Description
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a feedback method and apparatus for uplink control information, and a user equipment.
Background
The Uplink Control Information (UCI) includes SR (Scheduling Request), HARQ-ACK (Hybrid Automatic Repeat Request ACK, Hybrid Automatic Repeat Request acknowledgement), and CSI (Channel State Information). SR is used to request uplink UL-SCH (uplink shared channel) resources from a base station; HARQ-ACK performs HARQ acknowledgement for Downlink data transmitted on a PDSCH (Physical Downlink Shared Channel); the CSI includes information such as CQI (Channel Quality Indicator), PMI (Precoding Matrix Indicator), RI (Rank Indication), and the like, and is used to tell the base station about downlink Channel Quality, and the like, so as to assist the base station in downlink scheduling. If the UE is not allocated Uplink resources for transmitting UL-SCH data in the current subframe, the UE transmits Uplink Control information using a PUCCH (Physical Uplink Control Channel).
The PUCCH is one physical channel of an uplink in an NR (New Radio, New air interface) system, and carries uplink control information therein. The PUCCH formats are shown in table 1, where the number of OFDM symbols occupied by PUCCH formats 1 and 3 is large, and are referred to as long PUCCH.
TABLE 1
| PUCCH format | Length in OFDM symbols | Number of bits |
| 0 | 1–2 | ≤2 |
| 1 | 4–12 | ≤2 |
| 2 | 1–2 | >2 |
| 3 | 4–12 | >2 |
In a 3rd Generation Partnership Project (3 GPP) LTE (Long Term Evolution) system, a UE can only send one PUCCH in one subframe, and simultaneous transmission of multiple PUCCHs in one subframe does not occur. However, in the NR system, it is possible for the UE to transmit two PUCCHs, such as one long PUCCH, one short PUCCH, or two short PUCCHs, in a TDM (Time Division Multiplexing) manner within one subframe. There is no solution on how the uplink control information should be allocated in different PUCCHs at this time.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
An embodiment of the present invention provides a feedback method for uplink control information, and as shown in fig. 1, the method includes:
s11, when two PUCCHs exist in the UE in one time slot, judging whether the total bit number of the first type of uplink control information and the second type of uplink control information is less than or equal to a first PUCCH resource for feeding back the first type of uplink control information or a second PUCCH resource for feeding back the second type of uplink control information.
And S12, when the total bit number of the first type of uplink control information and the second type of uplink control information is less than or equal to a second PUCCH resource for feeding back the second type of uplink control information, feeding back the first type of uplink control information on the first PUCCH resource, and repeatedly feeding back the first type of uplink control information on the second PUCCH resource.
And S13, when the total bit number of the first type of uplink control information and the second type of uplink control information is less than or equal to the first PUCCH resource for feeding back the first type of uplink control information, feeding back the second type of uplink control information on the second PUCCH resource, and repeatedly feeding back the second type of uplink control information on the first PUCCH resource.
In the feedback method of uplink control information provided in the embodiment of the present invention, when two PUCCHs exist in a UE in one slot, when the total number of bits of two types of uplink control information is less than or equal to a second PUCCH resource for feeding back second type of uplink control information, the first type of uplink control information is fed back on the first PUCCH resource, and the first type of uplink control information is repeatedly fed back on the second PUCCH resource, and when the total number of bits of the two types of uplink control information is less than or equal to the first PUCCH resource for feeding back the first type of uplink control information, the second type of uplink control information is fed back on the second PUCCH resource, and the second type of uplink control information is repeatedly fed back on the first PUCCH resource. Compared with the prior art, the invention can realize that the uplink control information is repeatedly sent on the two PUCCHs when the UE has the two PUCCHs in one time slot, thereby improving the feedback performance of the uplink control information and enhancing the coverage without influencing the capacity of an uplink control channel.
In the embodiment of the invention, PUCCH resources for the UE to feed back the HARQ-ACK and the SR are called HARQ-PUCCH resources, and PUCCH resources for the UE to feed back the CSI and the SR are called CSI-PUCCH resources.
When two PUCCHs exist in a UE in one slot, there may be two combination modes as follows, and the corresponding solution is:
combination 1:
one is a HARQ-PUCCH resource for feeding back HARQ-ACK, and one is a CSI-PUCCH resource for feeding back CSI.
The first scheme is as follows: the HARQ-ACK information is not only fed back on the HARQ-PUCCH resource, but also multiplexed with the CSI-PUCCH resource for repeated feedback of the HARQ-ACK information.
Scheme II: and part or all of the CSI information is fed back on the CSI-PUCCH resources, and the HARQ-PUCCH resources are multiplexed with the HARQ-ACK information to perform repeated feedback of part or all of the CSI information. And if only part of CSI information is repeatedly fed back, the rest CSI information is only fed back on the CSI-PUCCH resource.
And (3) combination 2:
one for feeding back slot-scheduled HARQ-PUCCH resources and the other for feeding back non-slot-scheduled HARQ-PUCCH resources. For simplicity, the HARQ-PUCCH resource for feeding back slot-scheduled is HARQ-PUCCH 1, and the HARQ-PUCCH resource for feeding back non-slot-scheduled is HARQ-PUCCH 2
The first scheme is as follows: slot-scheduled HARQ-ACK is not only fed back on HARQ-PUCCH 1 resources, but is repeated on HARQ-PUCCH 2 resources.
Scheme II: non-slot-scheduled HARQ-ACK is not only fed back on HARQ-PUCCH 1 resources, but also is repeatedly fed back on HARQ-PUCCH 2 resources.
The following describes the feedback method of uplink control information according to the present invention in detail with reference to specific embodiments.

And if the number of information bits M which can be carried by the CSI-PUCCH resources is less than or equal to the number of information bits M which can be carried by the CSI-PUCCH resources, the HARQ-ACK information is repeatedly fed back on the CSI-PUCCH.
