Description

200816669 IX. INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present disclosure relates generally to communications and, more particularly, to utilizing by a User Equipment (UE) in a wireless communication network. The technology of measurement. [Prior Art] Wireless communication networks are widely deployed to provide various communication servos such as voice, video, packet data, messaging, broadcast, and the like. These wireless networks can be multiple access networks that can support multiple users by sharing available network resources. Examples of such multiple access networks include code division multiple access (CDMA) networks, time division multiple access (TDMA) networks, frequency division multiple access (FDMA) networks, and orthogonal FDMA (OFDMA) networks. Road, and single carrier fdMA (SC-FDMA) network. A wireless network may include a number of hives that support communication for many users. Each hive can be associated with radio frequency (RF) parameters such as antenna downtilt, antenna orientation, antenna pattern, pilot power, noise floor, and the like. The RF parameters of each hive can be set to achieve the desired coverage and capacity for the hive. During a hive planning phase, the traffic map and the ruler propagation model can be applied to a honeycomb project that can determine the RF# number of the hive to achieve the desired performance. In many instances, the Rule 1 parameter can be determined by suboptimal history due to inaccurate and/or insufficient input of the Honeycomb Tool. This can result in sub-optimal network performance, such as more disconnects, more call setup failures, lower throughput, and the like. SUMMARY OF THE INVENTION 123353.doc 200816669 Techniques for improving network performance using measurements made by a UE are described herein. In one aspect, the RF parameters of the hive can be determined by considering the mobility of the UE. The mobility information for the UE can be determined based on the measurement report information (MRM) for handover delivered by the UE. The RF parameters of the hive such as antenna downtilt, antenna position, antenna pattern, pilot power, and/or noise floor can be determined based on the UE's mobility information. These RF parameters may also be further determined based on RF measurements from UEs, traffic maps, RF propagation models, and the like. In another aspect, the RF parameters of the hive can be dynamically adjusted based on the loading conditions. The loading conditions of the hive can be determined based on the MRM of the UE and/or via other components. The RF parameters of the hive can be adjusted based on these loading conditions to improve network performance. In another aspect, the location of the UE can be determined based on a MRM sent by a UE for handover. The MRM can include timing measurements for multiple cells. When the MRM is generated, the location of the UE may be determined based on such timing measurements that may include observation time difference (OTD) measurements. In a design, the observed delay difference for the hive can be determined based on the OTD measurements. The relative time difference (RTD) for the hive can also be determined, for example, based on RF measurements included in the MRM or a known location of a hive. The location of the UE can then be determined based on the observed delay difference, the known location of the hive, and the RTDs. Various aspects and features of the present disclosure are described in further detail below. [Embodiment] The techniques described herein are applicable to various wireless communication networks such as CDMA, TDMA, 123353.doc 200816669 FDMA, OFDMA, and SC-FDMA networks. The terms π-network and 'system' are often used interchangeably. A CDMA network may implement a radio technology such as Universal Terrestrial Radio Access (UTRA), cdma2000, etc. UTRA includes wideband CDMA (W- CDMA), low chip rate (LCR), high chip rate (HCR), etc. cdma2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA network can implement a global mobile communication system (GSM). Radio technology. An OFDMA network can implement such as Evolved UTRA (E-UTRA), Ultra Mobile Broadband (UMB), IEEE 802.1 l (Wi-Fi), IEEE 802.16 (WiMAX), IEEE 802.20, flash Radio technologies such as OFDM®, etc. These various radio technologies and standards are known in the art. UTRA, E-UTRA and GSM are described in a program named "3rd Generation Partnership Project" (3GPP) In the document of the organization, cdma2000 is described in a document from an organization named "3rd Generation Partnership Project 2" (3GPP2). 3GPP and 3 GPP 2 documents are publicly available. For clarity, certain aspects of the techniques are described below for a 3GPP network. 1 shows a wireless communication network 100 that can be a Global Mobile Telecommunications System (UMTS) network implementing W-CDMA. In the example shown in Figure 1, wireless network 100 includes three Node Bs 110a, 110b, and 110c. A Node B is a fixed station that communicates with the UE and may also be referred to as a base station, an evolved Node B (eNode B), an access point, and the like. Each Node B 110 provides communication coverage for a particular geographic area. The coverage area of Node B can be divided into smaller areas, for example, three smaller areas. The term π honeycomb can refer to the smallest unit of coverage of a node or the 123353.doc 200816669 as a node B subsystem of this coverage area, depending on the context in which the term is used. In Figure i, Node B 110a, 110b and 1 L〇c respectively servos the cells i, 2, and 3. That is, the point B 110 can be coupled to a node B aggregation point 13〇, and the node B aggregation point 130 can aggregate data and signal transmission for the node B. Further coupled to a Radio Network Controller (RNC) 14(), the radio

The RNC 140 can provide coordination and control to the Node B coupled to the RNC via the aggregation point. For example, the RNC 14 can perform radio resources and some other operational functions, and other functions for supporting communications for the UE. UE 120 can be dispersed throughout the wireless network. A UE can be stationary or mobile and can also be referred to as a mobile station, a mobile device, a terminal, an access terminal, a subscriber unit, a station, and the like. A UE can be a cellular telephone, a PDA, a wireless communication device, a handheld device, a wireless data modem, and the like. A UE can communicate with one or more Node Bs via transmissions on the downlink and/or downlink. The downlink (or front link) refers to the communication link from the Node B to the UE, and the uplink (or reverse link) refers to the communication link from the UE to the Node B. The terms, UE, and "user" can be used interchangeably herein. The parent-honey has a specific coverage area that can be determined based on the RF parameters of the bee f. The antenna is tilted down, The antenna orientation and the antenna % type affect the broadcast characteristics and thus affect the coverage of the hive. The pilot X ^ ~ ginger UE receives the pilot signal from the hive. Changing the pilot power, the owing to the hive size can cause the downlink The link between the path and the uplink is unbalanced. If the pilot power is adjusted (eg, reduced), it can correspond to 123353.doc 200816669. The uplink is manually adjusted (eg, increased to weaken the uplink). The bottom of the noise to avoid link imbalance. During a cellular phase, a traffic map and RF propagation model for the network deployment area can be obtained. The traffic map can indicate that the user can be more concentrated and can be in various ways ( For example, the area obtained by determining the position of the user, by the parent in the observation area, etc.) The term "position (1〇cati〇n)" is synonymous with, position" It can be used interchangeably herein. The scale propagation model can be used to predict the path loss of RF signals and can be based on the kumura-Hata model or some other model. The hive location can be (for example) due to the umts hive in the existing GSM hive. The deployment of the points is known. In this case, the traffic map, the RF propagation model, and the hive location can be provided to a honeycomb device such as Atol, Planet, Assett, 〇dyssey, etc. known in the art. The Honeycomb Tool can determine the RF parameters of the cells to achieve good network performance based on coverage and capacity. Alternatively, the traffic map and RF propagation model can be provided to a device such as is also known in the art.

