Methods for Scheduling Channel Activities for Multiple Radio Access Technologies in a Communications Apparatus and Communications Apparatuses Utilizing the Same
First Claim
1. A communications apparatus with multiple radio access technologies (RATs), comprising:
- an antenna;
a first RAT module, with a first communications interface conforming to a first wireless communications protocol and transceiving radio frequency (RF) signals in a first cellular network through the antenna;
a second RAT module, with a second communications interface conforming to a second wireless communications protocol, which is different from the first wireless communications protocol, and transceiving RF signals in a second cellular network through the antenna; and
an arbiter, receiving a first request from the first RAT module, requesting permission to use the antenna for a first channel activity, receiving a second request from the second RAT module, requesting permission to use the antenna for a second channel activity, obtaining a priority configuration for the first channel activity versus the second channel activity when the second channel activity collides with the first channel activity, and responding to one of the first and second RAT modules with an acknowledgement message and to the other of the first and second RAT modules with a rejection message based on the obtained priority configuration.

Abstract
An communications apparatus with multiple radio access technologies (RATs) is provided. A first RAT module transceives radio frequency (RF) signals in a first cellular network through the antenna. A second RAT module transceives RF signals in a second cellular network through the antenna. An arbiter receives a first and a second request from the first and second RAT module requesting permission to use the antenna for a first and a second channel activity, obtains a priority configuration for the first channel activity versus the second channel activity when the second channel activity collides with the first channel activity, and responds to one of the first and second RAT modules with an acknowledgement message and to the other of the first and second RAT modules with a rejection message based on the obtained priority configuration.

8. A method for scheduling channel activities for multiple radio access technologies (RATs) in a communications apparatus comprising an antenna, an arbiter and at least a first RAT module and a second RAT module sharing the antenna to perform corresponding channel activities, comprising:
-
receiving, by the arbiter, a request for requesting permission to use the antenna for a first channel activity for the first RAT module; obtaining, by the arbiter, a priority configuration for the first channel activity versus a forthcoming second channel activity when the first channel activity collides with the forthcoming second channel activity to be performed by the second RAT module; and responding, by the arbiter, to the first RAT module by sending an acknowledgement message or a rejection message to the first RAT module based on the obtained priority configuration to indicate whether the request has been granted. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)
