Abstract

A system can configure a first number of demodulation reference signal (DMRS) positions in radio resource control information as part of a connection setup with a user equipment that is configured to facilitate broadband cellular communications, wherein the broadband cellular communications are facilitated with carrier aggregation of a primary cell and a secondary cell. The system can, after attaching to the user equipment, send a first message to the user equipment indicative of modifying the first number of DMRS positions to a second number of demodulation reference signal positions for first communications via the primary cell. The system can send a second message to the user equipment indicative of modifying the DMRS positions for second communications via the secondary cell. The system can conduct the broadband cellular communications with the user equipment according to the second number of DMRS positions.

Dependent claims

A system, comprising:

at least one processor;
and
at least one memory coupled to the at least one processor, comprising instructions that cause the at least one processor to perform operations comprising:
configuring a first number of demodulation reference signal positions in radio resource control information as part of a connection setup with a base station that is configured to facilitate broadband cellular communications, wherein the broadband cellular communications are facilitated with carrier aggregation of a primary cell and a secondary cell into a master cell group, wherein the carrier aggregation comprises combining respective bandwidth of the primary cell and the secondary cell into a combined bandwidth that is utilized by the system, wherein the system initially registers with the master cell group that comprises the primary cell and the secondary cell, wherein the primary cell comprises a first device, and wherein the secondary cell comprises a second device;
after attaching to the base station, receiving a first message from the base station indicative of modifying the first number of demodulation reference signal positions to a second number of demodulation reference signal positions for communications via the primary cell;
receiving a second message from the base station indicative of modifying the first number of demodulation reference signal positions to the second number of demodulation reference signal positions for communications via the secondary cell;
and
conducting the broadband cellular communications with the base station according to the second number of demodulation reference signal positions, wherein a throughput of the broadband cellular communications is determined as a function of a size of a transport block set based on the second number of demodulation reference signal positions.
