Methods, apparatus and systems for switching between bandwidth parts

This disclosure describes an architecture for supporting MBS sessions in a wireless access network. Each of such MBS sessions is flexibly and dynamically delivered by the access network into one or more Point-To-Point (PTP, or unicast) and Point-To-Multipoint (PTM, or multicast) delivery instances. As such, a subset of the UEs participating in the MBS may be configured to receive the MBS session in a PTP-like manner and quality. The architecture further allows for access network level switching of one or more of the UEs participating in the MBS session between the PTP mode and PTM mode. Such switching are effectuated dynamically without involvement of application layer. The resource allocations and configuration for the PTP and PTM delivery instances may be performed in the access network collaboratively between a central unit (CU) and one or more distributed units (DUs). Such collaborative resource allocation and configuration may be effectuated using a novel architecture for the signaling messages between the CU and the DUs.

Access network signaling and resource allocation for multicast/broadcast sessions

This disclosure relates to mechanisms for allocating and mapping wireless communication resources for a multicast/broadcast session in a wireless network. In some exemplary implementations, data flows in a multicast/broadcast session may be duplicated and adaptively and dynamically mapped to multiple independent radio bearers, where each of these multiple independent radio beaters may be configured to either multicast the multicast/broadcast data to a group of target user equipments or unicast the multicast/broadcast data to a single user equipment.
