Description

Method, device, electronic equipment and storage medium for transmitting HARQ-ACK information

Technical Field

The present application relates to the field of wireless communication technologies, and in particular, to a method, an apparatus, an electronic device, and a storage medium for transmitting HARQ-ACK information.

Background

The long Term Evolution (L TE, &lttttranslation = 'L' &tttl &ltt/t &gttong Term Evolution) technology supports two Duplex modes of frequency Division Duplex (FDD, frequency Division Duplex) and Time Division Duplex (TDD, Time Division Duplex). fig. 1 is a frame structure diagram of a L TE TDD system, each radio frame is 10 milliseconds (ms) and is divided into two half frames of 5ms, each half frame includes 8 slots of 0.5ms and 3 special fields of 1ms together, each two consecutive slots constitute one subframe, each 3 special fields constitute one special subframe, and each 3 special fields are downlink pilot slots (DwPTS, downlink pilot slots), Guard intervals (GP, Guard slots) and Uplink pilot slots (UpPTS, Uplink slots).

Transmissions in a TDD system include: transmissions from a base station to a User Equipment (UE) (referred to as downlink) and transmissions from the UE to the base station (referred to as uplink). Based on the frame structure shown in fig. 1, 10 subframes are shared by uplink and downlink within 10ms, each subframe is configured to either uplink or downlink, the subframe configured to uplink is referred to as an uplink subframe, and the subframe configured to downlink is referred to as a downlink subframe. The TDD system supports 7 uplink and downlink configurations, as shown in table 1, D represents a downlink subframe, U represents an uplink subframe, and S represents the above-mentioned special subframe including 3 special fields.

Table 1: TDD uplink and downlink configuration

The subcarrier space of an Orthogonal Frequency Division Multiplexing (OFDM) symbol may be 15kHz, 30kHz, 60kHz, 120kHz, etc., and the subcarrier space and the length of a slot may be different, and the correspondence between the subcarrier space configuration and the slot length is shown in table 2.

Table 2: corresponding relation between subcarrier space configuration mu and time slot length

μ	Time slot length (ms)	Number of OFDM symbols per slot
			0	1	14
1	0.5	14
			2	0.25	14
3	0.125	14
			4	0.0675	14

HARQ-ACK (Hybrid Automatic Retransmission Request Acknowledgement) information of the PDSCH (Physical Downlink Shared Channel) may be transmitted in the PUSCH (Physical Uplink Shared Channel) or PUCCH (Physical Uplink Control Channel). Each PDSCH of each downlink subframe is allocated with one PUCCH resource feedback HARQ-ACK feedback information in the PUCCH subframe.

For the timing relationship between the PDSCH and the PUCCH, assuming that the UE feeds back HARQ-ACK feedback information on the PUCCH of the uplink subframe n, the PUCCH indicates the PDSCH in the Downlink subframe n-k or indicates HARQ-ACK feedback information generated by a PDCCH (Physical Downlink Control Channel)/ePDCCH (Enhanced PDCCH, Enhanced Physical Downlink Control Channel) released by Semi-persistent scheduling (SPS), and the timing relationship k from the PDSCH to the PUCCH for transmitting HARQ-ACK generated by the PDSCH is referred to as HARQ (Hybrid automatic retransmission Request) timing relationship.

As described above, since the subcarrier spaces are different, the lengths of the slots may also be different, and if the HARQ timing relationship is still directly adopted to transmit HARQ-ACK information, the transmission effect may be affected, and some resources may be wasted.

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

An embodiment of the present application provides a method for transmitting HARQ-ACK information, and as shown in fig. 2, the method includes:

step S201: and the terminal determines the time unit of the PUCCH for transmitting the HARQ-ACK according to the time slot length of the time slot in which the PUCCH for transmitting the HARQ-ACK is positioned and the number of the PUCCHs in the time slot.

Step S202: and the terminal transmits the HARQ-ACK information based on the determined time unit of the PUCCH for transmitting the HARQ-ACK and the corresponding HARQ timing relation.

In the embodiment of the present application, step S201 includes any one of the following situations:

(1) when only one PUCCH is used for transmitting the HARQ-ACK in one slot, the length of one slot is determined as a time unit in which the PUCCH for transmitting the HARQ-ACK is located.

