IX. INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to a wireless communication system, and more particularly to a method for collecting, measuring, reporting, and/or using interference control in a wireless communication system. Method and device for information. [Prior Art] In a wireless multi-directional proximity communication system, a wireless terminal competes for system resources to communicate with a common receiver on an uplink channel. An example of this is an uplink channel in a cellular radio system in which a wireless terminal is transmitted to a base station receiver. When a wireless terminal is transmitting on an uplink channel, it typically interferes with the entire system (e.g., neighboring base station receivers). Since wireless terminals are decentralized, controlling the interference caused by their transmission is a challenging problem. Many cellular wireless systems employ simple strategies to control uplink interference. For example, a CDMA voice system (eg, IS-95) power controls a wireless terminal in such a manner that its signals are received at substantially the same power at the base station receiver, such as the current state of the art, such as lxRTT and lxEV-DO. CDMA systems allow wireless terminals to transmit at different rates and receive at different bases at different base stations. However, interference is controlled in a decentralized manner, which reduces the total interference level without accurately controlling the wireless terminals that are the worst interference sources in the system. This existing body of interference control methods limits the uplink capacity of the innocent system. If the base station is available, it can be used to determine the amount of signal interference that will be generated in the adjacent cell 115454.doc 1354460 and/or sector when the transmission occurs and/or determine the amount of interference that the wireless terminal may encounter due to k-type interference. Information, it will be useful. If the information available for the decision is available from one or more wireless terminals to a base station, it will be particularly desirable. In the case of communication interference information from the wireless terminal to the base station, one type of report is better suited to the special time than the other. Methods and apparatus adapted to a variety of different interference reporting types would be beneficial. As the variety increases, control signal transmission consumes a potential option that is typically increased to support and communication is available. It would be beneficial if the method and apparatus were to keep the (IV) transmission consumption relatively low while supporting multiple interference reporting changes. SUMMARY OF THE INVENTION Various embodiments are directed to methods and apparatus for collecting, measuring, reporting, and/or using information that can be used for interference control. In each implementation <column, a 1-line terminal interface&-a broadcast uplink interference report request transmits the requested report type and/or base station identification information, eg, such as a locally unique cell identifier value The local unique base identifier. For example, in an exemplary embodiment, a base station attachment point broadcasts - a request for a plurality of wireless terminals that are used by the plurality of wireless terminals to use the base station attachment point as their current service contact. The wireless terminal also receives and measures the transmitted reference signal 'e.g., beacon and/or pilot signals transmitted from a plurality of base station attachment points. The beacon signal can be t-numbered 'amplitude' and 'single t_'. The beacon signal may have a duration of two or more symbol transmission periods (e.g., OFDM symbols, I5454.d〇c 1354460 transmission period). However, other types of beacon signals can be used and the particular type of k-labeled signal is not critical to the invention. Different types of requested reports contain specific types of interference reports (sometimes handled as special reports) and generic type interference reports. In an exemplary embodiment, if the interference report request value is a first value, for example, 〇, the request is for a generic report, and if the report request value is at a group pre-value other than the first value (eg, Within a set of positive integer values), the request is for a specific report

The selected base station attachment point to be used in a particular report has a base station identifier corresponding to the report request value. The particular type of interference report associates the currently serving connected base station attachment point with the selected base station attachment point corresponding to the received base station identifier. The k-type interference report relates to the currently serving base station connection attachment point to other unspecified base station attachment points whose broadcast reference signals have been measured by the wireless terminal debt. In some embodiments, for a generic type of interference report, the current service base station attachment point for which the report is directed is not known to be

