Samsung patents method to measure signal quality in mixed 5G networks

This patent describes a way for mobile devices to report how well they are receiving a signal in networks that use subband full duplex (SBFD) technology. The device checks if a specific time slot is using SBFD or standard transmission, then picks the correct measurement method to send an accurate quality report back to the network.

Why it mattersThis helps network operators manage data flow more efficiently by ensuring they have accurate information about signal strength in complex, mixed-mode 5G environments.

In the filing’s own words

Apparatuses and methods for channel quality reporting for full duplex systems. A method performed by a user equipment (UE) includes receiving information about a channel state information (CSI) report associated with N>1 hypotheses. A first hypothesis of the N hypotheses is associated with a channel quality indicator (CQI) for subband full duplex (SBFD) slots or symbols. A second hypothesis of the N hypotheses is associated with a CQI for non-SBFD slots or symbols. The method further includes identifying whether a slot or symbol is SBFD or non-SBFD; determining, based on the identification, a CQI using the first or second hypotheses; and transmitting the CSI report, including the determined CQI.

What exactly they claim (claim 1)

1. A user equipment (UE) comprising: a transceiver configured to receive information about a channel state information (CSI) report associated with N>1 hypotheses, wherein: a first hypothesis of the N hypotheses is associated with a channel quality indicator (CQI) for a first type of slots or symbols, and a second hypothesis of the N hypotheses is associated with a CQI for a second type of slots or symbols; and a processor operably coupled to the transceiver, the processor configured to: identify whether a slot or symbol is of the first type or the second type; and determine, based on the identification, a CQI using the first or second hypotheses; wherein the transceiver is further configured to transmit the CSI report including the determined CQI, wherein the first type of slots or symbols correspond to subband full duplex (SBFD) slots or symbols, and wherein the second type of slots or symbols correspond to non-SBFD slots or symbols.
