Abstract

abstract embodiments of the present invention provide a method for determining a control channel search space. the method includes: determining numbers of epdcch sets used for enhanced physical downlink control channel epdcch transmission; determining, according to the numbers of the epdcch sets, location offsets of search spaces corresponding to the epdcch sets; and determining, according to the location offsets of the search spaces corresponding to the epdcch sets, the search spaces corresponding to the epdcch sets. the embodiments of the present invention further provide an apparatus for determining a control channel search space. by grouping and numbering time frequency resources of epdcchs, and determining different location offsets for different epdcch search spaces according to the numbers and different cell identities or ue identifiers, a probability of control channel search space conflict can be reduced. thereby, time frequency resources of control channels can be maximized in a case of multiple users, and communication efficiency can be improved. tradução do resumo resumo patente de invenção: "método e dispositivo para determinar espaço de busca de canal de controle" a presente invenção refere-se a um método para determinar um espaço de busca de canal de controle. o método inclui: determinar números de conjuntos de epdcch usados para a transmissão de canal de controle de enlace descendente físico melhorado epdcch; determinar, de acordo com os números dos conjuntos de epdcch, os desvios de localização de espaços de busca correspondentes aos conjuntos de epdcch; e determinar, de acordo com os desvios de localização dos espaços de busca correspondentes aos conjuntos de epdcch, os espaços de busca correspondentes aos conjuntos de epdcch. as modalidades da presente invenção fornecem adicionalmente um aparelho para determinar um espaço de busca de canal de controle. agrupando-se e numerando-se os recursos de frequência temporal de epdcchs, e determinando-se diferentes desvios de localização para diferentes espaços de busca de epdcch de acordo com os números e diferentes identidades de célula ou identificadores de ue, uma probabilidade de um conflito de espaço de busca de canal de controle pode ser reduzida. portanto, os recursos de frequência temporal de canais de controle podem ser maximizados em um caso de múltiplos usuários, e a eficiência de comunicação pode ser melhorada.
