Method and Apparatus for Performing Buffer Status Reporting
First Claim
1. A method for performing buffer status reporting in a user equipment of a wireless communication system comprising:
- forming a medium access control protocol data unit, abbreviated in MAC PDU hereinafter, comprising a padding field with a size smaller than a first predefined value;
selecting a first logic channel group from a plurality of logic channel groups of the user equipment according to priorities and data amounts of uplink buffers of the plurality of logic channel groups;
carrying information about a data amount of an uplink buffer of the first logic channel group with a short-format buffer status reporting, abbreviated in BSR hereinafter, control element; and
carrying the short-format BSR control element with the padding field of the MAC PDU for a network of the wireless communication system.
