METHODS AND SYSTEMS FOR ADAPTIVE CHANNEL ESTIMATION/PREDICTION FILTER DESIGN

摘要

A method to adapt a set of multi-point channel estimation filters for use in wireless communications including measuring a plurality of reception values is provided. Each reception value included in the plurality of reception values associated with one of the network nodes. The method includes sorting the plurality of reception values according to magnitude and determining a select reception value. The method includes selecting a particular network node from the set of network nodes based on the reception value. The reception value is within a threshold from the select reception value. The method includes adjusting the length of a multi-point channel estimation filter associated with the particular network node. The adjusting the length is based on a lookup table and on the reception value associated with the particular network node, according to some embodiments. User equipment in a wireless network adapted for the above method is also provided.

1. A method to adapt filter lengths for a set of channel estimation filters for use in a wireless communication device, the method comprising:
by the wireless communication device:
tracking a plurality of network nodes in a joint transmission set;providing a two-dimensional circular buffer for storing reception values for signals received from the plurality of network nodes in the joint transmission set over a time window;determining a moving average of a plurality of stored reception values for a particular network node included in the joint transmission set;determining one or more transmission time intervals (TTIs) for each network node actively participating in at least a previous joint transmission set; andadapting a filter length for the particular network node in the joint transmission set based at least in part on the moving average of the plurality of stored reception values for the particular network node.
