Method for performing transmission and reception control of wireless communications device with communications control circuits corresponding to different types of communications services, and associated wireless communications device

A method for performing transmission and reception control of a wireless communications device, the wireless communications device comprising a first communications control circuit and a second communications control circuit, the first communications control circuit communicating with a first communications device in compliance with a first protocol to provide a first wireless communications service and the second communications control circuit communicating with a second communications device in compliance with a second protocol to provide a second wireless communications service, the method comprising:

• utilizing the first communications control circuit to determine at least one indication regarding the first communications control circuit, for being sent to the second communications control circuit;
• utilizing the second communications control circuit to receive the at least one indication from the first communications control circuit, for indicating at least one behavior of the first communications control circuit;
• and
• utilizing the second communications control circuit to determine transmission power of the second communications control circuit at least according to whether multiple conditions related to the first communications control circuit are met, for controlling respective transmission power levels of multiple packets from the second communications control circuit to the second communications device in a per-packet manner, wherein the multiple conditions comprise at least one condition which is dependent on the at least one indication;
• wherein the at least one indication comprises a first estimated remaining time indication, for indicating estimated time of a remaining window, the estimated time being time remaining for the second communications control circuit, before a next receiving operation of the first communications control circuit, wherein the multiple conditions comprise a first condition which is dependent on the first estimated remaining time indication.
