  The following relates generally to wireless communications, and more particularly to providing idle mode mobility management in multiple mobile communication environments.

  Wireless communication systems are widely deployed to provide various types of communication content such as, for example, audio content and data content. A typical wireless communication system may be a multiple access system capable of supporting communication with multiple users by sharing available system resources (eg, bandwidth, transmit power). Examples of such multiple access systems may include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, and the like.

  In general, a wireless multiple-access communication system can simultaneously support communication for multiple mobile devices. Each mobile device can communicate with one or more base stations via transmissions on forward and reverse links. The forward link (ie, downlink) refers to the communication link from base stations to mobile devices, and the reverse link (ie, uplink) refers to the communication link from mobile devices to base stations. In addition, communications between mobile devices and base stations are established via single input single output (SISO) systems, multiple input single output (MISO) systems, multiple input / output (MIMO) systems, etc. Is possible.

  One important aspect of mobile communication technology is managing interference between transmitters. For example, a typical cell at a cellular telephone site utilizes multiple transceiver base stations to communicate with user terminals within that cell. The transmission area of a base station typically overlaps so that a single receiver often acquires several overlapping signals at a given time. Thus, signal interference potentially reduces signal clarity in such a receiver and reduces cell communication quality if left unmodified.

  There are many mechanisms for reducing inter-site interference. Some mechanisms require utilizing MISO and MIMO transceivers that can withstand higher levels of interference with improved signal analysis at the receiver. Newer modulation techniques, such as orthogonal multicarrier modulation (eg, utilized with orthogonal frequency division multiplexing [OFDM]), can effectively reduce signal interference. OFDM uses orthogonal subcarrier frequencies to greatly reduce crosstalk interference between carrier signals. Another technique involves requesting a transmission power reduction of a basic interferer on one or more channel resources. Overlapping signals on channel resources can often be tolerated at the receiver if the transmitted power of the interference source is maintained within an acceptable range.

  However, mobile communication systems are always in flux as new research and technologies are discovered. Architectural changes in mobile technology are implemented to increase data rates, bandwidth, or evolve into all data communications. The interference problem usually has to be revisited for each new technology to determine if the balance provided by previous interference management mechanisms will be disturbed. Signal interference management is therefore an ongoing problem and requires new solutions as new mobile communication technologies are implemented.

  The following presents a simplified summary of such aspects in order to provide a basic understanding of one or more aspects. This summary is not an extensive overview of all contemplated aspects, and is not intended to identify key or critical elements of all aspects or to delineate the scope of any or all aspects.

  Various aspects are now described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. It may be evident, however, that such aspect (s) can be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more aspects.

  In addition, various aspects of the disclosure are described below. It should be understood that the teachings herein can be implemented in a wide variety of forms, and that any particular structure and / or function described herein is merely an expression. Based on the teachings herein, one of ordinary skill in the art will be able to implement the aspects disclosed herein independently of any other aspect, and two or more of these aspects may vary. It should be understood that they can be combined in various ways. For example, any number of aspects described herein can be used to implement an apparatus and / or implement a method. In addition, in addition to one or more aspects described herein, or using other structures and / or functionalities other than those aspects, an apparatus may be implemented and / or a method. Can be implemented. By way of example, many of the methods, devices, systems, and apparatuses disclosed herein determine a RUM accumulation rate for one or more sectors of a mobile network based on performance metrics of the multiple sectors. It is explained about the situation. Those skilled in the art will appreciate that similar techniques can be applied to other communication environments.

  The present disclosure provides for implementing resource utilization fairness among sectors of a mobile access network (AN). The fairness may be based at least in part on one sector performance metric of the mobile AN compared to another sector's performance metric. In at least one aspect of the present disclosure, resource utilization fairness establishes and / or adjusts the accumulation of interference avoidance credits (eg, with resource utilization messages [RUMs]) for sectors of the mobile AN. Can be implemented. Interference avoidance credits can be used to correct interference between adjacent sectors of a wireless AN. In one example, interference avoidance credits that require a sector to modify transmit power for a subset of radio resources can be issued to neighboring sectors. This interference avoidance credit can specify a particular resource for reduced interference, a modified degree of transmit power, or both. In another example, this interference avoidance credit can result in the sector modifying its own transmit power for a subset of radio resources. Since interference typically occurs as a result of the relative signal level obtained at the receiver, the modification of the sector's own transmit power can also affect interference at the terminal device served by the sector. . In addition to the foregoing description, generating interference avoidance credits may lead to no action taken by the sector (eg, no correction or a correction request to correct the transmit power). There is. Determining what type of treatment is most appropriate depends on the performance metric of the adjacent sector, the performance metric of that sector, the aggregate performance metric of multiple sectors, as described herein. It may be based on observed interference, sector load, etc.

  An example of the interference avoidance credit is RUM. A RUM is a message issued to and / or by a wireless communication device for the purpose of instructing nearby transmitters to reduce their transmission power. Typically, the decision to issue a RUM is based on signal interference at the communication device resulting from one or more interfering transmitters. A device receiving a RUM can reduce its transmit power by a predetermined factor that should reduce interference in the device issuing the RUM. To implement fairness, multiple sector performance metrics should be compared to determine if one or more sectors are flawed with respect to other sectors or sector aggregation. Is possible. RUM accumulation, issuance, and / or weighting, or interference avoidance credits (including modifications to the sector's own transmit power) are usually adjacent to faulty sectors (eg, sectors with relatively low performance metrics). Can be adjusted to mitigate being overly disturbed by RUMs issued by matching sectors, or to mitigate accumulating / issuing excessive numbers of RUMs without flawed sectors It is.

