Japanese Patent JP7247166

B2

Systems, methods, computer-readable medium, and apparatus are disclosed that allow for control information to be provided in an efficient manner during short burst transmission. For example, an apparatus may be configured to receive downlink control information (DCI) that indicates an allocated resource from a base station. The apparatus may also receive data from the base station. The apparatus may generate a cyclically shifted sequence that corresponds to a sequence that is cyclically shifted based on at least one of an ACK or NACK for the received data and a SR. The apparatus may then transmit the cyclically shifted sequence in the allocated resource within one symbol period of a slot of a subframe to the base station. Thus, by transmitting the SR and the ACK/NACK in one symbol, control information for short burst transmissions can be provided in a more temporally efficient manner without adding excessive complexity to the UE.
