Abstract: Embodiments of the present disclosure describe apparatuses, methods and machine-readable storage medium for Reference Signal Received Power (RSRP) measurement and allocation of Downlink (DL) transmission resources. A user equipment (UE) may detect a first Synchronization Signal/Physical Broadcast Channel (SS/PBCH) block, and determine a subcarrier spacing (SCS) thereof. Mapping the first SS/PBCH block to OFDM symbols may be dependent on the SCS and a first SS/PBCH block index of the first SS/PBCH block. The UE may determine, based on the first SS/PBCH block and the SCS, a number of symbols of the slot or the slot pair for a CORESET for reception of a DL control channel associated with Remaining Minimum System Information (RMSI). The UE may decode the DL control channel in the CORESET. The DL control channel may be configured to indicate a DL data channel carrying the RMSI associated with the first SS/PBCH block.

Abstract: A device may obtain, from a user equipment (UE), first information relating to one or more signal strengths measured by the UE. A signal strength of the one or more signal strengths may be associated with a beam of a radio node. The device may identify, based on the first information, a particular signal strength that is associated with a particular beam. The device may select, based on the particular beam, one or more related beams that are associated with the particular beam. The one or more related beams may be associated with the particular beam based on historical data relating to historical signal strengths measured by a plurality of UEs. The device may provide, to the UE, second information that identifies the one or more related beams selected, to permit the UE to communicate using the one or more related beams.

Abstract: A method of generating channel estimates of a communication channel in an OFDM system includes receiving references symbols from at least one time frequency observation block of a predetermined block size in frequency and time; generating subspace-transformed reference symbols from the received reference symbols; and subspace filtering the subspace-transformed reference symbols to generate a channel estimate for a communication channel target time; wherein a latency between a communication channel time instant of a currently received reference symbol and the communication channel target time is smaller than the observation block size in time.

Abstract: Devices and methods of simultaneous data reception and measurement are generally described. A UE transmits to an eNB antenna capacity and receives a Beamformed Reference Signal (BRS) configuration in response. Beamformed signals from the eNB include a BRS subframe in accordance with the BRS configuration. The BRS subframe has a BRS whose structure depends on the UE antenna capacity. If the UE has a single antenna panels, neither an EPDCCH nor a PDSCH for the UE is in the BRS frame. If the UE has a single antenna panels and multiple ports or multiple antenna panels, the BRS may contain an EPDCCH or PDSCH for the UE as different ports or antenna panels may be assigned different functionality. The UE measures BRS Received Power (BRS-RP) of the BRS, transmits a BRS report based on the BRS-RP and selects an optimal beam based on BRS-RPs from BRSs of the beams.

Abstract: Systems and methods are disclosed for modulating wireless signals in 5G (and future 6G) networks, to mitigate faults from noise or interference, optimize reliability, and enhance message throughput, according to some embodiments. Versions may include modulation tables for phase and amplitude modulation of message symbols in which the number of amplitude levels is different from the number of phase levels. Alternatively, the number of amplitude levels and/or phase levels may be other than a power of two. Other versions may provide a non-uniform spacing of amplitude levels or phase levels for optimal SNR throughout. Specific modulation states of the modulation table may be excluded, or declared invalid for signaling, thereby increasing the noise immunity of the remaining valid states. Embodiments of the disclosed modulation tables can provide improved signal clarity, fewer dropped messages, fewer retransmit requests, higher throughput, faster uploads and downloads, and more satisfied wireless customers overall.

Another communication method includes transforming an information signal to a discrete lattice domain signal, shaping bandwidth and duration of the discrete lattice domain signal by a two-dimensional filtering procedure to generate a filtered information signal, generating, using a Zak transform, a time domain signal from the filtered information signal, and transmitting the time domain signal over a wireless communication channel.

Abstract: The described technology is generally directed towards dynamically changing which quadrature amplitude modulation (QAM) table a user equipment is to use based on channel quality information. A network schedules a user equipment with 256 QAM modulation if the user equipment recommends 256 QAM in the CQI report (and the scheduler decides to use 256 QAM for that particular user equipment). The network indicates to the user equipment that it has to use 256 QAM modulation and coding scheme (MCS) table and not the configured QAM MCS table while determining the scheduling parameters by decoding PDCCH.
