technical field

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

Background technique

The Long Term Evolution (LTE, Long Term Evolution) technology supports two duplex modes: Frequency Division Duplex (FDD, Frequency Division Duplex) and Time Division Duplex (TDD, Time Division Duplex). FIG. 1 is a schematic diagram of a frame structure of a TDD system of LTE. The length of each radio frame is 10 milliseconds (ms), and it is divided into two half-frames of length 5ms. Every two consecutive time slots constitute a subframe, and three special domains constitute a special subframe. The three special domains are downlink pilot time slot (DwPTS, Downlinkpilot time slot), guard interval (GP, Guard period) and Uplink pilot time slot (UpPTS, Uplink pilottime slot).

The transmission in the TDD system includes: the transmission from the base station to the user equipment (UE, User Equipment) (called downlink) and the transmission from the UE to the base station (called uplink). Based on the frame structure shown in Figure 1, the uplink and downlink share 10 subframes every 10ms, and each subframe is either configured for uplink or downlink. The subframe configured for uplink is called uplink subframe, and the subframe configured for downlink is called uplink subframe. The subframes are called downlink subframes. Seven uplink and downlink configurations are supported in the TDD system, as shown in Table 1, D represents a downlink subframe, U represents an uplink subframe, and S represents the above-mentioned special subframe including three 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. The subcarrier space is different, and the length of the time slot is also different. The subcarrier space configuration and time slot The corresponding relationship of length is shown in Table 2.

The HARQ-ACK (Hybrid Automatic Retransmission Request Acknowledgement, Hybrid Automatic Retransmission Request Acknowledgement) information of PDSCH (Physical Downlink Shared Channel) can be in PUSCH (Physical Uplink Shared Channel, Physical Uplink Shared Channel) or PUCCH (Physical Uplink Shared Channel) Control Channel, physical uplink control channel) transmission. In the PUCCH subframe, one PUCCH resource is allocated for each PDSCH of each downlink subframe to feed back the HARQ-ACK feedback information.

For the timing relationship between PDSCH and PUCCH, it is assumed that the UE feeds back HARQ-ACK feedback information in the PUCCH of uplink subframe n, then the PUCCH indicates the PDSCH in downlink subframes n-k or indicates the PDCCH released by Semi Persistent Scheduling (SPS, Semi Persistent Scheduling). (Physical Downlink Control Channel, Physical Downlink Control Channel)/ePDCCH (Enhanced PDCCH, Enhanced Physical Downlink Control Channel) The HARQ-ACK feedback information generated, the timing relationship k between PDSCH and the PUCCH that transmits the HARQ-ACK generated by PDSCH is called HARQ (Hybrid Automatic Retransmission Request, Hybrid Automatic Retransmission Request) timing relationship.

As mentioned above, due to the different subcarrier spaces, the lengths of the time slots are also different. If this HARQ timing relationship is still directly used to transmit HARQ-ACK information, the transmission effect will be affected and some resources will be wasted.

In order to make the objectives, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

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

Step S201: The terminal determines the time unit where the PUCCH for transmitting HARQ-ACK is located according to the time slot length of the time slot where the PUCCH for transmitting HARQ-ACK is located and the number of PUCCHs in the time slot.

Step S202: The terminal transmits the HARQ-ACK information based on the determined time unit where the PUCCH for transmitting the HARQ-ACK is located and the corresponding HARQ timing relationship.

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

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

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

(2) When more than one PUCCH is used to transmit HARQ-ACK in one time slot, a part of one time slot is determined as the time unit where the PUCCH for transmitting HARQ-ACK is located.

Each time slot may have multiple PUCCHs that transmit the dynamically scheduled PDSCH, SPS PDSCH or HARQ-ACK indicating the PDCCH released by the SPS. For example, as shown in Figure 3, in time slot n, there are two HARQ-ACK transmissions. PUCCH, respectively PUCCH-1 and PUCCH-2.

When there is more than one PUCCH in a time slot for transmitting HARQ-ACK, the HARQ timing relationship k1 cannot only use the length of the time slot of the PUCCH transmitting HARQ-ACK as the time unit, because it cannot distinguish which PUCCH in the time slot is. To transmit HARQ-ACK, a method can indicate the timing relationship of HARQ in this case, that is, a part of a time slot is determined as the time unit in which the PUCCH of the HARQ-ACK is transmitted.

