Abstract: Certain aspects of the present disclosure provide techniques and apparatus for signaling channel preemption indications that enable a user equipment (UE) of a first type to take one or more actions on resources that are re-allocated to an UE of a second type. An exemplary method generally includes determining that resources allocated for a scheduled transmission by a first user equipment (UE) of a first type overlaps with uplink channel resources allocated to a second UE of a second type. The method also includes signaling, based on the determination, an uplink preemption indication (ULPI), to the second UE, that identifies at least some of the overlapping resources.

Abstract: Systems and techniques are disclosed for selecting service-specific cells that considers additional information about service availability at the cells. A base station stores service availability information in system information. A UE searching for a service-specific cell on which to camp receives the system information with service availability. The UE analyzes its service requirements against the service availability as well as measured radio conditions and selects a cell that enables service-specific support on which to camp. When a change occurs to availability of the service support at the base station, it notifies the camped UE of the change and the UE obtains the changed system information to determine whether to reselect a different cell on which to camp. When a service-specific cell is not available, the UE may select a suitable cell for normal service and periodically perform cell reselection in an attempt to again camp on a service-specific cell.

Abstract: Certain aspects of the present disclosure provide techniques for physical downlink shared channel (PDSCH) processing in presence of downlink preemption indication (DLPI). A method for wireless communication by a base station (BS) includes determining a feedback timing indicator associated with a PDSCH transmission to a user equipment (UE) in a first slot. The determination is based on a first number of slots from the first slot until transmission of a DLPI to the UE in a second slot and a second number slots for a minimum processing time associated with the UE. The method includes sending downlink control information (DCI) to the UE scheduling the PDSCH transmission to the UE in the first slot. The DCI includes the feedback timing indicator. The UE determines how to process the PDSCH based on the feedback timing indicator.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless communication network may support mission critical (MiCr) communications and mobile broadband (MBB) communications with hybrid multiplexing (e.g., time division multiplexing (TDM) and frequency division multiplexing (FDM)). A base station may identify a first set of resources allocated for MiCr communications and a second set of resources allocated for MBB communications. The first and second set of resources may be multiplexed in the frequency domain, and the base station may transmit MiCr information over the first set of resources under normal data traffic conditions. As data traffic or other conditions associated with MiCr communications change, the base station may schedule MiCr transmissions on the second set of resources allocated for MBB communications, by puncturing the second set of resources for the MiCr communications.

Abstract: A method, an apparatus, and a processor-readable storage medium for wireless communication are provided. In an aspect, the apparatus is a subordinate entity that receives an indication of a resource allocated for an uplink transmission. The subordinate entity also receives a condition associated with the resource. The subordinate entity evaluates whether the condition is satisfied and determines whether to transmit a packet using the resource based on the condition being satisfied. In another aspect, the apparatus is a scheduling entity that generates an indication of a resource allocated for an uplink transmission. The resource is associated with a condition that limits access to the resource. The scheduling entity transmits the indication and the condition to a subordinate entity and receives a packet from the subordinate entity via the resource based on the condition being satisfied.

Abstract: Various aspects of the present disclosure provide for enabling at least one opportunity to transmit mission critical (MiCr) data and at least one opportunity to receive MiCr data in a time division duplex (TDD) subframe during a single transmission time interval (TTI). The single TTI may be no greater than 500 microseconds. The TDD subframe may be a downlink (DL)-centric TDD subframe or an uplink (UL)-centric TDD subframe. How much of the TDD subframe is configured for the at least one opportunity to transmit the MiCr data and how much of the TDD subframe is configured for the at least one opportunity to receive the MiCr data may be adjusted based on one or more characteristics of the MiCr data. The MiCr data may have a low latency requirement, a high priority requirement, and/or a high reliability requirement. Various other aspects are provided throughout the present disclosure.

Abstract: Transmission time interval (TTI) bundling for ultra-reliable low-latency communication (URLLC) uplink and downlink transmissions is discussed in which a base station or user equipments (UEs) determine conditions for one or more served UEs that would indicate enabling TTI bundling for data and/or control transmissions. The serving base station transmits an enablement signal signifying that TTI bundling will be performed for data and/or control transmissions. The enablement signal may include a bundle length for the transmission bundle. The data or control signal packets may then be repeatedly transmitted to the UEs a number of times corresponding to the bundle length.

Abstract: Coding for bursty interference is discussed in which a base station receives data bits for transmission. The base station may generate code blocks including information bits and parity bits. The base station may also generate parity check code blocks including information bits corresponding to information bits of the generated code blocks. The base station may transmit the code blocks and the parity check code blocks to a mobile device to improve decoding. When errors are detected, the mobile device may decode the received code blocks using hard or soft parity checks and the parity check code blocks.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine to report first channel state information (CSI), wherein the first CSI is associated with a parameter that indicates a priority of the first CSI. The UE may prioritize the first CSI over a second CSI based at least in part on the parameter. The UE may transmit an indication of the first CSI and may drop the second CSI based at least in part on prioritizing the first CSI over the second CSI. Numerous other aspects are provided.

Abstract: The disclosure relates in some aspects to a scalable transmission time interval (ITO and hybrid automatic repeat request (HARQ) design. The TTI is scalable to, for example, achieve latency and/or efficiency tradeoffs for different types of traffic (e.g., mission critical traffic versus traffic with more relaxed latency requirements). In the event a longer TTI is employed, various techniques are disclosed for ensuring a fast turn-around HARQ, thereby maintaining a high level of communication performance.