Which special base station attachment point is used when generating the report. The subtype of the generic report contains a report that uses the summation function to generate the report and a report that uses the most: value function to generate the report. In some embodiments, timing information is sometimes used to determine the report subtype. For example, in the exemplary embodiment, the cyclic timing structure ((10) rnng timing structure is divided into the period during which the general report reports the summation function type report at the time of transmission and when the _-general report is transmitted Time σ of the maximum function type report In some embodiments, the report subtype alternates between H5454.doc ^54460: time slot (beaC_l〇t) when the cycle is scheduled. This predetermined timing structure facilitates the general reporting of the two subtypes. In some embodiments, the timing structure used to report the subtype mapping (four) is known to the wireless terminal and the current serving fan I attachment point, and thus does not require additional consumption control signal transmission type reporting subtypes' This frees valuable airborne links (4). The poor source is used for other purposes, for example, to communicate user data. In some embodiments (e.g., employing some of the at least some multi-sector cells), the (4) sequence information is used to determine the sector type for the selected attachment point for the particular type of interference report requested. For example, in an exemplary embodiment, 'using two different sector types to structure a report of a particular type of report such that the sector type of the selected base station attachment point is within a predetermined cyclic timing structure alternately. In some such embodiments, a wireless terminal determines to be used to request a particular by combining a received base station identifier from a report request with a sector type determined by the time at which the wireless terminal receives the request. The selected attachment point in the type report. As described above, in each implementation, the base station identifier communicated in the downlink broadcast report request signal is a locally unique identifier, e.g., a locally unique cell identifier. Additionally, in some embodiments, the sector identifier is communicated via the request signal timing. In various embodiments, the carrier or tone block identifier is known, eg, it is the same as the carrier or tone block identifier used by the current serving sector attachment point, and it need not be specifically in the report request Signal transmission. Therefore, the identification of the consumption control signal transmitted for the selected attachment point to be used in the request interference report is additionally required to be 115454.doc 1354460 if it transmits a system-only base station attachment point identifier in the identifier. The amount is reduced. By communicating the request with fewer bits, the valuable air link is saved (4) to other materials, for example, to transfer user data. The wireless terminal generates the requested report (eg, one of a specific report, a summation function type generic report, and a maximum function type generic report), and transmits the generated report to the current connection attachment point, _ contact (eg, Issuing a request via an uplink dedicated control channel section allocated to the wireless terminal for its own use. Although various embodiments have been discussed in the above [Disclosed Summary], it should be understood that not necessarily all embodiments include the same features, and Some of the features described above are not necessary but may be desirable in some embodiments.

In an exemplary system, the traffic segments that make up the uplink traffic channel can be defined in different frequencies and time ranges to accommodate a wide range of wireless terminals operating on a different set of wireless channels and under different device constraints. machine. Figure 6 is a graph 100A of the time on the vertical axis 102 eight versus the horizontal axis 1 〇 4 八. Figure 6 illustrates two traffic segments in the uplink traffic channel. The frequency range occupied by the traffic section indicated as A 1 06A is expressed as twice the frequency range occupied by the traffic section of B 108A. The traffic segments in the uplink traffic channel can be dynamically shared between the wireless terminals communicating with the base station. The privilege module (which is part of the base station) can quickly assign traffic channel segments to different users based on user traffic requirements, device constraints, and channel conditions that typically change over time. Therefore, the uplink traffic channel is effectively shared and dynamically allocated between different users on a segment-by-segment basis. The dynamic allocation of the traffic segments is illustrated in Figure 6 where segment A is assigned to user #丨 by the base station scheduler and segment B is assigned to user #2. H5454.doc -21 - 1354460 In an exemplary system, the assignment information of a traffic channel segment is transmitted in an assigned channel. The assigned channel contains a series of assigned segments. Each traffic segment is associated with a corresponding unique assigned segment, the assigned segment transmitting an assignment identifier that can include an identifier of the wireless terminal and a coding and modulation mechanism to be used in the traffic segment . Figure 7 is a graph 200A of the time on the vertical axis 202A versus the time on the horizontal axis 204A. Figure 7 shows two assignment sections Α 206 Α and Β ' 208 Α which respectively transmit assignment information for uplink traffic segments a 210 Α and ^ B 2 12 A. Assign channels to share channel resources. The wireless terminal receives the assignment information transmitted in the assigned channel and then transmits on the uplink traffic channel segment based on the assignment information. The base station scheduler 230 allocates traffic segments based on a number of considerations. A limitation condition is that the transmission power requirement of the traffic channel should not exceed the transmission power capacity of the wireless terminal. Thus, a wireless terminal that operates on a weaker uplink channel can be assigned a traffic segment that occupies a narrower frequency range in the exemplary system so that the instantaneous power requirements are not severely limited. Similarly, it is also possible to allocate a traffic section containing a smaller frequency range for a wireless terminal that generates a larger amount of interference in order to reduce the influence of transient interference generated by the wireless terminal. The total interference is controlled by the transmission schedule of the wireless terminal based on the interference cost of the wireless terminal to the system, and the interference costs are hereinafter emphasized. The wireless terminal determines the interference cost to the system from the received downlink key broadcast signal. In an embodiment, the wireless terminal reports its interference to the base station as a interference cost in the form of an interference report: which then causes the uplink schedule to control the uplink interference. In the case of another police force, the base station broadcasts a 115454.doc-22. disturbance control indicator, and the wireless terminal uses its interference cost and the received indication = in a proper manner (for example, has a lower An action body indicating that the uplink transmission cost is not allowed by the control may be transmitted, and an action body having an interference cost exceeding a cost level indicated by the control indicator will suppress transmission) determining its uplink Transfer resources. Exemplary interference costs that may be considered will now be described. Consider - marked as a W wireless terminal. Assume that the wireless terminal is connected

To the base station.

