INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract A method and apparatus may be used for assigning groups of stations in wireless communications to one or more groups. Groups may be assigned by an access point (AP) based on information received from a station (STA). Group information may be signaled to each station and a group identifier may be indicated in a frame. The group information may be applied to a performance enhancement, for example power savings for the station, wherein the station enters a power saving mode on a condition that the station determines that it is not a member of the group. ## Claims ### Claim 1 A wireless station (STA) comprising: a receiver configured to receive, from an access point (AP), a management frame that includes an indication of a group to which the STA is assigned; the receiver configured to receive a frame from the AP, wherein the frame comprises a data packet and a group identifier; a processor configured to determine whether the group identifier received in the frame corresponds to the indication of a group to which the STA is assigned; and the processor configured to enter a power saving mode on a condition that the group identifier received in the frame does not correspond to the indication of a group to which the STA is assigned. ### Claim 2 (depends on 1) The STA of claim 1, further comprising: a transmitter configured to transmit an indication of power save capabilities to the AP. ### Claim 3 (depends on 1) The STA of claim 1, further comprising: a transmitter configured to transmit power level information to the AP. ### Claim 4 (depends on 1) The STA of claim 1, further comprising: a transmitter configured to transmit a quality of service (QoS) requirement to the AP. ### Claim 5 (depends on 1) The STA of claim 1, wherein the group to which the STA is assigned is based on a load balancing algorithm of the AP. ### Claim 6 A method performed by a station (STA), the method comprising: receiving, from an access point (AP), a management frame that includes an indication of a group to which the STA is assigned; receiving a frame from the AP, wherein the frame comprises a data packet and a group identifier; determining whether the group identifier received in the frame corresponds to the indication of a group to which the STA is assigned; and entering a power saving mode on a condition that the group identifier received in the frame does not correspond to the indication of a group to which the STA is assigned. ### Claim 7 (depends on 6) The method of claim 6, further comprising: transmitting an indication of power save capabilities to the AP. ### Claim 8 (depends on 6) The method of claim 6, further comprising: transmitting power level information to the AP. ### Claim 9 (depends on 6) The method of claim 6, further comprising: transmitting a quality of service (QoS) requirement to the AP. ### Claim 10 (depends on 6) The method of claim 6, wherein the group to which the STA is assigned is based on a load balancing algorithm of the AP. ### Claim 11 An access point (AP) comprising: a receiver configured to receive capability information from a station (STA), wherein the first information indicates that the STA is power saving group capable; a processor configured to assign the STA to a group for power saving; a transmitter configured to transmit, to the STA, a management frame that includes an indication of the group to which the STA is assigned; and the transmitter configured to transmit, to the STA, a frame including a data packet and a group identifier to enable the STA to enter a power save mode on a condition that data packet is not intended for the group. ### Claim 12 (depends on 11) The AP of claim 11, wherein the receiver is further configured to receive traffic utilization information from the STA, and wherein the processor is further configured to assign the STA to a group based on the traffic utilization information. ### Claim 13 (depends on 11) The AP of claim 11, wherein the receiver is further configured to receive power level information from the STA, and wherein the processor is further configured to assign the STA to a group based on the power level information. ### Claim 14 (depends on 11) The AP of claim 11, wherein the receiver is further configured to receive a quality of service (QoS) requirement from the STA, and wherein the processor is further configured to assign the STA to a group based on the received QoS requirement.
