Abstract: The invention concerns a method of performing an intra-segment handover (HO) of a mobile station (MS) from a source access point (AP1) of a tree-structured segment (S1) of an Ethernet-compliant telecommunication network to a target access point (AP2) of said segment (S1), as well as a switch (SW-123) to support the execution of this method. After establishing contact between the mobile station (MS) and the target access point (AP2), the mobile station (MS) sends an update entry request addressed to the segment gateway switch (GW).

The switch (SW-123) checks whether its forwarding database contains a first entry comprising an address of the mobile station (MS) received by means of the update entry request.

Abstract: Aspects of the present disclosure provide methods and apparatuses for transmitting—from all cells belonging to a cluster (e.g., for Joint Processing/Transmission (JP/T) Coordinated Multipoint (CoMP), also referred to as network MIMO (Multiple Input/Multiple Output))—reference signals (RSs) for channel state information (CSI) feedback to user equipment (UE) at the same time and frequency resources. In this manner, data is precluded from interfering with the CSI feedback scheme. Consequently, data need not be determined to reliably estimate the channel(s).
