Abstract
Various examples of the disclosure pertain to multi-device transmission via a coverage enhancing device such as a reconfigurable reflective device. Spatial filters are used at the coverage enhancing device that support a count of input spatial directions that is different than a count of output spatial directions.
Claims19
A method of operating a coverage enhancing device comprising multiple antenna elements, each one of the multiple antenna elements being configurable to apply a phase shift to an incident signal,
- wherein the method comprises:
- obtaining a message for configuring the coverage enhancing device to contemporaneously reflect the incident signal incident along an input spatial direction into multiple output spatial directions, the message indicating a power distribution ratio between output signals reflected along different ones of the multiple output spatial directions, and
- upon receiving the message and in accordance with the power distribution ratio, determining, by the coverage enhancing device, phase shifts based on the power distribution ratio included in the message and configuring the multiple antenna elements to apply the phase shifts to reflect the incident signal into the multiple output spatial directions.
A method of controlling a coverage enhancing device comprising multiple antenna elements, each one of the multiple antenna elements being configurable to apply a phase shift to an incident signal, wherein the method comprises:
- providing, to the coverage enhancing device, a message for causing the coverage enhancement device to determine phase shifts based on a power distribution ratio included in the message and to reflect, based on the phase shifts, the incident signal incident along an input spatial direction into multiple output spatial directions, the power distribution ratio being a power distribution between output signals reflected along different ones of the multiple output spatial directions.
A coverage enhancing device comprises a processor and multiple antenna elements, each one of the multiple antenna elements being configurable to apply a phase shift to an incident signal, wherein the processor is configured to:
- obtain a message for configuring the coverage enhancing device to contemporaneously reflect the incident signal incident along an input spatial direction into multiple output spatial directions, the message indicating a power distribution ratio between output signals reflected along different ones of the multiple output spatial directions, and
- upon receiving the message and in accordance with the power distribution ratio, determine, by the coverage enhancing device, phase shifts based on the power distribution ratio included in the message and configure the multiple antenna elements to apply the phase shifts to reflect the incident signal into the multiple output spatial directions.
