Abstract:
Methods and apparatuses are described relating to changes in an antenna configuration of a multi-antenna radio frequency (RF) transceiver between reference signal occasions. In one set of examples, a first antenna configuration at a first reference signal occasion of a first RF transmitter is stored, and if the antenna configuration has changed by the time a second reference signal occasion of the first (same) RF transmitter begins, the antenna configuration is switched back to the first antenna configuration. In another set of examples, compensation data to enable compensation between the first antenna configuration used to measure a first reference signal of a reference RF transmitter and a second antenna configuration used to measure a second reference signal of a neighboring (different) RF transmitter is retrieved and used when computing a time difference between the first and second reference signals.
