Abstract: Systems and methods use multiple spatial layers for physical multicast channel transmission. Certain embodiments introduce additional multimedia broadcast multicast service reference signals that support more than one antenna ports for multicast broadcast single frequency network transmissions. To reduce channel estimation complexity due to the multicast broadcast single frequency network reference signal design, resource elements of the multicast broadcast single frequency network reference signals may have a nested structure. To assist modulation and coding scheme selection, a user according to certain embodiments also independently reports block error rate measurements for each spatial layer of the multicast channel.

Abstract: Described is a UE to communicate with an eNB on a network, the UE comprising: an antenna to receive messaging from eNB indicating switching to 256-QAM scheme from an existing non-256-QAM scheme; and a table component for storing soft channel bits based on Nsoft such that the number and value of the soft channel bits for using the 256-QAM scheme is substantially equal to the number and value of the soft channel bits when the UE is not using the 256-QAM scheme. Described is an eNB comprising: an antenna to transmit messaging to a UE indicating switching to 256-QAM scheme from an existing non-256-QAM scheme; and an encoder to encode data using memory usage size based on Nsoft such that the number and value of the Nsoft for using the 256-QAM scheme is substantially equal to the number and value of the Nsoft when the eNB is not using the 256-QAM scheme.

Abstract: Examples include techniques for using a modulation and coding scheme (MCS) for downlink transmissions. In some examples information elements (IEs) for either a physical multicast channel (PMCH) or a physical multicast control channel (PMCCH) include information to indicate an MCS for downlink transmission over a PMCH or PMCCH between an evolved Node B (eNB) and user equipment (UE). For these examples, the information in the IEs include indications of whether higher order modulation for quadrature amplitude modulation (QAM) have or have not been enabled. Both the UE and the eNB may operate in compliance with one or more 3rd Generation Partnership Project (3GPP) Long Term Evolution (LTE) standards.

Abstract: Technology for reducing signal interference is disclosed. Semi-static signaling can be received at a user equipment (UE) from a neighboring evolved node (eNB). The semi-static signaling can include potential configurations of signal parameters used at the neighboring eNB. The UE can receive dynamic signaling from the neighboring eNB that includes a subset of the potential configurations of signal parameters used at the neighboring eNB. Signal interference that is caused by the neighboring eNB can be reduced using the semi-static signaling and the dynamic signaling.
