A base station may receive uplink data identifying uplink performance indicators associated with user equipment connected to the base station, and may receive tuning factors associated with shared channel traffic received by the user equipment and quality of service requirements of the user equipment. The base station may determine a total score associated with utilizing a long duration physical uplink control channel (PUCCH) format for uplink control information based on the uplink data and the tuning factors. The base station may determine that the total score satisfies a threshold score and may switch to the long duration PUCCH format for the uplink control information based on the total score satisfying the threshold score. The base station may perform one or more actions based on switching to the long duration PUCCH format for the uplink control information.

A method, a device, and a non-transitory storage medium are described in which an component carrier management service is provided. The service may monitor data pertaining to a transmit power of an end device and a component carrier of a carrier aggregation. Based on the monitoring, the service may determine when the end device is at or near a maximum transmit power. The service may perform a mitigation procedure to prevent or minimize the end device shutting off a component carrier in a radio transmitter chain.

New Radio (NR)-aware LTE scheduling is provided. An access station for a radio access network includes a first scheduling function. The first scheduling function identifies a User Equipment (UE) device that has a first active wireless connection and a second active wireless connection to the radio access network. The first scheduling function determines that expanded coverage is need for an uplink transmission for the second active wireless connection and obtains uplink scheduling information for the second active wireless connection. The first scheduling function adjusts uplink scheduling for the first active wireless connection such that power sharing is prioritized for uplink time intervals of the second active wireless connection over overlapping uplink time intervals of the first active wireless connection.

Systems and methods for new-radio-aware LTE scheduling

A method of wireless communication over the reverse link. The method may include evaluating a reverse link loading. This evaluation step may involve examining at least two resources associated with reverse link loading within a first time period. Thereafter, a message is broadcast containing information regarding the availability of resources. This message is generated in response to the evaluated reverse link loading. This availability of resources message may correspond with an overload condition, increasing a number of active connections, decreasing the number of active connections, increasing an available transmit rate, maintaining the available transmit rate and/or decreasing the available transmit rate. In one example, the availability of resources message comprises a reverse activity bit.

Method of controlling overload over the reverse link

The input (and output) power of a multi-carrier amplifier can be controlled to allow the amplifier to operate at high RF power levels and still remain within a power rating profile. The amplifier (or amplifiers) power is controlled using an aggregate scaling factor. The aggregate scaling factor is generated from a plurality of amplifier scaling factors. Each amplifier scaling factor is generated based on a comparison of a time-averaged total power and a corresponding threshold.

Methods and devices for controlling RF, multi-carrier amplifier signal power

A method of applying one of several resource distribution algorithms to an incoming call to a communication system. The applied resource distribution algorithm is based on resource parameters obtained from a main scheduler of the communication system. Some of the resource parameters include the type of call, the resource usage and the resource allocation scheme. The resource parameters generally describe the amount of resources that are currently being used by the system and which resources are available to the incoming call. The method of the present invention admits the incoming call to the communication system in accordance with one of the resource distribution allocation schemes. In this manner, the resources of the communication system can be efficiently and fairly distributed to different types of users requesting admission to the communication system.

Voice and data call admission policies for a wireless communication system

When an overload condition is determined to exist at a base station in a wireless communications system based on the number of unsuccessful access attempts to access the system relative to the successful access attempts to access the system, the base station broadcasts a message to each mobile terminal within its coverage area that changes at least one access probe-related parameter associated with at least one of: the number, the frequency, and the power intensity of the access probes made by these mobile terminals as they attempt to establish access to the wireless network. By so limiting these access probes in some manner when an overload condition is present, the interference caused on the reverse link by many mobile terminals attempting access is reduced.

Method of minimizing reverse channel interference caused by an abnormally high number of access attempts in a wireless communications system

A method is disclosed for determining when a request for a higher transmission rate should be granted to a mobile station that currently has access to a communication system to facilitate the maintenance of a performance target (quality of service level) of the reverse link. The method for determining when a mobile station can have access to a higher transmission rate includes obtaining first and second estimated performance indicators for a reverse link of the base station that a mobile station is currently accessing. A blocking threshold value is established. Access at the requested higher transmission rate is based on a comparison of the first and second indicators relative to the established blocking threshold value. If access is denied at the requested higher rate, access will be granted at the next lower rate which will not degrade the performance of the wireless communication system.

