Abstract
The present invention relates to a method for communicating in a network comprising at least one primary station communicating with at least one secondary station, comprising (a) the secondary station sending to the primary station a buffer status report representative of the amount of data in a buffer of the secondary station, (b) in absence of acknowledgement from the primary station, the secondary station retransmitting the buffer status report and, (c) if a maximum number of retransmissions has been reached, the secondary station sending a further buffer status report to the primary station.

A method for operating a secondary station communicating in a network comprising at least one primary station communicating with at least one secondary station, the method comprising:

- sending through a transmitter and an antenna to a primary station a first buffer status report indicating a presence of data in a buffer of the secondary station, the buffer storing data for transmission to the primary station;
- retransmitting through the transmitter and antenna to the primary station, the first buffer status report when a positive acknowledgement from the primary station of receipt of the first buffer status report is not received through a receiver and the antenna from the primary station;
- monitoring by the processor a number of retransmissions to the primary station of the first buffer status report;
- and
- sending to the primary station through the transmitter and antenna a second buffer status report when both:
- a maximum number of retransmissions of the buffer status report has been reached without receiving a positive acknowledgement of receipt of the first buffer status report from the primary station;
- and
- an indication of a resource grant by the primary station for an uplink transmission by the secondary station has not been received through the antenna and receiver within a time window since a last previous transmission of a first buffer status report.
