1. An apparatus for wireless communications, comprising:
- a plurality of transmitter-receiver pairs; and
a shared non-linear interference cancellation (NLIC) module configurable, in different operating modes of the apparatus involving different transmitter-receiver pairs, to cancel self-jamming interference caused by signals transmitted by one or more transmitters associated with a first set of the plurality of transmitter-receiver pairs on one or more aggressor frequency bands interfering with signals received by one or more receivers associated with a second set of the plurality of transmitter-receiver pairs on one or more victim frequency bands.

Abstract
Certain aspects of the present methods and apparatus provide a scheme to implement a generic Non-Linear Interference Cancelation (NLIC) module that can be interfaced with any topology of aggressor-victim transmitters and/or receivers of any (e.g., one or more) radio-access technology residing on the same communication device.

11. A method for wireless communications, comprising:
-
configuring a shared non-linear interference cancellation (NLIC) module, in a first operating mode involving a first transmitter-receiver pair of a plurality of transmitter-receiver pairings, to cancel self-jamming interference caused by signals transmitted by a first transmitter on a first aggressor frequency band interfering with signals received by a first receiver on a first victim frequency band; and configuring the shared NLIC module, in a second operating mode involving a second transmitter-receiver pair, to cancel self-jamming interference caused by signals transmitted by a second transmitter on a second aggressor frequency band interfering with signals received by a second receiver on a second victim frequency band. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
