Embedded control signaling for wireless systems
First Claim
1. A first radio comprising:
- a plurality of combiners each respective combiner for linearly combining at least one of a plurality of first information streams with one or more associated first control signals to provide a respective combined transmission signal wherein at least one of the one or more associated first control signals is a spread spectrum signal;
a plurality of transmitter antennas each for simultaneously transmitting at least one respective combined transmission signal; and
at least one receiver for receiving control information from a second radio wherein the control information is usable to adjust one or more parameters at the first radio to enhance or prevent degradation to at least one performance characteristic of at least one of the first radio and the second radio and wherein the control information is based upon a reception of at least one of the one or more associated first control signals at the second radio.

Abstract
Enhancement of wireless Channel Order and rank (ECHO) systems and ECHO repeater devices for enhancement of a wireless propagation channel for point to point or point to multipoint radio configurations are disclosed. The enhancement may be used for MIMO communications channels. Aspects support a richer multipath environment to increase the rank of the channel propagation matrix and/or to increase the magnitude of the coefficients of the propagation matrix between two or more radios. Such enhancement is applicable to backhaul radios in terms of increased range or in the number of supportable information streams. The installation provisioning optimization control monitoring and adaptation of such devices within a network of backhaul radios is also disclosed. Wireless links and control between IBR and ECHO devices and between ECHO devices and other ECHO devices are also disclosed.
