1. A method for wireless communication at a user equipment (UE), comprising:
receiving, from a base station, configuration information for a control channel search space set in a first transmission time interval (TTI), the received configuration information comprising an indication of an absence of a physical downlink control channel (PDCCH) transmission in the control channel search space set, and a set of time and frequency resources for the control channel search space set;
identifying time and frequency resources allocated for a physical downlink shared channel (PDSCH) in a second TTI based at least in part on the set of time and frequency resources for the control channel search space set in the first TTI and the indication of the absence of a PDCCH transmission in the control channel search space set;
receiving, in a field of a downlink control information (DCI), a first transmission configuration indication (TCI) state; and
receiving, based at least in part on a scheduling offset of a PDSCH transmission indicated by the DCI being less than or equal to a threshold value, the PDSCH transmission in the second TTI using the identified time and frequency resources using a first beam associated with a second TCI state, the first beam different from a second beam associated with the first TCI state, and the second TCI state of a control resource set associated with the control channel search space set.
