Abstract
Certain embodiments of the present disclosure provide methods and systems for saving battery power in frequency division duplex (FDD) or half-duplex FDD (H-FDD) wireless networks.
Claims36
A method for wireless communications by a mobile station (MS), comprising:
- transmitting a request message to a base station (BS) to notify the BS of the MS entering the idle mode, wherein the message includes an indication of a first frequency division duplex (FDD) group of the BS;
- receiving a command message from the BS, wherein the command message includes an indication of a second FDD group of the BS;
- monitoring paging messages during a time interval of the second FDD group and powering down during a time interval of the first FDD group;
- and
- receiving a paging advertisement message in the second FDD group and sending a reply to the paging advertisement message to the base station in an uplink subframe of the second FDD group.

An apparatus for wireless communications by a mobile station (MS), comprising:
- a processor;
- and
- memory storing instructions that are executable by the processor to:
- transmit a request message to a base station (BS) to notify the BS of the MS entering the idle mode, wherein the message includes an indication of a first frequency division duplex (FDD) group of the BS,
- receive a command message from the BS, wherein the command message includes an indication of a second FDD group of the BS,
- monitoring paging messages during a time interval of the second FDD group and powering down during a time interval of the first FDD group, and
- receive a paging advertisement message in the second FDD group and sending a reply to the paging advertisement message to the base station in an uplink subframe of the second FDD group.
