    Abstract: In a general aspect, a monitoring system detects presence of an object in a space, e.g., when no motion is detected. Motion of an object in a space is detected by analyzing a first set of signals based on wireless signals transmitted in a first time period. Lack of motion in the space is detected by analyzing a second set of signals based on wireless signals transmitted in a second, subsequent time period. Whether the object was present in the space during the second time period is detected by analyzing the second set of signals.

    Abstract: A communication device is arranged to operate in a cellular communication system and report Channel State Information, CSI, including a channel quality by a Channel Quality Indicator, CQI, which reports a CQI set. The communication device comprises a receiver arranged to receive antenna-specific reference signals, a channel estimator arranged to evaluate channel conditions from the reference signals to determine values of a CQI set, a reporting processor arranged to determine whether a bounded differential reporting format prevents values of the CQI set to be accurately reported, and to determine a CQI set such that the bounded differential reporting format allows the values of the CQI set to be reported to reduce under-reporting or over-reporting errors that arise from the use of the bounded differential reporting format, and to form a CSI report including the values of the CQI set using the bounded differential reporting format, and a transmitter arranged to send the CSI report. A method and computer program for implementing the method are also disclosed.
