摘要： Techniques for transmitting pilot and for processing received pilot to obtain channel and interference estimates are described. A terminal may generate pilot symbols for a first cluster in a time frequency block based on a first sequence and may generate pilot symbols for a second cluster in the time frequency block based on a second sequence. The first and second sequences may include common elements arranged in different orders and may be considered as different versions of a single sequence. The terminal may transmit the pilot symbols in their respective clusters. A base station may obtain received pilot symbols from multiple clusters in the time frequency block. The base station may form each of multiple basis vectors with multiple versions of the sequence assigned to the terminal and may process the received pilot symbols with the multiple basis vectors to obtain a channel estimate for the terminal.

摘要： Techniques for reporting channel state information (CSI) 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. In an aspect, the UE may generate CSI with different quantization granularity (e.g., different codebook sizes), or different frequency granularity (e.g., different subband sizes), and/or different time granularity (e.g., different reporting intervals) for different cells based on the performance impact of each cell for data transmission to the UE. The performance impact of each cell may be determined based on a long-term channel gain or received power of the cell at the UE. The UE may quantize the CSI for each cell based on the codebook size for the cell. The UE may generate the CSI for each cell based on the subband size and/or the reporting interval for the cell.

摘要： 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.

摘要： Providing for resource-specific interference reporting to facilitate short-term channel quality and transmission parameterization in wireless communications is provided herein. By way of example, a UE observing high interference can utilize reference signals of a second UE (e.g., that observes less interference) for short-term channel quality measurements. These measurements can be on an order of one or two signal subframes, or less, to reflect interference resulting from distinct scheduling decisions of an interfering transmitter. Based on the short-term channel quality measurements, a base station serving the UE can initiate detailed interference mitigation, perform scheduling decisions that compensate for distinct parameterization of the interfering cell, or the like. This can result in improved wireless communications even for UEs observing very high wireless interference.

摘要： Systems and methodologies are described that facilitate sending and/or receiving user equipment specific reference signals (UE-RSs) in a wireless communication environment. A UE-RS pattern can be selected, yielded, etc. based upon a number of symbols from a subframe utilized for downlink transmission. At least one time domain component of the UE-RS pattern can vary based upon the number of symbols from the subframe utilized for the downlink transmission. For instance, the at least one time domain component can be punctured, time-shifted, and so forth. Further, UE-RSs can be mapped to resource elements of the subframe as a function of the UE-RS pattern. Moreover, a UE can utilize the UE-RS pattern to detect UE-RSs on the resource elements of the subframe. Further, the UE can estimate a channel based upon the UE-RSs.
