Abstract: A method may include initiating, by a transmitter user equipment, a hybrid automatic repeat request process for groupcasting a transport block over seedbank to one or more relay user equipment and at least one remote user equipment. The method may also include performing a first groupcast transmission of the transport block using the hybrid repeat request process. The method may further include monitoring feedback from the one or more relay user equipment and the at least one remote user equipment at a first time instance and at a second time instance. In addition, the method may include generating a retransmission strategy of the transport block depending on the feedback monitored at the first time instance and the second time instance. Further, the method may include controlling retransmission of the transport block using the hybrid automatic repeat request process based on the retransmission strategy.

Abstract: Various example embodiments relate to providing feedback with an adaptive acknowledgement mode. A device may transmit an allocation of transmission resource(s) associated with a second acknowledgement mode. The second acknowledgement mode may include transmission of a positive acknowledgement and a negative acknowledgement. Another device may detect a condition to switch to a first acknowledgement mode including transmission of the negative acknowledgement and not transmission of the positive acknowledgement. The other device may transmit an indication of a switch to the first acknowledgement mode. Apparatuses, methods, and computer programs are disclosed.

Abstract: An ARQ system for sidelink communication between transmitter and receiver, with the help of cooperative UE, or relay UE is disclosed. The relay intercepts the initial transmission from transmitter to receiver. If the relay does not intercept any ARQ feedback from the receiver (DTX), it retransmits the initial transmission. Upon receiving at least the Sidelink Control Information, SCI, identifying the retransmission, the transmitter terminates the HARQ process, assuming that the relay is now in charge of the retransmission. Upon reception of the retransmission, the receiver feeds back an HARQ ACK to the relay and the transmitter. If the receiver correctly receives the initial transmission, it feeds back an HARQ ACK to the relay and the transmitter and both relay and transmitter stop the HARQ process. If the relay does not successfully receive the initial transmission, it feds back a NACK to the transmitter which performs retransmission to the relay.

Abstract: Systems, methods, apparatuses, and computer program products for configuring a dual-mode SL LCH with simultaneous mode 1 and mode 2 transmission are provided. One method may include configuring one or more dual-mode sidelink (SL) logical channels (LCHs) to at least one user equipment to enable simultaneous sidelink mode 1 and sidelink mode 2 transmission. The method may also include receiving, from the at least one user equipment, at least one sidelink (SL) buffer status report (BSR) that may optionally comprise buffer status for one or more of the configured dual-mode logical channels (LCHs) according to a network configuration, and transmitting, to the at least one user equipment, a resource allocation that can be applied for the dual-mode logical channels (LCHs) according to the network configuration.

Abstract: The present invention provides apparatuses, methods, systems, computer programs, computer program products and computer-readable media for reducing overhead for Quality-of-service (QoS) monitoring of vehicle-to-everything (V2X) services. The method comprises receiving, at a user equipment, from a serving network, a request for a Quality-of-Service (QoS) monitoring session, making a first determination, at the user equipment, whether the user equipment is relevant for the request, based on the content of the request, making a second determination, at the user equipment, if it is determined in the first determination that the user equipment is relevant, whether the request is received in dedicated signaling or common signaling, deciding, at the user equipment, whether or not to initiate the requested QoS monitoring session based on the second determination.
