Abstract
A node in a wireless communication system includes a transceiver that operates according to a first radio access technology (RAT). The transceiver is to measure a medium usage by one or more other nodes that operate according to a second RAT. The transceiver alternately transmits in a first time interval and bypasses transmission in a second time interval. The first and second time intervals repeat with a duty cycle. The transceiver is to puncture the first time interval with one or more silent gaps. The node also includes a processor to determine a duration of the one or more silent gaps is based on the medium usage.

A method comprising:
- measuring, at a first node that operates according to a first radio access technology (RAT), a medium usage by at least one second node that operates according to a second RAT, wherein the first node alternately transmits in a first time interval and bypasses transmission in a second time interval, the first and second time intervals repeat with a duty cycle;
- puncturing the first time interval with at least one silent gap, wherein a duration of the at least one silent gap is determined based on the medium usage;
- and
- modifying a percentage of the duty cycle allocated to the first time interval in response to changing the duration of the at least one silent gap.
An apparatus, comprising:
- a transceiver that operates according to a first radio access technology (RAT), wherein the transceiver is to measure a medium usage by at least one node that operates according to a second RAT, wherein the transceiver alternately transmits in a first time interval and bypasses transmission in a second time interval, wherein the first and second time intervals repeat with a duty cycle, and wherein the transceiver is to puncture the first time interval with at least one silent gap;
- and
- a processor to determine a duration of the at least one silent gap is based on the medium usage, wherein the processor is to modify a percentage of the duty cycle allocated to the first time interval in response to changing the duration of the at least one silent.
