Sounding reference signal transmission optimization with carrier aggregation

A method, comprising:

• as part of broadband cellular communications with user equipment, sending, by a system comprising at least one processor, a radio resource control message to the user equipment to establish a periodic sounding reference signal mode for the broadband cellular communications, wherein the broadband cellular communications are facilitated with carrier aggregation of a primary cell and a secondary cell, and wherein the radio resource control message is sent to the user equipment from a centralized unit;
• sending, by the system, a second message in a second format to the user equipment, wherein the second format differs from a radio request control format, wherein the second message indicates modifying a number of sounding reference signal positions for first communications via the primary cell, wherein the second message is sent to the user equipment from a distributed unit, and wherein a first amount of time associated with sending the user equipment the radio resource control message from the centralized unit is greater than a second amount of time associated with sending the user equipment the second message from the distributed unit;
• sending, by the system, a third message in the second format to the user equipment, wherein the third message indicates the modifying of the number of sounding reference signal positions for second communications via the secondary cell;
• receiving, by the system and from the user equipment, a fourth message that utilizes the number of sounding reference signal positions to convey sounding reference signal information;
• and
• saving, by the system, an indication of a channel quality that corresponds to the broadband cellular communications based on the sounding reference signal information in the fourth message.

A non-transitory computer-readable medium comprising instructions that, in response to execution, cause a system comprising at least one processor to perform operations, comprising:

• sending, to a user equipment, a first message in a first format to establish a sounding reference signal mode for broadband cellular communications with the user equipment via a primary cell and a secondary cell, wherein the first message is sent to the user equipment from a centralized unit;
• sending, to the user equipment, a second message in a second format, wherein the first format differs from the second format, wherein the second message indicates modifying a number of sounding reference signal positions for communications via the primary cell, wherein the second message is sent to the user equipment from a distributed unit, and wherein a first amount of time associated with sending the user equipment the first message from the centralized unit is greater than a second amount of time associated with sending the user equipment the second message from the distributed unit;
• sending, to the user equipment, a third message in the second format, wherein the third message indicates the modifying of the number of sounding reference signal positions for communications via the secondary cell;
• receiving, from the user equipment, a fourth message that utilizes the number of sounding reference signal positions to convey sounding reference signal information;
• and
• saving an indication of a channel quality that corresponds to the broadband cellular communications based on the sounding reference signal information in the fourth message.
