1. A method for transmitting a channel or signal, the method comprising:
receiving first information for a set of downlink reference signals (DL RSs);
identifying second information for first and second thresholds;
determining a first spatial filter corresponding to a first DL RS from the set of DL RSs, wherein:
a first reference signal received power (RSRP) for the first DL RS is larger than the first threshold, and
a first exposure level corresponding to the first spatial filter is smaller than the second threshold; and
transmitting the channel or signal using the first spatial filter, wherein:
the channel is a physical random access channel (PRACH), a physical uplink shared channel (PUSCH), or a physical uplink control channel (PUCCH), or
the signal is a sounding reference signal (SRS).