Automatic Honeycomb (Acp) tools for Radi〇plan, Schema, AHEs〇, etc. The ACP tool can propose a honeycomb site and determine cardiac parameters so that good network performance can be achieved. In one aspect, the implementation of the hive can be performed on the existing wireless network (for example, a GSM network) by considering the user's mobility, and can be used in the existing network. A relatively accurate traffic map based on the information of the person and its location. The user location can be determined based on the positioning capabilities of the existing network that supports E_9n requirements. Traffic maps may also be obtained in other ways, for example, by observing the user in the geographic area and recording the approximate location of the user. A relatively accurate behavioral map can be obtained based on information from users on the existing network and where the delivery takes place. The mobility map can also be obtained in other ways, for example, by viewing the location of the user and the user in the geographic area. The map and the RF propagation model can be provided to a hive for external inspection and used to determine the location of the location and the 1117 parameter settings for the new hive to be deployed. The existing hive site can be reused for the new hive and can be located from the existing hive site in the new hive site. The hive plan tool can select the hive site location and the RF# number setting based on a compromise between coverage and capacity. The action ^ map can be used in various ways for the hive plan. In-design's performance metrics can be defined as a function of coverage, capacity, and mobility and can be used to select hive location and/or lamp parameter settings. The performance metric can be a function of the number of handovers at the honeycomb boundary, and the number of handovers at the honeycomb boundary can be estimated based on the action graph. For example, the I' mobility map may indicate that the measurement report message (MRM) is sent to request delivery to the location of the new hive. The number of mrms that can be sent is based on the number of copies. It may be necessary to select the position of the honeycomb site and the number of the parental deductions. Frequent handoffs of UEs in idle mode (referred to as homing, selection) consume battery and degrade call setup performance. Frequent handoffs of UEs in an efficient manner can disadvantageously provide instant services such as voice and video streaming and further reduce service coverage for the pay-over network. , 蜂 Select the location of the honeycomb site and the RF parameter settings to reduce the number of deliveries and provide a “clean” hive boundary. If moving from hive A to hive B, come to 123353.doc 200816669 The pilot signal from hive A becomes monotonously weakened and the number from the hive becomes monotonous and strong, and there is one for the two hive from the two: The parent points more than 'the boundary between the two honeycombs A and B is . If the hive receives equally strong and/or is strong in the second (four) I at the hive boundary, then the boundary between the multiple hive can be considered as, and the uncleaned ". This phenomenon is also commonly referred to as, pilot pollution, and can result in frequent and potentially fast delivery between the cells. A clean honeycomb boundary and thus no pilot contamination/low pilot pollution can be obtained by selecting the honeycomb site location and/or RF parameter settings such that a small number of pilots are significant. This may be required in areas with higher density of users and/or more mobile users. Eight In the example shown in Figure 1, three honeycombs 2, 2 and 3 may have overlapping coverage areas in _region "2. Region 112 may have a relatively high concentration of mobile users that may be indicated by traffic maps and mobility maps. This can result in frequent handovers by users in area 112 in three cells 2, 2, and 3. Figure 2 shows an example of using a traffic map and a mobility map to adjust the coverage of a hive. In this example, the coverage of such hives can be adjusted by selecting appropriate RF parameters for the hive, 2 and 3 such that there are fewer and possibly cleaner hive boundaries. This can result in less handoffs for users in the area 丨12. In general, the traffic map and the mobility map can be used to select the location of the excellent honeycomb site, reduce the boundary of the honeycomb, and place the hive boundary so that more and more can be generated. The area can be cleaned by placing a hive in an area with a dense user population or by pointing a hive to the area 123353.doc -12- 200816669 ==. Clean hive borders for highly mobile users This is because less time is available for delivery. Reducing the number of handovers may provide certain advantages, such as: more rounds, P卩¥ π 丄 夕 乂 乂 更少 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂 蜂Improved performance (eg, less breaks) and so on. Yes = the number of calls allows a good function to be used in a higher user density area or a higher usage area to move poor lamp performance to less frequent areas. RF parameters can also be set to reduce pilot contamination, rapid changes in feeding nests, coverage holes, and more. Results from the Honeycomb Weapons are generally only good/good with inputs provided to such tools (eg, traffic maps, RF propagation models, and mobility maps). These inputs may be relatively coarse in many cases. For example, traffic data may be coarse and available only at the cellular level. In addition, service areas for different types of services may be disregarded. RF propagation models may also be inaccurate for a variety of reasons. A driving test can be performed to measure RF conditions at different locations, and these RF measurements can be used to fine tune the RF propagation model. The modified RF propagation model can then be applied to the hive plan tool to update the rf parameters of the hive, which can improve network performance. However, driving tests can be time consuming and often only cover the street without covering the room. In another misconduct, after deployment, the RF parameters of the hive can be adjusted based on