Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit a configuration indicating a transmission configuration indicator (TCI) state switching pattern and a TCI state switching period to a user equipment (UE). The UE may perform TCI state switching according to the TCI state switching pattern and period, and the UE may receive a downlink transmission according to the TCI state switching pattern. The UE may receive a downlink control information (DCI) including an indication of a TCI state for a subsequent TTI. The UE may receive the downlink signal in accordance with both the TCI state switching pattern and the indication in the DCI. The UE may receive a configuration message indicating a first DCI state, receive a DCI indicating a second TCI state for a subsequent TTI, switch to the second TCI state, and receive a downlink signal using the second TCI state.

Abstract: Methods, systems, and devices for wireless communications are described. A first base station may transmit a request for a user equipment (UE) to provide a physical layer report for a second base station. The second base station may be a base station of a dual connectivity configuration, a deactivated base station of the carrier aggregation configuration, or a non-serving base station of the UE. The UE may measure transmissions of the second base station and generate, at the physical layer of the UE, a physical layer report based on the measurements. The UE may transmit the physical layer report to the first base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a dropping rule relating to: a first triggering communication, of a first transmit receive point (TRP), that triggers a first timeline for a first subsequent communication of the first TRP, and a second triggering communication, of a second TRP, that triggers a second timeline for a second subsequent communication of the second TRP, wherein the dropping rule indicates one or more communications to be dropped when the first triggering communication starts after a start of the second triggering communication and the first subsequent communication starts before a start of the second subsequent communication; and drop the one or more communications based at least in part on the dropping rule. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control information indicating a resource allocation pattern for a downlink transmission that is configured for transmission using a plurality of beams and a plurality of mini-slots, where a duration of a mini-slot is less than a duration of a slot. The UE may identify a start time of a first mini-slot of the plurality of mini-slots and a length of the first mini-slot based on the resource allocation pattern, and receive the downlink transmission based on the start time of the first mini-slot and the length of the first mini-slot.

Abstract: Certain aspects of the present disclosure provide techniques for transmitting simultaneous multi-beams on the same wireless resource. One example method includes determining a set of transmission (TX) beams for simultaneous transmissions to or from a user equipment (UE), signaling to the UE an indication of the TX beams, and transmitting simultaneously via the TX beams.

Abstract: Certain aspects of the present disclosure provide techniques for preconfiguring transmission configuration indication (TCI)-states at a user-equipment (UE) to reduce handover latency. Certain aspects provide a method for wireless communication. The method generally includes receiving, at a UE, a message indicating a first TCI-state for a current serving base station (BS) and a second TCI-state for a target BS, performing handover to the target BS, and activating the second TCI-state for the target BS after the handover.

Abstract: Aspects of the present disclosure provide various apparatuses and methods for extending a reference signal to facilitate carrier aggregation (CA). In some examples, a network includes a primary cell and one or more secondary cells that use a millimeter wave (mmW) carrier. When a UE is beyond the range of a reference signal from the secondary cell, the primary cell may trigger the secondary cell to increase the range of its reference signal using a higher gain beam and/or reference signal repetition.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may transmit procedure-specific uplink power parameters to one or more user equipments (UEs) in a cell. A UE may determine a procedure including one or more uplink transmissions. The UE may determine a transmit power level corresponding to the procedure based at least in part on the procedure-specific uplink power parameters. The UE may transmit the one or more uplink transmissions using the determined transmit power level.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may identify time and frequency resources for a physical downlink shared channel (PDSCH) to be transmitted to a user equipment (UE) in a first transmission time interval (TTI). The base station may transmit configuration information for a control channel search space set in a second TTI. The second TTI may precede the first TTI. The configuration information may include an indication of an absence of a physical downlink control channel (PDCCH) transmission to send in the control channel search space set indicating the identified time and frequency resources for the PDSCH, and a set of time and frequency resources for the control channel search space set. The UE may receive the configuration information and identify the time and frequency resources allocated for the PDSCH in the second TTI, and receive the PDSCH transmission in the second TTI.

Abstract: A first apparatus may determine a first schedule associated with the one or more repetitions of the control information on the control channel based on the first information. The first apparatus may receive, from the network, at least one of the one or more repetitions of the control information on the control channel based on the first schedule, wherein the control information indicates a second schedule associated with a random access response (RAR) on a data channel. The first apparatus may receive, from the network, the RAR on the data channel based on the second schedule.
