CPC H04W 72/21 (2023.01) [H04L 1/1812 (2013.01)] | 4 Claims |
1. A terminal comprising:
a processor that:
performs a first layer direction mapping that maps first coded bits of a Hybrid Automatic Repeat reQuest-Acknowledgement (HARQ-ACK) to first positions in a layer direction of resource elements of an uplink shared channel;
performs a first frequency direction mapping that changes the first positions to a frequency direction of the resource elements and repeats the first layer direction mapping;
repeats changing the first positions to a time direction of the resource elements and performing the first frequency direction mapping;
determines second positions from among the resource elements available for second coded bit of data, based on the first positions of the mapped first coded bits, to avoid mapping the second coded bit to the first positions of the mapped first coded bits;
performs a second layer direction mapping that maps the second coded bits to second positions in the layer direction;
performs a second frequency direction mapping that repeats changing the second positions to the frequency direction and performing the second layer direction mapping; and
repeats changing the second positions to the time direction and performing the second frequency direction mapping; and
a transmitter that transmits the uplink shared channel.
