Abstract: Methods, systems, and devices are described for mapping, by a UE, uplink transmissions to one or more antennas of the UE. In one aspect, a UE may receive an uplink resource allocation identifying a set of resource blocks (RBs) from a base station. The UE may map subsets of the set of RBs to one or more of a plurality of antennas of the UE and transmit one or more uplink transmissions, using the subsets of the set of resource blocks, on the one or more antennas based at least in part on the mapping. Additionally, in some aspects, the UE may determine channel characteristics or CSI associated with the downlink from the base station and base the mapping of subsets of RBs to one or more antennas of the UE on the determined channel characteristics/CSI.

Abstract translation: 描述了方法，系统和设备，用于将UE向UE的一个或多个天线映射上行链路传输。 一方面，UE可以从基站接收标识资源块（RB）集合的上行链路资源分配。 UE可以将该组RB的子集映射到UE的多个天线中的一个或多个天线，并且使用该资源块集合的子集在至少一个或多个天线上发射一个或多个上行链路传输 部分映射。 另外，在一些方面，UE可以确定与基站的下行链路相关联的信道特性或CSI，并且基于所确定的信道特性/ CSI，将RB的子集映射到UE的一个或多个天线。