measurements performed by UEs in the wireless network. A UE may measure a live set, an adjacent set, and/or a beehive in a detected set. The active set may include a hive that currently serves the UE. The neighbor/query set may include a hive that the UE can hand over. The detected set may include a hive having sufficient pilot strength or quality detected by the UE 123353.doc -13 - 200816669 UE. Ue can generate and send an MRM, which can contain the following: • RF measurement for the hive _ can be used to trigger the handover of the UE, and • Timing measurement for the hive - can be used for downlink key synchronization during handover of the UE . These RF measurements can be related to pilot (4), pilot quality, and the like. The pilot strength may indicate the pilot power received at the UE and may also be referred to as the received signal power (RSCP). The pilot quality can indicate the quality of the received pilot at 1^, which takes into account the received pilot power and interference. Pilot quality can also be referred to as the ratio of energy to total noise per chip (Ec/N〇). 1; £ may also contain other types of measurements, such as received signal strength indication (RSSI), signal-to-interference ratio (SIR), etc. For the sake of simplicity, the following description assumes the use of Rscp and Ec/No. Timing measurements can be given in a variety of formats as described. The UE may obtain Rscp measurements and measurements for any number of cells (e.g., active, adjacent, and/or beehives in the set of debts). Yeah also has access to timing/synchronization information for these hives. The ue can send the measurements and associated timing information in an MRM to, for example, a service hive or RNC. These RSCp measurements can be used to calculate path loss and to establish accurate ambiguity. The isometric 0 measurement can indicate load/interference on the downlink and can be used to establish an accurate load map. The UE may generate and develop MRM periodically or when triggered. Since the MRM contains timing information for the hive and the UE ID, the location of the UE can be determined based on the measurements as described below. In addition, Mrm can be used to determine the mobility of the fairy and can be used to construct an action map. 123353.doc -14- 200816669 Figure 3 shows a design of a process 300 for determining the number of hives of a hive by considering the mobility of the UE. The mobility information for the UE may be determined, for example, based on the MRM for handover delivered by such ue (step 312). For example, the location of the UE may be determined on an MRM basis as described below, and the mobility information may be determined based on the location of the UE. The mobile information can indicate ^ the location of the UE during handover. • At least one hive may be determined based on the UE's mobility information (less than one RF parameter (eg, antenna downtilt, antenna orientation, antenna pattern, pilot power, noise floor, etc.) (step 314). The RF parameters may be further determined based on the RF information, traffic information, RF communication information, etc. of the ue. The MRF may be based on the MRM based on the pilot strength measurement, the pilot quality measurement, and the like. The (etc.) 1^ parameter can be adjusted to have stronger coverage, mobile coverage boundaries, j^V frequency pollution, increased coverage, increased capacity, reduced or mobile coverage holes, etc. in certain areas. The (equal) RF parameter achieves excellent network performance based on a compromise between coverage, capacity ί / and turbulence, for example, reducing the number of people, the number of fathers, and the idle mode. The number of hive re-selected in the 〇 汁 汁 'process can collect the MRM collected from the UE to estimate the UE location and 'identify such as 暮 4S,, - 4 _ κ, /5* music, dog growth hive (oversh〇〇ting cell ), over the sound + after the present RF issues with range and capacity limitations. These RF issues can lead to disconnection, beer luxury

Rp moxibustion ί X majority. The effect of the antenna downtilt, antenna orientation and/or pilot power change on rf 123353.doc -15-200816669 can be used, for example, using a hive plan tool. The UE position may be accurate enough to predict the deita in the honeycomb antenna gain due to the antenna downtilt or orientation. Based on the UE location, the average inaccuracy of the clamping mechanism, the configuration of the hive site, etc., the probability density function of the delta in the gain of the honeycomb antenna from which the antenna is tilted down or the orientation is changed ( PDF). These parameters can then be adjusted to minimize an appropriate cost function based on the delta in the cellular antenna gain pDF of the estimated UE position. It is possible to prevent the progress from weakening the rf change in the weaker RF region (based on the coverage and the maximum loading on the region) by selecting the appropriate level of confidence. In one design, a simple straight line pair (line_〇f_site) (L〇s) type can be used as an RF propagation model to calculate the change in the gain of the honeycomb antenna caused by one of the RF parameters. In a macro-honey environment, most of the scatter can occur very close to the UE. Therefore, an L〇s model may be sufficient. Slow and rapid degradation caused by scattering and multipath can be considered by using RF measurements from the UE. In a design, if you estimate the old Han? With the parameter settings, the previously set amount can be stored and reused. In the re-state, the RF parameters of the hive can be dynamically adjusted based on the manned conditions of the hive in the wireless network. These loading conditions can be determined based on UE2Mrm, scheduling information, and the like. These RF parameters can be dynamically adjusted to achieve the same or similar coverage while achieving good network performance. Figure 4 shows the process of adjusting parameters based on the loading conditions. Based on the message from the UE, it is determined that at least - the hazard of the hazard and/or other conditions in the 123353.doc -16-200816669 line network (step 412). For example, the UE may send a message to report action information (eg, location), good conditions (eg, RSCP and (4), performance (eg, flux and BLER), etc. Such messages may be MRM and/or Other types of messages. The UE may send such messages for various purposes such as parent delivery, location reporting, network performance monitoring, and tone modulation, etc. The message from the UE may be used to load the homing to the hive. Conditions and / or other conditions. Can be such

