 to send the RS1. Alternatively, the uplink RS1 and the downlink RS3 have the same spatial relationship, which means that the UE uses the same spatial transmission filtering method as the received RS3 to send the RS1.

In this application, the transmission beam has the same concept as the reference signal. For example, transmit beam 1 and RS1 have the same concept. Two RSs having the same transmission beam means that the two RSs have the same spatial relationship.

Example 1

In the method of this example, base station 2 sends a handover request feedback message to base station 1. The handover request feedback message includes configuration information of the user terminal in cell 2. After receiving the configuration information, base station 1 sends the The configuration information is sent to the UE.

The configuration information of the user terminal in cell 2 includes at least one of the following information: time domain resource indication information, first reference signal information, power control information, measurement reference signal information, CSI (channel state information, channel state information) Measurement configuration information, CSI request information, sounding reference signal information, and path loss reference signal information.

The time domain resource indication information indicates the OFDM symbol resources in a slot, and these OFDM symbol resources are used for PUSCH transmission. For example, using 4-bit information to indicate the OFDM symbol resources with SLIV (Start and length indicator value).

The first reference signal information includes at least one of the following: SSB (Synchronization signal block) index, CSI-RS (Channel state information reference signal, channel state information reference signal) index, SRS (Sounding reference signal, sounding reference signal) )index.

For example, if the first reference signal information is the SSB index, the UE transmits the PUSCH according to reciprocity or beam correspondence (beam correspondence). Specifically, the SSB and the PUSCH DMRS have the same spatial relationship.

For example, if the first reference signal information is a CSI-RS index, the UE transmits PUSCH according to reciprocity or beam correspondence. Specifically, the CSI-RS and the PUSCH DMRS (Demodulation Reference Signal, demodulation reference signal) have the same space relationship.

For example, if the first reference signal information is an SRS index, the SRS and the PUSCH DMRS have the same spatial relationship.

The power control information of the PUSCH may be 2-bit power control information and/or 1-bit closed-loop power control process information, such as: TPC (transmit power control) information in DCI (Downlink Control Information, downlink control information). After the UE receives the power control information sent by the base station, it will not reset the uplink power-related configuration, such as nominal power, path loss reference signal, accumulated power, etc., and continue to use the power configuration configured in cell 1 to calculate the uplink transmit power.

The information of the path loss reference signal may be an SSB index or a CSI-RS index. The UE uses the reference signal indicated by the path loss reference signal to calculate the path loss. Specifically, if the path loss reference signal information is an SSB index, the UE uses the SSB indicated by the SSB index to calculate the path loss; if the path loss reference signal is a CSI-RS index, the UE uses the CSI indicated by the CSI-RS index -RS to calculate the path loss.

The measurement reference signal information may be an SSB index or a CSI-RS index, where the CSI-RS includes periodic CSI-RS and semi-static CSI-RS, and the UE measures the corresponding SSB or CSI-RS according to the indication.

The CSI measurement configuration includes the CSI measurement resource configuration, the CSI report configuration, and the association relationship between the CSI measurement resource and the CSI report. Among them, CSI measurement resource configuration SSB and CSI-RS parameter configuration, such as time domain resources, frequency domain resources, frequency domain density, period and offset value, number of antenna ports, transmission power, CDM (code division multiplexing, code division multiplexing) Use) type, etc. CSI report configuration includes report method, report synchronization, report parameter type, frequency domain configuration, report trigger state size, etc.

The bit length of the CSI request information is related to the size of the report trigger state. The CSI request information is used to request the UE to send CSI and which configuration CSI to send. The UE receives the CSI request and sends CSI on the configured PUSCH resource.

The sounding reference signal information indicates the resource configuration of the SRS. In an embodiment, the PUSCH resource and the SRS resource have the same period, and the SRS resource and the PUSCH resource are separated by M OFDM symbols, slots or radio frames in the time domain, where M is configured by the network side. According to the configuration, the UE first sends the SRS on the SRS resource, and then sends the PUSCH. The network side measures the SRS, and according to the measurement result, selects a suitable receiving beam to receive the PUSCH sent by the UE.

