Abstract: Various techniques are provided for determining, by a network device, a number indicating a quantity of user equipment (UE) that are in an idle state, determining, by the network device, whether the network device can operate in an energy-saving transmission mode based on the number indicating a quantity of UE that are in an idle state, in response to determining the network device can operate in the energy-saving transmission mode using, by the network device, energy-saving transmissions, and notifying, by the network device, at least one UE being served by the network device of the energy-saving transmissions.

Abstract: This document discloses a solution for reducing peak-to-average power ratio in a radio device. According to an aspect, an apparatus includes circuitry configured for performing: acquiring a block of modulated symbols to be transmitted over a radio interface; transforming the block of modulated symbols from a time domain into a frequency domain for sub-carrier mapping; performing a time-domain peak detection procedure on the block of modulated symbols before said transforming; upon detecting at least one peak in the block of modulated symbols during the time-domain peak detection procedure, computing a peak correction signal for the block of modulated symbols and allocating the peak correction signal to one or more sub-carriers dedicated to the peak correction signal in the sub-carrier mapping; and upon detecting no peak in the block of modulated symbols during the time-domain peak detection procedure, omitting said computing and said allocating.