Specifically, when only one PUCCH is used to transmit HARQ-ACK in one slot, for example, the PUCCH transmitting HARQ-ACK generated by PDSCH is transmitted in slot n, and one slot length is determined as the time unit in which the PUCCH transmitting HARQ-ACK is located, that is, the slot length of PUCCH transmitting HARQ-ACK is used as the time unit in the HARQ timing relationship, then PDSCH is transmitted in slot n-k1, and k1 is referred to as PDSCH and HARQ feedback timing value (PDSCH-to-HARQ-feedback timing value) or HARQ timing relationship, and in practical application, the value of HARQ timing relationship (k1 value) is indicated by a field in PDCCH that schedules PDSCH.

(2) When more than one PUCCH is used for transmission of HARQ-ACK for one slot, a portion of one slot is determined as a time unit in which the PUCCH for transmission of HARQ-ACK is located.

There may be multiple PUCCHs per slot transmitting the dynamically scheduled PDSCH, SPS PDSCH or HARQ-ACK of the PDCCH indicating SPS release, e.g., as shown in fig. 3, in slot n there are two PUCCHs transmitting the HARQ-ACK, PUCCH-1 and PUCCH-2 respectively.

When more than one PUCCH is used for transmission of HARQ-ACK in a slot, the HARQ timing relationship k1 cannot use only the slot length of the PUCCH transmitting the HARQ-ACK as a time unit, since it cannot be distinguished which PUCCH in the slot transmits the HARQ-ACK, and one method may indicate the HARQ timing relationship in this case, i.e. determine a part of a slot as the time unit in which the PUCCH transmitting the HARQ-ACK is located.

Specifically, the HARQ timing relationship k1 has a part of one slot as a time unit. For example, as shown in FIG. 4, there are two PUCCHs in one slot for transmission of HARQ-ACK, k1 may be a time unit of half slot, PDSCH-1 is transmitted in the nth half slot, PDSCH-2 is transmitted in the n +1 th half slot, HARQ-ACK generated by PDSCH-1 is transmitted in PUCCH-1 in the n +6(k1 is 6) half slot, and HARQ-ACK generated by PDSCH-2 is transmitted in PUCCH-2 in the n +8(k1 is 7) half slot.

(3) When more than one PUCCH is used for transmitting the HARQ-ACK in one time slot, determining the length of one time slot as the time unit of the PUCCH for transmitting the HARQ-ACK, and receiving indication information for indicating that the HARQ-ACK is transmitted on the specific PUCCH in the time slot for transmitting the HARQ-ACK, which is determined according to the time unit of the length of one time slot.

When more than one PUCCH is used for transmitting HARQ-ACK in a slot, the HARQ timing relationship k1 cannot use only the slot length of the PUCCH transmitting HARQ-ACK as a time unit, because it cannot distinguish which PUCCH in the slot transmits HARQ-ACK, and another method may indicate the HARQ timing relationship in the case that one slot length is determined as the time unit in which the PUCCH transmitting HARQ-ACK is located, and receive indication information for indicating that HARQ-ACK is transmitted on a specific PUCCH in the slot transmitting HARQ-ACK determined according to the one slot length as the time unit.

Specifically, the HARQ timing relationship k1 takes one slot as a time unit, since each slot has multiple PUCCHs to transmit HARQ-ACK, and therefore, another timing relationship indication information is also needed to indicate which PUCCH in the slot transmits HARQ-ACK, so that the timing relationship indication information has two parts, the first part indicates the slot of HARQ-ACK transmission, the second part indicates which PUCCH in the slot transmits HARQ-ACK, and the second part can also be determined by the resource indication of HARQ-ACK. For example, there are two PUCCHs for transmission of HARQ-ACK in one slot, k1 is time unit of slot, as shown in FIG. 5, PDSCH-1 is transmitted in the nth slot, HARQ-ACK generated by PDSCH-1 is transmitted in PUCCH in n +3(k1 is 3) slot, and slot n +3 has two PUCCHs, PUCCH-1 and PUCCH-2, respectively, and the second part indication information indicates PUCCH-2 in the slot.

