2 Claims

1. A user equipment (UE), characterized by-comprising:

a processor; and

a memory coupled to the processor and storing one or more instructions which, when executed by the processor, cause the UE to:

perform a first downlink control information (DCI) size alignment procedure for a first set of DCI formats, wherein, if at least one of DCI format 3_0 and DCI format 3_1 is configured to be monitored on a cell, the first set of DCI formats includes all DCI formats configured for the cell other than the at least one of DCI format 3_0 and DCI format 3_1; and

perform a second DCI size alignment procedure for the at least one of DCI format 3_0 and DCI format 3_1 if the at least one of DCI format 3_0 and DCI format 3_1 is configured to be monitored on the cell,

wherein

in the second DCI size alignment procedure, the one or more instructions, when executed by the processor, further cause the UE to, if a) both of the DCI format 3_0 and DCI format 3_1 are configured to be monitored on the cell and b) a number of information bits in one of DCI format 3_0 and DCI format 3_1 is less than a payload size of the other one of the DCI format 3_0 and DCI format 3_1, append zeros to the one of DCI format 3_0 and DCI format 3_1 until a payload size equals that of the other one of the DCI format 3_0 and DCI format 3_1, and

in the second DCI size alignment procedure, the one or more instructions, when executed by the processor, further cause the UE to append zeros to the at least one of DCI format 3_0 and DCI format 3_1 until a payload size of the at least one of DCI format 3_0 and DCI format 3_1 equals the smallest size in the first set of DCI formats that is larger than the at least one of DCI format 3_0 and DCI format 3_1.
