Wireless communication method and apparatus for generating a serving grant based on a received relative grant
Abstract
A wireless communication method and apparatus for generating a scheduling grant based on a relative grant are disclosed. A wireless transmit/receive unit (WTRU) receives an absolute grant from a serving radio link set (RLS) and receives a relative grant from the serving RLS and at least one non-serving radio link (RL). The WTRU decodes enhanced dedicated channel (E-DCH) absolute grant channel (E-AGCH) signals to detect an absolute grant, and decodes E-DCH relative grant channel (E-RGCH) signals to detect at least one relative grant. The WTRU then calculates a serving grant based on the detected absolute grant and/or the relative grant(s). The relative grant may be detected by performing a hypothesis test on the E-RGCH signals. A multiple alternative hypothesis test is performed for detecting the E-RGCH signals from the serving RLS and a binary hypothesis test is performed for detecting the E-RGCH signals from the at least one non-serving RL.
