Abstract: Certain aspects relate to methods and apparatus for discovering whether one or more enhanced capabilities are supported by devices (e.g., user equipment (UE), base station (BS), etc.) in a network. The enhanced capabilities may include, for example, the ability to support certain low latency procedures, enhanced component carrier (eCC) capability, and the like. The devices in the network may perform one or more handover-related procedures (e.g., cell selection/reselection, make-before-break handover, etc.) and/or other procedures (e.g., QoS negotiation, etc.) based, at least in part, on support for the one or more enhanced capabilities.

Abstract: A method of wireless communication includes transmitting channel state information reference signal (CSI-RS) configuration information to a user equipment (UE). The CSI-RS configuration information is transmitted so that the UE may mitigate interference caused by interfering CSI-RSs. The CSI-RS configuration may be a CSI-RS configuration of a neighbor cell.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node may receive a configuration corresponding to one or more channel state information (CSI) report settings associated with a reference signal resource set. The network node may transmit at least one CSI report that indicates a primary set of CSI measurements, of a plurality of CSI measurements associated with the reference signal resource set, and a secondary set of CSI measurements of the plurality of CSI measurements, wherein the plurality of CSI measurements comprises at least one of a physical layer reference signal received power (RSRP) value or a physical layer signal-to-interference-plus-noise ratio (SINR), and wherein the primary set of CSI measurements comprises at least one of a strongest RSRP value or a strongest SINR associated with the plurality of CSI measurements. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for channel estimation based on transmission spatial information. An example method of wireless communication by a user equipment includes receiving an indication of transmission spatial information associated with a network entity; receiving a reference signal from the network entity based on the transmission spatial information; and transmitting, to the network entity, channel state information (CSI) based on the received reference signal and the transmission spatial information.

Abstract: A method of wireless communication by a user equipment (UE), includes estimating a downlink channel to generate a channel estimate. The method also includes obtaining multiple precoding matrices, by a channel state information (CSI) module including a neural network encoder decoder pair, based on the channel estimate and multiple different multiple input multiple output (MIMO) ranks. The method further includes determining a best rank indicator based on the precoding matrices and spectral efficiency estimates for the different MIMO ranks. The method still further includes reporting, to a base station, the best rank indicator, a channel quality index (CQI), and CSI encoder output.

Abstract: A method for wireless communication by a user equipment (UE), includes receiving, from a base station, a reference signal (RS) on a set of resource elements (REs), the RS having been multiplexed onto the set of REs based on a non-orthogonal cover code, and a number of REs in the set of REs being less than a number of ports associated with the RS. The method further includes estimating, at the UE via a channel estimation neural network, a channel based on receiving the RS. The method still further includes transmitting, to the base station, a feedback report associated with the estimated channel based on receiving the RS.

Abstract: Disclosed are techniques for communication. In an aspect, a wireless node receives a configuration associated with one or more reference signal for positioning (RS-P) resources from a position estimation entity. The wireless node performs measurement(s) of a set of RS-P resources, and derives measurement information associated with a first virtual instance of the one or more RS-P resources based on the measurement(s). The wireless node transmits a measurement report comprising the measurement information to the position estimation entity.
