The method includes an increase circuit that, after determining that the received MTU is supported, changes the MTU of the network node's ports to match the received MTU, and a message circuit that, after determining that the received MTU is supported, sends a message with the MTU to network nodes connected to ports of the network node.

Abstract: Various designs for implementing bandwidth part (BWP) full-duplex (FD) are discussed. A base station serving a plurality of user equipments (UEs) over a component carrier bandwidth (CC BW) receives a reference signal from a UE while transmitting downlink traffic to another UE over a part of the CC BW. The base station determines, based on the reference signal, a level of interference on transmissions over the part of the CC BW, and, based at least in part on interference cancelation capabilities of the base station and the level of interference, at least one portion of the CC BW for full-duplex operations. The base station activates full-duplex operations for the at least one portion of the CC BW, which includes receiving from the UE while transmitting to another UE over the same portion of the CC BW. Other aspects and features are also claimed and described.
