Samsung patents method to reduce data load in 5G base stations
Samsung describes a radio unit that uses a mathematical trick called random embedding to shrink the size of signal data before sending it to a central processor. By reducing the number of data points, the device lowers the amount of information that needs to be transmitted over the internal network connection.
In the filing’s own words
A radio unit (RU) device is provided. The device includes a radio frequency (RF) transceiver, a fronthaul transceiver, memory, comprising one or more storage media, for storing instructions, and one or more processors communicatively coupled to the RF transceiver, the fronthaul transceiver and the memory, wherein the instructions, when executed by the one or more processors individually or collectively, cause the device to obtain reference signals via the RF transceiver, obtain a transformed covariance matrix of the reference signals with respect to noise and interference through random embedding for dimensionality reduction, obtain an extraction matrix through the subspace decomposition of the transformed covariance matrix, perform pre-combining using the extraction matrix to pre-combine uplink signals acquired via the RF transceiver, and transmit data of the pre-combined uplink signals to a digital unit (DU) via the fronthaul transceiver, and wherein the random embedding is used to transform a first dimension of the number of reception layers of the RU into a second dimension of a number smaller than the number of reception layers.
What exactly they claim (claim 1)
1. A device of a radio unit (RU), the device comprising: a radio frequency (RF) transceiver; a fronthaul transceiver; memory, comprising one or more storage media, storing instructions; and one or more processors communicatively coupled to the RF transceiver, the fronthaul transceiver and the memory, wherein the instructions, when executed by the one or more processors individually or collectively, cause the device to: obtain reference signals through the RF transceiver, obtain a transform covariance matrix for noise and interference of the reference signals through random embedding for dimensionality reduction, obtain an extraction matrix through subspace decomposition of the transformation covariance matrix, perform pre-combining using the extraction matrix to uplink signals obtained through the RF transceiver, and transmit, through the fronthaul transceiver to a digital unit (DU), data of the uplink signals on which the pre-combining is performed, and wherein the random embedding is used to transform a first dimension with the number of receiving layers of the RU into a second dimension with a number less than the number of receiving layers.
