摘要： The present invention discloses a method of requesting resource from a resource allocating apparatus by a request requesting apparatus, a resource allocating apparatus, a resource requesting apparatus and a communication system. The method comprises the following steps: sending a resource request message from the resource requesting apparatus to the resource allocating apparatus; after receiving the resource request message, if resource cannot be allocated within a set time interval with respect to the resource requesting apparatus, sending an acknowledgement for the resource request message from the resource allocating apparatus to the resource requesting apparatus; and if the resource is allocated to the resource requesting apparatus within the set time interval, not sending the acknowledgement for the resource request message from the resource allocating apparatus to the resource requesting apparatus. Utilizing the method and structure of the present invention, the resource allocating apparatus sends additional acknowledgement message only if needed, therefore overhead is reduced much more. Moreover, since the solution of the present invention does not change any signaling exchanged between the resource allocating apparatus and the resource requesting apparatus, it is able to meet the requirement of backward compatibility.

摘要： A method and apparatus for processing protocol data units in network devices of wireless networks are provided. In this solution, data corresponding to different logical connections could be carried in the same protocol data unit. As a result, the overheads of processing information in a system that is irrelevant to data are reduced, especially the overheads for MAC Headers and Sub-headers.
