Abstract

Various aspects of the present disclosure relate to devices and methods for wireless communication providing enhanced reporting of Quality of Experience (QoE) measurements while a device is in an inactive state. A user equipment (UE) reports, using small data transmission (SDT) in uplink message(s) a first list of a portion of the QoE measurement report(s) limited to a first allocation of uplink resources for SDT. In response to determining that the buffer contains an unreported portion of the one or more QoE measurement reports, the UE receives a second allocation of uplink resources for SDT and reports, using SDT while at least the transceiver of the UE is in an inactive state in second uplink message(s), a second list of a second portion of the QoE measurement report(s) limited to the second allocation of uplink resources for SDT.

Description

PRIORITY APPLICATION The application claims priority to U.S. Provisional Application No. 63/377,515 filed Sep. 28, 2022, the content of which is fully incorporated herein. TECHNICAL FIELD The present disclosure relates in general to a communication device, and more particularly to communication devices that report quality of experience measurements. BACKGROUND A wireless communications system may include one or multiple network communication devices, including base stations, which may be otherwise known as an eNodeB (eNB), a next-generation NodeB (gNB), or other suitable terminology. Each network communication device, such as a base station, may support wireless communications for one or multiple user communication devices, which may be otherwise known as user equipment (UE), or other suitable terminology. The wireless communications system may support wireless communications with one or multiple user communication devices by utilizing resources of the wireless communication system (e.g., time resources (e.g., symbols, slots, subframes, frames, or the like) or frequency resources (e.g., subcarriers, carriers). Additionally, the wireless communications system may support wireless communications across various radio access technologies including third generation (3G) radio access technology, fourth generation (4G) radio access technology, fifth generation (5G) radio access technology, and other suitable radio access technologies beyond 5G (e.g., sixth generation (6G)). Quality of Experience (QoE) measurement is an important metric for the design and operation of wireless communication systems, especially for video services that have high traffic demands. Bad network performance may significantly affect the user's experience. QoE metrics are often measured at an end device and can conceptually be seen as the remaining quality after the distortion introduced during the preparation of the content and the delivery through the network, until reaching a decoder at the end device. Reporting of QoE by the end device to a network entity that manages QoE is required to identify and mitigate degradation in transmissions that reduce QoE. SUMMARY The present disclosure relates to methods, apparatuses, and systems providing wireless communication with reporting of Quality of Experience (QoE) measurements for multicast broadcast service (MBS) in an inactive state. Small Data Transmission (SDT) is used by a device to enable the device to maintain power consumption efficiencies of remaining in an inactive state with regard to communicating with a network device of a radio access network (RAN). When reporting buffer data size to the network, the device does not include the size of QoE measurement reports in the buffer. Instead, the device is able to control transmission of the QoE reports and avoid the discarding of QoE reports. Some implementations of the method and apparatuses described herein may include a method for wireless communication at a user device. In one or more embodiments, the method includes receiving, via a transceiver of a user device from a network device, one or more control messages. The user device determines that the one or more control messages enable small data transmission using a first allocation of uplink resources while at least the transceiver of the device is in an inactive state. The user device further determines that the one or more control messages enable generation and transmission of QoE measurement reports. In response, the method includes measuring QoE at the user device and storing one or more QoE measurement reports in the buffer. The method includes reporting, using SDT in at least one first uplink message while at least the transceiver of the device is in an inactive state, a first list of a portion of the one or more QoE measurement reports limited to the first allocation of uplink resources for SDT. In response to determining that the buffer contains an unreported portion of the one or more QoE measurement reports, the method may further include receiving a second allocation of uplink resources for SDT. The method may further include reporting, in at least one second uplink message, a second list of a second portion of the one or more QoE measurement reports. The method includes reporting the second list using SDT while at least the transceiver of the device is in an inactive state. The method includes reporting the second list as limited to the second allocation of uplink resources for SDT. Some implementations of the method and apparatuses described herein may include a method for wireless communication at a network device. In one or more embodiments, the method may include transmitting, via a transceiver of a network device to a user device, one or more control messages to enable: (i) SDT using a first allocation and subsequent second allocations of uplink resources for SDT, while at least the transceiver of the user device is in an inactive state; and (ii) generation of QoE meas
