METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING WIRELESS SIGNAL IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a wireless communication system, and particularly to a method and device for same, the method including the steps of: receiving, from a base station, L1 information about M number of UCells (M≤N) on which downlink resources are temporarily configured, wherein M number of UCells (M≤N) are a subset of N number of UCells; selectively aggregating K number of UCells (K < M) from among N number of UCells depending on a terminal's cell aggregation capability; and communicating with the base station by using the aggregated K number of UCells.
