1. A first node for wireless communications, comprising:
a first receiver, which receives a first information block set; receives a first signaling, the first signaling being Downlink Control Information (DCI), the first signaling comprising a first field, and the first field in the first signaling being used for indicating a first radio resource block, the first field in the first signaling being a PUCCH resource indicator field, the first radio resource block comprising a positive integer number of resource sub-block(s), a number of resource sub-block(s) comprised by the first radio resource block being equal to a number of repetition(s); and receives a first signal, the first signal being transmitted on a PDSCH; and
a first transmitter, which transmits a first bit block in the first radio resource block;
wherein the first signaling is used for indicating scheduling information of the first signal, and the first bit block is used for indicating whether the first signal is correctly received; the first information block set is used for activating a first information element and a second information element from N information elements, with the first information element corresponding to a first index, and the second information element corresponding to a second index, N being a positive integer greater than 1; the first index is different from the second index, and the first index and the second index are both non-negative integers; the first information block set is carried by a MAC CE signaling, and the first information element and the second information element are activated by the same MAC CE for a same PUCCH group;
when the first radio resource block only comprises one resource sub-block, only one information element of the first information element and the second information element is used for determining a spatial relation of the first radio resource block; a second reference information element is one of the first information element and the second information element that corresponds to a smaller value between the first index and the second index, the second reference information element comprises a given reference signal, the given reference signal comprises one of a Channel State Information-Reference Signal (CSI-RS), a Sounding Reference Signal (SRS) or a Synchronization Signal/Physical Broadcast CHannel (SS/PBCH) Block, and the given reference signal is used for determining the spatial relation of the first radio resource block;
when the first radio resource block comprises K resource sub-blocks and K is a positive integer greater than 1, any two resource sub-blocks of the K resource sub-blocks are orthogonal in time domain, the first information element is used for determining a spatial relation of at least one resource sub-block in the first radio resource block, and the second information element is used for determining a spatial relation of at least one resource sub-block in the first radio resource block; a given resource block is any one of the K resource sub-blocks, and a given information element is either the first information element or the second information element; the given information element is used for determining a spatial relation of the given resource block comprises that the given information element comprises a given reference signal, and the given reference signal is used for determining a spatial relation of the given resource block, and the given reference signal comprises one of a CSI-RS, a SRS or a SS/PBCH Block.
