The uplink transmission method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

Referring to fig. 2, fig. 2 is a flowchart of an uplink transmission method provided in an embodiment of the present application, where the method is used for a terminal, and as shown in fig. 2, the method includes the following steps:

step 101, when a PUCCH and at least one PUSCH are overlapped in a time domain and the at least one PUSCH includes a PUSCH enabling uplink transmission skip, transmitting uplink control information UCI on one channel of the PUCCH and the at least one PUSCH; wherein a time interval between a starting symbol of an earliest channel of the PUCCH and the at least one PUSCH and an ending symbol of a corresponding first downlink transmission channel (or referred to as a first downlink channel) is greater than or equal to a sum of an uplink multiplexing processing time and a first spreading time, and the first spreading time includes at least 1 time domain symbol.

If a Physical Uplink Control Channel (PUCCH) and a Physical Uplink Shared Channel (PUSCH) that need to transmit Uplink Control Information (UCI) overlap in a time domain, the base station may meet a condition of UCI multiplexing processing time of the terminal when scheduling the PUSCH, so that the UCI may be multiplexed on the PUSCH, and simultaneous transmission of the PUCCH is avoided.

The embodiment of the invention considers the uplink transmission skipping function, increases the multiplexing processing time and avoids the transmission failure caused by insufficient processing time. That is, in the case where a PUCCH overlaps with at least one PUSCH in a time domain and the at least one PUSCH includes a PUSCH enabling uplink transmission skip, uplink control information UCI is transmitted on one channel of the PUCCH and the at least one PUSCH. Wherein one channel in the PUCCH and the at least one PUSCH is understood as a target channel. The target channel may be PUCCH or PUSCH, which may be different according to a policy.

Regardless of whether the target channel is PUCCH or PUSCH, due to the control of the multiplexing processing time of the channel, the time interval between the start symbol of the target channel and the end symbol of the corresponding first downlink transmission resource is greater than or equal to the sum of the uplink multiplexing processing time and the first extension time, sufficient to guarantee normal transmission of UCI.

In this embodiment, a time interval between a starting symbol of an earliest channel in the PUCCH and the at least one PUSCH and an ending symbol of a corresponding first downlink transmission channel is greater than or equal to a sum of an uplink multiplexing processing time and a first extended time, and the time interval is set to be larger by the first extended time, so that a problem that the processing time is insufficient when the terminal multiplexes and transmits UCI on one channel in the PUCCH and the at least one PUSCH is avoided.

In the specific embodiment of the present invention, the downlink transmission channels corresponding to the PUCCH and the at least one PUSCH are different. For the PUCCH, the downlink transmission channel corresponding to the PUCCH is the PDSCH corresponding to the HARQ-ACK transmitted by the PUCCH, or the PDCCH scheduling the PUCCH, and for the PUSCH, the downlink transmission channel corresponding to the PUSCH is the PDCCH scheduling the PUSCH, which is further described below.

That is, the corresponding first downlink transport channel is: scheduling a Physical Downlink Control Channel (PDCCH) of the at least one PUSCH, or scheduling the PDCCH of the PUCCH, where the uplink multiplexing processing time is a maximum value of the multiplexing preparation time of the at least one PUSCH; that is, the first symbol of the earliest PUCCH or PUSCH in the PUCCH and the at least one PUSCH is not earlier than the symbol after the interval of the uplink multiplexing processing time and the first spreading time after the last symbol of any one PDCCH in the PDCCHs corresponding to the scheduled PUCCH and the at least one PUSCH.

Or

The corresponding first downlink transmission channel is: all Physical Downlink Shared channels (PDSCH for short) corresponding to the UCI, where the UCI carries HARQ-ACK information of the PDSCH, and the uplink multiplexing processing time is a maximum value of multiplexing processing times of all PDSCHs corresponding to the UCI. That is, the first symbol of the earliest PUCCH or PUSCH in the PUCCH and the at least one PUSCH is not earlier than the symbol after the interval uplink multiplexing processing time and the first spreading time after the last symbol of any associated PDSCH, and HARQ-ACK transmission of the associated PDSCH is on the overlapped PUCCH or PUSCH.

