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: Various aspects of the present disclosure provides methods and techniques for flexible positioning of a uplink short burst in NR communications. In one example, the uplink short burst may have a slot position that at any position of the uplink centric slot. For instance, a downlink centric slot may contain control signals from a base station, such as a grant, that indicate the slot position of the uplink short burst. The grant may indicate, explicitly or implicitly, the position within an uplink centric slot that should be assigned to an uplink short burst. The UE may then transmit a response including an uplink short burst within the indicated slot position of an uplink centric slot. The various aspects may thus enable the dynamic assignment of uplink short bursts within uplink centric slots.

Abstract: Signaling strategies for an advanced receiver with interference cancellation (IC) and suppression is discussed. Upon enablement of an advanced interference cancellation procedure according to the disclosure, transmitters within the enabled area transmit according to transmission restriction configurations that provide transmission limits based on either frequency, time, or scheduling. The restrictions on the transmitters reduces the complexity of processing by neighboring advanced receivers for cancellation of interference from the restricted transmitters. At the advanced receiver, transmission information, such as scheduling, reference signal (RS), resource block (RB) allocation, and the like, may either be determined through blind detection or received directly through signaling. The advanced receiver may use this transmission information associated with each interfering signal to detect, decode, and subtract the interfering signals from the received transmissions.

Abstract: Techniques for performing peer discovery to enable peer-to-peer (P2P) communication are disclosed. In an aspect, a proximity detection signal used for peer discovery may be generated based on one or more physical channels and/or signals used in a wireless network. In one design, a user equipment (UE) may generate a proximity detection signal occupying at least one resource block based on a SC-FDMA modulation technique. In another design, the UE may generate a proximity detection signal occupying at least one resource block based on an OFDMA modulation technique. The UE may generate SC-FDMA symbols or OFDMA symbols in different manners for different physical channels. In yet another design, the UE may generate a proximity detection signal including a primary synchronization signal and a secondary synchronization signal. For all designs, the UE may transmit the proximity detection signal to indicate its presence and to enable other UEs to detect the UE.

Initial power level selection may account for, or be based on, one or more channel conditions associated with the physical random access channel. Initial power level selection may be based on signaling of available initial power transmission levels and a reference signal received power measurement.

Abstract: Methods, systems, and devices for line of sight (LOS) multiple input multiple output (MIMO) signaling aspects are described. In some examples, a wireless device may transmit, to a network device, a capability message indicating that the wireless device supports a LOS mode. In such examples, the wireless device may receive, from the network device in response to the capability message, a control message indicating activation of the LOS mode and at least one LOS mode parameter based at least in part on a channel measurement associated with a wireless channel between the wireless device and the network device indicating that the wireless channel satisfies a LOS path criterion. In some examples, the wireless device may communicate a message with the network device in accordance with the LOS mode parameter.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, a base station may dynamically and reliably indicate that pending transmissions are part of a full duplex operation via downlink control information (DCI) designs described herein. For example, a base station may transmit, to a user equipment (UE) a DCI including no more than one downlink grant and no more than one uplink grant for a full duplex operation. In some examples, the base station may transmit a first-stage DCI including partial information, and second-stage DCIs including full uplink and downlink grants for a full duplex operation. In some examples, the base station may configure periodic or semi-periodic uplink and downlink resources that may overlap in time, and may dynamically indicate, to the UE, whether the overlapping uplink and downlink resources are scheduled for a full duplex operation.
