## Title
Adjustment of transmit power parameter

## Abstract

Adjustment of a downlink transmit power parameter, such as a ceiling level, is disclosed. Signal-to-noise type information and committed power information can be employed to determine the ceiling level adjustment. A ceiling level can be a predetermined cap on transmission power for downlink channels between a user equipment and a base station. Where there is sufficient headroom in total transmission power and a power level greater than the predetermined ceiling can be effective, the ceiling can be adjusted to greater values than the predetermined value. Where total transmission power is more committed, ceiling adjustment can be prevented. Further, where there is no adequate benefit from increasing the ceiling, the adjustment of the ceiling can be prevented. While some instances can result in optimized transmission levels below the ceiling, instances can also be accommodated where the ceiling is to be increased.

TECHNICAL FIELD
The disclosed subject matter relates to adjustment of a base station parameter, e.g., the adjustment of a downlink transmission power level parameter for a base station.
BACKGROUND
By way of brief background, the air interface between mobile devices and base stations can be associated with degradation of communication signals transmitted over the air interface. Degradation can be associated with signal attenuation, signal scattering, signal interferers, etc. As an example, signal attenuation can occur when a transmission signal passes between a mobile phone located in a concrete and steel building and a NodeB outside the building due to the signal being attenuated by the building materials. As a further example, signal degradation can occur when noise increases, such as other mobile devices transmitting nearby, making it more difficult to retrieve information carried by the transmitted signal between a mobile device and a base station. Degradation can also increase with the distance between a mobile device and a base station.

DETAILED DESCRIPTION
The subject disclosure is 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 the subject disclosure. It may be evident, however, that the subject disclosure may 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 the subject disclosure.
As mentioned, degradation can occur with respect to communication signals of the over the air interface. In this regard, mobile telecommunications providers, in some cases, can adjust the power level of transmissions between the mobile device and the base station to compensate for degradation of the signal. As an example, mobile devices in a handover can form a new communicative link with a base station at a predetermined power level that is sufficiently high to establish an effective link as a matter of probability for most air interface conditions. The transmit power of this link can then be adjusted to a lower and/or more efficient power level based on feedback information reflective of the actual air interface conditions. As such, where the mobile device is close to the base station and the air interface conditions are not suffering from amounts of degradation of communication signals, e.g., determined to satisfy a condition of defined “largeness”, the power level can generally be decreased below the initial formation power level to increase efficiency given the improved conditions. Further, where the mobile device is far from the base station and the air interface conditions are poor, e.g., determined to satisfy a condition of defined “poorness”, the power level can be decreased more moderately, if at all, to maintain the link in the poor conditions.
Accordingly, as described herein in various embodiments, instantiating and maintaining communicative links between mobile devices and base stations can include adaptation of an operating transmit power level for the uplink and downlink for the mobile device and the base station. Generally, environmental conditions of an air interface between a mobile device and a base station can impact the quality of the communication link. As such, where link quality is considered satisfactory, e.g., determined to satisfy a defined condition, transmit power can typically be reduced. In such a case, a mobile device consumes less power at lower transmit power levels, and reduced transmit power levels also generally reduce the significance of the transmitter as an interferer, e.g., lower transmission power levels correspond to a less noisy environment for other communicative links, etc. Conversely, where link quality is considered poor, transmit power levels generally can be increased to improve link performance. An increase in transmit power levels can increase signal strength relative to other environmental noise and allow a link to operate at a higher quality. However, increased transmit power levels for a link are associated with increased power consumption and increased effect as an interferer for other links in the air interface. Moreover, a base station, generally speaking, shares a finite amount of power for all communicative links between the base station and a plurality of mobile devices linked over the air interface to the base station. As such, increasing a transmit power level for a downlink between the base station and a mobile device reduces the amount of power available to other links between mobile devices and the base station.
As an example, base stations can designate a defined limit for a channel transmit power level that can be based on the total transmit power available to the base station. This defined limit is analogous to an adjustable ‘ceiling’, as used herein throughout. Ceiling power can, in some embodiments, be considered the same as, or similar to, maximum power per radio link, e.g., the maximum transmit power for a downlink channel between a base station and a mobile device. For instance, a ceiling transmit power level indicates a defined limit on allowable transmit power level when adjusting a transmit power level, e.g., a maximum allowable transmit power level or an upper limit to the allowable transmit power level. As such, the ceiling power level can be approximated as an immutable level, or set to a value within a defined range that approximates the ceiling power level. As an example, a universal mobile telecommunications system base station, e.g., NodeB, typically has a maximum output power of about 43 dBm or 46 dBm (20 or 40 watts), where ‘dBm’ is an abbreviation for the power ratio in decibels (dB) of the measured power, referenced to one milliwatt. A ‘loading factor’ can then be applied, for example, 50% or 75% of maximum output power. A defined maximum number of users can be determined, and can be based on the chip rate, an energy-to-noise value, anticipated interference factors, data rate, and the loading factor. The maximum number of users can also be determined by spreading-code space limitations. The per channel transmit power ceiling can be determined from the maximum output power, the loading factor, and the maximum number of users as will be appreciated by one of skill in the art. Transmission links are then generally not allowed to consume more power than that capped by the ceiling power level.
