the first message is configured by a second command, wherein the second command comprises the DCI;
the first message being one type of information in a high layer configuration of the UL signal; or
the first message being one type of information in the TCI state, and the TCI state being one type of information in the high layer configuration of the UL signal.
8. The method of claim 1 , further comprising:
receiving, by the wireless communication device, a predefined parameter that is set to ‘enable’ which indicate to the wireless communication device to obtain the first information of the UL signal according to the TCI state corresponding to the TCI codepoint.
9. The method of claim 1 , wherein the UL signal includes at least one of: a physical uplink control channel (PUCCH), a physical uplink shared channel (PUSCH), an aperiodic sounding reference signal (SRS), a semi-persistent SRS, or a periodic SRS.
10. A wireless communication device, comprising:
at least one processor configured to:
receive an activation command, wherein the activation command activates one or more activated transmission configuration indicator (TCI) states;
determine an activated TCI state from the one or more activated TCI states, wherein the activated TCI state is applicable to a downlink (DL) signal and corresponds to a codepoint of a TCI field of a downlink control information (DCI) and the codepoint is determined according to the DCI, wherein the activated TCI state is applicable to the DL signal responsive to the activated TCI state including one or more reference signals (RSs) and corresponding quasi co-location (QCL) type parameters, and the DL signal and each of the one or more reference signals (RSs) satisfying a QCL relationship with respect to the corresponding QCL type parameter;
determine, based at least on the activated TCI state, a first information, wherein the first information includes a beam of an uplink (UL) signal and a power control parameter of the UL signal; and
transmit, via a transmitter, the UL signal according to the first information,
wherein the UL signal includes an aperiodic sounding reference signal (SRS).
11. The wireless communication device of claim 10 , wherein the one or more activated TCI states comprises a reference signal, and wherein the first information is determined according to the reference signal.
12. The wireless communication device of claim 10 , wherein the TCI codepoint is selected according to a first message, wherein at least one of:
the first message is configured by a second command, wherein the second command comprises the DCI;
