Abstract: Certain aspects of the present disclosure provide techniques for transmitting and processing channel state information (CSI) reference signals (CSI-RS). An exemplary method includes determining a configuration of channel state information reference signals (CSI-RSs), wherein the configuration indicates a set of resource elements (REs) to be used for CSI-RSs and a first mapping of CSI-RS ports to the set of REs; sending an indication of the configuration of the CSI-RSs; and transmitting the CSI-RSs according to the determined configuration.

Abstract: Aspects of the present disclosure provide a wireless device that communicates with another wireless device utilizing self-contained subframes. The wireless device communicates with a scheduling entity utilizing a plurality of self-contained subframes that include a first subframe and a second subframe. Each of the self-contained subframes includes an uplink (UL) portion and a downlink (DL) portion. The wireless device further receives DL control information from the scheduling entity in the DL portion of the first subframe, and transmits UL data that includes a plurality of reference signal bursts to the scheduling entity in the UL portion of the first subframe. The plurality of reference signal bursts are uniformly spaced in at least a portion of the UL portion of the first subframe.

Abstract: A control resource region of an New Radio system slot structure may be separated into control resource sets, only some of which may be used for control transmissions. Aspects presented herein improve the efficient utilization of resources by enabling data transmission in resources of the DL control resource region and/or the UL control resource region. A UE receives an indication of a control resource set in a control resource region of a slot that may provide a control channel resource or a data channel resource and performs rate matching for data transmissions in the data channel based at least in part on the indication. The indication may be a semi-static indication, e.g., RRC signaling, of the control resource set.

Abstract: Various additional and alternative aspects are described herein. In some aspects, the present disclosure provides a method for wireless communication. The method includes determining at least one RS pattern for allocating a reference signal on an uplink channel and a downlink channel based on one or more transmission factors for transmitting the reference signal, wherein at least a portion of the at least one RS pattern is the same for the uplink channel and the downlink channel. The method further includes transmitting the reference signal using the determined RS pattern.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a base station. The base station estimates a first channel matrix observed by a first UE. The base station also applies a SVD to the first channel matrix to obtain a left singular vector matrix and a right singular vector matrix of the first channel matrix. The base station further determines a first precoding matrix based on a product of the right singular vector matrix and a conjugate transpose of the left singular vector matrix. The base station yet further applies the first precoding matrix to at least one first symbol to generate one or more precoded symbols. The base station transmits the one or more precoded symbols.

Abstract: This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for FL model update reporting based on UE clustering. A UE may receive, from a base station, one or more criteria for grouping a plurality of UEs into a UE group for a combined machine learning model update. The UE may receive, from one or more UEs in the UE group, individual machine learning model updates for a machine learning model and transmit the combined machine learning model update to the base station based on the individual machine learning model updates from the one or more UEs.
