The invention discloses a wireless transmission and reception unit (WTRU) configured for transmitting transmission time interval (TTI) binding. The TTI binding is conflicted with a measuring interval and the WTRU is configured to: construct the TTI binding including a plurality of subframes, determine at least one of the plurality of subframes in confliction with the measuring interval and determine the first subframe in the plurality of subframes failing to conflict with the measuring interval, associate the first subframe in the plurality of subframes failing to conflict with the measuring interval with a first redundancy version (RV), and transmit the first subframe in the plurality of subframes associated with the first redundancy version.
