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: Methods, systems, and devices for wireless communications are described for a two-step random access channel (RACH) procedure in which uplink random access preamble and message transmission occasions may span multiple transmission slots. Reference signal resources for transmitting a reference signal with a first random access message of the two-step RACH procedure may include at least one symbol in each of the multiple transmission slots. The reference signal resources, reference signal sequence, or both, may be identified based on a particular uplink random access message transmission occasion, random access preamble transmission occasion, random access preamble sequence configuration, or any combinations thereof.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine a mapping between synchronization signal blocks (SSBs) and a random access message of a two-step random access procedure based on an indication in system information signaling or radio resource control (RRC) signaling. The random access message may include a random access preamble and a random access payload. The UE may determine, based on the mapping, an association between one or more beams carrying the SSBs and one or more additional beams carrying the random access preamble and the random access payload of the random access message. As a result, the UE may perform the two-step random access procedure with a base station according to the beam association, and coexist with a four-step random access procedure in a more reliable and efficient manner.

Abstract: Methods, systems, and devices for wireless communications are described. Devices of a wireless communications system may be configured to group data packets as a batch or file. In some cases, resources may be determined based on one or more resource grants corresponding to file communication. Other aspects may include DCI configurations corresponding to file communication, resource grants may be configured to assign resources for communication of a file. For example, a DCI may be specifically configured for granting resources for communication of a file. In another example, configured grants may include a configured grant index corresponding to communication of a file. Other aspects may include configuration of a UE for responding to a preemption indication when a file is scheduled for communication, power adjustments for communication of a file, reference signal configurations for communication of a file, and/or coherent detection/transmission across two or more packets of a file.

Abstract: Methods and apparatus for assisted frequency scan signaling are described. A method for wireless communication at a cell may comprise entering a semi-active state corresponding to an energy-saving mode of operation of the cell; configuring a downlink signal to assist at least one user equipment (UE) to detect a synchronization signal transmitted from at least one cell in an active state; and transmitting the downlink signal during the semi-active state. A method for wireless communication at a UE may comprise receiving a downlink signal from a cell in a semi-active state corresponding to an energy-saving mode of operation of the cell; detecting, based at least in part on the downlink signal, a synchronization signal transmitted from at least one cell in an active state; and establishing a connection with the at least one cell in the active state based at least in part on the synchronization signal.

Abstract: The described techniques relate to improved methods, systems, devices, and apparatuses that support interference mitigation for remote devices. A first wireless device (e.g., a base station) may detect remote interference with its communications caused by a second wireless device (e. g., a second, remote base station) based on, for example, a measured interference over thermal noise level exceeding a threshold. The first wireless device may identify a set of time-frequency resources for remote interference reference signals and a data transmission for a user equipment (UE) that is in communication with the first wireless device. The first wireless device may transmit a remote interference signal to a second wireless device (e. g., a second base station) via the set of time-frequency resources. The first wireless device may further signal a resource allocation to the UE for the UE to use for transmitting uplink transmissions to the first wireless device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless node may transmit configuration information indicating a first precoding matrix indicator (PMI) parameter and a second PMI parameter, wherein the first PMI parameter is associated with non-simultaneous activity of a distributed unit (DU) and a mobile termination (MT), and wherein the second PMI parameter is associated with simultaneous activity of the DU and the MT. The wireless node may perform a communication in accordance with a selected PMI parameter of the first PMI parameter and the second PMI parameter based at least in part on whether the DU and the MT are simultaneously active. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may be configured to monitor a set of beams, and may request an update to a monitoring configuration based on a position of the UE, an orientation of the UE, a rate of change of the position or orientation, or any combinations thereof. In some cases, the position or orientation information of the UE may include information for a current time period, predictive information for one or more future time periods, other information, or any combinations thereof. The UE may transmit a beam monitoring request to a base station for an updated monitoring configuration, such as a subset of a set of configured beams or an identified scan angle to be monitored by the UE.
