Abstract
A wireless device receives configuration parameters comprising: first parameters of logical channel(s) indicating that each logical channel of the logical channel(s) is mapped to corresponding first transmission duration(s); and a second parameter indicating a first value for a buffer status report timer. The buffer status report timer is started with the first value in response to: receiving at least one uplink grant associated with a second transmission duration; and at least one logical channel, with data, of the logical channel(s) mapped to the second transmission duration. A buffer status report is transmitted in response to the buffer status report timer expiring.
Claims18
A method comprising:
- receiving by a wireless device and from a base station, one or more parameters comprising:
- first parameters indicating a plurality of duration values for respective transmission durations of each of a plurality of logical channels, wherein each logical channel of the plurality of logical channels corresponds to a respective duration value, and each logical channel of the plurality of logical channels is mapped to one or more transmission durations shorter than or equal to the respective duration value;
- and
- a second parameter indicating a value for a buffer status report timer for the plurality of logical channels;
- receiving at least one uplink grant associated with a second transmission duration;
- starting the buffer status report timer with the value in response to at least one logical channel, with data, of the plurality of logical channels being mapped to the second transmission duration;
- continuing to run the buffer status report timer in response to none of the at least one logical channel, with data, of the plurality of logical channels being mapped to the second transmission duration;
- and
- transmitting a buffer status report in response to the buffer status report timer expiring.
