User equipment configuration determination

A base station for user equipment, UE, configuration determination for a UE connected in a radio communication network, the base station, BS, comprising:

• a processing circuitry and a computer program product storing instructions that, when executed by the processing circuitry, causes the BS to:
• determine a minimum candidate user equipment configuration, CUEC, wherein the CUEC comprises a special cell, SpCell, the SpCell providing connection with the UE, wherein the SpCell is a primary cell, PCell, or a primary cell in a secondary cell group, PSCell, and wherein the SpCell in the minimum CUEC uses a minimum number of downlink, DL, and uplink, UL, multiple input multiple output, MIMO, layers supported by the SpCell;
• validate the determined minimum CUEC against capabilities of the UE;
• select a successfully validated determined minimum CUEC as a current CUEC;
• generate a next CUEC and compare the generated next CUEC with the current CUEC;
• validate the next CUEC against the capabilities of the UE when the next CUEC has a higher weight than the current CUEC, wherein the weight of each CUEC is determined by one or more of an estimation of maximum data rate, cell load, and channel quality;
• select a successfully validated next CUEC as the current CUEC;
• and
• configure the UE in accordance with the current CUEC.

A distributed unit for user equipment, UE, configuration determination for a UE connected in a radio communication network, the distributed unit, DU, comprising:

• a processing circuitry and a computer program product storing instructions that, when executed by the processing circuitry, causes the DU to:
• determine a minimum candidate user equipment configuration, CUEC, wherein the CUEC comprises a special cell, SpCell, the SpCell providing connection with the UE, wherein the SpCell is a primary cell, PCell, or a primary cell in a secondary cell group, PSCell, and wherein the SpCell in the minimum CUEC uses a minimum number of downlink, DL, and uplink, UL, multiple input multiple output, MIMO, layers supported by the SpCell;
• validate the determined minimum CUEC against capabilities of the UE;
• select a successfully validated determined minimum CUEC as a current CUEC;
• generate a next CUEC and compare the generated next CUEC with the current CUEC;
• validate the next CUEC against the capabilities of the UE when the next CUEC has a higher weight than the current CUEC, wherein the weight of each CUEC is determined by one or more of an estimation of maximum data rate, cell load, and channel quality;
• select a successfully validated next CUEC as the current CUEC;
• and
• configure the UE in accordance with the current CUEC.

A non-transitory computer readable medium comprising instructions executable by processing circuitry of a base station for user equipment, UE, configuration determination for a UE connected in a radio communication network, whereby the base station is operable to:

• determine a minimum candidate user equipment configuration, CUEC, wherein the CUEC comprises a special cell, SpCell, the SpCell providing connection with for the UE, wherein the SpCell is a primary cell, PCell, or a primary cell in a secondary cell group, PSCell, and wherein the SpCell in the minimum CUEC uses a minimum number of downlink, DL, and uplink, UL, multiple input multiple output, MIMO, layers supported by the SpCell;
• validate the determined minimum CUEC against capabilities of the UE;
• select a successfully validated determined minimum CUEC as a current CUEC;
• generate a next CUEC and compare the generated next CUEC with the current CUEC;
• validate the next CUEC against the capabilities of the UE when the next CUEC has a higher weight than the current CUEC, wherein the weight of each CUEC is determined by one or more of an estimation of maximum data rate, cell load, and channel quality;
• select a successfully validated next CUEC as the current CUEC;
• and
• configure the UE in accordance with the current CUEC.
