Abstract: The present subject matter discloses a method for antenna activity detection in multi-antenna communication devices. In one embodiment, the method comprises computing a received signal strength indicator (RSSI) value for each of a plurality of antennas based on a sampled data associated with each of the antennas. The RSSI values may then be analyzed to identify an antenna having a highest RSSI value as a primary antenna and one or more antennas having the RSSI value less than the highest RSSI value as auxiliary antennas. Further, an RSSI difference for each of the auxiliary antennas is calculated and compared with a first threshold value to ascertain one or more potentially inactive antennas from among the auxiliary antennas. The potentially inactive antennas may then be further analyzed to identify one or more inactive antennas based at least in part on the RSSI value.

Abstract: An efficient way is described for a user equipment, camping on a cell of a first radio access technology, RAT, to perform measurements on the transmissions from a neighbouring radio cell of a different RAT. Recurrent time gaps that are available for making the measurements are not correlated or synchronized with the recurrent times at which the desired information are transmitted by the transmitter in the second RAT. Therefore, mapping is performed of the time gaps onto the interval at which the desired information is transmitted. The mapping continues until a time interval is covered that ensures that the information in the recurring desired block of information can be obtained. During the mapping of the measurement gaps, only those time intervals that have not already been covered by the mapping are used for obtaining the desired information.
