Abstract: Methods, systems, and devices are described for wireless communications. A wireless communication device may switch between a distributed and a clustered transmission scheme for control information transmissions. In some cases, the base station may indicate to a UE that a clustered control information transmission scheme will be used and may also indicate a monitoring pattern informing the UE how to identify its own control information in a control information set. For instance, a base station may indicate to the UE that a preferred beam of the UE is correlated with a symbol position of the UE's control information in the control information set. In some cases, the base station may indicate to a UE that a distributed control information transmission scheme will be used.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a first hybrid automatic repeat request acknowledgement (HARQ-ACK) payload for a first component carrier (CC) set based at least in part on a first downlink assignment index (DAI). The UE may determine a second HARQ-ACK payload for a second CC set based at least in part on a second DAI. The UE may transmit the first HARQ-ACK payload for the first CC set and the second HARQ-ACK payload for the second CC set. Numerous other aspects are provided.

Abstract: User equipment (UE)-specific information may be transmitted within a control resource set configured to carry resources common to UEs within a system. The UE-specific information may be associated with a search space having an aggregation level different from aggregation levels used with the common control resources and may occupy different modulation symbols within the common control resource set (e.g., to support flexible scheduling for multiple UEs). A base station and UE may operate in a system using one or more control resource sets within a system bandwidth. The UE may detect common control resources by monitoring decoding candidates in the control resource set according to a first set of aggregation levels. The UE may detect UE-specific control resources by monitoring decoding candidates in the control resource set according to other aggregation levels. The UE and base station may communicate based on control information obtained from the monitoring.

Abstract: A method and apparatus for utilizing a dedicated reference signal for demodulating a Physical Broadcast Channel (PBCH) in a wireless communication system is disclosed. For example, the method and apparatus include configuring, at a network entity, at least one dedicated Demodulation Reference Signal (DMRS) in one or more symbols corresponding to a PBCH, each dedicated DMRS being used for demodulating the PBCH. The described aspects further include transmitting, by the network entity, the at least one dedicated DMRS to one or more UEs using at least a single antenna port.

Abstract: Split synchronization signal configuration for unified synchronization channels and techniques for indicating communication block boundaries in wireless communication systems that use a unified synchronization signal configuration that may be used in different communication modes are described. The disclosed split synchronization signal configuration allows the same synchronization signal configuration to be used in different communication modes (or numerologies) that operate on different frequencies. The boundary indication techniques of embodiments allow efficient indication of the beginning of a communication block (such as a frame, subframe, or slot) relative to the beginning of a unified synchronization signal configuration.

Abstract: Tracking reference signal designs for deployments without continuous reference signal transmission are described. The tracking reference signals may be extended in the frequency domain from a synchronization signal block and may occupy a subset or all of the symbol periods of the synchronization signal block. The tracking reference signals may have the same subcarrier spacing as synchronization signals and may be punctured in the frequency domain. Alternatively, the tracking reference signals may include common control reference signals transmitted periodically with paired reference signals in a data channel. The common control reference signals and paired reference signals may be transmitted regardless of the presence of control or data. For improved tracking after a transition to a connected mode or a long discontinuous reception (DRX) cycle, a slot including tracking reference signals may be repeated or an additional tracking reference signal pattern may be transmitted.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a first plurality of control resources associated with a first transceiver node and a second plurality of control resources associated with a second transceiver node. The UE may select, based at least in part on a decoding limit for the UE, a decoding configuration to use for decoding one or more control resources from the first plurality of control resources and one or more resources from the second plurality of control resources. The UE may decode control signals received over control resources from the first plurality of control resources and the second plurality of control resources according to the decoding configuration.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may operate in a radio resource control (RRC) inactive state of a discontinuous reception (DRX) mode. The UE may identify, based at least in part on the UE operating in the RRC inactive state, a single frequency network (SFN) for a notification zone that is configured for the UE, the notification zone comprising a plurality of cells. The UE may receive one or more synchronization signal blocks (SSBs) broadcast by the plurality of cells over the SFN. The UE may perform a channel measurement procedure based at least in part on the one or more SSBs received over the SFN.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a first message indicating a plurality of measurement configurations, each measurement configuration of the plurality of measurement configurations may include different sets of measurement parameters used for measuring a reference signal (RS) of a cell. The UE may also receive, from the base station, a second message indicating that the UE activate a first measurement configuration, deactivate the first measurement configuration, or switch to the first measurement configuration, where the first measurement configuration is from the plurality of measurement configurations. The UE may determine a measurement reporting scheme based at least in part on the indication to activate, deactivate, or switch to the first measurement configuration.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive multiple uplink grants that schedule uplink transmissions for two different radio access technologies (RATs) during overlapping time resources. The UE may adjust the power for one of the uplink transmissions based on the temporal proximity of the second received uplink grant relative to the first uplink transmission. The UE may adjust the power of the uplink transmission by partially or completely reducing its power.
