Problems solved by technology

[0005] However, the total number of bits of AN / SR and CSI is not fixed, so that the base station does not know in which PUCCH resource set the UE will select PUCCH resources to transmit AN / SR and CSI, resulting in the need for the base station to perform blind detection

Embodiment 1

[0038] figure 2 It is a schematic flowchart of a method for determining physical uplink control channel resources provided by an embodiment of the present invention. The methods include:

[0039] Step S210, determine the number of reference bits of CSI-part 2 according to preset rules.

[0040] Step 220, according to the reference bit number of CSI-part 2, determine the sum of the reference bit numbers of AN / SR and CSI.

[0041] Wherein, the CSI includes at least: CSI-part 1 and CSI-part 2.

[0042] Step 230: Determine the target PUCCH resource set according to the sum of reference bits of AN / SR and CSI.

[0043] In practical applications, if the PUCCH for transmitting AN / SR and the PUCCH for transmitting CSI have the same start symbol, the UE may select one PUCCH resource to transmit AN / SR and CSI.

[0044] It should be noted that AN / SR means that AN is included, and SR may or may not be included.

Embodiment 2

[0113] Figure 5 It is a schematic flowchart of another method for determining physical uplink control channel resources provided by an embodiment of the present invention. The methods include:

[0114] Step 510, if the CSI includes CSI-part 2, then determine the preset PUCCH resource set as the target PUCCH resource set.

[0115] The UE and the base station determine a preset PUCCH resource set, so that if the PUCCH transmitting AN / SR and the PUCCH transmitting CSI have the same start symbol, and the CSI includes CSI-part 2, the preset PUCCH resource set can be determined is the target PUCCH resource set, so that the base station and UE have the same understanding of the PUCCH resource set for transmitting AN / SR and CSI.

[0116] Optionally, compared with other PUCCH resource sets, the preset PUCCH resource set has the largest number of UCI bits.

[0117] For example, RESET3 that can bear the largest number of UCI bits is determined as the preset PUCCH resource set.

[0136] Optionally, preset rules include:

[0137] According to the number of bits of CSI-part 2 corresponding to different RIs, the number of reference bits of CSI-part 2 is determined.

[0138] Optionally, the reference bit number of CSI-part 2 is the minimum number of bits among t...

Abstract

The embodiment of the invention discloses a physical uplink control channel resource determination method and communication equipment, and the method comprises the steps: determining the reference bitnumber of CSI-part 2 according to a preset rule; according to the reference bit number, determining the sum of the reference bit number of the AN / SR and the reference bit number of the CSI, whereinthe CSI at least comprises CSI-part 1 and CSI-part 2; and determining a target PUCCH resource set according to the sum of the reference bit numbers. According to the embodiment of the invention, the PUCCH resource set used for transmitting the AN / SR and the CSI can be accurately determined, and the blind detection problem of the base station is effectively avoided.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method for determining physical uplink control channel resources and a communication device. Background technique [0002] In the physical uplink control channel (Physical Uplink Control Channel, PUCCH) of the transmission feedback information (HARQ-ACK / NACK, AN) / scheduling request (Scheduling Request, SR) and the PUCCH of the transmission channel state signal (Channel State Information, CSI) In the case of overlapping time domain positions, if the PUCCH for transmitting AN / SR and the PUCCH for transmitting CSI have the same start symbol, the terminal equipment (User Equipment, UE) will select a PUCCH resource to transmit AN / SR and CSI. [0003] In mobile communication New Radio (NR), PUCCH resources are divided into different PUCCH resource sets (PUCCH ResourceSet, PUCCH RESET) according to the size that can carry uplink control information (Uplink Control Information, UCI). ...
