Abstract: Aspects of the subject disclosure may include, for example receiving a group of mobility measurements associated with a communication device. A group of communication devices is communicatively coupled to the mobile IAB node device as a mobility group. Further embodiments include receiving a request from the communication device to join the mobility group, selecting the communication device to join the mobility group based on the group of mobility measurements, and transmitting a confirmation message to the communication device. The confirmation message indicates that the mobility group comprises the communication device. Other embodiments are disclosed.

Abstract: The described technology is generally directed towards operating a user equipment node as a scheduler user equipment (e.g., which can be a local manager of other nodes in a group). The scheduler user equipment receives a scheduling request for the scheduling of the resources for transmission of data by a transmitter user equipment, and based on the traffic type requested, schedules the transmitter user equipment and receiver user equipment(s) with scheduling data/allocated radio resources. The transmitter user equipment can directly transmit to the receiver user equipment(s) on the allocated radio resources, e.g., without further involvement of the scheduler user equipment/local manager. For cellular data, the scheduler user equipment can schedule the transmitter user equipment to transmit to the scheduler user equipment as a receiver node.

Abstract: Various embodiments disclosed herein provide for a multi-beam Listen Before Talk which is a coexistence mechanism used by wireless technologies such as Wi-Fi, to access unlicensed shared spectrum, such as the ISM UNII bands (5 GHz). The embodiments disclosed herein enable a transceiver to determine whether or not there is activity on a beam to avoid causing interference. The transceiver can determine that there is activity in a certain direction, and then avoid transmitting on a beam in that direction until the activity ceases. While there is activity in a first beam, the transceiver can continue to transmit on other beams that will not cause interference with a transmission associated with the first beam.

Abstract: Facilitating a time-division multiplexing pattern-based solution for a dual-subscriber identity module with a single radio in advanced networks (e.g., 5G, 6G, and beyond) is provided herein. Operations of a method can comprise obtaining, by a network device comprising a processor, multiple time-division multiplexing patterns applicable to a mobile device. The multiple time-division multiplexing patterns indicate respective repeating patterns of an on state and an off state of a defined identity of the mobile device. The method also can comprise facilitating, by the network device, a transmission, to the mobile device, of information indicative of the multiple time-division multiplexing patterns. In an example, the mobile device can be configured to operate with at least two subscriber identity modules.

Abstract: Aspects of the subject disclosure may include, for example, systems and methods for performing inter-donor migration of backhaul links between integrated access and backhaul (IAB) nodes in a communication network. A child node may have resources partitioned to create multiple logical distributed units (DUs). Devices connected to one logical DU may be handed over to another logical DU during the migration. Other embodiments are disclosed.

Abstract: Aspects of the subject disclosure may include, for example, performing resource coordination to support integrated access and backhaul (IAB) link migration events in 5G new radio (NR) networks. Migration events may be a result of any factor including handovers, secondary cell changes, or radio link failures. Coordination may be achieved by an IAB node configuring or reconfiguring a distributed unit (DU) to be compatible with a backhaul link of a second IAB node. Other embodiments are disclosed.

Abstract: The technology is generally directed towards configuring, coordinating, and operating across multiple frequency carriers or bands on one or more access and backhaul links. An integrated access and backhaul (e.g., child) node, for example, determines first multiplexing capability data representative of a first multiplexing capability for a first frequency resource, and determines second multiplexing capability data representative of a second multiplexing capability for a second frequency resource. The first and second multiplexing capability data for the first and second resources are communicated to a second (e.g., parent) integrated access and backhaul node. Quality of service can be applied across multiple frequency carriers utilized by the integrated access and backhaul node for access and backhaul links. Also described is supporting multifrequency operation outside of the radio access network for non-new radio-based traffic backhauling.

Abstract: The technology is generally directed towards sending multiplexing capability data between integrated access and backhaul (IAB) nodes, such as for use in coordinating the communications of the nodes, including using multiplexed resources. In addition to different types of multiplexing capabilities, the technology facilitates sending condition data (e.g., measured interference, traffic, beam data and the like) by which a parent node can make determinations with respect to coordinating (e.g., scheduling and/or guard symbol usage) child node communications. Further, the technology provides for sending usage criterion data with the multiplexing capability indication data, such that, for example, any specified usage criterion needs to be satisfied before a particular type of multiplexing can be used.

Abstract: An integrated access and backhaul network is provided with network nodes that can establish timing synchronization with any other network nodes. In an embodiment, network nodes in a multi-hop integrated access and backhaul network have a hop order of n, wherein n represents a number of hops from a node connected to the core network via a wired connection. In an embodiment, instead of using the network node with a hop order of 0 as the timing synchronization reference for over-the-air synchronization, any network node can use any other network node as a synchronization reference. A relay node can first establish a wireless link to said arbitrary node. Said wireless link is then used to synchronize the relay or IAB node using a Precision Time Protocol (PTP) implementation.

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.
