Abstract

métodos, sistemas e dispositivos para a comunicação sem fio são descritos. um equipamento de usuário (ue) pode identificar a informação de controle de uplink (ul) (uci) para transmissão durante um subquadro. o ue pode, então, selecionar um canal ul no qual transmitir a uci com base no fato de se um canal ul de controle de dados compartilhado emprega a programação com base em competição. por exemplo, múltiplos ues podem competir por acesso ao mesmo canal compartilhado em ul físico (pusch) programado de forma semipersistente (sps). cada ue pode utilizar uma mudança cíclica de sinal de referência de demodulação diferente (dmrs) para identificar suas transmissões. em alguns casos, alguma uci, tal como a informação sobre o estado do canal (csi), pode ser transmitida em um pusch com base em competição, enquanto outra uci, tal como a informação de aviso de recebimento, pode ser transmitida em um canal de controle de uplink físico (pucch). em alguns casos, a seleção de canal pode ser baseada em uma configuração recebida de uma estação base.
