A interferência intercelular entre uplinks e downlinks em sistemas de comunicação por pacotes CDMA, empregando um esquema TDD compartilhado, é avaliada em ambientes celulares. Verifica-se que a interferência entre estações base raramente degrada o rendimento da ligação ascendente, mas a interferência entre estações móveis degrada substancialmente o rendimento da ligação descendente. Um esquema de controle de potência de transmissão é proposto para melhorar o rendimento do downlink. O esquema proposto aumenta a potência de transmissão dos pacotes de downlink quando eles são retransmitidos e, assim, melhora a relação sinal-interferência dos pacotes de retransmissão de downlink. A simulação computacional mostra que este esquema aumenta a taxa de transferência do downlink sem sacrificar a taxa de transferência do uplink até que a taxa de transferência do uplink atinja um valor máximo.

Abstract: The inter-cell interference between uplinks and downlinks in CDMA packet communication systems, employing a shared-TDD scheme, is evaluated under cellular environments. It is found that interference between base stations rarely degrades uplink throughput, but interference between mobile stations substantially degrades downlink throughput. A transmission power control scheme is proposed to improve the downlink throughput. The proposed scheme increases the transmission power of downlink packets when they are re-transmitted, and thus, improves the signal-to-interference ratio of the downlink re-transmission packets. Computer simulation shows that this scheme increases downlink throughput without sacrificing the uplink throughput until the uplink throughput reaches a maximum value.
