Abstract

A system can configure a first number of demodulation reference signal (DMRS) positions as part of a connection setup with a user equipment that is configured to facilitate broadband cellular communications. The system can, after attaching the user equipment, send, to the user equipment, a first medium access control control element (MAC-CE) message indicative of modifying the first number of DMRS positions to a second number of DMRS positions for a primary cell. The system can, in response to determining that a secondary cell is activated with respect to the user equipment, send, to the user equipment, a second MAC-CE message indicative of modifying the first number of DMRS positions to the second number of demodulation reference signal positions for the secondary cell. The system can communicate with the user equipment according to the second number of DMRS positions.

Dependent claims

A system, comprising:

a processor;
and
a memory coupled to the processor, comprising instructions that cause the 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 user equipment that is configured to facilitate first broadband cellular communications;
after attaching the user equipment, sending, to the user equipment, a first medium access control control element message indicative of modifying the first number of demodulation reference signal positions to a second number of demodulation reference signal positions for a primary cell;
in response to determining that a secondary cell is activated with respect to the user equipment, sending, to the user equipment, a second medium access control control element message indicative of modifying the first number of demodulation reference signal positions to the second number of demodulation reference signal positions for the secondary cell;
and
communicating, via second broadband cellular communications, with the user equipment according to the second number of demodulation reference signal positions, wherein a throughput of the second 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.
