Apparatus and method for promoting in-device coexistence between Wi-Fi and ultra-wide band communication

A device comprising:

• a memory configured to store instructions;
• and
• a processor operably connected to the memory, the processor configured, when executing the instructions, to:
• determine one or more active slots and inactive slots in an ultra-wide band (UWB) ranging round;
• determine multiple silent periods in the ranging round based on an arrangement of the inactive slots by (i) determining multiple sets of contiguous inactive slots in the ranging round and (ii) grouping each set of contiguous inactive slots into one of the multiple silent periods;
• determine a target silent period in the ranging round, among the multiple silent periods, to be used for WiFi communication;
• determine multiple target wake time (TWT) parameters such that a TWT session period defined by the TWT parameters overlaps with the target silent period;
• determine one or more second silent periods preceding the target silent period in which the TWT parameters can be negotiated with an access point (AP) for the WiFi communication;
• and
• negotiate the TWT parameters with the AP during the one or more second silent periods.

A non-transitory computer readable medium comprising a plurality of instructions that, when executed by at least one processor, is configured to cause the at least one processor to:

• determine one or more active slots and inactive slots in an ultra-wide band (UWB) ranging round;
• determine multiple silent periods in the ranging round based on an arrangement of the inactive slots by (i) determining multiple sets of contiguous inactive slots in the ranging round and (ii) grouping each set of contiguous inactive slots into one of the multiple silent periods;
• determine a target silent period in the ranging round, among the multiple silent periods, to be used for WiFi communication;
• determine multiple target wake time (TWT) parameters such that a TWT session period defined by the TWT parameters overlaps with the target silent period;
• determine one or more second silent periods preceding the target silent period in which the TWT parameters can be negotiated with an access point (AP) for the WiFi communication;
• and
• negotiate the TWT parameters with the AP during the one or more second silent periods.
