Em redes celulares de múltiplas entradas e múltiplas saídas (MIMO), certos escalonadores têm duas fases independentes: a primeira seleciona um grupo de usuários com base no critério do escalonador, e a segunda atribui os usuários selecionados às antenas de transmissão usando um esquema de atribuição tomando em consideração a maximização da capacidade. Outros agendadores selecionam diretamente entre os canais disponíveis entre os usuários e a estação base de forma centralizada. Os escalonadores da primeira categoria podem ser implementados com menor complexidade em comparação com os escalonadores da segunda categoria. Para a primeira categoria, propomos três esquemas de atribuição quase ótimos com baixas complexidades. Realizamos uma simulação em que foi considerada a mobilidade dos usuários que demonstrou o desempenho superior de nossos esquemas de atribuição. Além disso, demonstramos analiticamente sua eficiência.

Abstract: In multiple-input multiple-output (MIMO) cellular networks, certain schedulers have two independent phases: the first selects a group of users based on the scheduler criterion, and the second assigns the selected users to the transmit antennas by using an assignment scheme taking into consideration capacity maximization. Other schedulers directly select among the available channels between users and the base station in a centralized way. The schedulers of the first category can be implemented with lower complexity compared with the schedulers of the second category. For the first category, we propose three near-optimal assignment schemes with low complexities. We conducted a simulation in which the mobility of users was considered that demonstrated the superior performance of our assignment schemes. Furthermore, we analytically demonstrate their efficiency.
