Abstract: Systems, methods, and devices are disclosed for re-routing network traffic directed to a pod device. Traffic is routed from an ingress device towards a first node in communication with multiple pods. In response to the detection of a failure event associated with the first pod, a network device address of the first pod is removed from a routing table. If a packet is received from the ingress device that is destined for a service, the routing table is used to look up a pod for handling a service request associated with the service. A network device address of a second pod is determined based on not finding the network device address of the first pod in the routing table. The packet is then forwarded to the second pod using the second device address before the ingress device knows that the first pod has failed.

Abstract: A method and an apparatus for transmitting a PPDU in a WLAN system are proposed. Specifically, a transmitter generates a PPDU and transmits the PPDU to a receiver. The PPDU includes a legacy field and an EHT field. The legacy field includes a VHT-STF and a HE-STF. The EHT field includes an EHT-STF and a data field. The EHT field is configured on the basis of a CSD value of each transport chain. The CSD value is determined as a candidate CSD value in which the sum of a first absolute value and a second absolute value is the minimum on the basis of a power ratio. The power ratio is a ratio of a received power of the VHT-STF, the HE-STF, or the EHT-STF to a received power of the data field. The first absolute value is an absolute value of a value related to 5 percent of a CDF relative to the power ratio. The second absolute value is an absolute value of a value related to 95 percent of the CDF relative to the power ratio.

Abstract: A wireless device receives an uplink grant for consecutive subframes. The uplink grant indicates: a number of the consecutive subframes comprising a starting subframe and an ending subframe; and a hybrid automatic repeat request process number (HARQ ID). LBT(s) are performed for transmitting via the consecutive subframes. A packet is transmitted via a first subframe of the consecutive subframes according to a first HARQ ID. The first HARQ ID is equal to ((the HARQ ID plus i) modulo a first pre-configured number). i indicates a subframe position of the first subframe in the consecutive subframes. i is equal to zero for the starting subframe and i is equal to the number minus one for the ending subframe, regardless of an outcome of the LBT(s) for any subframe of the consecutive subframes before the first subframe.

Abstract: An uplink grant is received. The uplink grant comprises: a field indicating a number of consecutive uplink subframes; an assignment of resource blocks comprising subcarriers; and a power control command. A determination is made of a transmission power of transport blocks in each subframe of the consecutive uplink subframes based on the power control command. The transmission power in each subframe is adjusted based on a total transmit power in each subframe exceeding a power value in each subframe. Transport blocks are transmitted, using the transmission power, via the subcarriers across each of the consecutive uplink subframes.

Abstract: A first wireless communications device including a transmitter, such as a base station or UE, identifies a first traffic flow, e.g., a TCP packet flow, for which end to end packet retransmission is supported. The first wireless communications device transmits an explicit indication to a second wireless communications device to skip Hybrid Automatic Repeat Request (HARQ) feedback for data, corresponding to the first traffic flow, said data being transmitted to the second wireless communications device. The explicit indication to skip HARQ feedback for data is, e.g., one of: a HARQ Off Indicator in a Downlink Control Information (DCI) Scheduling message, a Semi-Persistent Scheduling HARQ Off Indicator, or a AUL HARQ Off Indicator. HARQ suppression is applied for the first traffic flow at a radio link layer and/or MAC layer.

Abstract: Various communication systems may benefit from appropriate indication of support for communication protocols. In particular, certain wireless systems that use handover may use selective proprietary protocol support indication removal. A method can include determining protocol support based on a first configuration received from the source access node. The method can also include determining whether to continue, after a handover, using a proprietary protocol based on whether a first configuration remains unchanged. The method can further include using or ceasing from using the proprietary protocol based on the determination.

Abstract: Systems, methods, and other embodiments associated with wake-on-frame mechanisms are described. According to one embodiment, an apparatus includes a central processing unit (CPU) that performs routing related processing on packets prior to sending the packets to one or more destination devices and a switch configured to send packets to the CPU. The switch is configured to, in response to receiving a new packet for the CPU, determine whether a wake-on-frame mechanism is enabled. When the wake-on-frame mechanism is enabled, the switch causes an interrupt signal to be sent to the CPU, such that receiving the interrupt signal will cause the CPU to wake up. When the wake-on-frame mechanism is disabled, the switch sends the packet to the CPU.

Abstract: Some embodiments provide a centralized overlay-network cloud gateway and a set of centralized services in a transit virtual private cloud (VPC) connected to multiple other compute VPCs hosting compute nodes (VMs, containers, etc.) that are part of (belong to) the overlay network. The centralized overlay-network cloud gateway provides connectivity between compute nodes of the overlay network (e.g., a logical network spanning multiple VPCs) and compute nodes in external networks. Some embodiments use the centralized overlay-network cloud gateway to provide transitive routing (e.g., routing through a transit VPC) in the absence of direct peering between source and destination VPCs. The overlay network, of some embodiments, uses the same subnetting and default gateway address for each compute node as the cloud provider network provided by the virtual private cloud provider.

Abstract: A connection between two UEs is identified by a single connection identifier. Different streams are transmitted over different wireless links with potential redundancy between streams. Initially a first WiFi link is used to communicate with the second UE. After the first UE decides it will handoff to a second WiFi AP it establishes a connection with a cellular AP and then communicates a second stream corresponding to the same connection. The first and second streams initially communicate the same content. The first WiFi link is terminated, but the second stream continues to communicate content. The first UE then establishes a second WiFi connection with a second WiFi AP and communicates a third content stream of the first connection to second UE via second WiFi link. The third stream initially communicates information also communicated over second stream. The cellular link is terminated. The second WiFi link is used to communicate content.
