Abstract: PROBLEM TO BE SOLVED: To automatically shift up or down data rates for high data rate channels based on channel quality feedback on dynamic rate switching and scheduling control. SOLUTION: A plurality of mobile units to require data transmission thereto, are determined and then, a metric is determined for each of the plurality of mobile units to require data transmission thereto. On the basis of the relevant metric, then, one mobile unit is selected out of the plurality of mobile units to require data transmission thereto. A transmission rate is then determined based on channel conditions and a coherence time remaining in a fade cycle, and a packet is transmitted to the selected mobile unit at the determined transmission rate.

Abstract: A downlink frame (401) is divided in to similar sized resource blocks (403, 405, 407) with each co-channel sector scheduled to transmit from the beginning of its respective assigned resource block. Transmissions to remote units within the particular sector will occur only within the particular resource block, up to a point where all N resource units have been utilized. Beyond that point, additional transmissions are scheduled to be transmitted at the end of the resource blocks assigned to the other sectors.

Abstract translation: 下行链路帧（401）被划分成类似大小的资源块（403,405,407），每个同频道扇区被调度为从其各自分配的资源块的开始发送。 传输到特定扇区内的远程单元将仅发生在特定资源块内，直到所有N个资源单元都被利用。 除此之外，额外的传输被安排在分配给其他扇区的资源块的末尾被传送。

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-linear 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: A communication system (100) includes a forward link (106) from a base station (102) to multiple mobile units (104), the forward link having multiple shared channels (SHCH's) (109), multiple shared control channels (SHCCH's) (108), and multiple dedicated pointer control channels (DPTRCH's) (107), and utilizes HARQ error control for error detection and error correction. The mobile unit, when listening to the DPTRCH, uses a SHCCH pointed to by the DPTRCH to demodulate and decode data on the SHCH. Throughput problems may arise when the mobile unit combines and decodes the SHCH data that is intended for a different mobile unit or incorrectly decodes SHCH data that is intended for the mobile unit. In order to improve the data throughput of the system, the system employs a flush test (902, 904, 1004, 1008) and an energy detector test (1100, 1202) to prevent improperly decoded data blocks from corrupting properly decoded data blocks.

Abstract translation: 通信系统（100）包括从基站（102）到多个移动单元（104）的前向链路（106），具有多个共享信道（SHCH）（109），多个共享控制信道（SHCCH） 108）和多个专用指针控制信道（DPTRCH）（107），并且利用HARQ错误控制进行错误检测和纠错。 移动单元在收听DPTRCH时使用由DPTRCH指向的SHCCH对SHCH上的数据进行解调和解码。 当移动单元组合和解码旨在用于不同移动单元的SHCH数据或不正确地解码旨在用于移动单元的SHCH数据时，可能出现吞吐量问题。 为了提高系统的数据吞吐量，系统采用冲洗测试（902,904,1004,1008）和能量检测器测试（1100,1202），以防止不正确解码的数据块破坏正确解码的数据块。

Abstract: A method and apparatus (300) for performing H-ARQ transmission is described herein. Bits received on a first transmission are stored (301) and combined with die bits received on later transmissions (304) thereby increasing the likelihood of a correct decoding on later transmissions (304). Additionally, a plurality of coding schemes (eg., Convolution Codes, Block Turbo Codes, Convolution Turbo Codes, Low Density Parity Check Codes,..., etc.) are utilized, with an information element being reserved to signal what form of H-ARQ is being utilized.

Abstract: The present invention provides a method for enabling transparent relaying of data in order to improve the performance of a cellular system. Particularly, relaying on the uplink is performed by fixed entities called Transparent Relays (TR). The base station may allocate one or more TRs to relay the data transmissions associated with a particular CID (e.g., a particular subscriber station) on the uplink.

Abstract: Se describe aqui un metodo y un aparato para efectuar una transmision H-ARQ. Los bits recibidos en una primera transmision son almacenados y combinados con los bits recibidos en transmisiones posteriores, incrementando por lo tanto la probabilidad de una descodificacion correcta sobre las ultimas transmisiones. Adicionalmente, se utiliza una pluralidad de esquemas de codificacion (por ejemplo, Codigos Convolucionales, Turbo Codigos de Bloques, Turbo Codigos Convolucionales, Codigos de Verificacion de Parte de Baja Densidad,..., etc.), con un elemento de informacion que esta reservado para senalar que forma de H-ARQ esta sendo utilizada.