While some instances result in downlink transmission power levels that are much lower than the ceiling level, there can be circumstances where exceeding the instant ceiling power level can be beneficial, e.g., automatically adjusting the ceiling power level up can provide higher ceiling power levels under certain conditions. As an example, where there are relatively few downlinks between a base station and served mobile devices, representative of low utilization of available transmission power, and a served mobile device is in an environment associated with unusually high signal attenuation, incrementally increasing the per channel transmit ceiling level can facilitate downlink transmissions at higher power levels that can be sufficiently elevated to allow maintenance of the downlink connection to the served mobile device. This can serve to allow the downlink to be established and maintained in poor air interface conditions that would otherwise be unlikely to facilitate the downlink without ceiling power level adjustment. In an aspect, where there is low utilization of available power, the imposed ceiling may not reflect the actual usage of the air interface and dynamically adjusting the ceiling can allow for increasing actual transmit levels to facilitate downlink service to a mobile device that would otherwise be unlikely.
Automatically adjusting the downlink transmit ceiling level can be based on information relating to transmission power commitment. Transmission power commitment information can be related to the utilization of available transmit power, e.g., how much of the available transmit power is committed to established downlinks. As an example, a 20 W NodeB with a 50% loading factor can be associated with 10 W of available transmit power. Where, for example, 9 W of the 10 W are committed, e.g., associated with operable downlinks, it can be undesirable to allow an increase of the transmit power ceiling for a channel as it could result in total committed transmit power consumption exceeding the 10 W available.
Transmission power commit information can include information relating to the overall available transmit power, the loading factor, the available transmit power, the allocated transmit power, etc. This information can be employed to determine commitment information, such as, a ratio of committed to overall available transmit power. Automatic adjustment of a downlink transmit power ceiling level can then be based, in part, on the commitment information. As an example, adjustment of the ceiling can be permissible where less than 50% of available power is committed. As a further example, adjustment of the ceiling can be restricted where the ratio of available to committed power is greater than unity. As yet another example, decrementing the downlink transmit power ceiling can be enforced where the percentage of committed power exceeds 65%, e.g., where there is more than 65% committed power, any elevated ceiling levels can be actively reduced, such as to predefined ceiling levels. It is noted that numerous other rules relating to adjustment of the ceiling can be related to nearly any aspect of transmission commitment information and are considered within the scope of the presently disclosed subject matter despite not being explicitly recited for the sake of clarity and brevity. In an aspect, the ceiling can be adjusted where there is a need and where there is enough power available to fill that need.
In an embodiment, a system can include a processor and memory. The processor can facilitate the execution of instructions stored on the memory. The execution of the instructions can cause the processor to receive information related to signal conditions and noise conditions for a wireless communications channel associated with a base station device and a user equipment. The processor can further be caused to receive information related to power commitment conditions for the base station device. The processor can then determine an adjustment to a ceiling value related to a predetermined limit of a transmission power level for the wireless communications channel and facilitating access to that adjustment value.
In another embodiment, a method can include receiving, by a system including a processor, information related to signal conditions and noise conditions for a wireless downlink communications channel associated with a base station device and a user equipment. The method can also include receiving information related to power commitment conditions for the base station device. The method can allow for determining an adjustment to a ceiling value related to a predefined maximum transmission power level for the wireless downlink communications channel and facilitating access to said adjustment value by the base station device.
In a further embodiment, a computer-readable storage medium can include instructions that cause a processor to perform operations comprising receiving, at a base station device from a mobile device, information related to signal conditions and noise conditions for a wireless communications channel associated with the base station device and the mobile device. The operations can further include, receiving, at the base station device, information related to power commitment conditions for the base station device. The operations can then determine, at the base station device, an adjustment to a ceiling value related to a predetermined limit of a transmission power level for the wireless communications channel and facilitate access to the adjustment value by a component of the base station device associated with setting the transmission power level.
To the accomplishment of the foregoing and related ends, the disclosed subject matter, then, comprises one or more of the features hereinafter more fully described. The following description and the annexed drawings set forth in detail certain illustrative aspects of the subject matter. However, these aspects are indicative of but a few of the various ways in which the principles of the subject matter can be employed. Other aspects, advantages and novel features of the disclosed subject matter will become apparent from the following detailed description when considered in conjunction with the provided drawings.
