Methods and systems for adaptive channel estimation/prediction filter design

A user equipment configurable for operation in a wireless network, the user equipment comprising:

• wireless circuitry comprising a receiver and a transmitter;
• a memory circuit configured to store data, including a filter lookup table, and commands;
• and
• a processor circuit configured to, upon execution of the commands, cause the user equipment to:
• receive an information message from a network serving node, the information message comprising a list of a plurality of measurement nodes in the wireless network;
• perform a plurality of measurements on signals received from network nodes in the plurality of measurement nodes;
• select a plurality of transmission nodes from the plurality of measurement nodes to form a joint transmission set based on the plurality of measurements on signals received from the network nodes;
• and
• select a filter length for each transmission node in the plurality of transmission nodes based on the filter lookup table, which associates filter lengths with measurement values for the plurality of measurements, wherein measurement values for the plurality of measurements include correlation percentage values associated with coherence times of channels between the user equipment and the plurality of transmission nodes, and the filter lookup table comprises at least:
• a low filter length value associated with a first range of coherence values, and
• a high filter length value that exceeds the low filter length value and is associated with a second range of coherence time values that exceed the first range of coherence time values.

A non-transitory computer-readable medium storing executable instructions that, when executed by one or more processors of a wireless communication device, cause the wireless communication device to:

• measure at the wireless communication device a plurality of reception values for signals received from a plurality of network nodes of a wireless network, each reception value associated with a corresponding network node;
• select a particular network node based on the reception value associated with the particular network node;
• calculate a coherence time value for a channel between the particular network node and the wireless communication device;
• and
• adjust a length of a filter associated with the particular network node based on a filter lookup table and on the calculated coherence time value,
• wherein the filter lookup table associates filter length values with coherence time values and comprises at least:
• a low filter length value associated with a first range of coherence time values, and
• a high filter length value that exceeds the low filter length value and is associated with a second range of coherence time values that exceed the first range of coherence time values.
