Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, a terminal, and a network device for determining and indicating a hybrid automatic repeat request codebook.
Background
The New wireless (NR) system includes two Hybrid Automatic Repeat Request (HARQ) feedback codebooks: a semi-static codebook (Type-1 HARQ codebook) and a dynamic codebook (Type-2 HARQ codebook).
The semi-static codebook is constructed as follows:
for a Physical Uplink Control Channel (PUCCH) carried by a certain Uplink slot or sub-slot (slot), a User Equipment or terminal (UE) determines to be a series of Physical Downlink Shared Channels (PDSCH) transmission timing feedback HARQ-ACKs according to the following information:
1) a time value K1(a set of slot/sub-slot timing values K1) for a set of slots or sub-slots;
2) a TDRA table configured by a physical downlink shared channel-Time Domain Resource Allocation List (PDSCH-Time Domain Resource Allocation List) by a high layer;
3) semi-static frame structure configurations, such as: configuring a K1 set, taking sub-slot as a unit, where K1 ═ {1,2,3,4,5,6,7,8}, and for PUCCH included in UL sub-slot n and UL sub-slot n +1, feeding back HARQ-ACK corresponding to pdsch(s) as follows:
PUCCH on Sub-slot n: feeding back HARQ ACK of PDSCH(s) corresponding to UL sub-slot n-1-UL sub-slot n-8;
PUCCH on Sub-slot n + 1: feeding back HARQ-ACK of PDSCH(s) corresponding to UL sub-slot n-7;
and whether the PDSCH transmission is really available or not, the HARQ-ACK is fed back as long as the effective transmission opportunity exists;
if the same downlink time slot supports more than one unicast PDSCH for receiving, the number of HARQ-ACK bits to be reserved for the downlink time slot is determined as follows:
step 1: traversing the TDRA table, finding out a row with the minimum ending symbol, and reserving 1 bit;
step 2: the following is removed from the TDRA table thereafter: the row with the smallest end symbol and the row with the beginning symbol earlier than the end symbol are assigned the same value
And step 3: steps 1,2 are performed on the remaining rows of the TDRA table.
As shown in FIG. 1, according to the generation of Type-1 HARQ codebook, only one HARQ-ACK bit is reserved for two shaded rows, and therefore, the value assigned to one HARQ-ACK bit is the same value
The UE does not expect to receive more than one PDSCH, otherwise the UE may be confused when constructing the HARQ-ACK codebook.
When the same terminal multiplexes multiple services, different services coexist in the same terminal, for example, the terminal integrates a triple-remote service, a differential protection service and a network time service, and the internet-connected unmanned aerial vehicle integrates two services, namely control information and audio and video, but the requirements of different services on time delay, reliability and data rate are greatly different.
The following scenario will therefore exist: a base station schedules a PDSCH of an enhanced mobile broadband (eMMC) service in slot n symbols # 0-13, but at the moment, ultra-reliable and low-delay communication (URLLC) data arrive, and schedules the PDSCH of the URLLC in slot n symbols # 2-3 in order to ensure the delay of the URLLC data;
according to the construction method of the Type-1 HARQ codebook, only one bit is reserved for transmitting HARQ-ACK for the PDSCH of the eMBB and the URLLC, so that the UE generates confusion when constructing the HARQ codebook.

Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

in one row of the TDRA table, there are included: the row index, the PDSCH mapping type (mappingType), K0, the starting symbol s (starting symbol), the length l (length), and the corresponding HARQ codebook, and specifically, the configuration results of the HARQ codebook corresponding to the row index, the K0, the mapping type, the starting symbol, and the length are as follows:
the method comprises the steps of determining a PDSCH time domain resource allocation table of a physical downlink shared channel, wherein the PDSCH time domain resource allocation table comprises at least one PDSCH time domain resource allocation message, the PDSCH time domain resource allocation message at least comprises first information and second information, the first information is used for indicating a hybrid automatic repeat request (HARQ) codebook, and the second information is used for indicating PDSCH time domain resources. Therefore, disorder generated when the UE constructs the HARQ codebook is avoided, and the applicability of the Type-1 HARQ codebook to a UE multi-service multiplexing scene is improved.
In an alternative embodiment of the present invention, step 22 may comprise:
step 221, determining a row index set of the PDSCH time domain resource allocation table required by the hybrid automatic repeat request codebook to be constructed according to the first information and the second information.
Optionally, step 221 may include: and determining a row index set corresponding to PDSCH time domain resource allocation information and the HARQ codebook indicated by the first information is the same as the HARQ codebook to be constructed as a row index set of a PDSCH time domain resource allocation table required by the hybrid automatic repeat request codebook to be constructed.
