Description

HARQ-ACK codebook transmission method, device and storage medium

Technical Field

The present invention relates to the field of communications, and in particular, to a method, an apparatus, and a storage medium for HARQ-ACK codebook transmission.

Background

In order to better meet the increasing demands of Service types, in new access technologies, such as the fifth generation mobile communication technology (5G), Multicast and Broadcast Service (MBS), unicast Service (unicast), and the like are supported.

In the 5G mobile communication system, in order to ensure reliability and transmission efficiency of data transmission, a Hybrid Automatic Repeat reQuest (HARQ) is used, and the basic principle of the HARQ can be understood as follows: the receiving end feeds back the decoding result of the data received from the sending end to the sending end, the correct decoding is fed back to be positive Acknowledgement (ACK), and the incorrect decoding is fed back to be Negative Acknowledgement (NACK). If the sending end receives the ACK, new data can be transmitted to the receiving end; if the transmitting end receives NACK, the data may be retransmitted to the receiving end.

The problem to be solved is how to effectively implement HARQ feedback when multicast broadcast services and unicast services coexist.

Last (Last) Downlink Control Information (DCI): the terminal determines a Physical Uplink Control Channel resource Indicator (PRI) based on Last DCI, and the PUCCH is fully spliced into a Physical Uplink Control Channel.

Fig. 1 is a schematic diagram of a Last DCI determination method; as shown in fig. 1, in versions R15 and R16 of a New air interface (NR) system, a method for determining Last DCI includes:

sequencing all DCIs which are indicated to the same slot and fed back by Hybrid Automatic Repeat request (HARQ-ACK) specifically comprises the following steps: firstly, sorting according to the ascending order (namely from first to last) of the PDCCH Monitoring Occasions (MO); then, for the Last PDCCH monitoring occasion after sequencing, sequencing is performed according to the ascending order (i.e. from small to large) of the serving cell index (serving cell index), and the Last DCI is determined based on the sequencing result. Here, the determined PUCCH resource indicated by the Last DCI is used to transmit HARQ-ACK feedback information.

In versions R15 and R16 of NR systems, a method of determining a semi-static codebook (Type-1) includes:

The number of bits (bits) of HARQ-ACK for each PDSCH reception opportunity in the PDSCH reception opportunity set may be determined jointly according to a HARQ-ACK-SpatialBundlingPUCCH parameter, a maximum codeword, and a Code Block Group (CBG) configuration parameter.

Wherein, the K1 set is a time relationship (Timing between DL data reception and correlation feedback) between downlink data transmission and corresponding HARQ codebook feedback; may be fixed as {0,1,2,3,4,5,6,7,8}, or may be determined by a higher layer parameter dl-datatoll-ACK, which may be any 1-8 of (0, …, 15).

As shown in FIG. 2, a diagram of a semi-static codebook determination method, the K1 set may be {1,2,3,4 }. Specifically, the K1 set may be configured by the base station to be a K1 value set, such as {1,2,3,4}, and sent to the terminal through RRC signaling. And then sending DCI to the terminal, so as to inform the terminal of which of the sets the allocated K1 for the data transmission specifically takes value. The frame structure may be: DDDUU structure.

In versions R15 and R16 of the NR system, a method of determining a dynamic codebook (Type-2) includes:

step 1, determining PDSCH receiving time according to a counter downlink assignment index (C-DAI) and a total downlink assignment index (T-DAI) indicated in DCI; generating a codebook based on the determined PDSCH reception occasion;

the C-DAI value represents the accumulated number of PDSCHs scheduled by DCI till the current service cell and the current PDCCH detection opportunity; sequencing according to the service cell index in an ascending order, and then sequencing according to the PDCCH detection time in an ascending order;

the T-DAI value represents the total number of PDSCHs scheduled by the DCI at the current PDCCH detection opportunity.

For the bit number of the HARQ-ACK of each PDSCH receiving opportunity, the bit number can be determined jointly according to the HARQ-ACK-spatial bundling PUCCH parameter and the maximum code word;

and 2, placing HARQ-ACK of semi-persistent scheduling (SPS) at the tail of the generated codebook.

If some Control Channels (CC) start CBG, the codebook is divided into 2 parts, wherein the first part carries the PDSCH scheduled by SPS and DCI 1_0 of a cell starting CBG and the HARQ-ACK corresponding to the PDSCH scheduled by DCI 1_0 and 1_1 of a cell not starting CBG; and the second part carries HARQ-ACK corresponding to the PDSCH scheduled by the DCI 1_1 of the starting CBG cell. As shown in fig. 3 (b).

With respect to DAI, the number of bits is defined as follows:

4 bits: if a plurality of serving cells are configured in a downlink (DL, Down) and a higher layer parameter pdsch-harq-ack-codebook is dynamic type, 2 Most Significant Bits (MSB) thereof are C-DAI and 2 Least Significant Bits (LSB) thereof are T-DAI;

2 bits: if only one serving cell is configured in the DL and the high-level parameter pdsch-harq-cck-codebook is dynamic, 2bits is C-DAI;

0 bits: other situations.

FIG. 3(a) and FIG. 3(b) are schematic diagrams of a dynamic codebook determination method; the generation method of the dynamic codebook will be described in detail with reference to fig. 3(a) and 3 (b).

The base station may determine a PDSCH receiving timing according to a total downlink assignment index (T-DAI) and a counter downlink assignment index (C-DAI), determine HARQ feedback information based on the determined PDSCH receiving timing, and generate a corresponding dynamic codebook.

By the second method, the DCI indicated by the PDCCH of the unicast service (unicast) is adopted as much as possible to determine the PUCCH resources, so that the first communication equipment (such as UE) in the MBS group does not need to be fully configured as orthogonal PUCCH resources, and only the PUCCH resources of the UE needing the HARQ-ACK feedback by the PUCCH scheduled by the G-RNTI need to be orthogonal.
