Abstract: Methods and apparatus, including computer program products, are provided for QoE/QoS management. In some example embodiments, there may be provided a method. The method may include detecting, by an enforcement point, an initiation of a session of an application; determining, by the enforcement point, whether a new subservice flow needs to be established to enable, for the initiated session, a quality of service differentiation and/or a quality of experience differentiation; sending, by the enforcement point, an indication to a radio to enable the radio to establish a radio buffer to handle the new subservice flow, when the new subservice flow needs to be established; sending, by the enforcement point, parameter information to the radio to enable the radio to configure at least one service parameter of the radio buffer; and forwarding, by the enforcement point, user-plane data associated with the session to the radio including a subservice flow identifier. Related apparatus, systems, methods, and articles are also described.

Abstract: Various communication systems may benefit from efficient communication. For example, various wireless systems may benefit from appropriate handling of user equipment identifiers over a PC5 interface in a PCS-based user equipment to network relay. A method can include assigning to a user equipment an identifier. The identifier can be configured to avoid a layer one identifier collision between the user equipment and other nearby user equipment.

Abstract: A technique includes receiving, by a user device from a base station, information indicating that support for a receive limited user device is enabled based on a presence of a threshold number of receive limited user devices within a range of a cell of the base station, wherein a receive limited user device is unable to receive a transmission that was transmitted based on one or more communication capabilities of a full set of communication capabilities, selecting, by the user device in response to the receiving, one or more communication capabilities to support a receive limited user device, and transmitting, by the user device, information using the selected one or more communication capabilities.

Abstract: The use of PUCCH resources can be more efficient such as by sharing PUCCH resources between URLLC UEs and non-URLLC UEs in a controllable way enhanced with a smart deterministic downlink polling when needed. A method comprises receiving, by a user equipment from a network node of a communication network, information comprising a given physical uplink control channel resource instance allocated to the user equipment, wherein the physical uplink control channel resource instance is allocated to more than one user equipment including the user equipment; signaling the network node using an allocated physical uplink control channel resource instance in a given sub-frame; and, receiving polling form the network node, wherein the polling comprises an uplink grant.

Abstract: Systems, methods, apparatuses, and computer program products for fair resource sharing among user(s) or user groups in broadcast based D2D communications are provided. One method includes monitoring, by a cluster head, at least one user group sharing physical channel resources. The at least one user group may include at least one D2D user equipment. The method may further include calculating a current share of the physical channel resources for the at least one user group based on pre-configured fair sharing rules, determining when a maximum fair share of the physical channel resources are allocated to one of the at least one user group, determining whether remaining physical resources are sufficient. When the remaining physical resources are sufficient, the method may include issuing an indication to the one of the at least one user group. When the remaining physical resources are not sufficient, the method may include issuing a warning to the one of the at least one user group.
