Signaling for cell switching in carrier aggregation

Abstract

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling indicating a first cell associated with transmission and reception and a second cell associated with reception at the UE. The UE may receive control signaling indicating a switching pattern for the first cell and the second cell. The switching pattern may include first time resources allocated for communication via the first cell and second time resources allocated for communication via the second cell. The first time resources may overlap with a first reference signal occasion and the one or more second time resources may overlap with a second reference signal occasion. The UE may communicate via the first cell and via the second cell based on the switching pattern. The communications may include communication of a first and second reference signal during the first and second reference signal occasions, respectively.
