一种上行控制信道的发送方法、装置及系统
摘要：
本发明公开了一种上行控制信道的发送方法、装置及系统。本发明方案中，对应于PDSCH资源分配的PDCCH的第一个CCE的CCE索引与UE发送HARQ－ACK包信息的PUCCH资源的PUCCH资源索引隐含映射后，在两个不同时隙传输HARQ－ACK包信息的PUCCH资源所对应的资源块RB的RB索引分别为RB1，k、RB2，k，k∈[0，N－1]，其中N为PDSCH所在载波分量的数量；选择在与第k′个载波分量上的PDSCH相对应的PUCCH资源上发送HARQ－ACK包信息，k′满足：，其中Metric(k)＝abs(RB1，k－RB2，k)，所述PUCCH资源的PUCCH资源索引为，RB索引差值最大意味着PUCCH资源在两个时隙上所对应的频率资源在频域上跨度也最大，从而可以获取更大的频率分集增益，以此来增强PUCCH的传输效率，提高整个通信系统的传输质量。
摘要（英）：

The present invention discloses a method for transmitting uplink control channel, a device and a system thereof. In the solution of the invention, after the CCE index and UE corresponding with the first CCE of PDCCH corresponding to the PDSCH resource allocation transmit the PUCCH resource index implicit mapping of PUCCH resource of HARQ-ACK package information, the RB indexes of resource block RB of PUCCH resource which transmits HARQ-ACK package information between two different time slots are respectively RB1,k and RB2,k, k, wherein k is selected from the range from 0 to N-1, and wherein N is the number of carrier component comprising PDSCH. The HARQ-ACK package information is transmitted selectively in the PUCCH resource corresponding with PDSCH on the K'-th carrier component, and k' satisfies the following relationship: k'=arg max(Metric(k)), wherein Metric(k)=abs(RB1,k-RB2,k). The PUCCH resource index of PUCCH resource is nPUCCH, k'<(1) >. The maximum of RB index difference value means the maximum span length of frequency resource corresponding with two time slots on the frequency domain, thereby a larger frequency diversity gain can be obtained thereby enhancing the transmission efficiency of PUCCH and the transmission quality of whole transmission system is increased.
