Samsung patents method to streamline 5G signal checks across multiple carriers

Patent drawing
Patent drawing from the official filing.

This filing describes a way for 5G phones to more efficiently search for control signals when using multiple data carriers at once. It involves checking specific resource locations on a secondary carrier to find instructions meant for the primary connection, reducing unnecessary scanning.

Why it mattersIt helps mobile devices manage complex 5G connections with less effort, potentially improving battery life or responsiveness in crowded networks.

In the filing’s own words

The present disclosure relates to a communication method and system for converging a 5th-generation (5G) communication system for supporting higher data rates beyond a 4th-generation (4G) system with a technology for internet of things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Embodiments of the present disclosure provide a blind detection method for Physical Downlink Control Channel (PDCCH) candidate, comprising: determining a resource location of a serving cell for transmitting the PDCCH candidate corresponding to a Primary cell (Pcell), wherein, the serving cell includes Pcell and/or Secondary cell (Scell); and blindly detecting the PDCCH candidate corresponding to Pcell on the determined resource location of the serving cell. Based on the solution of the embodiment of the present application, in a CA system, the allocation of the resources occupied by the PDCCH can be implemented more reasonably and effectively.

What exactly they claim (claim 1)

1. A method performed by a user equipment (UE) in a communication system, the method comprising: receiving, from a base station, configuration information for a first carrier and a second carrier, wherein the first carrier and the second carrier are associated with physical downlink control channel (PDCCH) candidates corresponding to the first carrier, identifying a first number of PDCCH candidates to be monitored on the first carrier and a second number of PDCCH candidates to be monitored on a second carrier; monitoring a first set of PDCCH candidates corresponding to the first carrier on the first carrier based on the first number of PDCCH candidates; and monitoring a second set of PDCCH candidates corresponding to the first carrier on the second carrier based on the second number of PDCCH candidates.
