Abstract: Disclosed is a method and system for validating a data packet by a network processor supporting a first network protocol and a second network protocol and utilizing shared hardware. The network processor receives a data packet; identifies a network packet protocol for the data packet; and processes the data packet according to the network packet protocol comprising: updating a first register with a first partial packet length specific to the first network protocol; updating a second register with a second partial packet length specific to the second network protocol; and updating a third register with a first checksum computed from fields independent of the network protocol. The system produces a second checksum utilizing a function that combines values from the first register, the second register, and the third register. The system validates the data packet by comparing the data packet checksum to the second checksum.

Abstract: A method for wirelessly transmitting data and control information using a plurality of transmission layers includes determining a number of bits in one or more user data codewords to be transmitted during a subframe and calculating, for each of M control signals to be transmitted during the subframe, a value (Q′), based at least in part, on the number of bits in the one or more user data codewords, and an estimated number of user data vector symbols onto which the one or more user data codewords will be mapped. The estimate of the number of user data vector symbols for a particular one of the M control signals depends, at least in part, on a number of control vector symbols to be allocated to one or more others of the M control signals. The method also includes determining a number of control vector symbols onto which to map each of the M control signals based on a respective value Q′ calculated for that control signal, mapping the control signals for that control signal, and transmitting the control vector symbols.
