PEER-TO-PEER BEAMFORMING ALIGNMENT IN NEW RADIO (NR) SIDELINK (SL) MODE 2 - A simplified explanation of the abstract

This abstract first appeared for US patent application 18304665 titled 'PEER-TO-PEER BEAMFORMING ALIGNMENT IN NEW RADIO (NR) SIDELINK (SL) MODE 2

Simplified Explanation

This patent application describes a wireless communication system that supports beamforming alignment between two devices over a sidelink.

  • The system allows an initiator device to initiate a beamforming alignment procedure with a responder device over the sidelink.
  • The initiator device defines a set of subchannels, which are specific channels used for reception beam sweeping.
  • The set of subchannels is determined by a deterministic sequence, which is a predetermined order of subchannels.
  • The deterministic sequence is anchored to a direct frame number (DFN) of the sidelink frame, without the need for initial sensing.
  • The deterministic sequence can be determined based on a sequence index, the identification IDs of the devices, or a combination of both.
  • This approach reduces the number of bits needed to indicate the deterministic sequence to the responder device.
  • The use of a deterministic sequence improves the efficiency and reliability of the beamforming alignment procedure in the wireless communication system.


Original Abstract Submitted

This disclosure provides systems, methods, and devices for wireless communication that support mechanisms for sidelink beamforming alignment over a set of resources based on a deterministic sequence in a wireless communication system. In aspects, an sidelink initiator user equipment (UE) may initiate a beamforming alignment procedure with a responder UE over a the sidelink. The initiator UE may define a set of subchannels specified by a deterministic sequence. The set of subchannels may be subchannels over which the initiator UE may perform reception beam sweeping. The deterministic sequence may be anchored to a direct frame number (DFN) of the sidelink frame without initial sensing, and may be determined via a sequence index, as a function of sidelink UE identification ID(s), or a combination thereof. In this manner, the number of bits for indicating the deterministic sequence to the responder UE may be reasonable, manageable, and/or moderate.
