For proper beam failure detection or beam failure recovery even when a plurality of transmission points are used, an aspect of user equipment of the present disclosure includes: a receiving section configured to receive information regarding a number or proportion of at least one of a beam, a link, and a reference signal used to specify partial beam failure detection with respect to one or more transmission/reception points; and a control section configured to perform partial beam failure detection at one or a plurality of transmission/reception points based on the information.

A coding method includes: reporting N PMIs to a network device; where each PMI is corresponding to one channel; a first PMI includes channel information of a channel corresponding to a second PMI; and the first PMI is one of the N PMIs, the second PMI is at least one PMI before the first PMI, and N is a positive integer greater than 1.

Certain aspects of the present disclosure provide techniques for reporting beam-strength related Type-II channel state information (CSI) coefficient feedback.

A wireless user equipment (UE) may employ any of various mechanisms for reporting signal quality measurements to a wireless network. The UE may impose a time delay between measurement and reporting, based on a delay parameter K. The UE may average measurements obtained at different measurement instances. The UE may employ any of various schemes for prioritizing transmission of one type of report over another, when temporal collisions occur between different types of report. The UE may employ a differential report that includes a state for indicating that a beam is not workable. The UE may employ a beam index that includes a state for indicating an invalid beam. A base station may receive a signal quality report and determine workability of a beam, e.g., by triggering a report of channel state information.

Apparatuses, methods, and systems are disclosed for reporting channel state information for high speed devices. One method (800) includes receiving (802) an indication of a high-speed channel state information framework. The method (800) includes receiving (804) a channel state information reporting configuration corresponding to high-speed devices. The method (800) includes receiving (806) channel state information reference signal resources based on a channel state information reference signal resource configuration. The method (800) includes generating (808) at least one channel state information report based on at least one measurement, at least one configuration, and/or at least one indication according to the channel state information reporting configuration. The at least one channel state information report includes a first part and a second part, and the second part includes at least one group. The method (800) includes reporting (810) the at least one channel state information report to a network.

A system described herein may determine transformations, differences, variations, etc. in radio frequency (“RF”) waveforms sent by a device in order to detect motion-based events. Models associated with the differences in such RF waveforms may be used to identify particular types of events, such as the presence of an individual in a room or other area, a type of motion, or other types of events. An interval or rate at which the device outputs RF waveforms may be modified, in order to increase the resolution of the determination of differences between the RF waveforms as sent and the RF waveforms as received, and/or to conserve power.

In one aspect, a method of wireless communication includes generating, by a user equipment (UE), a delta precoding value for a precoding matrix update, the delta precoding value relative to a previous precoding matrix. The method also includes generating, by the UE, a delta power loading value for the precoding matrix update, the delta power loading value relative to the previous precoding matrix. The method further includes transmitting, by the UE, a transmission indicating the delta precoding value and the delta power loading value. Other aspects and features are also claimed and described.

A method comprises: configuring multiple reporting modes for multi-level based transmitter (TX) beam index reporting for a particular beam/antenna panel group from a plurality of beam/antenna groups, wherein the multiple reporting modes includes at least one of a full reporting mode configuration for the particular beam/antenna panel group, a full reporting mode configuration common for the plurality of beam/antenna panel groups, a differential reporting mode, and a partial reporting mode, selecting a reporting mode from the multiple reporting modes, and sending a report based on the selected reporting mode.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to report first channel state information (CSI), wherein the first CSI is associated with a parameter that indicates a priority of the first CSI. The UE may prioritize the first CSI over a second CSI based at least in part on the parameter. The UE may transmit an indication of the first CSI and may drop the second CSI based at least in part on prioritizing the first CSI over the second CSI. Numerous other aspects are provided.

Provided are a method and device for reporting channel state information (CSI), a method and device for processing channel state information, and a storage medium. The method for reporting channel state information includes: dividing M subbands to be reported into two sets; determining a relative value between CSI of each subband in a second set and CSI of a reference subband corresponding to the each subband in the second set; and reporting CSI of each subband in a first set and the relative value of the each subband in the second set to a base station.
