Abstract: Systems, methods, apparatuses, and computer program products for changing MRB ID without requiring release and add functions. One method may include receiving, by a user equipment, a RRC reconfiguration message from a network entity comprising a MRB. The MRB is identified by a first MRB ID, and the RRC reconfiguration message further comprises a second MRB ID associated with the first MRB ID. The user equipment associates the MRB with the second MRB ID configured for subsequent identification of the MRB. The user equipment receives MBS data through the MRB associated with the second MRB ID.

Abstract: Embodiments of the present disclosure relates to estimating downlink size for a multicast traffic. According to embodiments of the present disclosure, a first device receives downlink control information (DCI) for a multicast traffic. The first device determines field size(s) in the DCI based on one or more parameters which are associated with the field size estimation for the multicast traffic. The first device decodes the DCI based on the determined field sizes(s). In this way, the DCI can be blindly decoded correctly.

Abstract: Disclosed is a method comprising determining an alternative set of random-access resources based at least partly on an estimated number of idle and/or inactive terminal devices, wherein the alternative set of random-access resources comprises at least one or more random-access resources that are not comprised in an initial set of random-access resources indicated by an initial set of configuration parameters at the estimated number of idle and/or inactive terminal devices. A group paging message indicating at least the alternative set of random-access resources and a group identifier is transmitted to the estimated number of idle and/or inactive terminal devices.

Abstract: According to an aspect, there is provided a distributed unit for a distributed access node. The distributed unit maintains, in a memory, information on a configuration of a first radio link control leg for a unicast data radio bearer or a single cell multicast radio bearer for point-to-point transmissions and a configuration of a second radio link control leg for the single cell multicast radio bearer for point-to-multipoint transmissions. The distributed unit receives channel state information and/or hybrid automatic repeat request feedback associated with one of the first and second radio link control legs being active from a terminal device and determines, based thereon, that improved efficiency is enabled if the second radio link control leg is set as active. The distributed unit transmits, to the terminal device, an activation command for activating downlink monitoring and decoding using the group radio network temporary identifier.

Abstract: This disclosure presents solutions for allowing a transmitter of multicast broadcast services (MBS) to select a mapping algorithm for mapping synchronization signal block (SSB) beams to slots with PDCCH monitoring occasions (MOs) of a multicast control channel (MCCH) window duration. The transmitter can be a communication node. In some example embodiments, the transmitter can receive assistance information from one or more UEs and utilize that assistance information to determining the mapping algorithm to utilize. The transmitter can determine whether across MCCH window duration mapping is enabled or disabled. The transmitter can determine the pattern of repetition of SSB beams when there are more slots with PDCCH MOs in the MCCH window duration than there are SSB beams in a set of SSB beams where each SSB beam has at least one UE interested at MBS. The SSB beam mapping can be communicated to MBS receivers, allowing them to optimize operations by listening to their respective appropriate monitoring occasions.

Abstract: Embodiments of the present disclosure provide methods, apparatus and computer program products for providing broadcast/multicast services. A method at least partially implemented at an application server comprises transmitting a resource request message to a first broadcast/multicast control node (BM-CN), requesting an allocation of broadcast resource for delivering a multimedia broadcast/multicast service (MBMS) user service; transmitting a further resource request message to a second BM-CN, requesting a further allocation of broadcast resource for delivering the MBMS user service; receiving a first response message from the first BM-CN and a second response message from the second BM-CN, the first response message indicating a first broadcast resource allocated by the first BM-CN for the MBMS user service, and the second response message indicating a second broadcast resource allocated by the second BM-CN for the MBMS user service; and indicating information about the second broadcast resource to the first BM-CN and/or indicating information about the first broadcast resource to the second BM-CN. Methods at the BM-CN and a RAN network node, and corresponding apparatus are also provided.