Since the subcarrier spatial configuration may be different in different serving cells and at different times of the same serving cell, the length of the slot may be different, and in addition, the subcarrier spatial configuration of the PUCCH transmitting the HARQ-ACK and the subcarrier spatial configuration of the PDSCH generating the HARQ-ACK may also be different, and then the slot length of the PUCCH transmitting the HARQ-ACK and the slot length of the PDSCH generating the HARQ-ACK may also be different, as shown in fig. 6.

In the embodiment of the present application, after determining a part of one slot as a time unit of the PUCCH in which the HARQ-ACK is transmitted, that is, when the HARQ timing relationship of step S201 is indicated by the above case (2), the HARQ timing relationship k1 takes the part of one slot as the time unit. For example, as shown in fig. 4, if there are two PUCCHs in one slot to transmit HARQ-ACK, then k1 may be a time unit in half slot, PDSCH-1 is transmitted in the nth half slot, PDSCH-2 is transmitted in the n +1 th half slot, HARQ-ACK generated by PDSCH-1 is transmitted in PUCCH-1 in n +6(k1 is 6) half slot, and HARQ-ACK generated by PDSCH-2 is transmitted in PUCCH-2 in n +8(k1 is 7) half slot, and then, when step S202 is executed, the method specifically includes:

step S2021: and determining the reference point with the PDSCH and HARQ feedback timing value equal to zero according to the overlapping condition of the time unit of the PDSCH and the time unit of the PUCCH for transmitting the HARQ-ACK.

Step S2022: and transmitting the HARQ-ACK information according to the reference point and the corresponding HARQ timing relation.

Wherein, the step S2021 includes any one of the following cases:

(1) when the time unit of the PDSCH is less than or equal to the time unit of the PUCCH for transmitting the HARQ-ACK, and more than one time unit of the PDSCH for transmitting the HARQ-ACK is completely overlapped with the time unit of one PUCCH for transmitting the HARQ-ACK, determining the time unit of the PUCCH for transmitting the HARQ-ACK as a reference point with the PDSCH and HARQ feedback timing value equal to zero;

specifically, in combination with step S2022, when the time unit (e.g., the slot length or a part of the slot length (e.g., half slot length)) in which the PDSCH is transmitted is less than or equal to the time unit (e.g., half slot length) in which the PUCCH in which the HARQ-ACK generated by the PDSCH is transmitted and the time units in which the multiple PDSCHs are transmitted completely overlap with the time unit in which the PUCCH in which the HARQ-ACK generated by the PDSCH is transmitted, as shown in fig. 7, assuming that the PDSCH in which the HARQ-ACK is generated or the PDCCH indicating SPS release is transmitted in time unit m and two time units m completely overlap with time unit n in which the HARQ-ACK is transmitted, the PDSCH or the HARQ-ACK indicating the SPS release is transmitted in time unit n + k 1.

(2) When the time unit of transmitting the PDSCH is larger than the time unit of transmitting the PUCCH of the HARQ-ACK, and the time unit of more than one PUCCH transmitting the HARQ-ACK is completely overlapped with the time unit of one PDSCH, determining one of the overlapped time units of more than one PUCCH transmitting the HARQ-ACK as a reference point with the PDSCH and HARQ feedback timing value equal to zero;

specifically, in connection with step S2022, when the time unit (for example, the slot length or a part of the slot length (for example, half the slot length)) in which the PDSCH is transmitted is greater than the time unit (for example, half the slot length) in which the PUCCH in which the HARQ-ACK generated by the PDSCH is transmitted, and the time unit in which the PDSCH is transmitted completely overlaps with the time units in which the PUCCHs in which the HARQ-ACKs generated by a plurality of PDSCHs are transmitted, one time unit in the time units in which the PUCCHs generated by a plurality of PDSCHs are transmitted, which overlaps with the time unit in which the PDSCH is transmitted, is selected as a reference point where k1 is equal to 0.

In the embodiment of the present application, a time unit may be preset as a reference point where the HARQ timing relationship k1 is equal to zero; for example, the first time unit is selected as the reference point for k1 equal to 0, or the second time unit is selected as the reference point for k1 equal to 0, or the last time unit is selected as the reference point for k1 equal to 0 by the protocol.

