Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects. a user equipment (UE) may transmit a first message of a four-step random access channel (RACH) procedure to a base station. The UE may receive a second message of the four-step RACH procedure. The UE may transmit a third message of the four-step RACH procedure. The UE may determine that the third message was not successfully decoded by the base station. The UE may retransmit the third message based at least in part on applying a power boosting algorithm to increase an uplink transmission power. wherein the power boosting algorithm is applied based at least in part on a power offset between the third message and the first message satisfying a threshold and a transmit power control (TPC) command not being received from the base station. Numerous other aspects are described.

Abstract: Apparatus and methods are disclosed for determining, on a small form factor 5G communication device, the range of a target object include receiving, at a receiving antenna of the small form factor communication device, a composite signal where the composite signal includes a target reflection signal and a mutual coupling (MC) leakage signal, generating a composite beat waveform by mixing the composite signal with an original signal, where the composite beat includes target beat and MC leakage beat waveform components, isolating the target beat waveform by subtracting from the composite beat waveform a weighted, k-delayed composite beat waveform, where for a configured k the target beat waveforms are uncorrelated and the MC leakage beat waveforms are correlated, and determining, using the target beat waveform, a range of the target object from the small form factor device.