  It should be understood that a wireless AN can utilize both a reverse link (RL) RUM and a forward link (FL) / downlink (DL) RUM. The FL / DL RUM is a RUM transmitted to an interfering AT by a radio AM base station. As described in detail below, the AT receives the FL RUM and determines whether to follow that RUM. If the RUM is followed, the AT can reduce power on the RL channel to reduce interference at the issuing base station (and other base stations near the AT, for example). Conversely, an RL RUM is directed to one or more neighboring base stations of a wireless AN by an AT (eg, utilizing a RUM accumulated by a serving sector associated with the AT). publish. The base station can determine whether to follow RL RUM and reduce FL transmit power if RL RUM is followed. As discussed below, the accumulation and / or adjustment of the RUM accumulation rate or RUM issuance rate may be applied to either or both of the DL RUM and FL RUM.

  In a mobile environment, access terminals (ATs) and base stations increase transmit power at various times based on various factors. For example, the base station can receive a signal from the AT indicating that the signal transmitted by the base station was received at the AT with very low power. This allows the base station to increase transmission power to improve communication with the AT. Furthermore, if the device transmission has low signal-to-noise ratio (SNR) characteristics at the receiver, the signal transmission power can be increased. However, increasing the transmit power can cause interference in nearby devices. Thus, the RUM provides the device with feedback indicating that the device's transmit power is too high for other neighboring devices.

  However, RUM can have drawbacks. For example, a single device may monopolize sector communication by issuing too many RUMs to nearby devices. If other devices excessively reduce their transmit power based on multiple received RUMs, the communication quality of such devices can be damaged. Therefore, the accumulation and / or publication of RUMs for devices must be managed so that a small number of devices do not reduce the transmission quality for neighboring devices. In effect, the principle of fairness can be exercised to provide good overall communication to devices in the wireless AN.

  In one aspect of the present disclosure, the number of RUMs that a sector of a wireless AN can issue at a given time is accumulated for that sector (eg, a RUM “token associated with that sector, so to speak) Depends on the number of such RUMs (in the "bucket"). The rate at which a sector accumulates RUMs is called the RUM accumulation rate. When a sector issues a RUM (eg, on behalf of a base station or mobile device in the sector), the accumulated RUM associated with that sector is decremented. Thus, the RUM accumulation rate can at least partially affect the rate at which a sector sends out RUMs.

  In at least one aspect of the present disclosure, the accumulation of RUMs is determined for each sector. The rate at which a sector accumulates RUMs may be based on the performance metric of that sector compared to a similar performance metric of one or more neighboring sectors. The accumulation of RUMs can be established, increased, and / or decreased based on a comparison of sector performance metrics. It should be understood that establishing and / or adjusting the RUM accumulation rate described herein can be applied to either FL RUM or RL RUM, or both. Furthermore, performance metrics can be monitored over time to adjust / maintain RUM accumulation based on the latest changes in monitored metrics. Thus, the present disclosure provides for implementing fairness between sectors based on the performance of various sectors of the mobile AN.

  In at least one aspect, sector performance metrics can be collected on a backhaul network between base stations. In another aspect, these metrics can be collected at a designated base station and shared between various base stations, or can be centralized (eg, in a radio access network [RAN] Centralized components, mobile backend network components coupled to each of the various base stations, etc.). According to a further aspect, one or more ATs collect performance metrics from base stations in the wireless AN and forward the collected metrics to serving base stations associated with the AT. It is possible. For example, an AT can decode performance metrics over the air (OTA) from base station broadcast transmissions near the wireless AN (eg, when such broadcast transmissions have appropriate SNR characteristics at the AT). is there. The AT can then forward the performance metric information to the serving base station coupled to the AT. Alternatively, in some aspects, the AT retransmits and / or forwards broadcast transmissions to a serving base station that can decode performance metrics from the retransmitted / forwarded signals. Is possible.

  In one or more other aspects, the sector RUM accumulation rate is determined based on aggregate sector performance. For example, a wireless AT base station collects adjacent base station performance metric information from such a base station (eg, on a backhaul network) and / or from an AT served by a wireless AN base station. It is possible. The collected information can be aggregated at the base station (or, for example, in some cases, at the central controller of the wireless AN) to provide an aggregate performance metric for the set of base stations of the wireless AN. is there. The performance metric of an individual sector (or each sector of the wireless AN, for example) is then compared to the aggregated data to determine the extent of that individual sector's shortcomings compared to the aggregated data. Is possible. The degree of that drawback can be utilized to establish and / or update the RUM accumulation rate for the sector, if any. For example, the RUM accumulation rate can be increased, decreased, or maintained based on sector performance metrics compared to aggregated data. By aggregating adjacent sector data in individual sectors, the relative interference changes observed in individual sectors can be established.

  According to yet other aspects, the rate at which sectors issue RUMs, or the rate at which sectors associate RUMs with ATs within the sectors, may also be based on aggregate performance metrics. Thus, compared to sector aggregation, if a sector has an insufficient median data rate, the RUM accumulation rate and / or RUM issue rate for that sector may be increased. If, at a later point in time, the median data rate of the sector improves for aggregate sector data, the accumulation / issue rate can be maintained or reduced as needed. Accordingly, this disclosure provides controlled accumulation and / or issuance of RUMs based on sector performance, and adjusts sector performance by increasing / decreasing the rate at which RUMs are accumulated in various sectors A mechanism is further provided.