FIG. 1 is an illustration of a system 100, which facilitates adjustment of a transmit power parameter in accordance with aspects of the subject disclosure. System 100 can include power ceiling determination component 110 that can automatically determine adjustment of a downlink transmit ceiling level. Power ceiling determination component 110 can generate power ceiling adjustment information based on the determined adjustment to be made to a downlink transmit ceiling. In an aspect, this determination can be based, at least in part, on a determined performance of the downlink and a determined level of uncommitted power that can facilitate an adjustment of a downlink transmit power ceiling.
Power ceiling determination component 110 can receive signal-to-noise information 170. Signal-to-noise information 170 can include carrier-to-noise ratio information, signal-to-noise ratio information, Eb/N0 information (e.g., energy per bit relative to noise power spectral density), signal-to-interference information, Es/N0 information (e.g., energy per symbol relative to noise power spectral density), C/N0 information (e.g., carrier to receiver noise density), etc. Signal-to-noise information 170 can be employed to determine the performance of a signal, for example, signal-to-noise information 170 can facilitate determining the performance of a downlink between a base station and mobile device. Signal-to-noise information 170 can include metrics that, for example, can indicate that increasing the transmission power of a downlink transmission can improve the signal quality relative to signal interference.
Power ceiling determination component 110 can further receive transmission power commitment information 180. Transmission power commitment information 180 can include information related to base station utilization of available power for downlink transmissions. In an aspect, transmission power commitment information 180 can include metrics for total available power, total link budget power, total downlink transmit power, committed power, committed link budget power, committed downlink transmit power, available power, available link budget power, available downlink transmit power, etc. Transmission power commitment information 180 can facilitate determining a difference between total or available downlink transmit power and committed downlink transmit power. This difference can be referred to by the term ‘headroom’, as used herein throughout, referring generally to an amount still available before attaining a limit with respect to an amount consumed. In an embodiment, downlink transmit power headroom can represent the amount of uncommitted downlink transmit power available for a base station. As such, transmission power commitment information 180 can facilitate determining downlink transmit power headroom that can be committed by downlink channels allowed to exceed a predetermined ceiling power level.
Power ceiling determination component 110 can be communicatively coupled to power ceiling adjustment component 190. Power ceiling determination component 190 can facilitate adjustment of a downlink channel transmit ceiling level. Power ceiling determination component 190 can automatically adjust the downlink transmit ceiling level in response to a receiving power ceiling adjustment information.
As an example, power ceiling determination component 110 can determine that an increase in transmit power on a downlink channel has a sufficiently high probability of improving downlink performance. The power ceiling determination component 110 can further determine that there is sufficient power headroom to facilitate exceeding the predefined downlink power ceiling level. In response to these determinations, power ceiling determination component 110 can generate power ceiling adjustment information. This power ceiling adjustment information can be received, for example, at power ceiling adjustment component 190. In response to receiving power ceiling adjustment information, power ceiling adjustment component 190 can automatically adjust the power ceiling of the downlink. Automatically adjusting the power ceiling of the downlink channel can allow the downlink to transmit at a higher power level. Where the downlink channel does increase transmit power in response to operating with an elevated power ceiling, the increase in transmit power can be reflected in an increase in committed power, an increase in interference as a result of the higher transmit power (e.g., as an interferer), an increase in the performance of the downlink channel (e.g., improved carrier-to-noise ratio, Eb/N0, etc.) due to the higher transmit power, etc. Where these changes impact signal-to-noise information 170 or transmission power commitment information 180, these changes can be reflected in future automatic determinations for adjusting the power ceiling of a downlink channel.
In an aspect, system 100 can be embodied in a base station or other radio access network component. In a further aspect, system 100 can be distributed between mobile devices and radio access network components. As an example, power ceiling determination component 110 can be part of a NodeB, part of a user equipment (UE), part of a deployed sensor, part of a personal access point, etc. As another example, power ceiling adjustment component 190 can be part of a NodeB, part of a radio network controller, etc.
FIG. 2 is a depiction of a system 200 that can facilitate generation of transmit power parameter adjustment information at a mobile device in accordance with aspects of the subject disclosure. System 200 can include mobile device 202. Mobile device can 202 can include a smartphone, a cell phone, a laptop computer, a tablet computer, a navigation system, or any other mobile device. Further, mobile device 202 can be embodied in a mobile device employed in a non-mobile manner, such as a laptop computer housed in a fixed kiosk, a tablet computer affixed to a table, etc.
System 200 can include power ceiling determination component 210 that can automatically determine adjustment of a downlink transmit ceiling level. Power ceiling determination component 210 can generate power ceiling adjustment information based on a determined adjustment to be made to a downlink transmit ceiling. In an aspect, this determination can be based, at least in part, on a determined performance of the downlink and a determined level of uncommitted power that can facilitate an adjustment of a downlink transmit power ceiling.
