Sony patents method to adjust signal quality checks in mixed wireless networks
Sony describes a way for devices to measure signal strength from cell towers when the network uses a mix of standard and simultaneous transmission/reception modes. The device adjusts its quality readings based on which type of data slot the signal arrives in to ensure accurate measurements.
In the filing’s own words
A method of operating a communications device configured to communicate with infrastructure equipment of a wireless communications network via a wireless access interface. The method includes receiving, through the wireless access interface, one or more synchronisation signal block (SSB) burst sets, each burst set comprising one or more SSBs received on one or more respective beams. The wireless access interface comprises a plurality of slots including a plurality of orthogonal frequency division multiplexing (OFDM) symbols for carrying the SSBs in the burst set, wherein one or more of the OFDM symbols are SBFD OFDM symbols and one or more are non-SBFD OFDM symbols. The method further comprises determining a signal quality for each beam based on a measurement of one or more SSBs received on the beam, including adjusting the signal quality measurement according to whether the SSBs are received in the SBFD OFDM symbols or the non-SBFD OFDM symbols.
What exactly they claim (claim 1)
1. A method of operating a communications device, the method comprising receiving, from infrastructure equipment of a wireless communications network via a wireless access interface, one or more synchronisation signal block, SSB, burst sets, each burst set comprising one or more SSBs, the one or more SSBs in each burst set being received on a respective one or more beams, wherein the wireless access interface comprises a plurality of slots, each of the plurality of slots comprising a plurality of Orthogonal Frequency Division Multiplexing, OFDM, symbols for receiving the one or more of SSBs in each burst set, one or more of the OFDM symbols being SBFD OFDM symbols and one or more of the OFDM symbols being non-SBFD OFDM symbols, determining a signal quality for each beam based on a signal quality measurement of one or more of the SSBs received on the beam including adjusting the measurement of the signal quality of the one or more of SSBs received on the beam according to whether they are received in the plurality of SBFD OFDM symbols or the plurality of non-SBFD OFDM symbols.