In an exemplary system, a wireless terminal w. The amount of power transmitted on the uplink traffic segment is typically from the wireless terminal w. The status of the wireless channel to the base station, the frequency range, and the choice of the code rate on the traffic segment. The frequency range of the segment and the choice of the code rate determine the transmission power used by the mobile unit, which directly causes the amount of interference. It is assumed that the SNR required by the base station receiver to solve the code segment requires the traffic segment. The received power pR per tone (which is a function of the choice of bit rate and channel conditions, the mobile terminal operates in the 4-channel case). This relates to the transmission power Ρτ of each tone of the wireless terminal, as follows: PR = PTG0,0 The interference per tone generated by the wireless terminal at the adjacent base station k can then be calculated as follows: G0k

The interference generated at the base station (4) is proportional to its transmission power and channel gain and the ratio of the base station k and its own base station. Therefore ~ is called wireless terminal w. The cost of interference to the base station. > To summarize this concept, the total interference generated by the wireless terminal for each tone of all neighboring base stations is:

It will be described in some embodiments to determine the interference cost. In an exemplary embodiment, each base station 1 〇 2, ι 4 of the exemplary system 1 以 includes a periodic reference signal reference 彳 5 可 detectable and decodable by the wireless broadcast terminal. Beacons, pilots, or other common control signals. The reference h may have a unique type to identify the cells and sectors of the base station. In an exemplary OFDM system, a beacon or pilot signal may be used. Reference signal. The beacon signal is a special 〇FDM symbol, in which most of the transmission power is concentrated on a small number of tones. The frequency position of these high-power tones indicates the identifier of the base station. The pilot signal can have a special hopping pattern. ), which also uniquely specifies the identifier of the base station 1〇2 Thus, at 115454.doc -24· 1354460 and/or the pilot signal identifying the base station fan in the CDMA system, the pilot signal can be used as a reference signal. For example, in the system f 'the pilot system has a specific time offset a known spread spectrum sequence as a weaver of the base station. σ Although the above-mentioned heart (4) system (10) ❹ beacon or pilot number provides a reference signal for path loss estimation, the present invention is applicable to the use of straight-through Technology to provide a wide range of systems for reference signals.

The reference signal is transmitted at a known power. Different References Can Be Transmitted for Different Powers Different base stations 102, 114 can use different power levels for the same type of > test number as long as such power is known to the mobile terminal. The wireless terminal 106 first receives the reference signal to obtain the identifier of the base station 102. Subsequently, the wireless terminal (10) measures the received power of the reference signal, and # is calculated from the channel gain of the base station 1〇2 to the wireless terminal unit 1〇6. Note that at a given location, the wireless terminal may be able to receive reference signals from multiple base stations 102,114. On the other hand, the wireless terminal may not be able to receive reference signals from all base stations in the entire system. In the exemplary system, the wireless terminal unit monitors the % of the base station to which it is connected, 〇, and the base σ * G 〇, k (if it can receive the corresponding reference signal, therefore, the wireless terminal station. The group base station maintains an array of interference costs {^}, and the wireless terminal unit % can receive the reference signals of the group of base stations. Note that the wireless terminal unit 106 can derive the interference cost by combining the estimates from the plurality of reference signals. For example, in an exemplary 〇fdm system, the wireless terminal unit 〇6 can use the beacon and the pilot to derive (the estimate of the ro d 0 115454.doc 25- 1354460 interference cost {ra,k} will be Used to control uplink interference and increase total system capacity. The uplink traffic channel can be used in two modes: The following describes the use of interference cost in two modes. It should be noted that the wireless terminal 106, 108 measures The channel gain from the downlink reference signal is m, and the + disturbance is a measure of the cost of the interference in the impact on the uplink. The downlink between the wireless terminal 1〇6 and the base station ι〇2 Link and uplink Zo benefits

The effect of removing short-term changes can be (and in 4 implementations === the estimated value of the channel gain of the downlink reference signal is averaged (eg in the form of low-pass filtering) to obtain an estimate of the interference cost {rGk} The value of the determined interference cost is now discussed in the scheduling mode of operation. In a particular mode of operation, each of the uplink traffic segments is explicitly assigned by the base station to enable an uplink. The traffic segment is only used by at most one wireless terminal. In the exemplary OFDM system, since the traffic segments are orthogonal to each other, there is usually no such presence in the uplink traffic segment in this mode.

