Abstract: Aspects of the subject disclosure may include, for example, obtaining a received channel-encoded data block having information bits, a transmitted error-check value, and redundant code bits. The redundant code bits correspond to a channel code applied to the received channel-encoded data block prior to transmission via a communication channel. A channel code type is identified and responsive to it being systematic, the information bits and the transmitted error-check value are obtained without decoding according to the channel code. The received channel-encoded data block is checked according to the transmitted error-check value to obtain a result. Responsive to the result not indicating an error, extracting the information bits without decoding the received channel-encoded data block according to the channel code. Responsive to the result indicating an error, decoding the received channel-encoded data block according to the channel code to obtain decoded information bits. Other embodiments are disclosed.

Abstract: Methods, computer-readable media, and apparatuses for presenting a visualization of at least one wireless channel parameter as an overlay on top of an image of an environment are described. For example, a processing system including at least one processor may obtain at least a first wireless channel parameter of at least a first location, generate a first visualization of the at least the first wireless channel parameter, where the first visualization indicates at least one of: a magnitude of the at least the first wireless channel parameter or a direction of the at least the first wireless channel parameter, and present the first visualization of the at least the first wireless channel parameter as an overlay on top of a first image of an environment associated with the first location via a display device.

Abstract: An example method may include a processing system of a base station having a processor selecting a blank resource of a time and frequency resource grid of the base station for a transmission of a channel sounding waveform and transmitting the channel sounding waveform via the blank resource. Another example method may include a processing system of a channel sounding receiver receiving at a location, from a base station, a channel sounding waveform via a blank resource of a time and frequency resource grid of the base station, and measuring a channel property at the location based upon the channel sounding waveform.

Abstract: In one example, a processing system of a mobile channel sounding transmitter including at least one processor may establish a wireless side link between the mobile channel sounding transmitter and a channel sounding receiver, transmit, to the channel sounding receiver, a wireless synchronization signal via the wireless side link, and transmit at least one channel sounding waveform in accordance with the wireless synchronization signal. In another example, a processing system of a channel sounding receiver including at least one processor may establish a wireless side link between a mobile channel sounding transmitter and the channel sounding receiver, obtain, from the mobile channel sounding transmitter, a wireless synchronization signal via the wireless side link, and obtain, from the mobile channel sounding transmitter, at least one channel sounding waveform in accordance with the wireless synchronization signal.

Abstract: Aspects of the subject disclosure may include, for example, a base station that includes a phased array antenna system and a MIMO antenna system. The MIMO antenna system may receive sounding signals sent by user equipment (UE) and determine angular location information for each UE. The angular location information may be used by the phased array antenna system to create antenna beams. The angular location information may also be used to schedule communications with multiple UEs in common beams. Other embodiments are disclosed.

Abstract: Various embodiments disclosed herein provide for switching between non-orthogonal and orthogonal multiple access protocols dynamically. A base station device can determine whether a user equipment device on a communication link should use a non-orthogonal multiple access system or an orthogonal multiple access system based on one or more attributes of the communication link, and send an indication of the selection to the user equipment device. The base station device can indicate the selection using a spreading factor parameter that is either equal to one or greater than one. If the spreading factor parameter is equal to one, that can indicate to the user equipment device to use an orthogonal multiple access system, whereas if the spreading factor parameter is greater than one, that can indicate to the user equipment device to use a non-orthogonal multiple access system.
