1. A system comprising:
a first Base Station (BS) in a first cell; and
a second BS in the first cell, wherein the first BS and the second BS belong to the same mobile network operator and are disposed at predetermined locations of the first cell, wherein the first cell is a geographical area comprising an interior region having a predetermined area surrounding a center of the first cell and a first exterior region comprising at least a portion of a remainder of the first cell, the first cell having a first region comprising a first part of the interior region and a first part of the first exterior region; and a second region comprising a second part of the interior region and a second part of the first exterior region, wherein the second region has an overlapping boundary with the first region, wherein the first BS and the second BS each comprises a first antenna to service the first region and a second antenna to service the second region, wherein the first BS is to:
send downlink signals through the first antenna of the first BS to a User Equipment (UE) in the first part of the interior region in a first band of a frequency spectrum; and
send downlink signals through the first antenna of the first BS to a User Equipment (UE) in the first part of the first exterior region in a second band of the frequency spectrum; and
send downlink signals through the second antenna of the first BS to a User Equipment (UE) in the second part of the interior region in a third band of a frequency spectrum; and
send downlink signals through the second antenna of the first BS to a User Equipment (UE) in the second part of the first exterior region in the second band of a frequency spectrum; and, wherein the second BS is to:
send downlink signals through the first antenna of the second BS to a User Equipment (UE) in the first part of the interior region in the first band of a frequency spectrum; and
send downlink signals through the first antenna of the second BS to a User Equipment (UE) in the first part of the first exterior region in the second band of a frequency spectrum; and
send downlink signals through the second antenna of the second BS to a User Equipment (UE) in the second part of the interior region in the third band of a frequency spectrum; and
send downlink signals through the second antenna of the second BS to a User Equipment (UE) in the second part of the first exterior region in the second band of a frequency spectrum; and
wherein the first BS and the second BS are configured to send the downlink signals in the first band of the frequency spectrum at the same time without blanking, send the downlink signals in the second band of the frequency spectrum at the same time without blanking, and send the downlink signals in the third band of the frequency spectrum at the same time without blanking.
