The present disclosure relates to a method for managing inter-system interference performed by a network element (800; 900) in a victim cellular communication system (1) comprising a serving cell (3) serving a victim radio device (900A). The method comprises determining that the downlink (DL) reception quality of signals from the serving cell at the victim radio device is below a predetermined first threshold, implying poor DL radio signal quality. The method also comprises determining that the DL signal strength of signals from the serving cell at the victim radio device is above a predetermined second threshold, implying that the poor DL radio signal quality is due to either intra-system interference from DL signaling within said victim system, or to inter-system interference from UL signaling in an aggressor system. If the victim cellular communication system comprises at least one neighboring cell (5), then the method also comprises determining that the DL signal strength of signals from said at least one neighboring cell is below a predetermined third threshold at the victim radio device. The method then comprises determining that the poor DL radio signal quality is due to radio interference from uplink (UL) signaling in an aggressor cell (4) comprised in an aggressor cellular communication system (2).The method also comprises applying interference resolution for mitigating the inter-system interference from the aggressor cell (4).
WO/2015/072904 CODING AND FILTERING FOR MACHINE-TYPE COMMUNICATION||WO||21.05.2015|
||PCT/SE2014/050941||TELEFONAKTIEBOLAGET L M ERICSSON (PUBL)||GATTAMI, Ather|
Encoding and decoding schemes at an encoding device/transmitter and decoder device/receiver, respectively, for use in communicating the state of a system. In an example method carried out by an encoding device, state information x(k), which represents the current state of a monitored system, is measured. The encoding device calculates a state update parameter, based on: a message power constraint P; the covariance N of measurement noise associated with the channel over which encoded state information is to be transmitted; and the norm of the signal vector [s(k), x(k)], where s(k) is a stored state information parameter. The encoding device then calculates a message signal z(k) = G(k)*(x(k) –s(k)), which may then be transmitted to a remote decoder device, and calculates an updated version of the stored information s(k+1) = A*(s(k) + F(k)*z(k)). The encoding device replaces the stored state information s(k) with s(k+1).
