1. A communication device for handling an uplink (UL) transmission with a plurality of sounding reference signals (SRSs), comprising:
at least one storage device; and
at least one processing circuit, coupled to the at least one storage device, wherein the at least one storage device stores instructions, and the at least one processing circuit is configured to execute the instructions of:
receiving a downlink (DL) signal quasi-colocated (QCLed) via a first spatial relation from a plurality of spatial relations, wherein the first spatial relation is associated with a RS from a network;
selecting a SRS corresponding to the RS from the plurality of SRSs;
performing a channel sensing procedure via a second spatial relation associated with the SRS, to obtain a result; and
performing the UL transmission via the second spatial relation to the network according to the result;
wherein the plurality of SRSs are configured by the network, and are corresponding to a plurality of SRS indices (SRIs), respectively;
wherein the first spatial relation and the second spatial relation are the same.
