A method and apparatus may be used for network management via MAC measurements. The measurements may include WTRU uplink traffic loading measurement, and an AP service loading measurement. The measurements may be applicable to at least to layers 1 and 2 as applied to, for example, 802.11k in the context of OFDM and CDMA 2000 systems, but may be applicable to other scenarios as well. A method for determining and transmitting congestion information may be provided for a Wireless Local Area Network (WLAN) system. The method and apparatus may be used for managing congestion when congestion is detected. The method and apparatus may be used in wireless systems that use a Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) mechanism. The methods may be implemented in wireless transmit/receive units (WTRU)s and access points (AP)s of various forms.

An Institute of Electrical and Electronics Engineers (IEEE) 802.11 station (STA) comprising:a receiver configured to receive, from an access point (AP), a beacon frame that includes a field that is 8 bits in length and represents an average access delay associated with the AP, wherein the average access delay is a measurement of time between when a packet is ready for transmission and an actual packet transmission start time; anda processor configured to decode the beacon frame including the field.2. The IEEE 802.11 STA of claim 1 , wherein the 8 bits represent a scaled indication of the average access delay associated with the AP.3. The IEEE 802.11 STA of claim 2 , wherein the 8 bit representation includes values from 1 to 252.4. The IEEE 802.11 STA of claim 1 , wherein the receiver is configured to receive a plurality of fields representing an average access delay from a plurality of APs respectively claim 1 , and the processor is further configured to select one AP from the plurality of APs a based on the plurality of fields.5.

Systems, methods, and instrumentalities are disclosed that may provide assistance across networks using different radio access technologies. A centralized gateway (CGW) may be provided to facilitate the assistance via client devices in the networks. The CGW and client devices may use a common protocol and common interface to take actions relating to the assistance. 114-. (canceled)15. A method of managing communications among devices , the method comprising:broadcasting, by an access point, AP, that is configured for communication via a first radio access technology, RAT, and a second RAT, an indication that the AP is capable of communicating via the first RAT and the second RAT, wherein the AP includes a management entity that is common to the first RAT and the second RAT;receiving, via the first RAT, an attachment request indicative of a station, STA, that is configured to communicate via the first RAT and the second RAT; andtransmitting, responsive to the attachment request, an attachment response via the first RAT, wherein the attachment response indicates an operating mode change for the STA.16. The method of claim 15 , wherein broadcasting the indication is performed periodically.17. The method of claim 15 , wherein the attachment request indicates that the STA is configured to operate the first RAT and the second RAT simultaneously.18. The method of claim 15 , wherein the operating mode change includes the STA switching from communicating with the AP via the first RAT claim 15 , to communicating with the AP via the second RAT.19. The method of claim 15 , wherein the operating mode change includes activating the second RAT on the STA.20. The method of claim 15 , wherein the first RAT corresponds to 2.4 GHz and the second RAT corresponds to 60 GHz.21. An access point claim 15 , AP claim 15 , that is configured for communication via a first radio access technology claim 15 , RAT claim 15 , and a second RAT claim 15 , the AP comprising:a management entity that is ...
