Abstract: A user equipment (UE) can include processing circuitry configured to, during a physical random access channel (PRACH) procedure, select a first synchronization signal (SS) block from a plurality of SS blocks within a received SS burst set, the SS block selected based on signal quality measurements of the plurality of SS blocks. A PRACH preamble is encoded for transmission to a base station using a PRACH resource subset corresponding to the selected SS block, the transmission using a UE transmit (Tx) beam of a plurality of available Tx beams and transmit power indicated by a power ramping counter. Upon failing to detect a random access response (RAR) from the base station, a second SS block is selected, the power ramping counter is reset, and the PRACH preamble is encoded for re-transmission using a second PRACH resource subset and transmit power indicated by the reset power ramping counter.

Abstract: An apparatus of a Narrowband Internet-of-Things (NB-IoT) user equipment (UE) includes processing circuitry. To configure the NB-IoT UE for open loop transmit power control, the processing circuitry is to decode a narrowband system information block (NB-SIB) to obtain a narrowband physical random access channel (NPRACH) resource set and power control information associated with the NPRACH resource set. A random access channel (RACH) preamble is encoded for transmission with or without repetitions to a base station during a RACH procedure and using the NPRACH resource set. The transmission has transmission power based on the power control information. A narrowband uplink resource assignment received during the RACH procedure is decoded. A connection setup completion message is encoded for transmission to the base station using the narrowband uplink resource assignment.

Abstract: DRS signaling are described herein in which the DRS transmissions may be used in a Long Term Evolution (LTE)-Licensed Assisted Access (LAA) Secondary Cell that is subject to Listen Before Talk (LBT). In some implementations, the DRS transmission may include continuous symbol transmission in order to ensure that other nearby nodes, such as WiFi nodes, do not begin to transmit on the channel.

Abstract: Embodiments of wireless communication devices and methods for device discovery is generally described herein. Some of these embodiments describe an apparatus having processing circuitry arranged to configure a single-tone discovery signal for transmission in a symbol in a transmission opportunity based on an assignment pattern. The assignment pattern may define frequency positions, for a set of transmission opportunities, at which the apparatus shall transmit discovery signals in the corresponding transmission opportunity. The apparatus may have physical layer circuitry arranged to transmit the single-tone discovery signal in the corresponding transmission opportunity. Other methods and apparatuses are also described.

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(5 n)=1.2s(n), where s(n) is a maximum run length sequence (msequence) 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 receiver processes a data signal and provides an acknowledgement within a turnaround time through use of code block alignment, reduced complexity or increased processing time. In a first embodiment, a radio access network (RAN) node enables encoded information to be segmented into multiple code blocks and maps a group of code blocks to be aligned with orthogonal frequency division multiplexing (OFDM) symbol boundaries such that efficient receiver processing can implement processing pipelining. In a second embodiment, the transmitter can provide more time or reduce the complexity of the packet, such as by repetition of bits of code blocks of the encoded information or by reserving resource elements (REs) such that the receiver has effectively more time (or less complexity) to process the last or last few code blocks of the packet.
