  • Publication number: 20070274288
    Abstract: During operation a wireless terminal will receive instructions assigning it to a group of wireless terminals sharing a common set of resources. The terminal will also receive an overflow allocation policy indicating resources that are to be utilized if there are more assigned resources that group resources.

  • Publication number: 20070211620
    Abstract: A communication system distributes, in the time domain, acknowledgment transmissions by a group of access terminals sharing a same time domain resource. A position of one or more access terminals in the group of access terminals is determined and each of the one or more access terminals then sends an acknowledgment transmission, such as an acknowledgment or negative acknowledgement, in a time slot that is N time slots after the shared time domain resource, where N is a function of the position of the access terminal in the group of access terminals.

  • Publication number: 20070214400
    Abstract: A method and system for method for transmitting data in a communication network employing HARQ. The method includes a first step 502 of grouping data to be transported into a first group and a second group in accordance to a decision parameter, such as data size. A next step 504 includes concatenating data from the first group and encoding into a multi-user packet. A next step 502 includes encoding the data into a plurality of data packets. A next step 506 includes assigning available traffic resources to encoded packets. A next step 506 includes transmitting at least a first transmission of the encoded packets. A next step 510 includes reassigning a portion of said traffic resources for which a positive acknowledgement has been determined to uninitiated packets or to assist with one or more ongoing transmissions.

  • Patent number: 7071777
    Abstract: The present invention discloses a system and a method for memory-based predistortion to reduce the distortion effects introduced by a power amplifier. The distortion effects include both memoryless and memory effects. The input and the corresponding output values of the power amplifier are measured to determine models used for predistortion. Using these models, first, an amplitude memory signal representing the amplitude memory effects of the power amplifier is obtained. Then, the amplitude memory signal is subtracted from the input signal. On the resulting signal, memoryless amplitude predistortion and memory-based phase predistortion are performed to get a predistorted signal. Further, an inverse model of the linear response of the power amplifier is implemented on the predistorted signal. Finally, the output of the inverse model is amplified by the power amplifier to obtain an output signal having reduced memoryless and memory-based effects.
