Transmitter and receiver tracking techniques for user devices in a MIMO network

摘要

A technique includes (i) receiving a first pilot signal from a base station via a receiver of a client device, or (ii) transmitting a second pilot signal from the client device to the base station via a transmitter of the client device. First time differences and signal quality values for N samples of N respective packets in the first pilot signal are determined. Second time differences and signal quality values are received via the receiver. The second time differences and signal quality values are generated for M samples of M respective packets in the second pilot signal. An offset value is determined based on (i) the first time differences and signal quality values, or (ii) the second time differences and signal quality values. Activation or deactivation times of the receiver or the transmitter or transmission times of the transmitter are adjusted based on the offset value.

1. A computer-implemented method comprising:
transmitting, by a client device, a pilot signal to a base station; receiving, by the client device from the base station, a time difference for the pilot signal and a signal quality value for the pilot signal; comparing, by the client device, the time difference to a preselected value; in response to the comparison, generating, by the client device, a complex number based on the time difference; determining, by at least one selected from the group consisting of a physical layer device (PHY) of the client device and a medium access controller (MAC) of the client device, an offset value based on the complex number and the signal quality value, wherein the offset value comprises a time value; and adjusting, by at least one selected from the group consisting of the PHY of the client device and the MAC of the client device, based on the offset value, at least one selected from the group consisting of a transmission time of a transmitter of the client device, an activation time of the transmitter, and a deactivation time of the transmitter.
