Sending a configuration message and reporting channel information on PUCCH in PCELL and in SCELL

A method performed by a second communication device for reporting channel information to a first communication device, the first communication device and the second communication device operating in a communications network, the method comprising:

• receiving a configuration message from the first communication device, the configuration message being for configuring the second communication device to report channel information about one carrier to the first communication device, the configuration message being for further configuring the second communication device to report the channel information alternatively on a primary carrier and on one or more secondary carriers,
• the information comprising a) channel information relating to one carrier, b) information relating to a primary carrier and one or more secondary carriers, on which the channel information of the one carrier is to be reported, c) information relating to a reporting time for each of the primary carrier and the one or more secondary carriers, the reporting time being for the second communication device to report the channel information;
• determining first channel information to be comprised in the first channel information report, according to the received configuration message;
• determining second channel information to be comprised in the second channel information report, according to the received configuration message;
• sending a first channel information report to the first communication device for the one carrier on the primary carrier, according to the received configuration message in a first time period (Tp1);
• and
• sending a second channel information report to the first communication device for the one carrier on a first secondary carrier of the one or more secondary carriers, according to the received configuration message in a second time period (Tp2).

A first communication device configured to send a configuration message to a second communication device, the first communication device and the second communication device being configured to operate in a communications network, the first communication device comprising:

• a processor;
• and
• a memory operatively coupled to the processor and comprising program instructions for execution by the processor, whereby the first communication device is configured to:
• determine information related to the configuration message, the information comprising:
• a) channel information relating to one carrier, b) information relating to a primary carrier and one or more secondary carriers, on which the channel information of the one carrier is to be reported, c) information relating to a reporting time for each of the primary carrier and the one or more secondary carriers, the reporting time being for the second communication device to report the channel information;
• and
• send the configuration message to the second communication device, the configuration message being configured to configure the second communication device to report the channel information about the one carrier to the first communication device, and the configuration message being configured to configure the second communication device to report the channel information about the one carrier alternatively on a primary carrier in a first time period (Tp1) and on one or more secondary carriers in a second time period (Tp2).

A second communication device configured to report channel information to a first communication device, the first communication device and the second communication device being configured to operate in a communications network, the second communication device comprising:

• a processor;
• and
• a memory operatively coupled to the processor and comprising program instructions for execution by the processor, whereby the first communication device is configured to:
• receive a configuration message from the first communication device, the configuration message being configured to configure the second communication device to report channel information about one carrier to the first communication device, the configuration message being configured to further configure the second communication device to report the channel information alternatively on a primary carrier and on one or more secondary carriers,
• the information comprising a) channel information relating to one carrier, b) information relating to a primary carrier and one or more secondary carriers, on which the channel information of the one carrier is to be reported, c) information relating to a reporting time for each of the primary carrier and the one or more secondary carriers, the reporting time being for the second communication device to report the channel information;
• determine first channel information to be comprised in the first channel information report, according to the received configuration message;
• determine second channel information to be comprised in the second channel information report, according to the received configuration message;
• send a first channel information report to the first communication device for the one carrier on the primary carrier, according to the received configuration message in a first time period (Tp1);
• and
• send a second channel information report to the first communication device for the one carrier on a first secondary carrier of the one or more secondary carriers, according to the received configuration message in a second time period (Tp2).
