In a wireless communication system, a method includes assigning an initial portion of a list of resource block group for each of a plurality of cells such that the resource block groups are spread across the plurality of cells in a non-contiguous order spaced out in frequency. In addition, the method assigns a secondary portion of the list of resource block groups for each of a plurality of cells wherein the secondary portion is assigned in a reverse order and alternating from the initial portion of the list of resource block groups of each of the other plurality of cells.

A method and Node B are disclosed for allocation of “sticky” resources in an Orthogonal Frequency Division Multiplexing communication system. The Node B comprises a scheduler that is configured to make a sticky resource allocation to a user equipment, determine that a transmit power level allocated for transmissions to the user equipment should be adjusted, determine whether the resources allocated to the user equipment comprise a Quadrature Phase Shift Keying (QPSK) modulation scheme, and in response to determining that the resources allocated to the user equipment comprise a QPSK modulation scheme, adjust the allocated transmit power level without informing the user equipment of the adjustment. The Node B further may condition the determination to adjust the allocated transmit power level without informing the UE of the adjustment based on a size of the adjustment.

A CDMA system according to an embodiment of the invention employs a technique for power optimized user loading that obtains a desired allocation of different radio configuration calls. The technique takes advantage of the relatively low power requirements of RC3 calls for low load conditions, while increasing the number of RC4 calls for high load conditions. As the load increases, the system determines a target combination of RC3 and RC4 calls based upon the current average power per link measurements for RC3 and RC4 calls, and based upon the power limitations of the system. The technique strives to maximize the capacity of the system while maintaining operation below the overall power limit.

A CDMA system according to an embodiment of the invention employs a technique for power optimized user loading that obtains a desired allocation of different radio configuration calls. The technique takes advantage of the relatively low power requirements of RC3 calls for low load conditions, while increasing the number of RC4 calls for high load conditions. As the load increases, the percentage of RC4 calls increases while the percentage of RC3 calls decreases. The technique strives to minimize overall power consumption in the system for all call load conditions, by maximizing the number of RC3 calls at any given time while keeping Walsh code resources available for both new calls and hand-in traffic.

A method and information processing system are provided for dynamically encoding a control channel for transmitting messages to a wireless device based on performance capability information associated with the wireless device. The method includes determining that a wireless device (104) has registered with a base station (116). A device profile (128) associated with the wireless device (116) is retrieved from a register (122). A set of performance capabilities associated with the wireless device is determined (408) in response to the retrieving. A coding type for a control channel for sending messages to the wireless device (104) is determined (410) based on the set of performance capabilities associated with the wireless device (104).
摘要:
A method for substantially reducing the frame erasure rate (FER) to approximately 1 percent dynamically changes the power down to power up ratio from 100 to 1 to 200 to 1 to minimize subsequent frame erasures. During call startup periods the method (60) loosely monitors the power. Whereas for consecutive error bursts of frame erasures, the process (80) does not change the power threshold. This power threshold is the level received signals are compared against to determine if a power up or a power down step needs to be performed. Likewise, RF fades will not cause the power threshold to be increased. Further, should the power threshold exceed its maximum, it is reset by process (90).

A fixed base-site (115) periodically pages subscribers (120) in a paging area (100). To prolong the battery life of the subscribers (120), paging groups (520) are not sent to subscribers (120) as often when the paging load is small. Since the subscribers (120) support discontinuous receive, processing of the pages will not take place as frequently and thus a battery savings is realized. When the fixed base-site (115) receives more pages than can be supported without exceeding a predetermined delay, the fixed base-site (115) dynamically increases the frequency that paging groups (520) are transmitted to subscribers (120). When the paging load decreases, the fixed base-site (115) dynamically decreases the frequency that paging groups (520) are transmitted to subscribers (120) and again a savings in battery life is realized.
摘要:
A system and method of evaluating the radio coverage of a geographic area serviced by a digital cellular radiotelephone communication system is described which comprises a plurality of base stations each having a transmitter and a receiver and a plurality of mobile units having co-located transmitters and receivers for transmitting and receiving communication message signals between the base stations and a mobile unit. During operation, the position of at least one of the mobile units operating within the geographic area is located when a call is received by a base station. The base station monitors the signal quality of the call and collects information relevant to the actual performance of the communication system. The mobile unit location and corresponding signal quality data are passed from the base station to a central operation and maintenance unit which collects the data, performs all necessary analytic and arithmetic computations, and provides a user-friendly representation of the characteristics of the radio coverage. With this representation of the radio coverage characteristics, the system operator can quickly and efficiently diagnose coverage deficiencies and take the necessary corrective action. By continuously monitoring subscriber calls and updating the pictographic representations, the system operator can actually observe the effect of the adopted modifications in a pseudo real-time fashion.
