Abstract: Embodiments of the present disclosure relate to methods, apparatuses and computer readable storage media for search space configuration for multicast traffic. According to embodiments of the present disclosure, a first device determines, from a group of search space sets configured to the first device, at least one search space set for monitoring multicast traffic from a second device, based on at least one of a priority of the multicast traffic and respective types of the search space sets. The first device monitors the multicast traffic from the second device in the at least one search space set. The solution enables multicast traffic to be monitored in a common search space set, a user-specific search space set or a multicast search space set in different scenarios.

Abstract: Embodiments of the present disclosure relate to downlink control and data channel configuration. A method comprises: determining, at a first device, a transmission scheme of control information for a second device based on at least one multicast and broadcast service related criterion, the control information related to scheduling multicast service traffic to the second device; transmitting, to the second device, configuration information for causing the second device to obtain the control information; and transmitting, to the second device and based on the determined transmission scheme, the control information on a control channel between the first device and the second device. In this way, the correlation between the scheduling mechanism of multicast traffic on the downlink data channel and the transmission mechanism of control information on the downlink control channel can be decoupled, resulting in a flexible and dynamic downlink channel configuration and an increased radio resource efficiency.

Abstract: There is provided an apparatus. The apparatus is configured to: store information of a multicast session, the information comprising at least one identifier of the multicast session, and information about access to different content for the multicast session in a plurality of different location areas; and, in response to a request from a second apparatus, provide to the second apparatus information about access to content of the multicast session in at least one of the plurality of different location areas.

Abstract: There are provided measures for enabling/realizing broadcast session establishment, particularly improved broadcast session establishment within a multicast/broadcast service. Such measures exemplarily comprise that an access management element or function in a mobile communication system issues, in response to a request of broadcast session establishment from a session management element or function, one or more requests of broadcast session establishment operation to one or more radio access elements or functions, issuing a response of broadcast session establishment to the session management element or function, and provides an indication of completion of broadcast session establishment operation at the radio access elements or functions to the session management element or function upon obtaining a response of broadcast session establishment operation from all of the radio access elements or functions.

Abstract: Example embodiments of the present disclosure relate to polling a device for multicast broadcast service interest indication. A first device receives, from a second device, a physical downlink control channel (PDCCH) order addressed by a paging radio network temporary identifier for the first device. The PDCCH order comprises a request for an indication that at least one multicast broadcast service is to be received by the first device. The first device transmits, to the second device, a random access preamble associated with the at least one multicast broadcast service as a response to the request. Through this solution, the first device that monitors the single PDCCH order may have less power consumption.

Abstract: Systems, methods, apparatuses, and computer program products for common frequency resource, control resource set configurations, and common frequency resource switching. The method may include receiving, from a network element, a configuration for monitoring at least one broadcast services on a communication resource. The method may also include monitoring the at least one broadcast service on the communication resource based on the configuration. According to certain example embodiments, the communication resource may be a subset of an initial bandwidth part, or the communication resource may include an initial bandwidth part as a subset of the communication resource.

Abstract: Systems, methods, apparatuses, and computer program products for informing a central unit control plane regarding the capabilities and/or service area of a central unit user plane are provided. For example, a method may include notifying, by a central unit user plane to a central unit control plane using a message, at least one of an offered multicast radio bearer configuration to be shared in relation with a multicast/broadcast session served by the central unit user plane and one or more offered service area corresponding to the central unit user plane.

Abstract: A method comprises receiving a handover request from a source BS, the handover request comprising a request for a handover of a UE involved in at least two QoS flows using a first MRB with the source BS, wherein the apparatus is using at least a second MRB for other UEs; starting to buffer packets for the UE; receiving a subsequent message comprising, for each of the at least two QoS flows, a CN SN of a first packet not transmitted by the source BS for that QoS flow; identifying a second packet with the highest protocol entity SN according to a protocol entity transmission order of the second MRB among packets which the source BS has delivered to the UE using the first MRB and the apparatus has transmitted to the other UEs using the second MRB; and transmitting a message configuring the UE to use the second MRB.

Abstract: An apparatus including at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to identify at least one of a plurality of user equipment based on a pre-determined channel quality. A determination is made that point-to-point efficiency is greater than point-to-multipoint efficiency. At least one identified UE with worse channel condition is switched from point-to-multipoint to point-to-point.

Abstract: Systems, methods, apparatuses, and computer program products for distributing multicast packets in individual protocol data unit (PDU) sessions are provided. One method may include receiving, at a user plane node, a request from a session management node, to receive packets for a multicast session and/or to send packets from the multicast session within a protocol data unit (PDU) session. The method may also include determining whether the user plane node was already configured to receive incoming packets for the multicast session, and informing the session management node as to whether the user plane node was already configured to receive the incoming packets for the multicast session.
