Abstract: Certain aspects of the present disclosure provide techniques for downlink and/or uplink beam management for full-duplex communications. An example method generally includes receiving, from a wireless node, a RS resource configuration indicating interference RS resources associated with interference reference signal transmissions; monitoring interference RSs via the interference RS resources; for each of the interference RS resources, determining a reception beam based at least in part on the monitored more interference RSs corresponding to the interference RS resources; receiving control signaling, from the second wireless node, indicating QCL information, which also indicates to either refrain from using any monitored interference RS resource in determining spatial reception parameters or identify at least one monitored interference RS resource to use in determining the spatial reception parameters; and determining the spatial reception parameters in accordance with the control signaling.

Abstract: Aspects are provided which allow a user equipment (UE) to identify a low-bandwidth (low-BW) CORESET-0 and associated CSS based on reception bandwidth of the UE. The base station may configure different frequency and time-domain resources of the low-BW CORESET in order to optimize resource utilization of the low-BW CORESET-0, and the low-tier UE may identify these resources of CORESET-0 and CSS from the system configuration information received in a master information block (MIB). As a result, low tier UEs may operate in a same cell as legacy UEs without the need for the base station to transmit additional signaling to either legacy UEs or lower tier UEs for the UEs to receive their respective CORESET-0's and identify a physical downlink channel (PDCCH).

Abstract: Certain aspects of the present disclosure provide techniques for a low cost (LC) user equipment (UE) to signal to a base station (BS) capabilities to receive physical downlink control channels (PDCCHs) in wireless communications systems. In an exemplary method, a UE signals to a base station (BS) a plurality of parameters for physical downlink control channel (PDCCH) reception by the UE and receives a PDCCH according to the plurality of parameters.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may receive a first downlink determining, based at least in part on an uplink transmission schedule for a user equipment (UE), one or more communications that are to be transmitted as a cross link interference reference signal (CLI-RS) during a time window. The BS may transmit, to the UE, an instruction to transmit the one or more communications as the CLI-RS during the time window. Numerous other aspects are provided.

Abstract: Aspects described herein relate to determining a first timing advance for transmitting communications to a base station, and determining a second timing advance for transmitting a reference signal to a user equipment. The communications can be transmitted to the base station based on the first timing advance, and the reference signal can be transmitted to the user equipment based on the second timing advance.

Abstract: 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.

Abstract: Aspects of the present disclosure relate to wireless communication. In aspects, a base station may determine one or more signaling parameters to be used to transmit one or more reference signals that identify the base station in association with remote interference management, wherein the one or more signaling parameters include at least one of: multiple time periods in which the one or more reference signals are to be transmitted; one or more mini-bands, within one or more sub-bands, in which the one or more reference signals are to be transmitted; one or more scrambling codes, selected from a pool of scrambling codes, to be used to scramble the one or more reference signals; or a combination thereof. The base station may transmit the one or more reference signals using the one or more signaling parameters to identify the base station in association with remote interference management. Other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may detect interference, in a remote interference management (RIM) scenario, in a set of sub-bands of a plurality of sub-bands of a bandwidth portion. The base station may transmit, to identify the set of sub-bands in which interference is detected, a set of reference signals configured to indicate the set of sub-bands in which the interference is detected. Numerous other aspects are provided.