Interference in the small area. To facilitate scheduling at the base station 102, in accordance with the present invention, each of the wireless terminals 1G6, 1G8 transmits an Interference Report to the base station 102 that is connected to the wireless terminal. In some embodiments, the reports indicate the calculated interference cost {rG,k}. In extreme cases, the report contains control messages for the entire array of interference costs {r〇,k}. However, to reduce signal transmission overhead, only one quantized version of the array {r〇k) is transmitted in one embodiment. As listed below, there are several ways to quantify κ {γμ}. • Report all {r〇,k} and r(), tc)tai. 115454.doc -26 - 1354460 The maximum value of {rG,k} and the exponential associated with this maximum. • Periodically report {ra,k} and associated indices!^ using the level to report r〇,k. For example, two levels are used to indicate whether rQ k is strong or weak. After receiving the interference report, the base station schedules the traffic segment as a function of the interference information (for example, assigning a scheduling policy to limit the total interference generated by all scheduled wireless terminals to one) The threshold is predetermined. Another • The scheduling strategy classifies the wireless terminals into groups according to the reported {rG k} of the wireless terminal, so that it is better to assign L έ smaller frequencies to groups with large interference costs. Range of traffic segments to reduce the effects of transient interference generated. Consider an embodiment in which each base station 1 知道 2 knows its neighboring group, that is, it is determined to be a neighbor from the point of view of interference. A group of base stations U4, etc. In a basic embodiment, base station 1〇2 only attempts to control the total interference to neighboring base stations. The basic embodiment can be used for adjacent φ base stations in almost all interferences (cellsΧ In the sense that one of the special persons can be roughly, for example, since all scheduled wireless terminals can be close to the cell X. In this case, the cell X experiences severe interference at this time instant. At another time instant, Interference can be set On a different adjacent base station, in this case 'cell X experiences a little interference. Therefore, in the above embodiment of the total interference control, the interference to a particular neighboring base station may have a large change. To avoid inter-cell interference instability, the base station 1 2 may have to leave sufficient margin in the total interference generated to compensate for this large variation. In an enhanced embodiment, the base station 102 is in a common control channel. The broadcast 115454.doc • 27· 1354460 a message to direct the wireless terminal 106, 108 to determine and report the interference cost for a particular base station A. Therefore, the wireless terminal ^(j=〇, 〗, 2, ...) Sending a report of r, k. After a period of time, the base station 1〇2 repeats the process for each of its neighboring groups and determines the group of wireless terminals 106, 108 that interfere with each of the base stations. Once this classification is completed, the base station 102 can simultaneously allocate the uplink traffic section to one of the groups of wireless terminals 1, 6 and 108 that interfere with different base stations, thereby reducing the number of base stations for any special base station. The disturbance of the station. Advantageously, since the interference has less variation, the base station 102 can allow for greater total interference without severely affecting system stability, thereby increasing system capacity. The wireless terminals 106, 108 within the cell 1〇4 are caused to Neighboring base station 114 can ignore interference and can therefore be scheduled at any time. The use of interference cost in some, but not necessarily all, non-scheduled modes of operation will now be discussed. Each of the uplink traffic segments is not explicitly assigned by the φ base station 102. As a result, an uplink traffic segment can be used by multiple wireless terminals 106, 108. In CDMA systems, due to uplinks The link traffic segments are not orthogonal to each other, so intra-cell interference typically occurs in the uplink traffic segment in this mode. In this mode, 'each wireless terminal 1, 、6, 〇8 makes its own scheduling decision as to whether it wants to use the uplink traffic segment and, if so, which data rate and power to use. To help reduce excessive interference and maintain system stability, according to various embodiments, the base station broadcasts an interference control indicator. Each wireless terminal 106, 108 compares the reference level with its interference cost and determines its scheduling decision. In an embodiment, the interference control indicator can be a multi-level variable, and each level indication The base station 102 wants to control the total interference more strictly. For example. The delta broadcasts the lowest level, allowing each of the wireless terminals 106, 108 to use each of the traffic channel segments at each of the rates. When the broadcast is at the highest level, then the wireless terminal 106, 108, which only interferes with the extremely low cost, can use the traffic channel segment. When the broadcast is in the middle level, the wireless terminal devices 106, 1 8 having lower interference costs can use all the traffic channel segments, preferably the traffic segments including the larger frequency range, and the wireless devices with higher interference costs. The terminal sets 106, 108 can only use traffic segments that are comprised of smaller frequency ranges and are at a lower data rate. The base station 102 can dynamically change the interference control level of the broadcast to control the amount of interference generated by the wireless terminals 丨〇6, 1 〇8 of the cell 1 对4 to other base stations.