Specifically, the HARQ timing relationship k1 takes a part of one slot as a time unit. For example, as shown in Figure 4, there are two PUCCHs in one time slot to transmit HARQ-ACK, then k1 can be half a time slot as the time unit, PDSCH-1 is transmitted in the nth half time slot, PDSCH-2 is transmitted in the nth time 1 half timeslot transmission, HARQ-ACK generated by PDSCH-1 is transmitted in PUCCH-1 within n+6 (k1 is 6) half timeslots, and HARQ-ACK generated by PDSCH-2 is transmitted in n+8 (k1 is 6). 7) PUCCH-2 transmission in half a slot.

(3) When there is more than one PUCCH in a time slot for transmitting HARQ-ACK, determine the length of one time slot as the time unit where the PUCCH for transmitting HARQ-ACK is located, and receive indication information. The indication information is used to indicate that according to the The HARQ-ACK is transmitted on a specific PUCCH in the time slot of which the HARQ-ACK is transmitted with the length of one time slot being determined by the time unit.

Each time slot may have multiple PUCCHs that transmit the dynamically scheduled PDSCH, SPS PDSCH or HARQ-ACK indicating the PDCCH released by the SPS. For example, as shown in Figure 3, in time slot n, there are two HARQ-ACK transmissions. PUCCH, respectively PUCCH-1 and PUCCH-2.

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

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

Since the subcarrier space configuration may be different in different serving cells and at different times in the same serving cell, the length of the time slot may be different. In addition, the subcarrier space configuration of the PUCCH for transmitting HARQ-ACK and the subcarrier space configuration for generating HARQ-ACK The subcarrier space configuration of the PDSCH may also be different, so the time slot length of the PUCCH for transmitting HARQ-ACK and the time slot length of the PDSCH for generating HARQ-ACK may also be different, as shown in FIG. 6 .

In the embodiment of the present application, after a part of a time slot is determined as the time unit where the PUCCH for transmitting HARQ-ACK is located, that is, when the HARQ timing relationship in step S201 is indicated by the above situation (2), the HARQ timing relationship k1 is determined by one time slot part of the time unit. For example, as shown in Figure 4, there are two PUCCHs in one time slot to transmit HARQ-ACK, then k1 can be half a time slot as the time unit, PDSCH-1 is transmitted in the nth half time slot, PDSCH-2 is transmitted in the nth time 1 half timeslot transmission, HARQ-ACK generated by PDSCH-1 is transmitted in PUCCH-1 within n+6 (k1 is 6) half timeslots, and HARQ-ACK generated by PDSCH-2 is transmitted in n+8 (k1 is 6). 7) PUCCH-2 transmission in half time slot, then, when step S202 is executed, it specifically includes:

Step S2021: According to the overlapping situation of the time unit where the PDSCH is located and the time unit where the PUCCH transmitting HARQ-ACK is located, determine the reference point where the PDSCH and HARQ feedback timing values are equal to zero.

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

Wherein, step S2021 includes any of the following situations:

(1) When the time unit where the PDSCH is located is less than or equal to the time unit where the PUCCH that transmits HARQ-ACK is located, and more than one time unit where the PDSCH is transmitted completely overlaps the time unit where the PUCCH that transmits HARQ-ACK is located, the A time unit where a PUCCH for transmitting HARQ-ACK is located is determined as a reference point where the PDSCH and HARQ feedback timing values are equal to zero;

Specifically, in conjunction with step S2022, when the time unit in which the PDSCH is transmitted (for example, the time slot length or a part of the time slot length (for example, half the time slot length)) is less than or equal to the time in which the PUCCH of the HARQ-ACK generated by the PDSCH is transmitted unit (for example, half a time slot length), and the time unit in which multiple PDSCHs are transmitted and the time unit in which the PUCCH of HARQ-ACK generated by transmitting PDSCH is completely overlapped. As shown in Figure 7, it is assumed that the PDSCH of HARQ-ACK is generated or The PDCCH indicating the SPS release is transmitted within the time unit m, and the two time units m completely overlap with the time unit n where the HARQ-ACK is transmitted, then the PDSCH or the HARQ-ACK of the PDCCH indicating the SPS release is transmitted within the time unit n+k1 .

