Samsung patents method for phones to sync across multiple radio frequencies
Samsung describes a way for a phone to connect to a second radio frequency by using the timing and frequency data from its primary connection. The phone receives a list of available frequencies and uses a calculated offset to align its signal with the new one. This allows the device to send a connection request on the second frequency without needing separate synchronization signals.
In the filing’s own words
Apparatuses and methods for coexistence of radio access technologies on one or more cells. A method for a user equipment (UE) includes receiving a synchronization signal on a first cell or carrier, determining, based on the synchronization signal, a first time and frequency (T/F) reference for receptions on the first cell or carrier, and receiving, on the first cell or carrier, first information that indicates a list of cells or carriers. The method determining a second cell or carrier from the list of cells or carriers and determining a second T/F reference for receptions on the second cell or carrier to be the first T/F reference or a sum of a T/F offset and the first T/F reference. The T/F offset is included in the first information. The method further includes receiving, on the first cell or carrier, second information for a random access (RA) procedure on the second cell or carrier, transmitting, based on the second information, a physical random access channel (PRACH) on the second cell or carrier, and receiving, on the second cell or carrier, a random access response (RAR) associated with the PRACH.
What exactly they claim (claim 1)
1. A method for a user equipment (UE), the method comprising: receiving a synchronization signal on a first cell or carrier; determining, based on the synchronization signal, a first time and frequency (T/F) reference for receptions on the first cell or carrier; receiving, on the first cell or carrier, first information that indicates a list of cells or carriers; determining a second cell or carrier from the list of cells or carriers; determining a second T/F reference for receptions on the second cell or carrier to be: the first T/F reference, or a sum of a T/F offset and the first T/F reference, wherein the T/F offset is included in the first information; receiving, on the first cell or carrier, second information for a random access (RA) procedure on the second cell or carrier; transmitting, based on the second information, a physical random access channel (PRACH) on the second cell or carrier; and receiving, on the second cell or carrier, a random access response (RAR) associated with the PRACH.
