Abstract: 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.

Abstract: There is provided a method of transmitting an uplink for reference sensitivity test for intra-band non-contiguous CA in LTE-A system. The method may comprise: 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, transmitting an uplink on a primary component carrier using allocated resource blocks (RBs). 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 number of the allocated resource block (RB) in the primary component carrier may be limited to 10 to meet a requirement for a reference sensitivity on a downlink of the secondary component carrier.

Abstract: There is provided a method of reducing transmission power. The method may comprise: receiving a network signal, if a carrier aggregation (CA) is configured and if the configured CA corresponds to an intra-band contiguous CA; applying an additional maximum power reduction (A-MPR) for a transmission, based on the network signal. If a configuration of the CA corresponds to a CA_1C and if the aggregated transmission bandwidth is the summation of 75 RBs and 75 RBs, a value of the A-MPR is specified for L_CRB>10. The L_CRB is a length of a contiguous resource block allocation.
