Information transmission method and device

Abstract

The invention provides an information transmission method and device. The method comprises the following steps: obtaining a first uplink channel, and enabling the first uplink channel to bear the joint information of second uplink control information and third uplink control information; and when a third uplink channel and the first uplink channel satisfy the first condition, sending the joint information in the first uplink channel. When the third uplink channel and the first uplink channel do not meet the first condition, sending the third uplink control information in the third uplink channel; wherein the first condition comprises that the distance between the end symbol of the first uplink channel and the end symbol of the third uplink channel is less than or equal to a first threshold; the distance between the start symbol of the first uplink channel and the start symbol of the third uplink channel is less than or equal to a second threshold; the difference between the coding rateof the first uplink channel and the coding rate of the third uplink channel is less than or equal to a third threshold. According to the method provided by the invention, the reliability of data transmission of the high-priority service can be ensured.

Description

technical field [0001] The present application relates to the field of communications, and more specifically, to a method and device for information transmission. Background technique [0002] The fifth generation (5G) mobile communication system is committed to supporting higher system performance, supporting multiple service types, different deployment scenarios, and a wider spectrum range. Among them, various service types include enhanced mobile broadband (eMBB), massive machine type communication (mMTC), ultra-reliable and low-latency communications (URLLC), multimedia broadcasting broadcasting service (multimedia broadcast multicast service, MBMS) and positioning service, etc. Different deployment scenarios include indoor hotspot (Indoor hotspot), dense urban area (Dense Urban), suburban area, urban macro coverage (Urban Macro), and high-speed rail scenarios. A wider spectrum range means that 5G will support a spectrum range up to 100GHz, which includes both the low-...

Problems solved by technology

In particular, NR supports UCI joint transmission (multiplexing). When multiple physical uplink control channels (PUCCH) carrying different types of UCI overlap in time domain, the terminal device will combine multiple different types of UCI After encoding, it is transmitted on a PUCCH or a physical uplink shared channel (PUSCH), which causes the transmission delay or reliability of URLLC UCI to be unguaranteed, seriously affecting communication efficiency and user experience
