Claim of US Patent No. 10,993,251

1. A method of a UE (User Equipment), comprising:the UE receives a grant on a first interface wherein the grant indicates a first resource for transmission of a first scheduling information, a second resource for transmission of a second scheduling information, and a time and frequency resource for a data transmission in a resource pool on a second interface;
the UE transmits the first scheduling information in the first resource indicated by the grant on the second interface in a first timing interval;
the UE transmits the second scheduling information in the second resource indicated by the grant on the second interface in a second timing interval; and
the UE transmits the data transmission in the time and frequency resource indicated by the grant on the second interface in a third timing interval,
wherein a timing difference between the second timing interval in which the second scheduling information is transmitted in the second resource indicated by the grant and the first timing interval in which the first scheduling information is transmitted in the first resource indicated by the grant is indicated by the grant, wherein the second scheduling information is different than the first scheduling information,
wherein the first scheduling information indicates a first timing offset between transmission of the first scheduling information in the first timing interval and transmission of the data transmission in the third timing interval, and the second scheduling information indicates a second timing offset between transmission of the second scheduling information in the second timing interval and transmission of the data transmission in the third timing interval, and the first timing offset is different from the second timing offset,
wherein the first timing interval is a first TTI (Transmission Time Interval),
wherein the second timing interval is a second TTI, and
wherein the third timing interval is a third TTI.
