Methods for coordinating transmission and reception operations of radio modules in a communications apparatus and communication apparatuses utilizing the same

摘要

A method for coordinating transmission and reception operations of a first and a second radio module in a communications apparatus, the first radio module communicating with a first communications device in a first protocol to provide a first wireless communications service and the second radio module communicating with a second communications device in a second protocol to provide a second wireless communications service. The method includes estimating, by the first radio module, time remaining for the second radio module; receiving, by the second radio module, information regarding the estimated remaining time from the first radio module; determining, by the second radio module, whether time required for the operations of the second radio module exceeds the estimated remaining time; and scheduling, by the second radio module, operations of the second radio module according to the information regarding the estimated remaining time received from the first radio module.

1. A method for coordinating transmission and reception operations of at least a first and a second radio module in a communications apparatus, the first radio module communicating with a first communications device in compliance with a first protocol to provide a first wireless communications service and the second radio module communicating with a second communications device in compliance with a second protocol to provide a second wireless communications service, comprising:
estimating, by the first radio module, time remaining for the second radio module; receiving, by the second radio module, information regarding the estimated remaining time from the first radio module; determining, by the second radio module, whether time required for the operations of the second radio module exceeds the estimated remaining time; scheduling, by the second radio module, operations of the second radio module according to the information regarding the estimated remaining time received from the first radio module; wherein scheduling the operations of the second radio module, by the second radio module, when the time required for the operations of the second radio module does not exceed the estimated remaining time, and, wherein the scheduling step further comprises estimating expected data exchange time under a power saving (PS) mode according to an expected data rate used by the second communications device to transmit data to the second radio module after receiving the information regarding the estimated remaining time from the first radio module when the second radio module enters into the power saving mode.
