Description

Technical Field

[0001] The present disclosure relates to wireless communications, and more particularly, to methods and systems for offloading ultra-wideband (UWB) configuration to narrowband (NB) advertisement messages in wireless networks. Background Art

[0002] Typically, request / response messages are used in a UWB system to establish a UWB ranging session between a first electronic device (e.g., a controller and an initiator) and a second electronic device (e.g., a controlled and a responder). The controller sends a request message to the controlled device in-band or out-of-band (OOB), and the controlled device reads the request message, uses the details provided in the request message to establish a UWB ranging session, and responds to the controller. Request and response messages facilitate the establishment of a UWB ranging session.

[0003] Typically, the request-response ranging setup is dedicated to the controller and the controlled. By using only request and response messages, the controller does not communicate the schedule for UWB transmissions to other nearby controllers. In addition, request-response messages need to be frequently exchanged every time the schedule is changed, with all configurations as part of the request / response message, which results in a large resource consumption of air transmissions.

[0004] It would therefore be desirable to address the above-mentioned or other disadvantages, or at least provide a useful alternative for optimizing a request-response ranging arrangement. Summary of the invention

[0029] The embodiments herein and their various features and advantageous details will be explained more fully with reference to the non-limiting embodiments shown in the accompanying drawings and described in detail in the following description. Descriptions of well-known components and processing techniques are omitted so as not to unnecessarily obscure the embodiments herein. In addition, the various embodiments described herein are not necessarily mutually exclusive, as some embodiments may be combined with one or more other embodiments to form new embodiments. Unless otherwise stated, the term "or" used herein refers to a non-exclusive or. The examples used herein are intended only to help understand the manner in which the embodiments herein may be practiced, and further enable those skilled in the art to practice the embodiments herein. Therefore, the embodiments should not be interpreted as limiting the scope of the embodiments herein.

[0030] As conventional in the art, embodiments can be described and illustrated according to the blocks that perform the described one or more functions. These blocks can be referred to as units or modules, etc., and these blocks are physically implemented by analog or digital circuits, such as logic gates, integrated circuits, microprocessors, microcontrollers, memory circuits, passive electronic components, active electronic components, optical components, hard-wired circuits, etc., and can be optionally driven by firmware. For example, the circuit can be embodied in one or more semiconductor chips, or embodied on substrate supports such as printed circuit boards. The circuits constituting the blocks can be implemented by dedicated hardware, or by a processor (e.g., one or more programmed microprocessors and associated circuits), or by a combination of dedicated hardware to perform some functions of the blocks and by a processor to perform other functions of the blocks. Without departing from the scope of the present disclosure, each block of the embodiment can be physically divided into two or more interactive and discrete blocks. Similarly, without departing from the scope of the present disclosure, the blocks of the embodiment can be physically combined into more complex blocks.

[0031] The accompanying drawings are used to help easily understand various technical features, and it should be understood that the embodiments presented herein are not limited by the accompanying drawings. Therefore, the present disclosure should be interpreted as extending to any changes, equivalents and substitutions in addition to those specifically set forth in the accompanying drawings. Although the terms "first", "second", etc. can be used to describe various elements in this article, these elements should not be limited by these terms. These terms are usually only used to distinguish one element from another element.

[0032] Therefore, embodiments herein disclose a method and system for offloading UWB configuration to NB announcement messages in a wireless network. The method includes a first electronic device generating a NB announcement message including the first set of UWB parameters to offload the first set of UWB parameters from a plurality of UWB parameters of the UWB configuration.

[0033] As part of the announcement on the NB channel, the scheduling related information is sent. The scheduling information helps other controllers in the vicinity to plan their UWB transmissions to avoid collisions. The announcement is either unencrypted or encrypted. Also, some parts of the announcement are unencrypted and some parts of the announcement are encrypted.

[0034] In one embodiment, the scheduling related information for other surrounding controllers is shared as part of the NB channel announcement without encryption, and other UWB parameters of the controlees specific to that controller are encrypted.

[0035] Therefore, embodiments of the present invention disclose a system for offloading UWB configuration to NB notification in a wireless network. The system includes multiple electronic devices, wherein a first electronic device among the multiple electronic devices includes a memory, a processor connected to the memory, a communicator connected to the memory and the processor, and a notification management controller connected to the memory, the processor and the communicator. The notification management controller is configured to offload the first set of UWB parameters from multiple UWB parameters of the UWB configuration by generating an NB notification message including the first set of UWB parameters.

[0036] Conventional methods and systems provide ranging by using only request and response messages. The request-response setting is dedicated to the controller and the controlled, and the controller cannot transmit its schedule to other controllers around. In addition, the request-response messages need to be frequently exchanged every time the schedule is changed, and all configurations are part of the request / response message, which introduces a lot of resource consumption for air transmission.

[0037] Unlike conventional methods and systems, the proposed method shares scheduling related information with other controllers in a NB channel announcement. The proposed method sends the NB channel announcement before the request and response message exchange. In addition, the proposed method offloads certain UWB configuration parameters from the request / response message to the NB announcement message. The proposed method encrypts the NB announcement message in a directed announcement that is read only by a second electronic device among a plurality of electronic devices.

[0038] Referring now to the drawings and more particularly to Figures 1 to 4 , wherein like reference numerals indicate corresponding features throughout the drawings, there are shown these preferred embodiments.
