Embodiment Construction

[0109] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0110] First, some concepts mentioned in the embodiments of the present invention are described as follows.

[0111]When the uplink control information is multiplexed and transmitted on the PUSCH, a clear mapping rule has been defined, for example: HARQ-ACK follows the first frequency domain and then the time domain after the first DMRS (Demodulation Reference Signal, demodulation reference signal) symbol Mapping in sequence; CSI part 1 and CSI part 2 map from the first available RE (ResourceElement, resource element) resource in the frequency domain first and then time domain; if UCI (Uplink Control Information, uplink control information) occupies If the RE resources do not occupy a whole OFDM (Orthogonal Frequency Division Multiplexing, Orthogona...

Abstract

The invention provides an information transmission method, a reception method, a terminal and a network device, and relates to the technical field of communication. The information transmission method includes: when the transmission of the target physical uplink control channel PUCCH and the physical uplink shared channel PUSCH conflict, in the time slot where the conflict occurs, multiplexing the uplink control information in the target PUCCH on the PUSCH for transmission, or Discarding the PUSCH only transmits the uplink control information in the target PUCCH. In the above scheme, when the multi-slot PUCCH and PUSCH collide, the uplink control information in the multi-slot PUCCH is multiplexed on the PUSCH for transmission, or the PUSCH is discarded and only the uplink control information in the multi-slot PUCCH is transmitted, thereby improving communication. The process avoids the multi-slot PUCCH occupying different numbers of RE resources for transmission in different time slots, ensuring that control information and data in the NR system can be transmitted correctly, and optimizing the performance of the NR system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to an information transmission method, a receiving method, a terminal and a network device. Background technique [0002] At present, in the NR (New Radio, new air interface) communication system, the uplink control information HARQ-ACK (Hybrid Automatic Repeat request Acknowledgment, hybrid automatic repeat response response information) and CSI (ChannelState Information, channel state information) are supported in the PUSCH (Physical Uplink Shared Channel, physical uplink shared channel) and data for multiplexing transmission. [0003] At present, NR supports multi-slot PUCCH (Physical Uplink Control Channel, physical uplink control channel) and multi-slot PUSCH transmission. When a single-slot PUCCH and PUSCH collide, the current conclusion is that if in a conflict slot, PUCCH and PUSCH If the start symbol of the PUSCH is the same, the uplink control information i...
