Abstract
A first process (Step 4) of equalizing the sizes of control information between a first format for a first search space and a second format for a second search space and a second process (Procedure B) of equalizing the sizes of control information between a third format and the first format or the second format are carried out in a stepwise manner.
Claims10
A communication apparatus comprising:
- a receiver, which, in operation, receives one or more signals;
- and
- circuitry, which is coupled to the receiver and which, in operation, monitors, in the one or more signals, a plurality of downlink control information (DCI) formats including a DCI format 0_0, a DCI format 1_0, a first DCI format used for scheduling of physical uplink shared channel (PUSCH), and a second DCI format used for scheduling of physical downlink shared channel (PDSCH), wherein each of the first DCI format and the second DCI format is different from the following DCI formats:
- DCI format 0_0;
- DCI format 0_1;
- DCI format 1_0;
- DCI format 1_1;
- DCI format 2_0;
- DCI format 2_1;
- and
- DCI format 2_2,
- wherein padding or truncation is applied to the plurality of DCI formats according to a procedure including the following steps in order:
- determining the DCI format 0_0 and the DCI format 1_0;
- determining the first DCI format and the second DCI format;
- checking a first condition that a first total number of different DCI sizes of the plurality of the DCI formats is no more than a first determined number, and a second condition that a second total number of different DCI sizes with a cell-radio network temporary identifier (C-RNTI) of the plurality of the DCI formats is no more than a second determined number;
- responsive to both of the first condition and the second condition being met, ending the procedure;
- and
- responsive to at least one of the first condition and the second condition being not met, continuing the procedure including the following additional steps in order:
- adjusting a size of the DCI format 0_0 and a size of the DCI format 1_0;
- checking the first condition and the second condition;
- responsive to both of the first condition and the second condition being met, ending the procedure;
- and
- responsive to at least one of the first condition and the second condition being not met, adjusting a size of the first DCI format based on a size of one of the plurality of DCI formats.