Power ceiling determination component 210 can be communicatively coupled to signal-to-noise analysis component 230. Signal-to-noise analysis component 230 can determine signal-to-noise information, such as signal-to-noise information 170. Signal-to-noise information can be employed to determine the performance of a signal, for example, signal-to-noise information can facilitate determining the performance of a downlink between a base station and mobile device. Signal-to-noise information can include metrics that, for example, can indicate that increasing the transmission power of a downlink transmission can improve the signal quality relative to signal interference. Signal-to-noise information can be based on an analysis of relevant channel information.
Signal-to-noise analysis component 230 can receive occupied channel information 272. Occupied channel information 272 can include signal strength, quality metrics, etc., for an occupied channel, e.g., a downlink channel between a base station and mobile device 202. Signal-to-noise analysis component 230 can further receive pilot channel information 274. Pilot channel information 274 can include pilot signal strength, quality metrics, etc., for a pilot channel received from the base station by mobile device 202. In an aspect, pilot channel information can be associated with a common pilot channel, such as CPICH, which is a common pilot channel familiar to those of ordinary skill in the art. The common pilot channel can be a downlink channel broadcast by a NodeB at a constant power and with a known bit sequence. The downlink power level is generally between 5% and 15% of total transmit power for a Node B. Typically, common pilot channel power is set at 10% of the typical total transmit power. Thus where a NodeB typically has a total transmit power of 43 dBm, the common pilot channel can have a transmit power around 33 dBm. The use of a pilot channel allows for relative measurement, such as phase and power estimations, among other functions. Analysis of occupied channel information 272 relative to pilot channel information 274 can facilitate determination of signal-to-noise information.
Power ceiling determination component 210 can further be communicatively coupled to committed power analysis component 240. Committed power analysis component 240 can determine transmission power commitment information, such as transmission power commitment information 180. Transmission power commitment information can be employed to determine base station utilization of available power for downlink transmissions. Committed power analysis component 240 can receive power available information 282 that can include information related to total available power, available link budget power, available downlink transmit power, etc. Committed power analysis component 240 can further receive power committed information 284 that can include information related to total committed power, committed link budget power, committed downlink transmit power, etc. Committed power analysis component 240 can facilitate determining how much headroom remains in the downlink transmit power that can be shifted to downlink channels allowed to exceed a predetermined ceiling power level.
Power ceiling determination component 210 can determine that an increase in transmit power on a downlink channel has a sufficiently high probability of improving downlink performance. The power ceiling determination component 210 can further determine that there is sufficient power headroom to facilitate exceeding the predefined downlink power ceiling level. In response to these determinations, Power ceiling determination component 210 can generate power ceiling adjustment information 260. Power ceiling adjustment information 260 can be made available to other systems and components. In an aspect, power ceiling adjustment information 260 can be received, for example, at power ceiling adjustment component 190. Where power ceiling adjustment component 190 is communicatively coupled to a base station, it can facilitate automatically adjusting the power ceiling of a downlink in response to receiving power ceiling adjustment information 260. Automatically adjusting the power ceiling of the downlink channel can allow the downlink to transmit at a higher power level than would be allowed under conventional static power ceiling designation.
FIG. 3 illustrates a system 300 that facilitates generation of transmit power parameter adjustment information at a base station device in accordance with aspects of the subject disclosure. System 300 can include base station device 304. Base station device can 304 can include a NodeB, eNodeB, a wireless access point, a personal base station, etc., or components thereof. Further, base station device 304 can be embodied in a femtocell, picocell, microcell, etc.
System 300 can include power ceiling determination component 310 that can automatically determine adjustment of a downlink transmit ceiling level. Power ceiling determination component 310 can generate power ceiling adjustment information based on a determined adjustment to be made to a downlink transmit ceiling. In an aspect, this determination can be based, at least in part, on a determined performance of the downlink and a determined level of uncommitted power that can facilitate an adjustment of a downlink transmit power ceiling. Power ceiling determination component 310 can be communicatively coupled to signal-to-noise analysis component 330. Signal-to-noise analysis component 330 can determine signal-to-noise information, such as signal-to-noise information 170. Signal-to-noise information can be employed to determine the performance of a signal, for example, signal-to-noise information can facilitate determining the performance of a downlink between base station 304 and a mobile device. Signal-to-noise information can include metrics that, for example, can indicate that increasing the transmission power of a downlink transmission can improve the signal quality relative to signal interference. Signal-to-noise information can be based on an analysis of relevant channel information.
