1. An apparatus to be implemented in a user equipment (UE), the apparatus comprising:
a memory to store:
a table that indicates, for respective possible 2-bit values of a field of a received downlink control information (DCI), a respective channel access type and a respective cyclic prefix extension; and
a 2-bit value of the field of a received DCI; and
processor circuitry coupled to the memory, the processor circuitry to:
identify, based on an identification that the UE is to operate in accordance with a semistatic channel access mode, the table;
identify, based on the 2-bit value and the table, a channel access type and a cyclic prefix extension; and
encode an uplink channel transmission based on the channel access type and the cyclic prefix extension.
