Abstract: Wireless communications systems and methods related to improve control reporting latency are provided. A wireless communication device receives, from a first link in a first time interval, first control information associated with a second link and the first time interval. The wireless communication device transmits, via the second link in the first time interval, a control report associated with the second link based on a report configuration that is independent from the first control information. The report configuration is associated with a waveform type. The wireless communication device receives, from the first link in a second time interval following the first time interval, second control information that is dependent on the control report. The report configuration includes a power headroom (PHR) report configuration. The PHR report configuration includes a reference PHR report configuration. The PHR report configuration includes a delayed PHR report configuration.

Abstract: NB wireless communication involves numerous challenges. A limited frequency dimension may need to be shared by multiple users. At times, large data transmissions, including multiple TBs of data may be transmitted using NB communication, and it may be important that each TB be successfully received by the users. The apparatus may transmit data comprising a plurality of TBs in a narrow band communications system, including repeating a transmission of the plurality of TBs, using any of a number of repetition patterns. The apparatus may use error correction encoding across multiple TBs. The transmission may be a single cell transmission or a multi-cell transmission.

Abstract: A method and apparatus for enabling an UE to selecting acknowledgement/non-acknowledgement (ACK/NACK) resources from a subset of a gNB resource pool. The example method may receive, from an gNB, a radio resource control (RRC) configuration indicating a UE-specific resource set that is a subset of a gNB resource pool. The UE may determine one or more ACK/NACK resources from the UE-specific resource set for an upcoming physical uplink control channel (PUCCH). In some aspects, the UE may determine the one or more ACK/NACK resources based on receiving, from the gNB, a physical downlink control channel (PDCCH) including a corresponding ACK/NACK resource configuration. In other aspects, the RRC may contain multiple resource subsets and the UE may determine the one or more ACK/NACK resources based on determining a size of a payload for a UCI to be transmitted on the PUCCH. The aspects may thus enable dynamic ACK/NACK resource allocation.

Abstract: Methods, systems, and devices for wireless communication are described that provide for uplink channel multiplexing and waveform selection. Uplink channels to be transmitted from one or more user equipment (UEs) to a base station are multiplexed together or separately into an uplink subframe. Each UE is capable of using different waveforms to transmit different channels. Reference signals are communicated according to an RS pattern, which is symmetric across uplink and downlink channels.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network controller may determine a first set of spreading sequences and a second set of spreading sequences for non-orthogonal multiple access (NOMA) communication, wherein the first set of spreading sequences is different than the second set of spreading sequences; and configure a first cell to use the first set of spreading sequences and a second cell to use the second set of spreading sequences; or configure the first set of spreading sequences to be used for first user equipment associated with a cell center of the first cell and the second set of spreading sequences to be used for second user equipment associated with a cell edge of the first cell or the second cell. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that support pairwise cross correlation sequences for non-orthogonal multiple access wireless communications. A user equipment (UE) may receive, from a base station, an indication of a spreading factor and a number of transmitters in a group of non-orthogonal multiple access (NOMA) transmitters configured for concurrent transmissions. The UE may determine, based on the spreading factor and the number of transmitters, a first spreading sequence of a set of spreading sequences from a first codebook, the first spreading sequence having a defined value for pairwise cross correlation with each spreading sequence of the plurality of spreading sequences. The first UE may identify data to be transmitted in an uplink transmission, apply the first spreading sequence to the data to be transmitted in the uplink transmission, and transmit the uplink transmission to the base station.

Abstract: A wireless device may identify a set of resources reserved for feedback information (e.g., resource elements (REs) reserved for feedback such as acknowledgement (ACK) or negative ACK (NACK) information) within a transmission time interval (TTI). Feedback information may be mapped to the reserved set of resources (e.g., reserved REs). The wireless device may determine a set of unused reserved resources (e.g., a set of unused reserved REs) based on the number of feedback bits. The wireless device may then map other bits (e.g., zeros, known bits, pattern or sequence of bits, random bits, etc.) to the set of unused reserved REs, or boost transmission power of bits mapped around the unused reserved REs. In some cases, the number of reserved REs may be determined based on the number of feedback bits (e.g., the size of the ACK/NACK payload). The wireless device may then transmit the information to a base station.

Abstract: Methods, systems, and devices for wireless communications are described that provide a number of groups of transmitters, each group of transmitters having at least one user equipment (UE), and each group of transmitters having an associated transmission opportunity (TXO) for transmission of a reference signal. A number of UEs may transmit transmissions to a base station according to non-orthogonal multiple access (NOMA) techniques in which two or more UEs concurrently transmit to the base station. Depending upon a number of UEs, a number of groups of transmitters, an overloading factor of NOMA transmissions, a system bandwidth, a time span of the reference signal TXO, or any combination thereof, a binary or non-binary orthogonal cover code (OCC) may be applied to transmitted reference signals, which the base station may use to identify reference signals from particular UEs.

Abstract: A configurable new radio (NR) RACH procedure that may be executed by a UE and a base station is disclosed. A first message can be transmitted, in an inactive or idle state, a on a physical random access channel, where the first message includes a random access preamble. A second message can be received on a downlink channel in response to the first message, where the second message includes a temporary cell radio network temporary identifier and an uplink grant for the user equipment. A request can be transmitted on an uplink channel based on the uplink grant. A common search space of a downlink control channel can be monitored, such as for an acknowledgement message or a negative acknowledgement message corresponding to the request and identifiable based on the temporary cell radio network temporary identifier.

Abstract: Repeated signals for narrowband internet of things (NB-IoT) and machine type communication (MTC) may be transmitted using various non-orthogonal multiple access (NOMA) techniques. A user equipment (UE) may generate a set of modulated symbols associated with the data stream, spread the set of symbols using a spreading factor, and may subsequently apply a scrambling sequence to the set of symbols. The spread and scrambled symbols may be transmitted as a time domain waveform that includes one or more repetitions of a transmission time interval (TTI) or a resource unit (RU). Additionally, or alternatively, the UE may perform rate matching and apply the scrambling sequence to achieve the repetitions of the TTIs or RUs. In some cases, the UE may transmit a set of orthogonal pilot signals with the repetitions of the TTIs or RUs, where the pilot signals include different cyclically shifted versions of a base pilot signal.
