Abstract: A method may include determining an uplink loss metric for an uplink communication path from a user equipment to a base station in a wireless network based at least on an uplink transmit beam for the user equipment and an uplink receive beam for the base station; determining a downlink loss metric for the downlink communication path from the base station to the user equipment based at least on a downlink transmit beam for the base station and a downlink receive beam for the user equipment; and determining, based on the uplink loss metric and the downlink loss metric, an uplink/downlink beam correspondence misalignment for the user equipment that indicates that the uplink transmit beam for the user equipment is misaligned with the downlink receive beam for the user equipment. For example, see FIGS. 5-6.

Abstract: The disclosure presents a method and system for enabling the monitoring of more than one propagation link (PL) between two transceivers, such as a fifth-generation (5G) broadband cellular base station (gNB) and user equipment (UE). The PL can represent a radiation pattern emitted by a MIMO antenna port. The monitoring can capture and record PL quality parameters and associate them to a PL index (PLI). The process can periodically cycle through the set of available PLs and select a best fit PLI configuration. The best fit PLI can be one that satisfies a link quality threshold and PL efficiency thresholds. The selected PLI can be communicated to both transceivers using parameter containers added to conventional control signals. Data messages communicated between the transceivers can utilize the selected best fit PLI configuration.

Abstract: A method includes determining, by an access point device, whether a channel is clear. The channel includes an unlicensed carrier. The method also includes sending an omnidirectional request-to-send transmission containing a beam identifier that the access point device will use for transmitting data; and receiving a clear-to-send message in response to the request-to-send message. In response to receiving the clear-to-send message, the method includes performing directional transmission of data using the beam identified in the request-to-send transmission.