Example 2

NR (New Radio) supports the configured grant (configuration authorization) configuration. The configured grant configures periodic resources. There are two activation methods for the periodic resources. One is by configuring the RRC (Radio Resource Control (Radio Resource Control) signaling is activated, and the other is that RRC signaling configures periodic resources and is activated by subsequent downlink control information DCI. Wherein, the RRC signaling for configuring periodic resources includes at least the following information: time domain resource indication, frequency domain resource indication, resource period, and repetition factor.

In the method of this example, the base station 2 sends a handover request feedback message to the base station 1. The handover request feedback message includes the user terminal's configuration authorization resource configuration information in the cell 2. After the base station 1 receives the configuration information, Send the configuration information to the UE.

The configured authorized resource configuration information of the user terminal in the cell 2 includes at least one of the following information: time domain resource information, frequency domain resource information, PUSCH repetition times, and the corresponding relationship between the first reference signal and the resource.

The number of PUSCH repetitions indicates the number of PUSCH resources in a period.

The first reference signal information includes at least one of the following: SSB (Synchronization signal block, synchronization signal block) index, CSI-RS (Channel state information reference signal, channel state information reference signal) index, SRS (Sounding reference signal, sounding reference signal) )index.

The correspondence between the first reference signal and the resource includes the correspondence between the SSB index or the CSI-RS index or the SRS index and the PUSCH resource in one period. The correspondence between the SSB and the PUSCH resource means that the SSB and the PUSCH DMRS have the same spatial relationship.

For example, the corresponding SSB index or CSI-RS index or SRS index are configured one by one according to the sequence of PUSCH resources in time. Alternatively, multiple SSBs or CSI-RSs or SRSs are configured in the configured grant, and these SSBs, CSI-RSs or SRSs are one-to-one corresponding to PUSCH resources in an index order.

In an implementation manner, the designated first reference signal information or transmission resource information used by the UE is configured in the configured grant. Wherein, the designated first reference signal information indicates the spatial relationship information of the UE sending PUSCH DMRS, the UE sends the PUSCH on the PUSCH resource corresponding to the designated first reference signal, and the PUSCH DMRS has the same spatial relationship as the designated first reference signal Wherein, the transmission resource information indicates the PUSCH resource specifically used by the UE, the UE transmits the PUSCH on the indicated PUSCH resource, and the PUSCH DMRS has the same spatial relationship with the first reference signal corresponding to the PUSCH resource.

If the first reference signal information and the transmission resource information are not configured in the configured grant, the UE selects the SSB or CSI-RS with the highest measurement result and the corresponding PUSCH resource to send the PUSCH according to the measurement result of the SSB or CSI-RS. According to the measurement result of the SSB or CSI-RS, the UE sends the PUSCH on the PUSCH resources corresponding to the SSB or CSI-RS when the measurement result of the CSI-RS or SSB is greater than a certain threshold. If the measurement results of multiple SSBs or CSI-RSs are greater than a certain threshold, the UE transmits PUSCH on multiple PUSCH resources corresponding to these SSBs or CSI-RSs. In an embodiment, the UE uses different redundancy versions to transmit PUSCH, and the used redundancy version is configured by the network side. When the RS (reference signal) type of the first reference signal information corresponding to the resource is different from the measurement RS type of the UE, the UE will determine the difference between the measured RS and the RS of the first reference signal information corresponding to the resource according to the measurement result and the resource. QCL (Quasi co-location, quasi co-location or quasi co-location) relationship is used to select a suitable transmission beam and corresponding PUSCH resource to transmit PUSCH, wherein the QCL relationship is pre-configured by the network side.

In one embodiment, the configured grant configures periodic resources, the time domain offset is configured to be 1 slot, the resource period is configured to be 8 slots, the number of repetitions is configured to be 4, and the first reference signal information is configured to be 4 SSBs, They are SSB 0~3, and the 4 SSBs are configured to correspond to the 4 PUSCH resources respectively. Then see Figure 9 for the specific resource configuration.

