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. The user equipment (UE) may initiate a successive cancellation list (SCL) decoding procedure, and may perform the SCL decoding procedure across various nodes (e.g., for each information bit through a decoding tree). At each node, the UE may determine whether a relationship between a first path metric and a second path metric satisfy a threshold. In some examples, the UE may determine whether multiple thresholds are satisfied. If conditions are satisfied (e.g., the relationship between the two path metrics satisfies a threshold), then the UE may decrease a list size of the SCL decoding.

Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for downlink control information (DCI) communication and processing. One example method generally includes determining a limit, between a transmission time of a control channel carrying a DCI of a plurality of DCI and a time of an event enabled by the DCI, of a quantity of the plurality of DCI in a frame, generating a frame comprising the plurality of DCI in accordance with the determined limit, and transmitting the frame to a user-equipment (UE).

Abstract: Certain aspects of the present disclosure provide techniques for power savings for reduced capability devices. A method that may be performed by a user equipment (UE) includes receiving a shared bandwidth part (BWP) configuration and a group common BWP configuration. The group common BWP configuration indicates a group common BWP shared by a group of UEs, including the UE, having one or more common capabilities or a common UE type. The method includes communicating using the group common BWP based on the group common BWP configuration.

Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus maybe a base station or a user equipment (UE). In an aspect, the apparatus may determine locations for a number of Demodulation Reference Signal (DM-RS) symbols to be transmitted within a scheduling unit of a channel included in a slot or mini-slot based on a selection between a first set of predetermined DM-RS positions and a second set of predetermined DM-RS positions. The apparatus may transmit the number of DM-RS symbols in the scheduling unit based on the determined locations.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a first slot format configuration for a first cell associated with a first radio access technology (RAT) and a first radio frequency spectrum band that conflicts with a second slot format configuration for a second cell associated with a second RAT and a second radio frequency spectrum band during at least a portion of a transmission time interval (TTI). The UE may determine that the first cell has a priority over the second cell, based on the configured slot formats or based on the radio frequency bands, and may drop a communication on the second cell based on the identified priority. The UE may then communicate during at least a portion of the TTI on the first cell while the UE drops a communication on the second cell.
