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

摘要

A communication apparatus is provided. A first radio module communicates with a first communications device in compliance with a first protocol to provide a first wireless communications service. A second radio module communicates with a second communications device in compliance with a second protocol to provide a second wireless communications service. The first radio module further estimates time remaining for the second radio module before a next operation of the first radio module and transmits information regarding the estimated remaining time to the second radio module. The second radio module further schedules operations of the second radio module according to the information regarding the estimated remaining time received from the first radio module.

1. A communications apparatus, comprising:
a first radio module communicating with a first communications device in compliance with a first protocol to provide a first wireless communications service, wherein the first radio module further estimates time remaining for a second radio module and transmits information regarding the estimated remaining time to the second radio module; the second radio module communicating with a second communications device in compliance with a second protocol to provide a second wireless communications service, wherein the second radio module further schedules operations of the second radio module according to the received information regarding the estimated remaining time; wherein after receiving information regarding the estimated remaining time from the first radio module, the second radio module determines whether time required for the operations of the second radio module exceeds the estimated remaining time, and schedules the operations of the second radio module when the time required for operations of the second radio module does not exceed the estimated remaining time, and, wherein when the second radio module enters into a power saving (PS) mode, the second radio module estimates expected data exchange time under the power saving 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.