Signal-to-noise analysis component 330 can receive occupied channel information 372. Occupied channel information 372 can include signal strength, quality metrics, etc., for an occupied channel, e.g., a downlink channel between base station 304 and a mobile device. Signal-to-noise analysis component 330 can further receive pilot channel information 374. Pilot channel information 374 can include pilot signal strength, quality metrics, etc., for a pilot channel of base station 304, as received by a mobile device. Analysis of occupied channel information 372 relative to pilot channel information 374 can facilitate determination of signal-to-noise information. In an embodiment, signal-to-noise analysis component 330 can receive signal-to-noise information directly from a mobile device (not illustrated) rather than raw information to determine signal-to-noise information at signal-to-noise analysis component 330 (as illustrated).
Power ceiling determination component 310 can further receive power available information 382 that can include information related to total available power, available link budget power, available downlink transmit power, etc. Power ceiling determination component 310 can further receive power committed information 384 that can include information related to total committed power, committed link budget power, committed downlink transmit power, etc. Power ceiling determination component 310 can determine transmission power commitment information based, at least in part, on power available information 382 and power committed information 384. In an aspect, power ceiling determination component 310 can facilitate determining how much headroom remains in the downlink transmit power that can be shifted to downlink channels allowed to exceed a predetermined ceiling power level. In an embodiment, power ceiling determination component 310 can receive transmission power commitment information directly (not illustrated) rather than raw information to determine transmission power commitment information (as illustrated).
Power ceiling determination component 310 can therefore receive signal-to-noise information, e.g., from signal-to-noise analysis component 330, and can determine (or receive) transmission power commitment information, and can employ this information to determine automatic adjustment of transmit power on a downlink channel. For example, this can include increasing the transmit power ceiling where there is a sufficiently high probability of improving downlink performance with higher transmit power levels that would be permitted with an increased ceiling. The power ceiling determination component 310 can further determine that there is sufficient power headroom to facilitate exceeding the predefined downlink power ceiling level.
Power ceiling determination component 310 can generate power ceiling adjustment information 360. Power ceiling adjustment information 360 can be made available to other systems and components. In an aspect, power ceiling adjustment information 360 can be received, for example, at power ceiling adjustment component 190. Where power ceiling adjustment component 190 is communicatively coupled to a base station, it can facilitate automatically adjusting the power ceiling of a downlink in response to receiving power ceiling adjustment information 360. Automatically adjusting the power ceiling of the downlink channel can allow the downlink to transmit at a higher power level than would be allowed under conventional static power ceiling designation.

Power ceiling determination component 510 can further determine transmission power commitment information, such as transmission power commitment information 180. Transmission power commitment information can be employed to determine base station utilization of available power for downlink transmissions. Power ceiling determination component 510 can receive power available information 582 that can include information related to total available power, available link budget power, available downlink transmit power, etc. Power ceiling determination component 510 can further receive power committed information 584 that can include information related to total committed power, committed link budget power, committed downlink transmit power, etc. Power ceiling determination component 510 can facilitate determining how much headroom remains in the downlink transmit power that can be shifted to downlink channels allowed to exceed a predetermined ceiling power level. In an embodiment, power ceiling determination component 510 can receive transmission power commitment information directly (not illustrated) rather than raw information to determine transmission power commitment information (as illustrated).
Power ceiling determination component 510 can be further communicatively coupled to power optimization component 550, which can also receive signal-to-noise information or signal-to-noise information precursors including occupied channel information 572 and pilot channel information 574. Power optimization component 550 can determine one or more target downlink power levels associated with optimized performance of the channel and mobile device 502. In an aspect, optimizations can include aspects of reducing power consumption, improving battery performance, improving information carrying capacity on the channel, etc. In some embodiments, power optimization component 550 can include well known optimization techniques to generate a target downlink transmit power level. This target downlink transmit power level can be made available to power ceiling determination component 510. As an example, power optimization component 550 can determine a target downlink transmit power level to maintain the signal-to-interference ratio of the service in use on the downlink channel. Mobile device can receive a quality-of-service (QoS) parameter, fixed by a network service provider, for the signal-to-interference target associated with the service used by mobile device 502. If the received power exceeds the target, mobile device 502 can send a request to the UE to decrease the transmitted power level. If on the contrary, the received power is not enough, mobile device 502 can send a request to increase the transmitted power, in order to arrive at the desired QoS. However, where the increase in the transmitted power level exceeds the ceiling in a conventional system, the power level increase request would be refused and the QoS would not be improved. In contrast to conventional systems, this request to exceed the ceiling can be passed from power optimization component 550 to power ceiling determination component 510.