And a reference point with the PDSCH and HARQ feedback timing values equal to zero can be selected as a time unit according to the service requirement. For example, it is determined according to traffic demand that the last time unit is selected as a reference point where k1 equals 0, or that time units other than the last time unit are selected as reference points where k1 equals 0.

In practical application, if the service is an enhanced Mobile Broadband (eMBB) service, the last time unit in the overlapped HARQ-ACK transmission may be selected as a reference point where the PDSCH and HARQ feedback timing values are equal to zero, because the delay requirement is not very high for the eMBB service, and the last time unit may be selected as a reference point where k1 is equal to 0.

If the UR LL C service is low latency and high reliability, one of the time units except the last time unit in the overlapped transmission HARQ-ACKs may be selected as a reference point where the PDSCH and the HARQ feedback timing value are equal to zero, because for the UR LL C service, due to high latency requirements, selecting the last time unit as the reference point where k1 is equal to 0 may not satisfy the latency requirements, for example, as shown in fig. 8, assuming that the PDSCH generating the HARQ-ACK or the PDCCH indicating the SPS release is transmitted in time unit m, time units p, p +1, p +2 and p +3 where the HARQ-ACK is transmitted in time unit m and 4 time units p, p +1, p +2 and p +3, if the last time unit p +3 is the reference point where k1 is equal to 0 and all values of k1 are greater than or equal to 0, therefore, only the HARQ-ACK generated by the PDSCH transmitted in time unit m may be transmitted in time units p +3 and p +3, and p +2 may be configured as the reference point where p +2 is equal to p +3, p +2 may be configured as the reference point of the HARQ signaling protocol, and may be determined by configuring the reference point of the time unit p 1 or p + 3.

Alternatively, for UR LL C traffic, the last time unit in the overlapped HARQ-ACK transmission may be selected as the reference point where the PDSCH and HARQ feedback timing values are equal to zero, and the value of the HARQ timing relationship is determined to be an arbitrary integer, that is, the last time unit p +3 is still selected as the reference point where k1 is equal to 0, but the value of k1 may have a negative value, for example, k1 is-1, so that when k1 is equal to-1, HARQ-ACK is transmitted in time unit p + 2.

In practical applications, the service requirement is determined by at least one of: scheduling a scrambled radio network temporary identifier RNTI of a physical downlink control channel PDCCH of the PDSCH; the downlink control information DCI of the PDCCH, that is, which traffic is may be determined by the scrambled RNTI of the PDCCH scheduling the PDSCH or by information such as the DCI format of the PDCCH, that is, whether the last time unit p +3 is determined as a reference point where k1 is equal to 0 or the time units p, p +1, p +2 are determined as a reference point where k1 is equal to 0 by the scrambled RNTI of the PDCCH scheduling the PDSCH or by the DCI format of the PDCCH, for example, when the scrambled RNTI of the PDCCH scheduling the PDSCH is RNTI-1, the last time unit p +3 is determined as a reference point where k1 is equal to 0, and when the scrambled RNTI of the PDCCH scheduling the PDSCH is RNTI-2, the last time unit p +1 is determined as a reference point where k1 is equal to 0.

In another embodiment of the present application, when the time unit in which the PDSCH is transmitted and the time unit in which the PUCCH in which the HARQ-ACK is generated is located are all slot units, if the slot length of the PDSCH is greater than the slot length of the PUCCH in which the HARQ-ACK is generated, the slot in which the PDSCH is located may completely overlap with the slots of the plurality of PUCCHs in which the HARQ-ACK is generated, for example, as shown in fig. 9, the slot in which the PDSCH is located may completely overlap with the slots of the 4 PUCCHs in which the HARQ-ACK is generated. At this time, the method of the case (2) in the above step S2021 can be performed, and is not described herein again.

In another embodiment of the present application, when the time unit in which the PDSCH is transmitted and the time unit in which the PUCCH in which the HARQ-ACK is generated is located is all slot units, if the slot length of the PDSCH is less than or equal to the slot length of the PUCCH in which the HARQ-ACK is generated, one slot in which the PUCCH in which the HARQ-ACK is generated is located may completely overlap the slots in which the PDSCHs are located, for example, as shown in fig. 10, at this time, the method in the case (1) of the above step S2021 may be referred to, and details are not repeated here.

