This application discloses a communications system, a communication method, and an apparatus thereof. The system includes: a multicast session management network element, an access and mobility management network element and a user plane function network element. The multicast session management network element sends a first multicast session request carrying a multicast session context to the access and mobility management network element to request to establish a multicast session based on the multicast session context; and sends a second multicast session request to the user plane function network element, where the second multicast session request carries user plane forwarding-related information indicating a user plane forwarding rule of the multicast session. The access and mobility management network element sends the first multicast session request to an access network node. The user plane function network element sets, based on the user plane forwarding-related information, the user plane forwarding rule of the multicast session.

Certain aspects of the present disclosure provide techniques for group semi-persistent scheduling (SPS) for path diversity. A method that may be performed by a node includes configuring one or more groups of user equipments (UEs) with one or more SPS resources. The node sends a downlink control information (DCI) to activate one of the SPS resources for one of the groups of UEs and transmits data to the group of UEs using the activated SPS resource. A first UE may receive data from the node using the activated SPS resource and retransmit the data to the second UE. The first helping UE and the second targeted UE may be identified based on the higher layer configuration with the SPS resources, based on information in the DCI, and/or based on information sent with the data.

A base station configure to receive, from a second base station, a retrieve user equipment context request message that includes a resume identity. The base station may further transmit a response message that includes one or more temporary mobile group identities (TMGIs) of one or more multimedia broadcast multicast service (MBMS) services that the wireless device is receiving or interested to receive. In an embodiment, the response message may be based on the resume identity.

Methods, apparatus, and processor-readable storage media for pairing multiple devices into a designated group for a communication session are provided herein. An example computer-implemented method includes processing, via at least a portion of multiple processing devices, information associated with a network in connection with one or more device pairing requests from one or more of the processing devices; implementing, via at least one the multiple processing devices, a pairing algorithm, wherein the pairing algorithm comprises searching for one or more of the processing devices, in accordance with one or more temporal values associated with the at least one processing device and at least one of the one or more device pairing requests corresponding thereto, and one or more pairing parameters; and automatically pairing, via the network and based on the pairing algorithm, the at least one processing device to one or more of the processing devices.

A method for initiating a communication within a regroup of communication groups, the method being implemented by a network according to the 3GPP MCS standard including at least two systems separated by a gateway hiding or deleting information necessary for initiating a communication in a global communication group to which entities distributed in the at least two systems are affiliated, the method especially including directly transmitting, between a participating server managing the client entity initiating the communication and a non-controlling server of the global communication group, an invite message according to the SIP protocol. Furthermore, some information is added in the different transmissions in order to allow additional checks by the different entities.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration for a shared physical downlink shared channel (PDSCH). The UE may receive a first communication via the shared PDSCH and a first bearer based at least in part on the configuration, the first communication being one of a unicast communication or a multicast/broadcast communication. The UE may receive a second communication via the shared PDSCH and the first bearer or a second bearer based at least in part on the configuration, the second communication being the other of the unicast communication or the multicast/broadcast communication. Numerous other aspects are provided.

A wireless access node (e.g. a master eNB (MeNB)) is described for a wireless communication system that comprises a first wireless access network and a second wireless access network supporting a dual connectivity terminal device arranged to communicate with both the wireless access node (MeNB) on the first wireless access network and a second wireless access node (e.g. a secondary eNB (SeNB)) on the second wireless access network is provided. The wireless access node comprises a communication unit and a controller. The controller is operably coupled to the communication unit and configured to control the communication unit to transmit a first message including configuration information for a secondary cell group (SCG) to perform a certain action, to the other base station, and to receive a second message in response to the first message from the other base station, and to control the communication to transmit a third message based on the second message to the terminal, wherein the configuration information includes multimedia broadcast multicast service (MBMS) interest information.
