Abstract: In some circumstances, a URLLC may preempt resource. An apparatus may be configured to receive a set of resource blocks from a base station including at least one of eMBB data or URLLC data in a PDSCH. The apparatus may receive a URLLC indicator from the base station. The URLLC indicator may be received embedded within the URLLC data or received separate from the URLLC data within DCI of a PDCCH. The URLLC indicator indicates whether the set of resource blocks includes at least part of the URLLC data. The apparatus may determine, based on the URLLC indicator, whether the set of resource blocks includes the URLLC data and processing the set of resource blocks based on a result of determining whether the set of resource blocks includes the URLLC data.

Abstract: Various types of communication may switch from an unlicensed spectrum to a licensed spectrum. MiCr communication may be synchronized based on transmission time intervals (TTIs), which may improve the duration required to switch between bands. A MiCr system may transmit a signal to temporarily suspend other traffic in a licensed band so that MiCr communication may occur. For example, an apparatus may be configured to determine synchronization between a first radio access technology (RAT) and a second RAT based on transmission time intervals associated with the first RAT and transmission time intervals associated with the second RAT, switch from the first RAT to the second RAT after the determined synchronization between the first RAT the second RAT; and transmit, during a TTI associated with the second RAT, a first packet using the second RAT based on the switch from the first RAT to the second RAT.

Abstract: Methods, systems, and devices for wireless communications are described that support evolved semi-persistent scheduling (SPS) for wireless communications. A base station may configure SPS in which multiple time intervals are scheduled, each time interval including multiple slots that may be scheduled by different uplink or downlink resource allocations. The SPS configuration may include an ON-OFF duty cycle where an ON portion of the duty cycle spans a portion of a time interval and includes uplink and downlink resources, and an OFF portion of the duty cycle spans a remaining portion of the time interval and does not include any allocated SPS resources. Such SPS configurations may be used, for example, for transmitting sensor data and command information between controllers and sensors/actuators in a factory automation network.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit, and a user equipment (UE) may receive a group physical control channel signaling, which may configure grant uplink transmissions for a set of UEs including the receiving UE. The group physical control channel signaling may indicate allotted resources for configured grant uplink transmissions. The group physical control channel signaling may further indicate a group physical control channel which a UE may monitor for control messages. The UE may transmit a configured grant uplink transmission in accordance with the group physical control channel signaling. The base station may receive the configured grant uplink transmission and may determine a control message which it may transmit in the group physical control channel based on the configured grant uplink transmission. The UE may receive the control message, and may determine whether to retransmit a configured grant uplink transmission based thereon.

Abstract: In an embodiment, a transmission reception point (TRP) apparatus of a Coordinated Multipoint (CoMP) network, determines a periodicity of periodic traffic between the TRP apparatus and a user equipment (UE), and schedules a Channel State Information (CSI) process in advance of a traffic window for a next instance of the periodic traffic in accordance with the determined periodicity. In another embodiment, the UE of the CoMP network performs the CSI process in advance of the traffic window for the next instance of periodic traffic between the UE and the TRP apparatus, the CSI process being scheduled in accordance with the determined periodicity of the periodic traffic.

Abstract: Methods, systems, and devices for wireless communications are described. One method may include an eNB predetermining a plurality of bandwidth parts to monitor based on resource reservation information received from at least one base station, and transmitting information indicative of the predetermined bandwidth parts in a radio resource control (RRC) message. In some cases, a base station may transmit information indicative of predetermined bandwidth parts including a monitoring schedule to monitor either the first bandwidth part or the second bandwidth part in a timeslot of a set of timeslots. Another method may include receiving a predetermined monitoring schedule from a base station, and selecting a plurality of bandwidth parts to monitor on a physical downlink control channel based on the received schedule.

Abstract: Methods, systems, and devices for wireless communication are described. A base station may identify a first grant repetition configuration of a plurality of grant repetition configurations for a user equipment (UE). The base station may generate a grant repetition parameter corresponding to the first grant repetition configuration. The base station may transmit the grant repetition parameter to the UE to indicate the first grant repetition configuration. The base station may transmit a repetition of grants in accordance with the first grant repetition configuration. The UE may receive the grant repetition parameter from the base station and determine a grant repetition configuration corresponding to the grant repetition parameter. The UE may monitor for a repetition of grants corresponding to the determined grant repetition configuration.

Abstract: A method, a computer-readable medium, and an apparatus are provided for wireless communication at a UE. The apparatus attempts to receive a downlink transmission from a base station and determines to transmit a NACK to the base station for the downlink transmission. The UE transmits the NACK to the base station in a common resource in an uplink control channel, wherein the common resource is common to multiple UEs communicating with the base station. The UE may also transmit the NACK using a resource granted to the UE in the uplink control channel. Thus, the transmission of the NACK in the common resource may comprise a repetition of the NACK transmitted using the resource granted to the UE. The common resource may comprise a Non-Orthogonal Multiple Access (NOMA) resource. Thus, the UE may apply a NOMA sequence to the NACK prior to transmission of the NACK in the common resource.

Abstract: Various aspects are described for schemes that address the potential puncturing of important reference signals (RSs) for enhanced mobile broadband (eMBB) applications, such as demodulation reference signal (DMRS), channel state information reference signal (CSIRS), tracking reference signal, and general reference signal. The schemes can be used for recovery of eMBB's RS puncturing from dynamic multiplexing of ultra-reliable-low-latency communications (URLLC) and eMBB. The schemes include a block-based scheme and an over-provisioning scheme. The schemes modify an existing RS pattern before puncturing occurs in response to a presence of the URLLC traffic. In addition, there can be an option not to use (e.g., disable) time-domain orthogonal cover code (TD-OCC) for the RSs.

Abstract: A first apparatus may puncture, in at least two subslots, a first type of data or control information with a second type of data or control information. The first apparatus may bundle the least two subslots within a subframe, and the subframe may include a portion for carrying acknowledgment (ACK)/negative acknowledgment (NACK) information associated with the second type of data or control information. The first apparatus may communicate with a user equipment (UE) during the at least two subslots within the subframe. A second apparatus may receive ACK/NACK information associated with a second type of data or control information. The second apparatus may reduce a transmission power for a first type of data or control information during a subsequent subframe when the ACK/NACK information indicates a negative acknowledgement.
