  • Patent number: 12677114
    Abstract: 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).

  • Patent number: 12568346
    Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may transmit system information indicating multiple multicast-broadcast network areas, and may further provide configuration information for each multicast-broadcast network area indicating a location of multicast scheduling information (MSI). The MSI may include an indication of frequency resources on which to receive broadcast or multicast services. The MSI may indicate specific services for an multicast-broadcast network area that are provided via the different frequency resources (for example, different cells, carriers, channels, among other examples). In some examples, the base station may schedule broadcast or multicast services across frequency resources via semi-persistent scheduling. The MSI may indicate a redundancy version configuration (for example, time and frequency patterns for combined redundancy version broadcast transmissions).