In the specific embodiment of the present invention, the scheduling of the PDCCH of the PUCCH includes: and a PDCCH for carrying Downlink Control Information (DCI) corresponding to the PUCCH. That is, the first symbol of the earliest PUCCH or PUSCH in the PUCCH and the at least one PUSCH is not earlier than the symbol after the interval uplink multiplexing processing time and the first spreading time after the last symbol of any associated PDSCH, and HARQ-ACK transmission of the associated PDSCH is on the overlapped PUCCH or PUSCH.

As shown in fig. 3a, the corresponding first downlink transport channel is: and scheduling the PDCCH of the PUCCH. In fig. 3a, reference sign a is a starting symbol of an earliest channel in the PUCCH and the at least one PUSCH, and in fig. 3a, the starting symbol of the PUCCH is earlier than the starting symbol of the at least one PUSCH; reference symbol C denotes an end symbol of the PDCCH carrying the DCI corresponding to the PUCCH.

As shown in fig. 3b, the corresponding first downlink transport channel is: scheduling transmission resources of the PDCCH of the at least one PUSCH, wherein reference sign a in fig. 3b is a starting symbol of an earliest channel in the PUCCH and the at least one PUSCH, and in fig. 3b, the starting symbol of the at least one PUSCH is earlier than the starting symbol of the PUCCH; reference symbol B is an end symbol of a transmission resource of the PDCCH scheduling the at least one PUSCH.

In this embodiment, the uplink multiplexing processing time is a maximum value of the multiplexing preparation time of the at least one PUSCH.

Several concepts of specific embodiments of the invention are described below.

Uplink multiplexing processing time:

when a single-slot PUCCH overlaps with a single-slot PUCCH or PUSCH, the UE multiplexes all UCI on one PUCCH or PUSCH using the existing multiplexing rule, and if there are multiple PUSCHs/PUCCHs overlapping,

maximum value of uplink multiplexing processing time for all PDSCHs, i.e. maximum value of uplink multiplexing processing time for all PDSCHs

The uplink multiplexing processing time of the ith PDSCH is as follows:

wherein d is_1,1In relation to the DMRS configuration, PDCCH and PDSCH configuration, in FIG. 3c, T1 is

Maximum value of uplink multiplexing processing time for all PUSCHs, i.e.

The uplink multiplexing processing time of the ith PUSCH is as follows:

in FIG. 3d, T2 is

In an embodiment of the present invention, the transmission of the UCI may select the channel according to different strategies, which is described as follows.

In an embodiment of the present application, before transmitting uplink control information UCI on one of the PUCCH and the at least one PUSCH, the method further includes:

under the condition that the MAC layer corresponding to the PUSCH to be multiplexed currently by UCI does not generate MAC PDU, multiplexing the UCI into the at least one PUSCH, wherein the corresponding MAC layer comprises the target PUSCH of the MAC PDU; .

Or

Multiplexing the UCI into the at least one PUSCH, wherein a corresponding MAC layer comprises a target PUSCH of the MAC PDU; .

Or

And mapping the UCI to the PUCCH under the condition that the MAC layer corresponding to the at least one PUSCH does not generate the MAC PDU.

This is further exemplified as follows.

Under the condition that the MAC PDU is not generated on the MAC layer corresponding to the PUSCH to be multiplexed currently by the UCI, multiplexing the UCI into the PUSCH, wherein the corresponding MAC layer generates filling bits to be multiplexed with the UCI; (UCI send policy one).

Multiplexing the UCI into the PUSCH, wherein a corresponding physical layer generates virtual bits (dummy bits) to be multiplexed with the UCI; (UCI transmission policy two).

And mapping the UCI to the PUCCH under the condition that the MAC layer corresponding to the at least one PUSCH does not generate the MAC PDU. (UCI Transmission strategy three).

Corresponding to the UCI sending strategy one, under the condition that the MAC layer corresponding to the PUSCH to be multiplexed currently by the UCI does not generate the MAC PDU, the UE informs the MAC layer to generate the MAC PDU: the increased first spreading time can be used for the UE multiplexing process change and the MAC layer to generate padding bits.

