Abstract: Certain aspects of the present disclosure relate to quasi co-location assumptions for aperiodic channel state information (CSI) reference signals (RS) in communications systems operating according to NR techniques. An exemplary method that may be performed by a UE includes determining a quasi-co-location (QCL) relationship of an aperiodic channel state information (CSI) reference signal (CSI-RS) to a physical channel and processing the aperiodic CSI-RS according to the determined QCL relationship.

Abstract: This disclosure presents several embodiments of a device configured to perform inband telemetry tracking. The device is configured to store a flow table that tracks metrics of a detected packet flow that passes through the device. More specifically, the flow table tracks several telemetry metrics, each telemetry metric being specific to a tracking time period, and tracking statics based only on packets of the packet flow that were received during that specific time period. At an end of an export time period (which is longer than a tracking time period), the device transmits all stored telemetry metrics from the flow table to a collector.

Abstract: A device may receive historical network behavior data associated with a network that includes network devices and may receive historical weather data associated with a geographical location of the network. The device may receive historical action data identifying historical actions taken for the network in response to the historical weather data, and may train a correlation model, with the historical network behavior data, the historical weather data, and the historical action data, to generate a trained correlation model. The device may receive a weather event forecast associated with the geographical location, and may process the weather event forecast, with the trained correlation model, to determine an anticipated behavior of the network in response to the weather event forecast. The device may process data identifying the anticipated behavior, with the trained correlation model, to identify actions to take in response to the anticipated behavior and may perform the actions.

An outbound interface identifier included in the MAC forwarding entry is an identifier of an interface connected to the CE device.

Abstract: A packet sending method includes: receiving, by a first node, a first broadcast data packet sent by a second node; and if a sequence number of the first broadcast data packet equals 1 plus a sequence number of a latest data packet saved by the first node, and the first node does not receive, within a first preset time period, a first acknowledgement indication for the first broadcast data packet of the second node, sending, by the first node, a first broadcast acknowledgement packet when the first preset time period elapses, where the first broadcast acknowledgement packet includes the first acknowledgement indication, and the first acknowledgement indication includes the sequence number of the first broadcast data packet and an address of the second node. This method could resolve acknowledgement packet implosion while ensuring broadcast packet reliability of a wireless mesh network.

Abstract: Methods, systems, and devices for wireless communications are described that provide for system information (SI) for access and backhaul. An access node (AN) may provide SI to devices within its cell indicating communication procedure configurations. The AN may provide SI to devices that is specific to whether the communication procedure is an access procedure or a backhaul procedure. The AN may transmit a common master information block (MIB) directing the devices within its cell to a search space in order to receive the remaining SI. The search space may be shared between access devices and backhaul devices or alternatively may be separate between access and backhaul devices. The remaining SI may not be shared between access and backhaul devices. The devices may determine different configurations as defined by the SI from the AN for communications procedures based on whether the procedure is an access procedure or a backhaul procedure.

Abstract: Methods, systems, and devices for wireless communications in millimeter wave (mmW) systems are described. A mmW wireless device may identify a plurality of subsets of antennas from available antennas. The wireless device may compare effective array gain values for each subset in the plurality of subsets of antennas. An effective array gain value may be determined based on a realized array gain for each subset normalized or penalized by a radio frequency (RF) power consumption for antennas corresponding to each subset in the plurality of subsets of antennas. Based on the comparison, the wireless device may select one or more subsets of the plurality of subsets of antennas, the selected one or more subsets may correspond to antenna combinations of one or more antenna subarray units. The mmW wireless device may then communicate using the selected one or more subsets.

Abstract: A vehicle is provided that includes Ethernet controllers that operate first electronic devices and perform communication using scalable service-oriented middleware on Ethernet/internet protocol (SOME/IP). An Ethernet switch generates a communication path between the Ethernet controllers and executes communication between the Ethernet controllers based on the generated path. A plurality of CAN controllers operate second electronic devices and perform CAN communication. A gateway then executes the CAN communication with the CAN controllers, executes communication with the Ethernet switch, and transmits CAN diagnostic information of the CAN controller to the Ethernet switch.

Abstract: Where large transport blocks are rate-matched and transmitted on each PUSCH segment using different redundancy versions (RVs), RV cycling with a small number of PUSCH segments might not cover the whole codeword, and/or rate-matching a large TBS across many PUSCH segments into the resource of a single PUSCH segment may lead to an effective coding rate of the self-decodable redundancy versions that is too high. To avoid these issues, the starting position of one or more RVs may be shifted by setting the starting position of a current RV to be the same as an ending position of a previous position, or by scaling the starting position by a value. Alternatively, these issues may be avoided by setting a new starting position for an RV based on the gap from the end of a previous RV to the start of a current RV.

Abstract: Aspects relate to reporting beam failure. Upon detecting a beam failure, a user equipment (UE) may transmit a beam failure recovery request to a base station. If the uplink is working, the UE may transmit the beam failure recovery request via uplink signaling (e.g., via a physical uplink control channel or a physical uplink shared channel). If the uplink is not working or if the beam failure is due to downlink quality degradation, the UE may transmit the beam failure recovery request via a random access channel (RACH) message.

Abstract: An enhanced LBT procedure (200) mitigates unnecessary delays in delivering transmissions between User Equipment and base stations over unlicensed spectrum. A UE or base station selects a particular CAPC corresponding to an intended transmission (225) based on an intelligent mapping of different types of transmission payload (e.g., transmission payload other than or in in addition to pre-defined, QoS-related UP message data payload) to different CAPCs. Most (if not all) of the mapped CAPCs corresponding to the different types of transmission payload are of a higher priority than a lowest priority CAPC (212-222), resulting in channel access procedures that are more commensurate with respective transmission payloads.
