Embodiment Construction

[0021] The techniques described herein may be used in various wireless communication networks. The terms "network" and "system" are often used interchangeably. For example, these techniques can be used in Wireless Wide Area Networks (WWAN) and cellular networks such as CDMA networks, TDMA networks, FDMA networks, OFDMA networks, and the like. A CDMA network may implement a radio technology such as Wideband-CDMA (W-CDMA), cdma2000, and so on. cdma2000 covers IS-2000, IS-95 and IS-856 standards. A TDMA network may implement a wireless technology such as Global System for Mobile Communications (GSM), WiMax, and so on. These various wireless technologies and standards are well known in the art. W-CDMA and GSM are described in documents from an organization named "3rd Generation Partnership Project" (3GPP). cdma2000 is described in documents from an organization named "3rd Generation Partnership Project 2" (3GPP2). WiMax is described in the IEEE 802.16 document from an organiz...

Abstract

Techniques for extending coverage of a wireless communication network (e.g., a cellular network) to indoor and other locations are described. A wireless device may communicate with a base station in awireless network via downlink and uplink frequency channels in a licensed frequency band using frequency division duplexing (FDD). The wireless device may communicate with a piconet base station (PBS) in a pico network (piconet) via the uplink frequency channel using time division duplexing (TDD). The PBS may communicate with the wireless device on the uplink frequency channel and may exchange data with the wireless network via a wireline communication link. The PBS may forward data received from the wireless device to the wireless network and may also forward data received from the wirelessnetwork for the wireless device to the wireless device. The PBS may receive paging messages from the wireless network for the wireless device and may forward the paging messages to the wireless device.

Description

technical field [0001] Generally speaking, the present invention relates to communication, and in particular, the present invention relates to techniques for extending the coverage of wireless communication networks. Background technique [0002] Wireless communication systems are widely deployed to provide various communication services such as voice, video, packet data, messaging, broadcast, and so on. These wireless networks may be multiple-access networks capable of supporting multiple users by sharing available network resources. Examples of such multiple-access networking systems include Code Division Multiple Access (CDMA) networks, Time Division Multiple Access (TDMA) networks, Frequency Division Multiple Access (FDMA) networks, Orthogonal FDMA (OFDMA) networks, and the like. [0003] In a wireless network, a wireless device (eg, a handset) can communicate with a base station via downlinks and uplinks. The downlink (or forward link) refers to the communication link...
