Gangguan antara sel antara pautan atas dan pautan bawah dalam sistem komunikasi paket CDMA, menggunakan skim TDD kongsi, dinilai di bawah persekitaran selular. Didapati bahawa gangguan antara stesen pangkalan jarang merendahkan daya tampung pautan atas, tetapi gangguan antara stesen mudah alih secara ketara merendahkan daya tampung pautan bawah. Skim kawalan kuasa penghantaran dicadangkan untuk meningkatkan daya pemprosesan pautan ke bawah. Skim yang dicadangkan meningkatkan kuasa penghantaran paket pautan bawah apabila ia dihantar semula, dan dengan itu, menambah baik nisbah isyarat kepada gangguan bagi paket penghantaran semula pautan bawah. Simulasi komputer menunjukkan bahawa skim ini meningkatkan daya tampung pautan bawah tanpa mengorbankan daya tampung pautan atas sehingga daya tampung pautan atas mencapai nilai maksimum.

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.
