Abstract: Techniques discussed herein can facilitate communication of group-based WUS(s) (Wake Up Signal(s)) for eMTC (enhanced Machine Type Communication) and/or NB (NarrowBand)-IoT (Internet of Things). One example embodiment is an apparatus configured to be employed in a UE (User Equipment), comprising: a memory interface; and processing circuitry configured to: determine a WUS group of a plurality of WUS groups, wherein the WUS group is associated with a first group WUS (Wake Up Signal) of a plurality of group WUSs; determine a starting subframe for the first group WUS; and monitor the starting subframe for the first group WUS, wherein the UE is configured to communicate via one or more of eMTC or NB (NarrowBand)-IoT.

Abstract: Provided herein are method and apparatus for perform radio link monitoring (RLM) based on a Reference signal (RS). An embodiment provides a user Equipment (UE) comprising circuitry configured to: decode a Reference Signal (RS) received from an access node; and determine beam quality for one or more beam pair links (BPLs) of the RS between the UE and the access node based on the decoded RS, wherein each of the BPLs comprises a transmit (Tx) beam of the access node and a receive (Rx) beam of the UE. Also provided is a procedure of RLM. At least some embodiments allow for beam recovery request for UE beam refinement, and allow for determining whether radio link failure (RLF) occurs.

Abstract: This disclosure proposes to use multiple power control loops in the uplink. Each power control loop may be associated with a respective antenna beam transmitted from an antenna array of the electronic device (e.g. UE) in the uplink. For example, a beam (or uplink signal) may be associated with 1, 2 or even more MIMO layer. Hence, in this latter case, each power control loop may be associated with a respective set of one or more MIMO layers. This concept is application to open-loop, closed-loop power control or both.

Abstract: Methods, systems, and storage media for providing multi-cell, multi-point single user (SU) multiple input and multiple output (MIMO) operations are described. In embodiments, an apparatus may receive and process a first set of one or more independent data streams received in a downlink channel from a first transmission point. The apparatus may receive and process a second set of one or more independent data streams received in a downlink channel from a second transmission point. The apparatus may process control information received from the first transmission point or the second transmission point. The control information may include an indication of a quasi co-location assumption to be used for estimating channel characteristics for reception of the first set of one or more independent data streams or the second set of one or more independent data streams. Other embodiments may be described and/or claimed.

Abstract: Technology for a Next Generation NodeB (gNB) operable to encode a primary synchronization signal for transmission to a user equipment (UE) is disclosed. The gNB can identify a sequence d(n) for a primary synchronization signal. The sequence d(n) can be defined by: d(n)=1−2s(n), where s(n) is a maximum run length sequence (m-sequence) and s(n) is provided as s(n+7)=(s(n+4)+s(n))mod 2, where 0≤n≤127. The gNB can generate the primary synchronization signal based on the sequence d(n). The gNB can encode the primary synchronization signal for transmission to the UE.

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: An approach is described that includes receiving a CSI report, where the CSI report includes a channel quality indicator (CQI), a rank indicator (RI), and a precoding matrix indicator (PMI). The approach further includes constructing a precoding matrix based on a linear combination of a plurality of mutually orthogonal digital Fourier transformation (DFT) spatial beams, and determining a number of bits for the PMI of the precoding matrix. The approach also includes determining a space frequency matrix based, at least in part, on the number of bits for the PMI and the precoding matrix, and compressing the space frequency matrix. Finally, the approach includes determining a compressed PMI based, at least in part, on the space frequency matrix.

Abstract: Methods, systems, apparatus, and computer programs, for providing uplink control information to an access node. In one aspect, the method can include actions of determining, by a UE, a time-domain orthogonal cover code (OCC) for a PUCCH message of a UE to multiplex the PUCCH transmission with one or more PUCCH messages from one or more other UEs, and encoding, by the UE, the PUCCH message for transmission by the UE using the OCC.
