Abstract:
1. A method of reselecting a reference channel for performing error rate measurement in a wireless transmit receive unit (WTRU), the method comprising: selecting an initial reference channel from among candidates of transport channels multiplexed on a composite channel, the initial reference channel having a least restrictive block error rate (BLER) requirement; monitoring the initial reference channel to determine its ON or OFF state at a time interval corresponding to a transport time interval (TTI) size of the selected reference channel; determining that the reference channel is in an OFF state in response to detecting activity below a specified level; and in response to determining that the reference channel is in an OFF state, selecting a new reference channel, from among the candidate transport channels, the new reference channel having the least restrictive BLER requirement among the candidate transport channels.
