Description

[0002] The 5th Generation Mobile Communication (5G) system needs to adapt to diversified scenarios and service requirements. The 5G system defines three main application scenarios: Enhanced Mobile Broadband (eMBB), Ultra-reliable and Low Latency Communications (URLLC), and Massive Machine Type Communication (mMTC); these application scenarios put forward requirements of high reliability, low latency, large bandwidth, wide coverage, etc. for the system. For certain User Equipment (UE), multiple different services may be supported, for example, the UE supports both the URLLC service of low latency and high reliability and the eMBB service of large capacity and high rate. In the 5G New Radio (NR) system, due to different channels that can have different starting symbols and lengths, there may be a case of time-domain overlapping of transmission resources; however, when there are multiple overlapping Physical Uplink Control Channel (PUCCH) transmissions on one time slot, the single-carrier property of the UE is destroyed, and different transmission powers cause deterioration of channel estimation performance.

[0003] In the prior art, when Uplink Control Information (UCI) is transmitted on a PUCCH, the UCI transmitted on the same PUCCH has the same priority index and corresponds to one code rate. However, for the scenario of multiplexing UCI of different priority indexes on the same PUCCH and using different code rates for UCI of different priority indexes, how to determine the number of PRBs used for UCI transmission is a problem to be solved.
