Patent number: 11558863Abstract: The present application discloses a method for multiplexing multi-service UCI on an uplink data channel to solve the problem of different numbers of coded bits of UCI of different services. The method includes: regulating a value of a code rate offset of UCI relative to a UL-SCH, and calculating the number of modulation symbols for transmitting coded information according to the code rate offset. With the consideration that URLLC data requires higher reliability when UCI of the eMBB service is multiplexed on a UL-SCH of the URLLC service, a corresponding numerical value is required to be smaller than 1. When UCI of a URLLC is multiplexed on a PUSCH of the eMBB, the code rate offset is increased. furthermore, high-layer signaling may include a scaling parameter. It is suitable to apply the method disclosed by the present application to different service multiplexing scenarios simultaneously.Type: GrantFiled: December 5, 2020Date of Patent: January 17, 2023Assignee: CHINA ACADEMY OF INFORMATION AND COMMUNICATIONSInventors: Zhiqin Wang, Huiying Jiao, Ying Du, Guiming Wei, Fei Xu, Xia Shen, Zhiyu Yan, Xiaofeng Liu
