Abstract: User equipment (UE) may indicate a flexible direct current (DC) leakage location signaling capability to a network that facilitates transmission of accurate DC leakage locations to the network for improved reduction of negative impact of DC leakage on signal quality of uplink (UL) allocated resources. The UE may operate in the first DC leakage location signaling mode when only a single component carrier is activated, and indicate to the network one or more DC leakage locations corresponding to the single component carrier. Additionally, the UE may operate in the second DC leakage location signaling mode when at least a portion of two or more component carriers are activated, and enable the network to determine a default DC leakage location associated the two or more component carriers.
