Wireless device and method of transmitting uplink data and buffer status reports in a wireless communications system

摘要

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.

1. A method for communicating with a base station, the method performed by a user equipment (UE) and comprising:
calculating, by the UE, an amount of first data stored in uplink buffers; and transmitting, by the UE, a buffer status report based on information on the calculated amount of first data to the base station, wherein the first data stored in the uplink buffers comprises at least one packet data convergence protocol (PDCP) service data unit (SDU) and at least one PDCP protocol data unit (PDU), and wherein the at least one PDCP SDU has not been compressed and the at least one PDCP PDU has been compressed using a robust header compression (ROHC) scheme.
