Abstract: A method of wireless communication includes receiving a first interference signal and a second interference signal. The method further includes determining whether the second interference signal includes a different version of the first interference signal. Additionally, the method includes combining the first interference signal and the second interference signal to estimate an interference cancellation signal when the second interference signal is the different version of the first interference signal.

Abstract: A backhaul quality is measured. One or more subsets of cell identifiers having a mapped backhaul quality that maps to the measured backhaul quality are identified. The one or more subsets have a set of cell identifiers associated therewith. A network is queried to indicate one or more cell identifiers in the identified subset of cell identifiers available for a user equipment (UE) relay. One of the one or more indicated cell identifiers is selected. If more than one subset of cell identifiers has a mapped backhaul quality that maps to the measured backhaul quality, first and second subsets having respective first and second mapped backhaul qualities are selected and the backhaul qualities are compared relative to a backhaul quality threshold. The mapped backhaul quality that most satisfies the backhaul quality threshold is identified for the network query.

Abstract: Position determination of a user equipment (UE) is supported using channel measurements obtained for Wireless Access Points (WAPs), wherein the channel measurements are for Line of Sight (LOS) and Non-LOS (NLOS) signals. Based on WAP almanac information and the channel measurements, channel parameters indicative of positions of signal sources relative to a first position of a UE may be determined. Using the first position of the UE and an association of the signal sources with corresponding channel parameters, a second position of the UE may be determined. The position of the UE may be a probability density function. Additionally, position information for signal sources may be determined, such as a probability density function, as well as signal blockage probability and an antenna geometry and the WAP almanac information may be updated accordingly.

Abstract: Various aspects of the disclosure relate to beam information for independent links. For example, beam information for one link may be sent on at least one other link. 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, one link can indicate beam switching for at least one other link. In some scenarios, one link can indicate link recovery for at least one other link. In some scenarios, one link can indicate link failure for at least one other link.

Abstract: Techniques for performing network-assisted peer discovery to enable peer-to-peer (P2P) communication are described. In one design, a device registers with a network entity (e.g., a directory agent) so that the presence of the device and possibly other information about the device can be made known to the network entity. The network entity collects similar information from other devices. The device sends a request to the network entity, e.g., during or after registration. The request includes information used to match the device with other devices, e.g., information about service(s) provided by the device and/or service(s) requested by the device. The directory agent matches requests received from all devices, determines a match between the device and at least one other device, and sends a notification to perform peer discovery. The device performs peer discovery in response to receiving the notification from the network entity.

Abstract: Methods, systems, and devices are described for wireless communication employing two-stage control channel messaging. Systems, methods, and apparatuses for two stage two-stage physical downlink control channel (PDCCH) with a downlink control information (DCI) flag and DCI format size indicator are described. For instance, the present disclosure presents an example method of wireless communication at a wireless device, which may include receiving, at a first bandwidth and during a transmission time interval (TTI), a first control channel message. In addition, the example method may include determining, based on a flag in the first control channel message, whether a second control channel message is present in the TTI. Furthermore, the example method may include receiving, at a second bandwidth, the second control channel message where the flag indicates that the second control channel message is present for the TTI.
