The present disclosure relates to an electronic apparatus, a wireless communication method and a computer-readable medium. The electronic apparatus for wireless communication according to one embodiment comprises a processing circuit. The processing circuit is configured to perform control to send or receive configuration information. The configuration information is related to configuration of a reference signal used in a discovery process of an integrated access backhaul (IAB) link node.
1. An electronic device for wireless communication, comprising processing circuitry configured to:
perform control to transmit or receive configuration information related to configuration of a reference signal for a discovery process of an Integrated Access and Backhaul link (IAB) node,
wherein, based on the reference signal comprises Synchronization Signal Block (SSBs):
the configuration information comprises a multiplexing manner of a SSB for an access link and a SSB for a first backhaul link, and
the multiplexing manner comprises at least one of:
applying different power levels to the SSB for the access link and the SSB for the first backhaul link, or
setting a specific SSB resource position as the SSB for the access link, and
wherein, based on the reference signal comprising Channel State Information Reference Signal (CSI-RSs):
the configuration information comprises a multiplexing manner of a CSI-RS for an access link and a CSI-RS for a second backhaul link, and
the multiplexing manner comprises transmitting the CSI-RS for the second backhaul link in an omnidirectional mode, and adopting orthogonal time-frequency resources for the CSI-RS for the access link and the CSI-RS for the second backhaul link.
2. An electronic device for wireless communication, comprising processing circuitry configured to:
determine, based on a time offset between signals of different nodes connected via a backhaul link, an adjustment of synchronization time for at least one node of the different nodes,
wherein the adjustment comprises:
in a case that an offset between a Synchronization Signal Block (SSB) for a superior node and a SSB for a subordinate node which are connected via a first backhaul link exceeds a predetermined threshold, adjusting synchronization time for the subordinate node,
in a case that an offset between a SSB from a first node and a SSB from a third node which are received by a second node is greater than a predetermined threshold, one of:
adjusting synchronization time for the third node, wherein the first node, the second node and the third node are connected via a second backhaul link the first node is a superior node for the second node, and the second node is a superior node for the third node; or
adjusting, by the second node, a transition nap between an uplink and a downlink based on the offset wherein the transition nap is configured by a donor node or by a superior node for the second node.
3. An electronic device for wireless communication, comprising processing circuitry configured to:
determine, based on a time offset between signals of different nodes connected via a backhaul link, an adjustment of synchronization time for at least one node of the different nodes,
wherein the adjustment is determined in the following manner:
transmitting, by a first node, timing configuration to a second node connected with the first node via a backhaul link;
transmitting, by the second node, a synchronization maintenance signal to the first node based on the timing configuration;
determining, by the first node, an adjustment of synchronization time for the first node or the second node based on the timing configuration and a timing for the synchronization maintenance signal.
