Abstract
Methods and apparatus for combining received uplink transmissions. 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.
Claims20
A method, comprising:
- receiving descrambled resource elements (REs) comprising selected second channel state information (CSI2);
- receiving descrambling sequences used to generate the descrambled REs;
- rescrambling the descrambled REs using the descrambling sequences to generate rescrambled REs;
- modifying the descrambling sequences to generate modified descrambling sequences;
- descrambling the rescrambled REs with the modified descrambling sequences to generate modified descrambled REs;
- and
- accumulating the modified descrambled REs to form combined CSI2 values.
An apparatus, comprising:
- a processor that receives descrambled resource elements (REs) associated with selected second channel state information (CSI2), and receives descrambling sequences used to generate the descrambled REs;
- and
- a hypothesis processor that rescrambles the descrambled REs using the descrambling sequences to generate rescrambled REs, modifies the descrambling sequences to generate modified descrambling sequences, descrambles the rescrambled REs with the modified descrambling sequences to generate modified descrambled REs, and accumulates the modified descrambled REs to form combined CSI2 values.
An apparatus, comprising:
- means for receiving descrambled resource elements (REs) comprising selected second channel state information (CSI2);
- means for receiving descrambling sequences used to generate the descrambled REs;
- means for rescrambling the descrambled REs using the descrambling sequences to generate rescrambled REs;
- means for modifying the descrambling sequences to generate modified descrambling sequences;
- means for descrambling the rescrambled REs with the modified descrambling sequences to generate modified descrambled REs;
- and
- means for accumulating the modified descrambled REs to form combined CSI2 values.
