Aspects of the present disclosure provide techniques for interference coordination between wireless nodes (e.g., nodes of an Integrated Access and Backhaul (IAB) network). The techniques generally include determining, by a first wireless node, resources for sending an indication of interference coordination to a second wireless node, and sending the indication to the second wireless node using the determined resources, as part of an interference coordination procedure.

Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for managing remote interference using a previously detected relationship between an aggressor base station and a victim base station. The described techniques provide for allocating reference signal sequences for various victim base stations to send to an aggressor base station. The victim base station may trigger the aggressor base station to perform reference signal monitoring based on the previously detected victim-aggressor relationship, and may transmit a reference signal carrying a unique identifier based on the triggering. The first base station may send a request that the second base station to transmit a reference signal for enabling the first base station to measure interference of a wireless channel, and performing interference mitigation techniques at the first base station, the second base station, or both, to mitigate the remote interference.

A system that incorporates aspects of the subject disclosure may perform operations including, for example, obtaining uplink information associated with a downlink path, wherein the uplink information includes operational parameters used by a plurality of communication devices for transmitting wireless signals on a plurality of uplink paths; performing, based on the uplink information, a plurality of measurements of the plurality of uplink paths; identifying a measurement from the plurality of measurements that is below a threshold, thereby indicating an affected uplink path of the plurality of uplink paths; initiating a first filtering of the affected uplink path, wherein the initiating is based on the identifying and wherein the first filtering is based upon one or more first filtering parameters; and receiving instructions comprising one or more updated filtering parameters, wherein the instructions are received by the system at a port of the system. Other embodiments are disclosed.

A user equipment (UE) receives, from a base station, a message including at least one reporting configuration and resource configuration for a number of channel state information-interference measurement (CSI-IM) resource patterns associated with a first radio access technology (RAT). Each of the configured CSI-IM resource patterns corresponds to a time and frequency location in a resource block of a neighbor cell associated with a second RAT. The UE transmits one or more CSI reports based on the reporting configuration(s) and the resource configuration(s).

A network node includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code are configured to, with the at least one processor, cause the network node to: obtain frequency domain arrangement information for a first cell of a neighbor network node; map a first set of resource blocks allocated to a first user equipment in the first cell to a second set of resource blocks in a second cell of the network node based on the frequency domain arrangement information, the second cell having a frequency domain arrangement different from a frequency domain arrangement for the first cell; allocate a third set of resource blocks to a second user equipment based on the second set of resource blocks; and transmit data to the second user equipment using the third set of resource blocks.

The present disclosure provides a method (100) at a first network node and a method (300) at a second network node. The method (100) at the first network node comprises performing (110) scheduling in a first frequency band and providing (120) information related to a result of the scheduling to the second network node. The method (300) at the second network node comprises obtaining (310) information related to a result of scheduling by the first network node in a first frequency band and determining (320), based at least on the information, a size of a guard band between the first frequency band and a second frequency band to be scheduled by the second network node.

A wireless device may support a plurality of channel state information (CSI) processes. The wireless device may send an indication of a number of supported CSI processes to a first base station. The first base station may send to the wireless device a handover command, instructing the wireless device to handover to a second base station. The handover command may comprise configuration parameters for CSI processes associated with the second base station. The configuration parameters may be based on the number of CSI processes supported by the wireless device.

Methods and apparatus in a fifth-generation wireless communications network, including an example method, in a wireless device, that includes determining a reporting quality threshold for a parameter related to channel state information (CSI); performing a measurement for each of a plurality of beams from a first predetermined set of beams for evaluation; evaluating the measurement for each of the plurality of beams against the reporting quality threshold; discontinuing the performing and evaluating of measurements in response to determining that the reporting quality threshold is met for one of the beams, such that one or more beams in the first predetermined set of beams are not measured and evaluated; and reporting, to the wireless communications network, CSI for the one of the beams.

This application provides a method for sending a measurement report. The method includes a terminal device receiving first configuration information and second configuration information, where the first configuration information indicates a measurement resource and the second configuration information indicates a slot format of a non-serving cell of the terminal. The method also includes the terminal device sending a measurement report to a network device, where a measurement quantity type of the measurement report is related to the slot format of the non-serving cell, and the measurement report corresponds to the measurement resource.

In one embodiment, a method includes receiving messages from a set of base stations, wherein each message from abase station of the set of base stations indicates that the base station is interfered. The method further includes grouping the set of base stations into a set of reference signal groups based on the messages, each reference signal group being mapped to a reference signal group identifier; and the method continues with sending a respectively mapped reference signal group identifier to each of the set of base stations. Embodiments of the invention also include methods to group base stations causing the interference.
