Samsung patents method for sharing data load info between 5G network parts
Samsung describes a system where one part of a 5G base station shares data waiting information with another part to help manage uplink traffic. The invention involves sending specific details about a user's data buffer to a secondary network unit to improve scheduling efficiency in carrier aggregation setups.
In the filing’s own words
A device of a first distributed unit (DU) is provided. The device includes memory, including one or more storage media, storing instructions and at least one processor, comprising processing circuitry, communicatively coupled to the memory, wherein the instructions, when executed by the at least one processor individually or collectively, cause the device to obtain information on a buffer status report (BSR) of a UE on a primary cell related to the first DU, and transmit, to a second DU related to a secondary cell (SCell) of carrier aggregation (CA) configured for the UE through an interface between the first DU and the second DU, a split BSR management message for uplink scheduling of a second DU, and wherein the split BSR management message includes the identifier (ID) of the UE, an index of the primary cell, information about a time at which the BSR is received, logical channel group (LCG) ID information about the BSR, and split buffer occupancy (BO) to be used by the second DU.
What exactly they claim (claim 1)
1. A device of a first distributed unit (DU), the device comprising: memory, comprising one or more storage media, storing instructions; and at least one processor, comprising processing circuitry, communicatively coupled to the memory, wherein the instructions, when executed by the at least one processor individually or collectively, cause the device to: obtain information on a buffer status report (BSR) of a user equipment (UE) on a primary cell (PCell) related to the first DU, and transmit, to a second DU related to a secondary cell (SCell) of carrier aggregation (CA) configured for the UE through an interface between the first DU and the second DU, a split BSR management message for uplink scheduling of the second DU, and wherein the split BSR management message comprises an identifier (ID) of the UE, an index of the PCell, time information when the BSR is received, logical channel group (LCG) ID information of the BSR, and split buffer occupancy (BO) to be used by the second DU.
