Description

HARQ-ACK information transmission method, device, terminal and network equipment

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a method, an apparatus, a terminal, and a network device for transmitting HARQ-ACK information.

Background

With the development of mobile communication service requirements, several organizations such as the international telecommunication union, telecommunication standards bureau, ITU, etc. have started to research New wireless communication systems (i.e. 5G NR, 5Generation New RAT, 5G New radio access technology) for future mobile communication systems. Various subcarrier spacing configurations are supported in the 5G NR, and specifically, the subcarrier spacing configurations may be 15kHz, 30kHz, 60kHz, 120kHz and 240kHz, where when the subcarrier spacing configuration is 60kHz, transmission using normal cyclic prefix CP (i.e., non-extended CP) and extended CP is supported, and when the other subcarrier spacing configurations are only supported, transmission using normal CP is supported.

Furthermore, flexible timing relationships are supported in the 5G NR. For a Physical Downlink Shared CHannel (PDSCH), a Physical Downlink Control CHannel (PDCCH) carrying scheduling information thereof indicates a scheduling timing relationship (K0) between the PDSCH and the PDCCH and a feedback timing relationship (HARQ-ACK timing, K1) between the PDSCH and its corresponding hybrid automatic repeat request acknowledgement HARQ-ACK. Specifically, a time domain resource allocation indication field in a Downlink Control Information (DCI) format used by the PDCCH indicates a time slot offset K0 between a time slot in which the PDSCH is located and a time slot in which the DCI is located; the PDSCH-to-HARQ-ACK feedback timing indication field in the DCI format indicates the number of slots K1 between the PDSCH end and the HARQ-ACK start, i.e., the PDSCH transmission at the end position at slot n performs HARQ-ACK transmission in slot n + K1, as shown in fig. 1 (ECP in the figure indicates extended CP, i.e., extended CP, and NCP indicates normal CP, i.e., normal CP). The full set of K1 is {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15}, and is typically configured for a maximum of 8 values for the terminal. The value of K1 is in units of slots, i.e., K1 ═ 1 indicates a 1 slot interval. K1-0 corresponds to the last PUCCH slot that overlaps with the received PDSCH or PDCCH indicating SPS (semi-persistent scheduling) PDSCH release.

Currently, in the NR communication system, the semi-static codebook scheme and the dynamic codebook scheme are used to support HARQ-ACK feedback.

When configured to use the semi-static HARQ-ACK codebook, the UE first determines that each carrier c corresponds to the same time according to the HARQ-ACK feedback timing (K1), the semi-static slot structure (if configured), and the PDSCH candidate time domain resource allocation informationPDSCH position set M for HARQ-ACK feedback in slot n_A,c. Then according to M_A,cAnd mapping the HARQ-ACK of the PDSCH received in the PDSCH position set to the corresponding position in the HARQ-ACK feedback sequence, thereby obtaining the HARQ-ACK codebook transmitted in the time slot n. Specifically, the UE determines the number of slots that need to be fed back in a slot on a carrier based on the HARQ feedback timing set configured by the higher layer signaling, and then determines the maximum number of PDSCHs that can be transmitted in each slot in the slots. If a semi-static slot structure is configured, candidate PDSCHs that do not satisfy the PDSCH transmission condition need to be removed based on the slot structure. When carrier aggregation exists, the HARQ-ACK codebook on each carrier needs to be determined according to the process, and finally the HARQ-ACK codebooks of different carriers are cascaded according to the carrier sequence to obtain the final HARQ-ACK codebook.

When configured to use the dynamic HARQ-ACK codebook, the UE determines a corresponding PDCCH detection position set based on a HARQ feedback timing set configured by a high-layer signaling and a scheduling timing relationship between a PDSCH and a PDCCH included in a configured time domain allocation resource table, and then determines the HARQ-ACK codebook with a downlink allocation index C-DAI and a total downlink allocation index T-DAI based on a count included in DCI received in the PDCCH detection position set.

Specifically, in the 5G NR, in the carrier aggregation CA scenario, when a carrier with an extended CP configuration and a carrier with a normal CP are aggregated, there is a case where slot boundaries are not aligned. According to the HARQ feedback timing of the current standard and the specification of the feedback codebook, there are some cases where a part of the timeslots do not have corresponding feedback positions in the feedback codebook. For example, when a terminal is configured to perform carrier aggregation using carrier 1 and carrier 2, where carrier 1 is a main carrier, and when the subcarrier spacing of carrier 1 is configured to be 60kHz and an extended CP configuration is used, and the subcarrier spacing of carrier 2 is also 60kHz but a conventional CP configuration is used, if only one value K1 in the configured HARQ feedback timing set is 2, and according to the provisions in the current standard, K1 ═ 0 indicates the last physical uplink control channel PUCCH transmission slot overlapping with the received physical downlink shared channel PDSCH, then as shown in fig. 2, K1 ═ 0 indicates that the PDSCH transmitted in slot n on carrier 2 corresponds to slot n +1 on carrier 1 for feedback, so that K1 ═ 2 corresponds to the PDSCH transmitted in slot n on carrier 2 for feedback corresponding to slot n +3 on carrier 1, and the PDSCH transmitted in slot n +1 on carrier 2 also feeds back on slot n +3 on carrier 1, however, according to the specification of the feedback codebook in the standard, for the PUCCH transmitted in slot n +3, only one corresponding downlink slot on carrier 2, that is, slot n +1, can be found according to the value K1 when determining the feedback codebook, so that the PDSCH transmitted in slot n on carrier 2 has no corresponding feedback position in the feedback codebook regardless of using the semi-static codebook or the dynamic codebook scheme, and it is necessary to consider modifying the existing HARQ feedback timing determination method.

As can be seen from the above, in the CA scenario, when a carrier with an extended CP configuration and a carrier with a normal CP are aggregated, there is a case where slot boundaries are not aligned. According to the HARQ feedback timing and feedback codebook determination scheme defined in the current standard, there are cases where a fractional slot does not have a corresponding feedback position in the feedback codebook.

Detailed Description

In order to make the technical problems, technical solutions and advantages of the present invention more apparent, the following detailed description is given with reference to the accompanying drawings and specific embodiments.

The present invention provides a transmission method for hybrid automatic repeat request acknowledgement HARQ-ACK information, which is applied to a terminal, and as shown in fig. 3, and includes:

Wherein, the determining the feedback time slot of the HARQ-ACK information corresponding to the HARQ-ACK information according to the preset rule includes: when the ending position of the preset channel is detected to be in the time slot n, determining the feedback time slot of the HARQ-ACK information corresponding to the preset channel according to a formula I;

wherein, the first formula is:

wherein, the first formula is:

The transmission method of the HARQ-ACK information provided in the embodiment of the present invention is further described below.

In view of the above technical problems, an embodiment of the present invention provides a method for transmitting HARQ-ACK information, which mainly involves: if the UE detects that the ending position is in a preset channel of a time slot n (namely if the UE detects that the time slot of the ending position of the preset channel is the time slot n), the UE sends HARQ-ACK information corresponding to the preset channel in a PUCCH of the time slot n + K, wherein K is a HARQ-ACK feedback time sequence, namely the time slot of the ending position of the preset channel and the time slot offset number of the HARQ-ACK information corresponding to the preset channel, and is a K1 value configured by a high layer or a K1 value indicated in DCI issued by network equipment; in the above description, the slot n is determined based on the PDSCH transmission carrier configuration information, the slot offset number indicated by k is determined based on the PUCCH transmission carrier configuration information, and the slot n + k is determined based on the PUCCH transmission carrier configuration information; the preset channel comprises a PDSCH or a PDCCH transmission indicating SPS PDSCH release;

specifically, the UE may determine the PUCCH transmission slot corresponding to k ═ 0 (i.e., the feedback slot of the HARQ-ACK information) based on any one of the following manners:

the first method is as follows: different HARQ-ACK information feedback timing sequence determination methods are used for different carrier aggregation conditions:

when the CP of the PUCCH transmission carrier (which may be a primary carrier) is configured as an extended CP configuration and the subcarrier spacing is 60kHz, if the CP of the transmission carrier of the preset channel is configured as a normal (i.e., non-extended) CP configuration and the subcarrier spacing is 60kHz or 120kHz, k ═ 0 corresponds to the first PUCCH transmission slot that overlaps with the slot where the end position of the preset channel is located; otherwise, k is 0 and corresponds to the last PUCCH transmission time slot overlapped with the time slot where the end position of the preset channel is located;

the second method comprises the following steps: the same HARQ-ACK information feedback timing determination method is used for different carrier aggregation conditions:

and k is 0, which corresponds to the PUCCH transmission time slot overlapped with the time slot at which the end position of the preset channel is positioned.

Furthermore, according to the PUCCH transmission slot corresponding to the mode one or mode two determined that k is 0, the PUCCH transmission slot corresponding to k that is not 0 is determined.