In the first strategy, the physical layer of the UE firstly performs a UCI multiplexing related procedure, and determines whether UCI is multiplexed on the PUSCH of the carrier, and if UCI is multiplexed on the PUSCH of the carrier, the UE notifies the MAC layer to generate the PDU. That is, the UCI multiplexing procedure of the UE is changed, requiring additional processing time.

Corresponding to a UCI sending strategy II, under the condition that an MAC PDU is not generated on an MAC layer corresponding to a PUSCH to be multiplexed currently by UCI, a physical layer of the UE generates a virtual bit and multiplexes the virtual bit with the UCI; the increased first spreading time can then be used for the physical layer to generate virtual bits.

In the second strategy, the physical layer uses the virtual bit as the PUSCH multiplexing UCI, and the increased first extension time can be used for the change of the UE multiplexing process and the time for the physical layer to generate the virtual bit.

In the two strategies, the processing time for the UE to perform PUSCH multiplexing is as follows: assuming that the ith PDCCH schedules the PUSCH of that carrier, the starting symbol time interval from the last symbol of that PDCCH to the earliest UL transmission in all overlapping PUCCH/PUSCHs of the group containing the carrier PUSCH is:

Δ_x3the value is a value predefined in a protocol or a value related to the UE capability, and may also be related to MAC PDU generation time, carrier switching time, virtual bit generation time, and the like, and reported to the network side device by the UE.

If the UE has an ith PDSCH on that carrier with UCI (e.g., corresponding HARQ-ACK) belonging to the group containing the carrier PUSCH, then the last symbol of the ith PDSCH is spaced from the start symbol of the earliest UL transmission in all overlapping PUCCH/PUSCHs in that group by:

Δ_x4and reporting the value predefined in the protocol or the value related to the UE capability to the network side equipment by the UE.

Wherein, Delta_x3，Δ_x4A value of 0 or more, for example, may be a plurality of symbols, Δ, such as 1, 2, 3, 4_x3，Δ_x4I.e. the first extension time described above.

The present case may be applied to only carriers configured with uplink transmission skip but not to carriers not configured with uplink transmission skip, that is, the newly defined processing time is only applied to carriers configured with uplink transmission skip, or once one carrier has uplink transmission skip configured, the present case will be applied to all carriers, that is, the newly defined processing time is applied to all carriers.

In the embodiment of the present invention, if, according to some multiplexing strategies, the PUSCH for multiplexing UCI transmission is a PUSCH skipped by uplink transmission, and the MAC layer has no PDU, in order to ensure normal transmission of UCI, the service data in the PUSCH for transmitting UCI is generated virtual data or padding data generated by the MAC layer.

Specific examples are as follows.

If the MAC layer has no data, a padding bit (padding bit) is used for generating the PDU, if the MAC of a Carrier unit (CC) 1 and CC2 has no data, the network schedules the PUSCH of the CC1, and according to a certain strategy, if UCI is multiplexed on the PUSCH of the CC1, the padding bit is used for generating the PDU even if the MAC layer has no data.

In this case, the time interval from scheduling DCI of one PUSCH to the starting symbol of the PUSCH (i.e., the processing time required for the UE to prepare the PUSCH) on the carrier where the uplink transmission skip is configured is:

T_proc,2+d_x1，d_x1the UE reports the value predefined in the protocol or the value related to the UE capability to the network side device.

For the carrier configured with uplink transmission skip, the time interval between the scheduled PDSCH tail symbol and the PUCCH starting symbol corresponding to the HARQ-ACK bearer of the PDSCH is as follows:

T_proc,1+d_x2，d_x2a value predefined in a protocol or a value related to the UE capability and reported to the network side equipment by the UE, d_x1、d_x2Can be considered as a second extended time.

Or, the physical layer virtual bit of the UE is used as PUSCH transmission, and the UCI is multiplexed onto the PUSCH.

The processing time for the UE to perform PUSCH multiplexing, assuming that the ith PDCCH schedules PUSCH, and the time interval from the last symbol of the PDCCH to the start symbol of the earliest UL transmission in all overlapping PUCCH/PUSCH groups including the PUSCH is as follows:

Δ_y3the value is predefined in the protocol or a value related to the UE capability, and is reported to the network side device by the UE.

