Samsung patents method to send one signal controlling multiple 5G data streams
This patent describes a way for a phone to receive a single control message that tells it where to find data across several different network channels at once. Instead of needing a separate instruction for each channel, the device uses one signal to manage multiple data streams, which reduces the amount of network space used for sending commands.
In the filing’s own words
According to an embodiment of the present disclosure, a method and an apparatus for receiving downlink control information (DCI) by a user equipment (UE) in a wireless communication system is provided, the method comprises receiving downlink control information (DCI) on one serving cell, identifying whether or not the DCI schedules physical downlink shared channels (PDSCHs) of a plurality of serving cells, receiving data on a PDSCH of the one serving cell in case that the DCI schedules the PDSCH of the one serving cell, and receiving data on the PDSCHs of the plurality of serving cells in case that the DCI schedules the PDSCHs of the plurality of serving cells. Based on the solution provided in the embodiments of the present disclosure, the aspect of being able to schedule the PDSCH of one or more serving cells on one physical downlink control channel (PDCCH) can be achieved and resources occupied by the PDCCH can be saved.
What exactly they claim (claim 1)
1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising: receiving, from a base station, information on a downlink control information (DCI) format for scheduling one physical downlink shared channel (PDSCH) in one cell or multiple PDSCHs in multiple cells; receiving data on the one PDSCH of the one cell in case that the DCI format schedules the one PDSCH of the one cell; and receiving data on the multiple PDSCHs of the multiple cells in case that the DCI format schedules the multiple PDSCHs of the multiple cells, wherein an indicator included in the DCI format indicates scheduled cells corresponding to the multiple cells in case that the DCI format schedules the multiple PDSCHs of the multiple cells, wherein a bandwidth part (BWP) indicator included in the DCI format is applicable to the scheduled cells in case that the DCI format schedules the multiple PDSCHs of the multiple cells, the BWP indicator corresponding to an ascending order of a BWP identifier, wherein a rate matching indicator (RMI) included in the DCI format indicates a rate matching value to be used on active BWPs of the scheduled cells in case that the DCI format schedules the multiple PDSCHs of the multiple cells, and wherein a zero power channel state information-reference signal (ZP CSI-RS) trigger indicator included in the DCI format indicates a CSI-RS value to be used on the active BWPs of the scheduled cells in case that the DCI format schedules the multiple PDSCHs of the multiple cells.
