Abstract

With respect to generating and sending a MAC PDU by using the radio resources allocated to the mobile terminal, the level of priority between the buffer status report (BSR) and the established logical channels are defined such that the data of each logical channel and buffer status report can be more effectively, efficiently and quickly transmitted.

Claims

1. A method of transmitting a Medium Access Control (MAC) Protocol data unit (PDU), the method comprising:

allocating resources to logical channels including an uplink-common control channel (UL-CCCH) and MAC control element (CE) for buffer status report (BSR) based on a logical channel prioritization that the UL-CCCH MAC Service Data Unit (SDU) has higher priority than the MAC CE for BSR,

transmitting the MAC PDU including the UL-CCCH MAC SDU by using the allocated resources.

2. The method of claim 1, wherein the MAC PDU further including the MAC CE for BSR.

3. A user equipment (UE) apparatus for transmitting a Medium Access Control (MAC) Protocol Data Unit (PDU), comprising:

a transmitting device; and

a processor,

wherein the processor is configured to allocate resources to logical channels including an uplink-common control channel (UL-CCCH) and MAC control element (CE) for buffer status report (BSR) based on a logical channel prioritization that the UL-CCCH MAC Service Data Unit (SDU) has higher priority than the MAC CE for BSR and to transmit the MAC PDU including the UL-CCCH MAC SDU by using the allocated resources via the transmitting device.

4. The apparatus of claim 3, wherein the MAC PDU further including the MAC CE for BSR.
