Depends on how the rpm requirements are listed.
In most cases, rpm A would say reuiqres: B >= 1.1
in that case, you can upgrade B alone. If the rpm A required that exact ver-rel of B, ie, requires: B = 1.1 then you have to upgrade both.
Also, sometimes there are circular dependencies which would also require you to upgrade both of them together. When you try to upgrade the package B, rpm would let you know...

Subject: Re: -Upgrading RPMs
a) If A-1-1 needs B-1-1 and we want to Upgrade only
B-1-1 , then would the RPM allow to upgrade B-1-1 ?
b) If we are not aware of what packages need B-1-1 can
we still simply go ahead and upgrade only B-1-1 ?
using the -Upgrade command
For e.g rpm -Uvh B-2-2.rpm
Thanks