Operation proceeds from step HH8 via the connection node A 1 〇 42 to the step purchase, wherein the wireless terminal generates one or more interference reports. Return to the step surface where the wireless terminal is operated to receive broadcast load factor information. Therefore, in the exemplary embodiment, the wireless terminal transmits the coverage factor of the current serving base station sector from the current service base, the sector transmission, and the transmission of the current service base station sector. The terminal device can be from the current or interfering service base station sector. The load factor information of the sector of the service base station transmitted by the transmitter. Although the number is shown to be received from the current serving base station sector, the load factor information may be received from other nodes and/or pre-stored in the wireless terminal. For each base station sector under consideration, the operation proceeds to step deletion. In the step of deleting, the wireless terminal decides; t whether the load factor is successfully recovered from the received signal. If the load factor is successfully recovered from the received signal, then operation proceeds to step 1030' where the wireless terminal stores the load factor.

The beacon ratio report provides information from the

A function that receives base station sectors and receives measured downlink broadcast signals (e.g., beacon signals and/or pilot signals) from one or more other interfering base station sectors. In terms of quality, the beacon ratio report can be used to estimate the relative proximity of the capital to other base station sectors. The beacon ratio report can be used (and indeed in the second embodiment) to control the uplink link rate of the WT at the serving B8 sector to prevent excessive interference to other sectors. In some embodiments, the 'beacon (iv) report is based on two factors (1) estimated channel gain ratio, expressed as 仏, and (丨丨) load factor, expressed as h.

• In some embodiments, the channel gain ratio is defined as follows. In the currently connected tone block, in some embodiments, the WT determines the estimated value of the ratio of the uplink channel gain to the channel gain of the self-funded to the service from any of the interference base station fans (4) (4) i). The & ratio is expressed as G·. In general, the uplink channel gain ratio is not directly measurable at the expense. However, since the uplink and downlink link path gains are generally symmetrical, the ratio can be estimated by comparing the relative received power of the downlink signals from the serving BSS and the interfering BSS. The reference downlink signal—possibly selected as the downlink beacon signal—is very suitable for this purpose because it can be detected at very low (four). In some embodiments, the beacon signal ratio is 115454.doc • 36· 1354460 from other downlink transmission power levels of the base station sector. In addition, the beacon signal: every tone of the sign = = order = for (four) and measuring the beacon signal is not necessary. For example, the 1) real & financial signal is a high-power f-frequency (for example, single-tone), and two signals with a wide transmission period of 0. Therefore, at a certain location, the WT can detect and measure the price of the other downlink broadcast signals (e.g., pilot signals) from the base signal of the G.

- Measurement may not be feasible. Using the beacon signal, the uplink path ratio can be given by GMBi/PBo, where pB〇 is the measured received beacon power from the interference and serving base station sectors, respectively. Since the beacons are usually transmitted quite infrequently, especially in a decaying environment where the power is rapidly changing, the power measurement of the beacon signal may not provide an accurate estimate of the average channel. For example, in some implementations In the example, a beacon signal is transmitted for each beacon time slot of the 912 OFDM symbol transmission period, the beacon signal occupies the duration of two consecutive 〇FDM symbol transmission periods and corresponds to the downlink of the base station sector. Tone block. On the other hand 'often the pilot signal is transmitted much more frequently than the beacon signal, for example, in some embodiments, the pilot signal is transmitted during 896 periods of 912. OFDM symbol transmission periods of a beacon slot . If the WT can detect the pilot signal from the BS sector, it can self-measure the received pilot signal instead of using the beacon signal measurement to estimate the received beacon signal strength. For example, if the WT can Measure the received pilot power pPi of the interfering BS sector, which can estimate the received beacon power PBi from the estimated PB^KZiPPi, where κ is the nominal ratio of the beacon to the pilot power of the interfering sector (nominal 115454.doc •37- 1354460 ” is the same for each of the BS sectors, and Zi is the sector-dependent nose-changing factor. Similarly, if the pilot signal power from the serving BS is measured at the WT, J is The received beacon power ΡΒ〇 can be estimated from the relationship (estimated ° 〇?〇), where Ζ〇 and ΡΡ〇 are the scaling factor and the measured received pilot power from the serving base station sector, respectively.

