Method and system for automatically updating a neighbor list


A method and system for automatically updating a neighbor list associated with a serving base station is disclosed. The method involves receiving a measurement report from a user equipment (ue) associated with the serving base station, wherein the measurement report comprises at least one relative signal strength measurement between the ue and each of a plurality of neighboring base stations; comparing the at least one relative signal strength measurement between the ue and the plurality of neighboring base stations with a current signal strength between the ue and the serving base station; identifying at least one of the plurality of neighboring base stations having a greater relative signal strength with respect to the ue than the serving base station a predefined number of times based on the comparison; and updating the neighbor list associated with the serving base station with the identified at least one neighboring base stations..

Channel and interference measurement in lte/lte-a networks including unlicensed spectrum


Channel and interference measurement in long term evolution (lte)/lte-advanced (lte-a) networks including unlicensed spectrum is discussed in which a user equipment (ue) detects a reference signal from a serving base station over a carrier of a shared spectrum for measurement. The reference signal may be a channel usage beacon signal (cubs) transmitted by the serving base station prior to transmission or may be a specific channel state information (csi) reference signal transmitted in the first subframe of a transmission frame.

Dynamic management of an on/off status of a base station from a routing proxy


The application relates to the problem that when an henb switches off (henb1-3) while connected via a proxy (pr) as mentioned by release 11 of 3gpp tr 37.803 to a peer x2ap entity, the x2ap entity in the henb can not inform its peer (enb1) that it is no longer reachable. The problem is solved in that when the proxy detects the disconnection of the sctp connection (sct-p1-3) between the henb and itself, it transmits an x2ap stop message to the enb (enb1), whereby this message indicates the end of the sctp connection (sctp1-3) and identifies the henb..
