Abstract: Aspects of the disclosure relate to configuring, restricting, and/or setting bandwidth part (BWP) or frequency locations for switching from source to target cells in a Layer 1 (L1)/Layer 2 (L2)-Centric Inter-Cell Mobility communication systems. Switching may be allowed for either same, overlapping, or non-overlapping BWPs within an intra-frequency bandwidth shared by the source and target cells.

Abstract: Apparatus, methods, and computer readable media for facilitating of measuring occasions for transmissions based on frequency division multiplexing and spatial division multiplexing are disclosed herein. An example method for wireless communication at a UE includes receiving, from a base station, a hopping pattern indication configuring a hopping pattern. The example method also includes measuring interference of respective CSI-RS transmitted to other UEs included in a UE group based on at least the hopping pattern indication. The example method also includes reporting the measured interference to the base station. An example method for wireless communication at a base station includes transmitting a hopping pattern indication to each of a plurality of UEs. The example method also includes transmitting reference signals for the plurality of UEs using the hopping pattern among multiple subbands, and receiving a report of interference measured by each of the plurality of UEs based on the reference signals.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish a first connection with a source base station. The UE may determine that a handover procedure is being performed for establishing a second connection with a target base station. The UE may monitor, during a monitoring period instantiated at a physical layer of a protocol stack of the UE, for a control signal acknowledging success of the handover procedure from a target base station. The UE may transmit, based at least in part on a result of the monitoring during the monitoring period, a physical layer signal or a medium access control layer signal to the source base station indicating that the handover procedure was unsuccessful based at least in part on a failure to successfully receive and decode the control signal.

Abstract: Methods, systems, and devices for wireless communications are described. In some examples, a random access occasion may overlap in time with a synchronization signal block resource, where the random access occasion and the synchronization signal block resource have a same index. In some such examples, a base station may transmit, to a user equipment (UE), an indicator of a mapping of the random access occasion to an uplink beam that is associated with a synchronization signal block resource with a different index than the random access occasion. The UE may transmit, to the base station, a random access preamble over the random access occasion using the uplink beam.

Abstract: Aspects are provided which allow a base station to dynamically select or indicate an active CORESET associated with a search space or set of PDCCH candidates. The base station selects, for at least one UE, an active CORESET associated with a search space for a period of time. The base station transmits a dynamic indication of the active CORESET associated with the search space to the at least one UE. A UE receives the dynamic indication of the active CORESET associated with the search space for the period of time. The UE then monitors for a downlink control channel during the period of time based on the dynamic indication of the active CORESET.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) may receive, from a base station, a configuration indicating a channel quality threshold that the UE may use to identify an interference-based beam failure indicator type. The UE may receive a reference signal for performing one or more signal measurements in accordance with the configuration. Based on the one or more signal measurements and the channel quality threshold, the UE may report an indication of the type of beam failure indicator to the base station.

Abstract: Aspects of the present disclosure include methods, apparatuses, and computer readable media for receiving a reactivation downlink control information (DCI) associated with a new periodic resource configuration and an updated uplink feedback parameter for a scheduled uplink control information transmission, receiving downlink control information, changing a transmission parameter of the scheduled uplink control information transmission based on the updated uplink feedback parameter, and transmitting the scheduled uplink control information transmission based on the changed transmission parameter to indicate uplink feedback regarding reception of the reactivation DCI.

Abstract: Methods, systems, and devices for wireless communications are described. The techniques described herein support dynamically indicating uplink control channel repetition multiple different types of uplink signaling. A user equipment (UE) may receive first control signaling indicating a first repetition factor for transmission of a feedback message associated with a beam or transmission configuration indicator (TCI) state. The UE may receive second control signaling scheduling transmission of a control message associated with the beam or TCI state. The UE may transmit, in accordance with a second repetition factor, the control message based at least in part on both the feedback message and the control message being associated with the beam. In some cases, the second repetition factor may be configured with the second control signaling.

Abstract: Methods, systems, and devices for wireless communications are described. A device in a wireless network may identify a resource for wireless communication, the resource being in a first state where the resource is active for wireless communication and is inactive for a communication failure recovery procedure. The device may determine that a communication failure has occurred during a first communication period. The device may transition, during a second communication period and based at least in part on the communication failure, the resource to a second state where the resource is inactive for wireless communication and is active for the communication failure recovery procedure. The device may perform the communication failure recovery procedure using the resource transitioned to the second state.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may select a random access channel (RACH) occasion (RO) based on one or more channel quality thresholds, such as reference signal received power (RSRP) thresholds. A base station may determine a set of RO types for receiving RACH transmissions. The base station may determine a channel quality threshold for each RO type. The base station may broadcast a configuration indicating the RO types and the associated channel quality thresholds. The UE may receive the configuration and measure a channel quality between the UE and the base station. Based on the measured channel quality, the UE may determine which RO types are available based on the indicated channel quality thresholds, and select an RO for transmitting a RACH preamble to establish a connection with the base station based on the available RO types.