(2) When the time unit where the PDSCH is transmitted is larger than the time unit where the PUCCH where HARQ-ACK is transmitted, and the time unit where more than one PUCCH where HARQ-ACK is transmitted completely overlaps the time unit where one PDSCH is transmitted, the overlap will be One of the time units in the time unit where more than one PUCCH for transmitting HARQ-ACK is located is determined as a reference point where the PDSCH and HARQ feedback timing values are equal to zero;

Specifically, in conjunction with step S2022, when the time unit in which the PDSCH is transmitted (for example, the time slot length or a part of the time slot length (for example, half the time slot length)) is greater than the time unit in which the PUCCH of the HARQ-ACK generated by the PDSCH transmission is located (for example, half the time slot length), and the time unit where the PDSCH is transmitted completely overlaps the time unit where the PUCCH of the HARQ-ACK generated by multiple transmission PDSCHs is located, select multiple transmission PDSCHs that overlap the time unit where the PDSCH is transmitted. One time unit in the time unit where the PUCCH of the generated HARQ-ACK is located is used as a reference point where k1 is equal to 0.

In this 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 where k1 is equal to 0 through a protocol, or the second time unit is selected as the reference point where k1 is equal to 0 0 reference point, or choose the last time unit as the reference point where k1 is equal to 0.

A reference point whose time unit is the PDSCH and HARQ feedback timing values equal to zero may also be selected according to service requirements. For example, according to business requirements, it is determined to select the last time unit as the reference point where k1 is equal to 0, or select time units other than the last time unit as the reference point where k1 equals 0.

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

If it is a low-latency and high-reliability URLLC service, one of the time units except the last time unit in the overlapping transmission HARQ-ACK can be selected as the reference point where the PDSCH and HARQ feedback timing values are equal to zero, because for the URLLC service, due to The delay requirement is high, and selecting the last time unit as the reference point where k1 is equal to 0 may not meet the delay requirement. For example, as shown in Figure 8, it is assumed that the PDSCH generating HARQ-ACK or the PDCCH indicating SPS release is transmitted within the time unit m , the time unit m and the time units p, p+1, p+2 and p+3 where the 4 HARQ-ACKs are transmitted, if the last time unit p+3 is used as the reference point where k1 is equal to 0, and all the values of k1 are greater than or equal to 0. Therefore, the HARQ-ACK generated by the PDSCH transmitted in the time unit m can only be transmitted in the time after p+3 and p+3, and when the PDSCH is transmitted in the first OFDM symbol in the time unit m. , the HARQ-ACK of the PDSCH needs to be transmitted on the time unit p+1 or time unit p+2, so as to meet the delay requirement, the time unit p, p+1, p+2 can be used as the reference point where k1 is equal to 0 , which of the time units can be used as the reference point where k1 is equal to 0 can be determined through signaling configuration or protocol preset.

Alternatively, if it is a URLLC service, the last time unit in the overlapping transmission HARQ-ACK can also be selected as a 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 can have a negative value, such as k1=-1, so that when k1 is equal to -1, the HARQ-ACK is in the time unit p +2 for transmission.

In practical applications, the service requirements are determined by at least one of the following: the scrambled wireless network temporary identifier RNTI of the physical downlink control channel PDCCH of the scheduling PDSCH; the downlink control information DCI of the PDCCH, that is, for which service can be scheduled by the PDCCH of the PDSCH The scrambled RNTI is determined by the information such as the DCI format of the PDCCH, that is, the scrambled RNTI of the PDCCH of the scheduling PDSCH or the DCI format of the PDCCH to determine the last time unit p+3 as the reference point where k1 is equal to 0, or Determine the time unit p, p+1, p+2 as the reference point where k1 is equal to 0, for example, when the scrambled RNTI of the PDCCH scheduling PDSCH is RNTI-1, the last time unit p+3 is used as the k1 equal to 0. The reference point, when the scrambled RNTI of the PDCCH that schedules the PDSCH is RNTI-2, the last time unit p+1 is used as the 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 of the HARQ-ACK generated by the PDSCH is transmitted is in a time slot, if the time slot of the PDSCH is longer than the HARQ generated by the PDSCH transmission - The length of the time slot of the PUCCH of the ACK, then a time slot where the PDSCH is located will completely overlap with the time slot of the PUCCH of the HARQ-ACK generated by multiple transmission PDSCHs. The time slots of the PUCCH for transmitting HARQ-ACK generated by PDSCH completely overlap. In this case, the method in the situation (2) of the above step S2021 may be referred to for execution, and details are not described herein again.

