The system may support semi-persistent and non-persistent resource assignments. A semi-persistent resource assignment is valid for as long as more data is sent within a predetermined time period of last sent data and expires if no data is sent within the predetermined time period. A non-persistent resource assignment is valid for a predetermined duration or a specific transmission. A semi-persistent resource assignment may be granted for an expected spurt of data to send via the communication link. For Voice-over-Internet Protocol (VoIP), a semi-persistent resource assignment may be granted for a voice frame in anticipation of a spurt of voice activity, and a non-persistent resource assignment may be granted for a silence descriptor (SID) frame during a period of silence.patentJP5752673US8848618CN101507201BRPI0715663JP2013118654KR101168475AU2007286627NZ574388UA93732RU2413374RU2009110210HK1134181JP2010502127CN101507201KR20090060304EP2062402NO20090534MX2009001823US2008117891WO2008024890TW200818826AU2007286627CA2658839WO20080248903898250740977839
