Abstract: Facilitating energy-efficient wireless communications for advanced networks (e.g., 4G, 5G, and beyond) with low-resolution digital-to-analog converters is provided herein. Operations of a system can comprise determining first values. Respective values of the first values can be digital samples of transmission and reception chains determined based on symbols transformed from bits. The operations can also comprise facilitating a quantization of the first values resulting in second values. Facilitating the quantization can be based on a cost function associated with processing the first values. Further, the operations can comprise outputting the second values as a continuous time signal over antennas of a base station device. The second values can comprise fewer values than the first values.

Abstract: To facilitate signal alignment for an integrated access backhaul (IAB) node, a system can determine a subset of beams that can be used for communication transmissions. Based on a signal quality associated with the subset of beams, the system can indicate that the subset of beams is to be used for the communication transmission. Consequently, the subset of the beams or another subset of the subset of the beams can be utilized for the communication transmission based on the signal quality of the beams.

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: An adaptive downlink control channel structure is utilized for control channel transmission for 5G and other next generation wireless systems. Moreover, the adaptive downlink control channel structure can utilize a reduced length/size to decrease signaling overhead for each transport block. In an aspect, a first downlink control channel structure for a data transmission can be utilized to implicitly indicate redundancy version (RV) and a second downlink control channel structure for a subsequent data transmission can be utilized to explicitly indicate the RV. In another aspect, the RV can be indicative via an adaptive bit load. Further, in yet another aspect, the RV can be indicated based on a joint encoding of RV and new data indicator (NDI) information.

Abstract: An example method may include a processing system of a cellular network having a processor receiving, from a mobile endpoint device, a measurement of a performance indicator, a location, and spatial orientation information, the measurement of the performance indicator based upon at least one wireless signal from a base station of the cellular network, and adjusting at least one aspect of the cellular network in response to the measurement of the performance indicator, the location, and the spatial orientation information. Another example method may include a processing system of a mobile endpoint device having a processor receiving a wireless signal from a base station of a cellular network, capturing a measurement of a performance indicator based upon the wireless signal, recording a location and spatial orientation information, and transmitting to the cellular network the measurement of the performance indicator, the location, and the spatial orientation information.

Abstract: A system facilitating forward-compatible receivers in wireless communications systems. In one example, the system can include: a processor; and a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, comprising: generating information according to a protocol for receipt by a mobile device, wherein the information is indicative of a defined behavior of the mobile device relative to whether the mobile device is to override a reserved resource allocation applicable to a physical resource, and wherein the reserved resource allocation is indicative of whether the mobile device is authorized to communicate via the physical resource; and transmitting the information to the mobile device.

Abstract: The described technology is generally directed towards indicating to a receiver (e.g., a user equipment) which antenna ports are assigned for channel state information reference signals (CSI-RS). The indicator can be sent as radio resource control configuration data and/or by physical layer signaling such as in downlink control information. The receiver computes CSI based on the assigned antenna port or ports, and the reported (e.g., joint) CSI helps avoid mismatched joint CSI used for scheduling when multiple transmit and receive points (TRPs) are communicating with the user equipment.

Abstract: A closed loop carrier sense multiple access multiuser request to send and clear to send handshaking system is provided to efficiently allocate licensed and unlicensed spectrum for a plurality of mobile devices and across different base stations and mobile network operators. A user equipment device can be connected to a base station device via a first frequency in licensed spectrum, and a second frequency in unlicensed spectrum. The air interface on the first frequency can then be used to coordinate physical and virtual carrier sensing on a second frequency among a plurality of user equipment devices. Moreover, carrier sensing results from a plurality of UEs can be reported a base station device via the first frequency in licensed spectrum. The base station device can then schedule multiple user multiple input, multiple output (MU-MIMO) transmissions to a plurality of UEs on the second frequency in unlicensed spectrum.
