Abstract: A transmission of information from a secondary to a primary node occurs in a plurality of N logical time durations on an uplink channel in a wireless network. A scheme for mapping between logical uplink control channel (PUCCH) resource blocks (RBs) and physical RBs (PRBs) used by PUCCH is described. A logical uplink control resource block index nLRB is derived by the secondary node in response to information from the primary node. The secondary node then maps the logical uplink control resource block index nLRB to a first uplink physical resource block index nPRB,1 of a plurality of uplink physical resource blocks, wherein nPRB,1=nLRB/2 if nLRB is even and nPRB,1=NPRB−ceil(nLRB/2) if nLRB is odd; wherein NPRB is the total number of the plurality of uplink physical resource blocks; and wherein ceil denotes the ceiling operation. The secondary node then transmits an uplink control information in a subframe using one of the plurality of uplink physical resource blocks indexed by nPRB,1.

Abstract translation: 信息从次级到主节点的传输在无线网络中的上行链路信道上的多个N个逻辑持续时间内发生。 描述了由PUCCH使用的逻辑上行链路控制信道（PUCCH）资源块（RB）和物理RB（PRB）之间的映射方案。 响应于来自主节点的信息，辅助节点导出逻辑上行链路控制资源块索引nLRB。 然后，辅助节点将逻辑上行链路控制资源块索引nLRB映射到多个上行链路物理资源块的第一上行链路物理资源块索引nPRB，1，其中如果nLRB为偶数，则nPRB，1 = nLRB / 2，并且nPRB，1 = NPRB-ceil（nLRB / 2）如果nLRB为奇数; 其中NPRB是多个上行物理资源块的总数; 并且其中ceil表示天花板操作。 然后，次级节点使用由nPRB，1索引的多个上行链路物理资源块中的一个，在子帧中发送上行链路控制信息。