The performance metric (s) for sector (306A, 306B) is calculated and calculated from base station 306A, 306B serving sector (306A, 306B) or such base station 306A, 306B It can be obtained from a communicating mobile device 304. The performance metric data (s) is transmitted via a communication link that couples the RUM accumulator with base stations 306A, 306B and / or a radio link with mobile device 304. It can be transferred to the collector 308.

  The RUM accumulator 304 may further comprise a management module 310 that establishes a rate at which devices (304) in the sectors (306A, 306B) accumulate RUMs. Established RUM accumulation rate (s) is a comparison of performance metrics for a particular sector (eg, 306A) compared to similar performance metrics for at least one additional sector (eg, 306B). Or based on performance metric data aggregated from multiple sectors. As a more specific example, the median data transfer rate for sector A (306A) served by base station 306A may be transferred to data collector 308. Further, the median data transfer rate for sector B (306B) served by neighboring base station 306B may be transferred to data collector 308. The RUM accumulation rate for sector A and related devices (304) may be based at least in part on a comparison of the median data rate of sector A compared to the median data rate of sector B. In accordance with some aspects, the RUM accumulation rate is determined by the performance (s) of each sector (306A, 306B) based on, for example, another such comparison determined at periodic periods. It can be updated, such as after a threshold change is detected in the metric, or a combination thereof.

  Data collected by the data collector 308 is within the memory 312 (which may comprise any suitable form of electronic and / or magnetic storage media, such as, for example, a disk drive, optical disk, flash memory, random access memory, etc.) Can be stored. Further, the results of performance metric comparisons performed by management module 310 may be stored in memory 312 for reference. For example, when deciding whether to update a RUM accumulation rate determined based on a change in performance metric (s), the result or the previous RUM accumulation rate (s) is , Can be obtained from the memory 312. RUM accumulator 302 provides instructions regarding data stored in memory 312 (eg, data collection and data storage in memory, analysis of relationship between metric and sector, one sector and one for the process of RUM accumulator 302. A processor 314 configured to perform comparison metrics for one or more other sectors, determining a RUM accumulation rate based on such comparison, updating the RUM accumulation rate, and the like.

  It should be understood that any number of base stations 306 A, 306 B may be included in the radio access network (RAN) 306 of system 300. Base stations 306A, 306B are cellular transceivers, wireless fidelity (WiFi) transmitters, microwave frequency transmitters (e.g., worldwide interoperability for microwave access [WiMAX]). ]), Etc., may be included that are coupled to a common wireless mobile RAN site 306. Accordingly, various cellular technologies, mobile communication technologies, and similar access technologies can be included within 306 mobile RAN sites.

  FIG. 4 shows a block diagram of an exemplary RUM management device 402 in accordance with one or more aspects of the present disclosure. The device 402 may be coupled to a RAN centralized controller (eg, see the system controller 130 of FIG. 1 above), or one or more base stations (eg, above) of the RAN. 3 can be distributed across the base stations 306A, 306B of FIG. 3 or the backhaul network 506) of FIG. 5 below. The apparatus 402 obtains performance metrics for wireless communications provided by such base stations, aggregates the data, and determines and updates sector RUM accumulation rates based on the sector metrics compared to the aggregated metric data. It is possible. Thus, system 400 provides a fairness-based RUM accumulation technique that can determine the desired communication metric and optimize the overall RAN operation based on the changing communication metric level. .

  The RUM management device 402 may include an accumulator 406 that receives data via the communication interface 404 using RAN components (eg, base stations). The accumulator 406 is associated with the RAN sector based on a comparison of the sector performance metric with the data collector 410 that obtains performance metric data regarding the RAN sector and the performance metric of at least one other sector. A management module 412 for determining the RUM accumulation rate. Thus, the device 402 can provide a fairness-based sector RUM accumulation rate based on a desired metric for wireless communication. Thus, sectors that exhibit insufficient metrics can be given a higher RUM accumulation rate, resulting in more RUMs being issued to devices in insufficient sectors. Thus, sectors exhibiting a relatively strong metric can be given a lower RUM accumulation rate, resulting in fewer RUMs being issued to devices in strong sectors. Thus, by having more RUMs, insufficient metric sectors can more easily reduce the transmission power of neighboring interfering transmitters. Similarly, strong metric sectors have less ability to reduce the transmission power of adjacent transmitters. Such an arrangement provides significant benefits. First, devices that need to reduce the power of interfering transmissions are given a greater opportunity to do so. In addition, devices that only need to reduce the power of interfering transmissions have fewer opportunities to do so. If an insufficient sector is adjacent to a strong sector, the insufficient sector avoids significantly reducing its own signal power by the RUM issued for the strong sector, while at the same time transmitting power of the adjacent sector. It is important to be able to reduce

  The RUM management device 402 may further include a RUM control device 408. Controller 408 may establish a ratio for the device to issue accumulated RUMs based on inter-sector performance metrics. Further, the controller 408 can manage the RUM accumulation rate based on the changing sector performance metric, where the accumulation rate is one (1) of the sector compared to the metric of the adjacent sector. It can be updated based on changing disparities in performance metric (s).

