Abstract
A method of a communication device arranged to operate in a cellular communication system is presented. The method comprises receiving a control symbol from a network node operating a cell of the cellular communication system and serving the communication device, determining interference situation for the control symbol, selecting an interference mitigation algorithm based on the determined interference, and performing the selected interference mitigation algorithm for the received control symbol. A communication device arranged to perform interference mitigation for received control symbols by the method, and a computer program for the communication device are also presented.
Claims16
A method performed by a communication device arranged to operate in a cellular communication system, the method comprising
- receiving a control symbol from a network node operating a cell of the cellular communication system and serving the communication device;
- determining an interference situation for the control symbol, including whether the control symbol collides in time and frequency with corresponding control symbols associated with neighbouring interfering cells;
- selecting a first interference mitigation algorithm based on determining that the control symbol collides in time and frequency;
- based on determining that the control symbol does not collide in time and frequency, selecting between the first interference mitigation algorithm and at least one other interference mitigation algorithm;
- and
- performing the selected interference mitigation algorithm for the received control symbol.
A communication device arranged to operate in a cellular communication system comprising a cell operated by a network node serving the communication device, wherein the communication device comprises:
- at least one processor;
- and
- at least one computer-readable medium storing computer-executable instructions that, when executed by the at least one processor, configure the communication device to:
- receive a control symbol from the network node;
- determine an interference situation for the control symbol, including whether the control symbol collides in time and frequency with corresponding control symbols associated with neighbouring interfering cells;
- select a first interference mitigation algorithm based on determining that the control symbol collides in time and frequency;
- based on determining that the control symbol does not collide in time and frequency, select between the first interference mitigation algorithm and at least one other available interference mitigation algorithm;
- and
- perform the selected interference mitigation algorithm for the received control symbol.
