Abstract: In one example embodiment, a network control node includes a memory having computer-readable instruction stored therein, and a processor. The processor is configured to execute the computer-readable instructions to determine an uplink correction parameter based on at least one of network loading conditions and a modulation coding scheme used for transmission of data packets on an uplink channel from a user equipment to the network control node, determine a target signal to interference plus noise ratio (SINR) for the user equipment based on the uplink correction parameter, and adjust the modulation coding scheme based on the determined target SINR.

Abstract: A method for transmitting a signal in a wireless communications network includes calculating, by a network element, first and second average powers. The first average power is associated with a first time period of a downlink transmission between a transmitter associated with the network element and at least one user, and the second average power is associated with a second time period of the downlink transmission. The method includes transmitting, by the transmitter, the signal at one of a rated transmission power and a boosted transmission power based on a first threshold value associated with the first average power and a second threshold value associated with the second average power. The rated transmission power is less than or equal to a long-term average power limit associated with a power amplifier of the transmitter, and the boosted transmission is greater than the rated power.

Abstract: 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.

Abstract: The present invention provides a method for dynamically estimating noise floor by continuously updating a noise floor value based on the noise floor value and sampled receive strength indications. In an alternative, the noise floor may be updated based on sampled receive strength indications and the reverse link loading value. In yet another alternative, the noise floor may be updated based on sampled receive strength indications and a range relative to a reference noise floor value.

Abstract: For carrier growth planning in a wireless network, one or more airlink data transfer performance indicators are measured for a plurality of wireless units at a number of different times. The performance indicators may include user perceived throughput (UPT) and transmission latency or delay, as relating to batch or burst data transfers. Typically, the performance indicators are measured as a function of airlink loading, such as percentage of busy slots. After one or more optional statistical procedures, such as averaging, the performance indicators are compared to one or more performance criterion. In the case of UPT, for example, the performance criteria may be a set or range of minimum desired UPT values, for different loading levels, as established by the service provider. If the performance indicators meet the criteria, this indicates against adding airlink bandwidth in an effort to improve performance. Otherwise, increased airlink bandwidth may be warranted.

Abstract: 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.

Abstract: 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 Eb/No measurements for served mobiles do not meet target Eb/No levels 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.

Abstract: 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.
