Wireless communication techniques employing beamforming based on spatial relationship to human tissue

An extended reality (XR) device, comprising:

• a modem configured to transmit and receive radio frequency (RF) signals;
• and
• a processor configured to control the modem and to perform a process including:
• determining a spatial relationship between a first lobe within a beam pattern and tissue of a human user of the XR device;
• selecting a direction for the beam pattern based on the spatial relationship;
• and
• transmitting the RF signals using the beam pattern in the direction.

An extended reality (XR) device, comprising:

• means for determining a spatial relationship between a side lobe or a back lobe of a beam pattern and a retina of a human user of the XR device;
• means for determining potential radiation exposure from the side lobe or the back lobe to the retina for a plurality of directions of the beam pattern;
• means for selecting a first direction of the beam pattern based on the potential radiation exposure;
• and
• means for transmitting data using the beam pattern according to the first direction in communication with a base station (BS) serving the XR device.

A non-transitory computer-readable medium having program code recorded thereon for wireless communication by a wireless communication device, the program code comprising:

• code for processing information regarding a physical position of an antenna array of the wireless communication device, information regarding beam pattern direction of the antenna array, and information regarding a position of tissues of a human user, wherein the code for processing includes code for indicating a spatial relationship between the tissues of the human user and a side lobe or a back lobe of a beam pattern for multiple directions;
• code for determining potential radiation exposure by the side lobe or the back lobe to the tissues of the human user for each of the multiple directions;
• code for selecting a first direction of the multiple directions for the side lobe or the back lobe, the first direction being selected according to at least a first constraint to maintain connectivity with a base station (BS) serving the wireless communication device and at least a second constraint to minimize radiation exposure to the tissues of the human user;
• and
• code for causing a transceiver of the wireless communication device to communicate data to the BS using the beam pattern and according to the first direction.
