Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, one or more downlink grants scheduling one or more corresponding downlink transmissions from the base station to the UE. In some examples, the UE may enter a state of sleep prior to receiving the one or more downlink transmissions. In such examples, the UE may wake up from the state of sleep at a first time that is at least a threshold period of time before a second time corresponding to a beginning of the one or more downlink transmissions. After waking up from the state of sleep, the UE may activate a notch filter and use the activated notch filter to filter a spur generated at the UE. The UE may receive the one or more downlink transmissions with improved reliability based on activating the notch filter.

Abstract: A radio node that dynamically exchanges information specifying available spectrum in a shared-license-access band of frequencies is described. During operation, the radio node may provide a first grant request to a computer, where the first grant request includes a request to reserve a first portion of the shared-license-access band of frequencies for use by the radio node.

When the grant response indicates that the first grant request is denied, the radio node may provide to a second radio node a first notification that the request for a first portion of the shared-license-access band of frequencies was rejected. Similarly, the radio node may receive from the second radio node a second notification that a request for a second portion of the shared-license-access band of frequencies was rejected.

Abstract: A scheduling method applied in an industrial heterogeneous network in which a TSN and a non-TSN are interconnected is provided. The TSSDN controller classifies data flows according to the delay requirements, and calculates the scheduling priorities of the data flows in the industrial heterogeneous network. The TSSDN controller adopts an improved CSPF algorithm to determine a shortest path in the heterogeneous network, and marks the scheduling priorities of the data flows which are transmitted from the subnet of the heterogeneous network and arrive at the switch for the first time. Flow table matching is performed at the SDN switch. In a case of performing flow table matching successfully, the counter is updated and the instruction included in the flow table is executed. In a case of performing flow table matching unsuccessfully, a PacketIn message is transmitted to the TSSDN controller, and the TSSDN controller performs analysis and makes a decision.

Abstract: A wireless access node serves slice-capable User Equipment (UEs) and slice-incapable UEs. In the wireless access node, a radio exchanges slice data between the slice-capable UEs and a Baseband Unit (BBU). The radio exchanges non-slice data between the slice-incapable UEs and the BBU. The BBU exchanges the slice data with a wireless network slice and exchanges the non-slice data with a network element. The BBU determines its load for the slice-capable UEs. The BBU controls access to the wireless access node by new slice-incapable UEs based on the load for the slice-capable UEs.

The TAB node may then indicate bonus PDB at a next-hop node or request additional PDB from the next-hop node.

Abstract: Technologies are provided for detecting backup network paths in a computer network using geospatial data. Geospatial data for network links in a computer network can be used to identify network links that are located within a specified distance to one another. Network links located within the specified distance to one another can be considered to share the same or similar risks of failure. Network links located within the specified distance to one another can be included in shared risk resource groups (SRRGs), such as shared risk link groups (SRLGs). The SRRGs can be used to identify a backup path for a network path that does not include any network links that are in SRRGs that also contain network links in the network path. The backup path can be used to transmit data if a failure is detected in one or more links in the network path.
