Abstract: Methods, systems, and devices for wireless communications are described. A base station may implement cross-carrier scheduling. A user equipment (UE) may identify a minimum scheduling delay and may receive a downlink grant on a first CC. The UE may further identify the slot in which a downlink data transmission corresponding to the downlink grant will be received, and may identify the slot such that the minimum scheduling delay is satisfied. The UE may the receive the downlink data transmission, as indicated in the downlink grant, in the identified slot. In some examples, the UE and the base station may alternate between a long minimum scheduling delay and a short minimum scheduling delay. In some examples, the UE and the base station may alternate between a cross-carrier mode, and a self-scheduling mode.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may observe control channel monitoring occasions (PMOs) corresponding to different beams configured by a base station. The UE may identify a PMO in a system information window to monitor for downlink control information scheduling a shared channel carrying a system information message. The UE may receive an indication of which synchronization signal/physical broadcast channel (SS/PBCH) blocks are actually transmitted by the base station and determine corresponding PMOs within the system information window. The UE may then monitor for the downlink control channel within the system information window during the corresponding PMOs. The base station and the UE may also implement techniques for system information message repetition within a system information window.

Abstract: Various aspects described herein relate to techniques for mobility mode selection in uplink-based and downlink-based mobility in wireless communications systems. In an aspect, a method for wireless communications may include determining that a user equipment (UE) is operating in a first mobility mode, determining whether the UE satisfies at least one condition associated with mobility of the UE for mobility mode selection, and selecting a second mobility mode based on a determination that the UE satisfies the at least one condition, wherein each of the first mobility mode and the second mobility mode is an uplink mobility mode or a downlink mobility mode. The techniques described herein may apply to different communications technologies, including the 5th Generation (5G) New Radio (NR) communications technology.

Abstract: Methods, systems, and devices for wireless communications are described that support slot format determination for extended cyclic prefix (ECP) transmissions using normal cyclic prefix (NCP) slot formats. A slot format indicator (SFI) for NCP slots may identify transmission directions (e.g., uplink symbols, downlink symbols, or flexible symbols) for different symbols within a slot, and the SFI may provide an indication of a particular slot format that is to be used. Starting and ending times of each NCP symbol in a slot may be time domain mapped to starting and ending times of each ECP symbol in the slot. A transmission direction of each ECP symbol may be determined based at least in part on the transmission direction of at least a portion of at least one NCP symbol that fully or partially overlaps in the time domain with a corresponding ECP symbol.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a downlink message that includes a control channel monitoring periodicity and control channel offset for a radio frame. A user equipment (UE) may identify a set of slots within a radio frame to monitor for downlink control information (DCI) based on the received downlink message. The UE may identify a control channel candidate within a search space of each slot of the set of slots, and may identify the control channel candidate of a first slot based on calculations that include a current slot and a previous slot. There may be one or more slots that occur between the previous slot and the current slot. The UE may receive DCI that is user-specific based on the identified control channel candidate.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a reference signal preemption scheme associated with one or more reference signal resources being preempted for priority transmissions during a time period. The UE may determine that resources of one or more reference signals have been preempted during the time period and in accordance with the reference signal preemption scheme. The UE may implement a reference signal preemption response scheme that is selected based at least in part on the resources of the one or more reference signals being preempted.

Abstract: Methods, systems, and devices for wireless communications are described. A method may include receiving, from a base station and while being outside of a radio resource control (RRC) connected state, an indication of a length of downlink symbols used to transmit a physical downlink shared channel (PDSCH) that carries broadcast information, and decoding the PDSCH based on the indication. Another method may include receiving, from a base station, a PDSCH that carries broadcast information over a plurality of downlink symbols and while being outside of an RRC connected state, perform a first blind decoding of the PDSCH over a first set of the plurality of downlink symbols, and perform a second blind decoding of the PDSCH during a second set of the plurality of downlink symbols, the second set being different in length than the first set.

Abstract: Methods, systems, and devices for wireless communications are described for configuration aspects of a tracking reference signal in New Radio. A base station may select a first burst duration and a second burst duration for a tracking reference signal (TRS) burst, the first burst duration being different from the second burst duration, and may transmit configuration information indicating the first burst duration and the second burst duration to a user equipment (UE). The base station may transmit a first TRS burst having the first burst duration and a second TRS burst having the second burst duration. The UE may detect the first TRS burst having the first burst duration and the second TRS burst having the second burst duration based at least in part on the configuration information, and perform resource tracking based at least in part on the detected first TRS burst and the second TRS burst.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may identify a default monitoring periodicity for monitoring a control channel for a slot format indicator (SFI). For example, the default monitoring periodicity may be based on semi-static control signaling received from a base station or another suitable network entity. The wireless device may subsequently receive an indication of a dynamic monitoring periodicity for monitoring the control channel for the SFI. In some cases, the dynamic monitoring periodicity indication may be included in the SFI. The wireless device may then monitor the control channel for the SFI based at least in part on the dynamic monitoring periodicity.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit or otherwise indicate a semi-static slot format configuration and a dynamic slot format configuration to a user equipment (UE). The UE may determine a slot format configuration based on the received semi-static and dynamic slot format configurations. In some cases, the UE may replace certain resources of the semi-static slot format configuration with resources from the dynamic slot format configuration depending on a certain embodiment. Additionally or alternatively, the base station may transmit an anchor slot configuration to the UE, which may indicate which resources of the semi-static slot format configuration can be overridden or replaced by the dynamic slot format configuration.