In another embodiment of the present application, when the time unit where the PDSCH is transmitted and the time unit where the PUCCH of the HARQ-ACK generated by the PDSCH is transmitted is in the unit of time slot, if the length of the time slot of the PDSCH is less than or equal to the time unit generated by the transmission of the PDSCH The length of the time slot of the PUCCH of the HARQ-ACK, then the time slot where the PUCCH of the HARQ-ACK generated by the transmission of PDSCH is located will completely overlap with the time slots where multiple PDSCHs are located, for example, as shown in Figure 10, at this time, you can refer to the above steps. The method execution of the situation (1) of S2021 is not repeated here.

Further, step S2021 also includes any of the following situations:

(3) When the time unit where the PDSCH is transmitted does not completely overlap with the time unit where the PUCCH where the HARQ-ACK is transmitted, more than one time unit where the PUCCH where the HARQ-ACK is transmitted will overlap with any time unit where the PDSCH is transmitted. One of the time units is determined as a reference point where the PDSCH and HARQ feedback timing values are equal to zero;

Wherein, the time unit in which the more than one PUCCH for transmitting HARQ-ACK is located may completely overlap or partially overlap with the time unit in which any one of the PDSCH transmissions is located.

In practical applications, when at least one of the time unit in which the PDSCH is transmitted and the time unit in which the HARQ-ACK generated by the PDSCH is transmitted is not in a time slot, regardless of whether the length of the time slot of the PDSCH is greater than or smaller than the HARQ generated by the transmission of the PDSCH. - The length of the time slot of the PUCCH of the ACK may occur in that a time unit where the PDSCH is located will not completely overlap with the time unit of the PUCCH of the HARQ-ACK generated by multiple PDSCH transmissions. For example, the time slot length of the PDSCH is smaller than the transmission PDSCH Take the time slot length of the generated HARQ-ACK PUCCH as an example. As shown in Figure 11, when the subcarrier spaces of PDSCH and PUCCH are the same, the time unit of PDSCH is 2 OFDM symbols, and the time unit of PUCCH is 7 OFDM symbols. A time unit 3 where the PDSCH is located does not completely overlap 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 this embodiment of the present application, in conjunction with step S2022, regardless of whether the time unit in which PDSCH is transmitted and the time unit in which the PUCCH of HARQ-ACK generated by PDSCH transmission is located are the same, and whether the subcarrier space configuration for PDSCH transmission and the PUCCH for HARQ-ACK transmission are the same Whether the subcarrier space configuration is the same, select a time unit as k1 in the time unit where the HARQ-ACK generated by multiple PDSCH transmissions that overlap with the time unit where PDSCH is transmitted (this overlap includes complete overlap and partial overlap) A reference point equal to 0.

In this 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 where k1 is equal to 0 through a protocol, or the second time unit is selected as the reference point where k1 is equal to 0 0 reference point, or choose the last time unit as the reference point where k1 is equal to 0.

A reference point whose time unit is the PDSCH and HARQ feedback timing values equal to zero may also be selected according to service requirements. For example, according to business requirements, it is determined to select the last time unit as the reference point where k1 is equal to 0, or select time units other than the last time unit as the reference point where k1 equals 0.

In practical applications, if it is an eMBB service, the last time unit in the overlapping transmission HARQ-ACK can be selected as the reference point where the PDSCH and HARQ feedback timing values are equal to zero. A time unit is used as the reference point where k1 is equal to 0.

If it is a URLLC service, one of the time units other than the last time unit in the overlapping transmission HARQ-ACK can be selected as the reference point where the PDSCH and HARQ feedback timing values are equal to zero, because for the URLLC service, due to the high delay requirement, Selecting the last time unit as the reference point with k1 equal to 0 may not meet the delay requirement. For example, it is assumed that the PDSCH generating HARQ-ACK or the PDCCH indicating SPS release is transmitted within the time unit m, and the time unit m and 4 transmission HARQ-ACKs In the time units p, p+1, p+2 and p+3, if the last time unit p+3 is used as the reference point for k1 equal to 0, and all values of k1 are greater than or equal to 0, therefore, in the time unit m The HARQ-ACK generated by the transmitted PDSCH can only be transmitted in the time after p+3 and p+3, and when the PDSCH is transmitted in the first OFDM symbol within the time unit m, the HARQ-ACK of the PDSCH is required in the time unit. p+1 or time unit p+2, so as to meet the delay requirement, the time unit p, p+1, p+2 can be used as the reference point where k1 is equal to 0, which can be determined by signaling configuration or protocol preset Which time unit is used as the reference point for which k1 is equal to 0.

