Embodiment Construction

[0017] The details shown here are by way of example and for purposes of illustrative discussion of preferred embodiments of the invention. The description in conjunction with the accompanying drawings enables those skilled in the art to understand how other different embodiments of the present invention can be realized in practice.

[0018] In addition, in order to avoid unclearness of the present invention, it is also considered that the details of implementing the block diagram structure largely depend on the network environment in which the embodiment of the present invention will be implemented, that is, the details should be expressed in the form of a block diagram within the understanding scope of those skilled in the art individual units. Although in figure 1 The preferred embodiment of the present invention is described in reference to the example system block diagram of 3GPP Release 99, but embodiments of the present invention may be implemented in other wireless co...

Abstract

A wireless communications network has a plurality of terminals and at least one base station which transmits data to each one of said plurality of terminals on a wireless downlink and receives data from each one of said plurality of terminals on a wireless uplink. One of the terminals sends a rate request to the base station. The rate request requests that the data rate on the wireless uplink for the terminal be changed. In response to the rate request, the base station sends a rate grant to the terminal. The rate grant indicates whether or not the terminal may change the data rate on the wireless uplink.

Description

technical field [0001] The present invention relates generally to the field of wireless communications. In particular, the invention relates to uplink enhancement in the air interface between a terminal and a base station of a wireless communication network. Background technique [0002] The air interface between terminals and base stations in a wireless communication network is directly related to the level of performance achievable by the network. Since the physical layer defines the basic capability limit of the air interface, it is necessary to have a low Signal-to-Interference Ratio (SIR) requirement for adequate link performance with different coding and diversity schemes in the physical layer. [0003] In third-generation wireless communication systems, such as the Joint Standardization Project of the Third Generation Partnership Project ( www.3gpp.org ) In the wireless communication network specified in version 99 or later, the physical layer is not designed around...
