CENTRAL NETWORK NODE, FIRST NETWORK NODE, FIRST WIRELESS DEVICE, CONTROLLER NETWORK NODE, AND METHODS THEREIN, OF INSTRUCTING THE FIRST NETWORK NODE TO TRANSMIT TO THE FIRST WIRELESS DEVICE

摘要

A method performed by a central network node of instructing one of a first network node and a second network node to transmit to a first wireless device, wherein all operate in a combined cell deployment. The central network node receives a first Channel Quality Indicator, CQI, and a third CQI sent by the first wireless device. The first CQI has been computed by the first wireless device based on a first unique signal transmitted by the first network node. The third CQI has been computed by the first wireless device based on a second unique signal transmitted by the second network node. The central network node identifies the one of the first and the second network nodes having a better channel quality, based on the received first CQI and the third CQI. The central network node sends a first message to the identified network node, instructing it to transmit to the first wireless device.

1. A method performed by a central network node of instructing one of a first network node and a second network node to transmit to a first wireless device, the central network node, the first network node, the second network node, and the first wireless device operating in a combined cell deployment in a wireless communications network, the method comprising:
receiving a first Channel Quality Indicator, CQI, and a third CQI sent by the first wireless device, wherein the first CQI has been computed by the first wireless device based on a first unique signal transmitted by the first network node, and the third CQI has been computed by the first wireless device based on a second unique signal transmitted by the second network node, identifying the one of the first network node and the second network node having a better channel quality to transmit to the first wireless device, based on the received first CQI and the third CQI, and sending a first message to the identified one of the first network node and the second network node having the better channel quality, the first message instructing the identified one of the first network node and the second network node to transmit to the first wireless device.
