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;
wherein a priority of the first logic channel group is higher than priorities of other logic channel groups of the plurality of logic channel groups, and the data amount of the uplink buffer of the first logic channel group is greater than a second predefined value.
