The user equipment receives a first bit block, transmits or receives a first wireless signal on a first time-frequency resource set, and transmits a second wireless signal on a second time-frequency resource set. The user equipment determines to transmit the second wireless signal on the second time-frequency resource set. A second bit field in the first bit block is used to indicate the first time-frequency resource set. A first bit field in the first bit block is used to simultaneously indicate a first spatial parameter group for transmitting the first wireless signal and a second spatial parameter group for transmitting the second wireless signal or a first multiple access signature for generating the second wireless signal. The spatial parameter group information used for scheduling PDSCH or PUSCH is applied to the uplink grant-free transmission.

摘要： A conditional level shifter circuit is used to substantially eliminate sneak current from occurring in an integrated circuit device having two or more logic circuit modules in different voltage domains. Sneak current is caused when a signal between the two or more logic circuit modules in different voltage domains is at logic “0” and one of the logic circuit modules is biased at a voltage level above the true ground, VSS, of the integrated circuit device. The conditional ground restoration circuit shifts the virtual ground logic “0” to the true ground level. This eliminates sneak current and logic level corruption.