Method of determining transmission rate from a mobile station to a base station in a wireless communication system

A system and a method for reverse link power control in a wireless communications network generates power adjust commands for mobiles being served by a network base station in a centralized manner by considering overall system performance when an increased interference condition is detected. In one implementation, a base station power control processor adopts a modified reverse inner loop power control (RILPC) and/or a reverse outer loop power control (ROLPC) algorithm when an increased interference condition is detected. According to the modified RILPC algorithm, a percentage of power-up adjust commands which would normally be generated when E/Nmeasurements for served mobiles do not meet target E/Nlevels are converted to power down-adjust commands, thereby forcing some mobiles to reduce transmit power, at least temporarily, to constrain interference. When the increased interference condition persists, the percentage of power-up adjust commands which are converted to power-down commands may be changed. According to the modified ROLPC algorithm, the power control processor adjusts target E/Nlevels in a centralized manner based on an overall system state so that only a limited number of target E/Nlevels are allowed to increase when frame erasures occur. By preventing a percentage of target E/Nlevel increases, at least temporarily, when frame erasures occur, a percentage of power up-adjust commands are avoided. Therefore, a similar effect to that achieved by the modified RILPC is achieved. In accordance with still a further implementation of the present invention, the modified RILPC algorithm may be used in combination with the modified ROLPC algorithm to provide greater resistance to increased interference conditions.

Method and apparatus for controlling reverse link interference rise and power control instability in a wireless system

A method for controlling access of a subscriber station to a wireless communications system facilitates the maintenance of a performance target of the reverse link and desired geographic coverage of the reverse link. The method for controlling access of a subscriber station to a wireless communications system includes measuring a first performance indicator and a second performance indicator for a reverse link associated with a subscriber station seeking access to a wireless communications system. A blocking threshold value is established based upon the measured second performance indicator and may be adjusted to allow more or less blocking based on any additional metrics that characterize the performance of the current subscriber stations. The decision to grant or deny access of the subscriber station to the wireless communications system is determined based on a comparison of the measured first performance indicator to the established blocking threshold value.

In a method for minimizing reverse link power control overshoot in a wireless communications system, the output power of a mobile station is detected to determine whether it falls outside a dynamic range of the mobile station. If outside the dynamic range, a new output power falling within the dynamic range is calculated and set, and the mobile station is instructed to transmit at the new output power.

Reverse-link power control overshoot considering mobile station transmission limitations

A method and apparatus for estimating the initial power level and transmission rate of a burst on a secondary channel when the secondary channel is on fewer legs of a handoff, such as a soft or softer handoff, than the primary channel. In accordance with the present invention, the initial power level of the burst transmitted over a current secondary channel on a particular leg(s) is a function of a power level of a previous burst transmitted over a previous secondary channel on the identical leg(s) as the current secondary channel. For example, the initial power level of the burst can be based on the power level at the end of the previous burst shortly prior to the termination of the previous burst, where the termination of the previous burst was within a predetermined time interval of the start of the burst. Optionally, the initial power level of a burst can also be additionally adjusted based on characteristics of the communication link of the primary channel, the previous secondary channel, and the current secondary channel. The transmission rate may then be adjusted based on the initial power level determined as described above to obtain a more efficient transmission rate.

Power control and transmission rate parameters of a secondary channel in a wireless communication system

A method for determining the initial power to be allocated to a secondary channel having a desired data rate. An SNR setpoint is first calculated where such setpoint is based on the SNR setpoint of the associated primary channel and system offset values. The initial power is then calculated based on the calculated setpoint.

Forward rate determination of high data rate channels in CDMA air interface

A method that adjusts the power level of a set of forward-link signals of a base station responsive to the loading of the forward link as determined by a power level measurement of the signal set. One power level measurement is a pilot fraction of the forward link. Other power level measurements, such as the signal set's power level, can be used, alone or in combination, instead of or in addition to the pilot fraction of the forward link to adjust the power level of the signal set. The power level of the signal set can be changed in any manner, including by scaling it by a scaling factor, or by increasing the power level by a fixed or a variable amount. The power level measurement of the signal set is obtained during a current time period. The scaling factor that will be used in the subsequent time period is determined using the power level measurement. In one embodiment of the invention, the scaling factor can be obtained from a look-up table that is based on the power level measurement. If the cell containing the base station includes several sectors, the power level of the signal set in a sector is adjusted when the power level measurement in that sector indicates that the power level should be adjusted.
