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).
Abstract:
Embodiments of a User Equipment (UE), an Evolved Node-B (eNB), small-cell access point (AP), and methods for dynamic millimeter wave pencil cell communication are generally described herein. The UE may receive access point reference signals (APRS) from one or more small-cell access points (AP), and may transmit APRS signal quality measurements to a macro-cell Evolved Node-B (eNB). The UE may receive, from the macro-cell eNB, a message that indicates candidate pencil cells for which the UE is to determine signal quality measurements, the candidate pencil cells supported by the small-cell APs. The UE may receive beam reference signals (BRS) for the candidate pencil cells and may refrain from reception of BRS for pencil cells not included in the message. In some cases, beam-widths of the APRSs may be larger than beam-widths of the BRSs.
Abstract:
Embodiments herein may relate to transmission, in a first physical channel transmission, of an indication of a first set of parameters related to a control channel; and transmission, in a control channel transmission using the first set of parameters, of an indication of a second set of parameters related to the control channel. Further embodiments may relate to identifying a first parameter related to interleaving REGBs of a PDCCH transmission, wherein the first parameter is selected from a first plurality of parameters; interleaving the REGBs based on the first parameter to form a CCE, and transmitting die CCE in the PDCCH transmission. Other embodiments may be described and/or claimed.
Abstract:
Some demonstrative embodiments include devices, systems and methods of relay backhauling with millimeter wave carrier aggregation. For example, a first Relay Node (RN) may include a cellular transceiver configured to communicate with a Donor evolved Node B (DeNB) over a cellular frequency band of a Primary cell (PCell); a millimeter-wave (mmWave) transceiver to communicate with a second RN via a backhaul link over a mmWave frequency band of a Secondary cell (SCell) within the PCell; and a controller to process a Relay-Physical-Downlink-Control-Channel (R-PDCCH) message received by the cellular transceiver over the cellular frequency band of the PCell, the R-PD-CCH message including cross-carrier scheduling information to schedule a downlink allocation over the backhaul link, the controller to trigger the mmWave transceiver to receive a downlink data packet from the second RN during the downlink allocation.
Abstract:
Various techniques for collective perception messaging are disclosed herein. In an example, a machine receives, from a source device, a signal value for provision to a sink device, the signal value corresponding to a measurement of an environmental value. The machine accesses, from a storage device, an error term for the signal value. The machine accesses, from the storage device, a source reliability term for the source device. The machine accesses, from the storage device, a source-sink relation term based on the source device and the sink device. The machine determines a distribution for the environmental value based on the error term, the source reliability term, and the source-sink relation term. The machine determines, based on the distribution for the environmental value, whether the signal value is reliable.
Abstract:
The present disclosure relates to a method and related mobile device for estimating a channel by choosing a subset of correlated channel coefficients and estimating the reference signal received power of the subset of correlated channel coefficients based on a cross-correlation between channel coefficients of the subset of correlated channel coefficients.
Abstract:
Disclosed are UE-feedback techniques to support the adaptive DMRS transmission. A UE and eNB support adaptive DMRS transmission in which an eNB adjusts (i.e., selects) a DMRS pattern based on information describing channel conditions perceived by the UE. The UE may explicitly provide the channel conditions, or implicitly provide them by selecting a desired DMRS pattern.

Provided herein are method and apparatus for numerology configuration in non-coherent joint transmission. The disclosure provides an apparatus for a user equipment (UE), comprising circuitry configured to: determine one or more numerologies defined for at least one of different codewords, different layers, and different links for a non-coherent joint transmission (NCJT) to the UE, the NCJT comprising a first transmission from a first access node and a second transmission from a second access node; and process the NCJT according to the determined one or more numerologies. Also provided is a configuration of one or more transmission schemes for at least one of different codewords, different layers, and different links for a NCJT to the UE. Some embodiments allow for uplink NCJT with one or more numerologies defined for at least one of different codewords, different layers, and different links.

This disclosure relates to a beamforming controller for a beamforming transmitter device, the beamforming controller comprising a control element configured to: activate a first configuration state of a plurality of configuration states for a control channel, each configuration state indicating a beam direction of the control channel; control a beam switching of the control channel from the first configuration state to a second configuration state based on a beam direction of the control channel according to the first configuration state; and retransmit signaling of the beam switching based on a beam direction of the control channel according to both the first and the second configuration state if an acknowledgement to the beam switching is null, not received, missing or received in error.
Abstract:
A random access procedure is described for beam-based cell-less operations in fifth generation radio access technology. In one example a preamble transmission power, a preamble format, and a transmit timing are jointly determined at a user equipment (UE) for respective ones of one or more physical random access channel (PRACH) preamble transmissions. The determined preamble transmission powers, preamble formats, and transmit timing, multiple PRACH preamble transmissions are transmitted each to a target access point (AP). Based on the transmitted PRACH preamble transmissions, the UE the receives at least one random access response (RAR) message with an indication of timing advance (TA) values and beams of each target AP.
