Abstract

Systems and methodologies are described that facilitate reducing battery consumption during periods of inactivity intermixed with traffic bursts in wireless communications systems. A semi-connected mode is provided that fast recognition of mobile devices upon wakeup and access while enabling mobile devices to operate in reduce power states. A mobile device operates in a semi-connected mode with all base stations in an active set of the mobile device. Moreover, mechanisms are provided to notify mobile devices of pending data while avoiding latency associated with paging channels.

Description

technical field [0001] In general, the following description relates to wireless communication, and in particular, the following description relates to a semi-connected mode of operation in a wireless communication system. Background technique [0002] Wireless communication systems are widely deployed today to provide various types of communication content such as voice, data, and so on. A typical wireless communication system may be a multiple-access system that supports communication with multiple users by sharing available system resources (eg, bandwidth, transmit 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, Orthogonal Frequency Division Multiple Access (OFDMA) systems, and so forth. [0003] Generally, a wireless multiple-access communication system can simultaneously support communication for multiple mobile de...
