Abstract
There is disclosed a method of operating a feedback radio node in a wireless communication network. The method of operating a feedback radio node in a wireless communication network may include monitoring a first search space associated to a first type of control information based on operation pertaining to a second search space associated to a second type of control information. The first type of control information may pertain to a first signalling format for control information, and/or the second type of control information may pertain to a second signalling format for control information. The disclosure also pertains to related devices and methods, in particular to a feedback radio node, a method of operating a signalling radio node and a signalling radio node.
Claims20
A method of operating a feedback radio node in a wireless communication network, the method comprising:
- monitoring a first search space associated to a first type of control information based on operation pertaining to one or both reception of and monitoring for a second type of control information in a second search space;
- and
- triggering a fallback to the first search space based on the reception of control information in the second search space.
A non-transitory computer storage medium storing a computer program comprising instructions causing processing circuitry to one or both control and perform a method, the method comprising:
- monitoring a first search space associated to a first type of control information based on operation pertaining to one or both reception of and monitoring for a second type of control information in a second search space;
- and
- triggering a fallback to the first search space based on the reception of control information in the second search space.
A feedback radio node for a wireless communication network, the feedback radio node configured to:
- monitor a first search space associated to a first type of control information based on operation pertaining to one or both reception of and monitoring for a second type of control information in a second search space;
- and
- trigger a fallback to the first search space based on the reception of control information in the second search space.
A method of operating a signalling radio node in a wireless communication network, the method comprising:
- configuring a feedback radio node with a condition configuration, the condition configuration indicating one or more conditions for the feedback radio node for monitoring a first search space associated to a first type of control information based on operation pertaining to one or both transmission of and monitoring for a second search space associated to a second type of control information;
- and
- determining a fallback based on the transmission of control information in the first search space.
A signalling radio node for a wireless communication network, the signalling radio node:
- configure a feedback radio node with a condition configuration, the condition configuration indicating one or more conditions for the feedback radio node for monitoring a first search space associated to a first type of control information based on operation pertaining to one or both transmission of and monitoring for a second search space associated to a second type of control information;
- and
- determine a fallback based on the transmission of control information in the first search space.
