Abstract
A wireless device receives configuration parameters of logical channel(s) grouped into logical channel group(s) comprising a 1st logical channel group. A padding buffer status report (BSR) is triggered. A truncated BSR is transmitted in in response to: the triggering of the padding BSR; and a number of padding bits being: larger than a size of a short BSR plus a short BSR subheader; and smaller than a size of a long BSR plus a long BSR subheader. The truncated BSR indicates a presence of a buffer size field for the first logical channel group corresponding to a presence bit. The buffer size field indicate an amount of data available across logical channels of the first logical channel group. The truncated BSR comprises: a number of buffer size fields for logical channel groups with logical channels having available data for transmission following a decreasing order of priority.
