A wireless transmit receive unit (WTRU) may receive physical uplink control channel (PUCCH) configuration information, SBFD configuration information, and DCI comprising a first PRI. The WTRU may determine that a PUCCH transmission is to be sent. The WTRU may determine, based on a first rule of interpreting the first PRI and the PUCCH configuration information, that a first PUCCH resource indicated by the first PRI is included in at least one frequency resource that is at least partially included in at least one subband for uplink (UL) transmission and one subband for downlink reception indicated by the SBFD configuration information. The WTRU may determine a second PUCCH resource, which may be determined based on a second rule for interpreting the first PRI and the PUCCH configuration information. The second PUCCH resource may be within subbands for UL transmission. The WTRU may transmit the PUCCH transmission using the second frequency resource.
