A system described herein may provide a technique for determining a maximum and/or target output power on a per-beam and/or per-direction basis for a base station of a radio access network (“RAN”) that implements multiple beams for which output power is dynamically adjustable. The maximum and/or target output power for a given beam (or set of beams) for a given time period may be determined based on historical output power information associated with the beam over one or more previous time periods. The maximum and/or target output power may be based on a predicted received signal power within a coverage area of the base station, based on varying levels of output power.

Increased radiated power using multiple antennas is disclosed. In certain aspects, power spectral density limitations on a per antenna basis can be met while increasing radiated power for a shared channel by transmitting the signal over multiple antennas. Further aspects relate to allocating a monolithic block of modulation as a single cluster to minimize the required power back-off and maximize power density.

The disclosure relates to techniques for controlling Specific Absorption Rate (SAR) of radio energy transmission. In particular, the disclosure relates to a radio device and a method for controlling radio energy transmission of a plurality of radio entities to comply with a predefined SAR requirement. Such a radio device includes: a plurality of radio entities configured to transmit radio energy; and a controller configured to control the radio energy transmission of the plurality of radio entities to comply with a predefined Specific Absorption Rate, SAR, requirement, wherein the controller is configured to enable at least two radio entities of the plurality of radio entities operating concurrently based on a shared SAR transmission power restriction which allows the at least two radio entities transmitting concurrently at a predefined duty cycle, in particular at 100% duty cycle, without violating the SAR requirement. The disclosure further relates to a method for dynamic management of a SAR budget across multiple radio entities.

Disclosed are systems and techniques for performing sidelink communications. For instance, a first client device can determine a first transmit power parameter for transmitting sidelink communications. The first transmit power parameter can either be received from a base station associated with the first client device or it can be a default parameter based on the first client device not being associated with a base station. The first client device can transmit, to a second client device, a first sidelink transmission having a first power level corresponding to the first transmit power parameter. The first client device can receive, from the second client device, a first sidelink reception having a second power level corresponding to a second transmit power parameter.