Further, step S2021 further includes any of the following cases:

(3) when the time unit of transmitting the PDSCH is not completely overlapped with the time unit of transmitting the PUCCH of the HARQ-ACK, determining one time unit of more than one time units of transmitting the PUCCH of the HARQ-ACK, which are overlapped with any time unit of transmitting the PDSCH, as a reference point with the PDSCH and HARQ feedback timing value equal to zero;

wherein, the time unit of the more than one PUCCH for transmitting HARQ-ACK can be completely overlapped or partially overlapped with the time unit of any PDSCH for transmitting.

In practical application, when at least one of the time unit in which the PDSCH is transmitted and the time unit in which the PUCCH for transmitting the HARQ-ACK generated by the PDSCH is transmitted is not in slot unit, regardless of whether the slot length of the PDSCH is greater or smaller than the slot length of the PUCCH transmitting the HARQ-ACK generated by the PDSCH, there may occur a case where one time unit in which the PDSCH is located may not completely overlap with the time units of a plurality of PUCCHs transmitting the HARQ-ACK generated by the PDSCH, for example, taking the case that the slot length of the PDSCH is smaller than the slot length of the PUCCH for transmitting HARQ-ACK generated by the PDSCH, as shown in fig. 11, when the subcarrier spaces of the PDSCH and the PUCCH are the same, the time unit of the PDSCH is 2 OFDM symbols, the time unit of the PUCCH is 7 OFDM symbols, and one time unit 3 where the PDSCH is located is not completely overlapped with the time unit 0 of the PUCCH for transmitting the HARQ-ACK generated by the PDSCH and the time unit 1 of the PUCCH for transmitting the HARQ-ACK generated by the PDSCH.

In the embodiment of the present application, in conjunction with step S2022, regardless of whether the time unit in which the PDSCH is transmitted and the time unit in which the PUCCH for HARQ-ACK generated by the PDSCH is transmitted are the same, and regardless of whether the subcarrier spatial configuration for the PDSCH is transmitted and the subcarrier spatial configuration for the PUCCH for HARQ-ACK generated by the PDSCH are the same, one time unit is selected from among the time units in which the PUCCHs for HARQ-ACK generated by the multiple PDSCHs are transmitted, which overlap the time unit in which the PDSCH is transmitted (the overlap includes full overlap and partial overlap), and is used as a reference point where k1 is equal to 0.

In practical application, in the case of the eMBB service, the last time unit in the overlapped HARQ-ACK transmission may be selected as a reference point where the PDSCH and HARQ feedback timing values are equal to zero, because the latency requirement is not very high for the eMBB service, the last time unit may be selected as a reference point where k1 is equal to 0.

If UR LL C traffic is used, one of the overlapping transmitted HARQ-ACKs except the last time unit may be selected as a reference point where the PDSCH and HARQ feedback timing values are equal to zero, because for UR LL C traffic, due to high latency requirements, selecting the last time unit as the reference point where k1 is equal to 0 may not satisfy the latency requirements, for example, assuming that the PDSCH generating the HARQ-ACK or the PDCCH indicating SPS release is transmitted in time unit m, time units m and 4 time units p, p +1, p +2 and p +3 in which the HARQ-ACK is transmitted, if the last time unit p +3 is the reference point where k1 is equal to 0 and all values of k1 are greater than or equal to 0, therefore, the HARQ-ACK generated by the PDSCH transmitted in time unit m can only be transmitted in time after p +3 and p +3, and when the PDSCH is transmitted in the front OFDM symbol in time unit m, it is required that the PDSCH-transmitted in time unit p +1 or time unit p +2, so that which p +2 is transmitted is equal to p +2, which p +2 is the reference point of the HARQ feedback timing requirements may be configured as a reference point of the preset HARQ signaling protocol of which p 1 or the reference point.

