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.
Claims30
A method for wireless communications, comprising:
- receiving a service via a component carrier, wherein the component carrier is in an unlicensed radio frequency spectrum band;
- determining that a clear channel assessment failed for a time interval associated with the component carrier;
- and
- measuring one or more signals transmitted on the component carrier to estimate channel state information of the component carrier in the unlicensed radio frequency spectrum band, the measuring being triggered when it is determined that the clear channel assessment failed.
An apparatus for wireless communications, comprising:
- means for receiving a service via a component carrier, wherein the component carrier is in an unlicensed radio frequency spectrum band;
- means for determining that a clear channel assessment failed for a time interval associated with the component carrier;
- and
- means for measuring one or more signals transmitted on the component carrier to estimate channel state information of the component carrier in the unlicensed radio frequency spectrum band, the measuring being triggered when it is determined that the clear channel assessment failed.
An apparatus for wireless communications, comprising:
- a processor;
- memory in electronic communication with the processor;
- and
- instructions stored in the memory, the instructions being executable by the processor to:
- receive a service via a component carrier, wherein the component carrier is in an unlicensed radio frequency spectrum band;
- determine that a clear channel assessment failed for a time interval associated with the component carrier;
- and
- measure one or more signals transmitted on the component carrier to estimate channel state information of the component carrier in the unlicensed radio frequency spectrum band, the measure triggered when it is determined that the clear channel assessment failed.
A non-transitory computer-readable medium storing computer-executable code for wireless communications, the code executable by a processor to:
- receive a service via a component carrier, wherein the component carrier is in an unlicensed radio frequency spectrum band;
- determine that a clear channel assessment failed for a time interval associated with the component carrier;
- and
- measure one or more signals transmitted on the component carrier to estimate channel state information of the component carrier in the unlicensed radio frequency spectrum band, the measure triggered when it is determined that the clear channel assessment failed.
