Single transmitter switching for dual connectivity

Abstract:

Methods, systems, and devices for wireless communications are described. In some cases, a user equipment (UE) may identify, for a carrier aggregation (CA) configuration including a primary cell and one or more secondary cells, a first frame structure configuration for the primary cell and a second frame structure configuration for a secondary cell of the one or more secondary cells. The UE may receive, from a base station, a downlink communication on the secondary cell. The UE may determine a feedback timing for the secondary cell based on the first frame structure configuration for the primary cell and the second frame structure configuration for the secondary cell. The UE may transmit, in response to the received downlink communication, feedback to the base station according to the feedback timing.