For the ith PDSCH, whose UCI (e.g., corresponding HARQ-ACK, Hybrid Automatic Repeat reQuest (HARQ)) belongs to a group containing one PUSCH/PUCCH, the last symbol of the ith PDSCH is spaced from the start symbol of the earliest UL transmission in all overlapping PUCCH/PUSCH within the group by:

Δ_y4the value is predefined in the protocol or a value related to the UE capability, and is reported to the network side device by the UE.

Wherein, Delta_y3，Δ_y4Can be regarded as a first spreading time, Δ_y3，Δ_y4The value is 0 or more, and may be, for example, a plurality of symbols such as 1, 2, 3, 4, or the like. The requirements are satisfied: in a group from the ending symbol of any PDSCH of the UE to the PUCCH of HARQ-ACK transmission of the UE, the time interval of the starting symbol of the earliest PUCCH/PUSCH in all PUCCH/PUSCHs overlapped with the PUCCH is

As the maximum value of the processing time of all PDSCHs, i.e.

Meanwhile, the time interval from the end symbol of any PDCCH to the start symbol of the earliest PUCCH/PUSCH in the scheduled overlapped PUCCH/PUSCHs is

Is the maximum value of the processing time of all PUSCHs, i.e.

T_proc,2+d_y1，d_y1a value predefined in a protocol or a value related to the UE capability and reported to the network side equipment by the UE, d_y1Can be regarded as the second extended time, as shown in FIG. 3f, T4 is T_proc,2And the downlink scheduling time is the preparation time of the PUSCH.

For the carrier configured with uplink transmission skip, the time interval between the scheduled PDSCH tail symbol and the PUCCH starting symbol corresponding to the HARQ-ACK scheduling of the PDSCH is as follows:

T_proc,1+d_y2，d_y2a value predefined in a protocol or a value related to the UE capability and reported to the network side equipment by the UE, d_y2Can be regarded as the second extended time, as shown in FIG. 3e, T3 is T_proc,1And the downlink scheduling time is the processing time of the PDSCH.

And mapping the UCI to the PUCCH under the condition that no MAC PDU is generated by the MAC layer corresponding to the at least one PUSCH, namely, the UCI is not transmitted by multiplexing the PUSCH, but is directly transmitted by the PUCCH.

For the third transmission strategy, as long as there is one carrier configured with uplink transmission skip, the UE first needs to notify the MAC layer to generate MAC PDU, and then multiplexes UCI to the corresponding carrier according to the multiplexing rule, so that new UE processing capability needs to be defined.

For example, in the case that the CC1 configures uplink transmission skip and the CC2 does not configure uplink transmission skip:

if the CC2 generates PDUs, the CC1 does not generate PDUs, UCI will be multiplexed to PUSCH of CC 2;

if the CC1 MAC generates PDU and the CC2 MAC does not, UCI will be multiplexed to PUSCH of CC 1;

if the CC1 and the CC2 MAC generate PDUs, the UCI determines the PUSCH multiplexed to which CC according to the multiplexing rule;

if none of the CC1, CC2 MAC generate PDUs, UCI will be transmitted using PUCCH.

Therefore, it may be necessary to introduce more processing time since the MAC layer is informed of the PDU generation and UCI multiplexing procedure change.

It should be understood that the meaning of dummy data in the embodiments of the present invention is data that needs to be transmitted on PUSCH and is not generated based on actual traffic requirements.

The processing time of the UE for PUSCH multiplexing, assuming that the ith PDCCH schedules PUSCH of the carrier, the time interval from the last symbol of the PDCCH to the start symbol of the earliest UL transmission in all overlapping PUCCH/PUSCH of the group containing PUSCH of the carrier is:

Δ_z3and reporting the value predefined in the protocol or the value related to the UE capability to the network side equipment by the UE.

Δ_z4and reporting the value predefined in the protocol or the value related to the UE capability to the network side equipment by the UE.

Wherein, Delta_z3，Δ_z4A value of 0 or more, for example, may be a plurality of symbols, Δ, such as 1, 2, 3, 4_z3，d_z4Can be considered as a first extended time.

In this embodiment, for the carrier configured with the uplink transmission skip, the time interval from the DCI scheduling for the PUSCH to the starting symbol of the PUSCH (i.e., the processing time required for the UE to prepare the PUSCH) is:
