TL;DR: An overview of the techniques being considered for LTE Release 10 (aka LTEAdvanced) is discussed, which includes bandwidth extension via carrier aggregation to support deployment bandwidths up to 100 MHz, downlink spatial multiplexing including single-cell multi-user multiple-input multiple-output transmission and coordinated multi point transmission, and heterogeneous networks with emphasis on Type 1 and Type 2 relays.

TL;DR: In this paper, a method and apparatus for pilot signal transmission is described, where the set of occupied pilot block sub-carriers at least changes at least once in a burst.

TL;DR: This paper compares three candidate large-scale propagation path loss models for use over the entire microwave and millimeter-wave (mmWave) radio spectrum and shows the CI model with a 1-m reference distance is suitable for outdoor environments, while the CIF model is more appropriate for indoor modeling.

TL;DR: In this paper, a method for communicating a plurality of data streams between a transmitting device with multiple transmit antennas and a receiving device, is disclosed, which comprises determining a set of power weighting, efficiently quantizing the power weightings, and providing the set of weightings the transmitting device, and an additional aspect of the invention is a means of determining the best codebook weights by combining the maximum power and maximum capacity criteria.

TL;DR: In this article, the authors compared three large-scale propagation path loss models for use over the entire microwave and millimeter-wave (mmWave) radio spectrum: the alpha-beta-gamma (ABG) model, the close-in (CI) free space reference distance model, and the CI model with a frequency-weighted path loss exponent (CIF).
