Abstract: Techniques discussed herein can facilitate RS (Reference Signal) sequence generation and mapping, and/or precoder assignment, for NR (New Radio). One example embodiment employable at a NR wireless communication device comprises processing circuitry configured to: generate one or more PN (Pseudo Noise) sequences based at least in part on an initial state of a PN generator; extract, for each PRB (Physical Resource Block) of one or more PRBs, an associated portion of an associated PN sequence of the one or more PN sequences, based at least in part on a reference subcarrier index, independent of a bandwidth part configuration and of a maximum supported number of PRBs; and generate, for each PRB of the one or more PRBs, an associated set of RS(s) for that PRB based at least in part on the extracted associated portion of the associated PN sequence for that PRB.

Abstract: In some embodiments, an apparatus of a Fifth Generation (5G) NodeB (gNB) comprises one or more baseband processors to encode one or more channel state information reference signals (CSI-RS) to be transmitted to a user equipment (UE). The one or more CSI-RS signals comprise a complex sequence mapped to a resource element (RE) such that all CSI-RS ports use an identical sequence for the one or more CSI-RS signals in a symbol. In other embodiments, the gNB comprises one or more baseband processors to encode a scrambling identity (ID) configuration for one or more demodulation reference signals (DMRS), wherein the scrambling ID configuration indicates one of two scrambling IDs to be signaled to a UE.

Abstract: Embodiments of the present disclosure describe apparatuses, systems, and methods for initialization of pseudo noise (PN) sequences for reference signals and data scrambling. Some embodiments may be to initialize the first M-sequence of the PN sequence with a fixed value; and initialize the second M-sequence of the PN sequence with a compressed value. Some embodiments may be to initialize the first M-sequence of the PN sequence with a fixed value; initialize the second M-sequence of the PN sequence with a part of the initialization parameters; and shift the PN sequence by another part of the initialization parameters. Some embodiments may be to initialize the first M-sequence of the PN sequence with a part of the initialization parameters; and initialize the second M-sequence of the PN sequence with another part of the initialization parameters. The embodiments may lead to a more efficient hardware design.

Abstract: Technology for a user equipment (UE) operable to enhance the receiving performance of a reference signal for beam refinement is disclosed. The UE can determine a receiving beam sweeping structure for each receiving beam of a plurality of receiving beams. The UE can calculate the receiving power rj for each of the plurality of receiving beams. The UE can select a refined receiving beam having a highest receiving power rj.

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.
