摘要:
Embodiments of a multicarrier receiver with interference-aware demodulation and methods for channel estimation using recursive filtering in wireless networks are generally described herein. Other embodiments may be described and claimed. In some embodiments, orders of a recursive filter are allocated to track a main channel and one or more interfering channels to generate channel estimates.

Embodiments of an enhanced Node-B (eNB) configured to operate as a serving eNB in a coordinated multi-point (CoMP) communication network and method are generally described herein. The serving eNB precodes signals for transmission to user equipment (UE) using a precoding matrix that is selected based on a reference PMI for a beamformed transmission in accordance with a modulation and coding scheme (MCS) that is selected from a modified CQI. When operating in coordination mode, on more cooperating eNBs are configured to suppress interference to the UE using coordination PMIs during the resource block allocated for the beamformed transmission.
摘要:
A noise and interference estimator and method for estimating noise and interference in a coordinated multipoint (CoMP) system at a mobile communication device is disclosed. The method comprises the operation of receiving a channel state information reference signal (CSI-RS) from a serving transmitting station at a user equipment (UE). Resource elements (REs) occupied by the CSI-RS of the serving transmitting station are muted on cooperating transmitting stations in the CoMP system. The operation of estimating a non-cooperating interference noise covariance matrix from the CSI-RS transmitted by the serving transmitting station follows.

Embodiments of the present disclosure describe devices, methods, computer-readable media and systems configurations for communication of channel state information among network entities. In various embodiments, may calculate first-, second- and third-stage channel state information for nodes of a coordinated multipoint measurement set. Other embodiments may be described and/or claimed.
摘要:
Briefly, in accordance with one or more embodiments, mobile station or user equipment receives pilot signals from two or more infrastructure nodes in a distributed antenna system, and calculates phase or timing information, or combinations thereof, from the pilot signals. The mobile station feeds back the phase or timing information, or combinations thereof, to the infrastructure nodes, and then receives one or more subsequent transmissions from the infrastructure nodes with phase shift or timing adjustments, or combinations thereof, calculated by the infrastructure nodes and applied to the spatial streams transmitted by the infrastructure nodes.