  The controller 408 may comprise an implementation module 420 that establishes a rate at which devices in the sector can issue accumulated RUMs. This issue rate can be determined in addition to the accumulation rate determined by the RUM accumulator 406. Thus, a device can accumulate several RUMs over time, but may be limited in how quickly they can be utilized. Thus, if the performance metric for a device suddenly dramatically degrades, the device's ability to issue many accumulated RUMs in a short period of time, which can significantly degrade the performance of neighboring devices, is at least , Modulated by the number of RUMs accumulated for the sector serving the device. In at least one other aspect, RUM issuance may be further limited by a maximum RUM issuance rate. In yet another aspect, the RUM issue rate may depend on the degree of sector shortcomings. In at least one aspect, RUM issuance can be modulated by a combination of the aforementioned mechanisms or similar mechanisms.

  As discussed above, the RUM issue rate may be a predetermined ratio and / or to establish a cumulative rate (e.g., establish the degree of a sector's faults compared to other sectors). , A sector specific ratio established based on performance metric comparison similar to that determined by management module 412. In one or more aspects, this issue rate is modulated by an associated RUM accumulation rate (eg, of unit weight RUMs) for the sector serving the device (or in other aspects, the modulation is May include the weight of the weighted RUM). In such an aspect, the implementation module 420 can optionally configure terminals in the sector based on RUM accumulation rate, RUM issue rate, performance metric comparison, sector shortcomings, or a combination of these factors and / or similar factors. Can decide whether to send a RUM.

  The controller 408 may further comprise a priority adjustment module 418 capable of updating the RUM accumulation rate of the RAN sector. The ratio update may be based at least in part on a current performance metric comparison of such sectors compared to one or more adjacent sectors. The following example is provided to illustrate one aspect in which the RUM accumulation rate can be determined, but should not be construed as limiting. Rather, other methods for updating the RUM accumulation rate based on the performance metrics of multiple sectors of the RAN known by those skilled in the art or known to those skilled in the art by the context provided herein. The mechanism is included herein as part of the present disclosure.

For the following example, the following quantities are defined as follows:

At the end of the RUM ratio adaptation epoch (k) (eg, at the end of which the priority adjustment module 418 determines the updated RUM rate), the sector determines the r _i for time (k + 1). update to (or, for example, if appropriate, to leave without substantially changing the r _i) are possible. The updated r _i is stored in memory 416 and can be utilized by processor 414 to generate a RUM at a modified rate during time (k + 1). RUM accumulation rate adaptation is a fairness criterion that utilizes, in at least some embodiments, a comparison of sector performance compared to aggregate performance data for one or all other sectors j, including sector i. Can be based. The following algorithm provides a mechanism for updating r _i based on fairness between sectors.

Therefore, the median performance metric (eg, data transfer rate) m _i (k) of a sector is more than the median performance metric M _i (k) of a plurality of sectors (eg, all sectors j including sector i). If so, the RUM accumulation rate r _i of sector i may be increased by a positive amount. Conversely, if the median performance metric for sector i is less than or equal to the median performance metric for multiple sectors, the RUM accumulation rate for sector i may be reduced by a positive amount. In addition to the above, the RUM accumulation rate may be limited by a maximum accumulation rate and / or a minimum accumulation rate. The maximum rate can be determined to prevent faulty sectors from excessively degrading adjacent sectors. On the other hand, the minimum rate allows a sector to serve fewer users who are experiencing excessive interference, even if the sector as a whole is free of defects with respect to neighboring sectors. Further, the minimum accumulation rate and the maximum accumulation rate may be established based on the degree of a sector's shortcomings as compared to adjacent sectors, as described herein.

  In accordance with one or more additional aspects of the present disclosure, the priority adjustment module 418 may update the sector's RUM accumulation rate by a fixed amount or a variable amount. A certain amount can be predetermined based on various radio characteristics (eg, interference, multipath scattering) of the mobile RAN site. It should be noted that the radio characteristics can be updated at various times and used to modify that fixed amount. Variables can be used in terms of time for various factors that exist between one or more time periods that are close to a specific time period (eg, the state of a factor during time k can be used, k and / or the status of aggregated factors, etc. during one or more previous time periods k-2, k-1. Various factors may include the various radio characteristics discussed above with respect to the performance metric, a certain amount of sectors or one or more adjacent sectors, or a combination or similar combination thereof. Thus, the RUM accumulation rate can be adjusted by a varying amount. As an example, if a sector is significantly less than its neighbors, the corresponding RUM accumulation rate can be increased by a relatively large amount.

  According to one or more other aspects, the RUM management device 402 can further comprise a priority module 422 and a request parser 424. The priority module 422 can establish RUM weights issued by devices in the sector. This weight may be based at least in part on the current RUM accumulation rate for that sector. This weight is used to determine whether the RUM should be followed or ignored (eg, based on the performance metric (s) of the sector associated with the receiving transmitter). Can be used by the machine. The RUM request parser 424 can use the RUM accumulation rate to determine the priority of RUMs received by a particular transmitter (eg, base station, AT). RUM priority may be based at least in part on the RUM accumulation rate of the receiving transmitter, similar to the RUM weights discussed above. Thus, the RUM request parser 424 can determine whether the RUM should be followed by the receiving transmitter or ignored based on the priority.

