BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to wireless communication systems for communicating, for interference control purposes, and/or for use in wireless communication systems. And, more particularly, a method and apparatus for collecting, measuring, reporting, and/or using load management information. [Prior Art] In a wireless multi-directional access communication system, a wireless terminal _ contends system resources so that Communicate with (4) pure ^ on the - uplink channel. An example of this situation is the cellular (m) uplink channel, which is transmitted to the base station to receive the II m terminal when transmitting on the uplink channel, which usually causes the entire system (eg, adjacent base stations) Interference from the receiver) Because the wireless terminal is dispersed, controlling the interference caused by its transmission is a challenging problem. Many cellular wireless systems take simple strategies to control uplink interference as an example. The CDMA voice system (e.g., is_95) power control wireless, -; in this manner, the signal is received at substantially the same power at the base station receiver. Modern cdma systems such as lxRTT& lxEV D〇 allow wireless terminals to transmit at different rates, and can receive different functions at the base station. However, the interference is controlled in a decentralized manner, which reduces the overall interference rather than accurately. Controlling the wireless terminals that are the worst sources of interference in the system, and seeing that the interference control method may be applicable, but the interference continues to limit the uplink capabilities of the wireless system, and new and/or improved interference control methods 115458.doc 1380726 is applicable. β H provides information that can be used to determine the amount of signal interference that will be generated in adjacent small or sector when transmission occurs and/or to determine the amount of interference that the wireless terminal may suffer due to the signal: the interference would be of. It would be particularly desirable if information available for interference determination purposes could be supplied by one or more wireless devices to a base station'.

The load affects interference considerations in wireless communication systems. ^ In some embodiments (but not all real (4)), the message can be used for wireless terminals and/or bases. 'This would be beneficial if the wireless terminal and/or the base station use the load information to determine This would also be beneficial in terms of the degree of interference. Therefore, there is a need for novel methods and/or apparatus for communicating and/or using load disturbance information for interference control purposes.

Before the g is connected to the base station connection point and the wireless terminal can readablely receive the detailed feature information broadcasted from the base station with which it has the current connection; however, the wireless terminal is restored from other base stations (eg Information near the base station can be difficult. If the wireless terminal can expect to recover the load information about the nearby base station, the information can be used in a well controlled interference report. This would be beneficial if the method and apparatus facilitated the reliable transfer of load information from a plurality of base stations in the vicinity of the wireless terminal to the wireless terminal. Some communication systems may use a centralized control method (e. g., using a core node) to manage interference and/or load balancing; however, the method is subject to signal transmission and processing delays and may limit the amount of traffic that can reasonably be communicated to the core node. Therefore, the core node approach used in some systems can tend to 115458.doc 1380726 Slow i cannot quickly adapt to changes that result in efficient allocation of resources. In view of the above discussion, it should be appreciated that there is a need for improved and/or novel and improved interference management techniques for communications that can be used to control interference. SUMMARY OF THE INVENTION Various embodiments are directed to methods and apparatus for communicating, collecting, measuring, reporting, and/or using information that can be used for interference control purposes and/or load management. The method and I are described, #_ receiving load information about the load status of neighboring base stations at the base station, and then being used and/or communicated to the mobile node in the cell in which the receiving base station is located. Thus, the base station can communicate information about the load of a particular base station and the load of neighboring base stations (e.g., physically adjacent base stations). If the mobile node can reliably receive load factor information not only corresponding to the base station to which it is connected but also can reliably receive load factor information from other base stations in its vicinity in the communication system, causing interference reports and/or making This is beneficial when considering the burden in a variety of decisions. Therefore, information about neighboring base station loads can be used to improve interference control. For example, in various embodiments, a mobile node generates an uplink based on known signals (eg, beacon and/or pilot channel signals) received from its own base station and from other base stations (eg, neighboring base stations). Link interference reports, such as beacon ratio reports. In some embodiments, the interference report also utilizes the base station load information y when available to calculate a more accurate report. A more strictly controlled interference report is generated by the improved wireless terminal being able to successfully recover and use neighboring base station load information to generate interference reports. Therefore, interference and/or load management by the base station receiving such reports may be more effective.

According to various embodiments, the base station communicates its load factor information to a neighboring base station, for example, via a backhaul network. The base station receives the transmitted load information from the neighboring base stations and broadcasts its own load factors and load factors corresponding to the adjacent base stations. Therefore, the load factor information from a plurality of base stations in the vicinity of the communication system can be easily used for the action node, thereby facilitating the improvement of the dry control. This overcomes the difficulty of the mobile node receiving the load information directly from a base station different from the base station having the communication link. It should be understood that the mobile node in the wireless communication system can be currently connected to the first base station and synchronized with respect to the first base station. The mobile node can typically reliably receive broadcast information from the particular base station. However, the mobile node may or may not be able to reliably recover broadcast information from neighboring base stations. For example, a wireless terminal can detect and measure a high power beacon signal, but it cannot recover other control information broadcast signals from neighboring base stations. By having the base station transmit information about the load of the adjacent base station, according to various embodiments, the problem that the mobile must receive the information directly from the adjacent base station on the radio is resolved.

For example, as shown in the figure, the current connection to Bs 5 1〇5 [: can be relative to other neighboring base stations (such as base station 2iQ2 and base)

J=T. In the example of Figure 3, each base station transmits a packet with a hash number and a pilot channel for the broadcast broadcast of the link load factor signal. (4) The characteristics of the signal contribute to easy detection, even by the wireless terminal that can accurately determine the gate condition and/or the transmission beacon 2 with respect to the base station transmitting the beacon signal. For example, the signal is relatively high power, in which: two = a few tones, and the width of the beacon signal is greater than the typical (four) call number signal, for example, the beacon two 115458.doc 1380726 symbol wide with ~ initial symbol portion and an extended portion. In this embodiment, the pilot signal is transmitted at a lower power per tone than the beacon signal, transmitted more frequently than the beacon signal and follows the predetermined Tone skip mode. The uplink load factor broadcast signal is transmitted as part of the broadcast information signal. A single broadcast signal conveying the load factor information can convey one or more uplink load factors. Time-synchronized wireless terminals with good channel conditions (such as wireless terminals that are currently connected to the base station φ connection point and experience good channel conditions) should be able to Restoring the uplink load factor broadcast signal.

It should be understood that if the wireless terminal does not ride the proximity base station load factor information, then the wireless terminal may have to make a calculation - reporting a predetermined value of the unrecovered neighbor base station load factor. In this case, the surplus line can eventually be conservatively preset using one of the unrecovered load factors of the neighboring base stations that cause the interference level to be overestimated. When the base station considers the interference report and allocates resources, this will have a tendency to waste radio link resources. Thus, by communicating the proximity base station load factor via the current connection, the likelihood that the wireless terminal will be able to successfully recover the load factor of the adjacent base station is significantly improved. This can result in more accurate and better controlled interference reporting. By providing more consistent and accurate interference reports to the base station, the base station can allocate resources more efficiently and manage interference. 11 is a diagram of a flowchart 1100 of an exemplary method of operating a first base station in a multi-directional access wireless communication system including a plurality of base stations.
