    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: Techniques for channel state information (CSI) reporting are discussed. One example apparatus at a user equipment can derive, for one or more subframes of a license assisted access (LAA) secondary cell (SCell), one or more channel measurements based on reference signals (e.g., cell-specific reference signals (CRS) or CSI reference signals (CSI-RS)), in those subframes; generate CSI that comprises a channel quality indicator (CQI) based on an average of the one or more channel measurements from multiple subframes comprising a first subframe and a later second subframe, wherein each orthogonal frequency division multiplexing (OFDM) symbol of a second slot of the first subframe is occupied, wherein each of a first three OFDM symbols of the second subframe are occupied, and wherein each OFDM symbol between the first subframe and the second subframe is occupied; and generate a CSI report that indicates the set of CSI parameters.

    Abstract: A user equipment (UE) can include processing circuitry configured to decode control information of a physical downlink control channel (PDCCH) received via a resource within a control resource set (CORESET) occupying a subset of a plurality of OFDM symbols within a slot. At least one of the symbols in the subset coincides with a pre-defined symbol location associated with a demodulation reference signal (DM-RS) of a PDSCII. The DM-RS can be detected within the slot, the DM-RS starting at a symbol location that is shifted from the pre-defined symbol location and following the subset of symbols. Downlink data scheduled by the PDCCH and received via the PDSCH can be decoded, where the decoding is based on the detected DM-RS.

    Abstract: In one embodiment, an apparatus includes memory storing instructions and processing circuitry coupled to the memory. The processing circuitry is to implement the instructions to select a resource block group (RBG) size configuration from a set of RBG size configurations based on a bandwidth part (BWP) size. Each RBG size configuration is to indicate RBG sizes associated with respective ranges of BWP sizes, and the RBG sizes are to indicate a number of frequency-domain physical resource blocks (PRBs) for physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) transmissions. The processing circuitry is further to implement the instructions to allocate PRBs for communication between the gNB device and a user equipment (UE) device via the PDSCH or PUSCH transmissions based on the selected RBG size, and to encode downlink control information (DCI) that indicates the allocated PRBs for transmission to the UE device.

    Abstract: Described is an apparatus of a User Equipment (UE) operable to communicate with an Evolved Node-B (eNB) on a wireless network. The apparatus may comprise a first circuitry, a second circuitry, and a third circuitry. The first circuitry may be operable to process a configuration transmission carrying a half-tone shifting indicator. The second circuitry may be operable to select one or more subcarrier frequencies for Uplink (UL) transmission based on the half-tone shifting indicator. The third circuitry may be operable to generate a UL transmission for the one or more subcarrier frequencies. The half-tone shifting indicator may have a first value indicating application of a half-subcarrier offset, and a second value indicating no application of the half-subcarrier offset.

    Abstract: Devices, methods, user equipment (UE), evolved node B (eNB), and storage media are described suitable for coexistence operations for uplink communications on multiple unlicensed carriers. Various embodiments are implemented in LTE systems with license-assisted access (LAA) associated communications. In one embodiment, a UE processes one or more uplink grants from an eNB scheduling transmissions on multiple unlicensed carriers at a first time, and indicating a first channel access procedure. The UE then selects a first unlicensed carrier and performs the first channel access procedure, and performs a second channel access procedure on a second unlicensed carrier of the multiple unlicensed carriers.