Power ceiling determination component 510 can determine that an increase in transmit power on a downlink channel has a sufficiently high probability of improving downlink performance. This can be based, at least in part, on information received from power optimization component 550. The power ceiling determination component 510 can further determine that there is sufficient power headroom to facilitate exceeding the predefined downlink power ceiling level. In response to these determinations, power ceiling determination component 510 can generate power ceiling adjustment information 560. Power ceiling adjustment information 560 can be made available to other systems and components. In an aspect, power ceiling adjustment information 560 can be received, for example, at power ceiling adjustment component 190. Where power ceiling adjustment component 190 is communicatively coupled to a base station, it can facilitate automatically adjusting the power ceiling of a downlink in response to receiving power ceiling adjustment information 560. Automatically adjusting the power ceiling of the downlink channel can allow the downlink to transmit at a higher power level than would be allowed under conventional static power ceiling designation.

FIG. 7 illustrates aspects of method 600 facilitating adjusting a transmit power parameter in accordance with aspects of the subject disclosure. At 610, method 600 can include receiving instant power ceiling information.

In an aspect, transmission power commitment information can include metrics for total available power, total link budget power, total downlink transmit power, committed power, committed link budget power, committed downlink transmit power, available power, available link budget power, available downlink transmit power, etc. Transmission power commitment information can facilitate determining a difference between total or available downlink transmit power and committed downlink transmit power. This difference can be referred to by the term ‘headroom’ herein. In an embodiment, downlink transmit power headroom can represent the amount of uncommitted downlink transmit power available for a base station. As such, transmission power commitment information can facilitate determining downlink transmit power headroom that can be committed by downlink channels allowed to exceed a predetermined ceiling power level.

As an example, power ceiling adjustment information can include an indicator value related to not increasing downlink transmission ceiling power where signal-to-noise information is indicative of no significant benefit from increasing downlink transmission power levels. As a further example, power ceiling adjustment information can include an indicator value related to increasing downlink transmission power levels where signal-to-noise information is indicative of improved performance in the downlink performance related to an increase in the transmission power of the downlink channel and where the indicated adjustment to the ceiling would exceed the instant ceiling value.
At 650, access to the power ceiling adjustment information can be facilitated based on satisfaction of a condition related to the power commitment information. Where the power commitment is at or near a predetermined threshold level, the condition can fail to be satisfied and access to the power ceiling adjustment information can be restricted. However, where the power commitment information is indicative of sufficient uncommitted transmission power, the condition can be satisfied and access to the power ceiling adjustment information can be allowed. As an example, where 10% of available transmission power for a base station is committed and the threshold level is a value greater than 45%, the condition can be satisfied and access to the power ceiling adjustment information can be allowed. Continuing the example, this can result in the downlink channel ceiling being elevated and correspondingly committing more transmit power.
FIG. 8 illustrates a method 700 that facilitates adjusting a transmit power parameter based on determined performance parameters in accordance with aspects of the subject disclosure. At 710, method 700 can include receiving instant power ceiling information.

At 724, sign-to-noise information can be determined, at a mobile device, based, at least in part, on the occupied channel information and the pilot channel information. Analysis of occupied channel information relative to pilot channel information can facilitate determination of signal-to-noise information. Signal-to-noise information can be employed to determine the performance of a signal, for example, signal-to-noise information can facilitate determining the performance of a downlink between a base station and mobile device. Signal-to-noise information can include metrics that, for example, can indicate that increasing the transmission power of a downlink transmission can improve the signal quality relative to signal interference.

Power commitment information can be the same as or similar to transmission power commitment information. Transmission power commitment information can include information related to base station utilization of available power for downlink transmissions. In an aspect, transmission power commitment information can include metrics for total available power, total link budget power, total downlink transmit power, committed power, committed link budget power, committed downlink transmit power, available power, available link budget power, available downlink transmit power, etc. In a further aspect, transmission power commitment information can be employed to facilitate determining how much headroom remains in the downlink transmit power of a base station that can be shifted to downlink channels allowed to exceed a predetermined ceiling power level.
At 740, method 700 can include determining, at a base station, power ceiling adjustment information. At this point, method 700 can end. Power ceiling adjustment information can be determined, at a base station, based on satisfaction of a condition related to the signal-to-noise information and the instant power ceiling information.
At 750, access to the power ceiling adjustment information, by a component of the base station, can be based on satisfaction of a condition related to the power commitment information. Where the power commitment is at or near a predetermined threshold level, the condition can fail to be satisfied and access to the power ceiling adjustment information can be restricted. However, where the power commitment information is indicative of sufficient uncommitted transmission power, the condition can be satisfied and access to the power ceiling adjustment information can be allowed.
FIG. 9 illustrates a method 800 that facilitates adjusting a transmit power parameter for a circuit-switched channel in accordance with aspects of the subject disclosure. Method 800 can begin at 802. At 810, method 800 can include receiving instant power ceiling information for a circuit-switched channel. Instant power ceiling information for the circuit-switched channel can be related to the current designated transmit power level for a circuit-switched downlink channel between a base station and a mobile device.
