Embodiment Construction

[0028] The present invention provides a method for supporting real-time duplex packet communication. More specifically, the present invention proposes a method of reducing transmission overhead in packet communications. To implement the present invention, for example, packet communications can support various applications and protocols, such as IP and Ethernet, each with specific header and payload structures.

[0029] refer to figure 1, describes an embodiment of the present invention. More specifically, a block diagram 10 of real-time duplex communication of data packets is shown. Here, the first and second wireless units, 20 and 40, can transmit data packets supporting real-time duplex services to each other through a base station (not shown). When in the inactive state 35, the first wireless unit 20 may transmit channel quality information to a base station (not shown). Similarly, the second wireless unit 40 can transmit channel quality information when in the inactive...

Abstract

A method of data packet communication. The method includes the step of transmitting CQI in response to an inactive state. The step of transmitting CQI may include receiving an incoming signal associated with one or more real time duplex services, such as voice over IP ('VoIP'), gaming and / or two-way video applications, for example. Thereafter, the method includes the step of pausing the transmission of CQI in response to a break period in the inactive state. The break period may be initiated by transmitting an outgoing signal associated with at least one real time duplex service, such as voice over IP ('VoIP'), gaming and / or two-way video applications, for example. Moreover, the step of pausing may include receiving a do-not-transmit signal to initiate the break period.

Description

technical field [0001] This invention relates to telecommunications, and more particularly to wireless communications. Background technique [0002] Wireless communication systems provide wireless service to a large number of wireless or mobile units within a certain geographic area. The geographic area supported by a wireless communication system is spatially divided into distinct areas, often referred to as "cells." Each cell, ideally, can be represented by a honeycomb-like hexagon. In practice, however, each cell may have an irregular shape depending on different factors including the terrain surrounding the cell. Also, each cell can be further divided into two or more sectors. Each cell is usually divided into 3 sectors, each sector has an angular span of 120 degrees. [0003] A conventional cellular system includes a plurality of geographically distributed cell sites or base stations to support the transmission and reception of communication signals to and from wire...
