Abstract

A radio access network node is configured with a relative quality-of-service criterion corresponding to a target traffic flow and a related traffic flow. The node may schedule, for transmission to a user equipment, a packet corresponding to the target flow based on the relative quality-of-service criterion. The quality-of-service criterion may be indicated by core network equipment in an indication that may accompany the packet corresponding to the target flow, which may be a downlink flow. The quality-of-service criterion may be indicated by a user equipment in an indication that may accompany the packet corresponding to the target flow, which may be an uplink flow. The user equipment may receive, from the node, a packet of the target flow via a shareable semi-persistent downlink scheduling occasion resource without waiting for a grant of the resource from the node.

Description

BACKGROUND The ‘New Radio’ (NR) terminology that is associated with fifth generation mobile wireless communication systems (“5G”) refers to technical aspects used in wireless radio access networks (“RAN”) that comprise several quality of service classes (QoS), including ultrareliable and low latency communications (“URLLC”), enhanced mobile broadband (“eMBB”), and massive machine type communication (“mMTC”). The URLLC QoS class is associated with a stringent latency requirement (e.g., low latency or low signal/message delay) and a high reliability of radio performance, while conventional eMBB use cases may be associated with high-capacity wireless communications, which may permit less stringent latency requirements (e.g., higher latency than URLLC) and less reliable radio performance as compared to URLLC. Performance requirements for mMTC may be lower than for eMBB use cases. Some use case applications involving mobile devices or mobile user equipment such as smart phones, wireless tablets, smart watches, and the like, may impose on a given RAN resource loads, or demands, that vary. A RAN node may activate a network energy saving mode to reduce power consumption. SUMMARY The following presents a simplified summary of the disclosed subject matter in order to provide a basic understanding of some of the various embodiments. This summary is not an extensive overview of the various embodiments. It is intended neither to identify key or critical elements of the various embodiments nor to delineate the scope of the various embodiments. Its sole purpose is to present some concepts of the disclosure in a streamlined form as a prelude to the more detailed description that is presented later. In an example embodiment, a method may comprise facilitating, by a radio access network node comprising a processor, receiving a first protocol data unit corresponding to a first traffic flow and facilitating, by the radio access network node, receiving quality information associated with the first protocol data unit, wherein the quality information comprises a related traffic flow indication indicative of a second traffic flow related to the first traffic flow and a relative quality of service indication indicative of a relative quality of service criterion corresponding to the first traffic flow and the second traffic flow The method may further comprise facilitating, by the radio access network node, transmitting, to a user equipment, a second protocol data unit corresponding to the second traffic flow, and facilitating, by the radio access network node, transmitting, to the user equipment, the first protocol data unit according to the relative quality of service criterion. In an embodiment, the quality information may further comprise a first independent quality of service indication indicative of an independent quality of service criterion associated with the first traffic flow. The quality information may further comprise a second independent quality of service indication indicative of the second traffic flow being associated with the independent quality of service criterion. The first protocol data unit may be transmitted according to the independent quality of service criterion, and the second protocol data unit may be transmitted according to the independent quality of service criterion. In an embodiment, the relative quality of service criterion may correspond to at least one of: a latency corresponding to at least one of the first traffic flow or the second traffic flow, a data rate corresponding to at least one of the first traffic flow or the second traffic flow, or a protocol data unit error rate corresponding to at least one of the first traffic flow or the second traffic flow. The method may further comprise prioritizing, by the radio access network node with respect to the independent quality of service criterion, the transmitting of the first traffic flow and the second traffic flow, the prioritizing being performed based on the relative quality of service criterion. Thus, the radio access network node may override the independent quality of service criterion and apply the relative quality of service criterion to transmission of the first traffic flow instead of applying the independent quality of service to transmission of the first traffic flow. In an embodiment, the method may further comprise facilitating, by the radio access network node, receiving a relative quality of service criterion configuration comprising the relative quality of service criterion. The relative quality of service criterion configuration may define the relative quality of service criterion with respect to the independent quality of service criterion. In an embodiment, the method may further comprise prioritizing, by the radio access network node with respect to the relative quality of service criterion, the transmitting of the first traffic flow and the second traffic flow, the prioritizing being performed based on the independent qua
