Abstract: Methods, systems, and devices for increasing the reliability of low latency transmissions are described. For example, multiple control messages and/or multiple data messages may be transmitted for a single transport block. Explicit and/or implicit signaling may be used to support the repetition of control and data transmissions in a low latency environment. For example, explicit signaling may be used to indicate a correspondence between repeated control and/or data messages. Additionally or alternatively, particular configurations may be used to implicitly signal a correspondence between repeated control and/or data messages.

Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a transmitting device may be configured to transmit a transport block in a set of transmission time intervals (TTIs) of a repetition window to improve the chances that the transport block is received by a receiving device. In some cases, however, the transport block may not be available to be transmitted in the repetition window until after a first TTI of the repetition window. In such cases, a transmitting device may use the techniques described herein to identify appropriate configurations for transmitting the transport block in the repetition window. For example, the transmitting device may identify an adjusted redundancy version sequence to use for transmitting the transport block in the repetition window or the transmitting device may adjust a repetition window based on a TTI in which the transport block is available to be transmitted.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may transmit, and a user equipment (UE) may receive, a group-common downlink control information (DCI) message, wherein the group-common DCI message includes information identifying at least one communication parameter for a plurality of UEs. The BS and the UE may communicate in accordance with the at least one communication parameter based at least in part on the BS transmitting the group-common DCI message to the plurality of UEs and the UE receiving the group-common DCI message. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described that provide for service indication via downlink control information (DCI) in which different services have a same DCI size. Techniques provide also that a DCI format may be indicated by a masking operation on a cyclic redundancy check (CRC) of the DCI. The DCI may include an indicator field that may indicate the service of the associated operation. The indication may also be provided via different monitoring occasions of the DCI transmissions that are associated with different services. Different DCI search spaces also may be associated with different services and provide the service indication. Additionally or alternatively, different scrambling sequences used on all or a portion of control information or demodulation reference signal transmissions may be associated with different services.

Abstract: Techniques are described herein related to communicating a quality of service (QoS) class identifier (QCI) for configuring physical (PHY) layer signaling. The QCI may be used to configure one or more transmission parameters of a device (e.g., a user equipment (UE) or a base station) at a PHY layer. The PHY layer may select the one or more transmission parameters to meet the QoS conditions of a given QoS class of a transport block being communicated. A modulation and coding scheme (MCS) value may be used as the QCI for the PHY layer, a channel quality indicator (CQI) value may be used as the QCI for the PHY layer, or a cell radio network temporary identifier (C-RNTI) may be used as the QCI for the PHY layer. In some cases, the QCI may be a single bit included in a downlink control message.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a block error rate (BLER) target for communications associated with the user equipment; determine a resource allocation pattern for transmission of channel state information reference signals (CSI-RS) based at least in part on the BLER target; and monitor one or more resources, indicated by the resource allocation pattern, for the CSI-RS. Numerous other aspects are provided.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a physical uplink control channel (PUCCH) transmission is associated with a first type of service or a second type of service, wherein the second type of service is associated with a higher reliability or a lower latency than the first type of service. The UE may transmit the PUCCH transmission using a first set of resources when the PUCCH transmission is associated with the first type of service or using a second set of resources when the PUCCH transmission is associated with the second type of service. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to methods and apparatus for rate-matching a stream of bits encoded using polar codes. An exemplary method generally includes determining, based on a time of a transmission, a redundancy version (RV) of data to be transmitted in the transmission and transmitting the determined RV of the data via a wireless medium at the time.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use easily detectable transmission parameters to infer difficult-to-detect parameters for communications with a base station. For example, the base station may provide the UE with multiple sets of transmission parameters, and the UE 115 may choose from among these sets of transmission parameters for the communications. In some cases, the UE may be configured with a reference set of transmission parameters, receive one or more transmission parameters that are different relative to the reference set of transmission parameters, and then determine to use the different transmission parameters for the communications. Additionally or alternatively, the multiple sets of transmission parameters may be specified for a certain uplink message (e.g., random access channel messages), where the UE selects the transmission parameter set based on one or more characteristics of the uplink message.
