Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive information identifying one or more antenna switching capabilities and one or more carrier switching capabilities for a user equipment (UE), wherein the UE is associated with a baseline carrier combination; and determine an antenna switching capability for a target carrier combination based at least in part on the one or more antenna switching capabilities or the one or more carrier switching capabilities, wherein the target carrier combination is different than the baseline carrier combination. Numerous other aspects are provided.

Abstract: A base station may calculate a scheduling value based on at least one of a number of groups associated with a set of UEs operating on a cell provided by the base station a radio frame number, or a subframe number. The base station may send, based on the calculated scheduling value, at least one NRS in at least one PO on a narrowband control channel. A UE may receive, from the base station providing the cell, information associated with at least one PO for the UE. The UE may determine, based on the received information, scheduling information associated with at least one NRS in the at least one PO. The UE may detect the at least one NRS in the at least one PO on a narrowband control channel when the determined scheduling information indicates the at least one NRS is in the at least one PO.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for reporting aperiodic channel quality indicator (A-CQI) in a new Secondary Cell (SCell) state of Long Term Evolution (LTE) carrier aggregation. A User Equipment (UE) receives a request for reporting A-CQI relating to a Scell configured for the UE when the UE is in a first state corresponding to the Scell, the first state designed for a reduced SCell activation latency and to result in the UE using lower power as compared to when the UE is in a second state. The UE, in response to the request, reports the A-CQI for the Scell in accordance with a first A-CQI reporting configuration for the first state which is different from a second A-CQI reporting configuration for the second state.

Abstract: Methods, systems, and devices for wireless communications are described. A network may be configured to provide a beam measurement configuration to a UE that indicates durations for monitoring transmission beams, and tuning a component of the UE between the monitoring. The durations may include a first portion that a UE may use for a tuning operation and a second portion that the UE may use to monitor for or measure a respective reference signal. In various examples, the indicated durations may include a third portion that the UE may use for another tuning operation, or the durations may overlap with one another during an overlap duration that the UE may use for another tuning operation. During the indicated durations, the network may refrain from transmitting other downlink data or control information for the UE, and the UE may refrain from monitoring for such other downlink data or control information.

Abstract: Methods, systems, and devices for wireless communications are described in which repetitions of communications may be configured for multi-transport block (TB) communications. A UE may determine that an acknowledgment of one or more initial repetitions of one or more TBs is received, and may cancel one or more subsequent repetitions of the acknowledged TB(s). The acknowledgment of the one or more initial repetitions may be provided by a base station in a new resource grant that provides an implicit acknowledgment of one or more TBs. In cases where multiple different TBs may be associated with the prior resource grant, the UE can determine to drop one or more repetitions after an implicit acknowledgment of a TB based on whether the resource grants are for a single TB or are for multiple TBs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a multicast service available for subscription by the UE or to which the UE is already subscribed. The UE may transmit a message, to a network node, that may include UE assistance information (UAI) indicating at least one of a UE capability to process multicast transmissions or a feedback scheme preference for reporting feedback for the multicast transmissions. The UAI may also include at least one of a multicast carrier preference, band or carrier measurement report, a multicast priority indication, or a measurement and reporting scheme preference for the multicast transmissions. The network node may receive the UAI and determine one or more parameters for multicast communications with the UE based on the UAI. The UE may receive the multicast transmissions from the network node in accordance with the UAI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a set of system information blocks (SIBs) common to a set of cells of a non-terrestrial network (NTN), the set of SIBs indicating one or more parameters common to the set of cells for communications with the set of cells. The UE may receive a first SIB associated with a first cell of the set of cells of the NTN, where the first SIB includes cell-specific information indicating a first set of cell-specific parameters for communications with the first cell. The UE may then communicate with the first cell using the first set of cell-specific parameters associated with the cell-specific information of the first cell and at least a first sub-set of parameters of the one or more parameters that are common to the set of cells.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit buffer status information using configured periodic uplink resources. For example, a base station may configure dedicated periodic uplink resources, periodic random access resources, or periodic uplink grants to enable the UE to transmit the buffer status information. In some cases, the periodic random access resources may enable the UE to transmit a first message of a four-step or two-step random access procedure to indicate the buffer status information. Additionally or alternatively, the base station may configure a type of scheduling request for the UE to transmit that can indicate whether a buffer size falls within a range, where the base station then can more accurately allocate uplink resources in an uplink grant for the UE to transmit the uplink data based on receiving this type of scheduling request.

Abstract: In an example, a method of wireless communication of a base station may include assigning, by the base station, one or more resources to a group comprising a plurality of UEs that includes a first UE. The method may include receiving, by the base station from the first UE, a message on the one or more assigned resources. The message may include a cyclic redundancy check (CRC) scrambled with a group identifier for the group comprising the plurality of UEs. The message may include an indication of a UE identifier for the first UE within the group. The message may include a DMRS, where the indication of the UE identifier is represented by a sequence of the DMRS.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station may signal one or more emission limits for one or more different frequency bands, and two or more values for one of the emission limits may be provided. A first subset of user equipments (UEs) may be capable of aerial operations (e.g., unmanned aerial vehicles (UAVs) or drones) and may use a first value of the first emission limit and the second subset of UEs may not capable of aerial operations and may use a second value of the first emission limit. A UE status such as altitude or position, or transmission directivity may also be used to determine if the UE is to apply the first value or the second value for an emission limit of a frequency band.
