Abstract: Methods, systems, and devices for wireless communications are described to enable a user equipment (UE) to bundle reference signals, such as demodulation reference signals (DMRSs), by maintaining one or more coherence properties across DMRSs. A base station may transmit an indication of a DMRS bundling configuration to the UE, and the UE may transmit a DMRS bundling capability indication to the base station. The base station may transmit DCI to the UE, and the UE may determine whether to maintain or alter DMRS bundling (for example, maintain or alter one or more coherence properties) for one or more physical shared channels based on the DCI. The UE may maintain or alter one or more coherence properties of the one or more physical shared channels based on determining whether to maintain DMRS bundling and may transmit the one or more physical shared channels and associated DMRSs to the base station.

Abstract: A user equipment (UE) may be configured to receive configuration information from a base station, and the configuration information may indicate at least two different random access channel (RACH) request configuration parameters that each is associated with a respective radio resource control (RRC) state. The UE may be further configured to generate a first message associated with a two-step RACH procedure including a preamble and a payload, the payload including data on an uplink data channel and at least one reference signal. The UE may be further configured to transmit the first message to the base station using at least one of the at least two different RACH request configuration parameters that corresponds to an RRC state of the UE. The preamble may be transmitted on a first set of resources associated with a RACH occasion, and the payload may be transmitted on a second set of resources.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may identify a beam correspondence between a set of synchronization signals transmitted by a base station and an uplink positioning reference signal. The UE may receive a synchronization signal from a base station and determine a transmit beam for the UE to use to transmit the uplink positioning reference signal based on the received synchronization signal and the identified beam correspondence. The UE may then transmit the uplink positioning reference signal using the determined transmit beam. A base station may identify a beam correspondence between a set of synchronization signals and an uplink positioning reference signal, and transmit an indication of the beam correspondence. The base station may then receive the uplink positioning reference signal from a UE based on the transmitted indication of the beam correspondence.

Abstract: Methods, systems, and devices for wireless communications are described that provide for configuration of channel bandwidth that may be specific to a particular user equipment (UE). A UE may be configured with a channel bandwidth that is less than or equal to a channel bandwidth of the serving base station, and may also be different than a channel bandwidth of one or more other UEs that are served by the base station. The base station may signal the UE-specific channel bandwidth in UE-specific signaling, such as UE-specific radio resource control (RRC) signaling.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to monitor, via a receive beam, a first transmission time interval (TTI) of a plurality of different TTIs for a control resource set. The UE may decode the control resource set to obtain a first grant and a second grant. Upon decoding the control resource set, the UE may determine that the first grant and the second grant are associated with different parameters. In some cases, the parameters may be spatial quasi-colocation (QCL) assumptions mapped to the control resource set. The UE may decode, resources of a shared data channel indicated in at least one of the first grant and the second grant. In some cases, the UE may decode the resources during at least one of the first TTI and a second TTI of the plurality different TTIs.

Abstract: Methods, systems, and devices for wireless communications are described. In one example, a method includes selecting between a first frequency range and a second frequency range to transmit a physical channel, the second frequency range being higher than the first frequency range, and jointly encoding at least two fields of the physical channel based at least in part on the selected frequency range. In some cases, the method includes selecting between a first frequency range and a second frequency range to transmit a physical channel. In some cases, the second frequency range is higher than the first frequency range. The method may further include adjusting a quantity of bits associated with a field of the physical channel based at least in part on the selected frequency range.

Abstract: Methods, systems, and devices for wireless communications are described for dynamically configuring a schedule and a set of transmission resources for delivering additional system information. A first type of system information, such as remaining minimum system information (RMSI), may include configuration information indicative of the dynamically-configured schedule and set of transmission resources for delivering the additional system information, such as other system information (OSI). The dynamically-configured set of transmission resources for delivering the additional system information may be a control resource set (CORESET), and control information within the CORESET may be encoded with a radio network temporary identifier that is the same as or different than the first set of system information.

Abstract: Methods, systems, and devices for synchronization signal (SS) block and control resource set (coreset) multiplexing are described. Generally, the described techniques allow a base station to indicate, to a user equipment (UE), the location of a coreset including control information that may be used by the UE. Specifically, a base station may transmit an indication of a coreset configuration and an indication of a type of multiplexing used to multiplex the coreset with an SS block in the SS block to a UE. Accordingly, the UE may receive the SS block, and the UE may determine the location of the coreset based on the coreset configuration and the indication of the type of multiplexing used to multiplex the coreset with the SS block. The UE may then process the control information included in the coreset to identify the location of a data channel including additional system information.

Abstract: Techniques are described herein that allow a user equipment (UE) to configure a subcarrier spacing value while monitoring synchronization signals of neighboring cells. In some wireless communication systems, synchronization signals in given radio frequency spectrum band may be transmitted using one of a plurality of different subcarrier spacings. In some cases, a network entity, such as a base station, may transmit an indication to the UE that indicates the subcarrier spacing used by a cell to transmit a specific set of synchronization signals. In some cases, the UE may select a subcarrier spacing based on a database of subcarrier spacings stored locally by the UE. In some cases, the UE may select the subcarrier spacing based on a predetermined configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a message indicating that the UE is to execute a make-before-break handover procedure. The UE may transmit, during the make-before-break handover procedure and based at least in part on a prioritization rule, a first uplink communication to a target base station. The prioritization rule may indicate a relative priority for different uplink communications included in a group of uplink communications. The group of uplink communications may include at least the first uplink communication to be transmitted by the UE to the target base station and a second uplink communication to be transmitted by the UE to a source base station during the make-before-break handover procedure. Numerous other aspects are described.