2 observation; & the received pilot signal strength corresponds to the serving base station sector: the measured, and the received beacon signal strength corresponds to the interference base station sector can be measured, then the beacon ratio can be from (the following formula) estimate:

Gi=PBi/(PP〇 κ Z〇 ). It has been observed that if the pilot strength can be measured in both the serving sector and the interfering sector, then the beacon ratio can be estimated from (the following):

Gi^PPi K Zi/(PP〇 κ Z〇 )=PPi Zi/(PP〇 z〇 } 0

The scaling factors k, ZjZp can be system constants or can be inferred from wt from other information from bs. In some embodiments, some of the scaling factors (K, Zi' Z.) are system constants and the scaling factors (K, zi, z.) are inferred by the WT from other information from the BS. In some multi-carrier systems & ten's conversion factors & and 2 with different power levels on different carriers. A function of a downlink tone block. By way of example, an exemplary BSS has three power layer levels, and the three: power rate re-levels are associated with each downlink tone block corresponding to a BSS attachment point. In some of these embodiments, three power level levels are: - different ones are associated with each of the different pitch blocks of the BSS. Continuing:: For example, for the BSS of t; the per-power level is associated with H5454.doc -38-2, for example, one of bssP〇werN〇minaI0, and /SP〇WerN〇minaI2, and The pilot channel signal is transmitted in a relative power level for the nominal bss power level of the tone block (eg, higher than the nominal bss power level yoke transmission being used by the tone block, however, regardless of the beacon From which-tone block transmission, for the relative transmission power level of the beacon per tone of (4), the same, for example, higher than the power level block used by the power layer block (bssPowerNominal〇) 23·8 dB.

Thus, in this example, for a given Bss, the beacon transmission power will be (four)' in each of the tone blocks and the pilot transmission power is different, for example, the pilot transmission power of different tone blocks corresponds to different powers. Level level. The set conversion factor for this example would be k = 23.8_72 dB, which is the ratio of beacon power to pilot power for layer 0, and Zi is set to the layer of the interfering sector and the layer of the sector. The relative nominal power of the power.

In some embodiments, parameter 2 is determined from stored information (e.g., table 900 of FIG. 9) based on how the current connected bar is used in the serving BSS (as determined by the bssSectorType of the serving BSS): (^ for example If the currently connected tone block is used as a layered tone block by the serving BSS, then Z〇=l; if the currently connected tone block is used by the serving BSS as the layer 1 tone block, then

Z0=bssP〇werBackoff〇l ; If the currently connected tone block is used by the serving BSS as a layer 2 tone block, then Z〇=bssPowerBackoff02.

In the example of FIG. 14, the wireless terminal set 80 1 〇 has a wireless connection 807 with the BSS 8016 using the tone block i physical attachment point (^About the beacon ratio report for communication on the connection 8〇7〇, BSS 8016 In order to serve the BSS, it is sometimes expressed as BSS. In this example, 'from the perspective of WT 8010, bSS 8012, 8〇26, 8〇36, 8008 do not interfere with the base station sector, sometimes expressed as a wireless terminal.

The phonetic, wt丄8010 is compared with the BSS 8016 tone block 1 attachment point timing. The pilot channel is synchronized, and thus the pilot channel can be accurately measured. The wireless terminal receives and processes the beacon signals (8072, 8〇82) communicated in the tone block! from each of the interfering BSSs (8012, 8026, 8036, 8008). , 8〇86, 8〇9〇, for example, using early tones, compared to other downlink broadcast signals (such as pilot signals), transmitted at a relatively high transmission power level per tone and having two consecutive OFDM symbols Beacon signal for the duration of the transmission period than the pilot The number can be more easily detected (for example, over a longer range) and does not require accurate measurement of accurate timing synchronization. In addition, each from BSS (8〇16, 8〇12, _, 8036, 8008) The uplink communication load factor information signals (8080, 8074, 8084, 8088, 8〇92) are communicated. These uplink key load factor information signals _〇, 8074, 8084, circle, 8〇92) are used as broadcast signals. Communication, but may or may not be successfully recovered, for example, because its transmission power level per tone is lower than the transmission power level per beacon of the beacon. In the case where the uplink load factor cannot be successfully recovered, the beacon ratio A preset value (eg, value 丨) is used in the report calculation. The generation of an exemplary universal beacon ratio report will now be described, the resulting generic beacon ratio report being communicated over the connection 8经由7〇 via the dedicated control channel segment. The service BSS (BSS〇) is the BSS 8016. The PP() is the wireless terminal that receives the pilot signal 8076.

