配置增强的物理混合自动重传指示信道的方法
摘要：
本发明提供了配置增强的物理混合自动重传指示信道(EPHICH)的方法，其中，在PDSCH之中复用EPHICH。优选地，(I)EPHICH被复用于增强的物理下行控制信道(EPDCCH)的公共搜索空间(CSS)的物理资源块对中，或(II)被复用于用于传输下行数据的物理资源块对中，或(III)被复用于EPDCCH的用户设备特定搜索空间(USS)的物理资源块对中。优选地，基站和用户设备根据上行传输的资源位置，基于给定算法，计算EPHICH的资源集合中的混合自动重传指示的编号，并在该编号的混合自动重传指示所对应的资源位置上发送或接收该混合自动重传指示，省去了使用单独的指示符来指示该上行传输。
摘要（英）：

The invention provides a method for configuring an enhanced physical hybrid automatic retransmission indication channel (EPHICH). The EPHICH is multiplexed in a PDSCH. Preferably, (I) the EPHICH is multiplexed in a physical resource block pair of a common search space (CSS) of an enhanced physical downlink control channel (EPDCCH), or (II) the EPHICH is multiplexed in the physical resource block pair used for transmitting downlink data, or (III) the EPHICH is multiplexed in the physical resource block pair of a user equipment specific search space (USS) of the EPDCCH. Preferably, a base station and user equipment calculate the number of a hybrid automatic retransmission instruction in a resource set of the EPHICH according to the resource position of uplink transmission on the basis of the preset algorithm, and the hybrid automatic retransmission instruction is transmitted or received at the resource position corresponding to the hybrid automatic retransmission instruction of the number so that use of an independent indicator for indicating uplink transmission is saved.
