First Claim
Patent Images
1. A method of a User Equipment (UE) for interference control in a wireless communication system, the method comprising:
- receiving a signal of a DownLink (DL) frequency band that is adjacent to an UpLink (UL) frequency band supported by the UE;
measuring a Received Signal Strength Indicator (RSSI) of the DL frequency band signal;
comparing the measured RSSI with a threshold value; and
if the measured RSSI is less than the threshold value, limiting UL transmission.

Abstract
An apparatus and a method for controlling interference in a wireless communication system are provided. The method includes receiving a signal of a DownLink (DL) frequency band that is adjacent to an UpLink (UL) frequency band supported by a User Equipment (UE), measuring a Received Signal Strength Indicator (RSSI) of the DL frequency band signal, comparing the measured RSSI with a threshold value, and, if the measured RSSI is less than the threshold value, limiting UL transmission.

4. The method of claim 4, wherein, if the RSSI is less than the threshold value, at least one receive signal is less than the threshold value among a plurality of the RSSIs measured by carrier.
-
6. The method of claim 6, wherein the limiting of the UL resource allocation position comprises:
-
transmitting to the AP a buffer status report message comprising an amount less than an amount of information intended for transmission; and receiving an allocation of a UL resource dependent on a buffer status from the AP.

10. An apparatus of a User Equipment (UE) for interference control in a wireless communication system, the apparatus comprising:
-
a receiving path for receiving a signal of a DownLink (DL) frequency band that is adjacent to an UpLink (UL) frequency band supported by the UE; and a Radio Frequency (RF) Integrated Circuit (IC) for comparing a Received Signal Strength Indicator (RSSI) of the DL frequency band signal with a threshold value, and for limiting UL transmission based on comparison result.
-
- 11. The apparatus of claim 11, wherein the RF IC measures an RSSI of the DL frequency band signal at least one of every predefined period to the UE and every predefined gap duration scheduled in an Access Point (AP).
