Wireless communication methods and equipment at the first user device and network entity

Abstract

The invention relates to a method and apparatus for wireless communication at first-user and network-enhanced devices. Specifically, the term refers to cross-carrier scheduling of carrier aggregation techniques, and includes methods and equipment for determining the component carrier (CC) index for at least one of the first sub-link transmissions with the second UE and the U transmission with the network entity, the CC index indicating one or more CC values ​​that occur in at least one of the first sub-link transmissions and the U transmission; and communicate at least one of the first sub-link transmissions from the second UE and the U transmission to the network entity based on the cc key.
