Abstract
A first communication device receives a first signal, the first signal being transmitted by a second communication device using a first spatial-domain transmit filter; determines, based on the first signal, a Line-of-Sight characteristic associated with the first spatial-domain transmit filter, and transmits a first control message to the second communication device, the first control message indicating the Line-of-Sight characteristic associated with the first spatial-domain transmit filter.
Claims19
A first communication device, comprising:
- a processor;
- and
- a non-transitory computer-readable storage medium coupled to the processor and storing a program executable by the processor, the program including instructions to:
- receive a first signal, the first signal being transmitted by a second communication device using a first spatial-domain transmit filter;
- determine, based on the first signal, a Line-of-Sight characteristic associated with the first spatial-domain transmit filter, wherein the Line-of-Sight characteristic indicates whether a propagation channel associated with a transmit beam resulting from the first spatial-domain transmit filter corresponds to a Line-of-Sight path or a non-Line-of-Sight path between the second communication device and the first communication device, and different spatial-domain transmit filters correspond to the Line-of-Sight path and the non-Line-of-Sight path;
- and
- transmit a first control message to the second communication device, the first control message indicating the Line-of-Sight characteristic associated with the first spatial-domain transmit filter.

A second communication device, comprising:
- a processor;
- and
- a non-transitory computer-readable storage medium coupled to the processor and storing a program for execution by the processor, the program including instructions to:
- transmit a first signal using a first spatial-domain transmit filter to a first communication device;
- receive a first control message from the first communication device in response to the transmission of the first signal, wherein the first control message indicates a Line-of-Sight characteristic associated with the first spatial-domain transmit filter, wherein the Line-of-Sight characteristic indicates whether a propagation channel associated with a transmit beam resulting from the first spatial-domain transmit filter corresponds to a Line-of-Sight path or a non-Line-of-Sight path between the second communication device and the first communication device, and different spatial-domain transmit filters correspond to the Line-of-Sight path and the non-Line-of-Sight path;
- select a second spatial-domain transmit filter based on the indicated Line-of-Sight characteristic associated with the first spatial-domain transmit filter;
- and
- transmit a second signal to the first communication device using the selected second spatial-domain transmit filter.

- receiving, by a first communications device from a second communication device, a first signal transmitted using a first spatial-domain transmit filter;
- determining, by the first communications device based on the first signal, a Line-of-Sight characteristic associated with the first spatial-domain transmit filter, wherein the Line-of-Sight characteristic indicates whether a propagation channel associated with a transmit beam resulting from the first spatial-domain transmit filter corresponds to a Line-of-Sight path or a non-Line-of-Sight path between the second communication device and the first communication device, and different spatial-domain transmit filters correspond to the Line-of-Sight path and the non-Line-of-Sight path;
- and
- transmitting, by the first communications device, a first control message to the second communication device, the first control message indicating the Line-of-Sight characteristic associated with the first spatial-domain transmit filter.
