O Advanced Evolved Universal Terrestrial Radio Access (Advanced E-UTRA), denominado LTE-Advanced, foi padronizado no 3rd Generation Partnership Project (3GPP) como candidato ao IMT-Advanced. LTE-Advanced suporta diversidade de transmissão de recursos ortogonais espaciais (SORTD) [1],[2] para sinais ACK/NACK e solicitações de agendamento (SRs), que são usadas para controlar solicitações de repetição automática híbrida de downlink (HARQs) e gerenciar recursos de rádio de uplink com base no tráfego de dados de uplink, respectivamente. Tanto os sinais ACK/NACK quanto os SRs são transportados através de um canal físico de controle de uplink (PUCCH) [3], e um formato PUCCH comum é usado para sinais ACK/NACK e SRs. Se for utilizado SORTD, a estação base atribui recursos mutuamente ortogonais a cada antena incluída no equipamento de usuário (UE) para sinais ACK/NACK e SRs; portanto, o número de recursos necessários aumenta com o número de antenas de transmissão no UE. Neste artigo, estudamos o método de redução de recursos para sinal ACK/NACK e SR no caso de SORTD utilizando o conceito de recurso comum. Além disso, investigamos um esquema de rotação de fase para recursos comuns para melhorar o desempenho de detecção de SR.

Abstract: Advanced Evolved Universal Terrestrial Radio Access (Advanced E-UTRA), called LTE-Advanced, has been standardized in the 3rd Generation Partnership Project (3GPP) as a candidate for IMT-Advanced. LTE-Advanced supports spatial orthogonal-resource transmit diversity (SORTD) [1],[2] for ACK/NACK signals and scheduling requests (SRs), which are used to control downlink hybrid automatic repeat requests (HARQs) and manage uplink radio resources based on uplink data traffic, respectively. Both ACK/NACK signals and SRs are carried via a physical uplink control channel (PUCCH) [3], and a common PUCCH format is used for both ACK/NACK signals and SRs. If SORTD is used, the base station assigns mutually orthogonal resources to each antenna included in the user equipment (UE) for ACK/NACK signals and SRs; hence, the number of required resources increases with the number of transmitting antennas in the UE. In this paper, we study the resource reduction method for ACK/NACK signal and SR in case of SORTD using the concept of common resource. In addition, we investigate a phase rotation scheme for common resources to improve the SR detection performance.
