Abstract:
PROBLEM TO BE SOLVED: To improve operation of a MAC layer of an access terminal. SOLUTION: The access terminal is configured for wireless communication with an access network within a sector. The access terminal includes a transmitter 2608 for transmitting a reverse traffic channel to the access network, an antenna 2614 for receiving signals from the access network, and a processor 2602 and memory 2604 in electronic communication with the processor 2602. Instructions are stored in a memory 2604. The instructions are arranged to estimate the current value of the reverse activity bit transmitted from the access network. The allocation of electric power for the flow may be increased or decreased based on the estimated current value of the reverse activity bit. COPYRIGHT: (C)2011,JPO&INPIT

PROBLEM TO BE SOLVED: To improve operations in a medium access control (MAC) layer of an access terminal especially in a wireless communication system. SOLUTION: The access terminal 2606 is configured for wireless communications with an access network in a sector, and includes a transmitter 2608 to transmit a reverse traffic channel to the access network, an antenna 2614 to receive signals from the access network, a processor 2602 for electronic communications, and a memory 2604. Commands are stored in the memory 2604, and arranged so as to estimate a current value for a reverse activity bit transmitted from the access network. Per flow power allocation may be increased or decreased based on an estimated current value of the reverse activity bit. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a method of reverse link (RL) data rate allocation in a high data rate system such as 1xEV-DO. SOLUTION: Rate shaping of a throughput profile for multiple access terminals (ATs) is performed by adjusting transition probabilities associated with a data rate allocation algorithm. The RL maximum data rate per AT is adjusted to reduce the loading in a designated area and result in rate shaping of the cell and/or sector. The maximum data rates are adjusted as a function of the FL signal to Interference and Noise Ratio (SINR), such as measured per serving sector or as a captured sum total of FL SINR. Further, the maximum data rates are adjusted as a function of differences in rise over thermal values between neighboring sectors. COPYRIGHT: (C)2010,JPO&INPIT

PROBLEM TO BE SOLVED: To provide systems and methodologies that facilitate quality of service (QoS) differentiation and/or prioritization across a plurality of base stations included in wireless communication systems.SOLUTION: The system can include components and/or devices that: obtain resource allocations for cells controlled by a local base station; ascertain whether or not the resource allocations satisfy quality of service targets associated with data flows traversing through cells controlled by the local base station; and dispatch inter cell interference coordination indicators to remote base stations that have a proximate relationship defined by an X2 channel between the local base station and the remote base stations.
Abstract:
PROBLEM TO BE SOLVED: To provide cooperative, autonomous and scheduled resource allocation for a distributed communication system.SOLUTION: There is implemented a method of determining whether a current power allocation grant 1374 for a flow on an access terminal has been received from an access network. If the current power allocation grant 1374 is still active, a current power allocation 1338a for the flow is set equal to the current power allocation grant 1374. If the current power allocation grant 1374 has not been received, the current power allocation 1338a for the flow is determined.
Abstract:
PROBLEM TO BE SOLVED: To improve operation of a media access control (MAC) layer of an access terminal. SOLUTION: An access terminal includes: a transmitter that transmits a reverse traffic channel to an access network; an antenna that receives a signal from the access network; a processor that performs electronic communication with a processor; and a memory. An instruction stored in the memory determines whether the current electric power allocation permission 1374 in a flow of the access terminal is the one received from the access network or not. If the current electric power allocation permission 1374 is still active, the current electric power allocation 1338a for the flow is set equally to the current electric power allocation permission 1374. If the current electric power allocation permission 1374 is not received yet, the current electric power allocation 1338a for the flow is decided. COPYRIGHT: (C)2010,JPO&INPIT
Abstract:
Reverse Link (RL) data rate allocation in a High Data Rate (such as 1xEV-DO) system as a function of Forward Link (FL) channel quality. Rate shaping of a throughput profile for multiple Access Terminals (ATs) is performed by adjusting transition probabilities associated with a data rate allocation algorithm. The RL maximum data rate per AT is adjusted to reduce the loading in a designated area and result in rate shaping of the cell and/or sector. In one embodiment, the maximum data rates are adjusted as a function of the FL Signal to Interference and Noise Ratio (SINR), such as measured per serving sector or as a captured sum total of FL SINR. In still another embodiment, the maximum data rates are adjusted as a function of differences in rise~over-thermal values between neighboring sectors.

Abstract:
A method of transmitting a packet is provided. The method includes the steps of selecting a payload size from a payload profile, identifying a power level associated with the selected payload size for a transmission mode of the packet, determining whether transmission conditions are satisfied and selecting a different payload size if the conditions are not satisfied. A method of obtaining current power allocation for flows on an access terminal by setting a power allocation is also disclosed, as well as a wireless access terminal able to transmit a packet as described above, and other apparatus for performing the methods as provided.
