Abstract
The method provides buffer status reporting for the transmission of uplink data from a wireless device to a base station. Uncompressed data is stored in a first buffer of the wireless device. A buffer status report is transmitted from the wireless device to the base station, where the buffer status report contains information indicating an amount of the uncompressed data to be transmitted from the wireless device. The information is dependent on the amount of the uncompressed data stored in the first buffer.
Claims20
A wireless device for communication with a base station, the wireless device comprising:
- a first buffer configured to store uncompressed data;
- a second buffer configured to store compressed data;
- a packet data convergence protocol (PDCP) layer employing a robust header compression (ROHC) scheme to compress the uncompressed data;
- and
- a medium access control (MAC) layer configured to transmit a buffer status report to the base station, the buffer status report comprising information indicating an amount of the uncompressed data stored in the first buffer to be transmitted from the wireless device and an amount of the compressed data stored in the second buffer to be transmitted from the wireless device, wherein the uncompressed data comprises at least one PDCP service data unit (SDU).
A method for communicating with a base station, the method comprising:
- storing uncompressed data in a first buffer;
- storing compressed data in a second buffer;
- compressing the uncompressed data by a packet data convergence protocol (PDCP) layer employing a robust header compression (ROHC) scheme;
- and
- transmitting a buffer status report from a wireless device to the base station by a medium access control (MAC) layer, the buffer status report comprising information indicating an amount of the uncompressed data stored in the first buffer to be transmitted from the wireless device and an amount of the compressed data stored in the second buffer to be transmitted from the wireless device, wherein the uncompressed data comprises at least one PDCP service data unit (SDU).