Alternatively, if it is a URLLC service, the last time unit in the overlapping transmission HARQ-ACK can also be selected as a 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 can have a negative value, such as k1=-1, so that when k1 is equal to -1, the HARQ-ACK is in the time unit p +2 for transmission.

In practical applications, the service requirements are determined by at least one of the following: the scrambled wireless network temporary identifier RNTI of the physical downlink control channel PDCCH of the scheduling PDSCH; the downlink control information DCI of the PDCCH, that is, for which service can be scheduled by the PDCCH of the PDSCH The scrambled RNTI is determined by the information such as the DCI format of the PDCCH, that is, the scrambled RNTI of the PDCCH of the scheduling PDSCH or the DCI format of the PDCCH to determine the last time unit p+3 as the reference point where k1 is equal to 0, or Determine the time unit p, p+1, p+2 as the reference point where k1 is equal to 0, for example, when the scrambled RNTI of the PDCCH scheduling PDSCH is RNTI-1, the last time unit p+3 is used as the k1 equal to 0. The reference point, when the scrambled RNTI of the PDCCH that schedules the PDSCH is RNTI-2, the last time unit p+1 is used as the reference point where k1 is equal to 0.

In the above three cases, the overlap of the time unit where the PDSCH is transmitted and the time unit where the PUCCH where the HARQ-ACK is transmitted is determined as the reference point where k1 is equal to 0. In some cases, the PDSCH is part of the time unit where the PDSCH is transmitted. For example, the time unit in which PDSCH is transmitted is a time slot, and a time slot contains 14 OFDM symbols. PDSCH is transmitted in the second and third OFDM symbols of the 14 symbols in the time slot. If Determining the overlap of the time unit where the PDSCH is transmitted and the time unit where the PUCCH where the HARQ-ACK is transmitted is determined as the reference point where k1 is equal to 0 may cause excessive delay.

In the embodiment of the present application, according to the overlap between the OFDM symbol in the time slot in which the PDSCH is actually transmitted and the time unit in which the PUCCH in which the HARQ-ACK is transmitted is located, the reference point at which the PDSCH and HARQ feedback timing values are equal to zero is determined, and then according to the reference point and the corresponding HARQ timing relationship, transmit HARQ-ACK information.

Specifically, determining the reference point where k1 is equal to 0 is determined as the reference point where k1 is equal to 0 based on the overlap between the OFDM symbol that actually transmits the PDSCH and the time unit where the PUCCH that transmits the HARQ-ACK includes any of the following situations:

(1) Determine the reference point where k1 is equal to 0 based on the overlap between the last OFDM symbol of the actual PDSCH transmission and the time unit where the PUCCH of the HARQ-ACK transmission is located, that is, when the last OFDM symbol of the actual PDSCH transmission is only associated with one transmission HARQ - When the time units where the PUCCH of the ACK is located overlap, the time unit where the PUCCH where the HARQ-ACK is transmitted is determined as the reference point where the PDSCH and HARQ feedback timing values are equal to zero;

As shown in FIG. 12 , when the last OFDM symbol of the actual PDSCH transmission only overlaps with a time unit where the PUCCH that transmits HARQ-ACK is located, the time unit where the PUCCH that transmits HARQ-ACK is located is taken as the reference point where k1 is equal to 0.

(2) When the last OFDM symbol that actually transmits PDSCH overlaps with more than one time unit where the PUCCH that transmits HARQ-ACK is located, the time unit where the last PUCCH that transmits HARQ-ACK is located is determined as the PDSCH and HARQ feedback timing value A reference point equal to zero.

As shown in FIG. 13 , when the last OFDM symbol of the actual PDSCH transmission overlaps with more than one time unit of the PUCCH that transmits HARQ-ACK, the time unit of the last PUCCH that transmits HARQ-ACK is taken as k1 equal to 0. Reference point, because at this time, the UE will only transmit HARQ-ACK in the time unit where the last PUCCH that transmits HARQ-ACK is located and the time unit after that, and the UE will not transmit HARQ-ACK before the end of PDSCH. PUCCH where the HARQ-ACK is located The HARQ-ACK generated by the PDSCH is transmitted in the time unit.

