Abstract
A technique for controlling a cluster of radio access nodes for radio communication with a user equipment is described. As to a method (200) aspect of the technique, information is received (202) from at least one of the user equipment and the radio access nodes, wherein the information is the cluster indicative of a radio quality (904-908) of the radio communication. Based on the received information, a number of radio access nodes that redundantly communicate with the user equipment is changed (204).
Claims22
A method of controlling a cluster of radio access nodes for radio communication with a user equipment, the method comprising:
- receiving information indicative of a radio quality of the radio communication supported by at least first and second subsets of the radio access nodes;
- and
- changing, based on the received information, a number of the radio access nodes in the first subset and/or the second subset, each of the radio access nodes in the first subset being configured to exchange, with the user equipment, corresponding or identical data packets relative to each of the other radio access nodes in the first subset, and each of the radio access nodes in the second subset being configured to exchange, with the user equipment, different data packets relative to each of the other radio access nodes in the second subset;
- wherein the changing includes switching, based on the received information, between a robustness-oriented mode of operating the cluster and a throughput-oriented mode of operating the cluster,
- wherein in the robustness-oriented mode a same copy of a data packet is transmitted to all of the at least two radio access nodes within the cluster,
- wherein in the throughput-oriented mode different data packets are transmitted to the radio access nodes within the cluster, and
- wherein the radio communication of at least some of the radio access nodes uses a millimeter wavelength band, an Extremely High Frequency band, or a frequency in the range of 15 GHz to 100 GHz.
A non-transitory computer readable recording medium storing a computer program product for controlling a cluster of radio access nodes for radio communication with a user equipment, the computer program product comprising software instructions which, when run on processing circuitry of a computing device, causes the computing device to:
- receive information indicative of a radio quality of the radio communication supported by at least first and second subsets of the radio access nodes;
- and
- change, based on the received information, a number of the radio access nodes in the first subset and/or the second subset, each of the radio access nodes in the first subset being configured to exchange, with the user equipment, corresponding or identical data packets relative to each of the other radio access nodes in the first subset, and each of the radio access nodes in the second subset being configured to exchange, with the user equipment, different data packets relative to each of the other radio access nodes in the second subset,
- wherein the change includes switching, based on the received information, between a robustness-oriented mode of operating the cluster and a throughput-oriented mode of operating the cluster,
- wherein in the robustness-oriented mode a same copy of a data packet is transmitted to all of the at least two radio access nodes within the cluster,
- wherein in the throughput-oriented mode different data packets are transmitted to the radio access nodes within the cluster, and
- wherein the radio communication of at least some of the radio access nodes uses a millimeter wavelength band, an Extremely High Frequency band, or a frequency in the range of 15 GHz to 100 GHz.
A device for controlling a cluster of radio access nodes for radio communication with a user equipment, the device comprising:
- processing circuitry;
- memory containing instructions executable by the processing circuitry whereby the device is operative to:
- receive information indicative of a radio quality of the radio communication;
- and
- change, based on the received information, a number of the radio access nodes in the first subset and/or the second subset, each of the radio access nodes in the first subset being configured to exchange, with the user equipment, corresponding or identical data packets relative to each of the other radio access nodes in the first subset, and each of the radio access nodes in the second subset being configured to exchange, with the user equipment, different data packets relative to each of the other radio access nodes in the second subset,
- wherein the change includes switching, based on the received information, between a robustness-oriented mode of operating the cluster and a throughput-oriented mode of operating the cluster,
- wherein in the robustness-oriented mode a same copy of a data packet is transmitted to all of the at least two radio access nodes within the cluster,
- wherein in the throughput-oriented mode different data packets are transmitted to the radio access nodes within the cluster, and
- wherein the radio communication of at least some of the radio access nodes uses a millimeter wavelength band, an Extremely High Frequency band, or a frequency in the range of 15 GHz to 100 GHz.
