Method and apparatus that facilitates interference reduction in wireless systems

Abstract

Techniques for managing interference in a wireless communication system are disclosed. In one aspect, one or more frequencies are identified, where transmission by a user equipment (UE) on the one or more frequencies would interfere with reception at the UE. An indication is transmitted to a base station which comprises frequency location information based on the one or more frequencies. Additionally, the UE can receive an assignment of frequency resources from the based station based on the indication.

We claim: 
     
         1 . A method of wireless communication, comprising:
 identifying one or more frequencies on which transmission by a user equipment (UE) causes interference with reception at the UE; and   transmitting an indication to a base station, the indication comprising frequency location information based on the one or more frequencies.   
     
     
         2 . The method of  claim 1 , further comprising:
 receiving an assignment of frequency resources from the base station based on the indication.   
     
     
         3 . The method of  claim 1 , wherein the interference comprises an intermodulation product of the one or more frequencies. 
     
     
         4 . The method of  claim 3 , further comprising:
 determining whether the intermodulation product has a frequency location within a frequency range of the UE reception.   
     
     
         5 . The method of  claim 4 , further comprising:
 identifying multiple distinct frequency intervals that collectively contain the one or more frequencies; and   calculating a frequency interval corresponding to the intermodulation product based on the multiple distinct frequency intervals.   
     
     
         6 . A user equipment (UE), comprising:
 a transmitter configured to transmit wireless signals;   a receiver configured to receive wireless signals; and   a processor configured to:   identify one or more frequencies on which transmission by the transmitter causes interference with reception at the receiver; and   transmit, via the transmitter, an indication to a base station, the indication comprising frequency location information based on the one or more frequencies.   
     
     
         7 . The UE of  claim 6 , wherein the processor is further configured to:
 receive, via the receiver, an assignment of frequency resources from the base station based on the indication.   
     
     
         8 . The UE of  claim 6 , wherein the interference comprises an intermodulation product of the one or more frequencies. 
     
     
         9 . The UE of  claim 8 , wherein the processor is further configured to:
 determine whether the intermodulation product has a frequency location within a frequency range of the reception at the receiver.   
     
     
         10 . The UE of  claim 9 , wherein the processor is further configured to:
 identify multiple distinct frequency intervals that collectively contain the one or more frequencies; and   calculate a frequency interval corresponding to the intermodulation product based on the multiple distinct frequency intervals.   
     
     
         11 . An apparatus of wireless communications, comprising:
 means for identifying one or more frequencies on which transmission by a user equipment (UE) causes interference with reception at the UE; and   means for transmitting an indication to a base station, the indication comprising frequency location information based on the one or more frequencies.   
     
     
         12 . The apparatus of  claim 11 , further comprising:
 means for receiving an assignment of frequency resources from the base station based on the indication.   
     
     
         13 . The apparatus of  claim 11 , wherein the interference comprises an intermodulation product of the one or more frequencies. 
     
     
         14 . The apparatus of  claim 13 , further comprising:
 means for determining whether the intermodulation product has a frequency location within a frequency range of the UE reception.   
     
     
         15 . A non-transitory computer-readable medium having instructions stored thereon, the instructions comprising codes executable to cause a user equipment (UE) to:
 identify one or more frequencies on which transmission by the UE causes interference with reception at the UE; and   transmit an indication to a base station, the indication comprising frequency location information based on the one or more frequencies.   
     
     
         16 . The medium of  claim 15 , further comprising codes to:
 receive an assignment of frequency resources from the base station based on the indication.   
     
     
         17 . The medium of  claim 15 , wherein the interference comprises an intermodulation product of the one or more frequencies. 
     
     
         18 . The medium of  claim 17 , further comprising codes to:
 determine whether the intermodulation product has a frequency location within a frequency range of the UE reception.