As shown in Fig. 13, the last OFDM symbol in which PDSCH is transmitted overlaps with the time unit n-1 where the PUCCH where HARQ-ACK is transmitted and the time unit n where the PUCCH where HARQ-ACK is transmitted is partially overlapped. At the end of the time unit n-1, the last OFDM symbol for PDSCH transmission has not ended. Therefore, the HARQ-ACK of the PDSCH cannot be transmitted in the time unit n-1. If the time unit n-1 is regarded as k1 equal to 0 , the HARQ-ACK will not be transmitted in the time unit where k1 is equal to 0, which is equivalent to wasting the timing relationship indication information that k1 is equal to 0, and the time unit n is used as the reference point where k1 is equal to 0. The HARQ-ACK of the PDSCH ACK may be transmitted in time unit n.

In this embodiment of the present application, when the PUCCH of CSI (Channel State Information, transmission channel state information) overlaps with at least two PUCCHs that transmit HARQ-ACK in a time slot, CSI and HARQ-ACK can be multiplexed in any of the following ways. ACK:

(1) Multiplexing CSI in the last PUCCH for transmitting HARQ-ACK;

Taking two PUCCHs that transmit HARQ-ACK in a time slot as an example, when the PUCCH that transmits CSI overlaps with the two PUCCHs that transmit HARQ-ACK, the CSI is multiplexed in the last PUCCH that transmits HARQ-ACK, so that Comparing the timing relationship that can satisfy HARQ-ACK, as shown in Figure 14, PUCCH-1 and PUCCH-2 for transmitting HARQ-ACK partially overlap with PUCCH-CSI for transmitting CSI, and CSI is multiplexed in the following PUCCH-2.

(2) Multiplexing the CSI in the first PUCCH for transmitting HARQ-ACK that meets the delay requirement.

Taking two PUCCHs for transmitting HARQ-ACK in a time slot as an example, when the PUCCH for transmitting CSI overlaps with the two PUCCHs for transmitting HARQ-ACK, the CSI is multiplexed in the first transmission HARQ-ACK that meets the delay requirement. In the PUCCH of ACK, this comparison can satisfy the timing relationship of HARQ-ACK, and can transmit CSI as soon as possible. As shown in Figure 15, PUCCH-1 and PUCCH-2 for transmitting HARQ-ACK and PUCCH-CSI part for transmitting CSI Overlapping, when the time interval L between the PUCCH-1 for transmitting HARQ-ACK and the CSI reference resource is greater than or equal to the CSI delay processing requirement T, the CSI is multiplexed in the first transmission HARQ-ACK that meets the delay requirement within the PUCCH-1.

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

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

The number of bits indicating the HARQ-ACK is the number of HARQ-ACK bits determined according to the set of downlink time slots in which the HARQ-ACK is fed back in any uplink subframe.

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

For example, if the UE is configured with 4 serving cells, each serving cell may need to include 4 elements in the set of downlink time slots for HARQ-ACK feedback in uplink time slot n, that is, each serving cell has 4 downlink time slots The HARQ-ACK feedback information is transmitted in one uplink time slot n, that is, the set of all downlink time slots that need or may need to feed back HARQ-ACK in uplink subframe n includes 16 downlink time slots of 4 serving cells. In this way, the total number of bits of the HARQ-ACK transmitted on the PUCCH in one uplink time slot is 4*4=16 bits.

When the UE is in these 4 serving cells, the UE knows that the base station only sends PDSCH or PDCCH indicating SPS release in one downlink time slot of one serving cell (for example, the UE only receives one PDCCH scheduling PDSCH, and the PDCCH in the PDCCH The number of HARQ-ACK bits indicates that the information value is equal to 0), 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 can be 1 or 2, depending on The transmission mode of the serving cell is determined, for example, when the transmission mode of the serving cell supports transmission of one transport block, q is 1).

When the UE is in these 4 serving cells, the UE determines that the base station sends PDSCH or PDCCH indicating SPS release in at least two downlink time slots of one serving cell or multiple serving cells (for example, the UE receives a PDCCH scheduling PDSCH, And the number of HARQ-ACK bits in the PDCCH indicates that the information value is equal to 1, or the UE has received at least two PDCCHs that schedule PDSCH), that is, when there is HARQ-ACK feedback information transmission in at least two downlink time slots, the HARQ-ACK feedback The number of bits of information is the total number of bits of HARQ-ACK corresponding to all downlink time slots in the foregoing set.