The above three cases are determined as the reference point where k1 is equal to 0 in the overlapping condition of the time unit where the PDSCH is transmitted and the time unit where the PUCCH is transmitted, and in some cases, the PDSCH is transmitted in a part of the time unit where the PDSCH is transmitted, for example, the time unit where the PDSCH is transmitted is a slot, one slot includes 14 OFDM symbols, and the PDSCH is transmitted in the second OFDM symbol and the third OFDM symbol of the 14 symbols in the slot, which may cause an excessive delay if the reference point where k1 is equal to 0 is determined as the overlapping condition of the time unit where the PDSCH is transmitted and the time unit where the PUCCH is transmitted.

In the embodiment of the application, a reference point with a PDSCH and HARQ feedback timing value equal to zero is determined according to the overlapping condition of an OFDM symbol in a time slot for actually transmitting the PDSCH and a time unit where a PUCCH for transmitting HARQ-ACK is located, and then HARQ-ACK information is transmitted according to the reference point and the corresponding HARQ timing relation.

Specifically, determining the reference point as k1 being equal to 0 in the overlapping case of the OFDM symbol actually transmitting the PDSCH and the time unit in which the PUCCH transmitting the HARQ-ACK includes any of the following cases:

(1) determining a reference point with k1 equal to 0 according to the overlapping condition of the last OFDM symbol for actually transmitting the PDSCH and the time unit of the PUCCH for transmitting the HARQ-ACK, namely determining the time unit of the PUCCH for transmitting the HARQ-ACK as the reference point with the PDSCH and HARQ feedback timing value equal to zero when the last OFDM symbol for actually transmitting the PDSCH is only overlapped with the time unit of the PUCCH for transmitting the HARQ-ACK;

as shown in fig. 12, when the last OFDM symbol actually transmitting PDSCH overlaps with only the time unit where one PUCCH transmitting HARQ-ACK is located, the time unit where PUCCH transmitting HARQ-ACK is located is taken as a reference point where k1 is equal to 0.

(2) When the last OFDM symbol actually transmitting the PDSCH is overlapped with the time unit of more than one PUCCH transmitting the HARQ-ACK, the time unit of the PUCCH transmitting the HARQ-ACK is determined as a reference point with the PDSCH and HARQ feedback timing value equal to zero.

As shown in fig. 13, when the last OFDM symbol actually transmitting the PDSCH overlaps with the time unit where more than one PUCCH is transmitting the HARQ-ACK, the time unit where the PUCCH is transmitting the HARQ-ACK is taken as the reference point where k1 is equal to 0, because the UE only transmits the HARQ-ACK in the time unit where the PUCCH is transmitting the HARQ-ACK and the time unit after the PUCCH, the UE does not transmit the HARQ-ACK generated by the PDSCH in the time unit where the PUCCH is transmitting the HARQ-ACK before the PDSCH is not finished.

As shown in fig. 13, the last OFDM symbol for transmitting PDSCH partially overlaps with the time unit n-1 of PUCCH for transmitting HARQ-ACK and the time unit n of PUCCH for transmitting HARQ-ACK, but when the time unit n-1 of PUCCH for transmitting HARQ-ACK ends, the last OFDM symbol for transmitting PDSCH has not yet ended, so HARQ-ACK for this PDSCH cannot be transmitted in the time unit n-1, and if the time unit n-1 is taken as the reference point that k1 equals 0, HARQ-ACK will not be transmitted in the time unit that k1 equals 0, which is equivalent to wasting the timing relation indication information that k1 equals 0, and the time unit n is taken as the reference point that k1 equals 0, HARQ-ACK for this PDSCH may be transmitted in the time unit n.

In the embodiment of the present application, when a PUCCH for CSI (Channel State Information, transport Channel State Information) overlaps with at least two PUCCHs for HARQ-ACK transmission in one slot, the CSI and the HARQ-ACK may be multiplexed in any one of the following manners:

(1) multiplexing CSI in the last PUCCH in which HARQ-ACK is transmitted;

taking two PUCCHs for transmitting HARQ-ACK in one slot as an example, when the PUCCH for transmitting CSI is overlapped with the two PUCCHs for transmitting HARQ-ACK, CSI is multiplexed in the last PUCCH for transmitting HARQ-ACK, so that the timing relationship of HARQ-ACK can be satisfied by comparing, as shown in FIG. 14, PUCCH-1 and PUCCH-2 for transmitting HARQ-ACK are partially overlapped with PUCCH-CSI for transmitting CSI, and CSI is multiplexed in the following PUCCH-2.

