Abstract: Methods, systems, and devices for wireless communications are described. A network entity may transmit a set of spatially multiplexed synchronization signals in a same symbol period. The set of spatially multiplexed synchronization signals may indicate a parameter, such as a cell identifier, for the network entity. The network entity may select a sequence for each synchronization signal of the set. A user equipment (UE) may monitor for the set of spatially multiplexed synchronization signals during the same symbol period. The UE may differentiate each synchronization signal based on a respective sequence used to transmit each synchronization signal. The UE may determine that the set of spatially multiplexed synchronization signals were transmitted by the network entity using multiple antenna ports. The UE may determine the parameter for the network entity based on receiving the set of spatially multiplexed synchronization signals.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a user equipment (UE) and a network entity may utilize multi-port mobility reference signals to assist with spatial based mobility procedures. The UE may receive a reference signal that is associated with multiple antenna ports. The UE may measure a multi-dimensional channel response based on the reference signal. The multi-dimensional channel response may be associated with measured channel metrics corresponding to the multiple antenna ports. The UE may transmit a report that includes a channel measurement vector based on the multi-dimensional channel response. The channel measurement vector may indicate multiple measured channel metrics for one or more dimensions of the multi-dimensional channel response. The network entity may transmit a message that indicates one or more metrics associated with mobility management for the UE based on the report that indicates the channel measurement vector.

Abstract: Systems and methods for scheduling uplink transmissions are disclosed. In an aspect, a user equipment (UE) receives a downlink control information signal, wherein the downlink control information indicates an uplink grant for multiple contiguous nominal uplink repetitions, identifies resources allocated for the multiple contiguous nominal uplink repetitions based on the uplink grant, wherein the identified resources include first resources for a first actual repetition of uplink data and second resources for a second actual repetition of uplink data, transmits the first actual repetition of uplink data using the first resources, and transmits the second actual repetition of the uplink data using the second resources.

Abstract: Methods, systems, and apparatuses for wireless communication are described. In some wireless systems (e.g., new radio (NR) systems), a system may employ fixed or variable length uplink burst regions (e.g., in an uplink-centric slot). The base station may semi-statically or dynamically configure a user equipment (UE) or group of UEs for uplink control channel transmissions within an uplink burst region. In semi-static configuration, the UE may determine the uplink control channel transmission based on values transmitted or indicated via higher-layer signaling or based on default values. In dynamic configuration, the UE may receive an indication of actual resources used by the base station in a physical layer message. The UE may transmit using an uplink control channel transmission based on the indication. In some cases, the base station may allocate code division multiplexing (CDM) groups based on which UEs are semi-statically configured and which are dynamically configured.

Abstract: Methods, systems, and devices for wireless communications are described for channel measurements for multiple uplink carriers in carrier aggregation (CA). A CA configuration may provide a first downlink carrier, a first uplink carrier, and a second uplink carrier. The second uplink carrier may be a supplemental uplink (SUL) carrier that does not have an associated downlink carrier in a same frequency band. A measurement downlink carrier may be configured and associated with the second uplink carrier, and measurements of a reference resource of the measurement downlink carrier may be used to determine transmission parameters of the second uplink carrier.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, using a set of resources that are shared between a first radio access technology (RAT) and a second RAT, control signaling that includes a dynamic spectrum sharing (DSS) configuration for a shared data channel. The UE may receive one or more indicators associated with the first RAT, the second RAT, or both, to coordinate communications for the shared set of resources. The UE may communicate with the network using the first RAT or the second RAT based on applying one or more of the indicators. To further support DSS, the UE may transmit UE capability information to indicate whether the UE is capable of DSS for the first RAT and the second RAT, and may apply one or more multiplexing modes for communications using the first RAT and the second RAT.

Abstract: Apparatus, methods, and computer program products for decoding are provided. An example method may include receiving a communication from a second network entity via a channel, where the communication is encoded based on multi-level coding associated with at least a first coding level and a second coding level, and where the first coding level is associated with a first set of bits and the second coding level is associated with a second set of bits. The example method may further include means for generating a first estimate of a first LLR associated with the first coding level, a second estimate of a second LLR associated with the second coding level, and auxiliary information including a third estimate of a third LLR based on the first set of bits and the second set of bits.

Abstract: Certain aspects of the present disclosure provide techniques for compact downlink control information (DCI) signaling design for ultra-reliable low-latency communications (URLLC). A method for wireless communications performed by a base station (BS) is provided. The method generally includes generating DCI, the DCI scheduling at least one transmission, according to a first DCI format. The first DCI format is compressed relative to a second DCI format and includes a carrier indicator field (CIF) and/or a rate-matching indicator field. The BS transmits the DCI to a user equipment (UE). The UE communicates with the BS based on the received DCI.

Abstract: An apparatus may utilize an air interface to transmit and/or receive a transmission during a first TTI that includes a second set of data overriding a first set of data scheduled for transmission during the first TTI. The air interface may further be utilized to transmit and/or receive a transmission after a duration of time that is less than a total time duration of the first TTI that includes an override indicator that is at least partially embedded in a data portion of a subframe. The override indicator may be configured to indicate that the first set of data scheduled for transmission during the first TTI is overridden by the second set of data having the higher priority. The override indicator may be transmitted after the second set of data is transmitted. The one or more additional TTIs may be after the first TTI.
