Abstract
Herein a Radio Access node for multi band communication and a method therein are described. The Radio Access node is configured for communication with at least one wireless device in a first frequency band. The method comprises performing at least one measurement in a second frequency band, by use of a feedback receiver. The at least one measurement is performed in order to detect signals, in the second frequency band, produced by other entities than the Radio Access node. The feedback receiver is also operable to measure signals transmitted by the Radio Access node.

A method for multi band communication, performed by a Radio Access (RA) node of a wireless communication network, the RA node being operable to communicate with at least one wireless device (WD) in a first frequency band, the method comprising:
- performing at least one measurement in a second frequency band, by use of a feedback receiver, in order to detect signals produced by other entities than the RA node;
- wherein the feedback receiver also is operable to measure signals transmitted by the RA node;
- and
- selecting, based on the performed at least one measurement, an operational frequency within the second frequency band for communication with the at least one WD.
A Radio Access (RA) node for multi-band communication and operable in a wireless communication network, the RA node configured for being operable to communicate with at least one wireless device (WD) in a first frequency band;
- the RA node comprising:
- processing circuitry;
- memory containing instructions executable by the processing circuitry whereby the RA node is operative to:
- perform at least one measurement in a second frequency band by use of a feedback receiver, in order to detect signals produced by other entities than the RA node;
- wherein the feedback receiver also is operable to measure signals transmitted by the RA node;
- and
- select, based on the performed at least one measurement, an operational frequency in the second frequency band for communication with the at least one WD.
The RA node of claim 13, wherein the instructions are such that the RA node is operable to convert, when the feedback receiver is associated with the transmitter operable in the first frequency band, a detected signal in the second frequency band to the first frequency band.
