11. A method in a first node for wireless communications, comprising:
receiving a first information block, the first information block comprises a MAC CE;
receiving or transmitting a first-type reference signal;
receiving a first signaling, the first signaling comprises DCI; and
operating a first signal;
wherein the first information block is used to determine M first-type indexes out of N first-type indexes, M being a positive integer greater than 1, and N being a positive integer no less than M; the M first-type indexes are used to determine M1 information elements out of N1 information elements, and the M first-type indexes are used to determine M2 information elements out of N2 information elements, M1 and M2 respectively being positive integers greater than 1 and no greater than M, N1 being a positive integer no less than M1, and N2 being a positive integer no less than M2; the N1 information elements and the N2 information elements are respectively TCI states configured for downlink and uplink; any information element of the N1 information elements and the N2 information elements comprises a first-type index and a second-type index set, and each second-type index set comprises one or more second-type indexes, of which each second-type index indicates a reference signal resource; a reference signal resource indicated by any second-type index comprised by any information element of the N1 information elements and the N2 information elements is one of a CSI-RS resource, a CSI-RS resource set, a SRS resource, an SRS resource set or a synchronisation signal/physical broadcast channel block resource; the first signaling comprises scheduling information of the first signal, and the first signaling indicates a first information element; the operating action is receiving or transmitting; when the operating action is receiving, the first signaling indicates the first information element out of the M1 information elements, and a second-type index set comprised by the first information element is used to determine Rx parameters of the first signal; when the operating action is transmitting, the first signaling indicates the first information element out of the M2 information elements, and a second-type index set comprised by the first information element is used to determine Tx parameters of the first signal; the Rx parameters comprise large-scale properties of a channel over which the first signal is conveyed, and the large-scale properties comprise one or more of delay spread, Doppler spread, Doppler shift, average gain, average delay or Spatial Rx parameters; the Tx parameters comprise a spatial domain transmission filter; the first-type reference signal is transmitted in a first-type reference signal resource, and the second-type index set comprised by the first information element indicates the first-type reference signal resource; when the operating action is receiving, the first-type reference signal is used to determine large-scale properties of a wireless channel over which the first signal is conveyed; when the operating action is transmitting, the first-type reference signal is used to determine the Tx parameters of the first signal; the first information block is transmitted on a PDSCH, the first signaling is transmitted on a PDCCH.
