Abstract: Facilitating virtual carrier aggregation for wideband operation of wireless communication systems is provided herein. A system can comprise: a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations. The operations can comprise: receiving, from a network device of network devices, downlink transmission data comprising downlink control information applicable to a downlink channel of the network device; as a function of the downlink transmission data, adjusting a subband of subbands resulting in an aggregation of multiple subbands; and transmitting uplink radio traffic data via the aggregation of multiple subbands to the network device.

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, an adaptation layer can be configured to perform aggregation of data from UE bearers into backhaul bearers either above or below a radio link control layer. Thus, aggregation of data from UE bearers into backhaul bearers can be performed either above the RLC or below the RLC to take advantage of benefits from both options.

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: 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.

Abstract: Facilitating configurable hybrid automatic repeat request (HARQ) feedback types for new radio sidelink communication can be performed for a 5G wireless network. Based on whether reception of data was successful or not, a reception node can send acknowledgement (ACK) data or negative acknowledgement (NACK) data to a base station using an uplink control signal. Therefore, the feedback data can be used to manage subsequent resource allocation decisions within the 5G wireless network.

Abstract: Facilitating fast multi-beam listen before talk in advanced networks (e.g., 4G, 5G, 6G, and beyond) is provided herein. Operations of a device can comprise determining a first inactivity in a first beam based on a first performance of a first listen before talk procedure in the first beam and, based on determining the first inactivity, analyzing a presence of an activity in a second beam based on a second performance of a second listen before talk procedure in the second beam. Further, the operations can comprise, based on determining a lack of the presence of the activity in the second beam, transmitting a signal via the second beam. In an example, analyzing the presence of the activity in the second beam can be performed prior to completion of the determining the first inactivity in the first beam.

Abstract: Various aspects of the technology described herein are directed towards a generalized beam management framework in which beam management takes into account interference to steer a beam. Aspects comprise configuring a report request comprising a resource setting with channel state information-reference signal resource data and an associated report setting with parameter data corresponding to the one or more channel state information-reference signal resources. The report request is configured to instruct a user equipment device to include interference information when performing user equipment device beam management and reporting. Upon receiving the report request, the user equipment performs a beam measurement operation that includes interference information when generating the beam management report sent to the network device.

Abstract: A two-stage enhanced downlink control channel (DCI) is provided. In one example, a method comprises performing processing to attempt to decode a second stage of DCI without blind decoding and based on resource allocation information (RAI), wherein the decoding the first stage of DCI comprises blind decoding and wherein the second stage of DCI and uplink control information is received after the first stage of DCI. The method also comprises based on successfully decoding the second stage of DCI, decoding a physical data shared channel (PDSCH). In various embodiments in which semi-persistent scheduling is provided, decoding information previously received in a prior transmission time interval can be employed in a current or subsequent TTI to conserve bandwidth and power.

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.
