1. A method for decoding a coded video sequence by at least one processor, the method comprising:
obtaining the coded video sequence; and
decoding the coded video sequence,
wherein a value of a temporal sublayer identifier of a video coding layer (VCL) network abstraction layer (NAL) unit in the coded video sequence is constrained to be less than or equal to a value of vps_max_sublayers_minus1, that specifies a maximum number of temporal sublayers in each coded video sequence referring to the video parameter set (VPS), in the VPS referred to by the VCL NAL unit,
wherein a value of max_tid_il_ref_pics_plus1[i] being zero specifies that inter-layer prediction is not used by non-intra random access point (IRAP) pictures of the i-th layer.
