Abstract:
1. A wireless communication terminal comprising: a transceiver; a controller coupled to the transceiver, the controller configured to estimate a block error rate for a hypothetical control codeword, the controller configured to determine a first radio link synchronization event when the terminal is in a first mode of operation using a first filter with a first evaluation period based on the estimated block error rate, the controller configured to determine the first radio link synchronization event when the terminal is in a second mode of operation using a second filter with a second evaluation period based on the estimated block error rate, upon transitioning from the first mode of operation to the second mode of operation, the controller configured to use the second filter for determining the first radio link synchronization event while operating in the second mode of operation for a time equal to the second evaluation period of the second filter has elapsed after the start of the transition to the second mode.
