Abstract: Techniques for implicitly configuring resources for radio link monitoring or beam failure detection. An example method generally includes identifying that RLM resources or BFD resources are configured implicitly by at least in part: obtaining TCI states, for PDDCH CORESETs, obtaining an indication that at least one of the TCI states is activated to become an active TCI state of the PDCCH CORESETs, identifying one or more CSI-RS resources configured in the at least one of active TCI states of the PDCCH CORESETs, and if the UE does not support RLM or BFD based on the CSI-RS or the one or more CSI-RS resources are AP or SP, determining a SS block for RLM or BFD that has a QCL relationship with the one or more CSI-RS resources of the at least one of active TCI states; and performing RLM or BFD based on the SS block.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may attempt to connect to a base station using a random access procedure. During the random access procedure, the base station may transmit control information and data associated with a random access response (RAR) during an RAR window. The UE may identify a channel quality and may transmit a random access request of a first type to the base station. The base station may receive the random access request and transmit repeating instances of the control information or the data, or both, based on identifying that the random access request is of the first type. The UE may use soft-combining to increase the likelihood of successfully decoding the control information and the data associated with the RAR, and likewise may increase the likelihood of successfully receiving the RAR from the base station.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may attempt to connect to a base station using a random access procedure. During the random access procedure, the base station may transmit control information associated with a random access response (RAR) during a RAR window. The UE may attempt to receive a single instance of the control information and, in some cases, may be unable to receive and decode the single instance of the control information. The base station may configure one or more RAR windows (or segment(s) thereof) to support transmitting repeating instances of the control information and/or RAR. The UE may identify a quantity of instances of the repeated control information and combine the instances. The UE may successfully decode the combined instances of control information and identify a location for receiving the RAR.

Abstract: The present disclosure relates to physical downlink control channel (PDCCH) monitoring. For example, a method of wireless communication includes determining, by a user equipment (UE), whether one or more conditions is satisfied. The method also include performing, by the UE, physical downlink control channel (PDCCH) monitoring associated with a first cell based on a determination that the one or more conditions is satisfied. Other aspects and features are also claimed and described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive carrier information identifying at least one of: an initial absolute frequency for a carrier, a tone boundary offset value for the carrier, a number of resource blocks included in the carrier, or a frequency offset from a reference frequency; and determine a resource allocation of the carrier based at least in part on the carrier information and a subcarrier spacing of the user equipment. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive system information from a base station indicating at least one configuration rule for power control parameter setting for random access. The UE may measure one or more reference signals and may estimate a path loss of wireless communications between the base station and the UE based on the measured reference signals. The UE may select one or more parameters from one or more sets of parameters indicated in the configuration rule. The UE may select a first transmit power for a preamble of a random access message and a second transmit power for a payload of the random access message, based on the estimated path loss and the configuration rule for power control parameters and power ramping procedures. The UE may transmit the random access message according to the selected first and second transmit powers.

Abstract: Techniques are described herein that allow a user equipment (UE) to configure a subcarrier spacing value while monitoring synchronization signals of neighboring cells. In some wireless communication systems, synchronization signals in given radio frequency spectrum band may be transmitted using one of a plurality of different subcarrier spacings. In some cases, a network entity, such as a base station, may transmit an indication to the UE that indicates the subcarrier spacing used by a cell to transmit a specific set of synchronization signals. In some cases, the UE may select a subcarrier spacing based on a database of subcarrier spacings stored locally by the UE. In some cases, the UE may select the subcarrier spacing based on a predetermined configuration.

Abstract: Methods, systems, and devices for wireless communications are described that relate to a two-step random access procedure. Generally, the described techniques allow different configurations for a first message of a random access procedure depending on a connected-state of the user equipment (UE) performing the random access procedure. A base station may transmit configuration information to the UE and the UE may use the configuration information to determine resources, coding, block size, or other factors for transmitting the first message based on the radio resource control (RRC) connected state of the UE. The UE may then monitor for a random access response from the base station based on the first message from the UE.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform a dual active link handover procedure from a source base station to a target base station. During the dual active link handover procedure, the UE may have connections to both of the base stations concurrently. In such cases, transmission opportunities for communicating with the base stations may conflict. To handle conflicting transmission opportunities, the UE may drop a monitoring occasion or a packet reception for a base station based on prioritization rules. In some cases, to mitigate packet losses, the base station may configure re-transmissions or slot aggregation to provide the UE with additional opportunities to receive a packet. Additionally or alternatively, the UE may transmit a notification message to a base station indicating dropped monitoring occasions or packets.
