Abstract
The present disclosure relates to a network node, a user device and corresponding methods for transmitting information from a network node to a group of user devices selected for transmission or reception of data in the same or partially overlapping set of radio resources comprising group control information common to the selected group of user devices and user device control information specific to individual user devices.
Claims25
A network node for a wireless communication system, the network node comprising:
- a processor configured to
- select a group of user devices for superposed reception or transmission of data,
- determine control information (CI) for the user devices of the selected group, the control information (CI) comprising group control information (GCI) common to the user devices of the selected group and at least one user device control information (UDCI) specific to at least one user device of the user devices of the selected group;
- and
- a transceiver configured to
- transmit a first signal which is addressed to the user devices of the selected group in a first set of time and frequency resources, the first signal comprising the group control information (GCI) and the user device control information (UDCI);
- or
- transmit a first signal which is addressed to the user devices of the selected group in a first set of time and frequency resources, the first signal comprising the group control information (GCI), and transmit a second signal which is addressed to at least one user device of the user devices of the selected group in a second set of time and frequency resources, the second signal comprising the user device control information (UDCI).

A user device for a wireless communication system, the user device comprising:
- a transceiver configured to receive a first signal in a first set of time and frequency resources, the first signal comprising group control information (GCI) common to a selected group of user devices and user device control information (UDCI) specific to the user device;
- or
- receive a first signal in a first set of time and frequency resources, the first signal comprising the group control information (GCI), and receive a second signal in a second set of time and frequency resources, the second signal comprising the user device control information (UDCI);
- and
- a processor configured to
- decode the group control information (GCI) and the user device control information (UDCI);
- and
- wherein the transceiver further is configured to receive or transmit data according to the group control information (GCI) and the user device control information (UDCI).
5 more elements
A method in a network node, the method comprising:
- selecting a group of user devices for superposed reception or transmission of data;
- determining control information (CI) for the user devices of the selected group, the control information (CI) comprising group control information (GCI) common to the user devices of the selected group and at least one user device control information (UDCI) specific to at least one user device of the user devices of the selected group;
- and
- one of:
- transmitting a first signal which is addressed to the user devices of the selected group in a first set of time and frequency resources, the first signal comprising the group control information (GCI) and the user device control information (UDCI);
- and
- transmitting a first signal which is addressed to the user devices of the selected group in a first set of time and frequency resources, the first signal comprising the group control information (GCI), and transmitting a second signal which is addressed to at least one user device of the user devices of the selected group in a second set of time and frequency resources, the second signal comprising the user device control information (UDCI).
4 more elements
A method in a user device, the method comprising:
- receiving one of:
- a first signal in a first set of time and frequency resources, the first signal comprising group control information (GCI) common to a selected group of user devices and user device control information (UDCI) specific to the user device;
- and
- a first signal in a first set of time and frequency resources, the first signal comprising the group control information (GCI), and receiving a second signal in a second set of time and frequency resources, the second signal comprising the user device control information (UDCI);
- decoding the group control information (GCI) and the user device control information (UDCI);
- receiving or transmitting data according to the group control information (GCI) and the user device control information (UDCI).
3 more elements
A non-transitory computer readable medium having stored thereon computer-executable instructions that when executed by a processor cause the processor to perform operations in a network node, the operations comprising:
- selecting a group of user devices for superposed reception or transmission of data;
- determining control information (CI) for the user devices of the selected group, the control information (CI) comprising group control information (GCI) common to the user devices of the selected group and at least one user device control information (UDCI) specific to at least one user device of the user devices of the selected group;
- transmitting one of
- a first signal which is addressed to the user devices of the selected group in a first set of time and frequency resources, the first signal comprising the group control information (GCI) and the user device control information (UDCI);
- and
- a first signal which is addressed to the user devices of the selected group in a first set of time and frequency resources, the first signal comprising the group control information (GCI), and transmitting a second signal which is addressed to at least one user device of the user devices of the selected group in a second set of time and frequency resources, the second signal comprising the user device control information (UDCI).
