Method for radio resources usage reporting in a LTE network and uses thereof for interference reduction and for energy optimization

摘要

The method comprises a LTE cellular base station reporting radio resources usage information about its resource assignment in a current LTE frame emitted or to be emitted thereby, regarding slot usage for at least the slots of the downlink subframes of the current LTE frame, and generally also regarding the slots of subsequent downlink subframes and of also regarding uplink subframes. The uses of the method are for interference reduction and for energy optimization.

1. A method for radio resources usage reporting in a LTE network, the method comprising:
a LTE cellular base station reporting radio resources usage information regarding resource assignment of the LTE cellular base station in a current LTE frame emitted or to be emitted thereby, said radio resources usage reporting regarding slot usage being performed for at least slots of downlink subframes of the current LTE frame, wherein said radio resources usage reporting is further performed for slots of uplink subframes of the current LTE frame indicating if an uplink subframe is almost blank or used, and by including usage information within at least one subframe of the current LTE frame itself, wherein said usage information is at least included in a first slot of every subframe of the current LTE frame, further comprising including said usage information in a PHICH of every subframe of the current LTE frame, wherein said usage information is included in a Slot Indicator which uses a different coding than a coding used for a HARQ Indicator, and wherein said Slot Indicator is a Slot Indicator PHICH group containing two slot indicator PHICH processes, separated by standard orthogonal sequences, one for slot occupation in a downlink and another for subframe occupation in an uplink.
