Problems solved by technology

For example, there may be a time gap between the time when the UE can receive CSI RS for estimating CSI and the time when the base station can send data to the UE using the CSI report from the UE
Furthermore, when channel conditions change (e.g., when the UE moves relative to the base station or when interference conditions change), the CSI may be out of date by the time the base station can transmit data
Therefore, in this case, the base station cannot receive or determine reliable information of the current channel conditions to adapt the transmissions to reliable communications, such as reliable communications with high data rates

Abstract

This disclosure provides systems, methods, and apparatus, including computer programs encoded on a computer storage medium, for wireless communication. In one or more aspects, a user equipment (UE) is configured to transmit capability information of the UE for channel state information (CSI) reporting. The UE is further configured to receive configuration information for CSI reporting from the base station. The configuration information indicates a CSI reference resource comprising a plurality of time units of a first type for CSI reference signal (CSIRS) monitoring, a CSI target resource comprising one or more time units of a second type for which channel state information is to be estimated, or both. The CSI target resource is later in time than the CSI reference resource. Other aspects and features are also claimed and described.

Description

technical field [0001] Aspects of the techniques discussed below relate to wireless communication systems in general, and more particularly, but not limited to, configuring channel state information (CSI) reference resources, CSI target resources, or both. The discussed techniques can help achieve reliable high data rates and achieve overall improved system performance and user experience through improved mobility support. Background technique [0002] Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcast, and the like. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing the available network resources. Such networks, usually multiple-access networks, support the communication of multiple users by sharing the available network resources. [0003] A wireless communication network may include multiple base stations (BS, nodeBs, e...
