Wireless mesh network
Among other things, aspects, features, and implementations of wireless mesh networks and wireless mesh network devices are described.
1. A wireless mesh network comprising
a radio node coupled to a core network, and
a mesh node configured to receive a downlink transmission from the radio node on a first antenna panel and to transmit on the downlink on an access link or a downstream backhaul link on a second antenna panel on overlapping time resources, the mesh node comprising a self-interference module to estimate and to cancel at least part of the interference of the downlink transmission to the downlink reception, the mesh node scheduling the downlink transmission on the second antenna panel independently from the scheduling by the radio node of the downlink transmission received by the first antenna panel.
2. The wireless mesh network of claim 1 in which the mesh node cancels the interference only in the digital domain.
3. The wireless mesh network of claim 1 in which the mesh node maintains information about prohibited beam pairs and determines prohibited beam pairs by measuring the self-interference level on the first antenna panel using a first antenna beam when transmitting on the second antenna panel using a second antenna beam.
4. The wireless mesh network of claim 3 in which the mesh node refrains from scheduling a downlink transmission using a second beam on the second antenna panel on the same time resource as for an expected first beam on a first antenna panel when the first and second beams correspond to a prohibited beam pair.
5. The wireless mesh network of claim 1 in which the mesh node transmits downlink transmissions on an access link on the first antenna panel on a different time resource based on downlink control messages received from the radio node.
6. A wireless mesh network comprising
a first radio node and a second radio node coupled to the core network,
a first mesh node and a second mesh node linked respectively to the first radio node and the second radio node,
the first mesh node and the second mesh node scheduling transmissions respectively to a first user device and a second user device, and
the first mesh node estimating the likelihood of cross-link interference from the second radio node, and
the first mesh node transmits to the first user device on a designated time resource and frequency resource with a probability determined based on the estimated likelihood of cross-link interference.
7. The wireless mesh network of claim 6 in which the designated time resource is free of cross-link interference from the second mesh node.
8. The wireless mesh network of claim 6 in which the first mesh node determines the likelihood of cross-link interference based on beam measurements with the second mesh node.
9. The wireless mesh network of claim 6 in which the first mesh node determines the likelihood of cross-link interference based on HARQ feedback received from the first user device.
10. The wireless mesh network of claim 6 in which the first mesh node determines the likelihood of cross-link interference based on a DL load or a UL load of the second mesh node.
11. The wireless mesh network of claim 6 in which the first mesh node determines the likelihood of cross-link interference based on an estimate of the location of the first user device.
12. A wireless mesh network of claim 6 in which the likelihood of cross-link interference is determined using machine learning.
13. A wireless mesh network comprising
a radio node coupled to a core network,
a mesh node configured to transmit an uplink transmission to the radio node on a first antenna panel and to receive on the uplink on an access link or a downstream backhaul link on a second antenna panel on overlapping time resources, the mesh node comprising a self-interference module to estimate and to cancel at least part of the interference of the uplink transmission to the uplink reception, the mesh node scheduling the uplink reception on the second antenna panel independently from the scheduling by the radio node of the uplink transmission by the first antenna panel.
14. The wireless mesh network of claim 13 in which the mesh node maintains information about prohibited beam pairs and determines prohibited beam pairs by measuring the self-interference level on the first antenna panel using a first antenna beam when transmitting on the second antenna panel using a second antenna beam.
15. The wireless mesh network of claim 13 in which the mesh node refrains from scheduling an uplink reception using a second beam on the second antenna panel on the same time resource as for an expected first beam on a first antenna panel when the first and second beams correspond to a prohibited beam pair.
16. The wireless mesh network of claim 13 in which the mesh node receives uplink transmissions on an access link on the first antenna panel on a different time resource based on uplink control messages received from the radio node.
