Abstract
A system and method for managing a Physical Downlink Control Channel (PDCCH) in a Radio Access Network (RAN) involves dynamically determining a PDCCH symbol count in a subframe based on the RAN state, setting the PDCCH symbol count for the subframe accordingly, and transmitting the subframe. The method further includes aligning the determined PDCCH symbol count across a cluster of sites and bands. The PDCCH symbol count is an integer greater than zero and less than four, ensuring efficient and optimized PDCCH management within the RAN environment such as a 4G or 5G cellular RAN.

A computer-implemented method for managing a Physical Downlink Control Channel (PDCCH) in a Radio Access Network (RAN), the method comprising:
- dynamically determining a PDCCH symbol count in a subframe based on a RAN state of a target User Equipment (UE);
- setting the PDCCH symbol count for the subframe to the determined PDCCH symbol count;
- transmitting the subframe, wherein the PDCCH symbol count comprises an integer greater than zero and less than four, and the setting responds in near real-time to changes in the RAN state;
- and
- aligning the determined PDCCH symbol count across a cluster comprising a plurality of sites and bands.
A computer-implemented method for managing a Physical Downlink Control Channel (PDCCH) in a Radio Access Network (RAN), the method comprising:
- dynamically determining a PDCCH symbol count in a subframe based on a RAN state of a target User Equipment (UE);
- setting the PDCCH symbol count for the subframe to the determined PDCCH symbol count;
- and
- transmitting the subframe, wherein the PDCCH symbol count comprises an integer greater than zero and less than four, and the setting responds in near real-time to changes in the RAN state;
- wherein the RAN state comprises a congestion state that indicates congestion at a site of the RAN and the setting sets the PDCCH symbol count to 1;
- and
- wherein the congestion state indicates congestion when a scheduler for the subframe observes a queuing delay above a threshold delay.
A system to manage a Physical Downlink Control Channel (PDCCH) in a Radio Access Network (RAN), the system comprising:
- a PDCCH module to dynamically determine a PDCCH symbol count in a subframe based on a RAN state of a target User Equipment (UE), and to set the PDCCH symbol count for the subframe to the determined PDCCH symbol count;
- and
- a transmitter to transmit the subframe,
- wherein the PDCCH symbol count comprises an integer greater than zero and less than four, and the PDCCH module responds in near real-time to changes in the RAN state;
- and
- wherein the RAN state comprises a bandwidth of a transmission band, the setting sets the PDCCH symbol count to 2 when the bandwidth is less than 10 MHz, and the setting sets the PDCCH symbol count to 1 when the bandwidth is greater than or equal to 10 MHz.
