  • Patent number: 11558863
    Abstract: 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.

  • Patent number: 11483808
    Abstract: A mobile communication uplink information transmission method and system are provided, to solve a problem that when a terminal device allocates uplink control information and an uplink shared channel on a semi-statically configured physical uplink shared channel, transmission performance of the uplink shared channel is affected by a quantity of resources occupied by the uplink control information. The method is used for a terminal device to send uplink information and a network device to receive uplink information, and the terminal device receives grant-free resource configuration information, and determines a first resource used to allocate a physical uplink shared channel. The terminal device further determines a third resource used to allocate an uplink shared channel. The third resource is a part of the first resource and does not intersect with the second resource, or the second resource is empty. The present invention further provides a system used for the method.
