[0133] like figure 1 As shown, the embodiment of the present invention provides a UCI processing method, which is applied to a terminal, and specifically includes the following steps:

[0134] Step 11: When the first PUCCH resource bearing the first UCI does not overlap with the second PUCCH resource bearing the second UCI in the time domain, the first PUCCH resource and the third PUCCH resource bearing the third UCI overlap in the time domain do not overlap, and the second PUCCH resource and the third PUCCH resource overlap in the time domain: if the fourth PUCCH resource used to simultaneously transmit the second UCI and the third UCI is the same as the first PUCCH resource If PUCCH resources overlap, the first target UCI is discarded; wherein, the first target UCI is one of the second UCI and the third UCI.

[0135] Specifically, when the first PUCCH resource bearing the first UCI does not overlap with the second PUCCH resource bearing the second UCI in the time domain, th...

[0139] like figure 2 As shown, the embodiment of the present invention also provides a UCI processing method, which is applied to a terminal, and specifically includes the following steps:

[0140] Step 21: When the first PUCCH resource and the second PUCCH resource do not overlap in the time domain, the first PUCCH resource and the third PUCCH resource do not overlap in the time domain, and the second PUCCH resource When the resource and the third PUCCH resource overlap in the time domain: according to a predefined multiplexing transmission rule, determine a fourth PUCCH resource for simultaneously transmitting the second UCI and the third UCI.

[0141] Optionally, according to a pre-defined multiplexing transmission rule, determining the fourth PUCCH resource for simultaneous transmission of the second UCI and the third UCI may further specifically include: according to the type of the second UCI and / or transmitting the fourth PUCCH resource. The PUCCH format used by the s...

[0199] The above-mentioned first embodiment and the second embodiment respectively introduce the UCI processing method of the present invention, and the following embodiment will further describe its corresponding terminal with reference to the accompanying drawings.

[0200] Specifically, such as image 3 As shown, the embodiment of the present invention provides a terminal 300, including:

[0201] The processing module 310 is configured to, when the first physical uplink control channel PUCCH resource bearing the first UCI and the second PUCCH resource bearing the second UCI do not overlap in time domain, the first PUCCH resource and the second PUCCH resource bearing the third UCI When the three PUCCH resources do not overlap in the time domain, and the second PUCCH resource and the third PUCCH resource overlap in the time domain: if the fourth PUCCH resource used to simultaneously transmit the second UCI and the third UCI If the PUCCH resource overlaps with the first PUCCH...

Abstract

The present invention provides a method for processing uplink control information UCI, a terminal and a base station, wherein the method for processing UCI on the terminal side includes: when the first physical uplink control channel PUCCH resource carrying the first UCI and the first physical uplink control channel PUCCH resource carrying the second UCI The two PUCCH resources do not overlap in the time domain, the first PUCCH resource and the third PUCCH resource carrying the third UCI do not overlap in the time domain, and the second PUCCH resource and the third PUCCH resource overlap in the time domain: if When the fourth PUCCH resource that simultaneously transmits the second UCI and the third UCI overlaps with the first PUCCH resource, the first target UCI is discarded; wherein, the first target UCI is one of the second UCI and the third UCI. The present invention can avoid that due to the overlap of the second PUCCH resource and the third PUCCH resource, the UCI carried by the originally non-overlapping PUCCH resource needs to be transmitted on one PUCCH resource, thereby avoiding affecting the transmission delay and the transmission delay of the first UCI and the second UCI. transmission performance.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a processing method, terminal and base station for uplink control information UCI. Background technique [0002] In the fifth-generation mobile communication technology new air interface (5th-Generation New Radio, 5G NR), it supports sub-slot-based hybrid automatic repeat request acknowledgment (Hybrid automatic repeat request acknowledgment, HARQ- ACK) information transmission, used to support ultra-reliable and low latency communication (Ultra-Reliable and Low Latency Communications, URLLC) service feedback information transmission, so as to reduce transmission delay. When a terminal supports multiple services, such as URLLC and Enhanced Mobile Broadband (eMBB) services at the same time, a physical uplink control channel (Physical Uplink Control Information, UCI) carrying uplink control information (Uplink Control Information, UCI) of different services may appea...
