Abstract: A method and apparatus are provided for pre-emption, congestion control, and Tx/Rx alignment for use by a partial sensing UE. A method includes measuring resources within a first window; determining a number of the measured resources having an RSSI greater than a first threshold; determining a CBR based on the measured number of resources; and determining a CR limit based on the determined CBR and transmission priority. Determining the CBR based on the measured number of resources includes comparing a total number of measured resources within the first window to a second threshold; in response to the total number of measured resources being less than the second threshold, determining the CBR as a pre-configured CBR; and in response to the total number of measured resources being greater than or equal to the second threshold, determining the CBR based on a ratio of the number of the measured resources having the RSSI greater than the first threshold to the total number of measured resources within the first window.

Abstract: A synchronization detection method for new radio (NR) sidelink. In some embodiments, the method includes calculating a first delay compensated input signal, calculating a first correlation value, calculating a first correlation power, calculating a first weighted correlation power, and detecting a synchronization signal. The first delay compensated input signal may be based on an input signal, and an index of a first tap value. The first correlation value may be based on a first candidate sequence and the first delay compensated input signal. The first correlation power may be based on the first correlation value. The first weighted correlation power may be based on a first weighting factor, and the first correlation power. The detecting of the synchronization signal may include using the first weighted correlation power.
