METHOD AND DEVICE FOR PROVIDING PREVENTION OF DEPLETION OF THE RISING COMMUNICATION LINES IN THE LONG-TERM DEVELOPMENT SYSTEM

摘要

1. A method of prioritizing uplink data from a wireless transceiver unit (WTRU), the method comprising the steps! determining the amount of data for uplink transmission awaiting a buffer in the WTRU; ! determining a set of logical channels and a current buffer state that is associated with each of the logical channels based on at least one of a priority level, a bit rate, a bucket size, and a delay associated with a transmission time interval (TTI); ! transmitting a buffer status message that includes a permission request based on determining the amount of pending data and the set of logical channels; and! receiving permission for subsequent transmission of pending uplink data in response to transmitting a buffer status message. ! 2. The method according to claim 1, additionally containing steps! for each logical channel! determining the status of the buffer; ! determining whether an existing buffer state exceeds a predetermined threshold value or not; ! provided that the available buffer state exceeds a predetermined threshold, transmitting at least one packet of pending data; and! setting the current buffer state equal to the existing buffer state, reduced by the size of at least one packet of transmitted pending data. ! 3. The method according to claim 2, in which the current buffer state for each logical channel may take a negative value. ! 4. The method according to claim 1, in which the message on the status of the buffer is transmitted over the uplink channel allocated in the previous resolution