Based on the loading and/or other conditions, the at least one RF parameter of the at least one hive is adjusted (step 414). The UE may send an MRM during normal operation to support handover. Timing measurements in these mrms can be used to determine the UEi position, and the UEi position can be used to adjust the parameters of the hive. Timing measurements for UMTS can be generated as described below. Figure 5 shows an example of the timing of one of the UEs and two cells in the wireless network 100. In UMTS, the transmission schedule for each hive is divided into frames, each frame having a duration of approximately 1 millisecond (ms) and covering 38,400 chips. Each frame is identified by a 12-bit system frame number (SFN). The SFN is incremented by one for each frame, ranging from 〇 to 4095' and wraps around after reaching 4095. The SFN is sent once every 20 ms on a primary common control entity channel (P_CCPCH). In UMTS, the hives can operate asynchronously. In this case, the frames of the different honeycombs as shown in Fig. 5 may not be time aligned and may have different frame numbers. The transmission schedule of the UE is also divided into frames, each of which is identified by a number of frames (CFN) of 123353.doc -17-200816669. When a dedicated physical channel (DPCH) is established for the UE, the CFN is initialized based on the SFN of a servo cell. The CFN is maintained by the UE and the RNC and is not transmitted over the air. The UE may determine an SFN-CFN observation time difference (OTD) for a given hive m, as follows: OTDW = OFFW. 38, 400 + TW, Equation (1) where OTDm is the OTD for the hive, and OFFw is the OTD for the hive m One of the frame-level parts, and one of the chip-level parts of the OTD for the hive m. OTDw is the difference between the timing of the cellular m and the timing of the UE (as observed by the UE and given in units of chips). The chip-level portion of the OTD can be given as follows:

Tw = (Tuetx - T.) — 'Special Formula (2) where Tuetx is the start of an uplink DPCH frame for the UE, T〇 is a constant defined as equal to 1024 chips, and T RxSFNm is The beginning of the P-CCPCH frame for the hive m before the time constant Tuetx_T〇 observed at the UE. The time constant Tuetx-To is the beginning of a DPCH frame for the downlink of the servo cell. As measured at the UE, the start of the uplink DPCH frame for the UE is set to T〇 chips after the start of the downlink DPCH frame. The time constant TUETx is used as a time reference for measuring each hive to be reported. The frame level part of the OTD can be given as: OFFm 2 (SFNw - CFNTx) mod 256, Equation (3) where CFNtx is the uplink key DPCH frame starting at time Tuetx 123353.doc -18 - 200816669 CFN , and SFN" begins at time TRxSFNw for the SFN of the P-CCPCH frame of the hive m. As shown in Figure 5, the UE receives a P-CCPCH frame for the hive m after a delay of %, which is the propagation delay from the hive m to the UE. The P-CCPCH frame is transmitted by the cell m at time TTxSFNw and received by the UE at time TRxSFNm where % = TTxSFNaw - TRxSFNm. The UE can perform RF and OTD measurements on any number of cells. The UE may send such measurements to the servo cell in an MRM. When generating MRM (also referred to as ''location MRM'), OTD measurements can be used and RF measurements can be used to determine the location of the UE. Since the UEs can be in different locations for different MRMs, positioning can be performed for each MRM Figure 6 shows a system model for a UE and three cells 1, 2 and 3. The UE can obtain SFN-CFN OTD measurements for the three cells as described above. These OTD measurements can be expressed as: OTD^l -(Τα+η), Equation (4) OTD^Tue-CTq+z^), and OTD3 =1^-(TC3+r3) 5 where the time reference at Tue&UE corresponds to TUETx - To TC1, TC2 & TC3 are time references for hive 1, 2 and 3, respectively, ~, τ2 and 1:3 are propagation delays for hive 1, 2 and 3, respectively, and OTDi, OTD2 and OTD3 are for hive 1 respectively. OTDs of 2, 3, and 3, as shown in the equation group (4), the OTD is a measurement of the timing of 123353.doc •19-200816669 of the hive as observed at the UE and includes propagation delays for such hives. The relative time difference (RTD) between the honeycombs can be defined as: RTD21 = TC2 ^TC1 = OTD1 -OTD2 -(r2 -r,) = OTD, -OTD2 -^21 » Equation (5) RTD31 = TC3 - TC1 == OTD]- OTD3 - (r3)==OTDi - OTD3 - 531, where 丨 为 is the observed time difference of arrival (OTDOA) for hive 2 and 3 relative to hive 1, and RTD21 & RTD31 *Not for RTDs relative to Honeycomb 1 for Honeycombs 2 and 3. In Equation (5), OTDs are known from MRM, and RTDs and OTDOAs can be determined as follows. RTDs can also be called The timing relationship. OTDOA can also be referred to as the observation delay difference. The measurement in the MRM can be used to determine the location of the UE for the MRM, or simply the MRM location. The MRM can provide the MRM location between several hives (usually two OTDs to between eight hives and RF measurements for such hives. The location of the hive can be known. These different types of information can be used to locate the MRM. In one design, the MRM position can be estimated as follows: A1 · (For example) determining the timing relationship or RTD between the hives based on a start-up technique, and A2. (for example, using an iterative algorithm to estimate the MRM position based on the RTD and the OTD. Step A1 can be performed as follows) A2. In one of the designs of step A1, the reported in the MRM can be determined as follows The temporal relationship between the hive: 123353.doc -20- 200816669 Β1· Estimate the distance between the MRM position and each hive based on the amount of hive and an rF propagation/path loss model, B2. The estimated distance is based on the estimated mrm position, B3. The propagation delay of each hive is estimated based on the MRM and the hive position, and B4. The RTD between the hive is determined based on the propagation delays. For step B1, the path loss for each of the nests reported in the MRM can be determined as follows:

Lw=pw+Aw(x,y)-RSCPw, Equation (6) where Pm is the pilot power of the hive,

Aw(x, y) is the antenna gain of one of the honeycombs as a function of the MRM position (χ, force,

Rscpm is the RSCP from the pilot of the hive, and the path loss for the hm, in decibels (dB). The antenna gain Aw(x, y) can be calculated based on a base station ephemeris and a straight line pass (LOS) assumption. The distance between the MRM position and each hive can then be estimated based on the path loss of the honeycomb and the RF propagation model, as follows: Μ f, = l〇ll0wJ, Equation (7) where π is the one-way loss index, which can Set to π = 3.84, r is a path loss constant, which can be set to Γ = 138·5 dB, and ~ is the estimated distance from the hive based on the RSCP measurement. For step B2, the MRM position can be estimated based on the estimated distance from the hive obtained in step B1. If there is no error in the estimated distance, it will intersect 123353.doc -21 - 200816669 at a single point, which is provided as the MRM position. However, the estimated distance will likely have errors and the MRM position can be determined to minimize these errors. Figure 7 shows an example of a three-sided measurement for estimating the mrm position based on the estimated distance from the hive. For the sake of simplicity, the following description assumes a 2-dimensional (2D) coordinate with a degree of I and latitude (eg, (χ, y) for the MRM position and (Xm, for the position of the hive m). In general, The coordinates are given in 2D as described above or in 3D (3D) with longitude, latitude and altitude (for example, (X, y, z) for the MRM position). The example shown in Figure 7. The honeycombs 1, 2, and 3 are located at coordinates (Χι, Υι), (χ2, d, and (X3, Yd, the coordinates are known. The MRM positions are at coordinates & y), coordinates ( X, y) is to be estimated. The calculated distance between the hive and the "^^ position & illusion can be expressed as: 2yYw, equation (8) where 1^ is the calculated distance between the MRM position and the hive w The MR Μ position can be determined such that the difference between the estimated distance from the hive and the calculated distance is minimized. This can be achieved by minimizing the following error metrics: E(x,y) =lx2 乂2丨/w = 1 = ΣΐΧ: +Χ2-2xXw+Yw2”2 a 2yYw-f2| Equation (9) where E(x, y) is an error metric and Μ is the number of hives in the MRM. If the MRM contains three or three More than one hive For the measurement, equation (9) can be used. If the MRM includes measurements for three or fewer honeycombs, there is confusion at the MRM position. In addition, because the antenna gain is Κχ, ^123353.doc -22- 200816669 MRM position A function, so equations (6) through (9) can be iterated multiple times to minimize the error metric E(x, y). The MRM position can be obtained after all iterations have been completed. For step B3, it can be like the equation ( The distance between the MRM position obtained from step B2 and each hive is calculated as shown in 8). The distance from each hive can then be converted into a propagation delay as follows: , Equation (10) where C is the signal propagation The speed, which is cdxlO8, and L is the propagation delay from the hm to the MRM position, as shown in Figure 6. For step B4, the timing relationship between the hives can be calculated as follows: RTD, OTD, - OTDw - , Equation (1 1) where RTD- is the RTD for the hive relative to the reference hive. One of the MRMs can be used as a reference hive/, and the RTD of each remaining hive in the MRM can be calculated. / can be servo honeycomb, the strongest honeycomb, the earliest honeycomb, etc. In equation (11), the OTD may be from the MRM, and the propagation delay may be obtained from step B3. A plurality of (K) MRMs may be received from the UE. The RTD may be calculated for the reported hive in each MRM. The average of the RTDs is taken from the K MRMs to improve the accuracy of the RTD estimation, as follows: RTDm/, avg=|; W, .RTDwa, equation (12) k = \ where RTDwu is for the HH1MRM for the hive The RTD of m and z• is a weight for the third solid MRM, and 123353.doc -23 - 200816669 RTDwz, avg is for the hive] V1RM for the hive and ·, / RTD. z Average Equation 02) Shows the mechanism of averaging over multiple MRMs. This averaging can also be performed in other ways. In another mechanism, the intermediate value RTD heart can be selected without selecting the average and providing an intermediate value of RTDm!., avg. In the re-mechanism, the mapping function can attenuate measurements away from the intermediate value. In any case, averaging over multiple MRMs can improve accuracy by smoothing the effects of shadowing and rapid decay. The weight I can be chosen to give more weight to a more reliable RTD. For example, a more accurate estimate of one of the MRM locations can be obtained from an MRM with more cells, and more weight can be given to the RTD obtained from this MRM. The duration of the averaging may be limited such that the clock drift at the hive is negligible. In the step AR-design, the timing relationship between the honeycombs can be determined based on the rough estimate of the MRM position. For example, the position of the servo cell, the strongest hive, the earliest hive or some other hive can be used as a rough estimate of the MRM location. As a further example, the coverage center of the servo cell, the strongest hive, the earliest hive or some other hive can be used as a thick chain estimate for the MRM location. As a further example, the random starting position can be used as a thick chain estimate for the MRM location. In any case, the rough estimate of the MRM position can be used to determine the thick chain distance from each hive, as shown in equation (8). The rough distance can then be converted to a coarse propagation delay as shown in the equation (ίο). The RTD for the paired honeycombs can then be derived as shown in equations (1)) and (12). Hives belonging to the same Node B usually have a fixed and most likely time offset of 123353.doc -24- 200816669. This information can be utilized in several ways. First, the number of unknowns can be reduced and more measurements can be used to estimate these unknowns, which can improve accuracy. The _man, only the first _ multipath can be considered, and the signal components of different homings arriving at the same node B can be discarded. For step A2, a difficult position can be estimated based on the iterative algorithm, as follows: C1. Calculate the MRM position based on the OTD measurement in the MRM,