As shown in Figure 9, the starting resources of each cycle are slot 1, slot 9, slot 17, slot 25, and the subsequent slot with an interval of 8. The repetition factor 4 indicates 4 slots including the starting slot. It is the PUSCH resource in each cycle. These 4 slots correspond to the 4 SSB beams one-to-one, the first slot corresponds to SSB0, that is, the PUSCH of the first slot DMRS and SSB0 have the same spatial relationship, the second slot corresponds to SSB1, and the third slot corresponds to SSB2 , The fourth slot corresponds to SSB3. If the UE sends the PUSCH on slot 9, the PUSCH DMRS sent by the UE has the same spatial relationship with SSB0, and the base station uses the beam for sending SSB 0 on slot 9 to receive the PUSCH sent by the UE.

In an embodiment, the configured grant configures the UE to send the first reference signal information as SSB1, and according to the correspondence between the first reference signal information and PUSCH resources, the UE sends the PUSCH on

slots

2, 10, 18, or 26. , Its transmit beam is the receive beam when the UE receives SSB 1. When the UE does not have reciprocity, the UE sends the PUSCH in a beam scanning manner on

slots

2, 10, 18, or 26. Or, the configured grant configures the UE's transmission resource as the second PUSCH. According to the corresponding relationship between the first reference signal information and the PUSCH resource, the UE transmits the PUSCH on

slots

2, 10, 18, or 26, and its transmission beam is the UE Receive beam when receiving SSB 1. When the UE does not have reciprocity, the UE sends the PUSCH in a beam scanning manner on

slots

2, 10, 18, or 16.

In an embodiment, if the configure grant does not configure any first reference signal information and transmission resource information, the UE has the highest measurement result of SSB2, or only the measurement result of SSB2 is greater than a certain threshold, then the UE corresponds to SSB2 The PUSCH is sent on slots 3, 11, 19, 27, etc., and the sending beam is the receiving beam when the UE receives SSB2. When the UE does not have reciprocity, the UE sends the PUSCH in a beam scanning manner on these slots. If the UE’s measured reference signal is CSI-RS, CSI-RS 0-7 respectively, where CSI-

RS

0 and 1 have a QCL relationship with SSB 0, CSI-

RS

2 and 3 have a QCL relationship with SSB 1, and CSI-

RS RS

4 and 5 have a QCL relationship with SSB 2, and CSI-

RS

6 and 7 have a QCL relationship with SSB 3. Among the measurement results, the measurement result of CSI-RS 4 is the highest, or the measurement result is greater than a certain threshold. According to the QCL relationship, the UE The PUSCH is sent on the PUSCH resource corresponding to SSB2, that is, slots 3, 11, 19, 27, etc.

In an embodiment, when the corresponding relationship between the first reference signal information and the PUSCH resource is not configured in the configured grant, the resources configured in the configured grant are defaulted, and the resources in a period have a one-to-one correspondence with the actual SSB sent. The corresponding relationship is in the order of SSB index, the first SSB corresponds to the first PUSCH resource in a period, the second SSB corresponds to the second PUSCH resource in a period, and so on. The UE selects an appropriate transmission beam and PUSCH resource to transmit the PUSCH according to the corresponding relationship.

The resources configured by configure grant are shown in Figure 10, and configured grant does not configure the corresponding relationship between the first reference signal and the resource. The actual SSB sent by the network side is SSB1, SSB3, SSB4, SSB7, then the default first reference signal and resource The corresponding relationship is: SSB1 corresponds to the first resource in a period, SSB3 corresponds to the second resource in a period, SSB4 corresponds to the third resource in a period, and SSB7 corresponds to the fourth resource in a period.

In an embodiment, the UE reports the beam-level measurement results of the N RSs. In the resource configuration, the network side configures N PUSCH resources, and the N PUSCH resources have a one-to-one correspondence with the N RSs. In one embodiment, the first PUSCH resource in time corresponds to the RS with the highest beam-level measurement result, the second PUSCH resource in time corresponds to the RS with the second highest beam-level measurement result, and so on.

In an implementation manner, the network side uses RRC signaling to configure multiple sets of configured grant resources, and the multiple sets of configured grant resources are all the same except for the time domain resource configuration, redundancy version, and SRS resource indication. Or, some parameters in the configured grant configuration in a certain set are not configured, then the parameter values that are not configured are the same as the parameter values of the same type in a certain set of configured grant configurations.

