Method for saving power consumption of mobile station, and mobile station, base station, and access point

A mobile station, comprising:

• a first communications module, applying a first radio access technology;
• and
• a second communications module, applying a second radio access technology,
• wherein
• the first communication module receives control information from a base station through a control channel in a licensed spectrum via the first radio access technology;
• the first communication module obtains a control instruction from a corresponding resource block according to the control information, wherein when the base station and an access point employ a link manner of a non-ideal backhaul network, a time for the first communication module receiving the control information differs from a time for the first communication module receiving the control instruction by a first transmission delay time, wherein the first transmission delay time corresponds to a second transmission delay time between the base station and the access point;
• in response to receiving the control instruction by the first communications module, the first communications module wakes up the second communications module according to the control instruction by sending out a wake-up indication, and
• in response to receiving an indication frame by the second communications module from the access point, the second communications module entering a sleep mode.

A method for saving power consumption of a mobile station, applicable to a base station applying a first radio access technology, comprising:

• sending control information through a control channel in a licensed spectrum of the first radio access technology, so as to notify the mobile station to obtain a control instruction from a corresponding resource block according to the control information;
• transmitting a control instruction to a mobile station through the corresponding resource block of the control information, so as to wake up, according to the control instruction, a communications module applying a second radio access technology of the mobile station, wherein when the base station and an access point employ a link manner of a non-ideal backhaul network, a time for sending the control information differs from a time for sending the control instruction by a first transmission delay time, wherein the first transmission delay time corresponds to a second transmission delay time between the base station and the access point;
• and
• in response to receiving indication information from the access point applying the second radio access technology, determining that the communications module of the mobile station enters a sleep mode.

A base station, applying a first radio access technology, comprising:

• a transceiver having the first radio access technology, configured to transmit and receive a radio signal;
• and
• a controller, coupled to the transceiver, wherein the controller transmits control information through a control channel in a licensed spectrum of the first radio access technology, so as to notify a mobile station to obtain a control instruction from a corresponding resource block according to the control information;
• wherein the controller transmits the control instruction to the mobile station through the corresponding resource block of the control information, so as to wake up, according to the control instruction, a communications module applying a second radio access technology of the mobile station, wherein when the base station and an access point employ a link manner of a non-ideal backhaul network, a time for sending the control information differs from a time for sending the control instruction by a first transmission delay time, wherein the first transmission delay time corresponds to a second transmission delay time between the base station and the access point,
• wherein the controller determines that the communications module of the mobile station enters a sleep mode in response to receiving indication information through the transceiver from the access point applying the second radio access technology.
