An example access point may include a memory and a processor executing instructions from the memory to receive an instruction to start a scan on a different wireless communication channel than an operating channel of the access point; transmit a Clear To Send-to-self frame on the operating channel of the access point, to notify client devices associated with the AP and at least a neighboring AP that the operating channel is busy, wherein the control frame includes a basic service set color associated with the access point; scan on the different wireless communication channel subsequent to transmitting the Clear To Send-to-self frame; and defer a subsequent data transmission received from the client devices in response to the data transmission including the basic service set color associated with the access point.

The present invention relates to a wireless communication system. More specifically, the present invention relates to a method and a device for determining number of retransmissions of sidelink data in wireless communication system, the method comprising: determining number of retransmissions of sidelink data when the sidelink data is available for transmission; transmitting the sidelink data via direct interface between UEs; and retransmitting the sidelink data as many as the determined number of retransmissions.

A data communication system controls Software Defined Network (SDN) Virtual Network Functions (VNFs). A Network Function Virtualization Infrastructure (NFVI) executes the SDN VNFs and responsively transfers SDN Key Performance Indicators (KPIs) to a Management and Orchestration (MANO) computer. The MANO computer processes the SDN KPIs from the NFVI to determine an NFVI task to perform for the SDN VNFs. The NFVI task comprises at least one of: SDN VNF relocation, SDN VNF off-boarding, SDN VNF darkening, SDN VNF lightening, and SDN VNF on-boarding. The MANO computer transfers NFVI control data indicating the NFVI task to the NFVI. The NFVI performs the NFVI task for the SDN VNFs responsive to the NFV control data.

This disclosure relates to orthogonal frequency division multiple access (OFDMA) communication in wireless local area networks (WLANs). According to some embodiments, a downlink OFDMA frame may be transmitted. An uplink OFDMA frame including acknowledgements associated with the downlink OFDMA frame may be received. The uplink OFDMA frame may be processed, in some instances including determining which devices receiving the downlink OFDMA frame transmitted an acknowledgement associated with the downlink OFDMA frame in the uplink OFDMA frame.

Provided is a method and device for switching a primary/backup PW. When a primary PW is detected having changed into a Down status by a BFD session corresponding to the primary PW, PE searches for a matching switching information entry. When in the switching information entry indicates transmission switching is supported, and Failover value indicates that a packet is forwarded via a backup PW, the PE updates Failover value in a hardware protection switching entry to the Failover value in the switching information entry. When bRX in the switching information entry indicates reception switching is supported, the PE updates drop identifier in a hardware reception entry to a value indicating that a packet is received, and updates the bFS to a value indicating that transmission switching is not supported; and the PE reports a Down event of the primary PW.

In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may determine a plurality of TCP ACKs, and at least one of TCP data or UDP data for a multi-user transmission to a set of STAs. The apparatus may allocate the plurality of TCP ACKs to a PPDU before allocating the at least one of the TCP data and the UDP data to the PPDU. In certain aspects, the plurality of TCP ACKs may be frequency division multiplexed in the PPDU. In certain other aspects, the apparatus may transmit, to the set of STAs, the multi-user transmission including at least the plurality of frequency division multiplexed TCP ACKs.

A matrix-array sensor comprises a matrix of detection elements arranged in rows and columns and a readout circuit for each column, the elements of one and the same column linked to the corresponding readout circuit via a bus, each element comprising a sensor, a charge integrator configured to accumulate charge generated by the sensor, a comparator configured to generate a trigger signal when a voltage level across the terminals of this comparator reaches a threshold level, and a bus access logic circuit which is configured to receive, as input, the trigger signal and to attempt to transmit, over the bus, an address of the element in the column, wherein the elements of one and the same column have predetermined bus access priority levels, and wherein the bus access logic circuit of each element is configured: to abandon transmission of the address and reset the charge integrator of the detection element if the bus is pre-empted by an element having a higher priority level; to count the number of attempts made before being able to transmit the address; and to communicate the number to the readout circuit along with the address of the element.