In an embodiment, the corresponding relationship between the first reference signal and the resource is configured in the configured grant, where the first reference signal information includes at least SSB and/or CSI-RS, if all the configured SSB or CSI-RS measurement results are Less than a certain threshold and/or less than the signal quality measurement result of a certain SSB other than the configured SSB or a CSI-RS other than the configured CSI-RS, the UE does not send PUSCH on these configured PUSCH resources , Use random access method to access the cell. The threshold is notified by the network side or pre-defined by the agreement.

As shown in Figure 11, the configured grant configures 4 SSBs (SSB0, SSB1, SSB2, SSB3) and the corresponding resources. During the UE measurement, the measurement results of SSB0～SSB3 are all less than a certain threshold, so the UE is not in these configurations It is sent on the PUSCH, but the random access method is used to access the cell. Or the measurement results of SSB0 to SSB3 are all less than the measurement results of SSB4, and the UE uses SSB4 to access the cell according to the random access method.

As shown in Figure 12, the UE stays connected to cell 1 and cell 2 at the same time. Both cells have uplink and downlink transmissions. The services transmitted include URLLC (Ultra Reliable Low Latency Communication) and eMBB (Ultra Reliable Low Latency Communication). Enhanced mobile broadband, at least one of enhanced mobile broadband).

Example 4

In this example, the UE maintains a connection with cell 1 and cell 2 at the same time, both of which have uplink and downlink transmissions, and the transmitted services include at least one of URLLC and eMBB. Cell 1 configures the PUCCH resources of the URLLC service for the UE. The UE sends PUCCH on these PUCCH resources to cell 1, and the UE sends the resource information that overlaps the PUCCH resources in cell 2 in time to cell 2, or cell 1 configures Cell 2 is notified of the PUCCH resources of cell 2, and cell 2 judges which resources will overlap with PUCCH resources of cell 1, and cell 2 will not schedule the uplink transmission of the UE on these overlapping resources, that is, the UE does not expect cell 2 to have overlapping resources Up scheduling uplink.

As shown in Figure 13, the PUCCH of cell 1 occupies the fourth OFDM symbol and the 11th OFDM symbol in a slot, and the second, third, ninth, and tenth OFDM symbol of a slot in cell 2 There is overlap with the PUCCH resource of cell 1, and the UE reports the four overlapping OFDM symbol information to cell 2. Then cell 2 cannot schedule the UE's uplink on these four OFDM symbols, including at least PUSCH transmission, PUCCH transmission, PRACH ( Physical Random Access Channel, physical random access channel) transmission, SRS transmission, PTRS (Phase tracking reference signal, phase tracking reference signal) transmission, that is, the UE does not expect to transmit PUSCH, PUCCH, PRACH, SRS on these four OFDM symbols , At least one of PTRS.

Example 5

In this example, the UE maintains a connection with cell 1 and cell 2 at the same time, both of which have uplink and downlink transmissions, and the transmitted services include at least one of URLLC and eMBB. Cell 1 configures PUCCH resources for the UE, and cell 2 configures PUCCH resources for the UE. If the UE has UCI (Uplink Control Information) sent on the PUCCH resource of cell 1, then the UE carries the UCI on the PUCCH resource of cell 2. The PUCCH resource of cell 2 is not earlier than the PUCCH resource of cell 1 in time and is closest to the PUCCH resource of cell 1 in time. The PUCCH in cell 1 cancels transmission.

As shown in Figure 14, the PUCCH resources of cell 1 are even-numbered OFDM symbols in a slot, the PUCCH resources in slot 0 are denoted as a to g, and the PUCCH resources in cell 2 are even-numbered in a slot. For OFDM symbols, the PUCCH resources in slot 1 are denoted as A to G. In all the PUCCHs in cell 2, PUCCH B is not earlier than PUCCH c of cell 1 in time and is closest to PUCCH c of cell 1, so the UCI originally to be carried on PUCCH c of cell 1 is carried on PUCCH B of cell 2 The PUCCH c of cell 1 is canceled.

