Abstract: Aspects of the present disclosure describe an indication channel for wireless communications that indicates whether an ultra-reliable low-latency communication (URLLC) transmission is present in a current mini-slot within an enhanced mobile broadband (eMBB) slot. A base station may determine that an indication message is to be transmitted within the eMBB slot. The indication message may indicate that at least a portion of the mini-slot of the eMBB slot is used for the URLLC transmission. The base station may allocate one or more resources to an indication channel in a same mini-slot as the portion of the mini-slot to be used for the URLLC transmission. The base station may transmit the indication message during the mini-slot on the indication channel using the allocated one or more resources. A UE may receive the indication channel and process at least the portion of the mini-slot based on whether the indication message is received.

Abstract: Methods, systems, and devices for wireless communication are described 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 the semi-persistent resources are 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 collisions between the scheduled traffic and the priority traffic.

Abstract: Methods, systems, and devices for wireless communication are described for SPS for low-latency communications. A wireless communication device may establish a block of semi-persistent scheduling (SPS) resources in each of a plurality of transmission time intervals (TTIs) for transmission of priority traffic, and determine that a level of priority traffic to transmit during a first TTI of the plurality of TTIs is below a priority traffic threshold. The wireless communication device may transmit a per-TTI release signal to indicate that the block of SPS resources in the first TTI is released from being reserved for priority traffic.

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: Methods, systems, and devices for wireless communication are described. A first UE and a second UE may coordinate to establish a sidelink connection. The first UE may identify data to transmit to the second UE, and the first UE may transmit a request to send (RTS) message to the second UE with a first transmit power. The first UE may then determine to refrain from using the first transmit power for the data transmission, and the first UE may transmit the data to the second UE with a second transmit power that is different from the first transmit power. The UE may determine the second transmit power for the data transmission based on instantaneous channel quality information (CQI) received in a clear to send (CTS) message, a modulation and coding scheme (MCS) selected for the data transmission, a threshold power, etc.

Abstract: An apparatus may configure x subframes with a subslot configuration that includes y subslots, y being greater than x. In an aspect, each subslot of the y subslots may include a first portion having one or more symbols for carrying at least one of data or control information, a second portion having a gap, and a third portion for carrying ACK/NACK information associated with the first portion. In an aspect, the second portion may be between the first portion and the third portion. In an aspect, the second portion and the third portion may include at most one symbol. The apparatus may send information indicating the subslot configuration to at least one neighboring base station. The apparatus may communicate content with a user equipment (UE) during at least one of the y subslots.

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.

Abstract: A first apparatus may perform a clear channel assessment (CCA) in a first band-operation of a first radio access technology (RAT) in the first band may be synchronized with operation of a second RAT in a second band. The first apparatus may determine whether the CCA indicates that the first band is occupied. The first apparatus may send a first switching signal in the second band based on a determination that the CCA indicates that the first band is occupied. The first apparatus may send data in the second band after the first switching signal is sent. A second apparatus may perform a CCA in a first band-operation of a RAT in the first band may be synchronized with operation of a second RAT in a second band.

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.

Abstract: A first apparatus may send, to a base station, a set of channel quality indicators associated with a set of channels. The first apparatus may monitor sets of control channel elements in a search space based on the set of channel quality indicators sent to the base station. A second apparatus may receive, from a first user equipment, a set of channel quality indicators associated with a set of channels. The second apparatus may send, based on the set of channel quality indicators received from the first user equipment, control information on a physical downlink control channel associated with the first user equipment in a search space specific to the first user equipment.

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: 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: Various techniques provide for identifying and transmitting a first transmission to a UE in a first transmission time interval (TTI), and puncturing a portion of the first transmission with a higher priority second transmission that has a shorter TTI than the first TTI. The punctured portion of the first transmission may then be transmitted in a subsequent portion of the first TTI, concurrently with an originally allocated portion of the first transmission for that subsequent portion of the TTI. A UE may identify the punctured portion of the first transmission, and identify that the punctured portion of the first transmission is being transmitted in the subsequent portion of the first TTI. The UE may decode the received transmissions and merge the punctured portion with other, non-punctured, portions of the first transmission.

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.

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 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.
