1. A method comprising:
identifying, by a first device and for a first link with a second device, a switch in a first bandwidth part to a second bandwidth part for the first link, the first link associated with a second link having a third bandwidth part, the identifying comprising identifying the switch from a first division duplex type to a second division duplex type;
based at least on identifying the switch from the first division duplex type to the second division duplex type, determining, by the first device, whether a bandwidth band between the second bandwidth part and the third bandwidth part satisfies a threshold guard band; and
determining to maintain the third bandwidth part for the second link in response to determining that the bandwidth band between the second bandwidth part and the third bandwidth part satisfies the threshold guard band.
