发明名称 Efficient spectrum utilization with almost blank subframes
摘要 Systems and methods for providing efficient utilization of spectrum in a cellular communication network that applies Almost Blank Subframes (ABSs) are disclosed. In general, the network includes an access node that applies ABSs in the downlink. In one embodiment, the access node identifies UEs for which transmissions are to be scheduled for the uplink using a scheduling scheme that does not require control information for every subframe. The access node then time-aligns scheduling instants of the UEs and subframes in the uplink that correspond to at least some of the ABSs in the downlink. In another embodiment, the access node identifies UEs for which transmissions are to be scheduled for the downlink using a scheduling scheme that does not require control information for every subframe. The access node then time-aligns scheduling instants of the UEs for the downlink and at least a subset of the ABSs in the downlink.

主权项 1. A method of operation of an access node in a cellular communication network, comprising: applying almost blank subframes in a downlink from the access node; identifying one or more user equipment devices for which transmissions are to be scheduled using a scheduling scheme that does not require control information for every subframe scheduled by the scheduling scheme; and time-aligning scheduling instants of the one or more user equipment devices and subframes that correspond to at least some of the almost blank subframes in the downlink.
