Abstract: Certain aspects of the present disclosure provide techniques and apparats for remaining minimum system information (RMSI) physical downlink control channel (PDCCH) monitoring. A method for wireless communications by a user equipment (UE) is provided. During initial access of a cell, the UE determines a default first periodicity to monitor for at least a first PDCCH scheduling RMSI. After the initial access, the UE determines a second periodicity to monitor at least a second PDCCH scheduling RMSI based on the default first periodicity or based on an indication received in a previous RMSI from the cell. The UE monitors for at least the first PDCCH during initial access at the default first periodicity and monitors for at least the second PDCCH at the second periodicity after the initial access.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine a remaining minimum system information control resource set (RMSI CORESET) monitoring configuration based at least in part on information received by the UE in a first frame; and monitor, during a second frame and based at least in part on the RMSI CORESET monitoring configuration, for an RMSI CORESET based at least in part on a synchronization signal block (SSB), associated with the RMSI CORESET, that is received in the first frame.

Abstract: Aspects of the present disclosure describe an indication channel for wireless communications that indicates whether an ultra-reliable low-latency communication (URLLC) transmission is present in an enhanced mobile broad band (eMBB) slot. A user equipment (UE) may receive an indication channel identifying one or more resources defined by time domain parts and frequency domain parts that have been punctured by an Ultra-Reliable Low latency Communication (URLLC) transmission. The number of frequency domain parts may be greater than or equal to two. The UE may determine a number of resource block groups (RBGs) in an active band width part (BWP) of the UE. The UE may map the RBGs in the BWP among each of a number of sub-bands equal to the number of frequency domain parts based on a pre-defined rule.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive multiple physical downlink control channels (PDCCHs) in one or more slots along with data traffic, where one of the PDCCHs includes a downlink preemption indication (DLPI) signifying that a portion of the data traffic was preempted. In some cases, the UE may monitor, within a same slot, for both the data traffic and an additional PDCCH carrying the DLPI and then transmit, within the same slot, a feedback message based on attempting to decode the data traffic, taking into account the DLPI. Additionally, the UE may receive the data traffic via a first service, where the DLPI indicates a second service preempts the first service. In some cases, the DLPI may be transmitted based on the UE being capable of processing the data traffic and transmitting the feedback message within the same slot.

Abstract: The present disclosure relates to signaling information in physical broadcast channel (PBCH) demodulation reference signals (DMRS). In one example, a network entity may transmit the signaling information carried by a DMRS in one or more resource elements of physical broadcast channel (PBCH) symbols within a bandwidth of a primary synchronization signal and a secondary synchronization signal of a synchronization signal block. In another example, a user equipment (UE) may receive the signaling information carried by the DMRS within one or more resource elements of PBCH symbols within a bandwidth of a primary synchronization signal and a secondary synchronization signal of a synchronization signal block on a broadcast channel from the network entity.

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 some cases, due to blind decoding and channel estimation (CE) limits, one or more user equipment (UE) specific search sets may be pruned for blind decoding and/or CE purposes. For instance, after hashing a set of common decoding candidates to control channel elements (CCEs) within the control region, the UE specific search sets may be pruned so as to conform to the blind decode limitation, since a common search space has already occupied a portion of the total blind decode limit. Following pruning, the UE may hash the sets of UE-specific decoding candidates associated with the one or more UE specific search sets to CCEs within the control region. The UE may further prune UE specific search sets, based on CE limits, while reusing CE for overlapping hashed locations.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive when operating in a network that provides synchronization signals at a plurality of locations in a channel bandwidth, a common search space (CSS) indicator for a synchronization signal, wherein the CSS indicator indicates that the synchronization signal is not associated with a CSS for a downlink control channel. The user equipment may determine a location of the CSS for the downlink control channel based at least in part on the CSS indicator. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive one or more power saving signals based at least in part on a selected power saving signal configuration of a set of power saving signal configurations, wherein the UE stores information identifying the set of power saving signal configurations; and perform a power saving operation based at least in part on the one or more power saving signals. In some aspects, a base station may determine one or more power saving signal configurations, of a set of power saving signal configurations, to be used to transmit one or more power saving signals; and transmit the one or more power saving signals using the one or more power saving signal configurations. Numerous other aspects are provided.
