Abstract: A base station configured to perform a power scaling in a wireless communication system includes at least one processor configured to receive signals from one or more user equipment (UE), the signals including at least one parameter indicative of corresponding operating conditions at the one or more UEs, determine an initial synchronization signal block (SSB) transmission power, determine, based on the at least one parameter, that the initial SSB transmission power is to be adjusted to affect the corresponding operating condition, responsive to determining that the initial SSB transmission power is to be adjusted, compute a first scaling value, compute a first scaling factor, adjust the initial SSB transmission power based on the first scaling value and the first scaling factor to compute an adjusted transmission power, and transmit the SSB based on the adjusted transmission power.

Abstract: A base station configured to perform a power scaling in a wireless communication system includes at least one processor configured to receive signals from one or more user equipment (UE), the signals including at least one parameter indicative of corresponding operating conditions at the one or more UEs, determine an initial channel state information-reference signal (CSI-RS) transmission power, determine, based on the at least one parameter, that the initial CSI-RS transmission power is to be adjusted to affect the corresponding operating condition, responsive to determining that the initial CSI-RS transmission power is to be adjusted, compute a scaling value, compute a scaling factor, adjust the initial CSI-RS transmission power based on the scaling value and the scaling factor to compute an adjusted transmission power, and transmit the CSI-RS based on the adjusted transmission power.

Abstract: Various arrangements for dynamically adjusting physical resource block (PRB) usage on a cellular network are presented. A primary entity may be determined to be exercising its priority to spectrum overlapping PRBs used by the cellular network. A frequency band being used by the primary entity based on measuring the signal strengths of wireless transmission by the primary entity can be determined. Subcarriers of the PRBs are identified that overlap the frequency band. A predefined Physical Random Access Channel (PRACH) format can be selected based at least in part on the identified subcarriers. A predefined Physical Uplink Control Channel (PUCCH) format can be selected based at least in part on the identified plurality of subcarriers.

Abstract: Systems and methods for enhanced PRACH 5G configuration by preventing interference with signal transmission. One such method includes: implementing a PRACH configuration in which the same root sequence index (RSI) is utilized across the sectors of the site, implementing the PRACH configuration in which a time shift is utilized for each preamble that provides each preamble with its own time slot, enabling multiple UEs to each send a preamble that is time shifted to arrive at the gNB at different times and avoid a RAPID (Random Access Preamble Identifier) mismatch, and receiving preambles that are frequency shifted and reducing PRACH interference among different sectors that causes a degradation of PRACH performance using shifts in time domain.
