Abstract: Described is an apparatus of an eNB operable to communicate with a UE on a wireless network. The apparatus may comprise a first circuitry, a second circuitry, a third circuitry, and a fourth circuitry. The first circuitry may be operable to process a first transmission carrying a DM-RS antenna port group indicator and a second transmission carrying an antenna port configuration indicator. The second circuitry may be operable to select a DM-RS antenna port group comprising a set of antenna port configurations based upon the DM-RS antenna port group indicator. The third circuitry may be operable to select an antenna port configuration out of the set of antenna port configurations based upon the antenna port configuration indicator, the antenna port configuration comprising one or more DM-RS antenna ports. The fourth circuitry may be operable to process a third transmission carrying DM-RS in accordance with the selected configuration.

Abstract: A scrambling sequence generation method is disclosed for reference signals, data, and downlink and uplink control channels. The scrambling sequence generation method determines an initial seed value used to calculate the scrambling sequence. The initial seed value is based on different parameters relating to the to be transmitted signals, and some of these parameters are explicitly defined for New Radio.

Abstract: Techniques for detecting puncturing of a first PDSCH (physical downlink shared channel) associated with a UE (user equipment) by a second PDSCH with a shorter TTI (transmission time interval) are discussed. A base station (e.g., Evolved NodeB or eNB) can configure the UE for potential puncturing and/or parameter(s) of the second PDSCH. The UE can detect puncturing of the first PDSCH based on the configuration, and can discard punctured symbols to mitigate interference from the second PDSCH.
