1. A wireless terminal comprising:
processor circuitry configured to:
select an index from among a plurality of indices included in a buffer status table according to uplink data stored in a buffer, each index of the plurality of indices having a corresponding integer index value, the correspondence of each integer index value is to each index of the plurality of indices in an order of the plurality of indices and
transmit a buffer status report including the index,
wherein the plurality of indices in the buffer status table include at least a first index, a second index, and a plurality of third indices, the first index indicating a 0 byte as a buffer size, the second index indicating Reserve as a buffer size, the plurality of third indices being indices of the plurality of indices other than the first index and the second index, the plurality of third indices indicating as buffer sizes a plurality of values, respectively, that increase exponentially with an increase of the corresponding index value of the corresponding third index.
