Abstract: Transmit diversity schemes may be used for sending sequence-based signals over multiple antennas. For example, a user equipment (UE) may determine an uplink sequence to be transmitted to a base station using multiple antennas. The UE may utilize a transmit diversity scheme for the multiple-antenna transmission of the uplink sequence, where the transmit diversity scheme utilized may be based on a number of symbol periods during which the sequence is transmitted. In accordance with the transmit diversity scheme, the UE may use multiple transmit antennas to transmit different sequences from respective antennas. In other examples, the UE may transmit the uplink sequence using different time or frequency resources. Additionally, the UE may use some combination of different transmit diversity schemes for sequence-based signals. In some aspects, the base station may provide an indication of the transmit diversity scheme that the UE is to use for transmitting the uplink sequence.

Abstract: Techniques described herein assist with indicating whether ACK/NACK signaling is present in an uplink transmission, thereby enhancing performance by permitting use of rate matching while reducing decoding errors. For example, a user equipment may determine whether ACK/NACK signaling is to be included in an uplink transmission in a portion of uplink resources allocated for a data channel, may generate a reference signal that indicates whether the ACK/NACK signaling is present in the uplink transmission, and may transmit the reference signal.

Abstract: Adjacent channel leakage-power ratio (ACLR) can be reduced at a transmitter of a device. A modulated signal can be mapped into a plurality of tone sets in a frequency domain, wherein the plurality of tone sets include a first, a second, and a third set of tones. The first and the third set of tones can be converted in the frequency domain to a fourth and a fifth set of tones, respectively, in a time domain. A zero padding of one or more symbols associated with the fourth and the fifth set of tones can be performed to output a sixth and a seventh set of tones, respectively. The sixth and the seventh set of tones can be converted to an eighth and a ninth set of tones, respectively, in the frequency domain. The eighth and the ninth set of tones can be processed for transmitting to another wireless device.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for physical uplink control channel (PUCCH) resource allocation. In certain aspects, a method for use by a user equipment (UE) for transmitting one or more uplink control information (UCI) bits in PUCCH includes determining resources allocated for providing one or more UCI bits based at least on a type of service associated with the UE and sending, to a base station, a PUCCH with the one or more UCI bits using the allocated resources.

Abstract: The present disclosure provides for adaptive resource management in new radio operations that favors the usage of resources for pilot signals and channel estimation in the transition slots of a slot burst, and the transmission of data in the subsequent slots of the slot burst. A device such as a user equipment (UE) and/or a base station may determine that the UE is operating in a transition state. The device may adapt a first numerology including a first number of symbols per slot used for transmission in the transition slots during the transition state, to a second scaled numerology including a second number of symbols per slot used for transmission in the subsequent slots after the transition state. A ratio of reference signal symbols to data symbol symbols may be greater in the transition slots than in the subsequent slots.

Abstract: Methods, systems, and devices for wireless communications are described in which different spreading sequences may be used to distinguish concurrent non-orthogonal multiple access (NOMA) transmissions. The spreading sequences may be selected based on one or more codebooks configured at a user equipment (UE) and a codebook for an uplink NOMA transmission determined based on a set of common resources allocated for the uplink NOMA transmission and a number of expected transmitters in a transmitter group. The UE may identify data to transmit in the uplink NOMA transmission, apply the spreading sequence to the data, and transmit the spread data in the uplink NOMA transmission. A base station may receive multiple concurrent uplink NOMA transmissions, perform receive signal processing to identify spreading signals and UE identity, de-spread the signals based on different spreading sequences, and demodulate and decode the de-spread signals of the NOMA UE.

Abstract: Methods, systems, and devices for wireless communication are described for defining uplink control channel resources and mapping uplink control channel resources to a user equipment (UE). Approaches described herein include identifying a physical uplink control channel (PUCCH) format to be used for a subsequent PUCCH transmission by the UE, identifying a PUCCH resource mapping rule based at least in part on the PUCCH format, and determining an uplink transmission resource to be used for the subsequent PUCCH transmission based at least in part on the PUCCH resource mapping rule. The PUCCH resource mapping rule may be explicit and/or implicit.

Abstract: Aspects of the present disclosure describe a guard band signal for communication on a guard band between a first frequency band utilized by a first radio access technology having a first sub-carrier spacing and a second frequency band utilized by a second radio access technology having a second sub-carrier spacing that is a multiple of the first sub-carrier spacing. The guard band signal includes a symbol that is repeated a number of times equal to the multiple. The guard band signal may be generated and transmitted by a transmitting device. The guard band signal may be received and decoded by a receiving device. The guard band signal is interpretable according to a first numerology of the first radio access technology and according to a second numerology of the second radio access technology.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for a power headroom report for multiple radio access technologies (RATs). A user equipment (UE) may support multiple RATs that correspond to different transmission time intervals (TTIs). A UE may determine a reporting schedule for power headroom reports (PHRs) for a first RAT and a second schedule for PHRs for a second RAT. The UE may generate a PHR for the first RAT and a companion PHR for the second RAT, and may transmit the PHR and companion PHR based at least in part on the first PHR schedule. In some examples, the UE may receive a PHR type from the base station, and may determine a joint PHR based on the type. The UE may determine a joint PHR schedule based on a granularity of supported RATs.
