METHOD AND DEVICE FOR IMPLEMENTING A DURATION DURATION TIMER OF DATA FOR TRANSMISSION BY ENHANCED DEDICATED CHANNEL

摘要

method and device for implementing an enhanced dedicated channel transmission data lifetime timer. A wireless communication system, which supports enhanced dedicated channel (e-dch) data transmission, includes a wireless transmission and reception unit (wtru), and at least one b-node and a radio network controller. (rnc). wtru includes a buffer, a data lifetime timer, a retransmission counter, a process, and a hybrid-automatic repetitive request controller (h-arq). The timer sets a lifetime for at least one of the data blocks, which are stored in the buffer. If no physical resource allocation has occurred for the data block that is associated with the lifetime timer and is nearing its end, then wtru sends an urgent request to the channel allocation. If physical resources have not been allocated, the data block has its priority increased for data transmission over the other data blocks. the data block is discarded if the lifetime timer expires or if wtru receives feedback information indicating that the data block was successfully received by node-b.
