In an embodiment, a method is provided that includes receiving a descrambled resource element associated with selected second channel state information (CSI2) and receiving a descrambling sequence used to generate the descrambled RE. The method also includes rescrambling the descrambled RE using the descrambling sequence to generate a rescrambled RE and modifying the descrambling sequence to generate a modified descrambling sequence. The method also includes descrambling the rescrambled RE with the modified descrambling sequence to generate a modified descrambled RE and accumulating the modified descrambled RE to form a combined CSI2 value. ## Claims ### Claim 1 A method for processing wireless data via a communication network, comprising: receiving one or more symbols via uplink transmissions from a user equipment through a 5G communication network;
