摘要： A method is provided a wireless system for providing small “guard” cells in a heterogeneous network at locations proximate to privately-maintained HeNB (or femto) cells in the heterogeneous network. More particularly, the methodology of the invention addresses the problem of a mobile user in a heterogeneous network located nearby to a privately maintained HeNB cell in the heterogeneous network, and the inherent interference created for the HeNB cell by the necessity of the mobile user having to transmit and receive communications from a distant public macro eNB. By deploying small public “guard” cells in the macro cell proximate to the private HeNB cells, such a public mobile terminal is enabled to communicate with the public small cell at generally lower power than would have been necessary for communication with the distant macro eNB, with a resulting reduction in interference for the nearby HeNB cell. The FL interference between the macro cell and the HeNBs is also mitigated.

摘要： Example embodiments are directed to a method including transmitting, by a small cell, a pilot signal to a user equipment (UE) based on a first training signal received from the UE, and receiving, by the small cell, a second training signal from the UE. The second training signal is offset by a time based on the pilot signal transmitted by the small cell. The time offset represents a difference in time between the UE receiving a reference signal transmitted by a macro cell and the UE receiving the pilot signal transmitted by the small cell. The small cell adjusts a local reference timing based on the second training signal.

摘要： Successfully decoded data received from a mobile terminal as well as the transmission format of that data is relayed over the backhaul from a base station receiver that successfully decoded the mobile terminal's transmission to the base stations in the mobile terminal's active set that presumably were unable to decode the mobile terminal's transmission due to inadequate signal-to-noise ratio. A base station that receives this transmission from the relaying base station that did'successfully decode and demodulate the mobile terminal's transmission is then able to reconstruct the data and subtract it from the total interference, thereby increasing the signal-to-noise ratio at this base station for its in-cell processing.
