Abstract

Apparatus and method for communication are provided. The solution comprises controlling a transmitter to map common and dedicated control channels on two frequency blocks and controlling the transmitter to transmit the frequency blocks utilising pair-wise frequency hopping on a shared spectrum.

Claims

1. An apparatus in a communication system, comprising:

at least one processor; and

at least one memory including computer program code,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform;

control a transmitter to map common and dedicated control channels on two frequency blocks; and

control the transmitter to transmit the frequency blocks utilising pairwise frequency hopping on a shared spectrum.

2. The apparatus of claim 1, the apparatus being configured to control the transmitter to transmit on shared data channels using Listen-Before-Talk.

3. The apparatus of claim 1, the apparatus being configured to control the transmitter to utilise more than one non-overlapping frequency resources when transmitting the two frequency blocks utilising pairwise frequency hopping.

4. The apparatus of claim 1, the apparatus being configured to map synchronisation signals to the two frequency blocks.

5. The apparatus of claim 1, the apparatus being configured to control the transmitter to utilise more than one non-overlapping frequency resources when transmitting the two frequency blocks utilising pair-wise frequency hopping, map synchronisation signals to the two frequency blocks and control the transmitter to transmit the synchronisation signals in the largest frequency resource.

6. The apparatus of claim 1, the apparatus being configured to identify wireless local area network channels of a given frequency band and control the transmitter to utilise frequency bands located between the identified wireless local area network channels in the transmission of the two frequency blocks.

7. The apparatus of claim 6, the apparatus being configured to control the transmitter to transmit shared data channels using Listen-Before-Talk on identified wireless local area network channels.

8. An apparatus in a communication system, comprising:

at least one processor; and

at least one memory including computer program code,

the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform;

control a receiver to receive common and dedicated control channels mapped to two frequency blocks utilising pair-wise frequency hopping on a shared spectrum.

9. The apparatus of claim 8, the apparatus being configured to control the receiver to utilise more than one non-overlapping frequency bands in when receiving the two frequency blocks utilising pair-wise frequency hopping.

10. A method in a communication system, comprising:

controlling a transmitter to map common and dedicated control channels on two frequency blocks; and
