Cell search procedure for heterogeneous networks
In a heterogeneous network, low power cells are detected by correlating a first and second signal originating from an unknown cell, such as synchronization signals, e.g., SSS received in a first and second time period (e.g., subframes 0 and of a frame with corresponding sets of possible SSS signals....

Summary: | In a heterogeneous network, low power cells are detected by correlating a first and second signal originating from an unknown cell, such as synchronization signals, e.g., SSS received in a first and second time period (e.g., subframes 0 and of a frame with corresponding sets of possible SSS signals. The cell identities for the candidate cells can be used to determine corresponding reference symbol sequences for the candidate cells. The final determination of the cell identity is then made by correlating a third signal originating from the unknown cell, such as a reference signal received in a third time period (e.g., an almost blank subframe or a broadcastsubframe)with the set of reference signalsfor the candidate cells. The correct cell identity is determined to be the cell identity yielding the greatest correlation with its corresponding reference signal. |
