a physical resource retransmission rate for a random-access channel,
a radio link failure rate,
a channel quality, and
a physical resource retransmission rate for hybrid automatic repeat request.
7. The system of claim 1, wherein choosing whether to replace the default coordinated multipoint set of neighboring base stations for the selected user equipment with the intermediate coordinated multipoint set of neighboring base stations comprises:
comparing, via the hardware processor, a throughput for the selected user equipment using the intermediate coordinated multipoint set of neighboring base stations with a throughput for the selected user equipment using the default coordinated multipoint set of neighboring base stations.
8. A coordinated multipoint set determination method, comprising:
obtaining serving base station information for a serving base station, and neighboring base station information for a plurality of neighboring base stations for the serving base station;
determining an initial coordinated multipoint region based on the neighboring base station information and the serving base station information;
identifying a default coordinated multipoint set of neighboring base stations for each user equipment associated with the serving base station;
selecting one of the user equipment associated with the serving base station as a candidate for coordinated multipoint set determination based on a throughput for the user equipment and at least one of:
an absolute location of the user equipment, and
a location of the user equipment relative to the serving base station;
identifying for the selected user equipment, a set of neighboring base station candidates based on distances between the selected user equipment and neighboring base stations;
identifying an intermediate coordinated multipoint set of neighboring base stations for the selected user equipment based on one or more wireless communication parameters;
choosing whether to replace the default coordinated multipoint set of neighboring base stations for the selected user equipment with the intermediate coordinated multipoint set of neighboring base stations; and
setting the chosen coordinated multipoint set of neighboring base stations as a final coordinated multipoint set for the selected user equipment for coordinated multipoint communication.
9. The method of claim 8, further comprising:
adjusting a coordinated multipoint region from the initial coordinated multipoint region based on a number of user equipment having a same final coordinated multipoint set.
10. The method of claim 8, further comprising:
determining whether to utilize coordinated scheduling or joint transmission for coordinated multipoint communication for the selected user equipment; and
transmitting a data packet to the selected user equipment using the determined coordinated scheduling or joint transmission.
11. The method of claim 8, wherein determining the initial coordinated multipoint region comprises:
determining an intersecting coverage area for the serving base station and the plurality of neighboring base stations for the serving base station.
