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: Aspects of the present disclosure relate to wireless communications and, more particularly, to linkage of packet transmissions for ultra-reliable low-latency communications (URLLC) in new radio (NR). A method for wireless communications that may be performed by a user equipment (UE) is provided. The method generally includes receiving a current transmission of a packet; determining, based on the current packet transmission, one or more previous transmissions of the packet occurred and at least one parameter associated with the one or more previous transmissions; and combining the current packet transmission with the previous transmissions based, at least in part, on the determination.

Abstract: Dynamically adaptive numerologies for ultra-reliable low-latency communications (URLLC) are discussed in which a base station may determine performance characteristics for each user equipment (UE) that it serves, in addition to detecting any fluctuations in system loading at the base station. Based on this information, the base may be select for each of the served UEs an adapted numerology that provides an optimized set of configurations that assist the communications between the base station and each UE to meet the strict parameters for URLLC. Once selected, the base station signals the selected adapted numerology to the UEs either through broadcast or UE-specific communications.

Abstract: A method and apparatus for reporting delay budgets for Ultra-Reliable Low-Latency Communications (URLLC) uplink transmissions during wireless communications are described. The method and apparatus include receiving one or more URLLC data packets at a medium access control (MAC) buffer of a user equipment (UE), the one or more URLLC data packets scheduled for transmission to a network entity. The method and apparatus include determining a delay budget for the one or more URLLC data packets at the MAC buffer, the delay budget including information corresponding to an expiration of a transmission deadline. The method and apparatus include transmitting the delay budget to the network entity to allocate resources on an uplink data channel such that transmissions of the one or more URLLC data packets from the UE to the network entity satisfy a reliability threshold.

Abstract: Techniques for transmission of Ultra-Reliable Low-Latency Communications (URLLC) data over Time Division Duplex (TDD) using a URLLC configuration for a TDD subframe are disclosed. The techniques include determining that data scheduled for transmission using a TDD band over a TDD subframe includes Ultra-Reliable Low-Latency Communications (URLLC) data, and in response, utilizing a URLLC subframe configuration for the TDD subframe. The URLLC subframe configuration includes downlink intervals and uplink intervals.

Abstract: Aspects of the present disclosure provide a scheduling entity for facilitating Multiple Input Multiple Output (MIMO) wireless communication by dynamically assigning ranks to scheduled entities for each sub-band of a slot. In some examples, the rank assigned to a particular scheduled entity may be increased or decreased between sub-bands of the slot based on the amount of scheduled user data traffic for that particular scheduled entity relative to the amount of scheduled user data traffic for other scheduled entities. The scheduling entity further schedules resources within the sub-bands of the slot based on the assigned ranks and transmits an enhanced control channel providing scheduling information indicating the scheduled resources to the scheduled entities.

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: 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: 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.

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: 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.
