摘要： Systems and methods are described for mapping Virtual Radio Instances (VRIs) into physical volumes of coherence in a Multiple Antenna System (MAS) with Multi-User (MU) transmissions ("MU-MAS"). These mapping methods enable communications through simultaneous non-interfering data streams in the same frequency band between the MU-MAS and multiple users, within their own volume of coherence. As the users move, their VRIs follow their respective volumes of coherence via teleportation to adjacent MU-MAS networks, thereby eliminating the need for handoffs as in conventional cellular systems and unnecessary control data overhead.

摘要： A system and method are described for compensating for frequency and phase offsets in a multiple antenna system (MAS) with multiuser (MU) transmissions ("MU-MAS"). The method may include transmitting a training signal from each antenna of a base station to one of a plurality of wireless client devices, generating frequency offset compensation data, receiving the frequency offset compensation data at the base station, computing MU-MAS precoder weights based on the frequency offset compensation data to precancel the frequency offset at the transmitter, and computing a plurality of MU-MAS precoder weights based on channel characterization data.

摘要： Systems and methods are described for coordinating transmissions in distributed wireless systems via user clustering. For example, a method according to one embodiment of the invention comprises: measuring link quality between a target user and a plurality of distributed-input distributed-output (DIDO) distributed antennas of base transceiver stations (BTSs); using the link quality measurements to define a user cluster; measuring channel state information (CSI) between each user and each DIDO antenna within a defined user cluster; and precoding data transmissions between each DIDO antenna and each user within the user cluster based on the measured CSI.
