Abstract: A method for assigning resources to FS and FNS users, for example, in an OFDM wireless communication system 100, including assigning a first frequency resource to at least one FS user during a time interval, wherein the first frequency resource includes at least two near contiguous sub-carriers, and assigning a second frequency resource to at least one FNS user during the same time interval, the second frequency resource includes for each FNS user at least two non-contiguous sub-carriers, wherein the first and second frequency resources are part of a common frequency channel.

Abstract: Una entidad de infraestructura de comunicaciones inalámbricas configurada para asignar recursos de radio, en una trama de radio, a una terminal inalámbrica compatible con un primer protocolo y a una terminal inalámbrica compatible con un segundo protocolo. La trama de radio incluye una primera región de recursos de protocolo y una segunda región de recursos de protocolo. La trama de radio incluye un primer mensaje de control de asignación de protocolo que asigna recursos dentro de la primera región de recursos de protocolo a la terminal inalámbrica compatible con el primer protocolo, y un segundo mensaje de control de asignación de protocolo que asigna recursos dentro de la segunda región de recursos de protocolo a la terminal inalámbrica compatible con el segundo protocolo.

Abstract: A method and apparatus for performing H-ARQ transmission is described herein. Bits received on a first transmission are stored and combined with the bits received on later transmissions thereby increasing the likelihood of a correct decoding on later transmissions. Additionally, a plurality of coding schemes (e.g., Convolutional Codes, Block Turbo Codes, Convolutional Turbo Codes, Low Density Party Check Codes, . . . , etc.) are utilized, with an information element being reserved to signal what form of H-ARQ is being utilized.

Abstract: A method for providing a low-feedback scheme for link-quality reporting based on the EESM technique is provided herein. During operation, a node will analyze the current channel conditions and determine a non-liner approximation of the carrier to interference plus noise ratio (CINR). The non-linear approximation is sent to a communication unit as a channel-selectivity report, causing the communication unit to utilize the report to assist with modulation and coding selection.

Abstract: En la presente se describen un metodo y un aparato para realizar la transmision de H-ARQ. Los bits recibidos en una primera transmision se almacenan y combinan con los bits recibidos en transmisiones posteriores incrementando consecuentemente la probabilidad de una decodificacion correcta en transmisiones posteriores. Ademas, se utiliza una pluralidad de esquemas de codificacion (por ejemplo, Codigos de Convolucion, Turbo Codigos de Bloque, Turbo Codigos de Convolucion, Codigos de Verificacion de Paridad de Baja Densidad, ..., etc.), con un elemento de informacion que se reserva para senalizar cual forma de H-ARQ se utiliza.

Abstract: A mobile station (110) selects an initial data rate for communication betwee n base station (107) and mobile station (110). Mobile station (110) communicat es the selected initial data rate to base station (107) through uplink (112). Base station (107) determines a difference level of interference condition experienced by mobile station (107) between a time when the initial data rat e was selected by mobile station (110) and a time when base station (107) prepares to communicate to mobile station (110). Base station (107) selects a final data rate for transmission from base station (107) to mobile station (110) based on the determined difference level of interference condition. As such, the initial data rate may be modified to the final data rate while maximizing the down link capacity.

Abstract: A method in a communication system (100) includes transmitting from a source user (101) a first data packet (111) over a first time frame (121) having a finite time period (131), transmitting from source user (101) a second data packet (112) over a second time frame (122) immediately subsequent to first time frame (121), detecting an acknowledgment of acceptable reception of data packet associated with either first or said second data packets (111 and 112), repeating transmission of first and second data packets (111 and 112) in a sequence of first and second time frames (121 and 122) in a time frame sequence (190) until the detection.

Abstract: A generic structure of Hybrid ARQ using Turbo Codes is provided which requires the function of a) channel coding, b) redundancy selection, c) buffering and max-ratio diversity combining, d) channel decoding, e) error detection and f) sending back an acknowledgement to the transmitter. The functions (a) and (b) are performed at the transmitter while functions (c) to (f) are performed at the receiver. The initial code rate can be explicitly communicated to the receiver or blindly detected.
