Abstract: A method and wireless communication system may be used for transferring management information. An access point (AP) may transmit a management information base (MIB) information request including a category field and an action details field to a wireless transmit/receive (WTRU). In response to receiving the information request, the WTRU may determine whether or not to provide management information to the AP. When the WTRU provides management information to the AP, the WTRU may compile management information stored in a MIB located in the WTRU and transmit a MIB information report to the AP. The MIB may list a plurality of tables containing information associated with radio resource management (RRM) and at least one table containing physical layer measurements. The AP may include a MIB for storing MIB information of the WTRU. The AP may transmit the stored MIB information of the WTRU in response to a request.

Abstract: A correct escape mechanism is determined according to interference type. Transmission is arranged so that interference may be measured at all time slots as needed to compute a measure of variance in interference in time slots (45). If the variance is above a predetermined value (62), time division duplex escape mechanisms are employed. If the variance is below a predetermined value, appropriate escape mechanisms are employed depending on whether the escape mechanism is being implemented during an uplink (324) or downlink (64). Interference causing FDD WTUs may be handed over to carrier bands to control interference experienced by TDD users.

Abstract: A temporary (temp) dedicated channel (DCH) is used to support communications. The temp-DCH channel is a channel that is assigned to a user having a set duration. After the duration expires, the channel is automatically released to the user. Embodiments of the invention relate to establishing the temp-DCH channel, determining the data rate and duration of the channel. Other embodiments relate to establishing back-to-back temp-DCH channels and the implementation details of these embodiments. Additionally, one embodiment relates to adding a start/stop function to the medium access controller which can be used in conjunction with temp-DCH as well as other applications.

Abstract: A temporary (temp) dedicated channel (DCH) is used to support communications . The temp-DCH channel is a channel that is assigned to a user having a set duration (fig 1). After the duration expires, the channel is automatically released to the user. Embodiments of the invention relate to establishing th e temp-DCH channel (fig 3), determining the data rate and duration of the channel. Other embodiments relate to establishing back-to-back temp-DCH channels and the implementation details of these embodiments. Additionally, one embodiment relates to adding a start/stop function to the medium access controller which can be used in conjunction with temp-DCH as well as other applications.

Abstract: A method and wireless communication system for transferring management information is shown in figure 1B below. The system includes at least one access point (AP) (110) including a first management entity (150) and a second management entity (155), and at least one wireless transmit/receive unit (WTRU) (105) including a third management entity (165) and a fourth management entity (170). The AP transmits a management information base (MIB) information request action frame including a category field and an action details field to the WTRU. In response to receiving the information request action frame, the WTRU determines whether or not to provide management information to the AP. When the WTRU provides management information to the AP, the WTRU compiles management information stored in a MIB located in the WTRU and transmits a MIB information report action frame to the AP.

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: In a wireless communication system including an access point and at least one wireless transmit/receive unit (WTRU), a method for adaptive radio resource management begins by examining a frame error rate value of a WTRU. Then, a channel utilization value of the WTRU and a current data rate of the WTRU are examined. System parameters for the WTRU are adjusted based on the examined variables.
