Abstract: Methods, systems, and devices for wireless communications are described. Described techniques provide for dynamic configuration of feedback, repetition, and/or modulation and coding scheme(s) for transmissions within an application data unit (ADU). A user equipment (UE) and a network entity may communicate control signaling indicating transmission configurations for a set of multiple time domain durations within an ADU and a start of a first time domain duration. The transmission configurations may indicate a number of repetitions for each transmission. In some cases, the network entity may transmit control signaling that separately configures a number of repetitions for each feedback process of a set of multiple feedback processes associated with an ADU and indicates whether repetition is enabled for each feedback process and a redundancy version identifier sequence for repetitions for each feedback process. The UE and the network entity may communicate transmissions within the ADU in accordance with the control signaling.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish a connection, with base station, over a first and second component carrier and may monitor a search space configured for scheduling multiple component carriers. In some cases, the UE may be configured to monitor a search space allocated for a virtual component carrier associated with scheduling multiple component carriers, or the UE may be configured to monitor for a subset of physical downlink control channel (PDCCH) candidates in search spaces associated with the first and second component carriers, where the subset of PDCCH candidates may be allocated for multi-component carrier scheduling. The UE may receive downlink control information (DCI) that schedules a set of data transmissions over the first and second component carriers and the UE may perform or receive the set of data transmissions over the first and second component carrier.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive from a network entity a message indicating one or more sets of parameters for a set of carriers supported by the UE, the one or more sets of parameters indicating communication parameters for communications via the set of carriers. The UE may monitor for a field of a control message based on the message. A field size of the field may be based on the sets of parameters, and a respective value for the field may indicate a respective set of parameters of the sets of parameters for one or more carriers of the set of carriers. Based on receiving a control message and decoding the associated field, the UE may communicate via at least one carrier of the set of carriers using the respective set of parameters for the at least one carrier.

Abstract: Methods, systems, and devices for wireless communication are described. A network entity may schedule uplink resource allocations across multiple cells by defining selection criteria for the uplink resource allocations in which to transmit a channel state information (CSI) report. For example, a user equipment (UE) may receive a control signal from the network entity, which may schedule the UE to transmit the CSI report in an uplink resource allocation on a component carrier in a carrier aggregation configuration. In some examples, the UE may transmit the CSI report by multiplexing the CSI report in uplink resource allocations on multiple component carriers. In some examples, the CSI report may be transmitted in an uplink resource allocation on a smallest component carrier index. Accordingly, the defined selection criteria may allow for more efficient procedures at the UE, which may result in increased efficiency and decreased overhead.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a control resource set (CORESET) associated with a first radio access technology (RAT). The UE may receive an indication of a pattern for puncturing a control signal associated with the first RAT around resources allocated for reference signals associated with a second RAT. The UE may communicate the control signal according to the pattern. In some examples, the CORESET may be associated with a transmission configuration indicator (TCI) state and the UE may receive a message scheduling a data signal based on the CORESET. The data signal may be associated with the first RAT. The UE may receive an indication of a pattern for rate-matching the data signal around the resources allocated for reference signals associated with the second RAT. The UE may communicate the data signal according to the pattern.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a carrier aggregation (CA) configuration for communications on a set of cells. The UE may determine that signals transmitted on the set of cells may be spatially quasi co-located based on the CA configuration and a predetermined relationship rule. For example, the UE may determine that the signals are spatially co-located based on receiving multiple synchronization signal blocks (SSBs) that have a same SSB index, receiving a common SSB, assuming that an SSB and reference signals sourced by the SSB are spatially quasi co-located, receiving a signal from a particular cell of the set of cells, or receiving a common spatial QCL relationship during a configured period of time. Once the spatial QCL relationship is determined, the UE may receive the signals transmitted on the set of cells based on the spatial QCL relationship.

Abstract: Certain aspects of the present disclosure provide techniques for carrier group based multiple-input multiple-output (MIMO) layers and antenna adaptation. A method that may be performed by a user equipment (UE) includes receiving a configuration of one or more groups of component carriers (CCs) and, for each group of CCs, one or more sets of configured maximum number of MIMO layers. Each set includes a configured maximum number of MIMO layers associated with each CC in the group. The UE receives an indication of at least one of the one or more sets and determines the configured maximum number of MIMO layers associated with each CC in the corresponding group of CCs based on the indication.

Abstract: This disclosure provides systems, methods and apparatus for communicating a satellite behavior change. In one aspect, a satellite identifies a satellite behavior change to occur for the satellite of a non-terrestrial network for cellular communications. The apparatus also signals the satellite behavior change to a user equipment serviced by the satellite. In another aspect, a user equipment obtains, from a satellite servicing the user equipment, a signaling of a satellite behavior change to occur for the satellite. The user equipment also adjusts one or more user equipment parameters for cellular communication based on the obtained signaling. The satellite behavior change may include a satellite attitude or a transmit power or coverage area of one or more satellite beams. The user equipment parameters may include satellite or beam selection or reselection to listen to paging information, satellite or beam handover parameters, or transmit power control parameters.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may provide hybrid automatic repeat request (HARQ) feedback for multiple physical channels (e.g., multiple physical downlink shared channels (PDSCH)) scheduled via cross component carrier scheduling. A base station may transmit downlink control information (DCI) messages via physical downlink control channel (PDCCH), to the UE to schedule the multiple PDSCH over multiple component carriers. The UE may monitor for the multiple PDSCH over the multiple component carriers, respectively. The UE may identify resource allocations to use for HARQ feedback transmissions associated with the multiple PDSCH, based on the DCI messages received. The DCI may include a number of control fields that the UE may use to determine resource allocations to use for the HARQ feedback transmissions. The UE may thus improve coverage for wireless communications by supporting HARQ feedback for multiple PDSCH scheduled via cross component carrier.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support reduced bandwidth devices and particularly, allocation of more than three orthogonal frequency division multiplexing (OFDM) symbols in the time domain to a control resource set (CORESET). In a first aspect, a method for wireless communication includes receiving, from a base station at a user equipment (UE), a first message that indicates a CORESET configuration. The CORESET configuration allocates more than three OFDM symbols in the time domain to a CORESET. The method further includes monitoring a set of time and frequency resources to receive a second message from the base station at the UE. The set of time and frequency resources have the CORESET configuration. Other aspects and features are also claimed and described.
