Abstract
A communication network is informed of the availability of MIMO mode of communication of user equipment by receiving a transmitted (305) indicator of the availability of MIMO mode of communication of a user equipment via a feedback channel between the user equipment and a node of a communication network.
Claims23
A method of operating user equipment in a communication network to inform the communication network of the availability of MIMO mode of communication, the method comprising:
- determining the availability of MIMO mode of communication of the user equipment, independently, for each available frequency band;
- and
- transmitting an indicator indicating the determined availability of MIMO mode of communication of the user equipment, independently, for each available frequency band, via a feedback channel between the user equipment and a node of the communication network;
- wherein transmitting the indicator of the determined availability of MIMO mode of communication of the user equipment comprises transmitting a specific sequence of feedback information on the feedback channel.
A method of operating a node of a communication network to control mode of communication between the communication network and at least one user equipment, the method comprising:
- receiving, at the node of the communication network, an indicator of the availability of MIMO mode of communication of the at least one user equipment, independently, for each available frequency band via a feedback channel between the at least one user equipment and the node of the communication network, wherein the indicator comprises a specific sequence of feedback information;
- and
- controlling the MIMO mode of communication between the node of the communication network and the at least one user equipment, independently, for each available frequency band, in response to the received respective indicator.
A user equipment comprising:
- a multi-antenna;
- a transceiver configured to enable MIMO mode of communication between the user equipment and a node of a communication network via the multi-antenna;
- and
- a processor configured to determine the availability of MIMO mode of communication of the user equipment and to provide an indicator of the determined availability of MIMO mode of communication of the user equipment, independently, for each available frequency band;
- wherein the transceiver is further configured to transmit the indicator, independently, for each available frequency band via a feedback channel between the user equipment and the node of the communication network, wherein the indicator comprises a specific sequence of feedback information.
A node of a communication network comprising:
- a receiver configured to receive an indicator of the availability of MIMO mode of communication of at least one user equipment, independently, for each available frequency band via a feedback channel between the at least one user equipment and the node of the communication network, wherein the indicator comprises of specific sequence of feedback information;
- an interpreter configured to interpret the received indicator to determine the availability of MIMO mode of communication of the at least one user equipment, independently, for each available frequency band;
- and
- a controller configured to control the mode of communication between the node of the communication network and the at least one user equipment, independently, for each available frequency band, in response to the respective interpreted specific sequence of feedback information.
