20130336280 | Signaling of Precoding Vector Pattern in a Lean-Carrier System - In a system using spatial precoding, in the event that reliable channel state information is unavailable, a transmitting node uses an extended transmission mode, in which the precoders applied to data within each of several groups of time-frequency resources vary according to frequency. The extended transmission mode creates a frequency-selective variation in precoders, which may appear to be random, while using DMRS-based transmission. This variation is achieved by applying different precoders to the resource elements carrying data, using a pattern of precoder variation that is known to the receiving device. The precoding applied to DMRS within a given group of time-frequency resources is held constant—thus, the varying precoders within a given group of time-frequency resources are only applied to data elements, not to the DMRS resource elements. | 12-19-2013 |
20130336135 | Selection of Precoding Vectors in Lean-Carrier Systems - In a system using spatial precoding, in the event that reliable channel state information is unavailable, a transmitting node artificially creates a randomization of the precoders applied to the transmitted signal.

In an LTE system in particular, this randomization of precoders can be applied at the resource-block level or, at the level of the Precoding Resource block Group (PRG), for example. Thus, the precoders applied to the transmitted signal vary from one PRG to the next, in a random or pseudo-random fashion. | 12-19-2013 |

20130242769 | Induced Incoherency for Joint Transmission - Frequency-selective phase shifts are applied to signals transmitted from multiple transmission points involved in a coordinated (joint) transmission to a given UE. An eNodeB or other network node controlling the joint transmission artificially induces frequency selectivity between signals received by the UE in joint transmission from different transmission points, so as to ensure an even balance between constructive and destructive combination over frequency. By applying frequency-selective phase shifts (e.g., pseudo-random phase shifts) to the different transmission points that perform joint transmission, the signals from the different transmission points are forced to combine at the UE in a non-coherent manner. As a result, uncertainty in how the signals combine is drastically reduced, since it can be expected that the signals will always combine incoherently. The reduced uncertainty translates to reduced back-off offset in the link adaptation, and thus in an increased throughput. | 09-19-2013 |
