1. A method in a User Equipment (UE) for wireless communication, comprising:
receiving a target radio signal in a first frequency-domain resource;
transmitting a first radio signal;
monitoring a second radio signal in a first time window; and
monitoring a third radio signal in a first time-domain resource in the first frequency-domain resource;
wherein a channel measurement for the target radio signal is used for triggering a transmission of the first radio signal; the target radio signal is a CSI-RS in the first frequency-domain resource, or an antenna port used for transmitting a PDCCH in the first frequency-domain resource is spatially Quasi Co-Located with an antenna port used for transmitting the target radio signal; the second radio signal includes one DCI; the third radio signal is one PDCCH; the first radio signal is used by a target receiver that received the first radio signal for determining a multiantenna related transmission of the third radio signal; the first radio signal is related to a multiantenna related reception of the third radio signal; the first radio signal is used for determining a first antenna port group; an antenna port group used for transmitting the third radio signal is Quasi Co-Located with the first antenna port group; when the second radio signal is correctly received, the second radio signal is used for determining the first time-domain resource, or, the second radio signal is used for determining that the first radio signal is correctly received.
