Abstract
A method of wireless communication includes receiving a first interference signal and a second interference signal. The method further includes determining whether the second interference signal includes a different version of the first interference signal. Additionally, the method includes combining the first interference signal and the second interference signal to estimate an interference cancellation signal when the second interference signal is the different version of the first interference signal.
Claims26
A method of wireless communication by a wireless device in a wireless communication system, comprising:
- receiving a first interference signal at a receiver;
- receiving a second interference signal at the receiver;
- determining whether the second interference signal and the first interference signal are different versions of a same interference signal;
- and
- combining the first interference signal and the second interference signal to estimate an interference cancellation signal when the second interference signal and the first interference signal are different versions of the same interference signal.
An apparatus for wireless communications, comprising:
- a memory;
- and
- at least one processor coupled to the memory, the at least one processor being configured:
- to receive a first interference signal at a receiver;
- to receive a second interference signal at the receiver;
- to determine whether the second interference signal and the first interference signal are different versions of a same interference signal;
- and
- to combine the first interference signal and the second interference signal to estimate an interference cancellation signal when the second interference signal and the first interference signal are different versions of the same interference signal.
An apparatus for wireless communications, comprising:
- means for receiving a first interference signal at a receiver;
- means for receiving a second interference signal at the receiver;
- means for determining whether the second interference signal and the first interference signal are different versions of a same interference signal;
- and
- means for combining the first interference signal and the second interference signal to estimate an interference cancellation signal when the second interference signal and the first interference signal are different versions of the same interference signal.
A computer program product for wireless communications, the computer program product comprising:
- a non-transitory computer-readable medium having program code recorded thereon, the program code comprising:
- program code to receive a first interference signal at a receiver;
- program code to receive a second interference signal at the receiver;
- program code to determine whether the second interference signal and the first interference signal are different versions of a same interference signal;
- and
- program code to combine the first interference signal and the second interference signal to estimate an interference cancellation signal when the second interference signal and the first interference signal are different versions of the same interference signal.
