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: Systems and method provide for cell reconfirmation methods for a multi-Radio Access Technology (RAT) capable User Equipment (UE). A method for performing a cell reconfirmation method by a multi-Radio Access Technology (RAT) capable User Equipment (UE), the method includes: performing, by the UE, cell reconfirmation using information derived from a Normal Burst (NB) of a transmitted Global System for Mobile communication (GSM) radio signal, wherein the cell reconfirmation verifies an identity of a GSM cell associated with the transmitted GSM radio signal. The method can further include: operating the multi-RAT capable UE in a serving cell of a first RAT; and selecting the cell reconfirmation method to reconfirm a Global System for Mobile (GSM) communication neighbor cell located in a second RAT which is a GSM RAT, wherein a first cell reconfirmation method uses a received Normal Burst (NB) and a second cell reconfirmation method uses a received Synchronization Burst (SB).

Abstract: A wireless communication apparatus is arranged to detect, among a plurality of modulated carrier signals of different frequencies, at least one of the modulated carrier signals modulated with a tone burst. A receiver provides a composite signal comprising the plurality of modulated carrier signals received simultaneously. An ADC generates samples of the composite signal, and the samples of the composite signal are divided into a plurality of blocks. The samples of each block are transformed into frequency domain components, and the frequency domain components of each block are divided into a plurality of groups, each group corresponding to a range of frequencies occupied by a different one of the modulated carrier signals. Tone burst detection is performed on each group, and it is determined which of the modulated carrier signals is modulated with the tone burst, according to which of the groups the tone burst is detected in.
