Abstract: Methods, systems, and devices for wireless communications are described. As described herein, a service type may be configured, activated, and utilized for subsequent communications according to the service type. For example, a user equipment (UE) may monitor a downlink control channel associated with the service type based on configuring the service type and activating the service type, receive downlink messages associated with the service type, or transmit uplink messages associated with the service type. In some cases, the service type may be activated by transmitting a medium access control (MAC) control element (CE) or a downlink control information (DCI) message. When traffic associated with the service type is no longer present, the service type may be deactivated based on a deactivation indication and/or a deactivation timer. In some cases, the service type may include an ultra-reliable low latency communication (URLLC) service or a low latency service.

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: Certain aspects of the present disclosure generally relate to wireless communication. In some aspects, a first base station for wireless communication, associated with a first radio access technology (RAT), may generate a message to cause a user equipment to wake up from a power saving state or to reconfigure a cycle associated with the power saving state, wherein the message includes an indication that the user equipment is to wake up from the power saving state or to reconfigure the cycle; and/or transmit the message toward the user equipment via a second base station, associated with a second RAT and the user equipment, to cause the user equipment to wake up from the power saving state or reconfigure the cycle. Numerous other aspects are provided.

Abstract: Techniques are described for wireless communication. A method for wireless communication at a user equipment (UE) includes receiving, by the UE, a first transmission on a beam over a radio frequency spectrum during a first time interval. The first transmission includes an indication of a subsequent physical downlink control channel (PDCCH) transmission on the beam. The indication includes information about a PDCCH in a second time interval subsequent to the first time interval. The method also includes configuring a power saving state of the UE based at least in part on the indication. A method for wireless communication at a network access device includes transmitting the first transmission to at least one UE, and transmitting the PDCCH during the second time interval.

Abstract: New radio (NR) power headroom report (PHR) design for millimeter wave (mmWave) deployment is discussed. The power control process for mmWave may include beam-specific periodic PHR reporting and user equipment (UE)-specific event-trigger PHR reporting. The periodic PHR reporting may either provide a single PHR that includes power headroom information for each of the serving beams, or the UE may be configured to measure and report PHR for different beams in different slots. When reporting a single PHR with power headroom information for multiple serving beams, a beam index may be included in the reserved bits of the PHR. For the event-trigger PHR, the PHR reported based on a detected event trigger may provide power headroom information only for the current serving beam, or for all serving beams.

Abstract: Certain aspects of the present disclosure provide techniques for an extended feature indication in new radio (NR), such as for slice specific extension (SSE). Aspects provide a method that may be performed by a transmitter device, such as a user equipment (UE) or a network node (e.g., a base station (BS)). The method generally includes determining a network node supports an extended feature, the extended feature being associated with an extended feature identifier. The transmitter device transmits a message, the message including the extended feature identifier and an indication that the apparatus is using the extended feature. A receiver device can receive the message and process the message and/or one or more subsequent messages based on the indication that the transmitter device is using the extended feature and the extended feature identifier.

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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine that uplink data associated with a first quality of service flow is available for transmission to a base station. The UE may transmit a buffer status report to the base station. In some examples, the buffer status report may include a buffer status of the first quality of service flow. The UE may then receive an uplink grant based on transmitting the buffer status report, and may transmit the uplink data based on the uplink grant.

Abstract: Methods, systems, and devices for wireless communication are described that provide for a single bit or multiple bit scheduling request (SR). The SR may be transmitted by a user equipment (UE) to a base station and may indicate that the UE has data to be transmitted to the base station. The SR may include an indication of the priority level associated with the data to be transmitted to the base station, which may be based on the data type, logical channel, or numerology associated with the data to be transmitted to the base station.

Abstract: Wireless communication devices, systems, and methods related to communicating CSI reports during a discontinuous reception (DRX) are provided. For example, a method of wireless communication may include performing one or more measurements of one or more reference signals configured for a user equipment (UE). The method may also include triggering transmission of a channel state information (CSI) report during a DRX cycle. The method may further include transmitting to a base station (BS), the CSI report based on the triggering, the CSI report including the one or more measurements.
