The base station device of claim 19 or 20, wherein when the target measurement value is greater than the second threshold, no set of reference signals of a first type is transmitted by the base station device in a first time window to trigger transmission of the second wireless signal, wherein the set of reference signals of the first type is used to select P1 antenna port groups from P antenna port groups, wherein P is a positive integer greater than 1, and wherein P1 is a positive integer less than P.
22. The base station device of claim 21, wherein the first transmitter module transmits a first signaling; wherein the first signaling is used to determine the first time window.
23. The base station apparatus of claim 19 or 20, the first transmitter module to transmit a second signaling; wherein the second signaling is used to determine at least one of the first threshold and the second threshold.
24. The base station device of claim 19 or 20, wherein the first transmitter module transmits L sets of reference signals before receiving the second wireless signal; wherein L antenna port groups are used to transmit the L reference signal groups, L being a positive integer greater than 1; when the target measurement is less than or equal to the second threshold, the second wireless signal is used to determine a first antenna port group from the L antenna port groups, the first antenna port group being used to determine multi-antenna related transmissions for the third wireless signal.
