Abstract: In one embodiment, an access point is configured with a plurality of resource units (RUs). Each RU is configured to use a frequency range that differs from frequency ranges used by the other RUs. The access point determines a pattern of recurring signal performance over time. For each RU of the plurality of RUs, the pattern indicates the recurring signal performance with respect to a station when the station is located in a given physical location. The access point allocates one or more of the RUs for communicating with the station. The pattern is used for avoiding allocation of any of the RUs for which the station is predicted to experience strong multipath fading or other destructive interference.

Abstract: A method for receiving broadcast information in an OFDM communication system may comprise receiving, by a mobile station, a periodically broadcast scheduling message from a base station. The periodically broadcast scheduling message may be an OFDM signal which indicates for each type of a plurality of types of broadcast information included in broadcast information, a pattern of frames to monitor for the type of broadcast information. The periodically broadcast scheduling message may also indicate a length of time to monitor. The method may further comprise monitoring and receiving, by the mobile station, information for at least one of the plurality of types of broadcast information, based on the periodically broadcast scheduling message.

Abstract: Malformed VLAN packets can be detected by programming suitable rules in a TCAM in the packet processing pipeline. In some deployments, for example, the TCAM rule(s) can match on the parsed EtherType metadata. More specifically, the match can be based on the EtherType metadata being set to a value equal to known VLAN TPIDs, such as 0x8100, 0x88a8, rather than being set to a standard EtherType.

Abstract: One or more bits of the destination MAC address indicate a number of times a reset event has occurred. These bits may be referred to as a generation number. The generation number in a destination MAC address is updated when a reset event occurs. In this way, frames issued by the sender prior to the reset may be distinguished from frames issued after the reset, since the destination MAC addresses in those frames will not match. In this way, the recipient device is protected from stale packets.

Abstract: A method for multiple access point (AP) transmission is disclosed. The method comprises receiving a repetition beacon from each of a plurality of APs, each received repetition beacon comprising a common information part and an AP-specific information part; decoding at least a subset of the received common information parts to obtain a first parameter; decoding the received AP-specific information parts to obtain a second parameter for each of the plurality of APs; performing a calculation based on the first parameter, the obtained second parameters and a number of the plurality of APs to obtain a calculation result; and transmitting a feedback based on the calculation result to the plurality of AP.

Abstract: Systems, methods, and devices for sidelink transmit-receive distance related determinations are disclosed herein. In one example, a wireless transmit receive unit (WTRU) may be configured with an associate between range information and zone configuration. The WTRU receive an indication of a specific range information requirement and determine its own zone location based on the configured information and location means (e.g., GPS). The WTRU may also receive zone location information of a transmitting device, and determine the distance between the WTRU and the transmitting device.

Abstract: This disclosure provides methods, devices and systems for wireless roaming. Some implementations more specifically relate to roaming candidate selection based on overlapping basic service set (OBSS) detection. In some aspects, a wireless station (STA) may identify one or more OBSSs based on wireless communications detected during an OBSS detection period and may roam to a new access point (AP) based on the identified OBSSs when a roaming condition is satisfied. In some implementations, the STA may store information associated with each identified OBSS in an OBSS table. When the roaming condition is satisfied, the STA may listen for beacon or probe response frames from other APs operating on its current wireless channel. If the STA receives beacon or probe response frames from one or more APs that match the OBSS table, the STA may roam to the matching AP with the highest candidate score.

Abstract: In one embodiment, Ethernet Virtual Private Network (EVPN) is implemented using Internet Protocol Version 6 (IPv6) Segment Routing (SRv6) underlay network and SRv6-enhanced Border Gateway Protocol (BGP) signaling. A particular route associated with a particular Internet Protocol Version 6 (IPv6) Segment Routing (SRv6) Segment Identifier (SID) is advertised in a particular route advertisement message of a routing protocol (e.g., BGP). The SID includes encoding representing a particular Ethernet Virtual Private Network (EVPN) Layer 2 (L2) flooding Segment Routing end function of the particular router and a particular Ethernet Segment Identifier (ESI), with the particular SID including a routable prefix to the particular router. The particular router receives a particular packet including the particular SID; and in response, the particular router performs the particular EVPN end function on the particular packet.

Abstract: A command can be received (910) from a network entity. The command can initiate a random access procedure and can include information of a type of random access procedure. The type of random access procedure can be selected from a 2-step random access procedure and a 4-step random access procedure. A MsgA transmission can be transmitted (920) in response to receiving the command when the type of random access procedure is the 2-step random access procedure.

Abstract: Techniques are disclosed for scalable virtualization of tenants and subtenants on a virtualized computing infrastructure. In one example, a first controller for the virtualized computing infrastructure configures underlay network segments in the virtualized computing infrastructure by configuring respective Virtual Extensible Local Area Network (VXLAN) segments of a plurality of VXLAN segments of a VXLAN in a switch fabric comprising network switches. Each VXLAN segment provides underlay network connectivity among a different subset of host computing devices of the virtualized computing infrastructure to enable orchestration of multiple tenants in the VXLAN. A second controller for a first subset of the host computing devices has underlay network connectivity through operation of a first VXLAN segment. The second controller configures overlay networks in the first subset of the host computing devices to enable orchestration of multiple subtenants in the first subset of the host computing devices.

Abstract: Some embodiments provide techniques for optimized programming of forwarding data in network device hardware. An operating system executing on the network device receives information associated with a network topology of a network(s) to which the network device belongs. Based on this information, the operating system can generate various data structures that facilitate the routing and forwarding of data through the network device. Based on the generated data structures, the operating system may then program hardware resources in the network device in order to implement routing and forwarding operations stored in the data structures. During generation of the data structures, the operating system may perform some operations to optimize the programing of the hardware resources in a manner that reduces the amount of hardware resources that would otherwise be used without such optimizations.

Abstract: An access node transmits, in a downlink signal having a series of subframes, a beam-formed reference signal in subframes, where the beam-formed reference signals are transmitted in fewer than all of the subframes of the downlink signal. A first subset includes beam-formed reference signals corresponding to a first frequency or first localized range of frequencies, and a second subset includes beam-formed reference signals corresponding to a second frequency or second localized range of frequencies. The second frequency or second localized range of frequencies is spaced apart from and differing from the first frequency or first localized range of frequencies. A user equipment, UE, receives, in the downlink signal, the beam-formed reference signal in each of a plurality of subframes. The UE performs mobility management measurements using at least the first subset of the received beam-formed reference signals and performs RLM using the second subset of the received beam-formed reference signals.
