Abstract
Certain embodiments of the present disclosure improve a robustness of some critical MAC management response massages transmitted from a base station (BS) to a mobile station (MS). In this way, a reliability of transmission can be increased and a messaging failure that results in out of sync state between the MS and the BS can be avoided.
Claims56
A method for a wireless communication system comprises:
- transmitting a first data burst using a first modulation and coding scheme (MCS);
- receiving a media access control (MAC) management request message from a mobile station;
- and
- in response to receiving the MAC management request message, transmitting a MAC management response message in a second data burst using a second MCS having a robustness that is independent of carrier-to-interference-plus-noise ratio (CINR) information of the mobile station and that is more robust than the first MCS, wherein the MAC management response message is configured to influence an idle mode, sleep mode, or registration state of the mobile station.
