Abstract: Controlling and reducing overhead in control channels in 5G or other next generation communication systems is provided herein. In connection with a data transmission between a device and a network node device, an overhead management component (OMC) can analyze one or more factors associated with the device, including speed or Doppler metric(s) of the device, type of service associated with the device, historical HARQ statistics for the device, configured threshold value for CSI estimation, device capability regarding redundancy version support, or another factor(s). Based on analysis results, OMC can determine whether to utilize a single redundancy version state or a multiple redundancy versions state. If the single redundancy version state is selected, OMC can generate control information that does not include redundancy version information, the control information being communicated via a control channel OMC can communicate RRC signal to the device to indicate the determined redundancy version state.

Abstract: The technologies described herein are generally directed toward communicating determined contention levels of resource pools to UEs enabling the UEs to select from available resource pools. 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 assigning determined contention levels to respective ones of a group of resource pools. The operations can further include communicating, to a user equipment device, the determined contention levels, enabling the user equipment device to select a resource pool of the group of resource pools based on the determined contention levels.

Abstract: Aspects of the subject disclosure may include, for example, receiving a radio frequency (RF) signal having a carrier wave component that operates at a carrier frequency within a millimeter wave spectrum. The RF signal also includes an information component based on a phase shift keying (PSK) modulation of the carrier wave component. A local oscillator (LO) signal is obtained, which includes an LO frequency that approximates the carrier frequency. The received RF signal and the LO signal are combined without using signal multiplication to obtain a first combined output signal. The first combined output signal being detected via a non-linear energy detector to obtain a first detected signal. The first output signal includes information of the information component. Other embodiments are disclosed.

Abstract: 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 generating a first signal in an initial domain and transforming the first signal into a first portion of a time-frequency grid of a time-frequency domain, resulting in a transformed first signal. The operations further include combining the transformed first signal with a second signal of a second portion of the time-frequency grid, resulting in a combined signal, and transmitting the combined signal to a user equipment device for a further transformation. The operations further include receiving a response signal from the user equipment device that was configured, based on the further transformed first signal.

Abstract: Various embodiments disclosed that describe systems to facilitate paging an idle subscriber identity module using a connected subscriber identity module operating in a single radio configuration. According to some embodiments, a system can comprise receiving a paging request that is designated for a first device of a communication device, wherein the communication device comprises the first device and a second device; determining whether the second device is in an active state; and in response to the determining that the second device is in the active state, transmitting a message to second device indicating that the paging message was received for the first device.

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 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.
