Abstract: A user device may receive 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. A receive limited user device is a user device that is unable to receive a transmission that was transmitted based on one or more communication capabilities of a full set of communication capabilities. The user device may select, in response to receiving the information, one or more communication capabilities to support a receive limited user device. The user device may transmit information using the selected one or more communication capabilities.

Abstract: Methods, apparatuses, and computer program products are disclosed for implementing recovery from a communication failure. A method includes receiving, by a first user equipment, an indication that a second user equipment has experienced a failure, where the first user equipment and the second user equipment are part of a same device, and where the first user equipment is configured with a first primary reliability group and where the second user equipment is configured with a second primary reliability group; based upon the indication, the first user equipment transmitting to a network equipment a first signal to activate a secondary reliability group for the first user equipment; and receiving, by the first user equipment, a second signal to use the secondary reliability group, where the second signal is at least partially based upon the first signal transmitted from the first user equipment.

Abstract: Systems, methods, apparatuses, and computer program products for new radio (NR) sidelink (SL) hybrid automatic repeat request (HARQ) feedback are provided. One method may include monitoring, by a user equipment in sidelink groupcast configured with two stage hybrid automatic repeat request feedback channels, a first stage hybrid automatic repeat request feedback channel when no physical sidelink control channel and physical sidelink shared channel is received. The method may include sending a discontinuous transmission indicator or hybrid automatic repeat request negative acknowledgement on a second stage hybrid automatic repeat request feedback channel when hybrid automatic repeat request positive acknowledgement/negative acknowledgement is monitored on the first stage hybrid automatic repeat request feedback channel.

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.
