Methods of Conveying Buffer Status with Mixed Critical and Non-Critical Traffic

A method performed by a wireless device, the method comprising:

• prioritizing-transmission of data associated with a first logical channel according to a first priority associated with the first logical channel;
• determining that the wireless device has data to transmit on at least one second logical channel of a priority N that is less than the first priority, the second logical channel being associated with at least one logical channel group C;
• generating a buffer status report of type N, BSR N, for the second logical channel;
• starting a timer when the BSR N is generated, and in response to an expiration of the timer before transmission of the BSR N;
• prioritizing a transmission of the BSR N for the at least one second logical channel over a data transmission for the first logical channel.

A wireless device comprising:

• processing circuitry configured to:
• prioritizing transmission of data associated with a first logical channel according to a first priority associated with the first logical channel;
• determine that the wireless device has data to transmit on at least one logical channel of a priority N, that is less than the first priority, the logical channel being associated with at least one logical channel group;
• generate a buffer status report of type N, BSR N, for the at least one second logical channel of the priority N;
• and
• starting a timer when the BSR N is generated, and in response to an expiration of the timer before transmission of the BSR N;
• prioritize a transmission of the BSR N for the at least one second logical channel over a data transmission for the first logical channel.
