Abstract: An apparatus includes a processor; and a non-transitory memory including computer program code; wherein the memory and the computer program code are configured to, with the processor, cause the apparatus at least to: report at least two reported beams to a radio node; receive a configuration from the radio node for at least two configured beams, the at least two configured beams comprising a primary beam and at least one secondary beam; attempt to decode data based on the primary beam, per monitoring occasion for a downlink channel, based on the received configuration; in response to a failure to decode the data based on the primary beam, attempt to decode the data based on the at least one secondary beam over the downlink channel; and transmit or receive information over a scheduling occasion using at least one of the at least two configured beams following a successful decoding attempt.

Abstract: Systems, methods, apparatuses, and computer program products for handling a listen before talk (LBT) failure are provided. One method may include performing, by a user equipment, listen before talk (LBT). When the listen before talk (LBT) is successful, the method may include transmitting an intended transmission subsequent to the listen before talk (LBT). When the listen before talk (LBT) is not successful, the method may include transmitting an indication of listen before talk (LBT) failure by transmitting a portion of the intended transmission subsequent to the listen before talk (LBT).

Abstract: Systems, methods, apparatuses, and computer program products for mobility failure evidence-related operations. A UE may measure, record, and report a channel access waiting (CAW) time period that elapsed from having a handover-related message in a transmission buffer until a channel for transmission of the handover-related message was obtained or until an acknowledgement or negative acknowledgement from a receiver of the handover-related message was received. The CAW time period information may be provided to a network node, and the network node may control mobility robustness optimization based on the received information.
