    Abstract: Apparatuses and methods are provided to enable a receiver device monitoring a control channel configured for carrying information indicating transmission types of point-to-multipoint services detect a point-to-multipoint service of interest. The device can further detect an indication of a transmission type associated with the point-to-multipoint service of interest. In response a request can be sent for a configuration enabling reception of the indicated transmission type of the point-to-multipoint service of interest on a point-to-multipoint traffic channel. In the absence of said further detecting, the device can refrain from sending the request for the configuration for reception of the transmission type of the point-to-multipoint service.

    Abstract: Disclosed are methods and apparatus for multiplexing NACK-only HARQ feedback. A terminal device in a communication network may comprise at least one processor and at least one memory having computer program code stored thereon. The at least one memory and the computer program code may be configured, with the at least one processor, cause the terminal device to perform: receiving, from a network device, one or more uplink control channel configurations for transmitting HARQ feedback for multicast transmission of one or more services; receiving, from the network device, the multicast transmissions of the one or more services; converting HARQ feedback bits of the HARQ feedback for the multicast transmissions of the one or more services; multiplexing the converted HARQ feedback bits into a multiplexed HARQ feedback; selecting a physical uplink control channel (PUCCH) resource for transmission of the multiplexed HARQ feedback; and transmitting the multiplexed HARQ feedback using the selected PUCCH resource.

    Abstract: Network devices and a method for providing a session management function (SMF)-centric multicast and broadcast services (MBS) activation using group paging may include a SMF network device which is caused to receive a MBS activate message, the MBS activate message including a MBS session ID, determine a plurality of deactivated UE devices associated with the MBS session ID, the plurality of deactivated UE devices including idle UE devices, determine at least one AMF network device associated with each of the determined plurality of deactivated UE devices, and transmit an AMF MBS activate message to the AMF network device, the AMF MBS activate message including information related to at least one UE device associated with each of the determined at least one AMF network, the AMF MB S activate message causing the at least one AMF network device to trigger a group paging of the UE device.

    Abstract: Techniques of transmitting and receiving HARQ feedback for point to multipoint data packets include using two different PUCCHs for providing ACK/NACK feedback to a sequence of point-to-multipoint (PTM) data packets. For example, when a gNB sends PTM data packets (e.g., as part of a subscription) to subscriber UE's, each UE sends ACK/NACK messages in response over a first PUCCH which has a smaller bandwidth than a conventional PUCCH under which full uplink control information (UCI) may be sent. In some implementations, the ACK/NACK messages are a single bit. In response to a NACK message from a UE, the gNB allocates a second PUCCH to the UE. The UE then send additional details to explain the NACK message. In some implementations, the additional details include an identifier of a missing data (e.g., packet m of n).

    Abstract: For a source stream of input data where FEC scheme(s) have been used to create a repair stream, transmitting by a network node packet(s) comprising data of the source stream or the repair stream packaged as at least part of PDU(s). An ARQ or HARQ process is applied to the PDU(s). The network node receives feedback information as part of the process corresponding to the PDU(s), including positive ACK/NACK response for the PDUs. The retransmissions of the negatively acknowledged PDU(s) are controlled when the FEC scheme is known not to be able to compensate for loss(e)s of packet(s) contained in the PDU(s) indicated as being negatively acknowledged. A UE receives packet(s), determines loss(es), and, in response to a determination the FEC scheme is known to be able to recover from the loss(es), sends at least one ACK for any lost packets that correspond to the one or more loss(es).

    Abstract: Apparatuses and methods for data duplication are disclosed. Information on one or more user terminals are received by an apparatus from a base station serving the one or more user terminals located in a same host unit. Received information is compared to information of the user terminals the apparatus is serving. Based on the comparison, it is determined that at least some of the one or more user terminals served by the apparatus are located in the same host; and the at least some of the one or more user terminals are scheduled to utilize different radio resources that provide largest frequency or time diversity available between the at least some of the one or more user terminal.