At 820, sign-to-noise information can be received for the circuit-switched channel. Signal-to-noise information can be employed to determine the performance of a signal, for example, signal-to-noise information can facilitate determining the performance of a downlink between a base station and mobile device for a circuit-switched channel. signal-to-noise information can include metrics that, for example, can indicate that increasing the transmission power of a downlink transmission can improve the circuit-switched channel signal quality relative to signal interference.
At 830, power commitment information can be received. Power commitment information can be the same as or similar to transmission power commitment information. Transmission power commitment information can include information related to base station utilization of available power for downlink transmissions. In an aspect, transmission power commitment information can include metrics for total available power, total link budget power, total downlink transmit power, committed power, committed link budget power, committed downlink transmit power, available power, available link budget power, available downlink transmit power, etc. In a further aspect, transmission power commitment information can be employed to facilitate determining how much headroom remains in the downlink transmit power of a base station that can be shifted to downlink channels allowed to exceed a predetermined ceiling power level.
At 840, method 800 can determine if the power ceiling for a circuit-switched channel should be increased. Determining if power ceiling adjustment information should be increased can be based on satisfaction of a condition related to the signal-to-noise information and the instant power ceiling information. As an example, power ceiling adjustment information can include an indicator value related to not increasing downlink transmission ceiling power for a circuit-switched channel where signal-to-noise information is indicative of no significant benefit from increasing downlink transmission power levels. As a further example, power ceiling adjustment information can include an indicator value related to increasing downlink transmission power levels for the circuit-switched channel where signal-to-noise information is indicative of improved performance in the downlink performance related to an increase in the transmission power of the downlink channel and where the indicated adjustment to the ceiling would exceed the instant ceiling value. Where increasing the power ceiling is determined in the affirmative, method 800 continues at 850.
At 850, the downlink transmission power ceiling for a circuit-switched channel can be incremented at the base station. Incrementing the transmission power ceiling can be in predetermined incremental steps, such as, 1 dBm steps, 5% steps, 10 mW steps, etc. Method 800 can proceed to delay 880 before returning to 810 for an additional iteration.
Where increasing the power ceiling is determined in the negative at 840, method 800 continues at 860. At 860, it can be determined if power commitment exceeds a threshold predetermined value. Where the power commitment levels exceed the threshold predetermined level, the condition can be satisfied in the affirmative. However, where the power commitment information is indicative of sufficient uncommitted transmission power, the condition can fail to be satisfied, delivering a negative result. As an example, where 10% of available transmission power for a base station is committed and the threshold level is a value greater than 45%, the condition will not be satisfied and a negative indicator will be result. Where the determination at 860 is a negative result, method 800 continues to delay 880 before returning to 810 for another iteration. Where the determination at 860 is an affirmative result, method 800 continues to 870.
At 870, the downlink transmission power ceiling for a circuit-switched channel can be decremented at the base station. Decrementing the transmission power ceiling can be in predetermined decremental steps, such as, −1 dBm steps, −5% steps, −10 mW steps, etc. Method 800 can then proceed to delay 880 before returning to 810 for an additional iteration.
In an aspect, method 800 can act as a feedback loop facilitating the automatic adjustment of downlink transmit power ceiling levels. Information is gathered at 810-830 for decision making. At 840 it is decided, based on signal-to-noise information, the then current power ceiling, and power commitment information, if the downlink transmit power ceiling level should be increased. If it is to be increased, it is increased at 850, before returning for the next iteration of the loop after any appropriate delay. If it is not to be increased, then at 860 it is determined if the failure to increase is due to too much power already being committed. If it is found that too much power is already committed at 860, then at 870, the downlink transmit power ceiling level is decreased to reduce the level of commitment before returning for the next iteration of the loop. However, if the failure to increase the downlink transmit power ceiling level was not due to the level of power committed, then there is no need to decrease the committee power and method 800 can begin the next iteration.

As used in this application, the terms “component,” “system,” “platform,” “layer,” “selector,” “interface,” and the like are intended to refer to a computer-related entity or an entity related to an operational apparatus with one or more specific functionalities, wherein the entity can be either hardware, a combination of hardware and software, software, or software in execution. As an example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration and not limitation, both an application running on a server and the server can be a component. One or more components may reside within a process and/or thread of execution and a component may be localized on one computer and/or distributed between two or more computers. In addition, these components can execute from various computer readable media having various data structures stored thereon. The components may communicate via local and/or remote processes such as in accordance with a signal having one or more data packets (e.g., data from one component interacting with another component in a local system, distributed system, and/or across a network such as the Internet with other systems via the signal). As another example, a component can be an apparatus with specific functionality provided by mechanical parts operated by electric or electronic circuitry, which is operated by a software or firmware application executed by a processor, wherein the processor can be internal or external to the apparatus and executes at least a part of the software or firmware application. As yet another example, a component can be an apparatus that provides specific functionality through electronic components without mechanical parts, the electronic components can include a processor therein to execute software or firmware that confers at least in part the functionality of the electronic components.
