Method and apparatus that facilitates interference reduction in wireless systems

摘要

Techniques for managing interference in a wireless communication system are disclosed. In one aspect, an estimated interference associated with data transmission over a plurality of subcarriers on an uplink is determined The estimated interference may relate to intermodulation products associated with a parallel transmission over the plurality of subcarriers. Based at least partly on the estimated interference, data received on the downlink can be processed, and subcarriers can be selected for data transmission on the uplink. Additionally, resources can be assigned to a wireless device according to the estimated interference.

主权项

1. A method of wireless communication, comprising:
determining an estimated interference associated with a data transmission over a plurality of subcarriers on an uplink; transmitting a set of information relating to the estimated interference to a base station, wherein the set of information comprises frequency locations of intermodulation products associated with the plurality of subcarriers; and processing data received over at least one subcarrier on a downlink based at least in part on the estimated interference, wherein processing data received over the at least one subcarrier comprises zeroing a log-likelihood ratio (LLR) for modulation symbols of the at least one subcarrier.
