1. A method of wireless communication operable at a scheduling entity, comprising:communicating with a plurality of scheduled entities including a first scheduled entity and a second scheduled entity through a downlink (DL) channel;
configuring the first scheduled entity to utilize a first subframe structure for estimating the DL channel; and
configuring the second scheduled entity to utilize a second subframe structure, different from the first subframe structure, for estimating the DL channel when the second scheduled entity is located near or at a cell edge of the scheduling entity,
wherein the second subframe structure is configured to provide more DL resources corresponding to reference signals and data signals than the first subframe structure, for estimating the DL channel.
