A dynamic distribution of traffic load across multiple carriers in a wireless communication system. The wireless communication system includes a Base Transmittal Station (BTS) and one or more Access Terminals (ATs). An arriving traffic flow is placed on the carrier pair preferably having the most excess capacity. It is determined whether the new traffic flow is symmetric or asymmetric, and whether it is a best effort (BE) or a delay sensitive (DS) flow type. A procedure is then selected and used to calculate a loading metric for each carrier pair, the new traffic flow being assigned to the carrier pair having the lowest metric.

Method of multi-carrier traffic allocation for wireless communication system

A base station, mobile station, and/or other terminal includes physical layer (layer ) protocol and link layer (layer ) protocol enhancements that interact with one another to cause the link layer protocol to inhibit is ARQ operations for data blocks having missing data packets that are still pending at the physical layer. A mobile station (or base station) receives a data packet from a base station across a wireless link. The physical layer then determines, a number, N, of data packets pending with its physical layer Automatic Retransmission reQuest (ARQ) operations. The physical layer then passes the data packet and the number, N, to a link layer operating on the mobile station. The link layer then modifies its ARQ operations based upon the number, N, of data packets pending with the physical layer ARQ operations. The link layer inhibits ARQ operations for data blocks missing data packets that are still pending with the physical layer.
