Abstract: A base station (103) assigns a set of mobile stations (101) to a group wherein the group will share a set of radio resources (770). A shared control channel information element (501) is sent to the group of mobile stations (101) and provides a bitmap having fields for group ordering (511), resource allocations (530), continuation resources (540) for HARQ, and an ordering pattern (513). If a mobile station requires retransmission it will access the resources indicated by the continuation resources field (54) in order to receive data. The HARQ blocks may be assigned to a mobile station based upon an index (601) which may correspond to the mobile station vocoder rate. Further, HARQ subgroups may be defined to associate subgroups of mobile stations with specific HARQ transmission opportunities on the super-frame and allocated by a rotating bitmap.

Abstract: A wireless communication infrastructure entity assigns a plurality of schedulable wireless communication entities to a group wherein each entity is assigned a location within the group. The infrastructure entity indicates which of the plurality of schedulable wireless communication entities assigned to the group have been assigned a radio resource, for example in a first bitmap (510), and indicates radio resource allocation policy information (520) and indicates a weighting for each assigned wireless communication entity, for example, in a second bitmap (530), to the schedulable wireless communication entities that have been assigned a radio resource.

Abstract: 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.

Abstract: 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. The system comprises a receiver (24) configured to detect pilot signals, a data storage (36), and a processor (26) coupled to the receiver and data storage. The data storage (36) comprises tables of capacity mapping functions and Q factors for each transmission format The processor (26) comprises a set of instructions to convert SNRs of different pilot signals to a second SNR using the tables and Q factors and select the transmission format based on the second SNR.

Abstract: 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.

Abstract: 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.

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.

Abstract: A processor (804) locates a position for displaying an image on at least one of first and second display portions (202, 204) of a display (200) including a visible seam (206) between the display portions (202, 204). The processor (804) then cooperates with the display (200) to display the image in the position such that, when the position extends beyond one of the display portions (202, 204) and onto a next one of the display portions (202, 204), a portion of the image corresponding to the location of the visible seam (206) is omitted.
