A base station configures a TDD carrier to have a first TDD configuration for serving of a first UE and to have a second TDD configuration for serving of a second UE concurrently with the serving of the first UE. Such configuring causes the second UE to engage in an uplink communication in at least one subframe in which the first UE engages in a downlink communication, which could lead to interference issues. Therefore, the base station causes the second UE to apply uplink beamforming, so as to help minimize interference resulting from the second UE engaging in the uplink communication in the at least one subframe in which the first UE engages in the downlink communication.
