Method for communicating and radio station therefor

摘要

The present invention relates to method for communicating between a primary station and a secondary station comprising
(a) at the secondary station, upon arrival of a data packet to be transmitted to the primary station, buffering said data packet in a buffer, and transmitting to the primary station a request for an uplink transmission resource if a request condition is satisfied, said request condition being based on at least one previous grant of uplink transmission resource,(b) at the primary station, granting to the secondary station an uplink transmission resource to be used.

主权项

1. A method, executable by a processor within a secondary station for the communication of data and control information with a primary station, said method comprising:
receiving control information from the primary station; and when, at a current time, data is available in a buffer for uplink transmission and a grant of uplink resource for transmission of data is not available to transmit said available data,
determining a time of a most recent, with respect to said current time, previous buffer status report that was made using resources granted by a previous grant of uplink resources,determining a difference between said current time and said time of said most recent previous buffer status report; andtransmitting a request for uplink resources when said difference exceeds a threshold.