U C2. Estimating the distance between the MRM position and the hive position and converting the distance into a propagation delay, C3. determining the timing relationship between the hives based on the propagation delays, and C4. If the MRM position converges, Then exit, or otherwise return to step ^. For step ci ', the observed delay difference for each-non-reference honeycomb w can be estimated as follows: hri=OTDr〇m, equation (13) where for the first iteration, the lamp ^ can be set to the RTDmz obtained from the step, Avg, and the difference in observation delay between the hive and the reference hive. The relative pseudorange can then be calculated for each non-referenced hive as follows: ^mi = smi. c = rw -

2 A Equation (14) where "the relative pseudorange between the hive_reference bee κ is in equation (10), τ is the 乂 for each non-reference hive, ... is the number and depends on the MRM position (x, y) Ffi?S, as shown in equation (8), may determine at least two relative pseudoranges (eg, & and A31) and use the at least two 123353.doc • 25-200816669 relative pseudoranges to estimate the MRM location. A relative pseudo-range is available, for example, by Υ·Τ· Chan and KC Ho in a title entitled ''A Simple And Efficient Estimator for Hyperbolic Location,'' (IEEE Trans. Signal Proc., Vol. 42, No. One of the closed form solutions described in the paper No. 8, March 1994) calculates the MRM position based on the closed form solution. If more than two relative pseudoranges are available, one can be such as the least mean square (LMS), linear minimum mean square error ( The MRM position is calculated based on the iterative technique of LMMSE), Recursive Least Squares (RLS), etc. The LMS and RLS techniques are by Simon Haykin in the title "Adaptive Filter Theory" (3rd edition, Prentice Hall, 1996). Described in the book. In any case, two unknowns X and y for the MRM location can be calculated using two or more equations for the relative pseudorange. For step C2, the distance rw between the MRM position obtained from step C1 and each of the honeycombs can be calculated as shown in equation (8). The distance from each of the hives can then be converted to a propagation delay ^ as shown in equation (10). For step C3, the timing relationship RTDw between the hives can be calculated based on the propagation delay obtained in step C2 and the OTD from the MRM, as shown in equation (11). The RTD obtained from the OTD measurement in step C3 can be more accurate than the initial RTD obtained from the RF measurement in step B4. The average of the RTDs for the hive can be taken, for example, on multiple MRMs as shown in equation (12). For step C4, a change in the MRM position between the current iteration and the last iteration can be determined. If the change is below a threshold, convergence can be declared and the MRM position from the current iteration can be provided as the final estimate of the MRM position 123353.doc -26-200816669. If the change exceeds the threshold, another iteration can be performed starting at step C1.

For the sake of clarity, a special design for estimating the position of the MRM based on the SFN_SFN OTD measurement has been described above. The MRM position can also be estimated based on other timing measurements and/or using other positioning techniques. The above design estimates the 2D coordinates (X, y) of the MRM position. Although there is an additional unknown for elevation z, the 3D coordinates (X, y, z) of the MRM location can be estimated in a similar manner. The estimated south of the MRM location can also be obtained via the Google Earth map or some other technique. In another design, the UE may report Type 1 SFN-SFN OTD measurements for the hive. In this design, the frame-level portion of Type 1 SFN-SFN 0TD can be given as: 0FFw=SFN, -SFNW, Equation (15) where SFN/ and SFN/ are reference hive ί and non-reference hive m respectively SFN. The chip-level portion of Type 1 SFN-SFN OTD can be given as: - TRxSFN/ » Specialized (1 6 ) where TRxSFNw is the beginning of a P-CCPCH frame for non-reference cells, and TRxSFNi is a target Refer to the beginning of the hive/p-CCPCH frame. In yet another design, the UE may report Type 2 SFN-SFN OTD measurements for the hive. In this design, the chip-level portion of Type 2 SFN-SFN 0TD can be given as: Tw = TCPICHRxw - TCPICHRx/ where TcPICHRxm is an equation (17) The P-CPICH frame received from the hm is opened 123353 .doc -27- 200816669 and TCPICHRX/ is the beginning of a self-homed/received P-CPICH frame. For the system model shown in Figure 6, the Type 2 SFN-SFN OTD measurement can be defined as: 0 D.0821 = (D. 2 He 2 Bu (1^+ Magic, and Equation (18) OTDS31 = (TC3 + r3) - TCDS + & The OTD measurement sent in the MRM. The observed delay difference can be given as: 41=W〇TDS21-RTD21, and equation (19) δ31 =τ3 — τι = OTDS31 - RTD31 ο The observation from equation (19) can be used The delay difference estimates the MRM location, for example, as described above. The UE may also report measurement of UE Rx-Tx time difference, measurement of UE GPS timing for cellular frames for UE positioning, measurement for round trip time (RTT), Measurements of UTRAN GPS timing for cellular frames for UE positioning, etc. These SFN-CFN measurements, Type 1 SFN-SFN measurements, Type 2 SFN-SFN measurements, and other measurements are described in the publicly available title. 