1. A method of wireless communication performed by a receiving (Rx) user equipment (UE), comprising:
receiving, from a transmitting (Tx) UE, sidelink control information (SCI) that includes sidelink control information part 1 (SCI-1) and sidelink control information part 2 (SCI-2);
determining an Rx-side block error rate (BLER) based at least in part on the SCI and at least two of:
a number of SCI-2s over a configured sliding window,
a total number of transmissions from the Tx UE over the configured sliding window,
a hybrid automatic repeat request retransmission number indicated in the SCI-2,
a sequential transmission counter indicated in SCIs received over the configured sliding window,
a signal-to-interference-plus-noise ratio (SINR) from a demodulation reference signal (DMRS) associated with the SCI-1, or
a fixed SCI transport block size and modulation and coding scheme; and
performing a beam failure recovery based at least in part on the Rx-side BLER satisfying a threshold.