The uplink load factor (b〇, bl, b2, b3, Μ) (if successfully recovered) is recovered from the signals (8080, 8074, 8084, 8088, 8092), respectively. The value of each b is greater than or equal to zero and less than or equal to 丨. If the given b is not recoverable, the default value of 1 is used. Since the tone block 81〇2 is used for pilot and user data signal transmission, the indicator function = 1. Since tone block 1 is used by BSS 8026 for pilot and user data signal transmission, it means that the function 12 = 1. Since the tone block i is not used by the Bss 8036 for pilot and user data transmission, the indicator function l3 = 〇. Since tone block 1 is used by BSS 8008 for pilot and user data signal transmission, it means that the function 14 = 1. κ is the ratio of the transmission power of the beacon channel for the layer 0 tone block to the per tone of the pilot channel, which is a constant of the system. Since Bss 8016 sound δ week block 1 is a layer 2 tone block, z〇=bssPowerbackoff02 β because BSS 8012 a δ week block 1 is a layer 1 tone block, so z1=:bssP〇werbackoffO 1 . Since the tone block 1 of the BSS 8026 is a layered tone block, Z2=1. Because 13 = 〇 ', the Z3 system is irrelevant. Since the tone block 1 of the BSS 8008 is a layer 1 曰 block, so Z4 = bssPowerbackoff01.

Operation proceeds from step 5536 to step 5568, in which the wireless terminal is operated to transmit the report to the first current serving base station sector that serves as the current attachment point for the wireless terminal. In some embodiments, the reported transmission is in response to a request from a serving base station sector. In some embodiments, the type of transmission (e.g., 'specific or generic) is in response to the received signal transmission from the base station sector identifying the type of the report. In some embodiments, the transmission of a special feature type report that reports interference associated with the particular base station sector is responsive to - identifying the received base station signal for the particular base station sector. In various embodiments, the interference report is transmitted periodically based on the reporting schedule followed by the wireless terminal (e.g., as part of a dedicated control channel structure). In some of these embodiments, the base station does not signal any report selection information used to select the report for at least some of the interference reports transmitted. In some implementations, the base station acts as a __ function of the #pre-position in the cyclic timing structure to report on the two types of universal beacon ratios (eg, using information about each of the received interfering BSSs). The calculation between the sum-type 'and-based based on the second type of information from the single-worst interfering BSS'. For example, when the beacon index in the slot is even, the general U ratio report of the first type is calculated and the slot index in the timeout slot calculates the second type of universal beacon ratio report. . In some embodiments, only the generic beacon ratio report is sent by default, and the specific beacon ratio report is sent only when the base station requests the report. In some embodiments, the system includes a plurality of, e.g., three levels having a level with each layer: transport layer level (for example, the power conversion si number. For example, the difference between the + and the I target)

In some embodiments, each attachment point corresponds to a - base station sector transmitter and a tone block, and each _ attachment point coffee transmitter tone block can be associated with a - power transmission layer level. In some embodiments, there are a plurality of downlink tone blocks, for example, three i-modulation blocks (tone block 音, pitch block vowel block 2), and each-tone block has 113 consecutive evenly spaced tones. In some embodiments, the homo-tone block (e.g., tone block 0) used by different base station sector transmitters has different power transmission layer levels associated with the non-base station transmitter. Wireless terminal 2 (eg, 'using information transmitted via its beacon signal, using a loop

In some embodiments, the parameter κ is a value greater than or equal to 6 dB. For example, in an exemplary embodiment, the parameter K = 23_8 dB - 7.2 dB = 16.0 dB. Figure 18 is a diagram 1800 of exemplary timing structure information and corresponding interference reporting information (e.g., beacon ratio report reporting information) for an exemplary embodiment. The exemplary timing structure includes an uplink timeout slot as indicated by column 18〇2, and the Suichuan 02 display index = 上行 uplink overclocking followed by an uplink timeout slot of index -1. In the exemplary embodiment, each timeout slot contains 18 indexed beacon slots as indicated by column 1804. Each beacon slot contains, for example, 912 consecutive OFDM symbol transmission periods. In this exemplary embodiment, the 'wireless terminal' can report two different types of beacon ratio reports, for example, via a dedicated control channel segment to a serving base station sector, a first type of letter # rate reporting system. The generic beacon ratio report and the second type t beacon ratio report are specific beacon ratio reports (sometimes referred to as special letter 1 rate reports). The first-type beacon ratio report is a generic beacon ratio report and uses two subtypes of generic beacon ratio reports. First-subtype: The generic "ratio report determines the reported value as a function of one or more interfering base station sectors. The general subtotal ratio report for the second subtype is determined to be the maximum value (eg 'in terms of interference value') The reported value of the function of the worst-case sector. As indicated by the column deletion, to be used = 115454.doc -62- 函数 The sub-type of the beacon ratio report, the function of the beacon time slot index.

