Abstract: Methods and architectures for establishing an uplink control channel in a fifth generation (5G) or new radio (NR) wireless network includes transmitting scheduling requests (SRs) at sub-slot level/symbol-level periodicities and determining whether SR transmit opportunities will collide with downlink (DL) signals being received and halting an SR transmission if the timing of DL symbols overlap at an OFDM symbol with the SR transmission.

Abstract: Systems and methods of early termination of uplink data transmissions for a UE are described. The UE transmits capacity information that indicates that the UE supports use of an ETS. The ETS indicates successful reception by the eNB of the uplink data prior to an end of a scheduled transmission period to transmit repeated instances of the data. The UE receives a schedule for repeated transmissions of the data that is based on a coverage level of the UE, and then transmits sets of one or more repetitions. After the transmission, the UE monitors a predetermined resource whether the ETS is present or whether the ETS indicates an ACK. If the ETS indicates successful reception, the UE terminates transmission of the remaining repetitions of the data and enters a sleep mode or transmits other uplink data.

Abstract: A user equipment (UE) can include processing circuitry configured to decode physical uplink control channel (PUCCH) configuration information received from a Next Generation Node-B (gNB). The configuration information includes a cell-specific base sequence hopping pattern. A PUCCH base sequence is selected from a plurality of available PUCCH base sequences based on the cell-specific base sequence hopping pattern and UCI information. A cyclic shift is applied to the PUCCH base sequence to generate a cyclically shifted PUCCH sequence. The cyclically shifted PUCCH sequence is encoded for transmission to the gNB using a PUCCH physical resource. The cyclically shifted PUCCH sequence carries the UCI and is code division multiplexed (CDM) with at least another cyclically shifted PUCCH sequence within the PUCCH physical resource.

Abstract: Technology for a user equipment (UE) operable to encode a New Radio (NR) short duration physical uplink control channel (PUCCH) for transmission to a Next Generation NodeB (gNB) is disclosed. The UE can identify uplink control information (UCI) for the UE. The UE can multiplex, using frequency division multiplexing (FDM) at the UE, the UCI and a pseudo-random sequence associated with a demodulation reference signal (DMRS) onto a plurality of subcarriers in one or more physical resource blocks (PRBs) of one or more orthogonal frequency division multiplexing (OFDM) symbols. The UE can encode the UCI and the pseudo-random sequence associated with the DMRS multiplexed onto the plurality of subcarriers of the one or more OFDM symbols for transmission on the NR short duration PUCCH to the gNB.

Abstract: Techniques discussed herein can facilitate RS (Reference Signal) sequence generation and mapping, and/or precoder assignment, for NR (New Radio). One example embodiment employable at a NR wireless communication device comprises processing circuitry configured to: generate one or more PN (Pseudo Noise) sequences based at least in part on an initial state of a PN generator; extract, for each PRB (Physical Resource Block) of one or more PRBs, an associated portion of an associated PN sequence of the one or more PN sequences, based at least in part on a reference subcarrier index, independent of a bandwidth part configuration and of a maximum supported number of PRBs; and generate, for each PRB of the one or more PRBs, an associated set of RS(s) for that PRB based at least in part on the extracted associated portion of the associated PN sequence for that PRB.
