Abstract

See full text

Techniques are described for wireless communication. A first method may include determining a pattern of signal transmissions for transmitting instances of a signal in a time period of an unlicensed radio frequency spectrum band; determining whether the unlicensed radio frequency spectrum band is unavailable to transmit at least one instance of the signal; and changing, in response to determining the unlicensed radio frequency spectrum band is unavailable to transmit an instance of the signal, the pattern of signal transmissions for the time period. A second method may include identifying at least one reference signal pattern from a plurality of reference signal patterns based at least in part on whether a plurality of transmission time intervals are bundled; and signaling the identified at least one reference signal pattern to a device.
