摘要:
A method for extracting the optimal capacity in a cellular network reverse link involves controlling the reverse link Eb/No setpoint (or other control setting) based on the aggregate reverse link load and channel condition. The cellular network includes a plurality of mobile stations that wirelessly communicate with a base station over a reverse link, using a CDMA or similar communications protocol. The base station calculates a received signal strength indicator (“RSSI”). If the RSSI rises above a designated threshold level, the base station calculates a scaling factor. The base station then scales its reverse link Eb/No setpoint by applying the scaling factor to the Eb/No setpoint. Then, according to the new, scaled Eb/No setpoint, the base station issues closed loop power control commands to the mobile stations, thereby adjusting their transmit power according to the new, scaled Eb/No setpoint.

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.

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.

A method that initiates call blocking responsive to a call-quality measurement of the forward link. The call-quality measurement is a measurement of how well a mobile terminal is able to receive the forward link. One call-quality measurement is a pilot fraction of the forward link, which is a ratio of the pilot's power level to the power level of a set of forward-link signals of a base station. Call blocking is initiated when an average pilot fraction is below a pilot-fraction blocking threshold. The pilot's power level is obtained for a time period, and the signal set's power level is obtained for the same time period. The pilot fraction is determined for the time period, and then used to determine the average pilot fraction for the time period. The average pilot fraction for the current time period is based on a pilot fraction for the current time period, and an average pilot fraction for a previous time period. When the average pilot fraction is below the pilot-fraction blocking threshold, call blocking is initiated. The pilot-fraction blocking threshold is preferably based on: 1) the pilot fraction when the base station is at full load; 2) the size, shape, and terrain of the cell; and 3) the aggressiveness of the overload control. In the preferred embodiment, the signal set includes all of the signals generated by the base station, alternatively, the signal set can include fewer than all the signals generated by the base station. If the cell includes several sectors, the call blocking is initiated on a sector basis when the average pilot fraction of the sector is below the pilot-fraction blocking threshold. Other call-quality measurements, such as the forward link's frame error rate, the number of dropped calls, or the Power Measurement Report Message (PMRM), can be used, alone or in combination, instead of or in addition to the pilot fraction of the forward link to determine whether call blocking should be initiated. Determining whether call blocking should be initiated using one of the other call-quality measurements is performed in a similar manner as for the pilot fraction. Initiating call blocking using several call-quality measurements involves initiating call blocking when any one of the call-quality measurements indicates that call blocking should be initiated. Alternatively, call blocking can be initiated when several of the call quality measurements indicate that call blocking should be initiated.

A rigid plastic wall mount trim block with an integrated flexible center, which acts as a pipe flashing sealing the wall penetration has a back flange for fasting to the wall, a channel integrated in the sides to receive siding materials, and a decorative face with the integrated flexible seal and sizing guide for the installer to cut to fit with the back flange removable so the block may be installed when the siding material predates the installation of the integrated pipe flashing and siding mounting block.
摘要:
Caspase activity and apoptosis are promoted using active, dimeric Smac peptide mimetics of the general formula M1-L-M2, wherein moieties M1 and M2 are monomeric Smac mimetics and L is a covalent linker. Target cancerous or inflammatory cells are contacted with an effective amount of an active, dimeric Smac mimetic, and a resultant increase in apoptosis of the target cells is detected. The contacting step may be effected by administering to a pharmaceutical composition comprising a therapeutically effective amount of The compoundic mimetic, wherein the individual may be subject to concurrent or antecedent radiation or chemotherapy for treatment of a neoproliferative pathology.
