Abstract: Facilitating a group hybrid automatic repeat request procedure for sidelink group-case in advanced networks (e.g., 4G, 5G, 6G, and beyond) is provided herein. Operations of a method can comprise determining, by a first device comprising a processor, that first information received via a sidelink control channel is successfully decoded and that second information received via a sidelink shared channel is not successfully decoded. The first information and the second information can be received from a second device. Further, the method can comprise transmitting, by the first device, negative acknowledgement data based on a group hybrid automatic repeat request feedback procedure. The method also can comprise receiving, by the first device, retransmission of the second information via the sidelink shared channel from a group of devices in response to the negative acknowledgement data.

Abstract: In a 5G network, an integrated access and backhaul (IAB) deployment in a 5G network, can enable aggregation of multiple user equipment (UE) bearers into backhaul bearers based on factors such as route information of UE bearers and quality of service of UE bearers. Additionally, reconfiguration of backhaul bearers, based on triggers, such as route changes for UE bearers can increase network efficiency for a 5G or other next generation network.

Abstract: One subscriber identity module (SIM) can transmit data in active mode while another SIM is in an idle mode. However, paging for the SIM in idle mode can occur based on a discontinuous reception configuration (DRX) cycle of the active SIM. For example, when the DRX of the active SIM indicates that the active SIM is in an idle state, then the SIM that is currently in an idle state can send messages and vice versa. The DRX cycle information can be exchanged between a first core network and a second core network. Each core network can belong to the same or different mobile network operator and can have separate radio access networks (RAN) or share the RAN. The DRX cycle information and/or a time-division multiplexing (TDM) pattern can be exchanged over the air via a system information broadcast message.

Operations of a method can comprise facilitating, by a first communications device comprising a memory and a processor, an establishment of multiple-connectivity for communication links between a second communications device and a third communications device. Facilitating the establishment of the multiple-connectivity for the communication links can comprise facilitating establishing a communication link between the second communications device and the third communications device. Facilitating the establishment of the multiple-connectivity for the communication links also can comprise facilitating establishing a first communication relay link between the second communications device and the first communications device and a second communication relay link between the first communications device and the third communications device.

Abstract: A user equipment can send a notification to a network node indicating that the user equipment is entering a battery saving mode of operation. Reduced physical layer procedures can be implemented based on reduced capabilities indicated by the user equipment. Reduced physical layer procedures can also be implemented based on the network node's reconfiguration of parameters to facilitate the activation of the reduced physical layer procedures. The user equipment can also send to the network node recommendations of reduced physical layer procedures.

Abstract: The technologies described herein are generally directed toward facilitating centrally assisted associations with a local manager by peers in a peer to peer wireless system. According to an embodiment, a system can comprise a processor and a memory that can store executable instructions that, when executed by the processor, facilitate performance of operations. The operations can include identifying a group of local managers of a group of user equipments. The operations can further include receiving, from a network device, a criterion for selecting a local manager from the group of local managers of the group of user equipments, wherein the criterion is based on an association parameter selected by the network device.

Abstract: The described technology is generally directed towards an autonomous topology management scheme in a wireless communications network that establishes a hierarchical structure from a peer-to-peer network without assistance from the wireless network. A group of user equipments negotiate with each other to elect a local manager that acts as a base station by which other user equipments of the group can access network resources. Described is an example voting scheme by which the negotiation process elects the local manager for a term.

Abstract: Various embodiments disclosed herein provide for an enhanced timing advance scheme to support MU-MIMO in an integrated access and backhaul system. The timing advance scheme disclosed herein aligns the arrival time between backhaul links and access links to enable MU-MIMO gain at the receiver side. In the integrated access and backhaul system, which comprises distributed nodes, the timing advance offset for an access link transmission (a transmission to a node further away in hops from the core network, or to a user equipment device) can be modified by offsetting it with the timing advance of the backhaul link (e.g., from a parent node). This enables the arrival time for transmissions, both access link transmissions from the UE or child node, and backhaul link transmissions from a parent node to arrive at the same time.
