CHANNEL STATE INFORMATION REFERENCE SIGNAL FOR WIDEBAND OPERATION - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18349357 Titled 'CHANNEL STATE INFORMATION REFERENCE SIGNAL FOR WIDEBAND OPERATION'
Simplified Explanation
This disclosure presents systems, methods, and devices for determining whether a channel state information reference signal (CSI-RS) should be transmitted. It also provides a configuration for transmitting the CSI-RS on a wideband, based on the outcome of a listen-before-talk (LBT) operation in multiple sub-bands of the wideband. The base station can transmit information about sub-band availability before transmitting the CSI-RS, allowing the user equipment (UE) to determine if the CSI-RS will be transmitted and on which sub-bands. Rate matching configurations are provided based on the availability of sub-bands. Power configurations and resource element selection criteria are also provided for wideband CSI-RS and CSI feedback.
Original Abstract Submitted
This disclosure provides systems, methods, and apparatuses for determining whether a channel state information reference signal (CSI-RS) is to be transmitted, and a configuration for transmission of the CSI-RS on a wideband based on an outcome of a listen-before-talk (LBT) operation in multiple sub-bands of the wideband. In one aspect, a base station may transmit sub-band usage information indicating sub-band availability before the CSI-RS, thereby allowing a user equipment (UE) to determine whether the CSI-RS will be transmitted and, if so, on which sub-bands the CSI-RS will be transmitted. Furthermore, rate matching configurations are provided based on whether sub-band usage has been received, based on which sub-bands are available. Still further, power configurations and resource element selection criteria are provided for wideband CSI-RS and CSI feedback.
