Abstract
There is disclosed a method of operating an Integrated Access and Backhaul, IAB, parent node for a wireless communication network. The method includes transmitting, to an Integrated Access and Backhaul, IAB, child node, an indication of the availability of soft frequency resources. The disclosure also pertains to related methods and devices, e.g. pertaining to an Integrated Access and Backhaul child node, or a program product.
Claims17
A method of operating an IAB parent node for a wireless communication network, the method comprising:
- partitioning one or both of transmission and reception resources of a cell into multiple resource block groups, RBGs;
- and
- transmitting, to an IAB child node, an indication of the availability of soft frequency resources, the indication indicating a frequency domain soft resource RBG of the multiple RBGs by using a distributed unit RGB identity, DU-RBG-ID.
An IAB parent node for a wireless communication network, the IAB parent node comprising processing circuitry configured to:
- partition one or both of transmission and reception resources of a cell into multiple resource block groups, RBGs;
- and
- transmit, to an IAB child node, an indication of the availability of soft frequency resources, the indication indicating a frequency domain soft resource RBG of the multiple RBGs by using a distributed unit RGB identity, DU-RBG-ID.
A method of operating an IAB child node for a wireless communication network, the method comprising:
- communicating utilising soft frequency resources based on a received indication of the availability of the soft frequency resources, the indication indicating a frequency domain soft resource resource block groups, RBGs, of multiple RBGs by using a distributed unit RGB identity, DU-RBG-ID, one or both of transmission and reception resources of a cell being partitioned into the multiple RBGs.
An IAB child node for a wireless communication network, the IAB child node comprising processing circuitry configured to:
- communicate utilising soft frequency resources based on a received indication of the availability of the soft frequency resources, the indication indicating a frequency domain soft resource resource block groups, RBGs, of multiple RBGs by using a distributed unit RGB identity, DU-RBG-ID, one or both of transmission and reception resources of a cell being partitioned into the multiple RBGs.
A non-transitory computer storage medium storing a computer program comprising instructions configured to cause processing circuitry to one or both control and perform a method of operating an IAB parent node for a wireless communication network, the method comprising:
- partitioning one or both of transmission and reception resources of a cell into multiple resource block groups, RBGs;
- and
- transmitting, to an IAB child node, an indication of the availability of soft frequency resources, the indication indicating a frequency domain soft resource RBG of the multiple RBGs by using a distributed unit RGB identity, DU-RBG-ID.