In an implementation manner of this step, initializing a row index set R of a PDSCH time domain resource allocation table required by the hybrid automatic repeat request codebook to be constructed as an empty set, traversing a row index corresponding to each PDSCH time domain resource allocation information included in the PDSCH time domain allocation table, and for any row index R:
a) if the HARQ codebook indicated by the first information is the same as the HARQ codebook to be constructed, adding the row index R into a row index set R of a PDSCH time domain resource allocation table required by the hybrid automatic repeat request codebook to be constructed;
b) if the HARQ codebook indicated by the first information is different from the HARQ codebook to be constructed, judging a row index r +1, and continuing to execute the steps of a) and b).
In this optional embodiment, for each HARQ codebook, corresponding to at least two rows in the row index set R of the PDSCH time domain resource allocation required by the HARQ codebook to be constructed, the terminal does not expect to receive more than one PDSCH in the same downlink timeslot or the same downlink sub-timeslot, and the candidate PDSCH receiver opportunity indexes corresponding to the more than one PDSCH are the same.
In another alternative embodiment of the present invention, step 22 may comprise:
step 222, taking a row index corresponding to each PDSCH time domain resource allocation information in the PDSCH time domain resource allocation table as a row index set R required by the HARQ codebook to be constructed;
in step 223, for any row index R in the set R, if the HARQ codebook indicated by the first information is different from the HARQ codebook to be constructed, R is removed from the set R.
In the implementation manner of this step, the row indexes in the row index set R are traversed, and for any row index R:
a) if the HARQ codebook indicated by the first information is different from the HARQ codebook to be constructed, removing R from the set R;
b) if the HARQ codebook indicated by the first information is the same as the HARQ codebook to be constructed, continuing to judge the row index r +1 and continuing to execute the steps a) and b).
In this alternative embodiment, for each HARQ codebook, corresponding to at least two rows in the row index set R of the PDSCH time domain resource allocation required by the HARQ codebook to be constructed, the terminal does not expect to receive more than one PDSCH in the same downlink timeslot or the same downlink sub-timeslot, and the candidate PDSCH receiver opportunity indexes corresponding to the more than one PDSCH are the same.
For example, when the terminal constructs a semi-static codebook, for example, when the terminal constructs HARQ codebook 1:
a terminal receives a TDRA table predefined by a protocol or configured through high-level signaling and HARQ codebook indication information;
according to the received TDRA table and HARQ codebook indication information, selecting the HARQ codebook indication information in the TDRA table as the configuration/row of 'codebook 1', forming a TDRA table 'configuration set' or 'row set' R which needs to be traversed for constructing a semi-static codebook, and then constructing according to the semi-static codebook construction step.
In another implementation manner, the UE determines slot/sub-slot and/or PUCCH (physical uplink control channel) resources carrying a first HARQ codebook by receiving a high layer signaling and/or physical layer downlink control information sent by the base station;
for assignment of the same br,k,nDThe method comprises the steps that the candidate PDSCH receiving opportunities are determined to be the same in slot (time slot)/sub-slot (sub-time slot) and/or PUCCH resources bearing a first HARQ codebook according to high-level signaling sent by a base station and/or physical layer downlink control information for scheduling the PDSCHs, and UE does not expect to receive more than one PDSCH in the same slot/sub-slot;
as shown in fig. 3, the PDSCH 1 scheduled by the base station for eMBB in the second DL slot is transmitted in symbols #0 to # 13, along with arrival of URLLC (ultra-reliable, low-delay communication) data, and the base station also schedules PDSCH 2 of URLLC in symbols # 2 to # 3 of the second DL slot in order to ensure delay of URLLC traffic. Determining a first HARQ codebook as an HARQ codebook 1 transmitted by a PUCCH on the last UL slot through a high-level signaling sent by a base station and/or physical layer downlink control information of a scheduling eMBB (enhanced mobile broadband) PDSCH 1; and determining the first HARQ codebook as the HARQ codebook 2 transmitted by the PUCCH on the sub-slot 1 on the last UL slot according to high-level signaling sent by the base station and/or physical downlink control information of a scheduling URLLC PDSCH 2. The UE does not expect the two first HARQ codebooks to be the same;
the URLLC service and the eMBB service are only an example, and may also be two URLLC services with different delay requirements, or two eMBB services with different delay requirements.
The two first HARQ codebooks are used for carrying HARQ-ACK information of the PDSCHs. Here, the PDCCH scheduling PDSCH may indicate the slot/PUCCH where its HARQ-ACK is located, and the PUCCH carries the HARQ codebook, but the HARQ codebook carried by the slot/PUCCH that is not indicated by the PDCCH scheduling PDSCH may also need to carry HARQ-ACK information of the PDSCH, which is determined by the characteristics of the semi-static codebook.
According to the embodiment of the invention, the HARQ-ACK information of the overlapped PDSCHs is indicated to different HARQ codebooks through the high-layer signaling and the physical layer downlink control information, the disorder of the UE in constructing the HARQ codebooks is avoided, and the applicability of the Type-1 HARQ codebook to an intra-UE multi-service multiplexing scene is improved.
The embodiment of the invention also provides an indication method of a hybrid automatic repeat codebook, which is applied to network equipment and comprises the following steps:
