Claim:
1. A radio link monitoring method for a user equipment transitioning between a first reception mode and a second reception mode in a wireless communication system, the method comprising: estimating a radio link condition based on channel conditions measured during a first evaluation period in the first reception mode; transitioning from the first reception mode to the second reception mode; estimating, for a duration to which an evaluation period is applied, a radio link condition based on channel conditions measured during the evaluation period, wherein the evaluation period is applied in the second reception mode during a duration of time occurring directly after the transition occurs; and after the duration of time, estimating a radio link condition based on channel conditions measured during a second evaluation period in the second reception mode, wherein the evaluation period is not less than a minimum of the first evaluation period and the second evaluation period, and wherein the first reception mode is one of a Discontinuous Reception (DRX) mode and a non-DRX mode and the second reception mode is the other of the DRX mode and the non-DRX mode.
