Abstract
Aspects described herein relate to determining to transmit, at a first time instance, a burst of multiple sensing signals in an unlicensed frequency band, transmitting, at a second time instance, a reservation signal in the unlicensed frequency band to reserve resources in the unlicensed frequency band for at least one of the multiple sensing signals, and transmitting, based on transmitting the reservation signal, the at least one of the multiple sensing signals.
Claims18
An apparatus for wireless communication, comprising:
- a processor;
- memory coupled with the processor;
- and
- instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
- determine to transmit, at a first time instance, a burst of multiple sensing signals in an unlicensed frequency band;
- transmit, at a second time instance, a reservation signal in the unlicensed frequency band to reserve resources in the unlicensed frequency band for at least one of the multiple sensing signals, the reservation signal being transmitted at least in part by ramping up a transmit power to a second transmit power in a transmission gap following transmission of a previous sensing signal in the burst of multiple sensing signals, the second transmit power being greater than a first transmit power used to transmit the at least one of the multiple sensing signals;
- and
- transmit, based on transmitting the reservation signal, the at least one of the multiple sensing signals at least in part by ramping down the transmit power to the first transmit power in a second transmission gap following transmission of the reservation signal.
