摘要： A method and apparatus for establishing an active set of carriers from a plurality of available carriers for a wireless receiver. The active set of carriers can be determined from the plurality of available carriers for the wireless receiver. An indication of which carriers are in the active set can be sent to the wireless receiver, such as a receiver in a mobile communication device. The receiver or mobile communication device can monitor only those carriers that are listed in the active set of carriers.

摘要： Methods and systems are provided for determining a transmission format using an effective SNR. The method comprises determining (105) a pilot SNR for at least one time period in a frame, mapping (110, 115, 120, and 125) the scaled SNRs of the frame to a second SNR for at least one transmission format, and selecting (130) the transmission format based on the second SNRs.

摘要： 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.

摘要： In order to address the above-mentioned need, a method and apparatus for assigning time-domain resources to a wireless receiver is provided herein. During operation a resource assigned to a particular node will comprise a particular-length subframe having a unique combination of a number of contiguous slots and a slot start time. The subframe will repeat after a predetermined number of slots to form a subframe pattern. For a given frequency resource (group of subchannels), each node to which the base station is transmitting a packet will have a unique subframe length, starting slot, and repetition time period. Because each node will be assigned a subframe pattern having a particular length, and because each node's transmissions will begin at varying slots, the resources may be assigned to multiple nodes without having any transmissions overlap.

摘要： A method and apparatus for sharing a unique identifier among a plurality of receivers. A network controller (140) can establish at least one unique identifier and at least one corresponding time slot for which the unique identifier is valid for each assigned carrier of a wireless receiver (120). The network controller does this by determining at least one unique identifier and at least one corresponding time slot for which the unique identifier is valid for each assigned carrier of the wireless receiver and then sending an indication of the unique identifier(s), time slot(s), and carrier(s) to the wireless receiver. The wireless receiver receives the indication and then monitors at least one channel using the at least one unique identifier during the at least one corresponding time slot indicated.
