ZERO pilot to assess the implementation of interference in a wireless communication system

摘要

1. A method of maintaining the evaluation of interference in a wireless communication network, comprising: determining the resources for transmitting the pilot signal of the zero cell in a cluster of cells; and! transmission zero pilot resources in said cell to allow user terminals (UE) estimate vneklasternye interference comprising interference from cells not belonging to their cluster. ! 2. The method of claim 1, wherein each cell in a cluster of cells is assigned different resources for transmitting the pilot signal of zero. ! 3. The method of claim 1, wherein all cells in the cluster use same resources for transmitting null pilots, and wherein different clusters are assigned different resources for transmitting null pilots. ! 4. The method of claim 1, wherein determining the resources for transmitting the pilot signal of zero comprises determining resources for transmission zero pilot signal based on a feature identifier (ID) or cell cluster. ! 5. The method of claim 1, wherein the transmission zero pilot comprises sending empty transmission resources for transmission on the zero pilot signal by puncturing symbols mapped to the resources. ! 6. The method of claim 1, wherein the transmission zero pilot comprises sending empty transmission resources for transmission on the zero pilot signal by determining the symbols mapped to the resources, and by re-mapping the symbols to other resources. ! 7. The method of claim 1, further comprising: receiving interference information indicative of the vneklasternyh interference observed by UE; and! sending data by the UE, based on the interference information. ! 8. The method of claim 7, further with
