METHOD AND TERMINAL OF TRANSMITTING AN UPLINK SIGNAL WITH FEWER TRANSMISSION RESOURCE BLOCKS TO PREVENT A LOWERING IN REFERENCE SENSITIVITY IN INTRA-BAND NON-CONTIGUOUS UPLINK CARRIER AGGREGATION

摘要

A method for transmitting an uplink signal by a user terminal includes: transmitting the uplink signal to a base station on a primary component carrier using allocated resource blocks (RBs), if a carrier aggregation (CA) is configured, if the configured CA corresponds to an intra-band CA, and if the configured CA corresponds to non-contiguous CA, wherein if a channel bandwidth by an aggregation of the primary component carrier and a secondary component carrier is at least one of 25 RBs, 50 RBs, 75 RBs and 100 RBs and if a gap between two sub-blocks corresponds to a predetermined range, the allocated resource blocks (RBs) in the primary component carrier is limited to 10 RBs to meet a requirement for a reference sensitivity on a downlink of the secondary component carrier.
