1. A method for managing carrier frequency assignment to a user equipment device (UE) by a base station, wherein the base station provides a coverage area on which to serve UEs, and wherein the coverage area operates on a plurality of carriers, the method comprising:

  • determining, by the base station, that a UE is circuit switched fallback (CSFB) capable and that the base station is currently serving a relay on a first carrier of the plurality of carriers; and

    based on at least the determining that the UE is CSFB capable and that the base station is currently serving the relay on the first carrier, assigning, by the base station, the UE to operate on a carrier of the plurality of carriers other than the first carrier rather than having the UE operate on the first carrier on which the base station is currently serving the relay.
