  • Patent number: 11831371
    Abstract: Systems and methods disclosed herein use channel state information (CSI) reports from a user equipment (UE) having additional CSI beyond CSI directly derived according to a current MIMO configuration between a base station and the UE. In some embodiments, a channel quality indicator (CQI) according to a selected layer of a plurality of layers used to receive the MIMO transmission as determined relative to the MIMO transmission is reported. In some embodiments, a precoding matrix indicator (PMI) according to a selected layer of a plurality of layers useable to receive rank 1 transmissions is reported along with a CQI determined according to that layer, or according to a layer used to receive the MIMO transmission as determined relative to the MIMO transmission. In some embodiments, a base station configures a UE to report more fulsome CSI according to each of a plurality of ranks.

  • Publication number: 20230375947
    Abstract: Some implementations described herein include operating components in a lithography system at variable speeds to reduce, minimize, and/or prevent particle generation due to rubbing of or collision between contact parts of the components. In some implementations, a component in a path of transfer of a semiconductor substrate in the lithography system is operated at a relatively high movement speed through a first portion of an actuation operation, and is operated at a reduced movement speed (e.g., a movement speed that is less than the high movement speed) through a second portion of the actuation operation in which contact parts of the component are to interact. The reduced movement speed reduces the likelihood of particle generation and/or release from the contact parts when the contact parts interact, while the high movement speed provides a high semiconductor substrate throughput in the lithography system.
