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). Such collaborative resource allocation and configuration may be effectuated using a novel architecture for the signaling messages between the CU and the DUs.

Abstract: A wireless communication method includes receiving, by a wireless communication device from a network, first downlink control information on a first downlink channel in a first frequency resource. The first downlink control information schedules a first Transport Block (TB). The first downlink channel is specific to the wireless communication device. The method further includes receiving, by the wireless communication device from the network, the first TB on a second downlink channel in a second frequency resource. The first TB is received by a plurality of wireless communication devices. The second downlink channel is common to the plurality of wireless communication devices.

Abstract: This disclosure relates to methods and devices for configuring discontinuous reception for sidelink transmission between communication terminals in a wireless communication network. In one implementation, the method may include receiving a first discontinuous reception (DRX) configuration information from a wireless network access node, receiving a second DRX configuration information from a second user equipment. The method may further include obtaining a DRX configuration scheme for a sidelink communication between the first user equipment and a second user equipment based on the first DRX configuration information and the second DRX configuration information.
