Abstract: Methods, systems, and devices are described for managing wireless communications in a machine-to-machine (M2M) wireless Wide Area Network (WAN). A traffic slot map is generated. The traffic slot map identifies one or more first time slots and one or more second time slots. First data is transmitted during the one or more first time slots at a first data rate. Second data is transmitted during the one or more second time slots at a second data rate. The traffic slot map is broadcasted to one or more M2M devices during a traffic slot of a first forward link frame at a beginning of a traffic channel cycle.

Abstract: A method for decoding a speech signal is described. The method includes obtaining a packet. The method also includes obtaining a previous lag value. The method further includes limiting the previous lag value if the previous lag value is greater than a maximum lag threshold. The method additionally includes disallowing an adjustment to a number of synthesized peaks if a combination of the number of synthesized peaks and an estimated number of peaks is not valid.

Abstract: Described are a system and method for correcting a receiver frequency at a receiver to enhance detection of arrival of a wirelessly transmitted message. In particular, a frequency offset between receiver frequency and a carrier frequency may be estimated based, at least in part, on an autocorrelation of a bit sequence in a received message.

Abstract: Methods, systems, and devices are described for managing wireless communications in a machine-to-machine (M2M) wireless Wide Area Network (WAN). An operating frequency band of the M2M wireless WAN is divided into at least a first frequency channel and a second frequency channel. The first and second frequency channels being used for communications on a reverse link. A first rise over thermal (RoT) threshold is set for the first frequency channel. A second RoT threshold is set for the second frequency channel. The second RoT threshold is lower than the first RoT threshold.

Abstract: Methods, systems, and devices are described for managing wireless communications in a machine-to-machine (M2M) wireless Wide Area Network (WAN). A packet is decoded and demodulated by an M2M device that is received during a time slot of a physical layer forward link frame in the M2M wireless WAN. The packet is transmitted by a base station. The M2M device enters a sleep state before a physical layer acknowledgment (ACK) message is transmitted to the base station to indicate receipt of the packet.