Example 6

The UE maintains a connection with cell 1 and cell 2 at the same time, both of which have uplink and downlink transmissions, and the transmitted services include at least one of URLLC and eMBB. Cell 1 configures PUCCH resources for the UE, and cell 2 configures PUCCH resources for the UE. The PUCCH resource in the cell 1 is mapped to the PUCCH resource in the cell 2. The specific mapping method is that the PUCCH in the cell 1 is mapped to the PUCCH resource in the cell 2 that is not earlier than the PUCCH in time and is closest in time to the PUCCH. If there is UCI to be sent on a PUCCH of cell 1, according to this mapping relationship, the UCI to be sent on this PUCCH is carried on the corresponding PUCCH of cell 2 and sent, and the PUCCH of cell 1 is cancelled. When multiple PUCCHs of cell 1 are mapped to the same PUCCH of cell 2, the UCIs of the multiple PUCCHs are cascaded together. In an implementation manner, among multiple PUCCHs in cell 1, if there is a PUCCH without ACK/NACK feedback, the UE generates a NACK for this PUCCH. After receiving the PUCCH sent by the UE, cell 2 forwards the UCI carried by the PUCCH to cell 1.

In an implementation manner, the UE reports the mapping relationship between the PUCCHs of cell 1 and cell 2 to cell 1 or cell 2. Specifically, the UE reports the offset value between PUCCHs with corresponding relationships to cell 1 or In cell 2, the number of reported offset values is equal to the number of PUCCH resources of cell 1 or cell 2. If the UE reports the mapping relationship to cell 1, when cell 2 forwards the UCI sent by the UE, it needs to forward PUCCH resources, especially time domain resources, such as the SFN (System frame number) number and slot of the PUCCH. Number, OFDM number. If the UE reports the mapping relationship to cell 2, after receiving the PUCCH sent by the UE, cell 2 obtains the PUCCH resource location information of the UCI in cell 1 according to the mapping relationship, and forwards the information and UCI to cell 1.

As shown in Figure 15, the PUCCH resource of cell 1 is an even-numbered OFDM symbol in a slot. The PUCCH resources in slot 0 are denoted as a~g, and the first 4 PUCCH resources in slot 1 are denoted as h~ k; OFDM#2, #6, and #10 in each slot in cell 2 are PUCCH resources, where the last PUCCH in slot 0 is marked as A, and the three PUCCH resources in slot 1 are marked as B～D, slot 2 The first PUCCH is marked as E. The PUCCH a of cell 1 and the PUCCH A of cell 2 have the same starting time, so PUCCH A is not earlier than PUCCH a in time and is closest to PUCCH a, so PUCCH a of cell 1 is mapped to PUCCH A of cell 2. For PUCCH b of cell 1, PUCCH B in cell 2 is not earlier than PUCCH b in time and nearest to PUCCH b, so PUCCH b is mapped to PUCCH B. Similarly, PUCCH c and d are mapped to PUCCH B, PUCCH e and f are mapped to PUCCH C, PUCCH g and h are mapped to PUCCH D, and PUCCH i, j and k are mapped to PUCCH E. If there is UCI to be sent on PUCCH b, c, d, and 1 bit NACK is sent on PUCCH b, 1 bit ACK is sent on PUCCH c, and 1 bit ACK is sent on PUCCH d, then the UCI on the three PUCCHs are concatenated to get 011. Then the bearer is sent on PUCCH B. If there is UCI to be sent on PUCCH c, but no UCI is sent on PUCCH b and d, then NACK is generated on PUCCH b and d, and the generated NACK is concatenated with the UCI of PUCCH c, and carried on PUCCH B and sent. If the ACK/NACK of one TB (Transport Block) is fed back on PUCCH c, then a 1-bit NACK is generated on PUCCH b and d; if the ACK/NACK of two TBs is fed back on PUCCH c, then PUCCH A 1-bit NACK is generated on each of b and d.

