I am not sure about the 5245bis, but in RFC 5245 section 4.3 (
https://tools.ietf.org/html/rfc5245#section-4.3):

If the agent is utilizing RTCP, it MUST encode the RTCP candidate
using the a=rtcp attribute as defined in RFC 3605
<https://tools.ietf.org/html/rfc3605>[RFC3605
<https://tools.ietf.org/html/rfc3605>].  If RTCP is not in use, the
agent MUST signal that using b=RS:0 and b=RR:0 as defined in RFC 3556
<https://tools.ietf.org/html/rfc3556> [RFC3556
<https://tools.ietf.org/html/rfc3556>].
