Abstract
Method, apparatuses, and computer program product for overhead reduction are provided. One method may include determining a channel sparsity. The method may also include determining a shut-off ratio based on the channel sparsity ratio. In addition, the method may include providing feedback to a network node of a suggested shutoff pattern or a shut-off index from a shut-off table for reference signals, and receiving instructions from the network node to execute a shut-off pattern or a shut-off index selected by the network node. Further, the method may include executing a shut-off procedure according to the shut-off pattern or the shut-off index selected by the network node.
Claims16
A method for a mobile station, comprising:
- determining a channel sparsity ratio;
- determining a shut-off ratio based on the channel sparsity ratio;
- providing feedback to a network node of a suggested shut-off pattern or a shut-off index from a shut-off pattern table for reference signals;
- receiving instructions from the network node to execute a shut-off pattern or a shut-off index selected by the network node;
- and
- executing a shut-off function according to the shut-off pattern or the shut-off index selected by the network node.
An apparatus, comprising:
- at least one processor;
- and
- at least one memory comprising computer program code,
- the at least one memory and the computer program code are configured, with the at least one processor to cause the apparatus at least to
- determine a channel sparsity ratio;
- determine a shut-off ratio based on the channel sparsity ratio;
- provide feedback to a network node of a suggested shut-off pattern or a shut-off index for reference signals;
- receive instructions from the network node to execute a shut-off pattern or a shut-off index selected by the network node;
- and
- execute a shut-off procedure according to the shut-off pattern or the shut-off index selected by the network node.
A non-transitory computer program product encoded with instructions, which when executed by an apparatus, cause the apparatus at least to:
- determine a channel sparsity ratio;
- determine a shut-off ratio based on the channel sparsity ratio;
- provide feedback to a network node of a suggested shut-off pattern or a shut-off index for reference signals;
- receive instructions from the network node to execute a shut-off pattern or a shut-off index selected by the network node;
- and
- execute a shut-off procedure according to the shut-off pattern or the shut-off index selected by the network node.
