1. A first node for wireless communications, comprising:
a first receiver, receiving a first information block; and
a first processor, operating first-type information in a first radio resource block;
wherein the first information block is used for determining a first radio resource set and K information units, K being a positive integer greater than 1; the first radio resource block belongs to the first radio resource set; the K information units respectively indicate K spatial relations; a first condition set is used for determining whether a spatial relation corresponding to the operation performed in the first radio resource block is related to the K information units; the first condition set is related to a first parameter, and the first parameter is used for determining whether the first radio resource set corresponds to multiple spatial relations; when the spatial relation corresponding to the operation performed in the first radio resource block is related to the K information units, one or more information units of the K information units are used for determining the spatial relation corresponding to the operation performed in the first radio resource block; the operating is monitoring, or the operating is transmitting; when the operating is monitoring, the first radio resource block comprises at least one PDCCH candidate, and the first-type information comprises DCI; when the operating is transmitting, the first radio resource block is a PUCCH resource, and the first-type information comprises UCI; the first condition set comprises M condition subsets, M being a positive integer greater than 1; when one condition subset in the first condition set is fulfilled, one or more information units of the K information units are used for determining the spatial relation corresponding to the operation performed in the first radio resource block; when none of condition subsets in the first condition set is fulfilled, a first reference signal resource is used for determining the spatial relation corresponding to the operation performed in the first radio resource block, and the first reference signal resource is unrelated to the K information units.
