摘要： A method may include determining a metric for at least one physical resource block of a wireless cellular network in at least a one cell. Each physical resource block may include a set of frequencies, and/or the metric may be based on interference on the at least one physical resource block in the at least one cell. A determination of whether the metric violates a metric threshold may be made, and an overload indicator may be sent to at least one other cell if the metric violates the metric threshold.

摘要： The present invention provides a method for mitigating outages in wireless communication systems using feedback for control channels formed by aggregating groups of resource blocks or resource elements, the method. One embodiment of the method includes generating control channel feedback at user equipment. The control channel feedback is generated using one or more measurements performed on signals received at the user equipment over a downlink control channel at a current aggregation level. The method also includes transmitting the control channel feedback over an uplink channel and using this information for the optimal implementation of Cell range expansion by the network.

摘要： Embodiments of the claimed subject matter provide a method and apparatus for virtual sectorization using an active antenna array. Embodiments of the apparatus include a transmitter for providing signals to an active antenna array. The signals cause the active antenna array to transmit a first reference signal to a first sector indicated to user equipment within the first sector by a sector identifier. The signals also cause the active antenna array to transmit a plurality of second reference signals into a corresponding plurality of second virtual sectors that overlap the first sector. The apparatus also includes a scheduler for scheduling transmission to user equipment based on feedback generated by the user equipment using the first reference signal or the second reference signals.
