摘要： An apparatus, method and computer program is disclosed. The apparatus may comprise means for providing information associated with an illumination signal, transmitted by an illuminator, back-scatted from a tag and received by an antenna of the illuminator using a first linear polarization configuration. The apparatus may also comprise means for determining that a different antenna polarization is required at the illuminator for the tag. The apparatus may also comprise means for configuring the antenna of the illuminator to use a different one of a plurality of linear polarization configurations for the tag.

摘要： In a wireless transmitter having a plurality of spatial streams differentiable at a receiver, wherein data is encoded and transmitted over a communication channel with pilot tones to provide the receiver with information about the effects of the communication channel and/or transmitter impairments and/or receiver impairments on the spatial streams transmitted, the benefits can be provided by identifying a plurality of symbol periods within which symbols representing some of the encoded data are to be transmitted, identifying pilot tone values for the plurality of symbol periods, wherein the identified pilot tone values are such that the receiver, when receiving at least some of the pilot tones having the identified pilot tone values, is provided with signals enabling the receiver to characterize the communication channel and/or transmitter impairments and/or receiver impairments to obtain transmit stream diversity gain, and transmitting the symbols and the pilot tones over the plurality of spatial streams for the plurality of symbol periods. In some embodiments, the pilot tones are orthogonal over space and time or over space and time and frequency, while in others they are semi-orthogonal. Pilot tone values might be of a constant amplitude and phase shifted, or might also have amplitude variations wherein at least two pilot tones are nonzero for spatial streams for a given symbol period.

摘要： A base station device includes a frame generator that generates a first training frame used for receive beam training among frames used for beamforming training, a beam controller that sets a beam used to transmit the first training frame to an omnidirectional beam, a transmitter that transmits the first training frame at the lowest MCS rate defined in IEEE 802.11, a receiver that receives a first response frame and a second response frame from a wireless terminal device that has received the first training frame after a determined period since transmission of the first training frame, and a frame determiner that determines whether the received first response frame is a response to the receive beam training. In a case where the received first response frame is a response to the receive beam training, the beam controller sets a beam received by the receiver to a directional beam, and the receiver receives the second response frame by using the directional beam.
