Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for reporting configurations for neural network-based processing at a UE. A network entity may transmit to the UE a CSI configuration that includes one or more parameters for a neural network and one or more reference signals. The EE may measure the one or more reference signals based on the CSI configuration. A CSI may be based on the one or more parameters and the measurement of the one or more reference signals. The UE may report the CSI to the network entity based on output of the neural network.

Abstract: In an aspect, a UE obtains information (e.g., UE-specific information) associated with a set of triggering criteria (e.g., from a server, a serving network, e.g., in conjunction with or separate from a set of neural network functions) for a set of neural network functions. The UE obtains positioning measurement data associated with a location of the UE, and processes the positioning measurement data into a respective set of positioning measurement features based at least in part upon the positioning measurement data and at least one neural network function from the set of neural network functions that is triggered by at least one triggering criterion from the set of triggering criteria. The UE reports the processed set of positioning measurement features to a network component (e.g., BS, LMF, etc.).

Abstract: Methods, systems, and devices for wireless communications are described that support channel state information (CSI) determination and reporting techniques. A CSI resource set may be configured by a base station to include two or more CSI resources for a UE. The UE may measure two or more CSI reference signals (CSI-RSs) in the CSI resources, and perform beam selection across the two or more CSI resources. If the UE selects two or more beams for communications with the base station that are within different CSI resources, the UE may provide an indication of the selected beams. If the UE selects a beam for communications within one CSI resource, the UE may provide an indication of the resource index and port selection associated with the CSI resource.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit feedback to a base station indicating phase values for sub-bands in a bandwidth part (BWP). The base station may use the phase feedback to perform precoding on a set of beams. To support a reduced payload overhead for the feedback, the UE may implement differential phase feedback. For example, the UE may divide the BWP into a number of sub-band groups and may generate, for each sub-band group of each beam, a first set of bits indicating an absolute phase value for a first sub-band of the sub-band group. The UE may additionally generate a second set of bits indicating differential phase values for the other sub-bands of each sub-band group. The UE may report the first and second sets of bits for the beams to the base station for precoding.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for sounding reference signal (SRS) guided downlink channel state information-reference signal (CSI-RS) scan. One example method for wireless communication generally includes determining whether to perform channel estimation operations for a user-equipment (UE) using a reciprocity-based scheme or a channel state information-reference signal (CSI-RS) based scheme based on a criteria of a cell, and performing the channel estimation operations based on the determination.

Abstract: Various aspects are described for an enhanced power headroom report (PHR) for feeding back beamformed sounding reference signal (SRS) power scaling. Beamformed SRS along directions where a user equipment (UE) can best nullify interference/maximize downlink (DL) signal to interference plus noise ratio (SINR) would be very helpful for DL beamforming. SRS beamforming requires additional support, if rank related decisions are being made at eNB. For example, power normalization factors need to be sent or reported on the uplink (UL) to eNB. This disclosure provides examples of how the PHR on the uplink can be used to do such reporting. There are two types of PHR being proposed, one nominal for the UL-oriented SRS, like LTE-style PHR, and one for the DL-oriented SRS where the UE also reports or indicates the power normalization factors of each SRS port.

Abstract: Aspects of the present disclosure disclose techniques for the indication of the allocation of the downlink (DL) demodulation reference signal (DM-RS) ports for the data channel in NR communications. In some examples, the channel state information (CSI) reference signal (CSI-RS) may be associated with a corresponding DM-RS for a DL data channel. The transmitting device, in some examples, may further transmit a notification that provides resource allocations (e.g., port allocations) that minimize the redundant information that is required to be transmitted from the base station to the user equipment (UE) when the DM-RS port allocation is the same as the CSI-RS port allocation received by the UE in an earlier time slot.

Abstract: Aspects of the present disclosure provide methods and apparatuses that can utilize different subframe structures to estimate a channel during wireless communication in different scenarios. When a scheduling entity determines that a scheduled entity is near or at a cell edge, the scheduled entity may use a special subframe to estimate the channel utilizing more resources of the subframe, for example data signals. The special subframe can facilitate channel estimation by using a less complex (or lower rank) modulation and coding scheme (MCS) for the data symbols than a normal subframe for other scheduled entities not located near the cell edge.

Abstract translation: 本公开的各方面提供了可以在不同情况下利用不同子帧结构来估计无线通信期间的信道的方法和设备。 当调度实体确定调度实体接近或位于小区边缘时，调度实体可以使用特殊子帧来利用该子帧的更多资源（例如数据信号）来估计信道。 特殊子帧可以通过针对数据符号使用较不位于小区边缘附近的其他调度实体的正常子帧的较不复杂（或较低等级）调制和编码方案（MCS）来促进信道估计。
