Methods and Apparatus For Device Scheduling

摘要

Systems and techniques for crosstalk estimation. One or more user devices feed back preceding matrix indicator rank information to one or more base stations, which generated channel state information reference sources, at least one of which includes weightings based on the preceding matrix indicator rank information. One or more user devices estimates channel information based on active preceding matrix indicator information received by the base station from at least one user device. One or more user devices computes channel estimates for a desired transmission channel and one or more other potential transmission channels associated with other user devices and performs crosstalk estimation for the estimated channels. Crosstalk estimation information is fed back to a base station, which performs scheduling based at least in part on the crosstalk estimation from the one or more user devices.

1. An apparatus comprising:
at least one processor; memory storing computer program code; wherein the memory storing the computer program code is configured to, with the at least one processor, cause the apparatus to at least: control a user device operating in a wireless communications network to monitor at least first and second channel state information reference signal resources, wherein at least one of the channel state information reference signal resources is weighted by a transmit weight chosen from an active precoding matrix indicator rank indicator set; control the user device to compute channel estimation to estimate a first channel, and determine single user multiple-input multiple-output channel quality information, based on the first channel state information reference signal resource; control the user device to perform channel estimation to estimate a second channel, wherein the second channel comprises at least one precoded downlink multiple-input multiple-output channel for which transmit weights chosen from the active precoding matrix indicator rank indicator set are used for precoding; control the user device to compute crosstalk between a desired and a simultaneously scheduled transmission, on the estimated first and second channel, wherein crosstalk estimation is based at least in part on at least one interfering transmit weight used for channel state information reference signal precoding; and control the user device to feed back the computed crosstalk to a base station.
