Embodiment Construction

[0023] The invention provides a unique method and device for realizing soft handover in an OFDMA-based communication system. The following disclosure presents many different embodiments or examples of implementing different features of the invention. Specific examples of components, circuits, signals, messages, protocols, and arrangements are used in the following description to simplify the illustration. But these are only examples and cannot be used to limit the scope of protection of the claims of the present invention. For clear understanding of the present invention, the known parts will not be described in detail. For the most part, details not necessary to a complete understanding of the invention have been left out, since such details are within the skill of those skilled in the art.

[0024] In soft handover, the mobile station receives data from more than one sector at the same time. Multiple sectors send the same data. Sectors that transmit the same data are ref...

Abstract

A method of enabling a soft handoff in a communication system, wherein the communication system includes a plurality of sectors and each of the plurality of sectors includes at least one base station is disclosed. The method includes: providing at least one mobile station; setting identical resources for serving the mobile station from each of the plurality of base stations in each sector; designating at least a plurality of base stations in at least one sector to participate a soft handoff; and performing a soft handoff.

Description

technical field [0001] The present invention relates to a wireless communication system, in particular to a new method and device for realizing soft handover in the wireless communication system. Background technique [0002] In a cellular communication network based on Orthogonal Frequency Division Multiplexing (OFDM), a base station communicates with mobile stations within its coverage area using signals that are orthogonal in frequency. Furthermore, current third generation (3G) systems utilize multi-user diversity gains to significantly increase their throughput compared to second generation (2G) systems. That is to say, for point-to-multipoint systems, such as forward link systems (forward link systems), all resources of the base station are dedicated to a single user (also known as a mobile station). [0003] Scheduler The scheduler in the base station selects a user with the best radio reception from a group of users when necessary. If the group of users is large en...
