摘要:
Various embodiments may be generally directed to full duplex (FDX) communications on a wireless channel. More specifically, in various embodiments described herein, FDX communications may occur on a wireless channel between a FDX capable device, such as an access point (AP), and two or more half-duplex (HDX) capable devices, such as a plurality of stations (STAs). For instance, the AP may transmit information to a first station (STA) via a wireless channel at the same time as receiving information from a second STA via the wireless channel. In some embodiments, the AP may arrange the FDX communications.
摘要:
A simultaneous transmit and receive technology is described. A downlink transmission and an uplink receive beam are formed at a base station (BS) having a beam pattern with predetermined nulls. The predetermined nulls are formed over predetermined elevation angles to reduce interference with a proximate BS. Transmission and reception occur simultaneously using the beam pattern from the BS.

An embodiment of the present invention provides a method of using differential precoding feedback for correlated channels, comprising, transmitting by a mobile station (MS) as feedback an index angle for a differential discrete Fourier transform (DFT) codeword corresponding to a shift of a dominant beam represented by a base codeword, where the feedback corresponds to a precoding vector V(t)=Q({circumflex over (θ)}) for index angle θ, where Q ( θ ^ ) = [ 1 j 2 π m / 32 j 4 π m / 32 j 6 π m / 32 ] and m=−16 cos({circumflex over (θ)}).

摘要:
A method is disclosed to eliminate inter-cluster interference of user equipment located at the edge of a cluster of cells. The method operates by employing fractional frequency reuse (FFR) principles on clusters or combinations of cells in a wireless neighborhood, in which base stations in the cells coordinate their operations in a scheme known as coordinated multi-point transmission (CoMP). By using the FFR principles to single out edge users of the CoMP cluster, the method mitigates interference and increases throughput for the edge users.

Techniques are described that provide uplink power control techniques that can support different uplink multi-input multi-output (MIMO) transmission schemes. Open and closed loop power control schemes can be used to prescribe the power level of the mobile station.
