摘要:
A radio resource control unit which monitors air interface resources, includes an air interface measurement unit for obtaining air interface measurements; a storage unit which stores air interface measurements and a corresponding timestamp; and a processing unit, for processing the air interface measurements. At least a portion of the interface measurements may be predicted values.

An air interface information unit including a measurement setup unit for implementing measurement setup procedures and configuration; a measurement reception and storing unit for storing actual, predicted and default air interface values and corresponding timestamps; a measurement processing unit for filtering, verifying, processing and combining air interface values; and a measurement output unit for providing air interface values to RRM functions upon request and triggering RRM functions when an air interface value exceeds a predetermined threshold.
摘要:
A startup process of an access point (AP) includes a discovery phase and an announcement phase. During the discovery phase, the AP detects neighboring APs from its own extended service set (ESS), neighboring APs from different ESSs, and external sources of interference. During the announcement phase, the AP transmits its beacon signals at maximum power in order to accelerate recognition by neighboring APs running the discovery phase. An automatic initialization channel selection process of an AP scans channels the AP will use to communicate. Information of each scanned channel is recorded and a best performance channel is determined for use by the AP.

摘要:
A method for determining values for use by radio resource management functions is disclosed. Air interface actual values and predictive values are obtained and stored. A timestamp indicating a time when each actual value or predictive value is obtained is generated and stored. The actual values and the predictive values are processed to provide an output value.

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.

A method for communicating a list of handover candidates in a wireless local area network from a station to a serving access point (AP) begins by determining a list of handover candidate APs at the station. The candidate list is sorted at the station and is sent to the serving AP. The sending step can include sending the candidate list to the serving AP upon the expiration of a predetermined period of time or upon receipt at the station of an event trigger. The method can also include the step of requesting a candidate list from the station by the serving AP.
摘要:
During a contention-free period, or silent measurement period, of a first wireless communications channel, signals received on a second wireless communications channel are analyzed. The results of the analysis are used to perform advanced radio resource management functions, such as frequency selection, load balancing, or power management. Each of a plurality of wireless channels may be measured in order to perform the advanced radio resource management functions. During the analysis, an energy detect threshold may be lowered to a minimal value.