The offset value between PUCCH a and PUCCH A is 10 OFDM symbols; the offset value between PUCCH b and PUCCH B is 14 OFDM symbols; the offset value between PUCCH c and PUCCH B is 12 OFDM symbols ; The offset value between PUCCH d and PUCCH B is 10 OFDM symbols, and the OFDM symbol number of PUCCH corresponding to PUCCH b, c, d is 2; the offset value between PUCCH e and PUCCH C is 12 OFDM symbol; the offset value between PUCCH f and PUCCH C is 10 OFDM symbols, and the PUCCH OFDM symbol number corresponding to PUCCH e and f is 6; the offset value between PUCCH g and PUCCH D is 12 OFDM symbol, and the OFDM symbol number of the PUCCH corresponding to PUCCH a and g is 10.

The UE reports the 7 offset values and the OFDM symbol number of the PUCCH in cell 2 corresponding to the 7 PUCCHs in a slot to cell 1. The UE sends PUCCH B to cell 2, and cell 2 sends the UCI carried in PUCCH B Forward to cell 1, and notify cell 1 of PUCCH SFN number #0, slot number #1, and OFDM symbol number #2. After cell 1 receives the information sent by cell 2, according to the OFDM symbol number, the OFDM symbol number of the PUCCH corresponding to cell 1 of the UCI is #2, #4, #6, and then the PUCCH offset value is used to obtain the cell 2 The sent UCI corresponds to the PUCCH of cell 1 as SFN#0, and the PUCCH on slot#0.

The UE reports these 7 offset values and the OFDM symbol number of the PUCCH in cell 2 corresponding to the 7 PUCCHs in a slot to cell 2. The UE sends PUCCH B to cell 2, the SFN number of PUCCHB is 0, and the slot number is Is 1, the OFDM symbol number is 2, cell 2 obtains the PUCCH corresponding offset

value

14, 12, 10 according to the OFDM number, and cell 2 obtains the PUCCH B corresponding to the PUCCH in cell 1 as the SFN number according to these offset values It is 0, the slot number is 0, and the OFDM symbol numbers are 2, 4, and 6, respectively, and then the resource information of the three PUCCHs and UCI are sent to cell 1.

Example 7

This example is described on the basis of Example 5, the method of calculating the offset value when the subcarrier spacing of cell 1 and cell 2 are different.

When the sub-carrier spacing of cell 1 and cell 2 are different, according to the multiple relationship of the sub-carrier spacing of the two cells, multiply the slot number and OFDM number of the cell with the small sub-carrier spacing by the multiple of the sub-carrier spacing, and then follow Example 5 Method to calculate the offset value.

As shown in Figure 16, the sub-carrier spacing of cell 1 is 30k, the even-numbered OFDM symbols in a slot are PUCCH resources, the sub-carrier spacing of cell 2 is 15k, and the sub-carrier spacing in a slot is 2, 5, 8, 11 OFDM symbols are PUCCH resources. The subcarrier spacing multiple of the two cells is 2, then the slot number and OFDM symbol number of cell 2 are multiplied by 2, and then the offset value between the PUCCH resources with the mapping relationship is calculated. The four offsets shown in the figure are The shift value is 26 OFDM symbols.

Example 8

In this example, the UE maintains a connection with cell 1 and cell 2 at the same time, both of which have uplink and downlink transmissions, and the transmitted services include at least one of URLLC and eMBB. Cell 1 configures PUCCH resources for the UE, and cell 2 configures PUCCH resources for the UE. The UCI to be transmitted on the PUCCH in cell 1 is carried on the PUCCH of cell 2, where the PUCCH transmission time of cell 2 is not earlier than the PUCCH transmission time of cell 1, and is closest in time to the PUCCH transmission time of cell 1. If the PUCCH of cell 2 does not have the UCI of cell 2, then the PUCCH of cell 2 only sends the UCI of cell 1; if the PUCCH of cell 2 has the UCI of cell 2, then the UCI of cell 1 is cascaded after the UCI of cell 2. If the UCI of multiple PUCCHs in cell 1 is carried on the same PUCCH of cell 2, then the UCIs of multiple PUCCHs in cell 1 are concatenated in order.

As shown in Figure 17, for PUCCH A of cell 1, the transmission time of PUCCH a in cell 2 is not earlier than the transmission time of PUCCH A, and is closest in time to the transmission time of PUCCH A. Therefore, the UCI of PUCCH A is carried in Send on PUCCH a.
