Abstract
Techniques are described for wireless communication. One technique includes receiving a service via a component carrier, wherein the component carrier may be in an unlicensed radio frequency spectrum band. One or more signals transmitted on the component carrier may be measured to estimate channel state information of the component carrier in the unlicensed radio frequency spectrum band.
Claims20
A method of wireless communication at a user equipment (UE), comprising:
- receiving downlink control information (DCI), the DCI including a trigger;
- determining, based at least in part on the trigger, a channel state information (CSI) subframe value;
- selecting, based at least in part on the determined CSI subframe value, a CSI subframe associated with reporting a CSI;
- and
- transmitting the CSI in the selected CSI subframe.
An apparatus for wireless communication at a user equipment (UE), comprising:
- a processor,
- memory coupled with the processor;
- and
- instructions stored in the memory and executable by the processor to cause the apparatus to:
- receive downlink control information (DCI), the DCI including a trigger;
- determine, based at least in part on the trigger, a channel state information (CSI) subframe value;
- select, based at least in part on the determined CSI subframe value, a CSI subframe associated with reporting a CSI;
- and
- transmit the CSI in the selected CSI subframe.
A non-transitory computer-readable medium storing code for wireless communication at a user equipment (UE), the code comprising instructions executable by a processor to:
- receive downlink control information (DCI), the DCI including a trigger;
- determine, based at least in part on the trigger, a channel state information (CSI) subframe value;
- select, based at least in part on the determined CSI subframe value, a CSI subframe associated with reporting a CSI;
- and
- transmit the CSI in the selected CSI subframe.
