Definitions

• Wireless communications systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing the available system resources (e.g., time, frequency, and power).
• system resources e.g., time, frequency, and power.
• the method also may involve determining a clock drift value based at least in part on the mutual clock drift.
• the clock drift value may be compared to the guard interval, and sending the communication may be performed when the clock drift value is within a threshold value of the guard interval.
• An apparatus for wireless communication also is described.
• the apparatus may include: means for identifying a guard interval for a first wireless communication device (WCD) having coexisting radios that use different radio access technologies (RATs); and, means for apply ing the identified guard interval before and after a start of a scheduled interference interval for the first WCD.
• the guard interval may define a non-transmission time interval to the first WCD,
• the apparatus may include these and other features to carry out the functions described above and further herein.

• the mutual clock drift may result in a portion (e.g. , subframes) of the WLAN Tx 290-b colliding with communications via the different RAT occurring during the scheduled Rx/Tx interval 295-b (illustrated by the overlap in time).
• the overlapping portion of the WLAN Tx 290 may not be successfully received by the STA.
• FIG, SA shows a block diagram 500-a of a device 505 for use in a station for wireless communication, in accordance with various aspects of the present disclosure.