'Physical layer - Measurements (FDD), '' (May 5, 2007) in 3GPP TS 25.215. Figure 8 A design for a process 800 for estimating an MRM location is shown. An MRM is provided that includes timing measurements for a plurality of cells, wherein the MRM is transmitted by a UE when used for handover or when triggered (step 812) 123353.doc • 28 - 200816669 For example, a UE may be configured to periodically transmit MRMs that may be used by a wireless network to assess general coverage and/or for other purposes. Timing measurements may include SFN - CFN OTD measurement, SFN-SFN OTD measurement for Type 1 or 2, etc. When MRM is generated, the location of the UE may be determined based on the timing measurements in the MRM (step 814). For step 814, timing measurements may be based. Determining the observed delay difference t for the hive in the MRM. The RTD for the hive can also be determined, for example, based on RF measurements included in the MRM, a known location of a hive, etc. can then be observed as described above The location of the UE is determined based on the delay difference, the known location of the cells, and the RTDs. The MRM can be collected from UEs in the wireless network. Each MRM containing measurements for a sufficient number of cells can be determined as described above. Bit . The position and the like can be generated based on the MRM load / traffic pattern and operations of FIG. MRM measurement in the RF also generated based on the RF FIG. These various maps can be applied to the Honeycomb Tool and use these various maps to adjust the RF parameters of the hive to improve network performance. In particular, as described above, the RF parameters of the hive can be adjusted based on a performance metric that is a function of one of coverage, capacity, and mobility. The use of MRM for RF parameter adjustment can be advantageous for a number of reasons. First, the MRM is sent for normal UE operation and thus may not incur the additional expense of obtaining such MRMs. Secondly, MRM provides coverage of the π area that the payment consumer goes to, and includes areas where the driving test vehicle is inaccessible (eg, indoor) and areas with low user density. Capabilities of capturing indoor users via MRM are available This may be beneficial for a more accurate RF model in the room 123353.doc -29- 200816669 because the indoor link tends to be weaker than the outdoor link. Third, the UE can be triggered for the following downlink and The uplink channel metrics are based on the transmission of MRM to support intra-frequency, inter-frequency and inter-system handover. Therefore, location measurement can be used in weaker areas where RF optimization can be more beneficial. It can also be used by using MRM. Various other benefits are obtained for RF parameter adjustment. An active set can be maintained for a UE, and the active set can include one or more servo cells for the UE. In UMTS, if the following conditions occur for a predetermined period of time, then A new hive can be added to the active set: Pilot_Ec/No > Best—Pilot—Ec/No - Reporting_Range + Hysteresis_EventlA, Equation (20) where Pilot_Ec/ No is for the new hive, Best_Pilot_Ec/No is for the best hive in the active set, Reporting_Range is the threshold for the delivery, and Hysteresis_EventlA is the hysteresis for the hive. If the following conditions occur for a predetermined period of time, Remove an existing hive from the active collection:

Pilot_Ec/No < Best_Pilot_Ec/No - Reporting-Range + Hysteresis_EventlB, Equation (21) where Hysteresis_EventIB is a hive removal lag. The reporting scope and lag can be set by the wireless network and applies to all hives to be added to or removed from the active set. In yet another aspect, the MRM from the UE can be used to determine a Cellular Individual Offset (CIO) that can be a parameter affecting the handover. The CIO can be used to trigger the UE to send an MRM for handover. The CIO can also be used to add a hive to the effective set of UEs 123353.doc -30· 200816669. In the area with poor topology (9), for example, the n-face main body of the coastal city, high skyscrapers, hills, etc.) deploy one: network. In such areas, pilot fouling, and using appropriate hive plans are also difficult to improve. At one point, the UE can quickly observe the changing RF conditions of the different honeycombs in the needle-small area. ^ In this case, if the hive is not added quickly enough to the effective set, then the disconnection may be seen. Medium (10) can be used to allow in the effective set of - UEs with the presence of pilot pollution Μα(4)#. (10) can be used to adjust the offset used to add the hive in the active set so that the hive can be added earlier. CI0 can be derogated to be applicable only to 宜丄厶丄厶@人, for an effective collection composition, or for different effective collection compositions. For example, ci〇 can be defined such that it is in-pilot Certain hives may be added earlier in a particular area where contamination is common, and this particular area may be determined based on the presence of certain hive. Various rules may be used to determine CI0. For example, a type of measurement report (4) may be received first ( To add or exchange _ honeycombs, followed by receiving - type 2 〇 or ^, measurement report (to away from (10) gamma .... This situation can indicate too late to add or parent to change the nest 'i can set CI 〇 so that the hive can be added as soon as possible. The use of CIOs allows for the example of tailoring of handover performance over the entire wireless network. a, which reduces the range of handover reports over a large area so that the average number of hives in the effective collection of the eve is reduced and used to support soft The handover CTO can be used in areas with pilot pollution to ensure that the hive is included early in the active set to improve call retention performance. 