Abstract: A method for neighbor scanning in a wireless local area network having a station, a first access point (AP) to which the station is associated, and a second AP begins by generating timing information regarding a beacon signal sent by the second AP. The timing information is reported from the first AP to the station. The station schedules a time, based on the timing information, to listen for the beacon signal transmitted by the second AP.

Abstract: A method and system for managing association and disassociation of a wireless transmit/receive unit (WTRU) to an access point (AP) in a wireless communication system is disclosed. Once the AP detects that a WTRU is in an inactive state for a predetermined period of time, the AP transmits an association confirmation request message to the WTRU. If the AP receives an acknowledgement (ACK) responsive to the association confirmation request message, the AP maintains the association with the WTRU. If the AP fails to receive an ACK, the AP disassociates the WTRU.

Abstract: An improved method of network management, particularly in the context of standards IEEE802.11 and IEEE802.11k, through two new MAC measurements, with attendant advantages. The two new measurements include WTRU uplink traffic loading measurement, and an AP service loading measurement and is generally applicable at least to layers 1 and 2 as applied to a least 802.11k in the context of OFDM and CDMA 2000 systems, but is applicable to other scenarios as well. A Method for determining and advertising congestion is also provided for a Wireless Local Area Network (WLAN) system. The present invention also introduces a method for managing congestion when congestion is detected. This aspect of the present invention applies primarily to wireless systems that use the Carrier Sense Multiple Access/ Collision Avoidance (CSMA/CA) mechanism. The methods are advantageously implemented in selectively configured WTRUs of various forms.

Abstract: Systems and methods for integrating bandwidth management (BWM) equipment into a network in order to manage the use of bandwidth over multiple radio access technologies (RATs) relating to communications between a wireless transmit receive unit and a mobile core network (MCN). When integrating itself into the network, a BWM server may be placed between a MCN and an femto access point. In order for WTRUs to communicate with the MCN through the femto acces point and a BWM server, a BWM server may need deep packet inspection capabilities.

Abstract: A method and apparatus for operating supplementary cells in licensed exempt (LE) spectrum. An aggregating cell operating in a frequency division duplex (FDD) licensed spectrum is aggregated with a LE supplementary cell operating in a time sharing mode for uplink (UL) and downlink (DL) operations. The LE supplementary cell may be an FDD supplementary cell dynamically configurable between an UL only mode, a DL only mode, and a shared mode, to match requested UL and DL traffic ratios. The LE supplementary cell may be a time division duplex (TDD) supplementary cell. The TDD supplementary cell may be dynamically configurable between multiple TDD configurations. A coexistence capability for coordinating operations between the LE supplementary cell with other systems operating in the same channel is provided. Coexistence gaps are provided to measure primary/secondary user usage and permit other systems operating in the LE supplementary cell channel to access the channel.
