Embodiment Construction

[0029]A description of preferred embodiments of the invention follows.

[0030] 1 is a block diagram illustrating a wireless communication system that supports transmission of data information over multiple assigned communication channels in accordance with certain aspects of the present invention. As in many radio communication systems, users compete for wireless bandwidth allocation. Accordingly, it is desirable that wireless communication 10 be optimized for data throughput and, in certain applications, high speed bursts of data throughput.

[0031] Certain aspects of the present invention are based on the recognition that the power output of a field unit transmitting over a wireless channel can be controlled such that it causes minimal interference to other field units using the same common radio airspace. Specifically, the power output level of the transmitting field unit is set as low as possible so that it does not interfere with other field units attempting to communi...

Abstract

In a reverse link (50) of a wireless CDMA communication system (10), a method of maintaining an idling mode connection between a field unit (24) and a base transceiver station (18) is provided using various techniques to maintain the idle mode connection at a reduced power level. A preferred embodiment computes a time slot or frame offset based on modulo function using a field unit identifier (62) in order to distribute field unit maintenance transmissions among available slots or offsets. An alternate embodiment detects explicit signaling states changes at the physical layer and causes power target changes. A further embodiment transmits maintenance data during predetermined time intervals, coordinated between the field units (24) and BTS (base transceiver station) (18), allowing power levels to be adjusted accordingly.

Description

[0001] This application is a divisional application of the Chinese invention patent application with the application number 03805565.1, the application date is January 8, 2003, and the invention title is "Maintaining the Hold Channel in the Reverse Link of the Wireless Communication System". technical field [0002] The present application relates to maintaining a hold channel in a reverse link of a wireless communication system. Background technique [0003] In point-to-multipoint wireless communication systems, a number of wireless channels provide connections between remote (mobile) access or field units and a central location (eg, a base station or access point). In a Code Division Multiple Access (CDMA) system, many different channels can be transmitted on a single radio frequency carrier by applying a different code to each signal. However, even in a CDMA system, the demand for access to channels is so great that the base station must allocate and switch channels among...
