Abstract: 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.

Abstract: Example embodiments provide a method for acknowledging switching of operation modes for a client device. The method comprises receiving, by a client device, a first indication comprising at least one of a first time duration, a period for repeating the first time duration or an indication of a list of at least two operation modes for the client device. The client device may be configured to receive a second indication comprising instructions for the dynamic switching of operation modes based on the list of at least two operation modes. The client device may be further configured to indicate the selected operation mode to a network device. Devices, methods, and computer programs are disclosed.

Abstract: According to example embodiments, a method may include transmitting, by a user device to a wireless network node, data via a plurality of uplink component carriers including at least a first uplink component carrier and a second uplink component carrier; wherein a first subset of physical resource blocks for the first component carrier is contiguous with a second subset of physical resource blocks for the second component carrier; wherein the first component carrier and the second component carrier have a same power spectral density; and applying a modified radio frequency requirement by the user device wherein the modified radio frequency requirement impacts a transmission power of the first uplink component carrier and of the second uplink component carrier.

Abstract: There is provided an apparatus comprising means for: mapping frequency-domain symbols on a plurality of subcarriers into at least two sets, each set comprising symbols of at least one of the plurality of subcarriers; for each set: performing symbol-wise rotation based on a complex coefficient value and converting the rotated symbols from the frequency domain to the time domain; or converting the symbols from the frequency domain to the time domain and performing symbol-wise rotation on the time-domain symbols based on the complex coefficient value; inserting a cyclic prefix into each time-domain symbol; concatenating the time-domain symbols resulting from the cyclic prefix insertion to create a sub-band waveform; and performing sub-band filtering, interpolation and combination based on the sub-band waveform for each of the sets to generate a single waveform.

Abstract: Devices, methods and computer programs for client device operation mode indication are disclosed. A client device obtains a first indication indicating at least a time duration and at least a first period for repeating the time duration. A downlink control information, DCI, received within the indicated time duration includes a second indication indicating a second operation mode of the client device, and the second indication is not included when the DCI is received outside of the indicated time duration. In response to receiving, at the client device, the DCI from a network node device within the indicated time duration, the client device determines the second operation mode of the client device based on the received second indication, and applies the determined second operation mode of the client device.
