Abstract: In one embodiment, a device in a network receives data regarding traffic volumes of deterministic and non-deterministic traffic along a first path in the network. The device predicts, using the received data, an increase in the traffic volume of the non-deterministic traffic along the first path in the network.

Abstract: Sounding reference signal (SRS) transmission with implied request-to-send (RTS)/clear-to-send (CTS) operations is discussed. Two different types of SRS are defined, a legacy SRS associated with channel measurement sounding, and a contention SRS associated with contention resolution for medium sharing. The type of SRS may be distinguished based on the SRS resource associated with the particular type. Thus, legacy SRS are assigned to one SRS resource, while contention SRS are assigned to separate SRS resources. Therefore, when a neighbor node detects an SRS associated with the SRS resource for contention-type SRS, the neighbor node may know to refrain from transmission or to adjust or modify its communications depending on a spatial direction of the contention SRS.
