Techniques are described for improving service continuity for Multicast and Broadcast Services (MBS) communications during handover. Techniques are included for supporting lossless handover and data forwarding during handover for peer-to-multiple (PTM) MBS transmission. Lossless handover may be achieved in part by the user equipment (UE) providing to the target base station an indication of the next packet of the MBS session to be received following an RRC reconfiguration message, and an indication of any MBS packets provided by the source base station prior to the RRC reconfiguration message that were not properly received by the UE. Data forwarding may be performed from the source base station to the target base station if the MBS session was not configured on the target base station prior to the handover. Data forwarding may be omitted if the MBS session was configured on the target base station prior to the handover.
A method of performing communications of a Multicast and Broadcast Services (MBS) session, the method comprising:
An apparatus, comprising:
A non-transitory computer-readable memory medium storing instructions that, when executed by a processor of a target base station of a wireless communication network, cause the target base station to:
