Abstract: In an OFDM communication system (100), wherein a frequency bandwidth is divided into multiple Physical Resource Units (PRUs), a Frequency Partitioning Configuration Module (FPCM) (118) is provided that configures a physical layer for use in multiple coverage areas. The FPCM divides (504) the PRUs into a first group, for frequency selective allocations, and a second group, for frequency diverse allocations. The FPCM subdivides (506) each of the two groups into multiple sets of PRUs, maps (510) the sets of PRUs from the first group to consecutive PRUs allocated for contiguous segment allocation (CS-PRUs), and maps (512) the sets of PRUs from the second group to consecutive PRUs allocated for distributed segment allocation (DS-PRUs). The FPCM permutes (514) the DS-PRUs and allocates (518) the CS-PRUs and the permuted DS-PRUs to at least one frequency partition.

Abstract: The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for network management through a hierarchical architecture with a control functionality of a network server (e.g., C-SON) in relationship to clusters comprising eNBs (access points), and for implementing coordinated multi-point (CoMP) transmission and reception in conjunction with inter-cell interference coordination (ICIC) in wireless networks such as LTE wireless networks. In particular, embodiments of the invention describe control and coordination mechanisms among the network elements for different network architectures and use-case scenarios. Such mechanisms may be managed by a centralized self-organizing network controller such as C-SON and hierarchically via localized controllers (such as cluster coordinators) residing in macro eNBs depending on system architectural constraints and network state. A fault-tolerant mechanism then may be defined to recover from failure of controlling sub-elements so that the network remains stable at all times.

Abstract: Communication systems may employ transmission of feedback information and responses thereto, on a wireless connection such as a millimeter wave connection. The feedback information itself may be used to influence the beamforming or beam direction used for the transmission of the feedback information. A method can comprise determining a feedback indicator regarding reception of a transmitted waveform. The method can also comprise tailoring, for example beamforming, a signal for transmitting the feedback indicator based on a content of the feedback indicator.

Abstract: User equipment (UE), referred to herein as an interfering UE (130), can be detected that is proximate to a low-power cell (120), such as a micro-cell, pico-cell, femto-cell, a relay, or the like. The interfering UE (130) can be transmitting to the base station (110) at a power level that is producing high interference affecting uplink performance between a different UE and the low-power cell (120). A power adjustment message (140) can be generated at the base station (110). The power adjustment message (140) can be conveyed (156) from the base station (110) to the interfering UE (130). The power level adjustment message (130) can cause the interfering UE (130) to lower its transmission power (164), which reduces the high interference, thereby improving uplink performance between the different UE and the low-power cell (120).

Abstract: A method for blindly detecting a precoding matrix index used to transmit a data or control signal is provided. The method includes receiving at a mobile station (102) a common reference signal and user specific data and control signal weighted by precoding matrix. An objective function is applied to the received reference signal and user specific data and control signal that minimizes the objective function for each of at least one rank used to transmit the received user specific data and control signal and each of known possible modulation constellations used to transmit the received data/control signal to determine the precoding matrix index (PMI).
