Abstract: Methods, systems, and devices for wireless communications are described. The methods, systems, and devices may enable a base station to transmit a measurement configuration for measuring interference (e.g., cross link interference (CLI)). The measurement configuration may include a measurement direction configuration for measuring the interference. Additionally or alternatively, the UE may select a measurement direction configuration for measuring interference based on the measurement configuration. The UE may measure interference based on the measurement configuration. The UE may transmit a measurement report to the base station. The measurement report may include an indication of the selected measurement direction configuration.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for determining quasi co-location (QCL) and/or transmission configuration information (TCI) state assumption information for a dynamic control resource set (CORESET). In some cases, if certain conditions are met, a user equipment (UE) may follow QCL assumptions for a physical downlink shared channel (PDSCH) scheduled by a same PDCCH that indicated the dynamic CORESET. An example method by a UE generally includes receiving at least one downlink control information (DCI), of a first physical downlink control channel (PDCCH), that schedules at least one dynamic CORESET; and receiving a second PDCCH in the dynamic CORESET, wherein the UE is to apply at least one QCL assumption associated with a PDSCH for the at least one dynamic CORESET if one or more conditions are met.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor a unicast channel for a first downlink transmission from a base station using a first semi-persistent scheduling (SPS) configuration. The UE may receive downlink control information (DCI) from the base station indicating a second SPS configuration associated with a different coverage level than the first SPS configuration. In some cases, the DCI may be DCI that is common to a set of UEs. Here, the DCI may indicate the second SPS configuration and the UE may identify a set of parameters associated with the second SPS configuration based on a radio resource control (RRC) message received prior to the DCI. Based on receiving the indication of the second SPS configuration, the UE may monitor the unicast channel for a second downlink transmission from the base station using the second SPS configuration.

Abstract: Aspects are provided which improve LBT by associating contention windows with transmission burst lengths and by allowing contention windows and maximum burst lengths to be adjusted based on interference activity. For downlink, a UE receives a PG for a downlink transmission from a base station indicating a CCA length based on a contention window size associated at least with a burst length for the downlink transmission. The UE performs, after receiving the pre-grant, a CCA based on the CCA length, transmits an APG to the base station when the CCA is successful, and receives the downlink transmission in response to the APG. For uplink, the base station performs a CCA based on a contention window associated at least with a burst length for an uplink transmission, transmits an uplink grant to the UE when the CCA is successful, and receives the uplink transmission in response to the uplink grant.

Abstract: Apparatus, methods, and computer-readable media for facilitating phase jump estimation for SL DMRS bundling are disclosed herein. An example method includes receiving, from another device, first information at a first symbol of a first slot, the first slot including at least the first symbol and a first reference signal. The example method also includes receiving second information at a second symbol of a second slot, the second slot including at least the second symbol and a second reference signal, the first information and the second information being repetitions. The example method also includes generating a first reference signal copy based at least on the second reference signal and a phase jump between the first slot and the second slot. Additionally, the example method includes performing channel estimation across the first slot and the second slot based on an aggregation of the first reference signal and the first reference signal copy.

Abstract: Methods, systems, and devices for wireless communications are described. A device such as a user equipment (UE) or a base station may identify a beam switching capability of the UE, the beam switching capability indicating a threshold quantity of beam switches during a transmission time interval, a threshold quantity of symbol periods between beam switching operations, or a combination thereof. The device may determine that the beam switching capability of the UE is satisfied based at least in part on one or more parameters (e.g., one or more symbol period durations, one or more quantities of beam switches during a transmission time interval, one or more adjustment parameters, one or more threshold values associated with the capability of the UE, etc.). The device may perform one or more beam switching operations based on determining that the beam switching capability is satisfied.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, based at least in part on the UE being a reduced-capability UE, control information on a reduced capability control resource set (CORESET) at least partially in a reduced capability region of a CORESET region, wherein the reduced capability CORESET is associated with a reduced configuration relative to a CORESET for a non-reduced-capability UE; and communicate in accordance with the control information. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communication are described. Data may be received during transmission time intervals (TTIs) that have a short duration relative to other TTIs. The short-duration TTIs may occur within or overlap a longer duration TTI, such as a subframe. Feedback responsive to the data may be generated and assigned for transmission during an uplink TTI according to a feedback timing or delay, which may be selected to reduce latency or balance the payload size of uplink messages sent during the assigned uplink TTI. Data and feedback assignments in short-duration TTIs may be configured based on a time division duplexing (TDD) configuration for some TTIs (e.g., subframes). TTIs that are a Long Term Evolution (LTE) subframe, an LTE slot, and a duration of two LTE symbol periods may be supported. Portions of special TTIs may be used for transmissions according to shorter-duration TTIs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a source UE, a sidelink communication. The UE may generate a transmit power control command based at least in part on a measurement of the sidelink communication. The UE may transmit, via a sidelink feedback channel, the transmit power control command to control a transmit power, for another sidelink communication, of the source UE. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that provide for managing transmissions using multiple component carriers (CCs) in which transmissions using one or more of the CCs may span less than a full transmission time of a slot or other transmission time interval. A UE may signal a capability to transmit such transmissions, and one or more capabilities related to carrier aggregation that may be used by a base station for scheduling of transmissions on different CCs. In the event that overlapping transmissions on two or more CCs exceed a maximum power threshold, various techniques for dropping at least a portion of one or more transmissions of one or more CCs are described.
