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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information indicating a master cell group (MCG) maximum power value and a secondary cell group (SCG) maximum power value. The UE may determine whether a combination of the maximum power values satisfies a threshold. The UE may perform a transmission on the SCG using a first transmit power and a transmission on the MCG using a second transmit power, wherein, based on the combination of the MCG maximum power value and the SCG maximum power value satisfying the threshold, the first transmit power is determined based on a time offset, or wherein, based on the combination of the MCG maximum power value and the SCG maximum power value failing to satisfy the threshold, the first transmit power is determined without using the time offset. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a deadline prior to a first uplink transmission associated with a secondary cell group (SCG), wherein the first uplink transmission is associated with a first priority level; determine whether to perform a second uplink transmission associated with a master cell group (MCG), wherein the second uplink transmission is initiated after the deadline, and wherein the second uplink transmission is associated with a second priority level; and adjust a transmit power of the first uplink transmission based at least in part on at least one of: determining whether to perform the second uplink transmission, or the first priority level and the second priority level. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure propose techniques for transmission time interval (TTI) bundling for physical downlink shared channel (PDSCH) in long term evolution (LTE). According to certain aspects a method is provided for wireless communications. The method may be performed, for example, by a user equipment (UE). The method generally includes identifying a transmit time interval (TTI) bundle comprising a subset of subframes from a set of subframes for transmitting data on a physical downlink shared channel (PDSCH) and receiving the data on the PDSCH in the subset of subframes.

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: 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.
