Adjusting parameters of a transmission in response to interference
Methods and apparatuses for determining whether to perform transmissions or receptions. A method for a user equipment (UE) to determine whether to perform the transmissions includes receiving a n for a search space set for receptions of physical downlink control channels (PDCCHs) according to a common search space (CSS) and receiving a PDCCH that includes a downlink control information (DCI) format. The method includes determining a set of time resources and a set of frequency resources based on an indication in the DCI format and canceling a transmission of a sounding reference signal (SRS) in time resources from the set of time resources based on determining that the SRS transmission would include frequency resources from the set of frequency resources. The method includes transmitting a physical uplink control channel in time resources from the set of time resources and in frequency resources from the set of frequency resources.