Regarding the network device, the HARQ-ACK information feedback timing sequence is determined in the same manner as the UE, which is not described herein again; and further the network equipment receives the HARQ-ACK information according to the determined HARQ-ACK information feedback time sequence. However, K is a value K1 determined by the network device and sent to the terminal through higher layer signaling or DCI.

The scheme provided by the embodiment of the invention is illustrated below. Suppose that: the terminal is configured to perform carrier aggregation using carrier 1, carrier 2, carrier 3 and carrier 4, where carrier 1 is a main carrier, the subcarrier spacing of carrier 1 is configured to be 60kHz and uses extended CP configuration, the subcarrier spacing of carrier 2 is 60kHz and uses normal CP configuration, the subcarrier spacing of carrier 3 is 120kHz and uses normal CP configuration, the subcarrier spacing of carrier 4 is 30kHz and uses normal CP configuration, and if only one value K1 included in the configured HARQ feedback timing set is 2, then:

when determining the HARQ feedback timing using mode one, as shown in fig. 5:

for the PDSCH received by the terminal on carrier 2, K1 ═ 0 corresponds to the first PUCCH transmission slot overlapping with the slot where the end position of the preset channel is located, and the terminal determines the PUCCH transmission slot corresponding to K1 indicated by the actual DCI or the K1 value configured in the higher layer with K1 ═ 0 as a reference point, that is, for the PDSCH received by the terminal in slot 2n on carrier 2, K1 ═ 0 corresponds to slot 2n on carrier 1, and then K1 ═ 2 corresponds to slot 2n +2 on carrier 1; for a PDSCH received by a terminal in slot 2n +1 on carrier 2, K1 ═ 0 corresponds to slot 2n +1 on carrier 1, then K1 ═ 2 corresponds to slot 2n +3 on carrier 1;

for the PDSCH received by the terminal on carrier 3, K1 ═ 0 corresponds to the first PUCCH transmission slot overlapping with the slot where the end position of the preset channel is located, and the terminal determines the PUCCH transmission slot corresponding to K1 indicated by the actual DCI or the K1 value configured in the higher layer with K1 ═ 0 as a reference point, that is, for the PDSCH received by the terminal in slot 4n and slot 4n +1 on carrier 3, K1 ═ 0 corresponds to slot 2n on carrier 1, and K1 ═ 2 corresponds to slot 2n +2 on carrier 1; for PDSCH received by the terminal in slot 4n +2 and slot 4n +3 on carrier 3, K1 ═ 0 corresponds to slot 2n +1 on carrier 1, then K1 ═ 2 corresponds to slot 2n +3 on carrier 1;

for the PDSCH received by the terminal on carrier 4, K1 ═ 0 corresponds to the last PUCCH transmission slot overlapping with the slot where the end position of the preset channel is located, and the terminal determines the PUCCH transmission slot corresponding to K1 indicated by the actual DCI or the K1 value configured in the higher layer with K1 ═ 0 as a reference point, that is, for the PDSCH received by the terminal in slot n on carrier 4, K1 ═ 0 corresponds to slot 2n +1 on carrier 1, and K1 ═ 2 corresponds to slot 2n +3 on carrier 1;

when determining the HARQ feedback timing using mode two, as shown in fig. 6:

for the PDSCH received by the terminal on carrier 4, K1 ═ 0 corresponds to the first PUCCH transmission slot overlapping with the slot where the end position of the preset channel is located, and the terminal determines the PUCCH transmission slot corresponding to K1 indicated by the actual DCI or the K1 value configured in the higher layer with K1 ═ 0 as a reference point, that is, for the PDSCH received by the terminal in slot n on carrier 4, K1 ═ 0 corresponds to slot 2n on carrier 1, and K1 ═ 2 corresponds to slot 2n +2 on carrier 1.

It can be known from the above that, the scheme provided by the embodiment of the present invention mainly aims at how to determine the HARQ-ACK information feedback timing to perform HARQ-ACK information transmission when a carrier with an extended CP configuration and a carrier with a normal CP are aggregated in a CA scenario.

Therefore, the embodiment of the present invention provides a method for transmitting HARQ-ACK information, so that in a CA scenario, when a carrier with an extended CP configuration and a carrier with a normal CP are aggregated, there is no longer a problem in the prior art that a part of time slots have no corresponding feedback position in a feedback codebook and cannot be fed back according to the HARQ feedback timing and the specification of the feedback codebook of the current standard.
