Abstract: Aspects are provided allowing a first base station to distinguish between cross-link interference and remote interference caused to a second base station and to apply different mitigation mechanisms based on the type of interference. A UE receives from a second base station a reference signal based on a reference signal identifier that indicates a location of the second base station that is experiencing interference from the first base station. The UE sends to the first base station an indication of the reference signal received from the second base station. The first base station receives from the UE the indication of the reference signal from the second base station based on the reference signal identifier. The first base station applies a mitigation mechanism based on whether the reference signal identifier indicates that the second base station is a remote base station or a neighbor base station.

Abstract: Methods and apparatuses described herein provide a physical downlink control channel (PDCCH) candidate hopping function that reduces collisions between PDCCH candidates, particularly between PDCCH candidates associated with reduced capability user equipment (UE). For example, the hopping function may be implemented as part of a PDCCH candidate to control channel element (CCE) function or may be applied separately from the PDCCH candidate to CCE function. The hopping function may reduce persistent collisions between PDCCH candidates by correlating the mapping behavior with a value that changes over time. Some techniques and apparatuses described herein provide signaling for configuration and activation/deactivation/modification of the hopping pattern. Thus, collisions between PDCCH candidates are reduced, thereby conserving computing resources and wireless communication resources. Furthermore, the reduction of collisions may improve performance of UEs with reduced PDCCH capabilities, such as reduced-capability UEs. Numerous other aspects are provided.

Abstract: Aspects described herein relate to physical downlink control channel (PDCCH) limits for multiple cells scheduling one cell in fifth generation new radio (5G NR). In an example, the aspects may include determining a PDCCH limit corresponding to at least one of a number of blind detections (BDs) and a number of control channel elements (CCEs) used for decoding PDCCH candidates for a first cell that schedules a second cell, and at least a third cell that schedules the second cell, wherein the third cell is the same cell as the second cell or the third cell is different from the second cell; and receiving one or more PDCCH transmissions from the first cell and the third cell based on the PDCCH limit.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a span configuration conflict between two or more span configurations associated with a span pattern for a carrier, wherein the two or more span configurations are associated with respective per-span capabilities for at least one of a quantity of non-overlapped control channel elements (CCEs) or a quantity of blind decodes to be performed for the carrier; select a span configuration or a per-span capability from the two or more span configurations to be used for the span pattern; and receive a communication on the carrier in accordance with the selected span configuration or the selected per-span capability. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods and apparatuses for identifying physical downlink control channel (PDCCH) parameters, such as a PDCCH blind decode limit and a PDCCH control channel element limit, for implementations where a user equipment (UE) is configured with two or more cell groups. The techniques described herein permit the UE or a base station to determine the quantity of cell groups that is to be considered when determining the PDCCH parameters, permit the UE to indicate PDCCH capability values across multiple frequency ranges, and permit the base station to schedule a quantity of PDCCHs for the UE that results in a quantity of blind decodes that exceeds a PDCCH blind decode limit or a quantity of control channel elements that exceeds a PDCCH control channel element limit.

Abstract: The present disclosure relates to methods and devices for wireless communication of an apparatus, e.g., a UE and/or a base station. In one aspect, the apparatus may receive, from a base station, at least one SSB. The apparatus may also determine a RSRP of the at least one SSB. Additionally, the apparatus may transmit, to the base station if the RSRP of all of the at least one SSB is less than a threshold, an indication of a reduced UE capability of the UE during a RACH procedure. The apparatus may also transmit, to the base station if the RSRP of one of the at least one SSB is greater than or equal to the threshold, the indication of the reduced UE capability of the UE after entering into a RRC connected state upon completion of the RACH procedure.

Abstract: Disclosed are techniques for detecting a potential false base station (FBS). In an aspect, a user equipment (UE) or a location server obtains a first location estimate of the UE based on a cellular network-based positioning procedure involving one or more cells, obtains a second location estimate of the UE based on a non-cellular network-based positioning procedure, determines whether or not a difference between the first location estimate and the second location estimate is greater than a distance threshold, and performs a mitigation operation based on the difference being greater than the distance threshold.

Abstract: This disclosure provides systems, methods and apparatus including computer programs encoded on computer storage media, for a user equipment (UE) to determine and apply limits to physical downlink control channel (PDCCH) processing in a dual active protocol stack handover scenario. In one aspect, the UE utilizes a joint blind decode capability for both a source cell group and a target cell group to determine whether a total limit for PDCCH candidates to monitor or non-overlapped control channel elements (CCEs) to monitor is applicable. The UE may identify a per cell limit for each configured single transmit receive point (TRP) cell and each multiple TRP cell based on a sub-carrier spacing SCS of the cell and the determination. The UE may include an interface configured to obtain a PDCCH for a slot. The UE may perform blind decoding operations on CCEs up to the per cell monitoring limit for each cell.
