Claim of US Patent No. 10,397,915

1. A method for wireless communication, comprising:determining whether to use a first timing configuration or a second timing configuration for communication in an unlicensed radio frequency spectrum band, the first timing configuration having a first time difference between a downlink communication and a responsive uplink communication, and the second timing configuration having a second time difference between the downlink communication and the responsive uplink communication, the second time difference being less than the first time difference;
receiving a control message from a base station during a transmission opportunity (TxOp) of the unlicensed radio frequency spectrum band; and
transmitting an uplink message during the TxOp in response to the control message, wherein the uplink message comprises a channel state information (CSI) report based at least in part on the first timing configuration or the second timing configuration.
