Samsung patents method to manage multiple signal formats in 5G networks
This patent describes a way for mobile devices to handle different types of signal structures, known as numerologies, within the same communication window. The device identifies which group of time slots it is in and adjusts its signal processing based on specific timing and frequency settings provided by the network.
In the filing’s own words
Methods and apparatuses for multiple numerologies in wireless communication systems are provided. The methods of UE comprise: identifying first information associated with a set of SF groups including a first SF group and a second SF group, wherein the set of SF groups comprise a number of slots; determining, based on the first information, whether a SF belongs to the first SF group or the second SF group; receiving second information related to a numerology and slot length associated with the set of SF groups; and receiving or transmitting a signal in the SF based on the numerology and slot length included in the second information.
What exactly they claim (claim 1)
1. A user equipment (UE) comprising: a processor configured to: identify first information associated with a set of subframe (SF) groups including a first SF group and a second SF group, wherein the set of SF groups comprise a number of slots, determine, based on the first information, whether a SF belongs to the first SF group or the second SF group, identify a slot length for the first SF group and a subcarrier spacing (SCS) commonly applicable to the first and the second SF groups, and determine a number of orthogonal frequency division multiplexing (OFDM) symbols per slot for the first SF group based on the slot length and the SCS; and a transceiver operably coupled to the processor, the transceiver configured to: receive second information related to a numerology and slot length associated with the set of SF groups, receive a broadcast signaling indicating a value that is used to determine a slot length for the second SF group, wherein a number of OFDM symbols per slot for the second SF group is determined as a function of the indicated value, and receive or transmit a signal in the SF based on the numerology and slot length included in the second information.
