Abstract: An apparatus may receive a master information block and a synchronization signal (SS) block on a PBCH. The MIB may indicate an allocation associated with a CORESET. The apparatus may receive remaining minimum system information (RMSI) configuration information carried in the CORESET based on the allocation associated with the CORESET. The apparatus may determine a position associated with a downlink data channel based on a first value indicated by one of the MIB or the SS block in the PBCH and based on a second value indicated by the RMSI configuration information. The apparatus may receive data carried on the downlink data channel based on the position associated with the downlink data channel.

Abstract: Methods, systems, and devices for wireless communications are described. A non-terrestrial network (NTN) device (e.g., a satellite, base station) may transmit, to a user equipment (UE), at a first frequency a synchronization signal block (SSB) that indicates a second frequency of a control resource set (CORESET) relative to the SSB, where the second frequency is based on one or more of: a CORESET bandwidth, a combination of a first parameter associated with a first portion of the SSB and a second parameter associated with a second portion of the SSB, or both. The UE may monitor the CORESET at the indicated second frequency for a downlink control channel transmission. The NTN device may transmit, to the UE, a downlink control channel transmission over the CORESET. The NTN device may transmit, to the UE, system information based on the downlink control channel transmission.

Abstract: Methods, systems, and devices for wireless communication are described. A base station and user equipment (UE) may use quasi co-located antenna ports for transmission and reception of synchronization and/or reference signals and positioning reference signals. For example, the base station may identify a quasi co-location relationship indicating that antenna ports of the base station used to transmit a synchronization signal are quasi co-located with antenna ports of the base station used to transmit a positioning reference signal. In some cases, the base station may transmit an indication of the quasi co-location relationship to the UE. Additionally, the UE may receive the synchronization signal and determine a receive beam for the UE to use to receive the positioning reference signal based at least in part on the received synchronization signal and the identified quasi co-location relationship. The UE may then receive a positioning reference signal using the determined receive beam.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive signaling indicating a configuration for communicating to the UE a random access response of a random access procedure. The configuration may indicate a first quantity of instances of control information associated with the random access response in a set of slots and a portion of the time window configured for the first quantity of instances. The UE may monitor the set of slots for instances of the control information and receive a second quantity of instances of the control information for the UE in a first subset of slots of the set of slots. The second quantity of instances may be less than the first quantity of instances. The UE may combine the instances of the control information from the first subset of slots and decode the random access response based on combining the instances.

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: Certain aspects of the present disclosure provide techniques and apparatus relating to designs for the remaining minimum system information (RMSI) control resource set (CORESET) and the other system information (OSI) CORESET. In certain aspects, a wireless communication device (e.g., user equipment) is enabled to determine the location of Type0-PDCCH common search space CORESET and the OSI CORESET in the frequency and time domains based on the location of the synchronization signal block (SSB) transmissions in the frequency and time domains. Determining the location of the RMSI CORESET and the OSI CORESET frequency and time resources enables the UE to receive the RMSI CORESET and the OSI CORESET, respectively.

Abstract: Methods, systems, and devices for wireless communications are described. For example, a user equipment (UE) may be configured to receive a downlink control message (e.g., an uplink grant) that schedules resources for transmitting repetitions of an uplink channel transmission, where each of the repetitions of the uplink channel transmission may correspond to a single transport block. The UE may determine a plurality of sounding reference signal (SRS) resources based on the downlink control message, and transmit different instances of the uplink channel transmission repetitions according to different SRS resources. The described examples for uplink repetitions may support various techniques for uplink coverage enhancement and diversity gains.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may generate a sequence for use in scrambling a PBCH. The base station may then partition the sequence into sub-sequences based on a number of SS blocks in a SS block group. The base station may then apply each sub-sequence of the sequence as a scrambling code for the bits associated with the PBCH of a different SS block within a SS block group and transmit at least one SS block scrambled with one of the sub-sequences. A user equipment may decode the PBCH based on the sequence.

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.
