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.

Description

Background technique

[0001] In general terms, the following relates to wireless communications, and more specifically, to communications in machine-to-machine (M2M) wireless wide area networks (WANs). Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, sensor data, tracking data, and so on. These systems may be multiple-access systems capable of supporting communication with multiple users by sharing available system resources (eg, time, frequency and power). Examples of such multiple-access systems include Code Division Multiple Access (CDMA) systems, Time Division Multiple Access (TDMA) systems, Frequency Division Multiple Access (FDMA) systems and Orthogonal Frequency Division Multiple Access (OFDMA) systems.

[0002] Generally, a wireless multiple-access communication system may include multiple base stations, each base station simultaneously supporting communication ...
