Techniques discussed herein can facilitate power ramping of PRACH (Physical Random Access Channel), for example, in connection with change of best gNB (next generation Node B) Tx (Transmit) beam and/or dynamic beam switching for control and/or data channels. Power ramping techniques discussed herein can comprise techniques for determining at least one of a power ramping counter or power offset for PRACH in connection with a change in best DL (Downlink) Tx (Transmit) beam. Dynamic beam switching techniques discussed herein can comprise employing DCI comprising at least one beam indication field indicating a beam index of a new beam of a BPL (Beam Pair Link) for at least one of a data channel or a control SS (Search Space).

Methods, systems, and storage media are described for random access procedures triggered based on physical downlink control channel (PDDCH) orders. Other embodiments may be described and/or claimed.

Random access procedures based on physical downlink control channel (PDDCH) orders

Various embodiments are generally directed to improved channel quality information feedback techniques. In one embodiment, for example, an apparatus for a base station is provided that includes a radio interface and a processor coupled to the radio interface. The processor is configured to receive a channel quality indicator (CQI) index, wherein the CQI index is based on a channel state information (CSI) reference resource, further wherein a first three orthogonal frequency-division multiplexing (OFDM) symbols of the CSI reference resource are occupied by control signals, select a modulation and coding scheme (MCS) for a physical downlink shared channel (PDSCH) based on the CQI index, and cause transmission of the PDSCH based on the selected MCS via the radio interface. Other embodiments are described and claimed.

Channel quality information feedback techniques

Systems and methods for synchronizing communications between a User Equipment (UE) and Base Station (BS) using a synchronization signal structure. The synchronization signal structure can include a sequence of Synchronization Signals (SS) including repetitions of a synchronization signal burst set. The synchronization signal burst set can include a plurality of synchronization signal bursts. The synchronization signal bursts can include a plurality of synchronization signal blocks, wherein the synchronization signal blocks can include a plurality of Synchronization Signals (SS).

Synchronization signal transmission techniques

Systems, devices, and techniques for indicating the number of repetitions for a downlink control information (DCI) message are described. A described technique includes transmitting an indication of a repetition number for a downlink control information (DCI) message having a predetermined format for transmit power control (TPC) of an uplink channel by a user equipment (UE); and transmitting, to the UE via a machine-type communications physical downlink control channel (MPDCCH), repetitions of the DCI message in accordance with the predetermined format and in accordance with the repetition number. The predetermined format can based on a DCI format 3 or 3A for bandwidth-reduced low-complexity or coverage enhanced (BL/CE) UEs.

Indication of the number of repetitions for dci format 3/3A for EMTC

A service device (e.g., a user equipment (UE), a new radio NB (gNB), or other network component or network management component) can process or generate a Downlink Control Information (DCI) that schedules a Physical Uplink Shared Channel (PUSCH) transmission in a PUSCH. The PUSCH transmission can be generated based on a Demodulation Reference Signal (DMRS) according to a Discrete Fourier Transform (DFT) spread Orthogonal Frequency Division Multiplexing (DFT-s-OFDM) waveform in uplink. A sequence of the DMRS can be generated based on a Gold sequence and a Pi/2 Binary Phase-Shift Keying (BPSK) modulation.

Technology for a user equipment (UE) operable to perform downlink (DL) channel quality measurement reporting is disclosed. The UE can decode a system information block type y bandwidth reduced (SIBy-BR) received from an eNodeB. The SIB1-BR can instruct the UE to include a DL channel quality measurement report in a message 3 (Msg3) transmitted during a random access procedure between the UE and the eNodeB, wherein y is a positive integer greater than or equal to 1. The UE can determine a DL channel quality measurement for a DL channel between the UE and the eNodeB. The UE can encode the Msg3 for delivery over an uplink channel to the eNodeB. The Msg3 can be delivered during the random access procedure and can include the DL channel quality measurement report with the DL channel quality measurement.

Channel quality measurement reporting

Described is an apparatus of a User Equipment (UE) operable to communicate with a fifth-generation Evolved Node-B (gNB) on a wireless network. The apparatus may comprise a first circuitry and a second circuitry. The first circuitry may be operable to process a message comprising an indicator to indicate a number of contention based physical random access channel (PRACH) preambles within a PRACH occasion per Synchronization Signal Block (SSB). The second circuitry may be operable to generate a first PRACH occasion, based on the indicator.

Control resource set information in physical broadcast channel

Communication in a wireless network using a phase-tracking reference signal (PT-RS) for orthogonal frequency division multiplexing (OFDM) includes determining one or more PT-RS groups of adjacent subcarriers in a resource allocation for a physical uplink shared channel (PUSCH) or a physical downlink shared channel (PDSCH), encoding data to be transmitted by the PUSCH or the PDSCH in data subcarriers within the resource allocation for the PUSCH or the PDSCH, and encoding phase-tracking reference signals within the one or more PT-RS groups of adjacent subcarriers.

Systems and methods of phase-tracking reference signal transmission for OFDM

The processor circuitry is configured to perform a downlink (DL) quality measurement, and to generate a DL quality report based on the DL quality measurement, wherein a definition of the DL quality report matches a definition of quality report in Msg3. The radio front end circuitry is configured to transmit the DL quality report to a next generation base station (gNB).