(2) And multiplexing the CSI in the PUCCH of the first transmission HARQ-ACK meeting the time delay requirement.

Taking two PUCCHs for transmitting HARQ-ACK in one slot as an example, when a PUCCH for transmitting CSI is overlapped with two PUCCHs for transmitting HARQ-ACK, the CSI is multiplexed in a first PUCCH for transmitting HARQ-ACK which meets the delay requirement, so that the timing relation of the HARQ-ACK can be met, and the CSI can be transmitted as soon as possible, as shown in FIG. 15, PUCCH-1 and PUCCH-2 for transmitting the HARQ-ACK are partially overlapped with the PUCCH-CSI for transmitting the CSI, and when a time interval L between the PUCCH-1 for transmitting the HARQ-ACK and a reference resource for the CSI is greater than or equal to the delay processing requirement T for the CSI, the CSI is multiplexed in the first PUCCH-1 for transmitting the HARQ-ACK which meets the delay requirement.

In the embodiment of the present application, when the number of HARQ-ACK bits is determined by a semi-static (semi-static) higher layer signaling configuration, the PDCCH for scheduling the PDSCH further includes an indication information field of the number of HARQ-ACK bits. That is, in the embodiment of the present application, an HARQ-ACK bit number indication information field may be added to a PDCCH for scheduling a PDSCH to indicate the number of bits of HARQ-ACK.

Specifically, the number of bits indicating the HARQ-ACK is the number of HARQ-ACK bits generated by one PDSCH; or

Illustratively, the HARQ-ACK bit number indication information field is 1 bit: when the bit value is '0', the bit number of the HARQ-ACK is the HARQ-ACK bit number generated by one PDSCH; and when the bit value is "1", the bit value indicates the number of bits of the HARQ-ACK, which can be determined according to the set of all downlink time slots that may need to feed back the HARQ-ACK in the uplink subframe n.

For example, the UE configures 4 serving cells, each serving cell may need to include 4 elements in a set of downlink timeslots for feeding back HARQ-ACK in an uplink timeslot n, that is, each serving cell has HARQ-ACK feedback information of 4 downlink timeslots to be transmitted in one uplink timeslot n, that is, all sets of downlink timeslots for feeding back HARQ-ACK in an uplink subframe n include 16 downlink timeslots of 4 serving cells. Thus, the total number of bits of HARQ-ACK transmitted in PUCCH in one uplink slot is 4 × 4 — 16 bits.

When the UE determines that the base station only transmits the PDSCH or the PDCCH indicating SPS release in one downlink time slot of one serving cell (for example, the UE only receives one PDCCH for scheduling the PDSCH, and the HARQ-ACK bit number indication information value in the PDCCH is equal to 0) in the 4 serving cells, that is, when only one downlink time slot of one serving cell has HARQ-ACK feedback information transmission, the number of bits of the HARQ-ACK feedback information is q (q may be 1 or 2, and when it is determined according to the transmission mode of the serving cell, for example, the transmission mode of the serving cell supports one transport block transmission, q is 1).

When the UE is in the 4 serving cells, the UE knows that the base station sends the PDSCH or the PDCCH indicating SPS release in at least two downlink time slots of one serving cell or multiple serving cells (for example, the UE receives the PDCCH for scheduling the PDSCH, and the HARQ-ACK bit number indication information value in the PDCCH is equal to 1, or the UE receives the PDCCH for scheduling the PDSCH), that is, when there is HARQ-ACK feedback information transmission in at least two downlink time slots, the bit number of the HARQ-ACK feedback information is the total HARQ-ACK bit number corresponding to all downlink time slots in the set.

and transmitting the HARQ-ACK information according to the reference point and the corresponding HARQ timing relation.

In an alternative implementation, the transmission module 1602 is specifically configured to any of the following situations:

In an alternative implementation, the transmission module 1602 is specifically configured to any one of:
