Abstract
Certain aspects of the present disclosure provide techniques for determining a spatial direction of a beam for retransmitting a wireless signal. A method that may be performed by a repeater includes receiving, at the repeater, a signal transmitted by a first node, the signal carrying data intended to be received by a second node. The method may also include determining, by the repeater, a beam direction for retransmitting the received signal to the second node, the beam direction determined based on an object detection process performed by the repeater. The method may also include transmitting, by the repeater to the second node, an amplified retransmission of the received signal using a beam having the determined beam direction.

A method of determining beam direction for repeating a signal, the method comprising:
- receiving, at a repeater using a first set of one or more antenna elements over a first frequency band, a signal transmitted by a first node, the signal carrying data intended to be received by a second node;
- determining, by the repeater, a beam direction for retransmitting the received signal to the second node, the beam direction determined periodically based on an object detection process performed by the repeater using a transmit processor of the repeater and a second set of one or more antenna elements and over a second frequency band that is different from the first frequency band, the object detection process performed when a power level of signaling transmitted over the first frequency band is below a threshold power level;
- and
- transmitting, by the repeater using the first set of one or more antenna elements to the second node over the first frequency band, an amplified retransmission of the received signal generated via the transmit processor of the repeater using a beam having the determined beam direction.
A repeater configured to determine a beam direction for repeating a signal, comprising:
- a memory comprising instructions;
- and
- one or more processors configured, individually or in any combination, to execute the instructions and cause the repeater to:
- receive a signal using a first set of one or more antenna elements over a first frequency band that is transmitted by a first node, the signal carrying data intended to be received by a second node;
- determine a beam direction for retransmitting the received signal to the second node, the beam direction determined periodically based on an object detection process performed by the repeater using a transmit processor of the repeater and a second set of one or more antenna elements and over a second frequency band that is different from the first frequency band, the object detection process performed when a power level of signaling transmitted over the first frequency band is below a threshold power level;
- and
- transmit, using the first set of one or more antenna elements to the second node over the first frequency band, an amplified retransmission of the received signal generated via the transmit processor of the repeater using a beam having the determined beam direction.
An apparatus for wireless communication, comprising:
- means for receiving using a first set of one or more antenna elements a signal over a first frequency band that is transmitted by a first node, the signal carrying data intended to be received by a second node;
- means for determining a beam direction for retransmitting the received signal to the second node, the beam direction determined periodically based on an object detection process performed by the apparatus using a transmit processor of the apparatus and a second set of one or more antenna elements and over a second frequency band that is different from the first frequency band, the object detection process performed when a power level of signaling transmitted over the first frequency band is below a threshold power level;
- and
- means for transmitting, using the first set of one or more antenna elements to the second node over the first frequency band, an amplified retransmission of the received signal generated via the transmit processor of the apparatus using a beam having the determined beam direction.
A non-transitory computer-readable storage medium that stores instructions that when executed by one or more processors of a repeater cause the repeater to perform a method of determining beam direction for repeating a signal comprising:
- receiving using a first set of one or more antenna elements a signal over a first frequency band that is transmitted by a first node, the signal carrying data intended to be received by a second node;
- determining a beam direction for retransmitting the received signal to the second node, the beam direction determined periodically based on an object detection process performed by the repeater using a transmit processor of the repeater and a second set of one or more antenna elements and over a second frequency band that is different from the first frequency band, the object detection process performed when a power level of signaling transmitted over the first frequency band is below a threshold power level;
- and
- transmitting, using the first set of one or more antenna elements to the second node over the first frequency band, an amplified retransmission of the received signal generated via the transmit processor of the repeater using a beam having the determined beam direction.
