Abstract:
An apparatus can receive or transmit parameters for a sounding reference signal (SRS) transmission configuration as an uplink (UL)/downlink (DL) configuration of a serving cell. A time division duplex (TDD) operation with a plurality of component carriers (CCs) can be enabled/generated based on the parameters and at least one component carriers being reserved for the UL transmission or having a higher priority than a physical channel transmission such as a physical uplink shared channel (PUSCH) transmission or a physical uplink control channel (PUCCH) transmission.
