Abstract: Various aspects of the disclosure relate to event triggers for independent links. For example, an event trigger may be based on measurements from multiple links. In some aspects, the independent links may involve a first device (e.g., a user equipment) communicating via different independent links with different devices (e.g., transmit receive points (TRPs) or sets of TRPs). For example, the first device may communicate with a second device (e.g., a TRP) via a first link and communicate with a third device (e.g., a TRP) via a second link. In some scenarios, an event trigger may be based on aggregated measurements from multiple links.

Abstract: A discovery measurement timing configuration (DMTC) window reservation signal is disclosed for new radio (NR) shared spectrum (NR-SS) networks. The DMTC window is defined providing a reserved location for transmission of essential control signaling and potentially high priority traffic that may be transmitted in a prioritized manner. Access within the DMTC window may be provided with a clear channel assessment (CCA) exempt transmission (CET) option or a non-CET option. When the CET option is used, the reservation duration and period may be conveyed through the channel reservation signal. User equipments (UEs) that detect the reservation signal may re-transmit with added offset to inform neighboring base station that may not be within range of the serving base station. Base station that receive either the transmitted or re-transmitted reservation signal will refrain from communications that may interfere with the reception at the UEs.

Abstract: Disclosed are techniques for determining a position of a user equipment (UE). A differential round-trip-time (RTT) based positioning procedure is proposed to determine the UE position. In this technique, the UE position is determined based on the differences of the RTTs between the UE and a plurality of base stations. The differential RTT based positioning procedure has much looser inter-gNodeB timing synchronization requirements than the OTDOA technique and also has much looser group delay requirements than traditional RTT procedures.

Abstract: Methods, systems, and devices for wireless communications are described. A configuration for a reference signal used to determine a non-linear behavior of transmission components at a transmitting device may be determined. The configuration for the reference signal may be determined based on signaling transmitted by the transmitting device, signaling transmitted by a device that receives the reference signal, or both. Additionally, or alternatively, the configuration for the reference signal may be determined based on a configuration of other signals transmitted by the transmitting device prior to or concurrently with the transmission of the reference signal. The determined configuration may be used to generate and transmit the reference signal or to determine a configuration of a received reference signal. In both cases, a non-linear response of transmission components at the transmitting device may be determined based on the reference signal.

Abstract: Aspects of the present disclosure describe receiving downlink signaling from an access point, determining, based at least in part on the downlink signaling, one or more precoders for uplink signaling, transmitting, to the access point and based at least in part on the one or more precoders, uplink signaling, and receiving, from the access point and based on transmitting the uplink signaling, a precoder indication to use the one or more precoders or one or more other precoders in transmitting uplink communications to the access point.

Abstract: Methods, systems, and apparatuses for uplink descriptor channels are described. An uplink descriptor channel may be used by a user equipment (UE) for providing indications that uplink transmissions over allocated uplink data resources are sent in a configuration different from a configuration indicated by an uplink grant. In various examples an uplink transmission may be transmitted by a UE, and received by a base station, and the uplink transmission may include the uplink descriptor channel with uplink data. An uplink descriptor channel may include indications that uplink control information is included in the uplink transmission, and/or that the uplink transmission employs a number of transmission intervals, a number of channels, and/or a different MCS than those indicated by the uplink grant. A base station may receive the uplink descriptor channel and adjust various parameters of decoding an uplink transmission and/or allocating radio frequency spectrum resources.

Abstract: Wireless communication techniques that include techniques for allocating resources for peak reduction tones are discussed. A UE may receive from a base station an indication of one or more frequency resources that are allocated for uplink communication. The UE may also receive from the base station an indication of a subset of the one or more frequency resources allocated for uplink communication that are also allocated for transmission of one or more peak reduction tones. The UE may transmit to the base station at least one peak reduction tone on at least one frequency resource of the subset of the one or more frequency resources. Other aspects and features are also claimed and described.

Abstract: Techniques for synchronization across transmitting nodes of a same public land mobile network (PLMN) operator using a shared radio frequency spectrum band may include initiating, at a first wireless node, a listen-before-talk (LBT) procedure for access to the shared radio frequency spectrum band, and identifying that a second wireless node associated with a same PLMN operator as the first wireless node has won contention for the shared radio frequency spectrum band. The first wireless node may discontinue the LBT procedure and initiate an auxiliary transmission using the shared radio frequency spectrum band concurrently with a primary transmission of the second wireless node.
