1. A method comprising:
determining a type of handoff-related measurement to perform based on a determined length of a scan interval;
performing first handoff-related measurements of first wireless signals from a first neighbor cell received at first multiple input multiple output (MIMO) antenna resources of a device, wherein the device is in communication with a serving cell; and
performing second handoff-related measurements of second wireless signals from a second neighbor cell received at second MIMO antenna resources of the device, the second wireless signals received at the second MIMO antenna resources concurrently with the first wireless signals being received at the first MIMO antenna resources.
