Scheduling request configurations for logical channels in a wireless device
A wireless device receives a first SR configuration corresponding to first logical channel(s); and a second SR configuration corresponding to second logical channel(s). Based on the first logical channel(s) having data available for uplink transmission: a first counter, of the first SR configuration, is set to a first initial value and incremented based on transmission of a first SR associated with the first logical channel(s); and a random access preamble is transmitted in response to the first counter reaching a first counter value. Based on the second logical channel(s) having data available for uplink transmission: a second counter, of the second SR configuration, is set to a second initial value and incremented based on transmission of a second SR associated with the at least one second logical channel; and a random access preamble is transmitted in response to the second counter reaching a second counter value.
