Beam forming for synchronization signals
First Claim
1. A method for a network node configured to transmit wireless communication signals using beam forming and configured to apply any of one or more data carrying beam widths for transmission of data carrying signals dedicated to a specific wireless communication device, the method comprising:
- determining one or more requirement parameters for transmission of synchronization signals, wherein the one or more requirement parameters comprise a desired synchronization signal beam width and a minimum effective power, and wherein the determined desired synchronization signal beam width is larger than a minimum one of the data carrying beam widths;
calculating beam forming weights based on the one or more requirement parameters by assigning non-zero values to a number of beam forming weights that exceeds a minimum number of beam forming weights for the determined desired synchronization signal beam width, wherein a beam resulting from the calculated beam forming weights has a beam width larger than or equal to the determined desired synchronization signal beam width, and an effective power larger than or equal to the minimum effective power;
generating a synchronization signal for transmission; and
transmitting the generated synchronization signal using the calculated beam forming weights.

Abstract
A method is disclosed for a network node configured to transmit wireless communication signals using beam forming and configured to apply any of one or more data carrying beam widths for transmission of data carrying signals dedicated to a specific wireless communication device.
The method comprises determining one or more requirement parameters for transmission of synchronization signals, wherein the one or more requirement parameters comprise a desired synchronization signal beam width and a minimum effective power, and wherein the determined desired synchronization signal beam width is larger than a minimum one of the data carrying beam widths.
The method also comprises calculating beam forming weights based on the one or more requirement parameters, wherein a beam resulting from the calculated beam forming weights has a beam width larger than, or equal to, the determined desired synchronization signal beam width and an effective power larger than, or equal to, the minimum effective power, and wherein the calculation is performed by assigning non-zero value to a number of beam forming weights which exceeds a minimum number of beam forming weights for the determined desired synchronization signal beam width.
The method further comprises generating a synchronization signal for transmission and transmitting the generated synchronization signal using the calculated beam forming weights.
Corresponding arrangement, network node and computer program product are also disclosed.
