Abstract: Un aparato (1900) de comunicación que es una estación operativa de 20 MHz que comprende: un receptor (1906) que está configurado para recibir una trama (950) de desencadenamiento que asigna unidades de recursos, RU, para acceso aleatorio y otra trama que incluye un elemento (1100) de parámetro de acceso aleatorio que comprende un primer campo que indica un valor (1112) mínimo de ventana de contención de OFDMA, OCW, OCWmín, y un segundo campo que indica un valor (1114) máximo de OCW, OCWmáx; y circuitería (1904) de control que está configurada para controlar un procedimiento (800) de acceso aleatorio basado en OFDMA de enlace ascendente, UORA, usando el OCWmín y el OCWmáx, y estando la circuitería de control configurada adicionalmente para: disminuir un contador de retroceso de OFDMA, OBO, a cero cuando el contador de OBO no es mayor que un número de RU disponibles para acceso aleatorio en la trama de desencadenamiento, siendo las RU disponibles RU sin restricciones para usarse para la estación operativa de 20 MHz, en el que las RU incluyen al menos una RU restringida para usarse para la estación operativa de 20 MHz; y de lo contrario, disminuir el contador de OBO por el número de RU disponibles para acceso aleatorio.

Abstract: Disclosed are transmission equipment and a method for sending control messages in which the processing time and power consumption at the receiving end are reduced by improving the efficiency of reception processing at the receiving end. At a base station (100), a message generating unit (103) generates a control message and an OFDM communication unit (104) transmits a frame including the control message. The control message (300) has a unicast region (320) and broadcast/multicast regions (310), and scheduling information units (330) comprising a single MS-ID, a plurality of information elements (IE) that are transmitted to each mobile station (200) corresponding to this MS-ID, and an IE number indicator, which is the number information of this plurality of IEs, are included in a group of scheduling information units arranged in the unicast region (320).

Abstract: To improve the frequency diversity effect by preventing the related bits in the encoded data from being biased to the specified carrier in the case of performing the multicarrier operation. A modulated symbol sequence is segmented in a data segmentation section (116), and the segmented modulated symbol blocks are mapped on a plurality of carriers in a segment mapping section (120). The data segmentation section (116) groups each of K parts in the modulated symbol sequence into the same number of N groups, cyclically shifts the N groups for the respective parts of any (K-1) parts with shift amounts which differ among the parts, and substitutes the cyclically-shifted groups of the plurality of parts in the modulated symbol sequence with one another among the parts to segment the groups into a plurality of blocks.
Abstract translation: 在执行多载波操作的情况下，通过防止编码数据中的相关比特偏置到指定的载波来提高频率分集效应。 调制符号序列在数据分割部分（116）中分段，并且分段调制的符号块被映射在段映射部分（120）中的多个载波上。 数据分割部分（116）将调制符号序列中的K个部分中的每一个分组成相同数量的N个组，对于任何（K-1）部分的各个部分的N组循环移位，其中部分 并且将这些部分中的调制符号序列中的多个部分的循环移位组替换为将组分割成多个块。