For the beacon The odd value of the time slot index (Bu 3, 5, 9, 9, 15, 15) 'The wireless terminal uses the maximum function to determine the report β column 18〇8 indication when transmitting the general beacon ratio report. When the terminal transmits a specific beacon ratio report, the communication-corresponding to the report of the base station sector, the sector is identified in a request and has a sector that is a function of the value of the slot 4 曰Type. For example, consider using two different sector types (sector type〇 Sector type 丨, and sector type 2). A request signal from a serving base station sector requesting a specific type of beacon ratio report may include a cell identifier value (eg, a slope value) and communicate therein The report's uplink timing structure determines the sector type. For example, for the index = (〇, 3, 6, 9, 12, 15) beacon time slot 'wireless terminal is reporting a specific beacon ratio report When reporting a specific beacon ratio report that associates the serving base station sector with another base station sector identified by a communication cell identifier value and having sector type = 0. For index = (1, 4) , 7, 10, 13, 16) beacon time slot, when the wireless terminal reports a specific beacon ratio report, 'reports one to make the serving base station sector and is identified by a communication cell identifier value and has a sector type =1 other - specific beacon ratio report associated with the base station sector. For beacon time slots of index = (2, 5, 8, 11, 14, 17), the wireless terminal reports a specific beacon ratio report When reporting a service base station sector with a small communication The specific beacon ratio report β w w identified by the identifier value and having another sector of the sector type = 115454.doc -63· 1354460 observes that this is understood by both the base station and the wireless terminal. Based on the report format of the predetermined timing structure, the line supports multiple report formats while limiting the amount of transmission of the k-number. In addition, it should be observed that for a particular message 'ratio report' is partly by the information contained in a request signal and Obtaining the base of interest by the position in the uplink timing structure

The identification of the σ-Yu area, which requires the use of the e-number transmission wheel requires fewer bits to identify the base station sector of interest. Figure 19 illustrates, in the context of Figure 19, an exemplary beacon ratio report D? for downlink nickname transmission and exemplary uplink beacon ratio report signal transmission. In diagram 1900, base station sector 1902 (for the current attachment point of wireless terminal 1904) transmits a downlink traffic channel control signal, for example, as part of the downlink signal control channel flash signal. 1906, which contains information on the beacon ratio report request field 19咐. In the Long implementation, the signal containing the request field for the beacon report is broadcast ##, for example, intended to be used by the guest & Therefore, one control (4) is broadcasted for the plurality of connected wireless terminals to use the level of the consumption control signal that will be additionally required when individually controlling each of the pay line end machines with respect to the type of interference report to be transmitted. . In one such embodiment, the request for the 'single-to-beacon ratio report is reported to report multiple uplink channel interferences to be communicated by the wireless terminal. In some embodiments, a single pair of beacon ratios is reported. : In-single-to-beacon-to-beacon (s).

If the value is a non-zero positive integer, then the wireless terminal will report the -standard ratio report 'and the value corresponds to a cell identification by the base station sector of interest", for example, the slope value. In some embodiments: The slope value is a value corresponding to the slope of the pilot tone signal. However, in the embodiment, the plurality of base station sectors in the same cell use the same, the slope value and thus the uplink timing information is also used. Mosquitoes are used for special base station sectors of interest for special specific beacon ratio reports (eg, timing assets indicated by the deletion).

In some other embodiments, the wireless terminal pre-transmits the first type of report' and transmits a type: report when the request signal for the beacon ratio report is communicated. For example, 'a generic beacon ratio report can be communicated by default'. If the base station wants to communicate a specific type of beacon ratio report, the base station k contains a request-specific control channel for the beacon ratio report of the cell identifier information. The segment signal 1910 includes a beacon ratio report 191 based on the request information and uplink timing structure information. The segment signal 1914 includes a beacon ratio report 1916 based on the request information and the uplink timing structure information. For example, consider requesting location 1908 to transmit a value of 115454.doc -65 - 1354460. The report 19 12 corresponds to a beacon ratio report for communication during the slot of the index = 信, and the report 1916 corresponds to the beacon ratio report for communication during the slot of the index = ι. The beacon ratio report 1912 is a general beacon ratio report that uses a summation function to calculate a report value that correlates the detected base station sector of the same tone»week block with the serving base station sector; beacon ratio Report 1916 is a generic beacon ratio report that uses a maximum function to calculate a reported value. This report associates the detected base station sector φ of the same tone block with the serving base station sector. Considering that the request block 1908 transmits a value of 1, the report 1912 corresponds to a beacon ratio report for communication during the time slot of the index = 信, and the report 1916 corresponds to a beacon during the time slot of the index = 1 Beacon Ratio Report "Beacon Ratio Report 1912 is a specific beacon ratio report that associates the current serving base station sector attachment point with a local base station sector."
