CHANNEL STATE INFORMATION COMPUTATION USING A CONTROL RESOURCE ASSUMPTION

摘要

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adjust control overhead assumptions when reporting a channel state indictor (CSI). A base station may configure resource block (RB) sets for the UE by radio resource control (RRC) signaling. The UE may assume that the RB sets as configured are assigned for control information. When the UE reports wideband CSI, it may be assumed that the resources for an RB set are not available for data transmission. Any portion of a band configured for the UE overlapping with an RB set may be considered unavailable for data transmission. The UE may then calculate CSI based on the updated control overhead assumption. In other examples, the UE may make a worst-case assumption for control overhead. In some cases, the UE may assume there is no control overhead.
