For example, the proposed methods of the present disclosure may be limitedly applied only to mode 1 operation. For example, the proposed methods of the present disclosure may be limitedly applied only to mode 2 operation. For example, the proposed methods of the present disclosure may be limitedly applied only to pre-configured/signaled (specific) V2X channel/signal transmission (e.g., PSSCH (and/or (associated) PSCCH and/or PSBCH)). For example, the proposed methods of the present disclosure may be limitedly applied only if the PSSCH and the (associated) PSCCH are transmitted adjacent to each other (in the frequency domain). For example, the proposed methods of the present disclosure may be limitedly applied only if the PSSCH and the (associated) PSCCH are transmitted non-adjacent (in the frequency domain). For example, the proposed methods of the present disclosure may be limitedly applied only if the PSSCH and the (associated) PSCCH are transmitted based on the previously configured/signaled MCS (and/or coding rate and/or RB) value/range.
