Systems, methods, apparatuses, and computer program products for power headroom enhancements and triggers for waveforms. A method may include determining, an event which triggers a power headroom report to report a headroom between a current user equipment transmission power and a nominal power. The determination may depend at least partially on a configuration of frequency domain spectrum shaping. The method may also include generating a power headroom report based on the event. The method may further include transmitting the power headroom report to a network element.

Power headroom enhancements and triggers for waveforms

A method including receiving, by a user device from a network node, a configuration including at least an indication to perform spectrum extension; determining a target extension factor for excess band frequency resources for a target spectrum extension; receiving information indicating a set of inband frequency resources allocated to the user device for uplink transmission; determining, by the user device based on the set of inband frequency resources and the target extension factor, the excess band frequency resources for the spectrum extension and/or a total allocation of frequency resources for uplink transmission, wherein the total allocation of frequency resources includes the inband frequency resources and the excess band frequency resources; performing, by the user device, a spectrum extension based on the excess band frequency resources for a set of frequency domain values, to obtain a spectrum extended signal; and transmitting the spectrum extended signal.

Frequency domain resource allocation in wireless networks

According to an example embodiment, an example method may include determining, by a network node in a wireless network, whether a size of a data packet is greater than a threshold size; transmitting, by the network node, the data packet via a frequency interlace if the size of the data packet is less than or equal to the threshold size; transmitting, by the network node, the data packet via contiguous wideband frequency resources if the size of the data packet is greater than the threshold size.

Data transmission via frequency interlace for wireless networks

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).

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.

Mobility failure evidence-related operations

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.
