Abstract
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.
Claims16
A 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,
- determining whether an uplink grant is available;
- and
- when said uplink grant is determined to be not available;
- 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 and on a time elapsed since a previous transmission of an indication of an amount of data contained in the buffer without receiving a grant for transmission,
- (b) at the primary station, granting to the secondary station an uplink transmission resource to be used.
A secondary station comprising
- means for transmitting data to a primary station on an uplink channel,
- means for buffering data packets to be transmitted to the primary station upon arrival of said data packets,
- means for determining whether an uplink grant is available;
- and
- when said uplink grant is determined to be not available;
- means for requesting an uplink grant if a request condition is satisfied said request condition being based on at least one previous grant of uplink transmission resource and on a time elapsed since a previous transmission of an indication of an amount of data contained in the buffer without receiving a grant for transmission.
A system comprising:
- at least one secondary station comprising:
- means for transmitting data to a primary station on an uplink channel,
- means for buffering data packets to be transmitted to the primary station upon arrival of said data packets,
- means for determining whether an uplink grant is available;
- and
- when said uplink grant is determined to be not available;
- means for requesting an uplink grant if a request condition is satisfied, said request condition being based on at least one previous grant of uplink transmission resource and on a time elapsed since a previous transmission of an indication of an amount of data contained in the buffer without receiving a grant for transmission;
- and
- a primary station, said primary station comprising:
- means for granting to the secondary station an uplink transmission resource.