In addition, the term “or” is intended to mean an inclusive “or” rather than an exclusive “or.” That is, unless specified otherwise, or clear from context, “X employs A or B” is intended to mean any of the natural inclusive permutations. That is, if X employs A; X employs B; or X employs both A and B, then “X employs A or B” is satisfied under any of the foregoing instances. Moreover, articles “a” and “an” as used in the subject specification and annexed drawings should generally be construed to mean “one or more” unless specified otherwise or clear from context to be directed to a singular form.
Moreover, terms like “user equipment (UE),” “mobile station,” “mobile,” subscriber station,” “subscriber equipment,” “access terminal,” “terminal,” “handset,” and similar terminology, refer to a wireless device utilized by a subscriber or user of a wireless communication service to receive or convey data, control, voice, video, sound, gaming, or substantially any data-stream or signaling-stream. The foregoing terms are utilized interchangeably in the subject specification and related drawings. Likewise, the terms “access point,” “base station,” “Node B,” “evolved Node B,” “home Node B,” “home access point,” and the like, are utilized interchangeably in the subject application, and refer to a wireless network component or appliance that serves and receives data, control, voice, video, sound, gaming, or substantially any data-stream or signaling-stream to and from a set of subscriber stations or provider enabled devices. Data and signaling streams can include packetized or frame-based flows.
Additionally, the terms “core-network”, “core”, “core carrier network”, “carrier-side”, or similar terms can refer to components of a telecommunications network that typically provides some or all of aggregation, authentication, call control and switching, charging, service invocation, or gateways. Aggregation can refer to the highest level of aggregation in a service provider network wherein the next level in the hierarchy under the core nodes is the distribution networks and then the edge networks. UEs do not normally connect directly to the core networks of a large service provider but can be routed to the core by way of a switch or radio access network. Authentication can refer to determinations regarding whether the user requesting a service from the telecom network is authorized to do so within this network or not. Call control and switching can refer determinations related to the future course of a call stream across carrier equipment based on the call signal processing. Charging can be related to the collation and processing of charging data generated by various network nodes. Two common types of charging mechanisms found in present day networks can be prepaid charging and postpaid charging. Service invocation can occur based on some explicit action (e.g. call transfer) or implicitly (e.g., call waiting). It is to be noted that service “execution” may or may not be a core network functionality as third party network/nodes may take part in actual service execution. A gateway can be present in the core network to access other networks. Gateway functionality can be dependent on the type of the interface with another network.
Furthermore, the terms “user,” “subscriber,” “customer,” “consumer,” “prosumer,” “agent,” and the like are employed interchangeably throughout the subject specification, unless context warrants particular distinction(s) among the terms. It should be appreciated that such terms can refer to human entities or automated components (e.g., supported through artificial intelligence, as through a capacity to make inferences based on complex mathematical formalisms), that can provide simulated vision, sound recognition and so forth.
Aspects, features, or advantages of the subject matter can be exploited in substantially any, or any, wired, broadcast, wireless telecommunication, radio technology or network, or combinations thereof. Non-limiting examples of such technologies or networks include broadcast technologies (e.g., sub-Hertz, extremely low frequency, very low frequency, low frequency, medium frequency, high frequency, very high frequency, ultra-high frequency, super-high frequency, terahertz broadcasts, etc.); Ethernet; X.25; powerline-type networking, e.g., Powerline audio video Ethernet, etc; femto-cell technology; Wi-Fi; worldwide interoperability for microwave access; enhanced general packet radio service; third generation partnership project, long term evolution; third generation partnership project universal mobile telecommunications system; third generation partnership project 2, ultra mobile broadband; high speed packet access; high speed downlink packet access; high speed uplink packet access; enhanced data rates for global system for mobile communication evolution radio access network; universal mobile telecommunications system terrestrial radio access network; or long term evolution advanced.
What has been described above includes examples of systems and methods illustrative of the disclosed subject matter. It is, of course, not possible to describe every combination of components or methods herein. One of ordinary skill in the art may recognize that many further combinations and permutations of the claimed subject matter are possible. Furthermore, to the extent that the terms “includes,” “has,” “possesses,” and the like are used in the detailed description, claims, appendices and drawings such terms are intended to be inclusive in a manner similar to the term “comprising” as “comprising” is interpreted when employed as a transitional word in a claim.
