Abstract: Methods and apparatus for supporting adaptive resource negotiation between evolved node Bs (eNBs) for enhanced inter-cell interference coordination (eICIC) are provided. This resource negotiation may occur via a network backhaul between the eNBs or, in some cases, using over-the-air messages (OAMs). For certain aspects, a first eNB may propose its adaptive resource partitioning information (ARPI) to a second eNB, where the second eNB may accept or reject the proposed resource partitioning. If the second eNB accepts the proposed partitioning, the second eNB may schedule resources, such as subframes, based on the accepted partitioning.

Abstract: Techniques for performing interference management to support peer-to-peer (P2P) communication in a wide area network (WAN) are described. In an aspect, interference management may be performed in a coordinated manner for/by a set of server nodes, which may include a P2P server and at least one neighbor server node of the P2P server. The P2P server may be a UE communicating peer-to-peer with at least one other UE or P2P client. Interference management may be performed for the set of server nodes to reduce interference to the P2P server and/or the at least one P2P client. In one design, active sets may be determined for UEs. The active set of each UE may include nodes received with sufficient strength by that UE. The set of server nodes may be determined based on the active sets of the P2P server, the at least one P2P client, and possibly other UEs.

Abstract: Techniques for reporting channel state information (CSI) based on scalable channel feedback are described. A user equipment (UE) may receive data transmission from one or more cells among a plurality of cells and may report CSI for each of the plurality of cells. For scalable channel feedback, the UE may report CSI with different granularity for different cells. The granularity of feedback for each cell may be selected based on the quality of a communication channel between the cell and the UE, which may be determined based on a long-term channel gain for the cell. The granularity of feedback may be defined by a subband size, a reporting interval, granularity of quantization of CSI, etc. The UE may report CSI for each cell based on the granularity of feedback for the cell. The UE may receive data transmission sent by at least one cell based on the reported CSI.

Abstract: Providing for a multipoint equalization (MPE) framework for coordinated multipoint (CoMP) transmission in wireless communication is described herein. The disclosed MPE framework involves distributed scheduling decisions for CoMP transmission, reducing complexity of scheduling coordination as compared with centralized scheduling techniques that coordinate scheduling decisions for multiple network base stations. Further, the MPE framework involves distributed computation of CoMP transmission coefficients, relying on a maximum of two backhaul hops to obtain information for the computation, and disseminate the transmission coefficients. The disclosed MPE framework shows substantial gains in various network deployments over conventional CoMP techniques.

Abstract: Methods, apparatuses, and computer program products are disclosed that facilitate an early decoding of relay signals. A relay receives a signal within a sub-frame from a network. A first and second reference symbol is detected within the sub-frame such that the first reference symbol is detected before the second reference symbol. The signal is then decode based on the first reference symbol.

Abstract: Techniques for scheduling UEs are described. In one design, a scheduler (e.g., for a cell) may receive channel direction information (CDI) and channel strength information (CSI) from a plurality of UEs. In one design, the CDI from each UE may include at least one eigenvector, and the CSI from each UE may include at least one singular value corresponding to the at least one eigenvector. The scheduler may schedule at least one UE among the plurality of UEs for data transmission based on the CDI and CSI from the plurality of UEs. The scheduler may select the at least one UE based on a metric related to signal-to-leakage ratio (SLR), or spectral efficiency, etc. In one design, the scheduler may evaluate the performance of different sets of UEs to determine whether to schedule one UE for single-user MIMO or multiple UEs for multi-user MIMO.
