Samsung patents method for managing signal beams in full-duplex networks

This patent describes a way for a phone to know which signal beam to use when it is sending and receiving data at the same time. It works by splitting time slots into two groups: one for normal communication and one for full-duplex activity, each using a specific beam setting.

Why it mattersThis improves how devices handle data traffic in future 5G or 6G networks by reducing confusion when a device talks and listens simultaneously.

In the filing’s own words

Methods and apparatuses for beam indication for full duplex. A method of operating a user equipment (UE) includes receiving first and second information that includes first and second transmission configuration indicator (TCI) state configurations associated with first and second subsets of slots or symbols, respectively, on a cell and receiving a downlink control information (DCI) format that includes a first or second TCI state code point from the first or second TCI state configuration. The method further includes determining, based on whether a slot or symbol is from the first or second subset, the first or second TCI state code point and receiving, based on the determination, a shared data or control channel or signal using the first or second TCI state code point. The first subset does not include time-domain resources indicated for simultaneous transmission and reception on the cell and the second subset does.

What exactly they claim (claim 1)

1. A user equipment (UE) comprising: a transceiver configured to receive: first information that includes a first transmission configuration indicator (TCI) state configuration associated with a first subset of slots or symbols from a set of slots or symbols on a cell, second information that includes a second TCI state configuration associated with a second subset of slots or symbols from the set of slots or symbols on the cell, and a downlink control information (DCI) format that includes a first TCI state code point from the first TCI state configuration or a second TCI state code point from the second TCI state configuration; and a processor operably coupled to the transceiver, the processor configured to determine, based on whether a slot or symbol is from the first subset of slots or symbols or the second subset of slots or symbols, the first TCI state code point or the second TCI state code point, wherein the transceiver is further configured to: receive, based on the determination that the slot or symbol is from the first subset of slots or symbols, a shared data or control channel or signal using the first TCI state code point, and receive, based on the determination that the slot or symbol is from the second subset of slots or symbols, the shared data or control channel or signal using the second TCI state code point, wherein the first subset of slots or symbols does not include time-domain resources indicated for simultaneous transmission and reception on the cell, and wherein the second subset of slots or symbols includes time-domain resources indicated for simultaneous transmission and reception on the cell.
