Method for negotiating the maximum resource for sharing in OFDMA-based communications system

摘要

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.

1. A method for resource allocation in a wireless communications network comprising an access network and an access terminal, the method comprising:
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, and wherein the step of setting the maximum usable channel size comprises:
receiving a report of a maximum decoding bandwidth of the access terminal by the access network;selecting the maximum usable channel size, wherein the maximum usable channel size is not greater than the maximum decoding bandwidth; andsending a message from the access network to the access terminal to set the maximum usable channel size, wherein the maximum usable channel size is specified using a table known by the access network and the access terminal, and wherein the table comprises one-to-one mapping between the maximum usable channel size and a field in the message.