  FIG. 5 shows a block diagram of a system 500 that provides RUM management to a mobile AN in accordance with aspects disclosed herein. System 500 may comprise a mobile device 502 coupled with a RAN base station 501A, 506B, 506C, 506D. In addition, these base stations are thereby coupled to a backhaul network 506 from which the base stations can exchange data. RUM accumulator 508 is coupled to the backhaul network. In one aspect, performance metric data for various sectors of the RAN is determined and shared among the base stations 506A, 506B, 506C, 506D via the backhaul network 506. In another aspect, performance metric data for various sectors can be uploaded from the base stations 506A, 506B, 506C, 506D to the RUM accumulator 508. According to yet other aspects, performance metrics can be determined from OTA messages received at mobile devices 502 in a sector. The mobile device can parse the OTA message to determine the performance metric of such message. Such metrics may then be provided to the RAN and base stations 506A, 506B, 506C, 506D and / or provided to the RUM accumulator 508 by such base stations 506A, 506B, 506C, 506D.

  The RUM accumulator 508 can determine the RUM accumulation rate for RAN sectors (506A, 506B, 506C, 506D) and distribute the RUM to those sectors for use by devices in the sector. . In another aspect, the RUM accumulation rate for each sector may be determined by base stations 506A, 506B, 506C, 506D associated with such sector. Once accumulated, the RUM can be delivered to the mobile device 502 as it accumulates.

  The RUM management module 504 coupled with the mobile device 502 can modulate the rate at which the RUM is issued to other devices (506A, 506B, 506C, 506D) in nearby sectors. The issuance rate for the mobile device 502 can determine how often the device 502 can send the accumulated RUM. The issuance rate may be determined based on a performance metric for wireless transmission within a sector, determined as described above. Further, the RUM cumulative rate and / or RUM issue rate may be updated based on the metric changes described herein. Accordingly, system 500 provides a fairness-based mechanism for accumulating RUMs and issuing RUMs utilizing sector performance metrics compared to one or more adjacent sectors.

  FIG. 6 illustrates a block diagram of a system 600 with a sample base station 602 that provides RUM cumulative management based on RAN sector performance metrics. In at least one aspect of the present disclosure, base station 602 can determine a performance metric based on radio transmissions specific to a sector of the RAN. Further, base station 602 can provide paging functionality to a mobile network for mobile devices 604 in a geographic area served by the network (see, eg, FIGS. 1 and 2). Base station 602 may continue until a response is received by the target mobile device, until an end paging instruction is received from the mobile network, or until an expiration timer maintained by base station 602 expires, or a combination thereof. It is possible to continue broadcasting the paging signal. According to certain aspects, the base station 602 can maintain a registration counter for the mobile device with respect to the tracking / location area served by the base station 602. Furthermore, the registration counter can be maintained even if the mobile device fails to respond to the paging event. Accordingly, the system 600 facilitates inter-system mobility by the paging device 604, independent of other systems (not shown) (eg, when the mobile device responds to other system pages). Maintain device registration despite paging response failure.

  Base station 602 (eg, access point,...) Receives a receiver 610 that receives signals from one or more mobile devices 604 via a plurality of receive antennas 606; And a transmitter 632 that transmits signals to one or more mobile devices 604 via transmit antenna (s) 608. Receiver 610 is capable of receiving information from receive antenna 606 and further includes a signal receiver (not shown) that receives uplink data transmitted by mobile device (s) 604. Can be prepared. In addition, receiver 610 is operatively associated with a demodulator 612 that demodulates received information. Demodulated symbols are analyzed by a processor 614 that also provides symbols to modulator 630 for transmission. The processor 614 is coupled to a memory 616 that stores information regarding the functions provided by the base station 602. In one example, the stored information may comprise a protocol for obtaining and / or determining performance metrics for wireless communications with mobile device 604. Specifically, the stored information determines the RUM accumulation rate as well as the RUM issue rate for such device 604 as a function of performance metrics compared to similar metrics associated with neighboring base station (s). Or it may have rules for updating.

  The processor 614 is further coupled to a data collector capable of obtaining performance metric information regarding the base station 602 and at least one neighboring base station (not shown). Information collected at data collector 618 may be stored in memory 616 for access by other components of base station 602 (612, 614, 620, 622, 624, 626, 628, 630). Is possible. The management module 620 may establish a rate at which mobile devices 604 in a sector serviced by the base station 602 (and, for example, communicatively coupled to the base station 602) accumulate RUMs. . This cumulative rate may be based on a comparison of performance metrics associated with base station 602 compared to at least one other neighboring base station, as described herein. The cumulative rate may be stored in memory 616 for reference by other components of base station 602 (612, 614, 620, 622, 624, 626, 628, 630).

  The priority adjustment module 622 can update the RUM accumulation rate based on subsequent performance metric base station 602 communications. Thus, if the median data transfer rate for a device 604 coupled to base station 602 decreases compared to the median data transfer rate for an adjacent sector, the priority adjustment module 602 increases the RUM accumulation rate for such device 604. Is possible. It should be understood that the foregoing example is merely one mechanism for updating the accumulation rate, and that the present disclosure should not be construed as limited to such example. Rather, other examples provided herein, examples known to those of ordinary skill in the art, or examples known to those of ordinary skill in the art from the context provided herein are incorporated into this disclosure.

  In addition to the foregoing description, the implementation module 624 can determine the rate at which the device 604 can send or issue accumulated RUMs. This issuance rate depends on various factors, including the sector's RUM cumulative rate, the number of devices 604 operating in the sector, one or more sector performance metrics, or a combination or similar combination thereof. Can be determined based on. According to some aspects, the implementation module 624 uses the rate at which a sector accumulates RUMs (eg, if the modulation can incorporate RUM weights, or if the RUMs can be of unit weight). Thus, it is possible to modulate the rate at which the device 604 issues RUMs. In at least other aspects, implementation module 624 may determine whether a terminal in a sector served by base station 602 sends a RUM based at least in part on the RUM accumulation rate and / or the RUM issue rate. Is possible.

