FIELD OF DISCLOSURE

The present disclosure is generally related to communication for rendering artificial reality, including but not limited to reducing channel degradation in wireless communication for artificial reality.

BACKGROUND

Artificial reality such as a virtual reality (VR), an augmented reality (AR), or a mixed reality (MR) provides an immersive experience to a user. In one example, a user wearing a head wearable display (HWD) can turn the user's head, and an image of a virtual object corresponding to a location of the HWD and a gaze direction of the user can be displayed on the HWD to allow the user to feel as if the user is moving within a space of artificial reality (e.g., a VR space, an AR space, or a MR space).

Due to head movements, which are typical in artificial reality experiences, the console and HWD may leverage beamforming between active (e.g., serving) radio-frequency integrated circuits (RFICs) on the console and the HWD to maintain satisfactory link performance between the console and HWD. Beamforming may be performed by using segment level sweep (SLS), beam refinement (BRP), and/or tracking (BT) protocol(s). However, performing beamforming at a start of each system interval (e.g., an active period for beamforming and data burst followed by a relatively large sleep duration) may be costly. Furthermore, in some implementations, the HWD and/or the console may include a plurality of RFICs, some of which may be active, and some of which may be idle (e.g., inactive, or non-serving).
