Samsung patents method for organizing wireless antenna signals
This patent describes a way for a cell tower to tell a phone exactly where to find specific reference signals used to measure network quality. The tower calculates the size and shape of signal groups based on its antennas and sends this layout information to the device.
In the filing’s own words
Methods and apparatuses for channel state information reference signal in wireless communication systems are provided. The methods of BS comprise: identifying first information corresponding to a number of antenna ports associated with transmissions of CSI-RSs; identifying, a first size of CDM groups associated with the number of antenna ports and a first shape of the CDM groups; identifying second information from the first information; identifying a starting SC index and a starting symbol index; identifying, based on the number of antenna ports associated with a CSI-RS transmission and a predetermined frequency domain granularity of channel state information, a size of RB cluster for the resource allocation; and transmitting, to a UE, resource configuration information indicating at least one of the size of RB cluster, the first size of the CDM groups, the first shape of the CDM groups, the starting SC index, and the starting symbol index.
What exactly they claim (claim 1)
1. A base station (BS) in a wireless communication system, the BS comprising: a processor configured to: identify first information corresponding to a number of antenna ports associated with transmissions of channel state information-reference signals (CSI-RSs), identify, based on channel coherence information, a first size of code division multiplexing (CDM) groups associated with the number of antenna ports and a first shape of the CDM groups, identify, based on the first size and the first shape of the CDM groups, second information from the first information, identify, based on the second information, a starting subcarrier (SC) index and a starting symbol index for a resource allocation, identify, based on the number of antenna ports associated with a CSI-RS transmission and a predetermined frequency domain granularity of channel state information, a size of resource block (RB) cluster for the resource allocation; and a transceiver operably coupled to the processor, the transceiver configured to transmit, to a user equipment (UE), resource configuration information indicating at least one of the size of RB cluster, the first size of the CDM groups, the first shape of the CDM groups, the starting SC index, and the starting symbol index.
