US 2021/0345361 A1 · SENSOR CONTROLLER AND PEN

Abstract

A change of a resource allocation scheme in a multi-pen supporting electronic apparatus can be made in a shorter period of time than in the prior art. A sensor controller 50 assigns communication resources to one or more pens 2, respectively, and detects a position of each of the one or more pens 2 on the basis of a downlink signal DS received from each of the one or more pens 2 using the assigned communication resources. When changing a resource allocation scheme, which indicates a structure of the communication resources or a method of using the communication resources, the sensor controller 50 broadcasts information indicating a new resource allocation scheme to the one or more pens 2.

Dependent claims

A sensor controller comprising:

a memory;
and
a processor configured to assign communication resources to one or more pens,
respectively, and to detect a position of each of the one or more pens based on a downlink signal received from each of the one or more pens using the assigned communication resources,
wherein
when changing a resource allocation scheme indicating a structure of the communication resources or a method of using the communication resources, the sensor controller broadcasts information indicating a new resource allocation scheme to the one or more pens.

3 more elements

A pen comprising:

a memory;
and
a processor configured to receive a resource allocation scheme indicating a structure of communication resources or a method of using the communication resources from a sensor controller and to transmit a downlink signal according to the resource allocation scheme,
wherein
the pen is configured to receive identification information indicating assignment of the communication resources from the sensor controller and to transmit the downlink signal by using the communication resources assigned by the identification information, and
when the pen receives a new resource allocation scheme from the sensor controller, the pen continues to use the communication resources assigned by the identification information to transmit the downlink signal according to the new resource allocation scheme.
