Techniques for transmitting patterns of signal transmissions or reference signals over an unlicensed radio frequency spectrum band

An apparatus for wireless communication, comprising:

• means for determining a pattern of signal transmissions for transmitting instances of a signal in a time period of an unlicensed radio frequency spectrum band, wherein the pattern of signal transmissions comprises a first scheduled signal transmission and a second scheduled signal transmission;
• means for determining whether the unlicensed radio frequency spectrum band is unavailable to transmit at least one instance of the signal;
• and
• means for 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, wherein the changing the pattern of signal transmissions comprises scheduling an additional signal transmission in the pattern of signal transmissions during a frame of the unlicensed radio frequency spectrum band occurring between the first scheduled signal transmission and the second scheduled signal transmission.

An apparatus for wireless communication, in a system comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• determine a pattern of signal transmissions for transmitting instances of a signal in a time period of an unlicensed radio frequency spectrum band, wherein the pattern of signal transmissions comprises a first scheduled signal transmission and a second scheduled signal transmission;
• determine whether the unlicensed radio frequency spectrum band is unavailable to transmit at least one instance of the signal;
• and
• change, 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, wherein the changing the pattern of signal transmissions comprises scheduling an additional signal transmission in the pattern of signal transmissions during a frame of the unlicensed radio frequency spectrum band occurring between the first scheduled signal transmission and the second scheduled signal transmission.

A non-transitory computer readable medium storing code for wireless communication, the code comprising instructions executable by a processor to:

• determine a pattern of signal transmissions for transmitting instances of a signal in a time period of an unlicensed radio frequency spectrum band, wherein the pattern of signal transmissions comprises a first scheduled signal transmission and a second scheduled signal transmission;
• determine whether the unlicensed radio frequency spectrum band is unavailable to transmit at least one instance of the signal;
• and
• change, 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, wherein the changing the pattern of signal transmissions comprises scheduling an additional signal transmission in the pattern of signal transmissions during a frame of the unlicensed radio frequency spectrum band occurring between the first scheduled signal transmission and the second scheduled signal transmission.
