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: Facilitating shared demodulation reference signal design for control channels in a wireless communications system 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 evaluating a usage parameter of a mobile device for application of channel demodulation reference signal reuse by the mobile device. In response to a first determination that the usage parameter satisfies a condition relative to a threshold usage parameter, the operations can comprise facilitating a first transmission to the mobile device to implement the channel demodulation reference signal reuse by the mobile device. In response to a second determination that the usage parameter does not satisfy the condition relative to the threshold usage parameter, the operations can comprise facilitating a second transmission to the mobile device to implement usage of separate channel demodulation reference signals.

Abstract: An example method may include a processing system of a channel sounding receiver having a processor receiving from a base station, at a location, a channel sounding waveform via a plurality of carriers, sampling the channel sounding waveform via the plurality of carriers to generate a plurality of per-carrier time domain sample sets, and processing the plurality of per-carrier time domain sample sets via a plurality of discrete Fourier transform modules to provide a plurality of per-carrier frequency domain sample sets. The method may further include the processing system aligning the plurality of per-carrier frequency domain sample sets in gain and phase to provide a combined frequency domain sample set and measuring a channel property at the location based upon the combined frequency domain sample set.

Abstract: A system employing resource element mapping for efficient use of the downlink control channel is provided for a wireless communication system. In one example, a method comprises: generating, by a base station device comprising a processor, resource element mapping signaling, wherein the resource element mapping signaling is performed per subgroup of physical resource blocks of a group of physical resource blocks; transmitting, by the base station device, a first resource element mapping pattern to a first subgroup of the group of physical resource blocks; and transmitting, by the base station device, a second resource element mapping pattern to a second subgroup of the group of physical resource blocks, wherein the first resource element mapping pattern is distinct from the second resource element mapping pattern.

Abstract: The disclosed subject matter is directed towards scheduling and Hybrid Automatic Repeat Request (HARQ) operations by which nodes in a three party communication system can communicate. To schedule a data transmission from a transmitter node to receiver node(s), a local manager/scheduler node sends common downlink control information to the transmitter and receiver nodes. Via a scheduling request, the transmitting node can request the scheduling of the data transmission by the local manager node. The technology facilitates unicast and broadcast/multicast data transmissions; for a unicast data transmission, the scheduling request identifies the receiving node. The transmitting node can explicitly acknowledge reception of the downlink control information to the local manager node, or the local manager node can detect the data transmission, when it occurs, as an implicit acknowledgment that the common downlink control information was successfully received.

Abstract: Various embodiments disclosed herein provide for power control system in a multi-hop integrated access and backhaul network. In a multi-hop integrated access and backhaul network a donor node can communicate with user equipment devices and relay nodes that have varying power levels, and to avoid receiving uplink transmissions with varying power levels which can impact automatic gain control systems and lower overall throughput, the power control system disclosed herein can manage the power levels of the relay node in order to reduce the difference in power levels. In one embodiment, the power control system can schedule relay node devices to transmit uplink transmissions alongside UE devices that have a high signal strength. In another embodiment, the power control system can schedule relay nodes and UE devices to separate symbols within a time slot. In another embodiment, the power control system can perform closed loop power control management at the relay node to reduce the power level for the uplink transmission.

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: Facilitating notifications to indicate failed code block groups is provided herein. A method can comprise determining a value of a confirmation bit received in a transmission based on a first determination that a new data indicator is set to a null indication and performing an action from a group of actions. The group of actions can comprise decoding a first group of code block groups of the code block groups based on a second determination that the value of the confirmation bit for the first group of code block groups is a first value. The group of actions can also comprise decoding the code block groups based on a third determination that the value of the confirmation bit for the code block groups is set to a second value and sending a report indicating at least one of the code block groups for which the transmission failed.
