Abstract
Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a base station to transmit a feedback configuration to a user equipment (UE) indicating a subcarrier spacing and a length of a cyclic prefix (CP) that the UE is to use to transmit feedback associated with a second frequency band (e.g., a high frequency band) using a first frequency band (e.g., a low frequency band). The UE may monitor the second frequency band for downlink messages transmitted by the base station and transmit a feedback message accordingly using the indicated subcarrier spacing and applying a CP having the indicated length.
