Embodiment 1

[0053] Such as image 3 As shown, the terminal is configured with P-CSI or SP-CSI on PUCCH transmission on the primary cell (Pcell), and at the same time, there is PUSCH transmission on another secondary cell (Scell). PUCCH is transmitted on component carrier 0 (CC0), and PUSCH It is transmitted on CC1, and the uplink grant (UL grant) corresponding to the PUSCH triggers an A-CSI report, and the PUCCH and PUSCH transmissions overlap in the time domain, then the UE discards the PUCCH and its CSI report, and only transmits the PUSCH and its A-CSI report. -CSI.

Embodiment 2

[0055] Such as figure 1 As shown, the UE configures four CSI transmissions in one slot, specifically P-CSI0, P-CSI1, P-CSI2 and SP-CSI on PUCCH, and the corresponding priority order is: SP-CSI>P-CSI0 >P-CSI1>P-CSI2. The resources of P-CSI1 and P-CSI2 overlap in the time domain, the resources of P-CSI0 and SP-CSI on PUCCH overlap in the time domain, and the resources of P-CSI 1 and P-CSI2 and SP-CSI on PUCCH are both There is no overlap, and the UE is configured with a multi-CSI physical uplink control channel resource list (multi-CSI-PUCCH-Resource List). Then the UE multiplexes all CSI reports (including SP-CSI on PUCCH, P-CSI0, P-CSI1 and P-CSI2) in the slot on a PUCCH resource configured in the multi-CSI physical uplink control channel resource list. If the maximum code rate of the PUCCH resource is exceeded, the UE discards some CSI reports according to the priority.

Embodiment 3

[0057] Such as Figure 4 As shown, the UE is configured with P-CSI or SP-CSI on PUCCH transmission in a slot, and its corresponding priority order is: SP-CSI>P-CSI, and P-CSI and SP-CSI are located in the resource time domain There is overlap, and the UE is configured with multi-CSI-PUCCH-Resource List. Then the UE multiplexes all CSI reports (including SP-CSI and P-CSI) in the slot on a PUCCH resource configured in the multi-CSI-PUCCH-Resource List. If the maximum code rate of the PUCCH resource is exceeded, the UE Some CSI reports are discarded according to priority.

[0058] In the information transmission method of the embodiment of the present invention, the physical channel corresponding to the first CSI report is a physical uplink control channel PUCCH, the physical channel corresponding to the second CSI report is a PUCCH, and multiple CSI physical uplink control channel resources are configured In the case of the multi-CSI physical uplink control channel resource li...

Abstract

The present invention provides an information transmission method and a terminal, including: when resources overlap between the first channel state information CSI report and the second CSI report, perform the following operations: if the physical channel corresponding to the first CSI report is a physical The uplink control channel PUCCH, the physical channel corresponding to the second CSI report is PUCCH, and the multi-CSI physical uplink control channel resource list is configured, then the CSI report with overlapping resources occurs according to the resource transmission in the multi-CSI physical uplink control channel resource list and/or, if the physical channel corresponding to the first CSI report is PUCCH and the physical channel corresponding to the second CSI report is the physical uplink shared channel PUSCH, and the PUCCH and PUSCH are transmitted on different carriers, discard the PUCCH and the CSI report carried by the PUCCH, and transmit the PUSCH and the CSI report carried by the PUSCH.

Description

technical field [0001] The present invention relates to the technical field of communication applications, in particular to an information transmission method and a terminal. Background technique [0002] Compared with previous mobile communication systems, future mobile communication systems need to adapt to more diverse scenarios and business requirements. The main scenarios of New Radio (NR) include Mobile Broadband Enhancement (Enhance MobileBroadband, eMBB), Massive Machine Type of Communication (mMTC), and Ultra Reliable Low Latency (URLLC). Different requirements are put forward in terms of high reliability, low latency, large bandwidth, and wide coverage. [0003] The PUCCH for transmitting CSI is configured by the high-level layer and sent periodically or periodically after activation. Due to the flexible start symbol position and flexible length, there may be a situation where PUCCH and PUSCH overlap in time (the time domain occupied by PUCCH and PUSCH OFDM symbo...
