Certain aspects of the present disclosure relate to methods and apparatus for adaptive antenna switching for measurements, for example, in high gain automotive devices. According to certain aspects, a method is provided herein for wireless communications. The method generally includes selecting, based on one or more conditions, a first measurement configuration that uses at least an external antenna mounted on a surface of a vehicle for one or more measurements or a second measurement configuration that uses at least an internal antenna associated with the vehicle for the one or more measurements; performing the one or more measurements using the selected measurement configuration; and sending a report based on the one or more measurements. The techniques for measurement configuration selection may allow the device to achieve the benefits of both the high gain external antenna and the lower gain internal antenna(s) depending on the current conditions.

Certain aspects of the claimed invention generally relate to a network dynamically configuring one or more cells based on signal quality measurements received from all antennas of a receiver-limited UE. The receiver-limited UE may have a number of receivers that is less than or equal to a number of antennas of the UE. Further, the UE may be capable of operating in a CA mode. Dynamically configuring the one or more cells based, at least in part, on the received signal quality measurements may allow the UE to operate on M&#xd7;N MIMO on the Pcell or Scell.

Mechanism to measure, report, and allocate a highest possible rank for each cell in a carrier aggregation (CA) mode receiver-limited user equipment (UE)

Methods, systems, and devices are described for triggering an antenna switch. A settling time may be identified, and the antenna switch may be delayed based at least in part on the identified settling time. The settling time may include an estimated delay in reception attributable to settling following the antenna switch.
