Abstract: Methods, systems, and devices for wireless communications are described. A wireless communications device, such as a user equipment (UE) may transmit a capability message indicating a capability of the UE to receive one or more downlink messages during a time slot, and may receive one or more control signalings which schedule a first and a second downlink message during the time slot, indicate a first resource allocation scheduled by a first scheduling configuration, and indicate a second resource allocation scheduled by a second scheduling configuration. The UE may monitor for one or both of the first downlink message or the second downlink message during the time slot based on the one or more control signalings and the capability message. The capability message may indicate a capability of the UE to receive a single downlink message or receive more than one downlink message during the time slot.

Abstract: Certain aspects of the present disclosure provide techniques for transmitting downlink control information (DCI) to schedule retransmissions of semi-persistently scheduled (SPS) physical downlink shared channels (PDSCHs) that were not successfully received. A method that may be performed by a user equipment (UE) includes receiving a downlink control information (DCI) that schedules retransmission of at least two semi-persistently scheduled (SPS) physical downlink shared channels (PDSCHs) that have hybrid automatic retransmission request (HARD) identifier (IDs); and receiving the retransmissions of the at least two PDSCHs.

Abstract: Wireless communications systems and methods related to multiplexing of synchronization blocks (SSBs), control resource sets (CORESETs), and system information blocks (SIBs) are provided. A user equipment (UE) receives, from a base station (BS), a first SSB of a first group of SSBs of an SSB burst set, wherein the first group of SSBs and a second group of SSBs of the SSB burst set are spaced apart in time by a group of CORESETs and SIBs. The group of CORESETs and SIBs comprises one CORESET and at least one SIB for each SSB of the first group of SSBs. The UE receives, in a first CORESET of the group of CORESETs and SIBs based on the first SSB, SIB scheduling information. The UE receives, based on the SIB scheduling information, a first SIB of the group of CORESETs and SIBs.

Abstract: Methods, systems, and devices for wireless communications are described in which a user equipment (UE) may transmit a random access message (e.g., msgA or msg3) using a modulation and coding scheme (MCS) selected based on the frequency band and subcarrier spacing utilized for the random access procedure. The MCS may depend on the frequency band and a size of the SCS satisfying a threshold. In some cases, a base station may select and indicate the MCS for the UE. Additionally or alternatively, a phase tracking reference signal may be transmitted along with a random access message to correct for phase noise.
