Abstract: Systems, methods, and instrumentalities are disclosed to schedule user equipment (UE) measurements. An HeNB may identify a first cluster of UEs and a second cluster of UEs. The HeNB may determine a measuring gap schedule relating to the first cluster of UEs and the second cluster of UEs. The measuring gap schedule may indicate a measurement time for each cluster. The measurement time may indicate that UEs in a cluster withhold a transmission during the measurement time. The UEs in the cluster may measure a spectrum (e.g., frequency, channel, etc.) associated with a supplementary cell during the measurement time. The HeNB may send the measuring gap schedule to the first cluster of UEs and the second cluster of UEs. The HeNB may receive spectrum measurements of the supplementary cell from the first cluster of UEs and the second cluster of UEs, e.g., in accordance with the measuring gap schedule.

The LE supplementary cell may be an FDD supplementary cell dynamically configurable between an UL only mode, a DL only mode, and a shared mode, to match requested UL and DL traffic ratios. The LE supplementary cell may be a time division duplex (TDD) supplementary cell. The TDD supplementary cell may be dynamically configurable between multiple TDD configurations. A coexistence capability for coordinating operations between the LE supplementary cell with other systems operating in the same channel is provided. Coexistence gaps are provided to measure primary/secondary user usage and permit other systems operating in the LE supplementary cell channel to access the channel.

Abstract: A dynamic spectrum management (DSM) engine may determine the channel quality of one or more channels associated with the DSM engine when packets are not being transmitted over the channels. For example, the DSM engine may trigger a channel quality measurement on a non-primary channel on a condition that a predetermined period of time has lapsed since the last activity associated with the non-primary channel. Channel quality measurement may be triggered via a data sending event on the non-primary channel such as sending a data frame on the non-primary channel. The DSM engine may perform respective quality measurements on multiple channels and store the respective quality values in a database. Time-averaged channel qualities for the channels may be computed based on the stored quality values for computing transmit power distribution of across the channels.
