Stable Service Quality (QoS) / Quality of Experience (QoE)

Abstract

A wireless transmit / receive unit (WTRU) may be configured to receive configuration information including a threshold value. The WTRU may receive a first grant. The WTRU may determine, in a transmission transmitted in accordance with the first grant, to prioritize one or more PDUs of the second PDU set over one or more PDUs of the first PDU set based on the remaining delay budget of the second PDU set being less than the remaining delay budget of the first PDU set or based on the remaining delay budget of the second PDU set being less than a threshold value. The WTRU may transmit a transmission in accordance with the first grant that includes at least one of the one or more PDUs of the second PDU set. The transmission may include information indicating that the second PDU set is prioritized over the first PDU set.

10. The WTRU of claim 1, wherein the first PDU set is associated with a first priority and a first payload size, and the second PDU set is associated with a second priority and a second payload size, and the indication includes the first payload size or the second payload size.

11. A method performed by a wireless transceiver unit (WTRU), Receiving configuration information including thresholds, Receiving the first grant, In a transmission transmitted in accordance with the first grant, the decision to prioritize one or more PDUs from a second set of protocol data units (PDUs) over one or more PDUs from a first set of PDUs, wherein the decision to prioritize one or more PDUs from the second set of PDUs is based on the remaining delay budget of the second set of PDUs being less than the remaining delay budget of the first set of PDUs, or on the remaining delay budget of the second set of PDUs being less than the threshold, Sending a transmission in accordance with the first grant, which includes at least one of one or more PDUs from the second PDU set, wherein the transmission includes information indicating that the second PDU set takes precedence over the first PDU set. A method that includes this.

12. The method of claim 11, wherein the first grant is a first dynamic grant or a first set grant.

13. The method of claim 11, wherein the information indicating that the second PDU set takes precedence over the first PDU set is transmitted in an uplink control information (UCI) indication, the UCI indication includes information indicating the remaining PDUs of the first PDU set and the remaining time associated with the first PDU set, and information indicating the remaining PDUs of the second PDU set and the remaining time associated with the second PDU set.

14. The method of claim 11, wherein information indicating that the second PDU set takes precedence over the first PDU set is transmitted in a scheduling request (SR), buffer status report (BSR), or delayed status report (DSR).

15. The method of claim 11, further comprising receiving a second grant.

16. The method of claim 11, wherein one or more PDUs of the first PDU set are received before one or more PDUs of the second PDU set are received from the application layer.
