Abstract

To test whether a first radio channel is synchronized, a first quality value (e.g., power control bits) is determined for a first radio channel (e.g., DPCCH or F-DPCH), and a second quality value is determined for a second radio channel (e.g., PCICH) which carries pre-coding information, PCI, (e.g. beam-forming weights) 302; then the first and second quality values are combined 304 to test whether the first radio channel is synchronised. In specific embodiments the combining includes comparing the first and second quality values against respective first and second thresholds to obtain respective first and second binary results that are logically combined (figure 1); or by multiplying the first and second quality values by respective first and second weighting values to achieve weighted values which are added (figure 2). Radio Link (RL) failure detection.
