Abstract: Aspects of the disclosure relate to wireless communication systems configured to provide techniques for utilizing a one-symbol space-time block code (STBC) process to encode control information for transmission on an uplink control channel. The one-symbol STBC process produces two code blocks, each for transmission on a different antenna. Each code block may be time domain spread across multiple single-carrier frequency division multiple access (SC-FDMA) uplink control channel symbols using the same spreading code to enable recovery of the code blocks at the receiver.

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: Methods, systems, and devices for power control in New Radio (NR) systems are described. In one example, a user equipment (UE) may determine a transmit power for a control channel based on an effective code rate of control information to be transmitted in the control channel. In another example, the UE may be configured to use a different transmit power for repeated transmissions of control information in a control channel. In yet another example, the UE may be configured to determine a transmit power for a transmission in a time interval or scale a transmission in a time interval based on a priority of the transmission relative to other transmissions scheduled in the time interval. In yet another example, the UE may be configured to determine respective transmit powers for uplink transmissions multiplexed differently using different open-loop parameters.

Abstract: Methods, systems, and devices for wireless communication are described for grant-free admission control to a shared channel. A base station may select an admission control parameter from a set of admission control parameters, the selected admission control parameter setting a grant-free access threshold for determining eligibility to obtain grant-free access to resources of a shared channel. The base station may transmit the selected admission control parameter to configure a user equipment (UE) with the grant-free access threshold. A UE may receive an admission control parameter from the base station, and set a grant-free access threshold based at least in part on the admission control parameter. The UE may determine eligibility to obtain grant-free access to resources of a shared channel based at least in part on the grant-free access threshold, and communicate with the base station based at least in part on the determined eligibility.

Abstract: Aspects of the present disclosure provide for opportunistic uplink transmissions within a slot. In some examples, after scheduling all regular uplink transmissions within a current slot, a base station (e.g., gNB) may identify a set of unused uplink resources within the current slot and generate and transmit unused resource information identifying the set of unused resources to the user equipment (UE) within the cell served by the base station. If a particular UE is configured to operate in an opportunistic mode, the UE may utilize the unused resource information to generate and transmit an opportunistic uplink transmission within the set of unused uplink resources.

Abstract: Aspects of the present disclosure relate to wireless communication systems configured to provide user equipment (UE)-specific slot structures based on the individual propagation delay experienced by each UE. In some examples, the duration of uplink transmissions for a particular UE within a slot may be configured based on the propagation delay between the base station and that particular UE. For example, the duration of an uplink burst and/or an uplink traffic transmission may be configured based on the propagation delay. In addition, a downlink burst within a slot may be configured for a particular UE on the propagation delay experienced by that UE. Downlink traffic transmissions may further be configured for the cell based on the maximum propagation delay experienced by the UEs in the cell.

Abstract: Various reference signal (RS) designs and arrangements for interference coordination and management in wireless communication are disclosed. Reference signals may be included in uplink (UL) and downlink (DL) transmissions for facilitating data demodulation and other purposes, and the locations of the reference signals within any given slot may depend on various factors. In some aspects of this disclosure, reference signals included in UL and/or DL transmissions of neighboring cells may be aligned in time and/or frequency to improve interference control and coordination between devices operating in different cells.

Abstract: Methods, systems, and devices for wireless communication are described that support multiplexing uplink transmissions with transmit diversity with a single carrier waveform. Two or more UEs may be configured to use space time block codes (STBC) for transmissions using multiple uplink antennas. A first UE may be configured to use a first STBC for a first uplink transmission. An orthogonal cover code (OCC), such as a Walsh code, may be applied to the first STBC to generate a second STBC, and a second UE may use the second STBC for a second uplink transmission. The first UE and the second UE may concurrently transmit the first uplink transmission and the second uplink transmission. The first STBC and the second STBC may be applied across multiple OFDM symbols, or may be applied within an OFDM symbol on a modulated symbol level.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may perform one or more process that enable smart processing of resource elements from interfering base stations in order to improve cell decoding. The method includes prioritizing resource elements in order to reduce complexity of processing of the interfering resource elements. Some resource elements may be excluded from processing if priority is set to a null value or to a sufficiently low value. Resource elements in a subframe received from an interfering transmitter are grouped into one or more target regions and paired with serving and interfering cells. Each pairing is prioritized and processed in an order based on the priorities assigned to the pairings.
