==CHANNEL STATE INFORMATION (CSI) MEASUREMENTS AND CSI REPORTING IN LICENSED ASSISTED ACCESS (LAA) - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18340957 titled 'CHANNEL STATE INFORMATION (CSI) MEASUREMENTS AND CSI REPORTING IN LICENSED ASSISTED ACCESS (LAA)

==Simplified Explanation==

- The patent application discusses techniques for reporting channel state information (CSI).
- The techniques are specifically applicable to license assisted access (LAA) secondary cells (SCells).
- The user equipment (UE) apparatus described in the patent application can derive channel measurements based on reference signals in the subframes of the LAA SCell.
- The UE apparatus generates CSI that includes a channel quality indicator (CQI) based on the average of the channel measurements from multiple subframes.
- The CSI report generated by the UE apparatus indicates the set of CSI parameters.
- The patent application focuses on the specific occupancy of OFDM symbols in the first and second subframes, as well as the OFDM symbols between them.


==Original Abstract Submitted==

Techniques for channel state information (CSI) reporting are discussed. One example apparatus at a user equipment can derive, for one or more subframes of a license assisted access (LAA) secondary cell (SCell), one or more channel measurements based on reference signals (e.g., cell-specific reference signals (CRS) or CSI reference signals (CSI-RS)), in those subframes; generate CSI that comprises a channel quality indicator (CQI) based on an average of the one or more channel measurements from multiple subframes comprising a first subframe and a later second subframe, wherein each orthogonal frequency division multiplexing (OFDM) symbol of a second slot of the first subframe is occupied, wherein each of a first three OFDM symbols of the second subframe are occupied, and wherein each OFDM symbol between the first subframe and the second subframe is occupied; and generate a CSI report that indicates the set of CSI parameters.
