Abstract: Methods, systems, and devices for wireless communications are described. A number of blind decodings of a search space set for control information are defined. A search space of the search space set includes a subset of blind decodings. A reduction factor is determined. The reduction factor is applied to the subset of blind decodings to obtain a reduced subset of blind decodings for the search space. A reduced number of blind decodings of the search space set is identified based at least in part on the reduced subset of blind decodings for the search space. The control information is transmitted in a decoding candidate of the reduced number of blind decodings of the search space.

Abstract: Methods, systems, and devices for wireless communication are described. In one example, a base station may dynamically configure a user equipment (UE) to monitor or avoid monitoring for a preemption indication. Accordingly, the UE may have a lower chance of monitoring for a preemption indication when it is unlikely that an uplink or downlink transmission will be preempted. In another example, a base station may transmit a control message indicating whether future indications received from the base station are to be interpreted as preemption indications or permission indications. Accordingly, the base station may choose to use either preemption indications or permission indications (e.g., based on the probability of collisions between mobile broadband (MBB) and low latency transmissions) to facilitate MBB and low latency communication multiplexing with limited signaling.

Abstract: Aspects of the present disclosure describe receiving synchronization signals in wireless communications. A block of synchronization signals can be received from a base station in a first time interval. A beam identifier and a redundancy version associated with the block of synchronization signals can be determined. A broadcast channel can be received based at least in part on a timing associated with the beam identifier. The broadcast channel can be descrambled based at least in part on a scrambling code associated with the redundancy version.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may obtain access to a base station by performing an initial access procedure within an initial access bandwidth. In some cases, the UE may monitor for a cell specific configuration in the initial access bandwidth that indicate one or more first common search spaces within the initial access bandwidth that the UE may monitor for control information. Additionally, the UE may receive dedicated signaling after the initial access procedure that indicates a downlink bandwidth part (BWP) and one or more second common search spaces within the downlink BWP to monitor for control information. Accordingly, the UE may monitor the first common search spaces, the second common search spaces, or both based on the dedicated signaling.

Abstract: Techniques for monitoring for control information in sets of downlink control channel resources are described, where multiple sets of downlink control channel resources may overlap. The described techniques include monitoring for one or more search spaces in a set of downlink control channel resources by rate matching downlink control channel resources independently of other sets of downlink control channel resources. Alternatively, overlapping sets of downlink control channel resources may be rate-matched accounting for reference signals of overlapping sets of downlink control channel resources.

Abstract: Methods, systems, and devices for wireless communications are described that provide for selection of different sets of transmission beams by a user equipment (UE) for establishing beamformed communications with a base station. Each transmission beam of a first set of transmission beams may have corresponding uplink random access channel (RACH) resources. A UE may monitor for transmission beams from a base station and select a first transmission beam of the first set for communications with the base station. As part of a connection establishment, the base station may provide configuration information that indicates a second set of transmission beams that includes each transmission beam of the first set of transmission beams and at least an additional transmission beam. In some cases, the additional transmission beam may be mapped to a first RACH resource that also corresponds to a first transmission beam of the first set of transmission beams.

Abstract: Methods, systems, and devices for wireless communications are described. A transmission reception point (TRP) may determine a configuration for downlink transmission of group-common control information associated with a plurality of TRPs. The TRP may identify a set of downlink resources allocated for transmission of the group-common control information. A user equipment (UE) may receive the configuration from at least one TRP of the plurality of TRPs. The UE may monitor downlink resources for reception of the group-common information based on the configuration. The TRP may transmit, and the UE may receive, the group-common control information over the downlink resources. The group-common control information may indicate communication parameters for communications between the UE and at least one TRP.

Abstract: Power control in new radio (NR)-to-NR dual connectivity communications is disclosed. A UE, compatible for NR-to-NR dual connectivity, may receive a transmit power configuration and a power allocation configuration. The transmit power configuration identifies the designated reserved power for each of the cell groups participating in the dual connectivity communication. The power allocation configuration identifies to the UE whether to operate access to excess transmission power by either mode 1 rules, which may introduce phase discontinuity into ongoing transmissions, or mode 2 rules, which use a look-ahead functionality to trigger joint determination and allocation of transmission power among known uplink transmissions over a given transmission duration. After the determined transmission power allocation has been made, the UE transmits the dual connectivity transmissions according to the determined power.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive downlink control information within a control resource set (CORESET) configured with a wideband demodulation reference signal (DMRS) and including disjoint segments of resource blocks (RBs). The downlink control information may be located at least partially within a first segment of the disjoint segments and a second segment of the disjoint segments may be exclusive of the downlink control information. The downlink control information may include a grant of a set of resources for a downlink shared channel that overlaps with the CORESET. The UE may determine a rate matching operation for the wideband DMRS for a downlink shared channel for portions of the set of resources that overlap with the second segment of the disjoint segments, and receive the downlink shared channel on the set of resources according to the determined rate matching operation.

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 receive one or more synchronization signal blocks (SSBs) over a serving single frequency network (SFN) for a first notification zone, wherein the first notification zone comprises a plurality of cells. The UE may perform a channel measurement procedure using the received one or more SSBs. The UE may determine, based at least in part on a result of the channel measurement procedure, that a channel performance metric for the serving SFN of the first notification zone fails to satisfy a threshold. The UE may perform a cell reselection procedure to identify a cell of a neighboring SFN for a second notification zone that has a channel performance metric satisfying the threshold.
