Abstract: An apparatus and method for managing interference in a transmission medium are disclosed. A apparatus and method may be used to detect a condition experienced by only one of first and second wireless nodes, and modify an operational parameter of one of the first and second wireless nodes, if the condition is detected, such that both the first and second wireless nodes experience the condition or neither the first and second wireless nodes experience the condition.

Abstract: Systems, methods, and devices for detecting packets in signals are described herein. The apparatus comprises a receiver configured to receive a signal comprising a plurality of samples. The apparatus comprises circuitry. The circuitry is configured to apply a match filter to the plurality of samples to produce a plurality of blocks of samples, each block comprising a number of samples. The circuitry is configured to correlate a subset of the samples of a first block with a subset of the samples of a second block to produce an output. The circuitry is configured to compare the output to a threshold value to determine whether the signal comprises a data packet.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for efficiently managing groups of stations (STAs) receiving simultaneous transmissions in a multiuser multiple-input multiple-output (MU-MIMO) scheme. One example method generally includes; for a first apparatus in a number of groups of apparatuses, allocating a first spatial stream position for each of at least one first group in the number of the groups; and transmitting a first unicast message to the first apparatus, wherein the first unicast message comprises an indication of the allocated spatial stream position for each of the at least one first group and, for each group in the number of the groups, an indication of a membership status, in the group, of the first apparatus.
