Neste artigo, estudamos o desempenho da cooperação da estação base (BS) para transmissão de downlink. Com base em um modelo multicelular de Wyner modificado, é proposto um esquema de escalonamento intracelular oportunista. Em seguida, derivamos uma expressão de forma fechada para a capacidade de taxa de soma do esquema proposto no canal de desvanecimento plano de Rayleigh. Além disso, provamos que o esquema oportunista pode ser considerado como fornecendo um esquema de formação de feixe de downlink para alcançar um limite inferior mais restrito para a capacidade de taxa de soma de downlink. Os resultados numéricos confirmam nossa análise teórica.

Abstract: In this paper, we study the performance of base station (BS) cooperation for downlink transmission. Based on a modified Wyner multicell model, an opportunistic intra cell scheduling scheme is proposed. Then, we derive a closed-form expression for the sum-rate capacity of the proposed scheme in the Rayleigh flat-fading channel. Also, we prove that the opportunistic scheme can be regarded as providing a downlink beam-forming scheme to achieve a tighter lower bound for the downlink sum rate capacity. Numerical results confirm our theoretical analysis.
