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, an apparatus, and a non-transitory computer-readable medium for wireless communication are provided. The apparatus, which is associated with a first cell, may receive communication information of a second cell, wherein the communication information is associated with a transmission, of a base station associated with the second cell, to an ultra-reliable low latency communication (URLLC) user equipment (UE) located in the second cell; and/or reduce transmission power of the apparatus associated with the first cell, in at least one resource, to reduce interference with the transmission by the base station to the URLLC UE.

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. Further, the apparatus may transmit a silencing signal to suspend traffic in the second RAT.

Abstract: Methods, systems, and devices for wireless communication are described. Some wireless communications systems support mobile broadband (MBB) communications and low latency communications. To accommodate low latency communications, a base station may identify resources allocated for MBB communications, and the base station may reassign (or puncture) these resources for low latency communications. The base station may transmit an indication of the reassigned (or punctured) resources to one or more user equipments (UEs). The base station may transmit an indication of the reassigned resources over a designated indication channel during a time period that is being reassigned for low latency communications (e.g., using a current indication). The base station may also transmit another or complementary indication of the reassigned resources in a subsequent time period (e.g., using a post indication), which may include supplemental or additional information.

Abstract: Methods, systems, and devices for wireless communication for adaptive ultra-reliable low-latency communications (URLLC) semi-persistent scheduling (SPS) are described. One method includes determining a data packet payload size for a transmission using SPS resources in a transmission time interval (TTI). The method also includes sending a release signal to release a portion of the SPS resources in the TTI based on the size and transmitting the data packet during the TTI using unreleased SPS resources. Another method includes identifying that a packet profile of packets transmitted on SPS resources varies by more than a packet profile threshold and sending, based at least in part on the identifying, a request-to-update (RTU) signal to update the SPS resources. The method also include receiving a confirmation of receipt of the RTU signal and updating a resource allocation or a resource attribute based at least in part on the packet profile and confirmation of receipt.

Abstract: Techniques are described herein to provide priority traffic grant-less access to pre-defined communication resources that are semi-persistently scheduled. A set of semi-persistent communication resources may be reserved for use by priority traffic. If not used for priority traffic, the semi-persistent resources may be scheduled for use by other types of traffic. As priority traffic is identified, the priority traffic may be transmitted using the semi-persistent resource without having those communication resources granted by a scheduling entity. Such grant-less access to the semi-persistent resources may result in interference between the scheduled traffic and the priority traffic communicated without first scheduling the specific communication resources. To mitigate interference between different traffic types, a user equipment (UE) may transmit a device-to-device silencing message to other UEs. Upon receiving the silencing message, the other UEs may release any scheduled communication resources that at least partially overlap with the semi-persistent resources.

Abstract: Aspects of the present disclosure provide for various methods and apparatuses for mitigating intra-cell interference when multiplexing grant-less traffic and grant-based traffic. When a wireless device transmits data without first requesting a grant of certain network resources from a base station, such data transmission may be called grant-less traffic in this disclosure. Different from grant-less traffic, when a wireless device needs to request a grant of certain network resources before transmitting data, such data may be called grant-based traffic in this disclosure.

Abstract: Aspects of the disclosure relate to back-off mechanisms for fair joint access of an unlicensed sidelink channel. Each sidelink device may perform independent and asynchronous listen before talk (LBT) of the unlicensed sidelink channel with a respective back-off timer initialized with a back-off value selected to provide fair access to the unlicensed sidelink channel by both active sidelink devices and other devices utilizing the unlicensed sidelink channel. In some examples, the back-off value may be selected based on an estimated number of active sidelink devices. The estimated number of active sidelink devices may be determined, for example, by monitoring distributed handshake signaling on the unlicensed sidelink channel.

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: Methods, systems, and devices are described for techniques for downlink (DL) scheduling and uplink (UL) scheduling in a shared radio frequency (RF) spectrum band. In some aspects, a wireless communication device may receive an UL data transmission grant associated with a channel of shared RF spectrum band. The wireless communication device may perform a channel readiness procedure associated with the channel. The wireless communication device may also transmit channel readiness information based at least in part on the channel readiness procedure to a base station. The channel readiness information may be transmitted via an uplink channel of a licensed RF spectrum band different from the shared RF band. In other aspects, a base station may schedule a data transmission on one or more channels of a shared RF spectrum band. The base station may transmit a data transmission grant for the scheduled data transmission to a wireless communication device.
