Benefits of technology

This approach enhances the utilization of group resources by allowing secondary terminals to access leftover resources effectively, thereby improving the overall efficiency of resource allocation and usage within the network.

Problems solved by technology

Voice traffic, while being a part of a real-time application, is usually discontinuous in nature and comprises large inactive periods.
In conventional OFDMA networks, at any time, most likely, only some of the ATs are active, and hence the group resources assigned to the respective group may not be fully used.
Particularly, in a lightly loaded resource group, most of the group resources may be idle.

Embodiment Construction

[0024]The making and using of the presently preferred embodiments are discussed in detail below. It should be appreciated, however, that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.

[0025]FIG. 1 illustrates wireless network 10, which may be an orthogonal frequency division multiple access (OFDMA) network. Wireless network 10 includes various elements, such as an access network (AN), a plurality of ATs (AT) 12 and 14, and the like. The plurality of ATs is wirelessly connected to the AN, which may go through base stations (not shown) as parts of the AN. Preferably, the AN is configured to provide both voice and data communication. The plurality of ATs may include mobile phones for the voice communication, and other types of terminals for the data communica...

Abstract

A method for resource allocation in a wireless communications network and the respective wireless communications system are provided. The method includes providing an access network; providing an access terminal; joining the access terminal into a group of the access network, wherein access terminals in the group share a group of resources; and setting a maximum usable channel size for the access terminal, wherein the maximum usable channel size limits a maximum number of leftover resources used by the access terminal.

Description

[0001]This application is a continuation of U.S. patent application Ser.
