Abstract
"TRANSMISSãO DE INFORMAçãO DE OVERHEAD PARA RECEPçãO DE MúLTIPLOS FLUXOS DE DADOS". Técnicas para transmitir informação de overhead para facilitar a recepção eficiente de fluxos de dados individuais são descritas. Uma estação base pode transmitir múltiplos fluxos de dados em múltiplos canais de dados (ou MLCS). Os MLCs podem ser transmitidos em diferentes tempos e em diferentes sub-bandas de freqüência. A localização de tempo-freqüência de cada MLC pode mudar com o tempo. A informação de overhead indica a localização de tempofreqüência em cada MLC e pode ser enviada como informação de overhead 'composta' e 'embutida'. A informação de overhead composta indica as localizações de tempo-freqüência de todos os MLCs e é enviada periodicamente em cada superquadro. Um dispositivo sem fio recebe a informação de overhead composta, determina a localização de tempo-freqüência de cada MLC de interesse, e recebe cada MLC na localização de tempo-freqüência indicada. A informação de overhead embutida para cada MLC indica a localização de tempo-freqüência daquele MLC no próximo superquadro e é transmitida junto com a carga útil do MLC no superquadro atual."TRANSMISSION OF OVERHEAD INFORMATION FOR RECEPTION OF MULTIPLE DATA FLOWS". Techniques for transmitting overhead information to facilitate efficient reception of individual data streams are described. A base station can transmit multiple data streams over multiple data channels (or MLCS). MLCs can be transmitted at different times and at different frequency subbands. The time-frequency location of each MLC may change over time. Overhead information indicates the location of frequency in each MLC and can be sent as 'composite' and 'embedded' overhead information. Composite overhead information indicates the time-frequency locations of all MLCs and is sent periodically to each superframe. A wireless device receives composite overhead information, determines the time-frequency location of each MLC of interest, and receives each MLC at the indicated time-frequency location. The built-in overhead information for each MLC indicates the time-frequency location of that MLC in the next superframe and is transmitted along with the MLC payload in the current superframe.
