US 10,476,635 B2 · Adaptive interleaver for wireless communication systems

Abstract

The described technology is generally directed towards adaptive interleaving in network communications systems based on one or more conditions with respect to user equipment. When conditions such as the speed of the user equipment indicate that performance can be increased by interleaving the data traffic, data is transmitted to the user equipment using an adaptive interleaver in the coding chain of MIMO systems. The adaptive interleaver is not used when conditions indicate performance is unlikely to improve. Adaptive interleaving may be performed in the frequency domain, in the frequency and time domain, or the frequency time and space domain. Multiple interleavers with different interleaving patterns may be used in the frequency domain and in the frequency and time domain. Adaptive interleaving may be based on one or more various criteria corresponding to the condition data received from the user equipment.

Dependent claims

A radio network device, comprising:

a processor;
and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations, the operations comprising:
determining that interleaving of data communications is likely to improve data communication performance between the radio network device and a user equipment;
in response to the determining,
communicating first adaptive interleaving information to the user equipment that instructs the user equipment to turn on adaptive interleaving at the user equipment, and
communicating interleaved communications data between the network device and the user equipment;
making a subsequent determination, after the determining, that the interleaving is no longer likely to improve the data communication performance;
and
in response to the making the subsequent determination,
communicating second adaptive interleaving information to the user equipment that instructs the user equipment to turn off the adaptive interleaving at the user equipment, and
communicating non-interleaved communications data to the user equipment.

A method, comprising:

determining, by a radio network device of a wireless network and comprising a processor, that interleaving satisfies a threshold probability to increase a communication performance between the radio network device and a user equipment;
in response to the determining, communicating, by the radio network device, adaptive interleaving information facilitating using adaptive interleaving at the user equipment;
