Embodiment Construction

[0031]The embodiment of the present invention provides a resource management method for MC-CDMA system. When describing the embodiments of the present invention, the same terms as those used in the 1x-EVDO system proposed in 3GPP2C.S0024-A v2.0 will be used. Moreover, it will also be understood that these terms have the same definitions as set forth in 3GPP2C.S0024-Av2.0 and are determined in the same manner as set forth in 3GPP2C.S0024-Av2.0 unless expressly stated to the contrary . For simplicity, embodiments of the invention will be described with respect to reverse link resource management. Also, for simplicity, embodiments of the invention will address any number of radio links or application streams (e.g., one or more applications running at the AT) and MC-CDMA systems employing N carriers (where N is greater than 1) situation to describe.

Abstract

In one embodiment, a transmission resource for transmitting data from a number of applications in a multiple carrier communication system is managed. In this embodiment, an aggregate transmission resource available to the number of applications is determined, and the determined aggregated transmission resource is distributed to each carrier based on a load on each carrier. In another embodiment apotential transmission resource for each application on each carrier is determined, and a carrier transmission resource for each carrier is determined based on the determined potential transmission resource for each application on the carrier. Data from at least one of the applications is assigned to at least one of the carriers based on the transmission resource distributed to or determined for the carrier, and the assigned data is transmitted on the carrier.

Description

[0001] Domestic Priority Information [0002] This application is a continuation-in-part of Application Serial No. 11 / 334,421 filed January 19, 2006, the entire contents of which are hereby incorporated by reference. Background technique [0003] Code Division Multiple Access (CDMA) communication systems are designed to operate over a fixed size bandwidth. For example, a 1x-EVDO communication system operates on a 1.25MHz bandwidth. Because of this limited resource, resource management plays an important role in CDMA communication systems. In a 1x-EVDO communication system, a Base Transceiver (BTS) serves the communication needs of Access Terminals (ATs) in the BTS coverage area. An AT can be a wireless phone, a wireless-equipped PDA or a computer, etc.; it can also be called a mobile station or a mobile unit. Communication from the BTS to the AT is called forward or downlink communication, and communication from the AT to the BTS is called reverse or uplink communication. ...