  Base station 602 can further comprise a RUM request parser 626 that determines priorities of RUMs received by mobile device 604 from neighboring sectors. This priority may be established based on the RUM accumulation rate and the corresponding ratios and / or performance metrics of other sectors. In addition, the base station 602 may comprise a priority module 628 that adjusts the weight of RUMs issued or sent by devices 604 in the sector based at least in part on the RUM accumulation rate. Thus, neighboring devices that receive the RUM can determine whether to follow the issued RUM based at least in part on the weight. Optionally, if the RUM is of unit weight, all must be followed by such neighboring devices.

A mobile device 702 may be configured to wirelessly couple with one or more base stations 704 and associated mobile networks (not shown). Mobile device 702 may be further configured to obtain a performance metric of a neighboring base station and send the metric to serving base station 704 as described herein. .

  The mobile device 702 is received with at least one antenna 706 (eg, a transmission receiver or a group of such receivers with an input interface) that receives a signal (eg, a radio signal such as an OTA message). Receiver (s) 708 that perform typical operations (eg, filtering, amplification, down-conversion, etc.) on the received signals. According to at least some aspects, the processor (s) 712 analyzes the signals received from the demodulator (s) 710 to obtain a wireless performance metric for such signals. It is possible. In general, antenna 706 and transmitter 726 (collectively referred to as a transceiver) may be configured to facilitate wireless data exchange with base station (s) 704.

  Antenna 706 and receiver (s) 708 can demodulate the received symbols and provide the symbols to processor (s) 712 for evaluation ( It can also be combined with a demodulator 710 (one or more). In some aspects, the receiver 708 may receive an OTA transmission from the base station (704). In a particular example, the receiver 708 can obtain an OTA transmission with an adjacent base station performance metric from an adjacent base station (eg, as part of a broadcast signal from such base station). is there. This OTA message can be analyzed at mobile device 702 and / or forwarded to base station 704 for analysis. In addition, the receiver 708 can obtain a second OTA message from an adjacent base station with a RUM that requires the mobile device 702 to reduce power at the transmitter 726.

  The processor (s) 712 can control and / or reference one or more components (706, 708, 710, 714, 716, 724, 726) of the mobile device 702. Please note that. Further, the processor (s) 712 may include one or more modules, applications, engines, etc. (716, 718, 720, 722) with information or control regarding performing the functions of the mobile handset 702. ) Can be performed. For example, such functionality may include performing wireless communication with a remote device (704), receiving OTA messages, analyzing such messages, and wireless performance of wireless transmissions as described herein. This may include determining metrics, receiving and processing RUMs, and so on.

  Mobile handset 702 can further include a memory 714 operably coupled to processor (s) 712. Memory 714 may store data such as to be transmitted and received and instructions suitable for performing wireless communication with remote device (704). Further, the memory 716 may store modules, applications, engines, etc. (718, 720, 722) that are executed by the processor (s) above.

  In some aspects of this disclosure, the mobile device 702 determines a performance metric (eg, average data rate or median data rate, interference, SNR, etc.) of a radio signal received at the mobile device 702. An analysis module 716 may be provided. Further, the routing module 718 can wirelessly transmit the performance metric of one or more OTA messages obtained at the receiver 708 to the base station 704 serving the mobile device 702. It is. Based at least in part on the value of the performance metric, the serving base station 702 can send a message containing the RUM to the mobile device 704. This RUM can be issued to the device 702 for use by the mobile device 702 in managing nearby transmitter power, or to reduce power at the transmitter 726. It may be a similar such message sent to device 702.

In accordance with certain aspects of the present disclosure, the mobile device 702 can comprise a priority module 720 that identifies and processes a weighting factor for the received RUM. In addition, priority module 720 can determine a weighting factor for RUMs issued for use by mobile device 702. In any case, the weighting can be determined, at least in part, by the RUM accumulation rate associated with the sector serving mobile device 702. The arbitration component 722 may cause the processor 712 to comply with the DL RUM (eg, for RL data transmitted by the mobile device 702) based on a comparison of the DL RUM weighting factor and the sector performance metric. It is possible to order. The arbitration rules stored in memory 714 can determine when a DL RUM should be followed based on such comparison.
The foregoing system has been described with respect to interaction between several components, modules, and / or communication interfaces. Such systems and components / modules / interfaces may include those components or subcomponents specified herein, some of the specified components or subcomponents, and / or additional components. It should be understood that this can be included. For example, the system may include a RUM accumulator 302, a RUM controller 408, and a RUM management module 504, or different combinations of these components and other components. The subcomponents may be implemented as components that are communicatively coupled to other components, rather than included within the parent component. In addition, it should be noted that one or more components can be incorporated within a single component that provides aggregate functionality. For example, the data collector 308 can include a memory 312 to facilitate receiving wireless communication performance metrics and storing received metric information by a single component. And vice versa. These components are not described in detail herein, but may also interact with one or more other components known by those skilled in the art.

Can be intelligent and intelligent.

