    Abstract: Systems and methods that enable and provide compensation for phase noise when performing Channel State Information (CSI) measurements are disclosed. In some embodiments, a method of operation of a User Equipment 5 (UE) comprises determining that a reference signal associated with a CSI Reference Signal (CSI-RS) is present on two Orthogonal Frequency Division Multiplexing (OFDM) symbols onto which the CSI-RS is mapped. The reference signal is a reference signal that is present on OFDM symbols only when CSI-RS is present on the OFDM symbols. The method further comprises producing at 10 least one phase error estimate for the CSI-RS that is mapped onto at least one of the two OFDM symbols based on the reference signal, compensating for phase error on at least one of the two OFDM symbols based on the at least one phase error estimate, and generating and reporting CSI based on the CSI-RS after compensating for phase error.

    Abstract: This disclosure describes systems, methods, and devices related to transmit and receive training unit generation. A device may determine a multiple-input multiple-output (MIMO) frame comprising at least in part a training field, the training field comprising one or more training units, each training unit comprising one or more training subfields. The device may determine one or more Golay sequences associated with each of the one or more training units. The device may cause to send the MIMO frame using one or more spatial streams of one or more bonded communication channels to one or more first devices.

    Abstract: The method includes generating a preamble sequence at a transmitter, where the transmitter is capable of generating a first type of preamble sequence and a second type of preamble sequence. The transmitter transmits a request message to a receiver to request network resources, where the request message including the preamble sequence. The transmitter receives a feedback message from the receiver. The transmitter controls the network data traffic based on the feedback message. The method further includes receiving, a receiver, a signal from the transmitter, the signal including the preamble sequence. The receiver detects the preamble sequence within the signal, where the receiver is capable of detecting a first type of preamble sequence and a second type of preamble sequence. The receiver identifies a request message within the signal based on the detected preamble sequence, and controls the network data traffic based on the identified request message.
