Abstract
There is provided mechanisms for signalling, towards user equipment, a spatial relation between component carriers on which SSBs are to be transmitted. A method is performed by a network node. The method comprises signalling, towards the user equipment is served by the network node, an indication of spatial QCL among the SSBs to be transmitted on different ones of the component carriers. The method comprises initiating transmission of the SSBs on the component carriers.
Claims26
A method for signalling, towards a user equipment, a spatial relation between component carriers on which synchronization signal blocks (SSBs) are to be transmitted, the method being performed by a network node, the method comprising:
- signalling, towards the user equipment being served by the network node, an indication of spatial quasi-colocation (QCL) among the SSBs to be transmitted on different ones of the component carriers;
- and
- initiating transmission of the SSBs on the component carriers, wherein
- each SSB is to be transmitted using a respective spatial filter,
- the indication defines which of the SSBs that on the component carriers are to be transmitted using the same spatial filter, and
- the SSBs are to be transmitted in timeslots, and wherein the SSBs that on the component carriers are to be transmitted using the same spatial filter are to be transmitted in the same timeslot.

A method for receiving an indication of a spatial relation between component carriers on which synchronization signal blocks (SSBs) are to be transmitted, the method being performed by a user equipment, the method comprising:
- receiving signalling, from a network node serving the user equipment, of an indication of spatial quasi-colocation (QCL) among the SSBs to be transmitted on different ones of the component carriers;
- and
- receiving the SSBs on the component carriers, wherein
- each SSB is to be transmitted using a respective spatial filter,
- the indication defines which of the SSBs that on the component carriers are to be transmitted using the same spatial filter, and
- the SSBs are to be transmitted in timeslots, and wherein the SSBs that on the component carriers are to be transmitted using the same spatial filter are to be transmitted in the same timeslot.

A user equipment for receiving an indication of a spatial relation between component carriers on which synchronization signal blocks (SSBs) are to be transmitted, the user equipment comprising processing circuitry, the processing circuitry being configured to cause the user equipment to:
- receive signalling, from a network node serving the user equipment, of an indication of spatial quasi-colocation (QCL) among the SSBs to be transmitted on different ones of the component carriers;
- and
- receive the SSBs on the component carriers.

A non-transitory computer readable storage medium storing a computer program for signalling, towards a user equipment, a spatial relation between component carriers on which synchronization signal blocks (SSBs) are to be transmitted, the computer program comprising computer code which, when run on processing circuitry of a network node, causes the network node to:
- signal, towards the user equipment being served by the network node, an indication of spatial quasi-colocation (QCL) among the SSBs to be transmitted on different ones of the component carriers;
- and
- initiate transmission of the SSBs on the component carriers.