  In view of the exemplary system described above, methodologies that may be implemented in accordance with the disclosed subject matter will be better understood with reference to the flowcharts of FIGS. For ease of explanation, these methodologies are shown and described as a series of blocks, although some blocks are in a different order than the blocks shown and described herein, and / or It should be understood that claimed subject matter is not limited by the order of these blocks, as they may occur concurrently with different blocks. Moreover, not all illustrated blocks may be required to implement the methodology described below. In addition, the methodologies disclosed below and throughout the specification can be stored on a product to facilitate transporting and transferring such methodologies to a computer. Please understand further. The term product as used is intended to encompass a computer program accessible from any computer-readable device, carrier-related device, or storage medium.

  FIG. 8 shows a flowchart of an example methodology 800 that provides inter-sector fairness in reducing interference for mobile communications. At 802, method 800 can obtain performance metrics for at least two mobile base stations. This performance metric may relate to the quality of wireless communication associated with these two mobile base stations. As a specific example, this performance metric can be median data rate, average data rate, signal interference, SNR, guaranteed percentage of guaranteed bit rate, or a similar metric of a radio signal, or a combination thereof Can be provided.

  In one or more aspects, these at least two mobile base stations may be adjacent base stations of the mobile RAN site. In such a situation, the base station radio transmissions can often interfere with each other at the receiving device. The performance metric of such a signal can be determined at the receiving device and transmitted back to the base station. In another aspect, this performance metric can be obtained from an uplink signal received at a base station from a wireless device (eg, these metrics are specified in the uplink signal). Or the uplink signal itself can be analyzed to determine the performance metric of such signal). Performance metric information may be shared between base stations, aggregated at a common control device, and / or shared with mobile devices for further analysis.

  At 804, method 800 can determine a RUM accumulation rate for devices in a sector of a mobile RAN site. This ratio may be based at least in part on a comparison of performance metrics of at least two base stations. As a specific example to illustrate the foregoing description, the average data rate of a sector can be compared to the average data rate of adjacent sector (s). The RUM accumulation rate can then be established based on the comparison. In one particular aspect, performance metric data for all sectors can be aggregated to form aggregate sector performance metric data. The RUM accumulation rate for each sector may be based on a comparison of the performance metric for each sector with aggregate sector performance metric data. Accordingly, method 800 provides an algorithm for establishing RUM accumulation based on wireless communication performance relationships between sectors of a mobile RAN site. With such an algorithm, the possibility of improving sector performance at the expense of poorly executing sectors can be reduced, allowing increased reliability for mobile communications.

  FIG. 9 shows a flow diagram of an example methodology 900 that can manage the RUM accumulation rate for a sector at that site to provide inter-sector fairness for the mobile RAN site. At 902, method 900 can obtain performance metrics for at least two mobile base stations. At 904, method 900 can determine a RUM accumulation rate for a sector of a mobile RAN site served by each of those at least two base stations. At 906, method 900 can determine a RUM issue rate for devices in each sector based at least in part on the RUM accumulation rate. Thus, the frequency with which a particular device (or, for example, an aggregation of devices) can issue a RUM can be determined using its cumulative rate. Other factors that determine issuance rates include the number of devices in a sector, performance metrics associated with a particular device compared to other devices in the sector, and the type of call that the particular device is involved in (eg, service High quality calls can be given higher issuance rates to maintain the performance of such calls, and quality is relatively insignificant for low quality services. Thus, a low issuance rate can be given, etc.) or a combination thereof.

  At 908, method 900 can obtain performance metric changes. For example, performance metrics can be reevaluated at a later time. As a specific example, performance metrics may be reevaluated periodically. The current performance metric (or a change in the current metric compared to the previous metric, for example) can be utilized to reevaluate the RUM accumulation rate. At 910, method 900 can update the cumulative rate of sectors at the mobile RAN site based on a comparison of sector performance with an aggregate sector performance metric. Thus, if the sector performance metric is lower than the aggregate performance metric (or less than the aggregate performance metric, for example by a threshold amount), the RUM accumulation rate for such sector may be increased. If the sector performance metric is greater than the aggregate performance metric (or greater than, for example, the aggregate performance metric plus a threshold amount), the sector's RUM accumulation rate may be reduced. If the sector performance metric is substantially equal to the aggregate performance metric, the RUM accumulation rate can be increased, decreased, or left unchanged. In addition to the above description, sector performance metric changes are determined (eg, based on previous RUM accumulation rate, mobile RAN site radio conditions, mobile RAN site time averaged statistics, etc. A) based on a certain amount, or at least in part by a RUM accumulation rate, a difference in performance metric of that sector compared to at least one neighboring sector (eg, an aggregate performance sector), or a combination thereof It can be based on the determined variable.

  At 912, method 900 can establish sector priority based on a cumulative rate. This sector priority can be utilized to determine whether the RUM accumulation rate received at the device in the sector should be followed by the receiving device. This priority may be based at least in part on the sector's RUM accumulation rate. Alternatively or additionally, this priority may be based on the weight of the received RUM.

  FIG. 11 illustrates a block diagram of an example system 1100 that can facilitate wireless communication in accordance with certain aspects disclosed herein. On the downlink, at an access point 1105, a transmit (TX) data processor 1110 receives, formats, encodes, interleaves, and modulates (ie, symbol maps) traffic data to provide modulation symbols (“data symbols ")I will provide a. A symbol modulator 1115 receives and processes the data symbols and pilot symbols and provides a symbol stream. A symbol modulator 1120 multiplexes data symbols and pilot symbols and provides them to a transmitter unit (TMTR) 1120. Each transmit symbol may be a data symbol, a pilot symbol, or a signal value of zero. The pilot symbols can be sent continuously in each symbol period. Pilot symbols can be frequency division multiplexed (FDM), orthogonal frequency division multiplexed (OFDM), time division multiplexed (TDM), code division multiplexed (CDM). Or a suitable combination thereof, or a combination of similar modulation and / or transmission techniques may be performed.

