Claim 4:
5. A wireless node in a wireless communication system, the wireless node comprising:
a memory; and
at least one processor coupled to the memory,
wherein the at least one processor is configured to:
generate a buffer size report (BSR) including a first bitmap; and
transmit the BSR to a network,
wherein each bit of the first bitmap indicates whether a corresponding second bitmap is present or not in the BSR,
wherein each bit of at least one second bitmap which is present in the BSR indicates whether buffer size information of a corresponding logical channel group (LCG) is present or not in the BSR,
wherein the at least one processor is configured to set at least one bit of the first bitmap to a first value indicating that the corresponding second bitmap is present in the BSR, when at least one LCG associated with the corresponding second bitmap has data available for transmission.