123353.doc -31 - 200816669 In another aspect, the inter-system handover threshold setting of the cellular level can be determined using the MRM from the UE. The system can be determined based on the network environment (eg, coverage vulnerability, outdoor to indoor conditions, coverage boundaries, etc.) The inter-system handover threshold is set. The inter-system handover threshold can be lower in the coverage vulnerability than in the outdoor-to-indoor scenario to trigger handover earlier in the coverage vulnerability and achieve a constant call rate. Advance threshold to reduce inter-system handover in UMTS coverage. Inter-system handover threshold for hive reselection during idle mode can also be set to achieve good call setup performance, extend UEMT coverage, and improve battery For example, if there is pilot pollution in the UMTS that cannot be adjusted via RF parameters, the inter-system hive reselection and handover threshold can be set to trigger early handover to GSM, and GSM mobility can be set. The threshold is such that the UE stays in GSM. Conversely, if the UMTS coverage is clean, the inter-system hive reselection and handover threshold can be actively set. Facilitating the handover to UMTS. Figure 9 shows a design of a process 900 for automatically determining threshold settings using MRM. UEiMRMs from a wireless network are available (step 912). These MRMs can be determined based on these MRMs. At least one threshold setting for at least one of the cells in the wireless network, wherein the at least one threshold setting is for handover of the UE (step 914). The at least one threshold setting may be included for Adding at least one of the hive to a ciq of the active set of the UE. Alternatively or additionally, the at least-pre-limit setting may include selecting at least one intersystem handover for the at least-homing of inter-system handover Limit setting. The at least one threshold setting can be determined to reduce the number of 123353.doc •32-200816669 for uE2 handover, 'reducing the number of disconnections', improving call setup performance, and the like. In yet another sorrow, the pilot power level from the UE2 MRMS beacon can be used. MRM can be used to identify areas with pilot contamination. The pilot power of one or more of the cells in the area can be adjusted to reduce pilot pollution. The UEi MRM can be captured or collected in a variety of ways. In one design, a network probe can be used to capture MRM in a wireless network. A network probe is a device that collects data in a wireless network for performance monitoring and/or other purposes. Referring back to FIG. 1, a point B 110 can receive from the UE2 MRM and can forward the MRMs to the RNC 14 via the Node B aggregation point 130 (^rnc 14 can use the MRMs to make handover decisions for the UE and/or For other purposes, Node B 110 can establish an interface with the RNC 14 via the IuB interface, which can be aggregated before entering the RNC. Can be installed in the Node b aggregation point i3Q (or attached to the Node B aggregation point 130) A network probe 128 captures the MRM of the entire wireless network being loaded using the network probe 128. The network probe 128 can provide the MRM to a server 132, which can Processing the MRMs to derive load/traffic maps, maps, mobility maps, etc. and/or adjust the RF parameters of the hive. The network probe 128 may already be used for network performance monitoring and/or other functions and thus may be capable of The MRMs are captured at small incremental cost. The network probe 128 can be any commercially available network probe 'such as GeoProbe from Tektronix, Inc.. It can also be collected in other ways (eg, using Telnet on the RNC) These]VIRM. In UMTS, define 512 primary scrambling codes (PSC) and Use the 512 primary scrambling codes to distinguish between different cellular downlink transmissions. If only $123353.doc •33 - 200816669 PSC is used in a wireless network, then the MRM can be attributed to PSC. The only hive based on the base. If more than 512 PSCs are used, the MRMs may not be attributed to the only hive based on the PSC. In this case, the Hive ID of a PSC at a Node B and a Node B ID Establish a relationship. When collecting MRM with a network probe, the hive ID can be assigned to the PSC based on the node B ID. The report of the hive ID in the MRM can be activated. After capturing a hive ID (for example, at Collecting the MRM of a UE (identified by its temporary IMSI) for a specific duration for the connection establishment of the UE. The neighbor list of the UE can be tracked by capturing the measurement control message, for example, the neighbor list can have a high probability Uniquely identifying the set of Node B. Figure 10 shows a design of a process 1000 for collecting MRM. The network probe can be used to collect, for example, a plurality of Node Bs sent by the UE to a wireless network. The Node B is forwarded to a Node B The MRM of the aggregation point (step 1012). The collected MRM may be provided to a server for processing (step 1014). The MRMs may be sent by the UE for handover and may be used to adjust the servos by the Node Bs. RF parameters of the hive. In another design, the MRM may be captured by having the UE send the MRMs to a designated server (eg, server 132). An application executing on the UE (eg, action) The window can capture the MRMs and send the MRMs to the server in the air. The server can then process the MRMs to obtain load/traffic maps, RF maps, mobility maps, etc. and/or adjust the RF parameters of the hive. 11 shows a block diagram of one of the UEs 120, which may be one of the UEs in FIG. On the uplink, the data to be transmitted by the UE 120 and the 123353.doc -34-200816669 f signal transmission (eg, MRM) may be processed by an encoder 1122 (eg, trellis, flat code, and parent error) and Further processing (e.g., modulation, channelization, and scrambling) is performed by a modulator (MOD) 1124 to produce an output chip. A shooter (TMTR) 132 can adjust (e.g., convert to analog, filter, amplify, and frequency upconvert) the output chips and generate an uplink signal that can be transmitted over the daily line 1134. On the downlink key, the antenna (1)* can receive downlink signals from the Node B 11G and other nodes. A receiver (RCVR) U36 can adjust (eg, filter, amplify, frequency downconvert) and digitally receive signals from line A 1134 and provide samples. A demodulation transformer (DEM〇D) U26 can be processed (eg, The samples are 'de-scrambled, channelized, and demodulated' and provide symbol estimates. A decoder" can process (eg, 'deinterleave and decode) the symbol estimates and provide decoded data. Encoder 1122, modulator 1124, demodulation ι 26 and decoder 1128 may be implemented by a data processor 112.
