Abstract
An access point (AP) having full duplex (FD) capabilities transmits a trigger frame to cause at least a first station (STA) to initiate an uplink (UL) reference frame to the AP, the trigger frame further causing at least one second STA to obtain a signal strength measurement during transmission of the UL reference frame, and the AP receives from the at least one second STA, a reporting frame containing information about the signal strength measurement.
Claims24
A method comprising:
- transmitting, by an access point (AP) having full duplex (FD) capabilities, a trigger frame to cause at least a first station (STA) that is an intended recipient of the trigger frame to initiate an uplink (UL) transmission including a UL reference frame to the AP immediately after a short interframe space (SIFS) from an end of the trigger frame, the trigger frame further causing at least one second STA that overhears the UL transmission established between the AP and at least the first STA to obtain a signal strength measurement during the UL transmission of the UL reference frame transmitted from at least the first STA and intended to be received by the AP;
- and
- receiving, by the AP from the at least one second STA, a reporting frame containing information about the signal strength measurement.
A method comprising:
- in response to receipt of a trigger frame from an access point (AP), obtaining, by a second station (STA), a signal strength measurement during UL transmission of a first uplink (UL) reference frame transmitted from a first STA and intended to be received by the AP immediately after a short interframe space (SIFS) from an end of the trigger frame, wherein the first STA is an intended recipient of the trigger frame, and the second STA overhears the UL transmission established between the AP and the first STA;
- and
- transmitting, to the AP, a reporting frame containing information about the signal strength measurement.
An access point (AP) having full duplex (FD) capabilities, the AP comprising:
- a communications interface for wireless communications with at least a first and a second station (STA);
- and
- a processor configured to execute instructions to cause the AP to:
- transmit a trigger frame, the trigger frame causing at least the first STA that is an intended recipient of the trigger frame to initiate transmission of an uplink (UL) reference frame to the AP immediately after a short interframe space (SIFS) from an end of the trigger frame, the trigger frame further causing at least the second STA that overhears the UL transmission established between the AP and at least the first STA to obtain a signal strength measurement during the UL transmission of the UL reference frame transmitted from at least the first STA and intended to be received by the AP;
- and
- receive, from at least the second STA, a reporting frame containing information about the signal strength measurement.

A first station (STA) comprising:
- a communications interface for wireless communications with an access point (AP);
- and
- a processor configured to execute instructions to cause the first STA to:
- in response to receipt of a trigger frame from the AP, obtain a signal strength measurement during transmission of a first uplink (UL) reference frame transmitted from a second STA and intended to be received by the AP immediately after a short interframe space (SIFS) from an end of the trigger frame, wherein the first STA overhears the transmission established between the AP and the first STA, and the second STA is an intended recipient of the trigger frame;
- and
- transmit, to the AP, a reporting frame containing information about the signal strength measurement.
