Claim Text:
1. A method of receiving an allocation of resource blocks (RBs) for an uplink signal, the method performed by a user terminal and comprising: receiving, from a base station via a transceiver of the user terminal adapted to configure a carrier aggregation (CA), a physical downlink control channel (PDCCH) including the allocation of RBs used for the uplink signal; checking, by a processor of the user terminal, a number of the allocated RBs if the configured CA corresponds to an intra-band CA and also corresponds to a non-contiguous CA; and transmitting, via the transceiver, the uplink signal to the base station on a primary component carrier using the allocated RBs, wherein if a channel bandwidth by an aggregation of the primary component carrier and a secondary component carrier is at least one of 50 RBs, 75 RBs or 100 RBs and if a gap between two sub-blocks corresponds to a predetermined range, the checked number of the allocated RBs in the primary component carrier is equal to or less than 10 to meet a requirement for a reference sensitivity on a downlink of the secondary component carrier.
