Abstract
There is provided mechanisms for polarized reception of reference signals. A method is performed by a terminal device. The terminal device is equipped with an antenna array having dual-polarized antenna elements. The antenna array is connected to a baseband chain in the terminal device. The method comprises receiving, during a beam management procedure with a TRP, two reference signals transmitted in one OFDM symbol each from the same TRP port within a slot. The two reference signals are received using a filter with a first polarization for a first of the two reference signals and with a second polarization for a second of the two reference signals. The second polarization is orthogonal to the first polarization.

A method for polarized reception of reference signals, the method being performed by a terminal device, the terminal device being equipped with an antenna array having dual-polarized antenna elements, the antenna array being connected to a baseband chain in the terminal device, the method comprising:
- receiving, during a beam management procedure with a transmission and reception point (TRP), two reference signals transmitted in one OFDM symbol each from the same TRP port within a slot, the two reference signals belonging to a synchronization signal block (SSB) consisting of four OFDM symbols, the SSB being transmitted over one polarization, wherein the two reference signals are received using a filter with a first polarization for a first of the two reference signals and with a second polarization for a second of the two reference signals, and wherein the second polarization is orthogonal to the first polarization.
A terminal device for polarized reception of reference signals, the terminal device being equipped with comprising:
- a baseband chain;
- an antenna array having dual-polarized antenna elements, the antenna array being connected to the baseband chain;
- and
- processing circuitry, the processing circuitry being configured to cause the terminal device to:
- receive, during a beam management procedure with a transmission and reception point (TRP), two reference signals transmitted in one OFDM symbol each from the same TRP port within a slot, the two reference signals belonging to a synchronization signal block (SSB) consisting of four OFDM symbols, the SSB being transmitted over one polarization, wherein the two reference signals are received using a filter with a first polarization for a first of the two reference signals and with a second polarization for a second of the two reference signals, and wherein the second polarization is orthogonal to the first polarization.
A non-transitory computer readable medium storing a computer program for polarized reception of reference signals, the computer program comprising computer code which, when run on processing circuitry of a terminal device equipped with an antenna array having dual-polarized antenna elements, the antenna array being connected to a baseband chain in the terminal device, causes the terminal device to:
- receive, during a beam management procedure with a transmission and reception point (TRP), two reference signals transmitted in one OFDM symbol each from the same TRP port within a slot, the two reference signals belonging to a synchronization signal block (SSB) consisting of four OFDM symbols, the SSB being transmitted over one polarization, wherein the two reference signals are received using a filter with a first polarization for a first of the two reference signals and with a second polarization for a second of the two reference signals, and wherein the second polarization is orthogonal to the first polarization.
