Abstract
A 5G gNodeB has a Centralized Unit (CU) and one or more Distributed Units (DU). Each of the one or more DUs has a cell topology information that it sends to the CU so that the CU has information for each DU for each of the DU's cells, including which cells are available to each primary cell for carrier aggregation. When a UE connects to the CU, the CU queries its configuration information—including cell topology information for the DU connected to the UE— to determine if and which secondary cells are available for carrier aggregation. If so, the CU may signal the DU to configure and subsequently activate the one or more secondary cells to which the UE can connect for carrier aggregation.
Claims17
A method for configuring a UE (User Equipment) for carrier aggregation in a 5G gNodeB, comprising:
- receiving cell topology information from a DU (Distributed Unit), the cell topology information corresponding to a plurality of cells coupled to the DU, the cell topology information including, for each of the plurality of cells, information relating to each of one or more candidate secondary cells corresponding to each of the plurality of cells;
- storing the cell topology information;
- and
- allocating at least one candidate secondary serving cell to the UE based on the stored cell topology information related to the at least one candidate secondary serving cell, aggregate throughput, and capabilities of the UE.
A 5G gNodeB, capable of configuring a UE (User Equipment) for carrier aggregation, comprising:
- one or more processors;
- and
- one or more non-transitory memory devices having stored therein machine readable instructions that, when executed by the one or more processors, cause the 5G gNodeB to:
- receive cell topology information from a DU (Distributed Unit), the cell topology information corresponding to a plurality of cells coupled to the DU, the cell topology information including, for each of the plurality of cells, information relating to each of one or more candidate secondary cells corresponding to each of the plurality of cells;
- store the cell topology information;
- and
- allocate at least one candidate secondary serving cell to the UE based on the stored cell topology information related to the at least one candidate secondary serving cell, aggregate throughput, and capabilities of the UE.
