Samsung patents method for organizing wireless signal paths in 5G networks

Patent drawing
Patent drawing from the official filing.

This filing describes a way for phones to sort wireless signal settings into two separate groups. The phone checks which group a specific signal belongs to before trying to read instructions from the network.

Why it mattersIt helps phones manage complex 5G connections more efficiently by organizing how they interpret signal directions.

In the filing’s own words

Methods and apparatuses for transmission configuration indication (TCI) state indication and association for control and data channels. A method performed by a user equipment (UE) includes receiving first information for first and second groups of configured TCI states; receiving, in a downlink control information (DCI), a first indicated TCI state of a TCI codepoint; and receiving second information for a first control resource set (CORESET). The method further includes identifying, based on the first information, whether the first indicated TCI state is associated with the first or second group of configured TCI states; identifying, based on the second information, whether the first CORESET is associated with the first or second group of configured TCI states; and based on identifying that the first indicated TCI state and the first CORESET are associated with the same group of configured TCI states, receiving physical downlink control channel (PDCCH) candidates in the first CORESET according to the first indicated TCI state.

What exactly they claim (claim 1)

1. A user equipment (UE), comprising: a transceiver configured to receive, from a base station (BS), a first radio resource control (RRC) message including a first indicator for applying at least one indicated transmission configuration indication (TCI) state for a reception of a physical downlink control channel (PDCCH) in a first control resource set (CORESET); and a processor operably coupled with the transceiver, the processor configured to identify at least one TCI state for the reception of the PDCCH based on the first indicator among two indicated TCI states, wherein the transceiver is further configured to receive, from the BS, the PDCCH based on assuming that a demodulation reference signal (DM-RS) antenna port is quasi co-located with a reference signal provided by the at least one indicated TCI state.