  The TMTR 1120 receives the symbol stream and converts it to one or more analog signals to further adjust (eg, amplify,) the analog signal to generate a downlink signal suitable for transmission over the wireless channel. Filtering and frequency up-conversion). The downlink signal is then transmitted to the terminal via antenna 1125. At terminal 1130, antenna 1135 receives the downlink signal and provides the received signal to a receiver unit (RCVR) 1140. Receiver unit 1140 conditions (eg, filters, amplifies, and frequency downconverts) the received signal and digitizes the conditioned signal to obtain samples. A symbol demodulator 1145 demodulates received pilot symbols and provides them to a processor 1150 for channel estimation. Symbol demodulator 1145 further receives a frequency response estimate for the downlink from processor 1150 and performs data demodulation on the received data symbol to obtain a data symbol estimate (which is an estimate of the transmitted data symbol). Run to provide data symbol estimates to an RX data processor 1155 that demodulates (ie, symbol demaps), deinterleaves, and decodes the data symbol estimates to recover the transmitted traffic data. The processing by symbol demodulator 1145 and RX data processor 1155 is complementary to the processing by symbol modulator 1115 and TX data processor 1110 at access point 1105, respectively.

  On the uplink, a TX data processor 1160 processes the traffic data and provides data symbols. A symbol modulator 1165 receives the data symbols, multiplexes these pilot symbols with the pilot symbols, performs modulation, and provides a stream of symbols. Transmitter unit 1170 then receives the symbol stream and processes the symbol stream to generate an uplink signal that is transmitted by antenna 1135 to access point 1105. In particular, the uplink signal can comply with SC-FDMA requirements and can include a frequency hopping mechanism as described herein.

  At access point 1105, the uplink signal from terminal 1130 is received by antenna 1125 and processed by receiver unit 1175 to obtain samples. A symbol demodulator 1180 then processes these samples and provides received pilot symbols and data symbol estimates for the uplink. RX data processor 1185 processes the data symbol estimates to recover the traffic data transmitted by terminal 1130. A processor 1190 performs channel estimation for each active terminal transmitting on the uplink. Multiple terminals may transmit pilots simultaneously on the uplink on their respective assigned set of pilot subbands, where the pilot subband sets may be interlaced.

  Processors 1190 and 1150 command (eg, control, coordinate, manage, etc.) operation at access point 1105 and terminal 1130, respectively. Respective processors 1190 and 1150 can be associated with memory units (not shown) that store program codes and data. Processors 1190 and 1150 can also perform operations to derive frequency response estimates and impulse response estimates for the uplink and downlink, respectively.

  For multiple access systems (eg, SC-FDMA, FDMA, OFDMA, CDMA, TDMA, etc.), multiple terminals can transmit simultaneously on the uplink. For such a system, the pilot subband can be shared between different terminals. Channel estimation techniques may be used when the pilot subbands for each terminal span the entire operating band (possibly except for the band edges). Such a pilot subband structure would be desirable to obtain frequency diversity for each terminal. The techniques described herein may be implemented by various means. For example, these techniques can be implemented in hardware, software, or a combination thereof. For hardware implementations that can be digital, analog, or both digital and analog, the processing unit used for channel estimation is one or more application specific integrated circuits (ASICs), digital signal processors ( DSP), digital signal processing device (DSPD), programmable logic element (PLD), field programmable gate array (FPGA), processor, controller, microcontroller, microprocessor, to perform the functions described herein Can be implemented in other electronic units designed in the above, or combinations thereof. In the case of software, implementation may be via modules (eg, procedures, functions, etc.) that perform the functions described herein. Software code may be stored in a memory unit and executed by processors 1190 and 1150.

System 1200 comprises a module 1202 for obtaining a performance metric for a sector of a mobile RAN site. Module 1202 may further obtain a performance metric for at least one adjacent sector. In at least one aspect, this performance metric may be aggregated into a single aggregated metric for mobile RAN site wireless communications. System 1200 can further comprise a module 1204 that establishes a rate at which devices in a sector accumulate RUMs. Module 1204 may establish the ratio based at least in part on a comparison of the performance rate for the sector and the performance rate (s) of the adjacent sector (s). In one particular aspect, module 1204 can establish this ratio based on the performance rate for the sector and the aggregate performance rate for the sector of the mobile RAN site.

  System 1300 can comprise a module 1302 for obtaining a wireless OTA message. This module can obtain a first OTA message with a performance metric of the sector of the mobile AN. Module 1302 may further obtain a second OTA message with a RUM. The first OTA message and / or the second OTA message and information related thereto may be maintained in a module 1306 for storing data. In addition to the foregoing description, system 1300 can comprise a module 1304 for forwarding an OTA message to a serving base station. Module 1304 may forward, for example, the first OTA message, or at least the performance metric, to the serving base station. In one particular aspect, a response to the first OTA message from the serving base station can determine whether the RUM should be followed by the system 1300. Such a determination may be implemented by a module 1308 for executing process instructions, where such instructions are based at least in part on a sector performance metric, a RUM weight, or a combination of both. .
