無線通信システムにおける無線リンクの問題及び回復を検知するための技術

Document Type and Number:

Japanese Patent JP5420674

Kind Code:

B2

Abstract:

A technique (300) for radio link detection in a wireless communication system includes estimating a first error rate of an indicator channel (304). In this case, the indicator channel includes an indication of a number of symbols in a control channel. A second error rate of the control channel is also estimated (306). The first and second error rates are then combined to provide a performance metric (308). Based on the performance metric, a determination is made as to whether a radio link problem exists (310).
