Embodiment 1

[0469] An embodiment of the present invention provides a method for beam tracking, using the above Figure 5 The beam tracking information unit shown is used to set the antenna configuration of the backup beam link and enable enhanced beam tracking. In this embodiment, the beam tracking initiator receives the enhanced beam tracking training auxiliary sequence as For example, the method of beam tracking is described in detail, such as Figure 8 As shown, the specific steps include:

[0470] Step 801, the beam tracking initiator sends enhanced beam tracking information to the beam tracking responder in the BRP phase.

[0471] Wherein, the enhanced beam tracking information is in the enhanced beam tracking information unit of the MAC layer, then the beam tracking initiator sends a BRP frame including the enhanced beam tracking unit to the beam tracking responder in the BRP phase.

[0472] Specifically, the enhanced beam tracking information unit includes: Backup AWV Setting=01,...

Embodiment 2

[0485] An embodiment of the present invention provides a method for beam tracking, using the above Figure 5 The beam tracking information unit shown is used to set the antenna configuration of the backup beam link and enable enhanced beam tracking. In this embodiment, the beam tracking initiator sends the enhanced beam tracking training auxiliary sequence as For example, the method of beam tracking is described in detail, such as Figure 9 As shown, the specific steps include:

[0486] Step 901, the beam tracking responder sends a BRP frame carrying enhanced beam tracking information to the beam tracking initiator in the BRP phase.

[0487] Wherein, the enhanced beam tracking information is in the enhanced beam tracking information unit of the MAC layer, then the beam tracking initiator sends a BRP frame including the enhanced beam tracking unit to the beam tracking responder in the BRP phase.

[0488]Specifically, the enhanced beam tracking information is in the enhanced b...

Embodiment 3

[0501] An embodiment of the present invention provides a method for beam tracking, using the above Figure 4 The beam tracking information unit shown is used for setting the antenna configuration of the backup beam link and enabling enhanced beam tracking.

[0502] In this embodiment, taking the enhanced beam tracking training auxiliary sequence sent by the beam tracking responder as an example, the beam tracking method is described in detail, and the first four steps can refer to steps 801-804 in the first embodiment; however, this The difference between the embodiment and the first embodiment is that the information of whether to perform link switching is carried in the frame header of the physical layer frame, and a bit in the frame header of the physical layer frame is used to indicate whether to perform link switching, and at the same time, The antenna configuration of the current beam link updates the antenna configuration of the backup beam link as the antenna configura...

Abstract

The invention discloses a wave tracking method, a device and a system, which belongs to a communication technology field, can quickly find and in-time be swiched to a backup link from an optimal link, or be switched from the optimal link to the backup link, and effectively raise handling capacity of the system links. The wave beam tracking method comprise: a wave beam tracking initiator sends a wave beam tracking request to a wave beam tracking responder; the wave beam tracking initiator receives an enhanced wave beam tracking training auxiliary sequence sent by the wave beam tracking responder based on the enhanced wave beam tracking request; and when determaining whether needed to be swiched to the backup wave beam link based on a received detection result of the enhanced wave beam tracking training auxiliary sequence, the wave beam tracking initiator sends a first link swich information to the wave beam tracking responder.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a beam tracking method, device and system. Background technique [0002] Under the inevitable trend of increasingly tight wireless communication spectrum resources and higher data transmission rates, wireless short-distance communication technology in the 60GHz frequency band has also attracted more and more attention, and has become one of the most potential technologies in wireless communication technologies; among them, The 60GHz frequency band wireless short-distance communication technology belongs to the millimeter wave communication technology, which has huge communication capacity, and the 60GHz frequency band is a global free frequency band. Therefore, Europe, the United States, Japan and other countries have successively allocated continuous permission-free spectrum resources in the range of 57GHz-66GHz. [0003] Since the 60GHz millimeter wave is suitabl...
