将循环移位映射到用于ACK/NACK资源分配的信道索引
摘要：
从网络的角度出发，发送对多个用户设备UE许可上行链路资源的上行链路资源分配(PDCCH)，并且该分配具有用于所述多个UE中的每一个的循环移位CS的指示。许可的上行链路资源被根据用于所述多个UE中的每个的指示CS映射到下行链路资源(PHICH)。所述映射使得对于在单个MU‑MIMO上行链路资源分配许可中被分配相同上行链路资源的预定数目的UE而言，映射到相邻下行链路资源的所述预定数目的UE中的每一对相对于彼此表现出优化的CS。网络还在相应的映射的下行链路资源上向相应的多个UE中的每一个发送关于接收到的数据(在PUSCH上)的指示(ACK/NACK)。详述了用于网络和UE侧实现的装置、方法和计算机程序。
摘要（英）：

From the network perspective, an uplink resource allocation (PDCCH) is sent that grants an uplink resource to a plurality of user equipments UEs, and the allocation has an indication of a cyclic shift CS for each of the plurality of UEs. The granted uplink resource is mapped to a downlink resource (PHICH) in dependence on the indicated CS for each of the plurality of UEs. The mapping is such that for a predetermined number of UEs being allocated a same uplink resource in a single MU-MIMO uplink resource allocation grant, each pair of said predetermined number of UEs which map to an adjacent downlink resource exhibit an optimized CS relative to one another. The network sends to each of the respective plurality of UEs on the respective mapped downlink resource an indication (ACK/NACK) about data received (on a PUSCH).
