Abstract
An Access Point (AP) 402 and a method therein for Multi-User Clear-To-Send (MU CTS) signaling between the AP and at least one wireless station (STA) 404,406. The AP sends a Request To Send (RTS) packet directed to multiple STAs. The RTS packet is indicating at least two STAs, to which the AP would like to transmit, and a configuration of a CTS packet to be used by said at least two STAs when responding to the RTS packet. The configuration enables the AP to identify the at least two STAs when the at least two STAs are transmitting a respective CTS packet. Further the AP receives, from at least one STA, a respective CTS packet transmitted in accordance with the indicated configuration, thereby enabling the AP to identify the at least one STA transmitting the respective CTS packet.

63. A computer program product stored in a non-transitory computer readable medium for Multi-User Clear-To-Send (MU CTS) signaling between an Access Point (AP) and at least one wireless station (STA), the computer program product comprising software instructions which, when run on the processing circuitry of the AP, causes the AP to:
-
send a Request To Send (RTS) packet directed to multiple STAs, wherein the RTS packet indicates; at least two STAs to which the AP would like to transmit; and a configuration of a Clear To Send (CTS) packet to be used by the at least two STAs when responding to the RTS packet, the configuration enabling the AP to identify the at least two STAs when the at least two STAs are transmitting a respective CTS packet; and receive, from at least one STA, a respective CTS packet transmitted in accordance with the indicated configuration, thereby enabling the AP to identify the at least one STA transmitting the respective CTS packet.

64. A computer program product stored in a non-transitory computer readable medium for Multi-User Clear-To-Send (MU CTS) signaling between an Access Point (AP) and at least one wireless station (STA), the computer program product comprising software instructions which, when run on the processing circuitry of a first STA, causes the first STA to:
-
receive a Request To Send (RTS) packet from the AP, wherein the RTS packet indicates to the first STA; the STAs to which the AP would like to transmit; and a configuration of a Clear To Send (CTS) packet to be used by the at least two STAs when responding to the RTS packet, the configuration enabling the AP to identify the respective one of the at least two STAs when the at least two STAs are transmitting the CTS packets; and send, to the AP, a CTS packet in accordance with the indicated configuration, thereby enabling the AP to identify the first STA.
