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: This paper provides an overview of carrier aggregation and discusses major technical issues including aggregation structure, scenarios, implementation, control signalling design and coexistence with legacy LTE systems.

TL;DR: This paper proposes a tractable baseline multicast D2D model, and uses it to analyze important multicast metrics like the coverage probability, mean number of covered receivers and throughput, and examines how the multicast performance would be affected by certain factors like dynamics and network assistance.

TL;DR: In this article, a communication system provides downlink acknowledgments corresponding to uplink transmission using hybrid automatic repeat request to multiple users in an Orthogonal Frequency Division Multiplexing communication system, wherein a frequency bandwidth comprises multiple frequency sub-carriers, by spreading each acknowledgment of multiple acknowledgments with a selected spreading sequence of multiple spreading sequences to produce multiple spread acknowledgments, wherein each acknowledgment is intended for a different user of the multiple users, and distributing the multiple spread acknowledgment across the multiple subcarriers.

TL;DR: In this article, power control for LTE transmissions in unlicensed bands is discussed, where a first device (such as a LTE UE or LTE eNB) determines a scheduled transmission window for a LTE transmission in an unlicensed band.
