Abstract

Methods, systems, and devices are described for adjusting at least one channel parameter based on accessed historical channel information associated with mobility patterns of a mobile device. In some examples, a mobile device or a base station may access historical channel information associated with mobility patterns of the mobile device or another mobile device. The mobility patterns may include information relative to a particular time and location of a mobile device, a previously traveled route by a mobile device, etc. Based on the historical channel information associated with the mobility patterns, the mobile device or the base station may adjust a channel parameter to improve communication performance across the particular channel.

recognizing that a mobile device is traveling along a previously travelled path;

accessing historical channel information associated with historical mobility patterns of the mobile device, wherein the historical mobility patterns comprise patterns of another mobile device previously traveling the path;

predicting a current channel condition based at least in part on the accessed historical channel information;

determining a level of accuracy of the predicted current channel condition;

measuring a current channel condition if the determined level of accuracy satisfies a threshold; and

adjusting a modulation and coding scheme (MCS) parameter of the mobile device based at least in part on the accessed historical channel information associated with the historical mobility patterns of the mobile device, the predicted current channel condition, and the measured current channel condition.

2. The method of claim 1, further comprising:

predicting a variance in a channel condition based at least in part on the accessed historical channel information;

wherein adjusting the MCS parameter is based at least in part on the predicted variance in the channel condition.

measuring a current channel condition;

wherein adjusting the MCS parameter is based at least in part on the measured current channel condition and the accessed historical channel information.

4. The method of claim 1, wherein the historical channel information comprises at least one of channel quality information (CQI), precoding matrix information (PMI), and rank information (RI).

5. The method of claim 1, wherein the historical mobility patterns of the mobile device further comprise at least one of a time value associated with at least one geographic location, a current cell identification (ID), or at least one other cell ID in a known physical route of the mobile device.

6. The method of claim 5, wherein the historical channel information associated with the historical mobility patterns of the mobile device comprises at least one channel condition associated with the at least one of the time value associated with the at least one geographic location, the current cell ID, or the at least one other cell ID in the known physical route of the mobile device.

7. The method of claim 1, wherein the historical mobility patterns of the mobile device further comprise a physical route previously travelled by the mobile device.

8. The method of claim 1, further comprising:
